[0006] Further, the gas injection outer pipe comprises a pipe body, an upper sealing plug and a lower sealing plug, the upper sealing plug is provided with a through hole, the upper sealing plug and the lower sealing plug sealingly plug the upper opening and the lower opening of the pipe body respectively, the gas inlet inner pipe extends into the inner cavity of the gas injection outer pipe from the through hole, and the gas inlet inner pipe and the upper plug are sealingly connected.

[0007] A gas pipe joint is used for being mounted into the gas injection hole of the gas injection outer pipe, the outer peripheral end of the gas pipe joint is provided with external threads, the through hole is provided with internal threads, and the gas pipe joint is sealingly screwed into the through hole.

[0008] Furthermore, an adjusting connector is provided between the tracheal connector and the air jet hole. One end of the adjusting connector has an external thread that matches the through hole on its outer peripheral surface, and the other end of the adjusting connector has a threaded hole. The external thread on the outer peripheral surface of the tracheal connector matches the threaded hole.

[0009] Furthermore, the adjusting hole is a screw hole, and the adjusting component is a screw.

[0010] Furthermore, a nut and a washer are provided between the air pipe connector and the air jet pipe.

[0011] Furthermore, a nut and a washer are provided between the adjusting joint and the jet pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model provides a pressurized air pipe, which is constructed by installing an inner air inlet pipe inside the outer air jet pipe. The outlet of the inner air inlet pipe is located at the bottom of the inner cavity of the outer air jet pipe. The inner air inlet pipe extends into the outer air jet pipe, and the gas enters and exits from the bottom of the inner air inlet pipe. The gas moves upward from the bottom of the outer air jet pipe and is then ejected from the outer air jet pipe. Because the inner air inlet pipe is housed within the outer air jet pipe, the volume of the outer air jet pipe is compressed. Compared to existing outer air jet pipes without an inner air inlet pipe, the gas pressure is greater, and the gas volume ejected from each jet hole is more uniform. This solves the problem of inconsistent gas volume at the upper and lower jet holes due to insufficient gas pressure in the prior art. It is also important to note that the diameter of the jet hole is relative to the diameter of the outer air jet pipe. This solution compresses the volume of the outer air jet pipe without changing the diameter of the outer air jet pipe and the jet hole.

[0014] 2. In this design, an air pipe connector is also provided at the air outlet of the air pipe. The air pipe connector is equipped with an adjustment connector. The adjustment connector extends into the inner cavity of the air pipe connector through the adjustment hole, so that when the gas passes through the air pipe connector, it has to pass through a constriction, which can increase the air pressure and enhance the jetting effect.
