Problems solved by technology

[0002] In the prior art, because electric toothbrushes have multiple modes, in order to facilitate users, generally electric toothbrushes are provided with an indicator panel on the handle, and the handles of existing electric toothbrushes are generally set to a simple indicator light mode, which is directly set on the plastic handle. Make a few holes and put LED lamp beads and fill them with transparent substances, and then mark the text under the lamp holes, making consumers feel crude and difficult to be elegant. In order to improve the appearance of electric toothbrushes, it is urgent to fundamentally improve the electric toothbrush. The processing technology of the handle indicator panel is improved

Abstract

The invention relates to the technical field of electric toothbrushes, in particular to an electric toothbrush handle laser etching process.The process includes the following steps of firstly, injection molding, wherein a resin layer is arranged on a handle light source area through injection molding and is a transparent body or a semitransparent white body; secondly, electroplating, wherein a metal layer or a metal oxide layer is arranged on the resin layer through vacuum electroplating; thirdly, laser etching, wherein the metal layer or metal oxide layer is hollowed out to form a required shape through laser etching; fourthly, spraying, wherein gloss oil is sprayed on the metal layer or metal oxide layer and then cured.The prepared product abandons the simple and crude mode of an existing indicator lamp on the aspect of appearance, and the metal texture, smoothness, light permeability and science and technology feeling of an electric toothbrush handle indication panel are enhanced; the process is bold and innovative and is combined with the vacuum electroplating and laser etching technology for machining the product of a structure with the resin layer, the metal layer or metal oxide layer and the gloss oil layer, steps are simple, machining patterns are variable due to the laser etching technology, and different production requirements can be met.

Description

technical field [0001] The invention relates to the technical field of electric toothbrushes, in particular to a laser engraving process for a handle of an electric toothbrush. 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 and put LED lamp beads and fill them with transparent substances, and then mark the text under the lamp holes, which makes consumers feel crude and unrefined. In order to improve the appearance of electric toothbrushes, it is urgent to fundamentally improve the electric toothbrush The processing technology of the handle indicating panel is improved. Contents of the invention [0003] The object of the present invention is to address the above-mentioned shortcomings in the prior art, and provide a laser engraving process for an electric toothbrush handle that combines t...
