[0035] Sparkling water is a type of drinking water that produces bubbles by dissolving carbon dioxide gas. Its core feature is the presence of carbon dioxide. It can be classified into two categories according to its source: natural sparkling water (such as some natural mineral waters that contain carbon dioxide due to geological activities) and artificial sparkling water (made by injecting carbon dioxide into purified water). The essential difference between it and soda water lies in the composition - soda water needs to add baking soda, may contain sodium and is weakly alkaline, while sparkling water only relies on carbon dioxide to form bubbles, has a refreshing taste, and is commonly used for direct drinking or mixing drinks.

[0036] Generally speaking, natural sparkling water is relatively scarce, so the price of natural sparkling water is relatively high. Therefore, there are more artificial sparkling waters on the market. The production of artificial sparkling water is based on the industrial process of forcing carbon dioxide to dissolve in water: First, purify the purified water or filtered water to remove impurities and odors. Then, inject high-purity carbon dioxide into a high-pressure sealed container, and use pressure to force the gas to dissolve to form carbonic acid and produce bubbles. Some products will add mineral salts or fruit flavor extracts to adjust the taste. Finally, use high-pressure filling technology to seal the carbonated water in bottles or cans to ensure the bubbles are persistent and stable. The core difference between it and natural sparkling water lies in the gas source (artificially injected / naturally formed). Although homemade sparkling water can inject carbon dioxide through equipment, the carbon dioxide concentration, bubble fineness, and shelf life are usually inferior to industrial products.

[0037] Refer to Figures 1 to 3, in order to increase the carbon dioxide concentration in the home-made sparkling water, the present invention proposes a carbonator, which includes a main body 1. The main body 1 is circular, and a turbulent flow channel 2 is arranged along its circumference inside the main body 1. The circular shape of the main body 1 and the shape distribution of the turbulent flow channel 2 enable the gas-liquid mixture to flow along an annular path, thereby prolonging the contact time between the gas and the liquid, which is conducive to the dissolution of carbon dioxide in water. In addition, a number of turbulent flow columns 21 and a number of turbulent flow protrusions 22 are arranged along the extension direction of the turbulent flow channel 2. The number of turbulent flow columns 21 and the number of pairs of turbulent flow protrusions 22 are arranged alternately. The turbulent flow columns 21 and the turbulent flow protrusions 22 are used to generate turbulence, further increasing the gas-liquid contact area, and thus increasing the rate of carbon dioxide dissolution in water.

[0038] It should be noted that the circular carbonator main body 1 and the turbulent flow channel 2 arranged along its circumference inside it have no sharp corners. When the gas-liquid mixture flows along the circumferential turbulent flow channel 2, the fluid resistance is evenly distributed, avoiding the generation of flow dead zones. Moreover, the hydraulic radius of the circular channel is the largest, the friction resistance coefficient is relatively low, and the energy loss during the fluid flow process is small. In addition, the stress distribution of the circular main body 1 is symmetric under high-pressure environments, and the wall thickness can be thinned while still maintaining strength, thereby reducing the material cost during the production of the carbonator.

[0039] Specifically, in the present invention, the cross-section of the turbulent flow column 21 in its length direction is diamond-shaped, that is, the turbulent flow column 21 is a quadrangular prism with a diamond-shaped cross-section. When the gas-liquid mixture flows in the turbulent flow channel 2, the turbulent flow column 21 can cut the fluid at multiple angles, forming uniform turbulence and avoiding local mixing blind spots. The shape design of the turbulent flow column 21 can cut the fluid more effectively compared to cylindrical shapes and other shapes, reducing the flow resistance and inducing the generation of eddy currents to strengthen the mixing effect. It should be noted that when observing from the cross-section of the turbulent flow column 21, one end point of the cross-section is facing the flow direction of the gas-liquid mixture. The diamond-shaped cross-section of the turbulent flow column 21 ensures uniform diversion of the gas-liquid flow, avoiding flow deviation caused by excessive unilateral resistance, and the end point facing the flow direction can reduce the fluid impact resistance, enabling the fluid to smoothly separate along both sides, forming stable and symmetric eddy currents, further improving the diversion uniformity and turbulence intensity, and optimizing the gas-liquid mixing efficiency. In addition, the turbulent flow column 21 is arranged on the central axis of the turbulent flow channel 2, ensuring symmetric diversion of the fluid, enabling the gas-liquid mixture to be evenly distributed to the two side channels, and avoiding insufficient local mixing caused by uneven flow.

