[0042] In the current general high-pressure carbonation tank technology in this field, the concentration of carbon dioxide is increased by increasing the pressure inside the tank. However, this increases the safety requirements for the equipment and also increases the requirements for the water pump, resulting in more cost investment and an increase in the volume of the equipment. Therefore, there is an urgent need in this field for a more advanced solution to solve the above problems, which can increase the concentration without increasing the requirements for the water pump.

[0043] The present invention provides a carbonator 100, which is used in a sparkling water device to mix carbon dioxide gas and water to make sparkling water for users to drink.

[0044] Please refer to Figures 1 to 4 , in an embodiment of the present invention, the carbonator 100 includes a gas mixing box body 10, an air inlet pipe 30, a liquid inlet pipe 20, a liquid outlet pipe 40, and an impeller 50. The gas mixing box body 10 is in a quadrilateral shape, and there is a connected static turbulence channel 11 and a dynamic turbulence chamber 12 inside the gas mixing box body 10. The static turbulence channel 11 has a multi-segmented structure connected in sequence. The air inlet pipe 30 and the liquid inlet pipe 20 are both connected to the front end of the static turbulence channel 11. The liquid outlet pipe 40 is connected to the rear end of the dynamic turbulence chamber 12. The impeller 50 is rotatably arranged in the dynamic turbulence chamber 12. The static turbulence channel 11 has a left side surface 111 and a right side surface 112. A plurality of first turbulence protrusions 13 protrude from the left side surface 111 towards the right side surface 112, and a plurality of second turbulence protrusions 14 protrude from the right side surface 112 towards the left side surface 111. Each first turbulence protrusion 13 and second turbulence protrusion 14 extends from the bottom wall of the static turbulence channel 11 to its top wall. The plurality of first turbulence protrusions 13 are spaced apart along the extending direction of the static turbulence channel 11 on the left side surface 111, and the plurality of second turbulence protrusions 14 are spaced apart along the extending direction of the static turbulence channel 11 on the right side surface 112. The extending direction of the static turbulence channel 11 is the direction of fluid flow inside it.

[0045] Specifically, in the present embodiment, the mixing box body 10 is quadrilateral, and the internal structure is the key to achieve gas-liquid mixing. A static turbulence channel 11 and a dynamic turbulence chamber 12 are provided therein. The static turbulence channel 11 is designed as a multi-segment structure connected in sequence. This unique shape increases the length and complexity of the flow path of the gas-liquid mixture in the channel. The air inlet pipe 30 and the liquid inlet pipe 20 are both connected to the front end of the static turbulence channel 11. The air inlet pipe 30 is responsible for inputting carbon dioxide gas, and the liquid inlet pipe 20 is used to input the liquid to be carbonized (usually water). The two introduce the gas and liquid into the static turbulence channel 11 here to start the mixing process. The liquid outlet pipe 40 is connected to the rear end of the dynamic turbulence chamber 12, and its function is to output the gas-liquid mixture that has been fully mixed and carbonized, that is, the finished bubble water. The static spoiler channel 11 has a left side 111 and a right side 112, the left side 111 protrudes a plurality of first spoiler protrusions 13 toward the right side 112, the right side 112 protrudes a plurality of second spoiler protrusions 14 toward the left side 111, and each of the first spoiler protrusions 13 and the second spoiler protrusions 14 extends from the bottom wall to the top wall of the static spoiler channel 11. These spoiler protrusions construct a complex flow field environment in the static spoiler channel 11.

[0046] The operation process of this embodiment is described below:

[0047] In the static turbulence channel 11, the carbon dioxide and water respectively input from the air inlet pipe 30 and the liquid inlet pipe 20 are efficiently initially mixed due to the presence of the multi-segment structure, the first turbulence protrusion 13 and the second turbulence protrusion 14. The carbon dioxide gas is divided into tiny bubbles and evenly dispersed in the liquid, and the gas-liquid contact area is greatly increased, which lays a good foundation for the subsequent carbonization process. After the gas-liquid two-phase fluid enters the dynamic turbulence chamber 12, the impeller 50 rotates to generate strong stirring force and centrifugal force. On the one hand, the stirring action further breaks up the bubbles, allowing the carbon dioxide to contact with the water more fully and accelerate dissolution; on the other hand, the centrifugal force causes the gas and liquid to form a circulation flow in the dynamic turbulence chamber 12, further enhancing the mixing effect and improving the carbon dioxide concentration and uniformity of the bubble water. The finally prepared bubble water has a rich taste and delicate and long-lasting bubbles.

