In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0040] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can, for example, be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0041] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0042] Combine Figures 1 to 4 As shown, according to a specific embodiment of the present application, a fan blade assembly is provided.

[0043] Specifically, the fan blade assembly includes a first support member 1, a second support member 2, and a fan blade portion 3. The second support member 2 is disposed on the inner ring of the first support member 1, and the fan blade portion 3 is movably connected to the first support member 1 and the second support member 2, respectively. The fan blade portion 3 has a storage position in which it is contracted along the radial direction of the fan blade portion 3, and an operating position in which the fan blade portion 3 extends along the radial direction of the fan blade portion 3. The fan blade portion 3 is switched between the storage position and the operating position by rotating one of the first support member 1 and the second support member 2 relative to the other in a predetermined direction.

[0044] In an embodiment of the present application, the fan blade portion 3 is rotated by operating one of the first support member 1 and the second support member 2, thereby realizing a change in the diameter size of the fan blade assembly, so that the fan blade portion can shrink or stretch in the radial direction. When the fan blade assembly is in a non-working state, the fan blade portion shrinks in the radial direction to a storage position to reduce the space occupied by the fan blade assembly. The fan blade portion stretches radially until the fan blade assembly is in a working position, which can increase the size of the fan blade assembly, so that when the fan blade assembly is in a working state, it can improve the air outlet efficiency and air outlet volume, and reduce noise. The fan blade assembly can achieve diameter change, so that the applicability of the fan blade assembly is improved.

[0045] Furthermore, the fan blade portion 3 includes a plurality of fan blades 31 , which are arranged circumferentially around the first support member 1 and the second support member 2 , and each fan blade 31 is movably connected to the first support member 1 and the second support member 2 via a connecting member 32 .

[0046] It should be noted that the fan blade 31 is arranged to be relatively rotatable relative to the first support member 1 and the second support member 2, so that the fan blade 31 can be offset along the radial direction of the first support member 1 and the second support member 2, thereby adjusting the distance between the fan blade 31 and the center of the first support member 1 and the second support member 2, thereby realizing the contraction and extension of the fan blade part 3 along its radial direction.

[0047] Furthermore, a plurality of first connecting shafts 11 are evenly distributed around the circumference of the first support member 1, and a plurality of second connecting shafts 21 are evenly distributed around the circumference of the second support member 2. Each connecting member 32 is rotatably connected to one of the first connecting shaft 11 and the second connecting shaft 21, and is slidably connected to the first connecting shaft 11 and the second connecting shaft 21. In this embodiment, the direction of the sliding connection is along the length direction of the connecting member 32. The first connecting shaft 11 or the second connecting shaft 21 is slidably connected to the connecting member 32 to change the distance between the first connecting shaft 11 and the second connecting shaft 21, thereby allowing the first support member 1 to rotate relative to the second support member 2, thereby achieving the storage and extension of the fan blade portion. Specifically, when the fan blade 31 is in the storage position, the first connecting shaft 11 and the second connecting shaft 21 are relatively far apart, and when the fan blade 31 is in the working position, the first connecting shaft 11 and the second connecting shaft 21 are relatively close.

[0048] It should be noted that the first connecting axis and the second connecting axis connected by each connecting member 32 are arranged in a one-to-one correspondence. When the fan blade 31 is in the working position, the connecting member 32 is extended along the radial direction of the first support member 1 or the second support member 2, that is, the distance between the first connecting axis 11 and the second connecting axis 21 is the smallest; when the fan blade 31 is in the storage position, the connecting member 32 deviates from the radial direction of the first support member 1 or the second support member 2, that is, the distance between the first connecting axis 11 and the second connecting axis 21 is the largest.

[0049] In the embodiments of the present application, Figure 4 As shown, the connecting member 32 is sleeved on the first connecting shaft 11 through the through hole, that is, the connecting member 32 is rotatably connected to the first connecting shaft 11; the connecting member 32 is sleeved on the second connecting shaft 21 through the sliding groove 321, that is, the connecting member 32 is slidably connected to the second connecting shaft 21, wherein the sliding groove 321 extends along the length direction of the connecting member 32. When the fan blade 31 is in the storage position, the second connecting shaft 21 is located at the end of the sliding groove 321 away from the fan blade 31; Figure 2 As shown, when the fan blade 31 is in the working position, the second connecting shaft 21 is located at the end of the sliding groove 321 close to the fan blade 31. The distance of the sliding groove 321 can limit the rotation angle of the fan blade 31, and thus no additional rotation angle limiting device is required.

[0050] As an alternative embodiment, the connecting member 32 is sleeved on the second connecting shaft 21 through a through hole, that is, the connecting member 32 is rotationally connected to the second connecting shaft 21; the connecting member 32 is sleeved on the first connecting shaft 11 through a slide groove 321, that is, the connecting member 32 is slidingly connected to the first connecting shaft 11, wherein the slide groove 321 extends along the length of the connecting member 32. When the fan 31 is in the storage position, the first connecting shaft 11 is located at the end of the slide groove 321 away from the fan 31; when the fan 31 is in the operating position, the first connecting shaft 11 is located at the end of the slide groove 321 closer to the fan 31.

[0051] The shape of the fan blade 31 is not limited and may be an arc-shaped plate, a rectangular plate, or a corrugated plate, etc. In the embodiment of the present application, the fan blade 31 is an arc-shaped plate.

