Description

一种可单独更换过滤组件的滤芯
技术领域
本发明涉及一种滤芯。
背景技术
众所周知，滤芯主要是依靠其内部的过滤体来过滤液体。当过滤体使用一段时间后，该过滤体不能再过滤液体中的杂质，用户则需要更换新的滤芯。
现有的滤芯的过滤体一般是由多层过滤组件所构成，该些过滤组件有些是用于吸附液体中的杂质，有些是用于限制液体中的杂质不能穿过该过滤组件，不同的过滤组件具有不同的使用寿命，而现有的过滤体一般是做成一整体的，因而使用寿命最短的过滤组件则决定了过滤体的使用寿命。
当使用寿命最短的过滤组件到达使用极限时，用户需要更换滤芯的整个过滤体，而被更换掉的过滤体中还有一部分过滤组件还可以长时间使用的，更换整个过滤体，既增加了用户的使用成本，同时也导致还能够继续长时间使用的过滤组件被扔掉，造成资源浪费。
发明内容
为了解决上述问题，本发明的目的在于提供一种结构简单，同时可以单独更换过滤组件的滤芯。
本发明为解决其技术问题而采用的技术方案是：
一种可单独更换过滤组件的滤芯，包括一带有敞口的容腔的外壳，所述容腔中设置有过滤体，同时该容腔的敞口处还可拆卸设置有一能够封堵该敞口的盖板，所述外壳上还分别开设有供原水流入的进水口、供过滤后的废水流出的废水出口和供过滤后的液体流出的净水出口，所述过滤体至少由两个相互独立的过滤组件相互套接而形成。
作为上述技术方案的改进，所述过滤体由三个相互独立的过滤组件相互套接而形成，该过滤体从外至内依次为外侧过滤组件、中间过滤组件和内侧过滤组件。
作为上述技术方案的进一步改进，所述外侧过滤组件、中间过滤组件和内侧过滤组件分别为碳棒、RO膜和碳棒。
在本发明中，所述外侧过滤组件、中间过滤组件和内侧过滤组件分别为折纸过滤层、RO膜和碳棒。
优选地，所述外侧过滤组件的上下端面处分别设置有一能够防止液体从该外侧过滤组件的两端进入其内部的外侧上端盖和外侧下端盖。
进一步，所述内侧过滤组件的上下端面处分别设置有一能够防止液体从该内侧过滤组件的两端进入其内部的内侧上端盖和内侧下端盖，所述内侧上端盖或内侧下端盖上开设有与所述净水出口相连通的净水通道。
再进一步，所述盖板朝向所述容腔的一侧表面上还设置有一便于所述中间过滤组件插装在其内的凹槽。
本发明的一优选实施例，所述进水口和废水出口设置于所述盖板上且该进水口和废水出口分别位于所述凹槽的外部和内部，同时所述净水出口则设置于所述容腔的底壁上。
本发明的有益效果是：由于本发明通过采用两个以上相互独立的过滤组件相互套接形成过滤体，因此本发明的滤芯可以单独更换其中某部分使用寿命到达极限的过滤组件，而不用更换整个过滤体，既可以降低用户使用滤芯的成本，同时也可以防止使用寿命未到达极限的过滤组件被弃置，节约了社会资源。
附图说明
下面结合附图和具体实施方式对本发明作进一步详细的说明。
图1是本发明一优选实施例的外观结构示意图；
图2是本发明一优选实施例的另一个角度的外观结构示意图；
图3是本发明一优选实施例的内部结构示意图；
图4是本发明一优选实施例的局部结构分解示意图；
图5是本发明一优选实施例的结构分解示意图。
具体实施方式
参照图1至图 5(图3中箭头的方向表示液体流动的方向)，一种可单独更换过滤组件的滤芯，包括一带有敞口的容腔11的外壳10，所述容腔11中设置有过滤体20，同时该容腔11的敞口处还可拆卸设置有一能够封堵该敞口的盖板12，在这里，优选地，所述盖板12通过螺纹连接于所述容腔11的敞口处，当然上述的盖板12还可以通过卡接方式安装于所述外壳10上，也是可以的；所述外壳10上还分别开设有供原水流入的进水口13、供过滤后的废水流出的废水出口14和供过滤后的液体流出的净水出口15，所述过滤体20至少由两个相互独立的过滤组件相互套接而形成。
