Description

Technical Field

[0001] This application relates to the field of fan mounting technology, and in particular to a fan with a cage. Background Technology

[0002] In the existing technology, the commonly used iron cage built-in fans on the market are mainly divided into two structural forms.

[0003] One type is the integrated iron cage with built-in fans, where the entire structure is packaged and transported as a complete unit after production. However, this integrated structure results in a relatively large packaging volume for the iron cage with built-in fans, occupying more transportation space and significantly increasing transportation costs. In logistics transportation, costs are closely related to the volume and weight of the goods. Larger packaging volume means more transportation resources are needed, such as vehicle space and warehouse area, thus increasing transportation costs. This negatively impacts the product's market competitiveness.

[0004] Another type is the detachable cage-mounted fan, designed to address the issue of excessive bulk in integrated cage structures. This type of detachable cage-mounted fan is typically installed using screws. In actual use, customers need to assemble it themselves, but the screw installation method is cumbersome, requiring tools to tighten multiple screws. Furthermore, inconsistent screw tightening and incorrect installation sequence are common problems, causing significant inconvenience, increasing installation time and labor intensity, reducing user experience, and limiting the market adoption of detachable cage-mounted fans.

[0005] Therefore, the existing cage-mounted fan structures on the market currently have problems in terms of transportation cost control and customer installation convenience, and a new type of cage-mounted fan structure that can balance transportation cost and installation convenience is needed to meet market demand.

[0054] The present application will be further described below with reference to the accompanying drawings, but the scope of protection of the present application is not limited to the following description.

[0055] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0056] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0057] The following embodiments of this application provide a fan with a cage, which solves the problems of existing iron cage built-in fans having a large packaging volume and high transportation costs due to the integrated structure, and the problems of detachable structures relying on screw installation and cumbersome customer assembly.

[0058] This application provides a fan with a cage, employing a design where the motor assembly and support mechanism interlock. This structure requires no additional screws and is stable and reliable after installation, effectively avoiding the problems of screw-dependent installation and cumbersome customer assembly associated with disassembly-type structures. Installation is convenient, and the overall structure boasts high strength. The cage housing adopts a split structure (two or more pieces), resulting in a small packaging volume, strong impact resistance, and resistance to deformation. It is also process-friendly, easy to manufacture, and its dimensions are easily controlled, while remaining inexpensive. Furthermore, the cage housing is installed using a snap-fit ​​connection, eliminating the need for screws and ensuring convenient and user-friendly installation. After installation, the overall structure is stable, reliable, and aesthetically pleasing. The support components are fixed to the motor body via universal joints (two or more joints), saving customers installation and wiring costs, reducing packaging volume, and lowering transportation costs.

[0059] The following will describe in detail, with reference to the accompanying drawings, the principle of a fan with a cage according to this embodiment, so that those skilled in the art can understand the fan with a cage according to this embodiment without creative effort.

[0060] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The images shown are respectively a three-dimensional structural diagram of the fan with a cage as described in the embodiments of this application, an exploded view of the fan with a cage as described in the embodiments of this application, a structural diagram of the cage housing and fan structure of the fan with a cage as described in the embodiments of this application, a structural diagram of the motor assembly and support mechanism combination of the fan with a cage as described in the embodiments of this application, a front view of the support rod in one embodiment of this application, a structural diagram of the first housing in one embodiment of this application, and a detailed diagram of the first housing and support mechanism in one embodiment of this application, showing a first installation scheme. Figure 1 , Figure 2 and Figure 3 As shown, the fan 1 with a cage includes: a motor assembly 100, a cage housing 200, a support mechanism 300, and fan blades 400.

[0061] In one embodiment, the cage housing 200 is detachably connected to the motor assembly 100. The cage housing 200 includes at least two first housings 210; adjacent first housings 210 are detachably connected to the support mechanism 300 to form an annular sidewall of the outer shell.

[0062] The fan blade 400 is at least partially located in the interior space of the annular sidewall.

