With the development of artificial intelligence technology, smart appliances have also entered millions of households. As a new type of household appliance, floor cleaning robots have become increasingly well-known to more and more people!
So, what is the working principle of a vacuum cleaner? What mysteries are hidden inside? Let’s take a look together today!
Working principle of robotic vacuum cleaner
1. By the high-speed rotation of the electric motor, a vacuum is formed inside the host, and the high-speed airflow generated is used to suck in garbage from the suction port. At this point, the airflow reaches a speed of 240 revolutions per hour, and pests such as lice enter the main unit and die due to high-speed collisions with the inner wall of the vacuum tube.
2. The garbage sucked into the sweeping machine is accumulated in the bag machine, and the air that has been purified by the net is discharged from the sweeping machine while the electric motor is turned off. The electric motor is the heart of the vacuum cleaner, and its performance can directly affect the reliability of the vacuum cleaner. In addition, the electric motor used in the sweeping machine rotates 20000 to 40000 revolutions per minute. And like the electric motor of a fan, its speed is about 1800-3600 revolutions per minute, which shows how high the speed of the sweeping machine motor is.
4. The correct unit for expressing the performance of a floor sweeper is not input power (watts or amperes), but output power (suction power).
5. The suction force depends on the combined force of the generated wind force and vacuum force, but these two factors have opposite characteristics. That is to say, when the wind is strong, the vacuum force weakens, and when the vacuum force is strong, the wind force decreases. The maximum value of the combined force of these two represents the suction power of the sweeping machine, which is expressed in watts (W). This definition is an international standard established by the International Organization for Standardization (ISO) to represent the performance of floor sweepers, which is recognized worldwide in China. At present, Japan, Germany, and other countries use this unit to represent the performance of a sweeping machine, but in other regions, the input power is directly misunderstood as a unit to represent the performance of a sweeping machine
The cooling fan inside plays a decisive role in the operation of the sweeping machine
The 10025 and 12025 circular cooling fans produced by Fengheng Technology are specialized fans for floor cleaning machines, with high air volume, strong suction, and low noise. They are one of the essential accessories for floor cleaning robots.
