Due to their small size, micro-nano bubbles exhibit properties distinct from those of ordinary bubbles, such as long lifespan, high interfacial zeta potential (the shear plane potential, also known as electrokinetic potential or zeta potential, a key indicator of colloidal dispersion stability), and high mass transfer efficiency. Leveraging these properties, micro-nano bubble water can effectively degrade pesticide residues in fruits and vegetables, kill bacteria and some viruses, and effectively remove antibiotics and hormones from some meats. Currently, micro-nano bubble water is widely used in industrial water treatment and water pollution control. Technical issues

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] Based on the current bubble generation mechanism, micro-nano bubble water generation technology can be divided into pressurized dissolved air method, air induction method, and electrolytic precipitation method. Existing air dissolving devices that generate micro-nano bubble water through pressurized dissolved air method are generally large and costly. The noise and vibration generated by the air dissolving devices are also high, making them unsuitable for home use.

[0046] Micro-nano bubble water refers to water containing a large number of micro-nano bubbles with diameters ranging from 0.1 to 50 μm. Due to their small size, these bubbles exhibit properties distinct from those of ordinary bubbles, such as long lifespan, high interfacial zeta potential, and high mass transfer efficiency. Leveraging these properties, micro-nano bubble water can effectively degrade pesticide residues in fruits and vegetables, kill bacteria and some viruses, and effectively remove antibiotics and hormones from some meats. Currently, micro-nano bubble water is widely used in industrial water treatment and water pollution control.

[0047] Based on the current bubble generation mechanism, micro-nano bubble water generation technology can be divided into pressurized dissolved air method, air induction method, and electrolytic precipitation method. Existing air dissolving devices that generate micro-nano bubble water through pressurized dissolved air method are generally large and costly. The noise and vibration generated by the air dissolving devices are also high, making them unsuitable for home use.

[0048] In order to solve the above problems, the present application proposes a dissolved air device to facilitate its home use.

[0049] 1 to 10 , in one embodiment of the present application, the gas dissolving device includes:

[0050] First water supply branch 10;

[0051] Gas supply branch 20;

[0052] Output branch 30;

[0053] The bubble water generating assembly 40, the first water supply branch 10, the air supply branch 20 and the output branch 30 are respectively connected to the bubble water generating assembly 40; and

[0054] The control device 50 is electrically connected to the first water supply branch 10 and the output branch 30 respectively; the control device 50 is used to control the working status of the first water supply branch 10 and the output branch 30 so that the bubble water generating component 40 generates micro-nano bubble water.

[0055] In the present embodiment, the prior art generally pressurizes air by the pressurized dissolved air method, so that the air is dissolved in water under pressurized conditions to reach a supersaturated state, and the supersaturated air dissolved is released in the form of micro-nano bubble water when the pressure drops to normal pressure, thereby producing micro-nano bubble water. The existing dissolved air device for producing micro-nano bubble water generally needs to be equipped with a pressurizing device such as an air compressor and a booster pump to pressurize the air, and the pressurizing device is generally large in size and high in cost, and the noise and vibration generated by the pressurizing device during operation are large, so that when the above-mentioned dissolved air device is used at home, for example, it is connected to a household water heater, a shower head, or a water outlet switch, not only a large amount of space is taken up, but also the noise and vibration generated by the operation of the above-mentioned dissolved air device are large, which seriously affects the user's experience. Therefore, there is an urgent need for a low-cost, small-volume, and low-noise and low-vibration dissolved air device that can be used at home.

[0056] In this embodiment, the first water supply branch 10 is used to supply water to the bubble water generating assembly 40, the air supply branch 20 is used to introduce air into the bubble water generating assembly 40, and the output branch 30 is used to pump water out of the bubble water generating assembly 40. A control device 50 is used to control the operating states of the first water supply branch 10 and the output branch 30. The bubble water generating assembly 40 has a cavity within it. When a user requires micro-nano bubble water, the control device 50 controls the first water supply branch 10 to close and the output branch 30 to open. When the output branch 30 opens, the micro-nano bubble water within the bubble water generating assembly 40 is discharged for the user's use. At this time, the micro-nano bubble water is discharged from the bubble water generating assembly 40, creating a negative pressure within the cavity of the bubble water generating assembly 40, causing air to be automatically drawn into the cavity of the bubble water generating assembly 40 through the air supply branch 20. When the water level in the bubble water generating component 40 is lower than the preset first water level, the control device 50 controls the first water supply branch 10 to open and the output branch 30 to close. At this time, the first water supply branch 10 supplies water to the bubble water generating component 40, and mixes water and air in the cavity of the bubble water generating component 40, thereby generating micro-nano bubble water.

