Description

earwax removal device

technical field

The present invention relates to an earwax removal device, and more particularly, relates to an earwax removal device capable of safely and effectively removing dry earwax of Easterners, wet earwax of Westerners and animal earwax.

Background technique

Earwax has an important physiological role in inhibiting the invasion of external germs and bacteria that invade through the ear and minimizing infection.

Since the skin in the ear (ear canal) moves due to the natural movement of the temporomandibular joint and surrounding muscles when a person speaks or chews food, earwax can be removed from the skin in the ear even without artificial removal. It falls off and is slowly pushed from the inside of the ear to the outside by the continuous movement of the skin.

Therefore, artificial removal of earwax is not recommended medically. This is more in line with wet earwax in Westerners than in Easterners, who mainly use cotton swabs when removing earwax, which pushes the wax deep into the ear and increases the risk of side effects.

However, despite such medical understanding and advice, earwax removal is arguably a matter of personal choice in relation to personal hygiene, especially as contrary to medical instructions that, in general, earwax will persist for a long time if it is not artificially removed Staying in the ear not only feels oppressive and foreign body sensation, but also causes discomfort and skin irritation when moving. When the amount of earwax in the ear accumulates to a certain extent, it becomes very necessary to remove the earwax.

As a result, people in most cultural circles of the world have been removing earwax for a long time, and even now, most people in the world regularly remove earwax in their daily lives.

Although people generally want to remove earwax, the traditional types of ear picks and cotton swabs or similar earwax removal tools for removing earwax that are being sold in the international market cannot allow the user to directly see the inside of the ear, but only rely on sensation to remove earwax, There are therefore limitations in effectively and safely self-removing earwax. In addition, for the elderly and young children with relatively poor fine force control ability, excessive force may be applied to the surface of the ear skin due to mishandling of the tool, resulting in skin wounds or inflammation, and in the case of inserting the tool too deeply , may damage or puncture the eardrum.

In order to solve the problem of not being able to see the inside of the ear by yourself, an earwax removal tool with a built-in USB-type small camera has been developed recently, but the disadvantage is that the desire to completely remove earwax will be increased because you can see the inside of the ear by yourself , the psychology of wanting to remove excess earwax may play a role. Moreover, manual operation is still required to remove earwax, so the safety of operation cannot be guaranteed, and the safety problem when the elderly or young children use it remains unresolved.

In addition, the vacuum suction type earwax remover improves the inconvenience of manual earwax removal in the form of automatic removal by vacuum suction, and at the same time has a safety design to prevent the tip of the removal tool from entering the deep ear, but due to the need to generate enough Vacuum suction, so can only fully increase the vacuum suction pressure or reduce the suction port area.

Increasing the vacuum pressure increases the potential risk of injury to the eardrum, so only the lowest pressure levels should be used, with a relative increase in suction by reducing the suction port area. Therefore, its disadvantage is that when the suction port is not accurately aligned with the position of the earwax inside the ear, the removal efficiency becomes extremely low due to the small suction pressure, especially for the wet earwax of Westerners, the removal efficiency is greatly reduced or almost impossible to remove.

The end of the traditional type of ear pick is in the shape of a spoon with a diameter of several mm, so it has a structure that is easy to pull out dry and oily earwax, and the handle part connected to the end is also designed to be about several mm The extremely slender structure makes it easy to insert inside the ear. The material is mainly a relatively hard material such as metal, wood, and plastic, and a material capable of applying sufficient force to the skin surface by bringing the tip of the tool into contact with the skin surface inside the ear is used.

But such end structures and materials can create considerable stress on the skin surface. The contact part between the tip structure and the skin surface is mainly the edge of the spoon-shaped structure. Since the force applied to the contact part at this time is in the range of hundreds of g to several kg, several to several Ten MPa high pressure.

Therefore, if the force applied to the skin surface is not finely controlled, damage to the skin surface may cause inflammation, accompanied by great pain. In addition, since the inside of the ear cannot be directly seen, the earwax can only be removed by feeling, and even if the earwax is removed with the help of others, the field of vision is extremely limited, and in fact, only the feeling or only the outer part of the ear canal can be removed. See earwax. Especially for people who are very sensitive to external stimuli due to poor skin condition, or the elderly or young children who are more sensitive to stimuli, they may feel very irritated, so it is necessary to develop a product that hardly irritates the skin, and Very comfortable earwax removal tool that removes earwax automatically.

At the same time, unlike Asians, among Westerners, 92.4% of whites and 96.9% of blacks, 98% of Europeans have waxy oily earwax (wet earwax), and about 50% of 65-year-olds have periodic Cerumen impaction is a condition in which the ear is completely blocked by wax every few months. (J.AmAcad Audiol 1997 8(6) 391-400)

The basic symptom of cerumen embolism is that the ears feel very stuffy, and according to the report of the otolaryngology department, it produces about 20dB of hearing loss, which leads to great problems in communication. Therefore become the main obstacle of old people's daily life, and need to go to the hospital regularly to accept the service of earwax removal, therefore also bring sizable economic loss. Therefore, in order to prevent cerumen embolism in the elderly with symptoms of cerumen embolism, it is necessary to develop an intelligent earwax removal device technology, which can monitor the number of earwax removal in a certain period of time for personal hygiene management of earwax removal. .

On the other hand, unlike humans, regular removal of earwax is recommended for pets such as dogs and cats. To remove earwax from pets, mechanical tools in the form of cotton swabs and liquid-type earwax dissolvers are mainly used. As with humans, liquid-type earwax dissolvers are recommended, but there are many inconveniences when using this method, so mechanical tools in the form of cotton swabs are often used mainly. However, when using a cotton swab-like tool, there is a side effect of pushing earwax into the ear when the tool is inserted, and it is difficult for the user to insert it to a safe depth based on feeling. Therefore, it is necessary to develop a safe and convenient earwax removal tool that can set a safe depth according to the body shape of the pet, and can make the pet feel comfortable.

The earwax removal device 10 of the first embodiment of the present invention may include a bag part 100 , a head part 200 and a pump 300 .

The bag portion 100 may include a collection hole 111 and a discharge hole 121 .

And, the bag part 100 may include a contact 110 having a collection hole 111 supported in contact with a user's ear hole, and an earwax holder 120 having a discharge hole 120 .

In addition, the bag part 100 may further include a first connection part 130 connecting the contact part 110 and the main body part 400 .

More specifically, the contact 110 may include a collection hole 111 and a mounting hole 112 formed in an opposite direction of the collection hole 111 .

The inside of the contact piece 110 is formed hollow, and is inclined so that the cross-sectional area increases from the collection hole 111 to the mounting hole 112 side.

The contact 110 may have a conical shape, but is not limited thereto.

In particular, the collection hole 111 may be inserted into the ear hole to be in close contact with the inner wall surface of the ear hole. For example, it may be formed as a contact corresponding to the insertion of an earphone into an ear hole.

Wherein, the contact member 110 may be formed of rubber material. The rubber material may include, for example, ordinary rubber, synthetic rubber, soft rubber, etc., but is not limited thereto.

Therefore, by forming the contact piece 110 having the collecting hole 111 directly in contact with the user's ear hole by a rubber material, there is an effect of making it fit more closely to the user's ear hole.

As described above, by being closely attached to the collection hole 111 of the ear canal, the earwax removed from the wall of the external auditory canal is not discharged to the outside, but can flow into the inside of the device more easily.

In addition, the earwax holder 120 may include a discharge hole 121 provided to discharge air and an opening portion 122 with one end open. More specifically, the earwax receiving member 120 may have an opening portion 122 that is open at one end, and a discharge hole 121 is formed in a direction opposite to the opening portion 122 . A plurality of discharge holes 121 may be formed, and a mesh member (not shown) may be provided on the plurality of discharge holes 121 . By forming a mesh in each discharge hole 121 as described above, it is possible to prevent earwax from leaking to the outside.

As mentioned above, the head 200 is connected to the pump 300, the pump 300 is connected to the motor 500 through the connector 510, the motor 500 is connected to the driving part 600, and driven by the driving part 600, the motor 500, the pump 300 and the head 200 move forward or Swipe back.

And, the motor 500, the pump 300, and the head 200 are integrated through the connector 510, and move forward or backward simultaneously at a predetermined speed through the driving part 600 (ie, the linear guide).

