Description

Technical Field

[0001] This utility model relates to the field of industrial fan technology, and in particular to a quick-release industrial fan. Background Technology

[0002] Industrial fans can most efficiently drive a large amount of air movement, generating a huge air volume, creating a moving and circulating airflow field in the space, and effectively controlling the air circulation problem in industrial production workshops.

[0003] The area that an industrial fan can cover is directly related to its diameter. Large industrial fans offer a large coverage area, are easy to clean, and solve the problems of high noise and high energy consumption.

[0004] Industrial fans in the current technology usually connect the fan blades to the motor shaft, and drive the fan blades to rotate through the shaft. Because the blades are large, they also accumulate a lot of dust during operation. Moreover, the disassembly and assembly of the blades are relatively complicated, and the process of cleaning the blades is inconvenient. Utility Model Content

[0005] To address the problems of existing industrial fans, which typically connect fan blades to a motor shaft and drive the blades to rotate, resulting in large blades that accumulate dust during operation, and the complex disassembly and cleaning of the blades, this application provides a quick-release industrial fan, the specific solution of which is as follows.

[0006] A quick-release industrial fan includes a cover and multiple blades. The cover includes an upper cover and a lower cover, which are detachably connected. Both the upper and lower covers are provided with linkage posts, and linkage holes are provided in the linkage posts. The linkage holes are configured to correspond to the shape of a motor shaft. The motor shaft extends into the mating holes to form a transmission connection with the cover. An embedding groove is provided on the side of the cover, and the blades can be embedded in and confined within the embedding groove. The blades are arranged at equal intervals around the cover.

[0007] By adopting the above technical solutions, the design of the detachable connection between the upper and lower covers facilitates the maintenance and cleaning of the fan by users. At the same time, the cooperation between the linkage column and the linkage hole ensures a stable transmission connection between the motor shaft and the cover, improving the reliability of the fan operation. The embedded groove and blade embedding structure allows the blades to be firmly fixed on the cover.

[0008] Optionally, a block is provided at one end of the blade near the cover, the block is embedded in the embedding groove, and each block abuts against the other.

[0009] By adopting the above technical solution, the inserts are embedded in the groove to make the blades accurately positioned. At the same time, the design of each insert abutting against the others effectively prevents the blades from loosening or shifting when rotating at high speed, thereby improving the stability and reliability of the fan operation.

[0010] Optionally, the insert has a protruding positioning post, and a positioning cylinder is provided in the embedding groove corresponding to the positioning post. The positioning post can be embedded in the positioning cylinder and abut against the inner wall of the positioning cylinder.

[0011] By adopting the above technical solutions, the cooperation between the positioning post and the positioning cylinder can improve the installation stability of the blades in the embedding groove, preventing the blades from loosening or shifting during high-speed rotation, thereby improving the smoothness and reliability of the fan operation. Furthermore, the design of the positioning post abutting against the inner wall of the positioning cylinder further enhances the positioning accuracy of the blades, ensuring that the blades maintain a precise equidistant spacing after installation, thus optimizing the wind power output.

[0012] Optionally, each of the inserts is provided with two positioning posts, and two positioning holes are provided corresponding to the positioning posts, with the distance between the two positioning posts on each insert being the same.

[0013] By adopting the above technical solution, two positioning posts are set on the insert, which cooperate with the positioning cylinder in the embedding groove. This effectively restricts the position of the blade in the embedding groove, preventing the blade from shifting or loosening during high-speed rotation. In addition, the distance between the two positioning posts is the same, ensuring the consistency of blade installation, improving assembly efficiency, enhancing the overall structural balance, and reducing vibration and noise during operation.

[0014] Optionally, the upper cover has a mating post protruding towards the lower cover, and the lower cover has a mating hole corresponding to the mating post. The lower cover also has a mating post protruding towards the upper cover, and the upper cover has a mating hole corresponding to the mating post. The mating post can be embedded in the corresponding mating hole.

[0015] By adopting the above technical solution, the upper and lower covers are connected through the interlocking of mating posts and holes, enabling rapid assembly and disassembly and improving the installation efficiency of industrial fans. Simultaneously, this structural design ensures precise positioning between the upper and lower covers, enhancing the overall stability of the cover body and effectively preventing loosening or displacement during high-speed operation.

[0016] Optionally, both the upper and lower covers are provided with multiple threaded posts, which are arranged correspondingly to each other. Each threaded post is provided with a threaded hole, which passes through the threaded post.

[0017] By adopting the above technical solutions, the threaded post design allows for a detachable connection between the upper and lower covers via bolts, improving the ease of cover assembly. At the same time, the threaded hole penetrating the threaded post facilitates bolt installation and removal, further enhancing the maintenance efficiency of the industrial fan.

[0018] Optionally, the cover body is also provided with a plurality of reinforcing ribs, which are disposed between the threaded post and the linkage post. One end of the reinforcing rib is fixedly connected to the threaded post, and the other end of the reinforcing rib is fixedly connected to the linkage post.

