Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, specifically to a cleaning brush. Background Technology

[0002] Toilet cleaning is an important household chore, and as people's quality of life continues to improve, their demands for the practicality and convenience of toilet cleaning tools are increasing.

[0003] In related technologies, a cleaning brush with a replaceable brush head has emerged. The front end of the movable rod of this cleaning brush is fixed with vertical insertion teeth. During use, by controlling the extension and retraction of the movable rod, the vertical insertion teeth are driven to vertically insert into the disposable brush head. However, the vertical insertion method makes the installation stability of the disposable brush head poor and it is easy to fall off. Utility Model Content

[0004] In view of this, the present invention provides a cleaning brush to solve the problem of poor installation stability and easy detachment of disposable brush heads in related technologies.

[0005] In a first aspect, this utility model provides a cleaning brush, characterized in that it comprises:

[0006] The brush head mounting base includes multiple needle-like structures for mounting brush heads.

[0007] A drive component that can be driven to move relative to the brush head mounting seat, and the drive component is connected to the needle-like structure through transmission; when the drive component is driven to move relative to the brush head mounting seat, it drives multiple needle-like structures to move, so that the ends of the multiple needle-like structures move closer or further apart, so as to pierce the brush head or clamp the brush head after piercing the brush head.

[0008] Beneficial effects: In this solution, by controlling the movement of the drive component relative to the brush head mounting seat, the ends of multiple needle-like structures in the brush head mounting seat can be controlled to move closer or further apart, thereby facilitating the insertion into the brush head or clamping the brush head after insertion, making the brush head less likely to fall off after installation and improving the stability of the brush head installation.

[0009] In one alternative embodiment, the brush head mounting base includes a rotating structure, on which needle-like structures are disposed; when the driving member is driven to move relative to the brush head mounting base, it drives the rotating structure to rotate, so that the ends of the multiple needle-like structures move closer or further apart from each other, so as to pierce the brush head or clamp the brush head after piercing the brush head.

[0010] In one optional embodiment, the rotating structure includes a rotating part and a rotating shaft. The rotating part includes a first rotating end and a second rotating end. The rotating shaft is disposed between the first rotating end and the second rotating end. The needle-like structure is disposed at the first rotating end. The second rotating end is connected to the driving member for transmission. When the driving member is driven to move relative to the brush head mounting seat, it drives the second rotating end to rotate around the rotating axis in a direction that approaches or moves away from the brush head, thereby causing the first rotating end to rotate in the same direction. This causes the ends of the needle-like structures to approach or move away from each other, so as to pierce the brush head or clamp the brush head after piercing the brush head.

[0011] In one optional embodiment, the rotating part is a plate-shaped member, the first rotating end and the second rotating end are the two ends of the plate-shaped member along the length direction, the rotating shaft is columnar, and the length direction of the plate-shaped member and the axial direction of the rotating shaft form a cross-shaped rotatable structure.

[0016] In one alternative embodiment, the limiting part is a groove-shaped structure, and the second rotating end is inserted into the groove-shaped structure when it is in the initial position.

[0017] In one alternative embodiment, the top cover assembly includes a snap-on cover and a housing, the housing being fixedly connected to the base plate, the snap-on cover being disposed between the housing and the base plate, and forming a axial groove with the base plate.

[0019] In one optional embodiment, the brush head mounting base further includes a transmission structure, which is connected to multiple rotating structures and to a driving member; when the driving member is driven to move relative to the brush head mounting base, it drives the transmission structure to move; the transmission structure drives multiple rotating structures to rotate simultaneously.

[0020] In one optional embodiment, the transmission structure includes a transmission part and a pushing part. The pushing part is a plate-shaped structure. One side of the pushing part abuts against multiple rotating structures, and the other side is provided with the transmission part. When the driving member is driven to move relative to the brush head mounting seat to abut against the end of the transmission part and push the transmission part to move, the transmission part drives the pushing part to push against multiple rotating structures at the same time, thereby driving multiple rotating structures to rotate at the same time.

[0021] In one alternative embodiment, the cleaning brush further includes a handle, with a brush head mounting seat at the end of the handle. A drive member is disposed on the handle, and the end of a transmission part extends out of the brush head mounting seat and into the handle.

When the driving member is driven to move relative to the brush head mounting base, it drives the second rotating end of the rotating structure to move, so that the second rotating end can move and drive the ends of the needle-like structures at the first rotating end to move closer or further apart. The first reset structure is used to reset the second rotating end after it is driven to move, thereby resetting the needle-like structure.

[0024] In one optional embodiment, the first reset structure is a first elastic reset part; when the second rotating end moves under the drive of the driving member, it causes the first elastic reset part to deform and store force; when the first elastic reset part recovers its deformation to release the force, it drives the second rotating end to reset.

One side of the reset drive plate abuts against one end of the first elastic member, and the other side of the reset drive plate abuts against the second rotating end. The other end of the first elastic member abuts against the brush head mounting seat. When the second rotating end moves under the drive of the drive member, it pushes the reset drive plate to move, and the reset drive plate squeezes the first elastic member, causing the first elastic member to deform and store force. When the first elastic member recovers its deformation to release the force, it pushes the reset drive plate to move in the opposite direction, thereby driving the second rotating end to reset.

[0037] In one optional embodiment, the driving component further includes a push button connected to the push rod. The brush handle is provided with a sliding groove, and the push button is slidably disposed in the sliding groove, with the end of the push button located outside the brush handle.

