The addition of the transmission gears involved is a conventional technical means for those skilled in the art and will not be described in detail in the present utility model.

[0026] See also Figure 1 to Figure 3 Preferably, a first limit rod passing through a plurality of moving blocks 24 is provided beside the side shaft 23, and both ends of the first limit rod are connected to the support plate 12. A second limit rod passing through the reciprocating seat 27 is provided beside the rotating shaft 26, and both ends of the second limit rod are connected to the frame 1.

[0029] During the implementation of the utility model, the user introduces gas into the vent pipe 11, and the gas enters the aeration head 221 through the connecting pipe 222, and is discharged into the sewage treatment tank at the aeration head 221. Then the user starts the driving member, and the driving member drives the rotating shaft 26 to rotate. Under the cooperation of the reciprocating seat 27 and the third circulation groove, the reciprocating seat 27 drives the rack 271 to reciprocate, so that the central shaft 21 reciprocates. During the rotation of the central shaft 21, under the cooperation of the mounting seat 22 and the first circulation groove, the mounting seat 22 drives the aeration head 221 to reciprocate and lift. During this process, since the driving gear 211 and the driven gear 231 are in meshing state, the side shaft 23 rotates synchronously with the central shaft 21. When the mounting seat 22 moves toward the center direction of the central shaft 21, the moving blocks 24 move away from each other, and the two guide blocks 25 move toward each other; when the mounting seat 22 moves away from the center direction of the central shaft 21, the moving blocks 24 move toward each other, and the two guide blocks 25 move away from each other, which can realize the automatic retraction and release of the connecting pipe 222, avoid the entanglement and knotting of the connecting pipe 222, ensure the smoothness and continuity of the gas transmission process, and thus improve the aeration effect.

[0031] By providing a mounting seat that can be lifted and lowered repeatedly, the aeration head can be driven to perform reciprocating lifting and lowering movements, thereby expanding the movement range of the aeration head and improving the aeration effect;

[0032] By setting structures such as guide blocks and guide plates, the connecting pipe can be automatically retracted and released, reducing the risk of entanglement and knotting of the connecting pipe, thereby ensuring the continuity and smoothness of the gas transmission process.