[0063] The first housing 210 is connected to the support mechanism 300 via a first connecting portion 220. The first connecting portion 220 is located on the edge of the first housing 210, and the support mechanism 300 has a second connecting portion 330. The first connecting portion 220 of the first housing 210 is fixedly connected to the second connecting portion 330 of the motor assembly 100, so that the first housing 210 and the motor assembly 100 are mutually fixed and limited by the support mechanism 300.

[0064] The first housing 210 has a first connecting part 220 on each side that is connected to the support mechanism 300; each of the first housings 210 is fixedly connected to each other through the support mechanism 300 to form a closed annular sidewall.

[0065] The cage shell 200 can adopt an arc-shaped, strip-shaped, or L-shaped structure.

[0066] Specifically, the cage shell 200 adopts a split structure, that is, the cage shell 200 includes two or more first shells 210; and each first shell 210 has a first connecting part 220 at its vertical edge (i.e., at both sides of the first shell 210). The multiple first shells 210 are fixed and limited to each other by the first connecting parts 220 and the second connecting parts 330 on the support mechanism 300, so that each first shell 210 is detachably connected to each other (i.e., adjacent first shells 210 are detachably connected to the support mechanism 300) to form the annular sidewall of the shell.

[0067] The cage shell 200 can be arc-shaped, elongated, or L-shaped. It has locking features (such as second connecting parts 330) fixed to the support mechanism 300 on both sides of the vertical connecting arm, which is the first shell 210. Then, the first connecting part 220 can be engaged with the second connecting part 330 of the support mechanism 300 to splice multiple first shells 210 to form a closed cage shell 200 that is annular, circular, or multi-sided.

[0068] Therefore, the split structure adopted by the cage shell 200 (i.e., composed of two or more first shell pieces 210 spliced ​​together to form a closed annular cage) results in a small packaging volume, strong impact resistance, resistance to deformation, ease of manufacturing, convenient processing, easy size control, and low cost. Furthermore, the cage shell 200 uses a snap-fit ​​connection, eliminating the need for screws during installation, making installation convenient, providing a good user experience, and ensuring overall stability and a pleasing appearance after installation.

[0069] It should be noted that the cross-section of the vertical connecting arm here can be rectangular, C-shaped, or other structures, but is not limited to these two types, as long as it can be spliced ​​into a closed shape by multiple first shells 210.

[0070] Please continue reading. Figure 4 and Figure 7 .

[0071] In one embodiment, the motor assembly 100 includes a motor body 110. The motor body 110 is detachably connected to the fan blade 400, and the geometric centers of the motor body 110 and the fan blade 400 are located on the same reference axis.

[0072] The motor body 110 is detachably connected to the support mechanism 300 via a plurality of universal joints 120. The universal joints 120 are all disposed on the base 111 of the motor body 110 and are all disposed on the same plane.

[0073] Specifically, the central axes of the motor assembly 100 and the fan blade 400 are on the same baseline. A base 111 is provided on the motor body; the fan blade 400 is disposed in the opposite position to the base 111.

[0074] The support mechanism 300 is fixed to the motor body 110 via the universal joint 120 and can swing left and right to adapt to the installation of the outer cover structure. Simultaneously, it reduces the packaging volume, and thus, due to the movable connection of the universal joint 120, reduces the damage rate of the support frame upon impact.

[0075] Therefore, the support members can be installed and fixed on the motor body 110 via universal joints 120 (two or more), thereby saving customers installation and wiring costs; at the same time, the packaging volume is reduced, thereby reducing transportation costs.

[0076] In one embodiment, the support mechanism 300 includes at least two support members 310.

[0077] The first end of each support member is fixedly connected to the base 111 of the motor body 110, and the second end 312 of the support member is fixedly connected to the cage housing 200. The number of support members 310 corresponds to the number of first housings 210. The support members 310 can be C-shaped or L-shaped.

[0078] Specifically, in this embodiment, the support member 310 is preferably L-shaped. The first end 311 of each support member is fixedly connected to the base 111 of the motor body via a universal joint 120. The second end 312 of each support member is connected to the cage housing 200 and the protective net cover 230.

