Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pet grooming, and particularly relates to a grooming method and a grooming assembly. BACKGROUND

[0002] Pet cats, pet dogs and other pets usually shed a large amount of hair in specific seasons, and even in ordinary times, pets also shed a large amount of hair, which will be attached to various objects in the room and on the human body, affecting hygiene, and if the hair is eaten by pets, it will also affect the digestion of pets.

[0003] Therefore, in order to solve the above problems, a grooming device is usually installed in the passage through which the pet passes, and a grooming structure is arranged on the grooming device, so that the grooming device can automatically groom and remove the hair on the pet during the process of passing through the grooming device.

[0004] However, some grooming devices in the prior art cannot adjust the inner diameter of the passage, which cannot adapt to pets with different body types. Some grooming devices can adjust the inner diameter of the passage, but at the same time limit the grooming range of the grooming device. In the process of expanding the inner diameter of the passage, the originally complete annular grooming range will inevitably have a gap, and the larger the inner diameter of the passage, the larger the gap. Ultimately, when the pet passes through the passage, the grooming range of the grooming device on the pet's body is small, and the grooming efficiency is low. SUMMARY

[0005] The present application aims to provide a grooming method and a grooming assembly to solve the problem of grooming dead angles when pets pass through the grooming passage.

[0006] In order to achieve the above purpose, the present application provides a grooming method, which specifically comprises the following steps: At least two grooming units for grooming pets are arranged in the passage through which the pet passes; The grooming unit is arranged to be movable in a direction away from the center of the passage; The axis of the grooming area of the grooming unit is arranged to be offset based on the longitudinal axis of the passage, and the offset grooming area is asymmetric based on the longitudinal axis.

[0007] The working principle and beneficial effects of the scheme are that the longitudinal axis in the scheme is a vertical line of the channel based on the horizon, and when the pet freely passes through the channel, the longitudinal axis is a vertical line passing through the center of gravity of the pet. The distribution of the combing area of the combing unit in the channel is not a traditional symmetrical or uniform arrangement, but a bias reference line with the longitudinal axis of the channel, so that the symmetrical axis of the combing area is biased in a certain direction relative to the longitudinal axis. This setting makes the combing area form a stable, asymmetric spatial relationship based on the longitudinal axis in the cross section of the channel. When the pet passes through a channel of limited length in a natural state, the behavior pattern of the pet includes "entering the channel" and "walking out of the channel". When the pet travels from one end of the channel to the other end, it will turn around and return. In this process of going and returning, the body of the pet completes a 180-degree axial rotation relative to the fixed channel and combing area. At this time, the originally biased combing area forms a mirror image relationship for the pet going and returning.

[0008] By combining the asymmetric layout of the combing area with the mirror image movement of the pet, the combing effect is complementary. Specifically, for example: when the pet enters the channel, if the biased combing area mainly acts on the left side of the pet's body; when the pet walks out of the channel, due to the change of the direction of the pet's body, the position of the same combing area switches to the right side of the pet's body. By biasing the layout of the combing area, the effective range of the combing area automatically covers both sides of the pet's body through a natural round trip of the pet, realizing the complementarity of the combing area in time sequence and spatial position.

[0009] In addition, the combing unit has the ability to move in a direction away from the center of the channel, so that the combing unit can adaptively fit the body contour of pets of different sizes when passing through, ensuring that the comb teeth are in full contact with the hair and improving the efficiency and comfort of combing.

[0010] The scheme integrates the two combing processes of the pet entering and walking out of the channel into the movement of the pet through the principle of mirror image complementarity of the combing unit when the pet passes through the channel. Without the need for manual adjustment of the pet's posture or the angle of the combing device, the pet's body can be combed in most areas, greatly reducing the combing dead angle. Compared with the cat litter basin with a gear ring driving type telescopic combing ring disclosed in CN113383720A, the technology expands the combing range and improves the combing effect by setting two layers of staggered combing components on the shell. However, the scheme only needs to set a single layer of combing units to achieve the effect of setting "two layers of staggered" as described above, reducing the number of combing units and reducing costs.

