[0039] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0040] As shown Figure 1 in FIG. 1, the air-sweeping assembly 100 of the embodiment of the present utility model includes a plurality of blades 1 and a connecting rod 3. Each blade 1 can be in the shape of a rectangular plate, and a plurality of through holes can be evenly distributed on each blade 1.

[0041] The plurality of blades 1 are arranged at intervals along a first direction, where the first direction can be the left-right direction. The plurality of blades 1 can be evenly spaced in the left-right direction, and the plurality of blades 1 can be substantially parallel, that is, any one of the plurality of blades 1 can be obtained by translating the other blades 1 in the left-right direction.

[0042] Each blade 1 is provided with a first swing rod 2 for driving the blade 1 to rotate. The connecting rod 3 extends along the first direction, and the connecting rod 3 is rotatably connected to the first swing rods 2 of the plurality of blades 1. For example, the material of each blade 1 can be plastic, and the first swing rod 2 can be provided on each blade 1 by an integral injection molding method, and the extending direction of the first swing rod 2 can form an angle with the plane where the blade 1 is located.

[0043] The material of the connecting rod 3 can also be plastic, etc. The connecting rod 3 can be in the shape of a straight rod and can extend along the left-right direction. The connecting rod 3 can be arranged on the same side of the plurality of blades 1. One end of each first swing rod 2 can be located at the rotation axis of the blade 1 and be fixedly connected to the blade 1, and the other end of each first swing rod 2 can be rotatably connected to the connecting rod 3.

[0044] In some other embodiments, the first swing rod 2 can also be independent of the blade 1. For example, the first swing rod 2 can be assembled on the blade 1 by means of fastening, etc., so as to meet the subsequent use requirements of synchronously driving the first swing rod 2 and the blade 1 to rotate.

[0045] One end of the second swing rod 4 is rotatably connected to the end of the connecting rod 3, and the other end of the second swing rod 4 is connected to the drive shaft of the driver 6. For example, as shown Figure 1 in FIGS. 2 Figure 2 and 3, the second swing rod 4 can be in the shape of a short rod. One end of the second swing rod 4 can be pivotally assembled with the left end of the connecting rod 3, and the other end of the second swing rod 4 can be fixedly connected to the drive shaft of the driver 6, where the driver 6 can be a stepping motor, etc.

[0046] During use, the driver 6 can drive the second swing rod 4 to swing in the left-right direction. For example, when the second swing rod 4 swings to the left, the connecting rod 3 can move leftward. At this time, the plurality of blades 1 can swing to a position perpendicular to the left-right direction. At this time, the plurality of blades 1 switch to the state of blowing air forward, as specifically shown Figure 1 in FIG. 4. When the second swing rod 4 swings to the right, the connecting rod 3 can move rightward. At this time, the plurality of blades 1 can swing to a position of blowing air laterally, as specifically shown Figure 2 in FIG. 5.

[0047] It should be noted that, as Figure 3 and Figure 4 shown, the length dimensions of the first swing rods 2 of each blade 1 can be the same, and multiple first swing rods 2 can be arranged in parallel at intervals in the left - right direction. Thus, any two adjacent first swing rods 2 can form a parallelogram structure. Specifically, reference can be made to Figure 3 and Figure 4 the parallelograms CDEF and EFHG therein, thereby ensuring the synchronization of the swinging of multiple blades 1.

[0048] The length dimension of the second swing rod 4 is greater than that of the first swing rod 2. For example, as Figure 3 shown, the length dimension of the second swing rod 4 can be dimension L1, and the length dimension of the first swing rod 2 can be dimension L2, and dimension L1 is greater than dimension L2. Thus, when the second swing rod 4 swings around point B in Figure 3 , it can play a role in increasing the length of the force arm between point A and point B, thereby increasing the acting force exerted on the connecting rod 3 at point A, and further playing a role in completely flattening and closing multiple blades 1.

