[0039] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0040] Please see Figure 1-5 A painting workshop exhaust fan includes a fan body 100 and a disassembly / assembly component 200. The fan body 100 includes an exhaust pipe 110, and an exhaust assembly 120 is provided on the inner side of the exhaust pipe 110. The disassembly / assembly component 200 is provided at both ends of the exhaust pipe 110. The disassembly / assembly component 200 includes a protective disassembly / assembly component 210 provided at one end of the exhaust pipe 110, and a louver disassembly / assembly component 220 provided at the other end of the exhaust pipe 110. Both the louver disassembly / assembly component 220 and the protective disassembly / assembly component 210 are connected to the exhaust pipe 110.

[0041] The protective disassembly and assembly component 210 facilitates the disassembly, cleaning, or replacement of the filter screen, and the louver disassembly and assembly component 220 facilitates the disassembly, cleaning, or replacement of the louvers, thereby effectively preventing dust accumulation on the filter screen and louvers and improving practicality.

[0042] The protective disassembly assembly 210 includes a mounting ring 211 movably connected to one end of the exhaust pipe 110. One end of the exhaust pipe 110 is threaded with multiple mounting pins 212, and all mounting pins 212 extend into the interior of the mounting ring 211. The protective disassembly assembly 210 also includes a slot 213 formed on the surface of the mounting ring 211. A disassembly ring 215 is movably engaged inside the slot 213. A protective filter screen 216 is provided on the inner side of the disassembly ring 215. The protective disassembly assembly 210 also includes two slots 214 formed on the mounting ring 211. Inserts 217 are movably inserted into the interior of each slot 214, and both inserts 217 are fixedly connected to the surface of the disassembly ring 215. Four fixing pins 218 are threadedly connected to one side of the mounting ring 211. Two fixing pins 218 extend into the interior of the two inserts 217, and the other two fixing pins 218 extend into the interior of the disassembly ring 215.

[0043] By movably engaging the disassembly ring 215 into the slot 213 and movably engaging the insert block 217 into the slot 214, and then threading four fixing pins 218 to the mounting ring 211 and extending into the disassembly ring 215 and the two insert blocks 217 respectively, the disassembly ring 215 and the insert blocks 217 can be fixed, thereby completing the installation and fixing of the protective filter screen 216.

[0044] The louver assembly 220 includes a first ring 221 movably connected to the other end of the exhaust pipe 110. The other end of the exhaust pipe 110 is threaded with a plurality of positioning pins 222, and the plurality of positioning pins 222 extend into the interior of the first ring 221. The louver assembly 220 also includes a louver body 223 fixedly connected to one end of the first ring 221. One end of the louver body 223 is fixedly connected with a second ring 224. The exhaust assembly 120 includes four mounting pieces 121 fixedly connected to the inside of the exhaust pipe 110. The four mounting pieces 121 are fixedly connected with mounting sleeves 122. The inside of the mounting sleeves 122 is fixedly connected with a drive motor 123, and the output end of the drive motor 123 extends to the outside of the mounting sleeves 122. The exhaust assembly 120 also includes a mounting plate 124 fixedly connected to the output end of the drive motor 123. One side of the mounting plate 124 is fixedly connected with a fan blade 125.

[0045] By attaching the first ring 221 to the other end of the exhaust pipe 110, and then threading the positioning pin 222 into the inside of the first ring 221 and extending into the inside of the first ring 221, the first ring 221 can be installed and fixed, thereby realizing the installation and fixing of the louver body 223. By starting the drive motor 123, the drive motor 123 will drive the mounting plate 124 to drive the fan blade 125 to rotate, thereby enabling the exhaust work.

[0046] The implementation principle of this application embodiment is as follows: When it is necessary to disassemble, clean, or replace the protective filter screen 216 and the louver body 223, firstly, the fixing pin 218 can be rotated to remove the disassembly ring 215, the insert block 217, and the mounting ring 211, thereby releasing the fixing of the disassembly ring 215 and the insert block 217. Then, the disassembly ring 215 is lifted upwards, causing it to retract from the slot 213, and the two insert blocks 217 are also retracted from the two slots 214, thereby allowing the disassembly ring 215 to be disassembled. This allows for the disassembly and assembly of the protective filter 216, facilitating its cleaning or replacement. By rotating the positioning pin 222, the positioning pin 222 can be removed from the first ring 221, thereby engaging the fixing of the first ring 221. This enables the disassembly of the louver body 223, facilitating its cleaning or replacement. This allows the exhaust fan to disassemble, clean, or replace both the protective filter 216 and the louver body 223, improving its practicality.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
