An air inlet pipe 3 is connected to the lower part of the outer surface of the gas storage tank 2. A mounting bracket 4 is fixedly connected to the rear part of the top of the base 1, and a control box 5 is fixedly connected to the front part of the mounting bracket 4. An installation pipe 6 connects the top of the base 1 and the bottom of the control box 5. A compression mechanism 7 is installed inside the control box 5. Control mechanisms 8 are installed inside the control box 5, both above and below the compression mechanism 7. An air outlet pipe 9 is connected to the top of the outer surface of the gas storage tank 2. A mounting pipe 3 is fixed to one side of the top of the base 1. An air compressor 10 is fixedly connected to the air compressor 10. The air outlet of the air compressor 10 is connected to a vent pipe 19. One end of the vent pipe 19 is connected to one end of the air inlet pipe 3. The air compressor 10 and the nitrogen generator 20 are electrically connected to an external power source. Both are controlled to be turned off by the first button 82 and started by the first button 16. The nitrogen generator 20 is fixedly connected to one side of the base 1. The nitrogen generator 20 and the air compressor 10 are connected by a fixed pipe 21. An electromagnetic valve 11 is provided on the outer surface of the air outlet pipe 9. The electromagnetic valve 11 is electrically connected to an external power source. It is controlled to be turned off by the second button 83 and started by the second button 17.

[0020] Furthermore, in order to automatically press and trigger the control mechanism 8, the squeezing mechanism 7 includes a squeezing cylinder 71, which is fixedly connected to one side of the inner cavity of the control box 5. A squeezing rod 72 is slidably connected inside the squeezing cylinder 71. A squeezing plate 74 is fixedly connected to one end of the squeezing rod 72. A spring 73 is sleeved between the outer surface of the squeezing cylinder 71 and the outer surface of the squeezing rod 72. A sealing gasket 18 is fixedly installed on the outer surface of the squeezing plate 74.

[0021] Furthermore, in order to facilitate the control of the air intake pipe 3 and the air outlet pipe 9, the control mechanism 8 includes a fixing rod 81, which is fixedly connected to one side of the inner cavity of the control box 5. A first button 82 and a second button 83 are respectively fixedly installed at one end of the two fixing rods 81. A first button 16 adapted to the first button 82 is fixedly installed on one side of the front of the control box 5, and a second button 17 adapted to the second button 83 is fixedly installed on the other side of the front of the control box 5.

[0022] A groove 12 is provided on one side of the base 1, and an air tank 13 is provided inside the groove 12.

[0023] By loosening several bolts, the gas tank 13 can be easily disassembled and replaced.

[0024] In use, nitrogen is generated by nitrogen generator 20. The air intake pipe 3 on air compressor 10 draws the generated nitrogen into storage tank 2, increasing the amount of nitrogen in storage tank 2. When storage tank 2 is full, the pressure of nitrogen in storage tank 2 increases, causing nitrogen in storage tank 2 to enter control box 5. Due to the increased nitrogen pressure in control box 5, the nitrogen pressure squeezes extrusion plate 74, pushing extrusion plate 74 to move. When storage tank 2 and control box 5 are full of nitrogen, extrusion plate 74 will move and contact the first button 82 and the second button 83. The first button 82 will control air compressor 10 and nitrogen generator 20 to shut down, and the second button 83 will control solenoid valve 11 to open. Due to the pressure, nitrogen in storage tank 2 is introduced into storage tank 13 through outlet pipe 9 and connecting pipe 14.

[0025] After nitrogen from storage tank 2 is introduced into storage tank 13, multiple bolts are removed to remove storage tank 13 and replace it with a new one. Then, pressing the first button 16 controls the air compressor 10 and nitrogen generator 20 to continue producing nitrogen. At the same time, pressing the second button 17 controls the solenoid valve 11 to close. Simultaneously, the force of spring 73 causes the extrusion rod 72 and extrusion cylinder 71 to push the extrusion plate 74 to reset. Nitrogen is then introduced into storage tank 2 through the air inlet pipe 3.