[0011] The scheme also avoids the stress reaction of pets during the grooming process. The grooming unit is set to move away from the center of the channel. The pet will push the grooming unit outward to pass through the channel smoothly. During the passing process, the grooming unit will not cause compression to the pet and cause pain to the pet. Therefore, the pet will not be willing to pass through the grooming structure again. Moreover, the grooming process of the scheme is integrated into the simple behavior of the pet passing through the channel. There is no need to forcibly fix or chase, which reduces the tension and resistance of the pet. The pet completes the grooming passively in the autonomous motion, which is more natural and has no sense of oppression. It is especially suitable for cats that are sensitive to grooming.

[0012] (3) By adjusting the bias direction and amplitude of the grooming unit, the main grooming area can be flexibly set to adapt to the hair characteristics of different pet breeds or the specific grooming preferences of the owner. In combination with the slidable grooming unit, it can adapt to various body sizes from young pets to adult pets, and has strong versatility. Most importantly, the scheme provides a new idea for automatic grooming equipment. That is, the method integrates dynamic grooming logic into static environmental layout, simplifies the complexity of the mechanical structure, and provides an innovative and practical solution for realizing low-cost, high-efficiency automatic and self-service pet grooming equipment.

[0013] Optionally, the grooming areas are evenly distributed along the circumference of the channel. This ensures that the grooming areas are evenly distributed on the cross section of the channel, providing a stable and predictable initial spatial framework, facilitating control of the grooming coverage range after biasing, and avoiding the problem that the grooming dead angle cannot be effectively compensated by biasing due to uneven initial distribution.

[0014] Optionally, the grooming areas are evenly divided along the circumference of the channel. This makes the circumferential area occupied by each grooming area consistent, facilitating uniform bias angle calculation and adjustment, ensuring that the grooming range pattern formed after biasing has regularity and symmetry, which is beneficial to optimizing the mirror complementary effect and realizing the optimal grooming coverage in theory.

[0015] Optionally, the grooming range formed by the biased grooming unit does not coincide with the grooming range of the mirror image of the grooming unit relative to the longitudinal axis. This ensures that the effective action areas of the grooming unit during the pet's entry into the channel and turning to walk out of the channel are staggered on the surface of the pet's body, maximizing the total grooming coverage area of a single round trip and reducing the dead angle caused by the fixed layout of the grooming unit.

[0016] Optionally, the bias angle of the grooming area is set according to the formula The two calculated angle values are used as the upper limit and lower limit of the offset angle range, wherein Y is the number of the combing units arranged along the circumferential direction of the channel, and X is the ratio of the maximum distance dimension of the radial sliding of the combing unit to the initial distance dimension. The formula comprehensively considers the number Y of the combing units and the radial sliding ability X, calculates the critical value of the offset angle which can ensure the optimal state that the forward and return combing ranges do not overlap, and selects the offset angle in the range, which can ensure the effective complement of the forward and return combing of the pet.

[0017] Optionally, the offset angle of the combing region further comprises that the offset angle is calculated according to the formula The two calculated angle values are used as the upper limit and lower limit of the offset angle range, wherein N is an integer. The selection range of the effective offset angle is expanded, the offset angle is allowed to be superimposed on the integer multiple of the basic period by introducing the integer N, and the calculated angle value can be offset in any direction according to the absolute value of the angle value, regardless of the positive or negative value of the angle value. The positive or negative value of the angle value is not distinguished as the clockwise offset or the counterclockwise offset, and under the premise that the combing ranges after the mirroring do not overlap, one of the most suitable angles can be selected from the multiple effective angle options according to the space limitation or the specific combing effect requirement, thereby enhancing the applicability of the scheme.

