Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0047] Currently, the sales volume of high-end sparkling water in the market has been increasing year by year, and users' acceptance of 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 getting higher and higher. However, currently, automatic sparkling water machines in the market generally cannot meet users' pursuit of the quality of sparkling water. This is mainly because the technical solutions of the commonly used high-pressure carbonation tanks in the market result in insufficient concentration of the produced sparkling water, and the concentration of the sparkling water produced by the current sparkling water machines cannot be adjusted.

[0048] In view of this, the present invention proposes a sparkling water device 100.

[0049] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the sparkling water device 100 includes an outer cover 1, a refrigeration module 2, a water pump 3, a Venturi tube 5, and a flow-through carbonator 4; a receiving cavity 11 is formed inside the outer cover 1; the refrigeration module 2 is installed in the receiving cavity 11; the water pump 3 is installed beside the refrigeration module 2; the flow-through carbonator 4 is installed on one side of the refrigeration module 2. The flow-through carbonator 4 includes a housing, a turbulent flow channel is arranged inside the housing, a liquid inlet 42 communicating with the turbulent flow channel is opened on the outer side of the housing, the liquid inlet 42 communicates with the Venturi tube 5, and the turbulent flow channel is used to generate turbulent flow to increase the gas-liquid contact area; the gas tank 9 communicates with the air inlet 41, and a pressure regulating valve 71 is arranged between the gas tank 9 and the air inlet 41 to regulate the gas delivery volume of the gas tank 9.

[0050] In the prior art, bubble water preparation equipment typically relies on a high-pressure carbonation tank to achieve the mixing of gas and liquid. However, such devices have the problem of low gas dissolution efficiency, resulting in insufficient gas concentration in the final produced bubble water. In traditional equipment, the gas-liquid contact area is limited, and the gas input amount cannot be effectively controlled during the mixing process, making it difficult for users to adjust the bubble water concentration according to their needs.

[0051] To solve the above problems, the R & D team focused on improving the gas-liquid mixing efficiency and equipment integration. It was found that the static mixing method of traditional carbonation tanks cannot form sufficient gas-liquid contact interfaces. Through fluid mechanics analysis, it was found that the turbulent state can significantly improve the dissolution efficiency, and dynamically adjusting the gas input amount is the key to achieving concentration control. On this basis, it was proposed to decompose the gas-liquid mixing process into multi-stage processing, and break through the technical bottleneck by optimizing the flow channel structure and gas injection method.

[0052] Therefore, this application proposes a bubble water device 100, which includes a housing 1 forming a receiving cavity 11, a refrigeration module 2 installed in the receiving cavity 11, a water pump 3 disposed on the side, and an over-current carbonator 4 including a housing. The over-current carbonator 4 is internally provided with a turbulence channel, and an air inlet 41 and a liquid inlet 42 communicating with the channel are opened on the outside. The refrigeration module 2 is connected to the liquid inlet 42 through the water pump 3, and the gas tank 9 is connected to the air inlet 41 through a pipeline with a pressure regulating valve 71 to form a controllable gas-liquid mixing system.

[0053] Among them, the over-current carbonator 4 refers to a mixing device with an internal flow channel structure. Specifically, it can adopt a metal housing with spiral protrusions or staggered baffles on the inner wall to generate turbulence by changing the fluid movement trajectory. The turbulence channel refers to a fluid channel with an irregular cross-section. Specifically, it can adopt a corrugated pipe with a periodically changing cross-section width to force the fluid to generate vortex motion. The air inlet 41 refers to an interface connecting the gas source and the mixing chamber. Specifically, it can adopt a quick connector to connect the pipeline of the gas tank 9. The pressure regulating valve 71 refers to a device for controlling the gas flow rate. Specifically, it can adopt a proportional solenoid valve to adjust the opening degree through an electrical signal.

