Description

一种基于滤芯识别防伪的水净化装置
技术领域
本发明涉及水过滤器，尤其是一种基于滤芯识别防伪的水净化装置。
背景技术
日常自来水虽已做过过滤、澄清、消毒等处理，符合国家生活饮用水卫生标准，但在输送过程中由于管道锈迹或管外渗入容易造成二次污染，导致水中含过量细菌、病毒、余氯、有机物、重金属、放射性物质等各类有害物质，净水器正是将这些对人体有害的物质过滤掉。
近年来饮用水卫生越来越受到人们的重视，水净化器也被广泛应用于家居生活，各类净水机都是依靠滤芯来实现净水作用，在某种程度上讲，滤芯是净水器的“灵魂”，水净化器的滤芯需要定期更换，才能保持良好的过滤效果。目前市场上净水器的销售量持续高涨，但出现大量的滤芯仿冒产品，滤芯用料质量得不到保障，过滤性能远低于原装的滤芯，使用此类仿冒的滤芯并不能达到水净化的效果，达不到饮用水标准，且使用寿命低，有损消费者的利益，对整机厂的声誉也造成不良影响。
发明内容
为了解决现有仿冒滤芯产品泛滥的问题，本发明提供的一种基于滤芯识别防伪的水净化装置，只有原厂的滤芯通过身份识别配对成功后，该水净化装置才能正常工作，有效保证过滤水质量。
为了实现上述目的，本发明所采用的技术方案是：
一种基于滤芯识别防伪的水净化装置，包括滤芯组件、增压泵和滤膜组件，所述滤芯组件的进水口和出水口分别连接供水管和增压泵，所述增压泵的出水口与滤膜组件的进水口连接，所述滤膜组件上设有净水出水口和废水出水口，所述滤芯组件和滤膜组件上设置有身份识别芯片与安装在水净化装置上的身份识别器进行配对，所述身份识别芯片分别安装位于滤芯组件和滤膜组件的滤芯上，所述增压泵通过与身份识别器连接，当且仅当各身份识别芯片同时与身份识别器配对成功后，所述身份识别器才输出控制信号驱动增压泵工作。上述的身份识别芯片与身份识别器作为身份识别单元，独立运行对过滤芯进行识别配对，只有安装有身份识别芯片的原厂滤芯才能与水净化装置匹配使用，实现滤芯防伪功能。
上述结构中，所述身份识别芯片与身份识别器分别为电子标签与读取器，所述电子标签由非接触式IC以及围绕所述非接触式IC设置的射频天线构成，所述读取器通过无线射频识别非接触式IC进行数据交换。采用非接触式的自动识别技术，当滤芯安装进滤芯组件内时会自动进入识别工作，由读取器通过内置的天线发出射频信号，电子标签通过射频天线接收到读取器发出的读取指令后，返回射频信号进行响应，把产品的信息传递给读取器，并进行密码校验配对，从而实现自动身份识别功能。
优选的，所述非接触式IC为射频识别芯片，其工作频率为840 ～ 960MH，该非接触式IC内设有数据储存器和记时器。所述数据储存器内的数据可随时更新、可读写，记录包括产品的厂家信息、生产日期、校验密码等数据，所述记时器能够实时记录滤芯的累计工作时间，当到达滤芯的使用寿命时间时，所述非接触式IC对水净化器发出停止的指令，即非接触式IC会发出控制信号中断增压泵的工作，同时发送信号提醒更换滤芯。
优选的，所述射频天线是印刷天线、刻蚀天线，或绕制天线，根据不同材质的滤芯使用不同材质的射频天线，保证射频信号传输的稳定性。
优选的，所述射频天线以圆形、三角形、方形、椭圆形或不规则型任意形式环绕非接触式IC。
上述的射频天线的线宽范围为0.5-50mm。
优选的，所述滤芯组件包括有最少两个滤芯，所述滤膜组件包括有最少一个滤膜滤芯，每个滤芯和滤膜滤芯上各设置有电子标签且滤芯和滤膜滤芯上的身份识别芯片都与身份识别器全部配对成功后，所述身份识别器才输出控制信号驱动增压泵工作，可以对滤芯组件和滤膜组件都起到防伪保护作用。
更优选的，所述滤芯组件最少包括一个PP棉滤芯和一个活性炭滤芯，自来水经过PP棉滤芯进行粗过滤，通过活性炭滤芯进行吸附过滤，可以设置多级滤芯进行过滤，提高过滤效果。
优选的，所述读取模块在50m距离之内同时读取多个滤芯上的电子标签。
优选的，所述增压泵与滤芯组件之间设有进水电磁阀和低压开关，所述低压开关连接在进水电磁阀的进水端，所述进水电磁阀的出水端连接增压泵。通过进水电磁阀进行进水控制，所述低压开关主要是用于保护增压泵，当水压低时，低压开关处于断开状态，这样水净化装置就进不了水，防止增压泵空转，起到保护作用。
