Description

双桶真空吸尘器
技术领域
本发明大致涉及真空吸尘器,更具体地说,涉及湿/干桶式真空吸尘器。
发明背景
桶式真空吸尘器能够容纳干燥的物质,例如碎屑或污垢,也能够容纳液体。这样的真空吸尘器典型地包括设置在气动推进器外壳内的气动推进器,其与桶的内部流体连通。气动推进器在桶内创造出低压区域以用吸尘器打扫干燥的和液体的物质。电动机运转地结合于气动推进器。
湿/干真空吸尘器为不同的应用提供多种尺寸。一般而言,桶和电动机的尺寸依待用吸尘器打扫的碎屑和、或液体的数量变化。因此,大体积的桶和较大的电动机提供给打算供较大的任务使用的真空吸尘器,而小体积的桶和较小的电动机提供给打算供较小的任务使用的装置。较大的装置较重且较难于携带,因此典型地提供轮脚以便利于沿一般平坦的表面移动。同样的,较大的装置通常用于收集来自地板、地面或相似的区域的碎屑和、或液体。而较小的装置具有减少的体积容量,它们较轻且较容易携带,因而可以用于较大的装置不适合或难于使用的区域。比如说,较小的装置可以用来打扫楼梯的台阶、水槽或隔开地板或地面或另外的需要在使用时携带真空吸尘器的其它区域。
使用具有与待用吸尘器打扫的碎屑和、或液体的体积大致匹配的收集容量的真空吸尘器常常是理想的。虽然有上述的可携带问题,考虑相关的倒空收集的碎屑和、或液体,保养以及清洁真空吸尘器,使得真空吸尘器的容量与待用吸尘器打扫的物质的体积充分地匹配是理想的。同样的,使用者倾向于将较小的真空吸尘器用于较小体积的任务,将较大的真空吸尘器用于较大体积的任务。令人遗憾的是,使用者面临小的和较大的两种体积的任务,必须或者尝试将单一的真空吸尘器使用于两种应用,或者购买两个或更多的真空吸尘器各自适合特定的任务。

详细描述
所公开的真空吸尘器具有较小的、可分离的真空装置,其可释放地附接于较大的底部单元桶组件。其提供具有小的和大的容量结构,适合具有不同体积、场所或其它特征的用吸尘器打扫的应用的组合真空吸尘器。该真空吸尘器包括单一的真空源,其尺寸适合使用较大的桶构造,还与较小的真空装置结合以及形成可移动的整体。较小的真空装置可以迅速且容易地附接于较大的桶组件,以及从较大的桶组件移开,以便利于使用所希望的结构的真空吸尘器。
依照本发明的真空吸尘器10在图1-8中举例说明。真空吸尘器10包括底部单元11,其具有支撑在轮脚14上的第一桶12。桶12包括帮助使用者举起和移动真空吸尘器10的把手16,并具有入口18和由可移开的盖22覆盖的出口20。罩组件24通过锁件25可释放地附接于第一桶12的上部。罩组件至少封住桶的一部分,从而在桶内形成第一内部收集腔26。如图6中的最佳显示,入口18延伸到桶12内且包括导向件44,其指引空气、碎屑和液体进入到第一内部收集腔26内。
可分离单元30可释放地结合于底部单元11。可分离单元30包括第二桶32和通过锁件35可释放地附接于桶32的罩组件34。第二桶32包括到第二内部收集腔82的入口36。罩组件34包括把手40。
可分离单元30通过附接于外部桶组件11的可释放的扣件,例如锁件42,紧固于底部单元11。如图2中的最佳显示,图示的各锁件42可释放地接合制动器43,且可以绕轴线(例如螺纹固定于罩组件24的螺钉45(图10))枢轴转动。柄部47便于抓握和在螺钉45周围移动锁件42。图示的各锁件42进一步包括由柄部47向上及向内凸出的肩部49,以及由柄部47向内及向上延伸的翼片53(图10)。制动器(detent)43紧固于罩组件24,且包括唇缘55,其向外及向下延伸形成凹槽57。
图示的锁件42可以移动到锁定位置,在此位置翼片53通过唇缘55保持在凹槽57内。翼片53和唇缘55是有弹性可弯曲的,以允许当向外的方向的力施加于柄部47时,翼片53滑过唇缘55到解锁位置,而当向内的力施加于柄部47时,回到锁定位置。在锁定位置,肩部49凸出于脊部59之上且紧密地配合靠着脊部59,其形成于罩组件34内以维持真空装置30与外部桶组件11的接合。锁件42可以移动到解锁位置以允许真空装置30从外部桶组件11移开。其它的锁件排列可同样使用。
图示的第一桶12和第二桶32具有不同的容量。比如说,第一桶12可以保存十加仑的物质,而第二桶32可以具有两加仑的容量。这里提出的桶的体积仅仅是示范,因为多种不同的尺寸可以用于桶12、32中的任一个。此外,用在这个例子中的相对尺寸并不意味提出需要的或优选的第一和第二桶12、32之间的尺寸比率。
可分离单元30可接合于外部桶组件11,以使第二桶32与第一桶12流体连通。如图6中的最佳显示,容座28结合外部桶组件11的罩组件24。容座28包括插口表面29,其接合于可分离单元30的第二桶32。在图示的实施例中,插口表面29一般为凹形,形成杯状的插口空间31。第二桶32具有至少局部地插入插口空间31内的尺寸。插口表面31可紧密地配合第二桶32的外部表面的大半部,如图所示。
