具体实施方式
需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的技术特征可以相互组合,具体实施方式中的详细描述应理解为本申请宗旨的解释说明,不应视为对本申请的不当限制。
本申请实施例提供一种清洁设备,该清洁设备可以用于清洁地面、玻璃等清洁介质,清洁设备工作时,清洁设备放置于清洁介质表面即可。
清洁设备可以是扫地机器人、擦窗机器人,还可以是类型的设备,在此不做限制。本申请实施例中,以清洁设备为扫地机器人为例进行描述。
请参阅图1,清洁设备包括泵水装置30、清洁区10a以及工作执行机构20;其中,泵水装置30包括容纳部31以及过渡连接机构33,容纳部31形成有容纳空间310、以及与容纳空间310连通的出水口30b,出水口30b与清洁区10a连通,例如,通过出水管37连通;过渡连接机构33与工作执行机构20驱动连接,过渡连接机构33在工作执行机构20的驱动下能够 将容纳空间310内的水泵入清洁区10a。
本申请实施例的清洁设备,利用现成的工作执行机构20作为动力源,通过过渡连接机构33驱动泵水操作,清洁区10a所需的补水量由工作执行机构20的动作和容纳空间310内用于储水水的容积来决定,无需通过控制电路进行控制,相比于现有技术中的水泵补水的方式,本申请实施例的泵水装置30结构可靠性和实用性更高、生产制造成本更低,有利于推广使用。
需要说明的是,所述的工作执行机构20指的是为实现清洁设备清洁功能的对外执行机构,例如,行走轮20′或滚刷。行走轮20′执行清洁设备的行走功能,清洁设备需要通过行走轮20′的行走来实现不断地清洁工作;滚刷执行清洁设备刮刷清洁介质的功能。
清洁区10a指的是用于与清洁件40接触的部位,清洁件40可以是抹布、海绵等,例如,请参阅图1,清洁区10a可以为用于安装清洁件40的支架12的底部,清洁设备正常工作前,在支架12的底部安装清洁件40,容水空间310内的水泵入清洁区10a,清洁区10a的水被清洁件40吸收,随后在清洁设备行进过程中,清洁件40对清洁介质进行擦拭清洁。
需要说明的是,过渡连接机构33可以是借助其他结构将容纳空间310内的水泵入清洁区10a;也可以是在不借助其他结构的情况下将容纳空间310内的水泵入清洁区10a,例如,过渡连接机构33在工作执行机构20的驱动下持续单向地向所述容纳空间310内泵入空气或其他气体,容纳空间310内的水在气压作用下泵入清洁区10a。
本申请实施例中,过渡连接机构33借助其他结构将容纳空间310内的水泵入清洁区10a,具体地,泵水装置30包括泵水部32,泵水部32活动地设置于容纳空间310内,泵水部32和容纳部31共同围设成容水腔311,泵水部32能够将容水腔311内的水泵入清洁区10a,也就是说,过渡连接机构33借助泵水部32将容纳空间310内的水泵入清洁区10a。本申请实施 例通过过渡连接机构33将动力传递至泵水部32,进而驱动泵水部32进行排水操作,如此便于直接对容水腔311内的水施加更大的压力,便于将容纳腔311内的水可靠性泵入清洁区10a。
容纳部31的具体结构不限,只要能够容纳一定容量的水即可,在此不做限制。一些实施例中,清洁设备包括水箱11,水箱11中预先存储一定容量的水或清洁液,为便于描述,本申请实施例以水为例进行描述。容纳部31可以是水箱11的至少部分结构,例如,在水箱11内的空间中隔离出部分空间以形成容纳部31的容纳空间,水箱11内预先存储的水通过一定孔径的通孔进入容水腔311内;再例如,水箱11本身即为容纳部31,水箱11内的空间即为上述的容纳空间311。
再例如,请参阅图1,本申请实施例中,容纳部31位于水箱11的外侧,容纳部31形成有与容水腔311连通的进水口31a,进水口31a与水箱11连通。可以理解的是,容纳部31可以与水箱31紧固连接,也可以与水箱31间隔设置,在此不做限制。本申请实施例中,将容纳部31设置于水箱11的外侧,一方面能够使得水箱11在清洁设备有限的空间内具有较大的容积,提升蓄水能力,另一方面,可以灵活布置水箱11、清洁区10a和容纳部31之间的相对位置,三者之间只要通过相应的管路连通即可,如此能够使得清洁设备的结构设计更加灵活,清洁设备的结构布局更加合理、紧凑。
