Existing air conditioners or indoor units thereof (hereinafter, simply referred to as "air conditioners") disposed in a conditioned room are generally provided with an air intake opening and an air outlet opening. An air extracting or blowing device (such as a centrifugal fan or an axial flow fan) in the air conditioner sucks air in a conditioned room (which is generally called "return air") or fresh air outside the room into the air conditioner through an air inlet. The air is cooled or heated in the air conditioner by flowing over a heat exchanger arranged in the air conditioner. The cooled or heated air is then delivered into the room through the outlet. Accordingly, the intake vent is generally disposed at the top of the air-conditioning case, and the outtake vent is generally disposed at a lower portion of a front side (which may be referred to as a "front panel") of the air-conditioning case.

The air guide plate and the swing blade mechanism are usually arranged at the air outlet of the air conditioner to adjust the air outlet direction, so that the efficiency of the air conditioner for adjusting the temperature and humidity in a room is improved, and discomfort caused by directly blowing cooled or heated air to a user can be prevented. The air deflector can swing up and down under the driving of the driving mechanism so as to adjust the air outlet of the air outlet in the vertical direction; the swing blade mechanism generally includes a horizontal link and a plurality of swing blades fixed to the link at spaced intervals. The plurality of swing blades can be driven by the connecting rod to rotate left and right simultaneously, so that air outlet channels with different angles are limited, and air outlet in the horizontal direction of the air outlet is adjusted.

Further, the arc-shaped recess may be provided on a left side wall (not shown) of the swing blade main body 411, or the arc-shaped recess may be provided on both the left side wall and the right side wall of the swing blade main body 411.

As shown in fig. 12 to 13, a bracket coupling part 412 is formed at an upper portion of each swing blade main body 411. The bracket connecting portion 412 includes a cylindrical bore 4121 having a generally cylindrical interior cavity. The cylindrical hole 4121 is configured to mate with the corresponding cylinder 4212 of the link groove 421 of the bracket 42 such that each swing leaf 41 is rotatable about the center line C of the bracket link 412. The circular hole 4121 has a hole peripheral wall 4121a extending perpendicularly outward from the swing blade body 411. A radially enlarged portion 4122 extending outward and perpendicular to the hole peripheral wall 4121a is formed at the end of the cylindrical hole 4121, and an annular wall 4123 substantially parallel to the radially enlarged portion 4122 is formed on the hole peripheral wall 4121 a. A predetermined separation distance is formed between radially enlarged portion 4122 and annular wall 4123 along centerline C to form an annular groove between radially enlarged portion 4122 and annular wall 4123. The outer diameter of the annular wall 4123 is greater than the outer diameter of the radially enlarged portion 4122. Based on the orientation shown in FIG. 13, in one or more embodiments, first and second radial notches 4122a, 4122b are provided on the radially enlarged portion 4122 symmetrically in the vertical direction (based on the orientation of FIG. 13). The first and second radial notches 4122a and 4122b are respectively configured to allow a corresponding one of the first and second radial protrusions 4213a and 4213b of the corresponding coupling portion groove 421 of the bracket 42 to pass therethrough. Alternatively, the number of the radial notches may be configured to be other suitable numbers more or less than 2, and the positions of the radial notches may be arranged at other suitable positions of the radially enlarged portion 4122 other than the vertical direction, for example, in the horizontal direction of the radially enlarged portion 4122.

In one or more embodiments, as shown in fig. 14, 4 link grooves 421 having the same structure are provided on each bracket 42. The 4 link grooves 421 are arranged to be evenly spaced apart along the longitudinal direction of the holder 42. Alternatively, the number of the connection portion grooves 421 may be configured to be other suitable number more or less than 4. Each of the link grooves 421 is configured to be inserted into the corresponding first hole portion 3511 or the second bracket mounting hole 352 of the volute tongue 30, and to receive the bracket link 412 of any one of the swing blades 41, so that the swing blade 41 can be detachably and freely rotatably constrained in the link groove 421. As shown in fig. 15 and 17, in one or more embodiments, each link slot 421 has a cylinder 4212 disposed at a bottom 4211. The cylinder 4212 is configured as a generally cylindrical protrusion extending outwardly from the base 4211 in a direction perpendicular to the base 4211. The cylinder 4212 may mate with the cylinder hole 4121 of the bracket connection 412 on the swing leaf 41. In one or more embodiments, a tapered portion 4212a having a predetermined angle is further formed on the end of the cylinder 4212. The diameter of the conical portion 4212a gradually expands along the center line of the cylinder 4212 toward the bottom 4211. The provision of the tapered portion 4212a may allow the cylinder 4212 to fit more easily into the cylinder bore 4121. The predetermined angle may be set to 10 °, or other suitable angle more or less than 10 °. Based on the orientation shown in fig. 15, in one or more embodiments, a first radial projection 4213a and a second radial projection 4213b are formed on the groove peripheral wall 4213 of each connecting portion groove 421 to be opposed to each other in the horizontal direction.

When the swing blade 41 is assembled to the connecting portion groove 421, the cylindrical hole 4121 of the swing blade 41 is firstly opposite to the cylinder 4212 in the connecting portion groove 421, and the cylinder 4212 is inserted into the cylindrical hole 4121; opposing the first radial notch 4122a and the second radial notch 4122b to the first radial projection 4213a and the second radial projection 4213 b; the wobble plate 41 is then rotated about the centerline C of the carrier coupling portion 412 such that the first and second radial protrusions 4213a, 4213b define an annular groove between the radially enlarged portion 4122 and the annular wall 4123 of the carrier coupling portion 412 (at this time, the radially enlarged portion 4122 is defined between the first and second radial protrusions 4213a, 4213b and the bottom portion 4211). Further, the outer diameter of the annular wall 4123 matches the opening diameter of the connecting portion groove 421, so that the annular wall 4123 can enter and completely cover the opening of the connecting portion groove 421, and thus wind does not leak from the connecting portion groove 421. In addition, the outer surface of the annular wall 4123 remains flush with the outer surface of the connecting portion groove 421, which increases the aesthetic appearance of the entire swing blade structure. The radially enlarged portion 4122 is prevented from being removed from the coupling groove 421 by the first and second radial protrusions 4213a and 4213b, thereby restraining the bracket coupling portion 412 of the swing vane 41 in the coupling groove 421. Alternatively, the positions of the first radial protrusion 4213a and the second radial protrusion 4213b may also be provided at other suitable positions of the groove peripheral wall 4213, for example, to be arranged oppositely in the vertical direction. Further, the number of the radial projections may be set to other suitable numbers more or less than 2, as long as it can match with the radial notches so that the radial projections can pass through the radial notches.