[0057] Thus, in this embodiment, the operating states of the first water supply branch 10 and the output branch 30 are controlled by the control device 50, and water and air are mixed within the bubble water generating assembly 40 to generate micro-nano bubble water without the need for an additional pressurizing device. Since a pressurizing device is not required, the production cost of the air dissolving device is effectively reduced, and the air dissolving device is made smaller. When the air dissolving device is used at home, for example, by connecting it to a household water heater, shower, or water outlet valve, it does not occupy a large amount of space. Furthermore, the noise and vibration generated by the operation of the air dissolving device are effectively reduced, improving the user experience and facilitating the use of the air dissolving device at home.

[0058] In this embodiment, the operation of the gas dissolving device is controlled simply. A processor such as a CPU, MCU, or DSP, or a commonly used control chip on the market, is provided within the control device 50 to enable the control device 50 to achieve the desired control effect. In one embodiment, the user can also directly control the operating states of the first water supply branch 10 and the output branch 30 through the control circuit to achieve the same effect.

[0059] 2 , in another embodiment of the present application, the gas dissolving device includes a first regulating device 11 disposed in the first water supply branch 10 , and the first regulating device 11 is electrically connected to the control device 50 ; the first regulating device 11 is used to regulate the water flow in the first water supply branch 10 .

[0060] In this embodiment, the first regulating device 11 includes a first water valve. The opening and closing state of the first water valve is adjusted by the control device 50, so that the water flow in the first water supply branch 10 can be adjusted. When the first water valve is completely closed, the first water supply branch 10 stops supplying water to the bubble water generating component 40. When the first water valve is fully opened, the first water supply branch 10 maintains the maximum water flow to supply water to the bubble water generating component 40. When the first water valve is fully opened and the first water supply branch 10 maintains the maximum water flow to supply water to the bubble water generating component 40, a larger vortex can be generated in the bubble water generating component 40, thereby improving the efficiency of mixing water and air in the bubble water generating component 40 to produce micro-nano bubble water. As an optional solution but not a limitation, the air dissolving device also includes a water pump arranged in the water supply branch 10. By arranging the water pump in the water supply branch 10, the water pressure in the first water supply branch 10 can be increased, so as to further increase the vortex generated in the bubble water generating component 40 when the first water supply branch 10 supplies water to the bubble water generating component 40, thereby further improving the efficiency of mixing water and air in the bubble water generating component 40 to produce micro-nano bubble water.

[0061] 3 , in another embodiment of the present application, the gas dissolving device includes a second regulating device 31 disposed in the output branch 30 , and the second regulating device 31 is electrically connected to the control device 50 ; the second regulating device 31 is used to regulate the water flow in the output branch.

[0062] In another embodiment of the present application, the gas dissolving device also includes a water pump arranged in the output branch 30, the water pump is electrically connected to the control device 50, and the second regulating device 31 includes a second water valve. By starting the water pump and adjusting the opening and closing state of the second water valve by the control device 50, the water flow in the output branch 30 can be adjusted; when the water pump is started and the second water valve is fully opened, the output branch 30 maintains the maximum water flow to output the micro-nano bubble water in the bubble water generating component 40; when the second water valve is fully closed, the output of the micro-nano bubble water from the bubble water generating component 40 is stopped. Since the micro-nano bubble water in the bubble water generating component 40 is output through the output branch 30, a negative pressure is formed in the bubble water generating component 40. When the water pump is turned off and the second water valve is closed at the same time, the micro-nano bubble water output by the water pump can be effectively prevented from flowing back, thereby ensuring the normal use of the micro-nano bubble water by the user.

