Description

Technical Field

[0001] This invention relates to the field of pet products, and in particular to a shaving channel structure and a method for adjusting the channel diameter. Background Technology

[0002] In modern life, with the increasing number of pets, especially domestic cats, severe shedding has become a major problem that cat owners urgently need to solve. Shed cat hair is often scattered throughout the home, easily reducing the happiness of cat owners. To address this, cat grooming products have gradually appeared on the market. Most of these products are in the form of combs, while others are designed as passageways installed in litter boxes, cat beds, and cat doorways to automatically collect hair as the cat passes through. However, in actual use, these passageway products generally have the following problems:

[0003] (i) The shaving roller of a grooming shaving tool generally does not have an automatic spring-back structure. Instead, it uses a reversing plate to make the grooming tool swing with the movement of the cat. Because the reversing plate has a large area, the opening of the entire channel product can easily appear very small. Cats need a long adaptation period during use, and it also affects the shaving efficiency. At the same time, some channel products have fewer shaving teeth and are generally shorter. This is only suitable for some short-haired cats and cannot be used for most pet cats, resulting in poor shaving effect and a limited range of applications.

[0004] (ii) The positions of each shaving tool in the shaving channel are relatively fixed, which results in a relatively fixed channel width. It cannot be adjusted according to the size of the cat, which brings a lot of inconvenience to users and the cost of use is also high. At different growth stages of the pet cat, users need to replace the shaving channel product with different sizes for their use. In addition, for multi-cat families, it is also necessary to purchase multiple shaving channel products of different sizes at the same time. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shaving channel structure that can automatically shave and collect cat hair, improve the user experience, and the channel width is adjustable to accommodate cats of different sizes.

[0006] Another object of the present invention is to provide a method for adjusting the channel diameter of the above-mentioned scraping channel structure.

[0007] The technical solution of this invention is as follows: a shaving channel structure, including a shell, a telescopic mechanism, and multiple shaving devices. The telescopic mechanism includes a support ring, a power component, and multiple shaving device drive components. Each shaving device has a shaving device drive component at its bottom, and each shaving device drive component is connected to the support ring. The power component is mounted on the support ring and connected to each shaving device drive component. The shell covers the support ring and the outer periphery of each shaving device. The support ring serves as a mounting bracket, providing a mounting base for the shaving devices and other components of the telescopic mechanism. The power component provides power and transmission for adjusting the fixed position of the shaving devices in the shaving channel (i.e., adjusting the opening of the shaving channel). The shaving device drive components then drive the shaving devices to move, thereby adjusting the position of the shaving devices in the diameter direction of the support ring. Since the shaving channel is formed by multiple shaving devices connected end-to-end, when the position of each shaving device changes in the diameter direction of the support ring, the diameter of the shaving channel also changes, thus achieving channel diameter adjustment to accommodate pet cats of different sizes. In addition, when the cat squeezes the grooming tool, the grooming tool drive assembly can also provide the grooming tool with a certain stroke for it to move on its own (i.e., the free opening of the fixed position below).

[0008] The shaving drive assembly includes a cooperating transmission rack and transmission gear. One end of the transmission rack is connected to the bottom of the shaving device, and the other end is slidably connected to a support ring. The transmission rack and support ring are slidably connected, and the support ring has a groove in which the transmission rack is fitted. Under the drive of the power assembly, the transmission gear rotates, causing the transmission rack to move, which in turn causes the shaving device mounted on one end of the transmission rack to move accordingly.

[0009] The shaving drive assembly also includes a rack and pinion spring. A through groove is provided on the transmission rack, and the rack and pinion spring is located within the through groove. A connecting part is embedded in the through groove at the bottom of the shaving, and the connecting part is fixed to the through groove by the rack and pinion spring. To ensure more stable sliding of the shaving within the through groove, a fixing screw can be provided on the connecting part. The fixing screw is connected to the connecting part, and the nut of the fixing screw is located outside the through groove to prevent the shaving from falling out of the through groove. When the cat passes by the shaving and squeezes it, the shaving will squeeze the rack and pinion spring and move towards the outer periphery of the support ring. At this time, the transmission rack and transmission gear do not move; only the shaving experiences relative displacement with respect to the transmission rack. The stroke of the rack and pinion spring during this process is the free opening of the shaving when it is in the fixed position.

[0010] As a preferred embodiment, the power assembly includes a first gear ring and a knob assembly. The knob assembly includes a knob part, a first pressing spring, and a knob gear component. The upper end of the knob part is a knob cover, and the lower end of the knob gear component is a knob gear. The lower end of the knob part meshes with the upper end of the knob gear component, and the first pressing spring is also sleeved on the knob gear component.

[0011] The outer side of the first gear ring has external teeth, and the inner side of the first gear ring has internal teeth. The knob gear meshes with the external teeth of the first gear ring, and the transmission gear in the hair removal drive assembly meshes with the internal teeth of the first gear ring. The first gear ring and the support ring are coaxially arranged.

