[0041] Detailed Implementation

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0043] This application provides a swing assembly, an air conditioner, and an air supply method for the air conditioner. These will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0044] First, this application provides a sweeping blade, such as... Figure 1 As shown, the sweeping blade 122 includes a blade body 1221, which is a non-flat sheet shape, meaning that the blade body 1221 is composed of concave and convex curved surfaces on opposite sides, and the whole is in a twisted state. Since the airflow is blown out along the side of the blade body 1221, the design of the twisted structure of the blade body 1221 can adjust the direction of the airflow.

[0045] Optionally, the blade body 1221 has a first side and a second side facing each other, wherein the first side has a concave surface facing upward along the air outlet direction, and the second side has a concave surface facing downward along the air outlet direction. By designing the orientation of the concave surfaces on the opposite sides of the blade body 1221, the airflow can be directed in different directions when it is blown out along different sides, thereby achieving stratified air outlet.

[0046] It should be noted that in this embodiment, the directions of upward and downward along the air outlet direction are only two relative directions. When the setting position of the sweeping blade 122 relative to the air outlet direction changes, the orientation of the concave surfaces on the first and second sides can change accordingly. It is only necessary to ensure that the first and second sides have concave surfaces with relative orientations to achieve the upper and lower layered air delivery of the sweeping blade 122.

[0047] In this embodiment, the sweeping blade 122 includes a blade body 1221. The blade body 1221 is a non-flat sheet shape, and has a first side and a second side facing each other. The first side has a concave surface facing upward along the air outlet direction, and the second side has a concave surface facing downward along the air outlet direction. By setting the blade body 1221 to a non-flat sheet shape, and having concave surfaces facing upward and downward on opposite sides of the blade body 1221, the blade body 1221 guides the airflow, thereby achieving stratified air outlet.

[0048] Optionally, the blade body 1221 has a first end 1222 and a second end 1223, and the blade body 1221 has a torsion axis extending from the first end 1222 to the second end 1223. That is, the second end 1223 of the blade body 1221 is twisted at an angle relative to the first end 1222 around the torsion axis. Since the blade body 1221 directly guides the airflow, twisting the second end 1223 of the blade body 1221 at an angle relative to the first end 1222 around the torsion axis causes the airflow to be blown out along the torsional surface of the blade body 1221. Through the torsional structure design of the blade body 1221 itself and the coordination of the positions of the blade body 1221, the airflow direction of the blade body 1221 can be optimized, the air supply effect can be improved, and the air supply mode can be more diversified.

[0049] In some embodiments, the torsion axis of the blade body 1221 can be a straight line, that is, extending directly from the first end 1222 of the blade body 1221 to the second end 1223. The entire area of ​​the blade body 1221 is torn around the torsion axis. This structural design is simple and facilitates the control of the air outlet direction by designing the torsion angle of the blade body 1221.

[0050] In other embodiments, the torsion axis of the blade body 1221 includes multiple straight lines, that is, the torsion axis of different regions of the blade body 1221 is different, which makes the torsion mode of the blade body 1221 more diverse, and the control mode of the air outlet direction more diverse.

[0051] In this embodiment, when the torsion axis of the blade body 1221 includes multiple straight lines, these lines can be parallel to each other, meaning that although the torsion axes of different regions of the blade body 1221 are different, their torsion directions are the same; or, the multiple straight lines are arranged at an angle, meaning that the torsion directions of different regions of the blade body 1221 are different, to meet the diverse adjustment of the air outlet direction. In this application embodiment, the torsion axis of the blade body 1221 can be adjusted according to design requirements, meaning that the torsion direction and shape of the blade body 1221 can be adjusted according to design requirements, and no limitations are imposed here.

[0052] Optionally, when the second end 1223 of the blade body 1221 is twisted at an angle relative to the first end 1222 about the torsion axis, the area of ​​the blade body 1221 near the first end 1222 and the second end 1223 can be a flat surface, with the two flat surfaces arranged at an angle and the connecting area of ​​the two flat surfaces transitioned by a curved surface. Although the area of ​​the blade body 1221 near the first end 1222 and the second end 1223 is a flat surface, by arranging the two flat surfaces at an angle, the airflow direction can still be guided, improving the air delivery effect of the blade body 1221 and making the air delivery mode more diversified.