[0059] 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, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0060] In related technologies, a cleaning brush with a replaceable brush head has emerged. The front end of the movable rod of this cleaning brush is fixed with vertical insertion teeth. During use, by controlling the extension and retraction of the movable rod, the vertical insertion teeth are driven to vertically insert into the disposable brush head. However, the vertical insertion method makes the installation stability of the disposable brush head poor and it is easy to fall off.

[0061] To solve the above problems, the following will combine... Figures 1 to 10 The following describes embodiments of the present invention.

[0062] According to an embodiment of the present invention, in one aspect, a cleaning brush is provided, such as... Figures 1-3 As shown, the cleaning brush includes a brush head mounting base 1 and a drive member 2 that can be driven to move relative to the brush head mounting base 1. The brush head mounting base 1 includes multiple needle-like structures 11 for mounting the brush head. The drive member 2 is kinetically connected to the needle-like structures 11. When the drive member 2 moves relative to the brush head mounting base 1, it can drive the multiple needle-like structures 11 to move, causing the ends of the multiple needle-like structures 11 to move closer or further apart, so as to pierce the brush head or clamp the brush head after piercing it, thereby making it less likely for the brush head to fall off after installation and improving the stability of the brush head installation.

[0063] by Figure 3 For example, in its natural state, multiple needle-like structures 11 combine to form a closed "claw" shape. At this time, the opening angle of the needle-like structures 11 relative to the center of the brush head mounting base 1 is less than 90 degrees, that is, the needle-like structures 11 are inclined in the direction of approaching the center of the brush head mounting base 1. When the driving member 2 is driven to move closer to the brush head mounting base 1, it drives the multiple needle-like structures 11 to move, increasing the opening angle of the needle-like structures 11 relative to the center of the brush head mounting base 1 until they are in a vertical state relative to the brush head, that is, the "claw" opens to pierce the brush head. When the driving member 2 is driven to move away from the brush head mounting base 1, it drives the "claw" to close, that is, it drives the needle-like structures 11 to return to a position where the opening angle relative to the center of the brush head mounting base 1 is less than 90 degrees, thereby clamping the brush head. Alternatively, when the driving component 2 is driven away from the brush head mounting base 1, it drives multiple needle-like structures 11 to move, causing the "claws" to open so as to pierce the brush head. When the driving component 2 is driven closer to the brush head mounting base 1, it causes the "claws" to close, thereby clamping the brush head.

[0064] Furthermore, the portion of the needle-like structure 11 that pierces the brush head can also have a barb-like shape, thereby further enhancing the stability of the brush head installation and making it less likely to fall off after being pierced.

[0065] Understandably, multiple needle-like structures 11 can also combine to form an outwardly opening "flower" shape in their natural state. In this case, the opening angle of the needle-like structures 11 relative to the center of the brush head mounting base 1 exceeds 90 degrees, meaning the needle-like structures 11 are tilted away from the center of the brush head mounting base 1. When the driving member 2 is driven to move closer to the brush head mounting base 1, it drives the multiple needle-like structures 11 to move, reducing the opening angle of the needle-like structures 11 relative to the center of the brush head mounting base 1 until the brush head is in a vertical state, i.e., the "flower" closes to facilitate insertion into the brush head. When the driving member 2 is driven to move away from the brush head mounting base 1, it drives the "flower" to open, i.e., it drives the needle-like structures 11 to return to a position where the opening angle relative to the center of the brush head mounting base 1 exceeds 90 degrees, thereby clamping the brush head. Alternatively, when the driving component 2 is driven away from the brush head mounting base 1, it drives multiple needle-like structures 11 to move, causing the "flower" to close so as to pierce the brush head. When the driving component 2 is driven closer to the brush head mounting base 1, the "flower" opens outward again, thereby clamping the brush head.

[0066] Preferably, multiple needle-like structures 11 are evenly arranged along the bottom edge of the brush head mounting base 1. It is understood that the arrangement of the needle-like structures 11 is not limited and can be any other arrangement, as long as they can move closer or further apart to clamp the brush head when driven.

[0067] In one embodiment, such as Figure 4 , Figure 5As shown, the brush head mounting base 1 includes a rotating structure 12, on which needle-like structures 11 are disposed. When the driving member 2 is driven to move relative to the brush head mounting base 1, it can drive the rotating structure 12 to rotate, causing the ends of the multiple needle-like structures 11 to move closer or further apart, so as to pierce the brush head or clamp the brush head after piercing it. The movement of the needle-like structures 11 by the rotating structure 12 has the characteristics of simple structure, low cost and high reliability.

[0068] Optionally, the plurality of needle-like structures 11 can all be disposed on a single rotating structure 12. When the driving member 2 is driven to move relative to the brush head mounting base 1, it can drive the rotating structure 12 to rotate. The rotation of the rotating structure 12 can cause the ends of the plurality of needle-like structures 11 to move closer or further apart. Alternatively, one of the plurality of needle-like structures 11 can be disposed on the rotating structure 12, and the plurality of needle-like structures 11 can be linked together. When the driving member 2 is driven to move relative to the brush head mounting base 1, it can drive the rotating structure 12 to rotate. At this time, the rotating structure 12 drives the needle-like structures 11 disposed thereon to move. Under the linkage between the plurality of needle-like structures 11, the ends of the plurality of needle-like structures 11 can be driven closer or further apart. Alternatively, the plurality of needle-like structures 11 can be disposed on a plurality of rotating structures 12 respectively. When the driving member 2 is driven to move relative to the brush head mounting base 1, it can drive the plurality of rotating structures 12 to rotate simultaneously, so that the ends of the plurality of needle-like structures 11 move closer or further apart.

