Working principle of household handheld vacuum cleaner
The hand-held 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 on, the exhaust fan generates pressure at a speed of 500 revolutions per second. Under the action of pressure, the air is quickly discharged, and an instantaneous vacuum is generated inside the vacuum cleaner, which causes the external pressure to be stronger than the internal pressure of the vacuum cleaner, forming a pressure difference.
Therefore, the air at the front end of the vacuum cleaner is sucked into the vacuum cleaner to continuously replenish the air in the fan, while carrying a large amount of garbage into the handheld vacuum cleaner. Then it enters the dust filter bag through the long connecting pipe, elbow pipe, hose, and hose joint, and dust and other garbage will eventually stay in the dust filter bag.