本申请实施例中,工作执行机构20为行走轮20′,过渡连接机构33与行走轮20′连接,行走轮20′的转动过程与清洁设备的行进距离有关,如此,泵水部32的运动幅度与清洁设备的行进距离相关联。具体地,清洁设备不行进时,行走轮20′静止不动,过渡连接机构33保持静止,泵水部32也不会运动,此时清洁件40不执行擦拭清洁工作,泵水装置30也不会向清洁区10a排水;清洁设备行进短距离情况下,行走轮20′的转动幅度较小,泵水部32的运动行程也较小,则泵水装置30泵入清洁区10a的排水量也比 较小,而在清洁设备行进短距离情况下,清洁件40所需的补水量也会较少,因此,泵水装置30向清洁件40的排水量与清洁件40所需的补水量能够较好的匹配;同理,清洁设备行进距离较大时,泵水装置30泵入清洁区10a排水量的较大,清洁件40所需的补水量也较大。
一实施例中,过渡连接机构33连接于行走轮20′的轴向一侧。如此,便于过渡连接机构33与行走轮20′的连接。进一步地,过渡连接机构33连接于行走轮20′的轴向内侧,如此,过渡连接机构33不会暴露于清洁设备的外侧,在清洁设备工作过程中,过渡连接机构33不会与外界的其他物件发生干涉;再者,也便于泵水装置30的结构布置更加合理、紧凑。
容纳部31和泵水部32的结构形式多样,例如,一实施例中,容纳部31呈筒状,相应的,泵水部32为活塞32′;另一实施例中,容纳部31呈蜗壳状,泵水部32为转子。
水箱11、工作执行机构20、过渡连接机构33以及清洁区10a的相对位置可以根据需要适当变化。
以下结合附图对本申请的具体实施例进行描述。
第一实施例
请参阅图1和图2,本实施例中,容纳部31位于水箱11的外侧。容纳部31呈筒状,容纳部31的一端为封闭端,另一端为开口端,泵水部32为活塞32′,活塞32′在容纳部31内直线往复运动,活塞32′交替地将水箱11内的水引入容水腔311以及将容水腔311内的水泵入清洁区10a。也就是说,同一时刻,将水箱11内的水引入容水腔311的操作以及将容水腔311内的水泵入清洁区10a的操作只能择一选择,具体地,当过渡连接机构33驱动活塞32′沿图1所示左方的第一方向滑动,容水腔311体积扩大,导致容水腔311内形成负压,水箱11内的水在负压作用下被吸入容水腔311内,在该过程中,出水口30b与清洁区10a之间的水路处于截止状态。当过渡连 接机构33驱动活塞32′沿图1所示右方的第二方向滑动,活塞32′对容水腔311内的水施加作用力,使得容水腔311内的水建立一定的水压,该水压能够将水泵入清洁区10a,在该过程中,进水口31a与水箱11之间的水路处于截止状态。
为了便于对进水口31a与水箱11之间的水路进行开闭控制,以及便于对出水口30b与清洁区10a之间的水路进行开闭控制,可以在相应的水路上设置阀体,以适时打开或关闭。阀体的结构类型不限,可以是电控阀、液控阀等。
本实施例中,泵水装置30包括第一单向阀34,第一单向阀34属于液控阀的一种,即不需要电磁控制即可打开和关闭控制。第一单向阀34设置于进水口31a和水箱11之间的水路上。可以理解的是,第一单向阀34能够允许水流单向地从水箱11一侧流入进水口31a一侧,也就是说,第一单向阀34的进液端与水箱11连通,第一单向阀34的出液端与进水口31a连通。第一单向阀34结构简单,无需电控,能够根据水压自动实现开启和关闭。例如,当容水腔311内的负压大于第一单向阀34的开启压力,第一单向阀34导通,水箱11内的水在容水腔311的负压作用下经第一单向阀34进入容水腔311内;当容水腔311内的水建立压力时,水压反向作用于第一单向阀34,第一单向阀34关闭,水箱11内的水压不足以开启第一单向阀34,因此,第一单向阀34能够稳定地、可靠地、自动地处于截止状态。
泵水装置30包括第二单向阀35,第二单向阀35设置于出水口30b和清洁区10a之间的水路上。第二单向阀35的作用原理和工作过程与第一单向阀34相似,在此不再赘述。
可以理解的是,可以选择阀体的组配,例如,一些实施例中,可以在出水口30b和清洁区10a之间的水路上设置上述的第二单向阀35,而在进水口31a和水箱11之间的水路上设置电控阀或其他类型的液控阀;另一实 施例中,可以在进水口31a和水箱11之间的水路上设置上述的第一单向阀34,而在出水口30b和清洁区10a之间的水路上设置电控阀或其他类型的电控阀。
