根据本发明一个实施例的净水机，包括：机壳(未示出)、水路板(未示出)和滤芯组件100，水路板和滤芯组件100可以设在机壳内，水路板连通滤芯组件100为滤芯组件100供水，并将滤芯组件100过滤后的水引出供用户使用。
首先，参考附图描述根据本发明实施例的滤芯组件100的一些具体实施例。
如图1和3所示，根据本发明一个实施例的滤芯组件100，包括：壳体10、滤芯接座20和滤芯30，壳体10内限定出过滤腔，过滤腔的一侧表面(如图3所示的上端面)敞开形成滤芯安装口，为滤芯30安装提供方便，壳体10上形成有与过滤腔连通的通水口11，通水口11沿壳体10的壁面(如图3所示的底壁)的厚度贯穿壳体10的底壁面，滤芯接座20安装在壳体10上且在正交于通水口11的轴向的平面内相对于壳体10可移动，也就是说，滤芯接座20相对于壳体10沿通水口11的径向移动。
其中，滤芯30设在过滤腔内且通过通水口11与滤芯接座20可拆卸地相连，具体而言，滤芯接座20连接在壳体10上，并罩设在通水口11上，滤芯30的一部分可以穿过通水口11从过滤腔伸出，且滤芯30伸出过滤腔的部分与滤芯接座20可拆卸地相连。
由此，根据本发明实施例的滤芯组件100，滤芯接座20设在壳体10上并沿通水口11的径向移动，在滤芯30安装过程中，通过调节滤芯接座20的位置确保滤芯30与滤芯接座20适配连接并达到最优的连接效果，不仅为滤芯30的安装提供了方便，还能防止因滤芯30偏移影响滤芯30与滤芯接座20的连接密闭性，而且消除了滤芯30与滤芯接座20错位对滤芯30造成的损伤，再者，滤芯接座20的结构简单，生产成本较低。
根据本发明实施例的净水机，通过采用上述实施例的滤芯组件100，能够为用户拆卸清理或更换滤芯30提供方便，有利于保证净水机的净水效果。
下面参考图1-图9描述根据本发明实施例的滤芯组件100的一些具体实施例。
如图5和6所示，根据本发明的一个实施例，壳体10的底部设有安装柱 12，安装柱12的中心轴线平行于通水口11的轴向，滤芯接座20对应安装柱12的位置设有安装孔211，安装柱12配合插接在安装孔211内，且安装柱12的横截面积小于安装孔211的横截面积，滤芯接座20安装在壳体10上时，安装柱12的外周壁与安装孔211的内周壁之间仍具有一定的间隙，滤芯接座20能够相对于壳体10移动。
其中，利用安装柱12与安装孔211适配连接滤芯接座20和壳体10，结构简单，安装方便，生产成本较低，不仅能够放置滤芯接座20与壳体10脱离，还能保证滤芯接座20与壳体10的相对错动，为滤芯30与滤芯接座20连接提供方便。
如图9所示，根据本发明的一个实施例，安装孔211贯通滤芯接座20，安装柱12的长度大于安装孔211的长度，具体而言，安装柱12从安装孔211的一端(如图3所示的上端)伸入安装孔211，且安装柱12的一部分从安装孔211的另一端(如图3所示的下端)伸出，保证安装柱12的下端面低于安装孔211的底部。
由此，滤芯接座20安装在壳体10上时，由于安装柱12的横截面积小于安装孔211的横截面积，且安装柱12的长度大于安装孔211的长度，进一步提升了滤芯接座20相对于壳体10的自由度，滤芯接座20不仅能够在正交于通水口11的轴向的平面内移动，还能在通水口11的轴向方向上移动，防止因安装柱12长度过短造成滤芯接座20无法移动的情况发生。
如图2所示，根据本发明的一个具体实施例，安装柱12的远离壳体10的一端设有用于止挡滤芯接座20脱出安装柱12的止挡件122，止挡件122连接在安装柱12伸出安装孔211的一端，防止滤芯接座20沿通水口11的轴向脱离安装柱12，而且通过增加对滤芯接座20在通水口11的轴向方向上的限定作用，增加滤芯接座20与滤芯30在通水口11轴向上的作用力，进而提升了滤芯接座20与滤芯30之间的连接密闭性，防止水流泄露。
进一步地，如图6所示，安装柱12的远离壳体10的一端的端面上设有螺 纹孔121，止挡件122为配合在螺纹孔121内的螺纹紧固件，螺纹紧固件可以是螺钉，螺钉的螺柱部分连接在螺纹孔121内，螺钉的头部的直径大于安装孔211的内径，螺纹紧固件也可以是螺栓，螺栓的螺柱连接在螺纹孔121内，螺栓的头部的直径大于安装孔211的内径。
