The utility model discloses an intelligent anti-chemical clothing of built -in temperature and humidity monitoring relates to the technical field of protective clothing, the utility model discloses an intelligent anti-chemical clothing body, the one side of intelligent anti-chemical clothing body is connected with knapsack, the inside fixedly connected with compressed air bottle of knapsack, the inside of intelligent anti-chemical clothing body is provided with intelligent monitoring subassembly, the utility model discloses the control of exhaust valve mechanism has realized the accurate maintenance of the inside micro - positive pressure of anti-chemical clothing, when intelligent monitoring subassembly detects that the air pressure is out of limit, electric push rod starts immediately, and the funnel shape plugging block is separated from the closure block, forms the exhaust passage, and the gas is unidirectionally exhausted through the first check valve, and after the normal air pressure, the electric push rod contracts and makes the plugging block reset seal, and this movement process is through the synergetic effect of electric drive and funnel shape sealing structure, guarantees the exhaust efficiency, prevents the external contaminant reverse osmosis again, improves the protection reliability effectively while maintaining the safe micro - positive pressure.

The utility model discloses a lift car fresh air device for an elevator, and the lift car fresh air device comprises a power generation unit fixedly arranged at the top of a lift car, an energy storage device connected with the power generation unit, and a ventilation system connected with the energy storage device and used for ventilation of air inside and outside the lift car. When the elevator runs normally, the idler wheels make contact with the guide rails, energy is generated through rotation of the idler wheels, and therefore kinetic energy recovery of the elevator is achieved, an additional power source is not needed, energy conservation and environmental protection are achieved, and carbon emission is reduced; therefore, air circulation inside and outside the lift car is achieved, and people trapped in the lift car are prevented from breathing difficulty, faint, faint or other sudden physical conditions caused by unsmooth air circulation in the lift car.
