Description

Technical Field

[0001] This application relates to the field of micro-nano bubble water technology, and more particularly to a micro-nano bubble water device. Background Technology

[0002] Micro-nano bubble water is widely used in the bathing industry due to its delicate texture and excellent cleaning effect. In existing technologies, the generation of bubble water mainly relies on the gas-liquid mixing structure within the dissolved air tank, but this has the following limitations:

[0003] Traditional dissolved air tanks require multiple functional ports (such as air inlets, water inlets, and water outlets), which need to be assembled by welding multiple metal components. Due to the inherent limitations of welding processes, the addition of multiple functional ports increases the number of welding points, which in turn increases the number of sealing points. This design significantly increases the risk of water and air leakage during use, affecting the reliability and service life of the equipment. Utility Model Content

[0004] This application provides a micro / nano bubble water device to solve the technical problem in the prior art where the dissolved air tank has many functional ports, resulting in a large number of welding and sealing points, and a high risk of water and air leakage.

[0005] In a first aspect, this application provides a micro / nano bubble water device, including a gas-liquid integrated module and a gas dissolving tank;

[0006] The gas-liquid integrated module is a one-piece molded structure, which includes a water passage, a gas passage, and a mixing outlet. The water passage is connected to the gas passage, and the mixing outlet is located at the confluence of the water passage and the gas passage, and is used to output the gas-liquid mixed fluid.

[0007] The dissolved gas tank has an inlet and an outlet. The inlet is connected to the mixing outlet, and the outlet is connected to the water supply end.

[0008] In one possible implementation, a water pressure regulating element is provided between the inlet end of the water passage and the confluence to regulate the pressure of the water passage.

[0009] In one possible implementation, the water pressure regulator is a pressure reducing valve, so that the water pressure in the water passage is less than the air pressure in the air passage.

[0010] In one possible implementation, the water pressure regulator is a shut-off valve to close the water passage.

[0011] In one possible implementation, the water pressure regulator is a venturi tube, the venturi tube having a constriction section, and the air passage is connected to the constriction section.

[0012] In one possible implementation, the gas passage is provided with a one-way valve, the one-way valve opening direction being towards the confluence.

[0013] In one possible implementation, a supplementary air pump is provided between the one-way valve and the inlet end of the air passage.

[0014] In one possible implementation, the water passage is opposite to the air passage.

[0015] Secondly, this application provides a water heater, including a water inlet, a water outlet, and the aforementioned micro-nano bubble water device, wherein the water inlet is connected to an external water source, and the water outlet is connected to the water passage.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art:

[0017] This application provides a micro / nano bubble water device, comprising a gas-liquid integrated module and a dissolved gas tank. Water enters the water passage of the gas-liquid integrated module, and gas enters the gas passage. Since the water and gas passages are connected, water and gas meet at their confluence (mixing outlet). Depending on the operating state, the mixing outlet can output gas, liquid, or a gas-liquid mixture. The inlet of the dissolved gas tank is connected to the mixing outlet. Gas, liquid, or a gas-liquid mixture enters the dissolved gas tank from the mixing outlet. Inside the dissolved gas tank, gas continuously dissolves into the liquid, forming a gas-rich solution. With further changes in pressure and other conditions, the gas in the solution precipitates out in the form of micro / nano-sized bubbles, ultimately forming uniform micro / nano bubble water within the dissolved gas tank, which is then output from the outlet of the dissolved gas tank for use by the water user.

[0018] The gas-liquid integrated module of this application adopts an integrated molding structure. Compared with the traditional dissolved gas tank design that requires welding multiple functional ports, it reduces the number of welding points and sealing points, thereby significantly reducing the risk of water and gas leakage during the use of the dissolved gas tank and improving the reliability and service life of the equipment.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

Therefore, the example term "below" can include both upper and lower orientations.

[0036] To address the technical problem that existing dissolved air tanks have many functional ports, resulting in a large number of welding and sealing points and a high risk of water and air leakage, this application provides a micro-nano bubble water device.

