[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application. Figs. 1-3 A negative pressure type air intake nanometer generator, comprising: a shell body 6, a connector 13, a mounting seat 1 and a flow block 10; the shell body 6 is in a cylindrical structure, the shell body 6 is provided with a first air inlet hole 7, the inside of the shell body 6 is provided with a water collecting groove 16, a spraying cavity 18, and a spraying port 17 communicating the water collecting groove 16 and the spraying cavity 18; the connector 13 is connected to one end of the shell body 6 close to the water collecting groove 16, the connector 13 is used for connecting external equipment, and the connector 13 is provided with a water inlet 14; the mounting seat 1 is connected to one end of the shell body 6 close to the spraying cavity 18, the inside of the mounting seat 1 is provided with a mesh and a water outlet 19; the flow block 10 is arranged in the inside of the shell body 6, one side of the flow block 10 is provided with a second air inlet hole 15 communicating with the first air inlet hole 7, and the bottom of the flow block 10 is provided with an air pipe 8 and a water passing port 9, the air pipe 8 is inserted into the spraying port 17, the diameter of the air pipe 8 is smaller than that of the spraying port 17, and the water passing port 9 communicates with the water collecting groove 16.

[0021] The water with pressure enters from the water inlet 14, enters the water collecting groove 16 through the water passing port 9 of the flow block 10, and is sprayed into the spraying cavity 18 through the spraying port 17. When the high-pressure water is sprayed into the spraying cavity 18 through the spraying port 17, the pressure energy in the inside of the flow block 10 is released to form a negative pressure. Under the action of the negative pressure, air enters from the first air inlet hole 7, passes through the second air inlet hole 15, comes out of the air pipe 8, and is automatically mixed with water in the spraying cavity 18. Then, the micro-nano bubble mixed liquid is formed by the cutting of the mesh and comes out of the water outlet 19 for use.

[0022] The negative pressure type air intake nanometer generator has a simple structure, adopts a negative pressure type air intake method, omits the traditional air-liquid mixing pump which is a key component, simplifies the overall structure of the nanometer generator, and reduces the manufacturing cost and maintenance difficulty. The problems that the existing nanometer generator needs to rely on the air-liquid mixing pump, the structure of the nanometer generator is complex, and the generation quality of the nanometer bubbles may be affected due to the failure of the air-liquid mixing pump are solved.

[0023] In some embodiments, the mesh includes a first mesh 2 and a second mesh 4, and the inside of the mounting seat 1 is further provided with a first mesh pressing ring 3 and a second mesh pressing ring 5, and the first mesh pressing ring 3 and the second mesh pressing ring 5 are used for supporting the first mesh 2 and the second mesh 4.

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application. Figs. 2-3, by setting the first mesh 2 and the second mesh 4, the contact area between water and gas is increased, the water vapor mixture from the injection chamber 18 is better cut, which helps to further refine the bubbles and improve the generation efficiency and quality of nanobubbles. The first mesh 2 and the second mesh 4 ensure that the first mesh 2 and the second mesh 4 remain stable in structure under the impact of high-pressure water flow and gas, and do not shift or deform, thereby ensuring the refining effect of the first mesh 2 and the second mesh 4 on nanobubbles. When the first mesh 2 or the second mesh 4 needs to be cleaned or replaced, the user only needs to simply disassemble the mounting seat 1, the first mesh 2 and the second mesh 4, and then replace them. The design of the mounting seat 1, the first mesh 2 and the second mesh 4 makes the operation more convenient and fast.

[0025] In some embodiments, the outer side of the overflow block 10 is provided with a gas groove 12 and a sealing groove, and the sealing groove is provided with a sealing ring 11. The sealing groove is provided with two sealing grooves, respectively located on both sides of the gas groove 12, and the gas groove 12 is in communication with the first gas inlet hole 7 and the second gas inlet hole 15.

[0026] Referring to Fig. 3 , the gas groove 12 serves as a path for gas transmission and is in direct communication with the first gas inlet hole 7 and the second gas inlet hole 15, ensuring that the air outside the shell body 6 can smoothly enter the inside of the injection chamber 18 and participate in the process of gas-liquid mixing. In addition, the arrangement of the gas groove 12 facilitates the communication between the first gas inlet hole 7 and the second gas inlet hole 15, without the need for the first gas inlet hole 7 and the second gas inlet hole 15 to be aligned. The arrangement of the sealing groove and the sealing ring 11, on the one hand, enhances the sealing effect between the overflow block 10 and the shell body 6, avoiding the penetration of water flow into the gas groove 12; on the other hand, when high-pressure water passes through the injection port 17 and is injected into the injection chamber 18, the local negative pressure of the gas groove 12 is maintained, so that the external gas enters the second gas inlet hole 15 more quickly.

[0027] In some embodiments, the water collecting groove 16 is a conical structure, and the tip of the water collecting groove 16 faces the injection port 17.

[0028] Referring to Fig. 3 , the conical structure of the water collecting groove 16 can effectively guide the water flow from a wider inlet to a narrower injection port 17, thereby forming an accelerating flow trend, generating a higher flow rate and a local low pressure area at the injection port 17, and further promoting the inhalation and dispersion of gas. Compared with the flat-shaped water collecting groove 16, the conical structure can reduce the turbulence and vortex phenomenon in the water flow, ensure that the water flow passes through the injection port 17 more smoothly, and be beneficial to the generation of uniform and stable nanobubbles.

[0029] In some embodiments, the injection chamber 18 is a conical structure, and the tip of the injection chamber 18 faces the injection port 17.

[0030] Referring to Fig. 3, the conical structure of the spray cavity 18 can effectively guide the water flow from the narrow spray port 17 to the wide water outlet 19, and the water flow sprayed from the narrow spray port 17 can quickly spread to cover a larger area, so that the water containing nano bubbles is uniformly distributed on the mesh, thereby improving the treatment effect of the mesh.

[0031] In some embodiments, the shell body 6 and the joint 13 are connected in a threaded manner, and the shell body 6 and the mounting seat 1 are also connected in a threaded manner.

[0032] Referring to Fig. 3 The threaded connection is a simple and efficient connection method that can be completed without tools, thereby shortening the assembly time; when the inside of the shell body 6 needs to be cleaned, the overflow block 10 needs to be replaced, or the mesh needs to be replaced, the user can easily disassemble the shell body 6 from the joint 13 or the mounting seat 1 through a simple screwing operation, thereby simplifying the maintenance process.

[0033] In some embodiments, the joint 13 has a stepped structure, and the outer side is provided with threads.

[0034] Referring to Fig. 3 The stepped structure makes each part of the joint 13 more intuitive, so that the user can quickly identify the correct assembly direction and position, thereby simplifying the installation process. The threads provided on the outer side of the joint 13 facilitate the connection of external equipment, so that high-pressure water enters the joint 13 from the water inlet 14.