[0012] The inner side of the housing is provided with an inwardly extending mounting groove, the knob part extends from the outside of the housing into the mounting groove, the knob gear part extends from the inside of the housing into the mounting groove, and the pressing spring is located in the mounting groove.

[0013] A first protrusion is provided on the surface of the outer casing below the knob cover, and a first groove is provided on the bottom surface of the knob cover to match the first protrusion. A first positioning groove adapted to the shape of the first protrusion is also distributed in the first groove.

[0014] The knob has a first gear buckle in the middle and a first gear slot on the side wall of the mounting groove of the outer casing. The first gear buckle and the first gear slot cooperate with each other.

[0015] When the power component of the above structure is used, its working principle is as follows: When it is necessary to adjust the opening of the shaving channel (i.e., the fixed position of the shaving tool in the shaving channel), press down the knob cover. At this time, the first pressing spring retracts, the first gear buckle disengages from the first gear slot, and then the knob cover is rotated. The knob part rotates as a whole, driving the knob gear component below it to rotate together. The knob gear at the lower end of the knob gear component drives the first gear ring to rotate. The first gear ring drives the transmission gear in the shaving tool drive component to rotate. The transmission gear drives the transmission rack to move, thereby driving the shaving tool installed at one end of the transmission rack to move as well, thus realizing the adjustment of the opening of the shaving channel. During the rotation of the knob cover, the first protrusion on the outer shell slides along the first groove at the bottom of the knob cover. When it slides to the first positioning groove in the first groove (i.e., the lowest point in the groove), the user will feel a certain jolt, indicating that the operation of rotating from one gear to the adjacent gear has been completed. After the user releases the knob cover, the first gear buckle will enter the corresponding first gear slot, and the first pressing spring will return to its original position.

[0016] As another preferred embodiment, the power assembly includes a second gear ring and a paddle assembly. The inner circumference of the second gear ring is provided with internal teeth. The transmission gear in the shaving drive assembly meshes with the internal teeth of the second gear ring. A fixed connecting post is provided on one side of the outer circumference of the second gear ring. The lower end of the paddle assembly is connected to the fixed connecting post. The second gear ring and the bracket ring are coaxially arranged.

[0017] The toggle assembly includes a toggle body and a second pressing spring. The toggle body is an integral structure, including a head and a rod connected together. The lower part of the rod is embedded in a fixed connecting post on the outer periphery of the second toothed ring. The second pressing spring is provided at the bottom of the rod and is located inside the fixed connecting post.

[0018] The outer shell surface is provided with a toggle slide groove, and the rod part of the toggle body passes through the toggle slide groove and extends into the fixed connecting column;

[0019] Along the outer periphery of the sliding groove of the toggle block, the outer surface of the outer shell is also provided with a second protrusion, and the bottom surface of the head of the toggle block body is provided with a second groove that matches the second protrusion. The second groove is also provided with a second positioning groove that matches the shape of the second protrusion.

[0020] The lever body of the lever body is also provided with a second position buckle, and the bottom surface of the outer shell is provided with a second position slot. The second position buckle and the second position slot cooperate with each other.

[0021] When using the power assembly described above, its working principle is as follows: When it is necessary to adjust the opening of the shaving channel (i.e., the fixed position of the shaving tool in the shaving channel), press down on the head of the dial block body. At this time, the second pressing spring contracts, the second gear buckle disengages from the second gear slot, and then the dial block body is moved along the dial block slide groove. The dial block body drives the second gear ring to rotate through the fixed connecting post on the outer circumference of the second gear ring. The second gear ring drives the transmission gear in the shaving tool drive assembly to rotate, and the transmission gear drives the transmission rack to move, thereby driving the shaving tool installed at one end of the transmission rack to move as well, thus realizing the adjustment of the opening of the shaving channel. During the process of moving the dial block body, the second protrusion on the outer shell slides in the second groove on the bottom surface of the dial block body head. When it slides to the second positioning groove in the second groove (i.e., the lowest point in the second groove), the user will feel a certain jerking sensation, indicating that the operation of rotating from one gear to the adjacent gear has been completed. After the user releases the dial block body, the second gear buckle will enter the corresponding second gear slot, and the second pressing spring will return to its original position.

[0022] The grooming device includes a hair storage bin, a grooming roller, an end connecting assembly, a hair collecting brush, a hair collecting brush power assembly, and a hair collecting brush pusher. The grooming roller is located at the bottom of the hair storage bin. One end of the grooming roller is connected to the hair storage bin via the hair collecting brush pusher, and the other end of the grooming roller is connected to the hair storage bin via the end connecting assembly. A hair collecting brush is also located at the bottom of the hair storage bin, distributed on both sides of the grooming roller. The hair collecting brush power assembly is installed inside the hair collecting brush pusher and extends into the grooming roller. Soft teeth are distributed on the cylindrical surface of the grooming roller. When a cat passes by, it pushes the grooming roller to rotate. The grooming roller combs the cat's fur and provides a certain amount of pressure through the soft teeth distributed on its cylindrical surface, achieving a grooming effect while also increasing the massage experience and improving the cat's comfort during use. The combed cat fur enters the hair storage bin as the grooming roller rotates, and when it passes the hair collecting brush, it is swept off and stored in the hair storage bin. The two ends of the scraping roller are respectively installed at the bottom of the hair storage bin via the hair collection brush push part and the end connection assembly, and the scraping roller can rotate relative to the hair storage bin.