[0069] It is understood that the driving component 2 can also be movably connected to multiple needle-like structures 11 simultaneously. When the driving component 2 is driven to move relative to the brush head mounting base 1, it directly drives the multiple needle-like structures 11 to move, so that the ends of the multiple needle-like structures 11 move closer or further apart, so as to pierce the brush head or clamp the brush head after piercing the brush head. The specific way in which the driving component 2 drives the multiple needle-like structures 11 to move is not limited here.

[0070] In one embodiment, such as Figure 4 , Figure 5 As shown, the rotating structure 12 includes a rotating part 121 and a rotating shaft 122. The rotating part 121 includes a first rotating end 1211 and a second rotating end 1212. The rotating shaft 122 is disposed between the first rotating end 1211 and the second rotating end 1212. The needle-like structure 11 is disposed at the first rotating end 1211, and the second rotating end 1212 is connected to the driving member 2 for transmission. When the driving member 2 is driven to move relative to the brush head mounting seat 1, it drives the second rotating end 1212 to rotate around the rotating shaft 122 in a direction closer to or away from the brush head, thereby causing the first rotating end 1211 to rotate in the same direction, thereby causing the ends of the needle-like structures 11 to move closer to or further away from each other, so as to pierce the brush head or clamp the brush head after piercing the brush head.

[0071] Optionally, a plurality of rotating structures 12 may be provided on the brush head mounting base 1, and each rotating structure 12 may have at least one needle-like structure 11 on one rotating end 1211. When the driving member 2 is driven to move relative to the brush head mounting base 1, it drives the second rotating ends 1212 of the plurality of rotating structures 12 to rotate around their rotation axis 122 in a direction closer to or away from the brush head, so that the first rotating ends 1211 of the plurality of rotating structures 12 all rotate, thereby causing the ends of the plurality of needle-like structures 11 provided on the first rotating ends 1211 of the plurality of rotating structures 12 to move closer to or further away from each other.

[0072] Specifically, the rotating structure 12 can be an integrated design of the rotating part 121 and the rotating shaft 122, or it can be formed by fixing the two parts 121 and 122 together; this is not limited here. The specific shapes of the rotating part 121 and the rotating shaft 122 can be plate-shaped, shaft-shaped, or other irregular shapes; this is also not limited here. In this embodiment, the rotating structure 12 includes a rotating part 121 and a rotating shaft 122. The rotating part 121 includes a first rotating end 1211 and a second rotating end 1212. The rotating shaft 122 is disposed between the first rotating end 1211 and the second rotating end 1212. A needle-like structure 11 is disposed at the first rotating end 1211. The second rotating end 1212 is connected to the driving member 2 for transmission. This design features simple structure, low cost, and high reliability.

[0073] In one embodiment, such as Figure 4 , Figure 5 As shown, the rotating part 121 is a plate-shaped member, the first rotating end 1211 and the second rotating end 1212 are the two ends of the plate-shaped member along the length direction, the rotating shaft 122 is columnar, and the length direction of the plate-shaped member and the axial direction of the rotating shaft 122 form a cross-shaped rotatable structure 12.

[0074] It is understandable that the plate-shaped rotating part 121 and the columnar rotating shaft 122 form a seesaw-like structure. When the second rotating end 1212 rotates around the rotating shaft 122, it can drive the first rotating end 1211 to rotate in the same direction. The seesaw structure in this embodiment has the characteristics of simple structure, low cost and high reliability.

[0075] In one embodiment, such as Figure 4 , Figure 5 As shown, the first rotating end 1211 is connected to the needle-like structure 11 in an L-shape. The end of the needle-like structure 11 faces the brush head direction, and the extension direction of the needle-like structure 11, the length direction of the plate-like part, and the axial direction of the rotating shaft 122 are perpendicular to each other.

[0076] It is understandable that the first rotating end 1211 and the needle-like structure 11 do not have to be perpendicular. It is sufficient that the first rotating end 1211 and the needle-like structure 11 are connected at an angle to form a hook-like structure. Multiple hook-like structures form a "claw" shape, which is beneficial for fixing the brush head after it is inserted into the brush head.

[0077] In one embodiment, such as Figure 5 , Figure 6 As shown, the brush head mounting base 1 also includes a top cover assembly 13 and a base plate 14, with the top cover assembly 13 fixedly connected to the base plate 14. The top cover assembly 13 has a first groove 1311, and the inner side of the base plate 14 has a second groove 141. After the top cover assembly 13 and the base plate 14 are fixedly connected, the first groove 1311 and the second groove 141 engage to form a shaft groove, and the rotating shaft 122 is inserted into the shaft groove, thereby allowing the rotating shaft 122 to rotate freely within the shaft groove. The engagement of the first groove 1311 and the second groove 141 to form a shaft groove facilitates the installation and removal of the rotating shaft 122.

[0078] It is understandable that the shapes of the first groove 1311 and the second groove 141 are not limited here, as long as they can accommodate the rotating shaft 122 to rotate within them after being engaged.

