Description

一种清洁设备的喷水结构 技术领域
本发明涉及地面清洁技术领域，具体为一种清洁设备的喷水结构。
背景技术
地面清洁设备在家庭生活中较为常见，主要可以用来打扫家庭卫生，相比较以往的扫帚、拖把，清洁能力更强。
清洁设备在持续对地面实施清洁作业一定时间后会产生赃物，引起污渍积累，导致外表面不能保持持续的自清洁能力，清洁效率低，经分析，目前清洁效率低的原因有以下几种：1)水槽口位置及流道排布的设置：在清洁设备的喷水结构内用于清洁液体流动的流道和喷液水槽的开口位置配合设置不合理，水槽口设置在一侧，清洁液体就将会从此侧向另一侧由水泵压力的作用下依次由喷头喷出，靠近水槽口处的喷头压力将会与远离水槽口的喷头压力有较大相差，压力不均导致喷液效果不均，导致清洗液不能有效的将滚刷上的赃物清洗掉，水槽口设置在水槽一侧的三分至一处，同样也会出现靠近水槽口处的喷头压力将会与远离水槽口的喷头压力有相差，同样影响清洗滚刷上赃物的清洁效果；2)喷头的数量：当水泵规格压力确定后喷头的数量就随之确定了上限，喷头的数量设置较少时，水泵的压大就会出现喷水量比较大的情况，当喷水量大于刮水板刮水量,就会出现地板水渍残留比较多，地面清洁不彻底，喷头的数量设置过多时，虽然喷头的喷液对滚刷的表面积增加，但是也会出现由于喷头数量过多引起喷液压力不足的情况，出现喷头喷水量较小，滚刷主体表面喷到的喷力小，液体少，导致其表面的污渍不易被刮掉，基于此类原因滚刷在持续一定清洁地面的作业过程中引起污渍积累，导致外表面不能保持持续的自清洁能力，清洁效率低。
发明内容

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在本发明的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“顶”、“底”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
请参阅图1-5，本发明提供一种技术方案：一种清洁设备的喷水结构，包括：
喷水机构1，喷水机构1可拆卸连接在清洁盖板5下方，如图1所示，清洁盖板5包覆在喷水机构1、清洁部件6的外侧，喷水机构1下侧设有用于对清洁部件6上污渍刮除的刮板7，刮板7贴附在清洁部件6的表面上，随着清洁部件6的转动将清洁部件6表面污渍刮下，所述喷水机构1包括一个盖板3和位于盖板3下部的一个底板4；
在所述盖板3的下表面开设流道8，在所述底板4的上表面内凹形成水槽 9，且在所述水槽9内设有横向等距离排列有用于对清洁部件6冲洗的喷头10，所述水槽9的中部设置有与流道8末端连通的水槽口，所述流道8的初始端连接供水设备；
流道8设置为弯折状，如图3所示。
供水设备包括水泵2、出水管，所述水泵2的出水口通过出水管与流道8的初始端连通，流道8的初始端与出水管连接处设有密封环；
喷头10的结构为倒置喇叭口形状；
所述盖板3、底板4密封组合后内部形成保压室，所述保压室内水压大于喷头10中水表面张力，喷头10向外界喷出密集的柱状清洁液体。
清洁设备运行过程中，通过水泵2的进水管与清水箱连接，水泵2的出水端通过出水管与喷水机构1的流道8初始端连接。
实施例一：
水槽9纵向的深度设置为2.5毫米。
水槽9内设有30个横向间隔排列的喷头10。喷头10的出水口的孔径为0.5毫米。且相邻喷头10轴线之间的距离为7毫米。
实施例二：
水槽9纵向的深度设置为3毫米。
水槽9内设有20个横向间隔排列的喷头10。喷头10的出水口的孔径为0.54毫米。且相邻喷头10轴线之间的距离为7毫米。
经过验证同为水槽口处于中心处的情况下，设定与上述实施例的对照组：
水泵2压力固定时，喷头10数量设置16个，喷头10孔径设至0.8毫米，相邻喷头10间隔设置12毫米时。
经过对比分析，对照组在经过5平方米的持续清洁过程中滚刷表面开始出现赃物现象，直至10平方米自清洁能力开始下降，滚刷出现不易清洗的赃物。
本方案两个实施例经过5平方米的持续清洁过程中均未出现或极少出现赃物，直至清洁至10平方米开始出现赃物现象，但仍保持一定的自清洁能力。
通过本方案的组合有效的提升了清洁设备在持续一定清洁地面的作业过程中，保持持续的自清洁能力，提高清洁效率的效果。
工作原理：清洁设备运行过程中，通过水泵2的进水管与清水箱连接，水泵2的出水端通过出水管与喷水机构1的进水端(即流道8的初始端)连接，进水端与喷水机构1连接处设有密封环，保证喷水机构1的密封性。喷水机构1由数颗金属螺丝锁固在清洁盖板5上。在喷水机构1下方设有用于对清洁部件6上污渍刮除的刮板7。刮板7前端设置清洁部件6的滚刷，刮板7与滚刷为过盈配合，以便于刮除滚刷表面的污垢及喷液。刮板7与清洁盖板5和滚刷的组合使其内部形成了一定的密封空间。
当清水箱的清洗液通过水泵2的压力向喷水机构1内部注入，清洗液在由盖板3和底板4密封组合形成的保压室内部的流道8转折流至水槽9中心处。由水槽9中心处分别向两边依次流入水槽9内并由喷头10喷出清洗液。
因其保压室内的水压可以维持在一定的范围内，且每个喷头10之间的间距、形状及孔径的合理设置及配合使其能在内部压力下向外界持续喷出比较密集的清洗液。经过设置在喷水机构1下方的刮板7配合均匀喷出的清洗液有效的对滚动的滚刷上的污渍进行刮除。
在保证水压不减弱的情况下，以最多的喷头10数量，及最大的喷射液体与滚刷的接触面积来保持滚刷表面的清洁。从而保持持续的自清洁能力，达到提高效率的功效。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点,对于本领域技术人员而言，显然本发明不限于上述示范性实施例的细节，而且在不背离本发明的精神或基本特征的情况下，能够以其他的具体形式实现本发明；因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限 制性的，本发明的范围由所附权利要求而不是上述说明限定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本发明内，不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
