When the vacuum cleaner is powered on, the motor directly drives the fan to generate high-speed rotation, and the fan impeller drives the air to be discharged to the outside of the casing at a very high speed. At this time, a partial vacuum is formed in front of the fan, which makes the interior of the vacuum cleaner and the outside world produce a high negative Pressure difference, under the action of this negative pressure difference, the dust-containing gas next to the suction nozzle is continuously replenished to the fan, and through the suction nozzle and the pipe, the air full of dust and dirt is sucked into the dust collection chamber of the vacuum cleaner, Filtered to keep dust and dirt in the dust chamber. The filtered clean air is discharged from the rear air outlet of the fan and motor, and sent back into the room to achieve the purpose of vacuuming.

The function of the vacuum cleaner circuit is to control the on-off of the motor. The motor of the vacuum cleaner has one-speed, two-speed and stepless speed regulation. Motor speed control can be achieved through switch circuits and electronic speed control circuits.
