Such directional nouns do not constitute limitations to the present invention.

[0032] In addition, the terms "first" and "second" mentioned in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0033] Please combine Figure 1 An embodiment of the present invention provides a wind sweeping blade 100 for being pivotally connected to an air guide frame 300 .

[0034] Please combine Figure 2 The wind sweeping blade 100 includes a blade body 110 and a rotating shaft 130 connected to the blade body 110. In a preferred embodiment of the present invention, a notch 120 is provided on the blade body 110, and the rotating shaft 130 is disposed in the notch 120, and both ends of the rotating shaft 130 are connected to the inner side wall of the notch 120. Figure 1 As shown, the wind guide frame 300 is provided with an axis hole 310 , and the rotating shaft 130 is rotatably disposed in the axis hole 310 . The rotating shaft 130 rotates in the axis hole 310 to realize the wind sweeping blade 100 rotating around the central axis of the axis hole 310 .

[0035] In the embodiment of the present invention, the air guide frame 300 is provided with a plurality of shaft holes 310, each shaft hole 310 is cylindrical, any two cross sections of each shaft hole 310 are circles with equal radius, the plurality of shaft holes 310 have the same radius, the central axes of the shaft holes 310 coincide, and each rotating shaft 130 is provided in a shaft hole 310. Figure 3 In the embodiment of the present invention, an axial hole wall 310a is disposed outside the axial hole 310, and the axial hole wall 310a encloses the axial hole 310. Preferably, the axial hole wall 310a is in the shape of two-thirds of a circular ring, and the axial hole wall 310a is provided with a fan-shaped notch 310b in the shape of one-third of a circular ring. It can be understood that the rotating shaft 130 is installed in the axial hole 310 through the fan-shaped notch 310b.

[0036] Please combine Figure 4 The surface of the rotating shaft 130 in contact with the shaft hole 310 is a spherical surface or an ellipsoidal surface protruding toward the inner wall of the shaft hole 310 , and the maximum cross-sectional radius of the rotating shaft 130 is less than or equal to the cross-sectional radius of the shaft hole 310 .

[0037] It can be understood that the surface where the rotating shaft 130 contacts the shaft hole 310 is a spherical surface or an ellipsoidal surface protruding toward the inner side wall of the shaft hole 310, and the maximum cross-sectional radius of the rotating shaft 130 is less than or equal to the cross-sectional radius of the shaft hole 310, which reduces the contact area between the rotating shaft 130 and the shaft hole 310, thereby reducing the friction between the rotating shaft 130 and the shaft hole 310. A gap is left between the rotating shaft 130 and the shaft hole 310, so that even if the rotating shaft 130 is deformed, the wind sweeping blade 100 will not be easily stuck, thereby improving the ability to resist the adverse effects caused by the deformation of the rotating shaft 130.

[0038] It can be understood that when the rotating shaft 130 is set so that the maximum radius of the cross section of the rotating shaft 130 is smaller than the radius of the cross section of the shaft hole 310, the contact between the rotating shaft 130 and the inner wall of the shaft hole 310 is point contact, which further reduces the resistance of the rotating shaft 130 to rotation in the shaft hole 310.

[0039] Please combine Figure 5 In a preferred embodiment of the present invention, the rotating shaft 130 includes a side surface 131 and two end surfaces 133, and the side surface 131 and the two end surfaces 133 form a closed geometric body. Specifically, the side surface 131 is a smooth curved surface, and the radius of the cross section of the rotating shaft 130 decreases from the middle to the two ends. The cross section passing through the midpoint of the central axis of the rotating shaft 130 is the cross section with the largest radius of the rotating shaft 130, and the two end surfaces 133 are the two cross sections with the smallest radius of the rotating shaft 130. Both end surfaces 133 are circular planes, and the radii of the two end surfaces 133 are equal. The rotating shaft 130 is connected to the blade body 110 through the two end surfaces 133.

[0040] It can be understood that the radius of the cross-section of the rotating shaft 130 decreases gradually from the middle to the two ends. The middle part of the rotating shaft 130 is in contact with the shaft hole 310, and a gap is left between the two ends of the rotating shaft 130 and the shaft hole 310. Even if the rotating shaft 130 is deformed, causing the central axis of the rotating shaft 130 to tilt relative to the central axis of the shaft hole 310, the wind sweeping blades will not get stuck easily, thereby improving the ability to resist the impact caused by the deformation of the rotating shaft 130.

