如图1-图4所示,根据本发明实施例的净水系统100,包括:复合滤芯组件1、增压泵4、废水电磁阀7和蓄水装置。
具体而言,复合滤芯组件1包括滤壳11和设在滤壳11内的复合滤芯12,滤壳11具有原水进口111、纯水口114、纯水出口112和浓缩水出口113,复合滤芯12包括过滤组件和设在过滤组件下游的口感滤芯123,纯水口114与过滤组件的出水端连通且与口感滤芯123的进水端连通。由此,通过将口感滤芯123与过滤组件复合成一体化滤 芯,进一步地有利于整机尺寸的小型化,减少接头数量及漏水风险。在更换滤芯时,一次只需要整体更换一支滤芯,减少用户的更换频次,方便了用户的使用。
增压泵4与原水进口111相连,增压泵4用于提高进水压力。废水电磁阀7与浓缩水出口113相连,废水电磁阀7用于调节废水比例,以平衡净水系统100的工作压力。蓄水装置与纯水口114相连,蓄水装置用于储存从纯水口114流出的纯水。由此,通过设置的蓄水装置,可以将纯水储存在蓄水装置中,由此在水压不足时依然可以满足用户的大通量需求。
下面参照图1-图4简要说明净水系统100的工作过程。
参照图1-图4,原水经增压泵4增压后从滤壳11上的原水进口111进入滤壳11内,并通过过滤组件进行过滤。经过滤组件过滤后形成的纯水通过滤壳11上的纯水口114流出并流入蓄水装置内,蓄水装置储存该纯水以待饮用。而产生的浓缩水经滤壳11上的浓缩水出口113排出净水系统100。
在需要饮水时,蓄水装置内储存的纯水可以通过纯水口114回到滤壳11内并进入口感滤芯123的进水端,同时从原水进口111进入的原水可以依次通过过滤组件过滤后进入口感滤芯123的进水端。进入口感滤芯123的进水端的纯水通过口感滤芯123过滤并改善口感后,通过滤壳11上的纯水出口112流出以饮用。由此,可以增大水通量和单位时间的出水量,在水压不足时依然可以满足用户的大通量需求。并且,通过将蓄水装置设置在口感滤芯123的上游,可以去除蓄水装置中的纯水存放时间久了所产生的异味,保证净水系统100最终的出水品质。
根据本发明实施例的净水系统100,通过将口感滤芯123与过滤组件复合成一体化滤芯,进一步地有利于整机尺寸的小型化,减少接头数量及漏水风险,并且通过设置的蓄水装置,可以将纯水储存在蓄水装置中,由此在水压不足时依然可以满足用户的大通量需求。
根据本发明的一些实施例,参照图1,所述蓄水装置包括:用于储存纯水的蓄水容器91、低压开关93和水泵92。低压开关93连接在蓄水容器91与纯水口114之间,低压开关93通过检测管路中的水压以判断蓄水容器91内的纯水是否已满。在蓄水容器91内的纯水已满时,管路中的水压较大,此时低压开关93断开,防止蓄水容器91内压力过大而产生漏水、损坏等问题,提高净水系统100的可靠性;在蓄水容器91内的水位较低时,管路中的水压较低,低压开关93闭合。水泵92连接在蓄水容器91与纯水口114之间,水泵92用于将蓄水容器91内的纯水输送至纯水口114。由此,通过水泵92将蓄水容器91内的纯水输送至纯水口114,增大净化系统的出水量,同时通过设置的低压开关93,可以提高净水系统100的可靠性。可选地,蓄水容器91可以为水 袋或压力罐等出水设备。
进一步地,参照图1,蓄水装置还包括:进水电磁阀94,进水电磁阀94的一端与纯水口114相连且另一端与低压开关93相连。由此,通过设置的进水电磁阀94与低压开关93的配合使用,既可以方便地控制水路的通断,同时可以提高净水系统100的可靠性。
根据本发明的一些实施例,参照图3,过滤组件与口感滤芯123沿上下方向排布。由此,可以实现复合滤芯12在上下方向上的立体排布,减小复合滤芯12的直径,有利于减小整机的尺寸。例如,口感滤芯123可以位于过滤组件的上方,使得整个复合滤芯12的结构合理、稳定,同时方便复合滤芯12内部的流路设计。
根据本发明的一些实施例,参照图3和图4,过滤组件包括由外向内依次设置的预处理滤芯121和精细过滤滤芯122,精细过滤滤芯122包括中心集水管1221和卷绕在中心集水管1221上的精细过滤膜1222,原水进口111与预处理滤芯121的进水端连通,中心集水管1221构成过滤组件的出水端。其中,预处理滤芯121可以为PAC(PP And C,PP棉和活性炭复合滤芯12)预处理滤芯121,例如预处理滤芯121可以包括沿复合滤芯12的径向由外至内依次分布的PP无纺布卷绕层(PP无纺布卷绕层的精度可以设置为5um)和活性炭纤维卷绕层,预处理滤芯121可以有效去除铁锈、泥沙、吸附水中的异色、异味、余氯及部分有机物,确保进入精细过滤滤芯122的水质,延长精细过滤滤芯122的寿命。精细过滤滤芯122的精细过滤膜1222可以为反渗透膜或纳滤膜,精细过滤滤芯122可以拦截细菌病毒、重金属等,精细过滤滤芯122可以采用多膜页卷制技术制成,由此可以提高精细过滤滤芯122的性能。