[0018] Optionally, all the combing units divide the radial range of the channel into multiple sectors, the initial position of the combing unit is an inner equivalent sector, the position with the maximum sliding distance of the combing unit and the same central angle as the initial position is an outer equivalent sector, and the ratio of X further comprises the ratio of the inner chord length of the inner equivalent sector to the outer chord length of the outer equivalent sector, or the ratio of the inner arc length of the inner equivalent sector to the outer arc length of the outer equivalent sector, or the ratio of the inner equivalent combing dimension of the inner equivalent sector to the outer equivalent combing dimension of the outer equivalent sector. The theoretical formula is more consistent with the geometric characteristics of the actual combing unit, the offset angle range obtained by substituting these actual size ratios into the formula is more accurate and more consistent with the engineering practice, and the accuracy of the theoretical guidance to practice is improved.

[0019] Optionally, the combing units are six and arranged along the circumferential direction of the channel, and the ratio of the maximum distance dimension of the radial sliding of the combing unit to the initial distance dimension is , or the ratio of the inner chord length of the inner equivalent sector to the outer chord length of the outer equivalent sector is , or the ratio of the inner arc length of the inner equivalent sector to the outer arc length of the outer equivalent sector is . This embodiment is a preferred embodiment, and the offset angle calculated according to this parameter is a certain and unique angle value, that is, 15 degrees, and the offset combing assembly set according to 15 degrees can realize the combing without dead angle, which proves the feasibility and practicability of the scheme of the present application.

[0020] A grooming assembly includes a housing and a grooming unit mounted on the housing for grooming a pet. The housing has a channel for the pet to pass through, and the grooming unit is slidably connected to the housing and can move in a direction away from the center of the channel.

[0021] Optionally, an elastic element is provided between the grooming unit and the housing. Because of this elastic element, which is elastic, the grooming unit fits more closely to the pet's body as the pet passes through the channel, creating a certain pressure between them. This allows the grooming unit to more effectively remove and groom the pet's fur. Furthermore, the elastic element allows the pet to return to its original position after passing through the channel, facilitating effective grooming and fur removal the next time the pet passes through the same channel.

[0022] Optionally, the grooming unit includes a grooming stand for collecting pet hair. The grooming stand can directly collect shed hair during grooming, preventing hair from scattering and polluting the environment, simplifying subsequent cleaning steps, and improving ease of use.

[0023] Optionally, the grooming unit also includes a grooming roller, which is rotatably connected to the end of the grooming unit facing the channel, and has grooming teeth. The grooming roller can change sliding friction into rolling friction when grooming pet hair, reducing the pulling and irritation to the pet's skin during the grooming process, improving the pet's comfort when passing by, and reducing stress response.

[0024] Optionally, a baffle is connected to the outer side of the combing roller along its axial direction. The baffle on the combing roller serves two purposes: firstly, the pet moves the combing roller by pushing it along with the baffle as it passes over it; secondly, the baffle prevents pet hair from getting tangled on the combing roller, especially for pets with long hair. When pet hair is long, the baffle acts as a barrier between the brushes on either side, preventing long hair from extending from one brush to the other and becoming tangled on the combing roller.

[0025] Optionally, the grooming unit also includes a comb bar, which is located at the end of the grooming unit facing the channel, and has multiple comb teeth that bend to the same side. The flexible comb teeth that bend to the same side can better conform to the pet's body curves, reducing the pulling sensation on the skin during grooming, which is especially suitable for sensitive or pain-sensitive pets and improves the pet's comfort.

[0026] Optionally, the comb teeth are flexible. Flexible comb teeth can adapt to the density and thickness of the hair, deeply removing loose and dead hair from the pet's fur, while not easily getting hair stuck. It is suitable for various pet types, including long-haired and short-haired pets.

[0027] Optionally, two adjacent comb teeth are arranged in a cross configuration. This arrangement increases the contact area and working length for a single brushing stroke, better covering the pet's body, improving brushing efficiency, and further reducing blind spots during brushing.

[0028] Optionally, it also includes a drive mechanism for biasing the combing unit. Controlling the bias of the combing unit via the drive mechanism is particularly suitable for scenarios requiring frequent adjustments to the bias angle, improving the comfort and reliability of the combing process.

