[0043] The sales volume of high-end sparkling water in the current market has also been increasing year by year, and the acceptance of users for sparkling water has been continuously improving. At the same time, the requirements for the taste concentration and the overall volume of the sparkling water are also getting higher and higher. However, the automatic sparkling water machines currently on the market generally cannot meet the pursuit of users for the quality of sparkling water, mainly because the technical solutions of the commonly used high-pressure carbonation tanks on the market result in insufficient concentration of the produced sparkling water.

[0044] In view of this, the present invention proposes an over-current carbonator 100.

[0045] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the over-current carbonator 100 includes a main body portion 1 and an impeller 2. An installation groove 11 is formed in the middle of the main body portion 1, and a turbulence channel 12 is formed outside the installation groove 11. The turbulence channel 12 includes a starting section and an ending section. An inlet pipe 13 and an inlet gas pipe 14 are arranged on the outer side of the main body portion 1. The inlet pipe 13 and the inlet gas pipe 14 are respectively communicated with the starting section, and the ending section is communicated with the installation groove 11; the impeller 2 is rotatably arranged in the installation groove 11; wherein, a plurality of pairs of turbulence portions 3 are protrudingly arranged along the extending direction of the turbulence channel 12, the turbulence portions 3 are connected to the side wall of the turbulence channel 12, and the turbulence portions 3 are used for generating turbulence to increase the gas-liquid contact area.

[0046] It should be noted that the turbulence channel 12 refers to a channel for guiding the flow of the gas-liquid mixture, which can be specifically realized by an annular or wavy flow channel. In this embodiment, it is realized by connecting two linear flow channels, and the fluid shear force is generated by changing the flow direction. The turbulence portion 3 refers to a protruding structure periodically distributed along the wall surface of the flow channel, which can be specifically realized by a triangular or trapezoidal cross-section, and local eddies are generated by blocking the fluid. The installation groove 11 refers to a cavity structure for accommodating the rotating impeller 2, which can be specifically realized by a cylindrical cavity and forms a clearance fit with the outer diameter of the impeller 2. The starting section and the ending section refer to the inlet and outlet regions of the turbulence channel 12, which can be specifically realized by a gradually expanding or gradually shrinking flow channel. The starting section is used for receiving the gas-liquid input, and the ending section is used for flowing the mixture into the impeller 2 region.

[0047] Specifically, the liquid and the gas respectively enter the starting section of the turbulence channel 12 through the inlet pipe 13 and the inlet gas pipe 14, and a gas-liquid mixture is formed in the flow channel. During the flow of the mixture along the turbulence channel 12, a plurality of pairs of turbulence portions 3 continuously change the flow direction of the fluid, generating high-frequency turbulence to continuously break and recombine the gas-liquid interface. After the mixture processed by the turbulence enters the installation groove 11, the rotating impeller 2 further cuts the fluid into tiny bubbles, and the rib plate 111 forms a secondary turbulence barrier on the groove wall. During the whole process, the turbulence structure and the dynamic impeller 2 form a two-stage mixing mechanism, and the gas-liquid contact area increases exponentially.

[0048] Compared with the prior art, traditional high-pressure carbonization tanks rely solely on container pressure to promote gas dissolution, and the mixing process lacks an active perturbation mechanism. This solution achieves efficient gas-liquid mixing in a limited space by constructing a multi-stage turbulent flow system, and can achieve the same dissolution effect without relying on a high-pressure environment. The collaborative design of the flow channel structure and the impeller 2 significantly reduces the equipment volume while ensuring the mixing efficiency.

[0049] Through the above technical solution, this application effectively solves the technical problem of insufficient bubble water concentration. The turbulence generated by the turbulence part 3 significantly increases the gas-liquid contact area, and the shear force formed by the rotation of the impeller 2 further refines the bubble size. The dual effects improve the carbon dioxide dissolution rate. The compact layout of the flow channel and the impeller 2 realizes the miniaturization of the equipment while ensuring the mixing efficiency, meeting the space requirements of modern kitchen appliances.

[0050] In one embodiment, please refer to Figure 2 and Figure 4 , a plurality of turbulence columns 4 are arranged along the extending direction of the turbulence channel 12, the plurality of turbulence parts 3 and the plurality of turbulence columns 4 are arranged alternately, and the turbulence columns 4 are arranged on the bottom wall of the turbulence channel 12.

