Ink cartridge having inner container and processing method therefor

A manufacturing method of an inner container type ink cartridge, comprising the following steps:

• S10, removing an upper cover of an original ink cartridge to obtain a cartridge shell;
• S20, electrically connecting an external control circuit board with an original control circuit board of the original ink cartridge, so that contacts on the original control circuit board communicate with the external control circuit board;
• S30, arranging an internal control circuit board at a corresponding position of an inner container;
• and
• S40, installing the inner container in the cartridge shell, so that internal contacts of the internal control circuit board of the inner container are electrically connected with the external control circuit board to obtain the inner container type ink cartridge;
• wherein a first chip of the external control circuit board or a second chip of the internal control circuit board is written with actual ink volume data of the inner container and an adopted program;
• and
• wherein the external control circuit board and the internal control circuit board are connected through a conductive piece.
