Description

储液箱、清洁基站、阀体组件、水箱和供水系统 技术领域
本申请涉及清洁设备领域。
背景技术
随着科技的发展,清洁设备的种类与功能也越来越齐全。清洁设备可包括清洁机器人及可对清洁机器人进行护理的基站,比如清洗护理,当清洁机器人放置于基站时,基站可以向清洁机器人喷水,以对其清洁件进行清洗。
对于自动上下水的基站而言,基站通过水管连接至水龙头等外部水源,外部水源的水提供给基站水箱补水。
在相关技术中,现有清洁基站的水箱中的水位下降后,例如执行洗拖布用水后,补水动力元件和/或控制元件即会启动,使外部水源进入到水箱,也即随用随补。如此,则需要动力元件或控制元件反复工作,导致其开关频率较高,容易损坏,从而增加维护成本。

施力件50,施力件50用于向封堵件40施加作用力,以使得封堵件40在箱体10内的液位未下降至预设液位时,保持关闭气口30的状态。
本实施例中,储液箱应用于具有自动上下水功能的基站,其中,上水是指将外部的液体抽入至储液箱内,下水是指将储液箱内的液体抽出至外部。比如,储液箱为清水箱,则基站对储液箱进行上水即为将外部清水抽入至清水箱内,同理,基站对储液箱进行下水即为将清水箱内的清水抽出至外部,以用于清洗基站的护理区域和/或清洁机器人的拖布等。
储液箱可以采用气动的方式进行液体的抽排,也即本储液箱需配备一个气泵进行使用。具体的,储液箱包括有箱体10,箱体10设置有进液口20和气口30,进液口20用于供外部液体自此流入至箱体10内,气口30与气泵的进气端连通,以用于供气泵将箱体10内的气体自此气口30抽出至外部,使 得储液箱内产生负压,进而使得外部液体在大气压与储液箱内部气压的压差之下流入至箱体10内。
气泵通过气口30对箱体10抽负压后,外部液体将逐渐流入箱体10,在液体流入箱体10的过程中,位于箱体10内的封堵件40将受到液体浮力的作用,使得封堵件40随着箱体10内液面的上升而逐渐上升。待箱体10内的液位达到预设液位后,封堵件40将上升至封堵气口30的位置,此时,由于气口30被封堵住,因此,气泵也就无法再对箱体10内部的气体进行抽排,也即:当封堵件40封堵气口30后,表示箱体10内液位已经到达最大限定液位。
由于施力件50向封堵件40施加阻碍其向下掉落的作用力,以下将该作用力称作为阻落力,阻落力与封堵件40所受到的液体浮力的方向一致,而与封堵件40所受到的重力的方向相反。也即:封堵件40在竖直方向上受到了三个作用力,分别为阻落力、液体浮力和重力,阻落力与液体浮力的方向竖直向上,重力的方向竖直向下。在箱体10内液位为预设最大液位时,施力件50所提供的阻落力与封堵件40所受的液体浮力的合力大于重力,封堵件40处于封堵气口30的状态。
随着液位的上升,封堵件40浸入液体的体积越大,则所受浮力越大,封堵件40越不易掉落;而随着液位的下降,封堵件40浸入液体的体积越小,则所受浮力越小,封堵件40越容易掉落。当箱体10内的液体开始向外部抽排时,箱体10内的液面将逐渐下降,封堵件40浸入液体的体积逐渐减小,封堵件40所受到的液体浮力也将逐渐减小,在减小至小于重力时,由于阻落力的存在,因此,封堵件40仍然不会向下掉落,而是继续保持在封堵气口30的位置处。而后,箱体10内的液体继续向外抽排,封堵件40所受到的液体浮力也将继续减小,在减小至与阻落力的合力小于重力时,封堵件40将在重力的作用下掉落,使得封堵件40与气口30脱离,此时,气口30被打开,箱体10内可以通过气泵抽负压,实现进液。在一些实施例中,可以具体设计封堵件40的体积、重量,及/或施力件50的结构和性能,以使得在液位下降至尽量低的程度,才使得封堵件40掉落而打开气口30,例如,可以在箱体10内的液体全部排空或几乎排空时,封堵件40才掉落。也就是说,可以实现在箱体10内的液体基本被排空的状态下才进液。而在进液过程中,封堵件40随着进液进行,封堵件40不断上升,直至到达预设最大液位,在施力件50和封堵件40所受液体阻力的共同作用下,维持在关闭气口30的状态。
为方便理解,以下结合储液箱的具体应用场景进行描述:
比如,假设储液箱为清水箱,清水箱的容量为30L,并且清水箱内已装满清水,此时,封堵件40处于封堵气口30的位置处,其同时受到施力件50所施加的阻落力以及液体浮力的作用。
当清水箱开始向外部抽排清水时,清水箱内的液面逐渐下降,封堵件40所受到的液体浮力也将逐渐减小。
假设,在清水箱内的液面下降至20L时,封堵件40所受到的液体浮力减小至小于重力。此时,若封堵件40没有受到施力件50所施加的阻落力的作 用,封堵件40将在重力的作用下向下掉落,使得气口30被打开。由于清水箱内的液位下降,基站的供水系统的控制元件将立即启动,以控制气泵对清水箱内进行抽气,从而产生负压,进而使得外部清水流入至清水箱内,直至清水箱内清水充满,也即清水箱内的液面达到30L。如此,储液箱便需要随用随补,导致动力元件(也即气泵)或控制元件的开关频率变高,使得动力元件或控制元件容易损坏,增加维护成本。
由于本申请所提出的储液箱还设置有施力件50,施力件50将在封堵件40封堵气口30时对其施加一个阻落力,可使得封堵件40在清水箱内的清水全部排空或几乎排空时方才掉落,从而打开气口30。比如,假设在清水箱内的液面下降至0时,封堵件40此时仅受到重力和阻落力的作用,而阻落力小于重力,因此,封堵件40将在重力作用下掉落,从而打开气口30。或者,假设在清水箱内的液面下降至2L时,封堵件40所受到的液体浮力减小至与阻落力的合力小于重力,此时,封堵件40将在重力作用下掉落,从而打开气口30。如此,储液箱则无需随用随补(只要用水,便需要补水),从而可减小动力元件或控制元件的开关频率,使得动力元件或控制元件不容易损坏,降低维护成本。
需要说明的是,外部液体是指储液箱外的液体,可以是由外部的水龙头所提供的自来水,也可以是由外部的其他实体水源端所提供的清水,外部液体通过管路输送至储液箱内。当储液箱安装于基站时,储液箱可以外部水来源可以为水龙头,或者也可以为设于基站外部的水箱。
在一些实施例中,施力件50设于箱体10与封堵件40之间,用于提供阻碍封堵件40下降的阻力;当箱体10内的液位高于或等于预设液位时,施力件50保持关闭气口30的状态;当箱体10内的液位低于预设液位时,施力件50打开气口30。
本实施例中,施力件50设置在箱体10与封堵件40之间,在封堵件40随着液面上升运动至封堵气口30时,施力件50将向封堵件40施加一个用于阻碍封堵件40下降的阻力,也即阻落力F阻落(此时,F阻落+F浮>G)。其中,阻落力F阻落的大小决定了封堵件40打开气口30时箱体10内的液体剩余量的多少,也即:在箱体10内的液体剩余量低于预设液位时,封堵件40所受到的液体浮力F浮与阻落力F阻落的合力将小于重力G(F浮+F阻落<G),使得封堵件40在重力的作用下掉落,从而打开气口30。在箱体10内的液体剩余量高于预设液位时,封堵件40所受到的液体浮力F浮与阻落力F阻落的合力始终大于重力G(F阻落+F浮>G),使得封堵件40始终封堵气口30。
进一步的,施力件50向封堵件40所施加的阻落力F阻落越大,封堵件40打开气口30时,箱体10内的液体剩余量也就越少,相反,施力件50所施加的阻落力越小,封堵件40打开气口30时,箱体10内的液体剩余量也就越多。比如,当施力件50向封堵件40所施加的阻落力F阻落为40N时,在封堵件40打开气口30时,箱体10内的液体剩余量可以为2L。再比如,当施力 件50向封堵件40所施加的阻落力F阻落为50N时,在封堵件40打开气口30时,箱体10内的液体剩余量可以为1L。再比如,当施力件50向封堵件40所施加的阻落力F阻落为30N时,在封堵件40打开气口30时,箱体10内的液体剩余量可以为3L。
在一些实施例中,施力件50沿气口30的周向均匀或对称布置。
本实施例中,为使得封堵件40受力均衡,施力件50沿气口30的周向均匀布置,或者,施力件50沿气口30的周向对称布置。如此,在封堵件40封堵气口30时,由于施力件50所施加的阻落力F阻落可以尽量均匀作用于封堵件40上,因此,在箱体10内的液面逐渐下降至封堵件40所受到的液体浮力小于重力时,封堵件40不会朝向气口30的某一侧偏移,比如,左侧或右侧,从而保证封堵件40完全封堵住气口30。
进一步的,假设施力件50所施加的阻落力F阻落作用于封堵件40时是不均衡的,比如,封堵件40靠近气口30左侧的位置所受到阻落力为40N(以下称作为第一阻落力),而封堵件40靠近气口30右侧的位置所受到的阻落力为60N(以下称作为第二阻落力)。如此,在液体浮力F浮减小至与第一阻落力的合力小于重力,而液体浮力F浮与第二阻落力的合力大于重力时,封堵件40的左侧部分将与气口30脱离,导致封堵件40不能完全封堵住气口30,从而导致封堵件40无法可靠封堵气口3。

本申请一些实施例还提出一种储液箱,其采用水泵对其内的液体进行抽排,该储液箱包括:
箱体10,箱体10设置有进液口20’,进液口20’用于供水泵将外部液体抽入至箱体10内;
封堵件40,封堵件40设置在箱体10内,封堵件40可在液体浮力的作用下关闭进液口20’;
施力件50,施力件50用于向封堵件40施加作用力,以使得封堵件40在箱体10内的液位未下降至预设液位时,保持关闭进液口20’的状态。
本实施例中,参照附图6,进液口20’设置在箱体10的顶部,其通过管路与水泵连接,水泵用于将箱体10内的液体抽出至外部,或者将外部的液体抽入至箱体10内。
随着液位的上升,封堵件40浸入液体的体积越大,则所受浮力越大,封堵件40越不易掉落;而随着液位的下降,封堵件40浸入液体的体积越小,则所受浮力越小,封堵件40越容易掉落。当箱体10内的液体充满时,封堵件40在液体浮力F浮的作用下浮动至封堵进液口20’的位置处,同时,施力件50向封堵件40施加一个用于阻碍其向下掉落的阻落力F阻落(此时,F阻落+F浮>G)。当箱体10内的液体开始向外部抽排时,箱体10内的液面将逐渐下降,封堵件40浸入液体的体积逐渐减小,封堵件40所受到的液体浮力F浮也将逐渐减小,在减小至小于重力G时,由于阻落力的存在,因此,封堵件40仍然不会向下掉落,而是继续保持在封堵进液口20’的位置处。而后,箱体10内的液体继续向外抽排,封堵件40所受到的液体浮力也将继续减小,在减小至液体浮力F浮与阻落力F阻落的合力小于重力G时(F浮+F阻落<G),封堵件40将在重力G的作用下掉落,使得封堵件40与进液口20’脱离,此时,进液口20’被打开,水泵将外部液体抽到箱体10内。在一些实施例中,可以具体设计封堵件40的体积、重量,及/或施力件50的结构和性能,以使得在液位下降至尽量低的程度,才使得封堵件40掉落而打开进液口20’,例如,可以在箱体10内的液体全部排空或几乎排空时,封堵件40才掉落。也就是说,可以实现在箱体10内的液体基本被排空的状态下才进液。而在进液过程中,封堵件40随着进液进行,封堵件40不断上升,直至到达预设最大液位,在施力件50和封堵件40所受液体阻力的共同作用下,维持在关闭进液口20’的状态。

在不相互矛盾的情况下,本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
本申请实施例涉及的清洁设备可以是包括但不限于清洁机器人、基站或手持清洁设备等,其中,基站是指与清洁机器人或手持清洁设备配合使用的清洁设备。以基站为例,为了方便用户的使用,往往通过基站配合清洁机器人的使用,为清洁机器人提供护理。例如,基站可用于对清洁机器人进行充电,当在清洁过程中,清洁机器人的电量少于预设电量阈值时,清洁机器人可移动到基站处,进行充电。对于清洁机器人来说,基站还可以清洁拖擦件(如拖布),清洁机器人的拖擦件拖擦地面后,拖擦件往往变得脏污,需要对其进行清洗。为此,基站可用于对清洁机器人的拖擦件进行清洗。具体来说,清洁机器人可移动到基站上,从而基站上的清洁机构对清洁机器人的拖擦件进行自动清洗。基站除了实现上述功能,还可以通过基站对清洁机器人进行维护和管理,使清洁机器人在执行清洁任务的过程中,更加智能地对清洁机器人进行控制,提高机器人工作的智能性。
为了实现对清洁机器人的拖擦件进行清洗,基站内部设置有水路系统,水路系统可以包括清水箱,通过清水箱的入水口可以接入外部供水端的水,实现基站自动补水;可以将清水箱的水通过水路通道输送至需要用水的区域,例如,在需要进行拖擦件清洗时,可以将清水箱的清水输送至清洗区,在清洗区对拖擦件进行供水,以进行拖擦件清洗。基站除了给清洁机器人进行洗拖布等维护和管理,还可以进行自清洁任务,基站可以对内部的清洗区进行自清洁,以将清洗区积攒的污渍进行清洁。水路系统还可包括污水箱,完成拖擦件清洗后,可以将清洗区的污水输送至污水箱,通过污水箱进行收集,污水箱可执行抽水操作,将清洗区的污水吸至污水箱,污水箱起到收集污水的作用,可以将污水箱通过排水通路排出至外部,例如,可以在污水箱的污水量达到一定污水量阈值后,执行排水操作,将污水箱的污水排到外部。