[0054] Specifically, after the water is cooled by the refrigeration module 2, it is pressurized by the water pump 3 and transported to the liquid inlet 42 of the over-current carbonator 4. The carbon dioxide gas released from the gas tank 9 is quantitatively supplied to the air inlet 41 through the pressure regulating valve 71. When the liquid and gas meet in the turbulence channel, the convex structure on the inner wall of the channel destroys the laminar flow state and forms intense turbulence. This turbulent state divides the gas into micron-sized bubbles, greatly increasing the gas-liquid contact area. The refrigeration module 2 continuously cools the circulating liquid to maintain the optimal dissolution temperature.

[0055] Compared with the prior art, traditional high-pressure carbonation tanks rely on static mixing and lack the function of gas flow regulation. This solution improves the gas dissolution efficiency by two orders of magnitude through the active generation of turbulence. Adopting a modular layout design, the flow-through carbonator 4 and the refrigeration module 2 are installed side by side, effectively reducing the equipment volume. The adjustable gas supply system breaks through the limitation of fixed concentration output, and users can precisely control the gas content of the bubble water through the pressure regulating valve 71.

[0056] Through the above technical solutions, this application achieves a significant improvement in gas dissolution efficiency and can prepare high-concentration bubble water at room temperature. The dynamic adjustment function meets the personalized needs of different users, and stable output can be achieved from low-concentration bubble water to high-concentration soda water. The compact structure design reduces the floor area of the equipment and is suitable for scenarios with limited space such as home kitchens. The coordinated operation of multiple modules ensures the continuous and stable carbonization process, overcoming the defects of intermittent operation of traditional equipment.

[0057] In one embodiment, please refer to Figure 1 and Figure 3 , the bubble water device 100 further includes an outlet module 6. The outlet module 6 includes an outlet 61 and a terminal flow stabilizer 62 provided upstream of the outlet 61. The terminal flow stabilizer 62 is used to reduce the flow rate of the outlet water.

[0058] Among them, the outlet 61 refers to the structure through which the liquid discharges from the inside of the device. Specifically, it can be implemented by a tubular or hole-shaped structure, and its position setting needs to cooperate with the terminal flow stabilizer 62 to achieve flow rate control.

[0059] Among them, the terminal flow stabilizer 62 refers to a flow regulation device located upstream of the outlet 61. Specifically, it can be implemented by a perforated plate, a damper or a converging-diverging flow channel. By changing the fluid flow path or increasing the flow resistance, the liquid flow rate is reduced, and the turbulence caused by the water flow impact is reduced, thereby improving the uniformity of the bubble water taste.

[0060] Specifically, during the preparation of bubble water, the water flow passes through the flow-through carbonator 4 and then enters the outlet 61 through the terminal flow stabilizer 62. The terminal flow stabilizer 62 gradually reduces the water flow speed before reaching the outlet 61 by restricting the flow channel cross-sectional area or increasing the flow resistance, avoiding gas-liquid separation or uneven bubble distribution caused by too fast flow rate. For example, when using a perforated plate, the water flow is dispersed into multiple small flow streams, and the flow rate is reduced when passing through the pores, while promoting the stable distribution of bubbles. Thus, the bubble water finally discharged from the outlet 61 has a more uniform bubble density and a more delicate taste.

[0061] Compared with the prior art, the conventional bubble water device 100 is usually not provided with a terminal flow stabilizing structure, resulting in a high water flow velocity when the water is discharged, and bubbles are easily broken or escaped, which affects the concentration and taste of the bubble water. This solution effectively suppresses flow velocity fluctuations and reduces bubble escape by introducing a terminal flow stabilizer 62, so that carbon dioxide and water are mixed more fully.

[0062] Through the above technical scheme, the present application can significantly improve the stability and taste uniformity of the sparkling water, solve the problem of insufficient bubble concentration caused by excessive flow rate in existing equipment, and avoid excessive foam generation or stratification caused by water flow impact, thereby meeting users' demand for high-quality sparkling water.

[0063] In one embodiment, see Figure 1 and Figure 3 An air flow cut-off valve 72 is also provided between the pressure regulating valve 71 and the gas tank 9 to control the opening or closing of the gas tank 9.

[0064] The present application further proposes that an air flow cut-off valve 72 is provided between the pressure regulating valve 71 and the gas tank 9 to control the opening or closing of the gas tank 9 .

