[0021] The following is in conjunction with the appendix Figures 1-5 The specific embodiments of this utility model will be described in further detail.

[0022] This embodiment provides a pressure relief device for the handle of an inflation device, including at least one set of pressure relief devices, which includes: a side U-shaped handle 1, a handle rotating sleeve 2, a restoring torsion spring 3, a circuit board 4, a rotating pressure arm 5, a pressure arm rotating shaft 6, a valve body seat 7, a restoring spring 8, and a pressure relief rod 9.

[0023] The handle sleeve 2 is fixed to the circuit board 4 by screws through a connector. The upper horizontal arm 11 of the side U-shaped handle 1 is exposed outside the housing 50. The lower horizontal arm 12 of the side U-shaped handle 1 passes through the handle sleeve 2. The end of the lower horizontal arm 12 of the side U-shaped handle 1 is formed into a rotating arm 13. The restoring torsion spring 3 is sleeved on the rotating arm 13. The two ends of the restoring torsion spring 3 press against the rotating arm 13 and the circuit board 4 respectively, so that the side U-shaped handle 1 remains upright under the action of torque. The rotating pressure arm 5 is rotatably connected to the valve body seat 7 via the pressure arm shaft 6. The lateral protrusion 14 of the rotating arm 13 presses against the upper surface of the rotating pressure arm 5, so that when the lateral U-shaped handle 1 rotates, it can drive the rotating arm 13 to press down the rotating pressure arm 5 to rotate and press down the pressure relief rod 9. The restoring spring 8 presses against the bottom surface of the rotating pressure arm 5 and the circuit board 4. The bottom surface of the rotating pressure arm 5 presses against the top of the pressure relief rod 9. The pressure relief rod 9 is inserted into the corresponding insertion hole of the valve body seat 7.

[0024] The pressure relief device for the handle consists of two sets of handle pressure relief devices arranged symmetrically on the left and right sides.

[0025] The circuit board 4 is movably sleeved with a locking block 10, and the locking block 10 is provided with a locking knob switch 101. When the locking knob switch 101 is rotated to an unlocking position, the locking block 10 is rotated to the middle position of the rotating pressure arm 5 in the two sets of handle pressure relief devices. When the locking knob switch 101 is rotated to a locking position, the locking block 10 is rotated below the rotating pressure arm 5 in the two sets of handle pressure relief devices to prevent the rotating pressure arm 5 from being pressed downward.

[0026] In the pressure relief state, the bottom end of the pressure relief rod 9 is pressed against the cylinder nozzle 201 of the gas cylinder 20.

[0027] The valve body seat 7 is provided with a gas outlet hole 11 on the side surface.

[0028] The circuit board 4 is provided with a through slot 12 for the protruding top end of the valve body seat 7.

[0029] The valve body seat 7 is further provided with a gas cylinder plug-in rack 13 and a gas cylinder positioning rack 14.

[0030] The valve body seat 7 is further provided with a "U"-shaped gas cylinder plug-in arm 30 for abutting the cylinder nozzle 201 and a rotating positioning arm 40 for positioning the gas cylinder 20 and the valve body seat 7 after abutting.

[0031] In the specific implementation process of the handle pressure relief device of the new inflatable device, the user first installs the gas cylinder 20 on the gas cylinder plug-in rack 202 of the device and ensures that the gas cylinder nozzle 201 of the gas cylinder 20 is tightly matched with the lower opening of the valve body seat 7, so as to provide a stable gas source for subsequent gas injection. In this process, the gas cylinder positioning rack 202 helps the user to position the gas cylinder 20 and ensures that the gas cylinder 20 will not be loose or fall off. Then, the user adjusts the locking block 10 to the unlocking position by rotating the locking knob switch 101. At this time, the locking block 10 is rotated to the middle of the rotating pressure arm 5 in the two sets of handle pressure relief devices, allowing the lateral U-shaped handle 1 to rotate freely and preparing to start gas injection. Next, the user rotates the lateral U-shaped handle 1, so that the rotating arm 13 of the lower cross arm 12 drives the rotating pressure arm 5 to move downward. This action makes the rotating pressure arm 5 press downward, and the pressure relief rod 9 moves downward correspondingly, opening the cylinder nozzle 201 and starting to inject gas (such as nitrogen) into the beverage.

[0032] The lateral U-shaped handle 1 is designed to fully consider the user's operation comfort, allowing the user to easily perform multiple rotation operations to flexibly adjust the gas injection. During the gas injection process, the user can adjust the amount of injected gas according to their own needs. The structure inside the device effectively prevents excessive gas injection into the beverage, ensuring stable foam and improved beverage taste. After completing the gas injection, the handle is restored to the upright state by the restoring spring 3 and the restoring spring 8, thereby automatically closing the cylinder nozzle to prevent accidental gas leakage.

[0033] Finally, the user can rotate the locking knob 101 again after finishing using, adjust the locking block 10 to the locking position, prevent the downward pressing of the rotating pressure arm 5, ensure that the device will not be misleakage in the non-operating state, and further improve the safety. Through the above working process, the user can simply, quickly and safely complete the injection and pressure relief of the gas, and provide better taste and experience for the beverage. The design effectively improves the practicability of the gas injection equipment, solves the problems of safety hazards and operation complexity that the user may face in the use process.

[0034] Therefore, the handle pressure relief device effectively solves the problems of operation complexity and safety hazards in the prior art, and provides a more convenient, safe and efficient beverage inflation solution for users.

[0035] Of course, the utility model can also have other various implementation manners, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but these corresponding changes and deformations should all belong to the protection scope of the claims attached to the utility model.
