本发明提出一种净水***，请参照图1，图示出了本发明的净水***的结构示意图。该净水***100包括膜滤芯10、增压泵15、电磁阀20、废水阀25、阻垢装置30、废水回流阀35、控制器（未图示）以及其他部件。
该膜滤芯10具有原水口a、纯水口b以及废水口c；膜滤芯10的原水口a与原水管连接，外部的原水通过原水管流入膜滤芯10内；膜滤芯10的纯水口b与纯水管连接，经膜滤芯10过滤产生的纯水通过纯水管排出；膜滤芯10的废水口c与废水管连通，经膜滤芯10过滤产生的废水通过废水管排出，该废水管的出水端还可以与废水箱连通，这样就便于废水的收集，并且收集于废水箱中的废水还可以用作它用，这样就避免了水资源的浪费。
增压泵15安装于原水管上，其主要用于给原水管内的原水加压，这样就使得从原水口a流入膜滤芯10内的水压足够高，进而有利于提高膜滤芯10制取纯水的速度。
电磁阀20安装于废水管上，其用于控制废水管的通断。
废水阀25安装于废水管上并位于电磁阀20的出水侧，该废水阀25可以是开度可以调节的阀，也可以是开度固定的阀，在此不做具体的限定。
阻垢装置30安装于废水管上并位于电磁阀20和废水阀25之间，该阻垢装置30内设置有阻垢剂，该阻垢剂可以是硅磷晶、SP3等等，其能与水中钙离子、镁离子形成可溶性络合物，进而能够有效阻止钙离子、镁离子于废水阀25以及废水管内形成水垢，进而确保了废水管和废水阀25不会被结块杂质所堵塞。
废水回流阀35的进水端连接至位于电磁阀20与阻垢装置30之间的废水管上，废水回流阀35的出水端连接至所述原水管上。如此设置，一方面使得由膜滤芯10过滤产生的一部分废水能够回流至膜滤芯10内并得到过滤，这样就有利于提高水的利用率；另一方面，还能够保证膜滤芯10的膜前水压不会过高，这样就有利于延长膜滤芯10的使用寿命。
需要说明的是，阻垢剂对人体有害，将废水回流阀35的进水端设置于阻垢装置30的进水侧，这样就能确保通过废水回流阀35回流至膜滤芯10内的废水未携带阻垢剂，从而确保了净水***100制取的纯水中离子不会出现超标，进而确保了膜滤芯10过滤产生的纯水的安全性。
控制器与增压泵15、废水阀25、废水回流阀35以及电磁阀20均电性连接，其用于控制增压泵15、废水阀25、废水回流阀35以及电磁阀20的工作，即控制增压泵15、废水阀25、废水回流阀35以及电磁阀20的开启或关闭，该控制器可以是单片机，也可以是PWM控制器，在此对控制器不做具体的限定。
当净水***100制取纯水时，请参照图1，控制器控制增压泵15、废水回流阀35、电磁阀20、废水阀25均开启，原水管中的低压原水通过增压泵15增压后形成高压原水，并且原水管内的高压原水通过膜滤芯10的原水口a进入膜滤芯10内，进入膜滤芯10内的原水经膜滤芯10过滤后形成纯水和废水，纯水从膜滤芯10的纯水口b排出，以供用户取用；废水则从膜滤芯10的废水口c排入废水管中，并通过废水管排出；而进入废水管中的一部分废水直接通过废水管排至外界，另一部分废水流经废水回流阀35后流入原水管中，并与原水管中的原水混合后一同流入膜滤芯10中进行过滤，这样就减少了净水***100的废水排出量，也即提高了净水***100的产水率。
当废水回流阀35满足预设冲洗条件时，请参照图2，控制器控制增压泵15和电磁阀20关闭，也即关闭膜滤芯10的进水口和废水口c，这样就使得原水无法进入膜滤芯10内，膜滤芯10的废水口c也不排废水，原水管中的原水直接从废水回流阀35的出水端流向废水回流阀35的进水端。由于原水中钙离子、镁离子等杂质的浓度要远远低于废水中钙离子、镁离子等杂质的浓度，当原水流经废水回流阀35时，能够将附着于废水回流阀25所在的管路以及废水回流阀35上的钙离子、镁离子等杂质冲洗掉，这样就避免了钙离子、镁离子等杂质在废水回流阀25所在的管路以及废水回流阀35处堆积而结块，进而导致废水回流阀25所在的管路以及废水回流阀35被结块的杂质所堵塞的问题发生。
