[0002] The vacuum cleaner uses the impeller of the dust collecting fan to be driven at high speed by the motor. The blades in the impeller continuously work on the air, so that the air in the impeller gains energy and is discharged from the dust collecting fan at a very high speed. At the same time, the air in the dust collecting part at the front end of the dust collecting fan continuously replenishes the air in the impeller, resulting in an instantaneous vacuum in the dust collecting part, that is, a relatively high negative pressure difference is formed in the dust collecting part and the outside atmospheric pressure. Under the action of this negative pressure difference, the garbage and dust near the suction nozzle enter the vacuum cleaner with the air flow, pass through the filter inside the vacuum cleaner, and the garbage and dust remain in the ash storage box. After being filtered, the air is discharged from the vacuum cleaner into the room, thus completing the entire dust collection process. The current portable dust cup is set at the front end, and the air inlet is set at the front end of the dust cup. The air inlet can be used to connect accessories.

When the vacuum cleaner fan 5 stops, the dust shield 11 can be pushed to rotate by the elastic member, so that the dust shield 11 rotates and resets on the connecting component 10, so that the dust shield 11 can cover one end of the air inlet channel 3, which can prevent the impurities in the dust cup 2 from leaking from the air inlet channel 3.

[0023] Based on the above, the working principle of this solution is as follows:

[0024] When in use, the vacuum cleaner can be picked up by the handle 4 so that one end of the air inlet channel 3 can be aimed at the impurities, and the motor 104 can be controlled by the switch on the handle 4 to drive the vacuum cleaner fan 5 to rotate, so that the vacuum cleaner fan 5 can extract the gas in the dust cup 2 and discharge it through the air outlet 9. At this time, negative pressure is generated in the dust cup 2, which can extract the gas in the air inlet channel 3, and then absorb the impurities, so that the impurities can enter the dust cup 2 through the air inlet channel 3, and are filtered by the filter cotton on the air inlet filter device 6, so that the impurities can accumulate inside the dust cup 2. When a large amount of impurities accumulate in the dust cup 2 and need to be cleaned, the dust cup 2 is locked and removed from the casing 1, which makes it easy to clean the impurities in the dust cup 2.
