具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本发明的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如前所述，喷墨打印机，是采用墨点可控技术输出图像的打印机，自出现以来，由于其具有独特的优势，在国内外得到了广泛的应用。喷墨打印机通过对其墨盒中的负压进行控制，使得墨水在负压的作用下从喷头中喷出，从而实现喷墨打印。因此，喷墨打印机的稳定运行与其负压控制***的关系是非常密切的，如果负压控制***出现异常，可能导致喷墨打印机的运行出现异常。
目前，喷墨打印机的负压控制***中，一般采用可编程逻辑控制器(Programmable Logic Controller，PLC)或者单片机对墨盒的负压控制器进行单一控制，从而实现对墨盒内负压的控制。具体的，图1为现有的墨盒负压控制原理的示意图，如图1所示，由PLC或者单片机单一地控制墨盒负压控制器，当PLC或单片机出现故障或者断电时，墨盒负压控制器的控制信号丢失，使得墨盒内立即失去负压，导致喷头大量漏墨，造成墨水浪费。
本发明提供的墨盒负压控制装置，可用于解决现有技术中可能存在的大量漏墨问题，有效减少墨水浪费。
本发明提供的墨盒负压控制装置可用于所有类型的喷墨打印机，例如可用于陶瓷喷墨打印机，还可用于其他类型的喷墨打印机。后续实施例为了描述方便，均以陶瓷喷墨打印机的墨盒负压控制装置为例进行说明。
下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图2为本发明提供的墨盒负压控制装置实施例一的结构示意图，如图2所示，本实施例的墨盒负压控制装置，包括：喷头40、进墨盒10、出墨盒20、进墨盒负压控制器11、出墨盒负压控制器21、主控制器30和切换控制器31。
主控制器30与切换控制器31连接，切换控制器31与进墨盒负压控制器11和出墨盒负压控制器21分别连接，进墨盒负压控制器11与进墨盒10连接，出墨盒负压控制器21与出墨盒20连接，进墨盒10的进墨口和出墨盒20的出墨口与喷头40连接。
主控制器30用于向切换控制器31发送负压模拟量信号和切换信号，所述切换信号用于指示是否允许由工作负压切换到保持负压。切换控制器31用于根据所述负压模拟量信号和切换信号确定目标负压模拟量，将所述目标负压模拟量发送给进墨盒负压控制器11和出墨盒负压控制器21。进墨盒负压控制器11用于根据所述目标负压模拟量对进墨盒10内的负压进行控制，出墨盒负压控制器21用于根据所述目标负压模拟量对出墨盒20内的负压进行控制。
可选的，主控制器30为PLC或单片机。
其中，所述负压模拟量信号包括进墨盒负压模拟量和出墨盒负压模拟量，从而切换控制器31可根据所述负压模拟量信号分别对进墨盒10和出墨盒20的负压进行调整。所述切换信号用于指示是否允许由工作负压切换到保持负压，所述工作负压是指喷头处于正常喷墨状态时墨盒的负压，所述保持负压是指当负压控制出现异常时为了防止喷头漏墨而使墨盒保持的负压。
具体的，主控制器30可以实时监测进墨盒10和出墨盒20的工作状态，所述工作状态包括但不限于负压参数和是否发生倒吸等，根据实时监测的墨盒的工作状态，确定进墨盒10和出墨盒20的负压调整量，从而得到负压模拟量信号。
主控制器30还可以根据需要向切换控制器31发送不同的切换信号，例如，当进墨盒10和出墨盒20工作状态正常时，向切换控制器31发送不允许切换信号，使得进墨盒10和出墨盒20处于工作负压；当主控制器30出现故障或者发送断电时，向切换控制器31发送的允许切换信号，使 得进墨盒10和出墨盒20切换为保持负压，避免由于墨盒内失去负压导致喷头大量漏墨。
切换控制器31接收到负压模拟量信号和切换信号后，根据所述负压模拟量信号和切换信号，确定目标负压模拟量，并将所述目标负压模拟量发送给进墨盒负压控制器11和出墨盒负压控制器21，例如：若所述切换信号为允许切换信号，则将预设的保持负压模拟量发送给进墨盒负压控制器11和出墨盒负压控制器21，从而使得进墨盒10和出墨盒20内的负压为保持负压，避免由于墨盒内失去负压导致喷头大量漏墨；若所述切换信号为不允许切换信号，则将从主控制器30接收到的所述负压模拟量信号发送给进墨盒负压控制器11和出墨盒负压控制器21，使得进墨盒10和出墨盒20内的负压为工作负压。