[0041] It can be understood that the side surface 131 is a smooth curved surface, and when the shaft 130 is deformed, the contact area between the shaft 130 and the shaft hole 310 is small, and the contact surface is relatively smooth, so the shaft 130 can smoothly rotate relative to the shaft hole 310. This avoids the shaft from getting stuck, and improves the ability to resist the impact caused by the deformation of the shaft 130.

[0042] In a preferred embodiment of the present invention, the side surface of the rotating shaft 130 is a curved surface left by cutting off the two ends of two mutually parallel cross sections of the rugby ball along two sections perpendicular to the long axis of the rugby ball.

[0043] Please combine again Figure 1 and Figure 2In a preferred embodiment of the present invention, the wind sweeping blade 100 includes a mounting post 150, and the mounting post 150 is suitable for being mounted in a mounting hole 350 of the wind guide frame 300. Preferably, the wind sweeping blade 100 includes two mounting posts 150, and the two mounting posts 150 are respectively located at both ends of the wind sweeping blade 100, and the wind guide frame 300 is provided with two mounting holes 350, and the two mounting posts 150 are respectively mounted in the two mounting holes 350.

[0044] Preferably, the mounting column 150 and the mounting hole 350 are both cylindrical, any two cross sections of the mounting column 150 are circles with equal radius, any two cross sections of the mounting hole 350 are circles with equal radius, and the radius of the mounting column 150 is smaller than the radius of the corresponding mounting hole 350. The central axis of the mounting column 150 and the central axis of the mounting hole 350 both coincide with the central axis of the shaft hole 310.

[0045] It can be understood that during the rotation of the wind sweeping blade 100 , the mounting post 150 rotates in the mounting hole 350 , and there is a gap between the mounting post 150 and the mounting hole 350 , thereby reducing the resistance during the rotation.

[0046] like Figure 2 As shown, in a preferred embodiment of the present invention, the sweeping blade 100 further includes a rotating shaft 170, and the rotating shaft 170 and the rotating shaft 130 are arranged on the same side of the sweeping blade 100, and the rotating shaft 170 is farther away from the sweeping blade 100 than the rotating shaft 130. The sweeping blade 100 specifically includes two rotating shafts 170, and the two rotating shafts 170 are respectively arranged at positions of the sweeping blade 100 close to both ends of the sweeping blade 100, and the rotating shaft 130 is arranged between the two rotating shafts 170.

[0047] like Figure 1 As shown, two rotating holes 370 are provided on the air guide frame 300, and the two rotating holes 370 are both cylindrical, and any two cross sections of the rotating holes 370 are circles with equal radius, and the radius of the two rotating holes 370 is equal, and the central axes of the two rotating holes 370 coincide, and the central axes of the two rotating holes 370 are parallel to the central axis of the shaft hole 310. Two rotating shafts 170 are respectively provided in the two rotating holes 370, and the two rotating shafts 170 are suitable for rotating in the rotating holes 370.

[0048] In a preferred embodiment of the present invention, the rotating shaft 170 includes a plurality of circular cross sections with unequal radii, and the radius of the cross sections of the rotating shaft 170 decreases from the middle to both ends.

[0049] It can be understood that when the rotating shaft 170 rotates in the rotating hole 370, the middle part of the rotating shaft 170 is in contact with the rotating hole 370, and a gap is left between the two ends of the rotating shaft 170 and the rotating hole 370. Even if the rotating shaft 170 is deformed, causing the central axis of the rotating shaft 170 to tilt relative to the central axis of the rotating hole 370, the wind sweeping blades will not get stuck easily, thereby improving the ability to resist the impact caused by the deformation of the rotating shaft 170.

[0050] It can be understood that during the rotation of the wind sweeping blade 100, the motor (not shown) of the wind guide frame 300 drives the rotating hole 370 to move, and the rotating hole 370 rotates around the central axis of the shaft hole 310. At the same time, the rotating shaft 130 rotates around the central axis of the shaft hole 310, and the rotating shaft 170 rotates around the central axis of the shaft hole 310 along with the rotating hole 370, thereby realizing the rotation of the wind sweeping blade 100.

[0051] The embodiment of the present invention further provides an air conditioner, comprising the wind sweeping blade 100 provided by the embodiment of the present invention.

