Test example of waterproof and breathable film on the back cover of electric toothbrush

In our daily life, we brush our teeth sooner or later to maintain oral hygiene. Now the electric toothbrush is also chosen by most people, because the cleaning ability of the electric toothbrush is stronger, and it is favored by the majority of customers, so the shell of the electric toothbrush also needs to meet the requirements of dust prevention and waterproofThe electric toothbrush needs to touch the water frequently. If the water-proof of toothbrush is not good, it is easy to cause electric leakage or toothbrush damage.

Product to be tested: electric toothbrush back cover

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

Next, let's take a look at how to test the waterproof performance of the waterproof and breathable film on the back cover of the electric toothbrush with Harris technologyTo test the waterproof performance of waterproof and breathable membrane, it is required to be waterproof and breathableUsing the following equipment and methods:

Equipment used: HarrisHWTrue water tester

Detection method: the distilled water is directly acted on the water by the true water testerElectric toothbrush back coverThe test position of waterproof and breathable membrane can simulate the real situation of waterproof and breathable membrane contacting with real water. When water seeps 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