[0048] The multi-segment static turbulence channel 11 of the present application increases the flow path length of the gas-liquid mixture. During the flow of the gas-liquid, the direction is constantly changed, and the channel wall surface is impacted multiple times. This frequent turning and impact cause the gas and liquid to rub and collide with each other, thereby promoting gas dispersion and mixing. The first turbulence protrusion 13 and the second turbulence protrusion 14 are staggered on both sides of the static turbulence channel 11. When the gas-liquid mixture flows through, the turbulence protrusions divide the gas-liquid flow, changing the flow direction and velocity of the gas-liquid. Vortices are formed behind both the first turbulence protrusion 13 and the second turbulence protrusion 14. The gas-liquid mixing in the vortex region is more intense, greatly increasing the gas-liquid contact area, enabling carbon dioxide to be better dispersed in the liquid, and improving the premixing effect. The impeller 50 rotates in the dynamic turbulence chamber 12, and the blades 52 push the gas-liquid mixture to move, generating a strong stirring effect. This stirring action further breaks and mixes the gas-liquid after preliminary mixing in the static turbulence channel 11, making the bubble size smaller and the distribution more uniform, and accelerating the dissolution process of carbon dioxide in the liquid.

[0049] In summary, the present application can enhance the gas-liquid fluid disturbance to promote physical dissolution, produce bubble water with a higher concentration and lower cost, have lower requirements for the water pump, and reduce the volume of the bubble water device.

[0050] Furthermore, the first turbulence protrusion 13 and the second turbulence protrusion 14 are arranged in a one-to-one correspondence; and / or, the shapes and sizes of the first turbulence protrusion 13 and the second turbulence protrusion 14 are the same.

[0051] Specifically, in this embodiment, the first turbulence protrusion 13 and the second turbulence protrusion 14 are arranged in a one-to-one correspondence, so that when the gas-liquid mixture flows through, it can be accurately divided into corresponding fine streamlets. When the gas-liquid flow impacts the first turbulence protrusion 13 on one side, it will be divided into several small streamlets that bypass the protrusion part, and the second turbulence protrusion 14 on the opposite side can guide these small streamlets to converge in the middle area of the channel. This accurate flow splitting and convergence mechanism greatly increases the collision and mixing opportunities between the gas and liquid, enabling the gas and liquid to contact and fuse with each other more fully. Due to the relative positions of the first turbulence protrusion 13 and the second turbulence protrusion 14, strong interactions will occur when the gas-liquid small streamlets converge, forming complex turbulence and vortices. These turbulence and vortices can continuously stir the gas-liquid, further breaking the gas-liquid interface, promoting the diffusion and dissolution of carbon dioxide gas in the liquid, and thus significantly improving the efficiency and quality of gas-liquid mixing.

[0052] The first spoiler protrusion 13 and the second spoiler protrusion 14 have the same shape and size, forming a symmetric flow field environment within the static spoiler channel 11. Regardless of which side of the channel the gas-liquid mixture enters from, the spoiler effect it experiences is the same. This ensures that the gas and liquid can be evenly mixed across the entire cross-section of the channel, avoiding uneven mixing problems caused by overly strong or weak spoiler effects on one side, and making the final prepared bubble water more uniform and stable in terms of carbon dioxide concentration and taste. The spoiler protrusions with the same shape and size have the same effect on the gas-liquid mixture, and can comprehensively divide, disturb, and mix the gas and liquid. From the top to the bottom and from the left to the right of the channel, the gas and liquid can receive sufficient and consistent spoiler treatment, further enhancing the mixing uniformity and the quality stability of the bubble water.

[0053] Furthermore, the cross-section of the first spoiler protrusion 13 in the length direction is an isosceles triangle; and / or, the cross-section of the second spoiler protrusion 14 in the length direction is a waist triangle.