[0053] Optionally, the blade body 1221 is continuously twisted around the torsion axis from the first end 1222 to the second end 1223. That is, the blade body 1221 has two opposing torsional surfaces, and the torsional surfaces are smoothly transitioned by concave and convex arc surfaces, so that the airflow is smoother when it is blown out through the smoothly transitioned torsional surfaces. This can reduce the working noise of the sweeping blade 122 and improve the human sensory comfort.

[0054] It should be noted that the continuous twisting of the blade body 1221 around the twist axis from the first end 1222 to the second end 1223 indicates that the side of the blade body 1221 is a continuous and smooth curved surface. However, the specific shape and twisting method of the blade body 1221 are not limited. That is, the blade body 1221 can adopt various twisting methods such as small-angle twisting, large-angle twisting, symmetrical twisting or asymmetrical twisting. It is only necessary to ensure that the blade body 1221 as a whole has a smooth transition so that the blown airflow is smooth.

[0055] Optionally, the blade body 1221 has equal torsional angles per unit length along the torsion axis, that is, the blade body 1221 is uniformly torsiond from the first end 1222 to the second end 1223. This structural design makes the torsional surface of the blade body 1221 smoother and the airflow blown out through the torsional surface smoother, thereby further reducing the working noise of the sweeping blade 122 and improving human sensory comfort.

[0056] Specifically, when the blade body 1221 is uniformly twisted from the first end 1222 to the second end 1223, if the outline of the blade body 1221 is a regular shape, then the blade body 1221 as a whole is centrally symmetrical with respect to the twist center. If the outline of the blade body 1221 is any other irregular or asymmetrical shape, then the twist center of the blade body 1221 is the geometric center of the outline of the blade body 1221. The uniform twisting design not only improves the smoothness of airflow but also enhances the overall aesthetics of the blade body 1221.

[0057] In some embodiments, the blade body 1221 can be divided into multiple regions from the first end 1222 to the second end 1223 according to design requirements, and each region is uniformly twisted, and the regions are connected by a smooth transition, so as to improve the air outlet method and adjust the air outlet volume.

[0058] The torsion angle of the blade body 1221 from the first end 1222 to the second end 1223 within a unit length can be designed in a stepped manner, such as gradually increasing, gradually decreasing, increasing first and then decreasing, or decreasing first and then increasing. In some embodiments, the torsion angle of the blade body 1221 from the first end 1222 to the second end 1223 within a unit length can also be designed to gradually increase or gradually decrease from both ends to the middle. The specific design method can be adjusted according to actual usage requirements, as long as the air outlet requirements are met.

[0059] Optionally, the second end 1223 of the blade body 1221 is twisted relative to the first end 1222 around the torsion axis at an angle greater than or equal to 5° and less than or equal to 175°. If the torsion angle of the blade body 1221 is too small, the curvature of the torsion surface of the blade body 1221 will be small, and it will not be able to play a significant guiding role; if the torsion angle of the blade body 1221 is too large, the torsion surface of a certain area of ​​the blade body 1221 will be wrapped up, and it will not be able to guide the airflow. At the same time, an excessively large torsion angle will also increase the manufacturing difficulty of the blade body 1221.

[0060] Therefore, in actual production, setting the torsion angle of the blade body 1221 to 5°, 10°, 30°, 60°, 90°, 120°, 150°, or 175° can ensure the guiding effect of the blade body 1221 on the airflow while reducing the manufacturing difficulty and production cost of the blade body 1221. Its specific size can be adjusted according to usage requirements and is not limited here.

[0061] It should be noted that the angle of twist of the second end 1223 of the blade body 1221 relative to the first end 1222 about the torsion axis refers to the angle swept by the second end 1223 from its initial position to its final position, with the first end 1222 considered fixed and the second end 1223 twisted clockwise or counterclockwise about the torsion axis. The design of the torsion angle of the blade body 1221 allows for adjustment of its airflow guidance capability and direction, thereby meeting the needs of different air outlet methods.

