In this embodiment, a rotational adjusting mechanism is provided between the brush head 4 mounting handle 1 and the rotational handle 2 so as to achieve rotatable adjustment of the two, making it convenient for users to adjust the angle of the brush head 4 according to cleaning needs, thereby enhancing the convenience of the use of the present application Specifically, when adjusting, by pressing the adjusting piece 35, the adjusting piece 35 is enabled to push the adjusting tooth 34 to move in the adjusting cavity in a direction away from the adjusting piece 35 (squeezing the elastic member 37 during the movement of the adjusting piece 35 causes elastic deformation of the elastic member 37), thereby releasing the tight clamping fit between the first tooth row 341 on the adjusting tooth 34 and the second tooth row 361 on the cooperating tooth 36. Furthermore, the brush head 4 mounting handle 1 and the rotational handle 2 can rotate relative to each other, achieving the adjustment of the brush head 4. After the user completes the adjustment, the pressing on the adjusting piece 35 is released. At this time, under the elastic force of restoring the elasticity of the elastic member 37, the adjusting piece 35 restores and drives the adjusting tooth 34 to restore, causing the first tooth row 341 on the adjusting tooth 34 to tightly clamp with the second tooth row 361 on the cooperating tooth 36 again, thereby making it impossible for the rotational handle 2 and the brush head 4 mounting handle 1 to rotate.
In a specific embodiment, the middle part of the adjusting cavity is provided with an insertion and avoidance part for inserting the brush head 4 mounting handle 1. The brush head 4 mounting handle 1 is inserted into part of the insertion and avoidance part to divide the adjusting cavity into a tooth moving cavity 32 and an adjusting piece moving cavity 31, the two are in communication via an adjusting hole 33, the adjusting tooth 34 is arranged in the adjusting piece 35 moving cavity, and the adjusting piece 35 is arranged in the adjusting piece moving cavity such that the adjusting piece 35 can pass through the adjusting hole 33 to enter the tooth moving cavity 32 and push the adjusting tooth 34 to move. In this embodiment, it may also be provided between the bottom wall of the tooth moving cavity 32 remote from the adjusting piece moving cavity 31 and the adjusting tooth 34.
In an alternative embodiment, the elastic member 37 can be arranged between the bottom wall of the adjusting cavity remote from the adjusting piece 35 and the adjusting tooth 34. When it is necessary to adjust the angle of the brush head 4, the adjusting piece 35 is pressed so that the adjusting piece 35 pushes the adjusting tooth 34 to move in the adjusting cavity away from the adjusting piece 35 (at this time, the elastic member 37 is compressed and sends an elastic deformation), thereby releasing the tight clamping fit between the first tooth row 341 on the adjusting tooth 34 and the second tooth row 361 on the cooperating tooth 36. Furthermore, the brush head 4 mounting handle 1 and the rotational handle 2 can rotate relative to each other, so as to adjust the brush head 4.
In an alternative embodiment, the elastic member 37 may be provided between the bottom wall of the adjusting piece moving cavity 31 close to the tooth moving cavity 32 and the adjusting piece 35. When the adjusting piece 35 is pressed to move in the direction of the tooth moving cavity 32, the elastic member 37 is squeezed and elastically deforms, so that the pressing on the adjusting piece 35 is released after the user finishes adjusting, and at this time, the adjusting piece 35 is restored under the elastic force of the elastic member 37 restoring elasticity and drives the adjusting tooth 34 to restore. Therefore, the first tooth row 341 on the adjusting teeth 34 and the second tooth row 361 on the cooperating tooth 36 are tightly clamped again, so that the rotational handle 2 and the brush head 4 mounting handle 1 cannot rotate.
In a specific embodiment, the adjusting piece 35 comprises an adjusting pressing part and an adjusting part connected to the adjusting pressing part, and the cross-section of the adjusting piece 35 is T-shaped.
In a specific embodiment, an end part of the first tooth row 341 or the second tooth row 361 is provided with a rotatable part.
