the fresh air pipe 100, the fresh air pipe 100 is used for wearing through the through hole 11 on the wall 10. The fresh air duct 100 may be, for example, a corrugated tube, and the fresh air duct 100 itself has certain elasticity, so as to be conveniently stretched according to actual installation requirements.
And the sheath 200 is sleeved on the fresh air pipe 100 and used for being fixed in the through hole 11, and the sheath 200 is positioned on one side of the wall body 11 facing the indoor. The sheath 200 includes a body 210 and a flange 220 disposed at one end of the body 210. The main body 210 is cylindrical, a channel penetrating the main body 210 is formed inside the main body 210, and the main body 210 can be sleeved on the fresh air duct 100. The flange 220 can shield the gap between the body 210 and the through hole 11, thereby preventing insects or impurities in the air from entering the room, and improving the aesthetic property of the indoor side. A plurality of elastic arms 230 are arranged on one side of the body 210, which is far away from the fresh air duct 100, a first end of each elastic arm 230 is fixedly connected with the body 210, and a second end of each elastic arm 230 is a free end; the elastic arm 230 may have a certain elasticity depending on its material, and the elastic arm 230 may be made of, for example, a steel plate, hard plastic, or the like. Alternatively, the entire sheath 200 may be manufactured by integral molding, thereby improving the production efficiency. The surface of the elastic arm 230 on the side away from the body 210 is provided with an anti-falling structure, and the anti-falling structure can increase the friction force between the elastic arm 230 and the inner wall of the through hole 11.

As shown in fig. 6, at this time, the diameter of the through hole 11 is smaller than that of the through hole shown in fig. 5, the elastic arm 230 is further compressed compared to the case shown in fig. 5, the elastic arm 230 still abuts against the inner wall of the through hole 11, and the body 210 can be stably installed in the through hole 11 by the action of the first and second anti-falling off structures 241 and 242 near the body 210.
In a possible implementation, the fresh air duct assembly of the present embodiment further includes:
