When the pet hair cleaner is used, the pet hair is combed by the carding strips on the rolling cleaning piece, and the dust collection equipment is used for sucking dust on the pet body.

However, when the rolling cleaning piece rotates, the hair separated from the pet is easy to wind on the comb strip, so that the hair is difficult to suck by the dust collection equipment after the comb strip clamping belt hair enters the base cavity, the effect of combing the hair by the rolling cleaning piece and the adsorption effect of the dust collection equipment are influenced, and therefore, the accumulated hair on the comb strip needs to be cleaned manually frequently, and the use is inconvenient and the efficiency is low.

In view of this, the present application provides a hair cleaning structure and dust collecting equipment, through offer dodging the district on the casing, set up the rolling element that is provided with at least one broach piece in the casing rotation, the casing inner wall then is connected with and scrapes the hair piece, scrape the other end setting of hair piece and extend towards the rolling element; when the comb tooth piece rotates to the avoidance area along with the rolling body, the comb tooth piece can partially extend out of the shell to comb the pet hair, the comb tooth piece enters the shell, and in the process of continuing to rotate, the other end of the hair scraping piece connected with the inner wall of the shell is contacted with the comb tooth piece so as to push away the hair hung on the comb tooth piece. So need not the manual hair that accumulates on the broach and clear up, clearance efficiency is high and convenient to use.

The present application will now be described in detail with reference to the accompanying drawings and specific examples.

See fig. 1, 2 and 3. The hair cleaning structure provided by the application comprises a shell 100, a comb assembly 200 and at least one hair scraping member 300; the shell 100 is provided with an avoidance area 110, the comb assembly 200 comprises rolling bodies 210 and at least one comb tooth piece 220 arranged on the rolling bodies 210, and the rolling bodies 210 are rotatably arranged in the shell 100; the comb member 220 rotates along with the rolling bodies 210, and when the comb member 220 rotates to the avoidance area 110, part of the comb member 220 extends out of the housing 100; one end of the hair scraping member 300 is connected to the inner wall 101 of the housing 100, the other end of the hair scraping member 300 extends toward the rolling bodies 210, and the other end of the hair scraping member 300 contacts the comb member 220 to push away hair hanging when the comb member 220 partially protrudes outside the housing 100.

Specifically, referring to fig. 2, the housing 100 may include a first housing 130, a second housing 140, and a third housing 150, which together enclose a certain accommodating cavity, where the first housing 130 and the second housing 140 define an avoidance area 110, the rolling element 210 is rotatably disposed in the accommodating cavity of the housing 100, and at least one comb tooth member 220 is disposed on the rolling element 210. Wherein the comb teeth member 220 is used for performing a function of combing the pet hair, i.e., combing the pet hair and collecting foreign hair detached from the hanging pet body thereon.

The number of the comb teeth 220 is not limited, and it can be understood that the function of combing the pet hair can be realized by arranging one comb teeth 220, and more than two comb teeth 220 are arranged to be beneficial to improving the combing efficiency of the pet hair.

The scraping member 300 serves to push away the hair wound on the comb member 220. The hair scraping member 300 is disposed in the accommodating cavity, and one end of the hair scraping member 300 is connected with the inner wall 101 of the housing 100, wherein the inner wall 101 of the housing 100 is the surface of the housing 100 opposite to the rolling bodies 210; the other end of the scraper 300 extends toward the rolling element 210.

In a specific implementation, the comb member 220 rotates along one direction along with the rolling body 210, and when the comb member 220 rotates to the avoidance area 110, part of the comb member can extend out of the housing 100 through the avoidance area 110, one end of the comb member 220, which is close to the pet body, contacts with the pet body, and combs hair in the process of continuing to rotate.

When the comb member 220 continues to rotate along with the rolling element 210 from the avoiding area 110, and when the comb member 220 is opposite to the position of the scraping member 300 in the housing 100, since one end of the comb member 220 is connected to the inner wall 101 of the housing 100 and the comb member 220 needs to continue to rotate along with the rolling element 210, at this time, the other end of the scraping member 300 contacts with the position of the comb member 220 near the rolling element 210, and during the continuous rotation of the comb member 220, the position of the other end of the scraping member 300 changes from the position of the comb member 220 near the rolling element 210 to the position of the comb member 220 far from the end of the rolling element 210, and the other end of the scraping member 300 always contacts with the comb member 220.

