Structural design method of explosion-proof harmful gas detection fuming cupboard

The invention discloses a structural design of an explosion-proof harmful gas detection fuming cupboard in combination with the current electronic sensing science and technology development trend. The fuming cupboard has the function of detecting the concentration of high-toxicity, flammable and explosive gas in the air in real time, and gas data are fed back to the touch control screen in real time through a sensor data protocol and a built-in algorithm to be rendered and displayed. Meanwhile, the fuming cupboard also has a danger sensing function and an urgent danger avoiding function when an explosion occurs; the function of emergency exhaust after the concentration of combustible and high-toxicity gas reaches a dangerous threshold value can be realized, and the function of driving a stepping motor through a flame/air pressure sensor to enable an explosion-proof vertical sliding door to quickly slide down at the moment of dangerous explosion can also be realized, so that further safety protection is carrie