In particular, the rotational force transmitted from the motor 500 rotates the pump 300 through the connector 510 , thereby rotating the head 200 connected to the pump 300 .

Therefore, the head 200 can move to the inside of the user's external auditory canal through the driving part 600 , and at this time, the depth of movement to the internal of the external auditory canal is about 15 mm to 20 mm.

As mentioned above, the head 200 enters the user's external auditory canal at a predetermined speed, starts scrubbing from the entrance of the ear hole, and goes back and forth between certain depths in the external auditory canal to continuously remove earwax.

In particular, by limiting the depth of entry of the head 200 to approximately 15 mm to 20 mm, only the earwax pushed outside the external auditory canal is removed, thereby maintaining the physiologically positive function of the earwax formed inside the external auditory canal as much as possible.

Elderly and disabled people who have difficulty adjusting fine power and movements, or users who are sensitive to skin irritation, may feel severe pain when moving quickly with the head 200 in contact with the skin. Therefore, the speed at which the head 200 advances and retreats inside the external auditory canal is automatically adjusted slowly and surely by the driving unit 600 , so that the user does not feel too much discomfort, and the user's earwax can be automatically removed.

In addition, a battery 700 may be disposed inside the main body 400 , and is electrically connected to the pump 300 , the motor 500 and the driving unit 600 to supply power.

FIG. 3 is a diagram for explaining a head 200 according to a first embodiment of the present invention.

The head portion 200 in FIG. 3 has an air injection hole 201, and includes a scrub head 210 bent and formed to contact the wall of the external auditory canal.

The scrubbing head 210 is formed in an arc shape at one end of the head 200 , contacts and scrubs the wall of the external auditory canal, and separates the earwax of the user from the wall of the external auditory canal.

In addition, the head 200 may further include a flow path member 203 having an air passage connected to the air injection hole 201 .

The flow path member 203 may be formed to have a prescribed length so that the scrub head 210 may be inserted into the ear canal to a prescribed depth to remove earwax.

One side of the flow path member 203 is connected to the pump 300 to move the fluid. Thus, the air supplied by the pump 300 passes through the air channel of the flow path member 203 , passes through the air injection hole 201 , and is discharged into the external ear canal.

Wherein, the head 200 may further include a second connecting part 220 connecting the pump 300 and the flow path part 203 .

The second connection part 220 may have a prescribed length, and may form a flow path inside so that air supplied by the pump 300 flows to the flow path part 203 .

Especially, in the first embodiment of the present invention, protrude and form the tip (tip) 250 of spoon shape (spoon) at the curved end (that is, the part that is formed with the air spray hole 201 of discharging air) of scrubbing head 210, can scrape. Rub the wall of the external auditory canal and is suitable for digging out waxy earwax.

The head 200 of the first embodiment of the present invention can effectively remove dry and oily earwax, especially the tip 250 of the scrubbing head 210 is preferably formed as a curved surface (curved surface) towards the outside of the ear, so that it can be pulled out or dug more effectively. Waxy, oily earwax. And, the tip 250 may be formed in a shape including a plurality of corners.

Preferably, the cross-sectional area of the tip 250 is minimized so as to prevent the tip 250 of the scrub head 210 from pushing earwax when the head 200 enters the interior of the external auditory canal. For this reason, preferably, the width D of the curved surface of the tip 250 cannot be too large compared to the cross-sectional width d of the tip 250 . For example, the width D of the curved surface of the tip 250 is preferably about 130% of the cross-sectional width d of the region where the air injection hole 201 is formed (D/d = about 130%).

In FIG. 3 , unexplained reference numeral 250 a is a fin protrudingly formed in a direction opposite to a direction in which the tip 250 protrudingly formed from the end of the scrub head 210 is formed.

When the scrubbing head 210 enters the inside of the external auditory canal and rotates to the left (or right) at a specified angle, and then withdraws to the outside of the external auditory canal, the tip 250 pulls out or digs out the earwax, and the fins 250a can further pull out or dig out the surrounding earwax.

FIG. 4 is a modified example of the head 200 of FIG. 3 .

Compared with the head 200 of FIG. 3 , the head 200 of FIG. 4 not only does not have the fin 250a, but also has a slightly different shape of the tip 250 . Wherein, the difference in shape is that the end of the tip 250 of the head 200 in FIG. 3 has an angular shape with an apex, while the end of the tip 250 of the head 200 in FIG. 4 is arc-shaped.

Although there is no wing 250a on the head 200 of FIG. 4 , the tip 250 of the head 200 of FIG. 4 may also be formed with the wing 250a as shown in FIG. 3 .

As mentioned above, the head 200 in FIG. 3 and FIG. 4 is provided to be exposed to the outside through the collection hole 111 , and can be disposed in the bag portion 100 so as to pass through the contact piece 110 and the first connection piece 120 . In particular, the cross-sectional area of the collection hole 111 may be formed larger than the cross-sectional area of the head 200, and the head 200 is configured to have a predetermined interval from the edge of the collection hole 111, so that the earwax passes through a predetermined area formed by the predetermined interval, and passes through the collection hole. 111 to flow into the cerumen holder 120 .

In particular, the scrubbing head 210 and the flow path member 203 may be formed of soft or hard materials. At this time, the soft and hard materials may generally have a Shore A hardness of 30 to 90. More specifically, the head portion 200 may be formed of a soft or hard material generally having a Shore A hardness of 30 to 90 so as to constantly control the contact force with the wall of the external auditory canal (ie, the skin surface) at a prescribed magnitude.

In particular, the flow path member 203 bent toward the wall of the external auditory canal is made of soft or hard material with elastic recovery force, so that when the scrubbing head 210 connected to the flow path member 203 contacts the wall of the external auditory canal, according to the size of the user’s external auditory canal When the flow path element 320 is unfolded, the elastic potential energy can be accumulated through the bending stiffness of the flow path element 203 .

The elastic potential energy is applied to the wall of the external auditory canal in the form of elastic contact force through the scrubbing head 210 in contact with the wall of the external auditory canal.

That is, the flow path member 203 is made of a soft or hard material with a predetermined stiffness (stiffness), and is formed to bend toward the wall of the external auditory canal at a predetermined angle, so that the scrub head 210 can be easily contacted with the wall of the external auditory canal, and the flow path member 203 passes through the wall of the external auditory canal. Even when fully expanded by the user's force, the elastic contact force applied to the wall of the external auditory canal can be limited to a predetermined value or less.

Therefore, when the flow channel member 203 is fully expanded under the action of the user's force and the wall of the external auditory canal, the elastic contact force applied to the wall of the external auditory canal becomes the maximum value. Minimize physical irritation caused by scrubbing the wall of the external auditory canal.

Wherein, for example, soft and hard materials can be silicone rubber (Silicone Rubber), thermoplastic rubber (TPR, Thermoplastic Rubber), polyvinyl chloride (PVC, Polyvinyl Chloride) and polyurethane (PU, Polyurethane), but not limited to this.

The head 200 can be rotated forward or backward by the motor 500 at preset standard angle intervals, each preset standard angle is one step, and the forward or reverse rotation can be repeated multiple times within one step of rotation.

That is, when the head 200 rotates in the forward rotation direction, forward rotation and reverse rotation can be repeated multiple times within one rotation, and 360-degree forward rotation can be completed. On the contrary, when rotating in the reverse direction, forward rotation and reverse rotation can be repeated many times in one step rotation, and a 360-degree reversal can be completed.

For example, when the set standard angle is 5° (degree), set 5° (degree) rotation as one step (Step), divide 360° (degree) into 72 steps of rotation, and each step of rotation can be repeated multiple times Rotate forward or reverse.

That is, the inner circumference of the external auditory canal is divided into 72 areas, and forward rotation and reverse rotation can be repeated in each fan-shaped circle with an angle of 5° (degrees). In particular, forward rotation and reverse rotation can be repeated about 5 times, but Not limited to this.

As described above, when forward rotation is completed by repeating forward rotation and reverse rotation in 72 fan-shaped circles, forward rotation and reverse rotation can be repeated about 5 times in the reverse direction within 72 fan-shaped circles to complete reverse rotation.