It will be appreciated that continued rotation of the comb member 220 during this process causes the scraper member 300 to contact the comb member 220 to generate a force which deforms the two. In particular, the contact deformation is an elastic deformation, that is, one of the comb tooth part 220 and the bristle part 300 is elastically deformed with respect to the other and then can be restored to the original shape and size.

In the process that the position of the other end of the hair scraping member 300 is changed from the position of the comb tooth member 220 near the rolling body 210 to the position of the comb tooth member 220 far from the rolling body 210, the other end of the hair scraping member 300 applies a pushing force to the hair hung when the comb tooth member 220 is partially protruded out of the housing 100, that is, the hair moves toward the end of the comb tooth member 220 far from the rolling body 210 and is separated from the other end of the hair scraping member 300.

For example, refer to fig. 1. The avoiding area 110 is arranged below the housing 100, and the rolling elements 210 are arranged in a cylindrical structure, so that the rolling elements 210 can rotate relative to the housing 100. The rolling elements 210 are located in the housing 100 relatively close to the avoidance area 110, and the avoidance area 110 below the housing 100 is disposed opposite to the pet body, so that the comb teeth members 220 thereon can partially extend out of the housing 100 to comb the pet hair when rotating to the avoidance area 110. A hair scraping member 300 is provided at a certain position of the inner wall 101 of the housing 100.

The rotational direction of the rolling element 210 is not limited in this embodiment, and with continued reference to fig. 3, the rolling element 210 may continuously rotate in a counterclockwise direction, or the rolling element 210 may continuously rotate in a clockwise direction.

The specific materials of the comb teeth member 220 and the shaving member 300 are not limited in this embodiment. Illustratively, the comb member 220 may be deformed in contact with respect to the scraper member 300, or the scraper member 300 may be deformed in contact with respect to the comb member 220. When the rolling element 210 rotates clockwise or counterclockwise, the comb element 220 and the scraping element 300 are opposite to each other, so that the position of the other end of the scraping element 300 is changed from the position of the comb element 220 near the rolling element 210 to the position of the other end of the comb element 220 far from the rolling element 210, and the other end of the scraping element 300 is always in contact with the comb element 220 and pushes away the hair on the comb element 220.

According to the hair cleaning structure, the avoidance area 110 is formed on the shell 100, the rolling body 210 provided with at least one comb tooth piece 220 is rotatably arranged on the shell 100, the inner wall 101 of the shell 100 is connected with the hair scraping piece 300, and the other end of the hair scraping piece 300 extends towards the rolling body 210; when the comb member 220 rotates to the avoidance area 110 along with the rolling bodies 210, the comb member 220 can partially extend out of the housing 100 to comb the pet hair, and in the process that the comb member 220 enters the housing 100 to continue rotating, the other end of the hair scraping member 300 connected with the inner wall 101 of the housing 100 is contacted with the comb member 220 to push away the hair hung on the comb member 220. The hair is prevented from accumulating on the comb teeth 220, and the hair accumulated on the comb teeth 220 is not required to be cleaned manually, so that the hair cleaning device has the advantage of being convenient to use, and the cleaning efficiency is improved.

See fig. 1 and 2. In some embodiments, the housing 100 defines a suction opening 120 in communication with the avoidance zone 110, the suction opening 120 being adapted to be coupled to a suction apparatus such that hair is collected within the suction apparatus via the suction opening 120.

Specifically, a suction port 120 is formed in the third casing, the suction port 120 is communicated with the avoidance area 110, and the suction port 120 is connected with dust collection equipment. During operation, the comb member 220 rotates along one direction along with the rolling body 210, when the comb member 220 rotates to the avoidance area 110, part of the comb member can extend out of the housing 100 through the avoidance area 110, one end of the comb member 220, which is close to the pet body, contacts with the pet body, and the hair is combed in the avoidance area 110 in a continuous rotating process.

