With the improvement of people's security awareness, a complete set of visual smart homes has gradually entered people's field of vision, and smart doorbells are the first roadblock to intercept criminals.

In order to ensure the normal use of smart doorbells and prevent them from being affected by splashing water or other means, manufacturers should provide waterproof protection for the doorbells.

So how do they know that the product is waterproof?This requires doing a doorbellWater resistance test。

Waterproof testing is generally divided into two types, one is to directly soak in water, and the other is to use compressed air to test through air tightness testing equipment.

Compared with traditional water immersion testing, air tightness testing does not require wiping water after testing, which is more efficient.

Below, Hirays Technology will show youSmart doorbell air tightness detectioncase.

Customers require that the waterproof performance of their smart doorbell products can reach IP68 waterproof level.

Equipment used for air tightness testing: HC Classic SeriesAir tightness detector

Testing method: Direct testing is adopted. According to the shape and structure of the smart doorbell, a sealing ring + mold is used to seal the product to be tested so that it forms a closed cavity during testing.

Put the smart doorbell into the mold for testing.The test pressure is 12Kpa ,The maximum allowable leakage is 50pa. The air intake time is 10s, the pressure stabilization time is 15s, the test time is 8s, and the deflation time is 1s.

As a result, the equipment automatically determines that if the leakage value does not exceed 50pa, the tested product passes the waterproof test, otherwise it fails and the tested product is defective.
