Description

防止因漏装滤芯导致垃圾吸入清洁设备的保护结构 技术领域
本发明属于清洁设备领域，具体涉及防止因漏装滤芯导致垃圾吸入清洁设备的保护结构。
背景技术
在两个连通的空间之间，如果彼此之间的内容物的密度不等，则高密度内容物会流向向低密度内容物，利用这一原理制造出了吸尘器和水下清洁机器人，它们都是利用电机和叶轮的工作产生负压，吸尘器的叶轮促使外界的空气涌向叶轮，同时将灰尘和垃圾带进设备内的滤芯中，水下清洁机器人则是通过叶轮促使外界的水涌向叶轮，同时水底的垃圾带进设备内的滤芯中，再将过滤后的水排出设备。
在公开号为CN208228904U，专利名为“一种适用于水下作业的吸尘器”的中国发明专利中，就公开了一种适用于水下作业的吸尘器，包括配装有泵体装置和过滤装置的后机体，以及安装在后机体前端并用于输送污物的前机体，泵体装置的尾端配接有电源组件，过滤装置为罩状结构且配接于后机体的尾端，后机体的内壁设有用于固定泵体装置的支撑架，支撑架设有供垃圾通过的通道，泵体装置包括用于制造负压的叶轮，过滤装置和叶轮之间设有单向阀，过滤装置和单向阀之间构成有用于存储污物的垃圾仓。因此，垃圾会顺次通过前机体、叶轮、单向阀，直至到达作为过滤装置的滤芯，这种结构的垃圾会污染叶轮，对叶轮造成冲击。
在公开号为CN208153389U，专利名为“水下清洁机器人泵水结构”的中国发明专利中，就公开了水下清洁机器人泵水结构，包括壳体组件，壳体组件内部设有第一腔体和第二腔体，第一腔体的上方设有开口于壳体组件的排出口，第一腔体和第二腔体之间设有通道，第一腔体内固设有叶轮，叶轮包括朝向排出口的叶轮；第二腔体底部设有开口于壳体组件的吸污口，第二腔体中设有对接于吸污口的过滤装置。第二腔体的内壁与过滤装置之间设有间隙。垃圾通过吸污口进入过滤装置，并滞留在过滤装置内，而过滤后的水则经通道进入第一腔体，直至从排出口排出。相较于公开号为CN208228904U的专利，优点是大颗粒垃圾不会对叶轮造成直接冲击和污染，也不会对第一腔体和第二腔体造成直接污染。
但是，公开号为CN208153389U的结构缺点是一旦忘记安装过滤装置，在工作时，外界的垃圾会大量涌入第一腔体和第二腔体，造成严重的、难以清理的污染。
发明内容
本发明所要解决的技术问题是针对上述现有技术的现状，而提供结构合理、清洁维护维护方便的防止因漏装滤芯导致垃圾吸入清洁设备的保护结构。
本发明解决上述技术问题所采用的技术方案为：防止因漏装滤芯导致垃圾吸入清洁设备的保护结构，包括机壳，机壳内设有容纳叶轮的第一腔体，以及容纳滤芯的第二腔体，第一腔体连通有排出口，第二腔体连通有吸污口，第一腔体和第二腔体之间通过第一通道相连，还设有连通第二腔体和外界的第二通道,第二通道的数量为1个以上，滤芯设有用于阻断第二通道的堵件。
本发明结构适用于旱地吸尘器，也适用于水下垃圾清洁器。拥有叶轮的清洁机器人是靠叶轮的转动在第一腔体内产生的负压，使外界的流体通过吸污口压入第二腔体，垃圾会被滤芯阻挡，过滤后的水或空气则会进入第一腔体，直至从排出口排至外界。滤芯和吸污口之间的容腔是用来聚集垃圾的。
吸尘器和水下清洁机器人这类负压式清洁设备的工作原理是靠负压将外界流体压入设备内，但人们通常习惯称为“将流体吸进设备内”，本发明迁就通常习惯，凡出现“吸”的概念都通“压”。
以水下清洁器为例，当第二腔体中忘记装入滤芯，在叶轮工作时，外界的水会通过第二通道涌入第二腔体，随即通过第一通道涌入第一腔体，直至从排出口排回外界水体中，由于叶轮产生的负压会被第二通道涌入的水体所填补，所以吸污口受到的负压会大幅削弱，从而减小或避免垃圾从吸污口吸入第二腔体甚至垃圾涌入第一腔体污染叶轮。本发明能有效避免因漏装滤芯导致垃圾吸入清洁机器人。
