参见图1，现有一种彩色喷墨打印机具有机壳11，图1所示的喷墨打印机省略了机壳11的托板。机壳11内设有喷墨打印机的机芯12，并设有一根滑杆，打印字车14在电机（图1中不可见）的带动下沿着滑杆往复运动。打印字车14内设有转接板（图1中不可见），转接板通过排线13与机芯12进行通信。
打印字车14上可拆卸地安装有多个墨盒15，不同墨盒15内容纳有不同颜色的墨水。墨盒15的结构如图2所示。墨盒15具有盒体16，盒体16围成容纳墨水的腔体，腔体的下端设有出墨口17，腔体内的墨水通过出墨口17流出，并向打印字车14的供墨针供墨。
墨盒15的盒体16的外壁上安装有一块芯片18，芯片18具有基板，基板的一侧设有多个连接端子19，用于与转接板电连接。基板的另一侧设有存储器（图2中不可见），通常，该存储器为非易失性存储器，如EEPROM或者FLASH，其存储有与墨盒相关的信息，包括可变信息与不变信息，可变信息是随打印操作会不断变化的信息，如墨水余量、打印时长、打印纸张数量等信息，不变信息是不会随打印操作变化的信息，如墨盒型号、适用的喷墨打印机型号、墨水颜色等。
墨盒15安装到喷墨打印机的打印字车14后，喷墨打印机给芯片18上电，并读取存储在芯片18的存储器内的数据，判断墨盒15型号是否合适、墨盒15内剩余墨水量是否充足等。只有判断墨盒15型号合适且墨盒15内有充足的墨水后，喷墨打印机才能执行打印工作。
参见图3，芯片18的基板20的一个表面上设置有9个连接端子，多个连接端子排列成上下两行，其中位于上方的第一行包括四个连接端子，分别是连接端子21、22、23、24，位于下方的第二行包括五个连接端子，分别是连接端子25、26、27、28、29。这些连接端子划分为三组，第一组连接端子为与存储器电连接的连接端子，通常位于每一行连接端子的中间位置，例如连接端子22、23、26、27、28为用于与存储器连接的连接端子。位于第一行两端的两个连接端子21、24为检测端子，位于第二行两端的两个连接端子为高压端子25、29。
检测端子21、24可以具有多种功能，第一种功能是用于检测墨盒15是否安装到位，如果检测端子21、24与喷墨打印机侧相应的连接端子电连接，则可以认为墨盒已经安装到位。第二种功能是用于实现墨盒型号的识别，例如检测端子21、24可以与连接端子22、23有不同的短路连接方式，喷墨打印机通过检测检测端子21、24的电平来确定喷墨打印机的型号，从而判断墨盒15是否安装错误。
墨盒15内设置有传感器用于检测墨水余量，但传感器工作的时候需要被施加较高的电压，因此，高压端子25、29用于接收喷墨打印机提供的高压直流电并且加载在传感器的两端。然而，如果有墨滴滴落在多个连接端子之间，将导致多个连接端子之间发生短路的现象，例如墨滴滴落在连接端子21、25、26之间，一旦高压端子25被加载较高的直流电压，将导致连接端子26的电压较高。如果连接端子26是用于向存储器通过电能的连接端子，也被称为电源端子，由于存储器的工作电压通常是3.3伏左右，如果连接端子26被加载较高的电压将导致存储器烧毁，甚至影响喷墨打印机的工作。
为此，喷墨打印机的机芯内设置短路检测电路，通过对检测端子21的电压进行检测判断是否出现短路的现象，例如墨滴滴落到连接端子21、25、26之间，当高压端子25被加载较高的直流电压，则检测端子21的电压升高，一旦喷墨打印机检测到检测端子21的电压过高时，则断开向高压端子25加载高压直流电，避免因连接端子26的高压对存储器造成损坏。
但是，由于短路检测电路设置在喷墨打印机的机芯内，因此检测端子21的电信号需要传输至喷墨打印机后，喷墨打印机才能够对检测端子21的电平进行判断，然后再断开高压端子25的供电。通常，从检测到检测端子21的电平过高到断开高压端子25的供电往往需要几毫秒的时间，有可能导致存储器损坏。