[0062] Optionally, in this embodiment, the blade body 1221 is provided with a plurality of soft air holes 1226. The soft air holes 1226 can disperse the airflow passing through the blade body 1221, preventing the airflow from blowing directly onto the human body and improving human sensory comfort. At the same time, by dispersing the airflow, the overall impact force of the airflow on the blade body 1221 can also be avoided, reducing the noise generated during the operation of the sweeping blade 122.

[0063] The axial direction of the soft air hole 1226 is perpendicular to the surface of the blade body 1221, meaning that the soft air hole 1226 passes perpendicularly through the thickness direction of the corresponding position of the blade body 1221. This ensures that the airflow passage through the soft air hole 1226 is aligned with the thickness direction of the blade body 1221, preventing the axial direction of the soft air hole 1226 from tilting relative to the corresponding position of the blade body 1221. This would increase the airflow passage, which would increase the impact time of the airflow on the blade body 1221, causing abnormal noise from the blade body 1221, and would also reduce the actual air volume, affecting the airflow effect.

[0064] In some embodiments, the plurality of soft air holes 1226 are uniformly distributed on the blade body 1221, that is, the spacing between each soft air hole 1226 is equal, and the number of soft air holes 1226 is equal per unit length in the length direction of the blade body 1221, so that the probability of airflow in each region of the blade body 1221 is equal, and the airflow can be evenly dispersed by the blade body 1221 when it flows through the blade body 1221, thereby improving the uniformity of airflow.

[0065] In other embodiments, the multiple soft air holes 1226 are non-uniformly distributed on the blade body 1221. Since the blade body 1221 has a twisted structure, when the blade body 1221 rotates, a part of the blade body 1221 will be blocked by the twisted curved surface, especially the part of the blade body 1221 near the middle area, which makes the actual airflow in this area relatively small.

[0066] When designing the distribution of the soft-wind holes 1226, the distribution density of the soft-wind holes 1226 can be designed to gradually decrease from both ends of the blade body 1221 towards the middle region. This ensures that the blade body 1221 has a wind-softening effect while maximizing the utilization of the soft-wind holes 1226 and reducing production costs. The distribution density of the soft-wind holes 1226 refers to the area occupied by the soft-wind holes 1226 per unit length of the blade body 1221 along its length. The larger the area occupied by the soft-wind holes 1226, the greater the distribution density of the soft-wind holes 1226.

[0067] It should be noted that the area occupied by the soft air holes 1226 is related to both the number and the size of the soft air holes 1226. Therefore, the greater the distribution density of the soft air holes 1226, the more soft air holes there are, or the larger the diameter of the soft air holes 1226, resulting in a larger overall area occupied by the soft air holes 1226.

[0068] In the actual design process, the distribution density of the soft air holes 1226 is changed by altering the number of soft air holes 1226. This is because if the diameter of the soft air holes 1226 is too large, the soft air holes 1226 will not have an obvious effect on dispersing the airflow and will not be able to play the role of soft air; if the diameter of the soft air holes 1226 is too small, the airflow will be too small, affecting the actual air volume and thus affecting the air output effect.

[0069] Secondly, this application provides a sweeping assembly, which includes sweeping blades. The specific structure of the sweeping blades is as described in the above embodiments. Since this sweeping assembly adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments. Further details will not be elaborated here.

[0070] like Figures 1 to 3 As shown, the air-sweeping assembly 120 includes a retaining plate 121, which is used to support other structures in the air-sweeping assembly 120. The air-sweeping assembly 120 is also connected to the external structure through the retaining plate 121 to ensure the stability and normal use of the air-sweeping assembly 120.

[0071] The air-sweeping assembly 120 includes a sweeping blade 122, the blade body 1221 of which is rotatably connected to the clamping plate 121. By rotating the blade body 1221 to the clamping plate 121, the angle of the blade body 1221 relative to the clamping plate 121 can be changed, thereby changing the air outlet direction of the air-sweeping assembly 120 to meet the air outlet requirements at different angles.

