The mist storage tank comprises a tank body, wherein a mist outlet is provided at the front end of the tank body; and the mist storage tank is characterized in that a rear cover is arranged on an inlet provided at the rear end of the tank body, and a mist inlet, an air inlet and an air inlet one-way valve are provided on the rear cover. The air inlet one-way valve is a spiral air inlet one-way valve, the body of the spiral air inlet one-way valve is circular, the diameter of a central opening is not less than the diameter of the inner wall of the mist inlet, the spiral air inlet one-way valve is arranged around the mist inlet, and the thickness of the spiral air inlet one-way valve is gradually reduced from the inner edge to the outer edge. At least three inter-flap openings and at least three flap pieces are provided in the radial direction of the spiral air inlet one-way valve, and a fixed opening is provided on each flap piece. The spiral air inlet one-way valve can reduce the probability of medicine mist particles adhering to the inner wall of the mist storage tank, thereby improving the utilization rate of a medicine, refining the medicine particles, reducing the dispersion amount of the medicine, and improving the delivered dose. In addition, an arranged oxygen pipe interface further has the functions of realizing atomization while inhaling oxygen and reducing the occurrence of the phenomenon of suffocation of a patient.
