Description

  The present invention relates to an attachment for a personal and portable air conditioner and a portable air conditioner.

  In recent years, with the increase of allergic individuals such as hay fever, an air purifier has been installed in the room, and this air purifier removes suspended matters such as pollen, dust, pathogens, and other suspended particulates to purify the air. It is widely done.

  On the other hand, since it is difficult to carry and install such air purifiers in public places such as when going out or at work, each person wears a mask made of gauze or non-woven fabric and floats. To prevent the body from entering the body. However, when using such a mask, every time the user breathes, the inside of the mask becomes negative pressure or positive pressure, so that floating substances are generated from the gap formed between the face and the mask. In the present situation, outside air containing air is often mixed, and the effect of removing suspended matters by the mask is not so much.

  Therefore, there is a demand for a portable air purifier that can be used while traveling such as going out, or can be used personally in the workplace. Examples of such portable air cleaning devices include those described in Patent Documents 1 and 2.

  Patent Literature 1 includes a portable air purification device for personal use, a mask covering the nose and mouth, and optionally the eyes, and a flexible and elastic air duct connecting the air purification device and the mask. A portable air purifying device is described.

  Further, Patent Document 2 describes a wearable air purification device that covers a face with a transparent plastic plate and blows purified air into a space generated in a gap with the face. The plastic plate is formed so as to cover the face from the forehead to the nose, and the purified air is sucked between the plastic plate and the face from the forehead to the nose side. It is described that it is possible to prevent the inflow of contaminated outside air by creating a higher pressure field than outside air.

Japanese National Patent Publication No. 8-503622 JP 2001-61979 A

The portable air purification device described in Patent Document 1 is provided with a mask that integrally covers the nose and the mouth and forcibly blows the air purified by the air purification device. In contrast, it is thought that the entry of floating substances into the body can be prevented with little external air contamination.
However, since the portable air purification device of Patent Document 1 covers the nose and mouth integrally with a mask, it not only gives the user a feeling of breath and pressure, but also makes it difficult to talk and eat. It is difficult to use on a daily basis.

  On the other hand, the wearable air purification device described in Patent Document 2 is open around the mouth, so it seems that problems such as difficulty in breathing, difficulty in conversation, and meals can be solved. However, the plastic plate is formed only to cover the user's nose, and the outside air containing floating substances is likely to be mixed due to the suction force of the nose by breathing. Further, since the purified air is sucked from the forehead toward the nose, it is blown out through the periphery of the nose and it is difficult to suck the purified air from the nostrils. Guessed.

  Therefore, in view of the above problems, the present invention prevents the air containing external floating substances from being drawn and sucked, and does not cause a feeling of pressure or breathlessness, which may hinder conversations and meals even during use. An object of the present invention is to provide an attachment for a portable air conditioner and a portable air conditioner.

  The attachment of the portable air conditioner of the present invention includes a vent pipe that allows purified air to flow in a direction substantially perpendicular to the nose muscles below the nostril, and the vent pipe is formed in a portion where the nostril is located. And having an opening.

  In the present invention, the air purified by an air cleaner or the like flows in a direction substantially perpendicular to the nasal muscles below the nostrils because of the provision of the vent pipe. Here, when the user breathes through the nose, a suction force is generated from the vent tube toward the nostril due to the breathing, and the purified air is drawn from the opening of the vent tube without entraining air containing external floating substances. Can be aspirated.

  Here, it is desirable that the air flowing through the ventilation pipe has a Reynolds number of 1000 or more and 3000 or less, more preferably 1400 or more and 2300 or less. When the Reynolds number of the air flowing through the vent pipe is 1000 or more and 3000 or less, the air flow in the vent pipe can be stabilized, and the pressure in the vent pipe is almost the same as or slightly positive. Since the air purified from the opening of the vent pipe slightly overflows, it is possible to prevent unpurified air from being mixed around the nostril. Thereby, when the user breathes through the nose, it is possible to further prevent the air containing the external floating matter from being caught and sucked. Further, by making the air flowing through the vent pipe stable, it is possible to make the air flow to the extent that it gently flows under the user's nose.

