Description

Technical Field

[0001] This utility model relates to the field of beverage production equipment technology, specifically a sparkling water production device. 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 CN202589297U, disclose a carbonation tank for a soda water machine with an atomizing device, including a tank body with an upper opening. A combination valve is provided at the opening of the tank body, which is connected to a nozzle and a water outlet pipe. The characteristic feature is that a baffle plate is provided inside the tank body, which divides 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 is provided between the upper space and the lower space, and the surface of the baffle plate is 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] Through practical research, the applicant found that in existing technology, the water inlet pipe is directly connected to the nozzle, and the water pressure depends entirely on the external water supply system. The large pressure fluctuations result in unstable water column velocity, inconsistent atomization effect, and difficulty in guaranteeing carbonization efficiency. Although the water column can form water splashes after hitting the baffle, the water droplet size distribution is relatively coarse. Some large water droplets fall too quickly, and the contact time with carbon dioxide gas is still insufficient. Moreover, the carbon dioxide is affected by pressure, and more carbon dioxide cannot enter, affecting the final water quality. Utility Model Content

[0005] To overcome the technical defects mentioned above, where water jets can form splashes after impacting the baffle plate, but the droplet size distribution is relatively coarse, some large water droplets fall too quickly, resulting in insufficient contact time with carbon dioxide gas, and the carbon dioxide cannot enter due to pressure, this utility model provides a sparkling water production device.

[0006] To solve the above problems, this utility model is implemented according to the following technical solution: The present invention discloses a sparkling water production device, comprising a tank for containing sparkling water, the tank being connected to a jetting device and a water-blocking assembly; the jetting device includes a water inlet pipe and an air inlet pipe, the air inlet pipe being sleeved over the water inlet pipe, and the outlet of the water inlet pipe extending into the air inlet pipe, with an annular gap between the inner wall of the air inlet pipe and the outer wall of the water inlet pipe, when water flows through the outlet, a negative pressure chamber is formed at the annular gap, actively drawing in the gas in the air inlet pipe and mixing it with the water initially; the water-blocking assembly is fixed inside the tank and faces the output end of the jetting device, for receiving and secondary mixing of gas and liquid, extending the contact time between the bubbles and the water.

[0007] Preferably, the water-blocking assembly is disposed on the top of the tank.

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

[0009] Preferably, the detection component includes a liquid level sensor.

[0010] Preferably, a water outlet pipe is provided at the bottom of the tank, with the inlet end of the water outlet pipe being lower than the output end of the jet device, or the water outlet pipe is provided at the top of the tank and extends from the top to the bottom without being connected to the bottom.

[0011] Preferably, the water-blocking component has an L-shaped structure.

[0012] Preferably, a grounding connection port is provided on the outer surface of the tank.

[0013] Preferably, the tank body is a pressure-resistant and sealed structure, and the water outlet pipe squeezes out bubble water through the internal pressure of the tank body.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The jet jet device uses an annular gap formed by extending the water inlet pipe into the air inlet pipe, utilizing the Venturi effect to create a negative pressure chamber at the gap. When water flows through the outlet, even with fluctuations in external water supply pressure, the negative pressure chamber can still stably and actively draw in gas, forming a gas-liquid two-phase flow. This mixing method reduces the sensitivity of water pressure fluctuations to the water column velocity, ensuring the stability of bubble generation and particle size, thus solving the problem of inconsistent atomization effects and improving carbonation efficiency. The water-blocking component faces the output end of the jet device, and the high-speed gas-liquid mixed flow undergoes two fusions after impacting the water-blocking plate. This extends the gas-liquid contact time, achieving secondary fusion of bubbles and water. The jet jet device utilizes the Venturi tube effect to introduce negative pressure air intake in the contraction section: a carbon dioxide air inlet is opened in the contraction section of the Venturi tube, and the negative pressure generated when water flows through the Venturi tube automatically draws in carbon dioxide gas, causing the gas and liquid phases to mix initially in the tube, while simultaneously introducing more carbon dioxide gas into the tank, forming a gas-liquid two-phase mixed flow that produces a better atomization effect.

Detailed Implementation

[0016] 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.

[0017] Existing sparkling water machines have defects, such as water pressure fluctuating with the municipal pipe network, water column speed varying from fast to slow, unstable atomization effect, and large fluctuations in carbonization efficiency; after the water column hits the baffle, it can only form coarse-diameter water splashes, large water droplets fall too quickly, the gas-liquid contact time is short, carbonization is insufficient, and the final water quality is reduced.

