Description

[Technical Field]

[0001] The present invention relates to the field of pet combing, and in particular to an adjustable combing structure. [Background technology]

[0002] Pets such as pet cats and dogs generally shed a lot of hair during certain seasons, and even on weekdays, pets shed a lot of hair. Pet hair can stick to various indoor objects and to the human body, affecting hygiene and, if accidentally ingested by pets, affecting their digestion. Summary of the Invention [Problem to be solved by the invention]

[0003] To solve the above problem, a hair comb is generally installed in the path of the pet, and a hair combing structure is installed on the hair comb, so that the hair on the pet's body can be automatically combed and removed while the pet is passing through the hair comb.

[0004] However, in the prior art, there are pet combers whose inner diameter cannot be adjusted, which makes them incompatible with pets of different body types. On the other hand, there is a pet comber with an adjustable inner diameter, such as the automatic pet combing device described in Chinese Patent Publication No. 111248097, which uses a cylinder to adjust the combing mechanism. However, the inner diameter of the passageway after adjustment is still fixed, so the size of the inner diameter of the passageway can only be adjusted to accommodate pets of different body types, and the adjusted passageway can only accommodate pets whose body types are smaller than the inner diameter of the passageway.

[0005] In the above technology, when adjusting the diameter of the holes in the comb, if the passage is relatively small, the pet cannot pass through smoothly. Even in such a case, when the pet passes through the narrow passage, the pet's body will inevitably be pressed against the passage formed by the comb, and the wall of the holes in the comb will cause pain and discomfort to the pet as it passes through. Pets are generally very sensitive to pain and discomfort, which will likely cause the pet to dislike passing through the comb again, causing the comb to be unable to perform its combing function. Therefore, the diameter of the holes in the passage of the comb is generally made larger than the size of the pet's body, so that the pet can pass through smoothly. The hole diameter of the hair comb can be made relatively large to allow the pet to pass through smoothly, but in this case, the combing structure inside the hair comb cannot come into contact with the pet's body or the contact force is relatively small, so the combing force on the pet's body is not effective and the hair on the pet's body cannot be combed off relatively well.

[0006] SUMMARY OF THE INVENTION The present invention is directed to providing an adjustable pet combing structure that provides a combing path for a pet and allows for the size of the path to be adjusted. [Means for solving the problem]

[0007] To achieve the above object, the present invention adopts the following technical solution: the adjustable combing structure includes a housing and a combing unit mounted on the housing for combing pet hair and collecting the pet hair, a passage for the pet to pass through is opened on the housing, and an adjustment unit is provided on the housing for moving the combing unit closer to or away from the center of the passage. The principle and advantages of this solution are as follows:

[0008] 1. In practical application, the adjustable hair-combing structure of this solution is attached to the entrance of a pet's entrance, such as the entrance of a cat litter box. When the pet passes through the passage on the housing of this solution, the hair-combing unit automatically combs the hair on the pet's body, eliminating the need for the owner to comb the pet's hair by themselves. The hair-combing unit can also collect the hair that has fallen off the pet's body, thereby preventing the hair that has fallen off the pet's body from scattering in all directions, preventing the health problem of hairballs caused by pets accidentally eating too much hair, and maintaining a hygienic, clean and tidy indoor environment.

[0009] 2. In this solution, an adjustment unit is installed, which can not only move the combing unit closer to the center of the housing passage, but also adjust the combing unit to move away from the center of the housing passage, thereby adjusting the position of the combing unit according to the pet's body shape, so that the combing unit can effectively comb the pet's body, and broaden the application range of the combing structure in this solution.

[0010] Preferably, as a refinement, said adjustment unit comprises a cam disc on which an operating curve is provided that fits onto the combing unit, the combing unit abutting against the operating curve on the cam disc.

[0011] In this solution, the operating curve on the cam disc abuts against the combing unit, and when the cam disc is driven to rotate, the operating curve on the cam disc produces a pushing action on the combing unit, thereby moving the combing unit away from or towards the center of the housing passage, thereby adjusting the position between the combing unit and the center of the passage, so that the combing unit can be adapted to use by pets of different body types.