[0052] In order to improve the stability of the wind guiding by the fan blade, the fan blade assembly also includes a limiting portion, which is arranged on the first support member 1 and / or the second support member 2. The limiting portion is detachably connected to the fan blade portion 3. When the fan blade portion 3 is in the working position, the limiting portion cooperates with the fan blade portion 3 to limit the rotation of the first support member 1 relative to the second support member 2.

[0053] In the embodiment of the present application, the connecting member 32 is rotationally connected to the first connecting shaft 11 and slidably connected to the second connecting shaft. The connecting member 32 can move a predetermined distance along the axial direction of the first connecting shaft 11. The limiting portion is a groove provided on the first support member 1 and / or the second support member 2. When the fan unit 3 is in the operating position, the connecting member 32 is pressed so that at least a portion of the connecting member 32 extends into the groove. In other words, the connecting member 32 is pressed into engagement with the first support member 1, restricting rotation of the connecting member 32 relative to the first support member 1 and, in turn, restricting sliding of the connecting member 32 relative to the second support member 2.

[0054] As an alternative embodiment, the connecting member 32 is rotationally connected to the second connecting shaft 21 and slidably connected to the first connecting shaft 11. The connecting member 32 can move a predetermined distance along the axial direction of the second connecting shaft 21. The stopper is a groove provided on the second support member 2. When the fan unit 3 is in the operating position, the connecting member 32 is pressed so that at least a portion of the connecting member 32 extends into the groove. In other words, the connecting member 32 is pressed into engagement with the second support member 2, restricting rotation of the connecting member 32 relative to the second support member 2 and, in turn, restricting sliding of the connecting member 32 relative to the first support member 1.

[0055] Combine Figures 5 to 8 As shown, according to another specific embodiment of the present invention, a shell assembly is provided, the shell assembly includes a fan blade assembly, and the fan blade assembly is the fan blade assembly in the above embodiment.

[0056] In an exemplary embodiment of the present application, a housing assembly includes a housing 5 and a spliced ​​volute 7. The housing 5 has duct side panels for forming an air duct, the duct side panels including a volute side panel 4 having an opening. The spliced ​​volute 7 is connected to the housing 5 and has a blocked position and a ready-to-assemble position. When the spliced ​​volute 7 is in the blocked position, the spliced ​​volute 7 and the volute side panel 4 form a volute enclosure, and at least a portion of the spliced ​​volute 7 protrudes from the exterior of the housing. The fan assembly is disposed within the air duct.

[0057] It should be noted that the air duct includes a volute duct and an air supply duct. The duct side panels include a volute side panel 4 and an air supply side panel 8. The air supply side panel 8 is connected to the volute side panel 4 along the length of the housing 5. The volute side panels 4, the spliced ​​volute 7, the air collecting plate, and the volute side panels 4 corresponding to the housing bottom plate together form the volute duct. The fan assembly is located within the volute duct. The volute side panel 4 refers to the curved plate located within the housing 5 that forms the volute duct. The volute duct forms at least part of the fan duct. The air supply side panel 8 and the air collecting cover enclose the air supply duct.

[0058] It should be further explained that the size of the housing 5 is limited by the installation space, which in turn limits the size of the air duct, thereby affecting the air output. The housing assembly is now designed as a spliced ​​structure, and the position of the spliced ​​volute 7 can be controlled according to the installation environment, so that even if the size of the housing 5 is increased, it will not be restricted by the installation space.

[0059] As an alternative embodiment, the housing assembly includes a volute side plate 4 and a spliced ​​volute 7 , that is, the volute side plate 4 and the spliced ​​volute 7 are spliced ​​to form the main body housing.

[0060] Furthermore, the housing assembly further includes a motor 6, which is connected to the housing 5, and an output shaft of the motor 6 is connected to the fan blade assembly to drive the fan blade assembly to rotate.

[0061] In the embodiment of the present application, the motor 6 is connected to the bottom of the housing 5. A support disc 61 is mounted on the drive shaft of the motor 6. The support disc 61 is provided with a plurality of support rods 62, which are spaced apart circumferentially around the support disc 61. The support disc 61 is connected to the first support member 1 via the plurality of support rods 62, enabling the motor 6 to drive the fan assembly to rotate. When the fan unit 3 switches between the storage position and the operating position, the first support member 1 remains stationary, while the second support member 2 is operated to rotate relative to the first support member 1.

[0062] As an alternative embodiment, the motor 6 is connected to the bottom of the housing 5. A support disc 61 is mounted on the drive shaft of the motor 6. The support disc 61 is provided with a plurality of support rods 62, which are spaced apart circumferentially around the support disc 61. The support disc 61 is connected to the second support member 2 via the support rods 62, enabling the motor 6 to drive the fan assembly to rotate. When the fan unit 3 switches between the stowed position and the operating position, the second support member 2 remains stationary, and the first support member 1 is operated to rotate relative to the second support member 2.

[0063] According to another specific embodiment of the present invention, a ceiling device is provided, comprising a housing assembly, which is the housing assembly described in the above embodiment. The ceiling appliances include, but are not limited to, kitchen air conditioners, non-kitchen air conditioners, bathroom heaters, fresh air blowers, and ventilation fans.