在图示的排列中,容座内的中间腔58于第一内部收集腔26和第二内部收集腔82之间流体连通。在图示的实施例中,中间腔58位于内壁50和外壁52之间。外壁52内的第一孔51在中间腔58和第一收集腔26之间建立流体连通。第二孔54形成于内壁50内且支承密封件61,如图9中的最佳显示,其由弹性物质例如橡胶形成。密封件61包括具有接合第二孔54的尺寸的底部63,以及延伸到插口空间31内的密封部65。密封部65具有接合和密封入口36的外部的尺寸,从而在中间腔58和第二收集腔82之间建立流体连通。
在图6中所示的示范的结构中,内壁50是作为罩组件24的一部分形成的,而外壁52与内壁50及从罩组件24下垂的凸肋56结合。此外,内壁50形成上述插口表面29。在某些排列中,可能可以排除内壁50,所以中间腔58由外壁52和第二桶32的外部形成。在这种情况下,外壁52的一部分形成插口表面以接合及密封第二桶32。一般优选双壁结构,因为在两个桶之间需要密封的较小区域(因而一般形成较好的密封的可能性更大),以及因为当可分离单元插入插口空间31内时,其减少进入中间腔58的第二桶32外部的灰尘或污垢。
中间腔58的形状可以改变以调节容座28的第一和第二孔51、54之间的空气流动。如图8的最佳显示,图示的外壁52包括两个凸壁部60,其限定外部凹口62。凸壁部60在中间腔58内生成增加贯穿中间腔的空气流动容量的扩充部64。定制外部凹口62的尺寸以调节由入口18延伸到第一内部收集腔26内的导向件44的至少一部分。
过滤器盒66结合于容座外壁52,如图6中的最佳显示。过滤器盒66由容座外壁52向下延伸至第一内部收集腔26内。当第一内部收集腔26达到其液体容量时,过滤器盒66内的浮标68可中断真空吸尘器的运转,与本领域已知的一样。过滤器70可移动地附接于过滤器盒66。
真空源结合于真空装置30的罩组件34,用于产生贯穿真空吸尘器10的真空空气流动。如图6中的最佳显示,真空源包括电动机72,其使轴74连同气动推进器76旋转。气动推进器76设置在具有孔80的气动推进器外壳78内,该孔80与由桶32限定的第二或里面的内部收集腔82流体连通。
过滤器盒84设置在孔80和第二内部收集腔82之间。当内部桶32中的液体达到最大量标准时,过滤器盒84内的浮标86可切断真空空气流动。过滤器88可移动地结合于过滤器盒84。真空装置入口36同样包括指引空气和物质流动到第二内部收集腔82内的导向件37。
容座28可以成形为便利于真空装置30插入容座28内,使得入口36与内部腔58适当地对准。如图2中的最佳显示,真空装置入口36由内部桶32向外延伸形成具有横向的轮廓92的入口凸出部90。容座外壁52限定通道94,其尺寸被定制以紧密配合入口凸出部(rejection)横向的轮廓92,从而自动地使内部桶32在容座28内定位。通道94与扩充部64流体连通以便利于贯穿中间腔58的充分容量的空气流动。
所述真空吸尘器10可以选择性地放置于大容量和小容量两种结构中。在大容量结构中,真空装置30结合容座28以在第一内部腔26内产生贯穿入口18的空气流动。为此,气动推进器76由电动机72运转以在第二内部收集腔82内产生局部真空。局部真空连接第一内部收集腔26,贯穿中间腔58。因此,在入口18产生吸力,其可以通过软管(未示出)被指引到所希望的区域。为了大体积的用吸尘器打扫的应用,真空吸尘器10可以大容量结构运转。
在大容量结构的运转也可以产生更干净的排气,由真空吸尘器10排出。在大容量结构中,通过真空源的运转产生的空气流动路径在排出到大气之前通过过滤器70和过滤器88两者。这样双重的过滤减少了由真空吸尘器10和排气一起排出的微粒或其它物质的数量。应当知道,当真空吸尘器10在大容量结构运转时,物质预定仅收集在外部桶12中。当图示的真空吸尘器构造成大容量应用时,除小比率的微粒能穿过过滤器70但是被过滤器88阻挡之外,用真空吸尘器打扫的物质一般仅收集在外部桶12中。
真空吸尘器10也可以通过由容座28上移开真空装置30在小容量结构运转。为此,锁件42可以打开,所以真空装置30可以容易地从容座28移开,暴露入口36。然后软管(未示出)可附接于入口36的外部。真空吸尘器10在小容量结构中运转与大多数先前的湿/干真空吸尘器大致是相似的,在于由气动推进器76产生的局部真空与入口36连接,将物质吸引入第二内部收集腔82内。第二内部收集腔内的局部真空可以通过软管指引到所希望的位置。因为内部桶32较小,真空装置30适用于待收集物质体积较小或需要更轻便的真空吸尘器的应用。
虽然本发明描述了特殊的例子,其实质上仅为例证性的而不意味着限制。对于熟悉本领域的普通技术人员来说,对示范的实施例进行可能地改变、增加和删除显然并无远离本发明的精神和范围。
