In the wind swinging device provided by the embodiment, the shaft sleeve 400 is arranged between the driving end 211 of the wind swinging blade assembly and the output shaft 310 of the motor 300, wherein the first shaft sleeve 410 forms protection for the output shaft 310 of the motor 300; the second sleeve 420 sleeved on the driving end 211 of the swing blade assembly is provided with the first edge 423 in a surrounding manner, and the first edge 423 extends to an area outside the through hole 111, so that when the condensed water slides down to the driving end 211 of the swing blade assembly under the action of gravity, the condensed water is accumulated in the second sleeve 420 first, and when the condensed water in the second sleeve 420 overflows, the condensed water overflows to the upper surface of the mounting part 110, so that the wind swinging device provided by the embodiment can effectively prevent the condensed water from falling onto the motor 300 at the bottom of the swing blade assembly by arranging the sleeve 400 and arranging the first edge 423 on the sleeve 400, further reduce the failure rate of the motor 300, prolong the service life of the motor 300, and simultaneously help to eliminate the potential safety hazards such as water short circuit of the motor 300.

Specifically, in this embodiment, the swing blade assembly may include a plurality of swing blades and a connecting rod for connecting all the swing blades, and the plurality of swing blades may include a driving blade 210 and a plurality of driven blades, and the bottom end of the driving blade 210 is the driving end 211 of the whole swing blade assembly. When the air conditioner starts the wind swinging function, the output shaft 310 of the motor 300 drives the driving blade 210 to swing through the shaft sleeve 400, and the driving blade 210 drives the driven blade to swing through the connecting rod.

Specifically, in the present embodiment, the motor 300 is a stepping motor.

Specifically, in the present embodiment, as shown in fig. 1, the bottom end of the first shaft sleeve 410 abuts against the motor 300. The motor 300 supports the first shaft housing 410 and can prevent the entire shaft housing 400 from falling.

Specifically, in the present embodiment, as shown in fig. 2, the first sleeve 410 includes a first bottom wall 411 and a first side wall 412, the second sleeve 420 includes a second bottom wall 421 and a second side wall 422, and the first edge 423 is disposed outside the second side wall 422.

More specifically, in the present embodiment, the first edge 423 is disposed at the top end of the outer side wall of the second sleeve 420, that is, the open end of the second sleeve 420. In this arrangement, when the condensation water in the second sleeve 420 overflows from the opening thereof, the condensation water can directly flow obliquely downward along the upper surface of the first edge 423. In the case where the distance between the first edge 423 and the upper surface of the mounting portion 110 is constant, the height of the second sleeve 420 is relatively low, so that the volume of the accumulated dew is relatively small, and the dew can overflow from the second sleeve 420 relatively timely after flowing into the second sleeve 420, thereby effectively avoiding the phenomenon that a large amount of dew is accumulated in the second sleeve 420.

Of course, in other embodiments of the present application, the location of the first edge 423 on the outer sidewall of the second sleeve 420 is not limited to the top end of the outer sidewall of the second sleeve 420, for example: the first edge 423 may be spaced apart from the top end of the outer sidewall of the second sleeve 420 to ensure a proper distance between the first edge 423 and the upper surface of the mounting portion 110, thereby further inhibiting splashing when the condensation water falls from the first edge 423 to the upper surface of the mounting portion 110.

Specifically, in the present embodiment, as shown in fig. 1 and 2, the upper surface of the first edge 423 extends obliquely downward in a direction away from the outer sidewall of the second sleeve 420. In this arrangement, when the condensation water overflows the opening of the second sleeve 420, the condensation water flows to the upper surface of the mounting portion 110 along the upper surface of the first edge 423, so that the upper surface of the first edge 423 plays a role in guiding the condensation water; in addition, the condensation water flows down along the upper surface of the first edge 423, the first edge 423 also plays a role in buffering the condensation water, and the outer edge of the first edge 423 is nearer to the upper surface of the mounting portion 110, so that the upper surface of the first edge 423 is arranged down in an inclined manner, and can effectively inhibit the condensation water from splashing after falling onto the upper surface of the mounting portion 110, so that the condensation water can be better collected onto the upper surface of the mounting portion 110. In addition, in this arrangement, the lower surface of the first edge 423 may be disposed horizontally, as shown in fig. 2, that is, an included angle α may be formed between the upper surface and the lower surface of the first edge 423, where α is greater than 0 °, so that the position of the first edge 423 near the outer sidewall of the second sleeve 420 is relatively thick, and further, the connection strength between the first edge 423 and the second sleeve 420 is relatively high.

