[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figure 1-Figure 3 As shown, a sonic toothbrush comprises a handle 1, a brush head 2 and a charging stand 3. A driving plug 13 is arranged on one side of the top of the handle 1. A motor and a battery are arranged in the handle 1. An operating panel 11 is arranged on the handle 1. A controller is arranged in the operating panel 11. The driving plug 13 is connected to the output shaft of the motor. The battery is connected to the operating panel 11 and the motor. The motor is controlled by the operating panel 11. The brush head 2 comprises a brush rod and bristles. The bristles are fixed to one end of the brush rod. A slot is provided at the end of the brush rod away from the bristles. The slot is detachably connected to the driving plug 13, which is convenient for replacing the brush head 2. The bottom of the handle 1 is movably connected to the charging stand 3. After the connection is completed, the charging stand 3 can charge the battery with an external power supply. At least one arc groove 12 is provided on the side of the handle 1 away from the operating panel 11, preferably two arc grooves 12 are provided.
