Detailed ways

The vacuum cleaner nozzle and the vacuum appliance involved in the present invention will be described in detail below with reference to the accompanying drawings.

＜Example 1＞

In the first embodiment, the vacuum cleaner includes: a vacuum cleaner nozzle 10 , an air duct connection part and a dust suction part. The suction nozzle 10 of the vacuum cleaner is matched with the connecting part of the air duct, and is used for cleaning the hair on the pet's body and waiting to be cleaned. The dust collection part provides suction force for the vacuum cleaner nozzle 10, absorbs the hair, dust, etc. cleaned by the vacuum cleaner nozzle 10, and serves as a dust collection mechanism of the vacuum cleaner to store these objects to be cleaned.

As shown in Figures 1, 2, 3, 4, 5, 6, 7, and 8, the vacuum cleaner nozzle 10 is used to comb and clean pet hair, and it includes: an upper cover portion 21, a driving member 12, a middle cover 22, and a comb Component 13, lower cover part 23 (see Figure 3). Another combing opening 71 is located under the front of the body formed by the upper cover 21 , the middle cover 22 and the lower cover 23 , and the damper 70 is located behind the combing opening 71 (see FIG. 2 ).

The comb member 13 comprises a rotating body and at least one comb tooth portion formed on the rotating body, the comb tooth portion contains a base 28 and a plurality of comb teeth 29, the comb teeth 29 are fixed on the base 28, and the plurality of comb teeth The arrangement direction of the teeth 29 is consistent with the length direction of the damper 70 . In the first embodiment, the rotating body includes a base post 59, a base concave hole 60 and a connecting plate connecting the base post 59 and the base concave hole 60, and the rotation of the rotating body can drive the base 28 to rotate. The cross-sectional shape of the comb teeth 29 is straight, and the extension direction is perpendicular to the axial direction of the rotating body, and is arranged on the surface of the base 28 along a direction parallel to the axial direction of the rotating body. The combing member 13 has two positions: a combing state and a storage state. In the combing state (that is, when the comb teeth 29 are in the combing position), the comb teeth 29 protrude from the combing opening 71 for combing pet hair. In the storage state (that is, when the comb teeth 29 are in the cleaning position), the comb teeth 29 point to the damper 70 and can stop in front of the damper 70 (see FIG. 3 ).

The rear of the lower cover part 23 has an air outlet 79 and the hollow handle 50 , and the air outlet 79 is also the air inlet of the hollow handle 50 . There is an interface 80 on the rear of the hollow handle 50 for connecting to the air duct connecting part of the vacuum cleaner (see FIG. 3 ).

The upper cover portion 21 also has an air leak window 52, which is positioned on the outside of the air door 70, and is respectively located on the upper and lower sides of the rotating body of the carding member 13 with the carding opening 71, so as to ensure that sufficient air volume enters the air door 70 during the carding state to prevent carding. During the process, the combing opening 71 is blocked by the pet's body and hair so that the suction force of the dust-absorbing part of the vacuum cleaner is all applied to the pet's body, thereby causing discomfort to the pet. Simultaneously ensure that in the storage state, the up and down directions of the comb teeth 29 have suction airflow entering the damper 70, and the upper and lower sides of the comb teeth 29 are forced at the same time, which is easier to strip the hair from the comb teeth. The upper cover part 21 is also provided with a buckle hole 53 for engaging with the buckle 66 of the lower cover part 23, so that the upper cover part 21 and the lower cover part 23 can be reliably matched to form a cavity so as to accommodate other parts and mechanisms (see image 3).

The middle cover 22 is provided with four buckles 62 for pressing the connecting rod 24 to ensure that the connecting rod 24 can move forward and backward according to the path set by the buckles 62 and the guide ribs 81 without warping or twisting. The middle cover 22 is also provided with a spring stopper 63 for fixing the front end of the spring 25 . The middle cover 22 is also provided with an upper damper baffle 61 , opposite to the lower damper 68 on the lower cover 23 , forming a damper 70 located between the carding opening 71 and the hollow handle 50 (see FIGS. 2 and 3 ).

Both the height H1 of the damper upper baffle 61 and the height H2 of the damper lower baffle 68 can be zero (see FIG. 7(A)). In this embodiment, their heights are not zero, so that the cross-sectional area of the damper 70 is smaller than the front exterior ventilation cross-sectional area. The upper cover part 21 and the lower cover part 23 are all straight shapes in this embodiment, the upper cover part 21 can be made into an upwardly convex arc shape, and the lower cover part 23 can also be made into a downwardly convex circle. arc. The length E of the damper 70 is not less than the length A of the distribution range of the comb teeth 29 on the base 28 (see FIG. 5 ). The optimum solution for the cross-sectional area of the damper 70 is to be smaller than the front and rear ventilation cross-sectional areas of the damper 70 respectively, that is, the damper is formed by shrinking the airflow channel.