  If the Reynolds number of the air flowing through the ventilation pipe is less than 1000, there is a possibility that air containing external floating substances flows into the ventilation pipe from the opening. On the other hand, if the Reynolds number is greater than 3000, the air flow in the vent pipe is disturbed, which causes discomfort to the user.

  It is more preferable that the Reynolds number is 1400 or more and 2300 or less, whereby the air flowing through the vent pipe can be made into a laminar flow, and the air flow that does not cause discomfort or discomfort to the user. It can be.

  Further, it is desirable that the ventilation tube covers the lower part of the nose including the nostril. By covering the lower part of the nose, even if the airflow around the ventilation pipe is disturbed by disturbances such as strong winds and gusts, it is possible to completely prevent the air containing the external floating material from being sucked in.

  It can be set as the portable air conditioner provided with the attachment of the said portable air conditioner, and the portable air cleaner. Thereby, it can be set as the portable air conditioner which can be used during movements such as going out, personally used in the workplace, or used on a daily basis.

According to the present invention, the vent pipe allows the purified air to flow in a direction substantially perpendicular to the nose muscles below the nostrils, so that outside unpurified air is not involved from the nostrils. Purified air can be aspirated, and pollen, dust, pathogenic bacteria, and other suspended fine particles can be prevented from entering the body.
In addition, since the purified air can be sucked without integrally covering the nose and mouth, there is no feeling of pressure and breathlessness, and conversation and meals can be performed freely during use.

  FIG. 1 is a diagram showing a state in which a portable air conditioner according to an embodiment of the present invention is mounted. 2A and 2B are diagrams showing an air cleaner of the portable air conditioner of the present embodiment, where FIG. 2A is a perspective view and FIG. 2B is an exploded perspective view. FIG. 3 is a perspective view of the attachment of the portable air conditioner of the present embodiment, where (a) is the front side and (b) is the back side.

  As shown in FIG. 1, the portable air conditioner 1 according to the present embodiment is mounted on an air purifier 10 that can be carried by hanging from a neck or by wearing it on a belt, and on the face of a user. And an attachment 20 that allows the user to suck the air purified by the air cleaner 10.

  The air purifier 10 is an air purifier that is miniaturized to a portable size and reduced in weight. As shown in FIG. 2, the air purifier 10 includes a small battery 12, a fan unit 13, and a filter 14 in a main body cover 11.

  The small battery 12 is a drive source that drives the fan unit 13 and is rechargeable. It is also possible to attach a small battery as an accessory. The fan unit 13 is formed in a thin rectangular parallelepiped, and includes a power switch (not shown), an air volume adjusting volume 13a, and an attachment port 13b for connecting an air supply pipe 30 described later.

  The filter 14 includes a main filter 14a and a prefilter 14b made of an activated carbon filter, a high performance filter, or the like. The pre-filter 14b removes relatively large suspended matters floating in the air, and the main filter 14a removes pollen, fine dust, pathogenic bacteria, and the like. Depending on the type of suspended matter to be removed, the main filter 14a is different from the above-mentioned activated carbon filter and high-performance filter in that it has different additional functions such as an artificial nasal filter used in a ventilator and a filter used in an antibacterial mask. Any type or plural types can be selected and used.

  As shown in FIG. 3, the attachment 20 includes a vent pipe 21 that is gently curved as a whole along the face, and a locking tool 22 for mounting the vent pipe 21 on the face.

The vent pipe 21 is a tubular body having a diameter, that is, an area of a cross section in the direction perpendicular to the axis of about 5.0 cm ² , and crosses the face from one cheek side to the other cheek side, and has a nostril. It is formed to cover the lower part of the nose. The vent pipe 21 may be formed of any material having water resistance enough to prevent deformation or tearing due to water vapor contained in the air, and plastic, aluminum, or water-resistant treatment is applied. Although cardboard or the like can be used, it is more desirable for the user to feel good.