When the comb member 220 continues to rotate from the avoiding area 110 along with the rolling elements 210, the other end of the hair scraping member 300 moves and sweeps from the position of the comb member 220 near the rolling elements 210 toward the end of the comb member 220 far from the rolling elements 210, and the other end of the hair scraping member 300 always contacts with the comb member 220 when the hair scraping member 300 is positioned opposite to the position of the hair scraping member 300 in the housing 100. In this process, the other end of the hair scraping member 300 pushes off the hair caught when the comb member 220 partially protrudes outside the housing 100, i.e., the hair moves toward the end of the comb member 220 away from the rolling bodies 210 and is separated from the other end of the hair scraping member 300.

The pushed-off hair is collected in the suction apparatus via the suction opening 120 inside the housing 100 by suction from the suction apparatus above the housing 100. By the design, the collection work of the separated hairs on the carding wire is realized, and the impurities Mao Piaosan are avoided, so that the user experience is influenced.

In some examples, the number of the hair-shaving elements 300 is one, and the hair-shaving elements 300 are disposed close to the suction opening 120; or, the number of the shaving pieces 300 is two or more, and the shaving pieces 300 are arranged at intervals on the inner wall 101 of the housing 100.

Specifically, the shaving member 300 attached to the inner wall 101 of the housing 100 is used to push away hairs that are caught when the comb member portion is extended out of the housing 100. Referring to fig. 3, when the number of the hair scraping members 300 is one, by disposing the hair scraping members 300 close to the suction port 120, the action of separating the hair from the comb teeth needles occurs in the housing 100 at a position close to the suction port 120, which is advantageous in that the hair is collected into the dust collecting apparatus through the suction port 120 once separated, and the hair is prevented from drifting in the housing 100 and being wound around the comb teeth members 220 again.

When the number of the shaving pieces 300 is two or more, one end of each shaving piece 300 is disposed at an interval on the inner wall 101 of the housing 100, and the other end of each shaving piece 300 extends toward the rolling element 210. This facilitates the removal of hair from comb member 220 by the plurality of hair scraping members 300.

See fig. 3 and 4. In a specific example, the scraping member 300 includes a scraper Mao Benti 310 and a soft scraping strip 320 provided on the scraping body 310, the scraper Mao Benti 310 is connected to the inner wall 101 of the housing 100, the extending direction of the soft scraping strip 320 is parallel to the axial direction of the rolling body 210, and the soft scraping strip 320 is in contact with the comb member 220.

Specifically, the scraper Mao Benti 310 is connected to the inner wall 101 of the housing 100 to achieve mounting and fixing of the scraper 300 on the inner wall 101 of the housing 100. The soft scraping strip 320 is used to push away hairs that are caught when the comb member 220 partially protrudes outside the housing 100. It will be appreciated that one end of the soft wiper strip 320 is connected to the wiper body 310 and the other end extends toward the rolling bodies 210.

It will be appreciated that when the pet hair is combed, the process that the comb member 220 rotates along with the roller from the avoiding region 110 and returns to the avoiding region 110 is repeated several times, and the extending direction of the soft scraping strip 320 is parallel to the axial direction of the rolling body 210, and the soft scraping strip 320 contacts with the comb member 220, so that the interval between the rolling body 210 and the soft scraping strip 320 is kept constant in the continuous rotation process. This ensures that the comb 220 on the roller 210 is pushed off the hair each time it contacts the soft blade 320, which is advantageous to maintain the hair cleaning effect and stability.

By providing the soft scraping strip 320, in the process that the soft scraping strip 320 contacts with the comb member 220 and pushes away the hair hung on the comb needle, it can be understood that when the comb member 220 continues to rotate along with the rolling body 210, the other end of the soft scraping strip 320 moves from the end, which is close to the rolling body 210, of the comb member 220 and is far away from the rolling body 210, on the ground direction of the comb member 220, and the other end of the hair scraping member 300 always contacts with the comb member 220, and the hair on the comb member 220 moves toward the end, which is far away from the rolling body 210, on the comb member 220, along with the other end of the soft scraping strip 320. The soft nature of the soft wiper strip 320 prevents it from severely impeding the rotation of the rolling elements 210.

