本申请的实施方式
为了详细说明本申请的技术内容、构造特征、实现的效果,以下结合实施方式并配合附图详予说明。
如图1至图10所示,本申请一些实施例公开了一种基站,用于对清洁设备进行护理,例如对清洁设备进行清洗,对配备有清水箱的清洁设备进行补水,及/或,对配备有污水箱的清洁设备进行污水排出。其中,清洁设备可以包括能够自主移动的清洁机器人,也可以包括能够被用户手持驱动的手持式清洁设备,例如手持清洗机等。
基站可以包括基站主体210和水箱组件102,在一些实施例中,基站主体210上可以设有清洗系统X。清洗系统X可以用于输送基站对清洁机器人的拖擦件进行清洗所需的清水,在一些实施例中,清洗系统可以用于吸取基站对清洁机器人的拖擦件进行清洗后所产生的污水。
在一些实施例中,如图3所示,水箱组件102可以安装于基站主体210的基站支架101上。
水箱组件102包括箱体104,箱体104内形成有清水腔106。在一些实施例中,清洗系统X可以与清水腔106连通,以使得清水腔106可以向清洗系统X提供清水。在其他一些实施例中,在配备有清水箱的清洁设备对接于基站的状态下,基站的清水腔106可与清洁设备的清水箱连通,以使得清水腔106内的清水能够输送至清洁设备。
请参阅图4至图6及图10,清水腔106通过进水通道107与外部管路152连通,外部管路152能够向清水腔106内输送清水。进水通道107设置有单向阀114,单向阀114具有第一状态和第二状态,单向阀114处于第一状态时允许外部管路152的水朝向清水腔106流动,单向阀114处于第二状态时限制水从进水通道107向外流出。
本申请实施例的水箱组件102中,在外部管路152向清水腔106输送清水时,单向阀114处于第一状态以允许外部管路152的水输送至清水腔106。 在停止向清水腔106输送清水时,单向阀114处于第二状态以限制进水通道107的水向外流出,能够在将外部管路152移除的情况下,阻碍进水通道107的清水向外流出。
在一些实施例中,第一状态可以为打开状态,单向阀114可以在进水通道107朝向清水腔106所在方向流动的水流的压力作用下,而处于打开状态以允许外部管路152的水输送至清水腔106。
第二状态可以为闭合状态,或者说微开状态(允许小缝隙存在)。当清水腔106内存在液体,且外部管路152停止向清水腔106输送清水时,清水腔106内的水压大于进水通道107处的水压,清水腔106内的水压可以反向给单向阀114施加阻碍其进一步打开的阻力,因此单向阀114可以处于闭合或接近闭合的状态,进而阻碍清水腔106内的清水向外流出。
在本申请实施例中的单向阀114的出水端可以包括弹性结构,弹性结构使得出水端的开口能够在预设水压或气压的作用下而闭合或接近闭合。示例性的,单向阀114可以为鸭嘴阀。
需要说明的是,本申请实施例中所描述的“向外流出”是指水从清水腔106沿进水通道107向外部管路152所在方向流动至清洁基站的外部。
可以理解的是,进水通道107可以形成在箱体104上,也可以形成在与箱体104连接的管道上,或者部分形成在箱体104上,部分形成在与箱体104连接的管道上。
在一些实施例中,如图5和图6所示,单向阀114可以为鸭嘴阀,鸭嘴阀包括可伸缩的开口以允许外部管路152的水通过,以及限制清水腔106的水向外流出。当外部管路152的水朝向清水腔106流动时,鸭嘴阀的开口在朝向清水腔106流动的水的压力作用下打开以使水流入清水腔106;当外部管路152的水停止向清水腔106流动时,鸭嘴阀的开口由于自身的可伸缩特性而相应地产生收缩至接近闭合的状态,进而可限制水向外流出,特别的,清水腔106内的液体也可反向给鸭嘴阀施加阻碍其进一步打开的阻力,而使得鸭嘴阀更可靠地限制水向外流出。示例性的,鸭嘴阀在常态下可以处于能够限制水回流的微开状态(第二状态),当外部管路152的水经由进水通道107朝向清水腔106流动时,在水压的作用下,鸭嘴阀从微开状态变化为打开状态(第一状态),在停止向清水腔106供水时,鸭嘴阀可从打开状态恢复为微开状态。当然,在其他一些实施例中,鸭嘴阀在常态下可以处于闭合状态。
需要说明的是,本申请实施例中所描述的微开状态是指鸭嘴阀在常态下,开口处具有预设的微小间隙。
本申请实施例中,单向阀114还可以为弹簧式单向阀,当外部管路152的清水朝向清水腔106流动时,弹簧式单向阀在朝向清水腔106流动的水的压力作用下打开(第一状态)以允许水输送至清水腔106,当外部管路152的水停止向清水腔106流动时,弹簧式单向阀在自身弹簧力的作用下关闭(第二状态)以限制清水向外流出。
当然,本申请实施例的单向阀114可以但不限于上述鸭嘴阀和弹簧式单向阀,只要能够在外部管路152的清水向清水腔106输送时处于允许清水通过的第一状态且在水停止向清水腔106输送时变化为限制水向外流出的第二状态即可。
如图4和图5所示,水箱组件102还可以包括转接座120,转接座120用于可拆卸地连接于箱体104,且将进水通道107与外部管路152连通,从而便于将外部管路152的水输送至清水腔106。借由转接座120的设置,方便进水通道107与外部管路152的连接,当将转接座120从箱体104上拆开时,设于进水通道107的单向阀114能够防止进水通道107中的水向外流出。
在一些实施例中,如图5和图6所示,箱体104的底部可以凸设有进水管道结构121,进水管道结构121包括进水口123和出水口125,进水通道107的水依次经过进水口123和出水口125进入至清水腔106内。
具体而言,本申请实施例对进水管道结构121的具体形式不作限制,比如,进水管道结构121可以自箱体104的底部朝向清水腔106向上凸设;进水管道结构121也可以自箱体104的底部朝向与清水腔106背离的方向凸设;当然,进水管道结构121还可以既包括朝向清水腔106向上凸设的第一部分,也包括朝向与清水腔106背离的方向凸设的第二部分,且第一部分和第二部分连通,等等。
水箱组件102还包括进水连接头109,进水连接头109一端连接有用于与转接座120连接的第一进水管道112,进水连接头109的另一端连接至进水口123处,且与清水腔106连通,第一进水管道112内部形成第一进水通道113,进水连接头109内部形成第二进水通道111,进水通道107包括第一进水通道113与第二进水通道111。
具体而言,第一进水管道112通过转接座120与外部管路152连通,外部管路的水经由转接座120内部的通道、第一进水通道113、第二进水通道111输送至清水腔106,当将转接座120从箱体104拆开时,设置在进水通道107的单向阀114能够防止清水从第一进水管道112向外流出。