[0065] Among them, the air flow shut-off valve 72 refers to a device used to cut off or conduct the gas passage between the gas tank 9 and the pressure regulating valve 71, which can be specifically implemented by a solenoid valve or a manual mechanical valve. It ensures the independence of the gas supply of the gas tank 9 by actively controlling the on-off state of the gas passage.

[0066] The pressure regulating valve 71 is a device for adjusting the gas output pressure, which can be implemented by a proportional valve or a pressure reducing valve 73. The pressure regulating valve 71 changes the gas flow rate by adjusting the valve body opening, thereby controlling the gas-liquid mixing ratio during the carbonization process.

[0067] Specifically, the gas flow stop valve 72 is installed in the gas path between the outlet of the gas tank 9 and the pressure regulating valve 71. When the equipment needs to stop supplying gas, the connection between the gas tank 9 and the downstream pipeline can be completely cut off by closing the valve. When the gas tank 9 is open, the gas flow stop valve 72 and the pressure regulating valve 71 work in conjunction. The former controls the opening and closing state of the gas passage, and the latter adjusts the gas output pressure and flow rate. The cooperation of the two can realize the hierarchical control of the gas supply of the gas tank 9.

[0068] Compared with the prior art, the traditional sparkling water machine only relies on a single pressure regulating valve 71 to control the gas flow, and cannot completely isolate the gas tank 9 when shutting down, resulting in the risk of gas residue or leakage. This solution separates the gas path opening and closing from the flow regulation function by adding an independent air flow stop valve 72, avoiding the sealing failure problem caused by the pressure regulating valve 71 being in a critical opening for a long time, and at the same time improving the operational safety during the maintenance of the gas tank 9.

[0069] Through the above technical solution, the present application solves the problem that the existing equipment cannot accurately control the on-off state of the gas circuit, realizes the rapid cut-off and stable regulation of the gas supply of the gas tank 9, avoids the decrease in carbonization efficiency caused by gas leakage, and at the same time reduces the safety risk caused by the pipeline residual pressure during the disassembly and maintenance of the gas tank 9.

[0070] In one embodiment, please refer to Figure 2 and Figure 4 , the bubble water device 100 further includes a base 12, the outer cover 1 is installed on the base 12, the refrigeration module 2 includes a cold water tank 21 and a compressor 22, the compressor 22 is installed on the base 12, the cold water tank 21 is installed on the upper side of the compressor 22, and the flow-through carbonizer 4 is fixedly connected to one side of the cold water tank 21.

[0071] The present application further proposes that the bubble water device 100 further includes a base 12, the outer cover 1 is installed on the base 12, the refrigeration module 2 includes a cold water tank 21 and a compressor 22, the compressor 22 is installed on the base 12, the cold water tank 21 is installed on the upper side of the compressor 22, and the flow-through carbonizer 4 is fixedly connected to one side of the cold water tank 21.

[0072] Among them, the base 12 refers to a support structure for carrying the outer cover 1 and internal components, and can be specifically made of a metal frame or high-strength plastic, and is fixedly connected to the outer cover 1 by bolts or buckles to ensure the stability of the whole machine.

[0073] The compressor 22 refers to the power component of the refrigeration system, and can be specifically a rotary or piston compressor 22. Installing it on the base 12 can reduce the center of gravity and reduce vibration transmission.

[0074] The cold water tank 21 refers to a container for storing low-temperature liquid, and can be specifically made of a double-layer stainless steel structure and filled with heat-insulating materials. Installing it above the compressor 22 can utilize gravity to achieve natural convection and reduce the energy consumption of the water pump 3.

[0075] The flow-through carbonizer 4 being fixedly connected to one side of the cold water tank 21 means that the two are rigidly connected by a flange or a clamp. Specifically, installation interfaces can be provided on the side wall of the cold water tank 21, and quick assembly can be achieved through positioning pins to ensure the coordinated operation of the carbonizer and the refrigeration module 2.

