本申请涉及净水设备技术领域,特别是涉及可拆卸滤芯组件和净水机。
随着净水设备技术领域的发展,净水机的使用越来越普及。净水机中的滤芯在使用一段时间后其过滤能力将下降。为了保持良好的过滤效果,需要更换滤芯。滤芯一般封装在滤瓶体中构成滤芯组件。滤瓶体与净水机整机壳体连接,使得滤芯组件装配在净水机整机中。更换滤芯的方式可整体更换滤芯组件或只更换滤芯保留滤瓶体。只更换滤芯保留滤瓶体的更换方式能够有效减少更换成本,滤瓶体在不损坏的情况下可以一直沿用。
对于只更换滤芯保留滤瓶体的更换方式,为了从滤瓶体中取出滤芯,一般在滤瓶体上设有可拆卸的滤瓶盖。滤瓶盖从滤瓶体上卸下后即可将滤芯从第一瓶口抽出,替换新的滤芯使用。滤瓶盖与滤瓶体之间一般采用螺纹连接,滤瓶体与整机壳体之间采用旋扣的方式连接。由于作用力都是沿周向,在拆卸更换滤芯的过程中,易出现滤瓶体未与整机壳体拆开时,将滤瓶盖拧松的情况,导致拆卸更换滤芯的过程中漏水。为了避免漏水的情况发生,可以在相对于整机旋拧滤瓶体的过程中限制滤瓶盖相对于滤瓶体转动。但是要完成拆卸更换滤芯的过程,滤瓶盖必然要与滤瓶体拆开,两者之间需要能够相对转动。既避免拆卸时漏水,同时又使得更换滤芯的过程更加便利,成为提升净水机使用性能的重要方面。
发明内容

为使本公开的上述目的、特征和优点能够更加明显易懂,下面结合附图对本公开的具体实施方式做详细的说明。在下面的描述中阐述了很多具体细节以便于充分理解本公开。但是本公开能够以很多不同于在此描述的其它方式来实施,本领域技术人员可以在不违背本公开内涵的情况下做类似改进,因此本公开不受下面公开的具体实施例的限制。
如图1、图2和图3所示,在一个实施例中,提供了一种可拆卸滤芯组件10,包括滤瓶体11。所述滤瓶体11的第一瓶口111处可以旋拧滤瓶盖12,进而将所述第一瓶口111封堵。所述滤瓶体11的第二瓶口112处能够旋扣在净水机的滤芯安装座20上,使得所述滤瓶体11中的滤芯19与所述滤芯安装座20上的各个水口对应导通。
所述可拆卸滤芯组件10还包括滤瓶盖12。所述滤瓶盖12旋拧在所述滤瓶体11的第一瓶口111处,形成用于放置滤芯19的滤瓶。
当使用一段时间需要更换滤瓶中滤芯19时,可以先将所述滤瓶体11从所述滤芯安装座20上拆下,使得净水机中的水流通路与所述滤瓶体11分开。然后再将滤瓶盖12从所述滤瓶体11上卸下,将所述第一瓶口111打开,将滤芯19从所述滤瓶中取出进行更换。
当所述滤瓶盖12旋拧到所述滤瓶体11上时旋转的方向,同所述滤瓶体11旋扣到所述滤芯安装座20时的旋转方向一致时,在更换滤芯19的过程中,作用在滤瓶上的旋转力可能在未将滤瓶体11从滤芯安装座20上卸下之前,先将滤瓶盖12从滤瓶体11上拧松,导致漏水的情况发生。
基于此,在一个实施例中,如图3所示,提供了一种限位件131,利用所述限位件131作为滤瓶体11与滤瓶盖12之间的中间元件,在拆卸的过程中避免未将滤瓶体11从滤芯安装座20上卸下之前,却先将滤瓶盖12从滤瓶体11上拧松的情况发生。
具体地,如图4所示,所述限位件131相对于所述滤瓶能够在远离或靠近所述第一瓶口111的方向上来回移动。当所述限位件131移动前进到锁紧位置时,如图4和图6所示,所述滤瓶体11和滤瓶盖12均与所述限位件131限位配合,限制所述滤瓶盖12从所述第一瓶口111处松脱打开所述第一瓶口111。当所述限位件131移动退出所述锁紧位置时,所述滤瓶体11和所述滤瓶盖12至少一者能够相对于所述限位件131运动,使得所述滤瓶盖 12能够从所述滤瓶体11上旋下。
当所述滤瓶体11装配到滤芯安装座20上时,所述限位件131位于所述锁紧位置,所述滤瓶盖12被限制,无法从所述第一瓶口111处松脱开启所述第一瓶口111,此时作用在所述滤瓶上的旋转力只能够传递到所述滤瓶体11与所述滤芯安装座20配合处,使得滤瓶体11与滤芯安装座20之间旋转拆开。
一般所述可拆卸滤芯组件10装配在净水机上后,滤瓶盖12所在这一端暴露在外。拆卸过程中出于方便考虑,一般直接将力作用在滤瓶盖12上进而为滤瓶提供旋转力。因此更有必要设置所述限位件131,避免漏水情况发生。
当滤瓶体11从滤芯安装座20上拆下后,所述限位件131移动退出所述锁紧位置,所述滤瓶盖12能够相对于所述滤瓶体11转动,从所述第一瓶口111处卸下。