[0054] Specifically, in this embodiment, the cross-sections of the first spoiler protrusion 13 and the second spoiler protrusion 14 in the length direction are isosceles triangles. The sharp apex angle of the isosceles triangle can efficiently divide the gas-liquid mixed flow like a blade. When the gas-liquid mixture flows through the first spoiler protrusion 13 and the second spoiler protrusion 14, the apex angle quickly divides the gas-liquid flow into two parts, causing it to flow to both sides. This division method is sharper and more direct compared to other shapes (such as circular or square), and can more effectively break up the originally larger gas-liquid masses, increasing the contact area between the gas and liquid. The symmetry of the isosceles triangle enables the gas-liquid flow to be more evenly divided to both sides after being divided. The liquid flows on both sides have similar velocity and pressure distributions during the flow process, which helps to form a more stable and uniform flow field within the channel, avoiding over-concentration or dispersion of the gas and liquid in local areas, and creating good conditions for subsequent full mixing. When the gas-liquid flow bypasses the isosceles triangle protrusion, obvious vortices will form behind it. Due to the special shape of the isosceles triangle, the formation of the vortices is more regular and intense. These vortices can continuously stir the gas and liquid, making the interaction between the gas and liquid more intense, and promoting the dispersion and dissolution of carbon dioxide gas in the liquid. Multiple isosceles triangle protrusions are arranged in sequence, causing the gas-liquid flow to continuously experience the processes of division, confluence, and vortex formation within the channel, thereby significantly enhancing the intensity of turbulence. Under turbulent conditions, the mixing of the gas and liquid is more sufficient and uniform, which can effectively improve the carbonation effect and quality of the bubble water.

[0055] Moreover, the shape of the isosceles triangle is relatively simple and is convenient for processing and forming during the manufacturing process. Whether using methods such as injection molding, casting, or machining, it is relatively easy to produce isosceles triangle protrusions that meet the requirements, reducing the manufacturing cost and production difficulty.

[0056] Furthermore, the static turbulence channel 11 includes a first channel 11a, a second channel 11b, and a third channel 11c that are connected in sequence; the third channel 11c is substantially parallel to the first channel 11a, and the dynamic turbulence chamber 12 is located between the first channel 11a and the third channel 11c.

[0057] Specifically, the first channel 11a, the second channel 11b, and the third channel 11c are connected in sequence, significantly extending the flow path of the gas-liquid mixture within the static turbulence channel 11. After the gas-liquid enters the first channel 11a from the gas inlet pipe 30 and the liquid inlet pipe 20, during the process of flowing through the meandering second channel 11b and finally reaching the third channel 11c, there is more time and opportunity for them to come into contact and mix with each other. As the path extends, the gas can be more fully dispersed in the liquid, improving the dissolution efficiency of carbon dioxide and laying a good foundation for further mixing and carbonation in the subsequent dynamic turbulence chamber 12. For example, when the gas-liquid flows in the channel, it constantly changes direction, increasing the friction and collision between the gas and the liquid, causing the gas to be divided into smaller bubbles and more evenly distributed in the liquid. The design of the third channel 11c being substantially parallel to the first channel 11a helps to form a relatively stable and predictable flow field within the static turbulence channel 11. During the process of the gas-liquid mixture flowing from the first channel 11a through the second channel 11b to the third channel 11c, the changes in the flow direction and velocity have a certain regularity. This stable flow field distribution makes the gas-liquid mixing more uniform, avoiding the gas-liquid separation or insufficient mixing caused by a disordered flow field. By setting the first channel 11a and the third channel 11c to be parallel, the energy transfer of the gas-liquid mixture is more efficient. Due to the parallel arrangement of the channels, the flow of the gas-liquid between different channels has a certain symmetry, enabling the energy to be more evenly distributed between the gas and the liquid. This energy transfer helps to enhance the gas-liquid mixing effect and accelerate the carbon dioxide dissolution process. For example, the high-speed flowing gas-liquid affects each other between the parallel channels, generating turbulence and vortices that can better stir the gas-liquid and promote the diffusion of carbon dioxide.

[0058] The dynamic turbulence chamber 12 is located between the first channel 11a and the third channel 11c, enabling the gas-liquid mixture to enter the dynamic turbulence chamber 12 in a timely manner for further enhanced mixing after the preliminary mixing in the static turbulence channel 11. The static turbulence channel 11 provides a gas-liquid mixture with preliminary uniform mixing for the dynamic turbulence chamber 12, while components such as the impeller 50 in the dynamic turbulence chamber 12 stir and mix the gas-liquid more strongly. This layout enables the static mixing and the dynamic mixing to cooperate with each other, giving full play to the advantages of the two mixing methods and greatly improving the overall mixing efficiency of the carbonator 100 and the quality of the bubble water. For example, after the preliminary mixed gas-liquid flowing out of the third channel 11c enters the dynamic turbulence chamber 12, the rotation of the impeller 50 can further break up the bubbles, enabling carbon dioxide to come into more full contact with the liquid and enhancing the carbon dioxide concentration and taste of the bubble water.