[0037] Figures 1 to 5 A micro / nano bubble water device 100 provided in this application embodiment includes a gas-liquid integrated module 1 and a dissolved gas tank 2;

[0038] The gas-liquid integrated module 1 is a one-piece molded structure, which includes a water passage 101, a gas passage 102 and a mixing outlet 103. The water passage 101 is connected to the gas passage 102, and the mixing outlet 103 is located at the confluence 104 of the water passage 101 and the gas passage 102, and is used to output gas, liquid or gas-liquid mixture.

[0039] The dissolved gas tank 2 is provided with an inlet 201 and an outlet 202. The inlet 201 is connected to the mixing outlet 103, and the outlet 202 is connected to the water supply end.

[0040] In the above technical solution, the water passage 101 is used to transport water, and the gas passage 102 is used to transport gas. Water and gas enter the water passage 101 and the gas passage 102 respectively from their respective sources. Since the water passage and the gas passage are interconnected, the gas and liquid gradually approach each other during the flow process, and finally come into contact and mix at their confluence (i.e., the mixing outlet). Depending on different operating conditions, the mixing outlet can output gas, liquid, or a gas-liquid mixture.

[0041] The dissolved gas tank 2 has an inlet 201 and an outlet 202. The inlet 201 is connected to the mixing outlet 103 of the gas-liquid integration module 1. Gas, liquid, or a gas-liquid mixture output from the mixing outlet 103 directly enters the inlet 201 of the dissolved gas tank 2. After entering the dissolved gas tank 2, the gas continuously dissolves into the liquid, forming a gas-rich solution. With further changes in pressure and other conditions, the gas in the solution precipitates out in the form of micro-nano-sized bubbles, ultimately forming uniform micro-nano bubble water within the dissolved gas tank 2. This water is then output from the outlet 202 of the dissolved gas tank 2 for use by water-using devices (such as shower heads, cleaning equipment, etc.).

[0042] Traditional dissolved air tanks have multiple functional ports (air inlet, water inlet, water outlet, etc.), which are usually assembled by welding multiple metal parts. The welding process results in numerous welding points and sealing points, greatly increasing the risk of water and air leakage. In contrast, the gas-liquid integrated module 1 in this application is a one-piece molded structure, which greatly reduces the number of welding points and sealing points, significantly reducing the possibility of water and air leakage in the dissolved air tank 2 during use, and improving the reliability and stability of the equipment.

[0043] Furthermore, the reduced sealing risk minimizes internal corrosion and component damage caused by water and air leaks, thereby extending the lifespan of the entire micro-nano bubble water device and lowering user equipment replacement and maintenance costs. Additionally, the gas-liquid integrated module 1 of this application is a one-piece molded structure. During use, it can be integrally molded using engineering plastics or metal materials through injection molding, die casting, or 3D printing processes, reducing welding or splicing structures and improving sealing.

[0044] Meanwhile, compared to the traditional dissolved air tank 2 which designs the water and air paths separately, this application achieves miniaturization of the micro-nano bubble water device by integrating the water and air paths into a single channel using the gas-liquid integration module 1.

[0045] Please refer to Figure 2In one possible implementation, a water pressure regulator 105 is provided between the inlet end of the water passage 101 and the confluence 104 to regulate the pressure of the water passage 101. In the water passage 101, water enters from the inlet end and flows towards the confluence 104 of the water passage 101 and the air passage 102. The water pressure regulator 105 is installed between the inlet end of the water passage 101 and the confluence 104. When water passes through the water pressure regulator 105, the water pressure regulator 105 applies resistance to the water or changes the water flow state through its specific structure and principle, thereby regulating the pressure of the water passage.

[0046] By adjusting the pressure in the water passage 101, the pressure difference between water and gas can be controlled. A suitable water-gas pressure difference helps the gas dissolve more fully in the water, improving the uniformity and efficiency of gas-liquid mixing. For example, when the water pressure is adjusted to a value lower than the gas pressure, the gas can enter the water passage more smoothly and mix with the water, forming a higher-quality gas-liquid mixture, thereby improving the quality of micro-nano bubble water generation.

