[0027] The surface of the connecting member 5 is screwed with a housing 2 , the micro motor body 6 is installed in the housing 2 , and a handle 3 is welded on the lower surface of the housing 2 .

[0028] It should be noted that: by designing the tip of the cleaning strip 7 to be round and the top of the push plate 14 to be arcuate, the rotation of the cleaning strip 7 will not affect the sliding of the push plate 14.

[0029] When the user uses the fan for heat dissipation;

[0030] First, the micro motor is started to drive the micro motor shaft 4 to rotate, and the rotation of the micro motor shaft 4 drives the fan blades 1 to rotate and blow air.

[0031] At the same time, the rotation of the micromotor shaft 4 drives the shielding ring 15 to rotate, and the rotation of the shielding ring 15 drives the cleaning bar 7 to move to clean the dust between the hole 8 and the gap between the micromotor shaft 4. After the cleaning bar 7 drives the dust to the position of the ash storage tank 9, the dust falls freely into the ash storage tank 9 and is temporarily stored.

[0032] When it is necessary to clean the dust temporarily stored in the ash storage tank 9;

[0033] First, the connecting plate 11 is pulled by external force to move, and the movement of the connecting plate 11 drives the spring 12 to stretch. The movement of the connecting plate 11 drives the connecting rod 10 to move, and the movement of the connecting rod 10 drives the push plate 14 to move and push the dust inside the ash storage tank 9 to move out of the ash storage tank 9, thereby achieving the effect of cleaning the inside of the ash storage tank 9.

[0034] Subsequently, the connecting plate 11 is loosened, the spring 12 is reset to drive the connecting plate 11 to move, the movement of the connecting plate 11 drives the connecting rod 10 to move, and the movement of the connecting rod 10 drives the push plate 14 to move to the bottom of the ash storage tank 9.

[0035] By setting up a protection component and an ash storage component, the cleaning strip 7 in the protection component can drive the dust between the micro motor shaft 4 and the hole 8 to move to the ash storage tank 9 in the ash storage component for temporary storage. At the same time, the shielding ring 15 can block the gap between the hole 8 and the micro motor shaft 4 to prevent dust from entering the interior of the micro motor body 6 through the gap between the hole 8 and the micro motor shaft 4 and causing damage to the micro motor, that is, protecting the micro motor from damage caused by external dust.

[0036] By setting a connecting plate 11 in the ash storage component, the connecting plate 11 can be pulled to drive the push plate 14 to move. The movement of the push plate 14 can drive the dust temporarily stored in the ash storage tank 9 to move out of the ash storage tank 9, so as to achieve the effect of cleaning the ash storage tank 9. In cooperation with the protective component, the dust between the hole 8 and the gap between the micro motor shaft 4 can be cleaned away from the micro motor.

[0037] Working principle:

[0038] When the user uses the fan for heat dissipation;

[0039] First, the micro motor is started to drive the micro motor shaft 4 to rotate, and the rotation of the micro motor shaft 4 drives the fan blades 1 to rotate and blow air.

[0040] At the same time, the micromotor shaft 4 drives the shielding ring 15 to rotate, and the shielding ring 15 drives the cleaning bar 7 to move to clean the dust between the hole 8 and the gap between the micromotor shaft 4. After the cleaning bar 7 drives the dust to move to the position of the dust storage tank 9, the dust falls freely.

[0041] When it is necessary to clean the dust temporarily stored in the ash storage tank 9;

[0042] First, the connecting plate 11 is pulled by an external force to move, the connecting plate 11 drives the spring 12 to stretch, the connecting plate 11 drives the connecting rod 10 to move, and the connecting rod 10 drives the push plate 14 to move to push the dust inside the ash storage tank 9 to move.

[0043] Subsequently, the connecting plate 11 is loosened, the spring 12 is reset to drive the connecting plate 11 to move, the connecting plate 11 drives the connecting rod 10 to move, and the connecting rod 10 drives the push plate 14 to move to the bottom of the ash storage tank 9.