As mentioned above, the scrubbing head 210 rotates 360 degrees forward and backward along the circumferential direction of the external auditory canal wall to scrub the external auditory canal wall, thereby reducing the adhesion of oily earwax firmly attached to the inner wall of the external auditory canal and the fastening of dry earwax. Force (Interlocking).

At this time, the air is discharged to the wall of the external auditory canal through the air injection hole 201, so that the earwax can be removed more easily.

The present invention can minimize the physical stimulation of the skin surface and remove the earwax when air pressure is applied through the air injection hole 201 to remove the earwax attached to the wall of the external auditory canal.

However, when the earwax is firmly attached to the skin surface of the external auditory canal, it is difficult to completely remove the earwax by only applying air pressure. Therefore, by carefully scrubbing the entire area of the external auditory canal wall using the scrubbing head 210 protrudingly formed with the tip 250 while applying air pressure through the air jet hole 201, it is possible to remove earwax more simply and quickly.

The above-mentioned dry earwax is easily broken under mechanical pressure, so it may easily fall on the surface of the external auditory canal just by scrubbing, and can be easily discharged to the pocket 100 by the air jet pressure.

The above-mentioned oily earwax is quickly dried by the air discharged through the air injection hole 201 of the present invention, and surface tension is generated along the boundary line of the earwax attached to the skin, so that the earwax can be easily separated from the skin.

Therefore, the oily earwax can be easily separated from the skin by the jet of air, while becoming similar to dry earwax by the drying process, and easily crushed by the action of scrubbing.

That is, the head 200 performs scrubbing action and sprays air at the same time, so that the removal efficiency of dry and oily earwax can be improved.

And, as described above, the scrubbing action of the head 200 separates the cerumen from the skin surface of the external auditory canal and discharges it to the outside of the external auditory canal to collect it in the bag part 100 by using the minimum physical force generated by the limited contact force.

Fig. 5 is a diagram for explaining the use status of the earwax removal device according to the first embodiment of the present invention.

Referring to FIG. 5 , the head portion 200 of FIGS. 3 and 4 may be configured to be bent toward the wall of the external auditory canal, so that at least a part of the area is in contact with the wall of the external auditory canal. More specifically, the flow path member 203 is set to bend toward the wall of the external auditory canal, so that the scrubbing head 210 of the head 200 is in contact with the wall of the external auditory canal.

When the collection hole 111 side comes into contact with the user's ear, the air discharged from the air injection hole 201 collides (blocks) with the tip 250 , flows through the user's external auditory canal wall, and moves toward the discharge hole 121 side through the collection hole 111 .

More specifically, the air discharged from the air injection hole 201 flows into the opening 122 of the earwax holder 120 connected to the mounting hole 112 through the collection hole 111 together with the user's earwax, the earwax is stored in the earwax holder 120, and the air passes through the earwax holder 120. The discharge hole 121 is discharged to the outside.

In particular, the air injection hole 201 is formed to have an angle in the range of 45 degrees to 90 degrees with respect to the virtual central axis of the head 200 in the longitudinal direction.

As described above, the air ejection hole 201 is formed so that the air discharged through the air ejection hole 201 collides with the tip 250 to flow toward the collecting hole 111 side.

Therefore, the earwax adhered to the wall of the external auditory canal is pushed to the outer side of the earhole (collection hole side) by the air pressure discharged through the air injection hole 201, so that the earwax can be removed.

At this time, the generated air pressure may be approximately 7 kPa to 14 kPa, or 9 kPa to 11 kPa, or less than or equal to 10 kPa, but is not limited thereto.

As described above, by forming the scoop-shaped tip 250 at the end of the scrub head 210, the air can be discharged to the outside of the ear hole (collection hole side), so the problem that the pressure is directly applied to the eardrum can be fundamentally prevented. In addition, it is possible to prevent the air pressure that may be applied to the eardrum from causing discomfort to the user or the like.

In addition, by exhausting the air as described above, there is an effect of removing and evaporating moisture that flows into the user's ear when the user washes or takes a bath.

The automatic earwax removal device 10 of the first embodiment of the present invention used as described above may further include a water supply device (not shown) for supplying water by spraying a small amount of water to the wall of the external auditory canal.

As mentioned above, when the water is supplied by the water supply device, the fastening force of the dry earwax is weakened by the supplied water to reduce the pain when removing the earwax, and the scrubbing effect of the scrub head 210 can be improved.

Wherein, the water may include physiological saline, water, etc., but is not limited thereto.

Fig. 6 is a diagram for explaining the operation of removing dry earwax by the earwax removing device according to the first embodiment of the present invention.

Dry earwax may move inside the ear canal as it attaches to or breaks off the skin surface of the ear canal.

Therefore, for the dry earwax attached to the surface of the skin, it needs to be detached from the surface of the external auditory canal by physical friction. clear.

For this reason, the earwax removal device according to the first embodiment of the present invention repeats forward and reverse rotation of the scrubbing head 210 in a unit sector (unit sector, unit arc) with a specified internal angle (δ), and through physical friction Removes dry earwax from the wall of the external ear canal. At the same time, blowing is used to remove the earwax falling off the wall of the external auditory canal into a device connected to the external auditory canal.

At this time, the scrubbing head 210 enters from the periphery of the outermost edge of the external auditory canal (the outer side of the ear) where the dry earwax is formed, and removes the earwax.

The circumference of the external auditory canal (circumference) can be divided in units of specified internal angles (δ), and the scrubbing head 210 performs actions on all unit sectors sequentially in the same way to remove dry earwax in the external auditory canal.

When the earwax (for example, dry earwax) of a whole circumference (for example, dry earwax) is removed, the scrub head 210 is introduced into the inner side of the external auditory canal at a unit depth, and the dry earwax of other circles is removed in the same way using the tip 250 .

When the above method is applied to all the circumferences of the external auditory canal, dry earwax can be removed from the surface of the entire external auditory canal (assumed to be a cylinder: ear canal cylinder) at a depth of about 15 mm.

The above-mentioned dry earwax removal operation will be further described below.

The action of the earwax removal device according to the first embodiment of the present invention can be roughly controlled by two parameters.

The first parameter is the angle (δ) of the unit sector (Unit sector), and the second parameter is the scrubbing speed at which the scrub head 210 scrubs the wall of the external auditory canal according to the angle of the unit sector (Unit sector).

Wherein, the angle (δ) of the unit sector (Unit sector) is roughly in the range of 5°˜20°.

When the angle of the unit sector is less than 5°, the time required to scrub the wall of the external auditory canal increases, and there is a problem that it is difficult to remove earwax efficiently. When the angle of the unit sector is greater than 20°, the frictional force acting on the wall of the external auditory canal increases, and There is a problem with accidental skin irritation of the wall of the external auditory canal.

In addition, the scrubbing speed is approximately 5 mm/s to 50 mm/s. When the scrubbing speed is less than 5mm/s, the time required to scrub the wall of the external auditory canal increases, and there is a problem that it is difficult to remove earwax efficiently. When the scrubbing speed is greater than 50mm/s, the friction acting on the wall of the external auditory canal increases, and there is The wall produces the problem of accidental skin irritation.

However, this is only an example for ease of description, and the physical conditions of the scrubbing head 210 for simultaneously satisfying these two parameters need to be considered, and various deformations can be carried out according to the needs of users, which is not the scope of rights of the present invention. limit.

Fig. 7 is a diagram for explaining the operation of removing oily earwax by the earwax removing device according to the first embodiment of the present invention.

Oily (moist) earwax is secreted relatively more from the cerumen glands on the wall of the external auditory canal, so it has accumulated before it dries and presents a wet nature, and is formed by accumulating wider and thicker in the space of the external auditory canal.

Therefore, it is more effective to dig out or pull out the accumulated earwax from the outside of the ear canal little by little than physical friction.

In addition, oily earwax is different from dry earwax and accumulates in the form of blocking the entire ear hole. Therefore, when the scrub head 210 enters, it is necessary to prevent the tip 250 of the scrub head 210 from pushing the earwax inside as much as possible.

Therefore, when the scrubbing head 210 is introduced into the external auditory canal for the first time (initially), as shown in FIG. , rotate to the right (or left) according to the inner angle (δ), move to the "first track (1st track)", and then move the scrub head to the outside of the external auditory canal through the first track, so as to remove the earwax on the first track through the tip 250 . In fact, when using the earwax removal device, the scrub head 210 cannot be introduced into the "0th track" (0st track) every time, so it is only necessary to understand the first entered track as the "0th (zero) track". That is, it can be understood that the position of the "0th (zero) track" is variable rather than fixed.