[0012] In this solution, the combing unit contacts the operating curve on the cam disc, and the operating curve on the cam disc limits the lower limit of the combing unit, acting as a one-sided stop. After adjusting the distance between the combing unit and the center of the passageway in accordance with the operating curve on the cam disc, the cam disc stops rotating. At this time, the operating curve on the cam disc limits the position of the combing unit, preventing it from approaching the center of the passageway in the housing any further. When a pet passes through the passageway and comes into contact with the combing unit, the pet itself can push the combing unit away from the passageway. When adjusting the position of the combing unit, the distance between the combing unit and the passageway can be appropriately adjusted to be smaller than the pet's body size. After completing the adjustment of the combing unit to the lower limit position, when the pet passes through the passage of the housing and comes into contact with the combing unit, the combing unit can fit the pet's body, and the force in the process of removing hair from the pet is greater, thus ensuring that the combing unit can perform a very effective combing action on the pet.

[0013] Also, at this time, the operating curve of the cam disc only limits the state in which the combing unit approaches the center of the passage, but the combing unit can still expand outward, so that the pet can push the combing unit outward and pass through smoothly while passing through the passage of the housing, and since the combing unit cannot expand outward during the passing process, it will not push the pet and cause pain to the pet, thereby avoiding the occurrence of the pet being reluctant to go through the combing structure of this solution again.

[0014] In this solution, the distance between the combing unit and the center of the passage can be increased or decreased according to the different body shapes of pets, and the size can be freely changed, thereby making it easier for pets of different body shapes to pass through. During the process of the pet passing through, the inner diameter of the combing unit can automatically change according to the changes in the pet's body shape, so there is no need to frequently adjust the size of the passage, which is more convenient and practical.

[0015] Preferably, as an improvement, a plurality of said combing units are provided, the plurality of combing units being distributed on one side of the passage of the housing.

[0016] In this solution, the installation of multiple combing units can enlarge the combing range of pets, and can effectively improve the combing effect of pets.

[0017] Preferably, as an improvement, an elastic member is provided between both the combing unit and the housing.

[0018] In this solution, an elastic member is provided between the combing unit and the housing, and the elastic member has elasticity, and the restriction of the elastic member allows the combing unit to fit the pet's body better when the pet passes through the passage and pushes the combing unit, so that a certain pressing force is maintained between the combing unit and the pet, thereby allowing the combing unit to more effectively remove and comb the pet. In addition, the action of the elastic member allows the pet to return after passing through the passage, making it easy to perform effective combing and hair removal on the pet again when the pet passes through the passage again.

[0019] Preferably, as an improvement, the inside of the housing is hollow, and the combing units are provided in two sets, the two sets of combing units being located on both sides of the housing, respectively.

[0020] By installing in this manner, the combing units on both sides of the housing can increase the area and number of times combing is performed on the pet, thereby achieving the effect of combing the pet twice during the pet's journey.

[0021] Preferably, as an improvement, the two sets of combing units on either side of the housing are arranged offset from each other.

[0022] When adjusting the combing units to match, adjacent combing units move closer to each other, but when the pet passes through the combing units, the combing units are pushed outward, increasing the diameter through which the pet passes. This causes adjacent combing units on the same side to be spaced apart from each other, resulting in a gap between them, which prevents the combing units from combing the entire circumference of the pet's body and results in incomplete combing of some parts of the pet's body. In this solution, two sets of combing units are installed interlaced, so that one combing unit fills the gap between the other combing units, thereby making the combing area on the pet's body more comprehensive, improving the combing effect and ensuring that most parts of the pet's body can be combed. Preferably, as an improvement, the adjustment unit further includes a drive unit for driving and rotating the adjustment unit, the drive unit including a worm wheel, a worm screw, and a motor, the motor drives and rotates the worm screw, the worm wheel meshes with the worm screw, and the worm wheel is connected to the cam disc.