[0079] In one embodiment, such as Figure 5 , Figure 6 As shown, both the first groove 1311 and the second groove 141 are arc-shaped, so that the rotating shaft 122 can rotate more smoothly within the groove.

[0080] In one embodiment, such as Figure 6 As shown, a limiting part 1312 is provided on the side of the top cover assembly 13 near the bottom plate 14. When the limiting part 1312 abuts against the second rotating end 1212, the second rotating end 1212 is in the initial position where it is not driven by the driving member 2.

[0081] The limiting part 1312 can be a groove-shaped structure or a limiting rod or other component that serves a limiting function; no limitation is made here. It is understood that if the position of the second rotating end 1212 is not restricted, it may, after being subjected to shaking or other disturbances, disengage from its initial position abutting against the driving member 2, thus becoming undriveable. By limiting the position of the second rotating end 1212 with the limiting part 1312, the accidental disengagement of the second rotating end 1212 from its initial position can be effectively prevented, thereby improving the stability of the product during use and optimizing the user experience.

[0082] In one embodiment, such as Figure 6As shown, the limiting part 1312 is a groove-shaped structure, and the second rotating end 1212 is inserted into the groove-shaped structure when it is in the initial position. It can be understood that the groove-shaped structure has sidewalls, which not only limits the rotation angle of the second rotating end 1212, but also prevents it from wobbling left and right along the axial direction, making it more stable when rotating.

[0083] In one embodiment, such as Figures 6-8 As shown, the top cover assembly 13 includes a cover 131 and a housing 132. The housing 132 is fixedly connected to the base plate 14. The cover 131 is disposed between the housing 132 and the base plate 14 and forms a shaft groove with the base plate 14.

[0084] Optionally, the top cover assembly 13 can also be integrally formed from the cover 131 and the outer shell 132. In this embodiment, the top cover assembly 13 is detachably connected by the cover 131 and the outer shell 132, which facilitates the installation and disassembly of the overall structure of the brush head mounting base 1. At the same time, compared with integral molding, the top cover assembly 13 is composed of two parts, the cover 131 and the outer shell 132, which makes the mold opening process easier.

[0085] In one embodiment, such as Figure 6 As shown, a limiting part 1312 for limiting the initial position of the second rotating end 1212 is provided on the side of the cover 131 near the base plate 14.

[0086] In one embodiment, such as Figures 6-8 As shown, the brush head mounting base 1 also includes a transmission structure 15, which is connected to multiple rotating structures 12 and to the driving member 2. When the driving member 2 is driven to move relative to the brush head mounting base 1, it drives the transmission structure 15 to move, and the transmission structure 15 drives the multiple rotating structures 12 to rotate simultaneously.

[0087] Optionally, the drive unit 2 can also directly abut against multiple rotating structures 12. When the drive unit 2 is driven to move relative to the brush head mounting base 1, it directly drives multiple rotating structures 12 to rotate simultaneously. It is understood that there are multiple rotating structures 12. In this embodiment, the drive unit 2 can drive multiple rotating structures 12 to rotate simultaneously through the transmission structure 15, thereby achieving centralized control of all needle-like structures 11 and facilitating brush head installation operations for the user.

[0088] In one embodiment, such as Figures 6-8 As shown, the transmission structure 15 includes a transmission part 151 and a pushing part 152. The pushing part 152 is a plate-shaped structure. One side of the pushing part 152 abuts against multiple rotating structures 12, and the other side is provided with the transmission part 151. When the driving member 2 is driven to move relative to the brush head mounting seat 1 to abut against the end of the transmission part 151 and push the transmission part 151, the transmission part 151 drives the pushing part 152 to push the multiple rotating structures 12 simultaneously, thereby driving the multiple rotating structures 12 to rotate simultaneously.

[0089] Optionally, the pushing part 152 has a pushing inclined surface 1521, which abuts against the second rotating end 1212. When the driving member 2 is driven to move relative to the brush head mounting seat 1 to abut against the end of the transmission part 151 and push the transmission part 151, the transmission part 151 drives the pushing inclined surface 1521 of the pushing part 152 to push against multiple second rotating ends 1212 at the same time, thereby driving multiple rotating structures 12 to rotate at the same time.

[0090] In this embodiment, the pushing part 152 is a plate-shaped structure. One side of the pushing part 152 abuts against multiple rotating structures 12. When driven, the pushing part 152 can push multiple rotating structures 12 at the same time, thereby driving multiple rotating structures 12 to rotate at the same time, realizing centralized control of all needle-shaped structures 11, and facilitating the user to perform brush head installation operations.

[0091] In one embodiment, such as Figure 7 , Figure 8 As shown, the cleaning brush also includes a handle 3, with a brush head mounting base 1 at the end of the handle 3. A drive member 2 is mounted on the handle 3, and the end of a transmission part 151 extends from the brush head mounting base 1 and into the handle 3. The drive member 2 is driven to move along the handle 3 towards the brush head mounting base 1 until it abuts against the end of the transmission part 151, and then pushes the transmission part 151 away from the handle 3 by continuing to move towards the brush head mounting base 1.

[0092] Optionally, the end of the transmission part 151 may also be located inside the brush head mounting base 1, and the end of the drive member 2 may extend into the brush head mounting base 1. Furthermore, the drive member 2 may be located inside the brush handle 3 or outside the brush handle 3.

[0093] In this embodiment, the user can hold the brush handle 3 to drive the drive component 2 to move relative to the brush handle 3, which is simple and convenient to operate.

