The ultramicro nano bubbles are not influenced by the solubility of air in water, are not limited by external conditions such as temperature, pressure and the like, can stay in water for a long time, and have the obvious effect of improving the dissolved oxygen in water.
The existing nano aeration technology mainly adopts a Roots blower to press air into a gas transmission pipeline and send the air into a microporous pipe, the air is dispersed into water in a micro bubble form, micro bubbles rise from bottom to top to promote oxygen to be fully dissolved into the water, and the rotation and the up-and-down flow of water flow can also be caused, so that the water rich in oxygen on the upper layer of the water surface enters the bottom layer, and the uniform oxygenation of the water body is realized. The method needs special equipment, and has the defects of complex process structure, high cost and easy blockage of micropores.

The inner diameter of the constant diameter part is smaller than that of the connecting part, the inner diameter of the mounting part is larger than that of the constant diameter part, the constant diameter part is communicated with the mounting part through an expanding part with gradually increasing inner diameter, the tail part is communicated with the connecting end after the inner diameter of the tail part is gradually reduced, the inner diameter of the connecting end is constant, and the head part is communicated with the connecting end and then gradually increases.
A gas-liquid mixing cavity is arranged in the mounting part, one side of the gas-liquid mixing cavity is communicated with the expanding part, and the other side of the gas-liquid mixing cavity is communicated with the tail part and the annular groove respectively.
The beneficial effects of the invention are: the ultramicro nano bubble jet aerator adopts a straight-line type ultralow pressure loss structure, and is large in water passing diameter and not easy to block; the direct-discharging type ultra-low pressure loss structure has the advantages that under the condition that the flow is not reduced, the jet flow lift is basically equal to the water pump lift, the direct-discharging type ultra-low pressure loss structure can be used only by being matched with a common water pump (such as a submersible pump and a sewage pump), air is naturally sucked, the matching structure is simple, and the cost is low; the device is suitable for various occasions such as aquaculture, sewage treatment, water purification, water flow generation and the like, and has a wide application range.

fig. 2 is a working principle diagram of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
As shown in fig. 1-2, an ultramicro-nanobubble jet aerator comprises a cylindrical shell 1 and a nozzle tube 2, wherein the cylindrical shell 1 is sequentially provided with a connecting part 3, an equal-diameter part 4 and an installation part 5, the connecting part 3 is used for connecting a high-pressure water tube, the installation part 5 is provided with an air inlet 7, the nozzle tube 2 comprises a connecting end 6 tightly sleeved in the installation part 5, one side of the connecting end 6 extending into the installation part 5 is provided with a tail part 8 in clearance fit with the installation part 5, the other side of the connecting end is provided with a head part 9 exposed out of the installation part 5, and an annular groove 10 communicated with the air inlet 7 is arranged between the tail part 8 and the connecting end 6. Air 14 enters the annular groove 10 through the air inlet 7 and then enters the mounting portion 5 through a gap between the tail portion 8 and the mounting portion 5, ultramicro-nano bubble jet flow 15 is formed between the mounting portion 5 and the high-pressure jet water flow 13, air negative pressure is generated at the mounting portion 5, and the air 14 continuously enters the mounting portion 5 from the air inlet 7.
