Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a toilet brush, a cleaning device, and a trash can. Background Technology

[0002] In daily life, cleaning the toilet is an essential part of maintaining home hygiene. However, stubborn dirt and limescale adhering to the inner wall of the toilet, especially in the drain and deep bends, are often difficult to remove completely, making cleaning tedious and inefficient. To address this problem, various brushes specifically designed for cleaning toilets have appeared on the market.

[0003] Currently, toilet cleaning brushes, based on the connection method between their brush head and handle, mainly fall into the following technical categories: The first type is the integrated, fixed structure. In this design, the brush head and handle are fixed together as an inseparable unit during manufacturing. The advantage of this approach is its robust structure, but the disadvantage is that when the bristles on the brush head wear down to the point where stains are difficult to remove, the user cannot replace the brush head separately and must discard the entire brush. This increases the user's long-term usage costs.

[0004] The second type uses a replaceable structure with a threaded connection. Users can remove and replace the brush head by rotating it. However, in actual toilet cleaning scenarios, the brush head will inevitably be covered in dirt after use. At this time, users need to manually rotate the brush head to remove it, which is not only unhygienic but also easily causes psychological discomfort to users.

[0005] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0006] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a toilet brush, a cleaning device, and a trash can, which can solve the problems of existing toilet brushes where the brush head and handle are a fixed one-piece structure, and the brush head cannot be replaced separately after wear, so the entire toilet brush must be discarded, increasing the long-term use cost; another type is a replaceable structure where the brush head and handle are threaded together, but after the brush head is contaminated with dirt, manually rotating and disassembling it is not only unhygienic, but also easily causes psychological discomfort to the user.

[0007] A toilet brush according to an embodiment of the present invention includes a brush head, a brush handle, a slide rod, a fixed shaft, a clamping block assembly, a first elastic element, and a driving element. The brush handle has a hollow structure and an opening at one end. The slide rod is disposed inside the brush handle, and a limiting groove and a clearance opening communicating with the limiting groove are provided at the end of the slide rod near the opening. The fixed shaft is disposed inside the brush handle, passing through the clearance opening and partially located within the limiting groove. The clamping block assembly includes a first clamping block and a second clamping block. The first ends of the first clamping block and the second clamping block are accommodated within the limiting groove, and the second ends of the first clamping block and the second clamping block pass through the opening and are exposed. The first clamping block and the second clamping block are respectively provided with a first through hole and a second through hole for the fixed shaft to pass through. The first clamping block and the second clamping block can rotate around the fixed shaft. The first elastic element is disposed between the first clamping block and the second clamping block and is used to provide elastic force for the first clamping block and the second clamping block to move away from each other. The driving member is connected to the slide rod and is used to drive the slide rod and the limiting groove thereon to move along the axial direction of the brush handle. The groove wall of the limiting groove is used to push against the first clamping block and the second clamping block when the slide rod moves toward the opening, so that the clamping ends overcome the elastic force of the first elastic element and move closer to each other.

[0008] A toilet brush according to an embodiment of this utility model has at least the following beneficial effects: When the brush head needs to be replaced due to wear, the driving component is operated to move the sliding rod away from the opening. At this time, the first elastic member disposed between the first clamping block and the second clamping block, by its own elastic restoring force, pushes the clamping ends of the first clamping block and the second clamping block to separate from each other, thereby releasing the clamping state of the brush head, and the user can remove the old brush head without any hindrance. Then, the driving component is operated again to move the sliding rod towards the opening. During the movement of the sliding rod, the wall of the limiting groove on it will contact the first clamping block and the second clamping block and generate a pushing force, forcing the first clamping block and the second clamping block to rotate around the fixed axis, so that their clamping ends come closer to each other, thereby tightly clamping the new brush head. From an effect perspective, this design effectively avoids the drawbacks of the traditional integrated fixed structure of brush head and brush handle, and avoids the increased cost caused by having to discard the entire brush due to brush head wear. At the same time, compared to the method of disassembling a toilet brush with a threaded connection that requires manually rotating the brush head to remove dirt, this toilet brush does not require such operation, which greatly improves the level of hygiene, avoids the psychological discomfort caused to users due to contact with dirt, and significantly enhances the convenience and comfort of use.

[0009] According to some embodiments of the present invention, the driving component includes a button, a through hole is provided on the side wall of the brush handle, the first end of the button is exposed through the through hole, the second end of the button extends into the brush handle and is provided with a first inclined surface, a second inclined surface is correspondingly provided on the slide rod, the first inclined surface and the second inclined surface abut against each other, and the button drives the slide rod and its limiting groove to move in a direction away from the opening through the cooperation of the first inclined surface and the second inclined surface.