[0023] The wool storage bin includes a bin body, a top cover, a first mounting end, and a second mounting end. The top cover covers the top of the bin body, and the first and second mounting ends are located at opposite ends of the lower part of the bin body. The two ends of the shaving roller are respectively connected to the first mounting end and the second mounting end.

[0024] The first mounting end is provided with a slide rail for the brush pusher, a slide rail for the brush power shaft, and a mounting through hole for the scraping roller. From the outer periphery to the center, the slide rail for the brush pusher, the slide rail for the brush power shaft, and the mounting through hole for the scraping roller are distributed in sequence. The mounting through hole for the scraping roller is used for mounting the scraping roller shaft. The slide rail for the brush power shaft provides guidance and limiting for the movement of the brush power shaft. The slide rail for the brush pusher provides guidance and limiting for the movement of the brush pusher.

[0025] The brush pusher is located on the outside of the first mounting end. The side of the brush pusher that connects with the first mounting end is provided with a positioning shaft, a magnetic protrusion, a brush power shaft sliding groove and a third positioning groove. The positioning shaft is located in the middle and is connected to the scraping roller after passing through the scraping roller mounting through hole on the first mounting end.

[0026] The hair collection brush power assembly includes a hair collection brush power shaft and a preload spring. The end of the hair collection brush power shaft is provided with a spherical protrusion, and the preload spring is sleeved on the hair collection brush power shaft. On the hair collection brush pushing part, a hair collection brush power shaft sliding groove is provided on the outer side of the positioning shaft, and a positioning groove is provided in the middle of the hair collection brush power shaft sliding groove. The spherical protrusion at the end of the hair collection brush power shaft cooperates with the hair collection brush power shaft sliding groove and the third positioning groove. After passing through the hair collection brush power shaft slide rail on the first mounting end, the hair collection brush power shaft extends into the scraping roller.

[0027] In the brush-collecting pusher section, a magnetic protrusion is located on the outer periphery of the sliding groove of the brush-collecting drive shaft. The magnetic protrusion passes through the slide rail of the brush-collecting pusher section on the first mounting end and connects to the brush-collecting brush. The magnetic protrusion is magnetically attracted to the side of the brush-collecting brush, ensuring that the two slide relative to each other without separating, thus ensuring that the brush is suitable for different angles when the brush is installed in the brush-collecting channel.

[0028] The second mounting end is provided with a fixing bolt positioning hole and a first fixing position for a torsion spring. The end connection assembly includes a fixing bolt and a torsion spring. The shaving roller is mounted on the fixing bolt positioning hole on the second mounting end via the fixing bolt. The shaving roller is also provided with a second fixing position for the torsion spring, and the torsion spring is sleeved on the fixing bolt. The two ends of the torsion spring are respectively connected to the first fixing position and the second fixing position. The shaving roller can rotate relative to the fixing bolt and the second mounting end. The torsion spring provides a certain preload force, and after the cat passes by, the torsion spring drives the shaving roller to return to its original position. In addition, the shaving roller is also provided with a shaving roller limiting block, and the second mounting end is also provided with a shaving roller limiting slide rail that cooperates with the shaving roller limiting block. The two cooperate to limit the rotation angle of the shaving roller. In addition, the second mounting end is provided with a hair collecting brush limiting component. The number of hair collecting brush limiting components is equal to the number of hair collecting brushes, and the position of the hair collecting brush limiting components is also adapted to the position of the hair collecting brush end on the second mounting end. When the brush on one side of the scraping roller rotates, the brush on the other side will not rotate due to the brush limiting component.

[0029] The soft teeth on the shaving roller include long soft teeth and short soft teeth. Short soft teeth are distributed in the middle of the side of the cylindrical surface of the shaving roller that exposes the bottom of the hair storage compartment, while long soft teeth are distributed on both sides of the short soft teeth. The heads of both the long and short soft teeth are spherical. The length of the long soft teeth is d1, where 2mm ≤ d1 ≤ 15mm; the length of the short soft teeth is d2, where d2 ≤ 2mm. The long soft teeth primarily perform the shaving function, while the short soft teeth increase the contact area between the shaving roller and the cat, providing greater friction to drive the shaving roller's movement.

