Description

Technical Field

[0001] This disclosure relates to the field of microbubble water dispensing equipment technology, and in particular to a water dispensing device, a microbubble generating device and a control method thereof. Background Technology

[0002] As people's living standards improve, they have increasingly higher requirements for household water, such as water for bathing, washing fruits and vegetables, and cleaning dishes. They not only require that household water be pollution-free, but also that the cleaning effect be obvious. To address this, microbubble generators have been developed, which can turn water mixed with air and other gases into microbubble water. When water contains microbubbles, the cleaning effect can be enhanced.

[0003] In related technologies, microbubble generators include water-air mixing tanks, which mainly come in two types. One type can only add air to the water in the water-air mixing tank without increasing the pressure of the tank, resulting in low dissolved oxygen levels in the water. The other type uses a booster pump and an air pump to pressurize and add air, which can increase the dissolved oxygen levels in the water, but it is more expensive, consumes more energy, and generates more noise. Summary of the Invention

[0004] The purpose of this disclosure is to provide a water outlet device, a microbubble generator and its control method to increase the dissolved oxygen content in water and reduce energy consumption and noise.

[0005] To achieve the above objectives, this disclosure provides a microbubble generator, comprising a pressurizing device, a water-air mixing container, and an air replenishment and circulation container. The inlet of the pressurizing device is connected to an external water source, and the inlet of the pressurizing device is equipped with a first valve. The outlet of the pressurizing device is connected to the first inlet of the water-air mixing container through a second valve, and the outlet of the pressurizing device is connected to the water inlet of the air replenishment and circulation container through a third valve. The air outlet of the air replenishment and circulation container is connected to the second inlet of the water-air mixing container through a first check valve, and the water outlet of the water-air mixing container is connected to a microbubble water outlet terminal.

[0006] In one embodiment of this disclosure, the outlet of the air replenishment circulation container is connected to the inlet of the pressurization device through a fourth valve, and a second check valve is provided between the fourth valve and the inlet of the pressurization device; the air inlet of the air replenishment circulation container is connected to the outside air through a third check valve.

[0007] In one embodiment of this disclosure, a fourth check valve is provided between the second valve and the first inlet of the water-air mixing container, and a fifth check valve is provided between the third valve and the water inlet of the air replenishment circulation container.

[0008] In one embodiment of this disclosure, the inlet of the booster device is provided with a sixth check valve, which is located between the first valve and the inlet of the booster device.

[0009] In one embodiment of this disclosure, the outlet of the water-air mixing container is provided with a fifth valve.

[0010] In one embodiment of this disclosure, both the water-air mixing container and the air replenishment circulation container are equipped with liquid level sensors for detecting the liquid level.

[0011] For the purposes described above, this disclosure also provides a water outlet device, including a microbubble water outlet terminal and the microbubble generating device, wherein the microbubble water outlet terminal is connected to the outlet of the water-air mixing container.

[0012] To achieve the above objectives, this disclosure also provides a control method for a microbubble generator, the control method comprising the following steps:

[0013] By opening the first and second valves, the pressurization device delivers external water to the water-air mixing container, so that the air and water in the water-air mixing container are mixed. The mixed water enters the microbubble water outlet terminal from the outlet of the water-air mixing container to form microbubble water.

[0014] The liquid level in the water-air mixing container is obtained. When the liquid level reaches a high level, the second valve is closed and the third valve is opened. The pressurization device delivers external water to the air replenishment circulation container, so that the air in the air replenishment circulation container is forced into the water-air mixing container through the first check valve. After the water and air in the water-air mixing container are mixed, they enter the microbubble water outlet terminal from the outlet of the water-air mixing container to form microbubble water.

[0015] In one embodiment of this disclosure, after the pressurization device delivers external water to the air replenishment and circulation container, it further includes:

[0016] The liquid level in the gas replenishment circulation container is obtained. When the liquid level reaches a high level, the first valve and the third valve are closed, and the second valve and the fourth valve are opened. The pressurization device transports the water in the gas replenishment circulation container to the water-air mixing container. Outside air enters the gas replenishment circulation container through the third check valve.

[0017] In one embodiment of this disclosure, after the pressurization device delivers water from the air replenishment circulation container to the water-air mixing container, the method further includes:

[0018] The liquid level in the gas replenishment and circulation container is obtained. When the liquid level is low, the operation of opening the first valve and the second valve is repeated, and the pressurization device delivers external water to the water-air mixing container.