[0040] Refer to Figures 1 to 3, in the present invention, a pair of spoiler protrusions 22 means two spoiler protrusions 22, and the two spoiler protrusions 22 are respectively arranged on opposite side walls of the spoiler channel 2, and the two spoiler protrusions 22 are symmetrically arranged along the central axis of the spoiler channel 2; the symmetrically arranged spoiler protrusions 22 guide the fluids on both sides to converge towards the central axis after the fluid is split by the spoiler columns 21, forming a "split-convergence" cyclic flow pattern, forcing the fluids to collide and shear, further intensifying the degree of turbulence; from another perspective, the spoiler protrusions 22 increase the roughness of the inner wall of the spoiler channel 2, thereby destroying the fluid boundary layer, promoting the more sufficient mixing of gas microbubbles and liquid, and enhancing the carbonization efficiency.

[0041] Specifically, the cross-section of the spoiler protrusion 22 in its length direction is triangular, so that the angular edges of the spoiler protrusion 22 can cut and guide the fluid. Compared with arc-shaped or flat protrusions, it can more effectively break large bubbles in the gas-liquid mixture, form smaller-sized bubbles, thereby increasing the gas-liquid contact surface area; further increasing the solubility of carbon dioxide in water. It should be noted that in the present invention, the triangular cross-section of the spoiler protrusion 22 in its length direction can ensure the symmetric splitting of the fluid and the symmetry of the turbulence formed in the fluid, further improving the gas-liquid mixing efficiency.

[0042] Regarding the combination of the spoiler columns 21 and the spoiler protrusions 22, the spoiler columns 21 are themselves arranged on the central axis of the spoiler channel 2, and their cross-sections are rhombic, that is, a symmetry axis of the cross-section of the spoiler columns 21 coincides with the central axis of the spoiler channel 2, and the spoiler protrusions 22 belonging to the same pair are also symmetrically arranged with respect to the central axis of the spoiler channel 2; the above symmetric arrangement enables the fluid to be symmetrically split, and the spoiler columns 21 cooperate with the spoiler protrusions 22 on both sides to enable the fluid to form symmetric convergent eddies, enhancing the stability and uniformity of the turbulence, ensuring the full contact of gas and liquid within the entire cross-section of the flow channel, and further increasing the concentration of carbon dioxide in the bubble water.

[0043] However, it should be noted that in the above description, since the main body 1 is circular and the spoiler channel 2 is arranged along the circumferential direction of the main body 1, that is, the spoiler channel 2 is arc-shaped, the symmetry described above refers to approximate symmetry, not perfect symmetry.

[0044] Refer to Figures 2 to 4, Further, an impeller groove 3 is also provided in the main body 1. An impeller 31 is concentrically arranged in the impeller groove 3, and the impeller groove 3 communicates with the end of the turbulent flow channel 2. Thus, the gas-liquid mixture will enter the impeller groove 3 after passing through the turbulent flow channel 2, and the impeller 31 will rotate under the impact of the fluid; when the impeller 31 rotates, the impeller 31 can further break the large bubbles existing in the fluid through centrifugal force and shear force, further improving the dissolution rate of carbon dioxide in water. At the same time, the pressure gradient generated by the rotation of the impeller 31 promotes the dissolution of carbon dioxide under high pressure, further increasing the solubility of carbon dioxide in water.