换言之,只有当所述滤瓶体11先从滤芯安装座20上拆下后,才能够相对于滤瓶体11拧动滤瓶盖12,从而有效避免漏水的情况发生。而且基于所述限位件131是通过在所述滤瓶上移动而切换状态,且移动方向为远离或靠近所述第一瓶口111的方向,从而在操作的过程中,当所述可拆卸滤芯组件10从净水机上拆下的同时,限位件131在移动方向上的限位即可解除,继而能够将滤瓶盖12从滤瓶体11上旋拧拆下。整个拆卸过程流畅快捷,更换滤芯19更便利。
具体地,在一个实施例中,如图7和图8所示,可以在净水机的整机壳体30上设置锁紧凸起31。所述整机壳体30与滤芯安装座20连接。当所述可拆卸滤芯组件10与所述滤芯安装座20装配完成时,所述锁紧凸起31将所述限位件131抵触限定在所述锁紧位置,限制所述滤瓶盖12从所述第一瓶口111处松脱打开所述第一瓶口111。
或者,在另一实施例中,可以在所述净水机的整机壳体30上设置卡扣锁紧件。当所述可拆卸滤芯组件10与所述滤芯安装座20装配完成后,可以手动将所述限位件131推移至所述锁紧位置。当所述限位件131到达所述锁紧位置时,所述整机壳体30上的卡扣锁紧件与所述限位件131卡扣配合,避免限位件131移动退出所述锁紧位置。
具体地,所述限位件131可以与所述滤瓶体11滑动配合,或者所述限位件131与所述滤瓶盖12滑动配合。使得所述限位件131能够移动至所述锁紧位置,同时在一定情况下也能够退出所述锁紧位置。
例如,在一个实施例中,如图4所示,所述限位件131与所述滤瓶体11滑动配合,所述限位件131相对于所述滤瓶体11能够在远离所述第一瓶口111的方向上来回移动。
如图4所示,所述滤瓶体11为筒状结构,所述限位件131能够沿所述滤瓶体11的轴 向移动。
当所述限位件131移动至所述锁紧位置时,所述限位件131与所述滤瓶盖12之间的限位配合关系可以通过凹凸配合实现。具体地,可以在所述限位件131和所述滤瓶盖12两者中其中一者设置凸齿14,另一者设置齿槽16。当所述限位件131移动前进到锁紧位置时,所述凸齿14插入所述齿槽16中,限制所述滤瓶盖12相对于所述限位件131转动至所述滤瓶盖12松脱打开所述第一瓶口111的位置。当所述限位件131移动退出所述锁紧位置时,所述凸齿14退出所述齿槽16,所述滤瓶盖12可以相对于限位件131转动,进而能够将所述滤瓶盖12从所述滤瓶体11上旋下。
进一步地,所述限位件131相对于所述滤瓶体11在滤瓶体11周向上转动的自由度被限制,从而当所述滤瓶盖12无法相对于所述限位件131转动时,所述滤瓶盖12相对于滤瓶体11无法转动。这里所述的无法转动是指所述滤瓶盖12无法转动至将第一瓶口111打开的松脱位置,但是若滤瓶盖12转动较小角度时滤瓶盖12不会从第一瓶口111处松脱,则此小角度转动是允许的。
在一个实施例中,提供了一种滤瓶体单元,所述滤瓶体单元包括限位件131和滤瓶体11。如图3和图4所示,所述限位件131和所述滤瓶体11两者中其中一者设有导向凸起113,另一者设有导向槽133。所述导向凸起113位于所述导向槽133中,在滤瓶盖12旋拧方向上所述导向槽133的侧壁与所述导向凸起113之间间隙配合。
上述方案提供的一种滤瓶体单元,所述限位件131与所述滤瓶体11之间通过所述导向凸起113与所述导向槽133之间的配合,使得所述限位件131相对于所述滤瓶体11在所述滤瓶盖12旋拧方向上的转动受限制,从而当滤瓶盖12与限位件131之间通过凸齿14与齿槽16配合后,所述滤瓶盖12无法从所述滤瓶体11的第一瓶口111处旋拧松脱打开所述第一瓶口111,起到防漏水的效果。当滤瓶盖12旋拧到滤瓶体11上时,为了便于所述凸齿14与所述齿槽16配合,将所述导向槽133的侧壁与所述导向凸起113之间间隙配合,使得所述限位件131能够在所述滤瓶盖12旋拧的方向上可以转动一定小角度,以便凸齿14与齿槽16能够配合到一起,提高装配的便利性,同时降低对制造精度的要求。
在一个实施例中,如图1、图2和图4所示,所述滤瓶体11外设有所述导向凸起113。所述导向凸起113既可以作为所述限位件131相对于所述滤瓶体11滑动配合的基础,也可以作为避免限位件131从所述滤瓶体11上脱落的限位基础。