[0019] The main beneficial effects of this disclosure are:

[0020] The microbubble generator disclosed herein controls the connection between a pressurizing device, a water-air mixing container, and an air replenishment circulation container through a first valve, a second valve, and a third valve. This achieves pressurization and air replenishment without the use of an air pump, increasing the dissolved oxygen content in the water within the water-air mixing container and reducing energy consumption and noise. In use, opening the first and second valves allows the pressurizing device to supply external water to the water-air mixing container. As the pressurizing device increases the pressure, the air and water in the container mix thoroughly, increasing the dissolved oxygen content. The pressure then decreases instantaneously at the outlet of the water-air mixing container and the microbubble outlet terminal, reducing the solubility of oxygen in the water. This releases and decomposes the oxygen into tiny microbubbles, producing microbubble water with a high microbubble content and a significant cleaning effect. During this process, the air content in the water-air mixing container gradually decreases, and the liquid level gradually rises. When the liquid level rises to the high level, the second valve is closed and the third valve is opened. At this time, external water enters the air replenishment circulation container through the pressurization device, causing the liquid level in the air replenishment circulation container to rise. This forces the air in the air replenishment circulation container to be forced into the water-air mixing container through the first check valve from the air outlet of the air replenishment circulation container, replenishing the water-air mixing container with air. At the same time, due to the pressure increase in the water-air mixing container by the pressurization device, the air and water in the water-air mixing container can be fully mixed, and the dissolved oxygen in the water increases. Through the water outlet of the water-air mixing container and the microbubble water outlet terminal, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0033] See Figures 1 to 4 As shown, this embodiment provides a microbubble generator, including a pressurizing device 1, a water-air mixing container 2, and an air replenishment and circulation container 3. The inlet of the pressurizing device 1 is used to connect with an external water source. A first valve 4 is provided at the inlet of the pressurizing device 1. The outlet of the pressurizing device 1 is connected to the first inlet of the water-air mixing container 2 through a second valve 5. The outlet of the pressurizing device 1 is connected to the water inlet of the air replenishment and circulation container 3 through a third valve 6. The air outlet of the air replenishment and circulation container 3 is connected to the second inlet of the water-air mixing container 2 through a first check valve 11. The water outlet of the water-air mixing container 2 is used to connect with a microbubble water outlet terminal 20.

[0034] The microbubble generator provided in this embodiment controls the connection between the pressurization device 1, the water-air mixing container 2, and the air replenishment circulation container 3 through the first valve 4, the second valve 5, and the third valve 6. This achieves pressurization and air replenishment without using an air pump, increasing the dissolved oxygen content in the water within the water-air mixing container 2 and reducing energy consumption and noise. In use, the outlet of the water-air mixing container 2 is connected to the microbubble water outlet terminal 20. (See [reference]). Figure 2 As shown, arrow A indicates the flow direction of the external water source. When the first valve 4 and the second valve 5 are opened, the pressurizing device 1 delivers the external water source to the water-air mixing container 2. With the pressurizing device 1 increasing the pressure, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantly, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water with a high microbubble content and obvious cleaning effect.

[0035] During this process, the air inside the water-air mixing container 2 gradually decreases, and the liquid level gradually rises. (See also...) Figure 3As shown, when the liquid level rises to a high level, the second valve 5 is closed and the third valve 6 is opened. At this time, external water enters the air replenishment circulation container 3 through the pressurization device 1, causing the liquid level in the air replenishment circulation container 3 to rise. This forces the air in the air replenishment circulation container 3 to be forced from the air outlet of the air replenishment circulation container 3 through the first check valve 11 into the water-air mixing container 2, replenishing the water-air mixing container 2 with air. At the same time, as the pressurization device 1 increases the pressure in the water-air mixing container 2, the air and water in the water-air mixing container 2 can be fully mixed, increasing the dissolved oxygen in the water. Through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

[0036] In one embodiment, both the water-air mixing container 2 and the air replenishment and circulation container 3 are equipped with liquid level sensors for detecting the liquid level.

[0037] For example, see Figure 1 As shown, the liquid level sensor includes a high liquid level probe 9 and a low liquid level probe 10. Taking the water-air mixing container 2 as an example, the high liquid level probe 9 is set near the top of the water-air mixing container 2, and the low liquid level probe 10 is set near the bottom of the water-air mixing container 2.