[0030] In the hair collection brush, the end that connects to the first mounting end is a magnetic area, which magnetically attracts the magnetic protrusion, ensuring that the two only slide relative to each other without separating. This guarantees that the hair remover can be installed at different angles in the hair removal channel. The middle area of ​​the hair collection brush is composed of dense, relatively stiff fine bristles, allowing the long teeth of the hair removal brush to pass through easily, while intercepting loose cat hair on the long teeth and leaving it in the hair storage compartment.

[0031] This invention provides a method for adjusting the channel diameter of the aforementioned shaving channel structure. The user operates the power component in the telescopic mechanism, which drives the synchronous movement of each shaving drive component. Each shaving drive component then moves its corresponding shaving along the diameter direction of the support ring, thereby adjusting the channel diameter of the shaving channel formed between the shavings. The specific operation methods are as follows:

[0032] (I) When the power unit uses the knob mode, when it is necessary to adjust the gear (i.e., the opening of the shaving channel), press down on the knob cover. At this time, the first pressing spring retracts, the first gear latch disengages from the first gear slot, and then the knob cover is rotated. The knob part rotates as a whole, driving the knob gear component below it to rotate together. The knob gear at the lower end of the knob gear component drives the first gear ring to rotate. The first gear ring drives the transmission gear in the shaving drive component to rotate. The transmission gear drives the transmission rack to move, thereby driving the shaving device installed at one end of the transmission rack to move as well, thus realizing the adjustment of the opening of the shaving channel. During the rotation of the knob cover, the first protrusion on the first outer shell slides along the first groove at the bottom of the knob cover. When it slides to the first positioning groove (i.e., the lowest point in the groove) in the first groove, the user will feel a certain jerking sensation, indicating that the operation of rotating from one gear to the adjacent gear has been completed. After the user releases the knob cover, the first gear latch will enter the corresponding first gear slot, and the first pressing spring will return to its original position.

[0033] After adjusting the settings to suit your cat's size, when the cat enters the grooming channel from the front, the pressure exerted by the grooming clippers on different parts of the cat will vary depending on the direction. As the cat presses the clippers, they move outwards, compressing the rack and pinion spring inside the drive rack. The compression stroke of the rack and pinion spring determines the automatic opening degree of the fixed setting. Within the same grooming channel, different clippers have the same free opening degree at each setting.

[0034] (II) When the power assembly uses the toggle mode, when it is necessary to adjust the gear (i.e., the opening of the shaving channel), press down on the head of the toggle body. At this time, the second pressing spring retracts, the second gear buckle disengages from the second gear slot, and then the toggle body is moved along the toggle slide. The toggle body drives the second gear ring to rotate through the fixed connecting post on the outer periphery of the second gear ring. The second gear ring drives the transmission gear in the shaving drive assembly to rotate, and the transmission gear drives the transmission rack to move, thereby driving the shaving device installed at one end of the transmission rack to move as well, thus realizing the adjustment of the opening of the shaving channel. During the process of moving the toggle body, the second protrusion on the second outer shell slides in the second groove on the bottom surface of the toggle body head. When it slides to the second positioning groove (i.e., the lowest point in the second groove) in the second groove, the user will feel a certain jerking sensation, indicating that the operation of rotating from one gear to the adjacent gear has been completed. After the user releases the toggle body, the second gear buckle will enter the corresponding second gear slot, and the second pressing spring will return to its original position.

[0035] After adjusting the settings to suit your cat's size, when the cat enters the grooming channel from the front, the pressure exerted by the grooming clippers on different parts of the cat will vary depending on the direction. As the cat presses the clippers, they move outwards, compressing the rack and pinion spring inside the drive rack. The compression stroke of the rack and pinion spring determines the automatic opening degree of the fixed setting. Within the same grooming channel, different clippers have the same free opening degree at each setting.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] This shaving channel structure is easy to operate and can be quickly contracted or expanded to accommodate pets of different sizes, thus expanding the application range of the product and reducing user costs. Simultaneously, this shaving channel structure automatically shaves and collects cat hair, reducing the frequency and time users need to groom their cats, saving time and improving the user experience. Furthermore, it achieves essentially the same shaving effect for cats of varying fur lengths, making it widely applicable and possessing a promising market prospect.

[0038] In this shaving channel structure, the telescopic mechanism not only allows for the adjustment of the fixed position of the shaving tool to actively expand the shaving channel, but also allows for a certain stroke displacement of the shaving tool when it is squeezed, thus passively expanding the shaving channel. This makes it suitable for cats of various sizes. At the same time, it provides a certain amount of pre-pressure when the cat passes through the shaving channel, increasing the cat's comfort while also relatively increasing the shaving force and improving shaving efficiency.

[0039] In this grooming channel structure, the coordinated operation of the grooming roller and the hair-collecting brush ensures that almost all cat hair enters the hair storage bin, resulting in excellent hair collection. The grooming roller utilizes a torsion spring for rotation, simplifying the reversal process and making the entrance to the grooming channel larger, reducing fear for cats and increasing enjoyment. As the cat passes through the grooming channel, the soft teeth on the grooming roller provide pressure, increasing comfort. Users can also replace the grooming roller with different lengths of soft teeth to accommodate cats with varying fur lengths, offering flexibility and convenience. Attached Figure Description

Detailed Implementation

[0061] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0062] Example 1

[0063] This embodiment provides a scraping channel structure and a method for directly adjusting the channel.