The lower cover 23 is provided with an air outlet 79 and a hollow handle 50 , and the user can hold the outer wall of the hollow handle 50 to use the pet groomer. The outer wall of the hollow handle 50 can be smooth, also can have stripes, or be made into other rough surfaces, and can also be coated with soft glue to prevent slipping. The lower cover part 23 is also provided with an air duct 72 located between the damper 70 and the hollow handle 50 . As shown in the area surrounded by the dotted line and the inner wall of the lower cover part 23 in Figure 5, in the first embodiment, the air guide duct 72 has a leading area 73 communicated with the air door 70 and communicated with the hollow handle 50 The trailing area 74.

The position and size relationship of the area 73 is set in such a way that the extension direction of any comb tooth 29 pointing to the inside of the damper 70 is parallel or approximately parallel to the direction of the suction airflow passing through the comb tooth 29 (see FIG. 7(B)). That is, the extension direction of any comb teeth 29 pointing to the inside of the damper 70 is parallel to the cross-section of the leading area 73 of the air guide duct 72 in the direction of the inhaled airflow.

The optimal solution of the left and right side walls of the leading area 73 is linear (that is, the leading area 73 has a rectangular cross-section in the direction from the damper 70 to the hollow handle 50), and the optimal shape of the rear guiding area 74 is a circular arc. The forms converge toward the air outlet 79 (as shown in Figure 5). On the premise that the length is greater than the length of the damper 70, the shape of the leading area 73 can also be other shapes. The depth of the leading area 73 and the rear guiding area 74 along the suction airflow direction should be deep enough to ensure that the suction airflow direction flowing through the left and right edge comb teeth 29 is parallel or approximately parallel to the extension direction of the comb teeth 29. After satisfying the depth requirement, the trailing guide area 74 can also adopt other shapes.

The lower cover 23 is also provided with buckles 66, which engage with the buckle holes 53 of the upper cover 21, so that the upper cover 21 and the lower cover 23 can be reliably matched to accommodate other parts and mechanisms.

The lower cover part 23 is also provided with a round hole 67 for placing the transmission ring 27 . The inner hole 58 of the drive ring 27 is cylindrical.

Action description:

In the first embodiment, the vacuum cleaner suction nozzle 10 is first connected to the air duct connecting portion of the vacuum cleaner to ensure that the comb teeth 29 protrude outward from the combing opening 71, and the power of the vacuum cleaner is connected, and the inhaled airflow passes through the combing opening 71 and the air leakage window 52 enter the damper, pass through the leading area 73 and the rear guiding area 74 of the air duct 72, and then flow to the dust collection chamber of the dust suction part through the air outlet 79 and the hollow handle 50. At this point the vacuum cleaner nozzle 10 can be used to groom the pet.

After a certain amount of hair has accumulated on the comb teeth 29 , the user can push the push button 20 forward with the thumb, and hold the outer wall of the hollow handle 50 with the other four fingers. The push button 20 drives the connecting rod 24 forward. During the forward process of the connecting rod 24, while compressing the spring 25, the rack 54 on the connecting rod 24 pushes the driven tooth 56 on the gear 26, so that the gear 26 rotates forward and drives the transmission. The ring 27 rotates forward, and the transmission ring 27 drives the combing member 12 to turn to the damper 70 from the combing state in the form of a single pendulum and can be parked in front of the damper 70 to enter the storage state, and the comb teeth 29 point to the inside of the damper 70 (see Fig. 7A, Fig. 7B ), and at the same time make the extension direction of the comb teeth 29 parallel to, or approximately parallel to, the section of the leading area 73 of the air guide duct 72 in the direction of the suction airflow. At this time, the combing opening 71 and the air leakage window 52 transmit the airflow from the upper and lower directions of the comb teeth 29 to the damper 70 respectively. The frictional force between the hair and the comb teeth 29 can make the hair break away from the comb teeth 29 and enter the damper 70 .

In order to allow the inhaled airflow to take away the hair more effectively, all places on the comb member 12 that touch the hair should be smooth and rounded to prevent the hair from being caught.

After the thumb releases the push button 20, the spring 25 resets from the deeply compressed state, pushes the connecting rod 24 back to reset, the rack 54 on the connecting rod 24 drives the driven tooth 56 to rotate backward, and then drives the combing member 13 to swing through the drive ring 27 Reset, so that the comb teeth 29 get back to the combing state.

There is a tool slot 78 on the outside of the end cover 30, and the end cover 30 can be twisted with a coin-like metal sheet or plastic sheet to loosen it from the locking hole 69 and take it out, and then the combing member 13 can be taken out successively for maintenance or replacement .

