Swinging corner and application thereof in tooth surface polishing and bleaching device

Abstract

The invention discloses a swinging corner and an application thereof in a tooth surface polishing and bleaching device. The swinging corner converts continuous rotation input into back-and-forth swingoutput through a single handle-driven swing output mechanism to output in a steering manner at a specific obtuse angle. The single handle-driven swing output mechanism can be divided into an inclinedhandle driving type and a bent handle driving type according to the single handle structure function of the single handle-driven swing output mechanism. A main body of the device is a portable bleaching handle, wherein a battery power source and a detachable swinging corner with a dual-functional rubber cup are arranged in the portable bleaching handle. The swinging corner can also be independently used as a tooth cleaning corner of a dental clinic. The device is further provided with a double-agent mixing assembly for separately storing a polishing agent and a bleaching agent, and the polishing agent and the bleaching agent are uniformly mixed by a handle power source before use and then applied to the tooth surface; and in addition, a personalized oral cavity protection support for protecting gums and lips is further arranged, so that bleaching agent infection possibly caused during operation is avoided.

Description

technical field [0001] The invention relates to the field of dental care devices, in particular to a set of portable electric-driven dental devices used in households or clinics to polish, bleach tooth surfaces and clean interdental gaps at the same time by swinging and bending back and forth. Background technique [0002] Teeth polishing and bleaching have traditionally been treated separately. This procedure is rather time consuming, for which reason it is beneficial to carry out both procedures simultaneously. This background analysis is divided into two parts: a mechanical polishing design and a chemical bleaching design. [0003] A. Mechanical polished design [0004] The traditional disposable tooth cleaning angle is used to remove tartar and polish the tooth surface. A polishing head (rubber cup or plastic brush) is connected to the output end of the tooth cleaning curved angle, and is rotated by the torque driven by the dental low-speed handle. A typical drive me...

AI Technical Summary

Problems solved by technology

First, the production requirements of the small gear structure between the active and passive rotary bodies are high and the cost is high

Second, plastic gears are easy to wear and the meshing will deteriorate rapidly, so the service life is short, so it is not suitable for applications with a long operating time, such as white tooth surfaces

Third, the meshing of gears is prone to heat generation, as well as noise and vibration

Fourth, the gear connection is only suitable for continuous rotation transmission, so the polishing compound is easy to fall out during operation

U.S. Patent 7,060,256 increases the hydrogen dioxide content in the two-part glue, but requires a protective tray to be placed on the tooth surface
