Handheld vacuum cleaner operating principle
The main components of handheld vacuum cleaner are vacuum pumps, dust collecting bags, hoses and nozzles of various shapes.
The handheld vacuum cleaner has an electric suction fan inside that pushes air all the way to the exhaust port as the fan blades rotate.When air particles are pushed forward, the particle density in front of the fan increases, the air pressure increases accordingly, and the particle density behind the fan decreases.The pressure drop behind the fan is the same as that in the pipette when you suck a beverage.The pressure behind the fan is lower than that outside the vacuum cleaner, i.e. ambient pressure.This produces suction inside the vacuum cleaner, i.e. a partial vacuum, which makes the internal pressure of the handheld vacuum cleaner much lower than that of the outside. Under this pressure difference, dust and dirt enter the handheld vacuum cleaner with the airflow and are filtered. The dirt remains in the dust collection area, while the purified air enters the room again via the electric motor.It plays the role of cooling motor and purifying air.
Handheld vacuum cleaner is a lightweight, easy-to-use, portable design that allows easy suction as long as it is lifted by hand and gently pressed by hand.
Use a large suction head to suck anything on the ground (except water), a wide type of suction head to suck anything with gaps (the head of the wide suction head has a bristle sweep to remove dust in the gaps), not only sofas, curtains, but also ceilings, computer keyboards, beds and various surfaces of household appliances.Handheld vacuum cleaner can also be equipped with a small turning square brush for computer keyboard dust removal, small debris removal and pet dust removal, dirt removal hidden in each dead corner slot, improving cleaning efficiency and ease of use.
