[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a handheld cleaning brush that allows for convenient and quick replacement of cleaning cotton.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A handheld cleaning brush includes a cleaning brush body, a base plate connected to the lower side of the cleaning brush body, a sliding plate sleeved between the base plate and the cleaning brush body, an unlocking spring connected to one end of the sliding plate and the cleaning brush body, a handle on the cleaning brush body, a drive mechanism connected to the handle for driving the sliding plate to move, a hanging hole on the sliding plate, and a hanging piece on the side of the hanging hole near the unlocking spring; it also includes a cleaning cotton, a connecting plate connected to the cleaning cotton, a hook on the connecting plate, and the hook passing through the base plate and hanging on the hanging piece in the hanging hole.

[0008] When the drive mechanism of this invention moves the sliding plate, the plate moves in the direction of squeezing the unlocking spring. The hook on the connecting plate separates from the scraper in the hanging hole of the sliding plate, allowing the cleaning cotton to be quickly separated from the cleaning brush body. When installing the cleaning cotton, the unlocking spring pushes the hook on the connecting plate to engage with the scraper in the hanging hole, and the base plate limits the hook to prevent it from automatically unlocking. This invention enables quick replacement of the cleaning cotton and ensures reliable connection when the cleaning cotton is attached.

[0009] In a preferred embodiment of this invention, the slide plate is provided with a guide bevel, and a cavity is provided on the lower side of the guide bevel. A guide hole is provided on the handle. The driving mechanism includes a pressing block, the lower side of which has a wedge-shaped surface that mates with the guide bevel on the slide plate. A pressing rod is provided on the upper side of the pressing block, and a button is connected to the pressing rod, extending out of the cleaning brush body. When the button is pressed, the pressing rod and the pressing block move downwards, and the wedge-shaped surface of the pressing block pushes the guide bevel of the slide plate, causing the slide plate to move towards the unlocking spring, thus unlocking the hook and the hanging piece. After releasing the pressing rod, the unlocking spring pushes the slide plate back to its original position, and the hook and the hanging piece engage.

[0010] In a preferred embodiment of this invention, a limiting ring is fixed inside the guide hole, a pressing block is disposed below the pressing block, and a pressing rod passes through the limiting ring. A return spring is connected between the upper side of the limiting ring and the pressing rod. The limiting ring can block the pressing block and prevent it from coming off. When the button is released, the return spring drives the pressing rod to reset, and the wedge-shaped surface of the pressing block quickly separates from the guide bevel of the slide plate, improving the speed of slide plate reset.

[0011] In a preferred embodiment of this invention, the base plate has a through hole, through which the hook passes and is hung on a hanging piece within the hole. When the unlocking spring returns to its original position, the hanging hole and the through hole are misaligned, the hook engages with the hanging piece, and the through hole blocks the side of the hook away from the hanging piece. When the unlocking spring is compressed, the hanging hole and the through hole coincide, ensuring that the hook can disengage smoothly.

[0012] In a preferred embodiment of this invention, when the slide plate is not compressed, the side of the through hole away from the hanging piece contacts the back of the hook. When the hook engages with the hanging piece, the edge of the through hole can block the back of the hook, ensuring that the hook can reliably engage with the hanging piece and preventing the hook from automatically disengaging.

[0013] As a preferred embodiment of this utility model, the top of the hook is provided with an inclined surface, and the hanging piece is provided with a guide slope that cooperates with the inclined surface. When the hook and the hanging piece are pressed against each other, the inclined surface of the hook and the guide slope of the hanging piece slide relative to each other, ensuring that the hook can be smoothly engaged with the hanging piece.

[0014] In a preferred embodiment of this invention, a connecting post is provided at one end of the skateboard, and one end of the unlocking spring is sleeved on the unlocking spring. The connecting post can be reliably connected to the unlocking spring, ensuring that the unlocking spring can smoothly push the skateboard to move.

[0015] As a preferred embodiment of this utility model, a soft rubber frame is fitted around the edge of the cleaning brush body. The soft rubber frame protects the edge of the cleaning brush and reduces damage when the cleaning brush collides with other objects.

[0016] As a preferred embodiment of this utility model, a handle cover is fastened to the handle, and a hanging rope is connected to the end of the handle.

[0017] As a preferred embodiment of this utility model, the bottom of the base plate is provided with adhesive teeth for attaching cleaning tools. The adhesive teeth on the base plate allow for direct attachment of cleaning tools such as cloths.

[0018] The beneficial effects of this utility model are as follows:

[0019] When the drive mechanism of this invention moves the sliding plate, the plate moves in the direction of squeezing the unlocking spring. The hook on the connecting plate separates from the scraper in the hanging hole of the sliding plate, allowing the cleaning cotton to be quickly separated from the cleaning brush body. When installing the cleaning cotton, the unlocking spring pushes the hook on the connecting plate to engage with the scraper in the hanging hole, and the base plate limits the hook to prevent it from automatically unlocking. This invention enables quick replacement of the cleaning cotton and ensures reliable connection when the cleaning cotton is attached. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0033] like Figures 1-10 As shown, the handheld cleaning brush of this embodiment includes a cleaning brush body 1, a base plate 2 connected to the lower side of the cleaning brush body 1, a sliding plate 3 sleeved between the base plate 2 and the cleaning brush body 1, an unlocking spring 4 connected to one end of the sliding plate 3 and the cleaning brush body 1, a handle 5 provided on the cleaning brush body 1, a drive mechanism 6 for driving the sliding plate 3 to move connected to the handle 5, a hanging hole 31 provided on the sliding plate 3, and a hanging piece 32 provided on the side of the hanging hole 31 near the unlocking spring 4; it also includes a cleaning cotton 7, a connecting plate 8 connected to the cleaning cotton 7, a hook 81 provided on the connecting plate 8, and the hook 81 passes through the base plate 2 and hangs on the hanging piece 32 in the hanging hole 31.

