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.

[0064] Combine Figures 1 to 9 As shown, according to a specific embodiment of the present utility model, a housing assembly is provided.

[0065] Specifically, the shell assembly includes a shell 10, a spliced ​​volute 20 and a wind wheel 30. The shell 10 has a volute side plate 12 for forming an air duct 11. The volute side plate 12 has a first opening 101. The spliced ​​volute 20 has a blocking position for blocking at least part of the first opening 101, and the spliced ​​volute 20 has an assembly position. When the spliced ​​volute 20 is in the blocking position, at least part of the spliced ​​volute 20 is protruding from the outside of the shell 10; the wind wheel 30 is arranged in the air duct 11, and the wind wheel 30 has a storage position contracted in the radial direction, and the wind wheel 30 has a working position extended in the radial direction.

[0066] Combine Figure 2 and Figure 4 As shown, when installing the shell assembly, the spliced ​​volute 20 is installed in the blocking position to at least partially block the first opening 101, so that the shell assembly breaks through the problem of low air output caused by installation space limitations. When the spliced ​​volute 20 is in the blocking position, the spliced ​​volute 20 is connected to the shell 10 and seals the first opening 101. This arrangement increases the air output of the shell assembly, improves the sealing performance of the shell assembly, and reduces the installation difficulty of the shell assembly, solving the problem of low air output due to limited installation space in the prior art shell assembly, and effectively improving the practicality of the shell assembly. At the same time, the wind wheel 30 can be contracted or extended in the radial direction. When the wind wheel 30 is in the storage position, the space occupied by the wind wheel 30 can be reduced. When the wind wheel 30 is in the extended position, the air output and air output efficiency can be increased.

[0067] Among them, the shell 10 is the outer shell of the Yuba main unit, and the volute side plate 12 of the air duct 11 is set in the shell 10. The air duct 11 and the shell 10 are two independently set components. Of course, the volute side plate 12 can also be set as a plate-like structure, and the volute side plate 12 and the side wall and bottom plate of the shell 10 are surrounded to form the air duct 11. Specifically, a wind collecting cover is set on the side of the shell 10 opposite to the bottom. The wind wheel 30 is at least partially set in the volute side plate 12. The wind wheel 30 and the volute air duct 11 at least constitute the fan structure.

[0068] The assembly position includes a first assembly position. When the spliced ​​volute 20 is in the first assembly position, the spliced ​​volute 20 is separated from the housing 10. In some embodiments, the spliced ​​volute can be installed on an installation base. The installation base is a ceiling structure, which includes a keel, a gusset plate, a wooden block, a large board, a gypsum ceiling, and other structures.

[0069] Furthermore, the position to be assembled includes a second position to be assembled, and the spliced ​​volute 20 is movably connected to the shell 10 so that the spliced ​​volute 20 can be moved to the blocking position or the second position to be assembled, wherein when the spliced ​​volute 20 is in the second position to be assembled, the spliced ​​volute 20 is located inside the shell 10.

[0070] Furthermore, the position to be assembled includes a third position to be assembled. When the spliced ​​volute 20 is located at the third position to be assembled, at least part of the spliced ​​volute 20 is connected to the volute side plate 12 and deformed into the shell 10 toward the inside of the shell 10.

[0071] Furthermore, when the splicing volute 20 is located at the first position to be assembled, the operating housing 10 moves toward the splicing volute 20 until the splicing volute 20 is in the blocking position.

[0072] Furthermore, when the spliced ​​volute 20 is located at the third position to be assembled, the spliced ​​volute 20 is configured to be made of a flexible material.

[0073] Furthermore, when the spliced ​​volute 20 is located at the second position to be assembled, the spliced ​​volute 20 is slidably connected to the housing 10 .

[0074] The housing assembly further includes a guide assembly 40, through which the splicing volute 20 slides to the blocking position and the ready-to-assemble position along the height direction of the housing 10. Specifically, the guide assembly 40 can guide the splicing volute 20 when it is located at the first ready-to-assemble position and switches to the blocking position.

[0075] In other embodiments, the spliced ​​volute 20 is detachably connected to at least one of the housing 10 and the volute side panel 12 via a snap assembly.

[0076] Furthermore, when the spliced ​​volute 20 is in the blocking position, at least part of the spliced ​​volute 20 is protruding outside the housing 10. This arrangement increases the air output of the housing assembly, solving the problem of low air output due to limited installation space in the prior art housing assembly.

