摘  要
 
 本次論文主要分析的吸塵器的工作原理和檢驗過程，吸塵器能除塵，主要在于它的“頭部”裝有一個電動抽風機。抽風機的轉軸上有風葉輪，通電后，抽風機會以每秒500圈的轉速產生極強的吸力和壓力，在吸力和壓力的作用下，空氣高速排出，而風機前端吸塵部分的空氣不斷地補充風機中的空氣，致使吸塵器內部產生瞬時真空，和外界大氣壓形成負壓差，在此壓差的作用下，吸入含灰塵的空氣。灰塵等雜物依次通過地毯或地板刷、長接管、彎管、軟管、軟管接頭進入濾塵袋，灰塵等雜物滯留在濾塵袋內，空氣經過濾片凈化后，由機體尾部排出。吸塵器產品依據國家標準GB4706.7—1999《家用和類似用途電器的安全 真空吸塵器和吸水式清潔器的特殊要求》和通用標準GB4706.1—1998《家用和類似用途電器的安全通用要求》進行安全項目檢驗，適用范圍是額定電壓不超過250V的家用和類似用途的真空吸塵器和吸水式清潔器。

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.