[0076] Specifically, the base 12 serves as the bearing foundation of the whole machine. The outer cover 1 is fixed on its surface by screws or buckles to form a closed accommodation cavity 11. The compressor 22 is arranged on the base 12, and the mechanical vibration during operation is reduced by shock pads. The cold water tank 21 is vertically installed on the top of the compressor 22, and the two are connected by pipes to achieve refrigerant circulation. The flow-through carbonator 4 is rigidly connected to the side wall of the cold water tank 21 through a fixing bracket, so that the liquid inlet 42 of the carbonator can be directly connected to the low-temperature liquid output by the cold water tank 21, reducing the pressure loss caused by pipeline bending. This layout optimizes the space utilization rate through the upper and lower stacked structure, and at the same time, the rigid connection method enhances the stability between components.

[0077] Compared with the prior art, the traditional bubble water device 100 usually arranges the compressor 22 and the cold water tank 21 horizontally side by side, resulting in an overly large lateral dimension of the device, and the vibration of the compressor 22 is easily transmitted to the carbonator, affecting the gas-liquid mixing effect. In this solution, the base 12 centrally bears the compressor 22, and the cold water tank 21 and the compressor 22 are arranged in layers in the vertical direction, which not only reduces the floor area of the device but also reduces the vibration interference through shock absorption design. In addition, the rigid connection between the flow-through carbonator 4 and the cold water tank 21 avoids the leakage risk that may occur in hose connection.

[0078] Through the above technical solution, the present application can effectively reduce the vibration noise during the operation of the device and improve the stability of the gas-liquid mixing process; by vertically arranging the compressor 22 and the cold water tank 21, the floor area of the device is reduced, meeting the user's demand for a small-sized device; at the same time, the rigid connection structure simplifies the pipeline design and reduces the energy loss during liquid transportation, thereby improving the efficiency of bubble water preparation.

[0079] In one embodiment, please refer to Figure 2 and Figure 4 , an installation bracket 13 is installed on the base 12, an installation space 14 is formed between the installation bracket 13 and the base 12, the compressor 22 is located in the installation space 14, the cold water tank 21 is installed on the upper side of the installation bracket, and the water pump 3 is fixedly connected to one side of the installation bracket.

[0080] The present application further proposes that an installation bracket 13 is installed on the base 12, an installation space 14 is formed between the installation bracket 13 and the base 12, the compressor 22 is located in the installation space 14, the cold water tank 21 is installed on the upper side of the installation bracket 13, and the water pump 3 is fixedly connected to one side of the installation bracket 13.

[0081] Among them, the mounting bracket 13 refers to a support structure fixed on the base 12, which can be specifically implemented by a metal frame or a high-strength plastic bracket. Its function is to provide a stable mounting position for the cold water tank 21 and the water pump 3, and at the same time form a mounting space 14 to accommodate the compressor 22. The mounting space 14 refers to the area enclosed by the base 12 and the mounting bracket 13, which can be specifically implemented by the gap area between the bottom of the bracket and the base 12. Its function is to centrally arrange the compressor 22 at the lower part of the equipment to avoid occupying the mounting areas of other functional components. The compressor 22 being located within the mounting space 14 means that the entire compressor 22 is restricted within the area between the base 12 and the mounting bracket 13, which can be specifically achieved by bolt fixation or snap connection structures. Its function is to reduce the overall volume of the equipment through a compact layout. The cold water tank 21 being installed on the upper side of the mounting bracket 13 means that the cold water tank 21 is arranged on the supporting plane at the top of the mounting bracket 13, which can be specifically achieved by using a slide rail fit or a positioning pin for fixation. Its function is to form an upper and lower layered structure between the cold water tank 21 and the compressor 22 to optimize the space utilization rate. The water pump 3 being fixedly connected to one side of the mounting bracket 13 means that the water pump 3 is fixed on the lateral extension part of the mounting bracket 13, which can be specifically achieved by a clamping piece or a mounting plate. Its function is to keep the water pump 3 in a short-distance connection with the cold water tank 21 to reduce the complexity of the pipeline.

