Description

Convenient dual air valve dual channel depth gas mask

technical field

The utility model mainly relates to the field of protective equipment, in particular to a convenient double-air valve double-channel deep gas mask.

Background technique

The human body exchanges substances with the outside world all the time. The largest and most frequent exchange is the respiratory system. The spread of bacterial and viral diseases is mainly caused by the inhalation and exhalation of bacteria and viruses through the mouth and nose. . Wearing a mask is an important measure to control the import and export of germs and viruses. Due to the constraints of various factors, traditional masks cannot be perfect. For example, if the mask is too thick, it affects ventilation, and it is easy to leak air at the edge of the mask when breathing, which cannot achieve sufficient protective effect; while the mask is too thin to achieve a protective effect . Moreover, when the current mask is in use, both the exhalation and the inhalation are in the area covered by the mask and the mouth and nose. Due to the isolation effect of the mask on the gas, the exhaled turbid gas cannot be completely discharged, thereby reducing people's breathing efficiency and causing breathing. not smooth. Because the mask body has a filter layer, it can only be an opaque design.

A ducted exhaust fan is connected in series on the exhalation pipe.

A ducted suction fan is connected in series on the suction pipe.

Both the exhaust fan and the suction fan have the effect of promoting the flow of air, thereby saving the power of exhalation and inhalation, and promoting breathing efficiency.

The protective cover body is a transparent 3D mask, a protective mask or a gas mask.

The protective cover can be any equipment to protect the mouth and nose. When the protective cover is a mask, a three-dimensional mask is appropriate.

The protective cover body is a 3D mask made of hard transparent material.

The 3D mask made of hard transparent material will not be deformed due to exhalation and inhalation during use, which can avoid the generation of gaps in the area where the face fits, and ensure a good protective effect.