[0077] In order to achieve the assembly effect of the shell assembly, the shell assembly also includes a guide assembly 40, and the spliced ​​volute 20 slides to the blocking position and the position to be assembled through the guide assembly 40, which improves the convenience of installing the shell assembly.

[0078] Optionally, the spliced ​​volute 20 slides along the height direction of the housing 10 to the blocking position and the position to be assembled through the guide assembly 40. This arrangement makes the operation of the housing assembly more convenient during installation.

[0079] In an exemplary embodiment of the present application, the spliced ​​volute 20 slides along the height direction of the shell 10 to the blocking position and the assembly position through the guide assembly 40, and the guide assembly 40 includes a first guide member 41 and a second guide member 42 that cooperate with each other. One of the first guide member 41 and the second guide member 42 is arranged on the shell 10, and the other of the first guide member and the second guide is connected to the spliced ​​volute 20.

[0080] Among them, the first guide member 41 and the second guide member 42 can be, but are not limited to, set as sliders and slide grooves, guide rails and pulleys, etc., as long as they can achieve cooperative sliding. When installing the shell assembly, first install the spliced ​​volute 20 in the position to be assembled on the installation base, and then slide the spliced ​​volute 20 along the height direction of the shell 10 through the first guide member 41 and the second guide member 42 until the spliced ​​volute 20 is located in the blocking position connected to the shell 10 and the first opening 101 is at least partially blocked. Through this design, the shell assembly can not only realize the detachable setting of the spliced ​​volute 20, but also can switch between the blocking position and the position to be assembled as needed, which provides great convenience for the installation, disassembly and maintenance of the shell assembly. At the same time, this design can also ensure the sealing between the spliced ​​volute 20 and the shell 10, prevent gas leakage, and improve the performance and reliability of the shell assembly.

[0081] In a preferred embodiment of the present application, one of the first guide member 41 and the second guide member 42 includes a groove 411, and the other of the first guide member 41 and the second guide member 42 includes a sealing member 421 that cooperates with the groove 411. The sealing member 421 is preferably configured as a sealing plate, and may also be configured as a raised ridge, a slide rail, etc., as long as the sealing effect can be achieved. When the shell assembly is installed, the groove 411 guides the sealing member 421 that cooperates with it, so that the spliced ​​volute 20 moves to the sealing position. When the shell assembly needs to be assembled or maintained, the sealing member 421 moves in the opposite direction, thereby driving the spliced ​​volute 20 to move in the opposite direction, and moving the spliced ​​volute 20 to the position to be assembled. The groove 411 guides and limits the sealing member 421, thereby reducing the difficulty of installing the shell assembly.

[0082] Optionally, the spliced ​​volute 20 has a notch arranged toward the inner side of the shell 10. This arrangement increases the air outlet in the air duct 11 and improves the practicality of the shell assembly.

[0083] In order to achieve the assembly effect that the spliced ​​volute 20 can be switched between the blocking position and the ready-to-assemble position, the Figure 4 As shown, the spliced ​​volute 20 includes a spliced ​​volute body 21 extending along the length of the housing 10. Two spliced ​​side panels 22 are provided on either side of the spliced ​​volute body 21 in the lengthwise direction. The two spliced ​​side panels 22 and the spliced ​​volute body 21 form a volute structure with a notch on one side. A blocking member 421 extends circumferentially along the edge of the notch. This arrangement increases the airflow of the housing assembly while ensuring stable airflow.

[0084] Combine Figure 6 As shown, in a preferred embodiment of the present application, the blocking member 421 is provided with a limiting protrusion 4212, so that the installation and positioning of the shell assembly can be achieved.

[0085] Combine Figure 6 As shown, in a preferred embodiment of the present application, a first flange structure 4211 is provided along one side of the length of the blocking member 421. A limiting protrusion 4212 and the first flange structure 4211 are provided on opposite sides of the length of the blocking member 421. When the spliced ​​volute 20 is in the blocking position, the first flange structure 4211 is located on the outside of the bottom of the housing 10. This arrangement strengthens the connection stability between the housing 10 and the blocking member 421. Once the connection is stable, the first flange structure 4211 serves to limit the height of the housing 10.

[0086] Combine Figure 2 、 Figure 4 and Figure 6As shown, in a specific embodiment of the present application, the plane where the first flange structure 4211 is located is arranged at an angle to the plane where the blocking member 421 is located. When the spliced ​​volute 20 is in the blocking position, the first flange structure 4211 is located on the outside of the bottom of the housing 10, which helps to achieve quick and accurate positioning during installation, making the installation process more convenient.