在一些实施方式中,基站内部的清水箱可以通过外部水源的水压实现进水,该“外部水源”可以为具有一定水压的市政水源,例如可以是用户家里的水龙头,同时,还需要在外部水源与基站之间的外部管路上设置电磁阀,利用电磁阀实现供水水路的启闭和切换等功能。
考虑到电磁阀成本较高,在一种实施方式中,可以省去电磁阀,通过气动抽负压的方式控制通往基站的水路系统,为此,需要在供水进入基站前降低基站进水管路的水压,使得清水箱的进水也通过气动实现。基于这一需求,本实施例提供了一种水箱,该水箱连接外部水源以缓存来自外部水源的水,相当于将市政水源的水压经过该水箱降压,而基站连接该水箱,进而可以利用泵体泵送该水箱的水至基站。特别的,可以实现气动抽负压进清水。该水箱相对于基站可以更靠近外部水源,例如,水箱可以直接连接在水龙头处,水箱的进水口与外部水源之间省去连接管路,可以避免连接管路水压过高漏水或爆裂。水箱的出水口则通过外部进水管路连接至基站,从而为基站提供减压后的水。如此,可以通过设置在靠近基站或基站内的水泵或气泵抽负压将外部水源处水箱的水抽向基站。
如图12A~12D,示出了本申请实施例的清洁设备的四种不同的供水方式 示意图。如图12A,供水系统包括设于外部水源10所在侧的水箱30和远离外部水源10的基站20,从外部水源10注入的高压水(市政水源的水)经水箱30减压后缓存于水箱30中,再供给至基站20;图12B中,供水系统还包括泵体1,泵体1设于水箱30内,泵体1可以提供一定的泵水压力,将水箱30内的缓存水泵出水箱30外;图12C中,泵体1设于水箱30与基站20之间的进水管路上;图12D中,泵体1设于基站20内,作为基站20的一部分,连接在进水管路和清水箱之间,利用基站20端的负压从水箱30内泵水。上述供水系统与清洁机器人协同运行,二者作为清洁机器人系统的主要组成部分。
如图13,本实施例提供了一种水箱30,该水箱30可用于连接在外部水源10和清洁设备的基站20之间提供缓存水,具有减压和防漏水的功能。该水箱30主要包括箱体31和第一开关组件K1,箱体31上设有进水口32和出水口33,进水口32用于连接外部水源10,出水口33用于连接基站20。第一开关组件K1设于箱体31内,用于选择性地切断或导通箱体31与外部水源10之间的液流通道。在箱体31内液位达到第一预设高度H1前,第一开关组件K1使得液流通道保持导通状态,此时,箱体31可以正常补水,在箱体31内液位达到第一预设高度H1后,开关组件切断液流通道,外部水源10的水无法再进入箱体31内。
需要说明的是,本申请实施例中所提供的开关组件可以是机械式的开关组件,如浮球阀等,可在水位到达设定水位时,自动关闭进水通道。在其他一些实施例中,开关组件也可以为电控阀门,例如电磁阀等,箱体31内可以设置水位检测组件,水位检测组件与电磁阀连接,电磁阀用于在水位检测组件所检测的水位达到预设高度时,控制液流通道关闭。
本实施例的水箱提供了水压缓存空间,其内部的第一开关组件K1可以将水箱内的液位限制在第一预设高度H1内,当水箱内的液位达到第一预设高度H1后无法继续为水箱补水,因此可以使得水箱的水压保持在一定的水平以下,也可以避免水箱内的水满而溢出。
如图14,在其中一个实施例中,第一开关组件K1用于在箱体31内液位达到第一预设高度H1后,关闭进水口32。示例性地,第一开关组件K1包括阀门组件34和第一浮动件35,阀门组件34用于控制进水口32启闭状态,例如,阀门组件34可以是设于进水口32内的机械阀,第一浮动件35可随箱体31内液位的升降而选择性地操作阀门组件34,改变阀门组件34的工作状态,以使阀门组件34在箱体31内液位达到第一预设高度H1时关闭进水口32。
例如,第一浮动件35可以设于阀门组件34下方,阀门组件34初始状态为打开状态,当第一浮动件35随液位上升后,通过顶推上方的阀门组件34而关闭进水口32。
在一个实施方式中,阀门组件34包括设于进水口32的阀门、用于触发阀门关闭的触发件341和沿箱体31的高度方向延伸的第一导向件342,第一浮动件35活动地套设于第一导向件342上,以在水的浮力作用下沿第一导向 件342移动而选择性地推动触发件341,从而关闭阀门。该触发件341可以是一端相对于阀门铰接,另一端为朝下伸出的自由端,该自由端可位于第一浮动件35与阀门之间,当第一浮动件35上浮时触发件341被朝上推压,从而推动阀门闭合。示例性地,触发件341的中部还可以设有长孔,第一导向件342穿过该长孔,触发件341在摆动的过程中可以借助第一导向件342进行限位。第一浮动件35可以是球形、柱形等,其形状不限于此。
除此之外,水箱30还可以包括防虹吸阀38,防虹吸阀38设于箱体31内,并连通出水口33,防虹吸阀38为常闭单向阀,打开的方向为从水箱30内向出水口33的方向。初始状态下,防虹吸阀38处于闭合状态,可以防止水箱30外的水从出水口33倒流回水箱30。在水压的作用下防虹吸阀38可供水流单向通过。在其他实施方式中,防虹吸阀38也可以设于水箱30外。
在一个实施方式中,出水管37设于箱体31内并连接出水口33,出水管37的末端延伸至第二腔Q2的底部,以使箱体31内液位较低时仍能正常供水。水箱还可以包括过滤元件36,过滤元件36设于出水口33的上游,箱体31内的水经过滤元件36过滤后从出水口33流出。例如,过滤元件36连接于出水管37的底端,其底部可固定或支撑于在箱体31的底部。过滤元件36可以包括中空的主体部和设于主体部外壁上的过滤网,进水口32进入的水经过滤元件36的过滤网进入主体部内,并由主体部依次经出水管37、出水口33、进水管路供应至基站20。过滤元件36可以对过滤水源中的异物,同时,还可以通过在过滤元件36的主体部内放置阻垢剂、活性炭等净化水质的物质。
由于本实施例的水箱提供了水压缓存空间,其内部设有可随液位升降自动切换进水口启闭状态的浮动件,当液位过高时,浮动件可在浮力作用下自动切断外部水源的供应,当液位过低时浮动件随之下降而自动连通外部水源,既可使得从水箱流出的水压相比外部水源进入的水压更低,又使得水箱内的液位始终不会高于预设高度,从而可避免水管和基站因水压过高而损坏、漏水,也避免了水箱内的水溢出。
如图15~17,本实施例示出了另一种水箱30,开关组件包括第一开关组件K1和第二开关组件K2,第一开关组件K1用于在箱体31内液位达到第一预设高度H1后,关闭进水口32,第二开关组件K2用于在箱体31内液位达到第二预设高度H2时,切断进水口32和出水口33之间的液流通道。需要说明的是,第一预设高度H1、第二预设高度H2均低于箱体31内表面,即,液面在第一预设高度H1、第二预设高度H2时均未充满水箱30。
如此,通过第一开关组件K1可以使得箱体31内液位被限制在第一预设高度H1以内,通过第二开关组件K2可以使得箱体31内液位被限制在第二预设高度H2以内。当箱体31内同时设置有第一开关组件K1、第二开关组件K2时,可以起到双重保障,使得箱体31内的水无法超出所规定的高度。例如,当第二预设高度H2高于第一预设高度H1时,第二开关组件K2可以在第一开关组件K1故障时进一步保证箱体31内的水不超过第二预设高度H2,从而防止箱体31内的水溢出。
如图16,本实施例中,箱体31包括第一腔Q1和第二腔Q2,第一腔Q1和第二腔Q2通过第一通孔301h彼此连通,进水口32连通第一腔Q1,出水口33连通第二腔Q2。第一开关组件K1、第二开关组件K2均设于第一腔Q1内,第二开关组件K2用于在箱体31内液位达到第二预设高度H2时封堵第一通孔301h。
可以理解的是,在其他实施方式中,箱体31内可以仅设有第一开关组件K1,也可以仅设有第二开关组件K2,均能实现切断外部水源10与箱体31的出水口33之间液流通道的功能。
在一个实施方式中,第二开关组件K2包括第二浮动件300和阻挡件301a,第二浮动件300可随箱体31内液位的上升而升高,阻挡件301a连接第二浮动件300,用于在箱体31内液位达到第二预设高度H2时,在第二浮动件300带动下运动而封堵第一通孔301h,从而切断第一腔Q1和第二腔Q2之间的液流通道。当第一通孔301h被阻挡件301a封堵后,即使外部水源10仍能从进水口32朝箱体31内注水,水仅能进入第一腔Q1,第二腔Q2内仍保持第二预设高度H2,且第二腔Q2内的压力可以维持在较低水平。
图16和图17分别示出了第二浮动件300封堵第一通孔301h和不封堵第一通孔301h的状态,在箱体31内液位低于第二预设高度H2时,阻挡件301a与第一通孔301h具有间隔,第一腔Q1和第二腔Q2连通,在箱体31内液位达到第二预设高度H2时,阻挡件301a挡住第一通孔301h,第二腔Q2内的液位不再升高。
如图16所示的实施方式中,第二浮动件300与阻挡件301a通过连接件301b连接,连接件301b与箱体31转动连接,阻挡件301a和第二浮动件300分别位于连接件301b的转动中心的两侧,使得在第二浮动件300上升过程中阻挡件301a反而下降,阻挡件301a在连接件301b的带动下朝向第一通孔301h移动。为了可靠地封堵第一通孔301h,连接件301b的转动中心到第二浮动件300的力臂大于其到阻挡件301a的力臂,可以使得阻挡件301a作用在第一通孔301h上的力被放大。
当箱体31内同时设置有第一开关组件K1、第二开关组件K2,且第二预设高度H2高于第一预设高度H1时,正常情况下,外部水源10在朝向箱体31供水的过程中,当液位逐渐上升至第一预设高度H1时,第一浮动件35上浮,推动触发件341,从而关闭阀门组件34,进水口32无法继续进液,第一腔Q1和第二腔Q2的液面维持在第一预设高度H1;当第一开关组件K1出现故障,例如,当第一浮动件35被第一导向件342卡住无法推动触发件341时,进水口32继续进液,当第一腔Q1和第二腔Q2的液面上升至第二预设高度H2时,第二浮动件300上升,使得阻挡件301a朝向第一通孔301h运动并封堵第一通孔301h,第一腔Q1和第二腔Q2的液面维持在第二预设高度H2。
在一些实施例中,箱体31可以包括隔离板301,第一通孔301h开设于隔离板301上,隔离板301将箱体31内的空间分隔为第一腔Q1和第二腔Q2。示例性地,如图16,隔离板301包括侧板3011和挡板3012,侧板3011沿箱 体31的高度方向延伸,挡板3012与侧板3011、箱体31围成第一腔Q1,第一通孔301h开设于挡板3012上。挡板3012可以是与箱体31的底面平行设置,侧板3011可以与挡板3012相互垂直。这里,隔离板301仅为形成于箱体31顶部和侧壁之间的板状构造,在其他实施方式中,隔离板301也可以为独立的筒体结构,可拆卸地安装到箱体31内。箱体31也可以由顶盖和顶部开口的仓体组成,进水口32、出水口33、阀门组件34的一个或多个设置在顶盖上。
结合图16~图19,本实施例的过滤元件36设于水箱30的第二腔Q2内,过滤元件36的进水端连通第一通孔301h,过滤元件36的出水端,如过滤网,连通第二腔Q2。示例性地,箱体31的底板上设有安装孔303,过滤元件36通过安装孔303可拆卸地连接到箱体31的底部。例如,水箱30还包括安装座361,过滤元件36固定到安装座361上,或与安装座361一体设置,安装座361的外表面设有一圈螺纹,安装孔303设有内螺纹,通过将安装座361旋入安装孔303,可将过滤元件36安装到箱体31的底板,使过滤元件36的进水端抵接挡板3012并连通第一通孔301h。
在一个实施方式中,水箱30还具有复位机构39,复位机构39可用于在进水口32和出水口33之间的液流通道被第二开关组件K2切断后,恢复进水口32和出水口33的连通。
在一个实施方式中,复位机构39设于箱体31,且至少部分伸入箱体31内,用于接收预设外力而驱动第二开关组件K2运动,使第一通孔301h导通。具体地,当箱体31内液位达到第二预设高度H2时,阻挡件301a在第二浮动件300带动下运动而封堵第一通孔301h,此时,用户可通过复位机构39按压箱体31内的第二浮动件300,第二浮动件300在被按压后下降,使阻挡件301a翘起而不再封堵第一通孔301h,第一腔Q1和第二腔Q2可恢复连通。例如,复位机构39可被按压,并可在被按压后驱动第二开关组件K2运动;或者复位机构39可被旋入旋出,并可在被旋转后驱动第二开关组件K2运动。
在一个实施方式中,请参照附图16,复位机构39包括杆体391和位于箱体31内的限位件393,箱体31具有第二通孔,杆体391的一端穿过第二通孔而插入箱体31内,限位件393套设于杆体391的外壁上,用于限制杆体391从箱体31内脱出。