The vacuum cleaner nozzle 10 can be directly connected with the hose of the vacuum cleaner (that is, the air duct connection part), or can be connected with the vacuum cleaner hose through an adapter tube or an adapter hose. The interface of the transfer hard pipe or the transfer hose can be made into different calibers, so as to cooperate with the vacuum cleaner hoses of different calibers.

In the above embodiment, there is only one row of comb teeth. When the comb teeth point to the damper, the comb members can be fixed with hooks or stoppers or other mechanisms, so that the comb teeth can stay in the storage state for a long time, so as to reduce the shape of the vacuum cleaner nozzle. The size is convenient for packaging and transportation, and it also avoids the exposure of the comb teeth to prevent accidental damage.

The driving member may also include a coil spring (coil spring) and a connecting rod instead of a gear and a rack, and the central axis of the coil spring (coil spring) is parallel to the axial direction of the rotating body of the carding member. The user uses the connecting rod to drive the comb teeth in the combing member to change from the combing state to the storage state in the form of a single pendulum and can stop in the storage state and point to the damper. During the swing process, the coil spring (coil spring) is deformed by force and the connecting rod is loosened. Afterwards, the elastic force of the coil spring (helical spring) reset will drive the combing member to swing back to the combing state.

Function and effect of embodiment one

According to the vacuum cleaner suction nozzle and vacuum cleaner described in Embodiment 1, because the extension direction of the comb teeth is perpendicular to the axial direction of the rotating body, and the length direction of the damper is parallel to the axial direction of the rotating body, the length of the damper is not less than one row The length of the distribution range of the comb teeth on the base. At the same time, the air induction channel has a leading area connected with the damper. Therefore, whether it flows through the comb teeth located in the middle of the base or the comb teeth located at the left and right edges, the airflow direction is parallel or approximately parallel to the extension direction of the comb teeth, so that any comb teeth in the storage state The hair entangled on the top can be sucked into the damper with the wind.

In addition, because there is a tool slot on the outside of the end cap, you can insert a metal sheet or plastic sheet similar to a coin into the tool slot to twist the end cap, loosen the end cap and the locking hole and take it out, and then you can take out the carding in turn. components, so it is very convenient for users to maintain and replace the combing components.

In addition, the suction nozzle of the vacuum cleaner in this embodiment adopts a single pendulum structure, which not only ensures that the user can realize the functions of combing and absorbing hair with one hand, but also simplifies the driving mechanism, reduces the cost of materials, makes it easier to popularize, and reduces The size and weight of the product are improved, and professional users will not feel tired after long-term continuous use, making the product more portable and reliable.

The air guide duct 160 includes a front guide area 160a and a rear guide area 160b, and the air outlet 161 of the rear guide area 160b is the air intake of the hollow handle 150. mouth. The air outlet 162 of the hollow handle 150 is also an interface matched with the vacuum cleaner.

The combing member 101 includes a rotating body 167 and two comb teeth, one of which is at the combing position and the other is at the cleaning position. In this embodiment, an angle of about 98° is formed between the two comb teeth. One comb tooth part includes: base 112 and comb teeth 113a, and the other comb tooth part includes: base 112 and comb teeth 113b. The left side of the rotating body 167 is provided with a limiting rib 157b, a base rotating shaft 158b, and a positioning rib 159b (see FIG. 12 ), respectively matching with corresponding slots on the left bracket 164 . The right side of the rotating body 167 is provided with a limiting rib 157a, a base rotating shaft 158a, and a positioning rib 159a (see FIG. 13 ), respectively matching with corresponding slots on the right bracket 163 . The rib shafts on the left and right sides of the rotating body and the corresponding slots on the inner sides of the left and right brackets constitute a rotating member.

As shown in Figures 12 and 14, in the second embodiment, the left bracket 164 and the right bracket 163 respectively extend toward the outside of the damper 152 along the left and right sides of the leading area 160a, and are used as two mounting arms for rotatably installing Rotating body 167.

The form of the comb teeth 113a and 113b can be various common forms such as needle comb and row comb, and the material can be plastic or metal, etc., and the size can be various common comb teeth sizes. The optimum solutions of the comb teeth 113a and 113b are completely the same, and different forms can also be adopted respectively.

Both the left bracket 164 and the right bracket 163 are made of materials with relatively good elasticity. In a free state, the left bracket 164 and the right bracket 163 can move about 3 millimeters in a direction away from each other. The length of the left and right ends of the carding member 101 is about 2 millimeters larger than the distance between the left support 164 and the right support 163 in the free state. Because of the elasticity of the material, the left bracket 164 and the right bracket 163 are able to clamp the combing member 101 . As long as the left bracket 164 or the right bracket 163 is moved outward, the combing member 101 can be taken out for maintenance or replacement.