[0038] It should be noted that the structure and working principle of the high liquid level probe 9 and the low liquid level probe 10 are existing technologies and will not be described in detail here.

[0039] In one embodiment, the outlet of the air replenishment circulation container 3 is connected to the inlet of the booster device 1 through the fourth valve 7, and a second check valve 12 is provided between the fourth valve 7 and the inlet of the booster device 1; the air inlet of the air replenishment circulation container 3 is connected to the outside air through the third check valve 13.

[0040] When external water enters the air replenishment circulation container 3 through the pressurization device 1, the liquid level in the air replenishment circulation container 3 rises, thereby forcing the air in the air replenishment circulation container 3 from the air outlet of the air replenishment circulation container 3 through the first check valve 11 into the water-air mixing container 2, replenishing the water-air mixing container 2 with air; see also Figure 4 As shown, arrow B indicates the direction of airflow. When the liquid level in the air replenishment circulation container 3 rises to the high level, the first valve 4 and the third valve 6 are closed, and the second valve 5 and the fourth valve 7 are opened. Under the action of the pressurizing device 1, the water in the air replenishment circulation container 3 is drawn into the water-air mixing container 2 through the second check valve 12, and the liquid level in the air replenishment circulation container 3 drops accordingly. At this time, the third check valve 13 opens under the action of negative pressure in the air replenishment circulation container 3, and outside air is drawn into the air replenishment circulation container 3, thereby replenishing air into the air replenishment circulation container 3 to ensure that the microbubble generator can work continuously.

[0041] In this embodiment, the water in the air replenishment circulation container 3 can not only pressurize air into the water-air mixing container 2, but also, when the liquid level in the water-air mixing container 2 rises to a high level, the water in the air replenishment circulation container 3 can be drawn into the water-air mixing container 2 for use under the action of the pressurizing device 1 through the fourth valve 7 and the second check valve 12. In this way, the water in the air replenishment circulation container can be recycled to ensure that it is not stagnant water, but flowing and circulating fresh water, thereby ensuring that the air replenishment circulation container is not prone to bacterial growth and odor.

[0042] See Figure 2 As shown, when the liquid level in the air replenishment circulation container 3 drops to a low level, the first valve 4 and the second valve 5 are opened again, while the third valve 6 and the fourth valve 7 are closed. The pressurization device 1 delivers external water to the water-air mixing container 2. With the pressurization device 1 increasing the pressure, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantly, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water with a high microbubble content and obvious cleaning effect.

[0043] In one embodiment, the pressurizing device 1 is a booster pump. The microbubble generator provided in this embodiment uses one booster pump.

[0044] For example, the booster device 1 can be a diaphragm water pump.

[0045] In one embodiment, the first valve 4, the second valve 5, the third valve 6, and the fourth valve 7 are all solenoid valves.

[0046] In one embodiment, both the water-air mixing container 2 and the air replenishment and circulation container 3 can be sealed tanks.

[0047] In one embodiment, the microbubble generator further includes a power supply device for supplying power to the pressurizing device 1, the first valve 4, the second valve 5, the third valve 6, and the fourth valve 7.

[0048] For example, the power supply device can be a DC power supply device, which is safe and reliable.

[0049] In one embodiment, a fourth check valve 14 is provided between the second valve 5 and the first inlet of the water-air mixing container 2, and a fifth check valve 15 is provided between the third valve 6 and the water inlet of the air replenishment circulation container 3.

[0050] By setting the fourth check valve 14, water in the water-air mixing container 2 can be prevented from flowing back into the second valve 5, ensuring that the second valve 5 can work normally.

[0051] By setting the fifth check valve 15, water in the air replenishment circulation container 3 can be prevented from flowing back into the third valve 6, ensuring that the third valve 6 can work normally.

[0052] In one embodiment, the inlet of the booster device 1 is provided with a sixth check valve 16, which is located between the first valve 4 and the inlet of the booster device 1.

[0053] By setting the sixth check valve 16, water can be prevented from flowing back to the outside of the device.

[0054] In this embodiment, the first check valve 11, the second check valve 12, the third check valve 13, the fourth check valve 14, the fifth check valve 15, and the sixth check valve 16 all open and close automatically by fluid pressure and do not require electronic control.

[0055] In one embodiment, a pressure limiting valve 17 is provided between the booster device 1 and the sixth check valve 16. By providing the pressure limiting valve 17, it can be ensured that the inlet pressure of the booster device 1 does not exceed its operating range.