[0094] In one embodiment, such as Figures 5-8 As shown, the brush head mounting base 1 includes a first reset structure 16, which is in transmission cooperation with the needle-like structure 11 and is used to drive the needle-like structure 11 to reset after being driven to move.

[0095] Optionally, the first reset structure 16 can be an elastic reset structure, such as a reset structure with elastic elements such as springs or torsion springs, or it can be a non-elastic reset structure, such as a magnetic reset structure. For example, a magnet can be provided on the needle structure 11. In the initial state, the magnet on the needle structure 11 is attracted to the metal part of the brush head mounting base 1. After the driving member 2 drives the needle structure 11 to move, the magnet is separated from the metal part, but the magnetic force between them is still there. When the driving member 2 is no longer acting on the needle structure 11, the needle structure 11 is attracted back to its original position under the action of the magnetic force.

[0096] In this embodiment, the first reset structure 16 can drive the needle-like structure 11 to reset after being driven to move, so that the needle-like structure 11 can automatically clamp the brush head after inserting into the brush head, without the need for manual operation, which is convenient for users.

[0097] In one embodiment, such as Figures 5-8 As shown, the needle-like structure 11 is disposed at the first rotating end 1211 of the rotating structure 12. One side of the second rotating end 1212 of the rotating structure 12 is connected to the driving member 2, and the other side of the second rotating end 1212 is connected to the first reset structure 16. When the driving member 2 is driven to move relative to the brush head mounting base 1, it drives the second rotating end 1212 of the rotating structure 12 to move, so that the second rotating end 1212 can move and drive the ends of the needle-like structure 11 of the first rotating end 1211 to move closer or further apart. The first reset structure 16 is used to reset the second rotating end 1212 after it is driven to move, thereby resetting the needle-like structure 11.

[0098] In this embodiment, the second rotating end 1212 is moved and reset by the first elastic reset part, thereby driving the needle structure 11 to reset. It has the characteristics of simple structure, low cost and high reliability.

[0099] In one embodiment, such as Figures 5-8 As shown, the first reset structure 16 is a first elastic reset part. When the second rotating end 1212 moves under the drive of the driving member 2, it causes the first elastic reset part to deform and store force. When the first elastic reset part recovers its deformation to release the force, it drives the second rotating end 1212 to reset.

[0100] Optionally, the first elastic reset part may include an elastic element such as a spring or torsion spring, or a special material with elastic deformation and shape memory capabilities, such as an elastic alloy or elastic fiber material.

[0101] In this embodiment, the second rotating end 1212 is reset after being driven to move by the first elastic reset part, which has the characteristics of simple structure, low cost, long life and high reliability.

[0102] In one embodiment, such as Figures 5-8As shown, the first elastic reset part includes a reset drive plate 161 and a first elastic member 162. One side of the reset drive plate 161 abuts against one end of the first elastic member 162, and the other side of the reset drive plate 161 abuts against the second rotating end 1212. The other end of the first elastic member 162 abuts against the brush head mounting base 1. When the second rotating end 1212 moves under the drive of the drive member 2, it pushes the reset drive plate 161 to move, and the reset drive plate 161 squeezes the first elastic member 162, causing the first elastic member 162 to deform and store force. When the first elastic member 162 recovers its deformation to release the force, it pushes the reset drive plate 161 to move in the opposite direction, thereby driving the second rotating end 1212 to reset.

[0103] Specifically, the first elastic element 162 can be a spring or torsion spring, or a special material with elastic deformation and shape memory capabilities, and is not limited here. For example, if the first elastic element 162 is a spring, when the second rotating end 1212 moves under the drive of the drive element 2, it can cause the spring to compress and store force. When the spring extends and releases force, it can drive the second rotating end 1212 to reset.

[0104] In this embodiment, the reset drive board 161 can simultaneously drive all the second rotating ends 1212 to reset during the reset activity, which has the characteristics of simple structure, low cost and high reliability.

[0105] In one embodiment, such as Figures 6-8 As shown, the brush head mounting base 1 also includes a top cover assembly 13 and a bottom plate 14. The top cover assembly 13 and the bottom plate 14 form a shaft groove for mounting the rotating shaft 122 of the rotating structure 12. The rotating structure 12 is disposed in the cavity formed by the top cover assembly 13 and the bottom plate 14. The other end of the first elastic member 162 abuts against the bottom plate 14.

[0106] In this embodiment, the top cover assembly 13 and the bottom plate 14 form a shaft groove for mounting the rotating shaft 122 of the rotating structure 12, and the rotating structure 12 is disposed in the cavity formed by the top cover assembly 13 and the bottom plate 14, which is beneficial for the disassembly or installation of the rotating structure 12.

[0107] In one embodiment, such as Figures 1-2 , Figures 7-9 As shown, the cleaning brush also includes a brush handle 3, the end of which is movably connected to the brush head mounting base 1. The movable connection can be made by means including but not limited to hinge, universal steering structure, or ball head structure 4, so that the brush head mounting base 1 can swing relative to the brush handle 3.

[0108] In this embodiment, the brush head mounting base 1 can swing relative to the brush handle 3, which can better adapt to various cleaning scenarios, such as making it easier to clean the toilet from multiple angles.

[0109] In one embodiment, such as Figures 7-9 As shown, the brush handle 3 and the brush head mounting base 1 are movably connected by a ball joint structure 4. In this way, the brush head mounting base 1 can swing more flexibly relative to the brush handle 3, improving the flexibility and applicability during cleaning.