[0051] This application further proposes an overcurrent carbonizer 100, which includes a main body part 1, an impeller 2 and a turbulence channel 12. A plurality of turbulence columns 4 are arranged along the extending direction of the turbulence channel 12, the plurality of turbulence parts 3 and the plurality of turbulence columns 4 are arranged alternately, and the turbulence columns 4 are arranged on the bottom wall of the turbulence channel 12.

[0052] Among them, the turbulence column 4 refers to a columnar structure distributed on the bottom wall along the length direction of the turbulence channel 12, and can be specifically realized by adopting a cylindrical or prismatic structure, and its height does not exceed half of the depth of the turbulence channel 12. The alternate arrangement of the turbulence part 3 and the turbulence column 4 means that the two are arranged at intervals along the extending direction of the flow channel, and can be specifically realized by arranging a turbulence column 4 between two adjacent pairs of turbulence parts 3, thereby alternately generating perturbations when the gas-liquid mixture flows through. The turbulence column 4 is arranged on the bottom wall, which means that its root is connected to the bottom wall of the flow channel, and its top extends into the internal space of the flow channel, so as to avoid blocking the top flow space and enhance the turbulence intensity of the bottom fluid at the same time.

[0053] Specifically, when the gas-liquid mixture enters the starting section of the turbulence channel 12 from the liquid inlet pipe 13 and the gas inlet pipe 14, it first passes through the turbulence part 3 to generate preliminary turbulence. Subsequently, the fluid enters the area provided with the turbulence column 4, and the turbulence column 4 cuts the bottom fluid, further dispersing the gas-liquid two phases. The alternately arranged turbulence part 3 and turbulence column 4 enable the fluid to experience multiple perturbation mode switches in the flow channel, extending the gas-liquid contact time. Since the turbulence column 4 is fixed on the bottom wall, it will not cause excessive blockage to the high-speed flowing bubble group at the top, thus balancing the relationship between the turbulence intensity and the flow resistance.

[0054] Compared with the prior art, traditional carbonization devices usually only adopt a single type of flow disturbance structure, such as only setting protrusions or only setting baffles. Such structures are prone to problems of excessive flow resistance or insufficient turbulence intensity when generating turbulence. In this solution, by alternately arranging the flow disturbance parts 3 and the flow disturbance columns 4, the fluid is disturbed in different height regions of the flow channel, which not only increases the gas-liquid contact area but also avoids the pressure loss caused by excessive contraction of the flow channel cross-section.

[0055] Through the above technical solution, the present application can achieve efficient dispersion of gas-liquid mixtures in a limited flow channel space. Especially for the problem of low carbon dioxide dissolution efficiency in bubble water machines, by optimizing the layout of the flow disturbance structure, while ensuring the compactness of the device, the carbonization concentration of bubble water is significantly improved. In addition, due to the fixed connection method of the flow disturbance column 4 to the bottom wall, this structure is not easily displaced or detached due to fluid impact during long-term use, which is beneficial to maintaining stable carbonization performance.

[0056] In one embodiment, please refer to Figure 2 and Figure 5 , the flow disturbance column 4 includes a main body and a protrusion part 42 protruding from the outer periphery of the column body 41, and the protrusion part 42 is used to generate turbulence to increase the gas-liquid contact area.

[0057] Specifically, the main body refers to the support structure constituting the flow disturbance column 4, which can be specifically realized by a cylindrical body 41 or a prism structure, serving as the basic carrier for installing the protrusion part 42. The protrusion part 42 refers to an irregular geometric structure protruding from the outer surface of the main body, which can be specifically realized by a spiral rib or a hemispherical protrusion in an annular array, forming local eddies by changing the fluid flow direction.

[0058] Specifically, when the gas-liquid mixture enters the flow disturbance channel 12, it flows through the surface of the flow disturbance column 4 with the protrusion part 42, and the fluid undergoes flow separation at the edge of the protrusion part 42 and forms a shear layer. The geometric characteristics of the protrusion part 42 cause the fluid to generate periodic shedding vortices, and this turbulent state prolongs the contact time of the gas-liquid two phases. The main body structure provides a stable installation foundation for the protrusion part 42 to ensure that the structure does not shift during fluid impact. The height and spacing of the protrusion part 42 are calculated to match the flow channel size, so that effective turbulence intensity can be maintained under different flow velocity conditions.

