[0026] When in use, the compression spring 406 pushes the piston plate 407 downward, squeezing the medium in the liquid storage cylinder 2 so that the medium in the liquid storage cylinder 2 has pressure and can be added to the condenser body 1. The position of the pressure plate 405 can be adjusted by rotating the adjusting screw 402 through the second connecting rod 404.

[0027] For example, Figure 4 As shown, the utility model also includes that the liquid inlet assembly 3 includes a first connecting rod 301 connected to the top of the water outlet pipe of the condenser body 1 through a pipe joint, the bottom end of the liquid storage cylinder 2 is connected to the top of the first connecting rod 301 through a threaded groove, a liquid adding pipe 304 is welded on one side of the first connecting rod 301, and the top of the liquid adding pipe 304 is connected to a liquid adding valve 305 through a threaded groove.

[0038] After the medium is added into the liquid storage cylinder 2, the piston plate 407 is pushed upward, so that the compression spring 406 is compressed, so that the medium in the liquid storage cylinder 2 has a certain pressure. After the medium in the air conditioner is consumed and lost, the pressure in the medium pipeline becomes low, and the pressurized medium in the liquid storage cylinder 2 is added into the condenser body 1 through the first connecting rod 301, and then flows into the medium pipeline;