由于本发明通过采用两个以上相互独立的过滤组件相互套接形成过滤体，因此本发明的滤芯可以单独更换其中某部分使用寿命到达极限的过滤组件，而不用更换整个过滤体，既可以降低用户使用滤芯的成本，同时也可以防止使用寿命未到达极限的过滤组件被弃置，节约了社会资源。
在这里，为了使得本发明的过滤器的过滤效果更好，优选地，所述过滤体20由三个相互独立的过滤组件相互套接而形成，该过滤体20从外至内依次为外侧过滤组件21、中间过滤组件22和内侧过滤组件23，在本发明中，所述外侧过滤组件21、中间过滤组件22和内侧过滤组件23分别为碳棒、RO膜和碳棒；另外，上述的外侧过滤组件21、中间过滤组件22和内侧过滤组件23还可以为其他过滤组件，如：所述外侧过滤组件21、中间过滤组件22和内侧过滤组件23分别为折纸过滤层、RO膜和碳棒，当然上述的外侧过滤组件21、中间过滤组件22和内侧过滤组件23采用其他过滤材料制造也是可以的。通过将本发明的滤芯的过滤体20设置为外侧过滤组件21、中间过滤组件22和内侧过滤组件23，因此待过滤的液体依次穿过外侧过滤组件21、中间过滤组件22和内侧过滤组件23时，可以过滤得更加彻底，过滤效果更好。
为了使得待过滤的液体可以依次穿过外侧过滤组件21、中间过滤组件22和内侧过滤组件23，优选地，所述外侧过滤组件21的上下端面处分别设置有一能够防止液体从该外侧过滤组件21的两端进入其内部的外侧上端盖211和外侧下端盖212，在这里，所述外侧上端盖211和外侧下端盖212通过密封圈分别与容腔11的底部内壁以及盖板12的底部内壁密封相连接，通过设置上述的外侧上端盖211和外侧下端盖212，可以使得待过滤的水必须先穿过外侧过滤组件21才能接触到位于其内部的中间过滤组件22和内侧过滤组件23。
进一步，为了使得液体必须穿过中间过滤组件22并被该中间过滤组件22所过滤，在本发明中，所述盖板12朝向所述容腔11的一侧表面上还设置有一便于所述中间过滤组件22插装在其内的凹槽120，安装时，所述中间过滤组件22插装于该凹槽120中，同时中间过滤组件22的两端通过密封圈分别与所述容腔11的底部内壁和所述凹槽120的内壁密封相连接，因此待过滤的液体必须穿过中间过滤组件22才能接触到位于其内部的内侧过滤组件23。
进一步，为了使得液体必须经过所述内侧过滤组件3的过滤才能流动至净水出口处，在本发明中，所述内侧过滤组件23的上下端面处分别设置有一能够防止液体从该内侧过滤组件23的两端进入其内部的内侧上端盖231和内侧下端盖232，所述内侧上端盖231或内侧下端盖232上开设有与所述净水出口15相连通的净水通道233，所述净水通道233与所述净水出口15之间通过密封圈进行密封，因此只有穿过所述内侧过滤组件3的液体才能通过所述净水通道233进入到净水出口15处，保证净水出口15处流出的液体是经过多重过滤的，保证过滤质量。
再进一步，为了使得本发明的滤芯的结构更加合理，在这里，优选地，所述进水口13和废水出口14设置于所述盖板12上且该进水口13和废水出口14分别位于所述凹槽120的外部和内部，同时所述净水出口15则设置于所述容腔11的底壁上。当然，上述的净水出口15、进水口13和废水进口14也可以设置于外壳10的不同位置处。
以上所述仅为本发明的优先实施方式，只要以基本相同手段实现本发明目的的技术方案都属于本发明的保护范围之内。