当然,进水通道107并不局限于上述具体形式,只要能够实现与外部管 路152连通以向清水腔106输送清水的作用即可。比如,第一进水管道112可以只包括单个水管,也可以由至少两个水管连接形成;箱体2也可以通过进水连接头109直接连接至转接座120的管道或者直接与外部管路152连接,等等。
需要注意的是,进水连接头109可以连接在箱体104的进水口123处并通过进水口25与清水腔106连通;进水连接头109也可以直接从箱体104的进水口123穿入清水腔106;又或者箱体104上设有向沿背离清水腔106所在方向凸出的进水管道结构121,进水口123形成在进水管道结构121远离清水腔106的一端,进水管道结构121与清水腔106连通,进水连接头109与进水管道结构121连接并通过进水管道结构121与清水腔106连通,等等,本申请实施例对此不作限制。
在一些实施例中,单向阀114可以为鸭嘴阀,鸭嘴阀可以夹设在进水口123与进水连接头109之间以密封进水口123与进水连接头109的连接位置。将鸭嘴阀夹设在进水口123与进水连接头109之间除了能够阻碍进水口123处的水回流,还能够起到将进水口123和进水连接头109之间密封的作用,无需另外设置密封件对进水口123和进水连接头109的连接处进行密封,能够简化水箱组件102的结构并降低成本。
示例性地,如图6所示,进水连接头109可以通过紧固件127装配至箱体104,进水连接头109与箱体104在装配状态下,两者之间形成供鸭嘴阀安装的安装间隙(图中未标注),鸭嘴阀被夹设在安装间隙处,以用于阻止进水连接头109相对箱体104晃动,从而能够实现进水连接头109与箱体104的密封连接,且当鸭嘴阀被漏安装时,由于安装间隙的存在,在将进水连接头109与箱体104通过紧固件127装配在一起时,进水连接头109容易产生晃动,从而能够反检出鸭嘴阀是否安装至进水口123处。
具体地,鸭嘴阀的进水端的外周可以向外凸设有搭接部116,进水口123处设置有连接部118,搭接部116搭接在连接部118,搭接部116夹设在进水连接头109和进水口123之间。通过在鸭嘴阀的外周设置搭接部116,方便将鸭嘴阀夹设在进水连接头109和进水口123之间,有利于提高进水连接头109与进水口123之间的密封性。
如图6所示,为了进一步提高进水连接头109和进水口123的密封性,以及鸭嘴阀的安装可靠性,搭接部116可以凹设有沟槽117,连接部118包括沿背离清水腔106所在方向凸出的凸部119,沟槽117可以套设在凸部119上。
当然,上述单向阀114不限于鸭嘴阀,也不限于设置进水连接头109和 进水口123之间,只要设于进水通道107,且能够实现在将转接座120从箱体104上拆下时,能够限制进水通道107的水向外流出即可。
在一些实施例中,进水连接头109可以设置为透明或半透明件,从而可以进一步方便查看鸭嘴阀是否安装,或者,也可以将第一进水管道112设置为透明或半透明件以方便查看鸭嘴阀是否安装。
当然,进水连接头109和第一进水管道112可以均设置为透明或半透明件,也可以仅设置其一为透明或半透明件。
请参阅图5和图7,可以在清水腔106内设置有浮球阀129,进水管道结构121的出水口125处可以设置可浮动的堵头结构130;浮球阀129被配置为根据清水腔106内的水位高低上下运动进而向下推动或者向上释放堵头结构130,当水位上升至预设高度时,堵头结构130向下移动至堵住出水口125;堵头结构130包括安装体131、第一弹性体132和第二弹性体133,第一弹性体132和第二弹性体133分别安装在安装体131的高度方向的两端。具体地,当清水腔106内的水位较低时,进水通道107朝向清水腔106流动的清水可以正常经由进水口123和出水口125流入清水腔106,堵头结构130不会堵住出水口125。随着水位的上升,浮球阀129在清水的浮力作用下产生运动,当清水腔106的水位达到预设高度时,堵头结构130被浮球阀129向下推动至出水口125并将出水口125堵住,从而能够防止清水腔106内水位过高。而将堵头结构130设置为高度方向上的两端分别安装有第一弹性体132和第二弹性体133,第一弹性体132和第二弹性体133的任一个均可将出水口125堵住,能够防止堵头结构130装反时对出水口125进行封堵的密封性不足。
更进一步的,第一弹性体132和第二弹性体133的结构形状可以相同,以可以使用同一模具,降低加工成本。
另外,申请人经过创造性地劳动发现,清洁基站的污水腔当具有排污功能时,若通过水泵将污水腔内的污水排出,由于污水中杂质较多,极易使得杂质堵塞水泵的叶轮,从而降低排污可靠性。另外,当污水需要经过水泵时,在水泵之前需要安装过滤网,以降低杂质卡滞水泵的风险,但是该种情况下,由于污水杂质一般较多,使得用户需要定期清理、维护或更换该过滤网,并且过滤网较易滋生细菌发臭,导致用户体验稍差。为解决上述特定的技术问题,本申请另一实施例提供一种水箱组件,如图1至图5、图8和图9所示,本申请还提供了另一种基站,用于对清洁设备进行护理,基站包括基站主体210和水箱组件103,基站主体210上设有清洗系统,水箱组件103包括箱体105,箱体105内形成有污水腔135以接收清洗系统产生的污水。箱体105设 有与污水腔135连通的进水通道108和排污通道136;污水腔135被配置为能够接收外部气源所施加的负压,以使外部污水能够经过进水通道108吸入污水腔135内,以及,能够接收外部气源所施加的正压,以使污水腔135内的污水能够通过排污通道136排出。
其中,进水通道108设有单向阀115,当污水腔135处于正压状态时,单向阀115处于关闭状态,当污水腔135处于负压状态时,单向阀115处于打开状态。
当外部气源向污水腔135施加负压时,单向阀115处于打开状态,使得污水可以经过进水通道108被吸入污水腔135内;当污水腔135需要将污水排出时,外部气源向污水腔135施加正压,使得污水可以通过排污通道136排出,单向阀115处于关闭状态,可以阻碍污水腔135内的气体从进水通道108的单向阀115处排出,以使得污水腔135内的水能够在正压作用下从排污通道排出。
另外,单向阀115的设置还可以阻碍污水在正压作用下从进水通道108向外流出。需要说明的是,本申请实施例中的“向外流出”是指污水从污水腔135沿进水通道108流出至清洗系统。
