Vacuum cleaner front cover mould

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 high 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.
