Vaccum cleaners are use for sucking dirt, dusts and liters.
Vacuum cleaners are one of the most handiest household cleaning appliances used today. Its simple yet effective design has done away with having to clean dust and other small particles off surfaces by hand, and turned house cleaning into a more efficient and fairly rapid job. Using nothing but suction, the vacuum whisks away dirt and stores it for disposal.
It consists of a fan which makes the vaccum, a filter and an attachment.
The fan produce suction by means of an electric motor which spins the blade at high speed to draw air out of the vaccum cleaner through an attachment (opening). So we are going learn how to make a vacuum cleaner out of can.
Materials needed.
- Coca-Cola can
- Switch
- DC motor
- 9v battery
- Wires
- A piece of net
- Fan blades.
Tools needed.
- Soldering iron
- Hot glue gun
- Sharp paper
- Cutter.
Working principle of a vacuum cleaner.
Materials flow from one location to another when a pressure difference is created between two locations. This phenomenon is the basic working principle of an ideal vacuum cleaner. When a centrifugal fan rotates it makes the air to flow by adding it external kinetic energy. Air is sucked from behind and pushed forward with pressure and so negative pressure it creates behind the fan. An ideal vacuum cleaner has such centrifugal fan in it connected to a motor. This unit has suction and discharge connections, on the suction side filter bag is fitted before the hose connection.
The discharge has another air purifier filter and opened to the atmosphere. When the electric power is given the motor rotates and so the centrifugal fan. Air from the suction side is sucked into the unit, along with the air all air born particles, cat allergen, mist, dirt, and small solid particles are carried to the suction filter. They are trapped in the filter and dirt free air is pushed out from the discharge opening.