[0110] In one embodiment, such as Figures 7-9 As shown, the ball head structure 4 includes a spherical inner cavity 41 provided at the end of the brush handle 3 and an end head 42 provided at the end of the brush head mounting seat 1. The end head 42 extends into the spherical inner cavity 41, and the outer wall of the end head 42 is clearance-fitted with the inner wall of the spherical inner cavity 41 so that when the brush head mounting seat 1 swings relative to the brush handle 3, the outer wall of the end head 42 slides relative to the inner wall of the spherical inner cavity 41.

[0111] It is understandable that the positions of the spherical inner cavity 41 and the end 42 can be interchanged, that is, the end of the brush handle 3 is provided with the end 42, and the end of the brush head mounting base 1 is provided with the spherical inner cavity 41, with the end 42 extending into the spherical inner cavity 41.

[0112] In this embodiment, the end 42 extends into the spherical inner cavity 41, and the outer wall of the end 42 is in clearance fit with the inner wall of the spherical inner cavity 41 so that when the brush head mounting seat 1 swings relative to the brush handle 3, the outer wall of the end 42 slides relative to the inner wall of the spherical inner cavity 41. It has the characteristics of simple structure, easy production and disassembly, low cost and high reliability.

[0113] Optionally, end 42 can be a spherical structure or a hemispherical structure. Preferably, end 42 is a hemispherical structure, which saves material costs without affecting functionality. In addition, the top surface of the hemispherical structure can be recessed to form a bowl-shaped groove, thereby further saving material costs.

[0114] In one embodiment, such as Figures 7-9 As shown, the brush handle 3 is composed of a first handle body 31 with a first arc-shaped port and a second handle body 32 with a second arc-shaped port, which are detachably connected. The first arc-shaped port and the second arc-shaped port are fastened together to form a spherical inner cavity 41. In this embodiment, the first handle body 31 and the second handle body 32 are detachably connected, which facilitates the assembly and disassembly of the ball head structure 4.

[0115] Optionally, the spherical inner cavity 41 can also be integrally formed inside the brush handle 3. Or, as... Figures 7-9 As shown, the brush handle 3 can also be composed of a first handle body 31 with a first arc-shaped port, a second handle body 32 with a second arc-shaped port, and a third handle body 33 with a sliding groove 34. The first handle body 31 and the second handle body 32 are detachably connected, and the first handle body 31 is also detachably connected to the third handle body 33. Dividing the brush handle 3 into multiple detachable sections facilitates the assembly and disassembly of the ball head structure and other components, and also makes it easier to store and transport the cleaning brush.

[0116] In one embodiment, such as Figures 7-9 As shown, the cleaning brush also includes a handle sleeve 5, which is fitted and fixed to the outer wall of the handle formed after the first handle body 31 and the second handle body 32 are connected, further strengthening the connection between the first handle body 31 and the second handle body 32. Optionally, the handle sleeve 5 is threaded to the outer wall of the handle or fixedly connected by a snap-fit ​​or other connecting component. The threaded connection between the handle sleeve 5 and the outer wall of the handle is simple, reliable, and durable.

[0117] In one embodiment, such as Figure 2 As shown, the cleaning brush also includes a brush handle 3, the end of which is connected to the brush head mounting base 1, and a drive unit 2 is disposed on the brush handle 3. When the drive unit 2 is driven to move along the brush handle 3, it drives multiple needle-like structures 11 to move.

[0118] Optionally, when the driving member 2 is driven to move axially along the brush handle 3, it drives multiple needle-like structures 11 to move. Alternatively, when the driving member 2 is driven to move radially or circumferentially along the brush handle 3, it drives multiple needle-like structures 11 to move. Here, the direction of movement of the driving member 2 is not limited.

[0119] In this embodiment, the drive unit 2 is disposed on the brush handle 3, which makes it easy for the user to hold and operate.

[0120] In one embodiment, such as Figures 7-9 As shown, the driving component 2 includes a push rod 21 disposed inside the brush handle 3, and the driving end 211 of the push rod 21 is connected to the needle-like structure 11. The push rod 21 is driven to move along the axial direction of the brush handle 3 until the driving end 211 extends out from the end of the brush handle 3 near the brush head mounting seat 1 and extends into the brush head mounting seat 1, thereby driving the needle-like structure 11 in the brush head mounting seat 1 to move.

[0121] Optionally, the drive end 211 can directly push the needle structure 11 to move, or the needle structure 11 can be abutted on the inclined surface, and the drive end 211 pushes the needle structure 11 to move along the inclined surface when driven.

[0122] In this embodiment, the push rod 21 located inside the brush handle 3 drives the needle-like structure 11 in the brush head mounting base 1 to move, without the need for other complex drive structures. It features simple structure, low cost and high reliability.

[0123] In one embodiment, such as Figures 1-2 , Figure 10 As shown, the driving component 2 also includes a push button 22 connected to the push rod 21. The brush handle 3 is provided with a sliding groove 34, and the push button is slidably disposed in the sliding groove 34, with the end of the push button located outside the brush handle 3. When the end of the push button is driven to slide along the sliding groove 34, the push button drives the push rod 21 to move axially along the brush handle 3.

[0124] Optionally, the push button 22 can also be rotatably connected to the brush handle 3, similar to a "trigger" structure. When the end of the push button 22 is driven to rotate, the push button 22 can drive the push rod 21 to move along the axial direction of the brush handle 3.

