挡水板会大大减少水和二氧化碳的接触面积,降低混合效率
[0017] The newly designed bubble water generator features an upward-facing outlet on its inlet pipe. A carbon dioxide inlet pipe is positioned above the outlet, and a water-blocking element is installed at the outlet end of the inlet pipe. By precisely positioning the outlet of the inlet pipe directly below the water-blocking element, the water flow impacts the element, forming a uniformly dispersed liquid film or droplet cluster, significantly increasing the contact surface area between water and gas. The dispersed falling water creates a localized turbulence zone around the water-blocking element, extending the gas-liquid contact time and increasing the carbon dioxide dissolution efficiency by over 30%. When the high-speed flowing fluid passes through the water-blocking element, a negative pressure is created around it, bringing in more carbon dioxide to mix with the water. This increases the contact area between the water and the carbon dioxide in the carbonization tank, resulting in more thorough mixing.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage production equipment technology, specifically a sparkling water generator. Background Technology
[0002] Industry Development and Demand Background: With the popularization of the "sugar-free, low-calorie, and zero-additive" consumption concept, the global sparkling water market is expanding rapidly at a compound annual growth rate of over 12%. Sparkling water makers allow people to easily create their own favorite beverages, leading to a continuous increase in global sales of home sparkling water makers.
[0003] However, existing technologies, such as Chinese utility model patent CN202457927U, disclose a combination valve with an atomizing device for a carbonation tank of a soda water machine, including a valve body with a nozzle connected to it. The valve body is characterized in that a baffle plate is provided below the valve body, and the surface of the baffle plate is directly opposite the outlet of the nozzle. Patent CN206843049U discloses a tank assembly for a soda water machine. The tank assembly comprises: a cold water tank, including a tank body and a lid, the tank body having an upward-facing water cavity, the lid covering the opening of the water cavity, and the cold water tank having a pure water inlet and a cold water outlet communicating with the water cavity; a soda water tank, fixed to the cold water tank, with at least a portion extending into the water cavity within the cold water tank, the soda water tank having a cold water inlet, a soda water outlet, and an air inlet, the cold water inlet communicating with the cold water outlet; and an evaporator, at least partially disposed on the cold water tank. Patent CN202589297U discloses a carbonation tank for a soda water machine with an atomizing device, comprising a tank body with an upper opening, wherein a combination valve is provided at the opening of the tank body, the combination valve being connected to a nozzle and a water outlet pipe, characterized in that: a baffle plate is provided inside the tank body, the baffle plate dividing the interior of the tank body into an upper space for containing carbon dioxide gas and a lower space for containing water, an overflow channel being provided between the upper space and the lower space, and the surface of the baffle plate being directly opposite the water outlet of the nozzle. The nozzle of the aforementioned utility model patent is vertically downward. Water passes through the nozzle and forms a high-speed water column. After the water column hits the baffle plate, it forms upward-scattering water droplets. During the natural fall, the water droplets form many tiny water droplets and come into full contact with the carbon dioxide filled in the upper space. The water absorbs the carbon dioxide and completes the carbonization process, effectively extending the contact time between water and carbon dioxide. The contact area is large, and the carbonization effect is obvious. Due to the use of the nozzle, the water flow rate is large and the water injection time is short. The water column sprayed from the nozzle is atomized after hitting the baffle plate and effectively combines with carbon dioxide before falling onto the baffle plate and overflowing to the bottom. This effectively avoids the high-speed uncarbonized water directly impacting the carbonized water at the bottom, ensuring the carbonization effect of the water exiting from the bottom.
[0004] However, through research and practice, the applicant discovered that the existing technology has flaws. In the existing technology, the nozzle points vertically downwards, and the high-pressure water jet impacts the horizontal baffle to form an umbrella-shaped water curtain. The baffle occupies the cross-section of the tank, and the water curtain is only distributed near the tank wall, creating a cavity in the central area. The effective contact area for carbon dioxide is only 40%–50% of the theoretical value. The baffle significantly reduces the contact area between water and carbon dioxide, lowering mixing efficiency. Utility Model Content
[0005] In order to overcome the above-mentioned technical defects, this utility model provides a bubble water generating device.

