[0032] Example 1

[0033] like Figure 1-4 As shown, the utility model provides a micro-bubble bubbler, comprising an inner core 1, an auxiliary filter net 2 and a support net 3;

[0034] The front end of the support net 3 is a mesh surface, the front end of the inner core 1 is located inside the support net 3, and the auxiliary filter net 2 is located between the front end of the inner core 1 and the front end of the support net 3;

[0035] The inner core 1 is a main component for processing water flow and generating micro bubbles; a circle of gas guide grooves 1-3 are arranged on the outer surface of the inner core 1; a plurality of air inlets 1-1 are provided on the outer surface of the inner core 1 from the front end surface of the inner core 1 to the gas guide grooves 1-3, and the air inlets 1-1 are tapered holes connected to the gas guide grooves 1-1, and the large diameter end is located on the front end surface of the inner core 1; the gas guide grooves 1-3 are connected to the air outside the bubbler, and form a gas passage R1 with the air inlet 1-1; the tapered air inlet 1-1 can form a larger airflow, and the large diameter end can form a larger contact area with water;

[0036] The inner core 1 is provided with a plurality of micro-bubble jet holes 1-2 extending from the front end surface to the rear end surface. The micro-bubble jet holes 1-2 include a conical section and a straight section along the axial direction. The large diameter end of the conical section is located at the front end surface of the inner core 1. The micro-bubble jet holes 1-2 form a water flow path R2.

[0037] The bottom of the support net 3 is fixedly installed on the outer side of the inner core 1; there is a gap between the auxiliary filter net 2 and the front end surface of the inner core 1, and after being impacted by the water flow flowing out of the micro-bubble jet holes 1-2, a cavity M1 can be formed between the auxiliary filter net 2 and the front end surface of the inner core 1 (the auxiliary filter net 2 is impacted by the high-speed water flow and is adsorbed to the front end mesh surface of the support net 3, so that the auxiliary filter net 2 and the front end surface of the inner core 1 are not connected to each other, forming the cavity M1 that can connect the gas passage R1 and the water flow passage R2), and the gas passage R1 and the water flow passage R2 are both connected to the The cavity M1 is connected, and when water flows through the micro-bubble jet holes 1-2 at high speed, negative pressure can be generated around it due to the high-speed water flow. At the same time, the air outside the bubbler is sucked into the cavity M1 through the gas passage (because the water flow rate out of the end of the bubbler is extremely high, negative pressure will be formed around it to automatically suck in the gas). The gas can form an air film at the exit of the cavity M1. After the water flows through the micro-bubble jet holes 1-2, the high-speed water flow can collide with the air film to produce a large number of microbubbles. The auxiliary filter 2 can cut the generated microbubbles to form more microbubbles, thereby dissipating energy and reducing noise for the high-speed water flow.

[0038] Furthermore, an angle β between an inner side wall of the air inlet 1 - 1 and a central axis of the air inlet 1 - 1 is 1 to 30°.

[0039] Furthermore, the inner core 1 is provided with 3 to 12 air inlets 1 - 1 .

[0040] Furthermore, the conical sections of the air inlet 1 - 1 and the micro-bubble jet hole 1 - 2 are both conical holes.

[0041] Furthermore, the diameter φ of the straight section of the micro-bubble jet hole 1-2 is 0.1-5 mm; the angle α between the inner side wall of the tapered section of the micro-bubble jet hole 1-2 and the central axis of the micro-bubble jet hole 1-2 is greater than 0° and less than or equal to 30°.

[0042] Furthermore, a snap-fit ​​structure that can be installed in the gas guide groove 1-3 is provided at the bottom of the support net 3, the front end of the inner core 1 is located in the support net 3, the snap-fit ​​knot is snapped with the gas guide groove 1-3, and there is a gap between the snap-fit ​​structure and the gas guide groove 1-3, which can ensure that the inner core 1 and the support net 3 are fixedly connected to each other to prevent the inner core 1 from slipping into the support net 3, while ensuring that a certain gap is maintained between the inner core 1 and the auxiliary filter net 2 to form the cavity.

[0043] Furthermore, 1-3 layers of the auxiliary filter net 2 with a mesh size of 40 to 500 (selectable according to different needs) are arranged between the inner core 1 and the support net 3. The auxiliary filter net 2 is used to organize the water flow and make the micro-bubbles generated in the water flow more uniform, and can cooperate with the air inlet of the inner core 1 to further enhance the uniformity and quantity of the micro-bubble water, so that the micro-bubble water can better play the role of cleaning and removing chemical residues.

[0044] Furthermore, the inner core 1 and the support net 3 are both cylindrical structures, and the auxiliary filter net 2 is a circular sheet structure.

[0045] Furthermore, when processing the micro-bubble bubbler described in this application:

[0046] The specific value of the diameter φ of the straight segment of the micro-bubble jet hole 1-2 is related to the water pressure P and flow rate Q of the water flowing into the micro-bubble jet hole 1-2, the specific value of the length L1 of the straight segment of the micro-bubble jet hole 1-2 is related to the water pressure P, flow velocity V and flow rate Q of the water flowing into the micro-bubble jet hole 1-2, and the length L2 of the tapered segment of the micro-bubble jet hole 1-2 is related to the value of α and the water pressure P and flow rate Q of the water flowing into the micro-bubble jet hole 1-2;

[0047] The specific value of the diameter U of the small diameter end of the air inlet 1-1 is related to the flow velocity V and flow rate Q of the water flowing into the micro-bubble jet hole 1-2;

[0048] The specific values ​​of φ, L1, L2 and U are also related to the size of the micro-bubble bubbler.

[0049] Furthermore, it also includes a sleeve, and the assembled inner core 1, the auxiliary filter net 2 and the support net 3 can be installed in the sleeve with openings at both ends; the front end of the support net 3 is installed in the sleeve toward the opening on one side of the sleeve, and the other side of the sleeve is provided with an internal thread structure, so that the micro-bubble bubbler can be installed on a faucet or connecting pipe with a threaded structure.

[0050] When using the micro-bubble bubbler described in the utility model, the bubbler originally provided with the faucet is removed and replaced with the micro-bubble bubbler described in the present application. During the operation of the bubbler, no position and shape changes will occur and no additional substances will be generated. By arranging a gas guide groove and an air inlet on the inner core, more air can be added to the outlet of the jet hole of the inner core. Together with the jet hole (sprayed water), the amount of micro-bubbles generated can be increased, making the micro-bubbles denser and more numerous, and the water flow more stable, thereby improving the strong cleaning power and obtaining better skin protection and sterilization and antibacterial effects.

[0051] In addition to household use, the micro-bubble aerator described in the utility model is also applicable to other faucets and shower heads in public water rooms such as baths, schools, factories, railway stations, office buildings, etc.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
