[0044] Please see Figures 1 to 13This embodiment provides a pet brush with a quick-release brush head 1, including a brush head 1, a crank 2, and a replacement brush head 3. The brush head 1 includes a housing 11 and a connector 12. The housing 11 is provided with a receiving cavity 111 and a sliding cavity, which are interconnected. The connector 12 is slidably disposed in the sliding cavity. The crank 2 includes a rotating end 21, a connecting end 22, and a driving end 23. The rotating end 21 is rotatably connected to the housing 11, and the connecting end 22 is connected to the connector 12. The driving end 23 is connected to the rotating end 21 and the connecting end 22 to drive the connecting end 22 to rotate around the rotating end 21. The replacement brush head 3 includes a replacement part 31 and a scraper 32. The scraper 32 is slidably connected to the replacement part 31. The replacement part 31 is adapted to the receiving cavity 111 and is detachably connected to the housing 11.

[0045] The housing 11 is made of high-strength plastic or lightweight alloy material, which has good durability and impact resistance.

[0046] The connector 12 can be a rod-shaped or block-shaped structure, and the material can be wear-resistant engineering plastic or metal. The connector 12 is connected to the crank 2 and can move vertically under the action of the crank 2.

[0047] The sliding cavity is a channel opened inside the housing 11. The cross-sectional shape of the sliding cavity matches the connecting member 12 and can be circular, square or rectangular.

[0048] Specifically, the inner wall of the sliding chamber is provided with a guide groove in the vertical direction, and the two sides of the connector 12 are provided with protrusions. The protrusions are adapted to the guide groove to constrain the movement of the connector 12 in the horizontal direction, and at the same time guide the connector 12 to move in the vertical direction, further ensuring the linearity and stability of the sliding of the connector 12, and preventing the connector 12 from deviating or rotating during the sliding process.

[0049] The accommodating cavity 111 is a recessed structure formed by an inward indentation on the housing 11, used to accommodate the replacement brush head 3.

[0050] The crank 2 is a component integrally molded from metal or high-strength plastic, with an overall bent structure. The rotating end 21 has an outwardly extending columnar structure, and a shaft hole adapted to the columnar structure on the rotating end 21 is provided at a corresponding position on the housing 11. By accommodating the columnar structure on the rotating end 21 in the shaft hole, a rotatable connection with the housing 11 is achieved. The connecting end 22 has protrusions on both sides, and a groove is provided horizontally at a corresponding position on the connecting member 12. The protrusions on the connecting end 22 are accommodated in the grooves. When the crank 2 rotates, the protrusions on the connecting end 22 move horizontally within the grooves, thereby driving the connecting member 12 to move vertically.

[0051] The drive end 23 is integrally formed with the rotating end 21 and the connecting end 22. The drive end 23 is used for the user to hold and apply force to drive the crank 2 to rotate.

[0052] The replacement brush head 3 is the component that directly performs pet grooming. The replacement part 31 is made of the same material as the housing 11 and must have a certain strength and toughness. The fit between the replacement part 31 and the receiving cavity 111 refers not only to the matching of shape and size, but also to the correspondence of the connection structure to achieve a stable connection.

[0053] The scraper 32 includes a base 321 and multiple blades 322. The multiple blades 322 are arranged in a matrix on the base 321. The blades 322 can be made of stainless steel wire, nylon wire or plastic. The blades 322 can be columnar structures with one end bent away from the base 321; the blades 322 can also be hook-shaped structures with the bent part on the end away from the base 321; one end of the multiple blades 322 can be connected to each other to form a comb-like structure.

[0054] The replacement part 31 has an opening, the base 321 of the scraper 32 is housed inside the replacement part 31, and the blade 322 protrudes from the opening of the replacement part 31 to the outside of the replacement part 31. The blade 322 may be made of stainless steel wire, nylon wire or plastic, and the connector 12 abuts against the base 321 of the scraper 32 to provide support for the scraper 32.