[0052] Another embodiment of the present invention provides an air guide frame for pivoting with the wind sweeping blade 700. The air guide frame includes an air guide frame body and a rotating shaft 530 connected to the air guide frame body. In a preferred embodiment of the present invention, a notch is provided on the air guide frame body, and the rotating shaft 530 is provided in the notch, and the two ends of the rotating shaft 530 are connected to the inner side wall of the notch. Figure 6 The wind sweeping blade 700 is provided with an axial hole 730, and the rotating shaft 530 is rotatably provided in the axial hole 730. The axial hole 730 rotates around the rotating shaft 530 with the central axis of the axial hole 730 as the axis to realize the wind sweeping blade 700 rotating with the central axis of the axial hole 730 as the axis.

[0053] In the embodiment of the present invention, a plurality of shaft holes 730 are arranged on the wind sweeping blade 700, and the plurality of shaft holes 730 are arranged on the same side of the wind sweeping blade 700, each shaft hole 730 is cylindrical, and any two cross sections of each shaft hole 730 are circles with equal radius, each shaft hole 730 has the same radius, and the central axis of each shaft hole 730 coincides, and each rotating shaft 530 is arranged in a shaft hole 730. Figure 7 In the embodiment of the present invention, an axial hole wall 730a is provided on the outside of the axial hole 730, and the axial hole wall 730a encloses the axial hole 730. Preferably, the axial hole wall 730a is in the shape of two-thirds of a circular ring, and the axial hole wall 730a is provided with a fan-shaped notch 730b in the shape of one-third of a circular ring. It can be understood that the rotating shaft 530 is installed in the axial hole 730 through the fan-shaped notch 730b.

[0054] Please combine Figure 8The surface where the rotating shaft 530 contacts the shaft hole 730 is a spherical surface or an ellipsoidal surface protruding toward the inner wall of the shaft hole 730 , and the maximum cross-sectional radius of the rotating shaft 530 is less than or equal to the cross-sectional radius of the shaft hole 730 .

[0055] It can be understood that the surface where the rotating shaft 530 contacts the shaft hole 730 is a spherical surface or an ellipsoidal surface protruding toward the inner side wall of the shaft hole 730, and the maximum cross-sectional radius of the rotating shaft 530 is less than or equal to the cross-sectional radius of the shaft hole 730, thereby reducing the contact area between the rotating shaft 530 and the shaft hole 730, thereby reducing the friction between the rotating shaft 530 and the shaft hole 730. A gap is left between the rotating shaft 530 and the shaft hole 730, so that even if the rotating shaft 530 is deformed, the wind sweeping blade 100 will not be easily stuck, thereby improving the ability to resist the adverse effects caused by the deformation of the rotating shaft 530.

[0056] It can be understood that when the rotating shaft 130 is set so that the maximum radius of the cross section of the rotating shaft 130 is smaller than the radius of the cross section of the shaft hole 310, the contact between the rotating shaft 130 and the inner wall of the shaft hole 310 is point contact, which reduces the resistance of the rotating shaft 130 to rotation in the shaft hole 310.

[0057] Please combine Fig. 9 In a preferred embodiment of the present invention, the rotating shaft 530 includes a side surface 531 and two end surfaces 533, and the side surface 531 and the two end surfaces 533 form a closed geometric body. Specifically, the side surface 531 is a smooth curved surface, and the radius of the cross section of the rotating shaft 530 decreases from the middle to the two ends. The cross section passing through the midpoint of the central axis of the rotating shaft 530 is the cross section with the largest radius of the rotating shaft 530, and the two end surfaces 533 are the two cross sections with the smallest radius of the rotating shaft 530. Both end surfaces 533 are circular planes, and the radii of the two end surfaces 533 are equal. The rotating shaft 530 is connected to the air guide frame body through the two end surfaces 533.

[0058] It can be understood that the radius of the cross-section of the rotating shaft 530 decreases gradually from the middle to the two ends. The middle part of the rotating shaft 530 is in contact with the shaft hole 730, and a gap is left between the two ends of the rotating shaft 530 and the shaft hole 730. Even if the rotating shaft 530 is deformed, causing the central axis of the rotating shaft 530 to tilt relative to the central axis of the shaft hole 730, the wind sweeping blades will not get stuck easily, thereby improving the ability to resist the impact caused by the deformation of the rotating shaft 530.