[0059] Compared with the prior art, traditional flow disturbance columns 4 usually adopt a smooth cylindrical body 41 or a simple prism structure, and only rely on the blocking effect of the column body 41 to generate limited turbulence. The introduction of the protrusion part 42 forms a secondary flow disturbance structure on the surface of the column body 41, enhancing the dissipation of fluid kinetic energy through geometric mutation points, and increasing the turbulence intensity of the gas-liquid mixture by two orders of magnitude.

[0060] Through the above technical solution, the present application effectively improves the gas-liquid mixing efficiency, and the dissolved amount of carbon dioxide in the sparkling water increases significantly. The multi-scale eddies generated by the convex portion 42 make the gas molecules more evenly dispersed in the liquid, shortening the mixing time while reducing gas escape, and finally obtaining a high-quality carbonated beverage with dense bubbles and stable concentration.

[0061] In one embodiment, please refer to Figure 4 and Figure 5 , the cross-section of the spoiler column 4 in its length direction is diamond-shaped.

[0062] It should be noted that the spoiler column 4 refers to a columnar structure provided on the bottom wall of the spoiler channel 12, which can be specifically formed by casting or stamping processes and is used to generate turbulence by blocking the gas-liquid flow.

[0063] Among them, the cross-section being diamond-shaped means that the cross-sectional shape along the length direction of the spoiler column 4 is diamond-shaped, which can be specifically realized by die forming or machining. The four sharp corners of the diamond can form multi-directional disturbances when the fluid passes by.

[0064] Specifically, when the gas-liquid mixture flows through the spoiler channel 12, the diamond-shaped cross-sectional structure causes asymmetric velocity changes of the fluid on both sides of the column 41. After the fluid contacts the acute angle of the diamond cross-section, the flow direction is forced to change, thereby forming multiple local eddies in the channel. These eddies further disrupt the laminar state of the gas-liquid mixture, promoting more sufficient contact and dissolution between the gas and the liquid. In addition, the symmetric characteristic of the diamond cross-section can balance the impact force of the fluid on the spoiler column 4, preventing the structure from shifting or deforming due to long-term stress.

[0065] Compared with the prior art, the traditional spoiler column 4 mostly uses circular or rectangular cross-sections. The circular cross-section can only guide the fluid through a single curved surface, resulting in limited turbulence intensity; although the right-angle edges of the rectangular cross-section can form certain disturbances, the fluid is prone to form stagnant areas at the right angles, reducing the flow efficiency. The diamond cross-section disperses the fluid impact through the sharp-corner structure and reduces the stagnant areas at the same time, enhancing the turbulence intensity while maintaining the overall fluidity of the fluid in the channel.

[0066] Through the above technical solution, the present application can enhance the turbulence effect of the gas-liquid mixture, improve the dissolution efficiency of the gas in the liquid, thereby solving the problem that the existing carbonator has a low concentration of sparkling water due to insufficient gas-liquid contact area, and meeting the user's demand for high-concentration sparkling water.

[0067] In one embodiment, please refer to Figure 4 , the cross-section of the spoiler portion 3 in its length direction is triangular.

[0068] Furthermore, a triangular cross-section means that the vertical plane along the extending direction of the spoiler part 3 presents a shape enclosed by three sides, and specifically, an isosceles triangle, a right triangle or other triangular structures can be adopted. For example, the tip of the triangle can face the fluid flow direction, and the bottom surface can be connected to the side wall of the spoiler channel 12. This structure can form an asymmetric turbulent region when the gas-liquid mixture flows, thereby increasing the contact area.

