Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0032] This application provides a sweeping device 100, such as... Figures 1-6 As shown, the air-sweeping device 100 includes a mounting plate 110, air-sweeping blades 120, and a connector 130, with the air-sweeping blades 120 rotatably connected to the connector 130; as Figure 7 As shown, the connector 130 includes a main body 131, a limiting part 132 at one end of the main body 131, and a limiting protrusion 133 on the side wall of the main body 131. The limiting protrusion 133, the side wall of the main body 131, and the limiting part 132 form a mounting groove 134; Figure 5 As shown, the side wall of the mounting hole 111 is provided with a clearance notch 112 for the limiting protrusion 133 to enter and exit. The connector 130 can rotate relative to the mounting plate 110 about the axial direction of the mounting hole 111 so that the edge of the mounting hole 111 enters and exits the mounting groove 134.

[0033] The air-sweeping device 100 provided in this application embodiment, through the cooperation of the connector 130 with the mounting hole 111 and the clearance notch 112, enables the air-sweeping blade 120 to be conveniently and detachably installed on the mounting plate 110. When it is necessary to install the air-sweeping blade 120, such as Figure 8 As shown, simply insert the main body 131 of the connector 130 into the mounting hole 111 of the mounting plate 110, and allow the limiting protrusion 133 to enter the clearance notch 112 of the mounting plate 110, then rotate the connector 130 axially relative to the mounting plate 110 about the mounting hole 111. Figure 8 (rotate clockwise) so that the edge of the mounting hole 111 enters the mounting groove 134 (e.g., rotate clockwise). Figure 9 As shown, the sweeping blade 120 can be installed on the mounting plate 110. When it is necessary to remove the sweeping blade 120, simply rotate the connector 130 relative to the mounting plate 110 around the mounting hole 111 so that the edge of the mounting hole 111 disengages from the mounting groove 134 and the limiting protrusion 133 enters the clearance notch 112 of the mounting plate 110. Then, pull the main body 131 of the connector 130 out of the mounting hole 111 of the mounting plate 110 to remove the sweeping blade 120 from the mounting plate 110. The operation is simple, making the installation and removal of the sweeping blade 120 very convenient and improving the efficiency of the installation and removal of the sweeping blade 120.

[0034] Optionally, the back of the mounting plate 110 is provided with a limiting groove 113. When the edge of the mounting hole 111 enters the mounting groove 134 and the connector 130 rotates relative to the mounting plate 110, the limiting protrusion 133 can be engaged in or disengaged from the limiting groove 113. By setting the limiting groove 113 to cooperate with the limiting protrusion 133, the edge of the mounting hole 111 can be prevented from automatically disengaging from the mounting groove 134, thereby improving the reliability of the connection between the sweeping blade 120 and the mounting plate 110.

[0035] Specifically, when it is necessary to install the sweeping blade 120 onto the mounting plate 110, such as Figure 8 As shown, first insert the main body 131 into the mounting hole 111, and first move the limiting protrusion 133 into the clearance notch 112, then rotate the connector 130 relative to the mounting plate 110 about the axis of the mounting hole 111. Figure 8 Rotate the connector 130 clockwise until the edge of the mounting hole 111 enters the mounting groove 134, and then continue rotating the connector 130 until the limiting protrusion 133 is engaged in the limiting groove 113 (e.g., rotate clockwise). Figure 9As shown, this allows for a reliable connection between the sweeping blade 120 and the mounting plate 110. When the sweeping blade 120 needs to be removed, the connector 130 is rotated axially relative to the mounting plate 110 around the mounting hole 111, causing the limiting protrusion 133 to disengage from the limiting groove 113. Then, the connector 130 is rotated until the edge of the mounting hole 111 disengages from the mounting groove 134, and the limiting protrusion 133 enters the clearance notch 112, allowing the sweeping blade 120 to be removed from the mounting plate 110.

[0036] Optional, such as Figures 3-5 , Figure 8 and Figure 9 As shown, a first guide slope 114 is provided between the clearance notch 112 and the limiting groove 113. The first guide slope 114 is used to guide the limiting protrusion 133 into the limiting groove 113. By setting the first guide slope 114 to guide the limiting protrusion 133 into the limiting groove 113, it is beneficial to improve the assembly efficiency of the connector 130 and the mounting plate 110.

[0037] Optionally, the number of limiting protrusions 133 can be one or more, which can be set according to actual needs. The clearance notch 112, the limiting groove 113, and the first guide slope 114 all correspond one-to-one with the limiting protrusions 133. For example, Figure 5 In the embodiment shown, there are two limiting protrusions 133, which are arranged at intervals along the circumference of the main body 131. There are two clearance notches 112, which correspond one-to-one with the limiting protrusions 133. There are two limiting grooves 113, which correspond one-to-one with the limiting protrusions 133. There are two first guide slopes 114, which correspond one-to-one with the limiting protrusions 133.

