In one embodiment, the first wall pipe 100 is longer than the second wall pipe 200, and the portion of the first wall pipe 100 longer than the second wall pipe 200 is used for shielding the air suction opening 203, so that the air suction opening 203 can be shielded by the side water baffle 500, and rainwater suction is reduced.

In one embodiment, the first wall-penetrating pipe 100 is shorter than or equal to the second wall-penetrating pipe 200, and the first wall-penetrating pipe 100 is at least consistent with the wall thickness to satisfy the wall-penetrating effect. The second through-wall pipe 200 shields rainwater by the inner water blocking grille 300 and the side water blocking plate 500, thereby reducing the suction of rainwater.

During installation, the first clamping part 101 at one end of the first through-wall pipe 100 is aligned with the second clamping part 201 at one end of the second through-wall pipe 200, then the first through-wall pipe 100 and the second clamping part 201 are clamped and assembled until one end of the first through-wall pipe 100 is aligned with the other end of the second through-wall pipe 200, then the through-wall pipe is connected with a pipeline of the fresh air conditioner 600 at one end, specifically, the air conditioner drain pipe 800 and the refrigerant pipe 900 penetrate through the first through-wall pipe 100 and are exposed, then the fresh air hose 700 is communicated with the end or the inside of the second through-wall pipe 200, the air tightness of the joint is good, and then the assembled first through-wall pipe 100 and second through-wall pipe 200 penetrate through a wall outlet hole of a wall, so that the assembly of the fresh air conditioner pipeline system is completed.

The air conditioner through-wall pipe disclosed by the invention adopts an independent double-channel mode, an air conditioner refrigerant pipe 900 and an air conditioner drain pipe 800 are integrally formed to pass through a first channel 103 of a first through-wall pipe 100, and a fresh air hose 700 draws air from a second channel 202 of a second through-wall pipe 200. The two channels are connected and fixed through the clamping groove and the clamping buckle. The novel air ventilation device has the advantages that the novel air ventilation area is increased as much as possible while the through-wall size space is met, the novel air quantity is increased, and the installation integrity and convenience are maintained. In order to prevent outdoor rainwater from being sucked through the fresh air channel, the inclined inner water retaining grille 300 with an arc surface is additionally arranged at the inner part of the fresh air channel extending out of the outdoor part, meanwhile, the lower air inlet 400 is arranged at the lower part of the channel, the area of the lower air inlet 400 is smaller than that of the inner water retaining grille 300 with the arc surface, so that the whole air inlet area is increased, the pressure of the air inlet is reduced, and meanwhile, a gap and a drainage wall surface are reserved between the lower air inlet 400 and the inner water retaining grille 300, so that water can flow downwards and drain the wall surface and drop, and the water cannot be directly contacted with the water retaining arc surface to be sucked. A vertical side dam 500 is provided above the side air inlet 301 of the channel to prevent rain water from being directly drawn in from the side. The tail end of the fresh air channel is provided with the embedded inner water retaining grid 300 and the multiple ventilation openings, so that the suction of rainwater can be reduced, and the safety risk of the fresh air module is reduced.

In summary, the wall penetrating pipe with the inner water blocking grating and the fresh air pipeline system of the air conditioner provided by the invention have the following technical effects:

1. the separation of the pipeline and fresh air can be solved by adopting the double independent channels, the whole pipe penetrating area is not increased, and the pipe penetrating hole is beneficial to penetrating through a smaller wall outlet hole;

2. by arranging the concave and inclined arc-shaped inner water blocking grille 300, most of the sucked rainwater can be blocked, and meanwhile, the rainwater can slide along the arc-shaped outer surface, so that the rainwater is prevented from being sucked due to accumulated water;

3. by providing the side water baffle 500 at the suction inlet 203, rainwater is prevented from being directly sucked from the side, and the risk of sucking rainwater from the side is reduced;

4. by arranging the air inlet 203, the lower air inlet 400 and the side air inlet 301, the air inlet area can be increased, and the suction force of a single air inlet can be reduced, so that the probability of sucking rainwater is reduced.

The technical means disclosed by the scheme of the invention is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the invention may occur to one skilled in the art without departing from the principles of the present invention and are intended to be within the scope of the present invention.
