相关申请的交叉引用
本申请要求于2014年6月13日提交的编号为14/304,576,名称为真空吸尘器刷驱动器的美国专利申请(律师案卷号为ARSL-32687)的优先权,在此将其说明书全部并入本文。
技术领域
本发明一般地涉及与真空吸尘器相关联的动力刷。
背景技术
真空吸尘器有多种形式,一般是立式或卧式。大多数现代立式真空吸尘器上设置有动力刷,并且许多卧式吸尘器具有包括被驱动的刷子的动力头。被驱动的刷子对于清除表面的碎片可能是重要的,使得碎片可以被吸入真空吸尘器中,而不是仅保持附着在被清洁的表面。
已知真空吸尘器具有声音大的问题。过度的噪声会刺激真空吸尘器的操作者及附近的其他人。因此,一些制造商已经致力于降低他们的真空机组的噪声。由于他们降低了真空吸尘器的电机和吸入方面的噪声,因此由刷驱动器产生的噪声变得更加引人注意。刷驱动系统通常使用皮带而不是链条或齿轮。这些皮带通常是简单的正方形齿状带,因为这样的皮带保证刷子以设计的速度转动而不打滑,但负载完全在这些皮带的扭矩极限内。这些正方形齿状带是相当安静的,但用于现代真空吸尘器时,它们的噪声较为引人注意。
因此,需要一种用于真空吸尘器的更安静的刷驱动器,但不会降低动力刷的性能。
在法律允许的最大程度内将本文所引用的所有参考文献以引用的方式并入本文。在参考文献不允许被全部并入本文的情况下,在此以作为背景技术的目的将其以引用的方式并入,表示本领域普通技术人员的知识。
发明内容
通过提供一种用于真空吸尘器刷的驱动系统,所述驱动系统使用带有圆形齿的驱动皮带,解决了典型的真空吸尘器刷驱动系统中存在的问题。
描述了一种真空吸尘器,所述真空吸尘器具有真空吸尘器头,所述真空吸尘器头具有壳体、吸入口、电机和刷子。所述刷子被连接至驱动皮带轮,所述电机具有电机小齿轮,皮带从所述电机小齿轮延伸至所述驱动皮带轮,所述皮带具有带有圆形轮廓的齿。
参考附图和以下详细描述,本发明的其他目的、特征和优点将是明显的。
附图说明
图1是真空吸尘器头的平面图,其中真空吸尘器头的壳体的顶部被移除;
图2是真空吸尘器头的局部透视图,示出刷驱动系统的配置;
图3是真空吸尘器头的侧面剖视图;
图4是驱动皮带轮的透视图;和
图5是真空吸尘器头的放大侧面剖视图。
具体实施方式
在法律允许的最大程度内将本文所引用的所有参考文献以引用的方式并入本文。在参考文献不允许被全部并入本文的情况下,在此以作为背景技术的目的将其以引用的方式并入,表示本领域普通技术人员的知识。
在关于优选实施例的以下详细描述中,参考形成该描述的一部分的附图,并且其中以说明的方式,示出了可以实施本发明的具体的优选实施例。充分详细地描述了这些实施例,使得本领域技术人员能够实施本发明,将理解的是,可以使用其他实施例并且在不脱离本发明的精神和范围的情况下可以做出逻辑、机械和电学上的变化。为了避免对于本领域技术人员能够实施本发明不必要的细节,该描述可以省略本领域技术人员已知的某些信息。因此,以下详细描述并不被视为是限制性的,并且本发明的范围仅由所附权利要求限定。
图1是真空吸尘器头10的平面图,其中真空吸尘器头的壳体12的顶部被移除。壳体12容纳刷子14和吸入口16,吸入口16通向吸入单元(未示出)。该实施例的壳体12被配置为用于卧式真空吸尘器的动力头。驱动电机18通过电机小齿轮20连接至刷子14,电机小齿轮20驱动被附接至电机小齿轮20和刷驱动皮带轮24的皮带22。电机18使小齿轮20转动,进而使皮带22转动,皮带22驱动被附接至刷子14的皮带轮24。从该视图难以确定皮带22的轮廓。
图2是真空吸尘器头10的局部透视图,示出刷驱动系统的配置。示出了壳体12的局部,以显示正在讨论的部件。示出了电机18的一部分,而小齿轮20、皮带22和皮带轮24相对于刷子24更清楚地示出。从该视图,皮带22的轮廓差不多是可分辨的。
图3是真空吸尘器头10的侧面剖视图,给出了电机18、小齿轮20、皮带22、驱动皮带轮24和刷子14的布置的另一透视图。从该视图可以清楚地看出,皮带22具有带有圆形轮廓的齿26。皮带22具有圆形齿26。圆形齿的齿距(峰与峰的间距)是0.005英寸至0.300英寸,齿距通常是大约0.120英寸,例如盖茨(Gates)#T31-048-0118H的齿距是0.118英寸。
图4是驱动皮带轮24的透视图,示出凹形轮廓28,用以匹配皮带22的圆形齿26。皮带轮24还具有主轴30和翼32,以与刷子14接合。
图5是驱动皮带轮24和皮带22的侧视图。圆形齿26和凹形轮廓28相对于彼此清楚地示出。当皮带的齿26与轮廓28啮合时,由于圆形形状,两者之间有很少扭曲或干扰。最初,该形状被设计用以减少皮带齿上的应力,增加齿状带可以承受的负载,但本发明使用这种轮廓不是用于增加负载能力,而是用于减少噪声。
即使本申请中所示出的实施例是在卧式真空吸尘器的动力头中,但是相同的驱动系统可以应用于其他真空吸尘器刷驱动器,以减少皮带驱动系统产生的噪声。
由前述内容应当明显地看出,已提供了具有显著优点的发明。虽然本发明仅以其形式中的几种被示出,但本发明并不仅限于此,而是在不脱离其精神的情况下,易于进行多种改变和变形。
