In addition, during assembly, only the existing fresh air pipe 20 is required to be inserted into the pipe joint 122, the plurality of tooth-shaped bosses 123 can be in buckle connection with the existing fresh air pipe 20, an assembler is not required to drive the fresh air pipe 20 to rotate relative to the pipe joint 122 so as to realize assembly fixation of the fresh air pipe 20 and the pipe joint 122, and the operation convenience of assembly of the pipe joint 122 and the fresh air pipe 20 is improved.

Specifically, referring to fig. 3 and 4, each of the dental bosses 123 includes a guide surface 1231 inclined from the inner wall of the pipe joint 122 toward the center of the pipe joint 122, a land surface 1232 connected to the guide surface 1231, and an abutment surface 1233 extending from an end of the land surface 1232 facing away from the guide surface 1231 toward the inner wall of the pipe joint 122, wherein an inclination angle β of the abutment surface 1233 is larger than an inclination angle α of the guide surface 1231. For example, the guide surface 1231 has an inclination angle α of 30 ° with respect to the horizontal plane, and the abutment surface 1233 has an inclination angle β of 70 ° with respect to the horizontal plane. During assembly, the fresh air pipe 20 is inserted from one end of the pipe joint 122 far away from the cover plate 121, and when the air outlet end of the fresh air pipe 20 is abutted against the tooth-shaped boss 123, the fresh air pipe 20 slides to the clamping position sequentially through the guide surface 1231, the platform surface 1232 and the abutting surface 1233 of the tooth-shaped boss 123. The clamping position is a position where the tooth-shaped boss 123 is clamped with the external threads 21 of the new air pipe (for example, the tooth-shaped boss 123 is clamped into a clamping groove between two adjacent external threads 21).

Illustratively, the fresh air channel 43 is meniscus-shaped in cross-section. When the fresh air through-wall pipe 40 is installed in the wall body, an installation cavity is formed between the bottom wall 42 and the wall body, and the installation cavity is used for accommodating a pipeline. This embodiment facilitates the stability of the pipeline by isolating the fresh air channel 43 from the pipeline installation cavity.

Further, a drain hole 44 is provided at an end of the fresh air wall pipe 40 near the outside, and the drain hole 44 is provided at the bottom of the fresh air channel 43. In this embodiment, the drain hole 44 is formed in the bottom of the fresh air channel 43, so that water entering the fresh air channel 43 can be timely discharged, and water accumulation in the fresh air through-wall pipe 40 is avoided.

Further, a hood (not shown) is disposed at an end of the fresh air wall pipe 40 facing away from the adapter 30. Specifically, the end of the fresh air through-wall pipe 40 is provided with a mounting plate 45, and the hood is fixed on the mounting plate 45.

Further, referring to fig. 1 and 9, the adapter 30 includes a threaded interface end 31 connected to the fresh air duct 20 and an air duct interface end 32 connected to the fresh air through-wall duct 40. The height of the threaded interface end 31 is greater than the height of the air duct interface end 32. Specifically, the size of the threaded interface end 31 is adapted to the size of the air inlet end of the fresh air pipe 20, a first thread (not labeled in the figure) is provided on the threaded interface end 31, a second thread (which may be the same as or different from the external thread 21) is provided on the fresh air pipe 20, and the threaded interface end 31 and the air inlet end of the fresh air pipe 20 are fixedly connected through the first thread and the second thread. The structure of the air duct interface 32 is the same as or similar to that of the fresh air wall pipe 40, and will not be described again here.

Further, the height of the end of the adaptor 30 connected to the fresh air pipe 20 is greater than the height of the end of the adaptor 30 connected to the fresh air through-wall pipe 40, in other words, there is a height difference between the two connection ends of the adaptor 30. It will be appreciated that since the fresh air wall pipe 40 is in communication with the outside air, for example, the end of the fresh air wall pipe 40 facing away from the adapter 30 extends to the outside, rainwater is likely to enter the fresh air wall pipe 40 when the outside is windy and rainy. In this embodiment, the height of the end, connected to the fresh air pipe 20, of the adapter 30 is greater than the height of the end, connected to the fresh air through-wall pipe 40, of the adapter 30, so that a certain height difference exists between the fresh air through-wall pipe 40 and the fresh air pipe 20 in the gravity direction, and outdoor rainwater is prevented from flowing back into the fresh air pipe 20.
