Cleaner Robot Vacuum
Principle of sweeping robot
1. Through the high-speed rotation of the motor, a vacuum is formed in the host, and the resulting high-speed air flow is used to suck garbage from the suction port. At this time, the speed of the air flow is as high as 240 revolutions per hour. When lice and other pests enter the host, they die due to high-speed collision with the inner wall of the dust suction pipe.
2. The garbage sucked into the sweeper is stored in the bag machine. The air purified by the filter screen is discharged from the sweeper while cooling the motor.
3. Motor is the heart of sweeper. Its performance can directly affect the reliability of sweeper. In addition, the motor used by the sweeper rotates 20000 ~ 40000 revolutions per minute. For example, the motor speed of the electric fan is about 1800 ~ 3600 revolutions per minute, which shows how high the motor speed of the sweeper is.
4. The unit that correctly represents the performance of the sweeper is not the input power (watts, or Amperes), but the output power (suction power).
5. "Suction force" depends on the resultant force of wind and vacuum force, but these two factors have opposite characteristics. In other words, when the wind force is large, the vacuum force becomes weak, and when the vacuum force is strong, the wind force becomes small. The maximum value of the resultant force of the two represents the "suction power" of the sweeper capacity, and the suction power is expressed in watts (W). This definition is an international standard for the performance of floor sweepers stipulated by the international standards organization (ISO), which is recognized all over the world
