when the key structure 410 is pressed, the key structure 410 drives the connector 420 to translate integrally, the buckle 421 and the clamping groove 311 are tripped, the door plate 310 is opened, and the oxygen battery 500 is taken out from the shell 100; when the oxygen battery 500 is assembled into the breathing circuit module, the door panel 310 is closed, and the buckle 421 is engaged with the clamping groove 311.

In the present embodiment, the housing 100 as a whole exhibits a rectangular parallelepiped-like appearance shape. The housing 100 includes a bottom surface of a rectangular parallelepiped and four side walls formed by extending four sides of the bottom surface in a substantially vertical direction, and any two adjacent side walls among the four side walls are connected to each other, and the connection portion is transited by a rounded corner. The oxygen cell holder 200 is assembled at a position adjacent to one of the short sides of the housing 100, one end of the oxygen cell holder 200 is provided with an opening toward the door panel 310, so that the oxygen cell 500 is exposed when the door panel 310 is opened, the oxygen cell 500 takes a cylindrical-like external shape, and when the oxygen cell holder 200 is assembled into the breathing circuit module, the axial line of the oxygen cell 500 is substantially perpendicular to the short side of the housing 100.

In the existing door cover opening and closing mechanism, a door cover provided with a lock catch, a lock seat clamped with the lock catch and an unlocking button are of three mutually independent structures, wherein the door cover is required to be rotatably connected with a shell through parts such as a rotating shaft and a bearing so as to be opened and closed, and the lock seat is also required to be rotatably connected with the shell through the parts such as the rotating shaft and the bearing so as to be clamped with the lock catch and released. In the housing provided in this embodiment, the door panel 310 and the connecting piece 420 are not required to be mounted on the housing through the rotating shaft and the bearing, so that the components are reduced, the structure is simplified, and the assembly is more convenient and efficient.

In addition, in the existing door cover switch mechanism, the clamping connection between the lock catch and the lock seat is released by pushing the lock seat to rotate through the unlocking button, and the problem that the lock seat is difficult to reset or is inaccurate to reset, so that the lock seat cannot be contacted and pushed to rotate for unlocking by pressing the unlocking button exists. In the housing provided in this embodiment, the buckle 421 is disposed at one end of the connecting piece 420, and the connecting piece 420 and the button structure 410 are integrally formed, and when the button structure 410 is pressed, the connecting piece 420 and the buckle 421 are driven to translate synchronously, so that the mechanical transmission between the button structure 410 and the connecting piece 420 as well as between the buckle 421 is omitted, the components are further reduced, the structure is simplified, the mechanical design is optimized, the failure rate is reduced, and the use is more convenient.

When the key structure 410 is mounted into the switch fixing case 430, the top of the key 412 is slightly exposed from the top of the mounting groove 434, and the spring is in an original state, and does not act, and in the process of applying pressure to the key structure 410 to press the key structure into the inner side of the casing 100, the spring is pressed, and at this time, the spring slowly stores force, and when the pressure applied to the key structure 410 disappears, the spring is released, and the key is bounced back to the initial position.

The side wall of the mounting groove 434 is provided with a limiting hole 435 along the moving direction of the key structure 410, specifically, the limiting hole 435 is substantially rectangular, and the back-off 411 can slide back and forth towards the extending direction of the long side of the limiting hole 435. When the key structure 410 is installed into the switch fixing shell 430, the back-off 411 enters the limit hole 435, at this time, the back-off 411 abuts against the side wall of the limit hole 435 near the short side of the opening 110, and in the process of pressing the key structure 410 into the inner side of the casing 100 by applying pressure, the back-off 411 moves towards the inner side of the casing 100 along the limit hole 435, and can move until the back-off 411 abuts against the side wall of the limit hole 435 near the short side of the opening 110, so as to limit the moving distance of the back-off 411 by the length of the long side of the limit hole 435. When the pressure applied to the key structure 410 disappears, the key structure 410 rebounds towards the outer side of the casing 100, the back button 411 moves towards the outer side of the casing 100 along the limiting hole 435, and after a certain distance of movement, the key structure 410 does not move any more under the limitation of the limiting hole 435, so that the key structure 410 is restored to the initial position.
