A swing angle and its application in tooth surface polishing and bleaching device

Abstract

The invention discloses a swing angle and its application in a tooth surface polishing and bleaching device. The swing angle drives the swing output mechanism through a single handle, which converts the continuous rotation input into a back and forth swing output, so as to achieve a specific obtuse angle steering output. The single-handle drive swing output mechanism can be divided into two types: oblique handle drive and curved handle drive according to its single handle structure and function. The main body of the unit is a portable bleach handle with a built-in battery power source and a detachable swinging angle with dual-function rubber cup attached. The swing angle can also be used alone as a tooth cleaning angle in a dental clinic. The device also comes with a dual-dosage mixing component, which stores polish and bleach separately, and is mixed evenly by the handle power source before use and then applied to the tooth surface; Avoid possible bleach infection when handling.

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 home or clinic for polishing and simultaneously bleaching tooth surfaces and cleaning interdental gaps by swinging and bending back and forth motion output. Background technique [0002] The traditional practice of tooth polishing and bleaching is to treat them separately. This procedure is time-consuming, for which it is beneficial to perform both procedures simultaneously. This background analysis is divided into two parts: a mechanical polishing design and a chemical bleaching design. [0003] A. Mechanical polishing design [0004] Traditional single-use prongs are used to remove tartar and polish tooth surfaces. A polishing head (rubber cup or plastic brush) is connected to the output end of the tooth cleaning angle, and is driven by the dental low-speed handle to rotate with torque. A typical drive mechanism is ...

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