现有的一些芯片上设置有短路检测线以及短路检测单元，该短路检测单元通过短路检测线检测芯片上的多个端子之间发生短路的情况。该短路检测单元内设置有两个开关器件，一旦通过短路检测线检测到芯片上的多个端子之间出现短路的情况，则短路检测单元将芯片上的两个特定的端子进行短路，使得喷墨打印机无法识别芯片上的存储单元，进而报错，并且停止向芯片加载高压信号。但是，这种方式需要喷墨打印机对芯片的存储单元是否异常进行判断，并且在确认存储单元异常后，才会停止向芯片加载高压信号，导致喷墨打印机仍然有较长的时间向芯片加载高压信号，容易对存储器造成损坏。
 技术问题
本发明的第一目的是提供一种能够在极短时间内检测多个连接端子是否出现短路现象并保护存储器的墨盒芯片。
本发明的第二目的是提供一种应用上述墨盒芯片的墨盒。
本发明的第三目的是提供一种具有上述墨盒的喷墨打印机。
技术解决手段
为实现本发明的第一目的，本发明提供的墨盒芯片包括基板，基板上设有存储器以及多个连接端子，多个连接端子包括多个与存储器电连接的第一端子，且多个连接端子还包括至少一个检测端子以及至少一个高压端子；其中，检测端子与高压端子之间设置有短路检测线，基板上还设置有短路检测电路，短路检测电路包括开关器件，短路检测线与开关器件的控制端连接，且开关器件的两端分别连接至高压端子与预设电平，预设电平的电压低于高压端子的工作电压。
一个优选的方案是，短路检测线与检测端子之间具有间隙，且短路检测线与高压端子之间具有间隙。
进一步的方案是，在至少一个方向上，检测端子与短路检测线重叠，高压端子与短路检测线重叠。
更进一步的方案是，检测端子包括第一检测端子与第二检测端子，高压端子包括第一高压端子与第二高压端子，第一检测端子与第一高压端子相邻，第二检测端子与第二高压端子相邻；短路检测线包括位于第一检测端子与第一高压端子之间的第一段，短路检测线还包括位于第二检测端子与第二高压端子之间的第二段。
更进一步的方案是，开关器件的数量为两个，第一高压端子连接至第一开关器件，第二高压端子连接至第二开关器件。
更进一步的方案是，多个第一端子包括一个电源端子，开关器件连接至电源端子。
更进一步的方案是，开关器件为高电平导通的开关器件。这样，一旦发生短路的情况，短路检测线的电压变为高电平，此时开关器件导通，确保短路检测的准确性。
为实现上是的第二目的，本发明提供的墨盒包括盒体，盒体围成一个容纳腔，并且，盒体的外壁上设置有上述的墨盒芯片。
为实现上是的第三目的，本发明提供的喷墨打印机包括机体，机体内安装上述的墨盒。
 有益效果
本发明在检测端子与高压端子之间设置短路检测线，一旦有墨滴滴落在检测端子与高压端子之间，则短路检测线必然与检测端子、高压端子发生短路，这样，电路检测电路随即检测到多个连接端子之间的短路，开关器件导通，高压端子连接至预设电平，从而使得高压端子的电压被降低，避免对存储器造成损坏。
由于本发明是通过开关器件将高压端子与预设电平电连接，因此，一旦出现短路的情况，高压端子的电平直接降低至预设电平，整个过程并不需要喷墨打印机进行任何判断操作，从检测到短路到将高压端子的电平降低的时间非常短，从而快速的对存储器进行保护，相比起现有的短路保护方案，本发明能大幅度提高短路响应时间，从而减少存储器被加载高压信号的时间，更加有效的避免存储器损坏。
并且，短路检测线与检测端子、高压端子之间均具有间隙，也就是墨滴没有滴落在基板前，短路检测线并不会与检测端子、高压端子短路，从而实现对墨滴滴落的情况检测。
另外，在不同的方向上，短路检测线与检测端子、高压端子都重叠，不管墨滴的形状如何，都能够确保在检测端子与高压端子发生短路时，短路检测线必然检测到短路情况的发生，提高短路检测的准确性。
此外，两个相邻的高压端子与检测端子之间均设置有一段短检测线，这样可以确保墨滴在基板上与任一个检测端子、高压端子接触时，短路检测线均能够检测到短路情况的发生，避免短路检测的延迟。
并且，每一个高压端子均连接至一个开关器件，且每一个开关器件均在短路检测线检测到高压信号时导通，这样，一旦出现短路的情况，两个开关器件都导通，两个高压端子的电平信号都被降低，从而避免存储器损坏。