[0072] The air-sweeping assembly 120 also includes a drive mechanism 123, which is connected to the blade body 1221 to drive the air-sweeping blade 122 to rotate. The rotation angle of the air-sweeping blade 122 relative to the card plate 121 can be adjusted by controlling the drive mechanism 123, thereby meeting the needs of different air outlet modes of the air-sweeping assembly 120.

[0073] Optionally, the clamping plate 121 has opposing first side surfaces 1211 and second side surfaces 1212. The blade body 1221 is located on the first side surface 1211 of the clamping plate 121, and the blade body 1221 has opposing first ends 1222 and second ends 1223 in a direction away from the first side surface 1211. That is, the first end 1222 is the lower end of the blade body 1221, and the second end 1223 is the upper end of the blade body 1221. The blade body 1221 is twisted in the length direction. At this time, the axis of twist of the blade body 1221 is the length direction of the blade body 1221.

[0074] In some embodiments, the first end 1222 and the second end 1223 are the left and right ends of the blade body 1221, respectively. That is, the blade body 1221 has a third end and a fourth end opposite to each other in the direction away from the first side 1211. The first end 1222 and the second end 1223 are located between the third end and the fourth end. The blade body 1221 is twisted in the width direction. At this time, the twist axis of the blade body 1221 is the width direction of the blade body 1221.

[0075] Optionally, during the use of the air-sweeping assembly 120, the drive mechanism 123 drives the air-sweeping blade 122 to rotate to adjust the air outlet mode of the air-sweeping assembly 120. The air-sweeping blade 122 has a rotation axis relative to the card plate 121, and the torsional axis of the air-sweeping blade 122 extends along the rotation axis, that is, the torsional axis of the air-sweeping blade 122 is consistent with the extension direction of the rotation axis.

[0076] It should be noted that the rotation axis of the sweeping blade 122 is perpendicular to the clamping plate 121. Since the torsion axis of the sweeping blade 122 extends along the length of the blade body 1221, the length of the blade body 1221 is perpendicular to the clamping plate 121. That is, the blade body 1221 is installed perpendicularly to the clamping plate 121. This structure helps to meet the needs of different air outlet modes of the sweeping assembly 120 by adjusting the torsion angle and rotation angle of the blade body 1221 itself.

[0077] In some embodiments, the torsion axis of the sweeping blade 122 extends along the width direction of the blade body 1221, that is, the torsion axis of the sweeping blade 122 is perpendicular to the rotation axis. Similarly, in other embodiments, the torsion axis of the sweeping blade 122 can also extend in other directions and form an angle with the rotation axis, and its specific extension direction can be adjusted according to actual design requirements. During the use of the sweeping assembly 120, different torsion axes correspond to different rotation angle control methods to achieve diversity in the air outlet mode of the sweeping assembly 120.

[0078] Optionally, the angle formed by the extension direction of the edge of the first end 1222 of the sweeping blade 122 and the length direction of the card plate 121 is the first angle, and the angle formed by the extension direction of the edge of the second end 1223 of the sweeping blade 122 and the length direction of the card plate 121 is the second angle.

[0079] When the sweeping blade 122 rotates relative to the clamping plate 121, the angle formed by the extension direction of the two ends of the sweeping blade 122 and the length direction of the clamping plate 121 also changes. By adjusting the first angle and the second angle, it can be determined whether the sweeping blade 122 has rotated to the target air supply position, thereby setting the rotation angle of the blade body 1221 with different torsional structures.

[0080] When in cooling mode, the drive mechanism 123 drives the sweeping blades 122 to rotate to a position where the first included angle is smaller than the second included angle, so that the air volume delivered by the sweeping assembly 120 to the upper region is greater than the air volume delivered to the lower region. Figure 4 As shown, in cooling mode, since cold air gradually moves downwards, the sweeping assembly 120 needs to mainly blow air upwards to achieve a uniform reduction in indoor temperature. When the first included angle is smaller than the second included angle, the degree of obstruction of airflow by the area of ​​the blade body 1221 near the first end 1222 is greater than the degree of obstruction of airflow by the area of ​​the blade body 1221 near the second end 1223. This results in strong winds on the upper side of the blade body 1221 and gentle winds on the lower side. In other words, the air volume delivered by the sweeping assembly 120 to the upper area is greater than the air volume delivered to the lower area, thereby achieving stratified air delivery for cooling.