[0059] The dynamic turbulence chamber 12 is arranged between the first channel 11a and the third channel 11c, making reasonable use of the space inside the gas-liquid mixing box body 10. This compact layout design optimizes the gas-liquid mixing process without increasing the volume of too many devices, improving the integration and practicality of the device. For example, in practical applications, this layout can make the carbonator 100 more miniaturized, facilitating installation and use, while not affecting its mixing and carbonization effects.

[0060] Furthermore, the liquid inlet pipe 20 is arranged along the direction parallel to the fluid flow in the first channel 11a; and / or, the gas inlet pipe 30 is arranged along the direction perpendicular to the fluid flow in the first channel 11a.

[0061] Specifically, the liquid inlet pipe 20 is arranged along the direction parallel to the fluid flow in the first channel 11a, enabling the liquid to enter the first channel 11a smoothly and steadily. When the liquid flows in from the liquid inlet pipe 20, its flow direction is consistent with the subsequent gas-liquid mixture flow direction in the first channel 11a, reducing the impact and turbulence generated by sudden direction changes and contributing to maintaining the stability of the gas-liquid mixing process. The gas inlet pipe 30 is arranged perpendicular to the fluid flow direction in the first channel 11a. When carbon dioxide gas enters from the gas inlet pipe 30, it will meet the liquid flowing in from the liquid inlet pipe 20 in a perpendicular impact manner. This perpendicular impact can quickly break the original flow state of the gas, enabling the gas to enter the liquid flow in a more dispersed form. Compared with parallel gas inlet, perpendicular gas inlet can make the gas more evenly distributed across the cross-section of the liquid, avoiding the problem of gas concentration in local areas, greatly increasing the contact area between gas and liquid, and improving the mixing efficiency. Perpendicular gas inlet will cause strong turbulence in the gas-liquid intersection area. When the gas vertically impacts the liquid, velocity differences and pressure differences will be generated, thus forming complex vortex and turbulent flow structures. These turbulences can continuously stir the gas and liquid, further enhancing the interaction between gas and liquid, enabling the carbon dioxide gas to dissolve in the liquid faster, and improving the quality of the bubble water.

[0062] In summary, the parallel arrangement of the liquid inlet pipe 20 and the perpendicular arrangement of the gas inlet pipe 30 cooperate with each other to jointly optimize the gas-liquid mixing process. The liquid inlet pipe 20 ensures the smooth input and preliminary mixing of the liquid, while the gas inlet pipe 30 efficiently disperses the gas into the liquid and triggers turbulence to strengthen the mixing. The two work together, enabling efficient mixing of gas and liquid in the first channel 11a, providing good starting conditions for further mixing and carbonization in the static turbulence channel 11 and the dynamic turbulence chamber 12, and improving the working efficiency of the entire carbonator 100 and the production quality of the bubble water.

[0063] Furthermore, there is also a transition channel in the gas-liquid mixing box for connecting between the third channel 11c and the dynamic turbulence chamber 12; the bottom wall of the transition channel is higher than the bottom wall of the third channel 11c.

[0064] Specifically, when the gas-liquid mixture flows from the third channel 11c to the transition channel, due to the elevation of the bottom wall of the transition channel, the flow path of the gas-liquid mixture changes. When the gas-liquid mixture flows from the third channel 11c to the transition channel, due to the elevation of the bottom wall of the transition channel, the flow path of the gas-liquid mixture changes. Under the action of gravity, the liquid with a larger density has a tendency to flow downward, while the gas with a smaller density is more likely to accumulate upward. This gas-liquid separation effect makes the gas relatively concentrated in the upper region of the transition channel, creating conditions for more sufficient mixing with the liquid in the subsequent dynamic turbulence chamber 12. For example, the tiny bubbles originally dissolved in the liquid may gradually aggregate to form larger bubbles during this process, which is convenient for being further broken and dispersed in the dynamic turbulence chamber 12. The flow space of the gas-liquid mixture in the transition channel changes. During the upward accumulation of the gas, it will be compressed to a certain extent. This pre-compression slightly increases the pressure of the gas. According to Henry's law, at a certain temperature, the solubility of a gas in a liquid is proportional to the partial pressure of the gas. Therefore, the increase in gas pressure helps to improve the solubility of carbon dioxide in the liquid, thereby enhancing the carbonation effect of the bubble water.

