A protective cover 3 is arranged on the side of the variable frequency exhaust fan body 2 away from the device outer frame 1, and the protective cover 3 protects the variable frequency exhaust fan body 2. Two symmetrically distributed fixing parts 4 are fixedly installed on the outer side of the protective cover 3;

[0027] A bearing 32 is fixedly provided in the middle of the protective cover 3, and a rotating shaft 33 is fixedly provided in the middle of the bearing 32. A mounting bracket 34 is movably installed at one end of the rotating shaft 33 away from the bearing 32. A cleaning brush 35 is fixedly installed on one side of the mounting bracket 34 close to the protective cover 3, and the cleaning brush 35 contacts the outer wall of the protective cover 3. A male drive shaft 23 is fixedly installed in the middle of the exhaust fan fan in the variable frequency exhaust fan body 2, and a card protrusion 331 is integrally formed at one end of the rotating shaft 33 away from the mounting bracket 34. The card protrusion 331 is movably connected to the middle part of the male drive shaft 23 to connect the rotating shaft 33 and the male drive shaft 23. When the variable frequency exhaust fan body 2 is in use, the exhaust fan fan rotates, driving the male drive shaft 23 to drive the rotating shaft 33 to rotate synchronously, thereby driving the mounting bracket 34 and the cleaning brush 35 to rotate. Since the cleaning brush 35 contacts the outer wall of the protective cover 3, the cleaning brush 35 cleans the outer wall of the protective cover 3 from dust to prevent dust accumulation and affect the overall ventilation effect of the fresh air dehumidification equipment.

[0028] A ventilation slot 101 corresponding to the variable frequency exhaust fan body 2 is provided on one side of the equipment outer frame 1. The variable frequency exhaust fan body 2 and the protective cover 3 are movably connected in the ventilation slot 101 to perform external installation of the variable frequency exhaust fan body 2 and the protective cover 3, which is convenient for subsequent disassembly and maintenance of the variable frequency exhaust fan body 2 and the protective cover 3 from the outside.

[0029] The fixing member 4 includes a fixing frame 41, which is fixedly installed on the outer side of the protective cover 3. A limiting groove 102 corresponding to the fixing frame 41 is provided on the inner side of the ventilation groove 101. The fixing frame 41 is movably connected in the limiting groove 102 to limit the frequency conversion exhaust fan body 2 and the protective cover 3. A sliding groove 401 is provided in the middle of the fixing frame 41. A chuck 42 is slidably connected in the middle of the sliding groove 401. A fixing column 43 is fixedly installed in the middle of one side of the chuck 42. One end of the fixing column 43 away from the chuck 42 extends out of the outer side of the fixing frame 41. A positioning groove 103 corresponding to the fixing column 43 is provided on the inner side of the limiting groove 102. The fixing column 43 is movably connected in the positioning groove 103 to fix the fixing column 43 and the equipment outer frame 1, thereby externally fixing the frequency conversion exhaust fan body 2 and the protective cover 3.

[0030] A spring 44 is provided on the side of the chuck 42 away from the fixed column 43, and a push block 45 is fixedly installed on the outer side of the chuck 42.

The push block 45 is slidably engaged in the card-through groove 402, and one end of the push block 45 away from the chuck 42 extends out of the outer side of the fixed frame 41.

[0031] A sealing plate 46 is fixedly installed in the middle of the push block 45, and the sealing plate 46 contacts the outer wall of the fixed frame 41; the size of the sealing plate 46 is larger than the size of the card-penetrating groove 402. By setting the sealing plate 46, the sealing plate 46 blocks the card-penetrating groove 402 to prevent external dust from entering the fixed frame 41 through the card-penetrating groove 402.

[0032] The top and bottom of the variable frequency exhaust fan body 2 are fixedly installed with fixing plates 21, and the protective cover 3 is movably clamped between the two fixing plates 21. A fixing screw 22 is threadedly installed on one side of the fixing plate 21 close to the protective cover 3. The fixing screw 22 is threadedly installed on the protective cover 3 to fix the variable frequency exhaust fan body 2 and the protective cover 3 with screws, which facilitates the disassembly of the variable frequency exhaust fan body 2 and the protective cover 3.

[0033] A protective ring 31 is fixedly mounted on one side of the protective cover 3 away from the variable frequency exhaust fan body 2 . A mounting frame 34 and a cleaning brush 35 are located in the protective ring 31 . The protective ring 31 protects the mounting frame 34 and the cleaning brush 35 .

[0034] Two limiting screw rings 341 are threadedly installed on one end of the rotating shaft 33 away from the bearing 32 , and the mounting frame 34 is located between the two limiting screw rings 341 . The mounting frame 34 is limited and fixed by providing the two limiting screw rings 341 .

[0035] Working principle: When in use, manually press the push blocks 45 on both sides towards each other, drive the chuck 42 and the fixed column 43 to move towards each other, the extrusion spring 44 contracts, and the fixed column 43 is stored in the fixed frame 41;

[0036] Subsequently, the variable frequency exhaust fan body 2 and the protective cover 3 are movably connected in the ventilation slot 101, and the fixed frame 41 is movably connected in the limit slot 102. At this time, the fixed column 43 corresponds to the positioning slot 103. Subsequently, the push blocks 45 on both sides are loosened, the spring 44 is reset, the driving chuck 42 and the fixed column 43 move in reverse, and the fixed column 43 is movably connected in the positioning slot 103 to fix the fixed column 43 and the equipment outer frame 1, thereby externally fixing the variable frequency exhaust fan body 2 and the protective cover 3. Compared with the traditional internal installation and fixation, it is convenient to externally disassemble and repair the variable frequency exhaust fan body 2 and the protective cover 3, which is simple and convenient.

[0037] When the fresh air dehumidification equipment is used, by setting the variable frequency exhaust fan body 2, and using the compressor, condenser and evaporator together, the exhaust air volume and fresh air volume can be adjusted according to actual needs, and ventilation control and dehumidification can be performed accurately;

[0038] When the variable frequency exhaust fan body 2 is in use, the exhaust fan fan rotates, driving the public drive shaft 23 to drive the rotating shaft 33 to rotate synchronously, and then driving the mounting frame 34 and the cleaning brush 35 to rotate. Since the cleaning brush 35 is in contact with the outer wall of the protective cover 3, the cleaning brush 35 cleans the dust on the outer wall of the protective cover 3 to prevent dust accumulation and affect the overall ventilation effect of the fresh air dehumidification equipment.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
