Title:
HANDLE DEVICE AND ELECTRIC TOOTHBRUSH
Document Type and Number:
WIPO Patent Application WO/2022/143915
Kind Code:
A1
Abstract:
A handle device (10) and an electric toothbrush. The handle device (10) comprises a handle housing (100), a battery mechanism (200), a drive motor (300), a first buffer member (400), and a second buffer member (500). A mounting cavity (101) is formed inside the handle housing (100); the battery mechanism (200) is provided in the mounting cavity (101) and is connected to the inner wall of the mounting cavity (101); the drive 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 drive motor (300); the drive motor (300) is electrically connected to the battery mechanism (200); the second buffer member (500) is provided on the inner wall of the mounting cavity (101); and the end of the drive motor (300) away from the first buffer member (400) is connected to the second buffer member (500). The drive motor (300) is not directly rigidly connected to the battery mechanism (200) and the handle housing (100). During an operation process, the drive motor (300) is equivalent to being in a suspended state; therefore, the output efficiency of the drive motor (300) is improved, and vibration transmitted to the handle housing (100) by the drive motor (300) is effectively reduced, such that the electric toothbrush generates small vibration during operation.
