Description

Technical Field

[0001] The utility model mainly relates to the technical field of hair removal brushes, and specifically relates to a pet hair removal brush. Background Art

[0002] The number of people keeping pets is increasing day by day, but most pets suffer from hair loss and fur molting. The hair shed by pets usually sticks to home fabrics such as beds, sofas, and carpets. How to clean the hair shed by pets has always been a problem for pet-keeping families.

[0003] Existing pet hair removal brushes are usually used to clean pet hair attached to home textiles. They are generally composed of a handle and a brush head. The brush head is usually provided with a hair removal cloth or soft rubber scraping teeth for rubbing against the surface of home textiles to which pet hair is attached. The fiber bristles or soft rubber brush teeth of the hair removal cloth are used to comb the pet hair off the surface of the home textiles.

[0004] For example, a Chinese patent document (publication number: CN 219165399 U) provides a depilatory brush, but the entire brush head of this type of depilatory brush is stiff and inelastic, so when using the depilatory brush to clean surfaces with concave and convex textures or undulating surfaces, it cannot completely fit, leaving dead corners and affecting the cleaning effect.

[0005] For example, a Chinese patent document (publication number: CN 220630612 U) provides a hair removal brush, which can effectively clean the dead corners on the surface of home textiles. However, since the hair removal brush directly relies on the pressure exerted by the user's hand, the user is prone to hand soreness after use.

[0006] For the above problems, the related technologies do not provide effective solutions. Utility Model Content

[0013] Furthermore, the brush head holder includes a pad, which is located on a side of the brush head holder away from the handle and is used to connect the rack, and the pad is embedded in the rack.

[0014] Furthermore, the brush head bracket also includes a connecting portion, one side of the connecting portion is connected to the handle, and the side away from the handle is connected to the pad, and the thickness of the pad is smaller than the connecting portion; the pad and the rack are secondary injection molded.

[0015] Furthermore, the thickness of the cushion strip on a side close to the brush head support is greater than the thickness of the side away from the brush head support; the width of the cushion strip is 5 mm to 10 mm.

[0016] Furthermore, the brush head bracket is formed with a mounting groove, which is located on a side of the brush head bracket away from the handle and is used to connect the rack, and one side of the rack is embedded in the mounting groove.

[0017] Furthermore, the two opposite sides of the rack in the thickness direction are divided into a first side and a second side; the first side is provided with the scraping teeth, and the scraping teeth are a rotary structure.

[0018] Furthermore, the rack is bent at one side away from the brush head holder, the bending direction is away from the first surface, and the rotation axis of the scraping teeth is perpendicular to the two side surfaces in the thickness direction of the brush head holder.

[0019] Furthermore, a scraper strip is arranged on the second surface, the cross section of the scraper strip is a quadrilateral, the bottom area of ​​the scraper strip is larger than the bottom area of ​​the scraper teeth; the scraper strip extends along the length direction of the rack, and the top of the scraper strip is serrated.

[0020] Furthermore, the handle is detachably connected to the brush head bracket.

[0021] Furthermore, the thickness of the brush head bracket and the rack is less than 15 mm.

[0022] To achieve the above-mentioned purpose, some embodiments of the present application also provide a pet hair removal brush, including a handle, a brush head holder and a rack, one side of the brush head holder is connected to the handle, and the side of the brush head holder facing away from the handle is connected to the rack; the Shore hardness of the rack is 35 to 80 degrees; the rack is formed with scraping teeth, and the scraping tooth height is 1.5 mm to 2.8 mm; the scraping tooth root diameter is 1.2 mm to 3 mm; the scraping teeth are at least arranged on one side in the thickness direction of the rack, and the surface is used to rub the surface of household fabrics; in the width direction of the brush head holder, the surface where the scraping teeth are located exceeds the brush head holder by at least 10 mm; the brush head holder and the rack are both projected along the thickness direction of the brush head holder, and the projection of the brush head holder and the projection of the rack partially overlap.

[0025] The user can easily apply force to the rack through the handle and the brush head holder. The part of the rack that exceeds the brush head holder can be fully deformed. The brush head holder effectively supports the rack, so that the rack can fully fit the surface of the home textiles. The pet hair can be easily scraped or removed from the surface of the home textiles by scraping teeth. Since there are certain gaps on the surface of home textiles such as sofas and beds, users often face cleaning dead corners when cleaning. The design of the brush head holder and the rack that do not completely overlap in the thickness direction of the present application avoids the problem of the overall structure of the hair removal brush being too thick due to the need to match the brush head holder with the rack, so that the brush head holder and the rack are flat as a whole, and users can flexibly insert the hair removal brush into the gaps of home textiles for hair removal.

