Description

Technical Field

[0001] This invention belongs to the field of sparkling water production technology, specifically relating to an integrated sparkling water generator. Background Technology

[0002] Micro- and nanobubbles, as tiny gas units with diameters as small as 100 micrometers or less, exhibit remarkable durability, excellent gas-liquid exchange efficiency, significantly enhanced surface potential, and superior flotation performance. These unique physical properties enable micro- and nanobubble technology to shine in multiple fields, including but not limited to deep water purification, environmental restoration, high-end beauty and skincare, and surface cleaning of fruits and vegetables.

[0003] In the field of gas water heaters, the integration of micro-nano bubble technology has opened a new chapter in applications. Specifically, this technology, through ingenious design, allows air and water to be efficiently mixed within a carefully constructed dissolved air tank, utilizing the natural pressure of the piping system to generate supersaturated water rich in air. Subsequently, under the Venturi effect at the water outlet, these supersaturated dissolved gases are instantly released, forming unique milky white bubbly water, bringing users an unprecedented user experience.

[0004] However, current sparkling water generation systems are complex, encompassing a series of independent components such as shut-off valves, gas check valves, high-efficiency gas pumps, precision dissolved air tanks, and dedicated air inlet pipes. These components are tightly connected through numerous connection points and corresponding fasteners and seals. While this highly integrated structure ensures functionality, it also presents challenges such as large space requirements, cumbersome assembly processes, and high manufacturing costs. Ultimately, these cost factors are inevitably reflected in the product's market pricing, resulting in higher prices for gas water heaters equipped with sparkling water functionality, which to some extent limits the widespread adoption and application of this technology among a broader consumer base.

[0005] Therefore, the key to promoting the application of aerated water technology in the field of gas water heaters lies in how to simplify the system structure, miniaturize the equipment, optimize the assembly process, and reduce costs while ensuring the performance of the technology.

[0021] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0022] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to Figures 1 to 3 This invention provides an integrated sparkling water generator, which includes a dissolved air tank 100, a water inlet pipe 1, a liquid inlet valve, an air pump 9, an air valve, and a water outlet connector 4. The dissolved air tank 100 has a first dissolved air chamber 101 and a second dissolved air chamber 102. The first dissolved air chamber 101 is higher than the second dissolved air chamber 102. The first dissolved air chamber 101 and the second dissolved air chamber 102 are connected by a fluid channel 103, which is used to pump sparkling water from the first dissolved air chamber 101. The water is sent to the second dissolved air chamber 102, and the bubble water flows through the fluid channel 103 in a waterfall shape. The first dissolved air chamber 101 is also provided with a spray hole 21 that is connected to the water inlet pipe 1. The water inlet pipe 1 is connected to the first dissolved air chamber 101 through the liquid inlet valve. The air pump 9 is installed on the dissolved air tank 100. The air pump 9 is connected to the first dissolved air chamber 101 and the second dissolved air chamber 102 through the air valve. The water outlet connector 4 is connected to the second dissolved air chamber 102 and outputs the bubble water in the second dissolved air chamber 102 to the outside.

[0025] The present invention features a dual-cavity structure, and the fluid channel 103, in conjunction with the two dual cavities, allows the bubble water to flow and mix in a waterfall-like manner within the two cavities. To produce bubble water with the same effect, the present invention requires less compressed gas and water pressure in the dissolved air chamber and air pump 9. This ensures that the present invention simplifies the system structure, optimizes the assembly process, reduces costs, and makes the present invention more compact when used in water heaters.

[0026] A more preferred embodiment of the present invention is an integrated bubble water generator applied to a gas water heater.

[0027] In a preferred embodiment, the inner cavity of the dissolved gas tank 100 is provided with a baffle 6, which divides the inner cavity of the dissolved gas tank 100 into a first dissolved gas chamber 101 and a second dissolved gas chamber 102. The fluid channel 103 is formed by the gap between the baffle 6 and the inner cavity of the dissolved gas tank 100.

