As an optimization scheme of embodiment 1, the utility model further provides embodiment 2, and on the basis of applying embodiment 1, the electronic equipment box further includes a plug, the plug is fixedly connected with the outer surface of the box body 100 through a connecting piece (not shown in the figure), the vent 111 is closed by the plug, and the movement direction of the push rod mechanism 300 is opposite to the plug. At this time, the end of the push rod mechanism 300 does not have a function of closing the vent, but functions as a plug that has better sealing performance than the push rod mechanism 300. Specifically, the connecting piece is steel wire, so that the plug is prevented from being broken and flown by pressure, and the safety is improved.

Wherein, an end cover is further provided on the case 100, and the end cover is used for closing the opening at the top of the case 100 after the corresponding components such as the circuit board and the push rod mechanism 300 are installed, and the case 100 can be detachably connected with the end cover.

The electronics box further includes a guide 500, and the guide 500 is fixed to an inner wall of the box corresponding to the explosive region 110, so that the pushing link 320 pushes the plug away from the vent 111.

If the failed explosive electronic 130 generates a combustible gas, the detection device transmits a signal to the controller, or the detection device senses that the pressure of the explosive region 110 rises above a limit value, the controller moves the push rod 310 downward, and pushes the connecting rod 320 and the second end 312 of the push rod 310 to push the second plug 400B and the first plug 400A apart at the same time. The air circulation device 500 is opened, at this time, the second air port 111B is used as an air inlet, the first air port 111A is used as an air outlet, and the air channel formed by the partition board 200 and the air channel 131 accelerates the exchange speed of the air inside the box 100 and the external air, enhances the air exchange circulation, and enables the concentration of the combustible gas inside the box to be rapidly reduced to a safe range and be completely dissipated. Specifically, the gas flow device 500 is a fan, and the detection device may include a gas sensor and a pressure sensor.