[0008] Preferably, a detection component is also connected to the tank body for detecting the liquid level of the bubble water.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] The newly designed bubble water generator features an upward-facing outlet on its inlet pipe. A carbon dioxide inlet pipe is positioned above the outlet, and a water-blocking element is installed at the outlet end of the inlet pipe. By precisely positioning the outlet of the inlet pipe directly below the water-blocking element, the water flow impacts the element, forming a uniformly dispersed liquid film or droplet cluster, significantly increasing the contact surface area between water and gas. The dispersed falling water creates a localized turbulence zone around the water-blocking element, extending the gas-liquid contact time and increasing the carbon dioxide dissolution efficiency by over 30%. When the high-speed flowing fluid passes through the water-blocking element, a negative pressure is created around it, bringing in more carbon dioxide to mix with the water. This increases the contact area between the water and the carbon dioxide in the carbonization tank, resulting in more thorough mixing. Attached Figure Description

Detailed Implementation
[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Through research and practice, the applicant discovered that existing technology has defects. In existing technology, the nozzle points vertically downwards, and the high-pressure water jet impacts a horizontal baffle to form an umbrella-shaped water curtain. The baffle occupies the cross-section of the tank, and the water curtain is only distributed near the tank wall, creating a cavity in the central area. The effective contact area for carbon dioxide is only 40%–50% of the theoretical value. The baffle significantly reduces the contact area between water and carbon dioxide, lowering mixing efficiency.
[0026] To solve this problem, such as Figures 1-4 As shown, this utility model designs a sparkling water generating device, including a tank 1 for containing sparkling water. The tank 1 is connected to a water inlet pipe 2, an air inlet pipe 3, and a water baffle 4. The air outlet 31 of the air inlet pipe 3 is connected to the interior of the tank 1. The water baffle 4 is fixedly installed inside the tank 1 and is located at the air outlet 31 of the air inlet pipe 3. The water outlet 21 of the water inlet pipe 2 is located directly below the water baffle 4 and maintains a preset distance from the water baffle 4, so that the water flow from the water inlet pipe 2 is buffered by the water baffle 4 and dispersed and falls to the liquid surface inside the tank 1.
[0027] Understandably, in existing technologies, the baffle plate occupies the cross-section of the tank 1, resulting in a water curtain that is only distributed near the wall of the tank 1, forming a cavity in the central area, thus limiting the effective contact area of carbon dioxide. In this invention, however, the baffle 4 is located at the outlet 31 of the air inlet pipe 3, and the water flow from the water inlet pipe 2 is buffered and dispersed before falling. This structure allows the water flow to form a more uniform distribution within the tank 1, avoiding the cavity phenomenon in the central area, thereby significantly increasing the contact area between water and carbon dioxide and improving the dissolution efficiency of carbon dioxide. The water flow, after being buffered by the baffle 4, disperses and falls, forming finer droplets, columns, or atomized forms. These fine water streams provide more contact points when they come into contact with carbon dioxide, further improving the dissolution effect. By rationally designing the position of the baffle 4 and the water flow introduction method, a better flow path is formed within the tank 1, enhancing the mixing effect of water and carbon dioxide. The water-blocking component 4 buffers and disperses the water flow, allowing it to mix better with the gas inside the tank 1 during its descent. This avoids ineffective flow caused by the water directly impacting the bottom or walls of the tank 1, thus improving mixing efficiency. This not only reduces manufacturing costs but also facilitates installation and maintenance, improving the reliability and service life of the device. By optimizing the water-blocking component 4 and the water introduction method, the problems of small carbon dioxide contact area and low mixing efficiency in existing technologies are effectively solved.
[0028] In one embodiment, a grounding connection port 6 is provided on the outer surface of the tank 1, which simplifies the grounding operation. It eliminates the need to open the tank 1 or use additional adapters, thereby improving installation efficiency and reducing the risk of poor contact caused by multiple connections. At the same time, the exposed port facilitates daily inspection and maintenance, and allows for intuitive judgment of the grounding connection status, thereby enhancing the safety and reliability of use.
[0029] Furthermore, a detection component 7 is connected to the tank 1 for detecting the level of the sparkling water. In this embodiment, the detection component 7 is equipped with a sensor 71 that extends into the tank 1, enabling real-time monitoring of the sparkling water level within the tank 1 to ensure that the level remains within a set reasonable range. This helps avoid problems such as overflow or blockage of the inlet pipe 2 due to excessively high levels and idling due to excessively low levels, thus ensuring stable operation of the equipment. By precisely controlling the level, the outlet 21 of the air inlet pipe 3 and the water inlet pipe 2 can be kept in optimal working condition, further improving the generation efficiency and quality of the sparkling water. The detection component 7 enables automated control of the sparkling water generator. In one embodiment, when the level is lower than the set value, the system can automatically start the water inlet device to replenish water; when the level reaches the upper limit, the system can automatically stop water intake, achieving intelligent management. Automated operation reduces manual intervention, lowers the labor intensity of operators, and improves the reliability and safety of equipment operation. By controlling the liquid level, production interruptions or equipment failures caused by liquid level fluctuations can be avoided, ensuring continuous and stable operation of the equipment and further improving production efficiency.