可以理解的是,为了使外部气源向污水腔135施加正压或负压,可以在箱体105上开设气孔,气孔通过气管与外部气源连接,外部气源可以包括但不限于气泵。当外部气源为气泵时,气泵的数量也不限于一个。在一些实施例中,气泵的数量可以为两个,其中一个气泵可以用于为污水腔135施加正压,另一个气泵可以用于为污水腔135施加负压。
在本申请实施例中,单向阀115可以为鸭嘴阀,较优的,如图8所示,鸭嘴阀可以沿竖向悬挂于箱体内,鸭嘴阀竖置的方式,污水中的杂质颗粒可以在重力的作用下落下,可以有效降低杂质颗粒卡滞于鸭嘴阀的开口处而堵塞或损坏鸭嘴阀的风险。
具体地,水箱组件103安装在基站主体210上时,箱体105上的进水通道108连接至清洗系统的输水管路以使污水腔135接收清洗系统产生的污水。
可以理解的是,进水通道108可以形成在箱体105上,也可以形成在与箱体105连接的管道上,或者部分形成在箱体105上,部分形成在与箱体105连接的管道上。
如图8和图9所示,单向阀115可以为鸭嘴阀,当外部气源向污水腔135施加负压时,由于外部气压大于污水腔135的内部气压,鸭嘴阀的可伸缩开口打开以使污水能够被吸入污水腔135,当外部气压向污水腔135施加负压时, 由于外部气压小于污水腔135内气压,鸭嘴阀的可伸缩开口闭合从而限制污水从进水通道108向外流出。具体地,鸭嘴阀常态下可以处于通气但不通水的微开状态。当然,本申请实施例中的单向阀115不限于为鸭嘴阀,只要能够在污水腔135处于负压状态时为打开状态,在污水腔135处于正压状态时为关闭状态即可。
具体地,单向阀115可以包括第一鸭嘴阀137和第二鸭嘴阀142,第一鸭嘴阀137和第二鸭嘴阀142沿进水方向依次布置。通过在进水通道108设置第一鸭嘴阀137和第二鸭嘴阀142,能够防止第一鸭嘴阀137和第二鸭嘴阀142之一者损坏时限制污水从进水通道108向外流出的作用失效。此外,当需要排水时向污水腔135施加正压且排污通道136被堵住时,污水腔135内的正压将会很大,设置在进水管道结构122的第一鸭嘴阀137和第二鸭嘴阀142之间的密封空间能够容纳空气,此时,第一鸭嘴阀137和第二鸭嘴阀142之间的密封空间内的空气能够与污水腔135内的正压平衡,进而有利于阻碍第二鸭嘴阀142上翻。
将单向阀115设置为鸭嘴阀时,由于鸭嘴阀为呈悬置的柔性状态,当需要排水向污水腔135施加正压时,若排污通道136被堵住,污水腔135内的正压将会很大,在正压的作用下,有可能导致鸭嘴阀上翻。为了降低鸭嘴阀上翻的风险,可以在箱体105的进水通道108处设置供单向阀115安装的安装部149,安装部149形成有供水流通过的进水通路,鸭嘴阀套设于安装部149外侧。通过将鸭嘴阀套设在安装部149的外侧,当外部气源对污水腔135施加正压时,由于安装部149的止抵作用,有利于阻碍鸭嘴阀上翻。而且在进水通道108处设置安装部149,还可以方便对鸭嘴阀的安装。
需要注意的是,鸭嘴阀包括进水端145/146和出水端147/148,进水端145/146呈直筒状,出水端147/148的横截面积沿靠近进水端145/146的一端向远离进水端145/146的一端逐渐减小,安装部149延伸至进水端145/146与出水端147/148的连接处,能够防止安装部149将鸭嘴阀的出水端147/148撑开,导致鸭嘴阀的出水端147/148的开口始终打开而失去阻碍污水通过进水通道108向外流出的作用。
当然,本申请实施例中,鸭嘴阀可以设置在进水通道108的不同位置,只要能够限制污水从进水通道108向外流出即可。
如图8所示,单向阀115包括第一鸭嘴阀137,箱体105可拆卸地连接有进水接头110,进水接头110靠近污水腔135的一端形成安装部149,第一鸭嘴阀137的进水端145套设于进水接头110外侧。通过将第一鸭嘴阀137的 进水端145套设在进水接头110外侧,使得第一鸭嘴阀137的进水端145能够被进水接头110止抵,当外部气源对污水腔135施加正压时,由于进水接头110的止抵作用,能够有效阻碍第一鸭嘴阀137上翻。
在一些实施例中,第一鸭嘴阀137的进水端145的外周向外凸设有第一搭接部138,箱体105的进水口124处设置有第一连接部140,第一搭接部138搭接在第一连接部140,第一搭接部138夹设在进水接头110和进水口124之间,能够实现进水接头110和进水口124的密封连接,无需另外设置密封件以密封进水接头110和进水口124,从而能够简化水箱组件103的结构并降低成本。
在一些实施例中,第一搭接部138凹设有第一沟槽139,第一连接部140包括沿背离污水腔135所在方向凸出的第一凸部141,第一沟槽139套设在第一凸部141上,能够进一步提高进水接头110和进水口124的密封性。
为了提高限制污水从进水通道108流出的稳定性,单向阀115还包括第二鸭嘴阀142,箱体105具有进水管道结构122,进水管道结构122的一端与进水接头110连通,进水管道结构122的另一端朝污水腔135内部凸出,进水管道结构122的另一端具有出水口126;第二鸭嘴阀142的进水端146设于出水口126处,进水管道结构122内设有衬套150,衬套150形成安装部149,第二鸭嘴阀142的进水端146套设于衬套150外侧。
通过在进水通道108设置第一鸭嘴阀137和第二鸭嘴阀142,能够防止第一鸭嘴阀137和第二鸭嘴阀142之一者损坏时限制污水从进水通道108向外流出的作用失效。同时,通过将第二鸭嘴阀142的进水端146套设在衬套150上的安装部149外侧,使得第二鸭嘴阀142的进水端146被安装部149止抵,当外部气源对污水腔135施加正压时,由于安装部149的止抵作用,有利于阻碍第二鸭嘴阀142上翻。此外,当需要排水时向污水腔135施加正压时,若排污通道136被堵住,污水腔135内的正压将会很大,设置在进水管道结构122的第一鸭嘴阀137和第二鸭嘴阀142之间的密封空间能够容纳空气,此时,第一鸭嘴阀137和第二鸭嘴阀142之间的密封空间内的空气能够与污水腔135内的正压进行平衡,从而可以进一步阻碍第二鸭嘴阀142上翻。
在一些实施例中,第二鸭嘴阀142的进水端146的外周可以向外凸设有第二搭接部143;衬套150形成有压接部151;出水口126的内侧设置有第二连接部144;第二搭接部143搭接在第二连接部144,第二搭接部143被压接在压接部151与第二连接部144之间,实现出水口126与第二鸭嘴阀142之间的密封连接的同时,还能够使第二鸭嘴阀142与进水管道结构122之间的 连接更加稳固。