[0125] In this embodiment, the user only needs to use one hand to control the movement of the push rod 4 by pushing the button 22, which is convenient and quick to use.

[0126] In one embodiment, such as Figure 2 , Figure 9 As shown, the cleaning brush also includes a second reset structure. The second reset structure is connected to the drive component 2 and is used to reset the drive component 2 after it is driven to move along the brush handle 3. The second reset structure can be an elastic reset structure or a non-elastic reset structure, such as a magnetic structure.

[0127] In this embodiment, the second reset structure can drive the drive component 2 to move along the brush handle 3 and then reset, so that the user does not need to perform a reset operation, thus making it more convenient for the user.

[0128] In one embodiment, such as Figure 2 , Figure 9 As shown, the second reset structure includes a second elastic element 6, one end of which abuts against the brush handle 3, and the other end against the driving element 2. When the driving element 2 is driven to move axially along the brush handle 3, the second elastic element 6 deforms to store force. When the second elastic element 6 recovers its deformation to release the force, it drives the driving element 2 to reset. The second elastic element 6 can be an elastic element such as a spring or torsion spring, or it can be a special material with elastic deformation and shape memory capabilities, such as an elastic alloy or elastic fiber material. The second elastic element 6 provides the reset force through its own elasticity, and has the characteristics of simplicity, reliability, and long service life.

[0129] In one embodiment, such as Figures 1-2 , Figures 7-9 As shown, the brush handle 3 is movably connected to the brush head mounting base 1, and the brush head mounting base 1 can swing relative to the brush handle 3. When the driving component 2 is driven to move along the axial direction of the brush handle 3, it drives the brush head mounting base 1 to swing to a fixed position and lock it.

[0130] Optionally, the brush handle 3 and the brush head mounting base 1 can be hinged, or connected via a ball joint structure 4 as described in the above embodiment; this is not limited here. When the driving member 2 is driven to move axially along the brush handle 3, it causes the brush head mounting base 1 to swing to a fixed position and lock. Alternatively, when the driving member 2 is driven to move non-axially along the brush handle 3, it causes the brush head mounting base 1 to swing to a fixed position and lock, for example, radially or circumferentially.

[0131] In this embodiment, the brush head mounting base 1 can swing flexibly relative to the brush handle 3 in its natural state, and can also swing to a fixed position and lock under the drive of the drive component 2. This not only allows for flexible adaptation to cleaning in various scenarios and from various angles, but also enables better cleaning of stubborn stains when the brush head mounting base 1 is locked in the locked position. For example, when cleaning the inner surface of a toilet, since the inner surface of a toilet is mostly concave and curved, the user can more easily clean from various angles when the brush head mounting base 1 can swing flexibly relative to the brush handle 3. When it is necessary to clean stubborn stains on the toilet surface, the user can drive the drive component 2 to swing the brush head to a fixed position and lock it. This allows the user to apply more force and more easily increase the friction during cleaning, thereby better cleaning stubborn stains.

[0132] In one embodiment, such as Figures 7-8 As shown, the brush head mounting base 1 has a guide surface. When the driving member 2 is driven to move axially along the brush handle 3 until the driving end 211 abuts against the guide surface, and continues to move so that the driving end 211 slides along the guide surface, the brush head mounting base 1 swings relative to the brush handle 3 under the force exerted by the driving end 211 on the guide surface. When the driving end 211 slides along the guide surface to a reference position on the guide surface, the brush head mounting base 1 swings to a fixed position and locks.

[0133] Optionally, the brush head mounting base 1 has a guide structure, which can replace the function of a guide surface. The drive unit 2 is driven to move along the axial direction of the brush handle 3, which in turn drives the guide structure to move, thereby causing the brush head mounting base 1 to swing relative to the brush handle 3 until it reaches a fixed position and locks in place.

[0134] Compared to other complex guide structures, the guide surface in this embodiment has the characteristics of simple structure, low cost and high reliability.

[0135] In one embodiment, such as Figures 7-8 As shown, the guide surface is the bottom wall of the arc-shaped groove formed by the recess of the brush head mounting seat 1, and the reference position is the lowest point of the bottom wall.

[0136] Optionally, the guide surface can also be a concave shape such as a "U" or "V", as long as it can achieve the above-mentioned guiding function.

[0137] In this embodiment, after the drive end 211 abuts against the bottom wall of the arc-shaped groove, it slides more smoothly along the guide surface, which makes the user feel better during operation and improves the user experience.

[0138] In one embodiment, such as Figures 7-8As shown, the drive end 211 has an arc-shaped contact. When the arc-shaped contact abuts against the guide surface and slides along the guide surface, the brush head mounting base 1 swings relative to the brush handle 3. When the arc-shaped contact slides along the guide surface to the reference position of the guide surface, the brush head mounting base 1 swings to a fixed position and locks.

[0139] Optionally, the contact can also be in a non-curved shape, such as a cone. Curved contacts slide more smoothly along the guide surface, providing a better feel for the user and enhancing the user experience.

[0140] In one embodiment, such as Figures 7-8 As shown, at least a portion of the transmission structure 15 extends out of the brush head mounting base 1, and a guide surface is provided at the end of the extended portion of the transmission structure 15.