[0045] It should be noted that the impeller groove 3 is also circular, and the impeller groove 3 is coaxially arranged with the main body 1, that is, the main body 1, the impeller groove 3 and the impeller 31 are coaxially arranged. Thus, when the impeller 31 rotates, the centrifugal force is balanced and its vibration noise is small.

[0046] An arc segment 23 is provided at the end of the turbulent flow channel 2. The arc segment 23 is used to introduce the gas-liquid mixture from the turbulent flow channel 2 into the impeller groove 3; in the present invention, at least one turbulent flow column 21 is provided in the arc segment 23; the setting of the arc segment 23 can guide the gas-liquid mixture to smoothly transition from the turbulent flow channel 2 to the impeller groove 3, avoiding flow separation and pressure mutation caused by a right-angle turn, so as to ensure that the fluid entering the impeller 31 is uniform and stable, reducing the possibility of the dissolved carbon dioxide in the water precipitating out of the water again; and the turbulent flow column 21 in the arc segment 23 continues the flow splitting effect, maintaining the intensity of the turbulence at the curvature change of the flow channel, preventing the attenuation of the turbulence caused by the change of the flow channel, and ensuring that a high-intensity mixing state is still maintained at the inlet of the impeller 31 cavity, thereby further reducing the possibility of the dissolved carbon dioxide in the water precipitating out of the water again.

[0047] Refer to Figures 2 to 4 , In order to support the impeller 31, an impeller 31 shaft is provided in the impeller groove 3, and the impeller 31 shaft is coaxially arranged with the impeller groove 3; the coaxial arrangement of the impeller 31 shaft and the impeller groove 3 ensures the rotation accuracy of the impeller 31 and reduces the radial runout of the impeller 31; the stable rotation of the impeller 31 can stably convert the fluid kinetic energy into shear force and pressure energy, reducing the energy loss of the fluid after flowing through the impeller 31, thereby reducing the pressure loss of the fluid when flowing out. At the same time, the pressure gradient is evenly distributed, improving the pressure consistency of the mixed fluid at the outlet of the impeller 31 cavity.

[0048] Specifically, the impeller 31 includes a number of blades 311. A number of mating ribs 33 are formed by protrusions on the side walls of the impeller groove 3. It should be noted that in the present invention, the number of blades 311 and mating ribs 33 is equal. When the impeller 31 rotates, the blades 311 rotate at high speed to generate centrifugal force, which flings the gas-liquid mixture towards the groove wall. The mating ribs 33 block the fluid to form an instantaneous high pressure. The bubbles are broken and dissolved during the impact, thereby further increasing the solubility of carbon dioxide in water and further increasing the concentration of carbon dioxide in the final product. Further, the arrangement of the mating ribs 33 disrupts the boundary layer flow, forming additional eddy currents, which are superimposed on the shear generated by the blades 311 during rotation, further improving the uniformity of gas-liquid mixing.

[0049] Referring to Figures 2 to 4 , specifically, in the process of gas-liquid mixing in a traditional static mixer, due to the lack of effective secondary flow disturbance means, it is difficult to achieve sufficient and uniform mixing of gas and liquid in the axial direction, resulting in an axial concentration gradient problem. This means that at different positions in the axial direction of the mixer, the degree of gas-liquid mixing is different, making the dissolution concentration of carbon dioxide in water uneven and affecting the quality stability of the bubble water. In the present invention, the mating ribs 33 provided on the wall of the impeller groove 3 play a key role when the impeller 31 rotates at high speed. When the gas-liquid mixture is flung towards the groove wall by the blades 311, the mating ribs 33 block the fluid, causing the fluid to generate an instantaneous high pressure at the moment of impacting the mating ribs 33. This high pressure not only further breaks the bubbles and promotes dissolution but also disrupts the stable laminar boundary layer that might otherwise form. The presence of the mating ribs 33 causes the fluid to generate additional eddy currents in local areas. These eddy currents are superimposed on the main shear flow generated by the rotation of the impeller 31 to form a complex turbulent state. In this turbulent state, the gas and liquid are continuously stirred and mixed in the axial direction, thereby breaking the concentration stratification phenomenon that might otherwise occur, making the distribution of carbon dioxide in water more uniform, effectively solving the axial concentration gradient problem of the traditional static mixer, improving the uniformity and stability of the carbon dioxide concentration in the bubble water, and ensuring that the bubble water flowing out of the carbonator is more consistent in quality.