Then, when the scrubbing head 210 is introduced into the external auditory canal for the second time, enter the same depth through the first track that has been cleared once, and then rotate to the next track (second track) to enter. After entering the second track, move the scrub head 210 to the outside of the external auditory canal, thereby removing the earwax in the second track.

As mentioned above, when entering the second track, the same depth is entered only through the first track, and the first track removes most of the earwax through the previous clearing, so there is no need to push the earwax of the second track inside when entering of great advantage.

By repeating the above-mentioned method, it is possible to remove oily earwax on all orbits of a circumference (ie, a circumference that enters a position of a prescribed unit depth).

After removing the oily earwax in all orbits of the outermost first external auditory canal circumference as described above, increase the depth of entry by unit depth, and remove the oily earwax in all orbits of the second circumference as described above.

Applying the above method sequentially to the entire cylinder of the external auditory canal minimizes the inward pushing of oily earwax and at the same time removes oily earwax very effectively.

The 5 mm mentioned in the above description of FIG. 7 is just an example and is not limited thereto.

In other words, the action of removing earwax can be performed as follows: the head (especially the scrubbing head 210) enters the wall of the external auditory canal divided into multiple tracks at a preset unit depth through any one of the multiple tracks, and passes through a certain angle (δ) After the rotation moves to the adjacent track, it retreats to the outside of the external auditory canal through the adjacent track. More specifically, when performing cerumen removal, the head (especially the scrubbing head 210) enters a preset unit depth through any one of a plurality of tracks when entering for the first time, and then passes through the adjacent track after rotating to the adjacent track. Retreat to the outer side of the external auditory canal, from the second entry to the last entry, enter the same depth through the previously retreated track and rotate to the adjacent track, and then retreat to the outer side of the external auditory canal through the adjacent track.

In addition, the head (especially, the scrubbing head 210 ) may repeatedly perform the above-mentioned clearing action on all tracks at the current depth entered, and all tracks at subsequent depths entered at a unit depth thereafter.

Explain again the action of removing oily earwax by using the above head (especially the scrubbing head 210), the earwax can be removed through the following steps: advance step, introduce the head (especially the scrubbing head 210) into the external auditory canal according to the preset depth of stage 1 ; Rotation step, advance 1 stage depth and then rotate according to a preset angle, contact the front end of the scrubbing head with the external auditory canal wall of the hypothetical first track; retreat step, make the front end of the scrubbing head contact the inner wall of the external auditory canal by rotating Retreat to the inside of the pocket in the state, scrape and remove the earwax on the inner wall of the hypothetical first orbit; the first deep earwax removal step, repeatedly perform the entry, rotation and retreat of the hypothetical orbit through the removed earwax, and remove the 360-degree of the wall of the external auditory canal The earwax of the corresponding imaginary track; the steps of removing earwax, when the first depth of earwax removal is completed, after entering the preset second depth, repeatedly perform forward, rotation, and backward to remove the second depth of earwax, and follow the preset Repeat the above steps for the desired depth.

Fig. 8 is a diagram for explaining important parts of an earwax removal device according to a second embodiment of the present invention.

Compared with the earwax removal device of the second embodiment of the present invention shown in FIG. 8 and the earwax removal device of the first embodiment of the present invention described with reference to FIGS. The constituent elements are similar.

Therefore, the earwax removal device of the second embodiment of the present invention can be said to be an automatic earwax removal device, but the brush 252 is also sufficient for a manual earwax removal device.

The brush 252 may be used to wipe off oily earwax attached to the scrub head 210 (particularly, the tip 250).

According to FIG. 8 , the disc-shaped joint part 251 can be provided on the second connecting part 220 for combining with the bag part 100 . The second connecting member 220 passes through the center of the joint portion 251 .

The brush 252 is disposed on a surface of the joint part 251 . For example, when it is assumed that the bag part 100 and the joint part 251 are combined with each other, the brush 252 may be provided in a direction from one surface of the joint part 251 toward the collection hole 111 side of the bag part 100.

If the second connecting part 220 and the coupling part 251 are press-fitted and coupled to each other, the coupling part 251 rotates as the second connecting part 220 rotates, so that the brush 252 also rotates. On the other hand, if the second link 220 is combined with the joint part 251 in a state that the joint part 251 does not rotate even if the second link 220 rotates, the brush 252 does not rotate even if the second link 220 rotates.

Of course, the joint portion 251 may be formed at one end of the main body portion 400 as required.

When the bag portion 100 is coupled to the coupling portion 251 , the brush 252 appears to be accommodated in the bag portion 100 .

Also, the pocket part 100 and the coupling part 251 may be coupled or separated from each other by an insertion coupling or by a magnetic coupling. For example, for the combination method by magnetic force, for example, a metal with a predetermined width can be provided on the inner peripheral surface of the end of one side of the bag part 100 (that is, the side that can be combined with the joint part 251), and on one side of the joint part 251 (that is, A magnetic strip of a predetermined width is provided on the outer peripheral surface of the end of the side) that can be combined with the bag portion 100 . Of course, the setting positions of the metal and magnetic strips can be changed.

When the scrub head 210 is introduced into the inside of the external auditory canal, the tip 250 of the scrub head 210 returns to the inside of the bag part 100 in a state filled with oily (wet) earwax.

At this time, wipe and remove the oily earwax attached to the tip 250 inside the bag part 100, and then enter the inside of the external auditory canal again, and repeat the above operation several times to effectively remove the oily earwax inside the external auditory canal.

If the brush 252 does not rotate and maintains a fixed position, the surface of the tip 250 with oily earwax attached to the end of the brush 252 is contacted to make the tip 250 rotate (rotation motion), and the oily earwax on the tip 250 can be wiped off very effectively and quickly.

Thus, in the second embodiment of the present invention described above, oily earwax adhering to the tip 250 can be effectively wiped and removed by the brush 252 inside the bag portion 100 .

This method can very effectively and quickly remove thick, highly adhesive oily earwax, and from this point of view, it can greatly improve the performance of the device, especially the removal efficiency.

FIG. 9 is a diagram showing the conversion of the earwax removal device according to the first embodiment or the second embodiment of the present invention into a dryer for the external auditory canal, and FIG. 11 is a drawing illustrating the air direction of the drying head shown in FIG. 10 , and FIG. 12 is a drawing illustrating the miniature muffler shown in FIG. 9 .

The drier for external auditory canal shown in FIG. 9 can be realized by using the earwax removal device according to the first embodiment or the second embodiment of the present invention. That is, after the earwax removal device in the first or second embodiment of the present invention removes the earwax inside the external auditory canal, remove the used scrubbing head 210 and combine it with the special drying head 260 for use.

As shown in FIG. 10 , in the drying head 260 , a plurality of long-hole-shaped air injection openings 261 having a predetermined length are formed in the lateral direction on the trunk portion 264 to dry the entire surface of the external auditory canal more quickly.

In addition, an air injection port 263 for injecting air is formed in the drying head 260 , and the air injected into the air injection port 263 is sent to the air injection opening 261 . For example, an air injection port 263 is formed on the side of the trunk portion 264 of the drying head 260 , and the air injection port 263 is connected to a plurality of air injection openings 261 .

Through the plurality of air injection openings 261, the area of air injection per unit time is larger than that of the scrub head 210 for removing earwax, so that the drying time can be greatly shortened.

Also, a streamlined guide 262 is formed at the front end of the drying dedicated head 260 (for example, the other side of the trunk portion 264 ). For example, the length of the guide 262 is approximately 7 mm, and may be formed to have a length corresponding to the average size of the external auditory canal.

As shown in FIG. 11 , the guide 262 can guide the direction of the air so that the air injected through the air injection opening 261 does not flow toward the eardrum, but flows toward the wall of the external auditory canal and the outside of the ear. For example, the portion of the guide 262 protruding toward the eardrum side is formed, and the portion toward the outer side of the ear is recessed. Thereby, the user's sense of discomfort can be greatly reduced and safety can be ensured. In addition, drying time can be further shortened by spraying warm air.