[0030] Furthermore, a water outlet pipe 5 is provided at the bottom of the tank 1. The inlet end 51 of the water outlet pipe 5 is lower than the outlet end 31 of the air inlet pipe 3 and the outlet 21 of the water inlet pipe 2. Understandably, because the inlet end 51 of the water outlet pipe 5 is lower than the outlet end 31 of the air inlet pipe 3 and the outlet 21 of the water inlet pipe 2, the sparkling water is fully mixed and dissolved within the tank 1 before being discharged. The gas-liquid flow that has just completed its initial mixing is first intercepted and fully dispersed by the water-blocking component. The bubbles continue to dissolve as they rise, while the water that has reached the required carbonization level gradually sinks to the bottom of the tank. The low-positioned water outlet pipe 5 only discharges the fully carbonized liquid at the bottom with stable bubbles, completely preventing the gas-liquid mixture that has not yet fully reacted from being directly carried away, ensuring that the sparkling water taken out each time is evenly carbonized and has a consistent taste. At the same time, it suppresses the disturbance of the carbonized liquid at the bottom by the high-speed water flow, maintains stable pressure inside the tank, and extends the continuous dispensing capacity. This design ensures sufficient residence time for the sparkling water within tank 1, allowing carbon dioxide to fully dissolve and thus improving the quality of the sparkling water. Because the sparkling water undergoes multiple circulations and mixing within tank 1, the bottom portion is typically the most uniform and stable. This design ensures better stability and consistency of the discharged sparkling water, avoiding quality issues caused by uneven distribution. The outlet pipe 5 is located at the bottom of tank 1, allowing the sparkling water within tank 1 to be completely extracted, facilitating equipment maintenance and cleaning.
[0031] In one embodiment, the tank 1 is equipped with a water outlet pipe 5 extending from the top to the bottom without being connected to the bottom. The water is extruded using the internal pressure of the tank 1. Once internal pressure is established in the tank 1, the carbonized water is continuously forced into the suspended inlet end 51 of the water outlet pipe 5 and discharged upwards under the gas pressure, eliminating the need for any mechanical pumps or valves, resulting in a minimalist structure. As the liquid level gradually decreases, the inlet end 51 of the water outlet pipe 5 remains in the liquid phase until the liquid inside the tank is almost completely drained, achieving high utilization. Furthermore, the inlet end 51 is far from any trace impurities that may accumulate, ensuring clean water output. The suspended inlet end 51 avoids disturbance to the bottom liquid flow, preventing the carbonized water from being affected by new high-speed water jets or rising bubbles, maintaining a stable degree of carbonization and ensuring a consistent taste when continuously dispensed. The water outlet pipe 5 only penetrates the tank 1 at a single point at the top, with no openings at the bottom, reducing the risk of leakage and improving overall pressure resistance and service life.
[0032] Furthermore, the inlet pipe 2 is configured with a U-shaped structure, and the outlet 21 is higher than the inlet end 51. The inlet pipe 2 is connected to an external booster pump to increase the flow rate of the water flowing through the inlet pipe 2. The outlet 21 is equipped with a spraying device, which has micropores.
[0033] Understandably, the inlet pipe 2 adopts a U-shaped structure and is connected to an external booster pump, allowing the water flow to achieve higher velocity and pressure before entering the tank 1. In this embodiment, the spraying device is a nozzle 22. This design allows the water flow to impact the baffle 4 at a higher speed when passing through the nozzle 22, thereby generating a stronger impact force. The nozzle 22 is provided with micropores, which further disperse the water flow into fine droplets or columns as it passes through. This dispersion effect not only increases the contact area between the water flow and carbon dioxide but also makes the water flow more evenly distributed within the tank 1, preventing the water flow from concentrating and impacting the walls or bottom of the tank 1, thus improving the efficiency of bubble water generation. Sufficient contact between fine water droplets and carbon dioxide: The fine water droplets formed after the water flow passes through the microporous nozzle 22 can fully contact the carbon dioxide gas inside the tank 1. The fine water droplets have a larger surface area and more contact points with carbon dioxide, thus significantly improving the dissolution efficiency of carbon dioxide. The U-shaped structure and booster pump design ensure a uniform water distribution within the tank 1, avoiding a cavity in the central area and further increasing the contact area between water and carbon dioxide, thus improving the quality of the sparkling water. The U-shaped inlet pipe 2 guides the water flow into a stable path, reducing turbulence and energy loss upon entering the tank 1. This design allows the water to more efficiently impact the baffle 4, further enhancing the dispersion effect. Precise control of the water flow rate and pressure via the external booster pump allows for adjustment of the impact force according to actual needs, optimizing the sparkling water generation process and improving equipment operating efficiency. The micro-orifices on the nozzle 22 can be designed and replaced as needed, further optimizing the water dispersion effect. This design allows the equipment to adapt to different application scenarios, improving its flexibility and adaptability. The water dispersed by the micro-orifice nozzle 22 forms more uniform and delicate bubbles, resulting in a better taste. This design not only improves the quality of the sparkling water but also meets consumers' demand for high-quality sparkling water.
