[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] See Figures 1 to 5 , an embodiment of the present application discloses a cleaning brush, including a cleaning brush 1, a brush head 2 and a brush handle 3. The cleaning brush 1 is connected to the brush head 2, the brush head 2 is connected to the front end of the brush handle 3, and an angle adjustment mechanism 4 is provided between the brush head 2 and the brush handle 3. The angle adjustment mechanism 4 includes a hinge shaft 41, an insert 42 and an insert driving part 43. The hinge shaft 41 is fixedly connected to the brush head 2, a hinge hole 31 is provided on the brush handle 3, and the hinge shaft 41 is inserted into the hinge hole 31 for the brush head 2 to rotate around the hinge shaft 41. The insert 42 is movably connected to the brush handle 3 and is arranged to approach or move away from the brush head 2. Two slots 21 for the front end of the insert 42 to be placed are provided on the brush head 2, and the insert driving part 43 is installed on the brush handle 3 and is used to drive the movement of the insert 42.
[0032] Specifically, in order to ensure the overall stability of the cleaning brush, the brush handle 3 includes a rod body 32 and a hinge part 33. The hinge part 33 is fixed to the front end of the rod body 32. The hinge part 33 includes two spliced connecting parts 331. The two connecting parts 331 are located at both ends of the hinge shaft 41, and the hinge holes 31 are provided at the ends of the two connecting parts 331 far from the rod body 32.
[0033] In order to avoid the movement of the insert 42 getting stuck, a chute 332 with an opening facing the slot 21 is provided on the hinge part 33. The extending direction of the chute 332 is perpendicular to the axial direction of the hinge shaft 41, and the insert 42 is slidably arranged in the chute 332.
[0034] In order to ensure that the insert 42 is stably placed in the slot 21, the plug-in drive part 43 includes a spring 431, which is arranged in the slide groove 332, one end of the spring 431 is against the groove bottom 3321 of the slide groove 332, and the other end of the spring 431 is against the rear end of the insert 42.
[0035] For ease of operation, the plug-in drive portion 43 also includes a button 432, which is movably connected to the hinge portion 33. The insert 42 is provided with a wedge block 422 that gradually increases from front to back, and the button 432 is pressed against the inclined surface 4221 of the wedge block 422, that is, the insert 42 can be withdrawn from the slot 21 by pressing the button 432.
[0036] As can be known from the above, when operating the cleaning brush angle adjustment, it is necessary to press the button 432 in the driving unit. The button 432 pushes the wedge block 422 to move from front to back in the slide groove 332, compressing the spring 431, so that the spring 431 contracts and contacts the bottom 3321 of the slide groove 332. At this time, the insert 42 is also separated from the slot 21. After separation, the operator can adjust the angle of the brush head 2 as needed. After the angle changes, the operator releases the button 432, and the insert 42 fits into the slot 21 at different positions under the rebound force of the spring 431 to achieve the change of the angle. The operation is convenient, and the angle is firmly fixed after adjustment and is not easily displaced.
[0037] Continue to see Figures 1 to 5 In this embodiment, an anti-drop plate 3322 is provided at the opening of the slide groove 332, and a step 421 for abutting against the anti-drop plate 3322 is provided on the insert 42. The insert 42 is driven by the plug-in driving part 43 to move in the slide groove 332, thereby pushing the insert 42 to be placed in the slot 21. If there is no anti-drop plate 3322, the insert 42 is easy to fall out from the opening of the slide groove 332, so that the fit between the insert 42 and the slot 21 cannot be guaranteed. Therefore, under the action of the anti-drop plate 3322, the moving range of the insert 42 is limited, thereby improving stability. The step 421 for abutting against the anti-drop plate 3322 provided on the insert 42 facilitates the insertion of the insert 42 from the opening of the slide groove 332, thereby improving the smoothness of the insertion of the insert 42 into the slot 21.
[0038] See also Figure 1 In this embodiment, the rod body 32 is a telescopic rod structure, thereby adjusting the length of the cleaning brush to adapt to different occasions.
[0039] See also Figure 1 , Figure 4, in this embodiment, the two connecting members 331 are locked and spliced by bolts. In this way, the locking between the connecting members 331 is realized, which is reliable and convenient to disassemble. It not only improves the overall strength but also facilitates future maintenance.
