The two ends of the pipe body 2 are a first end and a second end respectively, wherein the first end of the pipe body 2 is connected with the shell 1 and is communicated with the inner cavity of the shell 1, and the second end of the pipe body 2 is used for facing the fan 400.

Therefore, when the fan 400 rotates, negative pressure is formed by the airflow on the periphery of the second end of the pipe body 2 due to the rapid flow speed, and the air in the pipe body 2 can be pumped out under the action of the negative pressure, so that hot air in the shell 1 can be pumped out, and the situation that the electronic device 20 operates at a higher temperature is avoided.

According to the protective shell group 10 provided by the embodiment of the utility model, the shell 1 can be shielded on the outer peripheral side of the electronic device 20, so that the electronic device 20 can be blocked from the outside, and the waterproof and insect-proof functions can be realized. Secondly, the hot air in the shell 1 can be pumped out by means of the pipe body 2 arranged towards the fan 400, so that the ventilation and heat dissipation effects of the protective shell group 10 are good, the temperature rise performance of the electronic devices 20 such as the reactor is improved, the stable operation of the equipment is further ensured, and the potential safety hazard caused by high temperature is eliminated.

In some embodiments, the pipe body 2 includes a first pipe section 21 and a second pipe section 22, the first pipe section 21 is connected between the housing 1 and the second pipe section 22, and the connection of the first pipe section 21 and the housing 1 is higher than the connection of the first pipe section 21 and the second pipe section 22.

The screen can be wire netting, can all be fixed with the screen in body 2 and mounting hole, can supply air to flow out on the one hand by means of the screen, on the other hand can play the effect of separation reptile, mouse etc. and avoid the worm mouse to get into the circumstances that easily causes the short circuit or destroy electronic device 20 in the casing 1.

In some embodiments, a screen is provided at the end of the tubular body 2 intended to face the fan 400, i.e. the screen may be provided only at the free end of the third tubular section 23. Therefore, the blocking of the worm and mouse can be realized from the port of the free end of the pipe body 2, the problem that the pipe body 2 is blocked easily due to the fact that the worm and mouse enters the pipe body 2 is avoided, and further the smoothness of the hot gas discharged through the pipe body 2 is ensured.