[0018] To address the shortcomings of existing technologies, such as Figures 1-3 As shown, the sparkling water production device of this utility model includes a tank 1 for containing sparkling water. The tank 1 is connected to a jetting device 2 and a water-blocking assembly 6. The jetting device 2 includes a water inlet pipe 21 and an air inlet pipe 22. The air inlet pipe 22 is sleeved on the water inlet pipe 21, and the outlet 211 of the water inlet pipe 21 extends into the air inlet pipe 22. An annular gap is left between the inner wall of the air inlet pipe 22 and the outer wall of the water inlet pipe 21. When water flows through the outlet 211, a negative pressure chamber 23 is formed at the annular gap, which actively draws in the gas in the air inlet pipe 22 and mixes it with the water for the first time. The water-blocking assembly 6 is fixed inside the tank 1 and faces the output end 24 of the jetting device 2. It is used to receive and mix the gas and liquid a second time, thereby prolonging the contact time between the bubbles and the water.

[0019] Understandably, the water inlet pipe 21 is inserted into the air inlet pipe 22, forming an annular gap between them. Water flowing through this gap creates a negative pressure chamber 23, employing the Venturi negative pressure principle. According to Bernoulli's equation, when a fluid flows steadily in a pipe, the sum of its pressure energy, kinetic energy, and potential energy remains constant. In the Venturi tube, after the fluid passes through the throat (negative pressure chamber 23), it enters the diffuser section (output end 24). In the diffuser section, the pipe gradually expands, the flow velocity slows down, and kinetic energy is converted into static pressure energy, thus gradually restoring the pressure. However, due to the low-pressure effect at the throat, a local negative pressure region has been created. This negative pressure region attracts surrounding air or other fluids to balance the pressure difference. Carbon dioxide is actively drawn in, forming a gas-liquid two-phase flow. Because the negative pressure chamber 23 is insensitive to changes in water pressure, even with fluctuations in external water supply pressure, the amount and size of bubbles generated remain stable. The water-blocking component 6 is fixed inside the tank 1 and faces the output end 24 of the jet device 2. After the high-speed gas-liquid mixture impacts the water-blocking plate, a "double fusion" occurs: the first fusion occurs when coarse bubbles are sheared and refined at the moment of impact; the second fusion occurs when water droplets come into contact with rising carbon dioxide again during their fall, extending the gas-liquid contact time. The sensitivity to water pressure fluctuations is significantly reduced, and the atomization effect remains stable over a long period; the bubble particle size is refined and evenly distributed, and the carbon dioxide solubility is significantly improved; the double fusion and extended contact time result in a carbonization efficiency higher than existing technologies.

[0020] Furthermore, the water-blocking component 6 is disposed on the top of the tank body 1.

[0021] Understandably, such as Figure 2As shown, the water inlet pipe 21 is fitted inside the air inlet pipe 22. The high-speed water flow at the outlet 211 forms a negative pressure chamber 23 in the annular gap, actively drawing in gas and immediately mixing it with water for the first time. This eliminates the need for an additional power source, improving dissolved air efficiency. The water-blocking component 6, directly opposite the jet outlet, forces the mixed fluid to impact, generating intense turbulence that further breaks down and refines the bubbles. Simultaneously, it extends the bubble's upward path, increasing the gas-liquid contact time and significantly improving the carbon dioxide dissolution rate. The water-blocking component 6 can optionally be installed on the top of the tank 1, allowing for flexible selection based on space or process requirements to ensure consistent mixing. Both the jet and the baffle utilize fluid kinetic energy to complete the air intake and secondary mixing, eliminating the need for stirring or a pressure pump, thus reducing power consumption and maintenance costs.

[0022] Furthermore, a detection component 3 is connected to the tank 1 for detecting the level of the sparkling water. The detection component 3 includes a level sensor. In this embodiment, the detection component 3 is equipped with a sensor that extends into the tank 1, enabling real-time monitoring of the sparkling water level inside the tank 1 to ensure that the level is always maintained within a set reasonable range. This helps avoid problems such as overflow due to excessively high levels and equipment idling due to excessively low levels, thereby ensuring stable equipment operation. By precisely controlling the level, the output end 24 of the jet device 2 can always be in optimal working condition, further improving the generation efficiency and quality of sparkling water. The detection component 3 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 jet device 2 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 level, production interruptions or equipment failures caused by level fluctuations can be avoided, ensuring continuous and stable equipment operation and further improving production efficiency.

