[0023] When working, the center of the first connecting rod 1101 is hinged with the inner wall of the compressor 1001 through the hinge seat, so that the first connecting rod 1101 can swing inside the compressor 1001.

[0024] In one specific embodiment of the present invention, a through sliding groove 1105 is provided on the side of the two first connecting rods 1101 that are far apart from each other.

[0026] In one specific embodiment of the present invention, a third link 1103 is provided between the bottoms of the two second links 1102.

[0027] In one specific embodiment of the present invention, the shock absorption device 120 includes a second sliding rod 1203, a top piston 1010 having a sliding cavity 1206, the second sliding rod 1203 being slidably connected to the sliding cavity 1206, a first limiting boss 1204 being fixedly provided at the bottom of the second sliding rod 1203, a spring 1207 being provided at the bottom of the first limiting boss 1204, a second limiting boss 1205 being provided at the top of the sliding cavity 1206, a fixing seat 1202 being fixedly provided at the top of the second sliding rod 1203, and a rubber pad 1201 being fixedly provided at the top of the fixing seat 1202.

[0028] During operation, the second sliding rod 1203 is slidably connected to the sliding cavity 1206, allowing the second sliding rod 1203 to slide within the sliding cavity 1206. The spring 1207 is designed to cushion the impact on the rubber pad 1201.

[0029] The specific workflow is as follows: High-purity hydrogen and high-purity oxygen are supplied to the combustion chamber 1016 through the second inlet 1004. The second inlet check valve 1013 opens, and the second exhaust check valve 1014 closes. Then, the gas to be compressed is supplied to the inner cavity of the compressor 1001 through the first inlet 1002. At this time, the first inlet check valve 1011 opens, and the first exhaust check valve 1012 closes, ensuring that the amount of gas to be compressed is greater than the amount of gas in the combustion chamber 1016. This results in the pressure of the gas to be compressed being greater than that of the gas in the combustion chamber 1016. The piston 1010 moves towards the combustion chamber 1016. During this movement, the piston 1010 contacts the first connecting rod 1101, causing the piston 1010 to drive the first connecting rod 1101 to swing downwards. Due to the first sliding... Rod 1106 is slidably connected to sliding groove 1105, while second connecting rod 1102 is slidably connected to inner wall of compressor 1001. This causes first connecting rod 1101 to swing downward, driving second connecting rod 1102 to move upward. The two second connecting rods 1102 drive third connecting rod 1103 and pressure block 1104 to move upward, thereby causing pressure block 1104 to squeeze the pressing head of piezoelectric igniter 1015. This causes piezoelectric igniter 1015 to generate an electric spark to ignite hydrogen. The high-purity hydrogen will explode when ignited. The impact force of the explosion will push piston 1010 to move towards the side where gas needs to be compressed, compressing the gas. At this time, first intake check valve 1011 is closed, first exhaust check valve 1012 is opened, and the compressed gas is discharged from first intake port 1002. When the piston 1010 moves toward the side of the gas to be compressed, the rubber pad 1201 will first contact the top inner wall of the compressor 1001 and compress the spring 1207 through the second sliding rod 1203. The spring 1207 will absorb the impact generated by the hydrogen explosion and prevent excessive impact damage to the equipment.