在一个实施例中,如图3、图4、图6和图7所示,所述限位件131覆盖在所述导向凸起113外。如图3所示,所述限位件131上朝向所述导向凸起113的面设有均沿所述滤 瓶体11轴向布置的第一限位筋134和第二限位筋135。所述第一限位筋134与所述第二限位筋135相对间隔设置,形成所述导向槽133。所述导向凸起113能够在所述导向槽133中沿所述滤瓶体11轴向滑动。在所述导向槽133的导向作用下,所述限位件131在所述滤瓶体11上能够沿所述滤瓶体11的轴向滑动至所述锁紧位置,也可以滑动脱离所述锁紧位置,在两种状态之间进行切换。
所述第一限位筋134和所述第二限位筋135构成所述导向槽133的两侧壁。在一个实施例中,当所述限位件131运动至所述锁紧位置,且所述凸齿14位于所述齿槽16中时,所述导向凸起113与所述第一限位筋134和/或第二限位筋135之间间隙配合。使得装配过程中,所述限位件131能够相对于所述滤瓶体11,在所述滤瓶盖12旋拧的方向上可以转动一定小角度,以便凸齿14与齿槽16能够配合到一起,提高装配的便利性,同时降低对制造精度的要求。
在一个实施例中,如图3所示,所述限位件131上面向所述滤瓶体11的侧面设有止退凸起136。如图4所示,所述导向凸起113限位于所述止退凸起136靠近所述第一瓶口111的一侧。从而避免所述限位件131从所述第一瓶口111所在这一端滑落。
在一个实施例中,为了避免所述限位件131从所述滤瓶体11的另一端滑落,如图1、图2和图4所示,所述滤瓶体11上面向所述限位件131的侧面设有防掉凸起114,所述防掉凸起114位于所述止退凸起136远离所述第一瓶口111的一侧。
在一个实施例中,如图4所示,在所述滤瓶体11的轴向上所述止退凸起136能够在所述防掉凸起114与所述导向凸起113之间移动。换言之,虽然所述防掉凸起114和所述导向凸起113分别限位在所述止退凸起136的两侧,但是所述防掉凸起114和所述导向凸起113之间的间距大于所述止退凸起136的厚度,使得所述止退凸起136能够在两者之间移动。
在一个实施例中,如图1和图2所示,所述防掉凸起114沿所述滤瓶体11周向环绕至少一周,提高防掉落的可靠性。无论所述止退凸起136在所述滤瓶体11周向如何分布,所述防掉凸起114均能够对其进行限位。而且,当所述防掉凸起114在所述滤瓶体11径向上的厚度足够时,所述防掉凸起114可以直接阻挡在所述限位件131的端面,防止所述限位件131从所述滤瓶体11上远离所述第一瓶口111的一端掉落。
在一个实施例中,如图4所示,当所述凸齿14插入所述齿槽16中时,所述止退凸起136与所述导向凸起113和防掉凸起114均间隔设置。确保所述导向凸起113和所述防掉凸起114的设置,不会限制所述凸齿14插入所述齿槽16中。
在一个实施例中,如图4所示,当所述凸齿14插入所述齿槽16中时,所述止退凸起136与所述防掉凸起114之间的间距大于所述凸齿14的高度。以确保所述限位件131能够向远离所述第一瓶口111的方向移动至所述凸齿14退出所述齿槽16。
在一个实施例中,当所述凸齿14插入所述齿槽16中时,所述止退凸起136与所述防掉凸起114之间的间距与所述凸齿14的高度之间的差值不小于1mm。
在一个实施例中,所述凸齿14可以设于所述限位件131上,所述齿槽16位于所述滤瓶盖12上;或者所述凸齿14位于所述滤瓶盖12上,所述齿槽16位于所述限位件131上。
如图3所示,在一个实施例中,所述凸齿14可以位于所述限位件131上靠近所述滤瓶盖12的部位。所述齿槽16成型于所述滤瓶盖12上朝向所述凸齿14的部位。或者,在另一个实施例中,所述凸齿14位于所述滤瓶盖12上靠近所述限位件131的部位,所述齿槽16成型于所述限位件131上朝向所述凸齿14的部位。
在一个实施例中,提供了一种滤芯锁紧单元,包括所述滤瓶体11、滤瓶盖12和限位件131。如图9和图10所示,所述齿槽16至少为两个,且多个齿槽16在所述滤瓶周向上依次布置,组成齿槽组15,所述凸齿14与所述齿槽组15对应配合。
在装配的过程中,只要所述凸齿14插入其中一个齿槽16中,即可限制所述滤瓶盖12从所述第一瓶口111处松脱打开,避免漏水的情况发生。设置多个齿槽16可允许齿槽16与凸齿14之间存在一定装配误差,降低对制造精度的要求,同时提高装配的便利性。
特别是,当所述凸齿14为多个,所述齿槽组15为多个。所述凸齿14与所述齿槽组15一一对应。所述齿槽组15包括在所述滤瓶周向上依次连接的多个齿槽16,使各个凸齿14均能够插入对应齿槽组15的齿槽16中。