[0047] Please refer to Figure 3 In one possible implementation, the water pressure regulating component 105 is a pressure reducing valve 1051, which ensures that the water pressure in the water passage 101 is lower than the air pressure in the air passage 102. The pressure reducing valve 1051 is a device that controls fluid pressure by adjusting the valve opening. When water enters the water passage 101 and flows through the pressure reducing valve 1051, the spring, valve disc, and other components inside the valve 1051 function. The water exerts pressure on the valve disc; when this pressure exceeds the pressure value set by the pressure reducing valve 1051, the valve disc moves under the pressure difference, changing the flow cross-sectional area of ​​the water passage 101.

[0048] As the cross-sectional area of ​​the flow decreases, the resistance to water flow increases, thereby reducing the water pressure in the water passage 101. By reasonably setting the pressure of the pressure reducing valve 1051, it can be ensured that the water pressure in the water passage 101 is always lower than the air pressure in the air passage 102. Thus, at the gas-liquid mixing point (the junction of the water passage 101 and the air passage 102), because the air pressure in the air passage 102 is higher than the water pressure in the water passage 101, the gas will smoothly enter the water passage 101 under the action of the pressure difference and mix with the water.

[0049] Understandably, the pressure reducing valve 1051 can regulate the water pressure in the water passage 101 to make it lower than the gas pressure in the gas passage 102. This pressure difference control helps the gas dissolve into the water more evenly and efficiently, improving the quality of gas-liquid mixing and thus generating higher-quality micro-nano bubble water. For example, in some bathing scenarios where high bubble quality is required, precise pressure difference control can ensure the fineness and uniformity of the bubbles.

[0050] Please refer to Figure 4In one possible implementation, the water pressure regulating component 105 is a shut-off valve 1052 to close the water passage 101. The shut-off valve 1052 is a valve that controls the opening and closing of the passage by the raising and lowering of its valve disc. In the water passage 101, the shut-off valve 1052 is installed between the inlet end of the water passage 101 and the confluence point 104. When the shut-off valve 1052 is in the open state, there is a certain gap between the valve disc and the valve seat, allowing water to flow smoothly through the shut-off valve 1052 along the water passage 101 to the confluence point 104.

[0051] When it is necessary to close the water passage 101, the valve disc is moved downward by operating the valve stem of the shut-off valve 1052, gradually approaching the valve seat. Finally, the valve disc is tightly fitted onto the valve seat, completely blocking the water passage 101. At this time, water can no longer enter the confluence through the shut-off valve 1052, and the water passage 101 is in the closed state.

[0052] During the operation of the micro-nano bubble water device, users can adjust the gas-liquid mixing ratio or pause the gas-liquid mixing according to actual needs. In other words, the presence of the shut-off valve 1052 allows operators to easily close the water passage 101, thereby stopping the water supply and achieving flexible control over the gas-liquid mixing process. For example, at the initial startup of the device, the water passage 101 can be closed first, allowing gas to enter the dissolved air tank 2, and then the shut-off valve 1052 can be opened, allowing water to enter the dissolved air tank 2 and mix with the air inside.

[0053] Please refer to Figure 5 In one possible implementation, the water pressure regulating element 105 is a Venturi tube 1053, which has a constriction section 1053a, and the air passage 102 is connected to the constriction section 1053a. The Venturi tube 1053 is a device that utilizes the relationship between fluid velocity and pressure, characterized by the presence of the constriction section 1053a in the middle. When water enters from the inlet end of the water passage 101 and flows through the Venturi tube 1053, according to Bernoulli's principle in fluid mechanics, the fluid pressure is lower where the flow velocity is higher, and higher where the flow velocity is lower.

[0054] When water flows through the contraction section of the Venturi tube 1053, the flow velocity increases sharply due to the sudden decrease in the cross-sectional area of ​​the channel. As the flow velocity increases, the pressure at the contraction section 1053a decreases significantly, thus creating a negative pressure area at the contraction section 1053a.