在优选的方案中，机壳包括主壳体和副壳体，主壳体和副壳体之间通过可拆卸结构对接，第一腔体和排出口位于主壳体上，吸污口位于副壳体上；主壳体设有隔板，第一通道位于隔板上。可拆卸结构的实施方案有很多，常见的有凹凸卡扣式、螺纹配接形式等都属于现有技术。隔板作为第一腔体和第二腔体的分界。
在优选的方案中，副壳体和隔板之间设有环状间隔，环状间隔连通第二通道，堵件为环状，并且夹设于环状间隔。水和空气都属于流体，当未安装滤芯时，外界流体会顺次通过第二通道、环状间隔、第一通道、第一腔体、排出口；当安装了滤芯，则滤芯上的堵件会封住环状间隔，阻断流体从第二通道涌入，由于叶轮为第一腔体和第二腔体制造的负压，所以外界的流体会从吸污口涌入。流体穿过第二通道进入容腔相对于第二通道更大的环状间隔后，能削弱流体的流速，避免对设备产生冲击。
在优选的方案中，第二通道的数量为2个以上，并且环设于第二腔体的外围。2个以 上的第二通道能使进入环状间隔的流体产生对向反冲效果，从而削弱流体对设备内部的冲击。
在优选的方案中，排出口和第二通道的数量相同，对应于第二通道环设于第一腔体的外周，主壳体设有连通排出口和第二通道的槽体，即排出口和第二通道是成对相邻设置在主壳体上的，主壳体设有连通排出口和第二通道的槽体。槽体的作用非常大，当未安装滤芯时，外界流体会顺次通过第二通道、环状间隔、第一通道、第一腔体、排出口，由于槽体的存在，从排出口排出的流体会通过槽体再一次进入第二通道，从而避免第二通道过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。
在优选的方案中，第二通道的外端高于所述的排出口，这样从排出口排出的流体会有很大一部分逃逸至第二通道，从而避免第二通道过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。
在优选的方案中，槽体的底部到第一通道中心的距离小于排出口到第一通道中心的距离，即槽体的底部低于排出口，槽体比排出口更贴近第一腔体的中心。这样的结构使第一腔体内的流体有一部分在还未到达排出口时就从槽体中逃逸到第二通道甚至环状间隔中，从而避免第二通道过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。
在优选的方案中，隔板在第一通道的边缘设有朝向吸污口方向的环状凸起。环状凸起能将从第二通道涌入的一部分流体导向吸污口方向，从而能抵消吸污口轻微吸入的垃圾。
在优选的方案中，所有第二通道的最小截面积之和大于吸污口的最小截面积。外界的流体会优先从第二通道涌入。
在优选的方案中，第二通道至第一通道之间的距离小于吸污口至第一通道之间的距离。由于远端受到的负压较小，所以外界的流体会优先从第二通道涌入。
在优选的方案中，主壳体包括套在副壳体外周的环状部，可拆卸结构包括设置在环状部上的L形缺口，以及设置在副壳体上的限位柱，通过限位柱卡入L形缺口使副壳体和主壳体对接。
在另一种方案中，第二通道位于副壳体上，堵件贴设于第二通道的内端部。
综上所述，相较于现有技术，本发明能在忘记安装滤芯的情形下，开启设备进行作业，而不用担心垃圾会进入设备内，本发明结构有效创造了一种容错机制，对使用者友好，对设备的保护周到，无需增加电子监测设备，节省了电子检测成本。

具体实施方式
以下结合附图对本发明的实施例作进一步详细描述。
其中的附图标记为：机壳1、主壳体11、环状部111、槽体112、副壳体12、环状间隔121、第一腔体21、排出口211、第二腔体22、吸污口221、第二通道222、第一通道23、叶轮3、滤芯4、堵件41、隔板5、环状凸起51、可拆卸结构6、L形缺口61、限位柱62。
实施例一，如图1、2和图4所示：
防止因漏装滤芯导致垃圾吸入清洁设备的保护结构，包括机壳1，机壳1内设有容纳叶轮3的第一腔体21，以及容纳滤芯4的第二腔体22，第一腔体21连通有排出口211，第二腔体22连通有吸污口221，第一腔体21和第二腔体22之间通过第一通道23相连，还设有连通 第二腔体22和外界的第二通道222,第二通道222的数量为1个以上，滤芯4设有用于阻断第二通道222的堵件41。
