Abstract

The invention discloses a novel air filtering mask which comprises a mask body. The left end and the right end in the mask body are each provided with an air exchange cavity with an upward opening, and an air filtering mechanism for filtering air is arranged in each air exchange cavity. The mask has an automatic wearing function, and the mask can be automatically worn on the heads of various sizesby installing an elastic wearing belt and matching the elastic wearing belt with a telescopic respirator, so that the mask wearing efficiency is greatly improved, and the application range is greatlywidened; and the structure of automatically filtering air and intermittently updating the air in the mask is adopted, the purity of air inhaled by a wearer can be effectively guaranteed, the utilization rate of the air in the mask is increased, when the air is filtered, the mask can automatically sense the working state of a filter plate through the wind power of the inhaled air and automaticallyreplace the filter plate which loses the filtering function so that the air filtering function of the mask can be continuously maintained, and a wearer can continuously use the mask for a long time.

Description

technical field [0001] The invention relates to the field of filtration, in particular to a novel 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 a novel air filter mask, which overcomes the problems of not being able to autom...
