[0002] Carbonated water is generally produced by dissolving carbon dioxide in water under pressure. Besides its use as a beverage, carbonated water can also be used for cleaning, such as for washing vegetables and bathing. The prepared carbonated water is typically stored in a storage tank. The inventors discovered during their research that some carbon dioxide is released from the carbonated water in the storage tank. Therefore, a certain concentration of carbon dioxide remains unused in the top space of the tank, resulting in waste, which needs to be addressed. Utility Model Content

[0023] One or more embodiments of this application are an improved carbonated water preparation device, the specific structure of which is as follows: Figure 1 and Figure 2 As shown. Figure 1As shown, the carbonated water preparation apparatus includes a water storage tank 10, a membrane separator 11, a compressor 12, and a mixing assembly 70. The water storage tank 10 stores the prepared carbonated water. The membrane separator 11 captures carbon dioxide gas within the water storage tank 10. The membrane separator 11 can be one of three types: a membrane separator with a polymer membrane, a membrane separator with a dense metal membrane, or a membrane separator with a porous inorganic membrane. The input end of the membrane separator 11 is connected to the top of the water storage tank 10, while the output end of the membrane separator 11 is connected to the inlet of the compressor 12. The compressor 12 is an oil-free air compressor. The mixing assembly 70 mixes the carbon dioxide gas with pressurized purified water and then delivers it to the water storage tank 10. One gas input end of the mixing assembly 70 is connected to the outlet of the compressor 12, and the output end 61 of the mixing assembly 70 is connected to the water storage tank 10. It can be seen that the carbonated water preparation device captures excess carbon dioxide in the water storage tank 10 through the membrane separator 11 and returns the carbon dioxide to the mixing component 70 for re-mixing and reuse through the compressor 12, thereby improving the carbon dioxide utilization rate and helping to reduce the preparation cost.

[0024] In some embodiments, such as Figure 1 As shown, a jacket 21 is wrapped around the outer wall of the water storage tank 10 to maintain its low temperature. Ethylene glycol refrigerant is circulated through the jacket 21. The lower the temperature of the purified water, the more carbon dioxide it can dissolve. Therefore, lowering the temperature of the water storage tank 10 by using the jacket 21 (e.g., below 5°C) reduces the release of carbon dioxide from the carbonated water, thereby reducing excess carbon dioxide in the top of the water storage tank 10 and improving carbon dioxide utilization. Specifically, as... Figure 2 As shown, the liquid outlet 211 at the top of the jacket 21 is connected to the inlet of a circulating pump 22, while the outlet of the circulating pump 22 is connected to the inlet of a plate heat exchanger 23. The outlet of the plate heat exchanger 23 is connected to the return port 212 at the bottom of the jacket 21. Therefore, ethylene glycol refrigerant circulates within the jacket 21 and the plate heat exchanger 23 under the drive of the circulating pump 22. The inlet and outlet of the plate heat exchanger 23 are connected to a refrigeration compressor 24. The plate heat exchanger 24 is used to absorb heat and cool the ethylene glycol refrigerant, keeping the ethylene glycol refrigerant in the jacket 21 at a lower temperature.

[0025] In some embodiments, such as Figure 1 As shown, the outer wall of the water storage tank 10 is also wrapped with an insulation layer 41, and the jacket 21 is sandwiched between the insulation layer 41 and the outer wall of the water storage tank 10. Specifically, the insulation layer 41 is a polyurethane insulation layer with a thickness of not less than 40 mm. The insulation layer 41 helps to maintain the cooling effect of the jacket 21 on the water storage tank 10, reduce energy consumption, and thus reduce manufacturing costs. In addition, an aluminum foil layer (not shown) for preventing water vapor from condensing is provided between the outer surface of the jacket 21 and the insulation layer 41. The aluminum foil layer covers the entire outer surface of the jacket 21. The main function of the aluminum foil layer is to prevent condensation or ice formation on the outer surface of the jacket 21, which would cause the insulation layer 41 to absorb water and thus reduce the insulation effect.

[0026] In some embodiments, such as Figure 1 As shown, the mixing assembly 70 includes a Venturi tube 30 and a nanoemulsion pump 60. The Venturi tube 30 has a gas inlet 31, a purified water inlet 32, and an outlet 33. The purified water inlet 32 ​​and the outlet 33 are on the same axis, and the gas inlet 31 is located on the side wall of the Venturi tube 30. The purified water inlet 32 ​​is used to introduce pressurized purified water, and the gas inlet 31 is used to introduce carbon dioxide. The Venturi tube 30 is used for preliminary mixing of carbon dioxide and purified water. The inlet of the nanoemulsion pump 60 is connected to the outlet 33 of the Venturi tube 30, and the outlet 61 of the nanoemulsion pump 60 is connected to the water storage tank 10 through a parallel collector 50. The nanoemulsion pump 60 uses an internal high-speed rotor to quickly and thoroughly disperse and mix the preliminarily mixed carbon dioxide and purified water, allowing the carbon dioxide to fully dissolve in the purified water. Figure 1 As shown, the gas inlet 31 is connected to at least the outlet of the compressor 12, meaning that the carbon dioxide collected from the membrane separator 11 re-enters the venturi tube 30 to mix with purified water, which helps improve carbon dioxide utilization. Specifically, as... Figure 1 As shown, the gas inlet 31 of the venturi tube 30 is connected to a three-way pipe 14, which is also connected to the outlet of the compressor 12 via a one-way valve 13, preventing gas from flowing back from the compressor 12. The remaining inlet of the three-way pipe 14 can be connected to other sources of carbon dioxide, such as a carbon dioxide storage tank.

[0027] In some embodiments, such as Figure 1 As shown, the purified water inlet 32 ​​of the Venturi tube 30 is connected to a cooler 36. The cooler 36 is used to cool the incoming pressurized purified water to achieve pre-cooling of the purified water, so that more carbon dioxide can be dissolved in the purified water in the Venturi tube 30 and the nanoemulsion pump 60, which helps to improve the carbon dioxide utilization rate. Specifically, the cooler 36 can be a plate heat exchanger.

[0028] In some embodiments, such as Figure 1 As shown, the outer wall of the pipe connecting the output port 61 of the nanoemulsification pump 60 and the water storage tank 10 is wrapped with a heat insulation layer 42, and the heat insulation layer 42 also wraps the parallel liquid collector 50, so that the carbonated water output from the nanoemulsification pump 60 does not easily heat up, maintains the carbon dioxide solubility of the carbonated water, and avoids the release of too much carbon dioxide.

[0029] The above examples are merely illustrative of the technical content of this application to facilitate reader understanding, but do not imply that the implementation methods of this application are limited to these. Any technical extensions or re-creations made based on this application are protected by this application. The scope of protection of this application is determined by the claims.
