Abstract

The invention provides an active type multipurpose protection mask which comprises a mask body. The body is a shell with the outer side being convex and the inner side being an inwards-concave cavity. A closed contact ring for covering the face of a person is arranged on the side of the inwards-concave cavity of the mask body in a secondary-primary clamping buckle embedded mode. A cover with the two sides being convex in an arc-shaped mode covers the convex outer side of the mask body in the same secondary-primary clamping buckle embedded mode. According to the active type multipurpose protection mask, active ventilation design is adopted, and thus mask breathing resistance is lowered; air holes are formed in the two sides of the mask body, heat exchange between the mask body and the exhaled air can be conducted, the inhaled air temperature is increased, and direct excitation of the cold air is lowered.

Description

technical field [0001] The invention relates to the field of protective masks, in particular to an active multipurpose protective mask. Background technique [0002] At present, the number of smog days in cities is increasing, and the concentration of PM2.5 pollutants in the air remains high. Indoors, air purifiers have been widely used for filtering, and the demand for purifying products worn by people is gradually increasing. Existing personal smog protection is mainly realized through N95 grade masks, etc. There are several problems in the existing masks: due to the high filtration level of the existing masks, the corresponding air resistance is large, thereby increasing the breathing resistance, and the breathing is not smooth enough. Especially for those with weak respiratory function, such as the elderly, children and those with respiratory diseases, wearing a mask may cause breathing difficulties; poor fit to the face, unfiltered air can be inhaled; poor aesthetics. ...