[0064] like Figures 1 to 3As shown, the shaving channel structure includes a housing 3, a telescopic mechanism, and multiple shaving blades 1. These blades are connected end-to-end to form a shaving channel 2. The telescopic mechanism includes a support ring 4, a power component, and multiple shaving blade drive components. Each shaving blade has a drive component at its bottom, and each drive component is connected to the support ring. The power component is mounted on the support ring and connected to each drive component. The housing covers the support ring and the outer periphery of each shaving blade. The support ring serves as a mounting bracket, providing a base for the shaving blades and other components of the telescopic mechanism. The power component provides power and transmission for adjusting the fixed position of the shaving blades within the shaving channel (i.e., adjusting the opening of the shaving channel). The drive components then move the shaving blades, thus adjusting their position in the diameter direction of the support ring. Since the shaving channel is formed by multiple shaving blades connected end-to-end, changes in the position of each shaving blade in the diameter direction of the support ring result in changes in the diameter of the shaving channel, thereby adjusting the channel diameter to accommodate cats of different sizes. In addition, when the cat squeezes the grooming tool, the grooming tool drive assembly can also provide the grooming tool with a certain stroke for it to move on its own (i.e., the free opening of the fixed position below).

[0065] The shaving drive assembly includes a mating rack 5 and a drive gear 6. One end of the rack is connected to the bottom of the shaving device, and the other end is slidably connected to a support ring. The rack and support ring are slidably connected, and the support ring has a groove 4-1 in which the rack is fitted. Driven by the power assembly, the drive gear rotates, causing the rack to move, which in turn moves the shaving device mounted on one end of the rack. Figure 6 or Figure 7 As shown, the shaving drive assembly also includes a rack and pinion spring 7. A through groove 5-1 is provided on the transmission rack, and the rack and pinion spring is located within the through groove. A connecting part 1-1, embedded in the through groove, is located at the bottom of the shaving. The connecting part is fixed to the through groove by the rack and pinion spring. To ensure more stable sliding of the shaving within the through groove, a fixing screw 8 can be provided on the connecting part. The fixing screw is connected to the connecting part via a washer 9, and the nut of the fixing screw is located outside the through groove to prevent the shaving from falling out of the through groove. When the cat passes by the shaving and squeezes it, the shaving will squeeze the rack and pinion spring and move towards the outer periphery of the support ring. At this time, the transmission rack and transmission gear do not move; only the shaving experiences relative displacement with respect to the transmission rack. The stroke of the rack and pinion spring during this process is the free opening of the shaving when it is in the fixed position.

[0066] In this embodiment, the power assembly includes a first gear ring 10 and a knob assembly. The knob assembly includes a knob part 11, a first pressing spring 12, and a knob gear 13. The upper end of the knob part is a knob cover 11-1, and the lower end of the knob gear 13-1 is a knob gear 13-1. The lower end of the knob part meshes with the upper end of the knob gear 13-1. The first pressing spring is also sleeved on the knob gear 13-1. The outer side of the circumference of the first gear ring is provided with external teeth, and the inner side of the circumference of the first gear ring is provided with internal teeth. The knob gear meshes with the external teeth of the first gear ring. The transmission gear in the shaving drive assembly meshes with the internal teeth of the first gear ring. The first gear ring and the support ring are coaxially arranged.

[0067] like Figure 3 or Figure 4 As shown, the inner side of the outer casing has an inwardly extending mounting groove 3-1. The knob extends from the outer side of the outer casing into the mounting groove, the knob gear extends from the inner side of the outer casing into the mounting groove, and the pressing spring is located in the mounting groove. Figure 4 or Figure 5 As shown, a first protrusion 14 is provided on the surface of the outer casing below the knob cover. The bottom surface of the knob cover is provided with a first groove 15 that mates with the first protrusion. The first groove is also provided with first positioning grooves 16 that are adapted to the shape of the first protrusion. A first position latch 17 is provided in the middle of the knob part, and a first position slot 18 is provided on the side wall of the mounting groove of the outer casing. The first position latch mates with the first position slot.

