[0036] 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 often used for direct drinking or mixing drinks.

[0037] 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, the purified water or filtered water is purified to remove impurities and odors; then, high-purity carbon dioxide is injected into a high-pressure sealed container, and the pressure is used 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, the carbonated water is sealed in bottles or cans through high-pressure filling technology 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 home-made sparkling water can inject carbon dioxide through equipment, the carbon dioxide concentration, bubble fineness, and storage time are usually inferior to industrial products.

[0038] Refer to Figures 1 to 3In order to increase the concentration of carbon dioxide in homemade sparkling water, the present invention proposes a carbonizer, including a main body 1, which is square and has a turbulent flow channel 2 arranged along its circumference. The arrangement of the square main body 1 makes it easy to process and is conducive to the overall modular design, thereby facilitating the integration and modular design of home appliances using the carbonizer, and further facilitating the miniaturization development trend of home appliances; in addition, a number of turbulent flow columns 21 and a plurality of pairs of turbulent flow protrusions 22 are arranged in the turbulent flow channel 2 along its extension direction, the turbulent flow columns 21 and the turbulent flow protrusions 22 are arranged alternately, and the turbulent flow columns 21 and the turbulent flow protrusions 22 are used to generate turbulence, which further increases the gas-liquid contact area, thereby increasing the rate at which carbon dioxide dissolves in water.

[0039] Specifically, in the present invention, the cross section of the spoiler column 21 in the length direction is rhombus-shaped, that is, the spoiler column 21 is a quadrangular prism with a rhombus-shaped cross section; when the gas-liquid mixture flows in the spoiler flow channel 2, the spoiler column 21 can cut the fluid at multiple angles to form uniform turbulence and avoid local mixing blind spots; the shape design of the spoiler column 21 can cut the fluid more effectively than a cylindrical shape, reduce flow resistance, and induce vortex generation to enhance the mixing effect; it should be noted that, when observing from the cross section of the spoiler column 21, one end of the cross section is directly opposite to the gas-liquid mixture. Flow direction of the mixture; the diamond-shaped cross-section of the spoiler column 21 ensures uniform diversion of the gas-liquid flow, avoids flow deviation caused by excessive resistance on one side, and the end point is directly opposite to the flow direction to reduce the fluid impact resistance, so that the fluid can be smoothly separated along both sides to form a stable and symmetrical vortex, further improving the diversion uniformity and turbulence intensity, and optimizing the gas-liquid mixing efficiency; in addition, the spoiler column 21 is arranged on the central axis of the spoiler channel 2, thereby ensuring symmetrical diversion of the fluid, so that the gas-liquid mixture can be evenly distributed to the flow channels on both sides, avoiding insufficient local mixing due to biased flow.

[0040] Reference Figures 1 to 3 In the present invention, a pair of spoiler protrusions 22 is two spoiler protrusions 22, and the two spoiler protrusions 22 are respectively arranged on the opposite side walls of the spoiler flow channel 2, and the two spoiler protrusions 22 are symmetrically arranged along the central axis of the spoiler flow channel 2; after the fluid is diverted by the spoiler column 21, the symmetrically arranged spoiler protrusions 22 guide the fluid on both sides to converge toward the central axis, forming a "diversion-aggregation" circulation flow pattern, forcing the fluid to collide and shear, and further aggravating the degree of turbulence; from another perspective, the spoiler protrusions 22 increase the roughness of the inner wall of the spoiler flow channel 2, thereby destroying the fluid boundary layer, promoting a more complete mixing of gas microbubbles and liquid, and improving 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 the arc-shaped or flat protrusions, it can more effectively break the large bubbles in the gas-liquid mixture, form smaller-sized bubbles, thereby increasing the gas-liquid contact surface area; and further improving the solubility of carbon dioxide in water. It should be noted that in the present invention, the cross-section of the spoiler protrusion 22 being triangular in its length direction can ensure the symmetric diversion of the fluid and the symmetry of the turbulence formed in the fluid, further improving the gas-liquid mixing efficiency.

[0042] Regarding the spoiler columns 21 and the spoiler protrusions 22, the spoiler columns 21 are themselves arranged on the central axis of the spoiler flow channel 2, and their cross-sections are diamond-shaped, that is, a symmetry axis of the cross-section of the spoiler columns 21 coincides with the central axis of the spoiler flow 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 flow channel 2; the above symmetric arrangement enables the fluid to be symmetrically diverted, 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 full gas-liquid contact within the entire cross-section of the flow channel, and further increasing the concentration of carbon dioxide in the bubble water.

[0043] Refer to Figures 2 to 4 As shown in the figure, 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 spoiler flow channel 2. Thus, the gas-liquid mixture will enter the impeller groove 3 after passing through the spoiler 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 increasing 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.

[0044] 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 when the fluid flows 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.

[0045] Refer to Figures 2 to 4, 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 the number of blades 311 and mating ribs 33 in the present invention is equal; when the impeller 31 rotates, the blades 311 rotate at high speed to generate centrifugal force, which throws 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, forms additional eddy currents, and superimposes with the shear generated by the blades 311 during rotation, further improving the uniformity of gas-liquid mixing.