在一些实施例中,第一鸭嘴阀137的进水端146的外周可以向外凸设有第一搭接部138,衬套150远离第二鸭嘴阀142的一端形成第一连接部140,第一搭接部138被夹设在进水管道结构122的进水口124、衬套150和进水接头110之间,能够起到进水口124和进水接头110之间的密封作用,无需另外设置密封件对进水口124和进水接头110进行密封,能够简化水箱组件103的结构并降低成本。
当然,第一连接部140并不局限于设置在衬套150上,比如,第一连接部140也可以直接形成在进水管道结构122靠近进水接头110的一端。
为了提高进水接头110与箱体105连接的稳固性,单向阀115设为鸭嘴阀,通过紧固件128将进水接头110装配至箱体105,进水接头110与箱体105在装配状态下,两者之间形成供鸭嘴阀安装的安装间隙,鸭嘴阀被夹设在安装间隙处,以用于阻止进水接头110相对箱体105晃动,进而能够实现进水接头110与箱体105的密封连接,且当鸭嘴阀被漏安装时,由于安装间隙的存在,在将进水接头110与箱体105通过紧固件128装配在一起时,进水接头110容易产生晃动,从而能够反检出鸭嘴阀是否安装。
在一些实施例中,进水接头110可以为透明或半透明件,从而方便查看鸭嘴阀是否安装。
如图3至图9所示,在具体的示例中,箱体104形成有清水腔106和安装腔134,安装腔134内安装有作为污水箱的箱体105。箱体104上形成有与安装腔134连通的进水接口,进水通道108连接在进水接口处,在箱体104安装至基站主体210上时,进水接口对接至清洗系统的污水接口;排污通道136设置在箱体105的下部。需要注意的是,水箱组件102并不局限于该具体示例中的形式,比如,箱体104可以不设置安装腔,箱体105可以直接安装在基站主体210上,或者箱体104和箱体105可以为同一箱体,即同一箱体上既形成有清水腔106,又形成有污水腔135。
基站可以包括用于对清洁机器人进行护理的清洗系统,示例性的,可以通过清洗系统对清洁机器人的拖擦件进行清洁,基站会配置清水箱和污水箱,清水箱内的水用于提供给清洁系统,污水箱用于收集清洁系统所产生的污水;另外,清水箱可以连通外界,以使得外界的清水输入至清水箱,污水箱连通外界,以使得污水箱内的污水可以排向外界。
然而,在相关技术中,对于水箱内的水的抽水操作通常通过气源抽负压实现,而排水操作通常通过水泵实现,如此设置,容易导致当水箱需要抽排 水功能时,需要配备气源和水泵,结构复杂,且当水质较差,杂质较多时,水中的杂质也容易对水泵的叶轮造成损坏,甚至使得叶轮产生卡滞。
本申请还提出一种抽排水系统,参见图11a和图11b,包括:
第一水箱201,第一水箱201形成有储水腔C,第一水箱201具有通气口202,通气口202与储水腔C连通;
气源系统,气源系统与通气口202连通;
当气源系统处于第一状态时,储水腔内的气体依次经过通气口202、气源系统排出,以使储水腔C处于负压状态,进而使得储水腔C能够吸入液体;当气源系统处于第二状态时,气源系统通过通气口202向储水腔C内输送气体,以使储水腔处于正压状态,进而使得储水腔C内的液体能够排出。本申请所提出的抽排水系统可进行自动吸水和排水,其中第一水箱201的储水腔C用于储水(例如可以储存清水或污水)。
需要说明的是,本申请实施例所所描述的液体可以是纯净的液体,也可以是混合有固体颗粒、毛发、碎屑等杂质的混合液体。
以图1所示为例,第一水箱201的通气口202用于出气或进气,气源系统与通气口202连通,进而通过通气口202从储水腔C抽气或向储水腔注气。进一步的,第一水箱201还具有进水口203和排水口(图中未示出),进水口203和排水口均与储水腔连通。抽排水系统的抽排水原理为:气源系统处于第一状态时,储水腔C内的气体依次经过通气口202、气源系统排出,从而使储水腔C处于负压状态,第一水箱201从进水口203处吸水至储水腔C内;气源系统处于第二状态时,气源系统通过通气口202向储水腔C内输送气体,从而使储水腔C处于正压状态,第一水箱201从排水口处将储水腔C的水排出。
当本申请实施例的抽排水系统的储水腔用于储存污水时可实现污水的自动收集,以及污水收集后的自动排放,无需人为进行污水清理操作,使用方便,智能化程度高,有助于提升用户使用体验。
而当本申请实施例的抽排水系统的储水腔用于储存清水时,可以通过气源系统实现从外部水源抽吸清水至储水腔,还可以通过气源系统实现将储水腔内的清水排出。示例性的,当抽排水系统应用于清洁基站时,可以将清水排向(或者说喷向)清洁基站上用于清洁机器人的拖擦件的清洗区。其中,气源系统处于第一状态或第二状态,其实现形式根据气源系统的实际结构组成设置。气源系统的结构组成可为多种,具体内容在后续实施例中进行说明。
在一些实施例中,参见图11a和图11b,气源系统可以包括:
气泵;
换向阀205,与气泵和通气口202分别连通,换向阀205包括换向元件,换向元件能够在第一位置和第二位置运动;
当换向元件处于第一位置时,储水腔内的气体依次经过通气口202、换向阀205及气泵排出,以使储水腔处于负压状态;
当换向元件处于第二位置时,外部气体依次经过换向阀205、气泵和通气口202排向储水腔内,以使储水腔处于正压状态。
另外,当本申请的抽排水系统应用于污水抽排时,可以使得污水抽排不经过泵体等动力装置,实现“水不过泵”,可以有效保护泵体不易被污水中杂质的损坏和卡滞,有利于提高泵体的使用寿命。由于污水不经过泵体,因此,因此也无需在泵体之前安装过滤网,进而也不存在需要用户维护过滤网的问题,有利于提高用户体验。
需要说明的是,图11a和图11b中的换向阀205的具体结构和具体固定方式和固定位置仅为示例,本申请并不以此为限。
气源系统由气泵和换向阀205组成,气泵的作用在于提供驱动气源,换向阀205设于气泵与第一水箱201之间,与气泵和通气口202分别连通,其作用在于进行气路切换。
通过气泵和换向阀205实现正负压切换,相较于活塞等正负压切换的方式,可实现气量调节,有利于调节气泵的进出气量,例如,当进气量大于出气量时,可以有利于污水箱内的液体排出,排尽。而相较于采用两个气泵的方式实现正负压切换,有利于节约成本,并且由于换向阀205的使用寿命较长于气泵,从而可以有效延长整个气源系统的使用寿命。
气泵具有进气口和出气口,气泵的进气口、出气口以及第一水箱201的通气口202,可连通换向阀205上的不同气孔,换向阀205具体通过其换向元件在第一位置和第二位置运动。换向元件上构造有可对接气孔并使不同气孔连通的气体通道,也即,换向元件运动至第一位置或第二位置时,换向阀205的不同气孔对应连通,进而使得气泵的进气口与通气口202连通,或者气泵的出气口与通气口202连通。
