In the dust collection chamber 54.

繼續，氣流會再流經該集氣室451而進入該內通管30的內孔31，並再經過該過濾單元70的濾除，則可使潔淨氣流由該驅動單元60的引入口61吸入，並由該排風部62排出，且最後再由該等出風孔112排出至該外殼單元10的外部。Continuing, the airflow will flow through the plenum 451 and enter the inner hole 31 of the inner tube 30, and then filtered by the filter unit 70, so that the clean air stream can be sucked in through the introduction port 61 of the driving unit 60. And discharged from the exhaust portion 62, and finally discharged to the outside of the outer casing unit 10 by the outlet holes 112.

因此，本新型利用該內通管30沿呈直立狀的該軸線L延伸，所以當該驅動單元60啟動時，該內通管30內部的抽風阻礙小，可相對降低該驅動單元60所需功率，進而可提昇集塵效果。且利用該內通管30與該渦流單元40、該濾網20的配合，可產生較佳之吸塵效果。Therefore, the present invention utilizes the inner through tube 30 to extend along the axis L in an upright shape. Therefore, when the driving unit 60 is activated, the exhausting force inside the inner through tube 30 is small, and the power required by the driving unit 60 can be relatively reduced. In turn, the dust collecting effect can be improved. Moreover, by using the inner tube 30 to cooperate with the vortex unit 40 and the screen 20, a better dust suction effect can be produced.

綜上所述，本新型旋風式吸塵器，相較於現有的吸塵器，確實已可解決技術問題，並可產生不可預期的功效，確實能達成本新型之目的。In summary, the novel cyclone vacuum cleaner can solve the technical problem and can produce unpredictable effects compared with the existing vacuum cleaner, and can truly achieve the purpose of the present invention.

惟以上所述者，僅為本新型之實施例而已，當不能以此限定本新型實施之範圍，凡是依本新型申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本新型專利涵蓋之範圍內。However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