[0023] In this solution, the adjusting unit is driven and rotated by a worm wheel and worm screw mechanism, which is more automated.

[0024] Preferably, as an improvement, each of the combing units includes a collection box and a combing roller, each of the collection box has an opening at both ends, the combing roller is rotatably connected to one of the openings of the collection box, a plurality of hair removal brushes are provided on the combing roller along its circumferential direction, and a hair removal brush is provided in the collection box, and the hair removal brush can be brought into contact with the hair removal brush when the combing roller is rotated.

[0025] By installing it in this way, in this solution, when the pet passes over the hair combing roller, the hair removal brush on the hair combing roller will comb off the hair that has fallen off the pet's body, thereby automatically performing the functions of combing and removing the hair on the pet's body; and the hair combing roller allows the hair removal brush on the hair combing roller and the hair removal brush to come into contact and rub against each other as it rotates, thereby removing the hair on the hair removal brush, which then detaches from the hair removal brush and enters the collection box, allowing the hair removal brush to fully perform the functions of combing and removing the pet's hair.

[0026] Preferably, as an improvement, a baffle is connected to the outside of the combing roller along its axial direction.

[0027] In this solution, a baffle is installed on the combing roller, so that the installation of the baffle allows the pet to move the baffle to rotate the combing roller while passing through the combing roller, and on the other hand, the installation of the baffle can prevent the pet's hair from wrapping around the combing roller, especially for some pets with relatively long hair, when the hair that falls from the pet is relatively long, the baffle can act as a barrier for the hair removal brushes on both sides, thereby preventing the long hair from stretching from the hair removal brush on one side of the baffle to the hair removal brush on the other side, causing the long hair to wrap around the combing roller and cause nodules.

[0028] Preferably, as an improvement, a comb tooth plate is connected onto the combing roller, and a plurality of comb teeth that are bent to the same side are connected onto the comb tooth plate, and the comb teeth have elasticity.

[0029] By installing it in this way, in this solution, the installation of the comb tooth plate allows the pet's hair to be combed as the pet passes through the combing roller, thereby making the pet's hair smoother and effectively reducing the occurrence of knots in the pet's hair, and also combing and collecting the hair that has already fallen off the pet's body.

[0030] Furthermore, if knots form on the remaining hair on a pet's body, the knotted hair will easily get caught on the comb teeth as the pet passes through the combing roller, hindering the pet's movement and causing the pet's hair to be pulled, which is likely to cause pain to the pet and discourage the pet from combing again. The comb teeth in this solution are elastic, so that in the above case, the knotted hair on the pet can still easily pass through the comb teeth, and after the pet passes through the combing roller, the knotted hair will pull and deform the comb teeth, allowing the pet to pass through smoothly, thereby preventing the knotted hair on the pet from being forcibly torn off the comb teeth and causing pain to the pet.

DETAILED DESCRIPTION OF THE INVENTION

[0032] The invention will be described in further detail below with reference to the detailed description of the invention.

[0033] The drawing symbols in the drawings of the specification include the top cover 1, the combing unit 2, the collection box 3, the combing roller 4, the stopper plate 5, the guide block 6, the guide plate 7, the housing 801, the first slide plate 8, the second slide plate 9, the motor 10, the worm screw 11, the worm wheel 12, the cam disc 13, the connecting plate 14, the operating curve 15, the guide hole 16, the rotating block 17, the return member 18, the depilating brush 19, the positioning shaft 20, the mounting block 21, the stopper block 22, the depilating brush 23, the baffle 24, the comb teeth 25, the mounting groove 26, and the base 27.

[0034] Example 1 The embodiment is basically shown in Figures 1, 2 and 3. The adjustable combing structure includes a housing 801, a combing unit 2 for combing pet hair and collecting pet hair, which is mounted on the housing 801, a passage for allowing the pet to pass through is opened on the housing 801, and an adjustment unit is provided on the housing 801 for moving the combing unit 2 closer to or away from the center of the passage.