In Korea, there are about 2 million patients with otitis externa every year, and it occurs in all age groups and the number of patients is almost the same every month, especially in summer, which increases (National Health Insurance Corporation).

In the United States, about 10% of the total population is infected with otitis externa every year, and the cause of the disease is neglect of the moisture and moisture in the external auditory canal after swimming and showering. In addition, the use of metal ear picks, etc. will cause slight damage and inflammation to the skin of the external auditory canal. In summer, cotton swabs can breed bacteria due to high humidity, and the use of such swabs, etc., increases the infection rate.

American and Korean otolaryngologists recommend that you use a hair dryer to dry your ears thoroughly after swimming and showering, but currently you need to prepare a separate hair dryer to dry your ears, and it is difficult to carry a large hair dryer.

Therefore, the external auditory canal dryer of the present invention needs to have the function of a miniature dryer, and can utilize the low-pressure air of the air pump 253 to directly dry the external auditory canal. In addition, a micro heater 255 is built in to control the temperature, and it can be used comfortably by blowing warm air in winter.

Assuming that the scrubbing head 210 shown in FIG.

To minimize heat loss, the micro-heater 255 is located in the outlet channel of the micro-muffler 254 so that warm air can be applied directly to the air injection port 261 of the desiccant head 260 .

The temperature of the air can be controlled by controlling the voltage or current applied to the micro heater 255, and the operating voltage and current of the air pump 253 can be controlled to adjust the air pressure and intensity.

FIG. 9 shows the case where an air pump 253 is additionally provided, and a pump 300 may be used instead of the air pump 253 as required.

On the other hand, for an ultra-small air pump, the diaphragm type air pump 253 is used in consideration of the efficiency of pressure formation, and at this time compressed air will generate aerodynamic noise. This noise is about 50dB, which is equivalent to the noise in a quiet office.

But when such a sound is close to the ear, the volume will feel significantly increased. Therefore, the desiccator for external auditory canal of the present invention includes a miniature muffler (muffler) 254 to reduce the aerodynamic noise by about 10%, thereby reducing the intensity of the noise to about 45dB which does not cause major irritation.

That is, the micro muffler 254 may be provided between the air pump 253 and the micro heater 255 .

As shown in FIG. 12 , the micro muffler 254 forms a porous tube 254 b inside the main body 254 a of the muffler 254 .

Inside the main body 254a of the micro muffler 254, there is a space between the porous pipe 254b and the main body wall, and a sound absorbing material (not shown) can be inserted into this space.

Therefore, the micro muffler 254 can be manufactured by inserting a tubular sound-absorbing material (not shown) made of various fabrics such as cotton yarn and cotton wool into the porous tube 254b, and then inserting it into the micro muffler main body 254a.

When compressed air is applied to the inlet of the micro muffler 254, the impact sound pressure of the compressed air passing through the muffler passes through the multiple air holes of the open porous tube 254b, and is absorbed and dissipated by the sound-absorbing material, the noise is attenuated and the airflow is discharged through the outlet .

Fig. 13 is a diagram for explaining important parts of an earwax removal device according to a third embodiment of the present invention.

The earwax removal device according to the third embodiment of the present invention is used in public places such as hair salons.

Compared with the earwax removal device of the second embodiment of the present invention, the earwax removal device of the third embodiment of the present invention is only different in that the scrubbing head 180 and the bag part 100 are disposable, and other components are similar.

The earwax removal device according to the third embodiment of the present invention is deployed in public places such as hair salons, so the scrubbing head 280 and the bag 100 are preferably disposable.

As shown in Figure 13, the disposable scrubbing head 280 is detachably arranged on the head detachment rod 281, and a soft contact part 270 such as silica gel can be formed on one side of the bag part 100 (that is, the part in contact with the external auditory canal). .

The disposable bag 100 and the scrubbing head 280 can be made by compressing paper. In the process of paper compression molding (papermold), the density, hardness, surface roughness and water absorption of paper can be adjusted, and various forms can be produced according to user preferences to produce more diversified products.

In this way, individuals can hygienically use products in public places, thus enabling personal protection against COVID-19 etc. and producing environmentally friendly disposable products.

Fig. 14 is a diagram showing an example of a cleaning device capable of cleaning a head having a scrubbing head according to an embodiment of the present invention.

In the cleaning device 290 of FIG. 14 , the head 200 can be inserted into the charging stand, and ultrasonic waves can be used for cleaning such as disinfection. Of course, if the scrub head can be separated from the head 200, only the scrub head can be inserted.

There is an extra cleaning container (space) inside the charging stand to place detergent for use, and an opening 291 may be formed in the charging stand to place the end portion of the head 200 that may be attached to earwax residues, etc. (for example, a tip 250 is formed scrub head) and soak in detergent.

An ultrasonic vibrator or the like is placed in the charging stand and connected to the cleaning container, and ultrasonic vibration is applied to detergent to clean the head 200 .

On the other hand, in the earwax removal device of various embodiments as described above, when the tip 250 enters the inside of the external auditory canal, the distance between the tympanic membrane and the tip 250 can be increased by using infrared rays, ultrasonic waves, etc., and cannot be achieved when the distance is too short. Continue to enter the function.

In addition, as an additional function, in order to measure the body temperature, the bag portion 100 can be removed and an infrared body temperature measurement module can be inserted for use.

FIG. 15 is an internal perspective view of the earwax removal device 11 according to the fourth embodiment of the present invention, and FIG. 16 is an exploded perspective view of the earwax removal device according to the fourth embodiment of the present invention. For convenience of description, the same reference numerals are assigned to the same parts as in the above-mentioned embodiment, and the description of the same parts as in the above-mentioned embodiment will be omitted.

More specifically, referring to FIG. 15 and FIG. 16 , unlike the above-mentioned embodiments, the driving part 600 of the earwax removal device 11 according to the fourth embodiment of the present invention can be manually operated.

The drive unit 600 is connected to the head 200 and may include an operating knob 601 exposed to the outside to move the head 200 forward and backward.

More specifically, the driving part 600 may include an operation knob 601 , a return spring 603 and a slide ring 605 .

For example, the operation knob 601 may be formed to protrude from one side of the motor 500 .

In addition, an operation hole 602 may be formed on one side of the main body 400 to expose the operation knob 601 to the outside.

That is, the motor 500 is disposed inside the main body 400, and the operation knob 601 protruding from the motor 500 is exposed to the outside of the main body 400 through the operation hole 602.

The operation hole 602 is formed to have a predetermined length, and can guide the forward and backward movement of the operation knob 601 . That is, the operation knob 601 is provided so as to be able to move forward and backward in the longitudinal direction of the operation hole 602 .

When the user moves the operation knob 601 along the longitudinal direction of the operation hole 602 with fingers, the head 200 connected with the operation knob 601 can advance or retreat inside the external auditory canal. That is, as described above, the head 200 of the present invention is connected to the pump 300, the pump 300 is connected to the motor 500 through the connector 510, and the motor 500 is connected to the operation knob 601, so that when the user moves the operation knob 601, it can move back and forth Motor 500 , pump 300 and head 200 .

In particular, the operating knob 601 may include a sliding ring 605 for easier movement of the operating knob 601 . The slide ring 605 is in contact with the inner peripheral surface of the main body part 400, and may include a plurality of rollers 607 provided to be movable along the inner peripheral surface. The rollers 607 may be spaced apart from each other by a prescribed distance along the circumferential direction of the slide ring 605 .

In addition, the slide ring 605 is disposed on the outer periphery of the motor 500, and when the operation knob 601 is moved, the plurality of rollers 607 of the slide ring 605 rotate and move along the inner peripheral surface of the main body 400, so that the user can move the operation knob 601 more easily. .

In addition, the return spring 603 can be set so that when the user operates the operation knob 601 to move the head 200 forward, the head 200 will automatically return to its original position if the user releases the force of the finger.

As an example, the return spring 603 connects the inner peripheral surface side of the main body 400 and the motor 500, and when no force is applied to the operation knob 601, the motor connected to the return spring 603 moves toward the inner side of the main body 400 (retreating) by the return spring 603 . direction side) to move.

Therefore, ordinary users who are not sensitive to skin stimulation can adjust the speed of forward or backward according to their desired speed, so that the head 200 can move immediately, and can freely control the depth and number of insertions of the head 200 into the external auditory canal. .