此外，将开关器件连接至电源端子，由于向存储器供电的电源端子的电压很低，通常只有3.3伏，且高压端子被加载高压直流电压时电源端子通常不被加载电压，即电源端子为0伏，因此能够将高压端子的电压降低，避免存储器损坏。

以下结合附图及实施例对本发明作进一步说明。
 本发明的实施方式
本发明的墨盒是安装在喷墨打印机上的墨盒，下面结合各实施例对本发明进行详细说明。
墨盒芯片实施例：
本实施例的墨盒芯片为安装在喷墨打印机用墨盒的墨盒芯片，其具有一块基板40，基板40的一面设有多个连接端子，如图4与图5所示，多个连接端子排列成两行，其中位于上方的第一行包括四个连接端子，分别是连接端子41、42、43、44，位于下方的第二行包括五个连接端子，分别是连接端子45、46、47、48、49。在基板40的另一面设置有存储器55，存储器55为EFFROM或者FLASH等非易失性存储器。
本实施例中，基板40上的多个连接端子划分为三组，第一组连接端子为第一连接端子42、43、46、47、48，多个第一连接端子包括电源端子VCC、时钟信号端子CLK、数据端子DAT、片选端子SC以及接地端子GND等，第一连接端子与存储器55电连接。从图5可见，这些连接端子位于每一行连接端子的中间位置。优选的，五个第一端子中的一个为电源端子，喷墨打印机向该电压端子加载低压直流电压以提供存储器55工作所需要的电源，通常，电源端子的工作电压是3.3伏。
第二组连接端子为第一行两端的两个连接端子41、44，连接端子41、44为检测端子，第三组连接端子为位于第二行两端的两个连接端子45、49，这两个连接端子为高压端子。
在墨盒内设置有工作电压较高的器件，例如用于检测墨水余量的传感器，如晶体震荡器，高压端子45、49分别连接至传感器的两端。喷墨打印机需要检测墨水余量时，向高压端子45、49加载较高的直流电压以使得晶体震荡器产生震荡信号。但是，由于墨水余量的检测工作并不是实时进行的，通常是在一次打印操作开始前或者打印操作完毕后才进行，因此，高压端子45、49并不是实时被加载较高的直流电压，而是在特定的时刻才被加载较高的直流电压。通常，喷墨打印机向高压端子45、49加载的直流电压是25伏以上，如果高压端子45、49与第一端子短路，较高的直流电压将对存储器55造成损坏。
为了避免高压端子与第一端子发生短路时存储器被不适当的加载高压直流电而损坏存储器，本实施例中，在基板40上设置短路检测线50，优选的，短路检测线50是通过覆铜的方式形成在基板40上，例如在制作芯片的电路板时，与多个连接端子一并以覆铜的方式制作而成。此外，短路检测线50并不与检测端子41、44、高压端子45、49物理连接，从图4可见，短路检测线50与检测端子41、44、高压端子45、49之间均具有间隙。
本实施例中，检测端子41与高压端子45相邻布置，两个端子分别位于第一行端子与第二行端子的最左端，而检测端子44与高压端子49相邻布置，两个端子分别位于第一行端子与第二行端子的最右端。此外，沿着基板40的长度方向，即图5中X方向，检测端子41与高压端子45部分重叠，并且，检测端子44与高压端子49也是部分重叠的。而沿着基板40的宽度方向，即图5中Y方向，检测端子41与高压端子45部分重叠，并且，检测端子44与高压端子49也是部分重叠的。
短路检测线50包括第一段51以及第二段52，如图4所示，第一段51位于检测端子41与高压端子45之间，第二段52位于检测端子44与高压端子49之间。并且，第一段51与第二段52均呈弯折形状，以避免与检测端子41、44、高压端子45、49物理连接。
在芯片的基板40上设置有短路检测电路60，优选的，短路检测电路60位于基板40设置连接端子的另一面，例如，当芯片安装到墨盒的时候，设置有连接端子的一面朝外，而设置有存储器55、短路检测电路60的一面朝向墨盒的盒体。本实施例中，两个高压端子45、49以及短路检测线50均连接至短路检测电路60。
