[0032] Embodiment 4:

[0033] This embodiment is an improvement of Embodiment 1. In this embodiment, the water inlet 710 and the liquid level detection port 713 are both fixedly provided with a stainless steel threaded sleeve 76. The quick installation connector 74 of the water inlet 710 is matchedly arranged in the threaded sleeve 76, and the liquid level detection device 75 is matchedly installed in the threaded sleeve 76.

[0034] The working principle of the soda water preparation device of the utility model is as follows: when preparing soda water, domestic water is filtered through a water purifier 14 to become direct drinking water, and the control system 9 is started. The control system 9 controls the water pump 13 to pass the filtered direct drinking water through the water inlet pipe 702 from the water inlet 710 into the water tank 7. When the water level in the water tank 7 reaches the set height, the liquid level detection device 75 is triggered, and the liquid level detection device 75 transmits a trigger signal to the control system 9. The control system 9 controls the water pump 13 to stop working, and the water intake is completed; during the water intake process, the carbon dioxide gas cylinder 1 enters the water tank 7 from the air inlet 712 through the air inlet pipe 701, and a microporous filter element 79 is installed at the end of the stainless steel air inlet pipe 78 in the water tank 7. The carbon dioxide passes through the microporous filter element 79. After that, it turns into dispersed tiny bubbles and quickly dissolves into the water. When the air pressure in the water tank 7 is the same as the air pressure in the air intake pipe 701, the air intake pipe 701 automatically stops intake. After pressing the button 10, the control system 9 controls the water outlet solenoid valve 11 to open, and the soda water in the water tank 7 is pressed out by the air pressure in the water tank 7, and water starts to flow out. After releasing the button 10 after a few seconds, the control system 9 controls the water outlet solenoid valve 11 to close, and the water flow ends. During the water flow process, the amount of water in the water tank 7 decreases, and the water level begins to drop. When the water level is lower than the height set by the liquid level detection device 75, the liquid level detection device 75 transmits a trigger signal to the control system 9, and the control system 9 controls the water pump 13 to start working, and the water level in the water tank 7 begins to rise. When the water level in the water tank 7 reaches When the height is set, the liquid level detection device 75 is triggered, and the liquid level detection device 75 transmits the trigger signal to the control system 9, and the control system 9 controls the water pump 13 to stop working; during the water discharge process, the water volume in the water tank 7 decreases, the water level begins to drop, the air pressure in the water tank 7 decreases, and the air intake pipe 701 enters the water tank 7 through the air intake pipe 78. The carbon dioxide is quickly dissolved into the newly added water by the tiny bubbles dispersed by the microporous filter element 79, so that the dissolved gas concentration of the soda water in the water tank 7 is always maintained in a fixed range; during the air intake process, the carbon dioxide enters the air intake pipe 701 from the gas cylinder 1 through the pressure regulating device 2. When the gas in the gas cylinder 1 is insufficient, the pressure in the air intake pipe 701 decreases. When the air pressure value in the air intake pipe 701 is less than When it reaches the set value, the pressure sensor 6 transmits a low-pressure signal to the control system 9, and the control system 9 controls the alarm 8 to issue a low-pressure alarm; the air intake pipeline 701 is provided with a one-way valve 3 to prevent water from flowing back into the air intake pipeline 701 when the pressure in the air intake pipeline 701 is low and the pressure in the water tank 7 is high, thereby protecting the safety of the air intake pipeline 701; when the pressure regulating device 2 works abnormally and makes the output air pressure higher than the set pressure, the air pressure in the air intake pipeline 701 increases, and when the air pressure value in the air intake pipeline 701 is greater than the set value, the pressure sensor 6 transmits a high-pressure signal to the control system 9, and the control system 9 controls the alarm 8 to issue a high-pressure alarm, and at the same time, the safety valve 5 in the air intake pipeline 701 releases pressure to protect the safety of the air intake pipeline.

[0035] The utility model water tank is a high-pressure container, which can prepare and store 10-30L of soda water at a time. During use, soda water extraction and pure water injection preparation will be carried out simultaneously. Since the speed of preparing soda water is related to the pressure and the contact area between bubbles and water, the preparation speed will be slightly slower than the extraction speed. Therefore, the continuous output of soda water is determined according to the capacity, pressure and size of the microporous filter element of the high-pressure container. The microporous valve core solves the problem of low efficiency of dissolving carbon dioxide in existing soda water, and the dissolution efficiency is increased by 40% compared with the usual soda water preparation device, and can continuously and uninterruptedly output soda water at 50ml~50L.

[0036] The method of using this device is as follows:

[0037] Step 1, start the control system 9;

[0038] Step 2, water filling the water tank 7: the water pump 13 allows the direct drinking water purified by the water purifier 14 to enter the water tank 7 from the water inlet 710 through the water inlet pipe 702;

[0039] Step 3, water tank 7 intake: during the water intake process, the high-pressure carbon dioxide gas in the carbon dioxide cylinder 1 is pressure-regulated by the pressure regulating device 2 and then enters the intake pipe 78 in the water tank 7 through the intake pipeline 701, and then filtered by the microporous filter element 79. The pore size of the microporous filter element 79 is 0.40-0.50 microns, and the working pressure is 0.2-0.5Mpa;

[0040] Step 4, mixing gas and water: the carbon dioxide gas filtered by the microporous filter element 79 becomes dispersed tiny bubbles, which are quickly dissolved with water;

[0041] Step 5, discharging soda water: after pressing the water discharging button 10, the control system 9 controls the water discharging solenoid valve 11 to open, and the soda water in the water tank 7 is pressed out by the air pressure in the water tank 7, and the water starts to be discharged. After releasing the button 10 after a few seconds, the control system 9 controls the water discharging solenoid valve 11 to close, and the water discharging ends;

[0042] Step 6, when the water level in the water tank 7 reaches the set height, the liquid level detection device 75 is triggered, and the liquid level detection device 75 transmits the trigger signal to the control system 9, and the control system 9 controls the water pump 13 to stop working, and the water intake ends; when the air pressure in the water tank 7 is the same as the air pressure in the air intake pipeline 701, the air intake of the air intake pipeline 701 automatically stops;

[0043] Step 7, during the water discharge process, the amount of water in the water tank 7 decreases, and the water level begins to drop. When the water level is lower than the height set by the liquid level detection device 75, a trigger signal is transmitted to the control system 9, and the control system 9 controls the water pump 13 to start working; during the water discharge process, the concentration of dissolved gas in the soda water in the water tank 7 is always kept in a fixed range through the control system;

[0044] Step 8, when the gas in the gas cylinder 1 is insufficient and the air pressure in the air inlet pipeline 701 is less than the set value, the alarm 8 issues a low pressure alarm;

[0045] Step 9, when the pressure regulating device 2 works abnormally and the output air pressure is higher than the set pressure, the air pressure in the intake pipe 701 increases and is greater than the set value, the pressure sensor 6 transmits the high-pressure signal to the control system 9, and the control system 9 controls the alarm 8 to issue a high-pressure alarm. At the same time, the safety valve 5 in the intake pipe 701 performs pressure relief protection.

[0046] Finally, it should be noted that the above is only used to illustrate the technical solution of the utility model and is not a limitation. Although the utility model is described in detail with reference to the preferred arrangement scheme, ordinary technicians in this field should understand that the technical solution of the utility model (such as the connection method, the shape of each element, the sequence of steps, etc.) can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
