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.

1. Appearance display of electric toothbrush

1. The electric toothbrush is made of waterproof material wrapping the internal battery core. On the handle is a switch button and three circular power display areas;

2. The handheld handle is connected to the brush head above, with obvious alignment marks;

2. Breakthroughs in the detection difficulties of electric toothbrushes and advantages of detectors

1. Breakthrough in detection difficulties

 (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 detection of three electric toothbrushes. In order to save time, Hirays has a special multi-channel detection instrument. Just put the three electric toothbrushes into the detection mold below.

(2) The instrument and the three-station tooling are integrated. As long as the program is set before testing, the upper and lower molds under the instrument will close the electric toothbrush during testing to form a sealed environment.The instrument will directly inflate the mold. When the internal gas reaches a saturated state, the water pressure of the electric toothbrush can be judged by the air pressure inside the mold.

2. Advantages of multi-channel instrument detection:

(1) Save time and cost; this detector can provide three detection channels during testing, and can test three electric toothbrushes at the same time. The testing speed is three times faster than usual, which is more conducive to saving time and cost.

(2) Equipment cost is lower; the three-channel sealing tester uses one testing equipment to control the sealing test of three channels, saving equipment costs, and one operator can complete three product tests, streamlining the manpower for the enterprise and optimizing the manufacturer's capital chain.

(3) It has strong operability and high efficiency; the tester is also equipped with two pressure forms, "positive and negative", and 8 basic test modes, which can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, diversified self-service operations, and combines artificial intelligence with intelligence to enhance the operability of the device.
