[0025] The liquid scraping assembly includes liquid scraping plate 9, and the liquid scraping plate 9 is used to scrape the ion liquid attached to the inner wall of the cylinder sleeve 1 into the ion liquid storage cavity 7.

[0026] The top of the liquid scraping plate 9 is tightly fixed by fixing ring 10, so that the liquid scraping plate 9 is convenient to install, and the fixing ring 10 is fixedly connected with the top of the gas piston 5 by a plurality of screws.

[0027] The edge of the liquid scraping plate 9 is in sliding contact with the inner wall of the cylinder sleeve 1, so that the ion liquid attached to the inner wall of the cylinder sleeve 1 can be scraped clean.

[0028] A plurality of sealing rings 11 and guide rings 12 are arranged between the gas piston 5 on the lower side of the ion liquid storage cavity 7 and the cylinder sleeve 1, so as to play a sealing and guiding role.

[0029] Sealing rings and guide rings are arranged between the sealing shaft sleeve 16 and the piston rod 15, and a plurality of sealing rings are arranged between the sealing shaft sleeve 16 and the bottom of the cylinder sleeve 1 to seal.

[0030] The leakage detection sensor 20 includes a proximity sensor or a liquid level sensor.

[0031] Embodiment 2:

[0032] As Figure 3 shown, the difference between the present embodiment and embodiment 1 is that:

[0033] The liquid scraping assembly includes double guide ring structure 17, the double guide ring structure 17 is used to guide the reciprocating movement of the gas piston 5 and scrape the ion liquid attached to the inner wall of the cylinder sleeve 1 into the ion liquid storage cavity 7.

[0036] Working principle:

[0037] During operation, the oil piston 14 drives the gas piston 5 to reciprocate in the cylinder sleeve 1 through the piston rod 15. When the gas piston 5 moves downward, the gas enters the gas compression chamber through the gas inlet one-way valve 3. When the gas piston 5 moves upward, the gas in the gas compression chamber is compressed and pressurized, and then is discharged outward through the gas outlet one-way valve 4, thereby realizing the pressurization of the gas.

In addition, when the ionic liquid above the gas piston 5 leaks from between the gas piston 5 and the cylinder sleeve 1 to the bottom of the inner cavity of the cylinder sleeve 1, the leaked ionic liquid can enter the detection container 19 through the ionic liquid discharge channel 18, the leakage detection sensor 20 at the bottom of the detection container 19 detects the leakage signal of the ionic liquid and feeds back to the controller, the controller sends an alarm signal, and the worker can stop the machine for maintenance in time to ensure the safety of the equipment.