在一个实施例中,如图3所示,所述凸齿14位于所述限位件131上靠近所述第一瓶口111的端面。如图9和图10所示,所述齿槽16位于所述滤瓶盖12上朝向所述凸齿14的端面。换言之,所述齿槽组15可以成型于所述滤瓶盖12上朝向所述限位件131的端面。当所述滤瓶盖12旋拧装配到所述滤瓶体11上后,所述限位件131移动至所述锁紧位置时,所述限位件131上设有所述凸齿14的端面朝向所述滤瓶盖12的端面,所述凸齿14位于所述齿槽16中。
可选的,所述凸齿14和所述齿槽16也可以设置在其他位置,只要当所述滤瓶盖12旋拧装配到所述滤瓶体11上后,所述限位件131移动至所述锁紧位置时,所述凸齿14能够插入所述齿槽16中即可。
在一个实施例中,如图1至图4所示,所述限位件131为环形结构。所述限位件131 套在所述滤瓶体11外,所述限位件131能够沿所述滤瓶体11的轴向滑动。从而所述限位件131能够可靠地装配在所述滤瓶体11上。
可选的,如图3所示,所述凸齿14为多个,多个所述凸齿14在所述限位件131的周向间隔布置。如图9所示,所述齿槽16为多个,每个所述凸齿14对应多个所述齿槽16。与同一凸齿14对应的多个齿槽16依次相连组成所述齿槽组15。所述齿槽组15为多个,多个齿槽组15在所述滤瓶盖12的周向上间隔布置。
当所述限位件131与所述滤瓶盖12限位配合在一起时,所述凸齿14与所述齿槽组15可以一一对应,增加所述滤瓶盖12相对于限位件131转动的阻力。
每个所述凸齿14对应的齿槽组15中可包括至少两个所述齿槽16。在装配的过程中,只要各个凸齿14插入对应的齿槽组15中的其中一个齿槽16即可。设置多个齿槽16可允许齿槽16与凸齿14之间存在一定装配误差,确保所有凸齿14能够同时插入各个齿槽组15中,降低对制造精度的要求,同时提高装配的便利性。
在一个实施例中,如图3所示,所述凸齿14为等腰三角形凸起结构,所述凸齿14的顶角为55°~65°。
所述凸齿14的顶角能够为凸齿14的插入过程起到导向作用。而且所述顶角角度为55°~65°,既保障了装配时良好的导向效果,同时也使得滤芯组件10的拆卸手感更佳。具体地,顶角小于55°时,齿距太小,不方便对位,凸齿14插入齿槽16的导向效果差;顶角大于65°时,可拆卸滤芯组件10从净水机的整机壳体30上拆装时,旋转力会通过凸齿14与齿槽16的配合斜面分解成可拆卸滤芯组件10拆装方向的力向外,加大滤瓶体11与滤芯安装座20旋扣的摩擦力,加大拆卸的力矩,影响拆卸手感。
在一个实施例中,所述凸齿14位于所述齿槽16中时,旋拧所述滤瓶使得凸齿14发生弹性变形脱离所述齿槽16的作用力为F1,将所述滤瓶体11从滤芯安装座20上拧松的作用力为F2,F1大于F2。确保拆卸过程中,作用在所述滤瓶上的力首先将所述滤瓶体11从所述滤芯安装座20上卸下,而不是将凸齿14旋出齿槽16。
为了保障凸齿14与齿槽16之间的配合,所提供的阻力足够,在一个实施例中,将所述凸齿14高度设置为3mm~5mm。
进一步地,当所述限位件131运动至所述锁紧位置,且所述凸齿14位于所述齿槽16中时,所述导向凸起113与所述第一限位筋134和/或第二限位筋135之间隙配合,便于在装配的过程中使得所述凸齿14能够顺利插入对应的齿槽组15中。但所述导向凸起113与所述第一限位筋134和/或第二限位筋135之间的间隙不能过大,否则所述第一限位筋134 和所述第二限位筋135将丧失限位导向作用,凸齿14容易脱离对应齿槽组15。
因此,在一个实施例中,所述导向凸起113与所述第一限位筋134之间的间隙宽度小于所述凸齿14移出对应齿槽组15所需转动的周向距离。即,虽然所述限位件131能够在所述滤瓶体11的周向上稍微转动,但是其转动角度受到限制,确保所述凸齿14始终对位于对应的齿槽组15,而不会偏离,确保所述限位件131对所述滤瓶盖12的限位功能不会丧失。
进一步地,在一个实施例中,一个齿槽组15中包括2n+1个齿槽16,其中n为整数。即,一个齿槽组15所包含的齿槽16的个数为奇数。所述齿槽组15的齿距为h。当所述凸齿14位于本齿槽组15中最中间这个齿槽16中时,所述导向凸起113与所述第一限位筋134和第二限位筋135之间均间隙配合,且所述导向凸起113与所述第一限位筋134和所述第二限位筋135之间的间隙宽度均为d,0.5h<d≤(n+0.5)h。
