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是本发明的整机拆解结构示意图;
图2是本发明中电子标签与读取模块的原理示意图。
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空气净化器,包括净化器主体1,所述净化器主体1内设有控制电路以及用于安装滤芯2的净化腔,所述净化腔内安装有若干层滤芯2,各层滤芯2依次排列在净化腔内,所述净化器主体1上还设置有一空气净化面板3覆盖在净化腔上。所述滤芯2通过身份识别单元与净化器主体1匹配连接,该身份识别单元包括设置于各层滤芯2上的身份识别芯片与净化器主体1上的身份识别器,所述身份识别器与控制电路连接,当滤芯2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2时,身份识别器阻断控制电路的通电,使控制电路无法正常工作,只有安装上具有身份识别芯片的滤芯2,身份识别芯片与身份识别器进行配对成功后,控制电路才能通电使空气净化器进入正常工作。为了进一步达到防伪的目的,需要各层滤芯2上的身份识别芯片同时与身份识别器成功匹配才有效通过验证,否则空气净化器无法运行。
参见图2所示,本发明采用非接触式的射频自动识别技术作为身份识别单元的一种优选的实施方式,适合短距离非接触式识别验证,具体的,所述的身份识别芯片与身份识别器分别为电子标签5与读取模块4,该读取模块4为RFID读取模块,读取模块4连接控制电路,所述电子标签5包括非接触式IC51以及围绕所述非接触式IC51设置的射频天线52,该非接触式IC51为射频识别芯片,其工作频率为13.56MHZ,该非接触式IC51内设有数据储存器,该电子标签5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,这些电磁波是由具有射频识别功能的读取模块4发出的。当电子标签5接收到足够强度的射频信号时,可以向读取模块4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IC51内数据储存器中的数据,且可以重复地新增、修改、删除数据储存器内的数据,方便信息的更新,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IC51内还设置有计时器,计时器能够实时记录滤芯2的工作时间,当到达使用期限时,非接触式IC51会发出停止指令,该指令发送至读取模块4上,经读取模块4传输至控制电路上进行转化,通过在净化器主体1上设置提示灯进行提醒,且将中断控制电路的通电使其无法继续工作,直至用户采取更换滤芯2的措施。
上述射频识别的工作原理:读取模块4向电子标签5发送一组固定频率的电磁波,非接触式IC51内有一个LC 串联谐振电路,其频率与读取模块4发射的频率相同,在电磁波的激励下,LC 谐振电路产生共振,从而使电容内有了电荷,在这个电容的另一端,接有一个单向导通的电子泵,将电容内的电荷送到另一个电容内储存,当所积累的电荷达到2V 时,此电容可做为电源为其它电路提供工作电压,将非接触式IC51内数据发射出去或接收读取模块4的数据。
具体的配对连接过程为,当滤芯2安装进净化器主体1内时自动进入识别工作时,由读取模块4通过内置的天线发出射频信号,电子标签5通过射频天线52接收到读取模块4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模块4,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,从而实现自动识别。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,能够在恶劣环境下工作,而本发明采用的电子标签5与读取模块4独立运行,方便安装拆卸,由于电子标签5体积小,容易封装,可以将电子标签5封装形成独立的模块嵌入安装在滤芯2上,可以在普通的空气净化器上加装该电子标签5与读取模块4两个功能部件,无需改动整机结构即可变成具有滤芯2防伪功能的空气净化器,使用方便。
优选的,上述的射频天线52是印刷天线、刻蚀天线,或绕制天线,该射频天线以圆形、三角形、方形、椭圆形或其它不规则形状环绕非接触式IC,所采用的射频天线的线宽范围为0.5-10mm。根据不同材质的滤芯2使用不同材质的射频天线52,保证射频信号传输的稳定性。
优选的,所述读取模块4与各层滤芯2上的电子标签5的距离在10cm以内,在该距离内,所述读取模块4能够很好地同时读取多个滤芯2上的电子标签5。所述电子标签5的射频信号穿透性强,在被覆盖的情况下,能够穿透纸张、木材、塑料等非金属或非透明的材质,并能够进行穿透性通信。
本发明采用的滤芯2的一种实施例,其结构包括框架和固定在框架上的过滤层,所述过滤层包括去除气体污染物的过滤层和去除固体颗粒物的过滤层,所采用的过滤层结构结构可以达到持久而有效的净化效果,同时不会影响滤芯2的通风性,过滤效果好。而上述的电子标签5是安装位于滤芯2的框架上,属于射频识别范围内。为进一步加强过滤效果,所述净化器主体1上设有风机,所述控制电路连接驱动风机抽风进行过滤。
需要说明的是,在不冲突的情况下,本发明中的实施例及实施例中的特征可以相互组合。
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。