[0050] Referring to Figure 5 , before the gas-liquid mixture enters the turbulence flow channel 2 for mixing, there will be a preliminary mixing process. To ensure the stability of the gas-liquid mixture when it enters the turbulence flow channel 2, the present invention provides a Venturi tube 4 to perform preliminary mixing on the gas and liquid and then introduce it into the carbonator. Specifically, the Venturi tube 4 has a main body 1 part, as well as an inlet section 42, a suction section 43, and an outlet section 44 connected to the main body 1 part. The main body 1 part is provided with a contraction section 411, a throat section 412, and a diffusion section 413. The inlet section 42 is connected to the contraction section 411, and both ends of the diffusion section 413 are respectively connected to the throat section 412 and the outlet section 44.

[0051] The main body 1 is also provided with an air cavity 45. The suction section 43 is communicated with the throat section 412 through the air cavity 45. The contraction section 411 is located between the inlet section 42 and the throat section 412 and is arranged in a frustum shape. The expansion section 413 is located between the throat section 412 and the outlet section 44 and is also arranged in a frustum shape. It should be noted that the contraction section 411, the throat section 412, and the expansion section 413 all refer to the wall surfaces of the areas formed within the main body 1 through which water or carbon dioxide can flow. The inlet section 42, the suction section 43, and the outlet section 44 refer to hollow tubular structures connected to the main body 1, which have inner wall surfaces and outer wall surfaces, and correspondingly have inner diameters and outer diameters. The air cavity 45 is arranged around the outer periphery of the contraction section 411. The air cavity 45 is generally arranged in an annular cavity, which can be a regular annular cavity or an irregular cavity, and no specific limitation is made in this regard.

[0052] Referring to Figure 5 , one end of the inlet section 42 is connected to the large end of the contraction section 411. The small end of the contraction section 411 is correspondingly arranged opposite to one end of the throat section 412. The other end of the throat section 412 is connected to the small end of the expansion section 413. The large end of the expansion section 413 is connected to the outlet section 44. The suction section 43 is communicated with the throat section 412 through the air cavity 45. The air cavity 45 is formed in the main body 1 and is located on the outer periphery of the contraction section 411 and on one side of the throat section 412 at the same time. This structural design enables the water flow to gradually increase in velocity and decrease in pressure when passing through the inlet section 42 and entering the contraction section 411, forming a negative pressure in the throat section 412, sucking in carbon dioxide through the air cavity 45, and mixing it with the high-speed water flow. The reasonable design of the contraction section 411, the throat section 412, and the expansion section 413, as well as the surrounding arrangement of the air cavity 45, ensure the sufficiency and stability of the gas-liquid mixing, improving the preparation efficiency and quality of the bubble water. The contraction section 411 - throat section 412 - expansion section 413 structure of the main body 1 forms a multi-stage velocity increase - pressure decrease - pressure increase flow field, enabling the liquid velocity to be significantly increased in the throat section 412, thereby increasing the gas-liquid contact area and further improving the initial gas-liquid mixing efficiency.

[0053] In the present invention, the application of the Venturi tube 4 can also be cancelled, and the gas and liquid are directly introduced into the head end of the turbulent flow channel 2 through two pipelines, and the gas and liquid are directly mixed in the turbulent flow channel 2, canceling the initial mixing link of the Venturi; removing the setting of the Venturi tube 4 simplifies the overall structure, reduces the number of components, reduces the manufacturing complexity and cost, makes the carbonator easier to produce and assemble, also reduces potential failure points, and improves the equipment reliability; in terms of space utilization, removing the setting of the Venturi tube 4 saves the space occupied by the Venturi tube 4, making the carbonator structure more compact and more suitable for installation in equipment with limited space; in addition, in terms of the mixing effect, the gas and liquid directly enter the turbulent flow channel 2, can enter the high-intensity mixing stage faster, and reduce the energy loss caused by the pre-mixing of the Venturi tube 4.

