[0002] Carbonated beverages, also known as soda, are soft drinks made by charging water with carbon dioxide gas. In the production process, the key step is to effectively mix carbon dioxide and water to generate carbonated water. At present, there is a gas mixing machine on the market, which works by introducing carbon dioxide gas and water into a static gas-water mixing chamber. In this closed space, carbon dioxide dissolves in water and is converted into carbonic acid. Subsequently, after being treated by flow guiding and passive pressurization, the carbonated liquid is discharged for use.

[0003] However, this static mixing method has a significant defect: after carbon dioxide and water are introduced into the mixing chamber, their mixing effect is not ideal, and carbon dioxide gas is difficult to fully dissolve in the water body, resulting in that the quality of the output gas-water mixture fails to meet the expected standard, thereby affecting the taste of carbonated beverages. SUMMARY

[0027] As Figure 1 shown, the utility model embodiment provides a kind of gas mixer, comprising: jar body 1, water inlet 11 and air inlet 12 are equipped on jar body 1, water inlet end 13 and water outlet end 14 that are connected with the inside of jar body 1 are equipped on jar body 1, water pump 2 is connected between water inlet end 13 and the water outlet end 14, water pump 2 is used to extract the water in jar body 1 through water outlet end 14, and the water extracted from water outlet end 14 is sent back into jar body 1 by water inlet end 13.

[0028] Specifically, the gas mixer includes a jar body 1, which is provided with a water inlet 11 for introducing water and an air inlet 12 for introducing carbon dioxide gas. The gas mixer of the present embodiment is also specially designed with a dynamic water circulation system that communicates with the jar body 1. This system is composed of a water inlet end 13, a water outlet end 14, and a water pump 2 that connects the two ends. In operation, water enters the jar body 1 through the water inlet 11, while carbon dioxide gas enters through the air inlet 12. At this time, the water pump 2 starts to work, and it extracts the water in the jar body 1 from the water outlet end 14 and sends it back into the jar body 1 through the water inlet end 13. This process of continuous extraction and delivery actually forms a dynamic water flow in the jar body 1, which allows the incoming carbon dioxide gas to be more fully contacted and mixed. Moreover, due to the pumping action of the water pump 2, the water in the jar body 1 is constantly agitated, forming turbulent or vortex flow, which greatly increases the contact area and contact time between the water and the carbon dioxide gas, thereby further improving the solubility of carbon dioxide in water. Compared with the traditional static mixing method, this dynamic mixing method can more effectively dissolve carbon dioxide gas in water, generating higher-quality carbonated water.

[0029] In this embodiment, the water circulation system driven by the water pump 2 achieves dynamic mixing of water and carbon dioxide gas, significantly improving the mixing efficiency and allowing carbon dioxide to be more fully dissolved in water. Due to the improved mixing efficiency, the quality of the generated carbonated water is also correspondingly improved, with higher carbon dioxide content and better taste. Moreover, the dynamic mixing method in this embodiment is more adaptable to different water qualities and carbon dioxide gas pressures, and can maintain stable mixing effects under a wider range of conditions.

[0030] Optionally, as Figure 2 shown, the inside of the jar body 1 is provided with a plurality of turbulence structures 15 for disturbing the water flow in the jar body 1.

[0031] Specifically, the gas mixer is additionally provided with a plurality of turbulence structures 15 inside the tank body 1. These turbulence structures 15 can be in the form of protrusions, grooves, spiral blades, etc., which can effectively disturb the water flow and form complex flow patterns. When the water pump 2 drives the water to circulate, these turbulence structures 15 will cause the water flow to generate complex flow states such as vortex flow and turbulent flow, thereby increasing the contact area and contact time of water and carbon dioxide gas. In this way, the gas mixer of the present embodiment can significantly improve the mixing efficiency, optimize the quality of carbonated water, and enhance the durability and flexibility of the equipment. Users can choose appropriate forms and arrangements of turbulence structures 15 according to actual needs to achieve the best mixing effect and production benefit.