In a specific example, the wiper Mao Benti 310 is screwed to the inner wall 101 of the housing 100.

Specifically, two through holes are formed at two ends of the extending direction of the shaving body 310, wherein the extending direction of the shaving body 310 is consistent with the extending direction of the soft shaving strip 320. Two threaded holes are formed in the inner wall 101 of the shell 100, wherein the threaded holes are in one-to-one correspondence with the through holes, and screws penetrate through the through holes to be connected with the threaded holes. This facilitates the mounting of the bristle sub 300 on the inner wall 101 of the housing 100.

It will be appreciated that the use of a screw connection provides a higher strength of connection, which may provide a more reliable connection of the wiper Mao Benti 310 to the housing 100; the screw connection has detachability, so that the shaving piece 300 is detachably connected with the shell 100, and when the shaving piece 300 needs to be detached and replaced, the operation can be completed only by loosening the screw; and the installation of the screw connection is relatively simple, and the scraper Mao Benti 310 can be installed on the inner wall 101 of the casing 100 by using a wrench or a screwdriver, for example; furthermore, the economical practicability of the screw is good, and the cost can be saved by adopting screw connection.

In some embodiments, the comb 220 and the soft wiper 320 are flush at the same side end.

Specifically, it can be understood that when the comb member 220 rotates into the housing 100 along with the rolling body 210 and is opposite to the soft scraping strip 320, the end of the comb member 220 away from the rolling body 210 and the end of the soft scraping strip 320 connected to the shaving body 310 are on the same side; the comb member 220 is disposed on the same side as the other end of the soft wiper 320 extending toward the rolling body 210 at one end of the rolling body 210.

By arranging the comb teeth piece 220 to be flush with the end parts of the same side of the soft scraping strip 320, when the soft scraping strip 320 contacts with the comb teeth piece 220 and continues to rotate, on one hand, the soft scraping strip 320 can be ensured to contact with all hairs hung on the comb teeth piece 220 when the soft scraping strip is partially extended out of the shell 100 and exert thrust on the hairs, so that the hairs on the comb teeth piece 220 are favorably separated sufficiently; in the second aspect, the rolling element 210 may be prevented from twisting or shaking when the part of the comb element 220 is still in contact with the soft scraping strip 320 in the axial direction of the rolling element 210 and the other part of the comb element is deviated from the soft hanging strip to rotate toward the avoiding area 110. It is advantageous to maintain the rotation of the rolling elements 210 with good stability.

In some examples, the soft wiper 320 is curved in an arc shape that curves the rolling elements 210 toward the ends of the rolling elements 210.

Specifically, the end of the soft scraping strip 320 facing the rolling element 210 is provided with an arc shape bent by the rolling element 210, when the comb tooth piece 220 is opposite to the soft scraping strip 320, the arc end of the soft hanging strip contacts with the comb tooth piece 220 and pushes away the hair hung when the comb tooth piece 220 partially extends out of the shell 100, and when more hair is on the comb tooth piece 220, the arc part of the soft scraping strip 320 can hold the hair in the pushing-away process; after the hair is completely separated from the comb member 220, the arc portion may serve to collect the hair. This prevents hair from drifting away.

In a specific example, the comb teeth 220 are provided at least two at intervals along the circumferential direction of the rolling body 210.

Specifically, at least two comb teeth members 220 are disposed at intervals along the circumferential direction of the rolling body 210, so that the comb efficiency of the pet hair can be improved. Illustratively, referring to fig. 3, five comb teeth 220 are disposed at equal intervals in the circumferential direction of the rolling body 210, each comb tooth 220 alternately protrudes out of the housing 100 through the escape area 110 to comb the pet hair, and each comb tooth 220 alternately contacts with the shaving member 300 to disengage the hair thereon.