[0029] Optionally, the power output end of the drive unit is connected to a linkage mechanism, which drives the combing units to be biased simultaneously. The linkage mechanism transmits the power of the drive unit to all combing units simultaneously, ensuring they maintain a consistent bias angle and avoiding blind spots caused by asynchronous bias of the combing units. By controlling all combing units through a single drive unit in conjunction with the linkage mechanism, the number of independent drive components is reduced, which is beneficial for cost control.

[0030] Optionally, a sliding plate is rotatably connected within the housing, and the grooming unit is slidably connected to the sliding plate. The sliding plate has guide holes that slide and engage with the grooming unit. These guide holes are all strip-shaped and offset relative to the central axis of the channel, with an offset angle ranging from 0 to 90 degrees. By machining the guide holes themselves into strip-shaped holes offset at a certain angle relative to the central axis of the channel, the grooming unit installed within them is forced to slide along the guide holes, resulting in a spiral distribution of its movement trajectory relative to the pet's body. This ultimately expands the grooming range on the projected area and reduces blind spots in grooming.

[0031] Optionally, the casing is equipped with a scale corresponding to the offset angle of the grooming unit. The scale corresponds to the offset angle of the grooming unit, allowing users to personalize the offset angle of the grooming unit according to the length of their pet's fur or their personal preferences.

[0032] Optionally, the housing also includes a transparent cover for enclosing the combing components. The cover effectively isolates the internal moving parts, preventing accidental contact by pets or users and improving safety. The transparent cover also allows users to observe the hair collection, comb teeth status, and pet's reaction at any time, facilitating timely cleaning or adjustments. Attached Figure Description

Detailed Implementation

[0034] The following detailed description illustrates the specific implementation method: The markings in the accompanying drawings include: housing 1, cover 11, slide plate 12, guide hole 13, combing unit 2, combing seat 21, combing roller 22, baffle 23, combing rack 24, longitudinal axis 3, and channel 4.

[0035] Example 1 This embodiment is basically as follows: Figure 1 , Figure 2 As shown: A grooming assembly according to a grooming method includes a housing 1 and a grooming unit 2 for grooming a pet mounted on the housing 1. The housing 1 has a channel 4 for the pet to pass through. The grooming unit 2 is slidably connected to the housing 1. The grooming unit 2 can move in a direction away from the center of the channel 4. The axis of the grooming area of ​​the grooming unit 2 is offset based on the longitudinal axis 3 of the channel 4. The offset grooming unit 2 is asymmetrical based on the longitudinal axis 3.

[0036] like Figure 7 As shown, the vertical axis 3 is the vertical line of the channel 4 based on the horizon, and when the pet is freely passing through the channel 4, the vertical axis 3 is a vertical line passing through the pet's center of gravity.

[0037] In this embodiment, the housing 1 is hollow, serving as a passageway for the pet. In this embodiment, the grooming units 2 are single-layered and six in number, evenly distributed circumferentially along the housing 1. These six grooming units 2 form a passageway 4 for the pet, with the longitudinal axis 3 of the passageway 4 serving as the baseline for the layout of the grooming units 2. Spatially, all the single-layered grooming units 2 are arranged within the same cross-section parallel to the longitudinal axis 3 of the passageway. Figure 2 As shown, six grooming units 2 are evenly distributed and equidistant around the channel 4 of the housing 1, and located on the same cross-section. The six grooming units 2 are not arranged in layers or staggered along the direction of the pet's movement. The single-layer offset grooming units 2 achieve a similar or even better coverage effect to the two-layer staggered spatial structure in the time sequence of the pet's outward and return journeys. This directly reduces the number of grooming units 2 by about half, significantly reducing material costs. It not only reduces hardware but also demonstrates innovation in the method of reducing grooming dead angles. Furthermore, the single-layer grooming units 2 make the axial dimension of the entire grooming assembly smaller, making it easier for the pet to pass through the channel.

[0038] The entire combing assembly is covered by a transparent cover 11 made of acrylic material. This transparent cover 11 can prevent pets or users from accidentally touching the internal moving parts, and also allows the owner to observe the pet's status, hair collection, and the operating status of the equipment at any time.