[0055] Specifically, when a replacement brush head 3 needs to be installed, simply place the replacement part 31 into the receiving cavity 111 of the housing 11. After the pet brush is used, operate the drive end 23 of the crank 2 to make the drive end 23 drive the connecting end 22 to rotate around the rotating end 21. The protrusion on the connecting end 22 moves in the groove on the connecting part 12, thereby causing the connecting part 12 to slide in the sliding cavity. At this time, the connecting part 12 is away from the scraper 32. Since the scraper 32 and the replacement part 31 are slidably connected, when the blade 322 on the scraper 32 is pressed, the blade 322 will retract into the replacement part 31. At this time, the pet hair on the blade 322 will fall off the blade 322 under the obstruction of the replacement part 31, so as to facilitate the cleaning of the brush head 1.

[0056] In some embodiments, the connector is provided with a slide rail, and the connecting end is slidably placed in the slide rail. When the crank rotates, the connecting end rotates about the rotating end, and the connecting end slides on the slide rail, thereby causing the connector to reciprocate up and down.

[0057] Compared with the prior art, in this embodiment, the replacement part 31 is detachably connected to the housing 11, which allows users to flexibly replace different replacement brush heads 3 according to the pet's hair type, care needs, etc., without having to prepare multiple pet brushes, reducing economic costs and making it convenient to carry and store; at the same time, the crank 2 and the connector 12 are provided to facilitate users to clean the pet hair on the replacement brush head 3.

[0058] Please see Figure 4 as well as Figures 9 to 12 In this embodiment, a groove 41 is provided on the side wall of the replacement part 31, and a slider 42 is provided at the corresponding position of the housing 11, the slider 42 being adapted to the groove 41.

[0059] By setting a groove 41 on the replacement part 31 and a slider 42 on the outer shell, the replacement brush head 3 is detachably connected to the housing 11, making the installation process of the replacement brush head 3 smoother and more convenient, and reducing the installation difficulty. At the same time, it effectively restricts the horizontal movement of the replacement part 31, preventing the replacement brush head 3 from shaking or shifting during use, and further ensuring the stability and reliability of the connection. The cooperation structure between the slider 42 and the groove 41 is simple, easy to process and manufacture, and effectively reduces production costs.

[0060] Please see Figures 3 to 4 In this embodiment, the replacement part 31 is strip-shaped, and the accommodating cavity 111 is a groove with openings at the ends and top; the sliding groove 41 is placed on both sides of the replacement part 31, and the slider 42 is placed on the opposite side walls of the accommodating cavity 111.

[0061] The groove 41 is an elongated groove formed by injection molding or machining on the opposite side walls of the replacement part 31. The cross-section of the groove can be semi-circular, rectangular or trapezoidal, and the length of the groove 41 is the same as the length of the replacement part 31.

[0062] The slider 42 is an outwardly protruding structure provided on the inner wall of the accommodating cavity 111 at a corresponding position. It can be integrally formed with the shell 11 or fixed to the shell 11 by welding, screwing or other means. The material of the slider 42 is the same as that of the shell 11.

[0063] The shape of the slider 42 is adapted to the cross-section of the groove 41.

[0064] Specifically, when installing the replacement brush head 3, since the end of the receiving cavity 111 has an opening, the strip-shaped replacement part 31 can be inserted from the end opening. Simultaneously, the sliding grooves 41 on both sides of the replacement part 31 are aligned with the sliders 42 on the opposite side walls of the receiving cavity 111. Then, the replacement part 31 is pushed, causing the sliders 42 to slide along the sliding grooves 41 until the replacement part 31 is fully inserted into the receiving cavity 111. The sliders 42 and 41 are compatible; during sliding, the sliding grooves 41 guide the sliders 42, ensuring that the replacement part 31 can accurately and smoothly enter the receiving cavity 111. After installation, the sliders 42 and 41 engage, restricting the movement of the replacement part 31 in the direction perpendicular to the length of the sliding grooves 41. Since the pet brush moves in the same direction as the length of the sliding grooves 41 during use, the engagement of the sliders 42 and 41 prevents the replacement brush head 3 from falling off during pet brush use.

