Problems solved by technology

[0002] In the prior art, because electric toothbrushes have multiple modes, in order to facilitate users, generally electric toothbrushes will be provided with an indicator panel on the handle. Make a few holes, put LED lamp beads and fill them with transparent substances, and then mark text under the lamp holes, which makes consumers feel crude and unrefined. Can clearly see the text), but the basic one-piece processing mode, if there are errors or omissions in the processing process, it is very easy to cause the entire electric brush to be scrapped, which is extremely risky

Abstract

The invention relates to a production process for an electric toothbrush, in particular to a production process for an electric toothbrush casing. The production process comprises the steps that firstly spraying is conducted, specifically, a shading light oil layer is sprayed on the front or the reverse of a transparent decorating part; secondly laser engraving is conducted, specifically, the laser engraving technique is adopted and the a needed shape is hollowed out on the shading light oil layer; thirdly electroplating is conducted, specifically, a metal layer or a metallic oxide layer is vacuum plated on the front of the transparent decorating part; fourthly injection molding is conducted, specifically, a transparent soft rubber layer is injected on the light source region of an electric toothbrush handle; and fifthly assembling is conducted, specifically, the transparent decorating part is assembled on the transparent soft rubber layer and the reverse of the transparent decorating part is attached to the transparent soft rubber layer. According to the production process, processing risk sharing is achieved; the loss cost caused by processing errors is lowered; and the implicit glowing effect is achieved, and the lighting effect is even and gentle.

Description

technical field [0001] The invention relates to a manufacturing process of an electric toothbrush, in particular to a manufacturing process of an electric toothbrush shell. Background technique [0002] In the prior art, because electric toothbrushes have multiple modes, in order to facilitate users, generally electric toothbrushes will be provided with an indicator panel on the handle. Make a few holes, put LED lamp beads and fill them with transparent substances, and then mark text under the lamp holes, which makes consumers feel crude and unrefined. Can clearly see the text), however, the basically integrated processing mode, if there is an error or omission in the processing process, it is very easy to cause the scrapping of the entire electric brush, which is extremely risky. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings in the prior art, and to provide a manufacturing process for a risk sharing ...