[0069] Specifically, when the gas-liquid mixture enters the spoiler channel 12 from the liquid inlet pipe 13 and the gas inlet pipe 14, the mixture flows along the spoiler channel 12 and impacts the spoiler part 3 with a triangular cross-section. Due to the sharp edges and inclined surfaces of the triangular cross-section, the fluid will generate separated flows with sudden direction changes when passing through the protrusions, forming local vortices. These vortices prompt the gas and liquid to collide violently, making the gas dissolve more fully in the liquid. For example, the bottom edge of the triangular cross-section can be set to be fixedly connected to the side wall, and the apex angle can be set to point to the fluid flow direction, thereby enhancing the turbulent effect while reducing the flow resistance.

[0070] Compared with the prior art, traditional spoiler structures mostly adopt rectangular or arc-shaped cross-sections. Such structures generate lower turbulent intensity and greater flow resistance. The triangular cross-section can form a more complex flow pattern in the same space through its geometric characteristics, and at the same time reduce the pressure drop loss caused by structural mutations, thereby improving the gas-liquid mixing efficiency.

[0071] Through the above technical solutions, the present application can enhance the turbulent intensity in the gas-liquid mixing process, make the gas disperse more evenly in the liquid, and further increase the dissolved gas concentration of the final bubble water. This solution realizes a significant increase in the gas-liquid contact area in a limited space by optimizing the cross-sectional shape of the spoiler part 3, thereby meeting the user's requirements for the taste concentration of bubble water.

[0072] In one embodiment, please refer to Figure 5 , the impeller 2 includes a wheel body 21 and a plurality of blades 22 arranged on the outer periphery of the wheel body 21. A plurality of rib plates 111 are protruding from the groove wall of the installation groove 11. When the impeller 2 rotates, the rib plates 111 are used to block the gas-liquid mixture to increase the gas-liquid contact area.

[0073] The present application further proposes that the impeller 2 includes a wheel body 21 and a plurality of blades 22 arranged on the outer periphery of the wheel body 21. A plurality of rib plates 111 are protruding from the groove wall of the installation groove 11. When the impeller 2 rotates, the rib plates 111 are used to block the gas-liquid mixture to increase the gas-liquid contact area.

[0074] Among them, the wheel body 21 refers to the central support structure of the impeller 2, and specifically, it can be realized by using metal or high-strength plastic materials, and is used to fix the blades 22 and provide rotational stability.

[0075] Among them, the blade 22 refers to a plate-like structure arranged along the outer periphery of the wheel body 21, which can be specifically implemented in an arc shape or a straight plate shape, and is used to drive the gas-liquid mixture to generate centrifugal motion during rotation.

[0076] Among them, the rib plate 111 refers to a strip-shaped protrusion extending from the groove wall of the installation groove 11 towards the inside, which can be specifically implemented by integrally forming with the groove wall, and is used to block the flow path of the gas-liquid mixture when the impeller 2 rotates, so as to extend the contact time.

[0077] Specifically, when the impeller 2 rotates in the installation groove 11, the blade 22 drives the gas-liquid mixture to move at a high speed, forming a centrifugal flow. The rib plates 111 protrude from the groove wall of the installation groove 11 at intervals and generate periodic blockages when the gas-liquid mixture flows through. This blocking effect forces the flow direction of the gas-liquid mixture to change, forming local turbulence, further refining the bubble size and increasing the gas-liquid contact area. At the same time, the presence of the rib plates 111 extends the residence time of the gas-liquid mixture in the installation groove 11, enabling carbon dioxide to dissolve sufficiently in the liquid.

[0078] Compared with the prior art, in the traditional solution, only the centrifugal force generated by the rotation of the impeller 2 is relied on to achieve gas-liquid mixing, and no blocking structures such as the groove wall rib plates 111 are provided, resulting in a short gas-liquid contact time and uneven bubble distribution. In this solution, through the synergistic effect of the rib plates 111 and the impeller 2, the mixing efficiency and dissolution effect are significantly improved.

[0079] Through the above technical solution, the present application can effectively solve the problem of low concentration caused by insufficient gas-liquid contact in the existing bubble water machine. The interference of the rib plates 111 on the flow path enhances the turbulence intensity, enabling carbon dioxide to dissolve more fully in the liquid, and finally obtaining bubble water with uniform bubble distribution and rich taste.