为了进一步提高过滤效果，所述滤膜组件的净水出水口连接有一后置活性炭过滤器，所述后置活性炭过滤器的进水口处设有压力罐和高压开关，所述后置活性炭过滤器的进水口通过高压开关与滤膜组件的净水出水口连接，净化水从后置活性炭过滤器的出水口排出。该高压开关是联接在净水出水口后压力罐前的控制开关，主要作用是防止压力罐压力过高，避免增压泵满转。
优选的，所述滤膜组件的废水出水口上设有一废水电磁阀，在停止使用该水净化装置时，通过关闭废水电磁阀，以免废水常流。
上述的滤膜组件的滤膜滤芯为反渗透膜滤芯或超滤膜滤芯，实施例中优选的反渗透膜滤芯，采用反渗透技术，过滤精度高，能够有效的去除水中钙、镁、细菌、有机物、无机物、金属离子和放射性物质等，经过该滤膜滤芯净化出的水能够直接作为饮用净水使用。
本发明的有益效果：该水净化装置通过在滤芯组件和滤膜组件上安装带身份识别芯片的滤芯，利用身份识别器对滤芯进行自动识别匹配，只有安装具有身份识别芯片的原厂滤芯才能通过身份识别配对，滤芯配对成功后该水净化装置才能正常工作，所采用的无线射频识别技术能够自动识别滤芯产品并获取相关数据，识别工作无须人工干预，可同时识别多个目标，响应速度快，无机械故障、寿命长、抗恶劣环境，有效打击仿冒伪劣产品，保证滤芯产品的质量和过滤水的饮用卫生。
附图说明
下面结合附图对本发明的具体实施方式做进一步的说明。
图1是本发明的水净化装置的过滤原理示意图；
图2是本发明中电子标签与读取器的原理示意图。
具体实施方式
参见图1，本发明提供的一种基于滤芯识别防伪的水净化装置，包括滤芯组件1、增压泵2和滤膜组件3，所述滤芯组件1的进水口和出水口分别连接供水管和增压泵2，所述增压泵2的出水口与滤膜组件3的进水口连接，所述滤膜组件3上设有净水出水口和废水出水口，自来水经过滤芯组件1进行粗过滤，然后利用增压泵2将水增压通过滤膜组件3进微过滤，得到较好的过滤效果。为了避免使用仿冒伪劣的滤芯产品而降低水净化装置的过滤效果，在所述滤芯组件1和滤膜组件3上设置身份识别芯片，该身份识别芯片安装位于滤芯组件1和滤膜组件3的滤芯上，并在水净化装置上安装身份识别器用于与身份识别芯片进行身份识别验证，所述增压泵2通过与身份识别器连接，只有更换安装有身份识别芯片的原厂滤芯才能与水净化装置上的身份识别器匹配，当且仅当滤芯上各个身份识别芯片通过与身份识别器配对成功后，所述身份识别器才输出控制信号驱动增压泵2工作；当滤芯上的身份识别芯片与身份识别器无法匹配或安装无身份识别芯片的滤芯时，身份识别器阻断增压泵2的通电，使增压泵2无法正常工作，从而不能进行过滤。
参见图2，本发明采用非接触式的射频自动识别技术进行身份识别，适合短距离非接触式识别验证，优选的实施方式为，所述身份识别芯片与身份识别器分别为电子标签4与读取器5，所述电子标签4由非接触式IC41以及围绕所述非接触式IC41设置的射频天线42构成，所述射频天线42是印刷天线、刻蚀天线，或绕制天线，所述射频天线以圆形、三角形、方形、椭圆形或不规则型任意形式环绕非接触式IC，所采用的射频天线的线宽范围为0.5-50mm，根据不同材质的滤芯使用不同材质的射频天线42，保证射频信号传输的稳定性。所述读取器5为RFID读取器，所述非接触式IC41为射频识别芯片，其工作频率为840 ～ 960MH，该电子标签4没有内部供电电源，其内部集成电路通过接收到的电磁波进行驱动，这些电磁波是由RFID读取器5发出的，当电子标签4接收到足够强度的讯号时，可以向读取器5发出数据，这些数据不仅包括唯一的ID识别号，还可以包括预先存在于非接触式IC41内数据储存器中的数据，且数据储存器内的数据可随时更新、可读写，记录包括产品的厂家信息、生产日期、校验密码等数据。
为了提高实用性，所述非接触式IC41内还设置有记时器，所述记时器能够实时记录滤芯的累计工作时间，当到达滤芯的使用期限时，所述非接触式IC41会发出控制信号中断增压泵2的通电使其停止工作，并发送信号提醒更换滤芯，具体是通过在水净化装置主体上设置提示灯进行提醒。