[0056] In one embodiment, the outlet of the water-air mixing container 2 is provided with a fifth valve 8.

[0057] Under normal operating conditions, the fifth valve 8 is normally open. The fifth valve 8 can also be a solenoid valve.

[0058] In one embodiment, a pressure relief valve 18 is provided on the top of the water-air mixing container 2. By providing the pressure relief valve 18, the water-air mixing container 2 can be protected. When the pressure inside the water-air mixing container 2 exceeds a certain limit, the pressure relief valve 18 can release the internal pressure, preventing excessive pressure inside the water-air mixing container 2 from causing an accident, thus improving safety performance.

[0059] In one embodiment, see Figure 1 As shown, the microbubble generator also includes a control device 21, which is used to control the opening and closing of the pressurization device 1, the first valve 4, the second valve 5, the third valve 6, the fourth valve 7, and the fifth valve 8.

[0060] For example, the control device 21 is a microcontroller unit (MCU).

[0061] It should be noted that the control device 21 is existing technology, and its structure will not be described in detail.

[0062] See Figure 1 As shown, the microbubble generator also includes a housing 19, a pressurizing device 1, a water-air mixing container 2, a gas replenishment and circulation container 3, a control device 21, and various solenoid valves and check valves, all of which are installed inside the housing 19.

[0063] A power button 22 is provided on the outside of the housing 19, and the power button 22 is connected to the circuit board in the control device 21.

[0064] This embodiment also provides a water outlet device, including a microbubble water outlet terminal 20 and a microbubble generator provided in this embodiment. The microbubble water outlet terminal 20 is connected to the water outlet of the water-air mixing container 2.

[0065] The water outlet device provided in this embodiment, by using the microbubble generator provided in this embodiment, can achieve pressurization and air replenishment functions without using an air pump, increasing the dissolved oxygen content in the water in the water-air mixing container 2, and reducing energy consumption and noise. In use, the first valve 4 and the second valve 5 are opened, and the pressurization device 1 delivers external water to the water-air mixing container 2. With the increased pressure from the pressurization device 1, the air and water in the water-air mixing container 2 can be fully mixed, increasing the dissolved oxygen content in the water. Because the microbubble water outlet terminal 20 is equipped with an aerator, when water passes through the aerator, the pressure decreases instantaneously, reducing the solubility of oxygen in the water. The oxygen is released and decomposed into tiny microbubbles, producing microbubble water with a high microbubble content and a significant cleaning effect.

[0066] During this process, the air in the water-air mixing container 2 gradually decreases, and the liquid level gradually rises. When the liquid level rises to a high level, the second valve 5 is closed and the third valve 6 is opened. At this time, external water enters the air replenishment circulation container 3 through the pressurization device 1, causing the liquid level in the air replenishment circulation container 3 to rise. This forces the air in the air replenishment circulation container 3 to be forced into the water-air mixing container 2 through the first check valve 11 from the air outlet of the air replenishment circulation container 3, replenishing the water-air mixing container 2 with air. At the same time, as the pressurization device 1 increases the pressure in the water-air mixing container 2, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the water outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

[0067] For example, the microbubble water outlet terminal 20 can be a shower head, kitchen faucet, or basin faucet.

[0068] It should be noted that the structure and working principle of the aerator are existing technologies and will not be described in detail here.

[0069] It should be understood that the microbubble water, the water in the water-air mixing container, and the water in the air replenishment and circulation container in this embodiment can be tap water, purified water, or liquids containing other components (e.g., essential oils, detergents).

[0070] This embodiment also provides a control method for a microbubble generator, including the following steps:

[0071] Open the first valve 4 and the second valve 5, and the pressurization device 1 delivers external water to the water-air mixing container 2 so that the air and water in the water-air mixing container 2 are mixed. The mixed water enters the microbubble water outlet terminal 20 from the outlet of the water-air mixing container 2 to form microbubble water.

[0072] The liquid level in the water-air mixing container 2 is obtained. When the liquid level reaches the high level, the second valve 5 is closed and the third valve 6 is opened. The pressurization device 1 delivers external water to the air replenishment circulation container 3 so that the air in the air replenishment circulation container 3 is forced into the water-air mixing container 2 through the first check valve 11. After the water and air in the water-air mixing container 2 are mixed, they enter the microbubble water outlet terminal 20 from the outlet of the water-air mixing container 2 to form microbubble water.