[0080] In one embodiment, please refer to Figure 2 , the flow-through carbonator 100 further includes a cover plate 5 and a gasket 6. The cover plate 5 is arranged on one side of the main body portion 1 where the turbulence channel 12 is opened, and the cover plate 5 is used to seal the main body portion 1; the gasket 6 is arranged between the main body and the cover plate 5, and the gasket 6 is used to provide sealing for the cover plate 5 and the main body.

[0081] It should be noted that the cover plate 5 refers to a plate-shaped component covering the outside of the main body 1. Specifically, it can be made of metal or high-strength plastic and is fixed to the main body 1 by bolts or snap-fastening methods, serving to enclose the installation groove 11 and the flow disturbance channel 12. The gasket 6 refers to an elastic material layer provided between the main body and the cover plate 5. Specifically, it can be made of rubber or silica gel and fills the gap between the main body and the cover plate 5 through compression deformation to prevent the leakage of the gas-liquid mixture. The mating portion 51 refers to a convex structure on the inner side of the cover plate 5. Specifically, it can be realized by an annular boss matching the shape of the installation groove 11, which is used to accurately align with the installation groove 11 and limit the installation position of the cover plate 5. The relief groove refers to a groove structure opened on the gasket 6. Specifically, it can be formed by stamping or injection molding processes, so that the gasket 6 will not interfere with the mating portion 51 when being compressed, ensuring that the gasket 6 evenly adheres to the main body and the cover plate 5.

[0082] Specifically, through the positioning cooperation between the mating portion 51 of the cover plate 5 and the installation groove 11, the alignment of the gas-liquid channels during installation is ensured. At the same time, the relief groove design of the gasket 6 avoids the accumulation of the sealing material in the area of the mating portion 51, enabling the gasket 6 to evenly distribute pressure during the pressing process of the cover plate 5. The combined structure of the cover plate 5 and the gasket 6 forms a double sealing barrier outside the main body 1, preventing both the leakage of the gas-liquid mixture from the installation groove 11 to the outside and the entry of external impurities into the flow disturbance channel 12. The mating portion 51 contacts the side wall of the installation groove 11 during the installation process, further restricting the relative displacement between the cover plate 5 and the main body and improving the structural stability.

[0083] Compared with the prior art, the sealing structure of traditional carburetors usually adopts a single rubber gasket or the direct pressing method with bolts, which is prone to uneven sealing due to installation deviation and cannot effectively solve the sealing interference problem in the area of the mating portion 51. Through the collaborative design of the mating portion 51 and the relief groove in this application, the deformation process of the gasket 6 is controllable, avoiding structural misalignment while ensuring the sealing performance. Compared with the split sealing scheme, the integrated installation method of the cover plate 5 and the gasket 6 reduces the number of parts and the assembly complexity.

[0084] Through the above technical solutions, this application can effectively prevent the leakage of the gas-liquid mixture from the connection between the installation groove 11 and the cover plate 5 under high-pressure conditions, ensuring the pressure stability of the carbonization process. The relief groove design of the gasket 6 eliminates the risk of local sealing failure caused by the extrusion of the mating portion 51 and extends the service life of the sealing material. The positioning cooperation between the mating portion 51 and the installation groove 11 improves the equipment assembly accuracy and reduces the performance fluctuations caused by installation errors.

[0085] In one embodiment, please refer to Figure 6, on the side of the cover plate 5 facing the main body, a fitting portion 51 is protruded, and the fitting portion 51 is used to cooperate with the installation groove 11. The gasket 6 is provided with an avoidance groove, and the avoidance groove is used to avoid the fitting portion 51.

[0086] Specifically, the fitting portion 51 refers to a convex structure on the side of the cover plate 5 facing the main body, and can be specifically implemented by an annular flange or a local boss. Its outer contour shape matches the edge of the notch of the installation groove 11, and is used to guide the cover plate 5 to be coaxially positioned with the main body during assembly.

[0087] Among them, the avoidance groove refers to a recessed area on the gasket 6 corresponding to the fitting portion 51, and can be specifically implemented by molding with an elastic material. The groove depth is slightly larger than the height of the fitting portion 51, and is used to prevent the fitting portion 51 from causing excessive extrusion deformation of the gasket 6 when the cover plate 5 presses the gasket 6.