[0081] It should be noted that, in order to ensure that the difference between the air volume supplied to the upward region and the air volume supplied to the downward region of the sweeping assembly 120 is large enough, that is, to further adjust the air volume supplied to the upward region of the sweeping assembly 120, it is necessary to adjust the difference between the first angle and the second angle so that the difference is greater than or equal to the fifth preset threshold. This ensures that the difference between the first angle and the second angle is large enough, thereby increasing the difference between the degree of obstruction of the airflow by the region of the blade body 1221 near the first end 1222 and the degree of obstruction of the airflow by the region of the blade body 1221 near the second end 1223, so that the air volume supplied to the upward region of the sweeping assembly 120 dominates.

[0082] When in heating mode, the drive mechanism 123 drives the sweeping blades 122 to rotate to a position where the first included angle is greater than the second included angle, so that the air volume delivered by the sweeping assembly 120 to the upper region is less than the air volume delivered to the lower region.

[0083] like Figure 5 As shown, in heating mode, since hot air gradually rises, the sweeping assembly 120 needs to primarily direct airflow downwards to achieve a uniform reduction in indoor temperature. When the first angle is greater than the second angle, the degree of obstruction of airflow by the area near the first end 1222 of the blade body 1221 is less than the degree of obstruction by the area near the second end 1223 of the blade body 1221. This results in a gentle breeze on the upper side of the blade body 1221 and a strong breeze on the lower side. In other words, the airflow delivered by the sweeping assembly 120 to the upper area is less than the airflow delivered to the lower area, thereby achieving stratified airflow for heating.

[0084] It should be noted that, in order to ensure that the difference between the air volume supplied to the upward region and the air volume supplied to the downward region of the sweeping assembly 120 is large enough, that is, to further adjust the air volume supplied to the downward region of the sweeping assembly 120, it is necessary to adjust the difference between the first angle and the second angle so that the difference is greater than or equal to the fifth preset threshold. This ensures that the difference between the first angle and the second angle is large enough, thereby increasing the difference between the degree of obstruction of the airflow by the region of the blade body 1221 near the first end 1222 and the degree of obstruction of the airflow by the region of the blade body 1221 near the second end 1223, so that the air volume supplied to the downward region of the sweeping assembly 120 dominates.

[0085] Optional, such as Figure 6 As shown, when there is a large temperature difference in the indoor area, the air sweeping assembly 120 needs to be adjusted to a wide-area air supply mode, that is, the air sweeping assembly 120 is in the maximum range air supply state. When in the wide-area air supply mode, the drive mechanism 123 drives the air sweeping blades 122 to rotate to a position where the first included angle is greater than or equal to the first preset threshold, and the difference between the first included angle and the second included angle is less than or equal to the second preset threshold, so that the air sweeping assembly 120 performs wide-area air supply, that is, air supply within the maximum range.

[0086] The difference between the first included angle and the second included angle is less than or equal to the second preset threshold, indicating that the angle values ​​of the first included angle and the second included angle are similar. The degree of obstruction of the airflow by the region of the blade body 1221 near the first end 1222 is also similar to the degree of obstruction of the airflow by the region of the blade body 1221 near the second end 1223. The air volume delivered by the sweeping assembly 120 to the upper region is also similar to the air volume delivered to the lower region.

[0087] Furthermore, if the first included angle is greater than or equal to the first preset threshold, it indicates that the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 and the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223 are both small. That is, the overall air volume of the sweeping assembly 120 is large, so as to realize that the sweeping assembly 120 delivers air within the maximum range and reduces the temperature difference between different areas of the room.