需要说明的是,通气口202的数量并不限于图示中的一个,在一些实施例中,通气口202的数量也可以为两个,其中一个通气口202将气泵的气体输送至储水腔内,另一个通气口202用于供储水腔内的气体排出。
当换向元件处于第一位置时,储水腔内的气体依次经过通气口202、换向阀205及气泵排出,以使储水腔处于负压状态;当换向元件处于第二位置时, 外部气体依次经过换向阀205、气泵和通气口202排向储水腔内,以使储水腔处于正压状态。换向元件可以是转动件、平动件等,并且,换向元件可通过驱动元件的驱动进行运动,示例性的,驱动元件可以包括电机,电机可以通过传动机构传动换向元件运动,传动机构的结构形式根据实际情况设置,或者电机直接带动换向元件运动。
除上述实现方式以外,气源系统还可为其它。比如,气源系统包括正反转气泵,正反转气泵与第一水箱201的通气口202连通。正反转气泵正转时,即气源系统处于第一状态,储水腔内的气体依次经过通气口202、正反转气泵排出,以使储水腔处于负压状态;正反转气泵反转时,即气源系统处于第二状态,正反转气泵通过通气口202向储水腔内输送气体,以使储水腔处于正压状态。还比如,气源系统包括气缸式结构,与第一水箱201的通气口202连通,通过前进后退的动作以实现储水腔的正负压状态切换。此仅为示例性的,并非限制性的,包括但不仅限于此。
在一些实施例中,参见图11a和图11b,第一水箱201包括:
第一箱体206,形成有容纳腔207;
第二箱体208,设于容纳腔207内,第二箱体208内用于容纳液体(清水或污水);
换向阀205设于容纳腔207内。
第一水箱201采用“箱中箱”的结构形式,具体可以包括第一箱体206和第二箱体208,第二箱体208位于第一箱体206中,其中,第一水箱201的储水腔以及通气口202均形成于第二箱体208,通过第二箱体208容纳液体。当储水腔用于容纳污水时,第二箱体208吸入的污水还可自动排出至外界,故第二箱体208的容积可不用过大,第二箱体208采用小体积箱体。与此同时,换向阀205可设于第一箱体206中除第二箱体208占用空间以外的空间,并在第一箱体206中进行气管设置,充分利用水箱空间,结构不外露,防尘且美观。可选地,第一箱体206采用ABS(丙烯腈/丁二烯/苯乙烯共聚物板)材料制成,美观且耐磨性好。第二箱体208由于需要容纳污水,污水的成分复杂,可能在一些化学反应下,会容易腐蚀第二箱体208的箱壁,因此,本申请实施例所提供的第二箱体208可以采用PP(聚丙烯)材料制成,使得其耐腐蚀性较好。
另外,储水腔C可以连接有进水通道M和出水通道N;在进水通道M处设有第一控制件,在出水通道N处设有第二控制件,第一控制件用于在气源系统处于第一状态时打开,以及在气源系统处于第二状态时关闭;第二控制 件用于在气源系统处于第一状态时关闭,以及在气源系统处于第二状态时打开。
在一些实施例中,第一控制件可以为单向阀或截止阀;在一些实施例中,第二控制件可以为单向阀或截止阀。示例性的,如图11b所示,第一控制件可以为单向阀(具体可以为鸭嘴阀M1),第一控制件可以设于进水通道M的进水口203处。鸭嘴阀具有单向受压导通的功能,进水通道M处的鸭嘴阀M1的导通方向与进水通道M的进水方向一致,当储水腔C需要排水时,气源系统给储水腔C内注气,施加正压。鸭嘴阀M1在储水腔C内的气压作用下处于关闭状态,保证气压将储水腔C内的液体推向出水通道N处排出。类似的,第二控制件也可以为设于出水通道N的鸭嘴阀,当储水腔C需要抽水时,气源系统给储水腔C内抽负压,出水通道N处的鸭嘴阀在外部气压的作用下处于关闭状态,储水腔C内的气体被气源系统抽走而处于负压状态,使得外部液体能够通过进水通道M被抽入储水腔C内。
当然,在其他一些实施例中,第一控制件可以设于进水通道M的其他任意位置处,第二控制件可以设于出水通道N的其他任意位置处。
在其他一些实施例中,该抽排水系统可以包括柔性进水管(图中未示出),柔性进水管内形成上述的进水通道M,第一控制件用于控制柔性进水管沿径向收缩或舒张,以打开或截断进水通道M。类似的,抽排水系统可以包括柔性出水管,柔性出水管内可以形成出水通道N,第二控制件用于控制柔性出水管沿径向收缩或舒张,以打开或截断出水通道N。示例性的,柔性进水管和柔性出水管可以为硅胶管,第一控制件和第二控制件可以为能够沿柔性进水管和柔性出水管的径向方向夹持或挤压柔性进水管和柔性出水管的动力元件,从而可以打开或截段进水通道M和出水通道N。第一控制件和第二控制件的具体结构可以根据实际需要进行具体设计,本申请实施例不做限定。
如图11c~图11e所示,第一水箱201内可以设有过滤件204,过滤件204对应通气口设置,过滤件204用于阻碍固态物质进入通气口202,并允许气体从过滤件204进入通气口202(如图11e所示,虚线箭头为气体从储水腔C进入通气口202的流动路径)。
示例性的,过滤件204可以固定于第一水箱201内,并且,第一水箱201的边缘可以与第一水箱201的壳体接触,甚至抵接,以使得储水腔C内的气体基本先经过过滤件204后才能进入通气口202内,尽可能地将固态物质阻挡在过滤件204之前,降低固态物质进入通气口202,进而进入气源系统而损坏气源系统的风险。
过滤件204可以为过滤网,或者其他能够供气体通过,但能够阻挡固态物质通过的过滤装置。需要说明的是,在过滤网上通孔的数量一定的情况下,过滤网的孔径越小,其阻碍固态物质的能力越强,但是其通气效果越差;而过滤网的孔径越大,其阻碍固态物质的能力越差,但是其通气效果越好。本领域技术人员在具体设计时,可以根据实际情况进行选择,本申请实施例不做限定。
本申请还提出一种基站,包括:基站主体210,以及如前述实施例记载的抽排水系统;其中,第一水箱201安装于基站主体210。该抽排水系统的具体结构可以参照上述实施例,由于本基站采用了上述实施例的技术方案,因此至少具有上述实施例的技术方案所带来的全部技术效果,在此不再一一赘述。
在其他一些实施例中,气泵和换向阀205均设于基站主体210,基站主体210设有至少一个接口;
通气口202通过接口与换向阀205连通。
在基站主体210上,接口与换向阀205连通,换向阀与气泵连接,即换向阀通过不同的气孔对应连接气泵的进气口和出气口,且换向阀设有排气气孔连通大气环境。气泵工作时,气体的流动方向通过换向阀205切换控制,气体依次经基站主体210的接口、换向阀205、气泵的进气口流入气泵,并自气泵的出气口流至换向阀205,并经换向阀205流出;或者,气体自换向阀205进入,经气泵的进气口流入气泵,并依次经气泵的出气口、换向阀205、基站主体210的接口流出。基站主体210安装第一水箱201时,通气口202通过接口与换向阀205连通。基站主体210通过换向阀205进行气路切换,可在接口处形成负压气路,使得储水腔呈负压状态吸水;或在接口处形成正压气路,使得储水腔呈正压状态排水。