本实施例中，通过将主控制器30与切换控制器31连接，切换控制器31与进墨盒负压控制器11和出墨盒负压控制器21分别连接，并且，切换控制器31可以根据主控制器30发送的负压模拟量信号和切换信号，确定目标负压模拟量，并将所述目标负压模拟量发送给进墨盒负压控制器11和出墨盒负压控制器21，实现切换控制器31对进墨盒10和出墨盒20的负压冗余控制。当主控制器30故障或者发生断电等异常时，切换控制器31可以根据主控制器30发送的切换信号将进墨盒10和出墨盒20的工作负压切换为保持负压，使得进墨盒10和出墨盒20内保持一定的负压，避免由于墨盒内失去负压导致喷头大量漏墨，从而减少墨水浪费。
图3为本发明提供的墨盒负压控制装置实施例二的结构示意图，如图3所示，在上述实施例的基础上，本实施例的墨盒负压控制装置，还包括进墨盒夹管阀12和出墨盒夹管阀22。
进墨盒夹管阀12连接在进墨盒10和进墨盒负压控制器11之间，出墨盒夹管阀22连接在出墨盒20和出墨盒负压控制器21之间；进墨盒夹管阀12和出墨盒夹管阀22分别与主控制器30连接。
主控制器30还用于控制进墨盒夹管阀12和出墨盒夹管阀22的开闭。
具体的，主控器30可以实时监测进墨盒10和出墨盒20的工作状态，所述工作状态包括但不限于负压参数和是否发生倒吸等。主控制器30可以根据实时监测到的进墨盒10和出墨盒20的工作状态，控制进墨盒夹管 阀12和出墨盒夹管阀22的开闭，例如，当进墨盒10和/或出墨盒20发生倒吸时，将进墨盒夹管阀12和出墨盒夹管阀22关闭，当进墨盒10和出墨盒20未发生倒吸时，将进墨盒夹管阀12和出墨盒夹管阀22打开。
本实施例中，通过将进墨盒夹管阀12连接在进墨盒10和进墨盒负压控制器11之间，将出墨盒夹管阀22连接在出墨盒20和出墨盒负压控制器21之间，使得当主控制器30监测到进墨盒10和/或出墨盒20发生倒吸时，可以控制进墨盒夹管阀12和出墨盒夹管阀22关闭，从而防止进墨盒10内的墨水被倒吸进进墨盒负压控制器11以及后端管路中，并且防止出墨盒20内的墨水被倒吸进出墨盒负压控制器21以及后端管路中，保护器件不受损坏。
可选的，本实施例的墨盒负压控制装置，还可以包括进墨盒缓冲罐13和出墨盒缓冲罐23。
如图3所示，进墨盒缓冲罐13连接在进墨盒夹管阀12和进墨盒10之间，出墨盒缓冲罐23连接在出墨盒夹管阀22和出墨盒20之间。
进墨盒缓冲罐13用于容置由进墨盒10流向进墨盒负压控制器11的墨水，出墨盒缓冲罐23用于容置由出墨盒20流向出墨盒负压控制器21的墨水。
可以理解的，当进墨盒10发生倒吸时，即进墨盒10内的墨水流向进墨盒负压控制器11时，若主控制器30控制进墨盒夹管阀11关闭不及时，则可能会有少许的墨水流入进墨盒负压控制器11，从而造成进墨盒负压控制器11以及后端管路的损坏。
本实施例中，通过将进墨盒缓冲罐13连接在进墨盒夹管阀12和进墨盒10之间，使得当进墨盒10发生倒吸时，即使是在进墨盒夹管阀11关闭不及时的情况下，进墨盒缓冲罐13可以容置由进墨盒10流向进墨盒负压控制器11的墨水，使得墨水无法流入进墨盒负压控制器11以及后端管路，从而进一步保护了器件不受损坏。
可以理解的，出墨盒缓冲罐23的效果类似，此处不再赘述。
图4为本发明提供的墨盒负压控制装置实施例三的结构示意图，图5为本发明提供的墨盒负压控制装置实施例三的控制原理示意图，如图4和图5所示，在上述实施例的基础上，本实施例的墨盒负压控制装置，还包 括进墨盒负压传感器14和出墨盒负压传感器24。进墨盒负压传感器14设置在进墨盒缓冲罐13上，出墨盒负压传感器24设置在出墨盒缓冲罐23上；进墨盒负压传感器14和出墨盒负压传感器24分别与主控制器30连接。
主控制器30还用于根据进墨盒负压传感器14和出墨盒负压传感器24的输入信号，确定所述负压模拟量信号。
具体的，进墨盒负压传感器14可以获取进墨盒10的当前负压参数，出墨盒负压传感器24可以获取出墨盒20的当前负压参数，主控制器30可以根据进墨盒10和出墨盒20的当前负压参数，确定进墨盒10和出墨盒20的负压调整量，从而得到负压模拟量信号。
可选的，本实施例的墨盒负压控制装置，还可以包括进墨盒倒吸检测器15和出墨盒倒吸检测器25；进墨盒倒吸检测器15设置在进墨盒缓冲罐13上，出墨盒倒吸检测器25设置在出墨盒缓冲罐23上；进墨盒倒吸检测器15和出墨盒倒吸检测器25分别与主控制器30连接。
主控制器30还用于根据进墨盒倒吸检测器15和出墨盒倒吸检测器25的输入信号，确定所述负压模拟量信号和切换信号。