[0028] The bubble water produced in the first dissolved air chamber 101 above the baffle 6 generates a waterfall-like fluid as it passes through the fluid channel 103, greatly improving the production effect of bubble water. Then, it is mixed with gas again in the second dissolved air chamber 102, making it contain even more micro and nano bubbles.

[0029] The inner cavity of the dissolved gas tank 100 is divided into a first dissolved gas chamber 101 and a second dissolved gas chamber 102 by the baffle 6, so that the dissolved gas tank 100 and the baffle 6 can be formed separately, which facilitates the processing and forming of the integrated sparkling water generator, and also facilitates the assembly of the dissolved gas tank 100 and the baffle 6.

[0030] In a preferred embodiment, the baffle 6 is an arc-shaped groove with the opening of the arc-shaped groove facing upward. The first dissolved gas chamber 101 is formed by the concave cavity of the U-shaped groove. The fluid channel 103 is formed by the upper end of the U-shaped groove and the inner wall of the dissolved gas tank 100 cavity being spaced apart. The nozzle 21 is located below the fluid channel 103, and the spray direction of the nozzle 21 is towards the two arc-shaped sides of the U-shaped groove.

[0031] This design allows the sparkling water to flow upwards along the arc, maintaining a high flow velocity when it reaches the fluid channel 103, which is more conducive to the generation of a waterfall-like flow and micro / nano bubbles. The upward-facing slot design allows the sparkling water to flow and mix in the first and second dissolved air chambers 101 and 102 in an overflow manner, enhancing the sparkling water generation effect.

[0032] In a preferred embodiment, the baffle 6 is an arc-shaped groove with the opening of the U-shaped groove facing upward. A drain hole 61 is provided at the bottom of the U-shaped groove, and the drain hole 61 is connected to the first dissolved gas chamber 101 and the second dissolved gas chamber 102 through a valve.

[0033] During the inflation process, to ensure that the bubble water is discharged as quickly as possible, a drain hole 61 is provided on the baffle 6 to ensure that the bubble water in the first dissolved air chamber 101 in the upper part of the tank is discharged as quickly as possible. The air pump 9 first inflates the tank through the air inlet 22. After inflation is completed, when the water flows through the spray hole 21, the pressure increases due to the reduced cross-sectional area of ​​the flow channel, and the high-speed water is injected into the air in the tank, mixing with the air to form bubble water.

[0034] In a preferred embodiment, the dissolved gas tank 100 includes a tank shell 2 and a cover 7. The tank shell 2 has an inner cavity and an installation opening communicating with the inner cavity. The cover 7 is installed on the tank shell 2 and the cover 7 seals the installation opening. One end of the baffle 6 is installed on the inner side of the cover 7 and is also connected to the baffle 6. The end of the baffle 6 away from the cover 7 can be inserted into the inner cavity through the installation opening. The baffle 6 divides the inner cavity into upper and lower parts and forms a first dissolved gas chamber 101 and a second dissolved gas chamber 102.

[0035] Because the dissolved gas tank 100 has a small overall volume, it is designed with a tank shell 2, a cover 7 and an installation opening, and is equipped with a baffle 6, making installation more convenient.

[0036] In a preferred embodiment, the installation opening of the outer shell 2 is located on the left end, and a connector 62 is provided on the right inner wall of the outer shell 2. The connector 62 is positioned facing the left end, and the right side of the baffle 6 is inserted into the connector 62. The right side of the baffle 6 abuts against the right inner wall of the outer shell 2, and the left side of the baffle 6 abuts against the inner side of the cover 7.

[0037] Unless otherwise stated or contradicted in the text, the terms left and right, up and down, and front and back refer to the same meaning. Figure 2 For reference, the length of the baffle 6 in the left-right direction matches the length of the cavity in the tank shell 2 in the left-right direction. The connector 62 is generally cylindrical, and the baffle 6 is provided with a connector hole. The connector hole mates with the connector 62, so that the right end of the baffle 6 is supported and fixed to the right inner wall of the tank shell 2. The connector installation method avoids the difficulty of installing the baffle 6 due to the small volume of the tank's inner cavity.

