[0044] Working principle: The fan body 10 is fixed above the ground through a support structure. The motor 35 is arranged on one side of the fan body 10, and its output shaft is connected to the fan impeller 15 through a coupling. When the motor 35 is started, it drives the fan impeller 15 to rotate, thereby sucking air at the air inlet 11 and delivering the air flow through the air outlet 16. The fan is supported by a support base 36 and a moving bracket 37. The bottom of the moving bracket is equipped with universal wheels, enabling the entire fan to be easily moved to the required position. A clamping ring groove 14 is provided inside the air inlet 11 for installing the second dust-proof net plate 33. A rubber ring 34 is attached to the outer wall of the dust-proof net plate to ensure tight fit with the clamping ring groove 14 and prevent dust from entering. The air inlet is further sealed by the baffle 17, the second fixing ring plate 18 and the plug 19 thereon, enhancing the dust-proof effect. The inside of the air outlet 16 is designed with a first clamping groove 21 and a first clamping rod groove 22, which cooperate with the first fixing plate 27, the second fixing plate 28 and the clamping rod 29 to achieve quick disassembly and installation. The first dust-proof net plate 32 is installed at the bottom of the first fixing plate 27 to perform secondary filtration on the discharged air flow. By rotating the adjusting plate 30 and the second threaded sleeve 31 and combining with the first threaded groove 23, the position of the first fixing plate 27 inside the air outlet 16 can be flexibly adjusted and fixed, facilitating the maintenance and replacement of the dust-proof net plate. The air flow generated by the motor driving the fan impeller to rotate is preliminarily filtered by the second dust-proof net plate at the air inlet and then enters the fan interior, and is further filtered by the first dust-proof net plate at the air outlet, and finally output through an external air delivery pipe (connected to the first threaded sleeve 26). The ventilation box 25, the holes thereon and the first threaded sleeve 26 not only facilitate the connection of the external air delivery pipe, but also play a role in guiding the air flow direction and reducing the air flow resistance. The quick-disassembly design of the dust-proof net plate and the baffle enables users to easily take out and clean the dust-proof net plate or replace damaged components without disassembling the entire fan, improving the maintenance efficiency and convenience.

[0045] It can be understood that the present utility model is described through some embodiments.