具体的，进墨盒倒吸检测器15可用于检测进墨盒10内的墨水是否发生倒吸，出墨盒倒吸检测器25可用于检测出墨盒20内的墨水是否发生倒吸。主控制器30根据进墨盒10和出墨盒20是否发生倒吸，确定所述负压模拟量信号和切换信号，例如：若进墨盒10和出墨盒20均未发生倒吸，则根据进墨盒10和出墨盒20的当前负压参数确定所述负压模拟量信号，并将切换信号置为不允许切换；若进墨盒10和出墨盒20均发生倒吸或者其中一个发生倒吸，则将所述负压模拟量信号置为零，将切换信号置为不允许切换。需要说明的是，上述的确定负压模拟量信号和切换信号的方法仅为示例，本发明并不以此为限。
可选的，主控制器30具体用于根据进墨盒倒吸检测器15和出墨盒倒吸检测器25的输入信号，控制进墨盒夹管阀12和出墨盒夹管阀22的开闭。例如：若主控制器30判断进墨盒10和出墨盒20均未发生倒吸，则控制进墨盒夹管阀12和出墨盒夹管阀22打开；若主控制器30判断进墨盒10和出墨盒20均发生倒吸或者其中一个发生倒吸，则控制进墨盒夹管 阀12和出墨盒夹管阀22关闭。
可选的，切换控制器31，具体用于判断所述负压模拟量信号和切换信号是否满足预设条件，所述预设条件为：所述负压模拟量信号不满足预设范围，并且，所述切换信号用于指示允许由工作负压切换为保持负压；若是，则将预设的保持负压模拟量作为所述目标负压模拟量，若否，则将所述负压模拟量信号作为所述目标负压模拟量。
可选的，切换控制器31，还用于当所述负压模拟量信号和切换信号满足预设条件时，向主控制器30发送报警信号。
可选的，切换控制器31，还用于当检测到自身故障时，将所述负压模拟量信号发送给进墨盒控制器11和出墨盒控制器21，并向主控制器30发送报警信号。
下面结合图5，详细描述本实施例提供的墨盒负压控制装置的墨盒负压控制过程。
主控制器30根据进墨盒倒吸检测器15和出墨盒倒吸检测器25的输入信号，判断是否发生倒吸。
若未发生倒吸，则主控制器30根据进墨盒负压传感器14和出墨盒负压传感器24的输入信号，确定进墨盒10和出墨盒20的负压调整量，得到负压模拟量信号；同时，主控制器30还判断进墨盒10和出墨盒20是否需要由工作负压切换为保持负压，若是，则将切换信号置为允许切换信号，若否，则将切换信号置为不允许切换信号；同时，主控制器30将进墨盒夹管阀12和出墨盒夹管阀22打开。
若发生倒吸，则主控制器30将进墨盒夹管阀12和出墨盒夹管阀22关闭，同时，将所述负压模拟量信号置为零，将切换信号置为不允许切换信号。
主控制器30将所述负压模拟量信号和切换信号发送给切换控制器31。
切换控制器31接收到所述负压模拟量信号和切换信号后，对所述负压模拟量信号和切换信号进行判断，实现对进墨盒10和出墨盒20的负压控制。例如：
若所述负压模拟量信号不满足预设范围，并且，所述切换信号为允许 切换信号(例如：主控制器30故障或者发生断电的场景)，则将预设的保持负压模拟量发送给进墨盒负压控制器11和出墨盒负压控制器21，使得进墨盒10和出墨盒20由工作负压切换为保持负压，也就是说，使进墨盒10和出墨盒20内的负压调整为所述预设的保持负压模拟量，从而避免由于墨盒失去负压导致喷头大量漏墨。同时，切换控制器31向主控制器30发送报警信号，以使主控制器30向用户提示报警信息。
若所述负压模拟量信号满足预设范围(例如：墨盒正常工作的场景)，则将从主控制器30接收到的所述负压模拟量信号发送给进墨盒负压控制器11和出墨盒负压控制器21，使得进墨盒10和出墨盒20继续为工作负压。
若所述切换信号为不允许切换信号(例如：进墨盒10和/或出墨盒20发生倒吸的场景)，由于在进墨盒10和/或出墨盒20发生倒吸的场景下，主控制器30已控制进墨盒夹管阀12和出墨盒夹管阀22关闭，使得进墨盒10和出墨盒20内可以保持一定的负压，从而喷头不会滴墨。同时，进墨盒夹管阀12和出墨盒夹管阀22关闭，也使得进墨盒10和出墨盒20内的墨水不会倒吸到进墨盒负压控制器11和出墨盒负压控制器21中，保护器件不受损坏。
若切换控制器31检测到自身发生故障，则在接收到主控制器30发送的负压模拟量信号和切换信号后，不进行上述判断，直接将所述负压模拟量信号发送给进墨盒负压控制器11和出墨盒负压控制器21。同时，切换控制器31向主控制器30发生报警信号，以使主控制器30向用户提示报警信息。
图6为本发明提供的喷墨打印机实施例的结构示意图，如图6所示，本实施例的喷墨打印机包括墨盒负压控制装置，其中，所述墨盒负压控制装置可采用上述任一实施例中墨盒负压控制装置的结构，其实现原理和技术效果类似，此处不再赘述。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或 者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