[0065] The elevation of the bottom wall of the transition channel changes the flow velocity and direction of the gas-liquid mixture. When the gas-liquid mixture enters the transition channel, the flow velocity will be adjusted due to the change in the cross-sectional area of the channel and the elevation of the bottom wall. This adjustment of the flow velocity can enable the gas-liquid to enter the dynamic turbulence chamber 12 at a more appropriate speed, avoiding affecting the mixing effect in the dynamic turbulence chamber 12 due to too fast or too slow flow velocity. At the same time, the change in the flow direction of the gas-liquid also helps to form a flow pattern more conducive to mixing when the gas-liquid enters the dynamic turbulence chamber 12.

[0066] In summary, the design that the bottom wall of the transition channel is higher than the bottom wall of the third channel 11c improves the gas-liquid mixing efficiency of the carbonator 100 and the carbonation quality of the bubble water by promoting gas-liquid separation, optimizing the gas-liquid entry state, and reducing liquid impact.

[0067] Furthermore, the widths of the first channel 11a, the second channel 11b, and the third channel 11c are in the range of 3 mm - 5 mm; and / or, the width of the transition channel is within 0.8 mm - 1.2 mm.

[0068] Specifically, in this embodiment, the width of the static turbulence channel 11 is restricted. This width range enables the gas-liquid mixture to have a moderate flow resistance when flowing through the channel. When the gas-liquid mixture flows through the channel, this resistance promotes more friction and collision between the gas and the liquid. The appropriate channel width is conducive to forming a stable turbulent flow when the gas-liquid mixture flows through. Within this width range, the velocity distribution and pressure change of the gas-liquid flow can trigger complex vortex and turbulent structures. These turbulent flows continuously stir the gas and the liquid, making the gas-liquid mixture more uniform, further breaking the gas-liquid interface, accelerating the diffusion of carbon dioxide in the liquid, and improving the quality of the bubble water.

[0069] A width of 3 mm - 5 mm can ensure that the gas-liquid mixture passes through the channel at an appropriate flow rate. If the channel is too wide, the gas-liquid flow rate may be too fast, resulting in insufficient gas-liquid mixing time and inability to fully dissolve carbon dioxide; while if the channel is too narrow, the flow rate will be too small, affecting the production efficiency. This width range balances the flow rate and mixing time while ensuring a certain flow rate. When the gas-liquid mixture flows through the channel, this width provides sufficient space for the gas and the liquid to fully interact and mix during the process of flowing through the first channel 11a, the second channel 11b, and the third channel 11c. The longer mixing time helps carbon dioxide dissolve more fully in the liquid, ensuring that the finally prepared bubble water has an appropriate carbon dioxide concentration and taste.

[0070] The narrow design of the transition channel makes the contact between the gas and the liquid closer when the gas-liquid passes through. During the process of the gas being compressed and fully contacting the liquid, its dissolution rate increases. According to Henry's law, at a certain temperature, the solubility of a gas in a liquid is proportional to the partial pressure of the gas. The narrow channel increases the relative partial pressure of the gas, thereby promoting the dissolution of carbon dioxide in the liquid and enhancing the carbonation efficiency of the bubble water. A width of 0.8 mm - 1.2 mm precisely regulates the flow rate and pressure of the gas-liquid mixture entering the dynamic turbulence chamber 12. When the gas-liquid passes through the narrow transition channel, the flow rate increases and the pressure also changes accordingly. This change in flow rate and pressure enables the gas-liquid to enter the dynamic turbulence chamber 12 in a state more suitable for stirring and mixing, improving the working efficiency of the dynamic turbulence chamber 12 and ensuring that the gas-liquid can be more fully mixed and carbonated in the dynamic turbulence chamber 12.

[0071] Furthermore, the tips of the first turbulence protrusion 13 and the second turbulence protrusion 14 are oppositely arranged; the distance between the two first turbulence protrusions 13 and the second turbulence protrusion 14 is in the range of 1.5 mm - 2.5 mm.

