Breakthrough in the waterproof detection of multi-channel electric toothbrushes-Hiraysi Technology

An electric toothbrush is a tool that uses the rapid rotation or vibration of an electric movement to cause the brush head to vibrate at high frequencies to promote tooth cleaning. It can be divided into two types: plug-in and battery-driven.But no matter what type of electric toothbrush, its waterproofness is very important. Whether it is special waterproof treatment during production or waterproof testing of the product in the later stage, it is a safety protection for consumers when using electric toothbrushes.

Different testing companies have different methods for testing the waterproofness of electric toothbrushes, but there are few breakthroughs in testing the waterproofness of various types of electric toothbrushes.Hirays Technology always has its own set of solutions for testing the waterproofness of different types of electric toothbrushes.This time we will share a case of simultaneous waterproof testing of multiple electric toothbrushes for your reference.

one,Appearance display and detection difficulties of electric toothbrushes

1. This time there are three electric toothbrushes to be tested for waterproofness. They are all cylindrical handgrips made of waterproof materials wrapped with internal batteries, plus irregular-shaped brush heads, with obvious docking interfaces;

2. There are three circular power display areas on the electric toothbrush handle. Above is the switch button. The fully enclosed waterproof structure and special shape cannot be fixed during testing for direct testing.

2. Breakthroughs in the detection difficulties of electric toothbrushes and the detection process

1. Hirays Technology will customize the mold according to the overall condition of the electric toothbrush, so that the electric toothbrushes can be stuck into the mold. This time, it is aimed at the simultaneous inspection of three electric toothbrushes. In order to save time, Hirays has a special three-station inspection tooling. As long as the three electric toothbrushes are put into the mold respectively, and the inspection starts, the upper and lower parts of the mold will close the electric toothbrushes to form a sealed environment around them.

The instrument is integrated with the three-station tooling. As long as the program is set before testing, the instrument will inflate the mold during testing.If the electric toothbrush is not sealed and air leakage occurs, the leakage value displayed in the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the wire connector is leaking, and the instrument test result will also show NG, which means the air tightness test failed.If the tested wire connector does not leak, the gas in the tooling mold will be in a constant state after inflation. The pressure value and leakage value displayed on the instrument are also stable. The instrument test result will display OK, indicating that the air tightness test has passed.
