具体实施方式
实施例一
图3为本发明实施例一地刷整体结构示意图；图4为本发明实施例一密封条在壳体底面上的结构示意图。如图3并结合图4所示，本发明提供一种地刷B，包括壳体100，其内部空腔形成气流通道，壳体底部110上设有用于吸尘的进风口111，地刷B通过连接管200与吸尘器本体(图中未示出)相连。在壳体100的底面110上，位于进风口111的一侧设有密封条，包括：第一密封条，即：毛条300和第二密封条，即： 动皮条400。参照图2所示，密封条113也可以设置在进风口111前、后两侧。为了便于进风吸尘，在毛条300上等距离间隔设有第一开口310，同样地，在动皮条400上也等距离间隔设有第二开口410。更具体地，如图4所示，在壳体100的底面110边缘上，开设有定位槽140，毛条300和动皮条400的端部分别嵌设在该定位槽140内。同时，在壳体底面110上还设有滑槽510，在动皮条400上设置有连接部420，拨钮500通过连接部420与动皮条400相连，并可以在滑槽510内自由滑动，从而带动动皮条400左、右运动，使设置在毛条300上的第一开口310与设置在动皮条400上的第二开口410的位置处于打开、部分遮蔽或完全遮蔽的状态，用于调节进风口111处的气流。例如：当地刷B在平整表面吸尘时，可以使第一开口310和第二开口410对正，使其处于打开状态，地刷可以正常工作；但是当在有缝隙的表面吸尘时，使用者可以通过拨动拨钮500，使第一开口310和第二开口410的位置相互错开，处于部分遮蔽或完全遮蔽的状态，以防止这些开口降低地刷口部的真空度，保证地刷再缝隙处的吸尘效果和工作效率。当然，根据实际需要，第二密封条也可以采用毛条，以提高清洁效率。
实施例二
图5为本发明实施例二密封条在壳体底面上的结构示意图。如图5所示，本实施例与实施例一的不同之处在于第二密封条，即：动皮条400的结构和运动方式。具体来说，在本实施例中，第一密封条，即：毛条300上仍设有第一开口310，但动皮条400则为整体的条状体。动皮条400通过连接部420与按钮600相连，通过下压或提拉按钮600的方式，可以使动皮条400上、下移动，从而使毛条300上的第一开口310处于打开、部分遮蔽或完全遮蔽的状态。
本实施例的其他技术特征与实施例一相同，在此不再赘述。
实施例三
图6和图7为本发明实施例三密封条在升降板上的结构示意图。如图6并结合图7所示，本实施例是在实施例一基础上的改进。在背景技术中已经提到，地刷的壳体100还可以包括有升降板130，在本实施例中，密封条的设置位置进一步设置在该升降板130上。与前述两个实施例相同的是，同样可以在升降板的一侧边缘设置定位槽131，用于密封条在壳体升降板上的定位。在本实施例中，密封条的数量有所改变，具体来说，第一密封条包括了毛条300和定皮条700，第二密封条为动皮条400。如图6所示，动皮条400和定皮条700的设置位置相对更加贴近，且在毛条300和定皮条700上设有第一开口310，动皮条400上设有第二开口410。同时，在升降板130上还设有滑槽 510，在动皮条400上设置有连接部420，拨钮500通过连接部420与动皮条400相连，并可以在滑槽510内自由滑动，从而带动动皮条400左、右运动，使设置在毛条300和定皮条700上的第一开口310与设置在动皮条400上的第二开口410的位置处于打开、部分遮蔽或完全遮蔽的状态，用于调节进风口111处的气流。比如：可以使设置在毛条300和定皮条700上的第一开口310的位置对正，如图6所示的状态下，第二开口410和定皮条上的第一开口310是遮挡的，而如图7所示的状态下，第二开口410和定皮条上的第一开口310是打开的，可以从第一开口310和第二开口410的位置进气。
本实施例的其他技术特征与实施例一相同，在此不再赘述。
实施例四