[0035] In this embodiment, a plurality of combing units 2 are provided, and the plurality of combing units 2 are distributed on one side of the passageway of the housing 801. In this embodiment, the inside of the housing 801 is hollow, and two sets of combing units 2 are provided, and the two sets of combing units 2 are located on both sides of the housing 801, respectively, and the number of combing units 2 in each set is six, and the six combing units 2 in each set are uniformly distributed along the circumferential direction of the housing 801, and the six combing units 2 form a passageway for the pet to pass through.

[0036] In this embodiment, the two sets of combing units 2 on both sides of the housing 801 are offset from each other, specifically, the two sets of combing units 2 are offset from each other by 25 to 35 degrees. In this embodiment, the two sets of combing units 2 are offset from each other by 30 degrees, so that the two sets of combing units 2 can comb each part of the pet more thoroughly and more comprehensively, effectively ensuring that most parts of the pet's body can be combed.

[0037] In this embodiment, the housing 801 includes a first sliding plate 8 and a second sliding plate 9, and the two sets of combing units 2 are uniformly distributed in the circumferential direction on the first sliding plate 8 and the second sliding plate 9, respectively. In this embodiment, the two sets of combing units 2 are slidably fitted into the first sliding plate 8 and the second sliding plate 9, respectively, in the radial direction.

[0038] The first sliding plate 8 and the second sliding plate 9 are connected to each other. In this embodiment, the first sliding plate 8 and the second sliding plate 9 are engaged with each other and then fixed by screws, so that an accommodation space is formed between the first sliding plate 8 and the second sliding plate 9.

[0039] As shown in FIGS. 2 and 3 , the adjustment unit includes a cam disc 13, on which an operating curve 15 is provided to fit the combing unit. A through-hole is drilled in the center of the cam disc 13 to facilitate the passage of the pet. The combing unit 2 abuts against the operating curve 15 on the cam disc 13. In this embodiment, six operating curves 15 are provided on both the front and rear ends of the cam disc 13, and the six combing units 2 on both sides of the housing 801 abut against the six operating curves 15 on the front and rear ends of the cam disc 13, respectively. The operating curves 15 on the front and rear ends of the cam disc 13 are directed in opposite directions. In this embodiment, the operating curves 15 on the cam disc 13 are all involute curves. In this embodiment, the cam disc 13 is located in the cavity between the first slide plate 8 and the second slide plate 9.

[0040] As shown in FIG. 5, each combing unit 2 includes a collection box 3 and a combing roller 4. The collection box 3 has a fan-shaped exterior, and has openings on both ends. The combing roller 4 is rotatably connected to one of the openings of the collection box 3. In this embodiment, the combing roller 4 is attached to the narrower side of the opening of the collection box 3. A guide plate 7 is fixedly connected to one end of the collection box 3, and a stopper plate 5 is fixedly connected to the end of the guide plate 7 away from the collection box 3. The stopper plate 5 and the guide plate 7 are both rectangular plate-shaped structures, and the width of the stopper plate 5 is greater than that of the guide plate 7. A guide block 6 is fixedly connected to the top of the stopper plate 5.

[0041] 6 , six guide holes 16 are formed on the first sliding plate 8, and all of the guide holes 16 are strip-shaped holes, and the six guide holes 16 are uniformly distributed around the circumference of the first sliding plate 8, with the ends of the six guide holes 16 that are farther from the center of the first sliding plate 8 penetrating the side wall of the first sliding plate 8. In this embodiment, six uniformly distributed guide holes 16 are also formed on the second sliding plate 9, and the ends of the guide holes 16 on the second sliding plate 9 that are farther from the center of the second sliding plate 9 all penetrating the side wall of the second sliding plate 9.