在所述第一限位筋134和所述第二限位筋135的限位作用下,即使所述导向凸起113在两者之间晃动,但其间隙宽度大小使得所述凸齿14始终与齿槽组15相对,而不会偏离。
在一个实施例中,如图9和图10所示,所述齿槽组15包括3个齿槽16。当所述凸齿14位于本齿槽组15中最中间这个齿槽16中时,所述导向凸起113与所述第一限位筋134和第二限位筋135之间均间隙配合,且所述导向凸起113与所述第一限位筋134和所述第二限位筋135之间的间隙宽度均为d,0.5h<d≤1.5h。
在一个实施例中,如图3所示,所述限位件131为环形结构。所述导向凸起113为多个,多个所述导向凸起113在所述滤瓶体11的周向间隔布置。所述导向槽133为多个,多个所述导向槽133沿所述限位件131的周向间隔布置。所述导向凸起113与所述导向槽133一一对应。换言之,所述第一限位筋134、第二限位筋135和弹扣132组成限位组,则所述限位组为多个,多个所述限位组在所述限位件131的周向上间隔布置。
在一个实施例中,如图3所示,所述凸齿14位于所述第一限位筋134与所述第二限位筋135之间。
所述凸齿14可在周向上正对的位于所述第一限位筋134与所述第二限位筋135之间。对于所述凸齿14位于所述限位件131端面的实施例而言,所述凸齿14位于所第一限位筋134的延长线和所述第二限位筋135的延长线之间。
另外,当所述凸齿14设于所述滤瓶盖12上时,在所述凸齿14插入所述齿槽16中时,所述凸齿14在周向上正对的位于所述第一限位筋134与所述第二限位筋135之间。
在一个实施例中,如图3所示,所述限位件131上位于所述第一限位筋134与所述第 二限位筋135之间的部分为弹扣132。所述止退凸起136位于所述弹扣132的内侧面,所述弹扣132可被向外挤压发生弹性变形。
装配过程中,所述限位件131沿所述滤瓶体11轴向移动,使得所述止退凸起136从所述导向凸起113靠近所述第一瓶口111的一侧移动到另一侧,在此过程中所述弹扣132发生弹性变形以便所述止退凸起136越过所述导向凸起113。当所述止退凸起136到达所述导向凸起113远离所述第一瓶口111的一侧后,所述弹扣132复位,使得所述止退凸起136被所述导向凸起113限位在远离所述第一瓶口111的一侧,而避免限位件131从第一瓶口111这一端掉落。
特别是当所述限位件131为环形结构时,只要能够阻止所述限位件131从所述滤瓶体11两端滑落,所述限位件131则不会从所述滤瓶体11上脱落,有效避免限位件131丢失的情况发生。
在一个实施例中,如图3所示,提供了一种限位环13,包括所述限位件131,所述限位件131为环形结构,所述限位件131的内侧面设有均沿所述限位件131轴向布置的第一限位筋134和第二限位筋135。所述限位件131上位于所述第一限位筋134与所述第二限位筋135之间的部位为弹扣132。所述弹扣132的内侧面设有止退凸起136,所述弹扣132可被向外挤压发生弹性变形。
装配时可以将所述限位环13套在滤瓶体11外,基于所述弹扣132具有弹性变形能力。因此可以通过沿滤瓶体11轴向推移限位环13使得止退凸起136位于导向凸起113远离第一瓶口111的一侧。并且导向凸起113也位于第一限位筋134与第二限位筋135之间,限制所述限位环13相对于所述滤瓶体11在周向上的转动。一次对位装配过程完成多个方位的限制,提高装配的便利性。
在一个实施例中,如图3所示,所述限位件131上设有所述第一限位筋134的部位与所述弹扣132之间具有缺口,所述限位件131上设有所述第二限位筋135的部位与所述弹扣132之间具有缺口。所述弹扣132只有一边与所述限位件131连接,使得所述弹扣132具有一定弹性变形能力。
在一个实施例中,如图3所示,所述缺口贯穿所述限位件131的第一端面。所述止退凸起136位于所述弹扣132上靠近所述第一端面的位置。所述弹扣132上用于与限位件131连接的这一端为固定端。所述弹扣132上远离所述固定端的一端为自由端。所述止退凸起136位于所述弹扣132的自由端。装配的过程中,所述弹扣132发生弹性变形,使得所述止退凸起136越过所述导向凸起113,并被所述导向凸起113限位在远离所述第一瓶口111 的一侧。