[0063] 4 to 6 , in yet another embodiment of the present application, the gas dissolving device includes a flow detection device 12 , which is electrically connected to the control device 50 ; the flow detection device 12 is disposed in at least one of the first water supply branch 10 and the output branch 30 ;

[0064] The flow detection device 12 is used to detect the water flow and output a corresponding flow detection signal;

[0065] The control device 50 is used to control the working state of the first water supply branch 10 and the output branch 30 according to the flow detection signal;

[0066] and / or,

[0067] The liquid level detection device 41 is electrically connected to the control device 50; the liquid level detection device 41 is disposed in the bubble water generating assembly 40;

[0068] The liquid level detection device 41 is used to detect the liquid level in the bubble water generating assembly 40 and output a corresponding liquid level detection signal;

[0069] The control device 50 is used to control the working states of the first water supply branch 10 and the output branch 30 according to the liquid level detection signal.

[0070] In one embodiment of the present application, the flow detection device 12 is a water flow sensor, which is electrically connected to the control device 50 and disposed within the first water supply branch 10. A user can set a refresh time for the micro-nano bubble water within the bubble water generating assembly 40. In one embodiment, the refresh time is the time it takes for the user to completely use up the preset first volume of water within the bubble water generating assembly 40. At each refresh time interval, the control device 50 controls the output branch 30 to close and the first water supply branch 10 to open. The control device 50 uses the water flow sensor to determine the water flow within the first water supply branch 10 and controls the first water supply branch 10 to open for a corresponding preset first time, thereby restoring the preset first volume of water within the bubble water generating assembly 40 and allowing water and air to mix within the bubble water generating assembly 40 to regenerate micro-nano bubble water for user use.

[0071] In another embodiment of the present application, the flow detection device 12 is a water flow sensor electrically connected to the control device 50 and disposed within the output branch 30. In this embodiment, a preset second time for the water level in the bubble water generating assembly 40 to reach a preset second water volume via the first water supply branch 10 can be precalculated. The water flow sensor can determine the volume of micro-nano bubble water output from the output branch 30 based on the time and water flow rate of micro-nano bubble water output via the output branch 30. When the user consumes the bubble water in the bubble water generating assembly 40, causing the water volume output from the output branch 30 to reach the preset second water volume, the control device 50 controls the output branch 30 to close and the first water supply branch 10 to open for a second time, allowing the water level in the bubble water generating assembly 40 to return to the preset second water volume. Water and air are then mixed within the bubble water generating assembly 40 to regenerate micro-nano bubble water for the user's consumption.

[0072] In another embodiment of the present application, the flow detection device 12 includes a first water flow sensor and a second water flow sensor, both of which are electrically connected to the control device 50. The first water flow sensor is disposed in the first water supply branch 10, and the second water flow sensor is disposed in the output branch 30. The first water flow sensor can determine the amount of water flowing into the bubble water generating assembly 40 based on the water supply time and water flow rate through the first water supply branch 10. The second water flow sensor can determine the amount of water output from the bubble water generating assembly 40 based on the time and water flow rate of micro-nano bubble water output through the output branch 30. By determining the amount of water flowing into the bubble water generating assembly 40 and the amount of water output from the bubble water generating assembly 40, the current amount of water in the bubble water generating assembly 40 can be determined.

[0073] In this embodiment, when a user consumes micro-nano bubble water and the water level in the bubble water generating assembly 40 falls below a preset third water level, the control device 50 controls the output branch 30 to close and the first water supply branch 10 to open for a third time, allowing the water level in the bubble water generating assembly 40 to reach a preset fourth water level. This allows water and air to mix within the bubble water generating assembly 40 to produce micro-nano bubble water for the user's use. When the water level in the bubble water generating assembly 40 exceeds the preset fourth water level, the control device 50 controls the first water supply branch 10 to close. The above steps are repeated until the water level in the bubble water generating assembly 40 falls below the preset third water level, wherein the preset fourth water level is greater than the preset third water level. This arrangement ensures that the micro-nano bubble water in the bubble water generating assembly 40 always reaches a level between the preset third and fourth water levels. This not only allows for timely replenishment of the micro-nano bubble water in the bubble water generating assembly 40 when it is insufficient, but also prevents the situation where excessive water in the bubble water generating assembly 40 causes insufficient air, which in turn prevents the generation of micro-nano bubble water.

