[0030] Reference Figure 1-8 This utility model discloses an energy-saving axial flow fan, comprising: a base plate 1, a rotating groove 2 fixedly connected to the top of the base plate 1, a servo motor 3 fixedly connected inside the rotating groove 2, a turntable 4 fixedly connected to the output end of the servo motor 3 via a coupling, a sliding groove on the top of the turntable 4, a sliding rod 5 fixedly connected to the inner wall of the sliding groove, a slider 9 slidably connected to the outer wall of the sliding rod 5, a second cylinder 7 fixedly connected to the top of the slider 9, a first cylinder 6 fixedly connected to the top of the turntable 4, a bracket 12 rotatably connected to the output ends of the first cylinder 6 and the second cylinder 7, and a fan body 13 fixedly connected to the top of the bracket 12. By adjusting the height difference between the output ends of the first cylinder 6 and the second cylinder 7, the tilt angle of the fan body 13 can be adjusted. The servo motor 3 can drive the rotation of the turntable 4, thereby adjusting the direction of the fan body 13.

[0031] A dustproof net 16 is movably connected to one side of the fan body 13. Mounting blocks 17 are fixedly connected to both sides of the dustproof net 16. Movable holes 18 are provided at the top and bottom of the mounting blocks 17. A positioning spring 19 is fixedly connected inside the movable hole 18. A positioning block 20 is fixedly connected to the other end of the positioning spring 19. A lever 22 is fixedly connected to the outer wall of the positioning block 20. The positioning block 20 is connected to the positioning hole 15 on the mounting groove 14 by the elastic force of the positioning spring 19, which facilitates the connection between the mounting block 17 and the mounting groove 14, and thus facilitates the installation of the dustproof net 16. When disassembling, moving the lever 22 can drive the positioning block 20 to disconnect from the positioning hole 15, which facilitates the disassembly of the dustproof net 16.

[0032] The shape and size of the turntable 4 are matched with the shape and size of the rotating groove 2. The turntable 4 is rotatably connected to the inner wall of the rotating groove 2 under the action of the servo motor 3. The servo motor 3 can drive the turntable 4 to rotate, which facilitates the rotation of the fan body 13 on the top of the turntable 4.

[0033] A limiting hole 10 is provided on the side of the slider 9. The slider 9 is slidably connected to the outer wall of the slide rod 5 through the limiting hole 10, which facilitates the limiting of the slider 9.

[0034] Both the output ends of the first cylinder 6 and the second cylinder 7 are provided with through holes 8. A hinge 11 is fixedly installed at the bottom of the bracket 12. The output ends of the first cylinder 6 and the second cylinder 7 are rotatably connected to the bracket 12 through the through holes 8 and the hinge 11. One end of the bracket 12 and the fan body 13 will tilt towards the lower end of the output ends of the first cylinder 6 and the second cylinder 7, thereby facilitating the adjustment of the tilt angle of the fan body 13.

[0035] The fan body 13 has mounting slots 14 on both sides. The shape and size of the mounting slots 14 match the shape and size of the mounting block 17. The mounting block 17 is movably connected to the mounting slots 14, which facilitates the installation of the dustproof net 16.

[0036] The diameter of the positioning block 20 is smaller than the diameter of the movable hole 18. The positioning block 20 is slidably connected to the inner wall of the movable hole 18. Moving the lever 22 can cause the positioning block 20 to retract into the movable hole 18, thereby facilitating the subsequent installation and removal of the dustproof net 16.

[0037] The shape and size of the positioning block 20 match the shape and size of the positioning hole 15. The positioning block 20 is movably connected to the positioning hole 15 under the action of the positioning spring 19. The positioning block 20 is connected to the positioning hole 15 by the elastic force of the positioning spring 19, which facilitates the connection between the mounting block 17 and the mounting groove 14, and thus facilitates the installation of the dustproof net 16.

[0038] The mounting block 17 has a groove 21 on its side, which is connected to the movable hole 18. The lever 22 is slidably connected to the inner wall of the groove 21. By moving the lever 22, the positioning block 20 can be moved into the movable hole 18, which facilitates the installation and removal of the dustproof net 16.

[0039] Working principle: When it is necessary to adjust the tilt angle of the fan body 13, for example, when the fan body 13 needs to tilt towards one end of the first cylinder 6, the height of the output end of the first cylinder 6 needs to be lower than the height of the second cylinder 7, thereby driving the slider 9 to move towards the end closer to the first cylinder 6. At the same time, one end of the air outlet of the fan body 13 will tilt towards one end of the first cylinder 6, so that the tilt angle of the fan body 13 can be adjusted. Furthermore, the servo motor 3 can drive the turntable 4 to rotate, thereby driving the fan body 13 to rotate, which facilitates the adjustment of the direction of the fan body 13.

[0040] When the dustproof net 16 needs to be cleaned, move the lever 22 in the direction of compressing the positioning spring 19. This will cause the positioning block 20 to retract into the movable hole 18, thereby disconnecting the connection between the positioning block 20 and the positioning hole 15. The dustproof net 16 can then be removed. After cleaning, when installing, move the lever 22 again to retract the positioning block 20 into the movable hole 18. Insert the mounting blocks 17 on both sides of the dustproof net 16 into the corresponding mounting slots 14. When the position of the positioning block 20 corresponds to the positioning hole 15, release the lever 22. The positioning block 20 will then connect with the positioning hole 15 under the elastic force of the positioning spring 19, thus completing the installation of the dustproof net 16.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
