[0022] Figure 1 It is a schematic structural diagram of the micro-nano bubble generating device of the present invention. Detailed Embodiments

[0023] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0024] Refer to Figure 1, the present invention provides a micro-nano bubble generating device, which is used to solve the problem that the water output of the existing micro-bubble generator is small and cannot meet the use requirements of large water output or other industrial scenarios. Since the existing micro-bubble generator can achieve the gas-liquid dissolution effect only for a fixed water output, when it is directly applied to the case of large water output, the mixing and generation efficiency of micro-bubbles is low and cannot meet the use requirements. The micro-nano bubble generating device of the present invention combines a gas-liquid mixing pump and a gas pump. The gas pump provides gas with a set pressure for the gas-liquid mixing pump, and by controlling the gas to be injected into the liquid in a certain high-pressure state, the required micro-nano bubbles are generated. On the one hand, the gas-liquid mixing and generation efficiency is high, and on the other hand, it can meet the use requirements of large water output or other industrial scenarios. The micro-nano bubble generating device of the present invention has the advantages of simple structure, good gas-liquid dissolution effect, and high mixing and generation efficiency. The micro-nano bubble generating device of the present invention will be described below with reference to the accompanying drawings.

[0025] Refer to Figure 1 , which shows a schematic structural diagram of the micro-nano bubble generating device of the present invention. The structure of the micro-nano bubble generating device of the present invention will be described below in conjunction with Figure 1 , and the structure of the micro-nano bubble generating device of the present invention will be described.

[0026] As Figure 1 shown, the micro-nano bubble generating device 20 of the present invention includes a gas-liquid mixing pump 21 and a gas pump 22. The gas-liquid mixing pump 21 has a liquid inlet 211, a liquid outlet 213, and a gas inlet 212. Liquid is input into the gas-liquid mixing pump 21 through the liquid inlet 211; the gas pump 22 is connected to the gas inlet 212 of the gas-liquid mixing pump 21, and gas with a set pressure is transported to the gas-liquid mixing pump 21 through the gas pump 22. The gas is pressed into the gas-liquid mixing pump 21 and mixed with the liquid in the gas-liquid mixing pump 21 to form micro-nano bubbles in the liquid, and the liquid mixed with micro-nano bubbles is output through the liquid outlet.

[0027] The liquid input into the gas-liquid mixing pump 21 is preferably water, and the gas input into the gas-liquid mixing pump 21 is preferably air. When using the micro-nano bubble generating device of the present invention, the liquid inlet 211 is connected to a water source, and water is pumped into the gas-liquid mixing pump 21 through the operation of the gas-liquid mixing pump 21 to achieve mixing with the gas. The micro-nano bubble generating device 20 of the present invention injects external air into the water in the gas-liquid mixing pump 21 in a high-pressure state through the operation of the gas pump 22, thereby generating micro-nano bubbles in the water, and the liquid mixed with micro-nano bubbles is output through the liquid outlet 213.

[0028] The set pressure of the gas is a set pressure value. By selecting different pressure values, micro-nano bubbles with different particle size ranges can be obtained. Therefore, the pressure value of the gas injected into the liquid can be set or selected according to actual needs.

[0029] In a specific embodiment of the present invention, the micro-nano bubble generating device 20 of the present invention further includes a gas storage tank 23 connected between the air inlet 212 and the air pump 22. A storage space for storing gas is formed inside the gas storage tank 23. The air pump 22 pumps external air into the gas storage tank 23. The pressure of the air is controlled by the air pump 22. The setting of the gas storage tank 23 can ensure the amount of air, so that the air can be continuously pressed into the gas-liquid mixing pump 21 to be mixed with the liquid.

[0030] Further, as Figure 1 shown, a drain port 231 is provided at the bottom of the gas storage tank 23, and a solenoid valve 241 for controlling the opening and closing of the drain port 231 is installed at the drain port. The solenoid valve 241 can detect whether there is water at the drain port 231 of the gas storage tank 23. If there is water, the solenoid valve 241 automatically opens the drain port 231 to drain the water, and then automatically closes the drain port 231 after draining.

[0031] In a specific embodiment of the present invention, an intake pipe 251 is connected between the air inlet 212 and the air pump 22, and a gas flow control valve 242 is installed on the intake pipe 251 near the air inlet 212. The amount of gas entering the gas-liquid mixing pump 21 is controlled by the gas flow control valve 242. Specifically, the amount of gas input into the gas-liquid mixing pump 21 can be selected according to the actual operating power of the gas-liquid mixing pump 21. After setting the intake air volume of the better gas, the intake air volume is controlled by adjusting the gas flow control valve 242.