[0065] The strip-shaped replacement part 31 is adapted to the groove-shaped receiving cavity 111. The sliding grooves 41 on both sides of the replacement part 31 and the slider 42 on the inner wall of the receiving cavity 111 cooperate with each other, making the installation and removal of the replacement brush head 3 simpler and more efficient, and significantly shortening the replacement time.

[0066] Please see Figures 9 to 12 In some embodiments, the replacement part 31 is a cylinder, and the accommodating cavity 111 is a blind hole with an opening at the top; the slide 41 is L-shaped, and one end of the slide 41 has an opening facing downwards.

[0067] The diameter of the accommodating cavity 111 is adapted to the diameter of the replacement part 31, and the top opening is chamfered to facilitate the insertion and removal of the replacement part 31.

[0068] Optionally, there are multiple grooves 41, which are evenly arranged on the side wall of the replacement part 31.

[0069] Slider 42 is provided at corresponding positions on the inner wall of the accommodating cavity 111. The number of sliders 42 is the same as the number of grooves 41, and the sliders 42 are evenly distributed on the inner wall of the accommodating cavity 111.

[0070] Specifically, when installing the replacement brush head 3, the replacement part 31 is inserted into the receiving cavity 111 through the top opening. Simultaneously, the slider 42 on the inner wall of the receiving cavity 111 is aligned with the downward opening of the L-shaped groove 41 on the replacement part 31. The slider 42 is then slid upwards along the longitudinal portion of the groove 41. When the slider 42 reaches the end of the longitudinal portion, the replacement part 31 is rotated, causing the slider 42 to enter the transverse portion of the groove 41. At this point, the slider 42 is confined within the transverse portion of the L-shaped groove 41 and can no longer move longitudinally, thus fixing the replacement part 31 in the receiving cavity 111. For disassembly, the replacement part 31 is rotated in the opposite direction, causing the slider 42 to return from the transverse portion to the longitudinal portion. Then, the replacement part 31 is lifted upwards, and the slider 42 disengages from the opening of the groove 41, allowing the replacement part 31 to be removed.

[0071] The L-shaped groove 41 and the slider 42 work together to achieve rotational fixation, which is simple and quick to operate. Simply insert and rotate to fix it. To disassemble, simply rotate in the opposite direction. This makes it convenient for users to install and remove the brush head 3. After the slider 42 enters the horizontal part of the L-shaped groove 41, it can effectively prevent the replacement part 31 from falling upward during use, ensuring the safety and stability of the use process.

[0072] Please see Figures 1 to 2 In some embodiments, a first magnetic suction member 51 is provided at the bottom of the accommodating cavity 111, and a second magnetic suction member 52 is provided on the bottom surface of the replacement member 31; wherein, when the replacement brush head 3 is placed in the accommodating cavity 111, the first magnetic suction member 51 and the second magnetic suction member 52 are magnetically attracted.

[0073] The first magnetic component 51 is a permanent magnet, such as a neodymium iron boron magnet. Its shape can be designed as round, square, etc., according to the shape of the bottom of the accommodating cavity 111. It is fixed to the bottom of the accommodating cavity 111 by means of adhesive or inlay. One side of the magnet is flush with the bottom of the accommodating cavity 111 to avoid affecting the placement of the replacement component 31.

[0074] The second magnetic chuck 52 is a permanent magnet with the opposite magnetic properties to the first magnetic chuck 51, or it can be a metal block made of ferromagnetic materials such as iron, cobalt, or nickel. If the second magnetic chuck 52 is a permanent magnet, the installation method is similar to that of the first magnetic chuck 51, and it is fixed to the bottom surface of the replacement part 31; if the second magnetic chuck 52 is a metal block, it is fixed to the bottom surface of the replacement part 31 by welding or threaded connection.

[0075] The size of the second magnetic attractor 52 matches that of the first magnetic attractor 51, ensuring that the first magnetic attractor 51 and the second magnetic attractor 52 can make full contact to generate sufficient magnetic attraction.