在一个实施方式中,复位机构39还可包括密封件390,密封件390可设于杆体391的外壁,位于限位件393上朝向箱体31的一侧,用于与箱体31的内壁抵接而封堵杆体391与第二通孔的孔壁之间的间隙,实现杆体391与箱体31之间的密封,防止箱体31内的水从杆体391的第二通孔处泄露。在其他实施方式中,密封件390也可以与限位件393间隔设置,仅封堵杆体391与第二通孔之间的间隙。
在一个实施方式中,为了实现杆体391被按压后撤去外力可自动复位,复位机构39还可以包括套设于杆体391上的弹性件392,弹性件392安装于杆体391与箱体31之间,以使限位件393弹性抵接在箱体31内表面。例如, 弹性件392位于箱体31外,被压缩于杆体391上位于箱体31外的端部与箱体31的外表面之间,当外力撤去后,限位件393在弹性件392的作用下被弹性抵接在箱体31内表面;或者,弹性件392位于箱体31内而处于伸长状态,其两端分别拉紧杆体391与箱体31的内壁,使二者产生相互靠近的趋势,从而使限位件393抵紧在箱体31内表面。
在一些实施方式中,当第一开关组件K1出现故障后,液位维持在第二预设高度H2时,阻挡件301a还可在复位机构39按压第二浮动件300后翘起而拨动第一开关组件K1的第一浮动件35,开启进水口32的同时,还能解除第一浮动件35的卡死状态。
在使用水箱30的过程中,外部水源10的高压水从进水口32进入水箱30,水箱30内的液位上升带动第一浮动件35上升,当液位上升至第一预设高度H1时,第一浮动件35触发阀门组件34关闭进水口32,水箱30停止进水,第一腔Q1内的水可以正常经过滤元件36进入第二腔Q2,通过出水口33流出,为基站20供水;当液位上升至第一预设高度H1但第一浮动件35未正常工作时,进水口32继续进水,第二浮动件300随液位上升,当液位上升至第二预设高度H2时,第二浮动件300触发阻挡件301a封堵第一通孔301h,虽然进水口32可以继续进水,但是水压被密封在第一腔Q1内,不会影响到第二腔Q2的水压;当第一浮动件35未正常工作需要处理时,可以先从箱体31拆下过滤元件36,从安装孔303排掉第二腔Q2内的水,然后,通过按下杆体391使第二浮动件300下降,使得阻挡件301a不再封堵第一通孔301h,从而可以排出第一腔Q1内的水,阻挡件301a翘起的同时,还可以触碰第一浮动件35,解除其故障状态。最终,整个水箱30内恢复无水状态。可以理解的是,还可以通过其他方式实现对第一浮动件35的触碰来解除其故障状态,例如,利用工具从安装孔303伸入将第一浮动件35顶起。
图16~19示出的是连接件301b与箱体31转动连接的情形,可以理解的是,本申请实施例不限于此。例如,如图20所示,在另一种实施方式中,第二浮动件300与箱体31滑动配合,在浮动件300上浮过程中受到箱体31的横向限位,连接件301b、阻挡件301a与浮动件300的运动方向一致,在第二浮动件300上浮过程中,第二浮动件300通过连接件301b带动阻挡件301a上升而朝向第一通孔301h移动。该实施方式中,隔离板301仍包括侧板3011和挡板3012,挡板3012朝向出水口33所在侧延伸,连接件301b一端连接浮动件300,另一端朝出水口33所在侧延伸形成L状构造,挡板3012与箱体31底部之间的间距可供阻挡件301a竖直移动。在第二浮动件300上升过程中,阻挡件301a在连接件301b的带动下随之上升,并朝向第一通孔301h移动,当箱体31内液位到达第二预设高度H2时,阻挡件301a在浮力作用下堵住第一通孔301h。
示例性地,箱体31具有沿其高度方向延伸的第二导向件302,第二浮动件300活动地套设于第二导向件302上,以在浮力作用下沿第二导向件302移动。第二导向件302的数量可以不止一个,多个第二导向件302可以间隔 地设置,共同实现对第二浮动件300的导向作用,从而实现浮动件300与箱体31的滑动配合。
又例如,如图21所示,在又一种实施方式中,隔离板301和第一通孔301h都可以省略,第二开关组件可用于在箱体31内的液位达到第二预设高度H2时,切断出水管37和出水口33之间的液流通道,例如,第二开关组件通过封堵出水管37的末端使出水口33无法供液。示例性地,阻挡件301a与上方的出水管37的末端正对,在第二浮动件300上浮过程中,第二浮动件300通过连接件301b带动阻挡件301a上升而朝向出水管37的末端移动。当箱体31内液位到达第二预设高度H2时,阻挡件301a在浮力作用下堵住出水管37的末端,也能实现出水口33不再供液,防止箱体31内的水溢出。
在目前基站的清水箱补水控制的相关技术中,都是采用电信号进行控制的阀体(例如电磁阀)设置在清水箱与水源接头(例如自来水接头)之间的连接水管上,通过电信号控制阀的打开和关闭,且为了使连接水管在阀关闭时不承受高水压,阀体通常设置在邻近水源接头的位置。上述这种方案,由于阀体是由基站的电信号控制的,基站需要引出控制线连接到阀体或通过无线控制阀体,增加了成本,并且在安装基站时,可能需要额外对控制线的进行布线和防护设计,安装更复杂,增加了基站的安装难度。
本申请发明人针对上述相关技术的痛点,发明人经创造性劳动发现,上述痛点可利用基站自身的结构特点进行去电设计,得到一种去电设计的阀体方案,即控制阀,本申请提出的控制阀方案能够降低成本,且简化基站安装,降低安装难度的控制阀的技术方案。
本申请提出的控制阀,主要应用于基站水路系统,取代现有基站水路系统的水源端的电磁阀。
结合参阅图22和图23,或结合参阅图26至图28,本申请的控制阀包括阀体10、阀芯20和复位装置30;其中,阀体10设有进水孔11、出水孔12和内腔13,阀芯20活动设于阀体10的内腔13,复位装置30设于阀体10的内腔13;出水孔12连通内腔13位于阀芯20的第一侧A1的腔体部分;
在阀芯20的第一侧A1的总受力低于阀芯20的第二侧A2的总受力时,阀芯20朝向阀芯20的第一侧A1移动并向复位装置30施力,使进水孔11与出水孔12连通,即使控制阀打开;在阀芯20的第一侧A1的总受力不低于阀芯20的第二侧A2的总受力时,阀芯20在复位装置30的恢复带动下复位,使进水孔11与出水孔12不连通,即使控制阀关闭;其中,阀芯20的第一侧A1和第二侧A2为阀芯20的相对两侧。
下面以控制阀应用在基站水路系统为例,对本申请实施例的控制阀的工作原理进行说明。参考图29,控制阀应用在基站水路系统中时,控制阀300的进水孔11连接水源,控制阀300的出水孔12连接基站的清水箱100;该基站水路系统中的控制阀300的工作原理为:
1、当清水箱100需要进行补水时,控制基站的气泵装置200向清水箱100 抽负压,清水箱100则经控制阀300的出水孔12向内腔13位于阀芯20的第一侧A1的腔体部分抽气,使阀芯20的第一侧A1的气压下降,此时阀芯20的第二侧A2的总受力(包括:阀芯20的第二侧A2的气压和/或水压、和/或阀芯20的重力等的总受力)可以克服阀芯20的第一侧A1的总受力(包括:阀芯20的第一侧A1的气压和/或水压、和/或复位装置30的恢复力、和/或阀芯20的恢复力、和/或阀芯20向第一侧A1运动时的摩擦力等的总受力),也即阀芯20的第一侧A1的总受力低于阀芯20的第二侧A2的总受力,阀芯20朝向阀芯20的第一侧A1(即总受力低的一侧)移动,同时复位装置30被施力,使控制阀300的进水孔11与出水孔12连通,即驱动控制阀300打开,此时,水源的水则依次经控制阀300进水孔11、出水孔12流入到清水箱100中,实现给清水箱100补水;
2、当清水箱100补水完成或不需要补水时,可以控制气泵装置200停止给清水箱100抽负压,清水箱100不再经控制阀300的出水孔12向内腔13位于阀芯20的第一侧A1的腔体部分抽气,此时阀芯20的第二侧A2的水在流入阀芯20的第一侧A1的过程中使得阀芯20的第一侧A1的总受力逐渐升高,同时阀芯20在复位装置30的恢复带动下逐渐朝向阀芯20的第二侧A2移动复位,当阀芯20的第一侧A1的总受力(包括:阀芯20的第一侧A1的气压和/或水压、和/或复位装置30的恢复力、和/或阀芯20的恢复力等的总受力)恢复至不低于阀芯20的第二侧A2的总受力(包括:阀芯20的第二侧A2的气压和/或水压、阀芯20的重力、和/或阀芯20向第二侧A2运动时的摩擦力等的总受力)时,阀芯20在复位装置30的恢复带动下完全复位,使进水孔11与出水孔12不连通,即控制阀300自恢复至关闭状态,使清水箱100与水源之间的水路断开。
当然,本申请实施例的控制阀300还可以应用于其它水路系统场景。
本实施例的控制阀300,通过向控制阀300的出水孔12抽气的方式驱动控制阀300打开,以及通过复位装置30的带动实现控制阀300的自恢复关闭,如此,将该控制阀300应用在基站水路系统中作为控制清水箱100与水源接头通断的阀时,通过基站的气泵装置200经清水箱100与控制阀300的出水孔12之间的连接管路,向控制阀300抽负压即可控制控制阀300打开,且让气泵装置200停止抽负压,即可使控制阀300自恢复关闭,无需电信号控制;相较于现有技术而言,省去了基站引出的控制线,降低了成本,省去了控制线的布线和防护等安装操作,简化了基站的安装步骤,降低了安装难度。
在一些实施例中,复位装置30包括弹性件(例如弹簧、弹性胶块等),弹性件设于内腔13中,弹性件的一端连接于内腔13的内壁、另一端连接于阀芯20。

本申请发明人在实现提供一种通过气源对水箱供气施压以喷清水的实施方案的过程中,发现一般基站所配备的清水箱的容量一般都比较大,若通过气源输入气体至该大的清水箱内,会使得水箱的出水量和/或出水速率不易控制。尤其针对基站清洁拖擦件的场景中,通常希望可以对喷水量和/或喷水速率较为可控。
参照图35a、图35b和图36,本申请实施例提出的清洁基站,包括:
基站本体,设有清洗系统,清洗系统被配置为对待清洁件进行清洗;
缓存箱100,与基站本体连接,缓存箱100设有进水口101、出水口102和气口103,进水口101与水源连通,出水口102与清洁基站的清洗系统连通,以能够向清洗系统供液;
气源系统,与缓存箱100通过气口103连通,用于向缓存箱100内供气以施加正压,以使缓存箱100内的液体通过出水口102喷出;
缓存箱100的容积小于或等于预设值,以使缓存箱100至少包括第一状态和第二状态;其中,在第一状态下,缓存箱100内的液体基本充满缓存箱100;清洗系统执行一次清洗任务,以使缓存箱100从第一状态切换至第二状态,在第二状态下,缓存箱100内的液体基本被排空。
本实施例所涉及的清洁基站为用于对清洁机器人进行护理的基站,护理类型如清洗护理等。具体地,清洁基站主要包括基站本体、缓存箱100和气源系统等结构组成,基站本体设有用于对待清洁件进行清洗的清洗系统,其中,待清洁件可以是清洁机器人或清洁基站的待清洁件,示例性的,清洁机器人的待清洁件可以是如滚刷、扫刷、行动轮、万向轮等,而清洁基站的待清洁件则可以是清洁基站上所设,用于清洗清洁机器人的清洗槽等,清洗系统可以朝向基站的清洗槽喷水,以对清洗槽进行清洗。其中,清洗系统可以采用喷头组件与水管的结构组成,根据实际情况设置。
缓存箱100与基站本体连接,可选地,缓存箱100可拆卸地设置在基站本体上,连接方式可采用卡扣连接、螺丝连接等多种。并且,缓存箱100可以设置在基站本体的内部或外部,对此不作限制。其中,缓存箱100的进水口101与水源连通,出水口102与清洗系统连通,气口103与气源系统连通。缓存箱100用于缓存清洗系统的清洗用水,并在清洗系统执行清洗任务时向其供液。具体地,清洗系统需要执行清洗任务时,水源的水经进水口101进入缓存箱100内以进行缓存,并在缓存完成后,气源系统向缓存箱100内供气以施加正压,缓存箱100内的液体在气压的作用下通过出水口102喷出,以为清洗系统供液。其中,如图35a所示,可以是基站内部设置储水箱,通过储水箱供水作为水源,如图35b所示,也可以是以基站外部的水龙头、供水管路等供水作为水源,本领域技术人员可以根据实际情况设置。可选地,气源系统包括气泵,气泵的出气端与缓存箱100的气口103之间设置气流管路,以向缓存箱100供气。
进一步地,缓存箱100的容积小于或等于预设值,以使缓存箱100至少包括第一状态和第二状态,其中,该预设值根据实际情况设置,比如300ml。可以设计缓存箱100的容积为200ml~300ml之间,在一个具体实施例中,缓存箱100的容积为250ml。
