In another specific embodiment, an elastic piece can also be arranged in the middle of the outer surface of the filter system shell. When the filter system needs to be replaced, the elastic piece can be ejected by pressing the outer surface of the filter system shell. The elastic sheet can be lifted to remove the filter system from the cover.

The filter layer of the filter system may include a coarse filter layer A, a sterilizing and antibacterial layer, a deodorizing layer, a high-efficiency filter layer and an anion layer stacked in sequence from outside to inside. The orientation words "outside" and "inside" here are designated according to the flow direction of air passing through the filter layer. Specifically, the orientation word "outside" refers to the side of the filter layer that first contacts the outside air, and the orientation word "inside" refers to the side of the filter layer that is close to the fan 61 . Coarse filter layer A and negative ion layer can be polypropylene non-woven fabric layer or activated carbon fiber, and sterilizing and antibacterial layer can be the long-staple cotton weave that uses after being soaked in chitosan solution, preferably, this long-staple cotton weave uses nanometer Woven with silver ion composite fibers; Deodorant layer includes activated charcoal and marine shell powder. The high-efficiency filter layer is a HEPA high-efficiency filter with good filtering effect, and its removal efficiency for particles with a diameter of 0.3 microns or more can reach more than 99.97%.

The filter system, power and control system are separated by a cover, and the filter system is located on the upper part of the cover, and the power and control system is located on the lower part of the cover. The periphery of the cover body is sealingly connected with the groove 34 provided on the upper surface of the visor 3 . The filtering system is detachably arranged on the upper surface of the cover body. The shape of the cover body is a crescent shape consistent with the shape of the housing of the filter system. There is a sealed connection between the cover body and the housing of the filter system. In a specific embodiment, the sealing connection structure between the cover body and the shell of the filter system can be: a circle of concave grooves are arranged at the edge of the upper surface of the cover body, and a sealing strip is arranged in the concave grooves; There is a ring of protrusions on the edge of the lower surface of the housing of the system; the protrusions on the lower surface of the housing of the filter system can be pressed into the concave grooves on the upper surface of the cover to connect the cover and the filter system, and pass through the The sealing strip in the concave groove is sealed. The utility model can prevent air that has not been purified by the filter system from entering the power and control system at the lower part of the cover by sealing the periphery of the cover with the groove 34 and combining the seal connection between the cover and the shell of the filter system. And then enter the mask 1, thereby reducing the air purification effect of the present utility model.

As shown in Figure 2, a plurality of positioning holes 36 can also be provided in the groove 34 on the upper surface of the visor 3, and a plurality of positioning posts are provided on the lower surface of the cover body, and a plurality of positioning posts and a plurality of positioning holes 36, so that a plurality of positioning posts can be correspondingly embedded in a plurality of positioning holes 36, so that the cover body is fixedly connected to the visor 3. Preferably, at least two fastening holes may be provided in the groove 34 on the upper surface of the visor 3 , and a fastening post for matching with the fastening holes is provided on the lower surface of the cover. In this way, through the cooperation of the positioning hole 36 and the positioning column, and at the same time combining the cooperation of the clamping hole and the clamping column, the cover body is more closely and firmly fixed with the visor 3 together.

In a specific embodiment of the present invention, the power and control system includes a fan 61, a battery and a circuit board.

The fan 61 is arranged at the bottom center of the groove 34 provided on the upper surface of the visor 3 . An air guide groove is provided along the outer periphery of the fan 61 to guide the air flow to the air outlet 62 . The air guide groove is formed by the upward protrusion surrounding the fan 61 and the front end wall of the cap body 2 provided on the bottom surface of the groove 34 on the upper surface of the visor 3 . Preferably, the side wall of the air guide slot is involute along the rotation direction of the fan 61 . The air outlet 62 (fresh air outlet) is arranged at the rear end of the air guide groove, close to the front wall of the cap body 2 . The air outlet 62 can be a rectangular hole. The surface of the rectangular hole close to the fan 61 is a vertical surface, and the surface close to the front end wall of the cap body 2 is an inclined surface 621 . The inclined surface 621 extends forward and downward from the lower surface of the visor 3 (ie, protrudes downward from the lower surface of the visor 3 ). The front end of the inclined surface 621 and the lower surface of the visor 3 form an angle, which is an acute angle, such as 20°-60° (such as 25°, 30°, 40°, 42°, 48°, 55° , 57°, 59°). The inclined surface 621 extends forward and downward to the lower surface of the visor 3, so that the air filtered by the filter system is first blown to the mask 1 under the action of the fan 61, and then rebounded by the mask 1 to the mouth and nose position of the user for use The user can breathe, avoiding the discomfort caused by the air blowing directly vertically downward to the user's face, especially the eyes.

An air inlet is opened at a position corresponding to the fan 61 on the cover, so that the air filtered by the filter system can pass through. Preferably, the shape of the air inlet is circular, and the circular hole is located above the fan 61 for bringing the air filtered by the filter system into the new air inlet through the rotation of the fan 61 . This ensures that the inhaled air is purified clean air.