在一些实施例中,参见图12至图14b、以及图16g和图16h,基站还可以包括第二水箱2001,第二水箱2001可以为普通水箱,其无法实现自动上下水功能。
第二水箱2001被配置为可利用手动加入清水和/或去除污水。换句话说,第二水箱在使用方式上为常规水箱(无法在使用时自动上水和/或自动下水),其需要用户动手往其中加清水或者去除其中的污水,通常来讲需要在使用之前或者使用之后进行。
基站主体210可择一地供第一水箱201或第二水箱2001安装。
在一些实施例中,参见图11a至图14a,换向阀205设于第一水箱201,气泵Q设于基站主体210;
基站主体210设有至少两个接口,其中一个接口形成正压接口211,另一个接口形成负压接口212;

在基站主体210上,正压接口211与负压接口212均连接气泵,即负压接口212连接气泵的进气口,正压接口211连接气泵的出气口;气泵工作时,气体经负压接口212、气泵的进气口流入气泵,并自气泵的出气口流出至正压接口211经正压接口211流出。基站主体210安装第一水箱201时,正压接口211与换向阀205以及气泵的出气口连通,负压接口212与换向阀205以及气泵的进气口连通,第一水箱201的通气口202与换向阀205连通。第一水箱201通过换向阀205进行气路切换,可选择使其通气口202连通负压接口212所对应的负压气路,使得储水腔呈负压状态吸水;或选择使其通气口202连通正压接口211所对应的正压气路,使得储水腔呈正压状态排水。
如图15a至图15e所示,正压接口211设有与气泵的出气口连通的入气口213,以及有可供第一水箱201对接的对接口215,入气口213和对接口215连通;
在第一水箱201安装于基站主体210的状态下,负压接口212与第一水箱201连通,正压接口211的对接口215处于打开状态,以与第一水箱201对接连通;
在第二水箱2001安装于基站主体210的状态下,负压接口212与第二水箱2001连通,正压接口211与大气连通。
在一些实施例中,在第二水箱2001安装于基站主体210的状态下,正压接口211的对接口215可以处于封闭状态。具体可以通过第二水箱2001的外壁面覆盖在对接口215处,或者第二水箱2001上具有用于封闭对接口215的相关部件,使得对接口215处于封闭状态,又或者,对接口215处活动设置有可打开或封闭对接口215的封盖件。
参见图11a、图11b,图12以及图14a所示的气路原理图,当基站主体210安装第一水箱201时,负压接口212与第一水箱201连通,正压接口211的对接口215处于打开状态,且与第一水箱201对接连通。气泵在工作状态下,从负压接口212抽气以及从正压接口211的对接口215排气,从而可向第一水箱201提供负压或正压,第一水箱201通过换向阀205进行气路切换,可选择连通负压接口212所对应的负压气路,使得水箱呈负压状态吸水;或 选择连通正压接口211所对应的正压气路,使得水箱呈正压状态排水。
参见图12以及图14b所示的气路原理图,当基站主体210安装第二水箱2001时,负压接口212与第二水箱2001连通,正压接口211的对接口215处于封闭状态,气泵在工作状态下,从负压接口212抽气,从而可向第二水箱2001提供负压,使得第二水箱2001呈负压状态吸水。
如图16h所示,第二水箱2001可以包括清水箱2001a和污水箱2001b,清水箱2001a可以设有清水水路接口O1,污水箱2001b可以设有污水水路接口O2,以及通气口O,当第二水箱2001安装于基站主体210的状态下,第二水箱2001的清水水路接口O1与基站主体210上的出水接头2114对接连通,污水水路接口O2与基站主体210上的进水接头214对接连通。第二水箱2001的通气口O与基站主体210上的负压接口212连通。
其中,基站主体210包括壳体,可选地,气泵可以安装于壳体内或者气泵可以安装于壳体的外侧,负压接口212与正压接口211可设置于壳体表面,并对应第一水箱201和第二水箱2001在基站主体210上的安装位置布置。如此,在第一水箱201安装于基站主体210上时,第一水箱201与负压接口212以及正压接口211的对接口215对接连通;在第二水箱2001安装于基站主体210上时,第二水箱2001与负压接口212对接连通。另外,正压接口211的对接口215打开或封闭可通过多种方式实现,比如采用与对接口215相适配的盖板封堵对接口215,以使对接口215处于封闭状态;相应地,将盖板拿掉即可使对接口215处于打开状态,当然,此仅为示例性的,并非限制性的,包括但不仅限于此。本申请基站主体210实现气源兼容第一水箱201和第二水箱2001的适配使用,以进行基站主体210气源共用,无需在第一水箱201上额外设置气源,结构简单,成本低。
在一些实施例中,参见图11a、图11b、图12以及图14a,第一水箱201具有进水口203和排水口,换向阀205分别连接负压接口212、正压接口211、通气口202和大气环境;

第一水箱201的进水口203用于通过进水管道与基站主体210的进水接 头214连通。除通气口202以外,第一水箱201还具有进水口203和排水口217,可选地,换向阀205通过负压抽气管219连通基站主体210的负压接口212,通过正压进气管220连通基站主体210的正压接口211,通过通气管221连通第一水箱201的通气口202,以及通过排气管222连通大气环境。

在一些实施例中,参见图13、图15a和图15b,正压接口211还可以设有排气口216,排气口216与入气口213连通;
在第一水箱201安装于基站主体210的状态下,排气口216处于封闭状态,气泵输送的气体自入气口213、对接口215、换向阀205进入第一水箱201;
在第二水箱2001安装于基站主体210的状态下,气泵输送的气体自入气口213、排气口216排入大气。
在其他一些实施例中,如图15d~图15e所示,可以取消排气口216,当第二水箱2001安装于基站主体210时,气泵的气体从入气口213进入正压接口,并从正压接口上部的敞口直接流向大气环境。