[0044] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

These terms are mainly intended to better describe the present application and its embodiments, and are not intended to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation. Moreover, in addition to being used to indicate orientation or positional relationships, some of the above terms may also be used to express other meanings. For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0047] As an implementation mode 1 of this embodiment, Figures 1 to 4 As shown, a pet hair removal brush is provided, including a handle 100, a brush head holder 200 and a rack 300. The rack 300 is formed with scraping teeth 310. The scraping teeth 310 are arranged on at least one side of the rack 300 in the thickness direction. The surface is used to rub the surface of the home textile products. The pet hair on the surface of the home textile products is removed by the rack 300 and the scraping teeth 310 thereon.

[0048] The handle 100 and the brush head bracket 200 have a Shore hardness of 95 or more, such as ABS, PP, PC, nylon or metal, etc. The handle 100 and the brush head bracket 200 can be an integral structure, such as integral injection molding, or a split structure. The rack 300 has a Shore hardness of less than 80 and is made of soft rubber materials such as silicone, TPR, TPU, TPE or natural rubber. The surface of such materials usually has a certain degree of stickiness. If a material with a Shore hardness of more than 80 is used, the rack 300 will be too stiff and less sticky, and the hair removal effect will be poor. At the same time, when the scraper teeth 310 are harder, it is easy to scratch the fabric fibers, resulting in damage such as snagging.

[0049] More specifically, the Shore hardness of the rack is 35 to 80 degrees, such as 40, 48, 62 or 75 degrees. If the hardness is lower than 35 degrees, the rack 300 and the scraper teeth 310 thereon are prone to excessive deformation, and the scraper teeth 310 are deformed and tilted, causing the scraper teeth 310 to lose the combing effect on the surface fibers of the fabric, resulting in low operating efficiency.

[0050] Among them, considering that pet hair is short and soft, it is easy to adhere to the surface of home textiles and insert into the inside of fiber products. Therefore, the height of the scraper teeth 310 in this embodiment is greater than 1 mm and less than 5 mm, such as 1 mm, 1.3 mm, 1.6 mm, 2 mm, 2.2 mm, 3.6 mm or 4 mm, but not including 5 mm. Combined with the overall soft and deformable characteristics of the rack 300, the height of the scraper teeth 310 is limited within the above range, so that it can better act on the surface of home textiles.

[0051] Specifically, the scraper teeth 310 are cones or truncated cones, such as cones, pyramids, truncated cones or prisms, so that the scrapers all have the characteristics of a larger cross-sectional area at the root and a smaller cross-sectional area at the top. Compared with the scraper tooth structure that is straight up and down, the scraper teeth 310 of the present application have a large cross-sectional area at the root, which can provide a larger support force for the scraper teeth 310, so that the scraper teeth 310 remain relatively stiff and not easy to fall when they are compressed and the rack 300 moves; the scraper teeth 310 have a small cross-sectional area at the end, which can effectively penetrate into the texture and fluff of the fiber products to comb out / adhere the hair.

[0052] If the scraper teeth 310 are less than 1 mm in height, it is difficult to penetrate between the fibers and effectively comb out the pet hair. A scraper teeth height less than 1 mm can only increase the friction force and is suitable for cleaning human hair on smooth and hard surfaces, so that the hair is accumulated in one place and is easy to clean. If the scraper teeth 310 are greater than or equal to 5 mm in height, pet hair is very easy to entangle with the scraper teeth 310. If the scraper teeth 310 are not removed in time after being entangled, and continue to rub against the surface of the home textiles, it is very easy to cause the scraper teeth 310 to break.

[0053] Specifically, the scraper tooth 310 is a cone or a truncated cone.

[0054] Furthermore, the root diameter of the scraper teeth 310 is 1 mm to 3.5 mm, for example 1 mm, 1.5 mm, 2 mm or 3.2 mm, so that the root of the scraper teeth 310 has a certain strength. If the root of the scraper teeth 310 is too thick, the gap between adjacent scraper teeth 310 will increase, the density of the scraper teeth 310 will decrease, and the hair removal effect will be worse.

[0055] Preferably, the height of the scraper teeth 310 is 1.5 mm to 2.8 mm. Within this numerical range, whether the user is cleaning the hair of a long-haired pet or a short-haired pet, the pet hair is not likely to be tangled with the scraper teeth 310 .