[0010] According to some embodiments of the present invention, the driving component further includes a fixing block and a second elastic element. The fixing block is connected to the inner wall of the brush handle, and the two ends of the second elastic element are respectively connected to the fixing block and the slide rod. The second elastic element is used to provide the slide rod with an elastic force to move toward the opening to reset to the initial position.

[0026] Please refer to Figures 1-4According to an embodiment of the present invention, a toilet brush includes a brush head, a brush handle, a slide rod 20, a fixed shaft 23, a clamping block assembly, a first elastic member 32, and a driving member. The brush handle has a hollow structure and an opening at one end. The slide rod 20 is disposed inside the brush handle. The end of the slide rod 20 near the opening has a limiting groove 21 and a clearance opening 22 communicating with the limiting groove 21. The fixed shaft 23 is disposed inside the brush handle, passes through the clearance opening 22, and is partially located within the limiting groove 21. The clamping block assembly includes a first clamping block 30 and a second clamping block 31. The first ends of the first clamping block 30 and the second clamping block 31 are accommodated within the limiting groove 21, and the second ends of the first clamping block 30 and the second clamping block 31 pass through the opening and are externally... The first clamping block 30 and the second clamping block 31 are respectively provided with a first through hole and a second through hole for the fixed shaft 23 to pass through. The first clamping block 30 and the second clamping block 31 can rotate around the fixed shaft 23. The first elastic element 32 is disposed between the first clamping block 30 and the second clamping block 31 to provide elastic force for the first clamping block 30 and the second clamping block 31 to move away from each other. The driving element is connected to the slide rod 20 to drive the slide rod 20 and the limiting groove 21 on it to move along the axial direction of the brush handle. When the slide rod 20 moves toward the opening, the groove wall of the limiting groove 21 is used to push against the first clamping block 30 and the second clamping block 31, so that their clamping ends overcome the elastic force of the first elastic element 32 and move closer to each other.

[0027] When the brush head needs replacement due to wear, operate the drive mechanism to move the slide bar 20 away from the opening. At this time, the first elastic element 32, located between the first clamping block 30 and the second clamping block 31, uses its own elastic restoring force to push the clamping ends of the first clamping block 30 and the second clamping block 31 apart, thereby releasing the clamping state on the brush head. The user can easily remove the old brush head without any hindrance. Next, operate the drive mechanism again to move the slide bar 20 towards the opening. During the movement of the slide bar 20, the wall of its limiting groove 21 will contact the first clamping block 30 and the second clamping block 31 and generate a pushing force, forcing the first clamping block 30 and the second clamping block 31 to rotate around the fixed axis 23, bringing their clamping ends closer together and tightly clamping the new brush head. From an effectiveness perspective, this design effectively avoids the drawbacks of traditional integrated brush head and handle fixing structures, avoiding the increased cost caused by having to discard the entire brush due to brush head wear. At the same time, compared to the method of disassembling a toilet brush with a threaded connection that requires manually rotating the brush head to remove dirt, this toilet brush does not require such operation, which greatly improves the level of hygiene, avoids the psychological discomfort caused to users due to contact with dirt, and significantly enhances the convenience and comfort of use.

[0028] According to some embodiments of this utility model, the driving component includes a button 40, a through hole is provided on the side wall of the brush handle, the first end of the button 40 is exposed through the through hole, the second end of the button 40 extends into the brush handle and is provided with a first inclined surface 41, and a corresponding second inclined surface 42 is provided on the slide rod 20. The first inclined surface 41 and the second inclined surface 42 abut against each other. The button 40 drives the slide rod 20 and its limiting groove 21 to move in a direction away from the opening through the cooperation of the first inclined surface 41 and the second inclined surface 42.

[0029] When it is necessary to drive the slide bar 20 and its limiting groove 21 to move away from the opening, the user presses the first end of the button 40 exposed through the through hole. The first inclined surface 41 of the second end of the button 40 abuts against the second inclined surface 42 on the slide bar 20 and generates a force. With the cooperation of the inclined surfaces, the pressing force of the button 40 is converted into the moving force of the slide bar 20 away from the opening, causing the slide bar 20 to move. The movement of the slide bar 20 is achieved by simply pressing the button 40, which is convenient and quick to operate.

[0030] According to some embodiments of the present invention, the driving component further includes a fixing block 43 and a second elastic member 44. The fixing block 43 is connected to the inner wall of the brush handle, and the two ends of the second elastic member 44 are respectively connected to the fixing block 43 and the slide bar 20. The second elastic member 44 is used to provide the slide bar 20 with an elastic force to move toward the opening to reset to the initial position.

[0031] According to some embodiments of the present invention, a guide hole 24 extending along its axial direction is provided on the slide bar 20. The length of the guide hole 24 matches the length of the fixing block 43. The fixing block 43 passes through the guide hole 24. The button 40 is used to drive the limiting groove 21 and the slide bar 20 to move towards the fixing block 43 to compress the second elastic member 44.

