Through the accumulated flow, whether the discharged gas reaches the sum of the volumes of the VOCs in the heating regeneration chamber a and the VOCs in the air purification chamber b which can efficiently regenerate and the formaldehyde adsorption material to the upper wall space of the heating regeneration chamber a or not is judged, and the heating body is closed in real time according to the discharge capacity.
The alarm prompt is that the control processor unit gives an alarm prompt by the buzzer to prompt a user to find fault points in time, wherein the fault points may be that the rotating speed of the fan is slow, the air duct is blocked, or the dust on the coarse filter is too large.
In the pollution discharge process, the heating element is closed according to the pollution discharge amount or is closed according to the set duration, and the purpose is to solve the problem that after the heating element 10 is closed, the temperature in the cabin is pushed forward to be reduced along with the pollution discharge, prevent the waste air which is not discharged from the intervals from the air purification module in the heating regeneration chamber a and the air purification chamber b to the upper wall of the heating regeneration chamber a from being adsorbed by the air purification module again, and further play a thermal desorption role in the air purification module.