[0088] Optional, such as Figure 7 As shown, after the indoor temperature is adjusted to the target temperature, the air sweeping assembly 120 needs to be adjusted to a gentle airflow mode to avoid airflow directly blowing onto the human body and improve human comfort. When in gentle airflow mode, the drive mechanism 123 drives the air sweeping blades 122 to rotate to a position where the first included angle is less than or equal to the third preset threshold, and the difference between the first included angle and the second included angle is less than or equal to the fourth preset threshold, so that the air sweeping assembly 120 can deliver gentle airflow.

[0089] Similarly, if the difference between the first included angle and the second included angle is less than or equal to the fourth preset threshold, it indicates that the angle values ​​of the first included angle and the second included angle are similar. The degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 is also similar to the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223. The air volume delivered by the sweeping assembly 120 to the upper area is also similar to the air volume delivered to the lower area.

[0090] Furthermore, if the first included angle is less than or equal to the third preset threshold, it indicates that the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 and the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223 are both relatively large. That is, the airflow is mainly blown out through the soft air hole 1226 on the blade body 1221 to achieve the soft air delivery of the sweeping assembly 120, avoid the airflow from blowing directly onto the human body, and improve the human comfort.

[0091] Optionally, the card plate 121 of the sweeping assembly 120 has a mounting hole 1213, and the first end 1222 of the blade body 1221 is provided with a mounting part 1224 corresponding to the mounting hole 1213. The mounting part 1224 is rotatably installed in the mounting hole 1213 so that the sweeping blade 122 is rotatably connected to the card plate 121. The mounting hole 1213 facilitates the connection between the sweeping blade 122 and the card plate 121, and also allows for the positioning of the sweeping blade 122, thereby determining the rotation area of ​​the sweeping blade 122 and preventing the sweeping blade 122 from shaking and interfering with each other during rotation.

[0092] Optionally, a first limiting part 1214 protrudes from the inner wall of the mounting hole 1213 on the card plate 121, and a first limiting groove 1225 is formed on the mounting part 1224 corresponding to the position of the first limiting part 1214. The first limiting part 1214 is inserted into the first limiting groove 1225 to realize the connection between the sweeping blade 122 and the card plate 121. At the same time, inserting the first limiting part 1214 into the first limiting groove 1225 can also restrict the axial movement of the sweeping blade 122 in the mounting hole 1213, so that the sweeping blade 122 can only rotate around the rotation axis.

[0093] The first limiting part 1214 extends circumferentially along the inner wall of the mounting hole 1213, and a notch is left on the first limiting part 1214, that is, the first limiting part 1214 is not a complete annular structure. The notch of the first limiting part 1214 facilitates the mounting part 1224 to pass through the first limiting part 1214, thereby inserting the first limiting part 1214 into the first limiting groove 1225 on the mounting part 1224, realizing the connection between the sweeping blade 122 and the card plate 121. The first limiting part 1214 can rotate within the first limiting groove 1225, thereby ensuring that the air outlet mode of the sweeping assembly 120 can be changed by controlling the rotation angle of the sweeping blade 122, thus improving the diversity of the air outlet mode of the sweeping assembly 120.

[0094] It should be noted that the first limiting groove 1225 on the mounting part 1224 can be directly formed on the side wall of the mounting part 1224, or two protrusions can be provided on the mounting part 1224, with the first mounting groove formed between the two protrusions. When the sweeping blade 122 is mounted on the clamping plate 121, the first protrusion located away from the blade body 1221 passes through the notch of the first limiting part 1214. Then, the blade body 1221 is rotated so that the first protrusion is located below the first limiting part 1214, and the second protrusion located near the blade body 1221 is located above the first limiting part 1214, thereby locking the first limiting part 1214 between the two protrusions, realizing the connection between the sweeping blade 122 and the clamping plate 121.

[0095] Optionally, a second limiting groove is provided on the inner wall of the mounting hole 1213 on the card plate 121, and a second limiting part is protruding from the mounting part 1224 corresponding to the position of the second limiting groove. The second limiting part is inserted into the second limiting groove to realize the connection between the sweeping blade 122 and the card plate 121. At the same time, inserting the second limiting part into the second limiting groove can also restrict the axial movement of the sweeping blade 122 in the mounting hole 1213, so that the sweeping blade 122 can only rotate around the rotation axis.