[0088] Specifically, the cover plate 5 is embedded into the edge of the notch of the installation groove 11 through the fitting portion 51 to form a radial limit constraint. At the same time, the avoidance groove wraps the outer circumference of the fitting portion 51, so that the gasket 6 is uniformly pressed. When the cover plate 5 and the main body are fastened by bolts, the cooperation between the fitting portion 51 and the installation groove 11 can prevent the gasket 6 from laterally shifting under the action of pressure, and the avoidance groove releases the local stress concentration of the fitting portion 51 on the gasket 6, avoiding permanent deformation of the gasket 6 due to excessive compression.

[0089] Compared with the prior art, only a flat gasket 6 is relied on to achieve sealing between the cover plate 5 and the main body of the traditional carburetor, lacking a positioning structure, and it is easy to cause misalignment and air leakage of the gasket 6 due to assembly deviation. Through the synergistic effect of the fitting portion 51 and the avoidance groove in this solution, both the precise alignment of the cover plate 5 and the main body is achieved, and the uniform compression state of the gasket 6 is maintained, solving the problems of sealing failure and low installation efficiency.

[0090] Through the above technical solution, the present application effectively enhances the sealing reliability of the carburetor under high-pressure conditions, avoids the leakage of the gas-liquid mixture from the joint of the cover plate 5 and the main body, and at the same time simplifies the manual adjustment steps in the assembly process, improving the carburetion efficiency and the service life of the equipment.

[0091] In an embodiment, please refer to Figure 2 , a limiting portion is protruded at the end of the impeller 2, and the limiting portion is used to increase the distance between the blade 22 and the cover plate 5.

[0092] Among them, the limiting part refers to an annular flange structure extending axially along the end face of the impeller 2, which can be specifically realized by injection molding or machining. This structure is used to form a gap between the impeller 2 and the cover plate 5. Among them, the gap refers to the axial space between the blade 22 and the cover plate 5, which can be specifically adjusted by changing the height of the limiting part. This gap is used to prevent the blade 22 from directly contacting the cover plate 5 while allowing the gas-liquid mixture to flow fully.

[0093] Specifically, during the rotation of the impeller 2, the limiting part contacts the surface of the cover plate 5, forming a fixed distance between the free end of the blade 22 and the cover plate 5. Thus, after the gas-liquid mixture enters the installation groove 11, the blade 22 will not reduce its efficiency due to friction with the cover plate 5 during rotation. At the same time, this gap provides sufficient flow space for the mixture, preventing local blockage caused by too close contact surfaces.

[0094] In some specific embodiments, the limiting part can be designed as a continuous annular protrusion or a block-shaped protrusion distributed at intervals. For example, the annular protrusion can be integrally formed on the end face of the impeller 2 by an injection molding process, and its height can be 0.5 mm to 2 mm to adapt to the thickness of different models of cover plates 5.

[0095] Compared with the prior art, the traditional impeller 2 does not have a limiting part, resulting in a lack of a stable gap between the blade 22 and the cover plate 5. After long-term operation, friction is likely to occur due to wear or deformation, reducing the mixing efficiency. This solution physically isolates the blade 22 from the cover plate 5 through the limiting part, avoiding direct contact and ensuring a stable flow path for the gas-liquid mixture.

[0096] Through the above technical solution, this application solves the problem of frictional loss caused by too small a gap between the blade 22 and the cover plate 5, reduces the flow resistance of the gas-liquid mixture, improves the uniformity of gas-liquid contact during the carbonization process, and ultimately improves the concentration and taste of the bubble water.

[0097] In one embodiment, please refer to Figure 3 , a sealing groove 15 is formed by recessing one side of the main body. A sealing protrusion 16 is arranged in the sealing groove 15, and the sealing protrusion 16 abuts against the sealing gasket 6 to provide sealing.

[0098] Among them, the sealing groove 15 refers to a recessed structure arranged on one side of the main body, which can be specifically formed by injection molding or machining, and is used to accommodate the sealing protrusion 16 and provide a positioning space for the sealing gasket 6. The sealing protrusion 16 refers to a protrusion structure arranged in the sealing groove 15, which can be integrally formed with an elastic material or independently installed, and forms a sealing interface through extrusion contact with the sealing gasket 6 to prevent the leakage of the gas-liquid mixture.

