Description
技术领域
本发明涉及一种用于硬面抽吸机构的抽吸嘴,该抽吸嘴包括具有吸入面的基体,抽吸通道连接于该吸入面,其中,在所述基体的背离所述吸入面的一侧上能连接抽吸机构,用以形成抽吸流,其中,所述基体具有底壁、顶壁和侧壁
背景技术
文首提及类型的抽吸嘴用于清洁或抽吸硬面、特别是用于清洁或抽吸经铺砖的壁、地面、窗玻璃或玻璃门。
这样的抽吸嘴由EP2227126B1已知。预先已知的抽吸嘴具有抽吸口,抽吸通道连接于该抽吸口,其中,在背离抽吸口的一端上能连接抽吸机构。抽吸机构用于形成抽吸流。抽吸通道具有通过侧壁相互连接的底壁和顶壁。这样构造的抽吸嘴具有在整个横截面上不可改变的流速曲线,并且在这些抽吸嘴中,在抽吸嘴的中心中的抽吸作用通常最大。特别是在去除液体时,在抽吸嘴的侧面上在抽吸嘴的底壁和硬面之间的接触区域上出现带状形成和条状形成。
发明内容
本发明的任务在于,提供一种用于硬面抽吸机构的抽吸嘴,该抽吸嘴在抽吸口的整个宽度上具有能有针对性地调节的和/或均匀的流速曲线。此外,通过有针对性地调节的流速曲线应能使用具有尽可能小的功率的抽吸机构。
按照本发明,该任务在所述类型的抽吸嘴中通过如下方法得以解决,即,所述基体通过至少两个中间壁划分成多个抽吸腔。
按照本发明看出,通过由中间壁划分基体可以形成多个抽吸腔。这能实现沿着吸入面调节出不同的流速,由此,可以改进抽吸嘴的清洁效率。
该抽吸嘴可以具有比通到抽吸机构的过渡部宽的抽吸口。由此,当然形成不同长度的流动路径。
以有利的方式,通过中间壁可以使抽吸腔中的流动路径的流动阻力变得均匀。
此外,通过中间壁在抽吸腔中形成抽吸通道。
抽吸腔的几何形状可以选择成,使得能调节预给定的流速曲线。该流速曲线优选调节成,使得在抽吸嘴的侧壁上出现增大的流速,由此,特别在边缘区域中可以改进抽吸嘴的清洁效率。
在所述抽吸腔中可以调节出不同的流速。由此,在吸入面的宽度上最佳地分配流速是可能的。
所述抽吸口优选在侧面上具有较小的流动阻力。由此,提高流速。
按照本发明的另一个优选的实施方式,在抽吸口上的流速是相等的。这导致抽吸功率在吸入面的整个宽度上的均匀分布。
所述中间壁优选设置成扇形的。这种构造方案降低涡流形成,由此,达到小的流动阻力。
所述中间壁还可以设置成波形的或锯齿形的。由此,可以降低涡流形成和流体阻力。
所述中间壁可以彼此隔开不同宽度的间距。这能实现最佳地调节在吸入面上的流速、特别是在抽吸嘴的侧壁上的流速并且流动阻力可以在背离吸入面的排出面上调节。
所述中间壁在所述吸入面上的间距可以比在对置的侧上大。这导致较宽的吸入面,由此,能实现大面积清洁。
按照另一个实施方式,所述中间壁在所述吸入面上的间距可以是等距的。所述中间壁在所述抽吸机构上的间距可以在侧向的通道处选择得比在中间的通道处大。由此,使在所有通道中的流动阻力变得均匀。这导致抽吸功率在吸入面的整个宽度上均匀分布。
所述抽吸嘴可以具有横截面呈矩形的凹槽。根据吸入面上的横截面呈矩形的凹槽的宽度和长度可以调节流速。吸入面上的横截面可以小于在背离吸入面的排出面上的横截面,由此,达到较大的流入速度。
按照一个优选的实施方式,设置有至少一个抽出唇。借助于所述抽出唇,可以特别简单地从硬面擦去液体。
所述密封唇可以具有凹槽。这些凹槽用作通行件。在抽吸嘴在待清洁的面上运动的过程中,所抽出的液体到达抽吸嘴中。
所述抽吸嘴优选在一种设备中使用。这种设备可以包括抽吸嘴、用于形成抽吸流的抽吸机构和污液箱。这能实现卫生且节省时间地清洁硬面,而不出现带状形成和条状形成。在污液箱中收集所及入的液体和所吸入的污物颗粒。抽吸机构用于产生负压,由此,形成抽吸流。由于形成抽吸流,可能吸入液体空气混合物。污液箱优选与该抽吸嘴可拆卸地连接。
所述抽吸嘴可以应用在硬面抽吸机构中、特别是应用在便携式的硬面抽吸机构中。由于在抽吸嘴中的流速可调节,所述抽吸嘴突出地适用于光滑硬面的大面积清洁,例如用于清洁窗、镜或瓷砖。此外,抽吸嘴在硬面抽吸机构中突出地适用于去除硬面上的污物颗粒和液体。
附图说明
附图中:
图1示出抽吸嘴的透视图;
图2示出抽吸嘴的俯视图;并且
图3示出抽吸嘴的剖视图。
具体实施方式
图1示出用于硬面抽吸机构的抽吸嘴1,该抽吸嘴包括具有吸入面3的基体2,抽吸通道连接于该抽洗面,其中,在基体2的背离吸入面3的一侧4上能连接抽吸机构,用以形成抽吸流,其中,基体2具有底壁7、顶壁6和侧壁5a,5b。
抽吸嘴1在吸入面3上具有横截面呈矩形的凹槽9。
抽吸嘴1设有密封唇8和抽出唇12。
图2示出在图1中示出的抽吸嘴1的俯视图。按照一个优选的实施方式,基体2通过中间壁10划分成多个抽吸腔11。
抽吸腔11的几何形状选择成,以便能调节预给定的流速曲线。在各抽吸腔11中能调节出不同的流速。抽吸腔11设计成梯形的。
中间壁10彼此隔开不同宽度的间距。
示出的抽吸嘴1例如可以在硬面抽吸机构中使用。
图3示出抽吸嘴1的剖视图。
可以看出,中间壁10设置成扇形的。中间壁10相对于中间壁10a倾斜地设置。
中间壁10在吸入面3上的间距比在对置的侧上的间距大。中间壁10直线地延伸,由此,避免形成漩涡。