[0039] Inside the housing 1, around the periphery of the channel 4, there is a circular slide plate 12. The slide plate 12 is rotatably connected to the housing 1, and the slide plate 12 constitutes a linkage mechanism that drives all combing units 2 to be synchronously biased. The slide plate 12 has six guide holes 13, which are all strip-shaped holes extending radially along the channel 4, and the six guide holes 13 are evenly distributed along the circumference of the slide plate 12.

[0040] Each combing unit 2 includes a slider, a combing base 21, and a combing roller 22.

[0041] The combing base 21 is fan-shaped and has a slider that is nested in the guide hole 13 of the slide plate 12. The slider allows the combing unit 2 to slide radially along the guide hole 13 and to change its offset angle synchronously with the rotation of the slide plate 12. The combing base 21 is used to receive and collect shed pet hair. Both ends of the combing base 21 have openings. The end of the combing base 21 facing the inner side of the channel 4 with a narrower opening is rotatably connected to a combing roller 22. The cylindrical surface of the combing roller 22 is covered with flexible combing teeth. A baffle 23 is connected to the outer side of the combing roller 22 along its axial direction. This baffle 23 is used to rotate the combing roller 22 during combing and to isolate long hair between adjacent combing tooth areas to prevent hair from tangling and knotting.

[0042] Both the combing unit 2 and the housing 1 are provided with elastic elements. Specifically, in this embodiment, the elastic element is provided between one set of combing units 2 and the slide plate 12. The elastic element here is a tension spring (not shown in the figure). Six grooves for installing tension springs are evenly distributed on the circumference of the slide plate 12. One end of the tension spring is hooked on the slider. When the combing unit 2 is in the initial position, that is, in the position with the smallest distance from the center of the channel 4, the inner diameter of the channel 4 formed between the combing units 2 is the smallest. At this time, the tension spring is in its natural unstretched state. The setting of the tension spring allows the combing unit 2 to automatically return to its original position after being pushed outward by the pet, which facilitates effective combing when the pet passes through again. In addition, the setting of the elastic element allows the combing unit 2 to fit closely to the pet's body, resulting in better combing force and thus improving the combing effect on the pet.

[0043] This embodiment also includes a drive device (not shown in the figure) for driving the combing unit 2 to be biased. The drive device includes a worm gear, a worm, a motor and a reducer. The motor drives the worm to rotate. The power of the motor is reduced by the reducer and then transmitted to the worm, thereby causing the worm to rotate. The worm gear meshes with the worm and is fixedly connected to the slide plate 12. In this embodiment, the worm gear is an incomplete worm gear. The arc length of the worm gear is one-sixth of a full circle. This setting can effectively utilize the effective number of teeth of the worm gear to ensure that the worm gear rotates and drives the slide plate 12 to rotate, thereby achieving the biasing of the combing unit 2, while reducing the volume of the worm gear.

[0044] A connecting plate is fixedly connected between the inner side of the worm gear and the slide plate 12. When the worm gear rotates, it can drive the slide plate 12 to rotate.

[0045] In this embodiment, the upper part of the slide plate 12 is covered inside the housing 1. This arrangement facilitates the installation of the motor, reducer, and worm gear, and can also shield the drive device, making it safer and more aesthetically pleasing.

[0046] This embodiment sets key parameters based on a combing method: such as... Figure 3 , Figure 4 As shown, the distribution and working principle of the combing unit 2 are simplified. In this embodiment, according to the formula... The two calculated angle values ​​are used as the upper and lower limits of the range of possible offset angles for the combing unit 2. Among them, Y=6 is the number of combing units 2 that are equally distributed along the circumference of the channel 4, and X=2 is the ratio of the maximum distance dimension of the combing unit 2 sliding radially along the channel 4 to the initial distance dimension.

