In daily life, we brush our teeth sooner or later to maintain oral hygiene. Nowadays, electric toothbrushes are also chosen by most people because they have stronger cleaning capabilities and are favored by customers. Therefore, the casing of electric toothbrushes also needs to meet dustproof and waterproof requirements.。Electric toothbrushes need to be exposed to water frequently. If the waterproofing of the toothbrush is not done well, if water enters, it will easily cause leakage or damage to the toothbrush.

Product to be tested: Electric toothbrush back cover

There is a charging system inside the electric toothbrush, and the outside must be in contact with water during use, but water must not be allowed to enter the inside from the outer shell.The waterproof and breathable film on the back cover of the electric toothbrush is very necessary.

Next, let’s work with Hirays Technology to see how to test the waterproof performance of the waterproof and breathable membrane on the back cover of an electric toothbrush. What the customer requested this time isTest the waterproof performance of the waterproof and breathable membrane, requiring waterproof and breathable, using the following equipment and methods:

Equipment used: HiraysHWReal water tester

Testing method: The real water tester applies distilled water directly toElectric toothbrush back coverThe waterproof and breathable membrane test position simulates the actual situation of the waterproof and breathable membrane actually contacting real water.When water seeps out from the other end of the waterproof and breathable membrane, the leakage value on the instrument will be very large.The leakage value will be set according to the actual situation of the product。

HW-PF1010It is an instrument specially developed by Hirays for the real water test of waterproof and breathable membranes. It not only has the function of generating simulated test water pressure, but also can automatically identify whether the waterproof and breathable membrane is leaking under the action of simulated water pressure. The measurement results can be quantified, which improves the current shortcomings of manual confirmation and enables automated testing and judgment of products with waterproof and breathable membranes.Production has become possible, improving efficiency for our customers while also ensuring product quality.
