A first fixing plate 10 for fixedly connecting each grille piece 7 is arranged at the center of the fan grille 6.

[0032] Since it is composed of a plurality of grille pieces 7 connected by convex connecting ribs 8 and concave connecting ribs 9, and fixed by the first fixing plate 10, and a ring-shaped body 5 composed of a plurality of arc-shaped frames 4, it is not only convenient for disassembly and assembly, facilitating the separate replacement of damaged grille pieces 7 and arc-shaped frames 4, but also has a stable connection structure, effectively ensuring the overall strength and protection performance of the fan grille 6.

[0033] A fixed bracket 11 is arranged inside the annular frame body 5, and at least one fixed bracket 11 is provided on each arc-shaped frame 4. The fixed bracket 11 extends along the center inside the annular frame body 5, and the fan assembly 3 is fixedly arranged at the center of the annular frame body 5 through the fixed bracket 11.

[0034] The fixed bracket 11 arranged inside the annular frame body 5 provides stable support for the fan assembly 3, ensuring the stability of the fan during operation. At least one fixed bracket 11 is provided on each arc-shaped frame 4. This distribution method makes the fixation of the fan assembly 3 at the center of the annular frame body 5 more firm, reducing failures caused by vibration.

[0035] The fan assembly 3 includes a fan motor 12, a plurality of fan blades 13, and a connecting piece 14 for fixing the fan blades 13. A motor shaft 121 extends from the fan motor 12. The connecting piece 14 is arranged on the motor shaft 121, and the fan blades 13 are detachably arranged on the motor shaft 121 through the connecting piece 14.

[0036] The fan blades 13 in the fan assembly 3 are detachably arranged on the motor shaft 121 through the connecting piece 14, which facilitates the separate disassembly, cleaning, and replacement of the fan blades 13. The spacer block 23 in the connecting piece 14 can ensure uniform spacing between the fan blades 13, improving the air outlet efficiency and stability of the fan.

[0037] A sliding base 15 is further provided at the lower end of the annular frame body. The sliding base 15 includes supports 16 arranged on the left and right sides at the lower end of the annular frame body, and a base bracket 17 for connecting the supports 16 on the left and right sides. Universal wheels 18 for sliding are arranged at the lower ends of the two supports 16.

[0038] By providing the sliding base 15 at the lower end of the annular frame body, especially the universal wheels 18 at the lower ends of the supports 16, the fan can be easily moved to meet the usage requirements at different positions, greatly improving the flexibility and convenience of the fan.

[0039] A handle 19 and a control box 20 are provided at the upper end of the annular frame body 5, and at least one handle 19 is provided.

[0040] By providing the handle 19 at the upper end of the annular frame body 5, it is convenient for users to pull the fan for position adjustment, and the control box 20 facilitates users to control the operating state of the fan, making the operation more convenient.

[0041] The connecting piece 14 includes a second fixing plate 21 and a rotating plate 22 for fixedly connecting each fan blade 13. A spacer block 23 for spacing the fan blades 13 is arranged on the rotating plate 22. The fan blades 13 are annularly arranged on the rotating plate 22 through the spacer block 23 and are fixedly connected to the rotating plate 22 through the second fixing plate 21.

[0042] By setting the second fixed disk 21 and the rotating disk 22 in the connecting member 14, the fan blade 13 can be firmly fixed. The setting of the spacer block 23 makes the installation of the fan blade 13 more regular, which helps to optimize the air outlet effect and running stability of the fan.

[0043] At least one base bracket 17 is provided.

[0044] By providing the base bracket 17, the structural strength of the sliding base 15 is enhanced, ensuring the stability of the fan during movement and use, and avoiding tilting or toppling.

[0045] As Figures 1 to 5 shown, during normal operation, the fan motor 12 starts, driving the motor shaft 121 to rotate. Through the connecting member 14, the fan blade 13 rotates accordingly, generating an air flow. The fan grille 6 of the fan housing 2 is connected by a plurality of grille pieces 7 through convex and concave connecting ribs 9 and fixed by the first fixed disk 10, which is convenient for disassembly and assembly and facilitates the replacement of damaged grille pieces 7. The fixed bracket 11 in the annular frame 5 makes the installation of the fan assembly 3 stable. The fan blade 13 of the fan assembly 3 is detachably mounted on the motor shaft 121 through the connecting member 14, which is beneficial for cleaning and maintenance. The sliding base 15 at the lower end of the annular frame, through the combination of the support 16, the base bracket 17 and the universal wheel 18, makes the fan move conveniently and flexibly. The handle 19 and the control box 20 at the upper end of the annular frame 5 are convenient for users to operate and carry. The second fixed disk 21, the rotating disk 22 and the spacer block 23 in the connecting member 14 can stably fix the fan blade 13, ensuring the air outlet effect. The base bracket 17 enhances the stability of the sliding base 15.

[0046] In this Embodiment 2,

[0047] As Figures 1 to 5 shown, during assembly, first fix the fan motor 12 at the central position of the annular frame 5 through the fixed bracket 11 in the annular frame 5. Then, install the fan blade 13 on the motor shaft 121 through the connecting member 14. The rotating disk 22 and the spacer block 23 in the connecting member 14 can ensure that the fan blades 13 are evenly distributed and properly spaced, and then fix them with the second fixed disk 21. The assembly of the fan grille 6 is also very convenient. Each grille piece 7 is arranged radially outward from the center of the circle, connected to each other through the convex connecting rib 8 and the concave connecting rib 9, and finally fixed by the first fixed disk 10 at the center of the circle. Connect the support 16 of the sliding base 15 and the base bracket 17, and install the universal wheel 18 at the lower end of the support 16. Install the handle 19 and the control box 20 at the corresponding positions of the annular frame 5.

[0048] In this Embodiment 3,

[0049] As Figures 1 to 5As shown, when the fan malfunctions and needs to be repaired, due to its unique structural design, it is possible to quickly identify the damaged components. If a certain fan blade 13 is damaged, simply loosen the second fixing plate 21 on the connecting member 14, and the damaged fan blade 13 can be removed separately for replacement. If a certain wind deflector blade 7 of the fan grille 6 is damaged, the fixing of the first fixing plate 10 can be released, and the damaged wind deflector blade 7 can be separated from the convex connecting rib 8 and the concave connecting rib 9 for replacement. This repair method of only replacing the damaged components not only saves the repair cost but also greatly improves the repair efficiency. This fan that is easy to disassemble and assemble has many remarkable advantages.