[0047] Substituting Y=6 and X=2 into the formula, a specific angle value of 15 degrees can be obtained. This means that when the axis of the combing range of combing unit 2 is set to be offset by 15 degrees relative to the longitudinal axis 3, such as... Figure 3 As shown in Figure (c), the combing range formed by the offset combing unit 2 does not coincide with the combing range of the combing unit 2 as a mirror image of the longitudinal axis 3, which can achieve the theoretically optimal combing coverage.

[0048] like Figure 4 As shown, the combing unit 2, offset by 15 degrees, is placed in a two-dimensional plane coordinate system. All combing units 2 divide the radial range of channel 4 into multiple sectors, which can also be called region angles.

[0049] In the same area corner Inside, the initial position of combing unit 2 is the inner equivalent sector. The position of the combing unit 2 with the maximum sliding distance and the same central angle as the initial position is the outer equivalent sector. The ratio of X also includes the inner chord length of the inner equivalent sector. Outer chord length of the equivalent sector The ratio, or the inner arc length of the equivalent sector. Outer arc length of the equivalent sector The ratio, or the internal equivalent comb size of the internal equivalent sector. External equivalent comb size of the external equivalent sector The ratio of .

[0050] In other embodiments, the ratio of the maximum distance the combing unit 2 slides radially along the channel 4 to the initial distance is set to a value of 1. The number of combing units 2, which are equally divided along the four circumferences of the channel, is six, according to the formula The optimal offset angle setting range of the combing unit 2 can be obtained, that is, the offset angle should be set to 10~20° plus N∙60°; if N is 1, the offset angle should be set to 70~80°.

[0051] The specific implementation process is as follows: The grooming assembly is installed on the pet's dedicated entrance. The motor drives the worm gear to rotate, which in turn drives the worm wheel meshing with it to rotate. Since the worm wheel is connected to the slide plate 12, the rotation of the worm wheel will drive the slide plate 12 to rotate. During the rotation of the slide plate 12, the grooming unit 2 on the slide plate 12 also completes a 15-degree offset setting. At this time, the grooming unit 2 is in its initial position, that is, in the position with the smallest distance from the center of the channel 4, and the inner diameter of the entrance channel 4 formed by the six grooming units 2 on the slide plate 12 is the smallest. At this time, the inner diameter of the channel 4 is smaller than the body size of most pets.

[0052] When a pet enters channel 4 from one end, its body contacting the combing roller 22 pushes the combing unit 2 away from the center of channel 4, stretching the spring. For example... Figure 3 As shown in Figure (a), the combing unit 2 is in its initial position. Due to the 15-degree offset of the combing unit 2, when the combing unit 2 expands under the pressure of the pet, a gap appears in the area of ​​the combing range acting on the pet's body. Figure (b1) shows the combing range when the pet enters the channel 4 and the combing unit 2 expands. The combing roller 22 rolls under the friction of the pet's hair and the agitation of the baffle 23, gently combing and removing loose hair through rolling friction. The fallen hair is collected in the combing seat 21.

[0053] When the pet turns around and exits through passage 4, its body rotates 180 degrees relative to passage 4. On the return journey, the same 15-degree offset grooming unit 2, due to the pet's body turning around, as... Figure 3 As shown, the grooming range of the grooming unit 2 now becomes the gap area when the pet enters the channel 4. Figure (b2) shows the grooming range when the pet leaves the channel 4 and the grooming unit 2 expands. The grooming unit 2 will also adapt to the radial movement according to the pet's body size.

[0054] As a result, after the pet completes one round trip, all major areas of its body are effectively groomed. As shown in Figure (c), due to the scientifically designed offset angle, the grooming areas on the outward and return journeys complement each other on the pet's body surface, greatly reducing blind spots during grooming. The components in this embodiment can automatically adapt to pets of different sizes and fur lengths. The owner can observe the fullness of the grooming seat 21 through the transparent cover 11 for cleaning. For multi-pet households or different grooming preferences, the offset angle of the grooming unit 2 can be finely adjusted via the drive device to change the main grooming areas.

