Abstract

The invention discloses an efficient filtration type anti-haze mask. The mask comprises a mask body (1). A head belt (2), a filter box (5) and an expiration valve piece (9) are installed on the mask body (1). A filter layer (11) is placed inside the filter box (5). A filter box cover (3) is installed on the outer side of the filter box (5). A filter cover cap (8) is installed on the inner side of the filter box (5). The filter cover cap (8) is provided with the expiration valve piece (6) through a rivet (9). A layer of efficient filter paper (4) is arranged on the inner side face of the filter layer (11) inside the filter box (5), and a layer of charcoal cloth (10) is arranged on the outer side face of the filter layer (11). The inner side face of the filter box (5) is in an arc shape matched with the bottom of the mask body (1) in appearance. The edge of the mask body (1) is of an arc turnup hem structure. The mask is exquisite in structure and high in filtering performance, promotes filter paper replacement and achieves efficient filtering of haze on the basis of being portable.

Description

Technical field [0001] The invention relates to the field of personal protective filter appliances, in particular to a high-efficiency filter type anti-smog mask. Background technique [0002] The masks of the anti-smog masks on the market are generally assembled from soft rubber materials and plastic materials, which require high assembly, and it is difficult to ensure the air tightness after assembly; in addition, similar anti-smog masks on the market generally use non-woven fabrics Filtering smog, the filtering effect is difficult to reach 99.95%; the filter box and mask on the market are not closely matched after assembly, which makes the shape of the mask not compact. Summary of the invention [0003] The purpose of the present invention is to provide a high-efficiency filter mask for haze represented by PM2.5. The mask has a novel molding method, greatly improves the filtering performance and is convenient to replace, the mask has a compact appearance and a novel structure. ...
