Breakthrough of waterproof test difficulty of multi channel electric toothbrush

Electric toothbrush is a kind of tool which can make the brush head vibrate with high frequency through the rapid rotation or vibration of the motor core to promote tooth cleaning. It can be divided into two types: plug-in power supply and battery drive. But no matter which type of electric toothbrush, its waterproof is very important, whether it is in the production of special waterproof treatment, or in the later period for the product waterproof test, is a safety protection for consumers using electric toothbrush.

For the waterproof test of electric toothbrush, different testing businesses have different methods, but in the face of a variety of types of electric toothbrush, there is little breakthrough in the waterproof test. And Harris technology for different types of electric toothbrush waterproof test always has its own set of solutions. This time we will share a case of multi-channel electric toothbrush waterproof test at the same time for your reference.

1、 Appearance display of electric toothbrush


1. The electric toothbrush is made of waterproof material wrapped inside the electric core. On the handle are the switch button and three circular electricity display areas;

2. The handlebar is connected with the brush head above, and there are obvious marks on it;

2、 Breakthrough of testing difficulties of electric toothbrush and advantages of detector

1. Breakthrough of testing difficulties

(1) Harris technology will customize the mold according to the overall condition of the electric toothbrush, so that the electric toothbrush can be stuck in the mold. This time, it is aimed at the simultaneous detection of three electric toothbrushes. In order to save time, Harris has a special multi-channel detection instrument, as long as the three electric toothbrushes are put into the detection mold below.


(2) The instrument is integrated with the three position tooling. As long as the program is set before testing, the mold under the instrument will close the electric toothbrush to form a sealed environment. The instrument will directly inflate into the mold. When the internal gas reaches the saturation state, the water resistance of the electric toothbrush can be judged by the air pressure inside the mold.


2. Advantages of multi-channel detector:

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

(2) Lower equipment cost; Three channel tightness tester is controlled by one testing equipment, which can save the cost of equipment, and one operator can complete three product tests, which simplifies the manpower for enterprises and optimizes the capital chain of manufacturers.


(3) It has strong operability and high efficiency; The tester is also equipped with "positive and negative" pressure forms and 8 Basic test modes, which can be selected or combined. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols, diversified self-service operation, artificial and intelligent combination, enhance the operability of the device.