[0042] The guide plate 7 on the collection box 3 can pass through the guide hole 16, but the stopper plate 5 cannot pass through the guide hole 16. Thus, in the process of assembling the combing unit 2 to the first sliding plate 8 and the second sliding plate 9, the collection box 3 and the stopper plate 5 are located on both sides of the first sliding plate 8 or the second sliding plate 9, respectively. In this way, the stopper effect on the collection box 3 is improved, and the process of the collection box 3 sliding along the first sliding plate 8 or the second sliding plate 9 is more stable.

[0043] During the installation of the collecting box 3, the guide plate 7 is inserted into the guide hole 16, so that the collecting box 3, the stopper plate 5, and the guide block 6 are positioned on both sides of the first slide plate 8 or the second slide plate 9, and the guide blocks 6 on the multiple collecting boxes 3 are positioned on the operating curve 15 of the cam disc 13 in turn and abut against the operating curve 15 of the cam disc 13 respectively.

[0044] An elastic member is provided between each of the combing units 2 and the housing 801. Specifically, in this embodiment, this elastic member is provided between one of the combing units 2 and the first slide plate 8 and between another of the combing units 2 and the second slide plate 9, and the elastic member here is a constant force spring (not shown).

[0045] In this embodiment, grooves (not shown) for mounting six constant force springs are uniformly distributed on the circumference of the first slide plate 8 and the second slide plate 9, and one end of each constant force spring is hooked onto the guide block 6. When the six combing units 2 on the first slide plate 8 and the second slide plate 9 are located at the lower limit position of the operating curve 15 of the cam disc 13, that is, when the combing units 2 are located at the position on the operating curve 15 of the cam disc 13 where the distance from the center of the housing passage is the smallest, the inner diameter of the passage formed between the combing units 2 is the smallest, and at this time the constant force springs are in their natural, unstretched state. After the constant force spring is installed to adjust the inner diameter of the passage formed between the combing units 2, the combing units 2 can automatically return to their original position after being pushed outward by the pet and expanding outward, facilitating effective combing the next time the pet passes through. Furthermore, the elastic member allows the combing units 2 and the pet's body to fit snugly together, improving the combing force on the pet and thereby improving the combing effect on the pet. As shown in FIG. 2 , the adjustable combing structure of this embodiment further includes a drive unit for driving and rotating the adjustment unit. The drive unit includes a worm wheel 12, a worm screw 11, a motor 10, and a reducer. The motor 10 drives and rotates the worm screw 11, and the power of the motor 10 is transmitted to the worm screw 11 after being reduced in speed via the reducer, thereby rotating the worm screw 11. The worm wheel 12 meshes with the worm screw 11, and the worm wheel 12 is fixedly connected to the cam disc 13. In this embodiment, the worm wheel 12 is an incomplete worm wheel 12, and the arc length of the worm wheel 12 is one-sixth of a full circle. This arrangement not only makes effective use of the effective number of teeth of the worm wheel 12 and ensures that the rotation of the worm wheel 12 moves and rotates the adjusting unit, but also reduces the volume of the worm wheel 12.

[0046] A connecting plate 14 is fixedly connected between the inside of the worm wheel 12 and the cam disc 13, so that the worm wheel 12 can move and rotate the cam disc 13 when it rotates.

[0047] As shown in Figure 4, in this embodiment, the top end of the first sliding plate 8 and the second sliding plate 9 are connected to the top cover 1 by screws, and the tops of the first sliding plate 8 and the second sliding plate 9 are located inside the top cover 1. The installation of the top cover 1 facilitates the installation of the motor 10, reducer, and worm screw 11, and can shield the drive unit, making it safer and more aesthetically pleasing.

[0048] As shown in Figure 7, a plurality of hair removal brushes 19 are mounted circumferentially on the combing roller 4, and a hair removal brush 23 is mounted in the collection box 3. When the combing roller 4 is rotated, the hair removal brushes 19 come into contact with the hair removal brushes 23. In this embodiment, a base 27 is connected to each of the collection boxes 3, and the base 27 is a hollow box-like structure. The combing roller 4 is rotatably connected to the base 27. In this embodiment, four grooves are formed circumferentially on the outer surface of the combing roller 4, and four hair removal brushes 19 are mounted thereon. The four hair removal brushes 19 are attached and fixed in the four grooves, thereby realizing the attachment and connection of the hair removal brushes 19 to the combing roller 4. Each hair removal brush 19 includes a brush cloth and bristles, with the bristles arranged on the brush cloth.

