​Waterproof performance is the most basic quality requirement for electric toothbrushes, and it is also the highlight and selling point of electric toothbrushes.Electric toothbrushes are daily necessities that are exposed to water. Once water enters, the circuit board inside will short-circuit, which may cause the product to be scrapped or lead to other safety accidents. Therefore, manufacturers conduct strict waterproof tests on electric toothbrushes.Not long ago, an electric toothbrush manufacturer approached Hirays Technology for a waterproof testing solution, hoping to use our instruments to test the waterproofness of electric toothbrushes. The following is an introduction to the solution.

one.Customer’s Electric Toothbrush Waterproof Testing Requirements

After in-depth communication with the customer, Hiraysi Technology learned that the customer needs to test and identify the IP67 waterproof level of the electric toothbrush. Secondly, it requires testing without causing damage to the appearance and electronic components of the electric toothbrush.

two.Difficulties in testing the waterproofness of electric toothbrushes

This customer's electric toothbrush is fully sealed, which makes the overall waterproof performance better. However, it also brings a certain degree of difficulty to the waterproof test. If high-precision testing is to be achieved, a powerful monitoring system is required to assist in detecting small leaks from the electric toothbrush.

three.Specific solutions

Hirays Technology uses compressed air as the detection medium to conduct waterproof testing of electric toothbrushes by detecting changes in air pressure. Because the electric toothbrush is fully sealed and has no inflation port, we customized a specific mold and tooling for it. In addition to assisting in testing, the mold also protects the appearance of the product.

This set of testing equipment originally has a very small internal space (1.5CC) and is equipped with an imported high-sensitivity pressure sensor with a detection accuracy of up to 0.1Pa. Bubbles as big as a pinhole leaking every minute can be detected without fail.The detection time is between 5-8 seconds, which meets the requirements of low detection cost and high detection efficiency.

The tester records a variety of waterproof level testing parameters and is not limited to one waterproof level test.It can support leakage test methods such as leakage test, obstruction test, positive pressure test, and negative pressure test.

five.Electric toothbrush waterproof test related functions

1. Using a large-size touch screen as the human-machine interface, you can easily monitor the test results and set various parameters during the waterproof test process.

2. It has an alarm function for qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misdetection.

3. With 4-channel switch input and 8-channel relay output, it can be controlled by external sensors and switch buttons, and can control external relays, solenoid valves and other actuators, conveniently realizing full automation of testing.

4. The tester has 200 user subroutines. By setting the subroutine parameters on the touch screen, the user can connect different subroutines in series to form a test process. Through the I/O interface of the leakage meter, the leakage meter can accept control signals from external sensors and control external actuators (relays, solenoid valves, etc.).Thereby automating the testing process.

5. It has a test data recording function, and the test data can be downloaded to a USB flash drive and displayed on the computer.

6. It has barcode scanning function, which can track and record defective products and repair status; host computer function, etc.
