Abstract

A quantitative breathing device which is capable of enabling a person to completely suck target gas comprises a temporary storage device. The lower portion of one side of the temporary storage device is communicated with a gas resource through a connecting port of a normally closed solenoid valve. The lower portion of the other side of the temporary storage device is connected with a respirator through an only-suction valve. The temporary storage device comprises a shell body. A venthole is formed in the upper portion of the shell body, An air bag is arranged in the shell body. The normally closed solenoid valve, a gulp valve and the only-suction valve are respectively fixed on the lower portion of the shell body. A lower limiting switch is arranged in the gulp valve. An upper limiting switch is connected with the shell body above the gulp valve in a clamped mode. The upper limiting switch is connected with the shell body in an up-down sliding mode. A normally open relay and a normally close relay are installed on one side, with the normally closed solenoid valve, of the shell body. The normally closed solenoid valve controls opening and closing of the gas to enter the air bag through automatic control circuits of the lower limiting switch, the upper limiting switch, the normally open relay and the normally close relay.