拥有叶轮3的清洁机器人是靠叶轮3的转动在第一腔体21内产生的负压，使外界的流体通过吸污口221压入第二腔体22，垃圾则会被滤芯4阻挡，过滤后的流体则会进入第一腔体21，直至从排出口211排至外界。滤芯4和吸污口221之间的容腔是用来聚集垃圾的。
当第二腔体22中忘记装入滤芯4，在叶轮3工作时，外界的流体会通过第二通道222涌入第二腔体22，随即通过第一通道23涌入第一腔体21，直至从排出口211排回外界水体中，实施例一在漏装滤芯4状态下的工作原理如图4所示，由于叶轮3产生的负压会被第二通道222涌入的流体所填补，所以吸污口221受到的负压会大幅削弱，从而减小或避免垃圾从吸污口221吸入第二腔体22甚至垃圾涌入第一腔体21污染叶轮3。本发明能有效避免因漏装滤芯4导致垃圾吸入清洁机器人。
而传统的清洁设备是如图3所示，当忘记装滤芯4进行清洁作业时，垃圾会从吸污口221迅速而大量地涌入第二腔体22，并迅速污染第一腔体21，不仅造成第二腔体22和第一腔体21的污染，还会污染叶轮3，垃圾还会嵌入第一腔体21内的所有缝隙中。
实施例二，实施例二适用于长管状的负压清洁设备，例如手持式负压清洁器，它是在实施例一的基础上进行的优化，具体如图5至图15所示：
防止因漏装滤芯导致垃圾吸入清洁设备的保护结构，包括机壳1，机壳1内设有容纳叶轮3的第一腔体21，以及容纳滤芯4的第二腔体22，第一腔体21连通有排出口211，第二腔体22连通有吸污口221，第一腔体21和第二腔体22之间通过第一通道23相连，还设有连通第二腔体22和外界的第二通道222,第二通道222的数量为1个以上，滤芯4设有用于阻断第二通道222的堵件41。
实施例中，如图5、13、14、15所示，机壳1包括主壳体11和副壳体12，主壳体11和副壳体12之间通过可拆卸结构6对接；如图10至图12所示，第一腔体21和排出口211位于主壳体11上；如图6、7、8所示，吸污口221位于副壳体12上；如图10至图12所示，主壳体11设有隔板5，第一通道23位于隔板5上。隔板5作为第一腔体21和第二腔体22的分界。
实施例中，如图11、17、18所示，副壳体12和隔板5之间设有环状间隔121，环状间隔121连通第二通道222，堵件41为环状，并且夹设于环状间隔121。水和空气都属于流体，当未安装滤芯4时，外界流体会顺次通过第二通道222、环状间隔121、第一通道23、 第一腔体21、排出口211；当安装了滤芯4，则滤芯4上的堵件41会封住环状间隔121，阻断流体从第二通道222涌入，由于叶轮3为第一腔体21和第二腔体22制造的负压，所以外界的流体会从吸污口221涌入。流体穿过第二通道222进入容腔相对于第二通道222更大的环状间隔121后，能削弱流体的流速，避免对设备产生冲击。
实施例中，第二通道222的数量为2个以上，并且环设于第二腔体22的外围。2个以上的第二通道222能使进入环状间隔121的流体产生对向反冲效果，从而削弱流体对设备内部的冲击。为了便于观察，图16至19，以及图21和图22都是仅保留2个第二通道222和2个排出口211的简化版清洁设备结构图。
实施例三，实施例三是在实施例二的基础上进行的优化，如图5至图21所示：