[0082] Specifically, the mounting bracket 13 is fixed on the upper surface of the base 12, and a closed space for accommodating the compressor 22 is formed between its bottom and the base 12. The compressor 22 is fixed on the surface of the base 12 by bolts. A horizontal support plate is provided at the top of the mounting bracket 13, and the bottom of the cold water tank 21 is embedded in the support plate through a positioning groove to achieve vertical direction limitation. A cantilever structure extends outward from the side wall of the mounting bracket 13, and the housing of the water pump 3 is fixed on the outer surface of the cantilever structure by a buckle. Thus, the compressor 22 is hidden in the space between the base 12 and the bracket, and the cold water tank 21 and the water pump 3 are respectively arranged at the top and side of the bracket, forming an overall three-dimensional layered layout.

[0083] Compared with the prior art, in the traditional bubble water machine, the compressor 22 is usually separately arranged outside the bottom of the equipment, resulting in an increase in the overall lateral size of the machine, and an additional connection bracket is required between the cold water tank 21 and the water pump 3. In this solution, the compressor 22 is built into the base 12 area through the mounting bracket 13, and at the same time, the cold water tank 21 and the water pump 3 are integrated on the bracket, effectively reducing the floor area of the equipment and simplifying the installation structure.

[0084] Through the above technical solution, this application can optimize the internal space layout of the bubble water machine. On the premise of ensuring the stable operation of the refrigeration module 2 and the water pump 3, it can significantly reduce the overall volume of the machine, while reducing the complexity of pipeline connection, improving the equipment assembly efficiency and structural reliability.

[0085] In one embodiment, please refer to Figure 3, the gas cylinder 9 includes a self-made gas cylinder 91 and a special-purpose gas cylinder 92. Both the self-made gas cylinder 91 and the special-purpose gas cylinder 92 are connected to the air inlet 41 through an air circuit board 74. Pressure reducing valves 73 are provided at the outlet ends of the self-made gas cylinder 91 and the special-purpose gas cylinder 92.

[0086] Among them, the self-made gas cylinder 91 refers to a gas storage container that can be refilled with carbon dioxide repeatedly. Specifically, it can be realized by using a metal tank body with a detachable connection interface, which is used to provide users with the flexibility to independently replenish the gas source. The special-purpose gas cylinder 92 refers to a gas storage container pre-filled with carbon dioxide once. Specifically, it can be realized by using a standardized sealed gas cylinder, which is convenient for quick replacement and requires no maintenance. The air circuit board 74 refers to a connecting component integrating gas passages. Specifically, it can be realized by using a metal or plastic substrate with multiple interfaces, which is used to centrally manage the air flow transmission paths of different gas cylinders 9. The pressure reducing valve 73 refers to a control device for regulating the gas output pressure. Specifically, it can be realized by using a spring-type or diaphragm-type pressure regulating structure, which is used to adjust the high-pressure gas in the gas cylinder 9 into a stable low-pressure air flow suitable for the carbonization process. And a pressure gauge 75 is provided at one end of the air circuit board 74 to test the pressure in the gas cylinder 9.

[0087] Specifically, the self-made gas cylinder 91 and the special-purpose gas cylinder 92 are connected in parallel to the air inlet 41 through the air circuit board 74. During operation, a single gas cylinder 9 or both gas cylinders 9 can be selected according to requirements. When the user needs high-concentration sparkling water, the self-made gas cylinder 91 can be opened and the gas delivery volume can be increased through its pressure reducing valve 73; when quick use is required, the special-purpose gas cylinder 92 can be selected and a stable air flow can be maintained through its pressure reducing valve 73. The air circuit board 74 combines the two air flows and then transports them to the air inlet 41 of the overcurrent carbonizer 4, avoiding the problem of complex pipelines caused by independent connection of multiple gas cylinders 9. The pressure reducing valve 73 of the self-made gas cylinder 91 can be set as an adjustable structure, allowing the user to manually adjust the output pressure according to the taste requirements, while the pressure reducing valve 73 of the special-purpose gas cylinder 92 can be preset with a fixed pressure value to simplify the operation.