在第一状态下,缓存箱100内的液体基本充满缓存箱100,所述的基本充满即可以是全部充满,也可以是差一点充满,在本申请实施例中,定义“基本充满”是指箱内液体离充满的误差可以为50ml以内,例如,当缓存箱100的容积为250ml时,箱内的液体的体积大于等于200ml时,均可认为是基本充满缓存箱100。在第二状态下,缓存箱100内的液体基本被排空,所述的基本被排空即可以是全部被排空,也可以是差一点被排空,存在些许余留,在本申请实施例中,基本被排空是指箱内液体离排空的误差在20ml以内,例如,当缓存箱100的容积为250ml时,在第二状态下,箱内的剩余液体的体积小于或等于20ml时,均可认为缓存箱100内的液体基本被排空。清洗系统执行一次清洗任务之后,缓存箱100从第一状态切换至第二状态。并且,清洗系 统相应进行了一次进水和喷水。其中,本申请实施例中所描述的一次清洗任务是指一次喷水预设时长所对应的喷水任务,该预设时长根据实际情况设置。例如,当需要对即缓存箱100每次缓存清洗系统一次清洗任务的用水量,清洗系统执行一次清洗任务之后,缓存箱100内的液体被排空。
本申请实施例提供的清洁基站,通过气动方式控制水箱内的清洗用水喷出,气动驱动的方式,可使得水不过泵,不易对泵造成卡滞。并且,本申请的缓存箱100缓存基站本体上清洗系统的清洗用水,缓存箱100的容积小于或等于预设值,基站本体的清洗系统执行一次清洗任务时,缓存箱100由箱内液体基本充满的第一状态切换至箱内液体基本排空的第二状态,即通过小容积的缓存箱100缓存一次清洗任务的用水,气源系统向容积较小的缓存箱100内供气以施加正压时,相较于对大水箱内供气施加正压,容积较小的水箱更容易控制出水量和出水速率,从而使得清洁喷水易于控制。
另外,缓存箱100的容积可以根据气源系统的气泵流量来大致确定,若缓存箱100的容积过大,则与气泵的流量不匹配。在一些实施例中,发明人经过实验验证发现,缓存箱100的容积在200ml~300ml之间,能够使得较好地匹配气泵的流量的同时,也能够使得喷水速率较快,喷水较为可控。
在一些实施例中,参照图35a、图35b和图36,气源系统还用于通过气口103从缓存箱100内抽气以在缓存箱100内形成负压,以使水源通过进水口101向缓存箱100供液。
本实施例中,清洗系统执行清洗任务时,气源系统通过气口103从缓存箱100内抽气,以在缓存箱100内形成负压,在此负压作用下,水源通过进水口101向缓存箱100供液。可选地,气源系统包括气泵,气泵的出气端和进气端可通过气流管路与缓存箱100的气口103连通,并可在气流管路中设置气路切换组件,如换气阀。通过气路切换组件进行气路切换,气源系统可通过气口103向缓存箱100内供气以施加正压或从缓存箱100内抽气以形成负压。
在一些实施例中,参照图37至图40,缓存箱100设有封堵组件10,封堵组件10包括封堵气口103的封堵状态,以及脱离气口103的打开状态;
其中,当缓存箱100内的液位小于预设极限液位值时,封堵组件10处于打开状态;当缓存箱100内的液位大于或等于预设极限液位值时,封堵组件10处于封堵状态。
缓存箱100内的液位小于预设极限液位值时,封堵组件10脱离气口103,处于打开状态。在打开状态下,气源系统可通过气口103向缓存箱100内供气以施加正压排液或从缓存箱100内抽气形成负压进液。缓存箱100内的液位大于或等于预设极限液位值时,封堵组件10封堵气口103,处于封堵状态。在封堵状态下,气源系统不能通过气口103从缓存箱100内抽气,缓存箱100不可进液,并且,缓存箱100内的液体不会经过气口103进入气路中,有利于保护气源(如气泵)。
在一些实施例中,参照图37至图40,封堵组件10可以包括:

其中,缓存箱100中的液位上升时,浮动件11上浮以带动封堵件12朝向气口103移动;缓存箱100中的液位下降时,浮动件11下落以带动封堵件12远离气口103移动。
本实施例中,封堵组件10包括浮动件11和封堵件12的结构组成,封堵件12与气口103相适配,用于封堵或打开气口103。浮动件11用于随缓存箱100中的液位升降,进而带动封堵件12上下移动。浮动件11的外形构造与材质不作限定,根据实际情况设置。可选地,气口103位于缓存箱100的上部,封堵件12位于浮动件11的上端且朝向气口103。
气源系统通过气口103从缓存箱100内抽气时,缓存箱100内形成负压,在此负压作用下,水源通过进水口101向缓存箱100供液,缓存箱100中的液位逐渐上升,进而使得浮动件11上浮以带动封堵件12朝向气口103移动,当缓存箱100内的液体基本充满缓存箱100时,封堵件12上升至自动封堵气口103。
气源系统通过气口103向缓存箱100内供气时,缓存箱100内形成正压,在此正压作用下,缓存箱100内的液体通过出水口102排出,缓存箱100中的液位逐渐下降,进而使得浮动件11下落以带动封堵件12远离气口103移动。
在一些实施例中,参照图37至图40,还可以包括:

在一些实施例中,参照图36至图38,缓存箱100可以设有安装部110,安装部110形成有安装腔110a,封堵组件10位于安装腔110a中,且浮动件11的侧壁与安装腔110a的腔壁配合,安装腔110a的一端与缓存箱100的内腔连通,另一端与气口103连通。

当然,承接件200与安装部110可以为一体成型,或者分体成型并固定在一起,承接件200可以位于安装部110下方,以使得封堵组件10在承接件200与安装部110围成的空间内运动。

为实现缓存箱100正常进液和排液,出水口102和进水口101处分别设置开关部件,具体为出水口102处设有第一开关部件1,进水口101处设有第二开关部件2。缓存箱100呈负压状态时,第一开关部件1呈关闭状态,出水口102截断,第二开关部件2呈打开状态,进水口101导通,在负压作用下,水源的水通过进水口101进入缓存箱100内。缓存箱100呈正压状态时,第 一开关部件1呈打开状态,出水口102导通,第二开关部件2呈关闭状态,进水口101关闭,在正压作用下,缓存箱100内的液体通过出水口102排出。

本申请还提出一种清洁系统,包括前述实施例记载的清洁基站以及清洁机器人,清洁基站用于对清洁机器人进行护理。该清洁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。
本申请实施例提出的基站水路系统,主要应用于清洁设备的基站,其中清洁设备可以是移动式主动清洁设备(例如,清洁机器人)、手持式被动清洁设备(例如,手持洗地机、手持拖把),或其它类型的清洁设备。
参照图42,在本实施例中,该基站水路系统包括气源系统100、供水装置30和污水回收装置40;供水装置30具有第一气口和出水端D,供水装置30通过第一气口与气源系统100连通;污水回收装置40具有第二气口和进水端J,污水回收装置40通过第二气口与气源系统100连通。其中,气源系统100用于经第一气口给供水装置30注气以施加正压,进而将供水装置30内的液体通过出水端D排出;气源系统100还用于经第二气口给污水回收装置40抽气以施加负压,进而将外部污水(污水回收装置40外部的污水)经进水端J抽入污水回收装置40。
本实施例的基站水路系统在工作时,气源系统100可以单独给供水装置30施加正压,使供水装置30内的液体通过出水端D排出;气源系统100也可以单独给污水回收装置40施加负压,使污水回收装置40将外部污水从进水端J抽吸回收。
在一些实施例中,气源系统100还可以同时给供水装置30施加正压和给污水回收装置40施加负压,使供水装置30向外排液和污水回收装置40抽吸回收外部污水同时进行。
本实施例的基站水路系统应用于基站时,供水装置30的出水端D可以与基站的清洗区连通,和/或与给清洁设备加水的注水接口对接连通,和/或与清洁设备的污水箱对接连通;污水回收装置40的进水端J可以与基站的清洗区连通,和/或与给清洁设备抽污水的抽水接口连通;其中,清洁设备可以为清洁机器人、手持式洗地机等。
具体的,基于基站的供水装置30,本领域技术人员可以对基站和/或清洁设备进行具体设计,以使得可以满足以下应用需求:例如,基站的供水装置30通过出水端D提供清洁用水,在清洗区喷水以清洗清洁设备的拖擦件、行走轮等清洁设备上的待清洁件,和/或直接向清洗区喷水以清洁基站的清洗区,和/或向清洁设备的清水箱加水,甚至,基站的供水装置30的出水端D可以与清洁设备的污水箱对接连通,以实现向清洁设备的污水箱内喷水,进而清洁污水箱。在本申请实施例中基站可以通过控制气源系统100向供水装置30施加正压,供水装置30则进行排液,以向清洗区喷水,和/或向清洁设备的清水箱加水,和/或向清洁设备的污水箱喷水。
基于基站的污水回收装置40,本领域技术人员可以对基站和/或清洁设备进行具体设计,以使得可以满足以下应用需求:例如,基站回收清洗区的污水,和/或回收清洁设备的污水箱中收集的污水。基站可以通过控制气源系统100向污水回收装置40施加负压,污水回收装置40则将清洗区的污水和/或清洁设备的污水箱中收集的污水,抽吸回污水回收装置40中。
在一些实施例中,基站还可通过控制气源系统100同时向供水装置30施加正压和向污水回收装置40施加负压,使供水装置30向外喷水的同时,污水回收装置40抽吸回收清洁设备中收集的污水,或使供水装置30向清洁设备加水的同时,污水回收装置40抽吸回收清洗区的污水。如此,可以有效提高水路系统的水循环效率,可有效节约基站对清洁设备进行护理的时间。
另外,可通过设置一个阀单独控制清洁设备的注水接口与供水装置30的出水端D的通断,设置一个阀单独控制清洗区与供水装置30的出水端D的通断,设置一个阀单独控制清洁设备的抽水接口与污水回收装置40的进水端J的通断,以及设置一个阀单独控制清洗区与污水回收装置40的进水端J的通断。
另外,值得注意的是,为使得供水装置30的喷水量和/或喷水速率可控性更好,可以选用容积较小的供水装置30,示例性的,可以选用供水装置30的容积等于一次喷水量。具体的,供水装置30的容积可以为200ml-300ml。
本实施例的基站水路系统的技术方案,采用气源系统100与供水装置30的第一气口和污水回收装置40的第二气口连接,气源系统100通过向供水装置30施加正压,以控制供水装置30的排水,以及气源系统100通过向污水回收装置40施加负压,以控制污水回收装置40抽吸回收外部污水;因此, 使用本实施例基站水路系统的基站,无需额外安装水泵来单独控制供水装置30的排水,相较于现有基站同时采用气泵和水泵的方案而言,省去了水泵及其连接管路,简化了基站水路系统的结构,降低了基站的成本。
参阅图43,在一些实施例中,气源系统100可以包括气泵20和至少一个控制组件101,其中,控制组件101连接供水装置30和/或污水回收装置40,气泵20连接控制组件101,也就是,气泵20经控制组件101连接供水装置30和/或污水回收装置40。控制组件101用于控制气泵20与供水装置30之间气路的通断,即通过控制组件101控制气泵20向供水装置30注气的通断,从而控制气泵20是否向供水装置30施加正压。及/或,控制组件101用于控制气泵20与污水回收装置40之间气路的通断;即通过控制组件101控制气泵20向污水回收装置40的抽气的通断,从而控制气泵20是否向供水装置30施加负压。
在图43中,仅是以气源系统100包括一个控制组件101为例。当然,在其他实施例中,气源系统100还可以是包括多个控制组件101,例如,气泵经一个控制组件101连接供水装置30,以及经另一个控制组件101连接污水回收装置40,一个控制组件101控制气泵向供水装置30注气的通断,从而控制气泵是否向供水装置30施加正压,另一个控制组件101控制气泵向污水回收装置40的抽气的通断,从而控制气泵是否向供水装置30施加负压。
参阅图44,在一些实施例中,控制组件101包括换向阀10和与换向阀10电连接的控制器50,换向阀10设有抽气口11、注气口12、至少两个外接气口、与注气口12保持连通的注气通道,以及与抽气口11保持连通的抽气通道;注气通道和抽气通道分别连接一个外接气口C,其中,至少两个外接气口包括第一外接气口13和第二外接气口14;气泵20的进气口21与换向阀10的抽气口11连通,气泵20的出气口22与换向阀10的注气口12连通,供水装置30与第一外接气口13连接,污水回收装置40与第二外接气口14连接;控制器50用于控制注气通道和/或抽气通道切换连接不同的外接气口C。一般而言,换向阀10可以包括阀芯和阀座,阀芯可运动地设于阀座中,注气通道和抽气通道可以设于阀芯,或者至少部分形成于阀芯,阀芯相对于阀座运动以使得注气通道和/或抽气通道连通不同的外接气口C,本申请实施例所提供的换向阀10的结构形态不受限定,本领域技术人员可以根据需要具体设计。
需要说明的是,在本申请实施例中,控制器50可以为旋转动力驱动装置或者直线动力驱动装置,例如可以为旋转电机或者直线电机。对应的,阀芯的运动方式可以为转动或直线移动。