[0049] Two hair removal brushes 23 are provided in each collection box 3. In this embodiment, the two hair removal brushes 23 are respectively connected to both side walls of the base 27. In this embodiment, the hair removal brush 23 includes a hair removal cloth and some bristles, and some of the bristles are laid on the hair removal cloth. When the hair combing roller 4 is rotated, the hair removal brush 19 can be brought into contact with the hair removal brush 23, and the bristles of the hair removal brush 19 can come into contact with and rub against the bristles of the hair removal brush 23, scrubbing away pet hair that has stuck to the hair removal brush 19.

[0050] As shown in FIG. 8, a stopper structure for limiting the rotation width of the combing roller 4 is provided between the combing roller 4 and the base 27, and a return member 18 is provided between the combing roller 4 and the base 27.

[0051] In this embodiment, the positioning shafts 20 are fixedly connected to both of the two inner walls of the base 27, and the two positioning shafts 20 are installed symmetrically to each other, and the two positioning shafts 20 are located on the two inner walls of the base 27 to which the hair removal brush 23 is not connected.

[0052] As shown in FIGS. 7 and 8 , the stopper structure includes a stopper block 22 installed inside the base 27 and a rotating block 17 installed at one end of the combing roller 4. When the combing roller 4 rotates back and forth, both ends of the rotating block 17 can abut against symmetrical ends of the stopper block 22. In this embodiment, the stopper block 22 is cam-shaped, and both sides of the stopper block 22 have symmetrical inclined surfaces. The stopper block 22 is located on one side of one of the two positioning shafts 20, and a mounting block 21 is fixedly connected to one side of the other positioning shaft 20, with a U-shaped groove formed in the mounting block 21. In this embodiment, the stopper block 22 is fixedly connected to the base 27, and the stopper block 22 and the base 27 may be connected by adhesive fixing, screw fixing, integral molding, or other fixing methods.

[0053] In this embodiment, the rotating block 17 is fixedly connected coaxially with the combing roller 4, and has a shaft hole in the center of the rotating block 17, so that the shaft hole of the rotating block 17 can be easily inserted onto the positioning shaft 20 to realize the rotational fitting. In this embodiment, the rotating block 17 has a semicircular arc shape.

[0054] As shown in Fig. 8, the restoring member 18 in this embodiment is a constant force spring. When installing, the rotating blocks 17 and constant force springs at both ends of the combing roller 4 are inserted onto the two positioning shafts 20 in the base 27, respectively, and the end of the restoring member 18 is inserted into the groove of the mounting block 21, thereby achieving the purpose of connecting the combing roller 4 and the base 27, and allowing the restoring member 18 to return to its original position after deformation occurs.

[0055] In actual use, after the pet passes through the combing roller 4 and rotates it, the combing roller 4 can be returned by the action of the return member 18, thereby restoring the combing roller 4 to its initial state and facilitating the pet to be combed and depilated again. In this embodiment, a stopper structure is provided so that both ends of the rotating block 17 abut against both sides of the stopper block 22 to block the rotation of the combing roller 4, thereby achieving the purpose of restricting the rotation of the combing roller 4. In this way, the rotation range of the combing roller 4 in the forward and reverse directions is effectively restricted. During the process of the pet passing through the combing unit 2, the depilating brush 19 on the combing roller 4 can comb the pet, and the combing roller 4 rotates by itself, bringing the depilating brush 23 into contact with the depilating brush 19 to automatically remove the hair on the combing roller 4.