[0088] Compared with the prior art, the existing sparkling water equipment 100 usually only supports a single type of gas cylinder 9 and lacks a pressure regulation function, resulting in a fixed bubble concentration and inability to adapt to different usage scenarios. This solution realizes the dual adjustability of gas source selection and output pressure through the dual-gas cylinder 9 compatibility design and independent pressure reducing valve 73 control. At the same time, the integrated layout of the air circuit board 74 reduces the length of external pipelines, which is beneficial to the miniaturization of the whole machine.

[0089] Through the above technical solutions, this application solves the problems that the traditional sparkling water machine cannot flexibly adjust the bubble concentration and has poor compatibility with the gas cylinder 9. Users can freely select the type of gas cylinder 9 according to actual needs and accurately control the gas input volume, so as to obtain a differentiated sparkling water taste. At the same time, the air circuit integrated design reduces the equipment complexity and saves internal space.

[0090] In one embodiment, refer to Figure 7 , a raised portion 15 is formed by the outer cover 1 bulging, and a gas tank placement position 16 is formed between the raised portion 15 and the water pump 3, and the gas tank 9 is arranged at the gas tank placement position 16; or the gas tank 9 is arranged outside the outer cover 1 and is connected to the gas circuit board 74 through a hose.

[0091] Among them, the outer cover 1 bulging to form the raised portion 15 means that a local protrusion is formed on the surface of the outer cover 1 to form a specific shape, which can be specifically realized by injection molding or sheet metal stamping process. This structure can optimize the internal space layout by using the shape of the outer cover 1 itself. The gas tank placement position 16 refers to the accommodating area formed by the gap between the raised portion 15 and the water pump 3, which can be specifically realized by adjusting the relative relationship between the contour of the outer cover 1 and the installation position of the water pump 3. This design enables the gas tank 9 to be embedded in a specific area inside the device to save external space. The hose connecting the gas circuit board 74 means that a flexible pipeline is used to connect the gas tank 9 and the gas circuit board 74, which can be specifically realized by using a food-grade silicone tube or a rubber tube. The bending characteristic of the hose allows the gas circuit to be connected when the gas tank 9 is placed outside.

[0092] Specifically, when the gas tank 9 needs to be installed inside, the gas tank 9 is fixed by the space formed between the raised portion 15 of the outer cover 1 and the water pump 3. At this time, the overall device presents a compact form, avoiding additional occupation of the tabletop space. When the user needs to replace the gas tank 9 or use a large-capacity gas tank 9, the gas tank 9 can be moved to the outside of the outer cover 1 and connected to the gas circuit board 74 through a hose. At this time, the length of the hose can be set to 50 - 100 cm to adapt to different placement positions. The two installation methods realize the flexible switching of the position of the gas tank 9 through structural optimization, which not only meets the daily use requirements of small-volume devices but also is compatible with the expansion scenario of large-capacity gas tanks 9.

[0093] Compared with the prior art, the traditional bubble water device 100 usually fixes the gas tank 9 inside the device or completely outside. The built-in solution results in an overly large device volume and limited capacity of the gas tank 9, while the external solution requires a separate configuration of a bracket and there is a risk of pipeline loosening. This solution forms an internal space through the raised portion 15 of the outer cover 1 and at the same time allows the gas tank 9 to be connected through a standardized hose when placed outside, expanding the flexibility of the gas tank 9 layout while maintaining the compactness of the device.

[0094] Through the above technical solution, this application solves the problems of overly large volume or inconvenient use caused by the single installation method of the gas tank 9 in traditional devices. It can adapt to the space limitation requirements in different scenarios while ensuring the function of adjusting the concentration of bubble water, and improves the user operation convenience.

[0095] In one embodiment, refer to Figures 1 to 3, the sparkling water device 100 further includes a water purification module 8, the water purification module 8 is arranged on the inner wall of the outer cover 1, and the water pump 3 is located between the water purification module 8 and the refrigeration module 2.

[0096] Among them, the water purification module 8 refers to a functional unit for filtering impurities in water. Specifically, it can be implemented by a filtering component including an activated carbon filter element or a reverse osmosis membrane. Its function is to improve the purity of the water quality and avoid impurities interfering with the bubble generation process.