在本实施例中采用的滤芯组件1包括壳体和滤芯，滤芯安装固定在壳体内，由于电子标签4体积小，容易封装，可以将电子标签4封装嵌入在滤芯上，所述读取器5安装滤芯组件1的壳体上，所述电子标签4与读取器5配对成功后，不影响的水净化装置的运作。
优选的，所述滤芯组件1包括有最少两个滤芯，所述滤膜组件3包括有最少一个滤膜滤芯，每个滤芯和滤膜滤芯上都设置有电子标签4，具体的，本实施例中，将电子标签4分别安装在滤芯组件1的滤芯上以及滤膜组件3的滤膜滤芯上，而可以单独使用一个读取器5识别该两过滤组件上的电子标签4，此时，读取器5安装在水净化装置上能够与各个电子标签4射频识别的位置范围内，即只要安装在能够与各个电子标签4进行射频感应的位置上，都可以实现身份识别功能，其中，读取器5的射频识别范围为50cm以内；也可以对应滤芯组件1和滤膜组件3分别配置一个读取器5进行识别工作，此时，读取器5安装在所在过滤组件的外壳上。
所述滤芯组件1的滤芯中至少包括有一个PP棉滤芯和一个活性炭滤芯，自来水经过PP棉滤芯进行粗过滤，通过活性炭滤芯进行吸附过滤，PP棉滤芯能有效去除所过滤液体中的各种颗粒杂质，活性炭滤芯采用粒径合理，比表面积大于 1000㎡/g 的高效活性碳，使其既有上层特效过滤又有下层高效吸附等功能，大大提高产水净化程度和碳的使用寿命，有效去除水体中异味、有机物、胶体、铁及余氯等，对于降低水体的浊度、色度，净化水质，减少对滤膜的污染等也有很好的作用，根据实际需要可以设置多级滤芯进行过滤，以提高过滤效果。
上述的滤膜组件3的滤膜滤芯为反渗透膜滤芯或超滤膜滤芯，实施例中选用反渗透膜滤芯，采用反渗透技术，过滤精度高，能够有效的去除水中钙、镁、细菌、有机物、无机物、金属离子和放射性物质等，经过该滤膜滤芯净化出的水能够作为饮用净水使用。
优选的，所述滤膜组件3的废水出水口上设有一废水电磁阀，在停止使用该水净化装置时，通过关闭废水电磁阀，以免废水常流。
当水净化装置需要更换滤芯组件1或滤膜组件3上的滤芯时，必须采用原厂的滤芯才能通过验证匹配使用。具体的自动识别配对过程为，当滤芯组件1更换滤芯或滤膜组件3更换滤膜滤芯时会自动进入识别工作，由读取器5通过内置的天线发出射频信号，电子标签4通过射频天线42接收到读取器5发出的读取指令后，返回射频信号进行响应，把产品的信息传递给读取器5，同时进行密码校验配对，验证产品信息与校验密码是否一致，识别工作无须人工干预，可同时识别多个目标，即滤芯组件1内的各个滤芯以及滤膜组件3内的各个滤膜滤芯同时进行身份识别，且各个滤芯上的身份识别芯片都与身份识别器配对成功后，所述身份识别器才输出控制信号驱动增压泵2工作，响应速度快，无机械故障、寿命长，能够在恶劣环境下工作。
优选的，所述增压泵2与滤芯组件1之间设有进水电磁阀10和低压开关9，所述低压开关9连接在进水电磁阀10的进水端，所述进水电磁阀10的出水端连接增压泵2。通过进水电磁阀10进行进水控制，所述低压开关9主要是用于保护增压泵2，当水压低时，低压开关9处于断开状态，这样水净化装置就进不了水，防止增压泵2空转，起到保护作用。
为了进一步提高过滤效果，所述滤膜组件3的净水出水口连接有一后置活性炭过滤器6，所述后置活性炭过滤器6的进水口处设有压力罐7和高压开关8，所述后置活性炭过滤器6的进水口通过高压开关8与滤膜组件3的净水出水口连接，净化水从后置活性炭过滤器6的出水口排出。该高压开关8是联接在净水出水口后压力罐7前的控制开关，主要作用是防止压力罐7压力过高，避免增压泵2满转。
本发明的水净化装置采用的无线射频识别技术能够自动识别滤芯产品，识别工作无须人工干预，只有安装具有身份识别芯片的原厂滤芯才能通过身份识别配对，滤芯配对成功后该水净化装置才能正常工作，响应速度快，无机械故障、寿命长、抗恶劣环境，有效打击仿冒伪劣产品，保证滤芯产品的质量和过滤水的饮用卫生。
以上所述，只是本发明的较佳实施例而已，本发明并不局限于上述实施方式的结构，只要其以相同的手段达到本发明的技术效果，都应属于本发明的保护范围。
