Description

Technical Field

[0001] The utility model relates to the technical field of waterproof detection, in particular to a sensor structure, a device and a system for real-time sensing of the water leakage position of equipment. Background Art

[0002] The waterproof test is used to determine and evaluate the ability of equipment to withstand the effects of liquid water sprayed, soaked or dripped on it during use. The current waterproof test is to stick waterproof stickers that change color when exposed to water at multiple locations inside the equipment before the test, and then spray or soak the equipment according to the waterproof grade requirements. After turning on the equipment to check whether it can work normally, the equipment is disassembled to check the water ingress and the discoloration of the stickers.

[0003] In the current waterproof test, testers will encounter the following difficulties:

[0004] 1. After the specified test time (12 minutes) of spraying, the device can be disassembled to observe whether water has entered the device under test. It is impossible to confirm from which minute water has entered the device under test.

[0005] 2. The test cannot be stopped in time due to water ingress, and a large amount of water ingress can easily cause damage to the equipment under test.

[0006] 3. When the amount of water inflow is large, the waterproof stickers inside the device under test will change color, making it difficult to determine the initial water inflow location.

[0007] 4. If the function inspection time of the device to be tested is too long after the waterproof test, the small amount of moisture on the internal motherboard will easily evaporate after the heat caused by the operation of the machine, and the situation of a small amount of water entering will be missed after the machine is disassembled for inspection.

[0008] 5. The tester shall select the spacing and quantity of waterproof stickers. If the density of waterproof stickers is small, it is easy for the water inlet point to just avoid the waterproof stickers, resulting in omissions; if the density of waterproof stickers is too large, the tester will have a lot of work to paste waterproof stickers.