基站主体210上安装第一水箱201时,以让排气口216处于封闭状态,气泵输送的气体自入气口213、对接口215、换向阀205进入第一水箱201。当前状态下,排气口216封闭,可保证正压接口211处经入气口213进入的气体通过对接口215正常向第一水箱201输送。进而,第一水箱201通过换 向阀205进行气路切换,可选择连通负压接口212所对应的负压气路,使得水箱呈负压状态抽水;或选择连通正压接口211所对应的正压气路,使得水箱呈正压状态排水。而基站主体210上安装第二水箱2001时,气泵输送的气体可自入气口213、排气口216排入大气,通过所设排气口216可实现气泵输送至正压接口211的气体泄放至大气环境中,以维持气泵的正常工作。其中,排气口216的打开或封闭可通过多种方式实现,比如,当第一水箱201安装于基站主体210时,第一水箱201上用于与正压接口211对接的进气接头可以封闭排气口216。或者,在排气口216处设置与排气口216相适配的盖板等封堵排气口216,以使排气口216处于封闭状态;相应地,将盖板拿掉即可使排气口216处于打开状态,当然,此仅为示例性的,并非限制性的,包括但不仅限于此。
在一些实施例中,参见图15a~图15c,正压接口211还包括形成于基站主体210上的凹陷部U,凹陷部U形成连通腔218;
连通腔218用于与入气口213、对接口215以及排气口216分别连通;
在第二水箱2001安装于基站主体210的状态下,气泵输送的气体自入气口213先进入连通腔218,再经排气口216排入大气(如图15b中虚线箭头所示为第二水箱2001安装于基站主体210时,气体在正压接口211的流经路径)。
基站主体210安装第一水箱201时,对接口215处于打开状态(如图15c所示),排气口216处于封闭状态,气泵输送的气体自入气口213、对接口215、换向阀205进入第一水箱201(图15c中虚线箭头所示为第一水箱201安装于基站主体210时,气体在正压接口211的流经路径);基站主体210安装第二水箱2001时,正压接口211的对接口215处于封闭状态,排气口216处于打开状态,气泵输送的气体自入气口213进入连通腔218,并经排气口216排入大气。
在一些实施例中,参见图15b,入气口213的气流通道的最大横截面小于连通腔218的气流通道的最大横截面,连通腔218的气流通道的最大横截面大于排气口216的气流通道的最大横截面。
其中,入气口213、连通腔218以及排气口216的气体通道的横截面均垂直于气体的流动方向。气泵输送的气体自入气口213进入连通腔218(气体通道的横截面由小变大),再从连通腔218流动至排气口216(气体通道的横截面由大变小)排入大气,经过多次气体通道的横截面大小变化,气体声波在横截面突变处发生反射而衰减噪声,从而可实现降噪消音的效果,因此,可以实现通过正压接口211的合理结构设计,实现消音腔的功能。
在一些实施例中,参见图15b至图16d,对接口215为内凹对接口215,第一水箱201包括凸出设置的进气接头209,进气接头209可插装至内凹对接口215内与其连通;或,
如图16a和图16b所示,对接口215为外凸对接口215,外凸对接口215位于凹陷部内,且从凹陷部的底部向上凸出,第一水箱201包括凸出设置的进气接头209,外凸对接口215可插装至进气接头209内与其连通。
第一水箱201与正压接口211的对接口215可分别采用外凸和内凹的对接结构设置,如图15b和图15c所示,即第一水箱201上设置外凸的进气接头209,与正压接口211的内凹对接口215插装对接连通。或者,第一水箱201与正压接口211的对接口215分别采用内凹和外凸的对接结构设置,如图16a至图16d所示,即第一水箱201上设置外凸的进气接头209,与正压接口211的外凸对接口215插装对接连通。上述两种对接结构设置,可以根据实际情况选用其中之一。
类似的,当对接口为外凸对接口215时,如图16e~图16f所示,正压接口同样可以取消排气口216,当第二水箱2001安装于基站主体210时,气泵的气体从入气口213进入正压接口,并从正压接口上部的敞口直接流向大气环境。
在一些实施例中,参见图15c和图16d,基站主体210还设有密封件223,密封件223可以设于对接口215与进气接头209之间。
密封件223用于实现第一水箱201与正压接口211的对接密封,保证气密性,防止气体从第一水箱201与正压接口211之间的对接间隙处流出。其中,根据正压接口211的对接口215为内凹或外凸的不同构造,密封件223的设置形式不同。
进一步的,参见图15c,对接口215为内凹对接口215时,密封件223可以套设于进气接头209的外周壁,密封件223与内凹对接口215的内侧壁抵接;
如图16d所示,对接口215为外凸对接口215时,密封件223设于进气接头209的内周壁,密封件223与外凸对接口215的外侧壁抵接。
如图15c所示,在对接口215为内凹对接口215时,密封件223套设在进气接头209上,以随进气接头209与内凹对接口215对接时,密封件223抵接内凹对接口215的内侧壁,可防止气泵输送至正压接口211的气体自进气接头209的外周壁与内凹对接口215的内侧壁之间泄漏流出至大气环境,进而保证气密性。如图16d所示,在对接口215为外凸对接口215时,密封 件223设于进气接头209的内周壁,以随进气接头209与外凸对接口215对接时,密封件223抵接外凸对接口215的外侧壁,可防止气泵输送至正压接口211的气体自外凸对接口215的外周壁与进气接头209的内侧壁之间泄漏流出至大气环境。
进一步的,如图15c所示,对接口215为内凹对接口215时,密封件223的外周壁可以凸设有多个环形凸起224,并通过环形凸起224与内凹对接口215的内侧壁抵接;
如图16d所示,对接口215为外凸对接口215时,密封件223的内周壁凸设有多个环形凸起224,并通过环形凸起224与外凸对接口215的外侧壁抵接。
其中,密封件223上具有多个环形凸起224,多个环形凸起224在密封件223的外周壁依次间隔设置,且可以与密封件223一体成型。进气接头209与对接口215对接时,密封件223通过环形凸起224与对接口215的侧壁抵接,可形成多级密封,可以进一步提高气密性。
在一些实施例中,参见图15c,对接口215为内凹对接口215时,密封件223上形成有延伸部225;延伸部225位于密封件223朝向内凹对接口215的一端,且与内凹对接口215的内侧壁之间形成有形变腔O,延伸部225在通气状态下朝向形变腔O发生形变。
