[0027] The pipeline structure 1 is connected to the docking structure 3 and the adjustment structure 4 through the threaded docking end 102 of the connecting pipe 101 and the fitting ring 103, and is connected to other interfaces of the air-conditioning pipeline through the docking structure 3 and the adjustment structure 4. The temperature variable structure 2 can regulate the temperature of the pipe body according to needs to improve the efficiency of cooling and heating.

[0028] The temperature-changing structure 2 includes a cooling sleeve 201 , a heating sleeve 202 , and a connecting line 203 . The cooling sleeve 201 is sleeved on the connecting pipe 101 .

The heating sleeve 202 is installed on the connecting pipe 101 .

[0029] The cooling sleeve 201 and the heating sleeve 202 of the temperature variable structure 2 are connected to the control device through the connecting line 203. During the cooling process of the air conditioner, the power on and off of the cooling sleeve 201 can be controlled to cool down the semiconductor cooling end of the cooling sleeve 201, so that the tube body of the connecting pipe 101 can be quickly cooled down to improve the cooling effect. When heating is needed, the power on and off of the heating sleeve 202 is controlled to preheat the connecting pipe 101 with the resistance heater to improve the heating effect.

[0030] The docking structure 3 includes a docking tube 301, a first through hole 302, a second through hole 303, an engaging groove 304, a docking thread 305, and a pipeline channel 306.

During the cooling process of the air conditioner, the semiconductor cooling end of the cooling sleeve 201 can be cooled by controlling the power on and off of the cooling sleeve 201. The tube body of the connecting tube 101 can cool down quickly to improve the cooling effect. When heating is needed, the power of the heating sleeve 202 is controlled to be on and off, so that the resistance heater preheats the connecting tube 101 to improve the heating effect. After the docking tube 301 of the docking structure 3 is connected to the connecting tube 101, the internal air pressure of the first airbag ring 401 and the second airbag ring 402 is controlled through the internal adjustment structure 4 to expand the airbag.