  The vent tube 21 is a portion where a nostril is located, and an opening 23 into which a lower portion of the nose can be inserted is formed. A cushion member made of a material such as rubber or sponge that prevents the inflow and leakage of air and reduces friction between the edge of the opening 23 and the nose muscles at the edge of the opening 23 that touches the nose muscles. 23a is attached.

  An inlet 24 for taking in air purified by the air purifier 10 through the air pipe 30 is formed at one end of the vent pipe 21, and the vent pipe 21 is formed at the other end of the vent pipe 21. A discharge port 25 is formed through which air that has passed through is discharged.

  The locking tool 22 may be anything as long as it can be locked to the ear, and for example, a rubber or string having a ring shape can be used. In addition, it is desirable that the locking tool 22 can be appropriately adjusted in length and size by the user so that the ventilation pipe 21 can be mounted along the face without any gap.

  The air supply tube 30 is a flexible rubber tube, a tube made of vinyl chloride, an olefin-based elastomer, or the like, or a bellows-like plastic tube, and blows air purified by the air purifier 10 to the attachment 20. It is. As described above, one end of the air supply pipe 30 is connected to the attachment port 13 b of the air cleaner 10, and the other end is connected to the introduction port 24 of the attachment 20. The length of the air supply pipe 30 can be appropriately adjusted according to the case where the air purifier 10 is hung from the neck or attached to the belt. In addition, the air pipe 30 is used by being lightly fixed to several clothes with pins or the like so as not to be caught by surrounding objects when worn.

Next, the use state of the portable air conditioner in the present embodiment will be described.
First, the air purifier 10 is hung from the neck or attached to the belt, and the engaging tool 22 of the attachment 20 is hooked on the ear and attached. Then, both ends of the air supply pipe 30 are connected to the air cleaner 10 and the attachment 20, respectively.

  The power of the air cleaner 10 is turned on, and the air volume adjustment volume 13a is adjusted so that the amount of air fed into the vent pipe 21 is 25 to 40 L / min. As a result, the air purified by the air cleaner 10 passes through the air supply tube 30 and is supplied from the introduction port 24 of the attachment 20 into the ventilation tube 21, and becomes substantially perpendicular to the nose muscles below the nostrils. It flows in the direction and is discharged from the discharge port 25. When the user breathes through the nose, the purified air is sucked from the nose by the suction force generated in the direction from the vent tube toward the nostril.

  Thus, in the present embodiment, the use of the attachment 20 allows the purified air to flow at a substantially right angle below the nostrils with respect to the suction force by respiration. Only purified air can be aspirated without entraining air containing suspended matter.

In the present embodiment, the cross-sectional area of the vent pipe 21 in the axial vertical direction is 5.0 cm ² , and the air supply rate is 25 to 40 L / min, which is slightly higher than the respiration rate of adults. The air in the trachea 21 has a stable flow with a Reynolds number of 1400 to 2300, and is almost in the state of the atmospheric pressure or slightly positive in the vent pipe 21. That is, the air purified from the opening 23 of the vent pipe 21 slightly overflows, and even if a gap is generated between the user's face and the opening 23 of the vent pipe 21, the air is difficult to flow in. It has become. As a result, it is possible to further prevent the outside air containing floating substances from entering the ventilation pipe 21, and when the user breathes through the nose, the unpurified air outside the ventilation pipe 21 is entrained. Aspiration can be completely prevented.

  Further, in the present embodiment, it is possible to insert the lower part of the nose into the opening 23 so that the ventilation tube 21 covers the lower part of the nose, that is, the opening 23 has air. Since the cushion member 23a for preventing the inflow and leakage of the air is attached, it is possible to further prevent the air including the floating matter around the nose from being caught. Further, even if the airflow around the ventilation pipe is disturbed by disturbance such as strong wind or gust wind, it is possible to prevent the air containing floating matter from flowing into the ventilation pipe 21.

  As described above, in the present embodiment, the purified air can be sucked from the nostrils without entraining the external unpurified air by the attachment 20 of the portable air conditioner 1, so that pollen and dust In addition, pathogenic bacteria and other suspended fine particles can be prevented from entering the body. Further, since the purified air can be sucked without integrally covering the nose and the mouth, there is no feeling of pressure and breathlessness, and conversation and meals can be performed freely during use.