[0023] Furthermore, a water outlet pipe 5 is provided at the bottom of the tank body 1. The inlet end of the water outlet pipe 5 is lower than the output end 24 of the jet device 2, or the water outlet pipe 5 is provided at the top of the tank body 1 and extends from the top to the bottom, but is not connected to the bottom.

[0024] Understandably, in one embodiment, the inlet of the bottom water outlet pipe 5 is lower than the jet output end 24, forming a drop of low-level drainage and high-level air intake, so that the high-concentration bubble water that has completed secondary mixing is preferentially used, and the large bubbles that have not been fully dissolved continue to rise and circulate, thereby ensuring that the outflowing bubble water has a stable and fine air content.

[0025] In another embodiment, the top outlet pipe 5 extends downwards but does not touch the bottom, suspending the water inlet in the middle of the liquid layer, which avoids impurities that may be deposited and traps large air bubbles that have not been completely dissolved; at the same time, it uses static pressure difference to achieve gravity discharge, eliminating the need for additional pumping, simplifying the system and reducing energy consumption.

[0026] Both layout options can be freely selected based on the installation space of tank 1 and the routing of pipelines. Both can achieve an orderly process of first dissolving air and then discharging water without adding power components, further improving the efficiency and reliability of the whole machine.

[0027] Furthermore, a grounding connection port 4 is provided on the outer surface of the tank body 1. Providing a grounding connection port 4 on the outer surface of the tank body 11 simplifies the grounding operation, eliminating the need to open the tank body 11 or use additional adapters. This improves installation efficiency and reduces 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 safety and reliability.

[0028] Furthermore, the tank body 1 is a pressure-resistant and sealed structure, and the water outlet pipe 5 extrudes bubbled water through the internal pressure of the tank body 1. The tank body 1 is pressure-resistant and sealed as a whole, and the jetting and dissolving process is continuously pressurized within the closed cavity, with the carbon dioxide solubility increasing with the pressure. When water needs to be discharged, the pressure inside the tank itself can directly extrude high-concentration bubbled water from the water outlet pipe 5, without the need for a pump or valve to pressurize again. This eliminates moving parts, reduces noise and failure rate, and ensures stable output flow and persistent, fine bubbles. Example

[0029] like Figure 2 As shown, the jetting device 2 is located at the top of the tank 1, and the output end 24 of the jetting device 2 is positioned directly above the water-blocking component 6. The jetting device 2 forms the initial mixing, improving dissolved air efficiency. The water-blocking component 6, directly opposite the jet outlet, forces the mixed fluid to impact, generating intense turbulence. The shear force at the moment of impact further breaks the initial bubbles into microbubbles, significantly reducing the proportion of large water droplets and further refining the bubbles. Simultaneously, it extends the bubble's upward path, increasing the gas-liquid contact time, forming secondary mixing, and significantly improving the carbon dioxide dissolution rate. In this embodiment, the water-blocking component 6 has an L-shaped structure. The horizontal section of the L-shaped structure faces the jet outlet, forming an impact surface that instantly generates a large-area shear zone, rapidly breaking the initially mixed bubbles into uniform microbubbles. The vertical section extends downward, forcing the microbubbles to rise along a zigzag path, significantly extending the residence time and improving the carbon dioxide dissolution rate. The bent structure achieves both impact and deflection effects within a limited height, saving space in the tank 1, maintaining the compactness of the top jet arrangement, and reducing material usage. Example

[0030] like Figure 3As shown, the jetting device 2 is located at the top of the tank 1, and the output end 24 of the jetting device 2 extends to the bottom and is a certain distance from the bottom. The sparkling water undergoes a first mixing in the jetting device 2. The sparkling water that has completed the first mixing impacts the bottom of the tank 1 through the output end 24, causing the sparkling water that has completed the first mixing to form a second mixing with the sparkling water at the bottom of the tank 1. Due to the high-speed fluid mixing with the carbon dioxide at the bottom, a stirring effect is also achieved, which significantly improves the carbon dioxide dissolution rate. This makes the gas and liquid mixing more thorough and optimizes the taste of the sparkling water.

[0031] Other structures of the bubble water production device described in this embodiment are described in the prior art.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. 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.