下面给出一些实施例对换向阀10的具体结构进行描述,如图50-图54所示,换向阀10可以包括阀芯110和阀座120,阀芯110的周壁设有两个通孔111,阀座120可以设有外接气口,抽气通道13a和注气通道14a各自通过形成于阀芯110的周壁的通孔111与外接气口连通。可选地,注气口12与抽气口11之间的夹角和第一外接气口13和第二外接气口14之间的夹角可以相同, 以使得阀芯110在旋转该夹角的角度后,可以将与抽气通道13a和注气通道14a连通的外接气口C对调,以实现在同时进清水和排污水,以及同时喷清水和抽污水的两种模式下切换。
下面对具体实现方式进行详细描述,在阀芯110切换位置之前,抽气通道13a与第一外接气口13连通,注气通道14a与第二外接气口14连通,气流的流经路径为:供水装置30→第一外接气口13→抽气通道13a→抽气口11→气泵20的进气口21→气泵20的出气口22→注气口12→注气通道14a→第二外接气口14→污水回收装置40,实现给供水装置30抽负压,给污水回收装置40加正压,进而实现同时进清水和排污水。在阀芯110运动一定角度后,抽气通道13a与第二外接气口14连通,注气通道14a与第一外接气口13连通,气流的流经路径为:污水回收装置40→第二外接气口14→抽气通道13a→抽气口11→气泵20的进气口21→气泵20的出气口22→注气口12→注气通道14a→第一外接气口13→供水装置30,实现给供水装置30加正压,给污水回收装置40抽负压,进而实现同时喷清水和抽污水。
本实施例中,控制组件101的控制工作原理为:气泵20保持从换向阀10的抽气通道抽气,及保持向换向阀10的注气通道注气,控制器50通过控制换向阀10切换,可使换向阀10的抽气通道和/或抽气通道在不同的外接气口C之间切换;当控制器50控制换向阀10切换到注气通道与第一外接气口13连通时,气泵20的出气口21则与供水装置30连通,实现给供水装置30注气以施加正压;当控制器50控制换向阀10切换到抽气通道与第二外接气口14连通时,气泵20的进气口22则与污水回收装置40连通,实现给污水回收装置40抽气以施加负压。
本实施例中,当换向阀10的外接气口仅为两个时,即换向阀10的外接气口仅包括第一外接气口13和第二外接气口14时,则换向阀10的注气通道和抽气通道分别对应连接第一外接气口13和第二外接气口14,则控制器50可以用于控制注气通道和抽气通道互换连接的外接气口C。此时,则气泵20同时向供水装置30施加正压和向污水回收装置40施加负压,或气泵20同时向供水装置30施加负压和向污水回收装置40施加正压。
当换向阀10的外接气口数量大于两个时(例如3个、4个、5个或更多),在本申请实施例中,外接气口C的数量可以优选为偶数个,且两两成对设置。一些外接气口C用于连接用气部件,例如污水回收装置40、供水装置30、清洁液供液装置60等,另一些外接气口C可以用于与大气连通。控制器50控制注气通道和/或抽气通道切换连接不同的外接气口C时,注气通道和/或抽气通道则可切换连接到除第一外接气口13和第二外接气口14外的其它连接至大气的外接气口C,使气泵20可实现单独给供水装置30施加正压,及/或,气泵20单独给污水回收装置40施加负压。
例如,参阅图45a-45c,在一些实施例中,换向阀10的至少两个外接气口还包括至少一个与外界大气连通的第三外接气口15。通过换向阀10增加与外接空气连通的第三外接气口15,从而控制器50还可以控制换向阀10的抽 气通道和/或注气通道切换到与第三外接气口15连接,增加基站水路系统的工作模式,例如可实现使气泵20可实现单独给供水装置30施加正压,及/或,气泵20单独给污水回收装置40施加负压。从而满足基站更多不同的工作场景需求。
示例性的,一对外接气口C中一个与用气部件连通、另一个与大气连通,此时,可实现对于单个用气部件的抽进或排出气体,其中,用气部件包括但不限于以下至少一种:供水装置30、污水回收箱40、清洁液供液装置60。
需要说明的是,图44中仅示出控制组件101包括一个换向阀10的实施例。当然,在其他一些实施例中,控制组件101还可以为包括多个换向阀10的方案,例如,气泵20经一个换向阀10连接供水装置30,以及经另一个换向阀10连接污水回收装置40,一个换向阀10使气泵20的出气口21在与供水装置30连通和与大气连通之间切换,从而控制气泵20是否向供水装置30施加正压,另一个换向阀10使气泵20的进气口22在与污水回收装置40连通和与大气连通之间切换,从而控制气泵20是否向供水装置30施加负压。在其他一些实施例中,控制组件101还可以为包括多个电磁阀的方案,例如,污水回收装置40单独仅一个电磁阀连接气泵20的进气口21,气泵20的进气口21还单独经一个设有电磁阀的气管与大气相连,供水装置30单独仅一个电磁阀连接气泵20的出气口22,气泵20的出气口22还单独经一个设有电磁阀的气管与大气相连。
在一些实施例中,可以通过对控制器50控制逻辑的预先设置,可使换向阀10仅在两种状态之间切换;其中一种状态为:注气通道连接第一外接气口13,抽气通道连接第二外接气口14,使供水装置30内为正压状态,及污水回收装置40内为负压状态;另一种状态为:注气通道连接第二外接气口14,抽气通道连接第一外接气口13,使供水装置30内为负压状态,及污水回收装置40内为正压状态。如此,可使基站水路系统的气泵20始终保持同时对供水装置30和污水回收装置40分别正压和负压,同时驱动供水装置30和污水回收装置40工作,这样可以降低气泵20启动工作的时长。具体的,气泵20向供水装置30施加正压及向污水回收装置40施加负压时,供水装置30向外排水,同时污水回收装置40抽吸外部污水;气泵20向供水装置30施加负压及向污水回收装置40施加正压时,可使与供水装置30连通的水源向供水装置30补水,同时污水回收装置40可通过排水端将其储存的污水排出到地漏或排污管道。
参阅图45a~图45c,在一些实施例中,供水装置30包括第一清水箱311,第一清水箱311连接第一进水管312和第一出水管313。其中,第一清水箱311设有与第一外接气口13连接的第一通气口A1,第一进水管312的第一端连接第一清水箱311,第一进水管312的第二端用于连接至水源。第一进水管312上可以设有由其第二端向其第一端单向导通的第一单向阀314;第一出水管313的第一端连接第一清水箱311,第二端用于向外供水,第一出水管313上设有由其第一端向其第二端单向导通的第二单向阀315。
其中,第一清水箱311的容量可以明显大于基站每次给清洁设备护理所需的水量,其中,基站给清洁设备护理可以包括:向清洗区喷水以清洗清洁设备的拖擦件,或给清洁设备的水箱加。第一清水箱311也可以是容量较小的一个容器,例如容量大致等于每次给清洁设备护理所需的水量。
本实施例的基站水路系统,在气泵20经第一通气口A1向第一清水箱311内注气时,由于第一单向阀314阻止了第一清水箱311经第一进水管312向水源排气,因此,第一清水箱311中的气压会升高(即向第一清水箱311施加正压),进而会使第一清水箱311可经第一出水管313向外排水,实现控制第一清水箱311向清洗区喷水,或向清洁设备的清水箱内喷水,或向清洁设备的污水箱内喷水;在气泵20经第一通气口A1向第一清水箱311抽气时,由于第二单向阀315阻止了空气从第一出水管313进入第一清水箱311内,因此,第一清水箱311中的气压会降低(即向第一清水箱311施加负压),进而会使水源端的水经过第一进水管312被抽到第一清水箱311中,实现控制第一清水箱311自动补水。需要说明的是,此处所描述的“水源”是指该第一清水箱311外部的水源,例如可以为基站外部的水源(例如市政水源:如水龙头),也可以为设于基站内部的另一个储水容器。特别的,当第一清水箱311采用抽负压的方式进水,且第一进水管312连接至市政水源时,可以在第一进水管312的管路上设置储水容器或其他减压截止模块,使得第一清水箱311抽负压进入的液体为储水容器中的液体,而市政水源的水不会在自然水压的作用下进入第一清水箱311,也就是说,第一清水箱311的进水动力仅依赖于气源系统抽负压,由此可提高系统可控性,且降低第一进水管312的爆裂风险。
在一些具体实施例中,参阅图49,基站水路系统还可以包括减压装置,减压装置的一端连接外部水源,减压装置的另一端连接供水装置30,减压装置用于将外部水源的市政水压减压,使到达供水装置30的水压较低。其中,减压装置可以是减压阀,也可以是减压水路系统,或其它类型的减压结构。本实施例的基站水路系统,通过在供水装置30与水源之间增设减压装置,降低基站水路系统中的水管的压力,有效避免了水管由于水压过高而出现爆管的情况发生。
在一些实施例中,减压装置包括储水容器80;储水容器80设有第二进水口81和第二出水口82,第二进水口81用于连接外部水源,第二出水口82连接供水装置30,且第二出水口82向供水装置30单向导通;储水容器80内设有第二浮球阀83,用于在储水容器80内的水位上升到设定高度时关闭第二进水口81,以及在储水容器80内的水位低于设定高度时打开第二进水口81。
本实施例减压装置采用一个储水容器80来进行减压,通过外部水源自动向储水容器80供水,在外部水源的高压水进入储水容器80中后压力被泄放,然后再从第二出水口82供给供水装置30,实现降低供水装置30的进水水压。当储水容器80中的水位达到设定高度时,第二浮球阀83会关闭第二进水口81,避免储水容器80水位过满而造成溢出。
参阅图49,在一些实施例中,储水容器80内设有第三出水管84,第二出水口82设于储水容器80的顶端,第三出水管84的一端与第二出水口82连通,第三出水管84的另一端延伸至储水容器80的底端;第三出水管84上设置有断虹吸结构85,或第二出水口82与供水装置30连接的管路上设有断虹吸结构85。示例性的,断虹吸结构85可以为鸭嘴阀。
本实施例中,在给供水装置30加水时,气泵20通过换向阀10给供水装置30施加负压(例如给第一清水箱311施加负压),供水装置30通过第三出水管84将储水容器80中的水抽吸到供水装置30,在加水完成后,控制换向阀10切换使气泵20停止给供水装置30施加负压,此时,断虹吸结构85会将储水容器80向供水装置30输送的水路断开,有效防止储水容器80与供水装置30之间的连接管路出现泄漏时,储水容器80中的水不断从漏水处泄漏,而将室内淹没。
在一些实施例中,储水容器80可以设置在基站外部,例如,将储水容器80设置在外部水源处,这样,可以大幅缩短储水容器80与外部水源之间的高压水管的长度,降低外部水源与储水容器80之间的高压水管由于水压过高而爆管的情况发生。
参阅图46,在一些实施例中,第一出水管313设有第一清洁液接口B,第一清洁液接口B用于连接清洁液供液装置60,以接收清洁液供液装置60提供的清洁液,第二单向阀315可以位于第一出水管313的第一端与第一清洁液接口B之间,即第一清洁液接口B设置在第一出水管313的第二端与第二单向阀315之间的管段上。
在气泵20向第一清水箱311内施加正压,使第一清水箱311经第一出水管313向外排水时,清洁液供液装置60可经第一清洁液接口B向第一出水管313中添加清洁液,以使清洁液与第一清水箱311排出的水混合,实现基站水路系统的自动添加和混合清洁液。本实施例中,清洁液供液装置60的清洁液提供的动力可以为蠕动泵或者本申请实施例所提供的气源系统。
另外,由于第二单向阀315设置在第一出水管313的第一端与第一清洁液接口B之间,因此,在气泵20向第一清水箱311内施加负压时,第二单向阀315阻断了第一清洁液接口B与第一清水箱311的气路连通,可防止清洁液供液装置60的清洁液被抽入到第一清水箱311中。在一些实施例中,第一清洁液接口B可以靠近第二单向阀315设置,这样加入第一出水管313中的清洁液,能更充分的在第一出水管313中与水混合均匀。
在一些实施例中,第一清水箱311内可以设有第一浮球阀,用于在第一清水箱311的水位上升到设定高度时关闭第一进水管312的第一端或第一通气口A1,以及在第一清水箱311的水位低于设定高度时打开第一进水管312的第一端或第一通气口A1。通过设置第一浮球阀,在第一清水箱311的水位达到设定高度(预警水位高度),第一浮球阀会关闭掉第一进水管312的第一端或关闭掉第一通气口A1,使第一清水箱311停止进水,如此,防止第一清水箱311补水时,将第一清水箱311加的过满而出现部分水从第一通气口A1 溢出到换向阀10或气泵20中,进而损坏换向阀10或气泵20的情况发生,保证了换向阀10和气泵20的安全。当然,在一些实施例中,第一浮球阀也可以采用相同功能作用的防溢结构或组件(例如防溢针)替换。
值得注意的是,图示中第一清水箱311的第一进水管312位于第一清水箱311的上部,第一出水管313位于第一清水箱311的下部,但本申请并不以此为限,在其他一些实施例中,第一进水管312可以位于第一清水箱311的下部,第一出水管313可以位于第一清水箱311的上部,或者,第一进水管312和第一出水管313均位于第一清水箱311的上部,或者,第一进水管312和第一出水管313均位于第一清水箱311的下部。
