Anti-haze face mask

Abstract

The invention discloses an anti-haze face mask. The mask comprises a face mask body, a filter screen and a turbofan are arranged in the face mask body, and the face mask body is provided with a first mask shell, a second mask shell and flexible sheets; intake holes are formed in the first mask shell, an isolation base is mounted in the face mask body, the filter screen is mounted between the isolation base and the first mask shell, the turbofan is mounted between the isolation base and the second mask shell, air flows from the intake hole to the filter screen, and an air-intake duct is formed; an air guiding wall is arranged on the outer periphery of the turbofan, an inlet and an outlet are formed in the air guiding wall, the air in the air-intake duct is blown by the turbofan from the inlet to the outlet, and a wind shifting duct is formed; the outlet of the air guiding wall corresponds to the bottoms of the flexible sheets, the air blown out from the wind shifting duct is divided into two parts and enters two sides of the flexible sheets respectively, and a circulating outtake duct is formed. Therefore, the air is drawn in by the turbofan automatically, filtered fresh air enters the internal respiratory cavity in a tender mode, and the comfort of breathing is improved.

Description

Technical field [0001] The present invention relates to the field of mask technology, in particular to an anti-haze mask. Background technique [0002] Masks are commonly used products in people’s daily lives. They have a series of basic functions such as dustproof, warmth, and hygiene. The basic components are composed of the main body of the mask and the straps. The main function is to isolate the human mouth, nasal cavity and the outside world. Contact to achieve the role of purification and health care. [0003] The main applications of mainstream masks on the market are dustproof, warmth and health care. In order to more effectively prevent dust, PM2.5 and some common pollutants in the atmosphere, some masks have an activated carbon layer inside. , In order to achieve a better filtering effect. A common disadvantage of masks with activated carbon layer is that the mask has a high sealing property, which causes the user to not breathe smoothly, especially during long-distance...