[0072] Specifically, the cross-sections of both the first spoiler protrusion 13 and the second spoiler protrusion 14 are triangular. The first spoiler protrusion 13 and the second spoiler protrusion 14 with their tips facing each other are like a pair of highly efficient cutters. When the gas-liquid mixture flows through, the tips of the protrusions can precisely divide the gas-liquid flow into fine streamlets. These streamlets intersect and collide with each other in the channel, greatly increasing the gas-liquid contact area. The setting of the protrusions with their tips facing each other enables the gas-liquid flow to move along a relatively streamlined path when passing through. Compared with other setting methods, it reduces the resistance caused by fluid separation and lowers the energy loss. The gas-liquid flows more smoothly in the channel, improving the operating efficiency of the carbonator 100 and reducing the energy consumption.

[0073] The distance between the first spoiler protrusion 13 and the second spoiler protrusion 14, that is, the distance between the two tips, is in the range of 1.5 mm - 2.5 mm, which causes a strong interaction between the gas and the liquid when passing through. In this narrow space, the gas-liquid flow has a high speed and a large pressure change, forming complex turbulences and vortices. These turbulences and vortices continuously stir the gas and the liquid, accelerating the diffusion of carbon dioxide in the liquid and significantly improving the carbonation efficiency of the sparkling water. The distance of 1.5 mm - 2.5 mm ensures the stable flow of the gas-liquid flow between the protrusions. It avoids the flow field disorder caused by too large or too small a distance. The stable flow state is conducive to continuous and efficient gas-liquid mixing, ensuring the long-term stable operation of the carbonator 100.

[0074] Furthermore, the distance between two adjacent first spoiler protrusions 13 is in the range of 2 mm - 6 mm.

[0075] Specifically, after the gas-liquid mixture flows through the first spoiler protrusion, its flow direction and speed change. The setting with an interval of 2 mm - 6 mm guides the changed gas-liquid flow to flow towards the second spoiler protrusion in an orderly manner. After being disturbed again by the second protrusion, the gas-liquid flow gradually converges in the subsequent channel. Different interval distances affect the convergence mode of the gas-liquid flow. A narrower interval makes the gas-liquid flow converge quickly, generating a high-intensity interaction; a wider interval allows the gas-liquid flow to converge slowly in a larger space, achieving a more thorough mixing. This orderly guidance and re-convergence process ensure the uniform mixing of the gas and the liquid across the entire cross-section of the channel, avoiding the problem of uneven local mixing and improving the stability of the quality of the sparkling water. The reasonable interval setting optimizes the flow field of the gas-liquid flow between the two spoiler protrusions. After being disturbed by the first protrusion, the gas-liquid flow can gradually adjust its flow state within the interval and flow towards the second protrusion in a more streamlined manner. Compared with the case of an unreasonable interval, it reduces the resistance caused by fluid separation and disorderly flow. The gas-liquid flows more smoothly in the channel, improving the operating efficiency of the carbonator 100 and reducing the energy consumption.

[0076] The interval range of 2mm - 6mm ensures that the gas-liquid flow can maintain a stable flow state between two adjacent turbulence protrusions. It avoids the problems of excessive flow velocity and large pressure fluctuations caused by too small an interval, which would lead to increased internal wear of the equipment; it also prevents the problems of insufficient gas-liquid mixing and unstable flow field caused by too large an interval. The stable flow state is conducive to continuous and efficient gas-liquid mixing, ensuring the long-term stable operation of the carbonator 100 and reducing the frequency and cost of equipment maintenance.

[0077] Furthermore, the shape of the dynamic turbulence chamber 12 is a circular cavity. The impeller 50 is located at the central position of the dynamic turbulence chamber 12, and a plurality of third turbulence protrusions 121 protrude from the circumferential side wall of the dynamic turbulence chamber 12 towards the impeller 50.

[0078] Specifically, the circular cavity shape of the dynamic turbulence chamber 12 helps to form a relatively uniform flow field. When the gas-liquid mixture enters the circular dynamic turbulence chamber 12, under the agitation of the impeller 50, the gas and liquid can be distributed and flow relatively uniformly in the circumferential direction. This uniform flow field distribution enables the gas and liquid to have sufficient mixing opportunities throughout the dynamic turbulence chamber 12, avoiding the problem of local insufficient mixing caused by uneven flow field and ensuring the consistency of carbon dioxide concentration and quality of the bubble water at different positions. The impeller 50 is located at the central position of the dynamic turbulence chamber 12 and can uniformly transmit the agitation force from the center to the surroundings. When the impeller 50 rotates, the centrifugal force and shear force generated can effectively drive the gas-liquid mixture to rotate and flow at high speed throughout the circular cavity. This all-round agitation effect enables the gas and liquid to come into full contact.