参阅图48,在一些实施例中,供水装置30包括第二清水箱316、清水缓存箱317、第二进水管318和第二出水管319;清水缓存箱317设有第二通气口A2,第二通气口A2经设有阻液结构322的管路连接第一外接气口13;第二清水箱316经第二进水管318连接清水缓存箱317,第二进水管318上设有由第二清水箱316向清水缓存箱317单向导通的第三单向阀320;第二出水管319的第一端连接清水缓存箱317,第二端用于向外供水,第二出水管319上设有由第二出水管319的第一端向第二出水管319的第二端单向导通的第四单向阀321。本实施例中,气泵20控制清水缓存箱317排水和补水的原理与图46所示实施例中的原理相同,可参照图46所示实施例的原理,在此不再赘述。其中,阻液结构322可以用于在清水缓存箱317内的水位达到预设水位时,自动堵住清水缓存箱317与气源系统之间的气路,以阻碍清水缓存箱317内的液体进入气源系统100,特别的,阻碍液体进入气泵20而避免在一定程度上损坏气泵20。
本实施例基站水路系统的供水装置30,通过设置清水缓存箱317,清水缓存箱317的容量可设置成等于单次的喷水量,如此,基站水路系统每次喷水都是将清水缓存箱317排空,在每一次需要喷水时,只需控制气泵20向清水缓存箱317施加正压持续固定的时间(例如,8秒、10秒、15秒等),使清水缓存箱317中的水全部排完,这样精准的控制每次的喷水量相同。并且,清水缓存箱317每一次从第二清水箱316加水的量也是固定的,即加满清水缓存箱317,基站水路系统加水时也更好控制;由于清水缓存箱317的第二通气口A2与第一外接气口13连接的管路上设置有阻液结构322,可以保证清水缓存箱317中水不会经第二通气口A2溢出到换向阀10中,保证了气泵20给清水缓存箱317施加负压时的安全性。
在一些实施例中,第二清水箱316可以连接到外部水路中(例如,自来水水龙头),水龙头供水给第二清水箱316,第二清水箱316经第三单向阀320给清水缓存箱317加水。另外,在一些实施例中,供水装置30在有清水缓存箱317时,也可以不需要第二清水箱316,即清水缓存箱317直接与外部水路连接。
在一些实施例中,清水缓存箱317还设有第二清洁液接口,第二清洁液接口用于连接清洁液供液装置60,以接收清洁液供液装置60提供的清洁液。 由于在基站水路系统每一次喷水时,都会将清水缓存箱317中的水排空,不会有存留,因此,清洁液可以直接加到清水缓存箱317中,在清水缓存箱317中完成与清水的混合,如此,可以更好的保证清洁液混合均匀。
参阅图46、图48和图49,在一些实施例中,清洁液供液装置60和供水装置30均连接第一外接气口13,即清洁液供液装置60和供水装置30共用第一外接气口13,气泵20通过第一外接气口13可同时控制供水装置30和清洁液供液装置60的工作。如此,当气泵20通过第一外接气口13给供水装置30施加正压时,清洁液供液装置60也受到气泵20施加的正压,此时供液装置排水,同时清洁液供液装置60可向外排清洁液给供水装置30或其它装置(例如基站的清洗区),当气泵20通过第一外接气口13给供水装置30施加负压时,清洁液供液装置60也受到气泵20施加的负压,此时供液装置补水,同时清洁液供液装置60也可以进行清洁液补充。
参阅图47,在其他一些实施例中,换向阀10的至少两个外接气口还包括第四外接气口16,清洁液供液装置60连接第四外接气口16,即清洁液供液装置60由单独的一气路控制工作。气泵20通过第四外接气口16给清洁液供液装置60施加正压时,清洁液供液装置60排清洁液,气泵20通过第四外接气口16给清洁液供液装置60施加负压时,清洁液供液装置60可从清洁液源处补充清洁液。
在一些实施例中,清洁液供液装置60包括清洁液主容器61(作为清洁液源)和清洁液缓存容器62,清洁液主容器61设有出液口,清洁液缓存容器62设有进液口、排液口和第三通气口A3;清洁液主容器61的出液口经第五单向阀63单向连通清洁液缓存容器62的进液口,清洁液缓存容器62的排液口经第六单向阀64单向连接供水装置30,第三通气口A3连接第一外接气口13(参考图46、图48和图49)或第四外接气口16(参考图47)。
本实施例中,清洁液供液装置60的工作方式为:气泵20通过第一外接气口13或第四外接气口16给清洁液缓存容器62施加正压时,清洁液缓存容器62通过其排液口排清洁液,气泵20通过第一外接气口13或第四外接气口16给清洁液缓存容器62施加负压时,清洁液缓存容器62通过其进液口从清洁液主容器61抽吸清洁液,通过设置的第五单向阀63,可在清洁液缓存容器62排清洁液时,阻碍清洁液缓存容器62中的清洁液回到清洁液主容器61中;通过设置的第六单向阀64,可在清洁液缓存容器62从清洁液主容器61抽吸清洁液时,阻碍供水装置30中的液体从清洁液缓存容器62的排液口回流到清洁液缓存容器62中。在一些实施例中,清洁液缓存容器62可以是液囊式容器,也可以是活塞式容器。
在一些实施例中,清洁液供液装置60还可以包括用于调节气流速率的节流阀65,节流阀65串接在第三通气口A3与换向阀10的第一外接气口13或第四外接气口16之间。通过设置的节流阀65,使得在清洁液缓存容器62排清洁液和吸入清洁液时,可以通过调节节流阀65的节流截面或节流长度,也即调节气流速率,从而控制清洁液缓存容器62的排液速度和吸入清洁液的速 度,使清洁液排液时可以保持恒定的速度排出,更好的控制排出的清洁液与供水装置30喷水的均匀混合;并且,可以有效解决清洁液缓存容器62与供水装置30共用第一外接气口13时,清洁液缓存容器62排清洁液和供水装置30喷水所需气体量不同的矛盾。
上述实施例中,通过气泵20实现了气动控制清洁液供液装置60的排清洁液,使基站水路系统无需使用蠕动泵来控制排清洁液,省去了蠕动泵,进一步简化了基站水路系统的结构,降低了成本。
参阅图45a至图49,在一些实施例中,基站水路系统还包括底座槽70,底座槽70设有第一进水口71、第一出水口72,第一进水口71连接供水装置30,且供水装置30向第一进水口71单向导通,第一出水口72连接污水回收装置40,且第一出水口72向污水回收装置40单向导通。
基站水路系统还包括大气连接管路L,大气连接管路L的一端与第三外接气口15连接,另一端形成第四通气口A4,第四通气口A4朝向底座槽70。
本实施例的基站水路系统,由于将换气阀10的通大气口通过第四通气口A4与底座槽70连通,一方面使得通大气口不直接外露于基站,另外一方面由于若气泵20或气路通道有水汽进入,水汽可以直接滴落在底座槽70内,而不会到用户家里的地面或者墙面,有利于提高用户体验。
在具体使用时,在有清洁设备进入基站需要清洗护理时,先控制换向阀10切换至气泵20向供水装置30施加正压,大气经与底座槽70连通的第四通气口A4被抽入换向阀10内,然后气流至少经过第一外接气口13和第一通气口A1进入供水装置30,使得供水装置30可以通过第一进水口71喷水到底座槽70内,供清洁液设备清洗清洁件(拖擦件、滚刷、拖擦件等);在清洁设备的清洗完清洁件后,控制换向阀10切换至气泵20向污水回收装置40施加负压,污水回收装置40则通过底座槽70的第一出水口72将底座槽70内的污水抽吸到污水回收装置40中,在此过程中,换向阀10经第四通气口A4接大气,气流经过污水回收装置40再到换向阀10,再经过换向阀10的第五外接气口17到底座槽70的第四通气口A4,气流经第四通气口A4吹向底座槽70,扰动底座槽70内的气流,注气可在一定程度上提高清洁设备的清洁件(例如拖擦件)的干燥效率。
在一些实施例中,如图45a中所示换向阀10具有两个第三外接气口15,该两个第三外接气口15均与底座槽70连通。在一些实施例中,如图45b中所示换向阀10具有两个第三外接气口15,其中一个第三外接气口15直接朝向基站外部,另一个第三外接气口15与底座槽70连通。在一些实施例中,如图45c中所示换向阀10具有两个第三外接气口15,两个第三外接气口15均直接朝向基站外部。
需要说明的是,图46~图49中第三外接气口15的数量可以与换向阀10上接用气部件的外接气口C的数量相等,例如,图46、图48和图49中接用气部件的外接气口的数量为两个,具体为第一外接气口13、第二外接气口14,则对应的第三外接气口15的数量也为两个。图47中接用气部件的外接气口C 的数量为三个,具体为第一外接气口13、第二外接气口14、第四外接气口16,则对应的第三外接气口15的数量也为三个。
另外,图46~图49中第三外接气口15均通过大气连接管路L连通至底座槽70,在其他一些实施例中,其中一些第三外接气口15也可以连接至基站外部,或者所有第三外接气口15可以连接至基站外部。本申请实施例不做特别限定。
参阅图45a至图49,在一些实施例中,污水回收装置40包括污水箱41、抽水管42和排水管43,污水箱41设有与第二外接气口14连接的第五通气口A5;抽水管42的第一端连接污水箱41,抽水管42的第二端用于抽吸污水,抽水管42上设有由其第二端向其第一端单向导通的第七单向阀44;排水管43的第一端连接污水箱41,排水管43的第二端用于排污水,排水管43的第二端可连接到地漏或排污管道,排水管43上设有由其第一端向第二端单向导通的第八单向阀45。
本实施例的污水回收装置40的工作方式为:当气泵20通过第二外接气口14给污水箱41施加负压时,污水箱41通过抽水管42将外部污水抽吸到污水箱41中,当气泵20通过第二外接气口14给污水箱41施加正压时,污水箱41通过排水管43将污水箱41中的污水排出到地漏或排污管道。其中,污水箱41将外部污水抽吸至污水箱41的过程中,第八单向阀45闭合,防止污水箱41抽吸外部污水时排水管43进气,使得污水箱41内能保持负压状态,且该过程中污水不会从排水管43排出。在将污水箱41内的污水排出至外界的过程中,第七单向阀44闭合,防止污水箱41内的污水排出至外界时抽水管42进气,使得污水箱41内能保持正压状态,且该过程中污水箱41中的污水不会从抽水管42排出。
在一些实施例中,污水箱41内可以设有浮球阀,用于在污水箱41的水位上升到设定高度时关闭抽水管42的第一端或第五通气口A5,以及在污水箱41的水位低于设定高度时打开抽水管42的第一端或第五通气口A5。通过设置浮球阀,在污水箱41的水位达到设定高度(预警水位高度),浮球阀会关闭掉抽水管42的第一端或关闭掉第五通气口A5,使污水箱41停止抽吸污水,如此,防止污水箱41抽吸污水时,污水箱41过满而出现污水从第五通气口A5溢出到换向阀10或气泵20中,进而损坏换向阀10或气泵20的情况发生,保证了换向阀10和气泵20的安全。
当然,在一些实施例中,浮球阀也可以用相同功能作用的防溢结构或组件替换。例如,污水箱41内可以设有导电电极,导电电极可以连接有控制装置,控制装置可以与气泵20或者换向阀10连接,以用于在导电电极被触发时,控制装置控制气泵20和/或换向阀10停止给污水箱41抽负压的工作。具体而言,导电电极的位置可以设置较高,示例性的,可以设于污水箱41的顶部,使得污水箱41内的水位达到设定高度(预警水位高度)时,导电电极接触到污水而电导通,此时与导电电极电连接的控制装置控制气泵20或者换向阀10停止给污水箱41抽负压的工作,从而使得污水箱41内不再进污水,达 到水满自停的目的。
需要说明的是,本申请实施例中所提及的第一单向阀314、第二单向阀315、第三单向阀320、第四单向阀321、第五单向阀63、第六单向阀64、第七单向阀44、第八单向阀45均可以为鸭嘴阀。

请参阅图55和图56,本申请实施方式提供了一种液体缓存结构100,液体缓存结构100包括座体110和弹性容器120,座体110设有收容腔111、第一开口112和第二开口113,收容腔111分别与第一开口112、第二开口113连通,弹性容器120收容在收容腔111内并与收容腔111相隔离,弹性容器120用于通过第一开口112连通传输管200的缓存进液口211和缓存出液口221,在通过第二开口113从收容腔111抽出填充介质时,弹性容器120扩张以从缓存进液口211吸入液体,在通过第二开口113向收容腔111注入填充介质时,弹性容器120收缩以从缓存出液口221排出液体。
具体地,液体可以是清洁液、清水、污水中的任意一种,在本申请实施例中,以液体为清洁液为例进行说明。弹性容器120可以包括软囊,软囊可以呈褶皱状,也可呈气球状,便于张开和收缩。在通过第二开口113从收容腔111抽出填充介质时,弹性容器120因抽出填充介质时产生的作用力而进行扩张,这时缓存进液口211处于打开的状态,液体通过缓存进液口211进入弹性容器120中;在通过第二开口113向收容腔内注入填充介质时,弹性容器120由注入填充介质时产生的压力而处于收缩的状态,液体经缓存出液口221排出。填充介质可以为气体或者液体,在一个实施例中,填充介质例如为空气,可以通过气泵抽出或注入空气。
