The function of the vacuum cleaner is to use the motor to drive the blade to rotate at a high speed, generate negative air pressure in the sealed shell, and absorb dust.
The basic structure of vacuum cleaner is divided into five parts according to its function:
1. Power part: Vacuum cleaner motor and governor. Governor break-up control and machine control.
Motor: There are copper wire motor and aluminum steel motor.
Copper wire motor has the advantages of high temperature resistance, long service life, long single operation time and so on, but the price is higher than that of aluminum steel;
Aluminum steel motor has the characteristics of low price, but the thermal endurance is poor, the melting point is low, and the service life is not as long as copper wire.
Speed Controller: manual control type is generally throttle adjustment (as shown in the figure);
The machine-controlled type is power-powered handheld button or infrared adjustment.
2. Filter system: dust bag, front filter, rear filter. Divided by filter material: paper, cloth, SMS, HEPA efficient filter material.
3. Functional part: take-off mechanism, dust full indication, button or slide switch.
4. Protection measures: no dust bag protection, high vacuum degree protection, anti-interference protection (soft start), overheating protection, anti-static protection.
5. Accessories: handle and hose, pipe, floor brush, flat vacuum cleaner, round brush, bed sheet brush, sofa suction, Hook, strap.
6. Dust collection principle: the fan propeller of the vacuum cleaner drives the air in the impeller out of the fan at high speed under the high speed of the motor, and at the same time, the air in the dust collection part is continuously supplemented into the fan. In this way, a higher pressure difference may be formed with the outside world. The dust and dirt of the suction nozzle are sucked into the suction part along with the air, and the dust and dirt are collected in the dust cylinder through the leakage device.
7. Original vacuum cleaner: most vacuum cleaners are equipped with an assembled Bruch head for cleaning floors and carpets. Suction vacuum cleaners will also be equipped with a series of cleaning brush and suction nozzles for cleaning corners, curtains, sofas and gaps.
8. Pipework: all suction vacuum cleaners are equipped with hard pipework, which is used to connect the soft pipework and accessories for cleaning.
9. Electric brush: the cleaning head of the inner vacuum cleaner is a special accessory of the hybrid vacuum cleaner.
10. Round brush head: Also small suction nozzle, can do 360 * rotation, convenient cleaning furniture, fine mesh fabric, etc.
11. Flat nozzle: also known as gap suction nozzle, it is a slender and flat hard suction nozzle. It is especially suitable for cleaning wall edges, radiant radiator, corners and shallow and narrow places.
12. Dust brush: made of long and soft mane, suitable for cleaning curtains, walls, etc.
