For the positions of the two guides 14, the two guides 14 are distributed in the radial direction of the vent pipe 115 at positions near the peripheral edge of the end of the vent pipe 115. When the channel 121 is opposite to the spraying channel 111, the balls 142 of the two guiding elements 14 respectively collide with the inner side walls of the rotating groove 122.

Referring to fig. 9, when the steam delivery amount in the delivery pipe 2 is reduced or withdrawn, the vent pipe 115 and the slide sleeve 113 are retracted into the nozzle 111 by the first elastic member 114. To reset the vent pipe 115, the end of the stopper 112 is also provided in a spiral shape, and the end of the vent pipe 115 is also provided with the guide 14.

The implementation principle of the embodiment is as follows:

when in installation:

the delivery pipes 2 with corresponding specifications and shapes are selected according to the requirements, wherein the more the delivery pipes 2 of bent pipe type are, the higher the rotational freedom degree is, but the more the corresponding bent channels are, and the smoothness of steam delivery is also reduced. After the selection, the part of the conveying pipe 2 with the sliding block 33 is embedded into the fixed unit sleeve 321, the sliding block 33 is embedded into the annular slideway 322, and then the other unit sleeve 321 is mounted on the fixed unit sleeve 321 through the fastening piece 323 to form a complete annular shape and is reinforced through the fastening piece 323. The inlet pipe 4 is then mounted to the gas source via a flange 41.

When in use, the utility model is characterized in that:

the proper spray head 13 is selected, and the rotary table 12 is rotated until the spray head 13 corresponds to the spray seat 11.

The steam generator 5 is filled with medicinal materials and water, and is used for steaming and boiling to generate steam. The exhaust mechanism 63 operates synchronously to draw air into the delivery tube 2 and push the vent tube 115 into the turntable 12 to open the passage of the treatment head 1, exhaust the air originally deposited in the delivery tube 2, and then close the exhaust mechanism 63.

The steam generator 5 generates steam, the steam reaches the treatment head 1 along the steam channel formed by the arm rod 101, after a certain air pressure is accumulated, the ventilation pipe 115 pushes the rotary table 12, and the steam is sprayed out from the hole site of the treatment head 1. At this time, the air supply assistance can be performed by the air exhaust mechanism.

At the same time, the liquefied water in the delivery pipe 2 flows back and is finally stored in the water storage bottle 21. After fumigation is completed, the water storage bottle 21 can be taken out and the water therein can be poured.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