[0032] When button 40 is pressed, slide bar 20 moves away from the opening, compressing the second elastic element 44. After the force of button 40 disappears, the second elastic element 44, relying on its own elastic restoring force, pulls slide bar 20 towards the opening until it returns to its initial position. The second elastic element 44 enables automatic reset of slide bar 20, eliminating the need for additional user intervention and simplifying the operation. The cooperation between guide hole 24 and fixing block 43 ensures the stability of slide bar 20's movement, preventing deviation during movement.

[0033] According to some embodiments of the present invention, the brush handle includes a fixing part 10 and an extension part 11. The fixing part 10 has an opening and an opening at both ends, and one end of the extension part 11 extends into the fixing part 10 through the opening. The extension part 11 is detachably connected to the fixing part 10.

[0034] When the brush handle length needs to be adjusted, the user can connect the extension part 11 through the opening into the fixing part 10, or detach the extension part 11 from the fixing part 10 to change the brush handle length. The detachable design of the fixing part 10 and the extension part 11 allows for flexible adjustment of the brush handle length, meeting the needs of different usage scenarios.

[0035] According to some embodiments of the present invention, the extended part 11 and the fixed part 10 are connected by a snap-fit ​​or a threaded connection.

[0036] If a threaded connection is used, the extension part 11 is screwed into the fixing part 10 to achieve the connection; rotating it in the opposite direction allows for disassembly. If a snap-fit ​​connection is used, the locking block 12 of the extension part 11 is inserted into the locking groove of the fixing part 10 to achieve the connection; disassembly is achieved by releasing the locking block 12 from the locking groove. The snap-fit ​​connection is simple to operate and allows for quick connection and disassembly of the extension part 11 and the fixing part 10; the threaded connection provides a secure connection and is less prone to loosening. Both connection methods have their advantages and can be selected according to actual needs, providing a reliable connection guarantee for adjusting the brush handle length.

[0037] According to some embodiments of the present invention, the brush head includes a cleaning cotton 50 and a connector 51. The connector 51 is fixedly installed on the cleaning cotton 50, and the clamping end of the clamping block assembly is used to clamp the connector 51.

[0038] When installing the brush head, place the brush head connector 51 between the clamping ends of the clamping block assembly. The clamping block assembly clamps the connector 51 through the action of the second elastic member 44 and the limiting groove 21. When disassembling, push the slider 20 with the button to move it away from the opening, causing the clamping block assembly to release the connector 51, and then remove the brush head. This ensures that the cleaning cotton 50 can be easily replaced, maintaining a good cleaning effect.

[0039] According to some embodiments of the present invention, the outer wall of the connector 51, the clamping surface of the first clamping block 30 and / or the clamping surface of the second clamping block 31 are provided with anti-slip texture.

[0040] When the clamping block assembly holds the connector 51, the anti-slip texture increases the friction between the outer wall of the connector 51 and the clamping surface of the clamping block, making the clamping more secure. During the cleaning process, even with a large external force, the brush head is not easily detached from the clamping block assembly.

[0041] According to some embodiments of the present invention, the connector 51 is provided with a protrusion 52 on the side away from the cleaning cotton 50, and the length of the protrusion 52 is greater than the distance between the clamping surfaces of the first clamping block 30 and the second clamping block 31 in the clamping state.

[0042] The design that the length of the protrusion 52 is greater than the distance between the clamping surfaces of the first clamping block 30 and the second clamping block 31 greatly enhances the connection stability between the brush head and the brush handle. During the use of the toilet brush, the protrusion 52 effectively prevents the connector 51 from detaching from the clamping block assembly, avoiding accidental drop of the brush head during use and ensuring the continuity and stability of the cleaning work.

[0043] Please refer to Figures 5-6 According to an embodiment of the present invention, the cleaning device includes a storage box 60 and a toilet brush. The storage box 60 has a first cavity 61 and a second cavity 62. The first cavity 61 is used to store the brush head of the toilet brush, and the second cavity 62 is used to store the handle of the toilet brush. A cover 63 is rotatably connected to the opening of the first cavity 61 for opening or closing the first cavity 61.

[0044] Users can open the cover 63 of the first cavity 61 to take out the brush head and install it onto the brush handle taken out from the second cavity 62. After use, the brush handle with the removed and soiled brush head can be put back into the second cavity 62, and the replacement brush head can be stored in the first cavity 61 and sealed by the cover 63.

[0045] A trash can according to an embodiment of the present invention includes a can body and a toilet brush, the toilet brush being detachably mounted on the can body.

[0046] When you need to clean the trash can with a toilet brush, remove the detachable brush from the can body to perform the cleaning; after cleaning, reinstall the brush onto the can body. The detachable design of the toilet brush makes it convenient to store and access.

[0047] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
