the transmission member 122 has a propping structure 125, which is used for sequentially propping two sidewalls of the transmission hole 124 perpendicular to the direction of the transmission rod 20 when the transmission member 122 is driven by the motor 121 to rotate, so as to drive the transmission rod 20 to swing with the positioning protrusion 32 as a fulcrum.
The power assembly 12 includes a motor 121, a transmission member 122 and a limit bearing 123, wherein the limit bearing 123 is used for limiting the position of the transmission member 122, and the transmission member 122 is driven to rotate at a high speed by the motor 121. When the transmission member 122 rotates at a high speed, the abutting structure 125 disposed on the outer wall of the transmission member 122 sequentially presses the two side walls of the transmission hole 124, so as to drive the transmission rod 20 to rotate at a high speed with the key 30 as a fulcrum, thereby cleaning the teeth. The electric toothbrush 1 disclosed by the invention only swings the bristle component 18 when in use, the mounting head 16 cannot swing, and the use comfort level is high; meanwhile, the transmission rod 20 is adopted to transmit power, so that the thickness of the mounting head 16 is reduced, and teeth can be cleaned deeply; when the bristle component 18 is replaced, the electric toothbrush head 10 does not need to be completely replaced, and the use cost of the electric toothbrush 1 is reduced.
In short, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