In addition, the earwax removal device 11 can set the above-mentioned driving part 600 so that the linear guide, the operating knob 601, the return spring 603 and the sliding ring 605 can be properly arranged to be used according to the user's choice of manual mode or automatic mode.

Wherein, the main body 400 may additionally include a mode selection part (not shown), so that the user can select a manual or automatic mode.

When the user selects the automatic mode, the linear guide is driven to slide the head 200 into the user's external auditory canal at a preset speed, and the head enters the external auditory canal at the set speed, and the scrubbing head and air discharge pressure are used to remove the particles attached to the external auditory canal wall. earwax.

When the user selects the manual mode, the user can directly manipulate the operation knob 601 by hand, and slide the head 200 into the external auditory canal to remove the earwax attached to the wall of the external auditory canal.

In addition, a battery 700 electrically connected to the pump 300 , the motor 500 , and the drive unit 600 to supply electric power may be arranged inside the main body 400 .

In addition, a switch (not shown) for operating the earwax removal device 11 is provided on the outer peripheral surface of the main body 400, and the earwax removal device 11 can be driven according to the on/off operation of the switch.

In addition, a mode selection part (not shown) for selecting the automatic mode or the manual mode of the earwax removal device 11 may be provided on the outer periphery of the main body part 400 . In particular, according to mode selection, the driving unit 600 can be driven in the automatic mode, and can be driven by the user operating the operation knob 601 in the manual mode.

The above earwax removal device 11 of the present invention can be provided with an operating knob 601 on the top of the motor 500, connected to form a linear guide at the bottom of the motor 500, connected to form a pump 300 in front of the motor 500 (pocket side), and connected to the rear of the motor 500 to form a pump 300. The connection forms a return spring 603 .

Therefore, when the driving part 600 is driven, the motor 500 connected to the driving part 600 moves forward, the pump 300 connected to the motor 500 advances inside the device, and the head 200 connected to the pump 300 advances to the outside through the collecting hole 111 and then moves forward. Insert inside the external auditory canal.

At this time, when the user operates the operation knob 601, the motor 500 connected to the operation knob 601 advances, the pump 300 connected to the motor 500 advances inside the device, and the head 200 connected to the pump 300 advances to the outside through the collection hole 111 However, it can be inserted into the external auditory canal, and when the force applied to the operation knob 601 is released, the return spring 603 will retreat to the inside of the device, so that the head 200 can return to its original position.

17 to 23 are drawings for illustrating the remover 900 applicable to embodiments of the present invention. FIG. 17 only shows the part where the remover 900 is provided in the earwax removal device. FIG. Shown bag portion 100, scrubbing head 210 is positioned at the internal state of remover, Fig. 19 is the section of Fig. 18, Fig. 20 is the front view of remover 900, Fig. 21 is the perspective view of remover 900 observed from the rear, Fig. 22 FIG. 23 is a cross-sectional view of the remover 900 to illustrate the application of the remover 900 . For convenience of description, the same reference numerals are assigned to the same parts as in the above-mentioned embodiment, and the description of the same parts as in the above-mentioned embodiment will be omitted.

The remover (remover) 900 among Fig. 17 to Fig. 23 can effectively remove sticky and highly adherent oily ear wax (wet ear wax) (also called wet ear wax) from the tip 250 of the scrubbing head 210 and make it fall into the bag Department 100 interior.

The remover 900 is detachably provided inside the bag part 100 .

Westerners' oily earwax is usually removed by digging out the oily earwax at the tip 250 of the scrubbing head 210. When the remover 900 is used, the oily earwax 12 attached to the tip 250 of the scrubbing head 210 can be effectively dropped and collected. Inside the bag portion 100 .

The remover 900 has a plurality of curved elastic ribs (ribs) 901 with a width d similar to the width of the inside of the tip 250 of the scrub head 210 .

Each elastic rib 901 is formed at one side (for example, the front) of the hollow body of the remover 900 at equal intervals from each other, and is formed with a certain curvature. That is, one end of each elastic rib 901 is integrally formed with the main body of the remover 900 , and the main body of the remover 900 is bent with a certain curvature from one end to the other end of each elastic rib 901 .

At this time, the width of one end of each elastic rib 901 integrally formed with the main body of the remover 900 is greater than that of the other end.

In addition, the other end of each elastic rib 901 is spaced from the other end of the opposite elastic rib 901 by a certain distance. Thus, a through hole 902 is formed in the remover 900, through which the scrub head 210 can be exposed to the outside or enter the inside when the scrub head 210 moves linearly.

The material of the remover 900 may be a soft material with a Shore A hardness of 60-90.

In addition, it can be adjusted by adjusting the hardness of the remover 900, and the thickness T of the elastic rib 901 shown in FIG. The length H in the horizontal direction of the end end determines the stiffness (stiffness) of each elastic rib 901 .

In particular, the stiffness is preferably designed to be less than or equal to the stiffness of the tip 250 of the scrub head 210 . As mentioned above, when the scrubbing head 210 moves linearly in the direction of "+moving direction (moving direction)" as shown in FIG. The oily earwax 12 attached to the tip 250 is effectively pushed and dropped.

Afterwards, the scrub head 210 returned to the inside of the remover 900 moves linearly in the "-moving direction" in order to enter the inside of the external auditory canal. earwax 12, so the oily earwax 12 inside the external auditory canal can be easily scraped off.

Whenever the scrubbing head 210 rotates at a certain angle θ, the tip 250 of the scrubbing head 210 can be in contact with each elastic rib 901 respectively. While in motion, the tip 250 of the scrub head 210 can effectively remove all oily earwax from the entire circumference (360 degrees) of the external auditory canal.

Moreover, when the remover structure of this form is double or more, one linear movement can remove more than two oily earwax, so the effect can be increased by more than two times.

24 to 26 are diagrams for explaining the operation of the earwax removal device according to the fourth embodiment of the present invention.

In the earwax removal device in which the user moves the operation knob 601 to make the head (in particular, the scrub head 210) move linearly (+,-moving direction (moving direction)) to remove earwax (for example, oily earwax), in order to remove the cylindrical For all the earwax on the wall of the external auditory canal, it is preferable to regularly rotate the scrub head 210 at a certain angle, but when the user directly holds the earwax removal device with his hand and then rotates the earwax removal device for use, it is not only difficult to operate the operation knob 610, but also difficult to clean it at a certain angle. Rotate the scrub head regularly.

Especially, for the earwax removal device that the user moves the operation knob 601 to make the scrub head 210 linearly move (+,-moving direction (moving direction)) to remove earwax, when the tip 250 of the scrub head 210 enters the external auditory canal, due to the anatomical characteristics of the ear It collides with the inlet-side and outlet-side projections of the external auditory canal to be caught (see FIG. 24 ). This leads to a rejection reaction from users.

Therefore, in the present invention, whenever the tip 250 is close to the entrance side of the external auditory canal in order to enter the inside of the external auditory canal, the scrub head 210 (see FIG. It is stuck on the protrusion at the entrance of the external auditory canal, and can enter the interior of the external auditory canal (refer to FIG. 26 ). For example, use infrared and/or ultrasonic sensors to sense the distance between the entrance of the external auditory canal and the tip 250, and if it is within a certain distance, then rotate the scrubbing head 210 at a predetermined angle (for example, about 10 degrees to 30 degrees), So that the tip 250 is not stuck in the protrusion at the entrance of the external auditory canal, but can enter the interior of the external auditory canal.

In this way, in the present invention, the user does not need to rotate the earwax removal device himself, and the movement of the operation knob 601 is sensed by an internal sensor (not shown) (for example, a position sensor, an infrared sensor, etc.) The scrubbing head 210 can be automatically rotated at a prescribed angle.

In other words, as an example of the method of removing earwax according to the fourth embodiment of the present invention, whenever the tip 250 of the scrubbing head 210 enters the interior of the external auditory canal and approaches the entrance side of the external auditory canal, the cerumen is wiped at a predetermined angle (for example, 10 degrees to 30 degrees). ) to rotate the scrubbing head 210 to enter the inside of the ear canal. After entering, there is no need to rotate the scrubbing head 210. The user only needs to operate (make it move forward or backward) to operate the knob 601 to make the scrubbing head 210 move forward/backward, and scrape the earwax outside the external auditory canal . In this method, when the user moves the operation knob 601 with fingers (to +, - directions), the scrubbing head 210 of the head 200 connected to the operation knob 601 advances or retreats inside the external auditory canal. Wherein, when the user releases the force on the finger, the head 200 automatically returns to the original position through the return spring 603 .

