Wireless doorbell does not need wiring, installation is simple and convenient, welcomed by modern families. As an electronic product, doorbell is usually waterproof in order to increase its service life. This time, Harris tested the sealing performance of this doorbell for customers.
It can be seen from the following products that the doorbell shell is a roll of plastic products with some openings on it.
It can be seen from the picture that the doorbell shell is a semi-finished product with an open structure on one side and some holes on the top. When we test the tightness of the doorbell shell, we need to seal one side of the doorbell with silica gel, and the holes on it also need to be sealed with silica gel, so as to form a sealed space inside the product, and then we can test its tightness. There are two kinds of test methods, direct test and indirect test. Direct test is to test the internal gas of the product directly, and judge the sealing performance of the product by observing the change of the internal gas of the product. If the product is a finished product without inflation port, it needs to make a mold according to the shape of the product, seal the product, inflate the mold, and observe the air pressure change between the product and the mold to judge whether the product leaks. This test method is called indirect test.

Different test methods can be selected according to the structure of the product, whether there is air filling port or not, and the size of the product to realize the sealing and waterproof test of the product.
