Second, the principle of sweeper
1.？ Through the high-speed rotation of the motor, a vacuum is formed in the main engine, and the generated high-speed airflow is used to suck the garbage out of the suction port. At this time, the airflow speed is as high as 240 revolutions per hour, and pests such as lice will die when they enter the main engine.
2.？ The garbage sucked into the sweeper is stored in the bag machine, and the air purified by the filter is discharged from the sweeper while cooling the motor.
3.？ Motor is the heart of sweeper, and its performance directly affects the reliability of sweeper. In addition, the motor used by the sweeper is 20,000 to 40,000 revolutions per minute. For example, the motor speed of an electric fan is about 1800 ~ 3600 rpm, 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 (wattage or amperage), but the output power (suction).
5. "Suction" depends on the resultant force of wind force and vacuum force, but these two factors have opposite characteristics. That is to say, when the wind is strong, the vacuum force becomes weak, and when the vacuum is strong, the wind force becomes smaller. The maximum value of the resultant force of the two, that is, the "suction" representing the ability of the sweeper, is expressed in watts (W). This definition is an international standard for the performance of sweepers stipulated by the International Organization for Standards (ISO), which has been recognized all over the world. At present, Japan, Germany and other countries all use this unit as the unit to express the performance of the sweeper, while in other regions, the input power is directly misunderstood as the unit to express the performance of the sweeper.
The price of sweeper will be different because of different brands and different functions. There are many factors that affect it. If you want to save the trouble of cleaning and sweeping the floor, you can buy one to go home.