[0032] In this optional embodiment, the addition of turbulence structures 15 makes the water flow inside the tank body 1 more complex and variable, significantly improving the mixing efficiency of water and carbon dioxide gas, helping to generate high-quality carbonated water in a short time to meet production needs. Due to the improvement of mixing efficiency, the quality of generated carbonated water is also optimized, with more uniform and stable carbonation content and better taste, meeting the high-quality requirements of consumers for carbonated beverages. The setting of turbulence structures 15 not only improves the mixing efficiency but also helps to reduce sediment and scaling phenomena inside the tank body 1, helping to prolong the service life of the equipment and reduce maintenance costs. The diversity and customizability of turbulence structures 15 enable the gas mixer to adapt to different scales and types of carbonated beverage production needs, and users can choose appropriate forms and arrangements of turbulence structures 15 according to actual conditions to achieve the best mixing effect.

[0033] Optionally, as shown in Figure 2 The turbulence structures 15 include turbulence protrusions, which are arranged in a curved manner on the inner wall of the tank body 1 from the top to the bottom of the tank body 1. For example, a plurality of turbulence protrusions are arranged in a circumferential direction of the tank body 1.

[0034] Specifically, the gas mixer of the present embodiment is provided with a plurality of curved turbulence protrusions on the inner wall of the tank body 1. The turbulence protrusions extend in a curved manner from the top to the bottom of the tank body 1. When the water flow passes through the turbulence protrusions, it will not only be directly disturbed by the protrusions but also be forced to change the flow direction due to the curved shape of the protrusions, generating more complex vortex flow and turbulent flow. When the water pump 2 drives the water inside the tank body 1 to circulate, the water flow will flow along the inner wall of the tank body 1 and pass through the curved turbulence protrusions. Due to the curved shape of the protrusions, the water flow will be subjected to a centripetal force after contacting the protrusions, forcing it to change the original flow direction and form one or more vortexes. These vortexes will drive the surrounding water flow to rotate together, thereby increasing the contact area and contact time of water and carbon dioxide gas. At the same time, the formation of vortexes also enhances the degree of turbulent flow of the water flow, further improving the mixing efficiency.

[0035] In this optional embodiment, the curved turbulence convex strips can force the water flow to change direction, forming eddy and turbulent flow, so as to mix with the carbon dioxide gas in the water more fully, not only improving the mixing efficiency, but also making the carbon content of the carbonated water more uniform and the taste better. The setting of the turbulence convex strips helps to reduce the deposition and scaling phenomenon in the tank body 1. Since the water flow is disturbed when passing through the convex strips, it is more difficult for the deposition and scaling substances to accumulate on the inner wall of the tank body 1, thereby enhancing the stability and durability of the equipment. The curved turbulence convex strips can be designed and arranged according to actual needs to adapt to different scales and types of carbonated beverage production requirements. This flexibility enables the gas mixer of this embodiment to be widely used in various carbonated beverage production occasions.

[0036] Optionally, as shown in Figure 2 The water inlet end 13 is provided on the side wall of the tank body 1, and the water inlet pipe 131 is provided at the water inlet end 13. One end of the water inlet pipe 131 extends into the tank body 1, and the portion of the water inlet pipe 131 located in the tank body 1 is inclined relative to the radial direction of the tank body 1, so that the water flow can enter the tank body 1 in a wall-adhering manner.

[0037] Specifically, the water inlet pipe 131 does not extend into the tank body 1 along the radial direction of the tank body 1, but extends into the tank body 1 obliquely relative to the radial direction, so that the portion of the water inlet pipe 131 located in the tank body 1 is relatively close to the inner side wall of the tank body 1. When the water pump 2 starts to work, water is sucked into the tank body 1 through the water inlet pipe 131. The water flowing from the water inlet pipe 131 is close to the inner side wall of the tank body 1 and enters the tank body 1 in a wall-adhering manner. This wall-adhering entry manner enables the water to form a water flow layer along the inner wall of the tank body 1 when entering the tank body 1. The water flow layer not only increases the contact area between the water and the inner wall of the tank body 1, but also helps to guide the flow direction of the water flow in the tank body 1, so that the water flow is more uniformly distributed in the tank body 1. With the continuous work of the water pump 2, the wall-adhering water flow forms a circulating flow pattern in the tank body 1, further promoting the mixing of water and carbon dioxide gas. At the same time, since the water flow enters in a wall-adhering manner, it can also reduce the direct impact of the water flow on the carbon dioxide gas in the tank body 1, avoiding the gas from gathering to form bubbles due to impact, thereby improving the dissolution efficiency of the gas.