[0046] Specifically, in the process of gas-liquid mixing by 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 can play a key role when the impeller 31 rotates at high speed; when the gas-liquid mixture is thrown 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 hitting the mating ribs 33. This high pressure not only further breaks the bubbles to promote 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 with 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 possible concentration stratification phenomenon, 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.

[0047] Refer to Figure 5 , and before the gas-liquid mixture enters the turbulent 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 turbulent 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;

[0048] 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 of a cone shape. The expansion section 413 is located between the throat section 412 and the outlet section 44 and is also arranged in a frustum of a cone shape. It should be noted that the contraction section 411, the throat section 412, and the expansion section 413 all refer to the walls of the area 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 the hollow tubular structures connected to the main body 1, which have inner walls and outer walls 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.

[0049] 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 at 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, and improve 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-increasing - pressure-decreasing - pressure-increasing 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 primary gas-liquid mixing efficiency.

[0050] 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. That is, the carbonator further includes a connecting pipe 11 and a gas pipe 12. The connecting pipe 11 is used to introduce the liquid into the turbulent flow channel 2, and the gas pipe 12 is used to introduce the gas into the turbulent flow channel 2. The gas and liquid are directly mixed in the turbulent flow channel 2, canceling the preliminary mixing link of the Venturi; removing the setting of the Venturi tube 4 simplifies the overall structure, reduces the number of components, lowers 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, makes the structure of the carbonator more compact, and is 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.

[0051] Referring to Figure 1 and Figure 6 In addition, the carbonator proposed by the present invention further includes a cover plate 5, and the cover plate 5 is used to seal the main body 1 of the carbonator; it should be noted that in order to simplify the manufacturing difficulty of the carbonator, the above-mentioned turbulent flow channel 2 adopts an open manufacturing method to avoid using processing methods with high difficulty and high cost such as internal molding, thereby reducing the manufacturing difficulty and cost of the carbonator; specifically, the turbulent flow channel 2 is opened on one side of the carbonator main body 1, and the cover plate 5 is hermetically fixed to the side of the main body 1 where the turbulent flow channel 2 and the impeller groove 3 are opened to seal the main body 1 and prevent fluid from overflowing.

[0052] Correspondingly, a mating portion 51 protrudes from the side of the cover plate 5 facing the main body 1. The mating portion 51 cooperates with the impeller groove 3, and a limiting portion 312 protrudes from the end of the impeller 31. The mating portion 51 and the impeller groove 3 are closely matched, enhancing the stability of the entire structure, ensuring the accurate flow path of the gas-liquid mixture in the carbonator, making the impeller 31 more stable during rotation, reducing shaking and offset, and thus improving the efficiency and effect of gas-liquid mixing. The limiting portion 312 is located at the end of the impeller 31, which increases the distance between the blade 311 and the cover plate 5, effectively preventing the blade 311 from rubbing against the cover plate 5 when the impeller 31 rotates at high speed, reducing the noise and wear caused by friction, and extending the service life of the impeller 31. The two cooperate. The mating portion 51 provides a basis for the stable rotation of the impeller 31 from the overall structural stability; the limiting portion 312 focuses on reducing the frictional loss between the impeller 31 and the cover plate 5, ensuring the continuous and efficient operation of the impeller 31, and jointly ensuring the stable and efficient operation of the carbonator and improving the preparation quality of the bubble water.

[0053] Referring to Figure 1 and Figure 6In 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.

[0054] Reference Figure 1 and Figure 6 In the present invention, a sealing gasket 53 is further provided between the cover plate 5 and the main body 1. The provision of the sealing gasket 53 significantly increases the sealing pressure range of the cover plate 5, so that the carbonizer as a whole can withstand higher pressure without leakage, thereby further increasing the solubility of carbon dioxide in water; in combination with the above, an avoidance groove is provided on the sealing gasket 53, and the avoidance groove is used to avoid the matching portion 51. The setting of the avoidance groove reserves space for the rotation of the impeller 31 to avoid the jamming caused by the interference of the sealing gasket 53 with the movement of the impeller 31. At the same time, the cooperation between the avoidance groove and the matching portion 51 maintains the high air tightness of the impeller groove 3; and in order to further improve the sealing effect of the sealing gasket 53, a sealing groove 13 is formed in a depression on one side of the main body 1, and a sealing protrusion 14 is provided in the sealing groove 13. The sealing protrusion 14 conflicts with the sealing gasket 53 to provide sealing. The sealing protrusion 14 conflicts with the sealing gasket 53 to form a labyrinth sealing structure, which further reduces the possibility of fluid leakage and can well cope with the sealing failure problem during vibration or pressure fluctuation, especially suitable for frequent start-stop scenarios in a home environment.

[0055] The present invention also proposes a bubble water machine, which includes the above-mentioned carbonizer. The specific structure of the carbonizer refers to the above-mentioned embodiment. Since the bubble water machine adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.
