Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-3In this embodiment of the present invention, a rotatable brush includes a handle 1, a rotating shaft 6 rotatably connected inside the handle 1, one end of the rotating shaft 6 passing through the handle 1 and fixedly connected to a rotating head 9, a brush head 10 fixedly connected to the rotating head 9, a mounting cylinder 2 fixedly connected to the side of the handle 1 away from the brush head 10, a rotating cylinder 3 disposed on the outer wall of the mounting cylinder 2, a bearing 4 connected between the rotating cylinder 3 and the mounting cylinder 2, a drive cylinder 5 fixedly connected to the rotating cylinder 3, one end of a spring 7 connected to the inner wall of the drive cylinder 5, the other end of the spring 7 fixedly connected to the rotating shaft 6 passing through the handle 1, a rotating handle 8 fixedly connected to the drive cylinder 5, a first ratchet assembly connected between the handle 1 and the drive cylinder 5, and a second ratchet assembly connected between the handle 1 and the rotating shaft 6. This invention uses a first ratchet assembly to unidirectionally limit the movement between the rotating shaft 6 and the drive cylinder 5, and a second ratchet assembly to unidirectionally limit the movement between the handle 1 and the rotating shaft 6. When using the device, the operator holds the handle 1 with one hand and the rotating handle 8 with the other, and then twists the rotating handle 8. At this time, the rotating shaft 6 cannot rotate due to the limitation imposed by the second ratchet assembly. The rotating handle 8 then drives the drive cylinder 5 to rotate, which in turn drives the spring 7 to rotate and store energy. After the energy storage is complete, the operator controls the second ratchet assembly to open, thereby removing the limitation imposed by the second ratchet assembly on the rotating shaft 6. Then, the spring 7 releases its energy, thereby driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the rotating head 9 and the brush head 10 to rotate, thus performing a rotating cleaning action.

[0018] In one instance of this embodiment, please refer to Figures 1-3 The first ratchet assembly includes a first ratchet 11 fixedly connected to the outer wall of the drive cylinder 5. A first mounting bracket 12 is fixedly connected to the grip 1. A first mounting shaft 13 is rotatably connected inside the first mounting bracket 12. A first pawl 14 is fixedly connected to one end of the first mounting shaft 13. The first pawl 14 cooperates with the first ratchet 11. A push block 15 is fixedly connected to the other end of the first mounting shaft 13. A spring 16 is connected between the push block 15 and the grip 1. The first ratchet assembly limits the first ratchet 11 in one direction through the cooperation of the first ratchet 11 and the first pawl 14, thereby achieving one-way fixation of the drive cylinder 5. At the same time, the spring 16 elastically pushes the push block 15. The push block 15 drives the first pawl 14 to elastically fit against the first ratchet 11 through the second mounting shaft 19.

[0019] In one instance of this embodiment, please refer to Figures 1-3The second ratchet assembly includes a second ratchet 17 fixedly connected to a rotating shaft 6. A second mounting bracket 18 is fixedly connected to the grip 1. A second mounting shaft 19 is rotatably connected within the second mounting bracket 18. A second pawl 20 is fixedly connected to one end of the second mounting shaft 19, and the second pawl 20 cooperates with the second ratchet 17. A drive arm 21 is fixedly connected to the other end of the second mounting shaft 19. A spring 23 connects the drive arm 21 to the grip 1. A pull handle 22 is fixedly connected to the drive arm 21. The second ratchet assembly is formed by the interaction between the second ratchet 17 and the second pawl 20. The second ratchet 17 is unidirectionally limited, thereby achieving unidirectional fixation of the rotating shaft 6. At the same time, the drive arm 21 is elastically pushed by the spring 23. The drive arm 21 drives the second pawl 20 to elastically attach to the second ratchet 17 via the second mounting shaft 19. When it is necessary to rotate the rotating shaft 6, the user can pull the handle 22. The handle 22 drives the drive arm 21 to rotate and compresses the spring 23. The drive arm 21 drives the second pawl 20 to rotate away from the second ratchet 17 via the second mounting shaft 19, thereby causing the second ratchet 17 to lose its limit.

[0020] The working principle of this utility model is as follows: The spring 16 elastically pushes the push block 15. The push block 15, through the second mounting shaft 19, drives the first pawl 14 to elastically engage with the first ratchet 11. Thus, the first ratchet 11 is unidirectionally limited by the cooperation of the first ratchet 11 and the first pawl 14. The first ratchet 11 unidirectionally limits the movement between the rotating shaft 6 and the drive cylinder 5. Simultaneously, the second ratchet assembly unidirectionally limits the movement between the handle 1 and the rotating shaft 6. When using the device, the operator holds the handle 1 with one hand and the rotating handle 8 with the other, and rotates the rotating handle 8. At this time, the spring 23 elastically pushes the drive arm 21. The drive arm 21, through the second mounting shaft 19, drives the second pawl 20 to elastically engage with the second ratchet 17. The second ratchet 17 is then unidirectionally limited by the cooperation of the second ratchet 17 and the second pawl 20, thereby unidirectionally fixing the rotating shaft 6. At this time, the rotating shaft 6 cannot rotate. The rotating handle 8 drives the drive cylinder 5 to rotate, and the drive cylinder 5 drives the spring 7 to rotate and store energy. After the energy is stored, the operator pulls the handle 22, which drives the drive arm 21 to rotate and compresses the spring 23. The drive arm 21 drives the second pawl 20 to rotate away from the second ratchet 17 through the second mounting shaft 19, thereby causing the second ratchet 17 to lose its limit. Then the spring 7 releases energy, thereby driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the rotating head 9 and the brush head 10 to rotate, thereby performing rotational washing.