In addition, as an example of the method of removing earwax according to the fourth embodiment of the present invention, whenever the tip 250 of the scrubbing head 210 enters the interior of the external auditory canal and approaches the entrance side of the external auditory canal, the earwax is wiped at a predetermined angle (for example, 10 degrees to 30 degrees). ) to rotate the scrubbing head 210 to enter the inside of the ear canal. After entering, as shown in FIG. The wall, after moving by rotation through a certain angle (δ) to the adjacent track, through which it recedes to the outside of the external auditory canal to perform the wax-clearing action, all orbits of the head in the current depth of entry, and later as described All the tracks of the subsequent depth entered by the unit depth repeatedly perform the earwax removal action, thereby scraping the oily earwax to the outside.

The functions mentioned above are extremely important ergonomic functions, which can make the user feel no resistance and discomfort when using the product.

27 to 30 are drawings for explaining another example of a dry dedicated head that can be applied to embodiments of the present invention. FIG. 27 shows an example of an earwax removal device using a dry dedicated head. FIG. An enlarged view of the drying head, FIG. 29 is a sectional view of the drying head of FIG. 28 , and FIG. 30 is a modified example of the drying head of FIG. 27 . Compared with FIG. 28, the modified example of FIG. 30 is only slightly different in the shape of the hole 20a, and the rest are the same.

The method for the prevention of otitis externa of the existing otolaryngology department is to dry the ear with a hair dryer at about 30cm away from the ear, so it is extremely inconvenient to carry or use.

In addition, the air volume directly entering the ear canal is "area x wind speed" of the ear canal, so the area attached to the ear canal is greatly limited. Therefore, it is difficult to effectively and quickly dry the inside of the ear.

Since 5-10% of the world's population regularly suffers from otitis externa, there is a need for a simple, quick and effective method of drying the external ear canal after swimming, showering and washing the face.

Therefore, the present invention discloses a drying special tip (also called "drying tip") (refer to Fig. 27 to Fig. 30) for drying the external auditory canal, which can be installed on devices such as automatic air blowing, automatic ear dryers, etc. And use.

The dry special head 20 of Fig. 27 to Fig. 30 is made of biocompatible soft material (for example, rubber and silica gel) with a thin diameter d1 (about 2 mm to 3 mm), which can be comfortably and easily introduced into the ear.

The scrubbing head of the head 200 can be detached and the dedicated drying head 20 of FIGS. 27 to 30 can be installed in place of the scrubbing head.

In particular, the special drying head 20 in FIGS. 27 to 30 sprays wind from the outside of the ear like a hair dryer, so it can overcome the shortcoming that the wind cannot be blown into the external auditory canal effectively. That is, the drying dedicated head 20 of Fig. 27 to Fig. 30 is formed into a thin tube shape that is easy to enter the external auditory canal, and a diameter d2 (about 0.1 mm ~ 1.5 mm) and an angle (θ) between 45 ° and 90 ° are provided on the channel wall. There are a plurality of holes 20a, so that the wind is directly sprayed to the wall of the external auditory canal. Moreover, the pressure of the wind is directed towards the wall of the external auditory canal and the entrance of the external auditory canal, which can quickly remove the water droplets inside the external auditory canal to the outside of the ear, and at the same time effectively discharge the moisture to the outside.

Therefore, even if water flows into the ear after swimming and it is difficult to flow out, the water in the ear can be quickly removed, and at the same time, the pressure is not directly transmitted to the eardrum, so the user can dry the inside of the ear comfortably and safely.

The disadvantage of existing similar products is that since the wind is directly injected into the ear at the entrance of the external auditory canal, the entire external auditory canal is likely to form a closed space, and the resulting high pressure may be directly injected to the ear drum.

The special drying head 20 of Fig. 27 to Fig. 30 greatly makes up for these shortcomings and greatly improves the drying efficiency.

Fig. 31 is a system configuration diagram for explaining the functions of the earwax removal device of the present invention, a server, and a user terminal.

The system in FIG. 31 may include earwax removal devices 10 , 11 , a network 50 , a user terminal 60 and a server 70 .

The earwax removal devices 10 and 11 may include a mode selection unit 30 , a head drive unit 32 , a usage information registration unit 34 , a storage unit 36 , a communication unit 38 , a control unit 40 , a display unit 42 , and a user identification unit 800 . Although only one earwax removal device 10, 11 is shown in FIG. 31, it can be understood that there are actually a plurality of them.

As mentioned above, the user identification part 800 is configured to store and identify user's device usage information, may be a fingerprint recognition device (fingerprint recognition sensor), and may be disposed on the outer side of the main body part 400 . For example, the user identification part 800 may be provided at a position where the user's thumb touches when the user grasps the earwax removal device 10 , 11 .

The mode selection unit 30 can select an automatic mode or a manual mode.

Therefore, a button (not shown) may be provided on the main body 400 of the earwax removal device 10, 11 to select the automatic mode or the manual mode.

The above-mentioned remover 900 can be used in both automatic mode and manual mode.

In addition, a drying mode can be added to the mode selection unit 30 as needed, so that the drying head 20 shown in Fig. 27 to Fig. 30 can be used. Among them, preferably, the dedicated drying head 20 is used in the drying mode when the inside of the external auditory canal needs to be dried.

The head driving unit 32 can be connected to the pump 300 and the motor 500 to drive the head 200 .

The head driving section 32 can drive the head 200 according to the mode selected by the mode selection section 30 .

For example, when the automatic mode is selected, the head driving part 32 drives the above-mentioned linear guide, automatically slides the head 200 to the inside of the user's external auditory canal at a preset speed, and removes the earwax attached to the wall of the external auditory canal by using the scrubbing head and air discharge pressure. In other words, when the automatic mode is selected, as the scrubbing head 210 of the head 200 reaches the entrance side of the external auditory canal, the head driving part 32 rotates the head 200 at a predetermined angle (for example, 10 degrees to 30 degrees), thereby preventing the scrubbing head 210 from being stuck. It protrudes on the entrance side of the external auditory canal, and can automatically complete the subsequent earwax removal action. Wherein, automatically performing the earwax removal action (refer to FIG. 7 ) refers to repeatedly performing the following actions: the head (especially, the scrubbing head 210) enters the area divided into a plurality of tracks according to the preset unit depth through any track in the plurality of tracks. The wall of the external auditory canal, after moving to the adjacent track by a certain angle (δ) of rotation, recedes by the adjacent track towards the outside of the external auditory canal.

In addition, when the manual mode is selected, if the user directly operates the operation knob 601 by hand, the head driving unit 32 will slide the head 200 into the external auditory canal to remove the earwax attached to the wall of the external auditory canal. In other words, when the manual mode is selected, the head driving part 32 is activated to move and rotate the head 200 forward and backward according to the user's operation. The pump 300 advances inside the device 10, 11, so that the head 200 connected to the pump 300 advances to the outside through the collection hole 111 and is inserted into the inside of the external auditory canal. Back, so that the head 200 can be returned to its original position.

Of course, in the above-mentioned manual mode, the head driving unit 32 can automatically rotate the head 200 at a predetermined angle (for example, about 10° to 30°) when the scrubbing head 210 of the head 200 reaches the entrance side of the external auditory canal. This is to prevent the tip 250 of the scrubbing head 210 of the head 200 from being caught in the protruding part on the entrance side of the external auditory canal, but to enter the interior of the external auditory canal.

The usage information registration unit 34 stores the usage information of the device, such as the number of times the user has used the device, the usage time, etc. by the user identified by the user identification unit 800 , in the storage unit 36 .

The storage unit 36 can store the user's device usage information from the usage information registration unit 34 .

The communication unit 38 can transmit the user's device use information stored in the storage unit 36 to the server 70 via the network 50 . For this purpose, the communication unit 38 has a built-in wireless communication module such as Wi-Fi.