[0096] The second limiting part extends circumferentially along the side wall of the mounting part 1224. When the sweeping blade 122 is connected to the card plate 121, the mounting part 1224 of the sweeping blade 122 is inserted into the mounting hole 1213 at the position corresponding to the second limiting groove. Then, the second limiting part on the mounting part 1224 is inserted into the second limiting groove, and the second limiting part can rotate in the second limiting groove. This ensures that the air outlet mode of the sweeping assembly 120 can be changed by controlling the rotation angle of the sweeping blade 122, thereby improving the diversity of the air outlet mode of the sweeping assembly 120.

[0097] Optionally, in this embodiment of the application, the air-sweeping assembly 120 includes a plurality of air-sweeping blades 122, which are linked together. That is, the rotation of one air-sweeping blade 122 will drive the rotation of the other air-sweeping blades 122. This connection method can simplify the control of the plurality of air-sweeping blades 122, and at the same time, can ensure the consistency of the plurality of air-sweeping blades 122 and improve the air outlet effect of the air-sweeping assembly 120.

[0098] The drive mechanism 123 includes a motor 1231, which has a drive shaft. The drive shaft is connected to one of the sweeping blades 122 to drive the sweeping blade 122 to rotate. The sweeping blade 122 drives the other remaining sweeping blades 122 to rotate synchronously, thereby realizing that one motor 1231 synchronously controls multiple sweeping blades 122 to rotate relative to the plate 121, so as to adjust the air outlet mode of the sweeping assembly 120.

[0099] Optionally, the drive mechanism 123 further includes multiple drive components 1232 and connecting rods 1233. The number of drive components 1232 is equal to the number of sweeping blades 122, and one end of each drive component 1232 is connected to a corresponding sweeping blade 122. The connecting rods 1233 are connected to the other ends of the drive components 1232 to enable the sweeping blades 122 to rotate in a coordinated manner. When the sweeping assembly 120 is working, the motor 1231 drives one of the sweeping blades 122 to rotate. The drive component 1232 on that sweeping blade 122 drives the connecting rod 1233 to rotate, and the connecting rod 1233 drives the drive components 1232 on the other sweeping blades 122 to rotate, thereby causing the other sweeping blades 122 to rotate synchronously.

[0100] The drive component 1232 is connected via connecting rod 1233 to achieve linkage connection of the sweeping blades 122, making the connection between each sweeping blade 122 detachable. When a sweeping blade 122 malfunctions, it can be replaced simply by removing the corresponding drive component 1232 from the connecting rod 1233. Furthermore, by connecting multiple sweeping blades 122 using connecting rod 1233, the specific structure of connecting rod 1233 can be modified, and the distribution and connection method with the clamping plate 121 of the sweeping blades can be adjusted according to actual usage requirements. During the design process, it is only necessary to ensure that connecting rod 1233 can drive the synchronous rotation of multiple sweeping blades 122.

[0101] Finally, this application provides an air conditioner that includes a swing assembly. The specific structure of the swing assembly is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments. Further details will not be elaborated here.

[0102] like Figures 4 to 7 As shown, the air conditioner 10 includes a housing 110, on which an air outlet 111 is provided. A sweeping assembly 120 is installed at the air outlet 111. By designing the structure of the sweeping blades 122 in the sweeping assembly 120 and the rotation angle of the sweeping blades 122, the air outlet mode of the sweeping assembly 120 can be adjusted, thereby achieving different air outlet effects of the air conditioner 10 and meeting different usage needs.

[0103] Optionally, the card plate 121 in the air sweeping assembly 120 has a buckle 1215 protruding on the side opposite to the blade body 1221, and a corresponding slot is provided on the housing 110. By snapping the buckle 1215 into the slot, the card plate 121 and the housing 110 can be connected, thereby connecting the air sweeping assembly 120 and the housing 110.

[0104] During the operation of the air conditioner 10, the rotation angle of the sweeping blades 122 in the sweeping assembly 120 can be adjusted according to different air conditioning operating modes, thereby realizing the control of the air supply mode of the air conditioner 10.