参见图6，短路检测电路60内设置有两个开关器件，本实施例中，每一个开关器件均为高电平导通的高压场效应管，分别为场效应管T1与场效应管T2。其中，场效应管T1连接至高压端子45，场效应管T2连接至高压端子49。场效应管T1的栅极为场效应管T1的控制端，其连接至短路检测线50，漏极与高压端子45连接，源极连接至预设电平，本实施例的预设电平可以是0伏。当然，场效应管T1的源极也可以接地。
优选的，场效应管T1的源极连接至电源端子。由于喷墨打印机在检测墨盒的墨水余量时，并不会对存储器55进行读写操作，因此，喷墨打印机向高压端子45、49加载较高的直流电压时，并不会向电源端子记载低压直流电，此时电源端子的电压为0。
相同的，场效应管T2的栅极连接至短路检测线50，漏极与高压端子49连接，源极连接至预设电平，例如，连接至电源端子。此外，短路检测线50还通过电阻R1连接至电源端子VDD。
正常工作时，基板40没有墨滴时，高压端子45与检测端子41不会发生短路，短路连接线50与高压端子45不会电连接，因此，短路连接线50为低电平状态，此时，场效应管T1与场效应管T2均不导通。并且，由于高压端子45与第一端子之间均不会电连接，因此，存储器55不会接收到高压直流电压，存储器55并不会损坏。
一旦有墨滴滴落在基板40上并导致高压端子45与检测端子41之间发生短路，由于短路检测线50位于高压端子45与检测端子41之间，因此短路检测线50也会与高压端子45短路，此时，短路检测线50上形成较高的直流电压，这样，场效应管T1与场效应管T2均导通。由于此时电源端子并未被加载电压，因此，电源端子的电压为0，而场效应管T1导通后，高压端子45与电源端子连通，此时，高压端子45的电压瞬间被拉低，避免过高的电压加载到存储器55上而导致存储器55损坏。
相同的，如果高压端子49与检测端子44之间发生短路，短路检测线50的第二段52也会与高压端子49发生短路，这样，短路检测线50的电压为高电平信号，场效应管T2导通，高压端子49与电源端子连通，由于电源端子的电压较低，高压端子45的电压瞬间被拉低从而避免存储器55损坏。
在基板40上的墨滴被清除后，即使高压端子45、49被加载较高的电压，短路检测线50也不会形成高电平信号，场效应管T1与T2也不会导通，此时，形成在高压端子45、49的高压信号并不会对存储器55造成损坏。
由于短路检测电路60设置在基板40上，因此，一旦出现高压端子45、49与短路检测线50发生短路的现象，高压端子45、49的电压将瞬间被拉低，相比起由喷墨打印机来检测检测端子41、44的电平信号来判断是否出现短路现象并断开向高压端子45、49的供电，本发明能够在更短的时间内对存储器55进行保护。通过实验，应用本发明的方案，从高压端子45与短路检测线50出现短路开始到高压端子45的电平信号被拉低，所需要的时间只需要10微秒，远远小于现有技术从高压端子45与检测端子41发生短路到断开向高压端子45供电的时间，正是由于对存储器55保护时间的缩短，能够有效避免存储器55损坏。
此外，由于短路检测电路60所使用的电子元件非常少，成本很低，墨盒芯片所增加的生产成本不高。
墨盒实施例：
本实施例具有一个壳体，壳体围成一个容纳墨水的腔体，在腔体的下方设有与腔体连通的出墨口，腔体内的墨水可通过出墨口流出。并且，在壳体的一个外壁上可拆卸地安装有一块依据本发明上述实施例的墨盒芯片。
喷墨打印机实施例：
本实施例的喷墨打印机内设置有机体，机体内形成有容纳上述墨盒的容纳腔。
最后需要强调的是，本发明不限于上述实施方式，所使用的开关器件不一定是场效应管，可以使用三极管替代场效应管，或者检测端子、高压端子在基板上的位置的改变，这些改变也应该包括在本发明权利要求的保护范围内。
工业应用性
本发明的墨盒芯片可以安装在墨盒上，且墨盒可以安装在喷墨打印机上，喷墨打印机工作时，可以控制墨盒内的墨水喷出并实现打印的操作。本发明通过在芯片上设置短路检测线以及短路检测电路，能够在发生短路后的极短时间内将高压端子的电平降低，避免对存储器造成损坏。
