Inconvenience caused by the ink cartridge not only causes waste, but also is not conducive to environmental protection.
- inkjet printers only record one serial number data. If the reinstalled ink cartridge is not the original ink cartridge, even if the reinstalled ink cartridge is an inked ink cartridge, the inkjet printer still considers that the installed ink cartridge can be used.

Waste, easy for users to use, is also conducive to environmental protection.
- the transformation determining unit stores the consumable margin threshold data, and the serial number data transformation condition is that the consumable margin contained in the current consumable container is smaller than the consumable margin threshold.

Description
本发明涉及一种芯片，具体地说，是一种安装在打印耗材容器上的芯片、装有这种芯片的耗材容器以及这种芯片的工作方法。本发明基于申请日为2009年10月22日、申请号为200910193345.2的中国发明专利申请，该申请的内容作为与本发明密切相关的参考文献引入本文。
现有墨盒体积通常较小，容纳的墨水不多，墨水消耗完毕后，用户往往将墨盒扔弃。由于墨盒的壳体11以及芯片13仍能使用，用户使用一次即将墨盒扔弃，不但造成浪费，还会造成环境污染。
因此，一些用户对墨水消耗完毕的墨盒进行灌墨，并对芯片进行复位，即恢复芯片中存储数据的初始值，然后将灌墨后的墨盒安装到喷墨打印机上重新使用。但是，现有喷墨打印机会记录当前安装墨盒的序列号数据，当墨盒内墨水消耗完毕后，喷墨打印机将记录该序列号对应的墨盒墨水消耗完毕，不能再使用。
由于灌墨后的墨盒仍使用原来的芯片13，芯片13内存储的序列号数据仍是原来的序列号数据，因此，灌墨后的墨盒安装到喷墨打印机后将无法使用，给用户重复使用墨盒造成不便，不但造成浪费，还不利于环境保护。
但部分喷墨打印机仅记录一个序列号数据，若重新安装的墨盒不是原墨盒，即使重新安装的墨盒也是灌墨后的墨盒，喷墨打印机仍认为安装的墨盒可以使用。这要求用户至少使用两个墨盒轮流安装到喷墨打印机上，给用户的使用操作带来不便。
参见图3，现有碳粉盒具有壳体21，壳体21围成容纳碳粉的腔体，壳体的外壁上设有一个芯片安装位22，芯片23安装于芯片安装位22上。与墨盒芯片类似，碳粉盒的芯片23也具有基板，基板上设有作为通信模块的电触点24，用于与激光打印机通信。
芯片23上还设有存储器（图中不可见），存储器内存储有一组序列号数据，并且每一碳粉盒的序列号数据也是唯一的，用户对碳粉盒灌粉后重新使用时也会遇到因芯片存储的序列号数据与激光打印机所记录的序列号数据相同而无法使用，给用户的使用带来不便。
本发明的主要目的是提供一种便于灌装耗材后重新利用耗材容器的芯片；
本发明的另一目的是提供一种方便用户重复使用的耗材容器；
本发明的再一目的是提供一种减少耗材容器对环境造成污染的芯片工作方法。
为了实现上述主要目的，本发明提供的芯片安装在耗材容器壳体上，其具有基板，基板上安装有通信模块及与通信模块连接的存储器，存储器存储有一组初始序列号数据，其中，存储器还存储有一组或一组以上的备用序列号数据，并设有一个标志位，标志位存储有一个用于标识当前使用序列号的标识值，存储器还设有用于判断是否满足序列号数据变换条件的变换判断单元以及根据变换判断单元输出的命令变换标志位所存储标识值的变换单元。
