According to the stress state difference of two diaphragms, the utility model discloses an air feed under continuous and pulse two kinds of modes.
One, continuous air supply mode
As shown in fig. 1 and fig. 6, two paths of oxygen are output from a decompression chamber 308 arranged inside the valve body, and the first path of oxygen reaches the air outlet convex nozzle 34 of the air outlet unit 12 after passing through the first air passage 306; the second path passes through the second air duct 307 to the switching plate 14.

Wherein a highly sensitive perception of the inspiratory action of the human body can be achieved by changing or selecting the parameters of the suitable adjusting elastic element 22, i.e. the spring.
When the human body stops inhaling, the force of the adjusting elastic element 22 causes the inhaling diaphragm 21 to descend, and the air hole of the inhaling convex nozzle 33 is covered and sealed, and the state is returned to the state shown in fig. 4. The air pressure on the upper end face of the air outlet diaphragm 20 is recovered, the stress on the upper end face (back face) is larger than the stress on the lower end face (front face) to seal the air outlet convex nozzle 34, and oxygen supply is stopped.
The circulation is repeated, and the oxygen supply module controls the air outlet and the air outlet to be closed according to the breathing frequency of the human body, so that the pulse oxygen supply function is realized, and the purposes of saving oxygen and prolonging the oxygen use time are achieved. Practical tests prove that the gas using time of the pulse function is 3 times of the direct-current gas discharging time under the condition of ensuring the consistency of the oxygen concentration, and the oxygen using effect is greatly improved.