Action description:

In the second embodiment, the vacuum cleaner nozzle 100 is first connected with the vacuum cleaner to ensure that the comb teeth 113a protrude outwards, and at this time another set of comb teeth 113b points to the inside of the damper 152 (see FIG. 16A ). At this time, the positioning rib 159a (see FIG. 13 ) on the right side of the rotating body 167 engages with the positioning groove 153a (see FIG. 12 ) of the right bracket 163 . The rotating shaft hole 154a is engaged with the base rotating shaft 158a, so that the combing member 101 can rotate around the base rotating shaft 158a. The limiting rib 157a is engaged with the limiting groove 155a, and can only move in the limiting groove 155a. The partial enlarged view of the positioning rib 159a and the limiting rib 157a is shown in FIG. 12 . The corresponding relationship between the left side of the rotating body 167 and the parts on the left bracket 164 is also the same.

Turn on the power of the vacuum cleaner, the inhaled airflow enters the damper 152 through the carding opening 165 and the air leakage window 166, passes through the leading area 160a and the rear guiding area 160b of the air duct 160, and then flows to the dust chamber of the vacuum cleaner through the air outlet 161 and the hollow handle 150. Now you can start grooming your pet with the vacuum nozzle.

After a certain amount of hair has accumulated on the comb teeth 113a, the user holds the hollow handle 150 tightly, and gently pushes the comb teeth 113a towards the pet's body. Rib 159a is transferred in the positioning groove 156a from the positioning groove 153a of the right bracket 163, and the rotating shaft hole 154a still cooperates with the base rotating shaft 158a, and the limiting rib 157a turns to a new angle inside the limiting groove 155a, assisting the positioning rib 159a in Stand firmly in the new positioning slot 156a. The comb teeth 113a with hair turn to the damper 152 and point to the inside of the damper 152 along with the movement of the positioning rib 159a, and the comb teeth 113b then rotate upwards from the front of the damper 152 and stretch out from the air leakage window 166 upwards. At this time, the inhaled airflow flows from the combing opening 165 and the air leakage window 166 to the damper 152 at the same time, and the hair accumulated on the comb teeth 113a is pushed towards the damper, and then enters the hollow handle 150 along the air duct 160. And then fly to the dust chamber of the vacuum cleaner (see Figure 13).

Then, the user holds the hollow handle 150 and turns the suction nozzle 100 by 180 degrees so that the comb teeth 113b point downward, and the combing work can be continued.

Obviously, in the second embodiment, the positions of the carding opening 165 and the air leakage window 166 are continuously exchanged. Such as the combing opening 165, when it is positioned below, the comb teeth 113a are stretched outwards for combing. After the suction nozzle 100 is overturned, the combing opening 165 turns to the top, and the comb teeth 113b turn to the bottom for combing. At this time, the combing opening 165 is actually transformed into the air leakage window 166, and the air leakage window 166 is actually transformed into the combing opening 165. .

As shown in FIG. 14 , the length L of the damper 152 is not less than the length O of the distribution range of the comb teeth on the base 112 , and the length K of the leading area 160 a is not less than the length L of the damper 152 . The depth M of the leading area 160a along the suction airflow direction is not less than 3 mm. When the comb teeth point to the damper 152 in the storage state, the distance between the tip of the comb teeth and the damper 152 is no more than 10 mm.

In the second embodiment, the upper cover part 110 and the lower cover part 111 are straight in shape. The upper cover part 110 can also be made to protrude upwards in an arc shape, and the shape of the lower cover part 111 can be made to protrude downwards in an arc shape. The optimum solution for the cross-sectional area of the damper 152 is to be smaller than the ventilation cross-sectional areas at the front and rear of the damper respectively, that is, the damper 152 is formed by shrinking the airflow channel.

Function and effect of embodiment two

According to the vacuum cleaner nozzle described in Embodiment 2, because the extension direction of the comb teeth is perpendicular to the axial direction of the rotating body, and the length direction of the damper is parallel to the axial direction of the rotating body, the length of the damper is not less than a row of comb teeth. The length of the distribution range on the base, at the same time, the air induction duct has a leading area connected with the air door, the length of the leading area is not less than the length of the air door, and the leading area has a certain depth in the direction from the air door to the interface member, so Whether it flows through the comb teeth located in the middle of the base or the comb teeth located at the left and right edges, the airflow direction is parallel or approximately parallel to the extension direction of the comb teeth, so that any comb wound on any comb teeth in the storage state Hair can be sucked into the damper with the wind.

In addition, because both the left bracket and the right bracket are made of relatively elastic materials, the combing member can be taken out only by moving the left bracket or the right bracket outward, so it is very convenient for the user to maintain and replace the combing member.

In addition, the suction nozzle of the vacuum cleaner in this embodiment only needs to be operated with one hand, so the operation is simpler and more convenient, and the suction nozzle of the vacuum cleaner is more portable and reliable because of its simple structure.
