The water collecting pipe adopts a split structure composed of straight pipe 1, straight pipe 2 and tee, which is convenient for processing and assembly.

[0014] In the above-mentioned air-conditioning multi-channel duct assembly, the outer side walls of the adjacent ends of straight pipe one and straight pipe two are in close contact with the inner side walls of the two connecting ends to form a seal, that is, straight pipe one and straight pipe two are tightly matched and fixedly connected with the three-way pipe to facilitate assembly of the three.

[0015] In the above-mentioned air-conditioning multi-channel duct assembly, annular steps are provided on the inner walls of the ends away from each other at the two connecting ends, and the rear end face of straight pipe one and the front end face of straight pipe two are respectively pressed tightly against the bottom surfaces of the two annular steps, so that straight pipe one and straight pipe two can be installed in place at one time, further facilitating assembly.

[0016] Compared with the prior art, the air conditioning multi-channel delivery pipe assembly has the following advantages:

[0017] 1. The rubber block is arranged at the rear side of the plugging cover and is inserted into the plugging cover through the positioning block. When in use, the rubber block replaces the plugging cover to contact the fluid. In this way, under the impact of the fluid, not only the rubber block is squeezed into the plugging cover, making the rubber block and the plugging cover pressed tighter and tighter, but also the elasticity of the rubber block can be used to buffer the impact of the fluid, ensuring that the whole formed by the rubber block and the plugging cover is stably positioned in the water collecting pipe, and the structure is relatively stable.

[0018] 2. The rubber block is inserted into the plugging cover through the positioning block, and the front end side wall of the plugging cover is bent inward and contracted to hold the positioning block tightly, so that the rubber block and the plugging cover are stably connected to form a whole, further enhancing the connection strength and stability between the two.

The water collecting pipe 1 adopts a split structure composed of the straight pipe 1b, the straight pipe 2 1c and the tee pipe 1d, which is convenient for processing and assembly.

[0033] Further explanation, the outer side walls of the adjacent ends of the straight pipe 1b and the straight pipe 2 1c are in close contact with the inner side walls of the two connecting ends 1d1 to form a seal, that is, the straight pipe 1b and the straight pipe 2 1c are tightly matched and fixedly connected with the three-way pipe 1d to facilitate the assembly of the three. Furthermore, an annular step 1d2 is provided on the inner wall of the ends away from the two connecting ends 1d1, and the rear end face of the straight pipe 1b and the front end face of the straight pipe 2 1c are respectively pressed tightly against the bottom surfaces of the two annular steps 1d2, so that the straight pipe 1b and the straight pipe 2 1c can be installed in place at one time, further facilitating assembly.

[0034] In actual products, the outer side surface of the rear end of the rubber block 4 is a conical surface 4b, and the diameter of the conical surface 4b gradually decreases from front to back.