[0076] Specifically, when the replacement part 31 is placed into the accommodating cavity 111, the first magnetic attraction part 51 at the bottom of the accommodating cavity 111 and the second magnetic attraction part 52 on the bottom surface of the replacement part 31 approach each other. Due to the magnetic attraction between the two, a mutual attraction force is generated, which pulls the replacement part 31 towards the bottom of the accommodating cavity 111, so that the replacement part 31 fits more tightly in the accommodating cavity 111.

[0077] The first magnetic component 51 and the second magnetic component 52 are magnetically connected, which can play an auxiliary positioning role during the installation of the replacement component 31. The magnetic force will guide the replacement component 31 to automatically align and fit the bottom of the receiving cavity 111, making the installation more accurate and labor-saving. When it is necessary to remove the replacement brush head 3, only a certain force needs to be applied to overcome the magnetic force to remove the replacement component 31. The operation is convenient and reduces the difficulty of installing and removing the replacement brush head 3.

[0078] Please see Figures 7 to 8 In some embodiments, the pet brush further includes: a spring piece 61; a notch for accommodating the spring piece 61 is provided on the side wall of the replacement part 31, one side of the spring piece 61 is connected to the replacement part 31, and a locking block 62 is provided on the side of the spring piece 61 away from the replacement part 31; a slot 63 corresponding to the locking block 62 is provided at the corresponding position of the accommodating cavity 111.

[0079] The spring piece 61 can be made of spring steel or highly elastic plastic and is set on the opposite side walls of the replacement part 31. One side of the spring piece 61 is connected to the replacement part 31 by welding, riveting or integral molding, and the other side is a free end, which can bend and deform under force and quickly return to its original shape after the external force is removed.

[0080] Furthermore, there is a gap between the end of the spring piece away from the replacement piece and the replacement piece, thereby providing space for elastic deformation.

[0081] The locking block 62 is a protruding structure integrally formed or fixedly installed on the outside of the free end of the spring piece 61, and its shape can be hemispherical or triangular.

[0082] The slot 63 is a recess on the side wall of the receiving cavity 111 that matches the locking block 62. The width of the slot 63 is slightly larger than the width of the locking block 62, and the edge of the slot 63 is chamfered to facilitate the entry of the locking block 62. The position of the slot 63 corresponds to the position of the locking block 62 on the spring 61, ensuring that the locking block 62 can accurately enter the slot 63 when the replacement part 31 is installed in place.

[0083] Specifically, during the installation of the replacement brush head 3, as the replacement part 31 is placed into the receiving cavity 111, the inner wall of the receiving cavity 111 exerts a squeezing force on the locking block 62 on the spring piece 61, causing the spring piece 61 to deform. The locking block 62 then enters the receiving cavity 111, allowing the replacement part 31 to smoothly enter. Once the replacement part 31 is fully inside the receiving cavity 111, the locking block 62 reaches the position of the locking groove 63. At this point, the squeezing force on the spring piece 61 disappears, and the spring piece 61 returns to its original shape, causing the locking block 62 to pop out and enter the locking groove 63. The locking block 62 and the locking groove 63 engage, fixing the replacement part 31 in the receiving cavity 111. During disassembly, pressing the spring piece 61 causes it to deform, and the locking block 62 exits from the locking groove 63. The replacement part 31 can then be removed from the receiving cavity 111.

[0084] The engaging structure of the locking block 62 and the locking slot 63 can effectively restrict the movement of the replacement part 31 in the accommodating cavity 111. Even when subjected to a large external force, the replacement brush head 3 is not easy to fall off, ensuring the safety of use. When installing the replacement brush head 3, simply put the replacement part 31 into the accommodating cavity 111 to automatically complete the locking and fixing. When disassembling, simply press the spring piece 61, which facilitates the installation and disassembly of the replacement brush head 3.

[0085] Please see Figures 1 to 12 In this embodiment, the pet brush further includes a handle 7, which is connected to the brush head 1.