需要说明的是，上述废水回流阀35的预设冲洗条件可以是废水回流阀35的工作时长、可以是通过废水回流阀35的累计流量等等，在此就不一一列举，只要满足预设冲洗条件，控制器就控制增压泵15和电磁阀20关闭，以对废水回流阀35进行冲洗。
本发明通过将增压泵15设置于与膜滤芯10的原水口连通的原水管上，电磁阀20安装于废水管上，废水阀25安装于废水管上并位于电磁阀20的出水侧，阻垢装置30安装于废水管上并位于电磁阀20和废水阀25之间，废水回流阀35的进水端连接至位于电磁阀20与阻垢装置30之间的废水管上，废水回流阀35的出水端连接至原水管上，净水***100的控制器分别与增压泵15、电磁阀20以及废水阀25电性连接，并且控制器在废水回流阀35满足预设冲洗条件时，控制增压泵15和电磁阀20关闭，并控制废水阀25打开，以使得原水管内的原水对废水回流阀35进行冲洗。由于原水所含的钙离子、镁离子等杂质的浓度要低于废水中钙离子、镁离子等杂质的浓度，原水在流经废水回流阀35时，能够将附着于废水回流阀35上的钙离子、镁离子等杂质冲洗掉，这样就避免了废水中的钙离子、镁离子等杂质在废水回流阀35以及废水回流阀35所在的管路上结垢，进而确保了废水回流阀35以及废水回流阀35所在的管路被堵塞的问题发生；另外，设置于废水管上的阻垢装置30能够将通过废水管排至外界的废水中的钙离子、镁离子等离子去除，这样就避免了废水中的钙离子、镁离子等离子在废水阀25以及废水管上而形成水垢，进而避免了废水阀25以及废水管被堵塞的问题发生。
在本发明的一实施例中，请参照图3，该净水***100还包括与控制器电性连接的流量计40，该流量计40安装于废水回流阀35上或者该流量计40安装于废水回流阀35的进水端或出水端，在此不做具体的限定。该流量计40用于检测通过废水回流阀35的流量值，并且该流量计40将检测结果实时反馈给控制器；控制器根据流量计40反馈的检测结果控制增压泵15和电磁阀20的开关。
具体的，在流量计40检测到通过废水回流阀35的流量值达到预设流量值时，控制器控制增压泵15和电磁阀20关闭，此时原水管内的原水从废水回流阀35的出水端流向废水回流阀35的进水端，以对废水回流阀35进行冲洗，这样就使得附着于废水回流阀35上的钙离子、镁离子等杂质被原水冲洗掉，从而避免了附着于废水回流阀35上的杂质结块而将废水回流阀35堵塞的问题发生。
并且，控制器在增压泵15和电磁阀20关闭第一定时时长后，控制增压泵15和电磁阀20均开启，也即将净水***100切换至制取纯水模式。整个净水***100在制取纯水和冲洗废水回流阀35时均不需要用户操作，即净水***100可以在制取纯水和冲洗废水回流阀35两种模式下智能切换。如此设置，一方面简化了净水***100的操作，即用户只需为净水***100上电即可，进而有利于提高用户的体验；另一方面，净水***100智能冲洗废水回流阀35，确保了废水回流阀35不会被堵塞，延长了废水回流阀35的使用寿命，进而避免了净水***100需要频繁更换废水回流阀35。
需要说明的是，上述控制器在流量计40检测到通过废水回流阀35的流量值达预设流量值后，会将流量计40的数值进行清零处理。
应当说的是，上述控制器在增压泵15和电磁阀20关闭第一定时时长，也即废水回流阀35的冲洗时长可以采用本领域技术人员公知的定时电路或者定时器来实现，由于定时电路和定时器是本领域技术人员公知的技术，在此就不再赘述。
另外，若上述净水***100用在水质较好的地区，则预设流量值的数值可以设置的相对大一些，这样就避免了净水***100频繁冲洗废水回流阀35的情况出现；若上述净水***100用在水质较差的地区，则预设流量值的数值可以设置的相对较小一些，这样就能够避免废水回流阀35被结块的杂质所封堵。
