Principle and structure of vacuuming

1. The principle of vacuuming. The fan impeller of the vacuum cleaner is driven by the motor at a high speed, and the air in the impeller is discharged from the fan at a high speed, and at the same time, the air in the vacuuming part is continuously replenished into the fan. This may form a higher pressure difference with the boundary. The dust and dirt from the suction nozzle are sucked into the vacuuming part with the air, and leak through the device to collect the dust and dirt into the dust tube.

2. The original of the vacuum cleaner.

All vacuums come with an assembled brush head for cleaning floors and carpets. Suction vacuums also come with a range of brushes and nozzles for cleaning corners, curtains, sofas and crevices.

3. Throat: All suction-type vacuum cleaners will be equipped with hard hoses, which are used to connect soft hoses and accessories for cleaning.

4. Electric brush: The cleaning head of the internal vacuum cleaner is a special accessory of the hybrid vacuum cleaner. 5. Round brush head: It also has a smaller suction nozzle and can be rotated 360*, which is convenient for cleaning furniture, fine mesh fabrics, etc.

6. Flat suction nozzle: also known as gap suction nozzle, it is a slender and flat hard suction nozzle. Especially suitable for cleaning walls, radiant heaters, corners and shallow places.

7. Dust brush: made of long and soft bristles, suitable for cleaning curtains, walls, etc.

The vacuum cleaner is mainly composed of three parts: dust collection, dust collection, and dust filter. Generally, it includes a series-excited commutator motor, a centrifugal fan, a dust filter (bag) and a dust collection accessory. The power of general vacuum cleaners is 400-1000w or higher, and the power of portable vacuum cleaners is generally 250W and below. The vacuum cleaner can remove dust, mainly because its "head" is equipped with an electric exhaust fan. There is a wind impeller on the rotating shaft of the exhaust fan. After the power is turned on, the exhaust fan will generate strong suction and pressure at a speed of 500 revolutions per second. The air in the fan is replenished, causing an instantaneous vacuum inside the vacuum cleaner to form a negative pressure difference with the outside atmospheric pressure. Under the action of this pressure difference, the dust-containing air is inhaled. Dust and other sundries enter the dust filter bag in turn through the carpet or floor brush, long connecting pipe, elbow, hose, and hose joint.
