A fixture block 131 extends from the end portion of the inner wall of the end cap 13 facing the housing body 12, a first clamping hole 122 is correspondingly formed in the end portion of the housing body 12, and the end cap 13 can be disposed at the end portion of the housing body 12 in a clamping manner by matching and connecting the fixture block 131 with the first clamping hole 122. When the tip of casing body 12 and end cover 13 were assembled, two first muscle positions 121 and end cover 13's inner wall looks butt, just so can enclose by end cover 13, two first muscle positions 121 and the tip of casing body 12 and establish and form above-mentioned new trend passageway, under the negative pressure effect, outdoor new trend can reach air intake 11 via this new trend passageway. Obviously, the first locking hole 122 may be disposed on the end cap 13, and the locking block 131 is disposed on the end of the housing body 12, so that the end cap 13 can be disposed on the end of the housing body 12 by locking. Obviously, the first rib pair may be disposed at the right end of the housing body 12. Of course, the end cap 13 may be disposed at the end of the housing body 12 by screwing, clamping + screwing, bonding, or other methods.

It should be noted that the air inducing component may also be a first rib pair extending from the inner wall of the end cover 13 toward the end of the housing body 12, so that the end cover 13, the two first ribs 121 and the end of the housing body 12 can enclose the fresh air channel when the end of the housing body 12 and the end cover 13 are assembled. Certainly, a third rib position pair may also be extended from the end portion of the housing body 12 toward the end cover 13, and a fourth rib position pair is extended from the inner wall of the end cover 13 toward the end portion of the housing body 12, where the third rib position pair includes two oppositely-arranged third rib positions, and the fourth rib position pair includes two oppositely-arranged fourth rib positions, and when the end portion of the housing body 12 and the end cover 13 are assembled, the third rib position abuts against the fourth rib positions, so that the end cover 13, the two third rib positions, the two fourth rib positions, and the end portion of the housing body 12 can also surround and form the fresh air channel, but this arrangement mode needs to provide a sealing ring or a sealing adhesive or other members capable of ensuring the sealing performance of the fresh air channel between the third rib position and the fourth rib position. On the premise of not deviating from the principle of the present application, a person skilled in the art can flexibly select a specific manner of forming the fresh air channel between the end cover 13 and the end portion of the housing 1 according to a specific application scenario, as long as the fresh air channel capable of allowing fresh air to pass through can be formed between the end cover 13 and the end portion of the housing 1.

As shown in fig. 1 to 4, 6 and 7, the induced draft assembly further includes a pair of sealing ribs disposed on the inner wall of the end cover 13, the pair of sealing ribs includes two sealing ribs 132 disposed oppositely, and the sealing ribs 132 are substantially in a long strip shape and disposed along the length direction of the first rib position 121. When the tip of casing body 12 and end cover 13 were assembled, two sealed muscle 132 were located the outside of two first muscle positions 121 respectively, cooperated respectively with two first muscle positions 121, just so can ensure the leakproofness of new trend passageway through the cooperation of sealed muscle 132 with first muscle position 121, just so can introduce outdoor new trend to the indoor space through new trend passageway better.

It should be noted that the two sealing ribs 132 may be located inside the two first rib positions 121, or one sealing rib 132 may be located inside the first rib position 121 and the other sealing rib 132 may be located outside the first rib position 121. Obviously, the induced air subassembly also can not include sealed muscle pair, nevertheless probably has the poor problem of fresh air channel leakproofness. On the premise of not deviating from the principle of the present application, a person skilled in the art can flexibly select a specific setting mode of the sealing rib pair according to a specific application scenario, as long as the sealing performance of the fresh air channel can be ensured by the cooperation of the sealing rib 132 and the first rib position 121.

As shown in fig. 1 to 4, 6 and 7, the air inducing assembly further includes a second rib position pair extending from the end (i.e., the left end shown in fig. 1) of the housing body 12 toward the end cap 13, the second rib position pair includes two second rib positions 123 disposed oppositely, the second rib positions 123 are substantially in a long strip shape and are disposed along the flow direction of the fresh air (substantially from the lower rear to the upper front shown in fig. 1), the second rib positions 123 are located inside the first rib positions 121, and when the end of the housing body 12 and the end cap 13 are assembled, the second rib positions 123 abut against the inner wall of the end cap 13. Therefore, the end cover 13, the two second rib positions 123 and the end of the housing body 12 enclose the fresh air channel. Under the negative pressure, when the new trend enters into the interior space via the new trend passageway, even if some new trend leaks via the gap between the inner wall of second muscle position 123 and end cover 13, also can be blockked by first muscle position 121, sealed muscle 132. Through the setting of this two-layer muscle position of inside and outside of first muscle position 121 and second muscle position 123 like this to can be better with new trend passageway with outside isolated, together with sealed muscle 132, ensure new trend passageway's leakproofness better. Moreover, the strength of the end of the housing body 12 can be enhanced by the second rib 123. Obviously, the induced draft assembly may not include the second rib position pair.