[0038] In some embodiments of this application, the sweeping blade 120 includes a connecting shaft 121 and a plurality of blades 122. The connecting shaft 121 is rotatably connected to the connector 130, and the plurality of blades 122 are arranged at intervals along the circumference of the connecting shaft 121. The blades 122 are torsional structures, and the torsional axis of the blades 122 is parallel to the rotation axis of the connecting shaft 121. The air-sweeping device 100 provided in this application embodiment rotatably connects the connecting shaft 121 of the air-sweeping blades 120 to the connector 130. Multiple blades 122 are arranged circumferentially along the connecting shaft 121, and the torsion axis of the blades 122 is parallel to the rotation axis of the connecting shaft 121. Thus, when the air conditioner outlet airflow passes through the blades 122, the rotating blades 122 can disturb the outlet airflow to disperse it. That is, the outlet airflow can be twisted around the torsion axis of the blades 122 and rotated around the rotation axis of the connecting shaft 121 to achieve multi-degree-of-freedom spatial disturbance of the outlet airflow, making the outlet airflow gentler, effectively preventing the air conditioner air from blowing directly on the human body, improving the user's comfort, and reducing health problems caused by the direct blowing of the air conditioner air.

[0039] Optional, such as Figure 6 As shown, the blade 122 has a first end 1221 and a second end 1222. The first end 1221 is twisted relative to the second end 1222 about a torsion axis, and the torsion angle is greater than or equal to 30° and less than or equal to 45°. It should be noted that the torsion angle of the first end 1221 relative to the second end 1222 about the torsion axis refers to the angle swept by the first end 1221 from its initial position to its final position, with the second end 1222 considered fixed, and the first end 1221 twisting clockwise or counterclockwise about the torsion axis. By setting the torsion angle of the first end 1221 relative to the second end 1222 about the torsion axis within the above range, the curvature of the torsional surface of the blade 122 can be made larger, resulting in a significant airflow disturbance, while also reducing the manufacturing difficulty of the blade 122.

[0040] For example, the torsion angle of the first end 1221 of the blade 122 can be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45° or any range between two values. The specific setting can be made according to actual needs, and there is no limitation here.

[0041] In some embodiments of this application, such as Figure 7 As shown, the connector 130 has a locking hole 135, and one end of the connecting shaft 121 has a locking part 123. The locking part 123 is rotatably locked into the locking hole 135, that is, the locking part 123 is locked into the locking hole 135 and can rotate relative to the connector 130 about the axial direction of the locking hole 135. By locking the sweeping blade 120 and the connector 130 through the locking part 123 and the locking hole 135, it is convenient to connect and disassemble the sweeping blade 120 and the connector 130, which helps to improve assembly efficiency. It also facilitates the maintenance and replacement of the sweeping blade 120. That is, it is convenient to disassemble the sweeping blade 120 when it is damaged, repair it, and then reconnect it to the connector 130 or directly replace it with a new sweeping blade 120.

[0042] Optional, such as Figure 6 As shown, one end of the connecting shaft 121 is also provided with a support portion 124, and the support portion 124 and the snap-fit ​​portion 123 form a snap-fit ​​groove 125; as Figure 8 and Figure 9 As shown, the inner wall of the card hole 135 is provided with a limiting flange 136, which is engaged in the card groove 125. By engaging the limiting flange 136 in the card groove 125 formed by the support part 124 and the engaging part 123, this application can prevent the sweeping blade 120 from moving up and down.

[0043] Optional, such as Figure 6As shown, the snap-fit ​​part 123 has a second guide slope 126 on the side opposite to the blade 122. The second guide slope 126 is used to guide the snap-fit ​​part 123 into the snap-fit ​​hole 135. By setting the second guide slope 126 to guide the snap-fit ​​part 123 into the snap-fit ​​hole 135, it is beneficial to improve the assembly efficiency of the sweeping blade 120 and the connector 130.

[0044] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the air-sweeping device includes multiple air-sweeping blades 120, which are spaced apart along the length of the mounting plate 110. Optionally, the air-sweeping blades 120 can be made of a thin material, allowing them to rotate stably and efficiently under the airflow of the air conditioner's fan 210. When the air-sweeping blades 120 rotate, the blades 122 guide the airflow from the air conditioner outlet to expand the air delivery range and disperse the airflow to make the blown air softer, improving user comfort. Alternatively, the air-sweeping blades 120 can be made of other materials, and a drive component (such as a motor) can be used to drive the air-sweeping blades 120 to rotate.

[0045] Optionally, each sweeping blade 120 may contain two or more blades 122, depending on actual requirements. For example, such as... Figure 6 In the embodiment shown, each sweeping blade 120 has six blades 122, and the six blades 122 are arranged circumferentially along the connecting shaft 121.

[0046] This application also provides an air conditioner, such as... Figure 10 and Figure 11 As shown, the air conditioner includes a housing 200 and a sweeping device 100. The specific structure of the sweeping device 100 is as described in the above embodiment. The housing 200 has an air outlet 201, and the sweeping device is disposed at the air outlet 201. The mounting plate 110 of the sweeping device is connected to the housing 200. 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, which will not be described in detail here.

[0047] 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.

[0048] The above provides a detailed description of the air-sweeping device and air conditioner provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