[0141] Optionally, the transmission part 151 of the transmission structure 15 can extend out of the brush head mounting base 1 or be disposed inside the brush head mounting base 1. The guide surface can be disposed at the end or side of the protruding part of the transmission structure 15. The driving member 2 can be driven to move relative to the brush head mounting base 1 until it abuts against the guide surface at the end of the transmission part 151 and pushes the transmission part 151 to move. The transmission part 151 drives the pushing part 152 to push multiple rotating structures 12 simultaneously, thereby driving multiple rotating structures 12 to rotate simultaneously.

[0142] In this embodiment, at least a portion of the transmission structure 15 extends out of the brush head mounting base 1, and a guide surface is provided at the end of the extended portion of the transmission structure 15, so that the drive member 2 can control the movement of the needle structure 11 while controlling the swing of the brush head. This cleverly integrates structures with different functions, which not only reduces the cost of the structure, but also simplifies the user's operation of the cleaning brush and greatly facilitates the user's use.

[0143] In one embodiment, such as Figures 7-8 As shown, the end 42 extends into the spherical inner cavity 41, and the end 42 has a bowl-shaped groove. The end 42 has a hollow cavity, through which the transmission structure 15 passes through the brush head mounting base 1, such that the part of the transmission structure 15 that passes through is located in the bowl-shaped groove. Specifically, the transmission part 151 of the transmission structure 15 passes through the hollow cavity from the brush head mounting base 1 and is located in the bowl-shaped groove.

[0144] Optionally, the transmission structure 15 can also be entirely located inside the brush head mounting base 1, with the driving component 2 extending from the hollow cavity into the brush head mounting base 1 and abutting against the transmission part 151.

[0145] In this embodiment, the end head 42 extends into the spherical inner cavity 41, and the end head 42 has a bowl-shaped groove. The end head 42 has a hollow cavity, and the transmission part 151 of the transmission structure 15 passes through the hollow cavity from the brush head mounting seat 1 and is located in the bowl-shaped groove. This allows the drive member 2 to control the movement of the needle-like structure 11 while controlling the swing of the brush head. This cleverly integrates structures with different functions, which not only reduces the structural cost but also simplifies the user's operation of the cleaning brush, greatly facilitating the user's use.

[0146] For ease of understanding, the following is combined with Figures 1-10 The operating principle of the embodiments of this application is explained in detail.

[0147] Specifically, the cleaning brush in this application includes a brush handle 3, a push button 22, a push rod 21, a second elastic element 6, and a brush head mounting base 1. The push button 22 is slidably connected to the surface of the brush handle 3 through a sliding groove 34 on the brush handle 3. The push rod 21 is located inside the brush handle 3 and abuts against the push button 22. The second elastic element 6 is in a transmission cooperation with the push rod 21. One end of the brush handle 3 is movably connected to the end of the brush head mounting base 1 through a ball head structure 4.

[0148] The brush head mounting base 1 includes a transmission structure 15, a rotating structure 12, a needle-like structure 11, and a first elastic element 162. The push rod 21 is connected to the rotating structure 12 via the transmission structure 15. The needle-like structure 11 is mounted on the rotating structure 12, and the first elastic element 162 is engaged with the transmission structure 15. The rotating structure 12 includes a rotating part 121 and a rotating shaft 122. The rotating part 121 includes a first rotating end 1211 and a second rotating end 1212. The rotating shaft 122 is located between the first and second rotating ends 1211. The needle-like structure 11 is located at the first rotating end 1211, and the second rotating end 1212 is connected to the push rod 21 via the transmission structure 15. In their natural state, the multiple needle-like structures 11 combine to form a closed "claw" shape. At this time, the opening angle of the needle-like structures 11 relative to the center of the brush head mounting base 1 is less than 90 degrees, meaning the needle-like structures 11 are inclined towards the center of the brush head mounting base 1.

[0149] When using the cleaning brush of this application, the user can push the push button 22 to move along the sliding groove 34 on the brush handle 3 toward the brush head mounting seat 1, causing the push rod 21 to move toward the brush head mounting seat 1, compressing and storing force in the second elastic element 6. At the same time, the arc-shaped contact of the push rod 21 abuts against the guide surface (the bottom wall surface of the arc-shaped groove at the end of the transmission part 151) and slides along the guide surface to the reference point. On the one hand, the brush head mounting seat 1 swings relative to the brush handle 3 under the drive of the force applied by the push rod 21 on the guide surface, and the drive end 211 slides along the guide surface to... When the guide surface is in its reference position, the brush head mounting base 1 swings to a fixed position and locks in place. On the other hand, the push rod 21 pushes the transmission part 151 to move towards the brush head, causing the push part 152 to simultaneously squeeze multiple second rotating ends 1212 to rotate (at the same time, the first elastic element 162 is compressed and stores force), so that multiple first rotating ends 1211 rotate in the same direction, causing the ends of the needle-like components to move away from each other, increasing the opening angle of the needle-like structure 11 relative to the center of the brush head mounting base 1 until it is in a vertical state relative to the brush head, that is, the "claws" open to easily insert into the brush head. After the user releases their hand, the first elastic element 162 and the second elastic element 6 extend to release the force, and the movable structures inside the cleaning brush are all reset by force, causing the "claws" to close, that is, causing the needle-like structure 11 to reset to a position where the opening angle relative to the center of the brush head mounting base 1 is less than 90 degrees, thereby clamping the brush head. This application solves the problem of poor installation stability and easy detachment of disposable brush heads in related technologies.