图8和图9为本发明实施例四密封条在升降板上的结构示意图。如图8并结合图9所示，本实施例与实施例三的不同之处在于用刷条800取代了实施例三中的毛条300，定皮条700作为第一密封条，其上开设有第一开口310，动皮条400作为第二密封条，其上开设有第二开口410，仅仅是通过拨钮500带动动皮条400的左右移动，使设置在动皮条400上的第二开口410与设置在定皮条700上的第一开口310的位置处于打开、部分遮蔽或完全遮蔽的状态，用于调节进风口111处的气流。
本实施例的其他技术特征与实施例三相同，在此不再赘述。
实施例五
图10和图11为本发明实施例五密封条在升降板上的结构示意图。如图10并结合图11所示，本实施例与实施例三的不同之处在于动皮条400的结构和运动方式。具体来说，在本实施例中，第一密封条包括了毛条300和定皮条700，两者都开设有第一开口310，但第二密封条，即：动皮条400则为整体的条状体。动皮条400与按钮600相连，通过下压或提拉按钮600的方式，使设置在毛条300和定皮条700上的第一开口310的位置处于打开、部分遮蔽或完全遮蔽的状态，用于调节进风口111处的气流。比如：可以设置位于毛条300上的第一开口310和位于定皮条700上的第一开口310的位置是对正的，如图10所示的状态下，下压按钮600使动皮条400处于下方，将位于两处的第一开口310遮挡住；而如图11所示的状态下，提拉按钮600使动皮条400处于上方，使位于两处的第一开口310是打开的，可以从两者的开口位置进气。
本实施例的其他技术特征与实施例三相同，在此不再赘述。
实施例六
图12和图13为本发明实施例六密封条在升降板上的结构示意图。如图12和图13所示，本实施例与实施例四的不同之处在于在升降板130上只设置了第一密封条， 即：定皮条700和第二密封条，即：动皮条400，没有刷条800。通过拨钮500在滑槽510中的左右移动，从而带动动皮条400的左右移动，使设置在动皮条400上的第二开口410与设置在定皮条700上的第一开口310的位置处于打开、部分遮蔽或完全遮蔽的状态，用于调节进风口111处的气流。
本实施例的其他技术特征与实施例四相同，在此不再赘述。
另外，由上述六个实施例可知，动皮条400的运动是通过直接与其连接的开关实现的，如果动皮条的运动方向是左右方向，则与拨钮500相连，如果动皮条的运动方向是上下方向，则与按钮600相连。在背景技术中提到，壳体100还包括有升降板，该升降板通过设置在壳体100上的踏板120来控制其上、下运动。因此，实际上在需要相应的密封条上下运动时，也可以不再设置单独的开关，而是利用现有的踏板120，通过设置与踏板的联动机构，在完成升降板上下运动的同时，也可以实现对动皮条400的上下运动控制。由于踏板120控制升降板属于现有技术，对其具体结构可参见美国专利文献：US 3952363，在此不再赘述。再有，为了保证地刷的清扫效果和工作效率，在设置了第一密封条和第二密封条的基础上，实施例四中还出现了刷条800，设置在壳体底面或者升降板上。
本发明还提供一种吸尘器，包括吸尘器本体和地刷，两者之间通过连接管相连，所述地刷为上述六个实施例中任一个所述的吸尘器地刷。综合上述六个实施例可知，本发明的主要发明构思实际上是通过设置在壳体底面或升降板上的密封条的不同运动方式的组合，来实现对进风口气流的调节。其中的密封条包括设有开口的第一密封条和能上下或左右运动的第二密封条，同时，第一密封条和第二密封条可以是毛条和/或皮条的多种组合，因此，在上述实施例中，第一密封条实质上包括了毛条300和定皮条700，而第二密封条则包括动皮条400。因此，本发明通过设置在地刷壳体或壳体升降板上的毛条和不同数量的皮条的组合方式，以及毛条和皮条上开口和/或不开口的组合方式，使毛条、动皮条和定皮条上的开口选择性的打开或关闭，实现对进风口的气流调节。对于平整表面可以打开开口，而当清洁缝隙或者其它情况需要提高地刷真空度时，则可以关闭开口，无论在何种工作表面，都可以获得适当的进风和真空度，能够适应不同的作业表面要求，提高清洁效果和工作效率。
