Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a fan structure that is easy to assemble and disassemble. Background Technology

[0002] In modern living and industrial environments, fans have become indispensable equipment in homes, offices, and various factories due to their excellent ventilation and heat dissipation performance. As people's requirements for quality of life and working environment continue to improve, regular cleaning and maintenance of fans, especially the fan blade module, has become a key step in ensuring the fan's air delivery effect and extending its service life.

[0003] Currently, common fan blade modules on the market generally consist of a cover, a front mesh, and fan blades. However, the disassembly and cleaning process for these modules has significant drawbacks. Users must first remove the front mesh, then disassemble the fan blades housed within the cover, and finally unscrew the screws connecting the cover to the head unit to complete the cover's removal. This layered, step-by-step disassembly process is not only time-consuming and labor-intensive, but also inefficient due to the inability to disassemble the entire fan blade module at once, severely impacting the user experience. In today's pursuit of efficiency and convenience, the existing disassembly structure of fan blade modules is insufficient to meet market demands, and its technical solutions have significant room for improvement, requiring innovative designs to address the aforementioned issues.

[0005] A fan structure designed for this purpose that is easy to assemble and disassemble includes a base, a head module, and a fan blade module, wherein the head module is connected to the base;

[0006] The fan blade module includes a cover, a front mesh component, and fan blade elements. The front mesh component is connected to the cover, and the fan blade elements are disposed within the cover. The cover is provided with a forward-extending shaft component, and the fan blade elements are rotatably connected to the shaft component.

[0007] The shaft is hollow inside and has openings at both the front and rear ends;

[0008] The head module includes at least a motor, and the motor shaft of the motor passes through the shaft and is connected to the fan blade element in a transmission manner.

[0009] The cover is provided with a plurality of first magnetic components, and the head module is provided with a plurality of second magnetic components. The second magnetic components and the first magnetic components attract each other to connect the cover and the head module.

[0010] Preferably, the fan blade element is provided with a transmission insertion hole, and the motor shaft of the motor is inserted into the transmission insertion hole.

[0011] Preferably, a bearing is installed on the outer wall of the shaft, and a boss is provided on the shaft behind the bearing that abuts against the rear wall surface of the bearing. A limiting member is connected to the shaft behind the bearing, and the bearing is fixed between the limiting member and the boss. The fan blade element is connected to the bearing and rotates relative to the shaft.

[0012] Preferably, the head module further includes a mounting shell, the motor is fixedly disposed in the mounting shell, the second magnetic suction member is disposed on the front surface of the mounting shell, and the first magnetic suction member is disposed on the rear surface of the cover.

[0013] Preferably, the fan blade element is provided with a connecting ring that is inserted into the outer ring of the bearing, and the connecting ring is provided with a limiting rib that fits against the front surface of the bearing and a connecting buckle that hooks onto the rear surface of the bearing.

[0017] Compared with existing technologies, this utility model effectively solves the problem of complex disassembly of the fan blade module by using an innovative design that connects the cover and the head module with magnetic attraction. When the fan blade module needs to be cleaned and maintained, there is no need to remove the screws with tools. By simply overcoming the attraction of the first and second magnetic components, the cover, along with the front mesh and fan blade components, can be quickly removed from the head module, achieving one-time disassembly of the entire fan blade module. This greatly simplifies the operation process and significantly improves cleaning efficiency. During installation, the magnetic attraction enables precise positioning, allowing the cover and head module to automatically and quickly align and connect, making the operation simple, time-saving, and labor-saving.

The fan blade module 30 includes a cover 310, a front mesh 320, and fan blade elements 340. The front mesh 320 is connected to the cover 310. The fan blade elements 340 are disposed within the cover 310. The cover 310 is provided with a forward-extending shaft 330, and the fan blade elements 340 are rotatably connected to the shaft 330. The shaft component 330 is hollow inside and open at both ends. The head module 20 includes at least a motor 220, whose motor shaft 230 passes through the shaft component 330 and is connected to the fan blade element 340. The cover 310 is provided with a plurality of first magnetic attractors 410, and the head module 20 is provided with a plurality of second magnetic attractors 420. The second magnetic attractors 420 and the first magnetic attractors 410 attract each other to connect the cover 310 and the head module 20.