[0105] Specifically, this application describes in detail one embodiment of the air-sweeping blade 122 torsion structure corresponding to the air supply method of the air conditioner 10. Specifically, when viewed from the second end 1223 of the blade body 1221 towards the first end 1222, the blade body 1221 is torsionally counterclockwise relative to the retaining plate 121 at a twist angle of 90°. That is, the first end 1222 of the blade body 1221 remains fixed, while the second end 1223 of the blade body 1221 is torsionally twisted 90° counterclockwise relative to the first end 1222 to form the torsion structure of the blade body 1221.

[0106] When the airflow passes over the blade body 1221, it is guided along the surface of the blade body 1221 and blown out in both vertical and horizontal directions, achieving stratified air delivery. When it is necessary to mainly deliver air upwards or downwards, the air volume in the vertical direction can be controlled simply by changing the rotation angle of the blade body 1221.

[0107] When the blade body 1221 is in the initial state, the blade body 1221 blocks the air outlet 111 to the maximum extent. At this time, the air blown out by the air conditioner 10 is mainly blown out through the soft air hole 1226 on the blade body 1221.

[0108] like Figure 4 As shown, when the air conditioner 10 is adjusted to stratified cooling air supply, the air that needs to be blown out is mainly blown upwards. At this time, the blade body 1221 is controlled to rotate 45° clockwise relative to the initial state. That is, the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 is greater than the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223, so that the upper side is strong wind and the lower side is gentle wind, thereby realizing stratified cooling air supply.

[0109] like Figure 5 As shown, when the air conditioner 10 is adjusted to heating stratified air supply, the air to be blown out is mainly downward. At this time, the blade body 1221 is controlled to rotate counterclockwise by 45° relative to the initial state. That is, the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 is less than the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223, so that the upper side is a gentle breeze and the lower side is a strong breeze, thereby realizing heating stratified air supply.

[0110] like Figure 6 As shown, when there is a large difference in indoor temperature, it is necessary to control the air conditioner 10 to deliver air to multiple areas simultaneously. That is, the air conditioner 10 is adjusted to deliver air to the maximum range of indoor areas. At this time, the blade body 1221 is controlled to rotate 90° clockwise or counterclockwise relative to the initial state. That is, the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the first end 1222 is the same as the degree of obstruction of the airflow by the area of ​​the blade body 1221 near the second end 1223. The upper airflow blows out to the left, and the lower airflow blows out to the right, thereby realizing that the air conditioner 10 delivers air to the maximum range and reduces the temperature difference between indoor areas.

[0111] like Figure 7As shown, after the indoor temperature is adjusted to the target temperature, the air conditioner 10 needs to be switched to the gentle airflow mode. This means the airflow is dispersed by the gentle airflow holes 1226 on the blade body 1221 before being blown out of the air conditioner 10, preventing the airflow from blowing directly onto the human body and improving sensory comfort. Simultaneously, the dispersed airflow reduces the impact on the blade body 1221, thereby reducing the noise generated during the operation of the air sweeping assembly 120. At this time, the blade body 1221 is controlled to rotate to its initial state, where the blade body 1221 blocks the air outlet 111 to its maximum extent, and the air blown out by the air conditioner 10 mainly passes through the gentle airflow holes 1226 on the blade body 1221.

[0112] It should be noted that the rotation angle of the blade body 1221 corresponding to different air supply modes of the air conditioner 10 is related to the torsion angle and torsion method of the blade body 1221. When the torsion angle or torsion method of the blade body 1221 changes, the rotation angle of the blade body 1221 needs to be adjusted accordingly.

[0113] When the blade body 1221 is twisted, the first end 1222 and the second end 1223 of the blade body 1221 can be symmetrically arranged, that is, the twisting center of the blade body 1221 is located at the geometric center of the blade body 1221. This twisting method facilitates the design of the rotation angle corresponding to different air supply modes of the air conditioner 10. In addition, when the twisting direction of the blade body 1221 changes from counterclockwise to clockwise, the rotation angle of the cooling stratified air supply and the heating stratified air supply also needs to be adjusted accordingly to ensure that the blade body 1221 can control the air supply direction.

[0114] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