[0056] Furthermore, the root diameter of the scraper teeth is 1.2 mm to 3 mm. Within this numerical range, the scraper teeth are finer and more dense when having a certain strength, and can clean pet hair in a delicate manner.

[0057] Combination Figures 2 to 4As shown, one side of the brush head holder 200 is connected to the handle 100, and the side of the brush head holder 200 away from the handle 100 is connected to the rack 300. The brush head holder 200 and the rack 300 are both projected along the thickness direction of the brush head holder 200, and the projection of the brush head holder 200 and the projection of the rack 300 partially overlap, that is, in the thickness direction of the brush head holder 200, the brush head holder 200 and the rack 300 partially overlap. For example, the brush head holder 200 is embedded in or covers a portion of the rack 300 to provide support for the softer rack 300. At the same time, in the width direction of the brush head holder 200, the rack 300 extends beyond the brush head holder by at least 10 mm, that is, the surface where the scraping teeth are located extends beyond the brush head holder by at least 10 mm. For example, L1 is 10 mm, 15 mm, 19 mm, 20 mm, 22 mm or 36 mm, etc. If the rack 300 is too narrow beyond the brush head holder 200, it is difficult for the rack 300 to be fully deformed, and the surface where the scraping teeth are located is difficult to fully contact with the surface of the home textile products (especially the surface of the home textile products with greater deformation ability).

[0058] Specifically, the thickness of the side of the rack 300 close to the brush head holder 200 is greater than the thickness of the side away from the brush head holder, so that the side of the rack 300 close to the brush head holder 200 has greater strength, thereby increasing the stability of the connection between the rack 300 and the brush head holder 200, and the force applied by the user to the handle 100 and the brush head holder 200 can be effectively transmitted to the rack 300 as a whole. At the same time, the rack 300 is thinner on the side away from the brush head holder 200, and the rack 300 is easier to deform during contact with household fabrics, thereby sticking closely to the surface that needs to be cleaned.

[0059] More specifically, the rack 300 gradually becomes thinner toward the side away from the brush head holder 200 .

[0060] In this way, the user can easily apply force to the rack 300 through the handle 100 and the brush head holder 200. The portion of the rack 300 that exceeds the brush head holder 200 can be fully deformed. The brush head holder 200 effectively supports the rack 300, so that the rack 300 can fully fit with the surface of the home textiles, and the scraping teeth 310 can easily scrape pet hair off the surface of the home textiles.

[0061] Furthermore, since there are certain gaps on the surfaces of home textiles such as sofas and bedside tables, users often face blind spots when cleaning. In the present embodiment, the brush head holder 200 and the rack 300 are not completely overlapped in the thickness direction, thereby avoiding the problem of the overall structure of the hair removal brush being too thick due to the need to match the brush head holder 200 with the rack 300, so that the brush head holder 200 and the rack 300 are flat as a whole, and users can flexibly insert the hair removal brush into the gaps of home textiles for hair removal.

[0062] It is worth noting that the length direction, width direction and thickness direction of the brush head holder 200 and the rack 300 in this example are consistent.

[0063] Preferably, the scraper teeth 310 have a height of 1.8 mm to 2.2 mm. Within this range, the scraper teeth 310 can penetrate into the surface fibers of various fabric products under the action of external force to comb out pet hair and avoid hair entanglement.

[0064] Preferably, in the width direction of the brush head bracket 200, the rack 300 exceeds the brush head bracket by 20 mm to 55 mm. Figure 4 As shown, for example, L1 is 20mm, 25mm, 30mm or 35mm, etc. If it exceeds the brush head holder 200 too much, a part of the rack 300 will be unevenly stressed, and the rack 300 in this area will be difficult to fit the surface of the object, and the scraper 310 will not be able to penetrate between the fibers to comb out the pet hair, resulting in material waste.

[0065] Optionally, in the width direction of the brush head bracket 200, the rack 300 exceeds the brush head bracket by 10 mm to 20 mm. Figure 4 As shown, for example, L1 is 10mm, 11mm, 12mm or 14mm, etc. Within this range, the area where the rack extends beyond the brush head bracket 200 is narrower, which can be suitable for removing hair at the bottom of the narrow gap. The user can press the surface where the scraping teeth are located to the bottom of the narrow gap and brush away the hair at the bottom of the narrow gap with force. However, it is less efficient when cleaning large household fabrics.