[0079] In one embodiment, the support member 310 has a second connecting portion 330 in the vertical direction corresponding to the first connecting portion 220 of the first housing 210. Each support member 310 includes an outer sidewall 323 near the motor body 110, an inner sidewall 324 opposite to the outer sidewall 323, and a first sidewall 321 and a second sidewall 322 adjacent to the outer sidewall 323. The first sidewall 321 and the second sidewall 322 are detachably connected to the first connecting portion 220.

[0080] In this embodiment, preferably, an L-shaped support member 310 is used. The vertical surface of the support member 310 has corresponding limiting features for the corresponding locking features of the cage shell 200. Each structural feature is similar, and the support member 310 is mounted on the motor body 110.

[0081] Specifically, the first end 311 of the L-shaped support is fixedly connected to the base 111 of the motor body via a universal joint 120; the second end 312 of the support is connected to the cage housing 200. The vertical direction of the L-shaped support 310 preferably adopts a cylindrical rod. The sides of this cylindrical rod are a first side wall 321, a second side wall 322, an inner side wall 324, and an outer side wall 323. The outer side wall 323 refers to the side wall of the support 310 rod closest to the motor body; the inner side wall 324 refers to the side wall position corresponding to the outer side wall 323; the first side wall 321 and the second side wall 322 are also side walls in corresponding directions, and the first side wall 321 and the second side wall 322 refer to the positions of the respective side walls corresponding to each first housing 210. That is, the first side wall 321 and the second side wall 322 are mutually secured and limited (e.g., engaged) with the first connecting portion 220 of each first housing 210.

[0082] In one embodiment, the cage housing 200 further includes a protective mesh cover 230. The protective mesh cover 230 is disposed at the lower end of the fan blade 400; the protective mesh cover 230 is fixed to the cage housing 200 by C-shaped arched brackets. The number of the arched brackets corresponds to the number of the first housings 210.

[0083] Specifically, the protective net cover 230 is placed at the lower part of the built-in fan (fan blade 400), and four C-shaped tubes support the four arms of the net cover to achieve the installation of the net cover. The protective net cover 230 is easy to install; it can be installed quickly and conveniently by overlapping.

[0084] In one embodiment, the second connecting portion 330 is disposed on the outer side wall 323, and at least two threaded holes 313 are provided at both ends of the outer side wall 323.

[0085] In one embodiment, the second connecting portion 330 and the first connecting portion 220 are fixedly positioned relative to each other; the threaded hole 313 is detachably connected by a fastener so that the first connecting portion 220 is fixedly connected to the outer wall 323 of the support member 310.

[0086] In this embodiment, two threaded holes 313 are preferably used; and these two threaded holes 313 are respectively disposed at both ends of the second connecting part 330.

[0087] Specifically, when the second connecting part 330 is disposed on the outer side wall 323, the first connecting part 220 of the first housing 210 is fixedly and limitedly connected to the second connecting part 330. In this embodiment, preferably, the first connecting part 220 can be a guide rail, and the second connecting part 330 can be a guide groove. That is, the first connecting part 220 is engaged in the second connecting part 330, and then a connecting piece 500 is placed over the second connecting part 330, and the nut is tightened into the threaded hole 313 to fix the connecting piece 500. At this time, the connecting piece 500 blocks the outside of the cage housing 200, and the connecting piece 500 and the cage housing 200 are fixed by tightening the hand-tightening nut. The material of the connecting piece 500 can be plywood, solid wood, iron sheet, square tube, etc.; the shape (e.g., long strip or L-shaped), appearance (e.g., rectangular or circular), paint and material can be changed according to requirements.

[0088] Please see Figure 8A , 8B 8C and 8C respectively show the product appearance after installation of the second installation scheme of the first housing and support mechanism in one embodiment of the present application, the position structure diagram of the second installation scheme of the first housing and support mechanism in one embodiment of the present application, and the front view of the support member in the second installation scheme of the present application.