[0019] By adopting the above technical solution, multiple reinforcing ribs are set on the cover. These ribs connect the threaded post and the linkage post, which can effectively improve the structural strength of the cover and prevent deformation or damage caused by uneven stress during high-speed rotation. At the same time, the setting of reinforcing ribs can also optimize the stress distribution inside the cover and extend its service life.

[0020] Optionally, the blade is provided with a mesh rib, which is arranged along the length direction of the blade.

[0021] By adopting the above technical solutions, the mesh reinforcement can significantly improve the structural strength of the blades and effectively prevent blade deformation during high-speed rotation. Furthermore, the mesh reinforcement design can also optimize airflow distribution and reduce operating noise to a certain extent, thereby improving the overall performance and service life of the industrial fan.

[0022] In summary, this application has at least the following beneficial effects:

[0023] This application addresses the problem that existing industrial fans typically connect the fan blades to the motor shaft, driving the blades to rotate. Due to the large size of the blades, they accumulate a lot of dust during operation, and the disassembly and assembly of the blades is quite complex, making the blade cleaning process inconvenient. This application improves the convenience of blade cleaning by providing easily removable upper and lower covers, making it easier to remove the blades from the upper and lower covers for cleaning.

[0030] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] A quick-release industrial fan, such as Figure 1 and Figure 2 As shown, the device includes a cover 1 and multiple blades 2. The cover 1 includes an upper cover 11 and a lower cover 12, which are detachably connected. Both the upper cover 11 and the lower cover 12 are provided with a linkage post 13, and a linkage hole 131 is provided within the linkage post 13. The linkage hole 131 corresponds to the shape of the motor shaft. The motor shaft extends into a mating hole 17 to form a transmission connection with the cover 1. An embedding groove 14 is provided on the side of the cover 1, and the blades 2 can be embedded in and confined within the embedding groove 14. The blades 2 are arranged at equal intervals around the cover 1. By adopting the above technical solution, the motor shaft is typically as follows: Figure 1 The irregular shape of the cover 1 allows it to rotate. When the blade 2 needs to be disassembled, the upper cover 11 and the lower cover 12 can be removed for disassembly and cleaning, making disassembly and cleaning more convenient.

[0032] like Figure 2 and Figure 3 As shown, a block 21 is provided at one end of the blade 2 near the cover 1. The block 21 is embedded in the embedding groove 14, and the blocks 21 abut against each other. A positioning post 211 protrudes from the block 21. A positioning cylinder 15 is provided in the embedding groove 14 corresponding to the positioning post 211. The positioning post 211 can be embedded in the positioning cylinder 15 and abut against the inner wall of the positioning cylinder 15. Each block 21 is provided with two positioning posts 211, and two positioning holes are provided corresponding to the positioning posts 211. The distance between the two positioning posts 211 on each block 21 is the same. By adopting the above technical solution, in specific implementation, in this embodiment, a total of five blades 2 are provided. The blocks 21 of each blade 2 abut against each other, completely sealing the embedding groove 14, while the upper and lower sides of the block 21 abut against the cover 1.

[0033] like Figure 2 and Figure 3As shown, the upper cover 11 has a protruding mating post 16 facing the lower cover 12, and the lower cover 12 has a mating hole 17 corresponding to the mating post 16. The lower cover 12 also has a protruding mating post 16 facing the upper cover 11, and the upper cover 11 has a mating hole 17 corresponding to the mating post 16. The mating post 16 can be embedded in the corresponding mating hole 17. In specific implementation, the upper cover 11 and the lower cover 12 can be accurately positioned through the mating post 16 and the mating hole 17, which can also improve the stability of the cover body 1 after installation.

[0034] like Figure 1 and Figure 2 As shown, both the upper cover 11 and the lower cover 12 have multiple threaded posts 18, which are arranged correspondingly to each other. Each threaded post 18 has a threaded hole 181 that passes through it. The cover body 1 also has multiple reinforcing ribs 19, which are positioned between the threaded posts 18 and the linkage post 13. One end of the reinforcing rib 19 is fixedly connected to the threaded post 18, and the other end is fixedly connected to the linkage post 13. In practice, the reinforcing ribs 19 improve the strength of the cover body 1, thereby increasing its stability. Disassembly and assembly of the upper cover 11 and the lower cover 12 can be performed simply by removing or installing the bolts.

[0035] like Figure 1 and Figure 2 As shown, the blade 2 is provided with a mesh rib 22, which is arranged along the length of the blade 2. In practice, the mesh rib 22 can enhance the strength of the blade 2, thereby further improving the service life of the blade 2.

[0036] Working principle: The upper cover 11 and the lower cover 12 are connected by bolts, which allows for quick disassembly of the cover 1 and easier assembly and disassembly of the blade 2, further improving the convenience of blade 2 assembly and disassembly.

[0037] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