为实现上述的另一目的，本发明提供的耗材容器具有壳体，壳体围成容纳耗材的腔体，壳体的外壁上设有一芯片，芯片具有基板，基板上安装有通信模块及与通信模块连接的存储器，存储器存储有一组初始序列号数据，其中，存储器还存储有一组或一组以上的备用序列号数据，并设有一个标志位，标志位存储有一个用于标识当前使用序列号的标识值，存储器还设有用于判断是否满足序列号数据变换条件的变换判断单元以及根据变换判断单元输出的命令变换标志位所存储标识值的变换单元。
由此可见，耗材容器的芯片能在耗材容器工作过程中送出备用序列号数据，打印机即记录备用序列号数据，待耗材容器灌装耗材后重新安装到打印机时，复位后的芯片送出的初始序列号数据不同于打印机所记录的备用序列号数据，便于耗材容器的重复利用。
为实现上述的再一目的，本发明提供上述芯片的工作方法包括芯片上电后，根据标志位存储的标识值，送出相应的一组序列号数据；然后，芯片根据标志位所存储的标识值判断当前使用的序列号数据是否为初始序列号数据，如是，变换判断单元进一步判断是否满足序列号数据变换条件，若满足变换条件，变换单元变换标志位所存储的标识值。
由上述方案可见，芯片在耗材容器使用过程中变换标志位的标识值，即芯片将送出备用序列号数据，从而避免耗材容器灌装后不能使用的问题，减少耗材容器使用一次后扔弃所造成的浪费，便于用户的使用，也有利于环境保护。
一个优选的方案是，变换判断单元存储有耗材余量阈值数据，序列号数据变换条件是当前耗材容器内容纳的耗材余量小于所述耗材余量阈值。
可见，耗材容器使用过程中，当耗材余量低于耗材余量阈值时，变换单元即变换标识值，确保耗材容器内耗材消耗完毕前送出备用序列号数据，从而确保灌装耗材后的耗材容器重新安装到打印机后正常使用。
图1是一种现有墨盒的结构示意图；
图2是现有墨盒芯片的结构示意放大图；
图3是一种现有碳粉盒的结构分解图；
图4是本发明芯片实施例的结构框图；
图5是本发明芯片使用方法实施例流程图。
以下结合附图及实施例对本发明作进一步说明。
本发明的耗材容器既可以是安装到喷墨打印机内的墨盒，也可以是安装到激光打印机内的碳粉盒，下面以墨盒作为实施例对本发明进行描述。
本发明的墨盒可拆卸地安装到喷墨打印机中，与现有墨盒相同，墨盒具有壳体，壳体围成容纳墨水的腔体，并在壳体外壁上安装有芯片，芯片的结构框图如图4所示。
芯片具有一块基板30，基板30上设有多个与喷墨打印机电触点接触的电触点31，电触点31作为通信模块与喷墨打印机进行通信。当然，本实施例中芯片使用电触点31作为通信模块与喷墨打印机进行有线连接通信，实际应用时，还可以使用天线作为通信模块，与喷墨打印机进行无线通信。
基板上还设有一存储器32，存储器32内存储有一组初始序列号数据33，还存储一组备用序列号数据34。初始序列号数据33与备用序列号数据34不相同，并且均为喷墨打印机能够识别的序列号数据。
存储器32内还设有一个标志位35，标志位35内存储有一个标识值，优选地，标识值为一位二进制数值，并且使用二进制数“0”标识初始序列号数据33，使用二进制数“1”标识备用序列号数据34。也就是，当标识值为“0”时，芯片将送出初始序列号数据33，标识值为“1”时，芯片将送出备用序列号数据34。芯片生产厂家制造芯片时，标识值的初始值为“0”。墨盒安装到喷墨打印机后，首次送出的是初始序列号数据33。
存储器32还存储变换判断单元36以及变换单元37，变换判断单元36用于判断墨盒当前条件是否满足序列号数据变换条件，若满足变换条件，则向变换单元37发出变换命令，变换单元37即变换存储在标志位35内的标识值。
本实施例中，变换判断单元36存储有墨水余量阈值数据，并判断墨盒内墨水余量是否低于所存储的墨水余量阈值，即序列号数据变换条件是墨盒中墨水余量低于墨水余量阈值。