[0066] Preferably, the portion of the rack 300 overlapping with the brush head holder 200 in the thickness direction is not covered with the scraping teeth 310. Since the brush head holder 200 provides higher strength to this portion, the scraping teeth 310 of this portion of the rack 300 can be eliminated to save material costs.

[0067] Preferably, the rack 300 is detachably connected to the brush head bracket 200, so that when the rack 300 is worn, the user can replace the rack 300 separately.

[0068] Preferably, the handle 100 is detachably connected to the brush head holder 200, for example, by threading, snapping or plugging. When the rack 300 is severely worn, the user can directly replace the brush head holder 200 and the rack 300 thereon as a whole, which saves time and effort and can further save storage space.

[0069] Preferably, the brush head holder 200 is rotatably connected to the handle 100. For example, a rotating shaft and a limiting structure are provided between the brush head holder 200 and the handle 100. The limiting structure is used to control the rotation angle of the brush head holder 200 so that the angle of the brush head holder 200 relative to the handle 100 is adjustable, which has better flexibility and is convenient for users to clean dead corners of various household fabrics.

[0070] Preferably, the thickness of the brush head bracket 200 and the rack 300 is less than 15 mm, so that the pet hair removal brush can be flexibly used in narrow gaps.

[0071] Optionally, the handle 100 can be a short handle, for example, about 15 cm, for cleaning cat climbing frames, small household fabrics, etc.; it can also be a medium-long handle or a long handle, for example, about 60 cm or 80 cm, for cleaning pet hair on larger household fabrics such as beds. The handle 100 can be a telescopic structure to flexibly adapt to the different needs of users.

[0072] Optionally, the handle 100 may be flat or cylindrical, or may be other structures with axial edges, or may be provided with an anti-skid layer on its surface, so as to increase the friction between the handle 100 and the user's hand, so as to facilitate the user to control the handle 100. To ensure the lightness of the handle 100, the handle 100 may be hollow inside. The handle 100 may be provided with a slot or notch at one end away from the brush head bracket 200, so as to facilitate the user to hang and store the pet hair removal brush.

[0073] The handle 100 may also be provided with a plurality of weight-reducing grooves to ensure the lightness of the handle.

[0074] As the second embodiment of this embodiment, based on the first embodiment, the specific structure of the pet hair removal brush is as follows:

[0075] Combination Figure 5 , 6 As shown in , 7, the brush head holder 200 includes a pad 210, which is located on the side of the brush head holder 200 away from the handle 100 and is used to connect the rack 300. The pad 210 is embedded in the rack 300 to provide support for the rack 300. The pad 210 and the rack 300 are both projected along the thickness direction of the brush head holder 200, and the projection of the pad 210 and the projection of the rack 300 partially overlap. Specifically, the pad 210 is wrapped by the rack 300 at least on both sides in the thickness direction. That is, in the thickness direction of the brush head holder 200, the pad 210 and a part of the rack 300 overlap.

[0076] If the pad 210 is removed and the rack 300 is directly attached to the brush head holder 200, the stability of the connection between the two will be greatly reduced. Since the rack 300 is relatively soft, the rack 300 and its scraping teeth 310 will be pulled by the fibers during operation and receive a large reaction force. The rack 300 can easily be directly peeled off from the brush head holder 200.

[0077] Furthermore, the thickness of the rack 300 on the side close to the pad 210 is greater than the thickness on the side away from the brush head holder. If the thickness of the rack 300 on the side close to the pad 210 is too small, the rack 300 covering the pad 210 will be too thin, and the rack 300 will be easily cut or crushed by the pad during the deformation process.

[0078] Specifically, if Figure 5 As shown, the brush head bracket 200 includes a connecting portion 211 and the above-mentioned pad 210. One side of the connecting portion 211 is connected to the handle 100, and the other side is connected to the pad 210. The connecting portion 211 and the pad 210 can be integrally formed or can be a split structure.

[0079] More specifically, Figure 6 As shown, the connecting portion 211 includes a first matching portion 211a and a second matching portion 211b, the second matching portion 211b is integrally formed with the pad 210, and the first matching portion 211a and the second matching portion 211b are detachably connected, so that the user can replace the pad 210 and the rack 300 thereon as a whole: the user can quickly remove the second matching portion 211b from the first matching portion 211a, and at the same time, remove the pad 210 and the rack 300 synchronously, and then directly install the new second matching portion 211b and the new pad 210 to the first matching portion 211a to form an effective connection between the rack 300 and the brush head holder 200.

