The framework body 200 is used as the framework of the cover body 100 and is detachably connected with the cover body 100, so that the cover body 100 can be replaced, and the cost is reduced; and, the edge of the cover body 100 is moved toward the middle by the tightening part 600, thereby increasing a sealing effect and preventing inflow of external air.
The face breathing device can be a mask, a breathing machine mask, an underwater breathing machine mask, an aerospace suit mask or a life jacket mask.
Referring to fig. 4, the ratchet 500 is used to make the ring-shaped sliding block 400 rotate only in one direction but not in reverse direction, and the ratchet 500 is provided with a switch to allow reverse rotation when the switch is turned on, which is the prior art.

The connection mode of the ratchet 500, the frame body 200 and the annular slider 400 may be: the front surface of the frame body 200 is an annular dovetail guide rail, the rear surface of the annular slider 400 is an annular dovetail groove, and the shape of the dovetail guide rail is matched with that of the dovetail groove, so that the annular slider 400 cannot be separated from the frame body 200 and can rotate along the frame body. Further, a ratchet 500 is disposed between a side surface of the inside of the dovetail groove of the ring slider 400 and a side surface of the dovetail rail, an outer ring 501 of the ratchet 500 is fixed to the side surface of the inside of the dovetail groove of the ring slider 400, and an inner ring 502 of the ratchet 500 is fixed to the side surface of the dovetail rail of the frame body 200, so that the ring slider 400 can rotate only in one direction. Moreover, when the dovetail slider needs to rotate reversely, the switch of the ratchet 500 can be opened to rotate reversely, and of course, the fork or the needle can be inserted into the ratchet 500 to toggle the connecting rod thereof to allow the reverse rotation of the ring slider 400.
To further explain the present embodiment, referring to fig. 1, 2, 3, 5, and 7, the tightening unit 600 includes a first guide rail 601, a first slide rail 602, a first locking pin 603, a first swing link 604, a first long circular hole 605, a first spring 606, and a pulling tab 607, wherein one end of the first guide rail 601 is fixed to the outer circumferential surface of the frame body 200, a first slide bar 602 moving along the first guide rail 601 is disposed in the first guide rail 601, one end of the first slide bar 602 close to the frame body 200 is fixed to the first locking pin 603, one end of the first slide bar 602 away from the frame body 200 is fixed to one end of the first spring 606, the other end of the first spring 606 is fixed to the pulling tab 607, and the pulling tab 607 is detachably fixed to the cover body 100,

According to the invention, between the first swing link 604 fixed on the annular sliding block 400 and the first guide rail 601 obliquely arranged relative to the first swing link, the first swing link 604 drives the first bayonet 603 to move through the rotation of the annular sliding block 400 relative to the framework 200, so that the first sliding rod 602 pulls the first spring 606 and pulls the pull tab 607 to move towards the center of the cover body 100, thereby enabling the stress of the edge of the cover body 100 to be more vertical to the face, and increasing the sealing property of the edge of the cover body 100.
It should be noted that, because the mask body 100 is substantially hemispherical, pulling the edge of the mask body 100 to move the center of the photographic mask body 100 tends to make the edge of the mask body 100 more perpendicular to the face to ensure sealing, which may result in better sealing by making the edge of the mask body 100 more perpendicular to the face than by making the edge of the mask body 100 parallel to the face by traditional tightening of the mask strap, because the edge of the mask body 100 is more perpendicular to the face and the face is subjected to a greater force component.
The included angle between the first swing link 604 and the first guide rail 601 may be: 15-75 degrees, preferably 45 degrees.
The first swing link 604 may be inclined in the following manner: when the ring-shaped sliding block 400 can only rotate clockwise, the first swing link 604 inclines from left to right from the direction close to the center of the cover 100 to the direction far from the center of the cover 100, so that the first detent 603 moves towards the center of the cover 100 when the first swing link rotates clockwise.
