Problems solved by technology

The two side plates are symmetrically provided with through holes for fixing the two ends of the air leaf. After the two ends of the air leaf are inserted through the through holes, the outer end is set. Closely fixed, because the axial eccentric force will be generated in the process of turning the outer end of the air leaf at 90 degrees, the deformation and eccentricity of the air leaf itself, the two side plates, and the connection between the air leaf and the two side plates, At the same time, the overall wind wheel will be twisted, so that its concentricity and flat quality requirements cannot be guaranteed.

Abstract

The invention discloses an active air supply mask. The active air supply mask comprises a mask body. The lower portion of the mask body is provided with an air supply cavity, a respiration mask matched with the mouth and the nose is formed on the upper portion of the mask body, a direct-current fan for supplying air is arranged in the air supply cavity, an air inlet is formed in the inner side face of the air supply cavity, a filtering layer is arranged in the air supply cavity along an air inlet and an air conveying channel is formed between the air supply cavity and the respiration mask. The active air supply mask enables respiration to be smooth and is good in protection effect.

Description

technical field [0001] The invention relates to a mask, in particular to an active air supply mask. Background technique [0002] With the development of urban construction, air pollution, sandstorms, smog weather, and the prevalence of infectious diseases will cause serious harm to human health. The traditional mask is composed of a whole cover body, the outer surface of the cover body is the filter surface, and a filter material layer is set along the filter surface, and the outside air is sucked through the filter material layer through the nasal breathing force, but the breathing is caused by the resistance of the filter material layer and so on. Not smooth. At the same time, when a certain filtering effect needs to be achieved, the resistance of the filter material layer also increases proportionally, causing external air to enter from the seam between the cover body and the face, thereby affecting the filtering effect. [0003] The traditional DC motor includes a whe...