  In addition, according to the present embodiment, the purified air flows in a direction substantially perpendicular to the direction of the nasal nasal cavity, so that a large amount of the purified air is directed directly toward the nasal cavity. Since it does not flow, the mucous membrane in the nasal cavity is not excessively dried, and the user does not feel uncomfortable.

The shape of the vent pipe 21 and the cross section in the direction perpendicular to the axis are not limited to the above-described embodiments, and are large enough not to interfere with meals and conversations or cause a sense of incongruity in design when worn by the user. However, in order to ensure that the air flow rate is slightly higher than the adult's breathing volume, the air flow is such that it flows gently under the user's nose. It is desirable to secure at least about 1.8 cm ^{2 of the} cross-sectional area in the direction perpendicular to the axis. In addition, the shape of the cross section in the direction perpendicular to the axis of the vent pipe 21 may be any shape such as a perfect circle, an ellipse, or a substantially rectangular shape curved in accordance with the shape of the face. In addition, when making into a perfect circle, it is desirable to form so that the internal diameter of a cross section perpendicular to an axis may be at least about 15 mm.

  In the present embodiment, the locking member 22 of the attachment 20 is a rubber or string ring-shaped one, but is not limited thereto, and may be a glasses-type locking member 42 as shown in FIG. Good. The end 42 a of the locking tool 42 on the side where the introduction port 24 of the vent pipe 21 is provided in the glasses-type locking tool 42 is connected to the introduction port 24, and the other end of the locking tool 42. The air supply pipe 30 can be connected to the part 42b. Thereby, the air pipe 30 is located on the back side of the ear, and uncomfortable feeling and annoyance caused by the air pipe 30 touching the face can be reduced.

  In addition, as shown in FIG. 5, in consideration of the design at the time of attachment, a nose fold type attachment in which the portion corresponding to the lower part of the nose of the vent pipe 51 is colored and the other portion is formed of a transparent member. It can also be 50.

In addition, the air cleaner 10 of this Embodiment is not restricted to the said embodiment, Arbitrary portable air cleaners can be used. Moreover, it can also be set as the structure provided with the heating apparatus, the humidity control apparatus, and the negative ion generator in the air cleaner 10. FIG. If equipped with a warming device and humidity control device, it is possible to supply warm air containing a certain amount of moisture to the user even in winter, and to make it a portable air conditioner that can prevent stuffy nose and dryness be able to.
Moreover, if a negative ion generator is provided, the air containing a negative ion can be supplied to a user, and it can be made the state in which a cell can absorb oxygen and a nutrient more easily. Thereby, if the portable air conditioner of this Embodiment is used, while the physiological effect of a human body can be made smooth, the natural healing power which a person originally has can also be raised.

  In addition, if the user has a cold while inhaling the purified air, or if the user does not want to exhale his / her exhalation into the room, a newly prepared outlet 25 of the vent pipe 21 is available. If an exhaust pipe is connected to an air intake port (not shown) of one air purifier 10, the exhaled air is discharged after passing through the air purifier 10 once. It can also be discharged in a state of being filtered and cleaned. In this case, the connection portion between the exhaust pipe and the discharge port 25 of the vent pipe 21 is preferably provided with a slight gap so that a small amount of outside air is taken into the exhaust pipe together with exhalation. Thereby, exhaled air can be exhausted to the air purifier 10 without disturbing the air flow in the vent pipe 21.

  Further, if the air is in a clean space (for example, a clean room), the end of the air supply pipe 30 attached to the attachment port 13b of the air cleaner 10 is connected to the air intake port (not shown) of the air cleaner 10. It may be used by connecting to In this case, the purified air in the space can be taken in from the discharge port 25 side and breathed, and the exhaled air from the nose can be sent to the air purifier 10 and discharged in a clean state. Thereby, it can prevent contaminating the air in space by a user's expiration.
