Ventilation method of automatic-ventilating mouth muffler and mouth muffler ventilator

Abstract

The invention discloses a ventilation method of an automatic-ventilating mouth muffler and a mouth muffler ventilator. The ventilation method comprises the following steps that (1) the mouth muffler is arranged; (2) the mouth muffler ventilator is arranged; (3) a user wears the mouth muffler, opens a bar-shaped opening of the mouth muffler ventilator through a rotary switch, and controls a drive motor to rotate through a single chip microcomputer controller; (4) when the user exhales, the drive motor drives fan blades to rotate so as to discharge exhaust gas which is exhaled out of the human body and located between the mouth muffler and the human body; (5) when the user inhales, the drive motor stops rotating or the rotating speed is decreased, and external air enters the mouth muffler through filtering materials of the mouth muffler; and (6) automatic ventilating of the mouth muffler is achieved. The invention further discloses the mouth muffler ventilator. By adoption of the ventilation method of the automatic-ventilating mouth muffler and the mouth muffler ventilator, the exhaust gas exhaled by the human body can be pumped out of the mouth muffler and the nose of the user, air between the mouth muffler and the face can be kept dry and cool easily, and respiratory and wearing discomfort caused by damp and stuffiness is avoided.

Description

technical field [0001] The invention relates to the technical field of masks, in particular to a ventilation method for active ventilation masks and a mask ventilator for implementing the method. Background technique [0002] Mask is a common daily necessities in life, it can block harmful particles, gases, odors, droplets from entering and exiting the wearer's mouth and nose. [0003] In the current society, with the development of industrialization, the popularization of automobiles, the increase of germs, and the pollution of heavy metals, the air pollution has become more and more serious. Formaldehyde has exceeded the standard in many areas, and the haze weather has increased, which is very harmful to human health. PM2.5 in northern and other areas seriously exceeds the standard. With the increasingly serious haze weather, the damage to human health, especially the respiratory tract, is becoming more and more prominent. Masks have almost become a must-have when going ...