[0049] For the sweeping assembly 100 of the embodiment of the present utility model, by increasing the length dimension of the second swing rod 4, the force arm can be increased, and further the acting force exerted on the connecting rod 3 at point A can be increased, so that the connecting rod 3 can be pushed to the right under a larger acting force, avoiding the situation in the prior art where due to the longer connecting rod 3 and smaller acting force, there is a large difference in the rotation angles between some blades 1 on the right side and some blades 1 on the left side, ensuring the consistency of the rotation adjustment amplitude of multiple blades 1, and enabling multiple blades 1 to be completely closed and flattened.

[0050] In some embodiments, the second swing rod 4 and the first swing rod 2 are arranged in parallel at intervals, and the second swing rod 4 is 0.5 mm to 2 mm longer than the first swing rod 2.

[0051] For example, as Figure 3 shown, the length dimension L1 of the second swing rod 4 can be longer than the length dimension L2 of the first swing rod 2, and the difference between the length dimension L1 and the length dimension L2 can be 0.5 mm, 0.8 mm, 1 mm, 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, etc. Within this dimension range, it not only meets the effect of increasing the acting force exerted on the connecting rod 3, but also avoids the situation of the second swing rod 4 being too long, facilitating the installation and arrangement of the second swing rod 4.

[0052] Preferably, the second swing rod 4 is 1 mm longer than the first swing rod 2.

[0053] In some embodiments, a first connection is formed at the connection between the first swing rod 2 and the connecting rod 3, and a second connection is at the connection between the second swing rod 4 and the connecting rod 3. The first connection can be regarded as Figure 3 and Figure 4 at point D in Figure 3 and Figure 4 and the second connection can be regarded as

[0054] at point A in Figure 5 Shown in, at this time, the plane where each blade 1 is located can be parallel to the left - right direction, that is, each blade 1 can be perpendicular to the air - outlet direction, and each blade 1 can be a gentle - wind blade provided with micropores for air to pass through. Due to the action of the through - holes of the blade 1, the air outlet can be gentle wind.

[0055] In the gentle - wind position, the included angle between the line connecting the first connection and the second connection and the first swing rod 2 is angle α, and 8° ≤ α ≤ 90°. For example, as Figure 4 Shown in, the first swing rod 2 and the second swing rod 4 can also generally form a quadrilateral structure. When each blade 1 is switched to the gentle - wind position under the action of the first swing rod 2, at this time, each first swing rod 2 can swing to the right and tilt, and the included angle α formed by the axis of the first swing rod 2 and the line connecting the above - mentioned point A and point B can be 8°, 15°, 20°, 30°, 40°, 50°, 60°, 70°, 80°, 85°, etc.

[0056] Within this angle range, the connecting rod 3 and the first swing rod 2 can always have a certain angle, which can avoid the dead - point situation and ensure the stability and smoothness of the drive.

[0057] In some embodiments, the connecting rod 3 includes a first rod 31 and a second rod 32. Both the first rod 31 and the second rod 32 extend along the first direction. A plurality of first swing rods 2 are all rotationally connected to the first rod 31. One end of the second rod 32 is connected to the first rod 31, and the other end of the second rod 32 is rotationally connected to the second swing rod 4.

[0058] For example, as Figure 6 Shown in, both the first rod 31 and the second rod 32 can extend along the left - right direction. The first rod 31 can be arranged on the right side of the second rod 32. One end of the first swing rod 2 of the above - mentioned plurality of blades 1 can all be rotationally connected to the first rod 31. The left end of the first rod 31 can be fixedly connected to the right end of the second rod 32, and the left end of the second rod 32 can be rotationally connected to one end of the second swing rod 4.

[0059] Since the assembly of the drive part and the multiple blade parts of the air-sweeping assembly 100 can be carried out separately, this split design of the connecting rod 3 meets the usage requirements of such separate installation. After the two parts of the air-guiding assembly are separately installed, the first rod 31 and the second rod 32 can be connected and fixed, thus facilitating the assembly.

[0060] In some embodiments, as Figure 6 shown, the first rod 31 and the second rod 32 are detachably connected by a snap structure 5. This facilitates the connection and disassembly of the first rod 31 and the second rod 32, and improves the convenience of operation.