在实施例二的基础上，排出口211和第二通道222的数量相同，对应于第二通道222环设于第一腔体21的外周，主壳体11设有连通排出口211和第二通道222的槽体112，即排出口211和第二通道222是成对相邻设置在主壳体11上的，主壳体11设有连通排出口211和第二通道222的槽体112。图16至图19显示了槽体112的结构，为了表达方便，槽体112、排出口211、第二通道222和第一通道23之间的位置关系请参照图20所示。槽体112的作用非常大，当未安装滤芯4时，外界流体会顺次通过第二通道222、环状间隔121、第一通道23、第一腔体21、排出口211，由于槽体112的存在，从排出口211排出的流体会通过槽体112再一次进入第二通道222，从而避免第二通道222过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。
实施例中，如图20所示，第二通道222的外端高于所述的排出口211，这样从排出口211排出的流体会有很大一部分逃逸至第二通道222，从而避免第二通道222过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。
实施例中，如图20所示，槽体112的底部到第一通道23中心的距离N小于排出口211到第一通道23中心的距离M，即槽体112的底部低于排出口211，槽体112比排出口211更贴近第一腔体21的中心。这样的结构使第一腔体21内的流体有一部分在还未到达排出口211时就从槽体112中逃逸到第二通道222甚至环状间隔121中，从而避免第二通道222过多地吸取外界新流体，最终将设备对外界流体的扰动减小到最小。如图21所示，是实施例三中较深的槽体112配合较高的第二通道222一同完成流体循环的工作示意图。
实施例中，如图16至图19所示，隔板5在第一通道23的边缘设有朝向吸污口221方向的环状凸起51。环状凸起51能将从第二通道222涌入的一部分流体导向吸污口221方向，从而能抵消吸污口221轻微吸入的垃圾。
实施例中，如图16至18所示，主壳体11包括套在副壳体12外周的环状部111。
实施例中，所有的第二通道222的最小截面积之和大于吸污口221的最小截面积。外界的流体会优先从第二通道222涌入。
实施例中，如图6所示，第二通道222至第一通道23之间的距离小于吸污口221至第一通道23之间的距离。由于远端受到的负压较小，所以外界的流体会优先从第二通道222涌入。
实施例中，如图5、14、15所示，可拆卸结构6包括设置在环状部111上的L形缺口61，以及设置在副壳体12上的限位柱62，通过限位柱62卡入L形缺口61使副壳体12和主壳体11对接。
实施例四，如图22所示：
实施例四的以下结构和实施例二一致：防止因漏装滤芯导致垃圾吸入清洁设备的保护结构，包括机壳1，机壳1内设有容纳叶轮3的第一腔体21，以及容纳滤芯4的第二腔体22，第一腔体21连通有排出口211，第二腔体22连通有吸污口221，第一腔体21和第二腔体22之间通过第一通道23相连，还设有连通第二腔体22和外界的第二通道222,第二通道222的数量为1个以上，滤芯4设有用于阻断第二通道222的堵件41。
实施例四和实施例二一致的结构还包括：机壳1包括主壳体11和副壳体12，主壳体11和副壳体12之间通过可拆卸结构6对接；如图10至图12所示，第一腔体21和排出口211位于主壳体11上；如图6、7、8所示，吸污口221位于副壳体12上；如图10至图12所示，主壳体11设有隔板5，第一通道23位于隔板5上。隔板5作为第一腔体21和第二腔体22的分界。主壳体11包括套在副壳体12外周的环状部111。
实施例中，所有的第二通道222的最小截面积之和大于吸污口221的最小截面积。外界的流体会优先从第二通道222涌入。
但是实施例四和实施例二不同之处在于：第二通道222位于副壳体12上，堵件41贴设于第二通道222的内端部。
实施例五，如图23所示:
实施例五是对主壳体11和副壳体12之间的连接方式作出和实施例三不同的结构，即主壳体11没有环状部111套在副壳体12的外周，而是主壳体11和副壳体12之间通过端部对接方式连接。
本发明的最佳实施例已阐明，由本领域普通技术人员做出的各种变化或改型都不会脱离本发明的范围。