[0068] like Figures 8 to 10 As shown, the hair removal device includes a hair storage bin 19, a hair removal roller 20, an end connecting assembly (including a fixing bolt 21 and a torsion spring 22), a hair collection brush 23, a hair collection brush power assembly (including a hair collection brush power shaft 24 and a preload spring 24), and a hair collection brush pushing part 26. The hair removal roller is located at the bottom of the hair storage bin. One end of the hair removal roller is connected to the hair storage bin through the hair collection brush pushing part, and the other end of the hair removal roller is connected to the hair storage bin through the end connecting assembly. A hair collection brush is also provided at the bottom of the hair storage bin. The hair collection brush is distributed on both sides of the hair removal roller. The hair collection brush power assembly is installed inside the hair collection brush pushing part and extends into the hair removal roller. Soft teeth are distributed on the cylindrical surface of the hair removal roller. As the cat walks by, it pushes the grooming roller to rotate. The roller, with its soft teeth distributed on its cylindrical surface, combs the cat's fur and provides a certain amount of pressure, achieving a grooming effect while also adding a massage experience, improving the cat's comfort during use. The combed-off cat hair enters the hair collection bin as the roller rotates, and is then swept off and stored in the bin by the hair collection brush. The two ends of the grooming roller are respectively mounted to the bottom of the hair collection bin via a hair collection brush pusher and an end connecting assembly, allowing the roller to rotate relative to the bin.

[0069] like Figure 8 or Figure 11As shown, the hair storage bin includes a bin body 19-1, a top cover 19-2, a first mounting end 19-3, and a second mounting end 19-4. The top cover covers the top of the bin body. The first and second mounting ends are located at opposite ends of the lower part of the bin body. The two ends of the scraping roller are connected to the first and second mounting ends, respectively. The first mounting end is provided with a hair collecting brush pusher slide rail 19-5, a hair collecting brush power shaft slide rail 19-6, and a scraping roller mounting through hole 19-7. From the outer periphery to the center, the hair collecting brush pusher slide rail, the hair collecting brush power shaft slide rail, and the scraping roller mounting through hole are distributed sequentially. Among them, the scraping roller mounting through hole is used for mounting the scraping roller shaft, the hair collecting brush power shaft slide rail provides guidance and limiting function for the movement of the hair collecting brush power shaft, and the hair collecting brush pusher slide rail provides guidance and limiting function for the movement of the hair collecting brush pusher. The hair collecting brush pusher is located on the outside of the first mounting end, as shown in the figure. Figure 12 As shown, the side of the brush pusher that connects to the first mounting part is provided with a positioning shaft 26-1, a magnetic protrusion 26-2, a brush power shaft sliding groove 26-3, and a third positioning groove 26-4. The positioning shaft is located in the middle and passes through the scraping roller mounting through hole on the first mounting end to connect with the scraping roller. The brush power assembly includes a brush power shaft and a preload spring. The end of the brush power shaft is provided with a spherical protrusion 24-1 (e.g., ...). Figure 8 As shown), a preload spring is sleeved on the hair-collecting brush drive shaft; on the hair-collecting brush pushing part, a hair-collecting brush drive shaft sliding groove is provided on the outer side of the positioning shaft, and a positioning groove is provided in the middle of the hair-collecting brush drive shaft sliding groove. The spherical protrusion at the end of the hair-collecting brush drive shaft cooperates with the hair-collecting brush drive shaft sliding groove and the third positioning groove. After passing through the hair-collecting brush drive shaft slide rail on the first mounting end, the hair-collecting brush drive shaft extends into the scraping roller (as shown). Figure 9 (As shown). In the brush pushing part, a magnetic protrusion is provided on the outer periphery of the sliding groove of the brush collecting power shaft. The magnetic protrusion passes through the slide rail of the brush collecting pushing part on the first mounting end and connects with the brush collecting part. The magnetic protrusion connects with the side of the brush collecting part (as shown). Figure 14 The magnetic attraction areas 23-1 shown are magnetically attracted to each other, ensuring that the two slide relative to each other without separating, thus ensuring that the shaving tool is applicable at different angles when installed in the shaving channel.

[0070] like Figure 11 As shown, the second mounting end is provided with a fixing bolt positioning hole 19-1 and a torsion spring first fixing position 19-10; the end connection assembly includes a fixing bolt and a torsion spring, and the scraping roller is mounted to the fixing bolt positioning hole on the second mounting end through the fixing bolt, and the scraping roller is also provided with a torsion spring second fixing position 20-1 (as shown). Figure 13 As shown), the torsion spring is sleeved on the fixing bolt, and the two ends of the torsion spring are respectively connected to the first fixing position and the second fixing position of the torsion spring (as shown). Figure 9(As shown). The shaving roller can rotate relative to the fixing bolt and the second mounting end. A torsion spring provides a certain preload, and after the cat passes by, the torsion spring drives the shaving roller to return to its original position. In addition, the shaving roller is also equipped with a shaving roller limit block 20-2 and a fixing bolt mounting hole 20-3 (as shown). Figure 13 As shown), the second mounting end is also provided with a scraping roller limiting slide rail 19-11 (as shown) that cooperates with the scraping roller limiting block. Figure 11 As shown), the two work together to limit the rotation angle of the shaving roller (e.g. Figure 9 (As shown). Furthermore, a brush-collecting limiting component 19-8 is provided on the second mounting end. The number of brush-collecting limiting components is equal to the number of brushes, and the positions of the brush-collecting limiting components are adapted to the positions of the brush ends on the second mounting end. When the brush-collecting component on one side of the scraping roller rotates, the brush-collecting component on the other side will not rotate accordingly.