[0074] In one embodiment of the present application, the liquid level detection device 41 includes a liquid level sensor electrically connected to the control device 50. The liquid level sensor is disposed near the bottom of the bubble water generating assembly 40 and is configured to detect the liquid level within the bubble water generating assembly 40 and output a corresponding liquid level detection signal. A predetermined third time for the water level within the bubble water generating assembly 40 to reach a predetermined first liquid level via the first water supply branch 10 can be precalculated. When the liquid level sensor detects that the liquid level within the bubble water generating assembly 40 falls below the predetermined first liquid level, the liquid level detection signal is output, causing the control device 50 to close the output branch 30 and open the first water supply branch 10 for a predetermined third time, thereby allowing water and air to mix within the bubble water generating assembly 40 to produce micro-nano bubble water for user consumption.

[0075] In another embodiment of the present application, the liquid level detection device 41 includes a liquid level sensor electrically connected to the control device 50. The liquid level sensor is disposed near the top of the bubble water generating assembly 40 and is configured to detect the liquid level within the bubble water generating assembly 40 and output a corresponding liquid level detection signal. A user can set a refresh time for the micro-nano bubble water within the bubble water generating assembly 40. In one embodiment, the refresh time is the time it takes for the user to completely consume the micro-nano bubble water at a preset second level within the bubble water generating assembly 40. At each refresh time interval, the control device 50 controls the output branch 30 to close and the first water supply branch 10 to open, allowing water and air to mix within the bubble water generating assembly 40 to generate micro-nano bubble water. Simultaneously, the control device 50 determines whether the liquid level within the bubble water generating assembly 40 has reached the preset second level. When the liquid level sensor detects that the liquid level within the bubble water generating assembly 40 has reached the preset second level, it outputs a corresponding liquid level detection signal, causing the control device 50 to control the first water supply branch 10 to close.

[0076] In one embodiment, the liquid level detection device 41 includes a first liquid level sensor and a second liquid level sensor, and the first liquid level sensor and the second liquid level sensor are both electrically connected to the control device 50, wherein the first liquid level sensor is arranged near the bottom position in the bubble water generating component 40, and the second liquid level sensor is arranged near the top position in the bubble water generating component 40, and the first liquid level sensor and the second liquid level sensor are used to detect the liquid level in the bubble water generating component 40 and output corresponding liquid level detection signals. In this embodiment, when the user uses micro-nano bubble water to make the liquid level in the bubble water generating component 40 lower than the preset first liquid level, the first liquid level sensor outputs a corresponding liquid level detection signal to enable the control device 50 to control the output branch 30 to be closed and the first water supply branch 10 to be opened, so that water and air are mixed in the bubble water generating component 40 to produce micro-nano bubble water. When the liquid level in the bubble water generating component 40 reaches the preset second liquid level, the second liquid level sensor outputs a corresponding liquid level detection signal to enable the control device 50 to control the first water supply branch 10 to be closed. The user uses micro-nano bubble water to gradually lower the liquid level in the bubble water generating component 40 from the preset second liquid level. When it reaches the preset first liquid level, the above steps are repeated, and micro-nano bubble water can be continuously generated.

[0077] 7 , in another embodiment of the present application, the gas dissolving device further includes a backflow prevention mechanism 21 disposed in the gas supply branch 20 , the backflow prevention mechanism being configured to prevent backflow of water and gas within the bubble water generating assembly 40 .

[0078] In one embodiment, the backflow prevention mechanism 21 includes a one-way valve. In this embodiment, when the one-way valve is not provided, when the first water supply branch 10 supplies water to the bubble water generating assembly 40, the water will directly squeeze the air out of the air supply branch 20, preventing the water and air from dissolving in large quantities within the bubble water generating assembly 40, thereby preventing the generation of micro-nano bubble water. The provision of a one-way valve can pressurize the water and air within the bubble water generating assembly 40, thereby effectively generating micro-nano bubble water. As an optional, but not limiting, solution, the backflow prevention mechanism 21 is provided at one end of the air supply branch 20 near the bubble water generating assembly 40. Since water is supplied to the bubble water generating assembly 40 via the first water supply branch 10, the air supply branch 20 may become blocked due to an excessively high water level within the bubble water generating assembly 40, thereby reducing the air supply efficiency of the air supply branch 20. The provision of a one-way valve ensures that the air supply branch 20 can properly flow air into the bubble water generating assembly 40.