[0089] In another embodiment, the second connecting portion 330 is disposed on the inner sidewall 324, and at least two threaded holes 313 are provided at both ends of the inner sidewall 324. The second connecting portion 330 and the first connecting portion 220 are fixedly positioned against each other; the threaded holes 313 are detachably connected by a fastener, so that the first connecting portion 220 is fixedly connected to the inner sidewall 324 of the support member 310.

[0090] Specifically, when the second connecting part 330 is disposed on the inner sidewall 324, the first connecting part 220 is limited and fixedly engaged in the second connecting part 330 of the inner sidewall 324, and can be further fixed with screws.

[0091] Please see Figure 9The diagram shows a third installation scheme of the first housing and support mechanism described in one embodiment of this application.

[0092] In another embodiment, the second connecting portion 330 is respectively disposed on the first sidewall 321 and the second sidewall 322.

[0093] The first connecting part 220 is fixedly and limitedly connected to the first side wall 321 and the second side wall 322, so that the first connecting part 220 is fixedly connected to the support member 310.

[0094] Specifically, when the second connecting portion 330 is disposed on the first sidewall 321 and the second sidewall 322, the first connecting portion 220 of the first housing 210 is engaged and fixed in the second connecting portion 330, thereby fixing the first housing 210 and the support mechanism 300 together. Then, each of the first housings 210 is connected in the same manner to form a closed annular structure.

[0095] In other words, the cage housing 200 uses locking features (such as the first connecting part 220 and the second connecting part 330 mutually limiting each other) to lock the left and right ends of the first housing 210 into the support member 310 of the support mechanism 300. The upper locking feature of the connecting arm can be similar to a longitudinal, elongated, or gourd-shaped notch. After the cage housing 200 is installed on the bracket from the outside in, and one ring of the first housing 210 is installed in place, a connecting piece 500 is provided on the outer end limiting position. This connecting piece 500 is installed on the outside of the cage housing 200 by a hand-tightening nut to restrict the cage housing 200 and ensure that it is installed in place.

[0096] Therefore, it can be seen that the cage shell 200 and the support mechanism 300 can be fixed in three ways, as described above. The underlying logic of all three is to restrict the locking mechanism to the support mechanism 300. One method is to fasten the first shell 210 to the support mechanism 300 from the outside in; another is to lock the first shell 210 to the support mechanism 300 from the inside out; and the third is to install and fix the first shell 210 to the support mechanism 300 from both sides. None of these three installation methods require additional screws from the customer. Furthermore, the structure is stable and secure after installation, and both of the above methods can be equipped with connecting pieces 500 or decorative pieces.

[0097] The following explanation uses the installation process of a fan with a cage as an example.

[0098] In this embodiment, preferably, a C-shaped cross-section cage shell and an L-shaped support are used; and four first shells and four support members are used; wherein the support members adopt a columnar structure.

[0099] Therefore, each of the first housings has a first connecting portion at both ends in the vertical direction, and the support member has a second connecting portion on the side wall of the vertical rod. The second connecting portions can be positioned in different ways, and different connection schemes can be formed depending on their positions.

[0100] The connection sequence of each component is as follows:

[0101] First, the cage housing is secured to the vertical connecting rod of the motor assembly support using the locking mechanism, and then pressed down into place. The first connecting part is then secured to the second connecting part. Next, the connecting pieces are sequentially fixed to the outside of the cage housing, and the outer cover and decorative piece are secured by hand-tightening nuts. Then, the protective mesh is placed under the fan blades of the built-in fan, with four C-shaped tubes supporting the four arms of the protective mesh to complete its installation. At this point, the entire fan with the cage is installed.

[0102] In summary, the fan with a cage provided in this application reduces packaging volume and improves logistics and warehousing efficiency through a quick-assembly and disassembly structural design. Simultaneously, the use of screwless or quick-release connections allows users to easily assemble it without tools, enhancing ease of use. Therefore, this application balances product stability and ease of installation while also optimizing supply chain costs.

[0103] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