[0061] In some embodiments, the snap structure 5 includes a snap 51 and a slot 52. One of the snap 51 and the slot 52 is provided on the first rod 31, and the other is provided on the second rod 32. The snap 51 is snap-fitted into the slot 52.

[0062] For example, as Figure 6 shown, the snap 51 can be fixed on the first rod 31, and the slot 52 can be provided on the second rod 32. The slot 52 can be a hole-like structure. During assembly, the snap 51 can be directly inserted into the slot 52. In some other embodiments, the snap 51 can also be provided on the second rod 32, and the slot 52 can also be provided on the first rod 31.

[0063] In some embodiments, the snap 51 is provided with a slotted opening 511. The slotted opening 511 runs through the snap 51 along a second direction, and the second direction is perpendicular to the first direction. For example, the first direction can be the left-right direction, and the second direction can be the front-back direction, the up-down direction, etc. The provision of the slotted opening 511 enables the snap 51 to have elastic deformation performance, that is, the left and right sides of the slotted opening 511 can be squeezed and deformed inward, meeting the usage requirements of snap connection and assembly. Secondly, since the slotted opening 511 extends along the second direction, the extending direction of the slotted opening 511 is substantially perpendicular to the direction of the force applied to the connecting rod 3, thereby ensuring the stability and reliability of the assembly.

[0064] In some embodiments, the snap structure 5 includes a plurality of snaps 51 and a plurality of slots 52. The plurality of snaps 51 and the plurality of slots 52 are both arranged at intervals along the first direction. The plurality of snaps 51 are all provided on the first rod 31, and the plurality of slots 52 are all provided on the second rod 32.

[0065] For example, as Figure 6 shown, two snaps 51 can be provided on the first rod 31, and the two snaps 51 can be arranged at intervals along the left-right direction. Two slots 52 can be provided on the second rod 32, and the two slots 52 can be arranged at intervals along the left-right direction. During assembly, the two snaps 51 are respectively snap-fitted into the two slots 52.

[0066] Thus, the anti-rotation effect can be achieved, that is, the relative rotation between the first rod 31 and the second rod 32 is avoided, ensuring the structural stability of the connection and the force transmission effect.

[0067] In some embodiments, the second rod 32 is provided with a long groove 321, and the long groove 321 extends along the first direction and passes through a plurality of card slots 52. For example, as Figure 6 shown, the long groove 321 can be a rectangular groove, and the long groove 321 can extend along the left-right direction and can pass through the above two card slots 52 at the same time. Thus, the elastic performance of the second rod 32 on both sides of the long groove 321 can be enhanced, facilitating the snap-fit assembly of the snap 51 and the card slot 52.

[0068] In some embodiments, the ratio of the length dimension of the first rod 31 to the length dimension of the second rod 32 is 10 to 15. Specifically, both the length dimension of the first rod 31 and the length dimension of the first rod 31 can be the dimensions in the left-right direction, where the first rod 31 is much longer than the second rod 32, and the length dimension of the first rod 31 can be 10 times, 11 times, 12 times, 13 times, 14 times, 15 times, etc. of the length dimension of the second rod 32.

The air-conditioning equipment can be an indoor unit of an air conditioner, and the wind-sweeping assembly 100 can be installed in the housing of the indoor unit of the air conditioner and can be disposed adjacent to the air outlet of the indoor unit of the air conditioner, thereby meeting the use requirements of wind-sweeping adjustment.

[0071] In some embodiments, as Figure 7 and Figure 8 shown, the indoor unit of the air conditioner includes a wind guide frame 200, the wind-sweeping assembly 100 includes a driver 6, the driver 6 can be a motor, etc., the drive shaft of the driver 6 is connected to the second swing rod 4 and is used to drive the second swing rod 4 to swing, and the wind guide frame 200 is provided with a receiving groove 201. For example, as Figure 8 shown, the receiving groove 201 can be disposed at the end of the wind guide frame 200, and at least part of the driver 6 is assembled in the receiving groove 201, thereby realizing the matching installation of the driver 6 and the wind guide frame 200.
