Self-breathing self-charging type mask

Abstract

The invention discloses a self-breathing self-charging type mask which is mainly formed by a mask body, an air supply body, an air draft body, a fan, a small generator, a rechargeable battery, a filter membrane and a mask front cover. Square holes are formed at two sides of the mask body to be used for matching with the air supply body, a hollow cylinder is arranged at the front part of the mask body, the hollow part of the hollow cylinder communicates with the inner chamber of the mask body, support ribs are arranged in the hollow cylinder to be used for supporting the filter membrane at the front end; and a headband is arranged on the mask body to be used for fixing the mask body. The air draft body can timely discharge exhaled air and send fresh air to the nasal cavity, so that a wearer can smoothly breathe; the air supply body sends air into the mask body via air vents, so that the air cannot directly blow to the face of the wearer, thus preventing the wearer from catching cold and preventing dry skin; and the generator can converter residual air of the air supply body and air exhaled by the wearer into electric energy to be charged to the battery of the fan, thus increasing the one-time use time of the mask and saving energy.

Description

technical field [0001] The invention relates to a mask, in particular to a self-breathing and self-charging mask. Background technique [0002] With the normalization of smog weather, anti-smog masks have become a must-have for people to travel. Anti-smog masks can effectively filter visible or invisible substances such as PM2.5 particles and pollen in the air, provide people with a safe breathing microenvironment, and effectively protect people's respiratory health. However, while the anti-fog and haze masks currently on the market effectively filter harmful substances in the air, their breathing resistance also increases accordingly, making people not breathing smoothly and feeling suffocated. Long-term wearing has certain damage to the wearer's alveoli, especially It is the elderly and children who have a greater impact. In order to make wearing more comfortable, Patent No. CN103919304B discloses an "active air supply mask", which mainly has a fan to continuously supply...
