[0029] With the gradual development of society, people's quality of life is constantly improving, and they are paying more and more attention to health issues. Since the diameter of micro-nano bubbles is very small, they have good effects on vegetable washing, healthy bathing, wastewater treatment, sterilization, etc., and are widely used in aquaculture, agriculture, forestry, medical industry and other fields.

[0030] In the prior art, a Chinese utility model patent application with publication number CN211837316U discloses a micro-nano bubble bubbler, comprising: a shell, provided with a liquid pressurization hole and an air inlet hole; a filter screen installed in the shell, blocking the outside of the liquid pressurization hole; an air control plate placed in the shell, provided with a liquid inlet channel connected to the liquid pressurization hole; and a cutting structure installed in the shell, one end of the cutting structure abuts against the air control plate, and forms a gas-liquid accommodating space, the other end of the cutting structure is provided with a gas-liquid outlet, and the cutting structure is provided with a cutting net near the gas-liquid outlet, and the bubbles in the liquid are cut by the cutting net to form micro-nano bubbles. In the process of use and installation, since the micro-nano bubbler contains structures such as a shell, an air control plate, a cutting structure and a cutting net, multiple components need to be assembled to obtain the bubbler, which is easy to cause unsatisfactory foaming effect due to irregular assembly, and multiple components lead to a high cost of the bubbler.

[0031] Based on this, the present specification embodiment proposes a micro-nano bubbler: Figures 1 to 3 As shown, it includes a shell 1, a water inlet hole 2 is opened on the side of the shell 1 facing the water inlet end, the water inlet is connected to a pressurizing hole 3, the aperture of the pressurizing hole 3 is smaller than the aperture of the water inlet hole 2, and the side of the pressurizing hole 3 away from the water inlet hole 2 is connected to a mixing hole 4, and the aperture of the mixing hole 4 is larger than the aperture of the pressurizing hole 3.

[0032] The diameter of the mixing hole 4 at one end facing the water inlet hole 2 is greater than or equal to the diameter of the mixing hole 4 at one end facing away from the water inlet hole 2 .

[0033] Since water supply pipelines such as municipal pipelines themselves contain a certain amount of air and pressure, the embodiment of the present application pressurizes and mixes the air in the water supply pipeline through the pressurization hole 3 and the mixing hole 4 to generate micro-nano bubbles. The structure is simple and all are integrated in the shell 1, which eliminates the process of assembling multiple components and reduces the cost of the foamer.

[0034] In the embodiment of the present application, the diameter of the mixing hole is 1.2-2 times the diameter of the pressure hole, the diameter of the pressure hole is 3 mm, and the diameter of the mixing hole is 3.5 mm. In other embodiments, the diameter of the pressure hole is 3 cm, and the diameter of the mixing hole is 3.5 cm.

The end of the buffer portion 5 with a larger aperture is connected to the water inlet hole 2, and the end of the buffer portion 5 with a smaller aperture is connected to the pressurizing hole 3. The water flow in the water supply pipeline enters the pressurizing hole 3 through the buffer portion 5, avoiding collision with the outer wall of the pressurizing hole 3, increasing the flow rate of the water flow, and better transmitting the pressure to the pressurizing hole 3 to pressurize the water flow and air in the pressurizing hole 3.

[0036] In the embodiment of the present application, the mixing hole 4 is cylindrical, the diameter of the mixing hole is larger than the diameter of the pressurizing part, and the diameter of the mixing hole is smaller than the water inlet hole 2. A certain pressure can be maintained during the mixing process to fully mix the micro-nano bubbles with the water flow.

[0037] In the embodiment of the present application, one end of the mixing hole 4 away from the pressurizing hole 3 is connected to a bell mouth 6 .

[0038] In another embodiment, the shell 1 includes an upper shell 7 and a lower shell 8, the water inlet hole 2, the pressurization hole 3 and the buffer part 5 are arranged in the upper shell 7, the mixing hole and the bell mouth 6 are arranged in the lower shell 8, and the upper shell 7 and the lower shell 8 are connected by threads.

[0039] The upper shell 7 is provided with an annular groove 9, the lower shell 8 is integrally provided with an annular protrusion 10, the pressurizing hole 3 is arranged in the middle position of the annular groove 9, the mixing hole 4 is arranged in the middle position of the annular protrusion 10, and the annular protrusion 10 can be placed in the annular groove 9 to better seal the mixing hole 4.

[0040] In the embodiment of the present application, the opening of the mixing hole 4 close to the pressurizing hole 3 is larger than the opening of the mixing hole 4 away from the pressurizing hole 3, and the diameter of the mixing hole 4 is larger than the diameter of the pressurizing hole 3 and smaller than the diameter of the water inlet 2. The diameter of the water inlet of the mixing hole 4 is larger than the diameter of the water outlet, which can effectively pressurize and mix the air and water flow, and is convenient for mold opening and manufacturing.

[0041] One or both ends of the shell 1 are provided with an external thread structure. One end of the shell 1 is provided with an external thread structure which can be directly fixed on the water outlet pipe to release micro-nano bubbles. Both ends of the shell 1 are provided with external threads. One end of the shell 1 can be connected to a pressure water supply device, and the other end is connected to the water outlet pipe, acting as a connecting device.

[0042] In this specification, the same or similar parts between the various embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the embodiments described later, the description is relatively simple, and the relevant parts can be referred to the partial description of the previous embodiments.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
