Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to a cooling fan that is easy to clean. Background Art

[0002] The existing fans have a small air volume during the air delivery process and low working efficiency. In addition, the existing fans have a complex structure and are not easy to clean inside the fans. At the same time, if the fans are cleaned without removing the motor, the motor may be damaged due to the inability to see the parts clearly. If a thorough cleaning is required, the housing must be disassembled and the parts must be removed. The operation process is complicated, time-consuming and labor-intensive, and the parts may be easily damaged. The process of repairing the motor is also very troublesome. Most people do not perform dust removal and other maintenance on the fans due to the troublesome maintenance process, which shortens the service life of the fans.

[0003] A cooling fan which is easy to clean is now provided and can automatically clean the fan at a fixed time. Utility Model Content

[0044] The cleaning motor 20 is fixedly connected to the top wall of the transverse plate 19, and the mounting plate 21 is fixedly connected to the output shaft of the cleaning motor 20. The output shaft of the cleaning motor 20 is vertically downward and is arranged perpendicular to the extension direction of the output shaft of the fan motor 13. The cleaning roller 22 is fixedly connected to the mounting plate 21 by bolts, and the cleaning roller 22 includes: two fixed plates 25, a connecting column 26 and a plurality of columnar soft hairs 27; the two ends of the connecting column 26 are respectively fixedly connected to the two fixed plates 25, and the plurality of columnar soft hairs 27 are respectively fixedly connected to the connecting column 26 at equal intervals along the axial direction and the circumferential direction of the connecting column 26, and the length of the columnar soft hairs 27 is greater than the diameter of the fixed plate 25. The controller 14 is fixedly connected to the fan motor 13 and electrically connected to the fan motor 13.

[0045] Working or installation process:

[0046] In the first step, the fan motor 13 is started, and the output shaft of the fan motor 13 drives the fan blades 15 to rotate and stir the airflow for ventilation and other work; when the fan motor 13 is started, a signal for starting the fan motor 13 is transmitted to the controller 14, and the controller 14 controls the timer 23 to start, and the timer 23 starts timing;

[0047] In the second step, the timer 23 starts timing and when the timer 23 records that the duration of the fan motor 13 starting reaches the set value, the timer 23 transmits a signal that the fan motor 13 has started for a certain duration to the controller 14, and the controller 14 controls the traverse motor 16 and the cleaning motor 20 to start. The traverse motor 16 starts, and the output shaft of the traverse motor 16 drives the threaded shaft 17 to rotate. The threaded shaft 17 is threadedly connected to the traverse plate 19 and drives the traverse plate 19 to move. The traverse plate 19 moves to the side close to the fan blade 15, so that the columnar soft hairs 27 contact the fan blade 15, and the traverse motor 16 stops starting; the controller 14 transmits a signal to start the cleaning motor 20 to the timer 23, and the timer 23 records the time when the cleaning motor 20 starts;

[0048] In the third step, the cleaning motor 20 is started, and the output shaft of the cleaning motor 20 drives the mounting plate 21 to rotate, and the mounting plate 21 synchronously drives the fixing plate 25, the connecting column 26 and the columnar soft hair 27 to rotate, and the columnar soft hair 27 rotates and cleans the rotating fan blades 15. When the cleaning motor 20 drives the columnar soft hair 27 to clean and the start time of the cleaning motor 20 reaches the set value, the timer 23 transmits a signal that the rotation time of the cleaning motor 20 reaches the set value to the controller 14, and the controller 14 controls the cleaning motor 20 to stop running again, and the columnar soft hair 27 stops rotating;

[0049] In the fourth step, after the controller 14 controls the cleaning motor 20 to stop, the controller 14 controls the traverse motor 16 to start in the reverse direction, and the traverse motor 16 starts in the reverse direction and drives the traverse plate 19 to move to the side away from the fan blade 15, so that the columnar soft hair 27 is out of contact with the fan blade 15;

[0050] In the fifth step, after the transverse movement motor 16 is started in reverse, the timer 23 will reset the time of the fan motor 13 starting to zero and start again to record the running time of the fan motor 13. When the running time of the fan motor 13 recorded by the timer 23 reaches the set value again, the above-mentioned first, second, third and fourth steps are repeated.

[0051] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used.
