Detailed Implementation

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a fan with a dustproof component, including a fan housing 1, a fan mounting bracket 2 fixedly installed inside the fan housing 1, a fan 3 arranged on the lower surface of the fan mounting bracket 2, a disassembly and fixing device 4 fixedly installed on the outer side of the fan housing 1, a dustproof cover plate 5 arranged on the upper surface of the fan housing 1, a dustproof net 6 fixedly installed on the inner side of the dustproof cover plate 5, and a connecting column 7 fixedly installed on the lower surface of the dustproof cover plate 5.

[0022] The disassembly and fixing device 4 includes a U-shaped fixing plate 401 fixedly installed on the outer side of the fan housing 1. The U-shaped fixing plate 401 has a sliding rectangular sliding frame 402 inside. A pull handle 403 is fixedly installed on the lower surface of the rectangular sliding frame 402. A positioning rod 404 inserted into the U-shaped fixing plate 401 passes through the U-shaped fixing plate 401. A pull bracket 405 is fixedly installed on the top of the rectangular sliding frame 402. A rotatable pull rod 406 is provided on the top of the pull bracket 405. A rotatable movable bracket 407 is provided on the outer side of the pull rod 406. A positioning insert 408 is fixedly installed on the outer side of the movable bracket 407. A positioning block 409 connected to the outer side of the dust cover 5 is provided on the outer surface of the positioning insert 408.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, the four corners of the upper surface of the fan housing 1 are provided with docking grooves. The size of the docking grooves is adapted to the size of the docking column 7. The docking grooves at the four corners of the upper surface of the fan housing 1 and the docking column 7 cooperate with each other, which improves the convenience of installation.

[0024] Specifically, such as Figure 3 As shown, the outer side of the rectangular sliding frame 402 has multiple sets of positioning through holes. The size of the positioning through holes is adapted to the size of the positioning rod 404. The positioning through holes on the outer side of the rectangular sliding frame 402 and the positioning rod 404 cooperate with each other to improve the positioning stability. The bottom of the positioning block 409 has a positioning round hole. The size of the positioning round hole is adapted to the size of the positioning insertion rod 408. The positioning round hole at the bottom of the positioning block 409 and the positioning insertion rod 408 cooperate with each other to facilitate more stable positioning. The outer surface of the pull handle 403 is provided with an anti-slip layer. The outer surface of the anti-slip layer is uniformly provided with friction anti-slip textures. The friction anti-slip textures on the outer surface of the pull handle 403 increase the friction and improve the anti-slip effect.

[0025] The working principle of this utility model is as follows:

[0026] S1. When it is necessary to disassemble and clean the dust cover 5 and dust net 6, control the pull handle 403 to move the rectangular sliding frame 402 downward, the rectangular sliding frame 402 to move the pull bracket 405, the pull bracket 405 to move the pull rod 406, the pull rod 406 to move the moving bracket 407, and the moving bracket 407 to pull the positioning rod 408 out inside the positioning block 409. Then the dust cover 5 and dust net 6 can be removed for cleaning.

[0027] S2. After cleaning, the dust cover 5 and dust net 6 need to be installed. The dust cover 5 and dust net 6 are connected to the column 7 and inserted into the inside of the fan box 1 to achieve quick installation.

[0028] S3. Then, control the pull handle 403 to move the rectangular sliding frame 402, the rectangular sliding frame 402 to move the pull bracket 405, the pull bracket 405 to move the pull rod 406, the pull rod 406 to move the moving bracket 407, and the moving bracket 407 to move the positioning rod 408 to insert into the dust cover 5 in the positioning block 409 for positioning.

[0029] In summary, this fan with dustproof components, by setting up a pull handle 403 and a rectangular sliding frame 402 to drive the pull bracket 405 and the pull rod 406, allows the moving bracket 407 and the positioning rod 408 to be inserted into the positioning block 409 to position the dustproof cover 5. This results in a better positioning effect for the dustproof cover 5, and while ensuring the positioning effect, it also makes it easier to disassemble the dustproof cover 5. This makes the disassembly of the dustproof net 6 simpler and more convenient, and helps people use it better.

[0030] The fan with dustproof components can be quickly installed by using a dustproof cover 5 and a dustproof net 6 to connect with a column 7 and insert them into the fan housing 1. This makes the installation of the dustproof cover 5 and the dustproof net 6 simpler and more convenient, and also makes it easier to replace the dustproof cover 5 and the dustproof net 6. This helps to better maintain the fan 3 and further improves its usability.