[0055] Since the gas passage 102 is connected to the contraction section 1053a of the venturi tube 1053, the negative pressure formed in the contraction section 1053a will draw the gas in the gas passage 102 into the water passage 101. The water and gas are fully mixed in the contraction section 1053a and the subsequent expansion section to form a gas-liquid mixture, which then continues to flow to the confluence of the water passage 101 and the gas passage 102, and finally enters the dissolved air tank 2 to further generate micro-nano bubble water.

[0056] Understandably, the Venturi tube 1053 utilizes the energy changes of the water flow itself to achieve gas-liquid mixing, eliminating the need for additional power equipment to drive the gas into the water passage 101. This not only reduces the device's energy consumption and operating costs but also simplifies its structure and improves its reliability and stability. Simultaneously, its highly efficient gas-liquid mixing capability allows the gas to fully dissolve in the water within a short time, increasing the generation efficiency of micro / nano bubbles.

[0057] Please refer to Figures 2 to 5 In one possible implementation, the gas passage 102 is equipped with a one-way valve 106, which opens towards the confluence 104. The one-way valve 106 is a valve that allows fluid to flow in only one direction. In the gas passage 102, when gas enters from the gas source direction, the one-way valve 106 is subjected to gas pressure, and its valve disc opens under the pressure difference, allowing gas to pass smoothly through the one-way valve 106 and flow towards the confluence 104.

[0058] In this application, when water in the water passage 101 attempts to flow backward into the gas passage 102 due to abnormal pressure fluctuations (such as a sudden increase in water pressure) or other reasons, the water will exert a pressure on the valve disc of the one-way valve 106 that is opposite to the direction of permissible gas flow. At this time, the valve disc of the one-way valve 106 will close tightly under the action of this reverse pressure and its own structural design (such as spring force), preventing water from entering the gas passage 102.

[0059] Additionally, a make-up air pump 107 is provided between the one-way valve 106 and the inlet end of the gas passage 102. The make-up air pump 107 is a device for supplying gas to the gas passage 102. It draws in external gas through mechanical action, pressurizes it, and then delivers it into the gas passage 102. In the gas passage 102, the make-up air pump 107 is located between the one-way valve 106 and the inlet end of the gas passage 102.

[0060] When replenishing gas, the gas replenishment pump 107 starts, drawing gas from the external environment (such as air), compressing and pressurizing it to a certain pressure. The pressurized gas is then transported to the gas passage 102, flowing towards the confluence point 104. Due to the presence of the one-way valve 106, the gas can only flow in one direction towards the confluence point 104, preventing backflow. When the gas reaches the confluence point 104, it mixes with the water flowing out from the water passage 101, forming a gas-liquid mixture.

[0061] The air supply pump 107 actively and stably supplies gas to the gas passage 102, ensuring a sufficient and stable gas supply within the passage. This helps maintain a suitable water-gas pressure difference, enabling the gas to mix continuously and uniformly with water, improving the quality and efficiency of gas-liquid mixing, and thus ensuring the stable quality of the generated micro-nano bubble water. For example, in applications with high requirements for bubble concentration and size, a stable gas supply ensures that bubble generation meets standards.

[0062] Please refer to Figure 6 In one possible implementation, the water passage 101 is opposite to the gas passage 102. This opposing channel layout allows water and gas to meet at the confluence with the shortest path, reducing energy loss and time delay caused by the tortuous fluid path during mixing. Gas can enter the water flow more quickly, increasing the opportunity and time for gas-liquid contact, thereby improving the efficiency of gas-liquid mixing and contributing to the generation of micro- and nano-bubbles with higher concentrations and more uniform distribution.

[0063] This application also provides a water heater 3, including an inlet 301, an outlet 302, and the aforementioned micro-nano bubble water device. The inlet 301 is connected to an external water source, and the outlet 302 is connected to a water passage 101. External water enters the water heater 3 through the inlet 301, heats the water, and then passes it through the outlet 302 into the micro-nano bubble water device 100. The micro-nano bubble water device 100 generates micro-nano bubble water from the water, which users can use to clean dishes, fruits, etc., to improve cleaning effectiveness.