在一个实施例中,如图3和图4所示,所述凸齿14或齿槽16位于所述限位件131的第二端面。所述限位件131装配到所述滤瓶体11上时,第一端面朝向滤瓶体11远离第一瓶口111的一端,第二端面面向所述滤瓶盖12。当所述滤瓶盖12旋拧到所述滤瓶体11上的过程中,凸齿14刚好插入齿槽16中。
当图3所示限位环13装配到图4所示角度可拆卸滤芯组件10的滤瓶体11上时,所述第一端面朝下,所述第二端面朝上。
在一个实施例中,如图3所示,所述限位件131为环形结构。所述限位件131的第二端面设有凸齿14或齿槽16。所述凸齿14或齿槽16对位于所述第一限位筋134和所述第二限位筋135之间。所述止退凸起136位于所述弹扣132上靠近所述第一端面的部位。装配过程中,所述导向凸起113被限位于所述第一限位筋134、第二限位筋135之间,且所述止退凸起136越过所述导向凸起113后,所述限位件131上凸齿14(或齿槽16)的位置刚好与滤瓶盖12上齿槽16(或凸齿14)对应。将凸齿14或齿槽16与弹扣132、第一限位筋134和第二限位筋135临近设置,能够有效提高装配精度。
在另一个实施例中,所述限位件131与所述滤瓶盖12滑动配合,滑动方向为所述滤瓶盖12的轴向。换言之,所述限位件131设置在所述滤瓶盖12上,所述限位件131跟随所述滤瓶盖12一起初步装配到滤瓶体11上,然后相对于所述滤瓶盖12移动所述限位件131使得所述限位件131运动至所述锁紧位置。当所述限位件131到达所述锁紧位置时,所述限位件131与所述滤瓶体11之配合限位,使得所述滤瓶体11相对于所述限位件131无法转动,进而使得所述滤瓶盖12无法送所述第一瓶口111松脱。
具体地,所述限位件131和所述滤瓶体11两者中其中一者可设有凸齿14,另一者可设有齿槽16。当所述限位件131移动前进到锁紧位置时,所述凸齿14插入所述齿槽16中,限制所述滤瓶体11相对于所述限位件131转动。当所述限位件131移动退出所述锁紧位置时,所述凸齿14退出所述齿槽16,使得所述滤瓶盖12和所述限位件131能够一起从所述滤瓶体11上卸下,进而将所述滤瓶体11中的滤芯19取出更换掉。
进一步具体地,所述限位件131位于所述滤瓶盖12的外侧面,所述凸齿14位于所述滤瓶体11的外侧面,所述限位件131上朝向所述凸齿14的部位设有所述齿槽16。
在一个实施例中,所述滤瓶体11上凸齿14的齿尖可以沿所述滤瓶体11的径向朝外。所述限位件131为环形结构。所述齿槽16位于所述限位件131的内侧面。所述限位件131移动至所述锁紧位置时,所述限位件131上设有所述齿槽16的部位套在所述滤瓶体11上 设有所述凸齿14的部位外,所述凸齿14位于所述齿槽16中。
当所述凸齿14为等腰三角形凸起结构时,所述凸齿14的顶角处即为所述凸齿14的齿尖。在如图3所示限位环13所在实施例中,当限位环13在装配到滤瓶体11上时,所述凸齿14的齿尖是沿所述滤瓶体11的轴向朝向所述滤瓶盖12。
可选地,所述凸齿14也可以位于所述限位件131上,所述齿槽16位于所述滤瓶体11上。
在一个实施例中,所述限位件131为环形结构,所述限位件131套在所述滤瓶盖12外,所述限位件131能够沿所述滤瓶盖12的轴向滑动。所述凸齿14为多个,多个所述凸齿14沿所述滤瓶体11的周向间隔布置。所述齿槽16为多个,每个所述凸齿14对应多个所述齿槽16,与同一凸齿14对应的齿槽16依次连接组成齿槽组15,多个齿槽组15在所述限位件131的周向上间隔布置。
与将限位环13滑动设置在滤瓶体11上的方案类似,上述限位件131套在滤瓶盖12外。齿槽组15的设置,能够降低装配过程中对限位件131和滤瓶体11之间的对位精度要求,只要凸齿14插入对应齿槽组15中的一个齿槽16中即可。
在一个实施例中,如图4所示,所述可拆卸滤芯组件10还包括端盖17,所述端盖17与所述滤瓶盖12连接。所述端盖17位于所述滤瓶盖12所围空间内。当所述滤瓶盖12装配到所述滤瓶体11的第一瓶口111处时,所述端盖17跟随所述滤瓶盖12一起移动,而插入所述滤瓶体11中且将所述第一瓶口111封堵。
拆卸的过程中,当所述限位环13与所述滤瓶盖12之间的限位解除后,将所述滤瓶盖12从所述滤瓶体11上旋拧拆下的过程中,所述端盖17随所述滤瓶盖12一起移动,使得所述端盖17从所述滤瓶体11中抽出,进而更换所述滤瓶体11中的滤芯19。