因为活塞的原理决定了活塞必须与座体的内侧壁密封抵接。因为清洁液的存在,润滑容易失效,一旦活塞与座体的内侧壁卡涩,则运动不畅。但是弹性容器120由于本身与收容腔111是隔绝的,其工作原理决定了弹性容器120无需与座体110的内侧壁密封抵接,因此也不存在与座体110的内侧壁卡涩的问题。另外,即使弹性容器120与座体110的内侧壁密封抵接,弹性容器120仍然可以向下扩张,也不会导致整个装置失效。本申请的液体缓存结构100没有活塞部件,运动阻力更小,运行更稳定,通过使用弹性容器120 可以将清洁液隔离在弹性容器120中,没有活塞密封圈处的泄露问题,可以使用气源作为动力源,结构简单,可以与其他部件公用气源驱动,无需另外设置其他动力源,也有利于降低成本。
在某些实施方式中,座体110包括内侧壁114,弹性容器120与内侧壁114间隔设置。
具体地,弹性容器120与内侧壁114之间间隔预设距离。如此,通过使弹性容器120与内侧壁114间隔设置,可以减小弹性容器120与内侧壁114的摩擦力,进而解决弹性容器120在运动时的卡涩问题。
请参阅图57,在某些实施方式中,液体缓存结构100还包括限位结构130,在弹性容器120扩张到预设程度时,限位结构130能够对弹性容器120进行限位。
具体地,限位结构130可以设置在弹性容器120的下方,在弹性容器120扩张到预设程度时,限位结构130用于限制弹性容器120,防止弹性容器120过度扩张。
如此,通过使用限位结构130对弹性容器120的扩张程度进行限制,可以防止弹性容器120在过度扩张后变形。
在某些实施方式中,液体缓存结构100还包括端盖140和安装件150,端盖140连接在座体110靠近第二开口113的一侧,安装件150连接弹性容器120,限位结构130包括连接安装件150的限位凸起131,在弹性容器120扩张到预设程度时,限位凸起131与端盖140抵接以对弹性容器120进行限位。具体地,安装件150用于连接弹性容器120和限位凸起131,使得弹性容器120的扩张受到一定的限制。如此,通过在靠近第二开口113的一侧设置端盖140、安装件150和限位凸起131,可以防止弹性容器120在过度扩张后变形。
请参阅图58和图59,在某些实施方式中,限位结构130包括限位台132,限位台132设于座体110内靠近第二开口113的一侧,且朝向弹性容器120凸出,在弹性容器120扩张到预设程度时,弹性容器120与限位台132抵接以对弹性容器120进行限位。
具体地,在抽出填充介质时,弹性容器120会得到扩张,而当弹性容器120扩张到预设程度时,限位台132会抵接弹性容器120,以防止其过度扩张。
如此,通过使用限位台对弹性容器120的扩张进行限制,可以防止弹性容器120因过度扩张而产生变形。
在某些实施方式中,液体缓存结构100还包括端盖140,连接在座体110靠近第二开口113的一侧,限位台132设置于端盖140。
具体地,在限位台132对弹性容器120进行限位时,端盖140用于为限位台132提供支撑力。如此,可以防止弹性容器120过度扩张而导致变形。
在某些实施方式中,液体缓存结构100还包括端盖140,端盖140连接在座体110靠近第二开口113的一侧,端盖140设有连通第二开口113的控制口141,填充介质通过控制口141抽出或注入。
具体地,将填充介质通过控制口141抽出以使得收容腔111形成负压, 弹性容器120进行扩张,进而弹性容器120可以吸入液体;将填充介质通过控制口141注入以使得收容腔111形成正压,弹性容器120进行压缩,进而弹性容器120可以排出液体。
如此,通过控制口141抽出或注入填充介质,可以控制弹性容器120的扩张或收缩,进而可以控制液体的吸入和排出。
在某些实施方式中,弹性容器120包括抵接面121,在液体缓存结构100处于常态时,抵接面121抵接缓存进液口211和缓存出液口221以密封缓存进液口211和缓存出液口221。
具体地,在液体缓存结构100处于常态时,若出液口240受到来自外部的负压或者进液口230受到来自外部的正压,可能会导致非正常情况下液体的排出和流入,而通过使用抵接面121密封缓存出液口221和缓存进液口211,可以阻挡外部的压力进入。
在某些实施方式中,弹性容器120的底部厚度大于预设厚度,便于密封缓存进液口211和缓存出液口221。
如此,通过对缓存进液口211和缓存出液口221的密封可以防止在出液口240负压时或进液口230正压时导致液体流入或排出。
在某些实施方式中,液体缓存结构100包括弹性件180,连接弹性容器120,在弹性件180处于常态时,弹性件180的第一端抵接弹性容器120,弹性件180的第二端抵接座体110,弹性件180为弹性容器120提供弹性力以使得抵接面121密封缓存进液口211和缓存出液口221。
具体地,弹性件180包括弹簧等具有弹性力的器件,在完成排出液体或抽入液体的操作后,弹性件180会将弹性容器120拉回预设位置,并使抵接面121密封缓存进液口211和缓存出液口221。
如此,通过在弹性容器120和座体110之间设置弹性件180,可以在完成排出液体或抽入液体的操作后,将弹性容器120复位至预设位置并对缓存进液口211和缓存出液口221进行密封,可以防止在出液口240负压时或进液口230正压时导致液体流入或排出。
在其他实施方式中,弹性容器120在常态下为压缩状态,弹性容器120可利用自身的状态密封进液口230和出液口240,可以省略弹性件180。
在某些实施方式中,液体缓存结构100还包括连接弹性容器120的安装件150,弹性件180的第一端通过安装件150抵接弹性容器120。
具体地,安装件150用于将弹性件180与弹性容器120相连接。如此,通过安装弹性件180可以防止在出液口240负压时或进液口230正压时导致液体流入或排出。
在某些实施方式中,弹性容器120包括弹性本体122和安装件150,安装件150设置于弹性本体122,其中,缓存进液口211和缓存出液口221通过管段伸入收容腔111内,安装件150朝向缓存进液口211和缓存出液口221的表面形成抵接面。
具体地,缓存进液口211和缓存出液口221下凸,伸入弹性容器120里 面,可以起支撑的作用、防止过度收缩变形,旁边的空间用于存储弹性容器120收缩时的褶皱,使弹性容器120更易收缩,且方便密封进液口230和出液口240,对弹性容器120收缩进行限位,控制排液量,并完成对缓存进液口211和缓存出液口221的密封操作。
如此,通过将缓存进液口211和缓存出液口221通过管段伸入收容腔内,可以防止弹性容器120过度收缩,以及在不需要抽入或排出液体的情况下,防止液体的抽入和排出。
请参阅图60,在某些实施方式中,安装件150呈凸起状,安装件150自弹性本体122的底部朝缓存进液口211和缓存出液口221凸出延伸,安装件150用于抵接缓存进液口211和缓存出液口221以密封缓存进液口211和缓存出液口221;安装件150朝向缓存进液口211和缓存出液口221的表面形成抵接面。
具体地,在弹性容器120处于常态时,呈凸起状的安装件150与缓存进液口211和缓存出液口221相抵接,从而实现对缓存进液口211和缓存出液口221的密封。
如此,通过在弹性本体122上设置安装件150,可以防止弹性容器120过度收缩,以及在不需要抽入或排出液体的情况下,防止液体的抽入和排出。

如此,通过设置第一单向阀250和第二单向阀260,可以在需要抽入液体时关闭排出液体的通道,在需要排出液体时关闭抽入液体的通道,防止非正常情况的出现。
请参阅图61,本申请实施方式提供了一种清洁设备,清洁设备包括清洁部件和上述任意一项实施方式的液体缓存箱1000,清洁部件能够利用液体缓存箱1000中的液体进行清洁,其中,清洁设备包括以下至少一种:清洁机器人、清洁基站、手持式洗地机。具体地,清洁部件可以是水箱、拖把等部件,液体缓存箱1000完成清洁设备在清洁过程中的抽入液体和排出液体的操作。如此,通过在清洁设备中加入液体缓存箱1000,可以使清洁变得更加高效。
本申请实施方式的液体缓存结构100、液体缓存箱1000和清洁设备中,弹性容器120收缩与扩张时所有的表面积都在受力,面积比活塞更大,能克服的阻力更大,通过使用弹性容器120能够使液体缓存结构100正常工作。
请参阅图62,本申请实施方式提供了一种液体缓存结构100,液体缓存结构100包括活塞筒110和活塞120,活塞筒110包括第一活塞筒111和第二活塞筒112,第一活塞筒111用于连通缓存进液口210和缓存出液口220,第二活塞筒112用于注入或抽出填充介质。活塞120包括相互连接的第一级活塞121和第二级活塞122,第一活塞筒111用于收容第一级活塞121,第二活塞筒112用于收容第二级活塞122,第一级活塞121的横截面积小于第二级活塞122的横截面积。从第二活塞筒112抽出填充介质时,第二级活塞122运动以带动第一级活塞121远离缓存进液口210和缓存出液口220,使得第一活塞筒111从缓存进液口210吸入液体。向第二活塞筒112注入填充介质时,第二级活塞122运动以带动第一级活塞121靠近缓存进液口210和缓存出液口220,使得第一活塞筒111从缓存出液口220排出液体。
具体地,液体可以是清洁液、清水、污水中的任意一种,在本申请实施例中,以液体为清洁液为例进行说明。
活塞筒110为液体缓存结构100的主体,活塞筒110分为两段,即第一 活塞筒111和第二活塞筒112。第一活塞筒111用于连通缓存进液口210和缓存出液口220,可以配合第一级活塞121抽取、存储液体。第二活塞筒112可以配合第二级活塞122,以用于注入或抽出填充介质,为第一级活塞121提供动力。
从第二活塞筒112抽出填充介质时,第二级活塞122因抽出填充介质产生的作用力而朝远离第一活塞筒111的方向进行运动,第二级活塞122与第一级活塞121相互连接,因此,第二级活塞122带动第一级活塞121远离缓存进液口210和缓存出液口220,使得第一活塞筒111中产生负压,液体通过缓存进液口210进入第一活塞筒111中;向第二活塞筒112注入填充介质时,第二级活塞122因注入填充介质产生的作用力而朝靠近第一活塞筒111的方向进行运动,第二级活塞122带动第一级活塞121靠近缓存进液口210和缓存出液口220,使得第一活塞筒111中的液体经缓存出液口220排出。填充介质可以为气体或者液体,在一个实施例中,填充介质例如为空气,可以通过气泵抽出或注入空气。
因为活塞的原理决定了活塞必须与座体的内侧壁密封抵接。而为了保证活塞在座体内能够运动顺畅,又需要减小活塞与座体的内侧壁之间的摩擦阻力。在相关技术中通常会在活塞与座体的内侧壁之间涂抹润滑油或润滑脂,而清洁液具有溶解油脂、污渍的特性,因此由于清洁液的存在,清洁液极易溶解润滑油或润滑脂,导致活塞与座体之间的润滑失效,使得活塞与座体的内侧壁容易卡涩,导致运动不畅。
本申请的液体缓存结构100中,活塞120分为两级,即相互连接的第一级活塞121和第二级活塞122,其中,第一级活塞121和第二级活塞122可以通过连接件123相互连接,第一级活塞121、第二级活塞122和连接件123可以一体成型。第一级活塞121的横截面积小于第二级活塞122的横截面积。第一活塞筒111配合第一级活塞121实现抽取、存储液体的功能,第一级活塞121的直径小,与活塞筒内侧壁之间的阻力小;第二活塞筒112配合第二级活塞122提供运动动力,第二级活塞122的由于直径大,横截面积大,受力大,在向第二活塞筒112内注入填充介质的过程中,填充介质与第二级活塞122的接触面积大,第二级活塞122较易被推动,如此,可以利用大动力对抗小阻力,实现整个活塞顺畅运动,进而实现液体泵送顺畅。本申请的液体缓存结构100可以使用气源作为动力源,结构简单,可以与其他部件共用气源驱动。例如,与清洁机器人配合的清洁基站中可以设置有水路系统,利用水路系统提供给清洁机器人自清洁的用水,以及回收清洁机器人进行自清洁后的污水,水路系统由于需要泵送清洗用水,以及泵吸污水至回收箱或泵向下水道。因此,水路系统中通常需要设置动力元件,动力元件可以包括气泵和/或水泵,由于气泵的工作原理,无需水经过泵体,可以实现水不过泵,由此降低了水中杂质卡涩泵体的风险,有利于提高动力元件的使用寿命,因此,水路系统可以优选采用气泵作为动力元件,或者至少部分水路采用气泵作为动力元件,液体缓存结构100可以采用气泵作为动力源,无需另外设置 其他动力源,也有利于降低成本。
当然,可以理解的是,液体缓存结构100可以不限于设于基站的水路系统,还可以是设于清洁机器人的水路系统,对应的,清洁机器人的水路系统的动力元件也可以包括气泵。
