Description

Technical Field

[0001] The utility model relates to the technical field of fan manufacturing, and particularly relates to a combined fan cover and a fan. Background Art

[0002] When a cylindrical fan is installed, one end of it is connected to a ventilation duct, and the other end is connected to an air filter box. Generally, the fan is fixed on the air filter box through a fixing plate. The fixing plate for installation and the shell are divided into two structural forms: integral type and split type. Both structural forms have their defects during installation. When a suspended fan is installed, a fixing plate generally needs to be added. During the use of the fan, continuous vibration will occur. The fixing plate plays a role in supporting the fan shell and ensuring that the shell does not crack during the operation of the fan. In addition, both the integral and split fixing plates will increase the installation cost of the fan. For the suspended installation, part of the fan needs to be embedded into the box body, and sealant needs to be applied to fill the gaps of the fixing plate after installation, increasing the installation cost. Now, a fan installation method without a fixing plate is needed to reduce the installation difficulty and cost of the fan while ensuring the firm installation of the fan.

[0003] The patent with the existing publication number CN210769528U discloses a fan shell convenient for manual cleaning, including: an installation plate assembly, and further including two symmetrically arranged semi-cylindrical shell assemblies, the semi-cylindrical shell assemblies are slidably connected to the installation plate assembly; both ends of the installation plate assembly are respectively connected with push-pull rod assemblies, and the inner ends of the push-pull rod assemblies are connected to the corresponding semi-cylindrical shell assemblies, suitable for driving the semi-cylindrical shell assemblies to move left and right. The same fixing plate is provided on this fan shell for fan installation, increasing the installation difficulty and cost of the fan. Summary of the Utility Model

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment 1

[0032] As Figures 1 - 7 shown, this embodiment discloses a combined fan cover, which includes a plurality of shells 101. The plurality of shells 101 are combined around an axis to form a cover body. The shell 101 includes a cover wall 11, a mounting bracket 12, and a longitudinal beam 14. The mounting bracket 12 is arranged at one end of the cover wall 11 and is perpendicular to the cover wall 11. The longitudinal beam 14 is arranged on the outer side wall of the cover wall 11, and one end of the longitudinal beam 14 is connected to the mounting bracket 12. By installing the shells 101 separately, the installation difficulty is reduced. The mounting bracket 12 on the shell 101 plays a supporting role, and the installation fixing plate is omitted, reducing the use cost.

[0033] Furthermore, the shell 101 further includes a reinforcing rib 13. One end of the reinforcing rib 13 is connected to the mounting bracket 12, and the other end is connected to the cover wall 11, which is used to improve the connection strength between the mounting bracket 12 and the cover wall 11 and prevent the joint from cracking. A plurality of reinforcing ribs 13 are evenly arranged around the axis of the cover body.

[0034] Preferably, the cover body is set to be one of a circle or a polygon, and is selected according to the specific shape of the ventilation system at the installation position to adapt to different cold and warm air systems.

[0035] Even further, the shell 101 further includes a connecting piece 15. The connecting piece 15 is arranged at the end of the cover wall 11 adjacent to the mounting bracket 12. The connecting piece 15 is provided with a through hole 16. The connecting piece 15 and the through hole 16 are used for bolt connection to combine another or multiple shells 101 to form the wind cover. The connection method is simple, and the weight of each shell 101 is reduced, thereby reducing the installation difficulty.

[0036] Preferably, the shell 101 further includes an end plate 17. The end plate 17 is arranged at the other end of the cover wall 11. The other end of the longitudinal beam 14 is connected to the end plate 17. The end plate 17 is provided with bolt holes for connecting a mesh cover or docking a pipeline. The fan cover body can be used as a part of the pipeline, reducing the use cost.

[0037] Preferably, a plurality of longitudinal beams 14 are arranged around the axis of the cover body, and cooperate with the mounting bracket 12 and the end plate 17 to form a grid-like structure, which strengthens the cover wall 11, prevents the cover wall 11 from deforming, and reduces the vibration during operation.

[0038] More preferably, the housing 101 further includes a protruding portion 18, which is disposed on the outer sidewall of the cover wall 11 and is perpendicular to the longitudinal beam 14. The protruding portion 18 is formed by bending the sheet metal on the housing 101, which increases the strength of the cover wall 11 without increasing the cost and prevents the cover wall 11 from deforming during installation and use.

[0039] More preferably, the mounting brackets 12, the end plates 17 and the connecting members 15 are connected end to end to form a closed shape around the edge of the cover wall 11, forming a grid-like structure on the edge and the outer wall of the cover wall 11, so as to comprehensively strengthen the cover wall 11 and improve the... of the cover wall 11.

[0040] More preferably, the cross-section of the longitudinal beam 14 is set to a U shape to increase the strength of the longitudinal beam 14.

[0041] More preferably, the thickness of the mounting bracket 12 is greater than twice the thickness of the cover wall 11. Increasing the thickness of the mounting bracket 12 can improve the strength of the connection to the wall or the box body and prevent the mounting bracket 12 from cracking.