[0034] When the drive mechanism 6 of this invention pushes the slide plate 3 to move, the slide plate 3 moves in the direction of squeezing the unlocking spring 4, and the hook 81 on the connecting plate 8 separates from the scraper in the hanging hole 31 of the slide plate 3, allowing the cleaning cotton 7 to be quickly separated from the cleaning brush body 1. When installing the cleaning cotton 7, under the push of the unlocking spring 4, the hook 81 on the connecting plate 8 engages with the scraper in the hanging hole 31, and the base plate 2 limits the hook 81 to prevent the hook 81 from automatically unlocking from the hanging piece 32. This invention enables quick replacement of the cleaning cotton 7 and ensures reliable connection when the cleaning cotton 7 is connected.

[0035] Specifically, the slide plate 3 is provided with a guide bevel 33, and a cavity 34 is provided on the lower side of the guide bevel 33. The handle 5 is provided with a guide hole 51. The drive mechanism 6 includes a pressing block 61, and a wedge-shaped surface 611 that mates with the guide bevel 33 on the slide plate 3 is provided on the lower side of the pressing block 61. A pressing rod 62 is provided on the upper side of the pressing block 61, and a button 63 is connected to the pressing rod 62. The button 63 extends out of the cleaning brush body 1. When the button 63 is pressed, the pressing rod 62 and the pressing block 61 move downward. The wedge-shaped surface 611 of the pressing block 61 pushes the guide bevel 33 of the slide plate 3, so that the slide plate 3 can move towards the unlocking spring 4, and the hook 81 unlocks the hanging piece 32. After the pressing rod 62 is released, the unlocking spring 4 pushes the slide plate 3 back to its original position, and the hook 81 engages with the hanging piece 32.

[0036] Furthermore, a limiting ring 52 is fixed inside the guide hole 51, and a pressing block 61 is disposed on the lower side of the pressing block 61. The pressing rod 62 passes through the limiting ring 52, and a return spring 64 is connected between the upper side of the limiting ring 52 and the pressing rod 62. The limiting ring 52 can block the pressing block 61 to prevent it from coming off. When the button 63 is released, the return spring 64 drives the pressing rod 62 to reset, and the wedge-shaped surface 611 of the pressing block 61 quickly separates from the guide inclined edge 33 of the slide plate 3, improving the reset speed of the slide plate 3.

[0037] Furthermore, the base plate 2 is provided with a through hole 21, through which the hook 81 passes and is hung on the hanging piece 32 inside the hanging hole 31. When the unlocking spring 4 returns to its original position, the hanging hole 31 and the through hole 21 are misaligned, and the hook 81 engages with the hanging piece 32. The through hole 21 blocks the side of the hook 81 away from the hanging piece 32. When the unlocking spring 4 is compressed, the hanging hole 31 and the through hole 21 coincide, ensuring that the hook 81 can be smoothly released.

[0038] When the slide plate 3 is not compressed, the side of the through hole 21 away from the hanging piece 32 contacts the back of the hook 81. When the hook 81 is engaged with the hanging piece 32, the edge of the through hole 21 can block the back of the hook 81, ensuring that the hook 81 can reliably engage with the hanging piece 32 and preventing the hook 81 from automatically disengaging.

[0039] The top of the hook 81 is provided with an inclined surface 811, and the hanging piece 32 is provided with a guide inclined surface 321 that cooperates with the inclined surface 811. When the hook 81 and the hanging piece 32 are pressed against each other, the inclined surface 811 of the hook 81 and the guide inclined surface 321 of the hanging piece 32 slide relative to each other, ensuring that the hook 81 can be smoothly engaged with the hanging piece 32.

[0040] A connecting post 35 is provided at one end of the sliding plate 3, and one end of the unlocking spring 4 is sleeved on the unlocking spring 4. The connecting post 35 can be reliably connected to the unlocking spring 4, ensuring that the unlocking spring 4 can smoothly push the sliding plate 3 to move.

[0041] The edge of the cleaning brush body 1 is fitted with a soft rubber frame 9. The soft rubber frame 9 can protect the edge of the cleaning brush and reduce damage when the cleaning brush collides with other objects.

[0042] A handle cover 53 is fastened to the handle 5, and a hanging rope 54 is connected to the end of the handle 5.

[0043] The bottom of the cleaning brush body 1 is provided with adhesive teeth 22 for attaching cleaning tools. The base plate 2 is provided with adhesive teeth 22, which can be used to directly attach cleaning tools such as rags.

[0044] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model.