[0097] Among them, the inner wall of the outer cover 1 refers to the side area inside the device shell that contacts the accommodation cavity 11. Specifically, it can be formed by injection molding to form a fixed card slot or an installation bracket 13. Its function is to save internal space and make the water purification module 8 and the refrigeration module 2 form a compact layout.

[0098] Among them, the water pump 3 being located between the water purification module 8 and the refrigeration module 2 means that the installation position of the water pump 3 is between the water outlet end of the water purification module 8 and the water inlet end of the refrigeration module 2. Specifically, it can be realized by pipeline series connection or flange connection. Its function is to optimize the water flow path and reduce the water pressure loss.

[0099] Specifically, the water purification module 8 is installed on the inner wall of the outer cover 1 through a fixing structure. For example, by using a snap or screw connection method, the water purification module 8 and the refrigeration module 2 form an adjacent layout up and down or left and right. The water pump 3 is arranged in the middle area between the water purification module 8 and the refrigeration module 2, receives the water treated by the water purification module 8 through the water inlet pipe, and transports the water to the cold water tank 21 of the refrigeration module 2 through the water outlet pipe. This layout enables the water flow to directly enter the refrigeration link after filtration, avoiding temperature fluctuations or secondary pollution caused by long-distance transportation, and at the same time reducing the resistance caused by pipeline bending.

[0100] Compared with the prior art, the traditional sparkling water device 100 usually sets the water purification module 8 independently outside or separates it from the refrigeration module 2, resulting in an increase in the volume of the device and a complex water flow path. This solution integrates the water purification module 8 on the inner wall of the outer cover 1 and combines the central arrangement of the water pump 3, which not only maintains the compactness of the whole machine but also shortens the water flow path, thereby improving the refrigeration efficiency and water quality stability.

[0101] Through the above technical solution, the present application can effectively solve the problem that the concentration of sparkling water is reduced due to the interference of water quality impurities. At the same time, the overall volume of the device is reduced through modular layout, meeting the dual requirements of users for taste and space occupancy rate.

[0102] The present invention also proposes a sparkling water device 100, please refer to Figures 6 to 10, the sparkling water device 100 includes a housing 1, a refrigeration module 2, a water pump 3, a Venturi tube 5, and a flow-through carbonator 4; a receiving cavity 11 is formed inside the housing 1; the refrigeration module 2 is installed in the receiving cavity 11; the water pump 3 is installed beside the refrigeration module 2; the Venturi tube 5 includes a tube portion 51 and an air inlet pipe 52 connected to the outer periphery of the tube portion 51, a flow-through pipeline 53 is provided inside the tube portion 51, the flow-through pipeline 53 includes an inlet section 531, a contraction section 532, a throat section 533, a diffusion section 534, and an outlet section 535 that are connected in sequence, and the air inlet pipe 52 communicates with the inlet of the throat section 533; the flow-through carbonator 4 is installed on one side of the refrigeration module 2, the flow-through carbonator 4 includes a housing, a turbulent flow channel is provided inside the housing, a liquid inlet 42 communicating with the turbulent flow channel is provided on the outer side of the housing, the liquid inlet 42 communicates with the Venturi tube 5, and the turbulent flow channel is used to generate turbulent flow to increase the gas-liquid contact area; the gas tank 9 communicates with the air inlet 41, and a pressure regulating valve 71 is provided between the gas tank 9 and the air inlet 41 to regulate the gas output of the gas tank 9.

[0103] Compared with the previous technical solution, in order to further improve the mixing effect of the flow-through carbonator in this embodiment, a Venturi tube 5 is also provided upstream of the flow-through carbonator 100 for initially mixing gas and fluid. The Venturi tube 5 includes a tube portion 51 and an air inlet pipe 52. Carbon dioxide enters the flow-through pipeline 53 from the air inlet pipe 52 of the Venturi tube 5, and water flows into the flow-through pipeline 53 from the inlet section 531. The two are mixed at the end of the inlet section 531 or the front end of the second contraction section 532 to form sparkling water. The mixed sparkling water flows through the second throat section 533 at an accelerated speed and flows out at a decelerated speed through the second diffusion section 534, and then flows into the flow-through carbonator 100 through the outlet section 535 for further filtration.

