At this time, the ink outlet 210 of the ink cartridge is engaged with the ink taking needle 310, for example, the ink taking needle 310 is inserted into a hole of a rubber plug of the ink outlet 210, so that the ink communication between the inkjet printing apparatus and the ink cartridge is realized. The cartridge chip 450 mates with the spring contacts 320 to electrically connect the cartridge chip to the inkjet printing device.
Finally, it should be emphasized that the above-described embodiments are merely preferred examples of the utility model, which is not intended to limit the utility model. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
