Description

Technical Field

[0001] This utility model relates to the field of cleaning brush technology, and in particular to a multi-angle adjustable cleaning brush structure. Background Technology

[0002] A cleaning brush is a common cleaning tool, usually consisting of bristles and a handle. The bristles are responsible for contacting the surface to be cleaned and directly working on the dirt; the handle provides convenience for holding and operating, allowing the user to better control the brush for cleaning.

[0003] Most existing cleaning brushes are one-piece designs, and the angle between the brush head and the handle cannot be adjusted. This makes it difficult to conform to the cleaning surface of different objects during the cleaning process. Users need to adjust their arm posture or grip to adapt to different objects, which can easily cause fatigue and reduce cleaning efficiency. Utility Model Content

[0004] To facilitate the adjustment of the cleaning brush angle during use, this application provides a multi-angle adjustable cleaning brush structure.

[0005] The multi-angle adjustable cleaning brush structure provided in this application adopts the following technical solution:

[0006] A multi-angle adjustable cleaning brush structure includes a brush handle and a brush head with bristles, and also includes an angle adjustment mechanism for adjusting the angle between the brush handle and the bristles. The angle adjustment mechanism includes a connecting frame, a sliding block, and an adjustment component. The connecting frame includes a clamping part and a rotating part. The brush head is detachably connected to the clamping part, and the clamping part is fixedly connected to the rotating part. The rotating part is rotatably connected to the brush handle, and the sliding block is slidably connected to the brush handle. The adjustment component is used to connect the sliding block and the rotating part. When the sliding block slides, the rotating part rotates.

[0007] By adopting the above technical solution, the sliding block slides on the brush handle, and the rotating part is driven to rotate by the adjustment component, thereby changing the angle of the brush head; the angle between the brush handle and the bristles is adjustable, which makes it easy to adjust the angle of the cleaning brush during use, and is suitable for a variety of cleaning scenarios, improving cleaning efficiency and versatility.

[0008] Preferably, the brush head has a snap-fit ​​groove that can engage with the clamp part. When the brush head is installed on the snap-fit ​​part, the clamp part and the snap-fit ​​groove engage with each other.

[0009] By adopting the above technical solution, the brush head slot and the clamp part are engaged by a snap-fit, and the fixation is achieved by the interlocking of the slot and the protrusion; the brush head is detachable, which makes it easy to replace worn bristles, reduces the cost of use, and makes installation and disassembly simple and the connection stable.

[0010] Preferably, the snap-fit ​​part and the rotating part are set at an angle, and after the brush head rotates 180° radially, the snap-fit ​​groove and the clamp part can still snap-fit ​​together.

[0011] By adopting the above technical solution, the flexibility of brush head use is increased. Users can rotate the brush head 180° as needed to change the direction and angle of the bristles to better fit cleaning surfaces of different shapes and angles.

[0012] Preferably, the adjusting assembly includes a gear, a rack, and a locking element. The gear is fixedly connected to the rotating part, the rack is fixedly connected to the sliding block, and the rack and gear are meshed together. The locking element is used to limit the sliding of the sliding block.

[0013] By employing the above technical solution, the meshing connection of gears and racks allows the sliding of the sliding block to be converted into the rotation of the rotating part, thereby achieving precise adjustment of the angle between the brush handle and the bristles. A locking element restricts the sliding of the sliding block to a fixed angle; this ensures precise adjustment of the brush head angle, guarantees angle stability after adjustment, and meets different cleaning strength and precision requirements.

[0014] Preferably, the locking element includes a spring and a button. The brush handle has a sliding groove, and the side wall of the sliding groove has multiple limiting grooves. The button is slidably connected to the sliding block along the axis of the gear. One end of the button passes through the sliding groove to the outside. The button has several limiting blocks that can cooperate with the limiting grooves. The spring is located on the sliding block. The spring always drives the button to move away from the sliding block. When the button slides away from the sliding block to its limit position, the limiting blocks cooperate with the limiting blocks respectively.

[0015] By adopting the above technical solution, the limiting block on the spring-driven button cooperates with the limiting groove on the side wall of the brush handle slide to lock the angle. Pressing the button overcomes the spring force and releases the limiting of the sliding block, ensuring the stability of the angle during use and reducing the possibility of the sliding block accidentally sliding and causing the angle to change.

[0016] Preferably, one end of the brush handle is provided with an opening groove, and the rotating part is rotatably connected in the opening groove. The opening groove is gradually widened from the side away from the clamping part to the side close to the clamping part.

[0017] By adopting the above technical solution, the gradually expanding opening groove is conducive to the rotation of the rotating part, making the rotating part rotate more smoothly, reducing friction and interference with the brush handle, and at the same time limiting the rotation of the active part of the rotating part.

[0018] The main technical effects of this utility model are reflected in the following aspects:

[0019] 1. This utility model, by setting an angle adjustment mechanism, allows the sliding block to slide on the brush handle, and drives the rotating part to rotate through the adjustment component, thereby changing the angle of the brush head; thus realizing the adjustable angle between the brush handle and the bristles, making it convenient to adjust the angle of the cleaning brush during use, applicable to various cleaning scenarios, and improving cleaning efficiency and versatility.

