Why to say long life vacuum cleaner motor, which has been around for 100 years, has become an essential household appliance for many people.The current controls the operation of the motor.A fan is attached to the motor, and the fan blade has a certain Angle, just like the propeller of an airplane.As the fan blades rotate, they push air all the way to the vent.As air particles are pushed forward, the density of particles in front of the fan increases, so does the air pressure, and the density of particles behind the fan decreases.The pressure drop behind the fan is just like the pressure drop in the straw when you suck a drink.The pressure behind the fan is lower than the pressure outside the vacuum cleaner, the ambient air pressure.This creates suction, or partial vacuum, inside the vacuum cleaner.
The main components of modern vacuum cleaners are vacuum pumps, dust collecting bags, hoses and tubes of various shapes.Inside the machine has an electric extractor fan, after electrify at high speed, instant make vacuum forming inside the vacuum, the internal air pressure is much lower than the outside world, in this under the action of pressure difference, dust and dirt with airflow into the vacuum barrel body, and then after dust bag filter, the dirt in the dust bag, purify air, through the motor to escape into the room, have the effect of cooling motor, purify air.