[0038] In this optional embodiment, the wall-adhering water flow manner enables the water to be uniformly distributed in the tank body 1, avoiding the local dead zones that may be formed by the water flow in the traditional manner, and improving the uniformity of the mixing of water and carbon dioxide gas. Since the water flow enters in a wall-adhering manner and forms a circulating flow along the inner wall of the tank body 1, it helps to more uniformly disperse the carbon dioxide gas in the tank body 1 in the water, thereby improving the dissolution efficiency of the gas. The wall-adhering water flow manner reduces the direct impact of the water flow on the gas, avoids the gas from escaping the tank body 1 due to impact, and reduces the loss of the gas.

[0039] Optionally, as shown inFigure 1 , Figure 2 As shown, the water outlet 14 is located at the bottom of the tank body 1, and a water outlet pipe 141 is provided at the water outlet 14.

[0040] Specifically, when the water pump 2 starts and drives the water in tank 1 to circulate, the water flows into tank 1 from the inlet 13 and mixes with carbon dioxide gas inside the tank. As the mixing process proceeds, the water gradually fills the entire tank 1 and flows along the inner wall and bottom of the tank, then flows into the water pump 2 through the outlet pipe 141 at the bottom outlet 14, completing one water cycle. Since the outlet 14 is located at the bottom of the tank 1, it helps to ensure that the water in the tank 1 can be fully mixed and reacted, and the water undergoes a complete circulation process within the tank 1, improving the mixing efficiency.

[0041] In this optional embodiment, bottom water outlet ensures that the water flow within tank 1 can be fully mixed and reacted, as the water undergoes a complete circulation process within tank 1. This helps reduce uneven mixing and the formation of dead zones, improving mixing efficiency. Bottom water outlet also helps enhance the stability of the equipment. Because the water flows along the inner wall and bottom of tank 1, it helps reduce the impact and vibration of the water flow on the top of tank 1, thereby extending the service life of the equipment.

[0042] Optionally, such as Figure 3 As shown, a control valve 3 is provided between the water inlet 13 and the water pump 2, and the control valve 3 is provided with an air bubble water outlet 31 that is connected to the water inlet 13;

[0043] Alternatively, a control valve 3 may be provided between the water outlet 14 and the water pump 2, and the control valve 3 may be provided with an air bubble water outlet 31 that is connected to the water outlet 14.

[0044] Specifically, when control valve 3 is positioned between the inlet end 13 and the water pump 2, its main function is to control the water flow rate entering the water pump 2, and simultaneously provide an aerated water outlet 31 connected to the inlet end 13. When the water pump 2 starts, water flows in from the inlet end 13, and after being regulated by control valve 3, flows into the water pump 2. At this time, if it is necessary to draw out the mixed aerated water, it can be achieved by opening the aerated water outlet 31 on control valve 3. When control valve 3 is positioned between the outlet end 14 and the water pump 2, its main function is to control the water flow rate flowing out of the water pump 2, and simultaneously provide an aerated water outlet 31 connected to the outlet end 14. When the water pump 2 pushes the mixed water flow to the outlet end 14, control valve 3 can regulate the outflowing water flow rate. If it is necessary to draw out the mixed aerated water, it can be achieved by opening the aerated water outlet 31 on control valve 3.

[0045] In this optional embodiment, both schemes provide an additional bubble water outlet 31, increasing the flexibility of the system. Users can choose to draw the mixed bubble water at different positions as needed without affecting the main water flow path, meeting the use needs and simplifying the water flow path.

[0046] Optionally, the control valve 3 is an electromagnetic valve.

[0047] Specifically, the electromagnetic valve is installed on the pipeline between the water inlet end 13 and the water pump 2 or between the water outlet end 14 and the water pump 2. When it is necessary to adjust the water flow or control the bubble water outlet 31, the system sends a corresponding control signal to the electromagnetic valve. The electromagnetic valve changes its opening and closing state or opening degree according to the received signal, thereby achieving precise adjustment of the water flow and precise control of the bubble water outlet 31. In addition, since the electromagnetic valve has high control precision and response speed and is easy to maintain, the gas mixer using the electromagnetic valve has higher intelligent level and operation efficiency.

