Abstract: The present invention provides an airflow control mechanism comprising a conduit for air having an inlet located at a first end thereof and an outlet located at a second end thereof; a first opening formed in a side of said conduit and able to provide a secondary inlet thereto; a movable collar at least partially surrounding said conduit at a location alignable with said first opening, such that said collar is able to at least partially occlude said first opening; further comprising a second opening beside the first opening as part of the secondary inlet, wherein the collar is also alignable with the second opening, such that the collar is able to at least partially occlude the second opening at the same time as the first opening. Thus with this airflow control mechanism, a user may select whether to occlude both the first and the second openings, in which case air will pass directly from the inlet to the outlet without any air also entering through the secondary inlet, or to occlude neither the first and second openings, in which case air entering the secondary inlet will contribute to the total amount of air exiting the outlet, or to occlude just one of the first and second openings, in which case, a fixed amount of air which is less than the secondary inlet being fully open, but more than the secondary inlet being fully closed, will enter through the secondary inlet and contribute to the total amount of air exiting the outlet. Thus the user will be provided with a highly predictable and repeatable setting for the airflow control mechanism between the fully open and fully closed positions of the secondary inlet.

Abstract translation: 本发明提供了一种气流控制机构，其包括用于空气的导管，其具有位于其第一端处的入口和位于其第二端处的出口; 第一开口形成在所述导管的一侧，并能够向其提供次级入口; 至少部分地围绕所述管道在与所述第一开口对准的位置处的可移动轴环，使得所述套环能够至少部分地封闭所述第一开口; 还包括作为所述次级入口的一部分的所述第一开口旁边的第二开口，其中所述套环还可与所述第二开口对准，使得所述套环能够在与所述第一开口同时至少部分地封闭所述第二开口。 因此，利用这种气流控制机构，用户可以选择是否闭塞第一和第二开口，在这种情况下，空气将直接从入口通向出口，而没有任何空气也通过次级入口进入，或者不阻塞 第一和第二开口，在这种情况下，进入次级入口的空气将有助于离开出口的空气的总量，或仅阻塞第一和第二开口中的一个，在这种情况下，固定量的空气小于 次级入口完全打开，但是比次级入口完全关闭的次级入口将通过次级入口进入，并有助于离开出口的空气的总量。 因此，用户将被提供用于次级入口的完全打开和完全关闭位置之间的气流控制机构的高度可预测和可重复的设置。

Abstract: A cleaning tool having a clamp-on handle assembly. The clamp-on handle assembly includes a slidable locking element which can be moved from an open position, wherein the handle assembly can be placed over a handle portion of the cleaning tool, to a locked position wherein the locking element clamps the handle assembly securely onto the handle portion of the cleaning tool. Advantageously, no external tools or fastening implements are required to secure the handle assembly to the handle portion of the cleaning tool. The handling assembly allows the user to use the cleaning tool to reach elevated areas or other areas that would be difficult to reach with the user holding directly onto the handle portion of the cleaning tool.