The control unit 40 controls the overall operation of the aforementioned earwax removal devices 10 and 11 .

The display section 42 may display a usage history analysis result (for example, calibration information) or a warning from the server 70 .

Network 50 can be realized by all types of wireless networks, such as mobile radiocommunication network (mobile radiocommunication network), satellite communication network, Bluetooth (Bluetooth), wireless broadband Internet (Wibro, Wireless Broadband Internet), high-speed downlink packet access (HSDPA , High Speed Downlink Packet Access), Wireless Fidelity (Wi-Fi), Long Term Evolution (LTE, Long Term Evolution), etc.

In addition, the network 50 may be implemented through a wired network, such as a local area network (LAN, Local Area Network), a wide area network (WAN, Wide Area Network), or a value-added network (VAN, Value Added Network).

The network 50 may be a mixed wired and wireless network as needed.

The user terminal 60 communicates with the server 70 through the network 50 .

The user terminal 60 may receive the usage history analysis result (such as calibration information) of the corresponding user from the server 70 through the network 50 and confirm it through the application program inside the terminal.

For example, the user terminal 60 can be realized by a portable terminal or a portable computer. Among them, the portable terminal is a wireless communication device that guarantees portability and mobility, including Personal Communication System (PCS, Personal Communication System), Global System for Mobile Communications (GSM, Global System for Mobile communications), Personal Digital Cellular (PDC, Personal Digital Cellular ), Personal Handyphone System (PHS, Personal Handyphone System), Personal Digital Assistant (PDA, Personal Digital Assistant), International Mobile Telecommunications (IMT, International Mobile Telecommunication)-2000, Code Division Multiple Access (CDMA, Code Division Multiple Access)-2000 , Wideband Code Division Multiple Access (W-CDMA, W-Code Division Multiple Access), Wireless Broadband Internet (Wibro, Wireless Broadband Internet) terminals and other handheld (Handheld) based wireless communication equipment. Laptops may include notebook computers, laptops.

And, the user terminal 60 can be various smart devices such as smart phones, smart notes, tablet computers, and wearable computers (wearable).

The server 70 may include a communication section 72 , a usage history management section 74 , a storage section 76 , a usage history analysis section 78 , and a control section 80 .

The communication unit 72 can communicate with the earwax removal devices 10 and 11 via the network 50 .

Furthermore, the communication unit 72 can communicate with the user terminal 60 via the network 50 .

The use history management unit 74 can manage the device use information received through the communication unit 72 from one or more users of the earwax removal devices 10 and 11 for each user's use history. That is, the use history management unit 74 can store the use history of each user in the storage unit 76 .

The storage section 76 stores the usage history of each user through the usage history management section 74 .

In other words, the storage unit 76 individually stores the usage history of each user, such as the usage times and usage time of the device, for each user.

The use history analyzing part 78 can analyze each user's optimal rotation speed (that is, the rotation speed of the scrubbing head), wind force (that is, the air blowing intensity of the drying head) based on the use history of each user stored in the storage part 76. ), etc., and output the corresponding calibration information.

Wherein, the calibration information can be transmitted to the corresponding user's earwax removal device 10 , 11 or the corresponding user's terminal 60 through the network 50 .

The above calibration information can be said to use historical analysis results.

Of course, the use history analysis section 78 can analyze the user's use history and give appropriate warnings. Wherein, the above-mentioned warning is a warning for users who frequently experience cerumen embolism for the purpose of preventing cerumen embolism. The user's terminal 60 transmits prompt information.

The control unit 80 can control the overall operation of the server 70 described above.

Fig. 32 is a diagram for explaining the necessity of waterproofing and noise reduction of the earwax removal device, Fig. 33 is a diagram for explaining important parts of the earwax removal device according to the fifth embodiment of the present invention, and Fig. 34 is for explanation When the scrub head retreats backward in Fig. 33, the accompanying drawings of the deformation of the waterproof and sound-proof sheet, Fig. 35 is a drawing for explaining the deformation of the waterproof and sound-proof sheet when the scrub head retreats backward in Fig. 33, Fig. 36 And Fig. 37 is a drawing for explaining the rotation of the waterproof and soundproof sheet shown in Fig. 33.

For an earwax removal device having the purpose of removing earwax and drying the external auditory canal, the daily waterproof performance of the earwax removal device is a very important performance in commercialization.

Also, conventional earwax removal devices can cause noise to the ears of noise-sensitive users. Noise from motors and the like inside the earwax removal device can cause a sense of resistance to the user. However, due to the nature of its use, it cannot be tolerated.

Due to the nature of the earwax removal device, the tip for removal (e.g., the tip of the scrub head) and the tip for drying (e.g., the dry tip) must enter the interior of the ear canal, so for the linear and rotational movement of the tip, the tip is Designed to move freely without contact with the wax removal device.

Thus, as shown in FIG. 32 , there is a gap separating a distance d3 between the earwax removal device 10 , 11 and the tip (eg, the tip of a scrub head) 201 . Therefore, the operating noise of the earwax removal devices 10, 11 is directly applied to the ear through the slit, and water flows into the inside of the earwax removal devices 10, 11 through the slit.

Therefore, the earwax removal device according to the fifth embodiment of the present invention has a structure that allows the tip (for example, the tip of a scrub head, a dry head) to move freely in a straight line and in rotation while also being noise-blocking and waterproof.

As shown in FIG. 33 , the earwax removal device of the fifth embodiment of the present invention may include a waterproof and soundproof sheet 30 integrally formed with a moving axis 32 between the head and the pump 300 .

That is, the head (including the scrubbing head 210) and the pump 300 are connected to each other through the movement shaft 32, and the waterproof and soundproof sheet 30 is integrally formed with the movement shaft 32 between the head and the pump 300, and is perpendicular to the movement shaft 32. direction formed.

In other words, the waterproof and soundproof sheet 30 is disposed inside the main body part 400, and is formed at the rear end of the remover 900 in a direction perpendicular to the movement axis 32 to be separated from the remover 900. The central part of the waterproof and soundproof sheet 30 is in contact with the movement The shaft 32 is integrally formed.

Moreover, the edge of the waterproof and sound-insulating sheet 30 is combined with the inner surface of the main body 400 . For example, the edge of the waterproof and sound-insulating sheet 30 may be bonded to the inner surface of the main body 400 to be sealed. As another example, a ring-wrapped seal (not shown) is formed on the inner surface of the main body 400 , and the edge of the waterproof and sound-insulating sheet 30 is bonded to the seal to enable sealing.

Those skilled in the art can fully understand the sealing structure by the bonding process and the sealing structure using the sealing material described above, even if they are not shown in the drawings.

Therefore, the inside and outside of the earwax removal devices 10 and 11 can be physically completely isolated with the waterproof and soundproof sheet 30 as the boundary.

In addition to the above examples, there may be various combinations of the edge of the waterproof and sound-insulating sheet 30 and the inner surface of the main body 400 .

The waterproof and sound-insulating sheet 30 may be a thin sheet formed of polyethylene (PE), polypropylene (PP), low-density polyethylene (LEPE) and the like with a thickness of approximately 0.01 mm to 0.5 mm.

In addition, the waterproof and sound-insulating sheet 30 may be formed of a soft material (soft thinsheet, silica gel, rubber, etc.) sheet with a thickness of about 0.01mm˜0.5mm.

The waterproof and sound-proof sheet 30 can be stretched or deformed without great resistance when the scrubbing head 210 moves in a two-way linear motion and rotates (within 360 degrees).

For example, when the scrubbing head 210 moves forward (such as when entering the external auditory canal), the central part of the waterproof and soundproof sheet 30 moves forward along the movement axis 32, so the waterproof and soundproof sheet 30 can be stretched as shown in FIG. 34 .

On the contrary, when the scrub head 210 moves backward (for example, when withdrawing from the external auditory canal), the central part of the waterproof and soundproof sheet 30 moves backward along the movement axis 32, so the waterproof and soundproof sheet 30 can be stretched as shown in Figure 35 .

In addition, when the motion shaft 32 is rotated in order to rotate the scrubbing head 210, the waterproof and sound-proof sheet 30 rotates in the same direction as the rotation direction of the motion shaft 32, so the waterproof and sound-proof sheet 30 is rotated and folded as shown in FIGS. 36 and 37 . .
