Mask facilitating breath

Abstract

A mask facilitating breath comprises a mask body, a left ear rope sleeve and a right ear rope sleeve are fixed to the two sides of the mask body, an inner mask cup is arranged on the inner side of the mask body, filtering cotton is installed inside the inner mask cup and connected with an exhaust pipe, a fixed nut is arranged on the exhaust pipe and fixed to the center of the mask body, the exhaust pipe extends out of the mask body, exhaust holes are formed in the outer end of the exhaust pipe, an exhaust valve is arranged inside the exhaust pipe, an exhaust valve body is installed on the exhaust valve, one end of an air inlet pipe is fixed to one side of the inner mask cup, an air inlet valve is installed inside the bottom end of the air inlet pipe, the outer end of the air inlet pipe extends out of the outer side of the mask body, and activated carbon is arranged inside an outer end opening of the air inlet pipe. The air inlet valve is a one-way valve which can only allow entering and not allow leaving, and the exhaust valve is a one-way valve which can only allow leaving and not allow entering. Expiration and inspiration channels are isolated to effectively prevent filtered fresh air inside an air cavity from being polluted by exhalant gas, and the mask of the combined structure can be conveniently detached, cleaned and sterilized and is suitable for being used repeatedly.

Description

Technical field [0001] The invention relates to a breathing filter device, in particular to a convenient breathing mask in which an inner cup, an intake valve and an exhaust valve are installed in the mask. Background technique [0002] Most masks on the market now have improved airtightness in order to better protect against cold and warmth, dust and bacteria, but this not only reduces the ventilation performance of the mask, but also increases the respiratory resistance. Moreover, these masks have only one cavity, resulting in a mixture of exhaled and inhaled gases, which greatly reduces the amount of oxygen inhaled by the wearer every time they breathe, which not only reduces comfort, but also affects health. If the wearer himself suffers from certain bacterial respiratory diseases, he needs to be treated. If he wears a mask, he may even get repeated infections and affect his recovery. Therefore, doctors believe that special populations such as respiratory disease patients, b...

Problems solved by technology

Some people have also invented some masks with breathing valves. Although the exhaust resistance is reduced compared with ordinary masks, it does not fundamentally improve the mixing of exhaled and inhaled gases, and it is inconvenient to clean, so it is not suitable for repeated use.
