[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0025] The present invention provides a sonic cleaning brush, which includes a handle 2, a brush head assembly 1 and a connecting rod 3, wherein the connecting rod connects the handle and the brush head assembly to form a complete cleaning brush.

[0026] The handle has a control circuit board inside and at least one operation key on its surface for providing a start signal. The handle also contains a battery. The control circuit board is connected to the battery and provides power. The operation key is used to enable the control circuit board to supply power to the sonic motor, so that the sonic motor can work. The operation key can be a tactile switch, push button or touch switch, etc.

[0027] The brush head assembly includes a brush head 11 and a brush handle 12. The brush handle contains a sonic motor 6. The brush head and the brush handle are detachably connected, and one end of the brush head is engaged with the drive shaft of the sonic motor. The output of the sonic motor is transmitted to the brush head assembly via the drive shaft. Alternatively, two control circuit boards can be configured: one is a control board located inside the handle, and the other is a drive board located inside the brush handle, used to control the operation of the sonic motor.

[0028] The connecting rod is used to connect the handle and brush head assembly. It has wires inside for connecting the control circuit board and the sonic motor. The connecting rod has a hollow structure and its interior serves as a wiring channel for connecting the sonic motor located inside the brush handle and the control circuit board inside the handle.

[0029] The brush handle is provided with a bracket 4 and a shaft connector 5 detachably connected to the bracket, and a cavity is formed between the shaft connector and the bracket. The front end of the bracket extends to form a support member 41. The support frame is located in the cavity, and its rear end is provided with a mounting bracket 42 for mounting a drive plate of a sonic motor. The sonic motor is located at the front end of the support member.

[0030] A shock-absorbing pad 7 is provided between the acoustic motor and the support to reduce the vibration of the acoustic motor on the brush handle, so that its vibration acts on the brush head.

[0031] The brush head and the brush handle are provided with a plug-in cavity at one end for the machine shaft linkage component to be plugged in and linked. The machine shaft linkage component is inserted into the plug-in cavity 111 and forms a fixed connection with the brush head. At the same time, the brush head and the machine shaft linkage component are detachably connected, which makes it easy to replace different brush heads.
