The pressure relief valve upper cover 130 is threadedly connected to the threaded head 114 of the pressure relief valve 110 and exposed outside the pressure relief valve mounting hole 21.

[0024] A gasket 140 is further disposed below the pressure relief valve upper cover 130 .

[0025] The pressure relief valve 110 includes: a valve body 111, a valve core 112, a spring 113, a threaded head 114 and a fastening nut 115. The valve core 112 is movably inserted in the valve body 111, the threaded head 114 is threadedly connected to the upper end of the cavity of the valve body 111, and the fastening nut 115 is threadedly connected to the threaded head 114 to position the threaded head 114 on the valve body. The spring 113 is sleeved on the valve core 112 and pressed between the valve core 112 and the threaded head 114 so that the bottom end surface of the valve core 112 is elastically sealed on the air inlet hole 111a of the valve body 111.

[0026] An air outlet 111b is provided on the side wall of the valve body 111. When the pressure relief valve 110 is in a pressure relief state, high-pressure gas is discharged through the air inlet 111a, the inner cavity of the valve body 111, the air outlet 111b, the pressure relief valve mounting hole 21 and the pressure relief hole 131 of the pressure relief valve upper cover 130.

[0027] The connection end 81 of the liquid outlet nozzle 80 is sleeved with a faucet quick-release mechanism 90, which includes: a retaining ring 91, a pull ring 92, a spring 93, a steel ball 94, and a water outlet nozzle 95. The upper opening on the water outlet nozzle 95 is adapted to the connection end 81 of the liquid outlet nozzle 80, and the lower opening of the pull ring 92 is adapted to the water outlet nozzle 95. A card slot 953 for the retaining ring 91 to be inserted is provided at the upper end of the outer side of the water outlet nozzle 95. Steel ball holes 951 for accommodating steel balls 94 are provided at intervals on the side wall of the water outlet nozzle 95. The upper end of the inner wall of the pull ring 92 is formed into a thin wall 921 and a thick wall 922. There is also an inner cavity 96 for accommodating the reset spring 93 between the pull ring 92 and the water outlet nozzle 95. When in the plug-in state, the upper opening of the water outlet nozzle 95 is sleeved It is arranged on the connecting end 81 of the liquid outlet nozzle 80, and the pull ring 92 is inserted into the water outlet nozzle 95. The outer side of the retaining ring 91 presses against the intersection of the thin wall 921 and the thick wall 922 of the pull ring to stop. The steel ball 94 protrudes from the steel ball hole 951 under the pressure of the thick wall 922 of the pull ring 92 and is stuck in the groove 82 corresponding to the connecting end 81 of the liquid outlet nozzle 80. The reset spring 93 presses between the water outlet nozzle 95 and the pull ring 92 and makes the pull ring 92 have the elastic force to reset upward; when in the disassembled state, the pull ring 92 compresses the reset spring 93 under the action of external force and moves downward, the outer side of the steel ball 94 presses against the thin wall 921 of the pull ring 92, and the inner end of the steel ball 94 withdraws from the groove 82 corresponding to the connecting end 81 of the liquid outlet nozzle 80.

[0028] The water outlet 95 has a downward water outlet 952 .

[0029] The inner opening diameter of the steel ball hole 951 is smaller than the diameter of the steel ball 94 to prevent the steel ball 94 from slipping out of the steel ball hole 951 .

[0030] The inner cavity 96 between the pull ring 92 and the water outlet 95 is formed by a staggered combination of an inverted L-shaped cross-sectional groove on the inner wall of the pull ring 92 and an L-shaped cross-sectional groove on the outer wall of the water outlet 95 .

[0031] The retaining ring 91 is an annular ring with a notch, and the retaining ring 91 is embedded in the slot 953 of the water outlet 95 .

[0032] When the faucet quick-release mechanism 90 is disassembled, the pull ring 92 is pulled outward by hand, and the pull ring 92 compresses the return spring 93 under the action of external force and moves outward, and the outer side of the steel ball 94 presses against the thin wall 921 of the pull ring 92, and the inner end of the steel ball 94 withdraws from the groove 82 corresponding to the connecting end 81 of the liquid outlet nozzle 80, thereby disassembling the faucet quick-release mechanism 90 for cleaning;

[0033] When installing the faucet quick-release mechanism 90, first pull the pull ring 92 outward by hand to insert the water outlet 95 into the connecting end 81 of the liquid outlet 80. After releasing the hand, the pull ring 92 is reset under the action of the reset spring 93, and the steel ball 94 protrudes from the steel ball hole 951 under the pressure of the thick wall 922 of the pull ring 92 and is stuck in the groove 82 corresponding to the connecting end 81 of the liquid outlet 80 to complete the installation.

[0034] When the pressure relief device is relieving pressure, when the pressure of the high-pressure gas in the bottle body 10 exceeds the set pressure value, the high-pressure gas enters from the air inlet 111a of the pressure relief valve 110, overcomes the elastic force of the spring 113, pushes open the bottom end surface of the valve core 112, enters the inner cavity of the valve body 111, and is then discharged from the air outlet 111b on the side wall of the valve body 111, and is discharged to the outside through the pressure relief valve installation hole 21 and the pressure relief hole 131 of the pressure relief valve upper cover 130, thereby preventing the high-pressure gas from splashing out.

[0035] It can be seen that the utility model has the characteristics of quick disassembly and assembly, easy cleaning and maintenance, and pressure relief protection function.

[0036] Of course, the present invention may have many other implementation modes. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the utility model, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the utility model.
