[0024] As Figures 1-8 shown, a fan bracket with adjustable air outlet angle of the present invention includes a frame 2 and a fan body 1 provided on the frame 2. The fan body 1 includes a housing 3, a first motor 4 and a fan blade 5. The housing 3 is provided on the frame 2. An installation member 6 is provided inside the housing 3. The first motor 4 is provided on the installation member 6. The fan blade 5 is provided on the output shaft of the first motor 4. A rotating shaft 7 is provided on the housing 3. The housing 3 is rotatably provided on the frame 2 through the rotating shaft 7. An angle adjustment component for driving the rotating shaft 7 to rotate is provided on the frame 2. A dust-proof net 11 is detachably provided at the air inlet of the housing 3. A protection net 12 is detachably provided at the air outlet of the housing 3; the angle adjustment component includes a second motor 8, a first gear 9 and a second gear 10. The second motor 8 is provided on the frame 2. The first gear 9 is provided on the output shaft of the second motor 8. The second gear 10 is sleeved on the rotating shaft 7 and meshes with the first gear 9; the protection net 12 is detachably provided on the housing 3 through bolts 24.

[0025] The housing 3 is provided with a quick disassembly and assembly component 13. The dust-proof net 11 is detachably arranged on the housing 3 through the quick disassembly and assembly component 13. The quick disassembly and assembly component 13 includes a mounting frame 14 arranged at the air inlet of the housing 3, a pressing rod 15 slidably arranged on the mounting frame 14, a spring 16 sleeved on the pressing rod 15, and a fixing unit arranged on the pressing rod 15. A connecting plate is arranged on the pressing rod 15. The two ends of the spring 16 are respectively arranged on the mounting frame 14 and the connecting plate. The fixing unit includes a connecting rod 17 and a fixing block 18. The connecting rod 17 is hinged on the connecting plate, and the fixing block 18 is hinged on the connecting rod 17. A sliding groove is arranged on the mounting frame 14, and the fixing block 18 is engaged and slidably arranged in the sliding groove. An insertion block 20 is arranged on the dust-proof net 11, and the insertion block 20 can be inserted into the sliding groove. A round hole is arranged on the dust-proof net 11, and the dust-proof net 11 is slidably sleeved on the pressing rod 15 through the round hole. A fixing hole 21 is arranged on the insertion block 20, and a fixing head 19 is arranged on the fixing block 18. The fixing head 19 is slidably arranged in the fixing hole 21. There are several groups of fixing units, and several groups of fixing units are distributed in a circular array.

[0026] A base 22 is arranged at the bottom of the frame 2, and a self-locking universal wheel 23 for moving is arranged on the base 22.

[0027] During specific use, the self-locking universal wheel 23 facilitates the movement and locking and fixing of the fan body 1. The air outlet angle of the fan body 1 can be adjusted through the angle adjustment component. The second motor 8 can drive the first gear 9 to rotate, the first gear 9 drives the second gear 10 to rotate, and the second gear 10 drives the rotating shaft 7 to rotate, thereby driving the housing 3 to rotate, and thus the air outlet angle of the fan body 1 can be adjusted. The first motor 4 can drive the fan blade 5 to rotate and blow air. When the air flow enters the housing 3 from the side provided with the dust-proof net 11, the dust and impurities in the air flow can be filtered through the dust-proof net 11, avoiding the dust and impurities from adhering to the fan blade 5.

[0028] When the dust-proof net 11 needs to be disassembled and cleaned, only need to press the pressing rod 15, so that the pressing rod 15 drives the connecting rod 17 to rotate, making the spring 16 be stretched. The connecting rod 17 drives the fixing block 18 to move away from the insertion block 20, so that the fixing head 19 moves out of the fixing hole 21. At this time, the dust-proof net 11 can be removed. After the cleaning is completed, the dust-proof net 11 is sleeved on the pressing rod 15 through the round hole, then press the pressing rod 15, insert the insertion block 20 into the sliding groove at the corresponding position, and then release the pressing rod 15. Under the action of the spring 16, the fixing block 18 approaches the insertion block 20, and the fixing head 19 is inserted into the fixing hole 21, and thus the installation and fixing of the dust-proof net 11 can be realized, and the operation is simpler and more convenient.

[0029] In summary, the present solution is provided with an angle adjustment component, which facilitates the adjustment of the inclination angle of the housing 3 through the angle adjustment component, so as to realize the adjustment of the air outlet angle of the fan body 1, with higher flexibility; the present solution is provided with a dust-proof net 11, which can play a role in blocking dust through the dust-proof net 11, preventing external dust and impurities from entering the frame 2 along with the air flow and adhering to the fan blades 5, and the dust-proof net 11 can be conveniently disassembled and cleaned through the quick disassembly and assembly component 13; the present solution is provided with a protective net 12, which can form a safety barrier between the fan blades 5 and the outside world to prevent the fan blades 5 from causing harm to others.