在某些实施方式中,第一级活塞121和第二级活塞122均为空心结构。
如此,可以节省第一级活塞121和第二级活塞122的材料,从而节约成本。另外,在同材料下,空心结构的设计可以使得第一级活塞121和第二级活塞122的重量更轻,便于在填充介质的作用下推动。
具体地,第一级活塞121和第二级活塞122可以通过注塑形成,在注塑形成第一级活塞121和第二级活塞122时,应该使得第一级活塞121的各处壁厚尽量均匀,使得第二级活塞122的各处壁厚尽量均匀,避免成型填充和冷却收缩不均匀而导致第一级活塞121或第二级活塞122存在缩影、气泡、变形等风险。另外,第一级活塞121的壁厚处于第一壁厚范围,第二级活塞122的壁厚处于第二壁厚范围,第一壁厚范围和第二壁厚范围可以相同或不同,第一壁厚范围和第二壁厚范围的取值在此不做具体限定。在满足结构和使用要求的条件下,尽可能采用较小的壁厚,如此可以使得塑胶模具冷却快、第一级活塞121和第二级活塞122的质量小,节省材料,降低成本。
在某些实施方式中,液体缓存结构100还包括第一密封件130,第一密封件130设于第一级活塞121的外周壁,第一密封件130与第一活塞筒111的内壁接触。
如此,能够通过第一密封件130密封第一活塞筒111内的液体。
具体地,第一密封件130可以为密封圈。第一级活塞121的外周壁可以开设有第一收容槽,第一密封件130可以至少部分收容在第一收容槽中并与第一活塞筒111的内壁接触,如此,第一密封件130密封第一活塞筒111内的液体,避免液体从第一活塞筒111流向第二活塞筒112。由于第一级活塞121的直径小,因此,第一密封件130的周长小,阻力小,便于推动第一级活塞121。
在某些实施方式中,液体缓存结构100还包括第二密封件140,第二密封件140设于第二级活塞122的外周壁,第二密封件140与第二活塞筒112的内壁接触。
如此,能够通过第二密封件140密封第二活塞筒112内的填充介质。
具体地,第二密封件140可以为密封圈。第二级活塞122的外周壁可以开设有第二收容槽,第二密封件140可以至少部分收容在第二收容槽中并与第二活塞筒112的内壁接触,如此,第二密封件140密封第二活塞筒112内的填充介质,从而使得填充介质的注入或抽出能够为第二级活塞122的运动提供动力。由于第二级活塞122的直径大,面积大,受力大,因此,填充介质的注入或抽出能够使得第二级活塞122具有大动力,便于推动第一级活塞121。
在某些实施方式中,第二级活塞122和第二密封件140可以增加润滑油, 第二活塞筒112用于供填充介质进入,清洁液基本不会进入第二活塞筒112内,因此,在第二活塞筒112与第二级活塞122之间涂设润滑油,也不会有清洁液进入第二活塞筒112内而将润滑油溶解失效,由于润滑油不易在第二活塞筒112与第二级活塞122之间失效,如此,可以进一步减小第二级活塞122和第二密封件140与第二活塞筒112的摩擦阻力,使得填充介质的注入或抽出能够为第二级活塞122提供更大的动力,便于推动第一级活塞121。
在某些实施方式中,液体缓存结构100还包括端盖150,端盖150连接在第二活塞筒112远离第一活塞筒111的一侧;端盖150设有控制口151,填充介质通过控制口151抽出或注入。
具体地,将填充介质通过控制口151抽出以使得第二活塞筒112形成负压,第二级活塞122朝靠近端盖150的方向进行运动,第二级活塞122带动第一级活塞121远离缓存进液口210和缓存出液口220,使得第一活塞筒111中产生负压,液体通过缓存进液口210进入第一活塞筒111中;将填充介质通过控制口151注入以使得第二活塞筒112形成正压,第二级活塞122朝远离端盖150的方向进行运动,第二级活塞122带动第一级活塞121靠近缓存进液口210和缓存出液口220,使得第一活塞筒111中的液体经缓存出液口220排出。
如此,通过控制口151抽出或注入填充介质,可以控制第二级活塞122运动,进而可以带动第一级活塞121,以控制液体的吸入和排出。
在某些实施方式中,端盖150与第二活塞筒112可拆卸连接,例如,端盖150与第二活塞筒112可以通过螺纹连接、卡合连接等方式实现可拆卸连接,如此,便于将活塞120从第二活塞筒112远离第一活塞筒111的一侧装入活塞筒110中,或者将活塞120从活塞筒110中拆卸出来。
在某些实施方式中,端盖150用于对第二级活塞122进行限位,第一级活塞121与第二级活塞122的总长度大于第二活塞筒112的内筒深度,以使第二级活塞122抵接端盖150时,第一级活塞121的远离第二级活塞122的部分处于第一活塞筒111内。
如此,通过端盖150对第二级活塞122进行限位,以避免第二级活塞122脱离第二活塞筒112,避免第一级活塞121脱离第一活塞筒111。
具体地,从第二活塞筒112抽出填充介质时,第二级活塞122朝远离第一活塞筒111的方向进行运动。当第二级活塞122被端盖150限位时,第二级活塞122处于最远离第一活塞筒111的位置,由于第一级活塞121与第二级活塞122相互连接,第一级活塞121与第二级活塞122的总长度(即活塞120的总长度,是第一级活塞121的长度、连接件123的长度、第二级活塞122的长度之和)大于第二活塞筒112的内筒深度,因此,在第二级活塞122抵接端盖150时,第一级活塞121的远离第二级活塞122的部分处于第一活塞筒111内,如此,端盖150可以避免第二级活塞122脱离第二活塞筒112;第一级活塞121与第二级活塞122的总长度大于第二活塞筒112的内筒深度,可以避免第一级活塞121脱离第一活塞筒111。
请参阅图63和图64,在某些实施方式中,液体缓存结构100还包括限位部160,限位部160设有缓存进液口210和缓存出液口220,限位部160用于对第一级活塞121进行限位,在第一级活塞121抵接限位部160时,第一级活塞121用于密封缓存进液口210和缓存出液口220。
具体地,限位部160设有缓存进液口210和缓存出液口220,从第二活塞筒112注入填充介质时,第二级活塞122朝靠近第一活塞筒111的方向进行运动并带动第一级活塞121靠近限位部160。当第一级活塞121被限位部160限位时,第一级活塞121处于最远离第二活塞筒112的位置,第一级活塞121远离第二级活塞122的一端密封缓存进液口210和缓存出液口220。
在液体缓存结构100处于常态时,若出液口320受到来自外部的负压或者进液口310受到来自外部的正压,可能会导致非正常情况下液体的排出和流入,而通过使用第一级活塞121密封缓存进液口210和缓存出液口220,可以阻挡外部的压力进入,从而避免非正常情况下液体的排出和流入。
如此,通过对缓存进液口210和缓存出液口220的密封可以防止在出液口320负压时或进液口310正压时导致液体流入或排出。
在某些实施方式中,第一级活塞121与第二级活塞122的总长度大于第一活塞筒111的内筒深度,以使第一级活塞121抵接限位部160时,第二级活塞122的远离第一级活塞121的部分处于第二活塞筒112内。
如此,通过限位部160对第一级活塞121进行限位,以避免第一级活塞121脱离第一活塞筒111,避免第二级活塞122脱离第二活塞筒112。
具体地,从第二活塞筒112注入填充介质时,第二级活塞122朝靠近第一活塞筒111的方向进行运动并带动第一级活塞121靠近限位部160。当第一级活塞121抵接限位部160时,第一级活塞121处于最远离第二活塞筒112的位置,由于第一级活塞121与第二级活塞122相互连接,第一级活塞121与第二级活塞122的总长度大于第一活塞筒111的内筒深度,因此,在第一级活塞121抵接限位部160时,第二级活塞122的远离第一级活塞121的部分处于第二活塞筒112内,如此,限位部160可以避免第一级活塞121脱离第一活塞筒111;第一级活塞121与第二级活塞122的总长度大于第一活塞筒111的内筒深度,可以避免第二级活塞122脱离第二活塞筒112。
通过端盖150和限位部160的限位,可以确定第一级活塞121每次的移动量,从而确定每次吸入、排除液体的量。
在某些实施方式中,第二活塞筒112靠近第一活塞筒111的一侧设有气孔1121,气孔1121连通第二活塞筒112与外界。
如此,可以通过气孔1121平衡第一级活塞121和第二级活塞122之间的压力变化。
具体地,第二活塞筒112靠近第一活塞筒111的一侧设有气孔1121,气孔1121连通第二活塞筒112与外界,由于第一级活塞121的横截面积和第二级活塞122的横截面积不同,因此,在第一级活塞121和第二级活塞122运动时,第一级活塞121和第二级活塞122之间的空间发生变化,从而导致存 在压力变化,气孔1121可以用于平衡该压力变化。例如,从第二活塞筒112抽出填充介质时,第二级活塞122朝远离第一活塞筒111的方向进行运动并带动第一级活塞121远离缓存进液口210和缓存出液口220,使得第一级活塞121和第二级活塞122之间的空间变大,外界的空气可以通过气孔1121进入第二活塞筒112中;从第二活塞筒112注入填充介质时,第二级活塞122朝靠近第一活塞筒111的方向进行运动并带动第一级活塞121靠近缓存进液口210和缓存出液口220,使得第一级活塞121和第二级活塞122之间的空间变小,第二活塞筒112中的空气可以通过气孔1121进入外界,从而平衡因为第一级活塞121和第二级活塞122之间的空间变化而造成的压力变化。
本申请实施方式提供了一种液体缓存箱1000,液体缓存箱1000包括上述任意一种实施方式的液体缓存结构100和传输管300,传输管300连通缓存进液口210和缓存出液口220。
具体地,液体缓存结构100通过控制口151控制第二级活塞122在第二活塞筒112内运动,控制第一级活塞121在第一活塞筒111内运动,以向传输管300传输负压或者正压。如此,通过将液体缓存结构100和传输管300相结合,可以实现对液体的抽入和排出。
在某些实施方式中,液体缓存结构100和传输管300可以一体成型。在其他实施方式中,液体缓存结构100和传输管300也可以相互独立形成并通过螺纹连接、卡合连接等连接方式结合在一起。
在某些实施方式中,传输管300包括进液口310和出液口320,进液口310通过第一单向阀330连接缓存进液口210,缓存出液口220通过第二单向阀340连接出液口320。其中,第一单向阀330从进液口310到缓存进液口210的方向上单向导通,第二单向阀340从缓存出液口220到出液口320的方向上单向导通。
具体地,第一单向阀330和第二单向阀340可以为鸭嘴阀或者伞阀。在需要抽入液体时,第二级活塞122带动第一级活塞121远离缓存进液口210和缓存出液口220,使得第一活塞筒111中产生负压,此时第一单向阀330打开,第二单向阀340关闭,液体通过进液口310、缓存进液口210进入第一活塞筒111中。在需要排出液体时,第二级活塞122带动第一级活塞121靠近缓存进液口210和缓存出液口220,使得第一活塞筒111中产生正压,此时第一单向阀330关闭,第二单向阀340打开,第一活塞筒111中的液体经缓存出液口220、出液口320排出。
如此,通过设置第一单向阀330和第二单向阀340,可以在需要抽入液体时关闭排出液体的通道,在需要排出液体时关闭抽入液体的通道,防止非正常情况的出现。
请参阅图63,在一个实施例中,第一级活塞121密封缓存进液口210和缓存出液口220,使得常态下缓存进液口210和缓存出液口220关闭,防止在出液口320连接清水箱且清水箱需要抽负压进清水时,将清洁液从进液口310的清洁液瓶中直接抽出。
请参阅图65,本申请实施方式提供了一种清洁设备,清洁设备包括清洁部件和上述任意一项实施方式的液体缓存箱1000,清洁部件能够利用液体缓存箱1000中的液体进行清洁,其中,清洁设备包括以下至少一种:清洁机器人、清洁基站、手持式洗地机。具体地,清洁部件可以是水箱、拖布等部件,液体缓存箱1000完成清洁设备在清洁过程中的抽入液体和排出液体的操作。如此,通过在清洁设备中加入液体缓存箱1000,可以使清洁变得更加高效。
本申请实施方式的液体缓存结构100、液体缓存箱1000和清洁设备中,第一级活塞121配合第一活塞筒111用于吸入液体或排出液体,第一级活塞121的横截面积小,阻力较小;第二级活塞122配合第二活塞筒112用于提供运动动力,第二级活塞122的横截面积大,受力较大,如此,能够利用大动力对抗小阻力,实现活塞顺畅运动。
以上所述的仅为本申请的部分或优选实施例,无论是文字还是附图都不能因此限制本申请保护的范围,凡是在与本申请一个整体的构思下,利用本申请说明书及附图内容所作的等效结构变换,或直接/间接运用在其他相关的技术领域均包括在本申请保护的范围内。
