Problems solved by technology

[0003] Due to the large sealing cavity of this type of mask (the national standard is called dead space), the residual gas exhaled by people remains in it, and is repeatedly inhaled when inhaling, so the oxygen content is low and the carbon dioxide content is high. The temperature rises, making people uncomfortable and feeling suffocated; in addition, the shell is bulky and heavy, which is inconvenient and hinders work

Embodiment Construction

[0040] Reference when using Figure 7 , use a tie to fix the face shell on the nose and upper lip, so that it is close to it. When inhaling, the exhalation valve is closed, and the air enters the latex tube through filtration, and enters the upper lip seal cavity and nostrils through the inhalation valve. The air vent enters the nose; when exhaling, the inhalation valve closes, the exhalation valve valve is flushed open, and the air is expelled out of the shell.

[0041] Due to the small sealing cavity (the national standard is called dead space), the distance between the exhalation valve, the inhalation valve and the nostril is short, the ventilation in the cavity is smooth, the temperature is relatively low, the residual gas is inhaled, the air is fresh, the oxygen content is high, and the carbon dioxide The low content makes people feel comfortable, so it is called the non-suffocating protector.

[0042] The use of the latex tube separates the filter device from the main s...

Abstract

A non-suffocating protective device for the respiratory tract, which is composed of a nose cover body and an upper lip veneer sealing cavity as the main body, with nostril ventilation holes, condensation water penetration holes, exhalation valves, inhalation valves, elastic Lace, equipped with a ventilation duct, and an air filter device. The design of this product is light, convenient and efficient, which greatly reduces the sealed cavity (the national standard is called dead space). High, low carbon dioxide content, relatively low temperature inside the sealed cavity, making people comfortable without feeling of suffocation.

Description

technical field [0001] The invention is an airway non-suffocating protector, which is suitable for the labor insurance industry. Background technique [0002] In addition to the commonly used white multi-layer gauze masks, the respiratory protection products on the market are generally used for dustproof and anti-virus masks with a face mask to seal the nose and mouth. One is to install a lot of ventilation holes on the cover body, and use polyurethane sponge and non-woven fabric (with electrostatic dust collection) as the filter layer inside, and this type of mask that allows the air to enter and exit is called a simple dustproof mask; the other is It is called a reciprocating dust mask with an exhalation valve and an air intake valve dust-proof device installed on the shell, and a reciprocating air mask with an air intake valve anti-virus device (using activated carbon as a filter layer). [0003] Due to the large sealing cavity of this type of mask (the national standard...