[0104] The Venturi tube 5 can be injection-molded from food-grade POM plastic and has good wear resistance and corrosion resistance. The Venturi tube 5 is used to mix gas and liquid. The CO2 gas in the CO2 gas cylinder will flow into the Venturi tube 5 through the air inlet end, and the water in the water storage tank will flow into the Venturi tube 5 through the water inlet end. Under the action of the Venturi tube 5, the CO2 gas is inhaled into the water and mixed and dissolved by using the Venturi effect, and finally the sparkling water flows out through the outlet section 535 of the Venturi tube 5. The tube portion 51 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 provided for easy production and processing.

[0105] Therefore, the present application proposes a sparkling water device 100, which includes a housing 1 forming an accommodation chamber 11, a refrigeration module 2 installed in the accommodation chamber 11, a water pump 3 disposed beside it, and an overcurrent carbonator 4 including a housing. A turbulence channel is provided inside the overcurrent carbonator 4, and an air inlet 41 and a liquid inlet 42 for connecting a communication channel are opened on the outside. The refrigeration module 2 is connected to the liquid inlet 42 through the water pump 3, and the gas tank 9 is connected to the air inlet 41 through a pipeline with a pressure regulating valve 71 to form a controllable gas-liquid mixing system.

[0106] Among them, the overcurrent carbonator 4 refers to a mixing device with an internal flow channel structure. Specifically, a metal housing with spiral protrusions or staggered baffles can be used on the inner wall to generate turbulence by changing the fluid movement trajectory. The turbulence channel refers to a fluid channel with an irregular cross-section. Specifically, a corrugated pipe with a periodically changing cross-section width can be used to force the fluid to generate vortex motion. The air inlet 41 refers to an interface connecting the gas source and the mixing chamber. Specifically, a quick connector can be used to connect the pipeline of the gas tank 9. The pressure regulating valve 71 refers to a device for controlling the gas flow rate. Specifically, a proportional solenoid valve can be used to adjust the opening degree through an electrical signal.

[0107] Specifically, after the water is cooled by the refrigeration module 2, it is pressurized by the water pump 3 and transported to the liquid inlet 42 of the overcurrent carbonator 4. The carbon dioxide gas released from the gas tank 9 is quantitatively supplied to the air inlet 41 through the pressure regulating valve 71. When the liquid and the gas meet in the turbulence channel, the convex structure on the inner wall of the channel destroys the laminar flow state and forms intense turbulence. This turbulent state divides the gas into micron-sized bubbles, greatly increasing the gas-liquid contact area. The mixed gas-liquid two-phase flows through the expansion section 534, decelerates and then outputs to complete the carbonization process. The refrigeration module 2 continuously cools the circulating liquid to maintain the optimal dissolution temperature.

[0108] Compared with the prior art, the traditional high-pressure carbonation tank relies on static mixing and lacks the gas flow rate adjustment function. By actively generating turbulence in this solution, the gas dissolution efficiency is increased by two orders of magnitude. Using a modular layout design, the overcurrent carbonator 4 and the refrigeration module 2 are installed side by side, effectively compressing the volume of the device. The adjustable gas supply system breaks through the limitation of fixed concentration output, and users can precisely control the gas content of the sparkling water through the pressure regulating valve 71.

[0109] Through the above technical solutions, the present application realizes a significant improvement in gas dissolution efficiency and can prepare high-concentration sparkling water under normal temperature conditions. The dynamic adjustment function meets the personalized needs of different users, and can stably output from low-concentration sparkling water to high-concentration soda water. The compact structure design reduces the floor area of the device and is suitable for scenarios with limited space such as home kitchens. The coordinated work of multiple modules ensures the continuous and stable carbonization process, overcoming the defect of intermittent operation of traditional devices.

[0110] 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.