[0079] The plurality of third turbulence protrusions 121 protruding from the circumferential side wall of the dynamic turbulence chamber 12 towards the impeller 50 further enhance the agitation effect of the gas and liquid. When the gas-liquid mixture flows towards the circumferential side wall driven by the impeller 50, it will collide and rub against the third turbulence protrusions 121. These protrusions divide the gas-liquid flow into multiple small streamlets, changing the flow direction and velocity of the gas and liquid, and forming complex turbulence and vortices. These turbulence and vortices can continuously agitate the gas and liquid, making the carbon dioxide gas dissolve more fully in the water and improving the carbonation effect of the bubble water.

[0080] Furthermore, the impeller 50 includes a main body column 51 and a plurality of blades 52 wound around the outer periphery of the main body column 51. There is an interval between the blades 52 and the third turbulence protrusions 121, and the interval is in the range of 0.5mm - 0.9mm.

[0081] Specifically, the main body column 51 of the impeller 50 serves as the support structure for the blades 52, ensuring the stability of the blades 52 during high-speed rotation. It provides a solid connection foundation for the blades 52, enabling the blades 52 to be evenly distributed around the outer periphery of the main body column 51, thereby ensuring that the impeller 50 generates a uniform stirring force during rotation and driving the gas-liquid mixture to perform an efficient circular motion within the dynamic turbulence chamber 12. The multiple blades 52 wound around the outer periphery of the main body column 51 are the key components for realizing gas-liquid mixing. When the impeller 50 rotates, the blades 52 push the gas-liquid mixture, generating strong centrifugal force and shear force. This force can quickly disperse the gas-liquid mixture, break large bubbles into tiny bubbles, and increase the gas-liquid contact area. At the same time, the rotation of the blades 52 can also cause the gas-liquid mixture to form a complex flow field within the dynamic turbulence chamber 12, promoting the full mixing between gas and liquid and the dissolution of carbon dioxide.

[0082] The interval of 0.5 mm - 0.9 mm between the blade 52 and the third turbulence protrusion 121 enables the gas-liquid mixture to interact with the third turbulence protrusion 121 at an appropriate speed and state when being pushed by the blade 52 of the impeller 50 towards the peripheral sidewall. A narrower interval (close to 0.5 mm) can cause the gas-liquid mixture to be more strongly disturbed when approaching the third turbulence protrusion 121, the gas-liquid flow to be divided into finer pieces, forming stronger turbulence and vortices, and further enhancing the gas-liquid mixing effect; while a wider interval (close to 0.9 mm) gives the gas-liquid mixture a certain buffer space, enabling it to perform a certain degree of internal mixing before reaching the third turbulence protrusion 121 and then colliding with the protrusion part, generating mixing effects of different scales. The setting of this interval optimizes the gas-liquid disturbance and mixing process to varying degrees, improving the carbonation efficiency of the bubble water. The appropriate interval range avoids direct contact and friction between the blade 52 and the third turbulence protrusion 121, reducing mechanical interference and wear. During the high-speed rotation of the impeller 50, if the distance between the blade 52 and the third turbulence protrusion 121 is too close, collisions may occur, resulting in equipment damage and unstable operation. The interval of 0.5 mm - 0.9 mm ensures a sufficient safety distance between the two, extending the service life of the equipment, reducing the noise and vibration during equipment operation, and improving the reliability and stability of the equipment.

[0083] In summary, the structure of the impeller 50 and the interval design between the blade 52 and the third turbulence protrusion 121 cooperate with each other to jointly achieve efficient and stable gas-liquid mixing within the dynamic turbulence chamber 12, playing an important role in enhancing the performance of the carbonator 100 and the quality of the bubble water.