在本发明的一实施例中，该净水***100还包括与控制器电性连接的计时器（未图示），该计时器用于检测废水回流阀35的工作时长，并将检测结果发送给控制器，控制器根据计时器发送的结果控制增压泵15和电磁阀20的开关。
具体的，在计时器检测到废水回流阀35的工作时长达到预设工作时长时，控制器控制增压泵15和电磁阀20均关闭，此时原水管内的原水从废水回流阀35的出水端流向废水回流阀35的进水端，以对废水回流阀35进行冲洗，附着于废水回流阀35上的杂质会被原水冲洗掉，这样就避免了废水回流阀35堵塞。
并且，控制器控制增压泵15和电磁阀20关闭第二定时时长后，控制增压泵15和电磁阀20均开启，也即将净水***100切换至制取纯水模式。整个净水***100在制取纯水和冲洗废水回流阀35时均不需要用户操作，即净水***100可以在制取纯水和冲洗废水回流阀35两种模式下智能切换。如此设置，一方面简化了净水***100的操作，即用户只需为净水***100上电即可，进而有利于提高用户的体验；另一方面，净水***100智能冲洗废水回流阀35，确保了废水回流阀35不会被堵塞，延长了废水回流阀35的使用寿命，进而避免了净水***100需要频繁更换废水回流阀35。
需要说明的是，上述控制器在计时器检测到废水回流阀35的工作时长达到预设工作时长时，会将计时器的计数进行清零处理。
应当说的是，上述控制器在增压泵15和电磁阀20关闭第二定时时长，也即废水回流阀35的冲洗时长可以采用本领域技术人员公知的定时电路或者定时器来实现，由于定时电路和定时器是本领域技术人员公知的技术，在此就不再赘述。
另外，需要说明的是，若上述净水***100用在水质较好的地区，则废水回流阀35的预设工作时长可以设置的相对长一点，这样就避免了净水***100频繁冲洗废水回流阀35的情况出现；若上述净水***100用在水质较差的地区，则废水回流阀35的预设工作时长可以设置的相对短一点，这样就能够避免废水回流阀35被结块的杂质所封堵。
在本发明的一实施例中，请参照图4，该净水***100还包括与控制器电性连接的第一TDS检测装置45，该第一TDS检测装置45安装于废水回流阀35上或者该第一TDS检测装置45安装于废水回流阀35的进水端或出水端，第一TDS检测装置45用于检测流经废水回流阀35的废水的TDS值，并将检测结果发送至控制器；控制器根据第一TDS检测装置45发送的检测结果控制增压泵15和电磁阀20的开关。
具体的，废水管中的废水回流至原水管中并与原水管的原水混合后一起流入膜滤芯10中进行过滤，过滤后形成的废水又会有一部分回流至原水管中与原水混合，如此循环，就会使得从废水管中排出的废水的TDS值升高。当第一TDS检测装置45检测到流经废水回流阀35的废水的TDS值达到第一预设TDS值时，控制器控制增压泵15和电磁阀20关闭，此时原水管内的原水从废水回流阀35的出水端流向废水回流阀35的进水端，以对废水回流阀35进行冲洗，原水与回流至原水管的废水相比较，原水中所含的杂质更少，这样就使得附着于废水回流阀35上的杂质会被原水冲洗掉，从而避免了废水回流阀35发生堵塞。
并且，控制器在增压泵15和电磁阀20关闭第三定时时长后，控制增压泵15和电磁阀20均开启，也即将净水***100切换至制取纯水模式。整个净水***100在制取纯水和冲洗废水回流阀35时均不需要用户操作，即净水***100可以在制取纯水和冲洗废水回流阀35两种模式下智能切换。如此设置，一方面简化了净水***100的操作，即用户只需为净水***100上电即可，进而有利于提高用户的体验；另一方面，净水***100智能冲洗废水回流阀35，确保了废水回流阀35不会被堵塞，延长了废水回流阀35的使用寿命，进而避免了净水***100需要频繁更换废水回流阀35。
