Abstract

The invention discloses an air filtering mask, which comprises a mask body, a ventilating chamber with an upward opening is arranged at the left and right ends of the mask body, and an air filtering mechanism for filtering air is provided in the ventilating chamber. The mask has the function of automatic wearing. By installing the elastic wearing belt and the cooperation with the retractable breathing mask, the mask can be automatically worn on heads of various sizes, which greatly improves the efficiency and scope of application when wearing the mask. The structure of self-filtering air and intermittently updating the air in the mask can effectively ensure the purity of the air inhaled by the wearer and improve the utilization rate of the air in the mask. When filtering the air, the mask can pass through the inhaled air. The wind automatically senses the working status of the filter plate and automatically replaces the filter plate that has lost its filtering function, so as to continuously maintain the mask’s ability to filter air, so that the wearer can continue to use the mask for a long time.

Description

technical field [0001] The invention relates to the field of filtration, in particular to an air filtration mask. Background technique [0002] People's normal life and work are inseparable from the air. When living and working in an environment with a lot of dust in the air, pure air is more needed. Generally, the air is filtered through a mask to ensure that the inhalation contains less dust. Air. [0003] At this stage, most masks need to be worn manually. When facing people with different head sizes, it may be inappropriate to wear them. The general mask only has a simple air filtering function and cannot be used on the filter plate. When there is a lot of dust accumulated on the mask, the filter plate is automatically replaced, which greatly reduces the use time of the mask. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an air filter mask, which overcomes the problems of not being able to wear the mask a...