螺纹紧固件的结构简单，可以根据安装柱12和安装孔211的尺寸选择合适的螺纹紧固件，防止滤芯接座20脱落，降低了滤芯组件100的生产成本，而且螺纹紧固件的安装与拆卸工艺简单，为滤芯组件100的装配与维护提供了方便。
如图9所示，根据本发明的一个实施例，安装孔211的横截面可以是圆形(如图9所示，在本实施例中，安装孔211的横截面为圆形)也可以是椭圆形，且安装柱12的横截面的形状与安装孔211的横截面的形状适配，由此，不仅为滤芯接座20与壳体10的安装提供了方便，还能保证安装柱12与安装孔211之间具有一定的活动间隙。
如图6所示，在本实施例中，安装柱12为多个(如图6所示的4个)且沿通水口11的周向等间距设置，安装孔211为多个且与安装柱12的数量相同，多个安装柱12分别配合在多个安装孔211内，一方面，通过设置多个安装柱12与安装孔211，能够提升滤芯接座20与壳体10之间的连接稳定性，另一方面，安装孔211沿通水口11的周向均匀间隔开布置，保证滤芯接座20受力均匀，能够提升滤芯接座20与滤芯30的连接密闭性，防止滤芯接座20与滤芯30之间受力不均造成水流泄露。
在一些具体实施例中，滤芯30与壳体10的内壁面之间设有锁止件，锁止件用于将滤芯30固定在过滤腔内，不仅能够提升滤芯30在过滤腔内的稳定性，防止滤芯30晃动，还能提升滤芯30与壳体10的连接强度，防止滤芯30从过滤腔中脱离，而且锁止件简化了滤芯30与壳体10之间的连接结构，为用户更换或维护滤芯30提供了方便。
如图6所示，在本实施例中，滤芯30包括：滤芯本体31和滤芯接头32，滤芯本体31和滤芯接头32均沿通水口11的轴向延伸，且滤芯本体31的下端 和滤芯接头32的上端相连，滤芯本体31设在过滤腔内，滤芯接头32穿过通水口11与滤芯接座20可拆卸地相连，通过在滤芯本体31与滤芯接座20之间设置滤芯接头32，不仅能够为滤芯30与滤芯接座20之间的连接提供方便，还能提升滤芯30与滤芯接座20之间的连接密闭性，防止水流泄露。
进一步地，如图9所示，滤芯接座20包括：接座本体21、进水管22和出水管23，接座本体21的朝向壳体10的表面上设有安装槽212，滤芯接头32可拆卸地安装在安装槽212内，滤芯接头32的外周壁与安装槽212的内周壁密闭配合，进一步提升了滤芯接座20与滤芯30的连接密闭性，进水管22和出水管23设在接座本体21上且分别通过安装槽212与滤芯接头32连通，进水管22和出水管23连通滤芯接头32，方便水路板为滤芯30供水或引出滤芯30过滤后干净水流。
如图6所示，在本实施例中，滤芯接头32包括第一接头321和套设在第一接头321外的第二接头322，第一接头321的下端形成圆形进水口，第二接头322与第一接头321之间形成环形出水口，安装槽212包括第一凹槽2121和套设在第一凹槽2121外的第二凹槽2122，第一凹槽2121的横截面形成为圆形，第二凹槽2122的横截面形成为与第一凹槽2121同心的圆环形，第一接头321插接在第一凹槽2121内且第二接头322插接在第二凹槽2122内，其中，第一接头321和第二接头322分别与第一凹槽2121和第二凹槽2122配合，一个用于进水另一个用于出水，例如，当第一接头321和第一凹槽2121可以用于进水时，第一凹槽2121连通进水管22，第二接头322和第二凹槽2122用于出水，且第二凹槽2122连通出水管23，类似的，第二接头322和第二凹槽2122也可以用于进水，而第一接头321和第一凹槽2121用于出水，且此时第一凹槽2121连通出水管23第二凹槽2122连通进水管22，由此，不仅能够提升水流通道的密闭性，还能防止进水水流和出水水流之间发生串水。
进一步地，如图6所示，第二接头322的外周面设有沿其周向延伸的密封卡环323，密封卡环323可以设置一个，也可以设置多个，当滤芯接头32插接 在安装槽212内时，密封卡环323的外周缘与第二凹槽2122的内壁密封配合，防止水流通过第二接头322与第二凹槽2122之间的间隙泄露，进一步提升了滤芯组件100的密封性。
