Title:
MULTIFUNCTIONAL ELECTRIC TOOTHBRUSH POWER HANDLE
Document Type and Number:
WIPO Patent Application WO/2023/241533
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electric toothbrushes, and particularly, to a multifunctional electric toothbrush power handle. The multifunctional electric toothbrush power handle comprises a handle body, a control mainboard, a brush rod, a battery assembly, and a transmission structure. The transmission structure comprises a driving motor, a gear assembly, a main transmission rod, a driven rod, and a supporting frame. The main transmission rod is provided with a transmission cavity. The driven rod is arranged through the transmission cavity. The driving motor drives the gear assembly to actuate a crankshaft assembly to rotate, such that the crankshaft assembly drives the main transmission rod and the driven rod to extend and retract. The bottom of the main transmission rod is connected with the gear assembly. The gear assembly is further configured for driving the main transmission rod to swing laterally. The brush rod sleeves the end of the main transmission rod distal to the handle body. Accordingly, the present invention solves the problem that the brush head of existing electric toothbrushes cleans teeth in only one direction and requires continuously rotating the handle in use. The present invention also eliminates the need for moving the handle laterally when cleaning different parts of a tooth, which may lead to poor user experience.
