Description

Technical Field

[0001] This application relates to the field of air conditioner technology, specifically to a sweeping blade, a sweeping mechanism, and an air conditioner. Background Technology

[0002] In related technologies, some sweeping blades can undergo flexible deformation during the sweeping process to increase the range of motion and sweeping effect. However, the shape of these sweeping blades after flexible deformation is relatively simple, causing the airflow to be blown outward in only one specific direction, resulting in a relatively simple air guiding effect. Utility Model Content

[0003] This application provides a sweeping blade, a sweeping mechanism, and an air conditioner, which can gradually change the airflow direction during the curling and flattening process, so that the airflow can be blown outward in multiple different directions, effectively increasing the richness of the airflow direction.

[0004] In a first aspect, embodiments of this application provide a sweeping blade, comprising a plurality of alternately arranged blade portions and a plurality of rotating connecting portions, wherein any two adjacent blade portions are rotatably connected by a rotating connecting portion, so that the sweeping blade gradually curls or flattens; the sweeping blade has a first vertex, and any two rotating connecting portions share the first vertex as a common endpoint.

[0005] In some embodiments, the rotating connection extends along a curve.

[0006] In some embodiments, the wall thickness of the rotating connection portion is less than the wall thickness of the blade portion connected to the rotating connection portion, or the wall thickness of the rotating connection portion is greater than the wall thickness of the blade portion connected to the rotating connection portion, so as to form a rotation crease between two adjacent blade portions, so that the two adjacent blade portions can be folded or flattened around the rotation crease.

[0007] In some embodiments, the rotating connection is a hinge, so that two adjacent blades can rotate around the rotating connection.

[0008] In some embodiments, when the sweeping blades are unfolded, the sweeping blades are shell-shaped or fan-shaped.

[0009] In some embodiments, the blade portion is formed by two rotating connecting portions and a first curved edge, the two rotating connecting portions having the first vertex as a common endpoint, and the first curved edge connecting the two rotating connecting portions to the end away from the first vertex.

[0010] In some embodiments, when the sweeping blades are flattened, the first curved edges of the plurality of blade portions are sequentially connected to form a smooth curve or a straight line.

[0011] Secondly, embodiments of this application provide a sweeping mechanism, including the sweeping blades provided in any of the above embodiments.

[0012] In some embodiments, the sweeping mechanism includes a plurality of sweeping blades and a connecting rod. The plurality of sweeping blades are arranged sequentially at intervals along the extension direction of the connecting rod, and a blade portion located at one end of the sweeping blade along the curling direction is connected to the connecting rod.

[0013] Thirdly, embodiments of this application provide an air conditioner, including the sweeping blades or the sweeping mechanism provided in any of the above embodiments.

[0014] This embodiment of the application sets up multiple blade sections and multiple rotating connecting sections, with any two rotating connecting sections sharing a first vertex as a common endpoint. Thus, when the sweeping blades oscillate during sweeping, the multiple blade sections can be sequentially folded or flattened around the multiple rotating connecting sections, allowing the sweeping blades to gradually curl or flatten around the first vertex. When curled, they exhibit a curved shape; when flattened, they exhibit a planar shape. This allows the sweeping blades to change between curved and planar shapes during the oscillating sweeping process, thereby causing the airflow at different positions to be blown outwards along the surface of the curved or planar sweeping blades, effectively increasing the richness of the airflow direction and achieving a surround-style airflow effect.

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.

Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0026] like Figures 1 to 3 As shown, in a first aspect, embodiments of this application provide a sweeping blade 1, which includes multiple blade portions 10 and multiple rotating connecting portions 20. It can gradually change the air guiding direction during the curling and flattening process, so that the airflow can be blown outward in multiple different directions, effectively increasing the richness of the airflow direction.

[0027] The aforementioned plurality of blade sections 10 and plurality of rotating connecting sections 20 are alternately arranged, such that a rotating connecting section 20 is provided between any two adjacent blade sections 10; and any two adjacent blade sections 10 are rotatably connected through a rotating connecting section 20, so that the sweeping blade 1 gradually curls or flattens. The sweeping blade 1 has a first vertex 30, and any two rotating connecting sections 20 use the first vertex 30 as a common endpoint, so that the aforementioned plurality of rotating connecting sections 20 form a central radial structure with a common endpoint around the first vertex 30.

[0028] In this way, when the sweeping blade 1 swings and sweeps, the multiple blade sections 10 can be folded or flattened in sequence around the multiple rotating connecting parts 20. Since the multiple rotating connecting parts 20 all take the first vertex 30 as the common endpoint, the sweeping blade 1 can gradually curl or flatten around the first vertex 30. When curled, it presents a curved shape, and when flattened, it presents a planar shape. This allows the sweeping blade 1 to change between a curved shape and a planar shape during the swinging and sweeping process. As a result, the airflow at different positions is blown outward along the surface of the sweeping blade 1, which has a curved shape or a planar shape, effectively increasing the richness of the airflow direction and achieving a surround airflow effect.