As shown in fig. 6 and 7, the second rib position 123 is substantially parallel to the first rib position 121, so that even if the second rib position 123 is disposed inside the first rib position 121, the flow area of the fresh air channel is not affected, the flow space of the fresh air channel is ensured to be as large as possible, and as much fresh air as possible can be allowed to pass through, thereby better improving the air quality of the indoor space. Obviously, the second rib bit 123 may be only partially parallel to the first rib bit 121 and partially not parallel to the first rib bit 121. Of course, the second rib 123 may not be parallel to the first rib 121, but this arrangement may affect the flow area of the fresh air channel.

As shown in fig. 1 to 4, 6 and 7, the housing 1 further includes a front panel 14 provided on the front side of the housing body 12, the front panel 14 being provided on the outer side of the filter member 3. The end of the housing body 12 near the air inlet 11 is formed with a fresh air outlet 124, and the fresh air outlet 124 is substantially triangular. The fresh air outlet 124 is provided with a rib 125, the rib 125 divides the fresh air outlet 124 into a first part 1241 and a second part 1242, the first part 1241 is located between the evaporator 2 and the filter member 3, and the second part 1242 is located between the filter member 3 and the front panel 14. Thus, part of the fresh air coming out from the fresh air outlet 124 enters the area between the evaporator 2 and the filter component 3 through the first part 1241, and enters the indoor space through the air outlet after exchanging heat with the evaporator 2, the part of the fresh air does not flow through the filter component 3, the resistance is small, the fresh air possibly contains impurities but has large suction force, and the fresh air volume can be ensured; the other part enters the area between the filter element 3 and the front panel 14 through the second part 1242, the part of air passes through the filter element 3 to filter impurities in the air and then exchanges heat with the evaporator 2, and the part of fresh air passes through the filter element 3 to be filtered, so that the resistance is high, but the air introduced into the indoor space can be ensured. Therefore, enough fresh air volume can be ensured to be introduced, fresh air can be properly filtered, and secondary pollution to indoor space is avoided. Moreover, all the fresh air enters the indoor space after exchanging heat with the evaporator 2, so that the temperature range fluctuation of the indoor space caused by overhigh or overlow temperature of the fresh air entering the indoor space can be avoided, and the air quality of the indoor space can be better improved. Obviously, it is also possible to have the fresh air outlet 124 entirely between the evaporator 2 and the filter member 3, but this arrangement may cause secondary pollution to the indoor space by fresh air introduced when the outdoor air quality is poor, or to have the fresh air outlet 124 entirely between the filter member 3 and the front panel 14, but this arrangement may have a possibility of insufficient fresh air volume.

As shown in fig. 1, 6 to 8, the wall-mounted fresh air conditioner further includes an air guide portion 4, the air guide portion 4 includes a first mounting plate 41 and a second mounting plate 42, the first mounting plate 41 and the second mounting plate 42 extend substantially in directions perpendicular to each other, and a fresh air inlet 411 is provided on the first mounting plate 41. The end of the first side of the second mounting plate 42 facing the housing body 12 is provided with a first buckle 421, the housing body 12 is provided with a first mounting hole 15 at a corresponding position, and the first buckle 421 can be connected with the first mounting hole 15 in a matching manner. The second side of the second mounting plate 42 is provided with a second mounting hole 422, the end of the housing body 12 is provided with a mounting post 126 at a corresponding position, the mounting post 126 is arranged between the first rib position 121 and the second rib position 123, and the mounting post 126 is provided with a third mounting hole 1261. During installation, the first buckle 421 is first matched with the first installation hole 15, and then a fastener (such as a screw, a bolt, etc.) is connected with the third installation hole 1261 after passing through the second installation hole 422, so that the induced draft part 4 is disposed at the end of the housing body 12.
