Title:
TOOTHBRUSH HANDLE DEVICE AND ELECTRIC TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2022/142174
Kind Code:
A1
Abstract:
A toothbrush handle device (10) and an electric toothbrush. The toothbrush handle device (10) comprises a toothbrush handle housing (100), a battery mechanism (200), a driving electric motor (300), a first buffer member (400) and a second buffer member (500). A mounting cavity (101) is provided inside the toothbrush handle housing (100); the battery mechanism (200) is arranged in the mounting cavity (101) and is connected to an inner wall of the mounting cavity (101); the driving electric motor (300) is located in the mounting cavity (101); one end of the first buffer member (400) is connected to the battery mechanism (200), and the other end thereof is connected to the driving electric motor (300); the driving electric motor (300) is electrically connected to the battery mechanism (200); and the second buffer member (500) is arranged on the inner wall of the mounting cavity (101), and the end of the driving electric motor (300) that is away from the first buffer member (400) is connected to the second buffer member (500). The toothbrush handle device (10) and the driving electric motor (300) are not directly and rigidly connected to the battery mechanism (200) and the toothbrush handle housing (100), and the driving electric motor (300) is actually in a suspended state when working, thereby improving the output efficiency of the driving electric motor (300) and effectively reducing the vibrations transferred to the toothbrush handle housing (100) by the driving electric motor (300), such that the electric toothbrush vibrates less when working.