复合滤芯12还包括:第一端盖124和第二端盖125,第一端盖124设在过滤组件的轴向一端(例如,参照图3中的第一端盖124设在过滤组件的下端)且与过滤组件相连以封盖过滤组件的轴向一端。例如,在图3的示例中,第一端盖124可以形成为圆盘形,第一端盖124的周沿形成有向上延伸的第一翻边部1241以及位于第一翻边部1241的内侧且在第一端盖124的径向方向上间隔开设置的第二翻边部1242,第一翻边部1241和第二翻边部1242之间形成环形的第一容纳腔1243,预处理滤芯121的下端容纳在上述第一容纳腔1243内且与第一翻边部1241的内侧壁和第二翻边部1242的外侧壁紧密配合。第一端盖124的上还形成朝向精细过滤滤芯122延伸的安装凸台1244,安装凸台1244配合在精细过滤滤芯122的中心集水管1221内,从而可以使第一端盖124与过滤组件稳定、可靠地连接。
第二端盖125呈筒形,第二端盖125设在过滤组件的轴向另一端(例如,参照图3中的第二端盖125设在过滤组件的上端)且与预处理滤芯121相连。例如,在图3的 示例中,第二端盖125的下端的外周沿和内周沿上分别形成有向下延伸的第三翻边部1251、第四翻边部1252,第三翻边部1251和第四翻边部1252之间形成环形的第二容纳腔1253,预处理滤芯121的上端容纳在上述第二容纳腔1253内且与第三翻边部1251的内侧壁和第四翻边部1252的外侧壁紧密配合,从而可以使第二端盖125与预处理滤芯121稳定、可靠地连接。
口感滤芯123设在第二端盖125内,口感滤芯123与中心集水管1221相连且位于精细过滤滤芯122的下游,口感滤芯123可以为活性炭层,例如口感滤芯123可以为活性炭棒,口感滤芯123可以去除挥发性有机物、残余余氯,并可以保留必须的矿物质如微量钙、硅酸、碳酸根等,可以使口感甘甜、柔和。口感滤芯123与第二端盖125之间限定出由外向内依次设置且相互间隔开的浓缩水通道a1和流通通道a2,浓缩水出口113与浓缩水通道a1连通,流通通道a2构成口感滤芯123的进水端且流通通道a2连通纯水口114和中心集水管1221,口感滤芯123上设有适于纯水流出的纯水通道a3,纯水通道a3与纯水出口112连通。
由此,通过将预处理滤芯121和精细过滤滤芯122由外向内依次设置,并将位于精细过滤滤芯122下游的口感滤芯123设置在精细过滤滤芯122的轴向端,由此使得复合滤芯12整体设置成立体排布,从而可以减小复合滤芯12的直径,对滤壳11耐压有利,结构简单、体积小,有利于整机的小型化,并且出水的品质好。
下面参照图1-图4简要说明上述复合滤芯12的过滤过程。
参照图3(图中的箭头方向为水流方向)并结合图1、图2和图4,,原水先通过预处理滤芯121进行初步过滤,而后通过精细过滤滤芯122进行精细过滤,经精细过滤滤芯122过滤的水分成两部分:其中一部分为纯水,纯水通过精细过滤滤芯122的中心集水管1221进行收集,中心集水管1221内的纯水流入上述流通通道a2,并通过滤壳11上的纯水口114流入蓄水装置内进行储存;另一部分为浓缩水,浓缩水经浓缩水通道a1及滤壳11上的浓缩水出口113流出并通过废水电磁阀7排出净水系统100。
在需要饮水时,蓄水装置内储存的纯水可以通过纯水口114回到滤壳11内并进入上述流通通道a2内,同时从原水进口111进入的原水可以依次通过过滤组件的预处理滤芯121及精细过滤滤芯122进行过滤,其中纯水经中心集水管1221流入上述流通通道a2内。进入流通通道a2内的纯水通过口感滤芯123过滤并改善口感后流入口感滤芯123上的纯水通道a3,而后通过滤壳11上的纯水出口112流出以饮用。
根据本发明进一步的实施例,参照图3和图4,净水系统100还包括:连接壳126,连接壳126设在第二端盖125内且与中心集水管1221相连,连接壳126与第二端盖125之间限定出浓缩水通道a1,口感滤芯123设在连接壳126内,口感滤芯123与连接壳 126的内壁之间限定出流通通道a2。由此,通过设置的连接壳126,方便了口感滤芯123的装配,并且可以方便地将口感滤芯123与过滤组件隔开。