[0079] In one embodiment, the air dissolving device further includes a heating device 70; the heating device 70 may be a pipe-type electric heater, a water heater, a heat exchanger, or the like. The heating device 70 is disposed in at least one of the first water supply branch 10, the output branch 30, and the bubble water generating assembly 40. By disposing the heating device 70 in at least one of the first water supply branch 10, the output branch 30, and the bubble water generating assembly 40, the water in the air dissolving device can be heated, providing the user with micro-nano bubble water at a higher temperature, which is beneficial for use of the air dissolving device in cold environments. Furthermore, disposing the heating device 70 in the first water supply branch 10 and / or the bubble water generating assembly 40 can also increase the temperature within the bubble water generating assembly 40, causing the air introduced into the bubble water generating assembly 40 to expand, further accelerating the efficiency of water-air dissolution, and thereby improving the efficiency of micro-nano bubble water generation.

[0080] In one embodiment, the air dissolving device further includes an air pump 22 disposed within the air supply branch 20, which is electrically connected to the control device. The provision of the air pump 22 within the air supply branch 20 improves the efficiency of the air supply branch 20 in supplying air to the bubble water generating assembly 40 and simultaneously increases the pressure within the bubble water generating assembly 40, thereby improving the efficiency of generating micro-nano bubble water.

[0081] 9-10 , in another embodiment of the present application, the dissolved gas device further includes a second water supply branch 60 , which is connected to the output branch 30 , and a controlled end of the second water supply branch 60 is electrically connected to the control device 50 .

[0082] In one embodiment, the second water supply branch 60 includes a third water valve electrically connected to the control device 50. The third water valve is used to regulate the water flow within the second water supply branch 60. In one embodiment, the second water supply branch 60 and the first water supply branch 10 share the same water inlet port. Of course, the second water supply branch 60 can also be connected to a different water inlet port from the first water supply branch. When the third water valve is opened, water can be supplied to the user through the second water supply branch 60 alone. When the third water valve and the second water valve are opened simultaneously, the water supplied by the second water supply branch 60 can be mixed with the micro-nano bubble water in the output branch 30 and output for user use.

[0083] In this embodiment, when the user uses micro-nano bubble water and the liquid level in the bubble water generating component 40 is lower than the preset first liquid level, the first liquid level sensor outputs a corresponding liquid level detection signal to enable the control device 50 to control the first water supply branch 10 and the second water supply branch 60 to be opened and the output branch 30 to be closed, so that water and air are mixed in the bubble water generating component 40 to produce micro-nano bubble water. At the same time, the water supplied by the first water supply branch 10 is mixed with the previously output micro-nano bubble water for user use. Since there is generally a long pipeline between the bubble water generating component 40 and the user's water use end, the water supplied by the second water supply branch 60 is mixed with the micro-nano bubble water output by the output branch 30 and output to the user, which will not significantly reduce the water content. The micro-nano bubble content in the pipeline between the low-bubble water generating assembly 40 and the user's water consumption end will not affect the user's normal use of the micro-nano bubble water. When the liquid level in the bubble water generating assembly 40 reaches a preset second liquid level, the second liquid level sensor outputs a corresponding liquid level detection signal to cause the control device 50 to control the first water supply branch 10 and the second water supply branch 60 to be closed, and the output branch 30 to be opened to output the micro-nano bubble water in the bubble water generating assembly 40 directly for use by the user. When the user uses the micro-nano bubble water and the liquid level in the bubble water generating assembly 40 gradually decreases from the preset second liquid level to the preset first liquid level again, the above steps are repeated, and the micro-nano bubble water can be continuously supplied to the user through the air dissolving device.

[0084] In the embodiments of the present application, the technical solution of the present application is illustrated by taking the generation of micro-nano bubble water as an example, but it is not intended to limit the technical solution of the present application. Ordinary bubble water can also be generated through the technical solution of the present application.

[0086] In one embodiment, the water supply system further includes at least one release mechanism, which is connected to the output branch 30. In one embodiment, the release mechanism can be a water outlet switch, a shower head, etc. The release mechanism can be selectively installed according to the actual scenario to adapt to different water use scenarios such as kitchen water use and bathroom water use.
