In this process, the electromagnetic valve 31 is closed, that is, the pressure of the pressure reducing valve 2 cannot be released through the exhaust nozzle 28, at this time, the pressure in the throttle chamber 27 reaches a set value to cause the constant pressure assembly to spring open, and the valve needle 41 is driven by the stop spring 42 to close the upper port of the stop valve 4, so that the gas in the gas cylinder 1 cannot be output into the throttle chamber 27.

When the pressure in the throttle chamber 27 between the piston 45 and the shut-off valve 4 increases, the piston 45 is subjected to an upward pressure, thereby overcoming the elastic potential energy of the throttle spring 46 and moving upward, thereby releasing the valve needle 41 on the shut-off valve 4. Further, the needle 41 is urged by the shutoff spring 42 to abut against a seal ring on the shutoff valve 4, so that the shutoff valve 4 is closed and the gas in the gas cylinder 1 cannot be outputted through the pressure reducing valve 2.
The mixing assembly 3 comprises a mixing container 32, the pressure reducing valve 2 is connected with the mixing container 32 through an air inlet pipeline, a pressure relief pipeline is connected to the mixing container 32, and a pressure relief valve 33 is arranged on the pressure relief pipeline; the water supply assembly comprises a water tank 34, a booster pump 35 and an atomizer 36, and the water tank 34, the booster pump 35, the atomizer 36 and the mixing container 32 are sequentially connected through a water inlet pipeline; the control panel is connected with a booster pump 35 and a pressure relief valve 33 respectively. The mixing container 32 is a switchable sealing device, firstly, gas in the gas cylinder 1 is injected into the mixing container 32 through the pressure reducing valve 2 and the gas inlet pipeline, and after the gas pressure in the mixing container 32 reaches a set value, the control panel closes the electromagnetic valve 31 to disconnect the gas inlet pipeline. Then, the booster pump 35 is started to inject the water in the water tank 34 into the mixing container 32 through the water inlet pipeline, the atomizer 36 atomizes the water to better obtain the mixing effect, and the gas content in the soda water is improved.
After the mixing is completed, the booster pump 35 is turned off and the atomizer 36 functions to close the water inlet line. The control panel opens the pressure relief valve 33 to vent the pressure in the mixing vessel 32 through the pressure relief line. In the above process, the control board can precisely control the gas filling amount in the mixing container 32, and of course, the opening time of the booster pump 35 corresponds to the water capacity in the mixing container 32, and soda water beverages with different proportions, different doses and different tastes can be obtained by precisely controlling the gas amount and the water amount, so that consumers can obtain richer taste experiences.
The mixing assembly 3 further comprises a cooling tank 37, and the mixing container 32 is immersed in the cooling tank 37, and the cooling tank 37 is filled with a cooling liquid. The cooling tank 37 changes the temperature in the mixing container 32 by the cooling liquid, thereby satisfying the taste demands of consumers. The cooling tank 37 may use an existing conventional refrigeration device, and the working principle thereof will not be described in detail. Of course, the cooling control of the cooling tank 37 may be realized by a control board.