以出水口30b为例,如果出水口30b位于容纳部31的侧壁上,即位于非封闭端的位置,当活塞32′朝向封闭端一侧运动,如果活塞32′运动至活塞32′的周缘堵住出水口30b,容水腔311内的水无法排出,当活塞32′在过渡连接机构33的驱动下继续朝向封闭端一侧运动时,容水腔311内的水压憋压,压力持续升高,如此可能会损坏活塞32′、容纳部31或者上述的阀体。因此,产品设计时,活塞32′的运动幅度不能覆盖出水口30b所在位置,但如此会导致在同等条件下容纳部31沿活塞32′运动方向的尺寸增加。
为此,本申请实施例,进水口31a和出水口30b设置于容纳部31沿活塞32′滑动方向一侧的端部,即位于容纳部31的封闭端,如此,活塞32′能够一直运动至与封闭端接触的位置,能够使得容纳部31在同等条件下结构更加紧凑,也能防止容水腔311憋压。
本申请实施例中,请参阅图2,过渡连接机构33为曲柄33′。具体地,曲柄33′的一端与活塞32′背离容水腔311的一侧连接,曲柄33′的另一端与工作执行机构20转动连接,工作执行机构20具有第一转动轴线(参照图1中的O1点),即工作执行机构20绕第一转动轴线自转,曲柄33′的第二端具有第二转动轴线(参照图1中的O2点),第一转动轴线和第二转动轴线偏心设置,即曲柄33′跟随工作执行机构20转动的过程中,既绕第一转动轴线公转,也绕第二转动轴线自转,工作执行机构20通过曲柄33′驱动活塞32′直线往复运动,也就是说,工作执行机构20、曲柄33′以及活塞32′形成曲柄33′滑块结构,曲柄33′能够将工作执行机构20的转动运动形式转换为活塞32′的直线滑动运动形式。
本实施例中,工作执行机构20为行走轮20′。可以理解的是,工作执 行机构20也可以是滚刷或者其他类型的工作执行机构20。
第二实施例
请参阅图3,与第一实施例不同的是,本实施例中,过渡连接机构33包括凸轮331、滑杆332以及弹性件333,滑杆332的一端与活塞32′转动连接,例如,铰接,弹性件333对滑杆332施加朝向凸轮331的作用力,以将滑杆332的另一端压靠于凸轮331的周向表面,工作执行机构20具有第一转动轴线,凸轮331与工作执行机构20同轴紧固连接,也就是说,工作执行机构20绕第一转动轴线自转时,凸轮331也绕第一转动轴线自转。
由于凸轮331的周向表面形状为非圆形,凸轮331在绕第一转动轴线自转过程中,滑杆332会在弹性件333和凸轮331的共同作用下发生直线往复移动,进而带动活塞32′直线往复运动。
具体地,申请实施例中,弹性件333为弹簧,弹簧套设于滑杆332上,滑杆332对弹簧的伸缩运动起导向作用,提升弹簧的可靠性。弹簧的一端抵靠于活塞32′背离容水腔311的一侧。进一步,请继续参阅图3,滑杆332的周向形成有凸缘结构3321,弹簧的另一端抵靠于该凸缘结构3321朝向容纳部31的一侧,即弹簧夹设于凸缘结构3321和活塞32′之间。
第三实施例(图未示)
与第一实施例不同的是,本实施例中,容纳部31为蜗壳状,泵水部32为转子,转子在容纳部31内转动,转子同步地将水箱11内的水引入容水腔311以及将容水腔311内的水泵入清洁区10a。也就是说,转子在进行将水箱11内的水引入容水腔311内的操作过程同时,也进行将容水腔311内的水泵入清洁区10a的操作过程,两个操作过程同步进行。
该实施例中,进水口31a和出水口30b分别位于转子的相对两侧,转子将容纳空间310分隔为第一腔和第二腔,第一腔和第二腔共同形成容水腔311,也就是说,进水口31a与第一腔连通,出水口30b和第二腔连通, 转子转动时,转子将第一腔内的水挤入第二腔内,第一腔产生负压,水箱11内的水在该负压作用下被吸入第一腔内,第二腔内的水建立一定的水压,该水压将第二腔内的水泵入清洁区10a。
工作执行机构20具有第一转动轴线,转子具有第三转动轴线,第一转动轴线和第三转动轴线平行且偏心设置,过渡连接机构33能够将工作执行机构20的转矩传递至转子。也就是说,过渡连接机构33为转矩传递结构,例如,过渡连接机构33为传送带或者齿轮结构。
本申请提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合。
以上所述仅为本申请的较佳实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