[0054] Reference Figure 6 In addition, the carbonizer proposed in the present invention also includes a cover plate 5, which is used to seal the main body 1 of the carbonizer; it should be noted that in order to simplify the manufacturing difficulty of the carbonizer, the above-mentioned spoiler channel 2 adopts an open manufacturing method to avoid the use of internal molding and other processing methods that are difficult and costly, thereby reducing the manufacturing difficulty and cost of the carbonizer; specifically, the spoiler channel 2 is opened on one side of the carbonizer main body 1, and the cover plate 5 is sealed and fixed to the side of the main body 1 where the spoiler channel 2 and the impeller groove 3 are opened, so as to seal the main body 1 and prevent fluid overflow.

[0055] Correspondingly, a limiting protrusion 51 cooperating with the impeller 31 is provided on the cover plate 5, and the limiting protrusion 51 is used to limit the impeller 31, and the limiting protrusion 51 is provided with a matching groove 511 for the impeller 31 shaft to be embedded; the setting of the limiting protrusion 51 limits the axial displacement of the impeller 31, avoiding friction between the impeller 31 and the bottom surface of the impeller groove 3 or the cover plate 5, thereby avoiding noise and wear that may be caused by friction, and further extending the service life of the impeller 31.

[0056] Reference Figure 6 In order to fix the cover plate 5, a plurality of corresponding screw holes 52 can be opened on the main body 1 and the cover plate 5, and then the cover plate 5 can be fixed to the main body 1 by bolts. This fixing method can provide a stable and reliable connection, ensuring that when the carbonizer works under high pressure, the cover plate 5 fits tightly with the main body 1, effectively preventing gas and liquid leakage, ensuring the stable carbonization process, and avoiding carbon dioxide loss and reduced mixing efficiency caused by leakage. In addition, the bolt connection is easy to disassemble and install, which is convenient for the later inspection, maintenance and replacement of the impeller 31, spoiler column 21 and other components inside the carbonizer, reducing the difficulty of maintenance and extending the service life of the equipment. The design of multiple screw holes 52 corresponding to each other makes the cover plate 5 evenly stressed, avoiding deformation caused by uneven local stress, maintaining the structural integrity of the carbonizer, and then ensuring the shape accuracy of the gas-liquid spoiler flow channel 2, ensuring that the gas and liquid flow in the flow channel according to the designed path, stably exerting its spoiler and mixing effects, and improving the preparation quality of bubble water.

[0057] Reference Figure 6, in the present invention, a gasket 53 is further provided between the cover plate 5 and the main body 1. The provision of the gasket 53 significantly increases the sealable pressure range of the cover plate 5, so that the whole carbonator can withstand higher pressures and is not prone to leakage, thereby further increasing the solubility of carbon dioxide in water. Combining the above, the gasket 53 is provided with an avoidance groove for avoiding the impeller 31. The provision of the avoidance groove reserves space for the rotation of the impeller 31, avoiding jamming caused by the interference of the gasket 53 with the movement of the impeller 31, and at the same time maintaining the high airtightness of the impeller groove 3. In order to further improve the sealing effect of the gasket 53, a sealing groove 11 is formed by recessing one side of the main body 1, and a sealing protrusion 12 is provided in the sealing groove 11. The sealing protrusion 12 abuts against the gasket 53 to provide sealing. The sealing protrusion 12 and the gasket 53 abut to form a labyrinth sealing structure, further reducing the possibility of fluid leakage, and can well cope with the problem of sealing failure during vibration or pressure fluctuation, especially suitable for the frequent start-stop scenario in a household environment.
