Ink box chip and operating method thereof as well as ink box

Abstract

The invention provides an ink box chip and an operating method thereof as well as an ink box. The ink box chip comprises a substrate; a communication unit and an electronic module are arranged on the substrate; the communication unit comprises two detection contacts; the electronic module is provided with a control unit and a storage device, and is further provided with a piezoelectric signal generation circuit electrically connected with the detection contacts; the piezoelectric signal generation circuit is provided with a capacitor and a transformer; a primary coil of the transformer is connected in parallel with the capacitor; a secondary coil of the transformer is connected in series with a switching device; and a control end of the switching device is connected with the control unit. The operation method of the ink box chip comprises the following steps: the storage device receives the ink allowance data printed by an ink-jet printer, the controller judges whether the printed ink allowance data is lower than a threshold value or not; and if the printed ink allowance data is lower than a threshold value, a continuity signal is output to the switching device, and conversely a stop signal is output to the switching device. The chip can output a piezoelectric signal with different vibration frequencies, and avoids the condition that the ink box and the ink-jet printer abnormally work.

Description

technical field [0001] The invention relates to the printing field, in particular to an ink cartridge installed on an inkjet printer, a chip of the ink cartridge, and a working method of the ink cartridge chip. Background technique [0002] Inkjet printers are common printers that provide great convenience for modern offices. Inkjet printers use an ink cartridge containing ink as a consumable container to eject ink onto paper to form text or patterns that need to be printed on the paper. [0003] see figure 1 , an existing color inkjet printer has a casing 11, figure 1 The inkjet printer is shown with the chassis 11 omitted. The machine core 12 of ink-jet printer is provided with in the casing 11, and is provided with a slide bar 20, and printing word car 14 is in motor ( figure 1 (not visible in the middle) is driven to reciprocate along the slide bar 20. Printing word car 14 is provided with adapter plate ( figure 1 Invisible), the adapter board is electrically conne...

Problems solved by technology

[0013] However, since the piezoelectric signal generating circuit can only output a piezoelectric signal with a fixed oscillation frequency, but cannot simulate a signal with a higher oscillation frequency when the ink cartridge is empty, the inkjet printer still does not receive a signal with a higher oscillation frequency when the ink in the ink cartridge is insufficient. High piezoelectric signal, so that an alarm signal will not be issued to prompt the user to replace the ink cartridge, causing the user to use the ink cartridge that has been consumed, which often leads to the abnormal operation of the ink cartridge and the inkjet printer, which not only affects the printing quality, but also causes the ink cartridge and damage to inkjet printers