[0099] Specifically, the concave shape of the sealing groove 15 matches the shape of the sealing gasket 6. When the cover plate 5 is installed on the main body by fasteners, the sealing gasket 6 is compressed and fills the space of the sealing groove 15. The sealing protrusion 16 further increases the local contact pressure when the sealing gasket 6 is compressed, so that the sealing interface remains stable under different temperature and pressure conditions. Therefore, when the gas-liquid mixture flows in the installation groove 11 and the spoiler channel 12, the sealing structure effectively blocks the external environment, prevents gas escape or liquid leakage, and ensures that the pressure of the carbonization process is maintained.

[0100] Compared with the prior art, the traditional sealing structure usually relies on plane contact or a single sealing gasket 6 to achieve sealing, which is prone to sealing failure due to processing errors or material deformation. This solution uses a combination design of the sealing groove 15 and the sealing protrusion 16 to make the sealing gasket 6 evenly stressed during the compression process, and at the same time, the local reinforcement effect of the protrusion compensates for the microscopic unevenness of the contact surface, thereby improving the sealing reliability.

[0101] Through the above technical solution, the present application solves the problem of gas-liquid mixture leakage caused by poor sealing, thereby maintaining the internal pressure of the carbonizer stable, improving the gas dissolution efficiency, and effectively improving the concentration of bubble water. The matching structure of the sealing groove 15 and the sealing protrusion 16 simplifies the assembly process and reduces the maintenance cost caused by sealing failure.

[0102] In one embodiment, see Figure 2 A shaft body is arranged in the installation groove 11 , and the shaft body is coaxially arranged with the installation groove 11 , and the shaft body is used to provide support for the impeller 2 .

[0103] The present invention also provides a flow carbonizer 100, see Figure 7 The over-flow carbonizer 100 includes a venturi tube 7, a main body 1 and an impeller 2, wherein the venturi tube 7 is used to mix liquid and gas, a mounting groove 11 is provided in the middle of the main body 1, a flow disturbance channel 12 is provided on the periphery of the mounting groove 11, and the flow disturbance channel 12 includes a starting section and a tail section, a liquid inlet pipe 13 is provided on the outside of the main body 1, one end of the liquid inlet pipe 13 is connected to the downstream of the venturi tube 7, the other end of the liquid inlet pipe 13 is connected to the starting section, and the tail section is connected to the mounting groove 11; the impeller 2 is rotatably arranged in the mounting groove 11; wherein, a plurality of pairs of flow disturbance parts 3 are protrudingly provided in the flow disturbance channel 12 along its extension direction, the flow disturbance part 3 is connected to the side wall of the flow disturbance channel 12, and the flow disturbance part 3 is used to generate turbulence to increase the gas-liquid contact area.

[0104] Compared with the previous technical solution, in order to further improve the mixing effect of the cross-flow carbonator in this embodiment, a Venturi tube 7 is further provided upstream of the main body 1 for preliminarily mixing gas and fluid. The Venturi tube 7 includes a tube portion 71 and a suction tube 72. Carbon dioxide enters from the suction tube 72 of the Venturi tube 7, and water flow enters from one end of the tube portion 71, so as to form bubble water after mixing. The mixed bubble water flows into the main body 1 for further filtration.

[0105] The Venturi tube 7 can be injection molded from food-grade POM plastic and has good wear resistance and corrosion resistance. The Venturi tube 7 is used to mix gas and liquid. The CO2 gas in the CO2 gas cylinder will flow into the Venturi tube 7 through the intake end, and the water in the water storage tank will flow into the Venturi tube 7 through the water inlet end. Under the action of the Venturi tube 7, the CO2 gas will be inhaled into the water and mixed and dissolved by using the Venturi effect. The tube portion 71 is integrally cylindrical and can be injection molded integrally from food-grade POM plastic. Of course, in other embodiments, the various components of the tube body can be separately arranged for easy production and processing.

[0106] In one embodiment, please refer to Figure 4 and Figure 5 , a plurality of spoiler columns 4 are arranged along the extending direction of the spoiler channel 12, the plurality of spoiler portions 3 and the plurality of spoiler columns 4 are alternately arranged, and the spoiler columns 4 are arranged on the bottom wall of the spoiler channel 12.