[0073] The control method for the microbubble generator provided in this embodiment controls the connection between the pressurizing device 1, the water-air mixing container 2, and the air replenishment circulation container 3 by controlling the opening and closing of the first valve 4, the second valve 5, and the third valve 6. This achieves pressurization and air replenishment without using an air pump, increasing the dissolved oxygen content in the water within the water-air mixing container 2 and reducing energy consumption and noise. In implementation, the outlet of the water-air mixing container 2 is connected to the microbubble water outlet terminal 20. The first valve 4 and the second valve 5 are opened, and the pressurizing device 1 delivers external water to the water-air mixing container 2. With the increased pressure from the pressurizing device 1, the air and water in the water-air mixing container 2 mix thoroughly, increasing the dissolved oxygen content. As the pressure decreases instantaneously through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water with a high microbubble content and a significant cleaning effect.

[0074] During this process, the air in the water-air mixing container 2 gradually decreases, and the liquid level gradually rises. When the liquid level rises to a high level, the second valve 5 is closed and the third valve 6 is opened. At this time, external water enters the air replenishment circulation container 3 through the pressurization device 1, causing the liquid level in the air replenishment circulation container 3 to rise. This forces the air in the air replenishment circulation container 3 to be forced into the water-air mixing container 2 through the first check valve 11 from the air outlet of the air replenishment circulation container 3, replenishing the water-air mixing container 2 with air. At the same time, as the pressurization device 1 increases the pressure in the water-air mixing container 2, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the water outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

[0075] The control method for the microbubble generator provided in this embodiment is applied to the microbubble generator provided in this embodiment. Specifically, see [link to documentation]. Figure 5 As shown, the control method for the microbubble generator provided in this embodiment includes the following steps:

[0076] In step S102, the first valve 4 and the second valve 5 are opened, and the pressurization device 1 delivers external water to the water-air mixing container 2 so that the air and water in the water-air mixing container 2 are mixed. The mixed water enters the microbubble water outlet terminal 20 from the outlet of the water-air mixing container 2 to form microbubble water.

[0077] It should be noted that before step S102, the method also includes the step of installing the microbubble water outlet terminal 20 at the outlet of the water-air mixing container 2.

[0078] With the first valve 4 and the second valve 5 open, and the third valve 6 and the fourth valve 7 closed, the pressurizing device 1 delivers external water to the water-air mixing container 2. As the pressurizing device 1 increases the pressure, the air and water in the water-air mixing container 2 can be fully mixed, increasing the dissolved oxygen content in the water. Through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, reducing the solubility of oxygen in the water. The oxygen is released and decomposed into tiny microbubbles, producing microbubble water with a high microbubble content and a significant cleaning effect.

[0079] See Figure 2 As shown, at the beginning of step S102, the liquid levels in both the water-air mixing container 2 and the air replenishment and circulation container 3 are below the high level. During step S102, the air in the water-air mixing container 2 gradually decreases, and the liquid level gradually rises.

[0080] Step S104: Obtain the liquid level in the water-air mixing container 2. When the liquid level reaches the high level, close the second valve 5 and open the third valve 6. The pressurization device 1 delivers external water to the air replenishment circulation container 3 so that the air in the air replenishment circulation container 3 is forced into the water-air mixing container 2 through the first check valve 11. After the water and air in the water-air mixing container 2 are mixed, they enter the microbubble water outlet terminal 20 from the outlet of the water-air mixing container 2 to form microbubble water.

[0081] In step S104, the liquid level sensor acquires the liquid level in the water-air mixing container 2 in real time, see [link to relevant documentation]. Figure 3As shown, when the liquid level in the water-air mixing container 2 rises to a high level, the high liquid level probe 9 detects this signal. The control device 21 closes the second valve 5 and opens the third valve 6. At this time, external water enters the air replenishment circulation container 3 through the pressurization device 1, causing the liquid level in the air replenishment circulation container 3 to rise. This forces the air in the air replenishment circulation container 3 to be forced into the water-air mixing container 2 through the first check valve 11 from the air outlet of the air replenishment circulation container 3, replenishing the water-air mixing container 2 with air. At the same time, as the pressurization device 1 increases the pressure in the water-air mixing container 2, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the water outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

[0082] In one embodiment, see Figure 6 As shown, after the pressurization device 1 delivers external water to the air replenishment and circulation container 3, it also includes:

[0083] Step S106: Obtain the liquid level in the gas replenishment circulation container 3. When the liquid level reaches the high level, close the first valve 4 and the third valve 6, and open the second valve 5 and the fourth valve 7. The pressurization device 1 transports the water in the gas replenishment circulation container 3 to the water-air mixing container 2. Outside air enters the gas replenishment circulation container 3 through the third check valve 13.