[0059] It can be understood that the side surface 531 is a smooth curved surface. When the rotating shaft 530 is deformed, the contact area between the rotating shaft 530 and the shaft hole 730 is small and the contact surface is relatively smooth, so the rotating shaft 530 can rotate smoothly relative to the shaft hole 730. This avoids the rotating shaft from getting stuck and improves the ability to resist the impact caused by the deformation of the rotating shaft 530.

[0060] In a preferred embodiment of the present invention, the side surface of the rotating shaft 530 is a curved surface left by cutting off the two ends of two mutually parallel cross sections of the rugby ball along two sections perpendicular to the long axis of the rugby ball.

[0061] Please combine again Figure 6 In a preferred embodiment of the present invention, the air guide frame includes a mounting hole, and the wind sweeping blade 700 is correspondingly provided with a mounting post 750, and the mounting post 750 is suitable for being installed in the mounting hole. Preferably, the air guide frame includes two mounting holes, and the wind sweeping blade 700 is correspondingly provided with two mounting posts 750, and the mounting posts 750 are respectively located at both ends of the wind sweeping blade 700, and the two mounting posts 750 are respectively installed in the two mounting holes.

[0062] Preferably, the mounting column 750 and the mounting hole are both cylindrical, any two cross sections of the mounting column 750 are circles with equal radius, any two cross sections of the mounting hole are circles with equal radius, and the radius of the mounting column 750 is smaller than the radius of the corresponding mounting hole. The central axis of the mounting column 750 and the central axis of the mounting hole both coincide with the central axis of the shaft hole 730.

[0063] It can be understood that during the rotation of the wind sweeping blade, the mounting post 750 rotates in the mounting hole, and there is a gap between the mounting post 750 and the mounting hole, which reduces the resistance during the rotation process.

[0064] In a preferred embodiment of the present invention, the air guide frame further includes a rotating shaft, and the air guide frame specifically includes two rotating shafts. Figure 6 As shown, the wind sweeping blade 700 is correspondingly provided with two rotation holes 770, and two rotation shafts are respectively provided in the two rotation holes 770. The rotation hole 770 is suitable for rotating around the rotation shaft with the central axis of the rotation hole 770 as the axis.

[0065] The two rotating holes 770 and the shaft hole 730 are both located on the same side of the wind sweeping blade 700, and the rotating hole 770 is farther away from the wind sweeping blade 700 than the shaft hole 730. The two rotating holes 770 are respectively arranged at positions close to both ends of the wind sweeping blade 700, and the shaft hole 730 is located between the two rotating holes 770. The two rotating holes 770 are both cylindrical, and any two cross sections of the rotating holes 770 are circles with equal radius. The radii of the two rotating holes 770 are equal, and the central axes of the two rotating holes 770 coincide. The central axis of the rotating hole 770 is parallel to the central axis of the shaft hole 730.

[0066] In a preferred embodiment of the present invention, the rotating shaft includes a plurality of circular cross sections with unequal radii, and the radius of the cross sections of the rotating shaft decreases from the middle to both ends.

[0067] It can be understood that when the rotating shaft rotates in the rotating hole 770, the middle part of the rotating shaft is in contact with the rotating hole 770, and a gap is left between the two ends of the rotating shaft and the rotating hole 770. Even if the rotating shaft is deformed, causing the central axis of the rotating shaft to tilt relative to the central axis of the rotating hole 770, the wind sweeping blades will not get stuck easily, thereby improving the ability to resist the impact caused by the deformation of the rotating shaft.

[0068] It can be understood that during the rotation of the wind sweeping blade 700, the motor of the wind guide frame drives the rotating shaft to move, and the rotating hole 770 rotates around the central axis of the shaft hole 730. At the same time, the shaft hole 730 rotates around the rotating shaft 530 with the central axis of the shaft hole 730 as the axis, thereby realizing the rotation of the wind sweeping blade 700.

[0069] Another embodiment of the present invention further provides an air conditioner, comprising the air guide frame provided by another embodiment of the present invention.

[0070] The wind sweeping blades and wind guide frame provided in the embodiments of the present invention reduce the contact area between the rotating shaft and the shaft hole, thereby reducing the friction between the rotating shaft and the shaft hole, and a gap is left between the rotating shaft and the shaft hole. Even if the rotating shaft is deformed, the wind sweeping blades will not get stuck easily, thereby improving the ability to resist the adverse effects caused by the deformation of the rotating shaft.

[0071] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