实际使用中，变换条件还可以打印时间、墨盒打印数量等作依据，例如使用打印时间作依据时，变换判断单元36内存储有打印时间阈值；当墨盒打印时间大于该打印时间阈值时，即向变换单元37发出变换命令。若使用打印介质张数的数量作为判断依据，变换判断单元36存储打印数量阈值，如打印页数、喷射墨滴数量等，并判断墨盒的打印数量是否大于该打印数量阈值，若大于则发出变换命令。
变换单元37接收到变换命令后，使标志位35存储的标识值做自加运算，标识值即从“0”变换为“1”，对应的序列数据即从初始序列号数据33变换为备用序列号数据34。这样，墨盒向喷墨打印机送出的序列号数据即为备用序列号数据34，喷墨打印机即记录当前的序列号数据为备用序列号数据34。
墨盒内墨水消耗完毕后，喷墨打印机记录序列号为备用序列号34的墨盒墨水消耗完毕。当墨盒灌墨后，芯片得以复位，标识值恢复为“0”。墨盒安装到喷墨打印机后，再次送出初始序列号数据33，喷墨打印机即判断墨盒送出的序列号数据不同于其记录的序列号数据，喷墨打印机即可正常工作。可见，使用本实施例的墨盒，能有效避免墨盒因序列号问题而无法正常工作，有利于环境保护。
下面结合图5说明芯片的工作过程。
墨盒安装到喷墨打印机后，芯片执行步骤S1，根据标志位35内存储的标识值送出对应的序列号数据，若标识值为“0”，则送出初始序列号数据33，若标识值为“1”，则送出备用序列号数据34。
然后，芯片执行步骤S2，判断当前标识值对应的序列号数据是否为初始序列号数据33，若不是，则表示芯片已经变换了标识值，执行步骤S5，与喷墨打印机正常通信。若当前标识值标识的是初始序列号数据33，则执行步骤S3，变换判断单元36判断当前墨盒内存储的墨水余量是否低于墨水余量阈值，若低于墨水余量阈值，则表示当前条件满足序列号数据变换条件，变换单元37使标识值做自加运算，即执行步骤S4。这样，标识值对应的序列号数据为备用序列号数据34。若墨盒内墨水余量大于墨水余量阈值，表示当前条件未满足变换条件，则执行步骤S5，与喷墨打印机正常通信。
当然，若使用打印时间、打印数量作为序列号数据变换判断条件时，上述方法步骤S3中，变换判断单元36则判断墨盒的打印时间是否大于存储的打印时间阈值，或者判断墨盒的打印数量是否大于打印数量阈值。
由上述方法可见，墨盒工作过程中将送出备用序列号数据，待墨盒灌墨后再次安装到喷墨打印机时，经过复位的芯片将送出初始序列号数据，这样即可避免墨盒因送出的序列号数据与喷墨打印机记录的序列号数据相同而无法正常工作，便于用户重复利用墨盒，减少浪费，也减少对环境的污染。
本发明的耗材容器还可以是碳粉盒，碳粉盒壳体的外壁上安装有芯片，芯片具有基板，基板上设有电触点以及与电触点连接的存储器，存储器内存储有一组初始序列号数据以及一组备用序列号数据，并设有标志位，其存储的标识值用于标识两组序列号数据。当然，存储器还设有变换单元以及变换判断单元，当碳粉盒满足序列号变换条件时，变换单元即变换存储在标志位的标识值。这样，能避免重新灌粉后的碳粉盒因序列号问题而导致激光打印机无法正常使用。
当然，上述实施例仅是根据本发明构思的较佳实施方式，不能作为对权利要求的限制，本发明还可以有更多的变形，例如，存储器中存储多组的备用序列号数据，标志位的标识值为多位的二进制数据，分别标识多组序列号数据；又如，满足序列号数据变换条件时，变换单元不使标识值做自加运算，而是直接改写标识值的数据等，这些改变都是显而易见的。
最后需要强调的是，本发明不限于上述实施方式，诸如序列号变换判断条件的改变、通信模块的改变等微小变化，也应该包括在本发明权利要求的保护范围内。
本发明芯片的存储器内存储有二组以上的序列号数据，其中一组为初始序列号数据，耗材容器安装到打印机时使用初始序列号数据，并且在使用过程中，变换判断单元判断满足序列号数据变换条件后，变换单元变换标志位的标识值，芯片即送出备用序列号数据，打印机即记录当前的序列号数据为备用序列号数据。
待耗材容器重新灌装耗材后安装到打印机使用时，由于芯片经过复位处理，芯片将再次送出初始序列号数据，打印机判断当前的序列号数据不同于所记录的序列号数据，耗材容器即可正常使用。这样，用户重新灌装耗材后的耗材容器能重复使用，可有效地减少浪费。