应当说的是，上述控制器在增压泵15和电磁阀20关闭第三定时时长，也即废水回流阀35的冲洗时长可以采用本领域技术人员公知的定时电路或者定时器来实现，由于定时电路和定时器是本领域技术人员公知的技术，在此就不再赘述。
进一步地，上述控制器将第一TDS检测装置45在第三定时时长内发送的检测结果的平均值与第一预设TDS值比较，并根据比较的结果控制增压泵15和电磁阀20工作。如此设置，避免了净水***100用在水质较差的地区时，净水***100一直处于冲洗废水回流阀35的问题出现。
需要说明的是，若上述净水***100用在水质较好的地区，则第一TDS检测装置45检测的预设时间段可以设置的相对长一些，这样就避免了净水***100频繁冲洗废水回流阀35的情况出现；若上述净水***100用在水质较差的地区，则第一TDS检测装置45检测的预设时间段可以设置的相对短一些，这样就能够避免废水回流阀35被结块的杂质所封堵。
在本发明的一实施例中，请参照图5，该净水***100还包括串接至废水回流阀35的进水端或出水端的双向水泵50，该双向水泵50与控制器电性连接，控制器根据净水***100的工作模式控制双向水泵50工作。
具体的，在净水***100制取纯水时，控制器控制增压泵15和电磁阀20均开启，并控制双向水泵50正转，由于双向水泵50的存在，使得自废水管回流至原水管中的废水的流速提高，这样就使得更多的废水回流至膜滤芯10内，进而提高了水的利用率。在废水回流阀35满足预设冲洗条件时，控制器控制增压泵15和电磁阀20关闭的同时，还控制双向水泵50反转，从废水回流阀35的出水端流向废水回流阀35的进水端的原水在双向水泵50的加压下，其流速和水压都得到提高，这样就确保了附着于废水回流阀35上的杂质能够被冲洗掉，进而避免了废水回流阀35被结块的杂质所堵塞的问题出现。
在本发明的一实施例中，请参照图6，该净水***100还包括第一单向阀55，该第一单向阀55串接至阻垢装置30与电磁阀20之间的管路上，而废水回流阀35的进水端连接至位于第一单向阀55和电磁阀20之间的管路上。第一单向阀55的设置，使得进入第一单向阀55与阻垢装置30之间的废水管中的废水只能从废水管的出水端排出，也就是说，即使阻垢装置30内的阻垢剂溶解于废水中，含有阻垢剂的废水也无法通过第一单向阀55而回流至膜滤芯10内，这也就确保了通过废水回流阀35回流至膜滤芯10内的废水中不含阻垢剂，这样就保证了膜滤芯10制取的纯水的离子浓度不会出现超标。
在本发明的一实施例中，请参照图7，该废水阀25的开度是可调节的，其用于调节通过废水管排至外界的废水的流量大小。为了方便控制废水阀25的开度，该净水***100还包括与控制器电性连接的第二TDS检测装置60，第二TDS检测装置60安装于废水阀25上或者安装于废水管上，其用于检测通过废水管排至外界的废水TDS值，控制器根据第二TDS检测装置60的检测结果控制废水阀25工作。
具体的，在第二TDS检测装置60检测的废水TDS值小于或等于第二预设TDS值时，控制器控制废水阀25的开度减小或保持不变，这样就减少或保持了膜滤芯10的废水排出量，也即使得膜滤芯10过滤产生的废水大部分通过废水回流阀35所在的管路回流至膜滤芯10内，从而提高了水的利用率，也提高了净水***100的产水率。在第二TDS检测装置60检测到通过废水管的废水TDS值要大于第二预设TDS值时，控制器控制废水阀25的开度增大，这样就增大了废水管排水量，也即增大了膜滤芯10的废水排出速度和排出量，从而使得膜滤芯10中的废水能够及时排出。并且当废水阀25处于全开状态时，膜滤芯10的废水排出速度为最大，由于膜滤芯10的废水排出速度较快，存留于膜滤芯10内的杂质容易被冲洗出来，这样就有利于延长膜滤芯10的使用寿命。