[0084] Specifically, after step 104, that is, after the pressurizing device 1 delivers external water to the air replenishment circulation container 3, so that the air in the air replenishment circulation container 3 is forced into the water-air mixing container 2 through the first check valve 11, see [link to relevant documentation]. Figure 4 As shown, when the liquid level in the gas replenishment circulation container 3 rises to a high level, the high liquid level probe 9 detects this signal. The control device 21 closes the first valve 4 and the third valve 6, and opens the second valve 5 and the fourth valve 7. Under the action of the pressurizing device 1, the water in the gas replenishment circulation container 3 is drawn into the water-air mixing container 2 through the second check valve 12, and the liquid level in the gas replenishment circulation container 3 drops accordingly. At this time, the third check valve 13 opens under the action of negative pressure in the gas replenishment circulation container 3, and outside air is drawn into the gas replenishment circulation container 3, thereby replenishing air into the gas replenishment circulation container 3 to ensure that the microbubble generator can work continuously.

[0085] In one embodiment, see Figure 6 As shown, after the pressurization device 1 transports the water in the air replenishment circulation container 3 to the water-air mixing container 2, it also includes:

[0086] Step S108: Obtain the liquid level in the gas replenishment circulation container 3. When the liquid level is low, re-execute the operation of opening the first valve 4 and the second valve 5, and the pressurization device 1 delivers the external water source to the water-air mixing container 2.

[0087] Specifically, after step S106, when the liquid level in the air replenishment circulation container 3 drops to a low level, the low liquid level probe 10 detects this signal, and the control device 21 reopens the first valve 4 and the second valve 5, while closing the third valve 6 and the fourth valve 7. The pressurization device 1 delivers external water to the water-air mixing container 2. With the pressurization device 1 increasing the pressure, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Microbubble water is generated through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20.

[0088] When the liquid level in the water-air mixing container 2 rises to a high level, the high liquid level probe 9 detects this signal. The control device 21 closes the second valve 5 and opens the third valve 6. At this time, external water enters the air replenishment circulation container 3 through the pressurization device 1, causing the liquid level in the air replenishment circulation container 3 to rise. This forces the air in the air replenishment circulation container 3 to be forced into the water-air mixing container 2 through the first check valve 11 from the air outlet of the air replenishment circulation container 3, replenishing the water-air mixing container 2 with air. At the same time, as the pressurization device 1 increases the pressure in the water-air mixing container 2, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Through the water outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20, the pressure decreases instantaneously, the solubility of oxygen in the water decreases, and the oxygen is released and decomposed into tiny microbubbles, producing microbubble water.

[0089] When the liquid level in the gas replenishment circulation container 3 reaches the high level, the first valve 4 and the third valve 6 are closed, and the second valve 5 and the fourth valve 7 are opened. The pressurization device 1 transports the water in the gas replenishment circulation container 3 to the water-air mixing container 2, and the outside air enters the gas replenishment circulation container 3 through the third check valve 13.

[0090] When the liquid level in the air replenishment circulation container 3 drops to a low level, the low liquid level probe 10 detects this signal. The control device 21 opens the first valve 4 and the second valve 5 again, while closing the third valve 6 and the fourth valve 7. The pressurization device 1 delivers external water to the water-air mixing container 2. With the pressurization device 1 increasing the pressure, the air and water in the water-air mixing container 2 can be fully mixed, and the dissolved oxygen in the water increases. Microbubble water is generated through the outlet of the water-air mixing container 2 and the microbubble water outlet terminal 20.

[0091] In other words, during the normal operation of the microbubble generator, the steps S102, S104, S106, and S108 are performed in a cyclical manner, so that the microbubble generator always maintains a high pressure and replenishes air in the water-vapor mixing container, and continuously generates microbubble water.

[0092] The microbubble water outlet terminal 20 can be a shower or a faucet. When the microbubble water outlet terminal is a shower, microbubble water can be dispensed through the shower for bathing, which has an excellent cleaning effect on the skin. When the microbubble water outlet terminal is a faucet, microbubble water can be dispensed through the faucet to wash fruits and vegetables or clean the sink, which has a good cleaning effect on dirt.
