[0003] In the application number "201520413961.5", the "outdoor sports camera with waterproof and dustproof function" is disclosed. This application solves the problem that it is difficult to take pictures with underwater special effects due to outdoor conditions during existing shooting. However, the application does not have a relevant sealing detection mechanism for water entering the upper shell of the camera. In practice, the camera requires external signals and power supplies, and many components are exposed to the camera, resulting in weak waterproof and dustproof functions of the camera. This greatly shortens the life of the camera and may cause the risk of camera failure. In addition, when the camera is flooded, the user needs to disassemble the camera for inspection to confirm whether water has flowed into the interior of the camera, which is inconvenient.

[0015] Beneficial Effects

[0016] The utility model provides a MIPI camera with dustproof and waterproof mechanism. Compared with the prior art, it has the following beneficial effects:

[0017] In the utility model, through the provided sealing detection mechanism, the user can regularly pull the pull rod to pull out the water storage box and check whether there are traces on the test paper. When water enters from the outside, water enters the interior of the upper shell of the camera and flows into the provided drainage groove. The water in the drainage groove flows into the test paper and may leave traces on the test paper. When traces are left, it indicates that there are gaps between the upper flexible printed circuit board and the upper shell lead-out notch and the lower shell lead-out notch, and the sealing performance is poor. Subsequently, the water flows into the water-absorbing pad, which absorbs the water and can prevent water from damaging the PCBA assembly. In addition, the waterproof rubber ring blocks the upper shell lead-out notch and the lower shell lead-out notch, and can prevent a certain amount of water from entering the upper shell of the camera. The provided sealing groove and the sealing rubber ring can make the upper shell of the camera and the lower shell of the camera tightly connected, prevent water from being contaminated by the PCBA assembly, and play a role in dust prevention. At the same time, the provided PCBA edge protection pad can play a certain protective role, and multiple fastening screws can enhance the tight connection between the PCBA assembly and the upper shell of the camera.