[0071] like Figure 8 As shown in Figure 10, the soft teeth on the shaving roller include long soft teeth 20-4 and short soft teeth 20-5. Short soft teeth are distributed in the middle of one side of the cylindrical surface of the shaving roller, which exposes the bottom of the hair storage compartment, while long soft teeth are distributed on both sides of the short soft teeth. The long soft teeth primarily perform the shaving function, while the short soft teeth increase the contact area between the shaving roller and the cat, providing greater friction to drive the shaving roller's movement. The heads of both the long and short soft teeth are spherical, providing a massage function. The length of the long soft teeth is d1, 2mm≤d1≤15mm; the length of the short soft teeth is d2, d2≤2mm. The long soft teeth on the shaving roller are axially symmetrical, with N rows of long soft teeth on one side, where 1≤N≤10, and the angular spacing of each row of soft teeth is 5~45°. The overall rotation angle of the shaving roller is y (where y is the angle between the teeth on each side and the angle between the teeth on each side). Figure 3 The shaving roller shown is in its initial position. The angles at which the shaving roller reaches its limit position are the same when it rotates clockwise and counterclockwise. The sum of the two rotation angles is y), and the range of this angle is limited to 60°≤y≤200°.

[0072] like Figure 14 As shown, in the hair collection brush, the end of the hair collection brush that connects to the first mounting end is a magnetic attraction area 5-1, which magnetically attracts the magnetic protrusion, ensuring that the two only slide relative to each other without separating, thus ensuring that the hair scraper can be installed at different angles in the hair scraping channel. The middle area of ​​the hair collection brush is composed of dense, relatively stiff fine bristles, forming a soft hair collection brush 5-2, which allows the long hair scraping teeth to pass through easily, but can intercept the cat's loose hair on the long teeth, leaving the loose hair in the hair storage compartment.

[0073] In this embodiment, the method for adjusting the channel diameter of the aforementioned shaving channel structure involves the user operating the power component in the telescopic mechanism. The power component drives the synchronous movement of each shaving drive component, which in turn moves the corresponding shaving device along the diameter direction of the support ring, thereby adjusting the channel diameter of the shaving channel formed between the shaving devices. The specific operation is as follows:

[0074] When adjusting the gear (i.e., the opening of the shaving channel), press down on the knob cover. The first pressing spring retracts, disengaging the first gear latch from the first gear slot. Then, rotate the knob cover. The knob rotates as a whole, causing the knob gear component below it to rotate as well. The knob gear at the lower end of the knob gear component drives the first gear ring to rotate. The first gear ring drives the transmission gear in the shaving drive assembly to rotate. The transmission gear drives the transmission rack to move, which in turn moves the shaving device mounted on one end of the transmission rack, thus adjusting the opening of the shaving channel. During the rotation of the knob cover, the first protrusion on the first outer shell slides along the first groove at the bottom of the knob cover. When it slides to the first positioning groove (i.e., the lowest point in the groove), the user will feel a slight jolt, indicating that the operation of rotating from one gear to the adjacent gear has been completed. After the user releases the knob cover, the first gear latch will enter the corresponding first gear slot, and the first pressing spring will return to its original position.

[0075] After adjusting the settings to suit your cat's size, when the cat enters the grooming channel from the front, the pressure exerted by the grooming clippers on different parts of the cat will vary depending on the direction. As the cat presses the clippers, they move outwards, compressing the rack and pinion spring inside the drive rack. The compression stroke of the rack and pinion spring determines the automatic opening degree of the fixed setting. Within the same grooming channel, different clippers have the same free opening degree at each setting.