可选地,参照图4,连接壳126的内壁与口感滤芯123之间设有凸块1261以使连接壳126的内壁与口感滤芯123间隔开,连接壳126的内壁与口感滤芯123之间的间隙构成流通通道a2。由此,通过设置的凸块1261,使得连接壳126的内壁与口感滤芯123间隔开,以便于在口感滤芯123与连接壳126的内壁之间形成上述的流通通道a2,从而使得从精细过滤滤芯122的中心集水管1221内出来的水顺利流入口感滤芯123进行过滤。可选地,上述凸块1261可以形成在连接壳126的内壁上,凸块1261可以为一个且形成为环形,凸块1261也可以杆状且可以包括间隔分布的多个。
可选地,参照图3和图4,连接壳126上形成有环形凸起1262,中心集水管1221的出水端(参照图3和图4中的中心集水管1221的上端)配合在环形凸起1262内。由此,通过中心集水管1221配合在连接壳126的环形凸起1262内,方便了口感滤芯123与精细过滤滤芯122的连接,且连接快捷、可靠,并且使得中心集水管1221内的纯水顺利流入连接壳126内。
进一步地,参照图4,上述环形凸起1262的内周壁与中心集水管1221的外周壁之间可以设置密封件1264(例如密封圈),由此可以保证连接壳126与中心集水管1221之间连接的密封性,防止浓缩水通道a1内的浓缩水进入连接壳126内。
可选地,净水系统100还包括:第一定位件127和第二定位件128,第一定位件127和第二定位件128分别设在口感滤芯123的轴向两端且与口感滤芯123相连。由此,通过设置的第一定位件127和第二定位件128,可以对口感滤芯123在轴向(参照图3中的上下方向)上进行限位,从而可以方便地将口感滤芯123定位在连接壳126内,使得复合滤芯12的结构稳定可靠。
进一步地,参照图3和图4,口感滤芯123呈管状,口感滤芯123的轴向两端均可以敞开,由此使得口感滤芯123的结构简单、易于加工成型,口感滤芯123的内孔构成纯水通道a3,从而无需另外在口感滤芯123上设置纯水通道a3。第一定位件127包括第一定位本体1271和形成在第一定位本体1271上的第一限位凸起1273,第一定位本体1271封盖口感滤芯123的邻近中心集水管1221的一端(参照图3中口感滤芯123的下端),以使口感滤芯123内的纯水通道a3与中心集水管1221隔开,防止中心集水管1221内的水未经过口感滤芯123而直接进入纯水通道a3内,第一限位凸起1273配合在口感滤芯123的内孔内。
第二定位件128包括第二定位本体1281和形成在第二定位本体1281上的第二限位凸起1283,第二定位本体1281设在口感滤芯123的远离中心集水管1221的一端(参 照图3中口感滤芯123的上端),第二限位凸起1283配合在口感滤芯123的内孔内且第二限位凸起1283上形成有沿轴向贯通第二定位件128的通水孔1284,由此纯水通道a3内的纯水可以通过第二定位件128上的通水孔1284流出以供饮用。
由此,通过将口感滤芯123设置呈管状,方便口感滤芯123上的纯水通道a3的形成,并且通过第一定位件127上的第一限位凸起1273和第二定位件128上的第二限位凸起1283分别与口感滤芯123的内孔的配合,使得口感滤芯123的安装、定位更加方便、快捷,且使得复合滤芯12内的流道结构简单。

第一定位本体1271呈圆形,第一定位本体1271的周沿形成有向上延伸的第五翻边部1272,口感滤芯123的下端与第五翻边部1272的内周壁止抵,从而可以进一步地增加第一定位件127与口感滤芯123配合的稳定性,第五翻边部1272第五翻边部1272与连接壳126的内周壁间隔开,此时第一定位件127与连接壳126的内壁之间的间隙及口感滤芯123的外周壁与连接壳126的内壁之间的间隙共同构成上述流通通道a2。第二定位本体1281呈圆形,第二定位本体1281的周沿形成有向下延伸的第六翻边部 1282,口感滤芯123的上端与第六翻边部1282的内周壁止抵,从而可以进一步地增加第二定位件128与口感滤芯123配合的稳定性。
进水管路b1与滤壳11的原水进口111相连,在水流方向上前置过滤网2、进水电磁阀94及增压泵4依次串接在进水管路b1上,前置过滤网2用于过滤原水中尺寸较大的铁锈、泥沙等,原水进水电磁阀3用于控制原水进水管路b1的通断。蓄水管路b4的两端均与纯水口114相连,进水电磁阀94、低压开关93、蓄水容器91及水泵92依次串接在蓄水管路b4上。纯水管路b2与滤壳11上的纯水出口112相连,在水流方向上单向阀5、高压开关6和水龙头8依次串接在纯水管路b2上,单向阀5在从纯水出口112至水龙头8的方向上单向导通,单向阀5用于防止纯水管路b2内的水倒流至复合滤芯12内,高压开关6可以根据纯水管路b2内水压检测水龙头8是处于打开状态还是关闭状态。
