[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] like Figure 1 , 2 As shown, an air conditioner outer cover includes a cylindrical frame 1, both ends of the frame 1 are penetrated, the frame 1 is provided with an air inlet end 2, an exhaust frame 3 is detachably connected to the air inlet end 2, exhaust blades 4 are coaxially rotatably connected to the exhaust frame 3, an air guide portion 5 is provided at one end of the inner side of the exhaust frame 3 away from the air inlet end 2, and the side of the air guide portion 5 close to the air inlet end 2 extends into the air inlet side edge of the exhaust blade 4.

[0021] In this embodiment, a filter screen 6 is provided at an opening on one side of the exhaust frame 3 away from the air inlet end 2 , and a rotation center of the exhaust blade 4 is located in the middle of the filter screen 6 .

[0022] In this embodiment, the air guide portion 5 includes an air inlet section 51, an air induced section 52 and an air guide section 53. The air inlet section 51 is arc-shaped, and the front end of the air inlet section 51 extends into the air inlet side edge of the exhaust blade 4. The air inlet end 2 of the air induced section 52 is connected to the air inlet section 51, and the air induced section 52 is connected to the air guide section 53. The air guide section 53 extends radially outward from the air inlet end 2 to the air outlet end along the frame 1.

[0023] In this embodiment, the distance between the air inlet section 51 and the air inlet side of the exhaust blade 4 is shortened radially outward.

[0024] In this embodiment, the air induction section 52 extends along the axial direction of the frame 1 .

[0025] In this embodiment, a reinforcing rib 7 is provided on the inner side of the exhaust frame 3 . The reinforcing rib 7 extends along the radial direction of the frame body 1 . One end of the reinforcing rib 7 is connected to the inner side of the air induction section 52 .

[0026] like Figure 2 As shown, by setting the reinforcing rib 7, the use strength of the air induction section 52 is improved, and the structural strength is improved; and because one end of the reinforcing rib 7 is connected to the inner side of the air induction section 52, the reinforcing rib 7 does not affect the guiding effect of the air guide part 5 on the wind force, and the structure is ingenious.

[0027] In this embodiment, a disassembly groove 8 is opened in the frame body 1, and an elastomer 9 is provided on the exhaust frame 3. The elastomer 9 is arranged in the disassembly groove 8, and the exhaust frame 3 is coaxially inserted into the frame body 1. The radial deformation of the elastomer 9 is greater than the distance of the part of the elastomer 9 extending into the disassembly groove 8.

[0028] like Figure 2 As shown, the installation and removal of the exhaust frame 3 are achieved by taking out or installing the elastomer 9. Since the radial deformation of the elastomer 9 is greater than the distance of the elastomer 9 extending into the disassembly groove 8, when the exhaust frame 3 is coaxially inserted into the frame body 1, the elastomer 9 is effectively stabilized. After the elastomer 9 is retracted into the disassembly groove 8, it also cooperates to fill the disassembly groove 8. The elastomer 9 ensures a stable connection between the frame body 1 and the exhaust frame 3, thereby improving the structural stability.

[0029] Working principle: Figure 1 , 2 As shown, when air is introduced along the air inlet section 51 of the frame 1, the exhaust blade 4 is driven to rotate, and the exhaust blade 4 effectively reduces the exhaust impact of the wind, reduces the impact of the wind on the air outlet end of the frame 1, and ensures safety in use; because the air inlet end 2 of the air guide portion 5 extends into the air inlet side edge of the exhaust blade 4, specifically, the front end of the air inlet section 51 extends into the air inlet side edge of the exhaust blade 4, when the wind diffuses outward along the exhaust blade 4, it is discharged outward along the air inlet section 51, the air induction section 52 and the air guide section 53 in sequence; as shown in FIG. Figure 1 , 2As shown, since the air inlet section 51, the air induced section 52 and the air guide section 53 all extend radially along the frame 1, eddy currents are effectively prevented from being generated in the exhaust frame 3, noise is reduced, and the quality of use is improved. It is more in line with the use requirements of the sleep mode and is convenient for providing sleeping conditions. Since the distance between the air inlet section 51 and the air inlet side of the exhaust blade 4 is shortened radially outward, when the wind is driven by the exhaust blade 4 and diffuses toward the periphery, it can smoothly flow into the air inlet section 51 along the outer end of the exhaust blade 4, effectively reducing wind loss and improving wind utilization. After passing through the air guide section 53, the wind is filtered by the filter 6 and then discharged. The discharged air is clean and hygienic, and can effectively reduce noise, prevent the formation of a strong turbulent area at the outlet end of the exhaust frame 3, avoid the formation of backflow, and improve the quality of use.