[0032] Further, when the gas storage tank 23 is provided, the intake pipe 251 is connected between the air inlet 212 and the gas storage tank 23, and a ventilation pipe 254 is connected between the gas storage tank 23 and the air pump 22. Preferably, the ventilation pipe 254 is connected to the top of the gas storage tank 23, and the intake pipe 251 is connected to the side of the gas storage tank 23.

[0033] In a specific embodiment of the present invention, an intake pipe 251 is connected between the air inlet 212 of the gas-liquid mixing pump 21 and the air pump 22, and a first one-way valve 243 is installed on the intake pipe 251 near the air inlet 212. The first one-way valve 243 is used to control the flow direction of the gas, so that the gas can only flow into the gas-liquid mixing pump 21 and cannot flow back in the reverse direction. The first one-way valve 243 preferably is a gas one-way valve, which plays a role in preventing gas-liquid backflow.

[0034] In a specific embodiment of the present invention, a liquid inlet pipe 252 is connected to the liquid inlet 211 of the gas-liquid mixing pump 21, and a filter 26 is installed on the liquid inlet pipe 252. The liquid is filtered by the filter 26, and the filtered liquid is then transported into the gas-liquid mixing pump 21.

[0035] In a specific embodiment of the present invention, a liquid outlet pipe 253 is connected to the liquid outlet 213 of the gas-liquid mixing pump 21. A second check valve 244 is installed on the liquid outlet pipe 253, and this second check valve 244 functions to prevent gas-liquid backflow. Preferably, the second check valve 244 is a liquid check valve. The liquid outlet pipe 253 can be provided with multiple liquid outlet branches according to the applicable scenario.

[0036] In a specific embodiment of the present invention, a pressure sensor 27 is installed on the liquid outlet pipe 253 which is connected to the liquid outlet 213 of the gas-liquid mixing pump 21. The pressure sensor 27 is connected to the gas-liquid mixing pump 21 for control. The pressure sensor 27 is used to detect the pressure of the liquid outlet pipe 253. When the detected pressure reaches a certain range, the pressure sensor 27 controls the gas-liquid mixing pump 21 to close to avoid the gas-liquid mixing pump 21 from running under long-term load.

[0037] In a specific embodiment of the present invention, a mixing chamber is provided inside the gas-liquid mixing pump 21. The liquid inlet 211 is provided on the side of the mixing chamber, the gas inlet 212 is provided on the top of the mixing chamber, and the liquid outlet 213 is provided on the top of the mixing chamber.

[0038] The gas-liquid mixing pump 21 further includes a stirrer provided in the mixing chamber to mix the micro-nano bubbles and the liquid in the mixing chamber evenly. Preferably, the stirrer is a rotatable impeller, and the rotation of the impeller is used to stir the liquid and the micro-nano bubbles.

[0039] In a specific embodiment of the present invention, an air inlet nozzle is installed at the air inlet 212. The air inlet nozzle is provided with multiple air holes, and the aperture of the air holes is at the nano level. The orientations of the air holes are different, and the air holes are inclined. By using the provided air inlet nozzle, the gas can be injected into the liquid at a high speed in an inclined state and micro-nano bubbles can be formed quickly.

[0040] The working principle of the micro-nano bubble generating device of the present invention is as follows:

[0041] Turn on the gas-liquid mixing pump 21 and the air pump 22 to make them run. The gas-liquid mixing pump 21 sucks the liquid from the liquid inlet 211 into the mixing chamber, and the air pump 22 presses the air from the air inlet 212 into the mixing chamber, so that the air is mixed into the liquid at a set pressure to form micro-nano bubbles. Then, the micro-nano bubbles and the liquid are stirred by the rotation of the impeller in the mixing chamber to make the micro-nano bubbles and the liquid mix evenly, and then they are discharged through the liquid outlet 213.

[0042] The beneficial effects of the micro-nano bubble generating device of the present invention are as follows:

[0043] A gas pump provides gas with a certain pressure for the gas-liquid mixing pump, so that after the gas is mixed with the liquid in the gas-liquid mixing pump, micro-nano bubbles are formed in the liquid. In the prior art, the gas-liquid mixing pump sucks in air through its own negative pressure and mixes it with the liquid, and micron-sized bubbles are formed in the liquid. These micron-sized bubbles cannot achieve the good effects such as cleaning and sterilization of nano-sized bubbles. The micro-nano bubble generating device of the present invention has a simple structure and a large water output, and can meet the requirements of gas-liquid dissolution effect and changing application scenarios.

[0044] The present invention has been described in detail above in conjunction with the embodiments with reference to the drawings. Those of ordinary skill in the art can make various variations of the present invention according to the above description. Therefore, certain details in the embodiments should not constitute a limitation to the present invention, and the present invention will take the scope defined by the appended claims as the protection scope of the present invention.
