To ensure the safe use of the micro-pressure oxygen chamber, in case of emergency, it is necessary to relieve the pressure of the micro-pressure oxygen chamber. Pressure relief valves are provided both outside and inside the micro-pressure oxygen chamber, and the double pressure relief method can relieve the pressure of the micro-pressure oxygen chamber more safely and efficiently.

[0003] The existing external pressure relief valve of the micro-pressure oxygen chamber is usually directly exposed to the outside. When the micro-pressure oxygen chamber is in use, if the external pressure relief valve is accidentally touched, the pressure of the micro-pressure oxygen chamber will be relieved, thus reducing the experience of the internal users. Moreover, the pressure relief may not be in a safe state, having potential safety hazards. Therefore, a device that avoids accidental touching of the external pressure relief valve is needed to prevent the external pressure relief valve from being accidentally touched.

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following will further describe the implementation manners of the present utility model in detail with reference to the attached drawings.

[0028] Please refer to Figures 1-3 As shown, this embodiment is a double micro-pressure oxygen chamber manual rapid pressure relief device, including:

[0029] An oxygen chamber component, the oxygen chamber component includes an oxygen chamber shell 11;

[0030] An anti-misoperation component, the anti-misoperation component includes a telescopic spring 21, a baffle 22, a movable column 23, a clamping block 24, a protection plate 25, a through hole 26 and a card slot 27. The telescopic spring 21 is fixedly connected to the outer end position of the oxygen chamber shell 11, the baffle 22 is fixedly connected to the outer end position of the telescopic spring 21, the movable column 23 is fixedly connected to the inner position of the baffle 22, the clamping blocks 24 are fixedly connected to both outer sides of the movable column 23, the protection plate 25 is slidably connected to the inner position of the outer side of the oxygen chamber shell 11, the through hole 26 is opened at the inner position of one end of the protection plate 25, and the card slot 27 is opened at the outer position of one end of the protection plate 25;

[0031] The telescopic spring 21 is used to reset the baffle 22. The baffle 22 is used to support the movable column 23. The block 24 is used to limit the movable column 23. The protection plate 25 is used to block the outside of the external pressure relief valve 12. The through hole 26 is used to allow the block 24 to pass through the inside of the protection plate 25. The card slot 27 is used to limit the block 24.

[0032] The oxygen chamber assembly further includes an external pressure relief valve 12 and an internal pressure relief valve 13. The external pressure relief valve 12 is fixedly connected to one end of the outside of the oxygen chamber housing 11. The internal pressure relief valve 13 is fixedly connected to one end of the inside of the oxygen chamber housing 11.

[0033] The external pressure relief valve 12 is used to relieve the pressure of the oxygen chamber housing 11 from the outside. The internal pressure relief valve 13 is used to relieve the pressure of the oxygen chamber housing 11 from the inside.

[0034] The through hole 26 and the card slot 27 are opened relative to the block 24, and the through hole 26 and the card slot 27 are staggered with each other.

[0035] When the positions of the block 24 and the through hole 26 correspond, the block 24 can move outwards from the inside of the through hole 26. When the positions of the card slot 27 and the block 24 correspond, the card slot 27 blocks the block 24.

[0036] The protection plate 25 is located outside the external pressure relief valve 12, and the movable column 23 passes through the protection plate 25 and extends to both sides.

[0037] When the movable column 23 is located inside one end of the protection plate 25, the movable column 23 can fix the protection plate 25 outside the external pressure relief valve 12.

[0038] Working principle: When it is necessary to block the outside of the external pressure relief valve 12, move the protection plate 25 to the outside of the external pressure relief valve 12 and rotate the movable column 23, so that the movable column 23 drives the block 24 to rotate. When the positions of the block 24 and the through hole 26 correspond, apply an outward force to the movable column 23, so that the movable column 23 drives the block 24 and the baffle 22 to move outwards. The outward movement of the baffle 22 drives the telescopic spring 21 to stretch. When the block 24 moves out of the inside of the protection plate 25, rotate the movable column 23 again, so that the movable column 23 drives the block 24 to rotate. When the block 24 rotates to correspond to the position of the card slot 27, stop applying the force to the movable column 23. Under the elastic force of the telescopic spring 21, the baffle 22 moves inwards, so that the baffle 22 drives the block 24 to move into the card slot 27 through the movable column 23, thereby limiting the movable column 23 by the block 24. The limitation of the movable column 23 blocks the protection plate 25, so that the protection plate 25 is fixed outside the external pressure relief valve 12, and the external pressure relief valve 12 can be prevented from being accidentally touched. When it is necessary to use the external pressure relief valve 12 to relieve the pressure, just operate the above steps in reverse.

[0039] Please refer toFigure 4 As shown in the figure, on the basis of the above-mentioned embodiment, this embodiment further includes:

[0040] A crushing assembly, which includes a fixing plate 31, a movable rod 32, a support frame 33 and a crushing needle 34. The fixing plate 31 is fixedly connected to the outer side of the oxygen chamber shell 11. The movable rod 32 penetrates through the fixing plate 31 and extends to both sides. The support frame 33 is fixedly connected to one end of the movable rod 32. The crushing needle 34 is fixedly connected to the outer side of the support frame 33;

[0041] The fixing plate 31 is used to support the movable rod 32. The movable rod 32 is used to drive the support frame 33 to move outwards. The support frame 33 is used to support the crushing needle 34. The crushing needle 34 crushes the protective plate 25.

[0042] The support frame 33 is of a U-shaped structure, and the crushing needles 34 are located at both outer sides of the protective plate 25;

[0043] Since the support frame 33 is located on both sides of the protective plate 25, the movement of the support frame 33 will not contact the external pressure relief valve 12.

[0044] Working principle: When an emergency occurs and it is necessary to use the external pressure relief valve 12 for pressure relief, an outward force is applied to the movable rod 32, so that the movable rod 32 drives the support frame 33 to move outwards. The outward movement of the support frame 33 drives the crushing needle 34 to move outwards, so that the crushing needle 34 crushes the protective plate 25 from the inside. The broken protective plate 25 does not block the external pressure relief valve 12, so that the external pressure relief valve 12 can be used.
