[0033] A one-way exhaust valve 104 and an air inlet head 105 with a removable plugging cap are connected to the surface of the mask body 1; the one-way exhaust valve 104 is a one-way exhaust mechanism that can guide the exhaust gas inside the mask body 1; after the plugging cap on the air inlet head 105 is removed, it can be connected to the oxygen supply pipe, thereby supplying oxygen to the inside of the mask body 1;

[0034] The surface of the mask body 1 is connected to the bracket 2, and the inside of the bracket 2 is connected to the breathing cavity inside the mask body 1 through a one-way air inlet valve 203. The one-way air inlet valve 203 is connected to the inner wall of the bracket 2 by multiple ribs. The one-way air inlet valve 203 is located in the middle of the bracket 2, and the one-way air inlet valve 203 is connected to the bracket 2 through a frustum-shaped outer surface. The small end surface of the frustum is arranged away from the inner space of the mask body 1. This can increase the breathing space inside the mask body 1 and improve the comfort of the device when in use.

[0035] An activated carbon filter cartridge 4 is provided inside the bracket 2. The activated carbon filter cartridge 4 is movable, that is, the activated carbon filter cartridge 4 can be removed. A mesh panel 201 is rotatably connected to the open end of the bracket 2 via a torsion spring. A sealing connector 3 detachably connected to the bracket 2 is provided at the movable portion of the mesh panel 201. After the sealing connector 3 is released from the bracket 2, the elasticity of the torsion spring at the connection between the bracket 2 and the mesh panel 201 can be used to push the mesh panel 201 to rotate away from the bracket 2, thereby realizing the opening of the bracket 2 and facilitating the removal and replacement of the activated carbon filter cartridge 4 inside the bracket 2.

[0036] In the structure of the bracket 2, the bracket 2 is a cylindrical structure, and the opening of the bracket 2 is fixedly connected to the inferior arched sheet structure, the mesh panel 201 is rotatably connected to the inferior arched structure, and the mesh panel 201 is a superior arched structure. The mesh panel 201 and the inferior arched sheet structure constitute a complete circular structure, and the formed circular structure corresponds to the opening of the bracket 2, which can seal the opening of the bracket 2, and the inferior arched sheet structure can be used to limit the activated carbon filter box 4 when installing the activated carbon filter box 4, so the use effect is better. The sealing connector 3 and the ribs inside the bracket 2 are staggered. When the bracket 2 is formed, the bracket 2, the ribs in the bracket 2, the one-way air intake valve 203 and the inferior arched sheet structure are formed by an integrated molding process;

[0037] Specifically, there are two brackets 2, which are respectively close to the left and right sides of the mask body 1. That is, when the mask body 1 is worn on the user's face, the brackets 2 correspond to the two cheeks of the user respectively, and the one-way exhaust valve 104 is located between the two brackets 2.

[0038] The second embodiment is different from the first embodiment in that:

[0039] A sealing strip 202 corresponding to the bracket 2 is provided on the inner side of the mesh panel 201. The cross-section of the sealing strip 202 is triangular or trapezoidal. When the mesh panel 201 contacts the bracket 2, the sealing strip 202 contacts the inner wall of the bracket 2. The sealing strip 202 is used to seal the gap between the bracket 2 and the mesh panel 201, and the sealing effect is better.

[0040] The third embodiment is different from the first embodiment in that:

[0041] In the structure of the sealing connector 3, the sealing connector 3 includes a fixed box 301, which is an arc-shaped box body structure, one side of which is opened and corresponds to the outer arc surface of the mesh panel 201, and a slider 304 is slidably connected to the fixed box 301.