[0087] Combine Figure 6 As shown, in a preferred embodiment of the present application, a groove 411 is provided at the edge of the first opening 101, which is recessed toward the inside of the housing 10. When the spliced ​​volute 20 is in the blocked position, at least a portion of the blocking member 421 extends into the groove 411. This arrangement enhances the sealing performance of the spliced ​​volute 20 in the blocked position through the blocking member 421 and the groove 411, thereby improving the reliability of the housing assembly.

[0088] In order to further optimize the connection stability of the spliced ​​volute 20 when it is in the blocking position, at least one limiting section 102 is provided on the groove wall of the groove 411, and a limiting space 103 is formed between the limiting section 102 and the groove 411 (combined with Figure 4 and Figure 5 As shown), when the spliced ​​volute 20 is in the blocking position, part of the blocking member 421 extends into the limiting space 103 (combined with Figure 2 and Figure 3 This arrangement can better achieve the fixing and sealing effect of the blocking member 421. This design can effectively prevent various problems such as gas leakage caused by unstable connection between the groove 411 and the blocking member 421.

[0089] Combine Figure 2 and Figure 4 As shown, in a preferred embodiment of the present application, at least two limiting sections 102 are provided on either side of the width direction of the mating groove 411, and the two limiting sections 102 are arranged opposite each other. One end of each limiting section 102 is connected to the housing 10, and the other end of each limiting section 102 extends away from the housing 10 along the length direction of the mating groove 411. This arrangement further improves the connection stability between the groove 411 and the blocking member 421, and optimizes the sealing effect of the housing assembly.

[0090] Combine Figure 4 As shown, in a preferred embodiment of the present application, the housing 10 has a second flange structure 104, which is arranged along the circumference of the housing 10. The second flange structure 104 is provided with at least one limiting groove 1041, which is provided in cooperation with the limiting protrusion 4212. Figure 4 and Figure 5As shown, when the spliced ​​volute 20 is in the blocking position, the limiting protrusion 4212 on the blocking piece 421 is located in the limiting groove 1041 on the second flange structure 104, limiting the blocking piece 421, making the connection between the groove 411 and the blocking piece 421 more stable, thereby improving the reliability of the shell assembly.

[0091] In a preferred embodiment of the present application, the housing 10 is provided with a second flange structure 104, which is arranged along the circumference of the housing 10 to enhance the housing's stability and structural strength. The second flange structure 104 is provided with multiple retaining grooves 1041, and the blocking member 421 is provided with multiple retaining protrusions 4212. Each retaining groove 1041 cooperates with each retaining protrusion 4212 to achieve precise positioning and fixation. Specifically, the second flange structure 104 can be a portion of the housing 10, formed by adding additional material or structure to the edge of the housing. This design helps improve the overall rigidity and deformation resistance of the housing. The retaining grooves 1041 can be grooves on the second flange structure 104, with their shape and size matching the retaining protrusions 4212 to ensure a tight fit between them. The retaining grooves 1041 can be evenly distributed along the second flange structure 104, providing accurate positioning and fixing points for the retaining protrusions 4212. This design not only improves the stability of the overall structure but also facilitates quick and accurate positioning during installation.

[0092] In a preferred embodiment of the present application, when the spliced ​​volute 20 is in the blocking position, the first flange structure 4211 and the limiting protrusion 4212 extend in opposite directions away from the blocking member 421. This arrangement further improves the limiting strength of the spliced ​​volute 20 and the shell 10 in the horizontal and numerical directions.

[0093] like Figure 7 As shown, the wind wheel 30 is located in the storage position, and the wind wheel 30 is located in the housing 10. This saves the internal space of the housing 10.

[0094] When the wind wheel 30 is located at the working position, part of the structure of the wind wheel 30 is located outside the first opening 101 .

[0095] like Figure 8 、 Figure 9As shown, the wind wheel 30 includes: a support portion 31; a blade portion 33, which is movably connected to the support portion 31 so that the blade portion 33 has a storage position in which it is contracted in the radial direction, and an operating position in which it is extended in the radial direction. The blade portion 33 can contract or extend in the radial direction. When the wind wheel 30 is in a non-operating state, the blade portion 33 is driven to contract in the radial direction to reduce the space occupied by the blade portion 33. When the wind wheel 30 is in an operating state, the blade portion 33 is driven to extend in the radial direction, thereby improving the air output efficiency and air volume and reducing noise.
