When the first drive unit 20 is connected to the second support portion 12, the first output shaft 21 of the first drive unit 20 is connected to the second chassis 121.

[0067] Furthermore, the blades 322 are arc-shaped plate-like structures. The blades 322 are arranged in sequence in one direction.

[0068] According to another aspect of the present invention, a housing assembly is provided, comprising a blade assembly, the blade assembly being the blade assembly of the aforementioned embodiment. The blade assembly comprises: a support portion 10; a first drive portion 20, the first drive portion 20 being disposed on the support portion 10; and a blade portion 30, the blade portion 30 being movably connected to the support portion 10, the first drive portion 20 driving the blade portion 30 to be movably disposed so that the blade portion 30 has a radially retracted storage position and a radially extended operating position.

[0069] like Figure 6 、 Figure 8 As shown, the shell assembly includes: a volute 40, the volute 40 has an opening 41; a splicing body 50, the splicing body 50 has a blocking position connected to the volute 40, when the splicing body 50 is in the blocking position, at least part of the splicing body 50 protrudes from the outside of the opening, and the splicing body 50 has a separation position separated from the volute 40 or a storage position stored in the shell assembly; wherein, the fan blade assembly is arranged in the volute 40.

[0070] Furthermore, the shell assembly also includes: a second drive unit 60, which is arranged in the shell assembly. In this embodiment, the second drive unit 60 is fixedly installed on the bottom wall of the shell assembly, and the second output shaft 61 of the second drive unit 60 is connected to the support unit 10. The second drive unit 60 is used to drive the support unit 10 to drive the fan blade assembly to rotate.

[0071] Specifically, the second output shaft 61 of the second driving unit 60 is connected to the second chassis 121 , and the second driving unit 60 is used to drive the second chassis 121 to drive the fan blade assembly to rotate.

[0072] like Figure 7 A second through hole 125 is provided on the second chassis 121 , and the second output shaft 61 of the second driving portion 60 is disposed in the second through hole 125 . The second through hole 125 is communicated with the first through hole 115 .

[0073] Specifically, the first output shaft 21 of the first drive unit 20 and the second output shaft 61 of the second drive unit 60 both extend into the second through hole 125. When the second drive unit 60 is in operation, the second output shaft 61 drives the second chassis 121 to rotate. This, in turn, drives the first output shaft 21 to rotate, which in turn drives the first chassis 111 to rotate. In other words, the second output shaft 61 of the second drive unit 60 can drive the entire fan assembly to rotate. In this embodiment, the first output shaft 21 and the second output shaft 61 are in contact. In other embodiments, a gap may be provided between the first output shaft 21 and the second output shaft 61.

[0074] In this embodiment, the first driving part 20 and the second driving part 60 may be motors.

[0075] The operating steps for installing and using the fan blade assembly are as follows: first, control the second driving part 60 to be in a non-working state, at which time the second chassis 121 and the second support member 122 are in a stationary state, operate the first driving part 20 to rotate in the first direction, drive the first chassis 111 to rotate in the first direction, and then drive the first support member 112 to rotate in the first direction, so that the fan blade 32 shrinks to the storage position along the radial direction to save space and facilitate the placement of the fan blade assembly in the volute 40. After the fan blade assembly in the storage position is placed in the volute 40, operate the first driving part 20 to rotate in a second direction opposite to the first direction, drive the first chassis 111 to rotate in the second direction, and then drive the first support member 112 to rotate in the second direction, so that the fan blade 32 extends to the working position along the radial direction to increase the air outlet efficiency and air outlet volume.

[0076] When the fan blade assembly is located in the volute 40 and is in the working position, the second drive unit 60 is controlled to work, and the first drive unit 20 is not working. The second output shaft 61 of the second drive unit 60 drives the second chassis 121 and the second support member 122 to rotate. Since the second output shaft 61 is in contact with the first output shaft 21, it drives the first chassis 111 and the first support member 112 to rotate, so that the first support part 11 and the second support part 12 are relatively stationary. Therefore, the second drive unit 60 drives the entire fan blade assembly to rotate through the second output shaft 61 to achieve blowing.

[0077] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0078] (1) The fan blade portion 30 can shrink and expand along the radial direction, which means that the size and angle of the fan blade can be adjusted as needed to adapt to different working environments or needs.

[0079] (2) Since the fan blade portion 30 can be retracted into a more compact shape, the fan blade assembly is easier to store and transport when not in use, reducing space occupation.

[0080] (2) The fan blade portion 30 can provide a larger surface area when in the working position to increase wind output, while reducing air resistance when in the storage position, which may help improve overall efficiency.

[0081] (4) At least part of the fan blade assembly is located in the volute 40, and the splicing body 50 is detachably connected to the volute 40, so that the splicing body 50 in the blocked position increases the air output, and the splicing body 50 in the separated position saves space.

[0082] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures.
