In this embodiment, The generator body 110 may be, but not limited to, a metal such as stainless steel or brass, or may be a tubular material or plastic having a surface chrome plating or other rust-proof plating layer. In addition, the generator body 110 may be integrally formed. It can also be assembled in segments. The generator body 110 includes a liquid inlet 111 disposed at a leading end of the generator body 110, and a liquid outlet 118 disposed at a tail end of the generator body 110 for facilitating the micro-nano bubble generator 100 and other devices such as a shower device. The first end of the generator body 110 is provided with a first threaded portion 112. Further, in order to facilitate the connection of the micro-nano bubble generator 100 to the pipe for transporting the external liquid, the second threaded portion 119 is disposed on the inner wall of the liquid inlet 111. (Refer to the second figure), connected to the pipe joint of the pipe that transports the external liquid.

After the micro-nano bubble generator 100 is mounted to other devices, in order to prevent the installation of water leakage into the outer wall of the generator body 110, the liquid inlet 111 of the generator body 110 and the outer wall of each end of the liquid outlet 118 are respectively disposed. There are grooves 113, 116, 117 for mounting the seal ring 220 (refer to the fourth figure).

Referring to the second drawing, a gas-liquid mixing portion 120 and a shearing filter portion 140 having at least two layers of screens are sequentially disposed between the liquid inlet 111 and the liquid outlet 118 of the generator body 110. In the present embodiment, the gas-liquid mixed gas refers to air, but is not limited. For example, in other embodiments, it may be ozone or the like, and the liquid refers to tap water, and is not limited as well. In other embodiments, industrial water, aquaculture water, or other liquids that may require gas-liquid mixing may also be used.

The gas-liquid mixing portion 120 includes a liquid processing portion 124, and at least one intake hole 115 that penetrates the liquid processing portion 124 along the outer wall of the generator body 110.

The liquid processing portion 124 includes a constricted section 121 whose cross section is gradually reduced in the direction from the liquid inlet port 111 to the liquid outlet port 118 (i.e., the direction of the arrow 500 shown in the first and second figures), and a mixing section communicating with the suction hole 115. 122. An expanded section 123 having a section that gradually increases in a direction from the inlet port 111 to the outlet port 118 (i.e., in the direction of arrow 500).

In the present embodiment, the air intake hole 115 penetrates into the mixing section 122. Since the mixing section 122 has the smallest cross section in the liquid processing section 124, the air intake hole 115 penetrates into the mixing section 122, which is more advantageous for the gas-liquid to be sufficiently mixed.

In addition, the suction holes 115 may also be disposed along the outer wall to the liquid treatment portion 124, the shape of the section being tapered or the chamfering at the outer wall to ensure that more gas is sucked in.

The number of nanobubbles. In addition, a multi-layer filter can be provided according to actual needs.

In order to reduce the back pressure as much as possible while the shear filter portion 140 generates strong turbulence, the shear filter portion 140 may preferably be provided with a multi-layer screen, and each layer filter uses the above-mentioned separator ring for separating the layers of the screen. The 142 is spaced apart to form the above-mentioned buffer space at 2 to 8.

Further, the mesh of the filter is a hydrophobic metal mesh of 200#~8000#. In an actual combination, if a two-layer filter is used, the mesh number of the first filter 141 may be 200#~800#, and the mesh number of the second filter 143 may be 800#~8000#, to achieve The liquid-liquid mixed liquid is better sheared and filtered out.

Further, in the actual combination, it may be set as the direction of each layer of the filter screen from the liquid inlet port 111 to the liquid outlet port 118 (ie, the direction of the arrow 500), the mesh number is at least the same or layer by layer to achieve the generation. The turbulent flow cuts large bubbles, increases the number of micro-nano bubbles contained in the liquid, and controls the order of the size of the micro-nano bubbles.

Regarding the influence of the number of layers of the buffer space and the combination of different screens on the generated micro-nano bubbles, the inventors conducted a large number of decontamination experiments, and the larger the number of micro-nano bubbles, the smaller the bubbles, the stronger the decontamination ability. Because, by observing the actual decontamination ability of the water filtered by the micro-nano bubble generator 100 with different number of layers of different buffer spaces and different filter screens, the effect of the micro-nano bubbles generated can be directly obtained. . Refer to the table below:

It should be noted that each experiment shown in the above table is only an experimental effect showing a partial combination of various combinations made by the inventors. Referring to the above table, it can be concluded that when the buffer space is the same, when the mesh number of the filter is the same or increases layer by layer, the micro-nano bubble generated is better. In addition, the micro-nano bubbles generated are more effective when the buffer space is more.

In addition, the combination of the shear filter portion 140 may also be a mesh material for other microporous hydrophobic nanomaterials and/or edible water, regardless of whether it is a microporous hydrophobic nano material or a mesh material for edible water, which must be used before use. Rework is achieved to achieve better hydrophobicity.
