[0026] The first nozzle 100 is provided with a first through hole 102, and a third through hole 103 is provided at the end of the first through hole 102, and the diameter of the third through hole 103 is larger than that of the first through hole 102; the second nozzle 200 is inserted into the first through hole 102, and the microbubble hole 202 is provided in the first through hole 102. The third through hole 103 and the first through hole 102 are connected in a stepped manner, and the liquid with bubbles passes through the smaller first through hole 102 and then the larger third through hole 103, and finally is discharged from the gas outlet 101 for use.

[0027] A blocking block 104 is provided at the end of the first nozzle 100, and a blocking hole 1041 is provided on the blocking block 104, and a blocking bolt 1042 is inserted into the blocking hole 1041; a blocking head 203 is provided at the end of the second nozzle 200, and the blocking head 203 abuts against the blocking block 104, and the blocking bolt 1042 is threadedly connected with the blocking head 203; in short, through the provision of the blocking block 104, one end of the first through hole 102 can be blocked, and the connection between the blocking block 104 and the blocking head 203 can be completed through the blocking bolt 1042, and the blocking head 203 can press the blocking hole 1041 to avoid a decrease in air pressure.

[0028] The blocking block 104 is provided with a blocking hole 1043, the blocking head 203 is inserted into the blocking hole 1043, and the side wall of the blocking head 203 fits the side wall of the blocking hole 1043; in short, the side wall of the blocking head 203 fits the side wall of the blocking hole 1043, which can further avoid gas leakage, ensure air pressure, and increase the rate of bubble production.

[0029] The blocking block 104 is provided with an embedded hole 1044, and the head of the blocking bolt 1042 is embedded in the embedded hole 1044; in short, the provision of the embedded hole 1044 can prevent the blocking bolt 1042 from interfering with other components during use.