示例性的,密封件223上的延伸部225可以呈中空圆台状,朝向密封件223的中心线延伸聚拢。如图15c所示,当气泵输送气体进入正压接口211时,因受到气体气压的作用,密封件223的延伸部225朝向形变腔O发生形变,进而具有紧贴于内凹对接口215的内侧壁的趋势,从而进一步提高气密性。
在一些实施例中,参见图12、图15b和图16b,基站主体210还包括:
封盖件226,封盖件226与对接口215活动连接或可拆卸连接,以用于封闭或打开对接口215。
其中,基站主体210安装第一水箱201时,通过封盖件226打开对接口215,以使第一水箱201可与对接口215对接连通,进而正压接口211可向第一水箱201供气;基站主体210安装第二水箱2001时,无需与正压接口211对接连通,通过封盖件226封闭对接口215。
可选地,封盖件226与对接口215活动连接,设置形式可为多种,比如封盖件226为盖板,且在对接口215处滑动设置或转动设置等,此仅为示例性的,并非限制性的,包括但不仅限于此;或者,封盖件226与对接口215可拆卸连接,设置形式可为多种,比如,封盖件226为盖板,且在对接口215 处卡扣连接或通过紧固件连接等,或者封盖件226为胶塞,且在对接口215处过盈配合设置,此仅为示例性的,并非限制性的,包括但不仅限于此。
在一些实施例中,参见图15b和图16b,封盖件226用于安装于凹陷部的开口处,以用于阻碍气流从对接口215流出,进而使得从入气口213进入的气流经过连通腔218后从排气口216排出。
在一些实施例中,封盖件226包括刚性件和/或弹性软塞。根据实际情况设置,且对其外形构造不作限制。
本申请还提出一种清洁系统,包括如前述实施例记载的基站以及清洁设备。该基站的具体结构参照上述实施例,由于本清洁系统采用了上述所有实施例的所有技术方案,因此至少具有上述实施例的技术方案所带来的全部技术效果,在此不再一一赘述。
发明人经过创造性劳动发现,为实现水箱自动吸排水可采用气源作为动力源,在气源与水箱之间设置气道管路以及阀门,通过阀门控制管路中的气道变换,当气源施加负压时进行吸污水,当气源施加正压时进行排水。
在水箱的气道管路中,通常是使用两个二位三通电磁阀控制气道变换,不仅成本高,而且使得管路设置复杂,容易装错,影响正常使用。
本申请还提出一种换向阀301,参见图17至图19,包括:
壳体302,壳体302的表面设有至少四个气孔303;
换向件304,换向件304可活动的设置在壳体中,换向件304形成有至少两个相互独立的通道305,每一通道305连通其中两个气孔303;
驱动件306,驱动件306设置于壳体302上,且与换向件304传动连接,驱动件306驱动换向件304活动,以切换通道305与不同气孔303之间的连通。
本实施例所提出的换向阀301可应用于清洁系统基站,以实现水箱的气路切换,使得水箱内部呈负压状态吸水或呈正压状态排水。当然,换向阀301的应用场景包括但不仅限于此。具体地,换向阀301的壳体302可以包括第一壳体和第二壳体,第一壳体与第二壳体可拆卸连接,并对接形成内部的容纳腔;可拆卸连接形式可以包括螺钉连接、卡扣连接等,根据实际情况设置。
换向件304位于壳体302内部的容纳腔中,壳体302表面所设的气孔303贯穿壳体302,于内可对接换向件304上的通道305进行连通,于外连接气管。在换向件304上,通道305开口显露于换向件304的表面,以从壳体302内的表面对接气孔303进行连通。气孔303至少四个,通道305至少为两个且各通道305之间相互独立,每一通道305连通其中两个气孔303。也就是说, 气孔303可以为四个,或六个、八个不等,比如,当气孔303为四个时,换向件304上的通道305可以对应设置两个,一个通道305连通其中相邻的两个气孔303,另一个通道305连通另外相邻的两个气孔303;当气孔303为六个时,换向件304上的通道305可以对应设置三个,六个气孔303中两两相邻的气孔303为一组,以分别被三个通道305连通。根据此设置形式,气孔303为八个或其它数量的情况可依次类推。即在相应通道305的连通下,两个气孔303之间相连通,经一个气孔303流入的气体可流动经过通道305再于另一个气孔303流出。
在驱动件306的驱动下,换向件304活动,换向件304上的通道305随之变换位置,进而切换通道305与不同气孔303之间的连通。其中,换向件304的活动形式可以是转动、平动(即平行移动)或其它。比如,当换向件304为转动设置时,气孔303在壳体302上可以是呈周向排布间隔设置,通道305对应在换向件304上沿周向依次设置;相应地,驱动件306可采用电机或其它动力源,并可通过采用齿轮组或蜗轮蜗杆或传动带等向换向件304传递驱动动力。当换向件304为平动设置时,气孔303在壳体302上可以是呈直线排布间隔设置,通道305对应在换向件304上沿直线依次设置,驱动件306可对应采用气缸或电机或其它动力源,当采用电机时,并且可通过采用丝杠或齿轮齿条或摩擦轮等向换向件304传递动力。另外,当换向件304采用不同的活动形式且采用不同的传动结构时,驱动件306所采用的电机可以是固定在壳体302上的,也可以是固定在换向件304上的,根据实际情况设置。
本换向阀301的气路切换原理为:换向阀301中换向件304上的一个通道305连通两个气孔303,进而使得对应气孔303连接的两气管连通;换向阀301的驱动件306驱动换向件304活动,以使通道305变换位置,从而切换掉通道305所连通的两个气孔303中的至少一个,而转换与其它气孔303连通,进而使得不同气管连通,实现气路切换。
换向阀301应用于清洁系统基站时,根据水箱所设的气道管路中的正压进气管、通气管、负压抽气管和排气管的一端分别连接换向阀301的四个不同气孔303,而正压进气管的另一端进气,通气管的另一端连接水箱,负压抽气管的另一端出气,排气管的另一端连通大气环境。
通过换向阀301进行气路切换,负压抽气管与通气管连通,正压进气管与排气管连通时,水箱中的气体依次经通气管、换向阀301进入负压抽气管中,水箱内部形成负压,可使得水箱进水;正压进气管中的气体依次经换向阀301、排气管排入大气环境;
正压进气管与通气管,负压抽气管与排气管连通时,正压进气管中的气体依次经换向阀301、通气管进入水箱,水箱内部形成正压,可使得水箱排水;大气环境中的气体依次经排气管、换向阀301进入负压抽气管中。
单个阀体即可解决现有的两个二位三通电磁阀所解决的问题,减少了阀体数量,降低了成本;并且,换向阀301仅需连接正压进气管、通气管、负压抽气管和排气管,管路中的管体数量也相应减少,管路设置变得简单,不容易装错,且进一步降低了成本。
