Title:
OSCILLATION MECHANISM AND ELECTRIC HEATER
Document Type and Number:
WIPO Patent Application WO/2020/186725
Kind Code:
A1
Abstract:
The present application provides an oscillation mechanism and an electric heater. The oscillation mechanism comprises a base adapter (13), a motor frame (4), and a housing (1) fixed to the motor frame (4). The oscillation mechanism further comprises a friction ring (11) and a friction frame (12). The friction ring (11) is fixedly connected to the motor frame (4), the friction frame (12) is fixedly connected to the base adapter (13), and the friction ring (11) is attached to an upper surface of the friction frame (12) and is slidable relative to the same. The present application effectively omits a structure of balls and a ball bearing frame, and changes a point-contact configuration into a surface-contact configuration, so as to enable oscillation portions to have a more stable contact without suffering from instability issues such as detachment, and to effectively reduce the number of components, improve assembly and disassembly efficiency, and reduce overall machine costs.