[0048] In this optional embodiment, the use of an electromagnetic valve can achieve automatic control of the gas mixer, improve the intelligent level and operation efficiency of the system, and automatically adjust the opening and closing state of the electromagnetic valve through programming and sensor feedback to adapt to different working conditions and needs. The electromagnetic valve has high control precision and response speed, can achieve precise adjustment of the water flow and precise control of the bubble water outlet 31, and is helpful to optimize the performance of the gas mixer system and improve the mixing efficiency and quality of the bubble water. By precisely controlling the flow of the water flow and the opening and closing of the bubble water outlet 31, energy waste and water consumption can be reduced, and the operation cost of the system can be reduced. At the same time, the automatic control of the electromagnetic valve also helps to reduce manual intervention and misoperation, and improves the stability and reliability of the system.

[0049] Optionally, as shown in Figure 3 the air inlet 12 is arranged at the top of the tank body 1, and the water inlet 11 is arranged at the bottom of the tank body 1.

[0050] Specifically, the air inlet 12 is located at the top of the tank body 1, so that the gas can be directly injected into the high part of the tank body 1. The layout helps the gas to be uniformly distributed in the tank body 1 and gradually dissolved with the flow or stirring of the water in the tank body 1. The water inlet 11 is arranged at the bottom of the tank body 1, which means that the water enters from the bottom of the tank body 1, ensuring that the water can enter the tank body 1 smoothly, reducing the turbulence and bubbles caused by the impact of the water body, and the bottom water inlet helps the liquid to form an upward flow in the tank body 1, promoting the full contact and mixing of the gas and water. When the gas enters from the top and the liquid enters from the bottom, a natural convection circulation is formed in the tank body 1, and the gas gradually dissolves in the water during the upward process to form bubble water.

[0051] In this optional embodiment, the layout of the gas inlet 12 and the water inlet 11 helps to form an effective convection circulation of gas and water in the tank 1, thereby improving the mixing efficiency. The gas can be more evenly distributed in the water, forming more tiny bubbles, increasing the surface area and time of gas dissolution.

[0052] Optionally, as shown in Figure 3 The tank 1 includes a tank cover 16 and a tank body 17. The tank body 17 is provided with an open end, and the tank cover 16 is adapted to the tank body 17 to close the open end of the tank body 17. A detachable sealing connection structure is provided between the tank cover 16 and the tank body 17 to achieve sealing connection.

[0053] Specifically, the tank body 17 is the main part for containing the medium, and the top of the tank body 17 is provided with an open end. The shape and size of the tank cover 16 are adapted to the open end of the tank body 17 to ensure that the tank cover 16 can tightly cover the open end of the tank body 17. In order to realize the tight connection between the tank cover 16 and the tank body 17, a detachable sealing connection structure is provided between the tank cover 16 and the tank body 17 in this embodiment. This structure can adopt various ways such as threaded connection, buckle connection, flange connection, etc. to ensure the firm connection and sealing performance between the tank cover 16 and the tank body 17. During the connection process, sealing materials (such as rubber gaskets, O-rings, etc.) are also used to further enhance the sealing effect. When the tank cover 16 and the tank body 17 are tightly connected through the sealing connection structure, they form a closed cavity between them, which helps to maintain the purity and stability of the medium in the tank 1 and prevent the medium from leaking or external impurities from entering. At the same time, since the sealing connection structure is detachable, the tank cover 16 can be easily detached for cleaning and maintenance operations.

[0054] In this optional embodiment, the tank cover 16 and the tank body 17 are independent components that can be manufactured and processed separately, enhancing the flexibility of the tank 1 structure and allowing the tank 1 to be customized and optimized according to different application requirements. By adopting a detachable sealing connection structure, the tank cover 16 and the tank body 17 can form a tight sealing connection, effectively preventing the medium from leaking, which is particularly important for applications that require maintaining the purity and stability of the medium. Since the sealing connection structure is detachable, the tank cover 16 can be easily detached to clean and maintain the inside of the tank 1, which helps to prolong the service life of the tank 1 and maintain its performance.

[0055] Optionally, as shown in Figure 4 The water level sensor 18 is connected to the tank cover 16.

[0056] Specifically, the water level sensor 18 is directly connected or installed on the tank cover 16, ensuring that the water level sensor 18 can accurately sense the liquid level in the tank 1. The water level sensor 18 has sufficient sensitivity and accuracy to reflect the water level changes in the tank 1 in real time.

[0057] In this optional embodiment, by connecting the water level sensor 18, real-time monitoring of the liquid level in the tank 1 can be realized, ensuring that the operator can timely understand the water level condition in the tank 1.

[0058] Although the utility model discloses as above, the protection scope of the utility model is not limited to this only.The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will all fall into the protection scope of the utility model.