[0080] More specifically, the first matching portion 211a forms a groove-shaped structure, the second matching portion 211b is adapted to the first matching portion 211a in shape, the second matching portion 211b can be inserted into the first matching portion 211a, and after the second matching portion 211b is inserted into the first matching portion 211a, the first matching portion 211a and the second matching portion 211b can be locked with each other.

[0081] Preferably, Figures 5 to 7 As shown, the thickness of the pad 210 is smaller than the connecting portion 211, and the pad 210 and the rack 300 are injection molded for the second time. In this way, in view of the thickness difference between the connecting portion 211 and the pad 210, the rubber of the rack 300 is injected into the pad 210, and can come into contact with at least 5 surfaces of the brush head holder 200 after injection molding, forming a tight adhesion with the brush head holder 200, further preventing the user from failing in the connection between the rack 300 and the brush head holder 200 when using the pet hair removal brush, and compared with the ordinary gluing process, the use of secondary injection molding can enhance the adhesion of the rack 300 on the brush head holder 200, thereby extending the service life of the pet hair removal brush.

[0082] Preferably, Figure 7As shown, the width L2 of the pad strip 210 is 2 mm to 10 mm, such as 3 mm, 4 mm or 10 mm. The width of the pad strip 210 is in the range of 2 mm to 5 mm, which is generally suitable for extremely narrow racks, that is, the rack 300 exceeds the brush head bracket by about 10 mm to 20 mm. The width of the pad strip is 5 mm to 10 mm, which is generally suitable for the width of the rack 300 exceeding the brush head bracket by more than 20 mm.

[0083] Further, such as Figure 7 As shown, the thickness of the side of the pad 210 close to the brush head holder 200 is greater than the thickness of the side away from the brush head holder 200. Specifically, the cross-section of the pad 210 perpendicular to the length direction is trapezoidal, which can not only provide a relatively stable support force for the rack 300, but also the side away from the brush head holder 200 can reserve more deformation space for the rack 300. The pad 210 structure can also better adapt to different width ranges of the pad.

[0084] If the pad 210 is less than 2 mm wide, the rack 300 may be easily torn off the pad 210 due to external force, especially when the rack 300 exceeds the brush head holder 200 by a large amount, such as about 40 mm. If the pad 210 is more than 10 mm, since the pad is a thin structure, the wider the pad, the worse the shape strength along the width direction. It lacks sufficient structural support in the width direction, and may break when the user applies pressure to it through the handle. At the same time, the pad 210 that is too wide is easily deformed by the impact force and injection pressure of the soft rubber material of the rack during the secondary injection molding, resulting in uneven pad 210 and curling, which affects the appearance of the product.

[0085] As the third implementation mode of this embodiment, based on the first implementation mode, the specific structure of the pet hair removal brush is as follows:

[0086] Combination Figure 8 , 9 As shown, the brush head bracket 200 is formed with a mounting groove 220, which is located on the side of the brush head bracket 200 away from the handle 100 and is used to connect the rack 300, and one side of the rack 300 is embedded in the mounting groove 220. Specifically, the groove wall of the mounting groove 220 and the rack 300 are both projected along the thickness direction of the brush head bracket 200, and the projection of the groove wall of the mounting groove 220 and the projection of the rack 300 partially overlap. That is, in the thickness direction of the brush head bracket 200, the groove wall of the mounting groove 220 and a part of the rack 300 overlap.

[0087] Preferably, Figure 8As shown, the mounting groove 220 is closed, and the size of the middle or bottom is larger than the size of its opening. The side of the rack 300 is adapted to the structure of the mounting groove 220, further preventing the rack 300 from being torn off from the mounting groove 220 when subjected to external force.

[0088] Preferably, Figure 8 , 9 As shown, the brush head holder 200 is formed with a support plate 221 at the opening of the mounting groove 220, and the extension direction of the support plate 221 is consistent with the width direction of the brush head holder 200. The support plate 221 is at least in contact with the two side surfaces in the thickness direction of the rack 300, and is used to increase the contact area between the brush head holder 200 and the rack 300, prevent the groove wall of the mounting groove 220 from being too thin, and apply shear force to the rack 300 during the deformation of the rack 300. At the same time, the support plate 221 can fully transmit the pressure applied by the user to the rack 300, so that the rack 300 and the scraping teeth 310 thereon are fully deformed, providing effective support force for the rack 300.

[0089] Optional, such as Figure 8 As shown, the brush head holder 200 has two opposite side surfaces along the length direction, at least one of which has an opening, which is located on the side of the mounting groove 220 and is adapted to the shape of the mounting groove 220. The user can insert the rack 300 into the brush head holder 200 from the opening.