Here, in other embodiments of the present application, the first edge 423 may also extend obliquely downward in a direction away from the outer sidewall of the second sleeve 420. Under this kind of setting form, the thickness of first border 423 is fairly even, can wholly set up fairly thin to can save the material, reduce cost.

Specifically, in this embodiment, as shown in fig. 2, a water blocking edge 112 surrounding the through hole 111 is disposed above the mounting portion 110, and the outer diameter of the first edge 423 is larger than the outer diameter of the water blocking edge 112. In this arrangement, after the condensation water falls from the first edge 423 to the upper surface of the mounting portion 110, the water blocking edge 112 can block the condensation water from flowing down from the through hole 111 to the motor 300, thereby playing a waterproof role.

Specifically, in this embodiment, the edge of the first edge 423 is further provided with a second edge 424, and the minimum inner diameter of the second edge 424 is larger than the outer diameter of the water blocking edge 112. As shown in fig. 2, D2 is the inner diameter of the second rim 424, D1 is the outer diameter of the water deflector rim 112, and D2 and D1 satisfy: d2 > D1. In this arrangement, the second edge 424 can prevent the condensation water (e.g., splashed condensation water) from entering between the water blocking edge 112 and the outer sidewall of the second sleeve 420 from the gap between the water blocking edge 112 and the first edge 423, so as to effectively avoid the condensation water falling to the motor 300 from the path.

More specifically, in the present embodiment, as shown in fig. 1 and 2, the inner diameter of the second rim 424 is substantially uniform along the axial direction thereof, so that the maximum peripheral dimension of the sleeve 400 can be reduced, avoiding interference with other parts. However, in other embodiments of the present application, the inner diameter of the second rim 424 may also be non-uniform, such as: along the direction away from the outer side wall of the second sleeve 420, the second edge 424 extends downward in an overall oblique direction, and the second edge 424 further buffers the condensation water, and at this time, the inner diameter of the second edge 424 is changed from top to bottom to be larger.

Specifically, in this embodiment, the bottom end of the second edge 424 is lower than the top end of the water blocking edge 112. That is, as shown in FIG. 2, H2 < H1, where H2 is the distance between the bottom end of sleeve 400 in assembled relation to the bottom end of second rim 424 and H1 is the distance between the bottom end of sleeve 400 in assembled relation to the top end of water stop rim 112. In this arrangement, the projections of the second edge 424 and the water blocking edge 112 have partial overlapping along the radial direction, so that the second edge 424 can completely block the gap between the top end of the water blocking edge 112 and the lower surface of the first edge 423 along the radial direction, and further, condensation water can be prevented from entering between the water blocking edge 112 and the outer side wall of the second sleeve 420 from between the top end of the water blocking edge 112 and the lower surface of the first edge 423, and the waterproof effect is further improved.

Specifically, in the present embodiment, the bottom wall of the second shaft sleeve 420 (i.e., the second bottom wall 421) is disposed around the outer side wall of the first shaft sleeve 410 and is disposed near the opening of the first shaft sleeve 410. In this arrangement, the axial dimension of the sleeve 400 is smaller, so that the swing blade assembly, the mounting portion 110 and the motor 300 are compact in height direction, thereby contributing to reducing the overall height of the air conditioner, lowering the overall center of gravity of the air conditioner and increasing the stability of the air conditioner.

Specifically, in the present embodiment, the driving end 211 of the swing blade assembly is provided with a jack 212, and the first shaft sleeve 410 is inserted into the jack 212. In this arrangement, the jack 212 reduces the weight of the oscillating vane, which is beneficial to the oscillating vane to oscillate and reduces the power loss for driving the oscillating vane to oscillate; the hole wall of the jack 212 is located between the outer side wall of the first shaft sleeve 410 and the inner side wall of the second shaft sleeve 420, so that the inner side of the hole wall of the jack 212 is limited by the first shaft sleeve 410, the outer side of the hole wall of the jack 212 is limited by the second shaft sleeve 420, and the position stability of the wind swinging blade is better.

The embodiment also provides an air conditioner indoor unit comprising the air swinging device. The indoor unit of the air conditioner has all the advantages of the air swinging device, so that the description is omitted here.
