Problems solved by technology

However, although this assembly process can complete the assembly of the brush head 1 and the drive shaft 8, it still has the following defects: 1. When the heat is transferred from the exposed end of the drive shaft 8 to the internal extension of the drive shaft 8, it needs to consume It takes a long time to transfer to the inner extension end, which increases the assembly time of the brush head and the drive shaft, thereby reducing the assembly efficiency
2. When heat is transferred from the exposed end of the drive shaft 8 to the inner extension end of the drive shaft 8, a part of the heat is released into the air, resulting in unequal temperatures of the heat transferred to the cylindrical surface of the inner extension end, resulting in The material on the cylin

Abstract

The invention discloses an assembly process of an electric toothbrush. The assembly process comprises the following steps: S1, processing a brush head; s2, processing the driving shaft; s3, preliminarily assembling the driving shaft and the brush head; s4, the driving shaft and the brush head are assembled, a worker injects a certain amount of combustion oil into the L-shaped channel, and the combustion oil enters the radial small holes I and the radial small holes II through straight channels of the L-shaped channel; after the combustion oil is injected, the combustion oil is ignited, the combustion oil heats the driving shaft during combustion, the inward extending end of the driving shaft and the limiting plate expand after being heated, at the moment, the material on the cylindrical surface of the inward extending end of the driving shaft expands in the radial direction and extrudes the inner wall of the square blind groove, and meanwhile the material on the cylindrical surface of the limiting plate expands in the radial direction and extrudes the inner wall of the square groove; therefore, the driving shaft is finally assembled on the brush head. The assembly structure has the beneficial effects that assembly is firm and stable, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of assembly of a brush head and a drive shaft in an electric toothbrush, in particular to an assembly process of an electric toothbrush. Background technique [0002] Toothbrush is a kind of brush that is used to clean teeth, belongs to the necessities of people's life. Along with the development of science and technology at present, electric toothbrush appears as new toothbrush form. Surveys show that electric toothbrushes are more scientific and effective than ordinary toothbrushes, and can remove dental plaque, reduce gingivitis, periodontal disease and gum bleeding and other oral diseases, so they are increasingly popular. The electric toothbrush is mainly based on the principle of vibration. The electric toothbrush generates high-frequency vibrations through the rapid electric vibration, and the bristles of the brush head instantly decompose the toothpaste into fine foams, ensuring that the fine foams ...
