The water absorption sponge 4 is laid in the inner side of the inner space 3 of the cover frame body through an inner side flat plate type net partition frame 2 which is integrated with the cover frame body and a convex edge type net partition frame 5 which is arranged at the outer side of the water absorption sponge and is provided with four circumferential net convex frame edges. The filtering cotton 7 is laid outside the convex edge type net partition frame 5 through the net support 6 and the door net cover 8 which are positioned at the inner side and the outer side of the filtering cotton. A door shaft 20 is arranged between one side (such as the left side) of the door screen cover 8 and the corresponding side (left side) of the cover frame body through the corresponding shaft hole; similarly, a self-service locking head 17 is arranged on the other side (such as the right side) of the door screen cover, a corresponding retaining ring 18 is arranged on the other side (right side) of the cover frame body, the door screen cover is connected with the cover frame body 1 through the shaft hole, the door shaft, the self-service locking head and the retaining ring, and the switch door is connected with the cover frame body. The self-help locking buckle head is an arrow-type plug buckle head, the two opposite sides of the free end of the arrow-type plug buckle head are respectively provided with inclined fins 17 a. The door guard can be unlocked and opened as easily as opening and closing the door by pressing the both-side inclined flaps 17 a. Replacing the filtering sponge and the water-absorbing sponge in the filter.

The lower part of the cover frame body 1 is provided with an isolated discharge replacement cavity 28 communicated with the inner space of the cover frame body through two one-way discharge valves, the isolated discharge device cavity 28 is provided with a discharge net partition frame 23 through a boss step 30 arranged on the inner side wall of the isolated discharge device cavity, a discharge door net cover 27 is connected with the door shaft 20, a self-service locking head 17 and a locking ring 18 through shaft holes and door shafts which are respectively arranged on the corresponding side edges of the discharge net partition frame 23 and the isolated discharge replacement cavity 28 shell and are correspondingly connected with each other, and the self-service locking head 17 and the locking ring 18 are connected with the isolated discharge replacement cavity.

The working principle and the process of the invention are as follows:

after the mask is worn, when a user inhales air, outside air enters an inner cavity (inner space) of the mask through the filter cotton, and due to the filtering effect of the filter cotton, dust, PM2.5, viruses and the like are isolated outside the mask, so that the effect that the user inhales clean air is achieved.

Assuming that the user is an infectious disease patient or a virus carrier, when the user exhales, the virus-carrying gas is firstly discharged to the isolated discharge replacement cavity through the two discharge one-way valves and then is discharged outwards through the discharge filter cotton; the discharged gas has a certain buffering and retaining effect in the isolated discharge and replacement cavity and a filtering effect of the discharge filter cotton, so that viruses are retained in the isolated discharge and replacement cavity to a certain extent, the isolation effect of the viruses is achieved, and the spread of infectious viruses can be effectively controlled.

When a user inhales, the two discharge check valves are closed, and gas enters from the air inlet filter cotton, so that the virus in the outside air or the virus in the gas exhaled by a virus carrier can be blocked inside and outside through the mask no matter the user inhales or exhales. Not only prevents the invasion of external viruses, but also blocks the outward diffusion of internal viruses, and plays a role in bidirectional protection.

The humidifying function of the heating sponge plays a certain role in relieving dryness for the human body. When the air inhaled by the user passes through the humidifying sponge, the inhaled air can be humidified, and the moisturizing effect is achieved. When the water in the sponge is used up, a proper amount of water can be added into the water-absorbing sponge from the middle of the side of the silica gel mask.

The above-described embodiments describe the technical principles of the present invention, and these descriptions are only for the purpose of explaining the principles of the present invention and are not to be construed as limiting the scope of the present invention in any way. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