[0076] Meanwhile, when a pet cat passes through the grooming tunnel, the working principle of a single grooming tool is as follows: Figure 10The relative positions of the components shown are used as the initial positions. When the cat passes the groomer from left to right, the cat comes into contact with the soft teeth on the grooming roller, causing the grooming roller to rotate counterclockwise. At the same time, the cat hair on the cat's body is scraped off and stuck to the soft teeth. The torsion spring has a certain preload. The initial position of the spherical protrusion at the front of the bristle-collecting brush drive shaft is located in the positioning groove in the middle of the sliding groove of the bristle-collecting brush drive shaft. The scraping roller drives the bristle-collecting brush drive shaft to rotate together. When the bristle-collecting brush drive shaft rotates, the resistance also causes the bristle-collecting brush push part to rotate counterclockwise. At this time, the rotation angle of the bristle-collecting brush push part on one side is β, 10°≤β≤45°. The magnetic protrusion on the bristle-collecting brush push part will simultaneously push the bristle-collecting brush on the right side to rotate clockwise around its side axis 5-3, allowing the scraping soft teeth on the scraping roller on the same side to pass smoothly. The bristle-collecting brush limiting component ensures that the bristle-collecting brush on the left side will not rotate counterclockwise due to loss of support. When the bristle-collecting brush push part reaches its limit position, the spherical protrusion at the front end of the bristle-collecting brush drive shaft will slide out of the positioning groove and slide in the sliding groove of the bristle-collecting brush drive shaft to ensure that the scraping roller continues to rotate. The sliding angle of the bristle-collecting brush drive shaft on one side in the sliding groove of the bristle-collecting brush drive shaft is a, a≥y / 2-β. As the cat passes through, when the shaving roller reaches its limit position, its rotation angle remains unchanged, allowing the cat to continue passing and shaving. Once the cat has completely passed the groomer, the torsion spring releases its force, causing the shaving roller to rotate back a certain angle. The spherical protrusion in front of the hair collection brush drive shaft also returns to its positioning groove. The hair collection brush drive shaft then drives the hair collection brush push component to rotate. Due to magnetic attraction, the hair collection brush also rotates, and eventually, the shaving roller, hair collection brush, and hair collection brush push component all return to their initial positions. When the cat moves from right to left, the principle is the same. However, when the cat has completely passed the groomer from right to left, as the torsion spring rotates, the cat hair left on the left shaving teeth of the shaving roller in the previous stage is blocked by the hair collection brush and remains in the hair storage compartment.

[0077] Example 2

[0078] This embodiment provides a scraping channel structure and a method for directly adjusting the channel.

[0079] The difference between the scraping channel structure and that in Embodiment 1 lies in the structure of the power assembly. In this embodiment, as shown... Figure 15 or Figure 17As shown, the power assembly includes a second gear ring 27 and a paddle assembly. The inner circumference of the second gear ring has internal teeth, and the transmission gear in the shaving drive assembly meshes with the internal teeth of the second gear ring. A fixed connecting post 27-1 is provided on one side of the outer circumference of the second gear ring. The lower end of the paddle assembly is connected to the fixed connecting post. The second gear ring and the support ring are coaxially arranged. The paddle assembly includes a paddle body 28 and a second pressing spring 29. The paddle body is an integral structure, including a connected head and a rod. The lower part of the rod is embedded in the fixed connecting post on the outer circumference of the second gear ring, and the second pressing spring is provided at the bottom of the rod, located inside the fixed connecting post.

[0080] Furthermore, the surface of the outer casing 3 is provided with a toggle slide groove 30, and the rod of the toggle body passes through the toggle slide groove and extends into the fixed connecting post. Along the outer periphery of the toggle slide groove, the surface of the outer casing is also provided with a second protrusion 31, and the bottom surface of the head of the toggle body is provided with a second groove 32 that mates with the second protrusion. The second groove is also provided with a second positioning groove (not shown in the figure) that is adapted to the shape of the second protrusion; wherein, the second positioning groove is a groove further opened in the second groove, and the depth of the second positioning groove is greater than the depth of the second groove. The rod of the toggle body is also provided with a second position buckle 33, and the bottom surface of the outer casing is provided with a second position groove 34, and the second position buckle mates with the second position groove.

[0081] In this embodiment, the method for adjusting the channel diameter of the aforementioned shaving channel structure involves the user operating the power component in the telescopic mechanism. The power component drives the synchronous movement of each shaving drive component, which in turn moves the corresponding shaving device along the diameter direction of the support ring, thereby adjusting the channel diameter of the shaving channel formed between the shaving devices. The specific operation is as follows:

[0082] When the power unit is in paddle mode, to adjust the gear (i.e., the opening of the shaving channel), press down on the head of the paddle body. The second pressing spring retracts, disengaging the second gear latch from the second gear slot. Then, move the paddle body along the paddle slide. The paddle body drives the second gear ring to rotate via the fixed connecting post on the outer circumference of the second gear ring. The second gear ring drives the transmission gear in the shaving drive assembly to rotate, which in turn moves the transmission rack, causing the shaving device mounted on one end of the rack to move as well, thus adjusting the opening of the shaving channel. During the movement of the paddle body, the second protrusion on the second outer shell slides within the second groove on the bottom surface of the paddle body head. When it slides to the second positioning groove (i.e., the lowest point in the second groove), the user will feel a slight jolt, indicating that the operation of shifting from one gear to an adjacent gear has been completed. After the user releases the paddle body, the second gear latch enters the corresponding second gear slot, and the second pressing spring returns to its original position.

[0083] After adjusting the settings to suit your cat's size, when the cat enters the grooming channel from the front, the pressure exerted by the grooming clippers on different parts of the cat will vary depending on the direction. As the cat presses the clippers, they move outwards, compressing the rack and pinion spring inside the drive rack. The compression stroke of the rack and pinion spring determines the automatic opening degree of the fixed setting. Within the same grooming channel, different clippers have the same free opening degree at each setting.

[0084] Meanwhile, when a pet cat passes through the shaving channel, the working principle of a single shaving tool is the same as in Example 1.

[0085] As described above, the present invention can be well implemented.
