Description

Technical Field

[0001] The utility model relates to the field of vacuum cleaners, in particular to an anti-deformation plastic shell of a vacuum cleaner. Background Art

[0002] The vacuum cleaner is mainly composed of three parts: dust collection, dust collection, and dust filtration. It generally includes a series commutator motor, a centrifugal fan, a dust filter (bag), and dust collection accessories. 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 power is turned on, the exhaust fan will generate high suction and pressure at a speed of 500 revolutions per second. Under the action of suction and pressure, the air is discharged at a high speed, and the air in the dust collection part at the front end of the fan continuously replenishes the air in the fan, causing an instantaneous vacuum inside the vacuum cleaner, forming a negative pressure difference with the external atmospheric pressure. Under the action of this pressure difference, dust-containing air is inhaled, and dust and other debris are retained in the dust filter bag. The air is purified by the filter and then discharged from the tail of the machine body.

[0003] Usually, the shell of a vacuum cleaner is made of plastic material, which has low strength and is easily damaged when subjected to external impact, causing the shell surface to crack and expose internal devices or damage internal devices.