[0086] The handle 7 can be made of lightweight and non-slip materials, such as ABS plastic, rubber, or wood. The handle 7 can be cylindrical in shape, and its surface can be provided with non-slip textures, raised dots, or rubber sleeves to increase friction when gripping and prevent slipping during use.

[0087] The connection between the handle 7 and the brush head 1 can be a threaded connection, a snap-fit ​​connection, or a one-piece molding.

[0088] The handle 7 is designed to facilitate user operation and control. By holding the handle 7, users can more stably and accurately control the direction and force of the pet brush's movement, making the grooming action smoother and improving grooming efficiency.

[0089] Please see Figure 2 In this embodiment, the replacement brush head 3 further includes: a sliding post 33 and a sleeve 34; the sleeve 34 is slidably sleeved on the sliding post 33; the sliding post 33 is placed inside the replacement part 31 and is connected to the replacement part 31; the sleeve 34 is placed at both ends of the scraper 32.

[0090] The sliding column 33 is a columnar structure that can be made of metal or high-strength plastic. The sliding column 33 is fixed inside the replacement part 31 by welding, threaded connection or integral molding to ensure that the blade 322 on the scraper 32 will not shake or shift during the sliding process.

[0091] The sleeve 34 is a tubular structure that fits onto the sliding post 33. The material of the sleeve 34 is the same as that of the sliding post 33. The inner diameter of the sleeve 34 is slightly larger than the outer diameter of the sliding post 33 to ensure that the sleeve 34 can slide smoothly on the sliding post 33.

[0092] The sleeve 34 and the scraper 32 can be fixed by welding, bonding or snap-fitting, so that the scraper 32 can slide along the sliding post 33 together with the sleeve 34. The two sleeves 34 are respectively fitted on the two parallel sliding posts 33 to ensure that the scraper 32 remains horizontal during the sliding process and will not tilt.

[0093] The sleeve 34 can also be a cylindrical protrusion on the scraper 32, integrally formed with the scraper 32, and the protrusion is hollow inside.

[0094] Specifically, the sliding post 33 is fixed inside the replacement part 31, providing a fixed track for the sliding of the sleeve 34. Since the sleeve 34 is slidably fitted on the sliding post 33 and connected to both ends of the scraper 32, when the user needs to retract the scraper 32 back into the replacement part 31, he only needs to flip the pet brush and then turn the crank 2. The connecting part 12 moves away from the replacement part 31 under the drive of the crank 2. At this time, the scraper 32 loses the support of the connecting part 12 and can move along the length of the sliding post 33 under its own weight or external force, retracting into the replacement part 31, making it easier to clean the pet hair on the scraper 32.

[0095] The sliding column 33 guides the sleeve 34, ensuring that the sleeve 34 and the scraper 32 can only slide in a straight line and will not deviate laterally. The two parallel sliding columns 33 and the corresponding sleeve 34 structure ensure the stability and balance of the scraper 32 when sliding.

[0096] A spring can be installed on the sliding column 33, with one end of the spring fixed to the replacement part 31 and the other end connected to the scraper 32. Specifically, when the connecting part 12 abuts against the base 321 of the scraper 32, the spring is stretched and deformed; when the scraper 32 needs to retract into the replacement part 31, the connecting part 12 moves away from the scraper 32, and the scraper 32 quickly retracts into the replacement part 31 under the action of the spring.

[0097] Compared with the prior art, this utility model realizes the quick installation and removal of the replacement brush head 3 through the detachable connection structure between the replacement part 31 and the housing 11. Users can replace the brush head 1 in a short time without the need for tools, which greatly improves the convenience of use. By sliding the scraper 32 and the replacement part 31 together, and with the cooperation of the connector 12 and the crank 2, the scraper 32 can be retracted into the interior of the replacement part 31, which makes it easy for users to clean pet hair on the scraper 32.

[0098] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this utility model, this should not limit the scope of patent protection of this utility model. Any technical solutions resulting from equivalent structural or procedural substitutions or modifications made based on the essential concept of this utility model and utilizing the content described in the text and drawings of this utility model, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this utility model.
