Oral electric cleaner

Abstract

The invention discloses an oral electric cleaner. The oral electric cleaner is characterized by comprising comprises a handle outer shell, an insulating inner shell, a motor, a speed change mechanism,a transmission shaft sleeve, a transmission shaft, a hose, a steering transmission mechanism, an angle adjusting mechanism and an eccentric joint; an output end of the motor is connected with the transmission shaft through the speed change mechanism; the steering transmission mechanism comprises an input shaft, an input shaft bracket, an input cross shaft, an intermediate shaft, an output shaft,an output shaft bracket and an output cross shaft; the input shaft bracket is connected with the output shaft bracket through the angle adjusting mechanism; the angle adjusting mechanism comprises a connecting rod, a first gear, a second gear, a first hinge shaft, a second hinge shaft and a screw. The oral electric cleaner disclosed by the invention can simultaneously meet the performance requirement that the input shaft can still drive a cleaning head to normally work after an angle and a direction of the output shaft are adjusted.

Description

technical field [0001] The invention relates to an oral electric cleaner. Background technique [0002] The focus of oral cleaning is to control bacterial plaque, eliminate dirt and food residues, enhance physiological stimulation, and make the oral cavity and dental system have a clean and healthy environment, so as to exert their physiological functions and maintain oral health. [0003] And be used for the electric type cleaner (household or medical) that cleans such as tooth, gum, tongue coating, interdental space at present. See figure 1 , the electric cleaner has a motor, an input shaft, a driving bevel gear, a driven bevel gear, an output shaft, and a cleaning head. When working, the motor drives the input shaft to rotate, and the input shaft drives the driving bevel gear to rotate. The driving bevel gear The driven bevel gear is driven to rotate, the driven bevel gear rotates coaxially with the output shaft, and the cleaning head is eccentrically mounted on the out...

AI Technical Summary

Problems solved by technology

However, there are following deficiencies in use: in order to ensure the normal transmission and motion requirements, the axial direction of the output shaft cannot be changed, so there is a problem that the angle and direction of the cleaning head cannot be adjusted; and due to different positions in the oral cavity (such as teeth, When cleaning different parts such as gums, gaps between teeth, tongue coating, etc., the cleaning head is actually required to change the direction and angle, but the existing structure cannot meet the requirements that the input shaft can still drive the cleaning head to work normally after the angle and direction of the output shaft are adjusted at the same time. performance requirements
