Abstract
This thesis mainly analyzed the working principle of vacuum cleaners and inspection processing, the vacuum cleaner to dust, mainly in its "head" with an electric exhaust fan. Exhaust fan impeller shaft of the wind, power, the exhaust fan will lap speed of 500 per second produced a very strong suction and pressure, the suction and pressure, the air speed discharge, while cleaning the front part of the air blower continuously supplement the fan in the air, causing instantaneous vacuum cleaner internally generated, and the formation of the external atmospheric pressure difference of the negative pressure in this role, the inhalation of dust containing air. Dust and other debris followed by carpet or floor brush, long over, elbows, hose, hose connector into the Dust bags, dust and other debris stuck in the Dust bags, air purified by the filter from the body from the rear. Vacuum cleaner according to the national standard GB4706.7-1999 "Household and similar electrical appliances vacuum cleaners and water suction cleaning appliances for special requirements," and common standards GB4706.1-1998 "Household and similar electrical appliances general requirements" for safety project inspection, the scope is the rated voltage not exceeding 250V for household and similar purposes vacuum cleaners and water suction cleaning appliances.
