Before the detailed description, it should be noted that similar elements are designated by the same reference numerals.

Referring to FIG. 1 , which is a preferred embodiment of the micro-bubble generator of the present invention, the micro-bubble is generated by the passage of the water supply. As shown in FIG. 1 , this embodiment is installed on the faucet 10 , but in actual use, it may also be installed on the shower head, which is not limited to what is disclosed in this embodiment.

Referring to FIG. 2 , the micro-bubble generator includes a sleeve 2 , a first mesh 3 , a pressure sheet 4 , a second mesh 5 , a plurality of gaskets 6 , and an end cap 7 .

2 and 3, the sleeve 2 includes a front joint area 21, a rear joint area 22 integrally extending from the front joint area 21, a flow channel 23 axially penetrating the front joint area 21, An accommodating space 24 surrounding the rear joint area 22 and communicating with the flow channel 23 , and an air channel 25 radially penetrating the front joint area 21 and communicating with the flow channel 23 .

Wherein, as shown in FIG. 2 , the first mesh sheet 3 is formed with a plurality of cutting marks 31 , and each cutting mark 31 extends radially from the periphery of the first mesh sheet 3 toward the center point. It should be noted that, the number of the cutting marks 31 on the first mesh sheet 3 may be two, four, eight, or even more. In actual implementation, the number of the first mesh sheets 3 may also be plural, and the number of the cutting marks 31 may be the same or different. In addition, the first mesh 3 and the second mesh 5 are cut from stainless steel mesh. The pressing piece 4 is also cut from a stainless steel sheet, and then through holes 41 are formed at a plurality of intervals by punching.

As shown in FIG. 3 , the flow channel 23 has a small aperture section 231 , a medium aperture section 232 connected to the small aperture section 231 , and a large aperture section 233 connected to the medium aperture section 232 . The aperture of the large aperture section 233 is gradually increasing in the direction away from the medium aperture section 232, and the maximum diameter of the large aperture section 233 is at least twice the maximum diameter of the medium aperture section 232. The air passage 25 is connected to the outside and the The middle aperture section 232 .

2 and 3 , in this embodiment, the pressure sheet 4 , the first mesh sheet 3 , the second mesh sheet 5 , and the gasket 6 are sequentially stacked on the In the accommodating space 24 , the end cap 7 is finally combined with the end of the rear joint area 22 to block, so as to prevent the aforementioned components from falling off from the accommodating space 24 . It should be noted that the stacking relationship of the above-mentioned elements is only one aspect of the preferred embodiment, and the number and stacking sequence of the elements can be adjusted according to the actual use situation, which is not limited thereto.

The front engaging area 21 is formed with an external thread, the rear engaging area 22 is formed with an internal thread, and the end cap 7 is formed with an external thread so as to be screwed with the rear engaging area 22 . After the pressure sheet 4 , the first mesh sheet 3 , the second mesh sheet 5 , and the gasket 6 are stacked in the accommodating space 24 according to the above description, the end cover 7 is screwed to the sleeve 2 . The rear bonding area 22 is completed, that is, the assembling action is completed. In this embodiment, the end cap 7 has a hollow annular cap body 71 and a filter 72 disposed on the cap body 71 through which water can flow. A concave portion 711 is formed on the side of the cover body 71 facing the sleeve 2 for accommodating the filter piece 72 , so that the filter piece 72 and the cover body 71 are coplanar. Two operating holes 712 (shown in FIG. 1 ) are formed on the other side of the cover body 71 with symmetrical positions. Therefore, when the cover body 71 is locked or disassembled, a tool can be inserted into the two operation holes. 712, improving the convenience of assembly. The cover body 71 is of annular design, so that the components will not fall out of the accommodating space 24, but will not block the flow of water.

In actual use, the sleeve 2 is directly connected to the faucet by using the front engaging area 21 .

After the water flow enters the accommodating space 24 , it will first pass through the pressure sheet 4 . In this embodiment, the pressure sheet 4 has four through holes 41 with a diameter of 0.1 mm. When the water flows through the pressure sheet 4 When the water flow can only flow through the through hole 41, when the water flow path is greatly reduced, the pressure of the water flow will increase to achieve the effect of pressurization. Wherein, the number of the through holes 41 of the pressing sheet 4 and the size of the apertures thereof can be changed according to different installation environments and conditions, and are not limited to those disclosed in this embodiment.

After the water flow passes through the pressure sheet 4, it flows through the first mesh sheet 3. Since the first mesh sheet 3 has a dense mesh structure, a large number of micro-bubbles will be generated when the water flow passes through. At the same time, the first mesh sheet 3 is formed with cutting marks 31, so that the water flow can easily pass through. The water flow then passes through the second mesh sheet 5. The second mesh sheet 5 also has a dense mesh structure, so that a large number of micro-bubbles can be generated when the water flow passes through.

In addition, it should be noted that the maximum diameter of the large aperture section 233 of the flow channel 23 is at least twice the maximum diameter of the medium aperture section 232. Therefore, when the water flows into the large aperture section 233, due to the larger space When the pressure decreases, more air can also enter the flow channel 23 through the air channel 25, thereby increasing the gas content in the water flow.

At the same time, it should be noted that, when the present invention is installed in a situation where the water pressure is sufficient, or an additional power source can be applied to the water source, the setting of the pressure sheet is only required. If the present invention is installed in a general water pressure or a situation where the water pressure is relatively low, the pressure sheet does not need to be provided.

In addition, since the type of the faucet or other water outlet pipes to be installed may be different and have external threads, as shown in FIG. The joint 8 can be used to combine the sleeve 2 with the water outlet pipeline to be installed.

In summary, the micro-bubble generator of the present invention can generate enough bubbles through the water flow through the pressure sheet, the first and second mesh sheets, and the internal structure of the sleeve, and the overall structure Streamlining and saving assembly procedures can indeed achieve the purpose of the present invention.

However, the above are only preferred embodiments of the present invention, and should not limit the scope of the present invention, that is, any simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the contents of the description of the invention, All still fall within the scope of the patent of the present invention.