可选的,如图4所示,所述端盖17与所述滤瓶体11的第一瓶口111处的内壁之间设有第一密封圈171,确保所述端盖17插入所述滤瓶体11中后能够将所述第一瓶口111可靠封堵。
在一实施例中,当所述滤瓶盖12相对于滤瓶体11旋转的过程中,如果所述端盖17相对于所述滤瓶体11转动,会导致旋拧过程阻力较大,拆卸不够便利。为避免该情况发生,在一个实施例中,如图4、图5、图12和图13所示,所述可拆卸滤芯组件10还包括连接件18。端盖17通过连接件18与所述滤瓶盖12的底壁可活动连接,使得滤瓶盖12在转动时不会带动端盖17转动。在所述滤瓶盖12装配到所述滤瓶体11上的过程中,所述滤瓶盖12的底壁能够挤压所述端盖17,使得所述端盖17插入所述滤瓶体11内。在所述滤瓶盖 12从所述滤瓶体11上拆下的过程中,所述滤瓶盖12能够通过所述连接件18将所述端盖17从所述滤瓶中拔出。
如图4、图5和图12所示,在一个实施例中,所述滤瓶盖12的底壁内侧面设有安装体121。如图12和图13所示,所述端盖17上朝向所述滤瓶盖12底壁的面为第三端面173,所述端盖17上朝向所述滤瓶体11内的端面为第四端面174。如图13所示,所述端盖17设有安装孔175,所述安装孔175贯穿所述端盖17的第三端面173和第四端面174。所述安装体121插于所述安装孔175中,所述端盖17能够相对于所述安装体121转动。如图4和图5所示,所述连接件18一端与所述安装体121连接,所述连接件18另一端与所述端盖17限位配合,用于限制所述端盖17相对于所述连接件18在所述滤瓶盖12轴向上移动。连接件18另一端与端盖17在轴向上部分重合。从而,当所述滤瓶盖12相对于所述滤瓶体11转动时,所述端盖17不会跟随所述滤瓶盖12转动,但是所述端盖17会随所述滤瓶盖12在所述滤瓶盖12轴向上移动。
具体地,如图5所示,所述连接件18为螺钉,所述螺钉设置在所述安装体121中。所述螺钉的螺帽与所述端盖17限位配合,限制所述端盖17相对于所述连接件18在所述滤瓶盖12轴向上移动。但所述螺帽与所述安装孔175的侧壁间隔设置,从而使得所述端盖17不会随所述滤瓶盖12转动。
进一步具体地,如图12所示,所述端盖17的侧壁与所述滤瓶盖12的侧壁之间间隔设置,从而当所述端盖17插入所述滤瓶体11中时,所述滤瓶盖12的侧壁套在所述滤瓶体11外。
如图5和图12所示,在一个实施例中,所述连接件18上用于与所述端盖17限位配合的一端为限位端181。所述安装孔175的内壁设有限位凸起176。所述限位凸起176限位于所述限位端181靠近所述第三端面173的一侧,从而限制所述端盖17相对于所述连接件18在所述滤瓶盖12轴向上的移动。当所述连接件18为所述螺钉时,所述限位端181为所述螺钉的螺帽,所述螺钉的螺帽位于所述限位凸起176远离所述第三端面173的一侧。
具体地,如图5所示,所述限位凸起176为多个,多个所述限位凸起176在所述安装孔175的周向上间隔布置。或者所述限位凸起176为沿所述安装孔175周向布置的环形凸起。所述限位凸起176所围空间的孔径小于所述限位端181的外径,从而将所述限位端181限制在所述限位凸起176远离所述第三端面173的一侧。
可选的,如图13所示,所述限位凸起176上靠近所述限位端181的端面设有抵接凸起177,所述抵接凸起177与所述限位端181抵接,减小所述滤瓶盖12转动时所述连接件 18与所述端盖17之间的摩擦力。具体地,所述抵接凸起177为多个,多个所述抵接凸起177在所述安装孔175的周向上间隔布置。
在一个实施例中,所述限位端181与所述限位凸起176之间还设有垫片(图中未示出),进一步降低旋转所述滤瓶盖12时所述端盖17间接施加在所述滤瓶盖12上的摩擦力。
在一实施例中,如图5所示,所述安装体121与所述安装孔175的侧壁之间设有第二密封圈172。避免所述滤瓶体11中的液体从所述安装体121与所述安装孔175之间的缝隙泄漏。所述第二密封圈172位于所述限位凸起176靠近所述第三端面173的一侧,从而所述限位凸起176能够有效避免所述第二密封圈172从所述安装体121上远离所述滤瓶盖12底壁的一端脱落。
