Document Type and Number:
WIPO Patent Application WO/2022/205532
Kind Code:
A1
Abstract:
The present invention provides a fixed calculus removing structure, comprising a base body and vibrating heads. Vibrating holes adapting to the vibrating heads are formed in the base body, and the vibrating heads comprise at least two limiting heads and a guide head. By using the limiting and guiding type vibrating head structure, the vibrating effect is more directional, the calculus removing efficiency is enhanced, and the structure is simple and portable to use.