[0038] In a preferred embodiment, the front end, rear end and left end of the baffle 6 are provided with upward-facing arc-shaped sections, and the nozzles 21 are respectively facing one of the three arc-shaped sections of the baffle 6. Generally, the nozzles spray onto the arc surface of the baffle in front and then flow back to spray onto the other arc-shaped surfaces. The concave surfaces of the three arc-shaped sections face upward, and the fluid channel 103 is located above the three arc-shaped sections.

[0039] The fluid channel 103 is located above the front end, rear end, and left end of the baffle 6, or in combination with the front end and rear end of the baffle 6. The nozzle 21 sprays water towards the arc-shaped section, allowing the water to mix with the gas in the first dissolved air chamber 101 to initially form bubble water. The bubble water has a high upward velocity when it is sprayed toward the arc-shaped baffle 6, and a high downward velocity when it flows to the fluid channel 103 at the top of the baffle 6.

[0040] In a preferred embodiment, a sealing gasket 8 is connected between the outer shell 2 and the cover 7, and the sealing gasket 8 is arranged in a ring around the outer periphery of the installation opening.

[0041] The sealing gasket 8 ensures a sealed connection between the outer shell and the cover 7, thereby ensuring the airtightness of the tank shell 2.

[0042] In a preferred embodiment, the water outlet connector 4 is located at the bottom of the second dissolved air chamber 102 to facilitate the complete discharge of the bubble water. The lower end of the second dissolved air chamber 102 is provided with an air inlet 22 that communicates with the air pump 9. The air valve is a one-way valve 3, which can prevent the bubble water from entering the air pump 9 and the air supply system such as the air delivery channel.

[0043] In a preferred embodiment, the air inlet 22 and the spray nozzle 21 are located on the same side of the inner cavity of the dissolved air tank 100, and the liquid inlet valve is a shut-off valve 5. The shut-off valve 5, the air pump 9, and the one-way valve 3 are located on the same outer side of the dissolved air tank 100. Through the reasonable arrangement of the above-mentioned components, the integrated sparkling water generator is made smaller in size.

[0044] In use, the power supply line supplies power to the shut-off valve 5 and the air pump 9. The shut-off valve 5 closes to cut off the water inlet pipe 1, and the air pump 9 fills the tank with air through the one-way valve 3 and the air inlet 22. When the tank is full of air, the power supply line stops supplying power, the shut-off valve 5 opens, and the water flows through the smaller diameter nozzle 21, increasing the pressure and flow rate. The water mixes in the tank to form high-concentration oxygen-enriched bubble water, which flows out through the outlet. The dissolved air tank 100 has a dual-chamber structure. The first dissolved air chamber 101 of the dissolved air chamber baffle 6 is for initial dissolved air. After the first dissolved air chamber 101 is filled with water, the bubble water overflows and flows in a waterfall-like manner through the fluid channel 103 to the second dissolved air chamber 102, thus forming multiple stages of gradual dissolved air. The overflowing and waterfall-like flow of bubble water further dissolves the air.

[0045] The present invention, through the combination of the above-described structures, also has the following significant beneficial effects:

[0046] The device integrates an air pump (9), a shut-off valve (5), and a check valve (3) within a very small volume (<1 dm of the inlet pipe). 3 It enables oxygen-enriched bubble baths, achieving water purification, skin care, and fruit and vegetable cleaning effects through micro-nano bubble technology. It also allows users to switch between oxygen-enriched bubble baths and regular baths at any time.

[0047] Tank shell 2: This device is easy to connect. It only needs to be connected to the water line before the water outlet connector 4. The electrical control module only needs to provide a 4V power supply to the water outlet connector of the tank shell 2.

[0048] The one-way valve 3 and the dissolved gas tank 100 adopt a U-shape with a semi-circular baffle 6 to form a water waterfall and increase the contact area between water and gas.

[0049] The water outlet connector 4 and the upper shell of the dissolved gas tank 100 include a spray hole 21 to increase the water pressure injected into the tank and enhance the gas-liquid mixing effect.

[0050] 5. The gate valve has fewer connection structures, fewer potential leaks, and high reliability.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.