[0029] The shape of the rotating connecting portion 20 can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, the rotating connecting portion 20 can be extended along a curve, making the rotating connecting portion 20 a curved connecting portion; furthermore, the bending direction of the curve along which the plurality of rotating connecting portions 20 are located can be set to the same direction, so that the plurality of rotating connecting portions 20 bend towards the same side. Here, the shape of the curve can be determined according to actual needs, and can be a smooth non-linear shape such as an arc, and this application embodiment does not limit it. By setting the rotating connecting portion 20 to a curved shape, the sweeping blade 1 can be better curled to form a smooth curved surface shape, achieving a smoother and more directional air guiding effect.

[0030] In some embodiments, the wall thickness of the rotating connection portion 20 can be less than the wall thickness of the blade portion 10 connected to the rotating connection portion 20, so as to form a rotation crease between two adjacent blade portions 10, allowing the two adjacent blade portions 10 to be folded or flattened around the rotation crease. By setting the wall thickness of the rotating connection portion 20 to be smaller than that of the blade portion 10, the flexibility of the rotating connection portion 20 can be greater than that of the blade portion 10, thereby giving the rotating connection portion 20 the characteristic of being flexibly bent, and serving as a preset rotation crease so that the two adjacent blade portions 10 can be folded or flattened around the rotation crease. Here, the rotating connection portion 20 can be integrally formed with the blade portion 10, but the rotating connection portion 20 is thinned, for example, by filling less material between the two adjacent blade portions 10 during molding to form a thinned portion, or by removing material between the two adjacent blade portions 10 after molding to form a thinned portion.

[0031] In some embodiments, the wall thickness of the rotating connection portion 20 is greater than the wall thickness of the blade portion 10 connected to the rotating connection portion 20, so as to form a rotation crease between two adjacent blade portions 10, allowing the two adjacent blade portions 10 to be folded or flattened around the rotation crease. Here, the rotating connection portion 20 can be integrally formed with the blade portion 10, but the blade portion 10 is thinned, for example, by filling more material between two adjacent blade portions 10 during molding to form a thickened portion, or by removing material from the blade portion 10 after molding to form a thinned portion.

[0032] In other embodiments, the rotating connection portion 20 can be a hinge portion, allowing two adjacent blade portions 10 to rotate around the rotating connection portion 20. Here, each blade portion 10 can be formed separately and then rotatedly connected by the hinge portion.

[0033] The shape of the sweeping blade 1 when flattened can be determined according to actual needs, and this application embodiment does not limit it. In some embodiments, when the sweeping blade 1 is flattened, the sweeping blade 1 can be shell-shaped or fan-shaped. In this way, the sweeping blade 1 can have relatively smooth edges, avoid obstructing airflow, and present a more aesthetically pleasing appearance when flattened.

[0034] In some embodiments, the blade portion 10 may be formed by two rotating connecting portions 20 and a first curved edge 11. The two rotating connecting portions 20 share a common endpoint at a first vertex 30, and the first curved edge 11 connects the ends of the two rotating connecting portions 20 away from the first vertex 30. Furthermore, the first curved edge 11 may be bent toward the side away from the first vertex 30. By setting one side edge of the blade portion 10 as the first curved edge 11, the curved surface air guiding effect can be further increased.

[0035] In some examples, when the sweeping blade 1 is flattened, the first curved edges 11 of multiple blade portions 10 can be connected in sequence to form a smooth curve or straight line, so that the sweeping blade 1 can have a smoother edge, avoid obstructing airflow, and present a more aesthetically pleasing appearance when flattened.

[0036] Secondly, embodiments of this application provide a sweeping mechanism 100, which includes the sweeping blade 1 provided in any of the above embodiments. The sweeping mechanism 100 provided in embodiments of this application has the aforementioned sweeping blade 1, which can gradually change the air guiding direction during the curling and flattening process, so that the airflow can be blown outward in multiple different directions, effectively increasing the richness of the airflow direction.

[0037] In some embodiments, the air-sweeping mechanism 100 may include a plurality of air-sweeping blades 1 and a connecting rod 2. The plurality of air-sweeping blades 1 are arranged sequentially at intervals along the extension direction of the connecting rod 2, and a blade portion 10 located at one end of the air-sweeping blade 1 along the curling direction is connected to the connecting rod 2. In this way, the air-sweeping blade 1 can gradually curl in the direction close to the connecting rod 2, or gradually flatten in the direction away from the connecting rod 2, thereby achieving different air-guiding effects as the connecting rod 2 is driven.

[0038] In some examples, the sweeping mechanism 100 may also include a support plate 3. A plurality of sweeping blades 1 are arranged sequentially at intervals on the support plate 3 along the extension direction of the connecting rod 2, and a blade portion 10 of the sweeping blade 1 away from the connecting rod 2 is fixedly connected to the support plate 3.

[0039] Thirdly, this application provides an air conditioner that includes the sweeping blade 1 or the sweeping mechanism 100 provided in any of the above embodiments. The type of air conditioner can be determined according to actual needs, and can include different types such as wall-mounted air conditioners, cabinet air conditioners, and window air conditioners; this application does not limit this type. The air conditioner provided in this application has the aforementioned sweeping blade 1, which can gradually change the airflow direction during the curling and flattening process, allowing the airflow to be blown outward in multiple different directions, effectively increasing the richness of the airflow direction.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods 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.