[0020] 2. This utility model increases the flexibility of brush head use by having the brush head snapped onto the clamp. Users can rotate the brush head 180° as needed to change the orientation and angle of the bristles, so as to better fit cleaning surfaces of different shapes and angles.

[0021] 3. This utility model uses a spring and a button. The spring drives the limiting block on the button to cooperate with the limiting groove on the side wall of the brush handle slide to lock the angle. Pressing the button overcomes the spring force and releases the limiting of the sliding block, ensuring the stability of the angle during use and reducing the possibility of the angle changing due to accidental sliding of the sliding block.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0030] This application discloses a multi-angle adjustable cleaning brush structure.

[0031] Reference Figure 1 and Figure 5 This embodiment of a multi-angle adjustable cleaning brush structure includes a brush handle 1 and a brush head 2 with bristles 3, and also includes an angle adjustment mechanism 4. The adjustment mechanism is used to adjust the angle between the brush handle 1 and the bristles 3. The angle adjustment mechanism 4 includes a connecting frame 5, a sliding block 6 and an adjustment component 7. The connecting frame 5 includes a clamping part 8 and a rotating part 9. The brush head 2 is detachably connected to the clamping part, and the clamping part 8 is fixedly connected to the rotating part 9. The rotating part 9 is rotatably connected to the brush handle 1. The sliding block 6 is slidably connected to the brush handle 1. The adjustment component 7 is used to connect the sliding block 6 and the rotating part 9. When the sliding block 6 slides, the rotating part 9 rotates.

[0032] Reference Figure 1 and Figure 5 The sliding block 6 slides on the brush handle 1, and the rotating part 9 is driven to rotate by the adjusting component 7, thereby changing the angle of the brush head 2; the angle between the brush handle 1 and the bristles 3 is adjustable, which makes it easy to adjust the angle of the cleaning brush during use, and is suitable for a variety of cleaning scenarios, improving cleaning efficiency and versatility.

[0033] Reference Figure 1 and Figure 6 The brush head 2 has a snap-fit ​​groove 10 that engages with the clamp part 8. When the brush head 2 is installed on the snap-fit ​​part, the clamp part 8 and the snap-fit ​​groove 10 engage. The snap-fit ​​groove 10 of the brush head 2 and the clamp part 8 engage with each other, and the groove and protrusion are interlocked to achieve fixation. This makes the brush head 2 detachable, facilitating the replacement of worn bristles 3, reducing usage costs, and providing simple installation and disassembly with a stable connection. The snap-fit ​​part and the rotating part 9 are set at an angle, and even after the brush head 2 is rotated 180° radially, the snap-fit ​​groove 10 and the clamp part 8 can still engage. This increases the flexibility of the brush head 2, allowing users to rotate the brush head 2 180° as needed to change the orientation and angle of the bristles 3 for better fit to cleaning surfaces of different shapes and angles.

[0034] Reference Figure 2 and Figure 3 The adjusting assembly 7 includes a gear 11, a rack 12, and a locking element 13. The gear 11 is fixedly connected to the rotating part 9. A connecting rod 19 is slidably connected to the brush handle 1. The two ends of the connecting rod 19 are fixedly connected to the rack 12 and the sliding block 6, respectively, and the rack 12 and gear 11 are meshed together. The locking element 13 is used to limit the sliding of the sliding block 6. Through the meshing connection of the gear 11 and rack 12, the sliding of the sliding block 6 can be converted into the rotation of the rotating part 9, thereby achieving precise adjustment of the angle between the brush handle 1 and the bristles 3. The locking element 13 restricts the sliding of the sliding block 6 to a fixed angle; it enables precise adjustment of the brush head 2 angle, ensuring that the angle is stable after adjustment and meeting the needs of different cleaning strengths and fineness.

[0035] Reference Figure 2 and Figure 4 The locking component 13 includes a spring 14 and a button 15. A sliding groove 16 is provided on the brush handle 1, and multiple limiting grooves 17 are provided on the side wall of the sliding groove 16. The button 15 is slidably connected to the sliding block 6 along the axis of the gear 11. One end of the button 15 passes through the sliding groove 16 to the outside. The button 15 is provided with several limiting blocks 18 that can cooperate with the limiting grooves 17. The spring 14 is provided on the sliding block 6. The spring 14 always drives the button 15 to move away from the sliding block 6. When the button 15 slides to the limit position away from the sliding block 6, the several limiting blocks 18 cooperate with the limiting blocks 18 respectively.

[0036] Reference Figure 1 and Figure 4 The spring 14 drives the limit block 18 on the button 15 to cooperate with the limit groove 17 on the side wall of the slide groove 16 of the brush handle 1 to lock the angle. Pressing the button 15 can release the limit on the sliding block 6 by overcoming the force of the spring 14, ensuring the stability of the angle during use and reducing the possibility of the sliding block 6 accidentally sliding and causing the angle to change.

[0037] Reference Figure 1 and Figure 2 One end of the brush handle 1 has an opening groove 20, and the rotating part 9 is rotatably connected in the opening groove 20. The opening groove 20 is gradually widened from the side away from the clamping part 8 to the side closer to the clamping part 8. The gradually widening opening groove 20 facilitates the rotation of the rotating part 9, making the rotation of the rotating part 9 smoother during the rotation process, reducing friction and interference with the brush handle 1, and at the same time, it plays a limiting role in the rotation of the active part of the rotating part 9.

[0038] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