[0056] The specific implementation process is as follows: The motor 10 drives and rotates the worm screw 11, which in turn drives and rotates the worm wheel 12 meshing with it. The worm wheel 12 is connected to the cam disc 13, so that the worm wheel 12 drives and rotates the cam disc 13 as it rotates. As the cam disc 13 rotates, the operating curve 15 on the cam disc 13 presses against the guide block 6 on the collecting box 3, and the collecting box 3 on the first sliding plate 8 and the collecting box 3 on the second sliding plate 9 slide radially along the first sliding plate 8 and the second sliding plate 9, respectively, and fit into the center of the passage of the housing. When the guide block 6 is positioned at the lowest part of the operating curve 15 of the cam disc 13 (i.e., the position closest to the center of the cam disc 13), the inner diameter of the entrance passage formed between the six combing units 2 on the first slide plate 8 and the second slide plate 9 is at its smallest, and the inner diameter of the passage at this time is smaller than the body size of most pets.

[0057] During the actual adjustment process, according to the size of the pet's body, the guide block 6 is positioned at an appropriate position on the operating curve 15 of the cam disc 13, and the inner diameter of the passage formed between the multiple combing units 2 can allow the pet to pass through, and during the adjustment process, the inner diameter of the passage can be appropriately adjusted to be smaller than the pet's body size.

[0058] Because the operating curve 15 of the cam disc 13 acts as a one-sided stopper for the collection box 3, that is, after adjusting the position of the collection box 3, it can only independently restrict the movement of the collection box 3 toward the center of the housing passage, but cannot restrict the collection box 3 from expanding outward. Therefore, after the rotation of the cam disc 13 stops, a relatively large space is still left for the combing unit 2 to expand outward along the first sliding plate 8 and the second sliding plate 9, and the multiple combing units 2 cannot fit further inward and can only expand outward after being pushed by an external force. In this way, it can automatically adjust according to the pet's body size. As the pet passes through the passage, it pushes the combing units 2 outward, increasing the inner diameter of the passage formed between the multiple combing units 2, allowing the pet to pass through smoothly. Therefore, in this embodiment, when adjusting the position of the combing units 2, the passage formed between the combing units 2 can be made slightly smaller than the pet's body size. Even if the inner diameter of the passage between the combing units 2 after adjustment is smaller than the pet's body size, the pet can still pass through smoothly. As the pet passes through, the size of the inner diameter of the passage formed between the combing units 2 can be freely changed, and the pet will not feel any pain from being pressed.

[0059] In this embodiment, the operating curve 15 on the cam disc 13 can limit the degree of rebound to the middle due to the action of the elastic member of the combing unit 2.

[0060] When the pet passes through the passage formed between the six combing units 2, the combing roller 4 on the collection box 3 combs the hair on the pet's body. When the pet passes through this passage in the opposite direction, the combing roller 4 combs the pet's hair again and rotates in the opposite direction as the pet passes. As the combing roller 4 rotates in the opposite direction, it comes into contact with and rubs against the hair removal brush 23 on the base 27, thereby combing out the hair remaining on the combing roller 4 from the previous time the pet passed into the collection box 3.

[0061] In this solution, an elastic member is provided between the collection box 3 and the first sliding plate 8. Due to the restriction of the elastic member, the pet pushes the combing unit 2 outward when passing through the passage formed by the combing unit 2, and thus the combing unit 2 and the pet's body can fit tightly together and come into contact with each other, so that there is a certain pressing force between the combing unit 2 and the pet, and therefore the combing unit 2 has a certain force when combing the hair on the pet's body, making it possible to more effectively remove and comb the pet's hair. In addition, the action of the elastic member can cause the combing unit 2 to return to its previously adjusted position after the pet passes through the passage formed by the combing unit 2, making it easier to perform effective combing and hair removal on the pet again when the pet passes through this passage next time.

[0062] Example 2 As shown in Fig. 9, the adjustable combing structure is different from the first embodiment as follows: a baffle 24 is connected to the outer periphery of the combing roller 4 along its axial direction. The baffle 24 is made of an elastically deformable material. In this embodiment, the baffle 24 is made of silica gel and has a rectangular shape. The baffle 24 is adhesively fixed to the combing roller 4.