为了提高所述第二密封圈172在所述安装体121上限位位置的稳定性,如图5和图10所示,可以将所述安装体121在所述滤瓶盖12轴向上分为第一段和第二段。所述第一段连接在所述第二段与所述滤瓶盖12的底壁之间,所述第一段的外径大于所述第二段的外径,在所述安装体121的外侧面形成台阶。所述第二密封圈172套在所述第二段外,所述第一段限位于所述第二密封圈172靠近所述第三端面173的一侧。结合所述限位凸起176和所述第一段,所述第二密封圈172在所述安装体121上的位置被限定,确保所述第二密封圈172的密封有效性。
如图10和图12所示,所述滤瓶盖12的底壁内侧面设有支撑件122,所述支撑件122位于所述安装体121与所述滤瓶盖12的侧壁之间,所述支撑件122与所述端盖17抵接,用于避免所述端盖17承压变形断裂。具体地,所述支撑件122可以为支撑筋条。
在另一个实施例中,提供了一种净水机,包括上述任一实施例中所述的滤芯锁紧单元。通过采用上述任一实施例中所述的滤芯锁紧单元,从而在更换滤芯19后组装的过程中,只用将所述滤瓶盖12旋拧到所述凸齿14插入其中一个齿槽16中即可,允许一定装配误差,降低对制造精度的要求,同时提高装配的便利性。
在另一个实施例中,提供了一种净水机,包括上述任一实施例中所述的滤瓶体单元。基于所述导向凸起113与所述导向槽133的侧壁之间具有间隙,从而使得限位件131能够相对于滤瓶体11在一定角度内转动,便于凸齿14与齿槽16配合到一起,提高装配的便利性,同时降低对制造精度的要求。
在一个实施例中,提供了一种净水机,包括上述任一实施例所述的可拆卸滤芯组件10。
通过采用上述任一实施例中所述的可拆卸滤芯组件10,从而在避免拆卸更换滤芯19时漏水情况发生的同时提高更换滤芯19的便利性。
在一个实施例中,如图2所示,所述净水机还包括滤芯安装座20,所述滤瓶体11旋扣在所述滤芯安装座20上,所述滤瓶体11旋扣的方向与所述滤瓶盖12旋拧到所述滤瓶体11上的旋转方向一致,所述滤瓶体11的第二瓶口112与所述滤芯安装座20连通。
滤瓶体11的两端的瓶口分别为第一瓶口111和第二瓶口112,所述滤瓶中的滤芯19经过所述第二瓶口112与所述滤芯安装座20上的各个水口导通。所述滤瓶盖12可拆卸的装配在所述滤瓶体11的第一瓶口111处。基于所述滤瓶体11旋扣的方向与所述滤瓶盖12旋拧到所述滤瓶体11上的旋转方向一致,因此为了避免拆卸过程中,出现滤瓶体11与滤芯安装座20未脱离,而所述滤瓶盖12先松动的情况。而进一步设置所述限位件131,利用所述限位件131作为中间元件,既能避免滤瓶盖12先松动漏水的情况发生,也能够在滤瓶体11与滤芯安装座20之间脱离后,顺利取下所述滤瓶盖12。
在一个实施例中,如图7和图8所示,所述净水机还包括整机壳体30,所述滤芯安装座20与所述整机壳体30连接,所述整机壳体30上设有锁紧凸起31,当所述可拆卸滤芯组件10与所述滤芯安装座20装配完成时,所述锁紧凸起31将所述限位件131抵触限定在所述锁紧位置。
当所述限位件131滑动配合在所述滤瓶体11上时,所述滤瓶体11与所述滤芯安装座20装配完成后,所述滤瓶体11与锁紧凸起31之间的相对位置固定,所述锁紧凸起31将所述限位件131抵触限定在所述锁紧位置。
在拆卸的过程中,当所述滤瓶体11未从所述滤芯安装座20上卸下时,所述锁紧凸起31一直将所述限位件131限定在所述锁紧位置,随着所述滤瓶体11逐渐从所述整机壳体30中抽出,所述限位件131逐渐脱离所述锁紧凸起31,此时可以将所述限位件131向远离所述第一瓶口111的方向推移,使得所述限位件131退出所述锁紧位置,凸齿14退出所述齿槽16。
在一个实施例中,所述滤瓶中安装有滤芯19,如图11所示,所述滤芯19包括芯体和内筒191,所述芯体设置在所述内筒191中。所述内筒191与所述滤瓶间隔设置,所述内筒191上靠近所述第一瓶口111的部位设有把手193。
当所述滤瓶盖12从所述滤瓶体11上卸下后,通过所述把手193将所述滤芯19从所述滤瓶体11中抽出,然后将所述内筒191中的芯体更换后,将更换有新芯体的滤芯19装入所述滤瓶中。
如图11所示,所述内筒191上设有冲洗排水孔192。当通过冲洗即可对所述滤芯19进行清理使其恢复净水能力时,可以先不用更换滤芯19。此时可以将冲洗水从所述可拆卸 滤芯组件10的原水进口和/或纯水出口注入所述滤芯19中,对所述滤芯19中的芯体进行冲洗,冲洗的污水则从所述内筒191上的冲洗排水孔192排至所述内筒191与所述滤瓶体11之间的间隙,然后从所述滤瓶体11上的浓水排水口排出所述滤瓶体11外。