[0084] It should be noted that in this embodiment, the gas - mixing box body 10 includes a bottom shell 10a, a seal 10c and a cover plate 10b. The above - mentioned static turbulence channel 11 and dynamic turbulence chamber 12 are formed on the bottom shell 10a. The cover plate 10b is covered on the bottom shell 10a to enclose the static turbulence channel 11 and the dynamic turbulence chamber 12. The seal 10c is arranged at the connection position between the cover plate 10b and the bottom shell 10a to enhance the sealing performance between the two. The cover plate 10b and the bottom shell 10a can be fixedly connected by means of bolts.

[0085] Please refer to Figure 5 and Figure 6 As shown, the present invention also provides another carbonator 100, which includes a Venturi tube 60, a gas - mixing box body 10, a liquid inlet pipe 20, a liquid outlet pipe 40 and an impeller 50. The Venturi tube 60 is used for preliminarily mixing carbon dioxide and water. The gas - mixing box body 10 has a static turbulence channel 11 and a dynamic turbulence chamber 12 that are connected and communicate with each other. One end of the liquid inlet pipe 20 is connected to the output end of the Venturi tube 60, and the other end is connected to the front end of the static turbulence channel 11. The liquid outlet pipe 40 is connected to the rear end of the dynamic turbulence chamber 12. The impeller 50 is rotatably arranged in the dynamic turbulence chamber 12.

[0086] The static turbulence channel 11 has a left side surface 111 and a right side surface 112. A plurality of first turbulence protrusions protrude from the left side surface 111 towards the right side surface 112, and a plurality of second turbulence protrusions 14 protrude from the right side surface 112 towards the left side surface 111. Each first turbulence protrusion 13 and second turbulence protrusion 14 extends from the bottom wall of the static turbulence channel 11 to the top wall of the dynamic turbulence channel, and the plurality of first turbulence protrusions and second turbulence protrusions 14 are arranged at intervals along the extending direction of the static turbulence channel 11.

[0087] Through the combination of the Venturi atomization tube 70 and the gas - mixing box body 10 in this embodiment, multi - stage mixing of gas and liquid is achieved, from preliminary mixing to enhanced mixing and then to deep mixing, greatly improving the uniformity and sufficiency of gas - liquid mixing, enabling carbon dioxide to dissolve more fully in water, and preparing high - concentration and good - taste sparkling water. The entire carbonator 100 has a compact structure, and each component works together, occupying a small space, being convenient to be integrated into various sparkling water devices, and can be well adapted to both small desktop devices and large commercial devices, improving the space utilization rate of the device.

[0088] The Venturi atomization tube 70 is used for the preliminary mixing of gas and liquid. It has a main body 64 and an inlet section 61, a suction section 62, and an outlet section 63 connected to the main body 64. The main body 64 is provided with a contraction section 641, a throat section 642, and a diffusion section 643. The inlet section 61 is connected to the contraction section 641, and both ends of the diffusion section 643 are respectively connected to the throat section 642 and the outlet section 63. The main body 64 is also provided with an air cavity 644. The suction section 62 communicates with the throat section 642 through the air cavity 644. The contraction section 641 is located between the inlet section 61 and the throat section 642 and is arranged in a frustum of a cone shape. The diffusion section 643 is located between the throat section 642 and the outlet section 63 and is also arranged in a frustum of a cone shape.

[0089] One end of the inlet section 61 is connected to the large end of the contraction section 641. The small end of the contraction section 641 is correspondingly arranged at one end of the throat section 642. The other end of the throat section 642 is connected to the small end of the diffusion section 643. The large end of the diffusion section 643 is connected to the outlet section 63. The suction section 62 communicates with the throat section 642 through the air cavity 644. The air cavity 644 is formed in the main body 64 of the pipe body and is located on the outer periphery of the contraction section 641 and on one side of the throat section 642 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 61 and entering the contraction section 641, forming a negative pressure in the throat section 642, sucking in carbon dioxide through the air cavity 644, and mixing it with the high-speed water flow. The reasonable design of the contraction section 641, the throat section 642, and the diffusion section 643, as well as the surrounding arrangement of the air cavity 644, ensure the sufficiency and stability of gas-liquid mixing, improving the preparation efficiency and quality of bubble water. The contraction section 641 - throat section 642 - diffusion section 643 structure of the main body 64 forms a multi-stage velocity increase - pressure decrease - pressure increase flow field, enabling the liquid velocity to be significantly increased in the throat section 642, thereby increasing the gas-liquid contact area and further improving the preliminary mixing efficiency of gas and liquid.