[0063] The specific implementation process is as follows: when the pet passes through the passage in the reverse direction and comes into contact with the combing roller 4, the depilating brush 19 located on the other side of the baffle 24 can again perform the function of combing and removing the hair on the pet's body. In this way, as the pet repeatedly passes through the combing roller 4 and the combing roller 4 is rotated in the forward and reverse directions, the depilating brushes 19 on both sides of the baffle 24 and the depilating brushes 23 on both sides of the base 27 work together to remove the hair stuck to the depilating brush 19.

[0064] Furthermore, in this embodiment, due to the installation of the baffle 24, the pet moves the baffle 24 while passing through the combing roller 4, thereby rotating the combing roller 4, and the baffle 24 serves to assist the rotation of the combing roller 4. Meanwhile, the installation of the baffle 24 can prevent the pet's hair from wrapping around the combing roller 4. In particular, for some pets with relatively long hair, when the hair that falls from the pet is relatively long, the baffle 24 can act as a barrier against the depilating brushes 19 on both sides, thereby preventing the long hair from extending from the depilating brush 19 on one side of the baffle 24 to the depilating brush 19 on the other side, thereby preventing the long hair from wrapping around the combing roller 4 and causing knots.

[0065] Example 3 As shown in Fig. 10, the adjustable combing structure is distinguished from Example 2 as follows: a comb tooth 25 plate is connected on the combing roller 4, and multiple comb teeth 25 curved to the same side are connected on the comb tooth 25 plate, and the multiple comb teeth 25 are distributed at intervals.

[0066] The comb teeth 25 are bent away from the baffle 24, so that a reverse combing action can be generated on the pet's hair, resulting in a better combing effect. In this embodiment, two comb teeth 25 plates are provided, and the two comb teeth 25 plates are located on both sides of the baffle 24. This arrangement allows the combing and hair removal functions to be performed on the pet's hair when the pet passes over the combing roller 4 in both the forward and reverse directions.

[0067] In this embodiment, the comb teeth 25 plate is detachably connected to the combing roller 4. Specifically, a mounting groove 26 is formed along the axial direction of the combing roller 4, one end of the mounting groove 26 penetrates one end of the combing roller 4, and the comb teeth 25 plate is fitted into the mounting groove 26 to achieve attachment between the comb teeth 25 plate and the combing roller 4. This mounting method is more convenient and allows for easy replacement.

[0068] In this embodiment, the comb teeth 25 are elastic and deformable, and are made of a flexible material, specifically, a 90A low hardness material made of ABC resin.

[0069] In this embodiment, if knots form in the remaining hair on the pet's body, the knotted hair will easily get caught on the comb teeth 25 as the pet passes through the combing roller 4, hindering the pet's movement and causing the pet's hair to be pulled, which is likely to cause pain to the pet and discourage the pet from subsequently combing the hair through the combing roller 4. The comb teeth 25 in this embodiment are elastic and deformable, so that in the above case, the knotted hair on the pet can still easily pass through the comb teeth 25, and after the pet passes through the combing roller 4, the knotted hair will pull and deform the comb teeth 25, allowing the pet to pass through smoothly, thereby preventing the knotted hair on the pet from being forcibly torn off the comb teeth 25 and causing pain to the pet.

[0070] Example 4 As shown in Figure 11, the adjustable combing structure is different from the first embodiment in that the working curve 15 on the cam disc 13 is a slanted line. In this embodiment, a different working curve shape of the cam disc 13 is provided, which can also realize adjustment to the position of the combing unit 2 and act as a one-sided stopper for the combing unit 2.

Furthermore, those skilled in the art may make further modifications and improvements without departing from the technical solutions of the present invention, which are also within the scope of protection of the present invention, and none of these will affect the effectiveness of the implementation of the present invention or the applicability of the patent. The scope of the claims of this application should be determined by the content of the claims, and the description of the preferred embodiments of the invention in the specification may be used to interpret the content of the claims.