[0055] Example 2 The difference between this embodiment and Embodiment 1 is that a comb tooth strip 24 is fixedly installed on the narrower end of the comb base 21 facing the inner side of the channel 4. This comb tooth strip 24 has comb teeth, all of which are bent in the same direction, forming a consistent arc. The comb teeth are made of a highly elastic silicone material, allowing them to bend and deform under force and return to their original shape after the external force is removed. The comb tooth strips 24 on adjacent comb units 2 are arranged in a crisscross pattern. Specifically, when the comb unit 2 is in its initial position, the length of all comb tooth strips 24 is greater than the length of the narrower end of the comb base 21, and all comb tooth strips 24 will be staggered at a certain angle. Figure 5 As shown, the comb teeth 24 of the six combing units 2 can be configured such that the installation angle of each comb tooth 24 is slightly different, thereby forming two different comb tooth arrays in the circumferential direction, which overlap each other.

[0056] When a pet passes through channel 4, its body comes into contact with the curved, flexible comb teeth. The elasticity of the comb teeth allows them to adapt to the contours of the pet's body and the density of its fur. The comb teeth bend to the same side, allowing them to glide smoothly over the fur as the pet passes through, penetrating deep into the fur layer to remove loose and dead hair, reducing concentrated pulling and irritation to the skin, making it especially suitable for pets with sensitive skin.

[0057] The intersecting arrangement of adjacent comb teeth 24 allows for sufficient combing space when the pet's body squeezes the comb teeth 24, expanding the combing unit 2. This increases the effective working area and contact angle of the comb teeth. This effectively increases the contact area between the comb teeth and the pet's fur during a single pass, improving the efficiency of a single combing session.

[0058] It improves the durability of the combing assembly, reduces failures caused by jamming or wear of rotating parts, and is more cost-effective, making it ideal for mass markets or applications requiring large-scale deployment.

[0059] Example 3 The difference between this embodiment and Embodiment 1 is that the guide holes 13 evenly spaced circumferentially on the slide plate 12 are all strip-shaped holes. The length direction of each guide hole 13 does not point to the central axis of the channel 4, but is offset at an angle relative to the radius of the channel 4. This offset angle ranges from 0 degrees to 90 degrees. Figure 6 As shown, in this embodiment, all six guide holes 13 are offset by 45 degrees. This causes the combing unit 2 installed in the guide holes 13 to have a spiral distribution in space.

[0060] In this embodiment, the rotation of the slide plate 12 is manually adjusted. A protruding lever is fixedly mounted on the circumferential side of the slide plate 12. An arc-shaped lever groove is machined on the side wall of the housing 1, corresponding to the lever's movement trajectory. The lever passes through the lever groove and partially protrudes from the housing 1, forming a handle for the user to operate. Although the arc length of the lever groove limits the rotatable angle range of the slide plate 12, it covers the effective offset angle range required by the combing unit 2, serving as a physical limit and motion guide.

[0061] On the outer surface of the housing 1, adjacent to the dial groove, a scale indicating the offset angle of the combing unit 2 is printed. The 0-degree baseline of the scale corresponds to the symmetrical state of the combing unit 2 based on the longitudinal axis 3, and the scale values ​​precisely correspond to different positions of the dial in the groove. By observing the scale indicated by the tip of the dial, the user can directly read the overall offset angle of the current combing unit 2 layout.

[0062] Because the sliders of all the grooming units 2 are confined within strip-shaped holes with an offset angle of 45 degrees, even when the slide plate 12 is in a fixed position, the projections of these grooming units 2 onto the cross-section of the channel 4 are no longer uniformly radial. When the pet passes through and pushes the grooming units 2 away from the center of the channel 4, the trajectory of each grooming unit 2 is along the direction of its respective strip-shaped hole. Combined with the cylindrical contour of the pet's body, when the grooming unit 2 slides along the offset strip-shaped hole and moves relative to the pet's body surface, its grooming trajectory on the pet's body surface is closer to an oblique line or spiral line, rather than a simple straight line. This is equivalent to increasing the length and coverage area of ​​the grooming path during a single pet passage, effectively making the grooming area form a directional, asymmetrical coverage relative to the pet's body, thus expanding the grooming area.