[0034] Furthermore, the water-blocking component 4 is provided with a support structure and a baffle 41, and the water-blocking component 4 is sleeved on the air outlet end 31 of the air inlet pipe 3; the diameter of the baffle 41 is larger than the opening diameter of the air outlet end 31. The baffle 41 is integrally formed or welded to the support structure. The water-blocking component 4 is provided with a plurality of through holes 42, through which gas flows into the tank body 1, so that the gas and water are fully mixed.
[0035] Understandably, the numerous through holes 42 on the baffle 4 allow gas to flow evenly into the tank 1 from multiple directions. This design prevents gas from concentrating in a single direction, thus reducing turbulence and uneven distribution within the tank 1, allowing for more thorough mixing of gas and water. The diameter of the baffle 41 is larger than the diameter of the outlet 31, further increasing the contact area between gas and water and improving mixing efficiency. After entering the tank 1 through the through holes 42 on the baffle 4, the gas can fully mix with the fine water stream dispersed by the nozzle 22, forming fine and uniform bubbles. This design makes the bubbles in the sparkling water more delicate and improves the taste. The design of the baffle 4 allows gas to be evenly distributed in the water flow within the tank 1, avoiding bubble aggregation and uneven distribution, thereby improving the stability and consistency of the sparkling water. The baffle 41 is integrally formed or welded to the support structure, giving the baffle 4 high structural strength and stability. This design ensures the stability of the baffle 4 under the impact of water and gas flow, reducing water flow abnormalities caused by structural loosening. The through holes 42 on the baffle 4 can be designed and adjusted according to actual needs, further optimizing gas distribution and mixing effects. This design allows the equipment to adapt to different production requirements, improving its flexibility and adaptability. The structural design of the baffle 4 makes it easy to install and disassemble, facilitating maintenance and replacement. This design not only reduces equipment maintenance costs but also improves operating efficiency. The design of the baffle 4 allows gas to mix fully with the water flow, reducing waste due to incomplete gas dissolution. This design ensures that every drop of bubble water meets optimal quality standards, further improving the equipment's economic efficiency. Through the optimized design of the baffle 4, bubbles in the bubble water are evenly distributed, avoiding waste due to bubble aggregation, further improving the equipment's resource utilization efficiency.
[0036] The principle of the bubble water generator described in this utility model is as follows:
[0037] The water inlet pipe adopts a U-shaped structure and connects to an external booster pump, allowing the water to achieve higher flow velocity and pressure before entering tank 1. This design enhances the impact force of the water flow, providing power for the subsequent mixing process. The outlet 21 of the water inlet pipe 2 is equipped with a nozzle 22, which has micropores. After passing through the micropores, the water flow is dispersed into fine droplets or columns, increasing the surface area of the water flow and allowing for more thorough contact between the water and gas. The outlet 31 of the air inlet pipe 3 is connected to the interior of tank 1, allowing gas to enter tank 1 through the air inlet pipe 3. A water baffle 4 is fixedly installed inside tank 1, located at the outlet 31 of the air inlet pipe 3. The water baffle 4 has a support structure and a baffle 41, the diameter of which is larger than the diameter of the outlet. The water baffle 4 has several through holes 42, through which gas is divided and flows evenly into tank 1. This allows gas to enter the water flow from multiple directions, further increasing the contact area between gas and water and improving mixing efficiency. After the water flow is pressurized by the booster pump, it becomes a high-pressure fluid that is jetted at high speed through the micro-holes on the nozzle 22 onto the water baffle 4 and sprayed in all directions. When the high-speed flowing fluid passes through the through-hole 42 on the water baffle 4, it creates a negative pressure around it, thereby bringing in more carbon dioxide to mix with the water. The contact area between the water and the carbon dioxide in the carbonization tank increases, resulting in more thorough mixing and a higher carbon dioxide concentration. Furthermore, after the water flow is sprayed out from the outlet 21 of the inlet pipe 2, it is dispersed into finer droplets by the water baffle 4. The design of the water baffle 4 not only buffers the impact of the water flow but also guides the water flow to fall evenly (spraying or atomizing) onto the liquid surface inside the tank 1. The support structure of the water baffle 4 and the design of the baffle 41 ensure that the water flow is evenly distributed inside the tank 1, preventing the water flow from concentrating and impacting the wall or bottom of the tank 1, thereby improving the mixing efficiency of the aerated water.
[0038] Other structures of the bubble water generator described in this embodiment are described in the prior art.

Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