进一步地，上述废水阀25的规格小于或等于800cc/min。采用规格小于800cc/min的废水阀25，能够减少净水***100的废水排出量，以确保废水阀25即使处于全开状态时，膜滤芯10的纯水排出量与膜滤芯10的废水排出量的比例保持为3比1或者大于3比1，这样就大大地提高了净水***100的产水率，减少了废水的产生。
在本发明的一实施例中，请参照图1至图7任意一附图，该净水***100还包括与控制器电性连接的进水阀65，并且该进水阀65安装于位于增压泵15进水侧的原水管上。当净水***100停止工作时，控制器控制增压泵15和进水阀65均关闭，由于进水阀65是位于增压泵15的进水侧，这样就保证了位于增压泵15和进水阀65之间的原水管中存留有原水，从而避免了净水***100启动工作时，增压泵15出现空转的情况出现，进而有效地保护了增压泵15。
在本发明的一实施例中，请参照图1至图7任意一附图，该净水***100还包括前置滤芯70，该前置滤芯70的进水口与水源连通，该净水***100的出水口与原水管的进水端连通。该前置滤芯70可以是PP棉滤芯、活性炭滤芯或者其他具有纯水功能的滤芯，在此不做具体的限定。在原水管前设置前置滤芯70，这样就能够有效的过滤掉原水中大颗粒杂质，进而避免了原水中颗粒杂质附着于膜滤芯10内和废水回流阀35上，进而导致膜元件和废水回流阀35被堵塞的问题发生。
优选地，上述前置滤芯70为PAC复合滤芯，该PAC复合滤芯包括无纺布、碳纤维和PP棉三层复合形成，即PAC复合滤芯集合了碳纤维滤芯和PP棉滤芯的功能，也即用一个滤芯可以代替两个滤芯，这样就减少了前置滤芯70的数量，进而使得整个净水***100所需要的安装空间更小。
在本发明的一实施例中，请参照图1至图7任意一附图，该净水***100还包括后置滤芯75，该后置滤芯75的进水口与纯水管的出水端连接，该后置滤芯75的出水口与外部接水口连通。该后置滤芯75可以是活性炭滤芯，活性炭滤芯主要以活性炭为主要原料，其能够去除水中的余氯、异味等，同时还能改善水的口感，进而有利于提升用户的体验。
进一步地，该净水***100还包括与控制器电性连接的第二单向阀80，该第二单向阀80安装于与后置滤芯75的出水口连通的外部水管上，这样就避免了从后置滤芯75流出的水回流至后置滤芯75内。
在本发明的一实施例中，请参照图1至图7任意一附图，该净水***100还包括UV杀菌水龙头85，其安装于纯水管的出水端。当用户需要取用纯水时，可打开UV杀菌水龙头85，膜滤芯10内的纯水流经UV杀菌水龙头85时，UV杀菌水龙头85能够对纯水进行有效地杀菌，这样就使得纯水中的细菌均被杀死，进而确保了用户取到的纯水是干净、安全的。
在本发明的一实施例中，请参照图1至图7任意一附图，该净水***100还包括安装于纯水管上的压力检测装置90，该压力检测装置90用于检测纯水管内的压力大小；控制器与压力检测装置90电性连接，并根据压力检测装置90发送的检测结果控制净水***100的启动或关闭。
具体的，该压力检测装置90为压力开关，当纯水管的出水端打开时，由于纯水向出水端流动，这样就使得压力开关处的压力降低，即压力开关检测的压力值要低于预设压力值，此时控制器控制增压泵15、废水回流阀35、电磁阀20以及废水回流阀25同时打开，也即启动净水***100制取纯水。当纯水管的出水端关闭时，此时膜滤芯10内的纯水会持续向纯水管的出水端流，直至充满整个纯水管，这样就使得纯水管内的压力增大，也就是说，此时压力开关检测到的压力值等于或大于预设压力值，控制器控制增压泵15、废水回流阀35、电磁阀20以及废水回流阀25同时关闭。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是在本发明的发明构思下，利用本发明说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本发明的专利保护范围内。