[0090] As the fourth embodiment of this embodiment, based on the first, second or third embodiment, the specific structure of the pet hair removal brush is as follows:

[0091] like Fig.10 As shown, the two opposite sides of the rack 300 in the thickness direction are divided into a first side 300a and a second side 300b. The first side 300a and the second side 300b are generally used as the main contact surfaces between the pet hair removal brush and household fabrics. The first side 300a is arranged with scraping teeth 310.

[0092] Specifically, the distance between the roots of the scraping teeth 310 and the adjacent scraping teeth 310 is greater than 0.5 mm, otherwise sharp corners or thin walls will appear on the mold, affecting the strength and life of the mold.

[0093] Further, see Figure 2 As shown, the scraping teeth 310 are arranged in a staggered array, so that the scraping teeth 310 on the rack 300 are arranged more closely, the combing efficiency is doubled, and the brushing effect is further improved.

[0094] Preferably, the top of the scraper tooth 310 is spherical or flat. If the top of the scraper tooth 310 is too sharp, it can penetrate deeper into the fiber but is more susceptible to wear and tear, or even break directly in the fiber.

[0095] Preferably, the maximum size of the top of the scraper tooth 310 is less than 1.2 mm, such as 0.4 mm, 0.6 mm, 0.8 mm or 0.9 mm, etc. In this way, the scraper tooth 310 can more easily penetrate between the fibers of the fiber product, and combined with the material properties of the scraper tooth 310, the surface of the home textile products will not be scratched.

[0096] Preferably, Fig.10 As shown, the cross-sectional area of ​​the scraper tooth 310 parallel to the bottom surface gradually decreases from the root of the scraper tooth 310 to the top of the scraper tooth 310, and its taper is above 0.4 and below 1. For example, the taper is 0.4, 0.45, 0.67, 0.8, 0.9 or 1. When the taper is too small, the scraper tooth 310 is easy to bend from the root. When the taper is too large, the protrusion of the scraper tooth 310 is not obvious, which affects the effect of combing the fibers.

[0097] Preferably, Fig.10 As shown, the rack 300 is bent away from the side of the brush head holder 200, and the bending direction is away from the first surface 300a. The rotation axis of the scraper 310 is perpendicular to the two side surfaces in the thickness direction of the brush head holder 200. This design makes at least part of the structure of the rack 300 arc-shaped. On this basis, the scraper 310 is still oriented in the same direction as the force transmission direction of the brush head holder 200, which reduces the user's use burden, so that the user can use less force to make the scraper 310 penetrate into the fiber products, thereby removing pet hair. When the user uses the pet hair removal brush, it is usually accompanied by the extension and bending of the arm. Relative to the surface of the home textile product, the angle at which the handle 100 is held will change by about 20°. If the above preferred structure is adopted, even if the holding angle of the handle 100 changes by about 20°, the rack 300 can still be kept in contact with the surface of the home textile product, and the scraper 310 can penetrate into the fibers, which is in line with the user's use habits.

[0098] As an optional solution, the second surface 300 b of the rack 300 is arranged with scraping teeth 310 , that is, both the first surface 300 a and the second surface 300 b of the rack 300 are arranged with scraping teeth 310 .

[0099] As an alternative, Fig.10 , 11 As shown, the second surface 300b is provided with a scraper bar 320, the cross section of the scraper bar 320 is a quadrilateral, and the bottom area of ​​the scraper bar 320 is larger than the bottom area of ​​the scraper teeth 310. The scraper bar 320 can strengthen the structural strength of the rack 300. Further, the scraper bar 320 extends along the length direction of the rack 300, and the top of the scraper bar 320 is serrated. Although this structure has a weak cleaning effect on pet hair, it can comb the fiber surface smoothly, which complements the function of the scraper teeth 310.

[0100] In summary of the above-mentioned embodiments, as a method of using the pet hair removal brush in this embodiment, the user needs to hold the handle 100 of the hair removal brush, contact the rack 300 made of soft rubber material with the surface of the object with pet hair, slightly press down and move the hair removal brush along the length direction of the handle 100. At this time, the rack 300 is deformed by force and rubs against the curved surface, and the scraping teeth 310 adhere the hair on the surface of the home textiles to the rack 300.

[0101] The pet hair removal brush in this embodiment can effectively clean pet hair adhered to various corners, gaps and uneven surfaces, saving time and effort.