See fig. 4. In some embodiments, the comb member 220 includes a stopper bar 221 and a plurality of comb teeth 222 disposed on the stopper bar 221, the stopper bar 221 having an extending direction coincident with an axial direction of the rolling body 210, and the comb teeth 222 being spaced apart along the extending direction of the stopper bar 221.

Specifically, the stopper bar 221 serves to prevent hair from being entangled to the bottom of the comb gear; each comb tooth 222 untwists the entangled and knotted hair by combing the pet hair together when rotated into the dodge region 110.

For example, the stop bar 221 has a certain length along the axial direction of the rolling element 210, and the length of the stop bar 221 is not greater than the axial length of the rolling element 210, and in a specific implementation, the length of the stop bar 221 is consistent with the axial length of the rolling element 210, so that as many comb teeth 222 as possible can be arranged on the stop bar 221 at intervals, which is beneficial to improving the comb efficiency of hair. Further, the extending direction of the stop bar 221 is consistent with the axial direction of the rolling element 210, so when a plurality of comb teeth 220 are provided, the layout of each comb teeth 220 on the rolling element 210 can be designed to be reasonable, so that the distance between two adjacent comb teeth 220 in the axial direction of the rolling element 210 is kept constant.

See fig. 5. In some examples, the rolling bodies 210 rotate in a counterclockwise direction and the comb 220 bends in a clockwise direction.

Specifically, the rolling element 210 rotates counterclockwise, the comb element 220 is curved clockwise, when the comb element 220 rotates into the housing 100 along with the rolling element 210, the hair path pushed away from the comb element 220 when the other end of the hair scraping element 300 contacts with the comb element 220 is arc-shaped towards the axis of the rolling element 210, so that the resistance generated by the rotation of the rolling element 210 when the hair scraping element 300 contacts with the comb element 220 is reduced on the basis that the hair scraping element 300 pushes away the hair hung on the comb element 220.

See fig. 4. In a specific example, the comb member 220 and the rolling bodies 210 are integrally formed.

Specifically, the comb teeth 220 and the rolling body 210 are integrally formed, so that the problem of loose connection between the comb teeth 220 and the rolling body 210 can be avoided, namely, when the rolling body 210 rotates relative to the housing 100, the comb teeth 220 can rotate along with the rolling body 210, which is beneficial to improving the hair combing efficiency of pets. The adoption of the integral molding can avoid the connection between the comb teeth part 220 and the rolling body 210 and the additional processing process, thereby being beneficial to improving the production efficiency and reducing the production cost.

In some possible embodiments, the drive assembly 400 includes a drive shaft through which the drive assembly 400 is coupled to the rolling elements 210, and the drive assembly 400 transmits power to the rolling elements 210 through the drive shaft. When the driving assembly 400 is started, the driving shaft is rotated, and the rolling bodies 210 are driven to rotate together.

Illustratively, the drive assembly 400 includes a motor having an output shaft coupled to the rolling element 210, and upon actuation of the motor, the rolling element 210 is acted upon by the torque output by the output shaft to rotate with the motor.

See fig. 6. In a specific example, the drive assembly 400 is a belt drive assembly.

In particular, the belt drive assembly acts as a mechanical transmission for transmitting power to the rolling elements 210.

The belt drive assembly illustratively includes a motor 410, a drive pulley 420, a belt 430, and a driven pulley 440. The motor 410 is used to provide driving force, fix the driving wheel 420 on the output shaft of the motor 410, fix the driven wheel 440 on one end of the rolling body 210 in the axial direction, and the belt 430 connects the driving wheel 420 and the driven wheel 440, which are flexible belt-shaped members, transmitting power from the driving wheel 420 to the driven wheel 440 by friction. The axes of the output shaft, the driving wheel 420, the driven wheel 440, and the rolling elements 210 are parallel to each other. The driving wheel 420 transmits power by contact with the belt 430 under the driving of the motor 410, and the driven wheel 440 receives power by contact with the belt 430 and drives the rolling bodies 210 to rotate.

The belt driving assembly is adopted, so that the stability of the transmission process is facilitated, vibration and noise can be reduced, and the user experience is improved; and the belt 430 has a certain elasticity to absorb impact and shock.
