Nose warming type respirator mask and air distribution method

Abstract

The invention relates to a nose-warming breathing mask and an airflow organization method, comprising an outer packaging layer and fixing lines, the fixing lines are symmetrically arranged on the left and right sides of the outer packaging layer, and a nasal cavity module and a double-layer hose are arranged inside the outer packaging layer. The nasal cavity module has an open structure on the rear side of the outer layer of the package. One end of the double-layer hose is connected to the nasal cavity module, and the other end is an opening leading from the outer layer of the package. The double-layer hose is divided into suction and Channel and exhaust channel, the double-layer hose and hose compartment are made of heat-conducting materials, the suction channel is located at the rear side of the exhaust channel, close to the face of the human body, there is a suction one-way valve inside the suction channel, and the exhaust An exhaust one-way valve plate is arranged inside the air channel. The invention solves the problem of blocked air circulation between the inside of the mask and the outside of the mask, and uses the temperature of the exhaled gas inside the exhaust channel and the temperature of the human body to warm the cold fresh air inside the inhalation channel, thereby ensuring that the patient can breathe warm all the time. Hot fresh air.

Description

technical field [0001] The invention belongs to the technical field of masks, and in particular relates to a warm-nose breathing mask and an airflow organization method. Background technique [0002] In winter, in order to resist the invasion of cold wind, especially those suffering from inflammation of the mouth and nose or a cold often choose masks as a thermal protection tool, but traditional masks only protect the mouth and nose from the cold wind, but ignore the inner and outer parts of the mask. The air circulation between the outside of the mask is blocked, and people often inhale the foul gas they just exhaled, threatening their health. Therefore, through a new type of airflow organization, the new respirator designed according to this method can not only resist the invasion of cold wind, but also ensure that personnel can breathe fresh air at all times and avoid the secondary harm caused by the gas just exhaled. . SUMMARY OF THE INVENTION [0003] The technical ...
