On top of the range hoodThe LED light is a small accessory of the range hood. Its main function is to illuminate when the range hood is working.The range hood is in a suction state when working. It will inhale water vapor while sucking and discharging the oil fume. In order to prevent water vapor from damaging the circuit and causing leakage,Therefore, it is necessary to conduct a tightness test on the air tightness of the hood.Hirus Technology has a lot ofLED lights have been tested for air tightness. Today we will share with you how the LED lights on the range hood are tested for air tightness.
The smell of cooking fumes in the kitchen is very strong. The fumes are not only harmful to the health of our family members, but also make it difficult to clean our rooms.So now many families are starting to buy range hoods.Smoking on the hoodAs an accessory on the range hood, the LED light is mainly used for lighting.Generally, the lamp on the range hood is made of a plastic shell, and there is a ring of sealant between the outer lamp shell and the range hood.
What we want to test is whether this layer of rubber ring can be sealed tightly. Since the product is a semi-finished product, Hairis Technology adopts a direct detection method and directly fills compressed air into the product to conduct air tightness testing.
The customer’s testing requirements for the product areIP67 waterproof standard (the product will not get water when it is under one meter of water), so we use a test pressure of 12KPA, which is equivalent to the water pressure that the product will withstand under one meter of water.At the same time, the customer's output is relatively large, so we customized a dual-station non-standard air tightness testing equipment for the customer. One instrument can test two products at the same time.Testing speed is doubled.
Test product steps
The Hairis air tightness tester is simple and convenient to operate, and the entire testing process only takes about ten seconds.
1. The instrument is connected to the power supply and air source interface, and the instrument is in working condition.Set the test parameters and test time according to the product waterproof level requirements and customer needs.
2. Put the test product in and press the start button. The compressed air in the air source will automatically rush into the product, and the instrument will automatically complete the inflation.-Testing-stabilizing a series of steps, the inflation pressure and leakage of the product will be displayed on the instrument. If the product is qualified, the OK light will light up. If the product leaks, the NG light will light up red and sound an alarm.
3. Remove the product and proceed to the next round of testing.