[0107] In one embodiment, please refer to Figure 2 and Figure 5 , the spoiler column 4 includes a column body 41 and a protrusion portion 42 protruding on the outer periphery of the column body 41, and the protrusion portion 42 is used to generate turbulence to increase the gas-liquid contact area.

[0108] Specifically, the column body 41 refers to the support structure constituting the spoiler column 4, which can be specifically implemented by a cylindrical body 41 or a prism structure as the basic carrier for installing the protrusion portion 42. The protrusion portion 42 refers to an irregular geometric structure protruding on the outer surface of the column body 41, which can be specifically implemented by a spiral rib or a hemispherical protrusion in a circular array, and local eddies are formed by changing the fluid flow direction.

[0109] Specifically, when the gas-liquid mixture enters the spoiler channel 12, it flows through the surface of the spoiler column 4 with the protrusion portion 42, and the fluid undergoes flow separation at the edge of the protrusion portion 42 and forms a shear layer. The geometric characteristics of the protrusion portion 42 cause the fluid to generate periodic shedding vortices, and this turbulent state prolongs the contact time of the gas-liquid two-phase. The column body 41 structure provides a stable installation foundation for the protrusion portion 42 to ensure that the structure does not shift during fluid impact. The height and spacing of the protrusion portion 42 are calculated to match the flow channel size, so that an effective turbulent intensity can be maintained under different flow velocity conditions.

[0110] Compared with the prior art, the traditional spoiler column 4 usually adopts a smooth cylinder or a simple prism structure, and only relies on the blocking effect of the column body 41 to generate limited turbulence. The introduction of the protrusion 42 forms a secondary turbulent flow structure on the surface of the column body 41, and enhances the dissipation of fluid kinetic energy through the geometric mutation point, so that the turbulence intensity of the gas-liquid mixture is increased by two orders of magnitude.

[0111] In one embodiment, please refer to Figure 4 that the cross-section of the spoiler column 4 in its length direction is diamond-shaped.

[0112] It should be noted that the spoiler column 4 refers to a columnar structure arranged on the bottom wall of the spoiler channel 12, and can be specifically formed by casting or stamping processes, and is used to generate turbulence by blocking the gas-liquid flow.

[0113] Among them, the cross-section being diamond-shaped means that the cross-sectional shape along the length direction of the spoiler column 4 is diamond-shaped, and can be specifically realized by die forming or machining. The four sharp corners of the diamond can form multi-directional disturbances when the fluid passes through.

[0114] Specifically, when the gas-liquid mixture flows through the spoiler channel 12, the diamond-shaped cross-sectional structure causes asymmetric velocity changes of the fluid on both sides of the column body. After the fluid contacts the acute angle of the diamond cross-section, the flow direction is forcibly changed, thereby forming multiple local eddies in the channel. These eddies further disrupt the laminar state of the gas-liquid mixture, promoting more sufficient contact and dissolution between the gas and the liquid. In addition, the symmetric characteristics of the diamond cross-section can balance the impact force of the fluid on the spoiler column 4, avoiding the structure from shifting or deforming due to long-term stress.

[0115] Compared with the prior art, the traditional spoiler column 4 mostly adopts a circular or rectangular cross-section. The circular cross-section can only guide the fluid through a single curved surface, generating limited turbulence intensity; although the right-angle edge of the rectangular cross-section can form certain disturbances, the fluid is likely to form a stagnant area at the right angle, reducing the flow efficiency. The diamond cross-section disperses the fluid impact through the sharp corner structure and reduces the stagnant area at the same time, while enhancing the turbulence intensity and maintaining the overall fluidity of the fluid in the channel.

[0116] Through the above technical solutions, the present application can enhance the turbulent effect of the gas-liquid mixture, improve the dissolution efficiency of the gas in the liquid, thereby solving the problem that the existing carbonator has a low bubble water concentration due to insufficient gas-liquid contact area, and meeting the user's demand for high-concentration bubble water.

[0117] The present invention also proposes a bubble water device, which includes an overcurrent carbonator 100. The specific structure of the overcurrent carbonator 100 refers to the above embodiment. Since this bubble water device adopts all the technical solutions of the above all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0118] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
