Chip applied to ink box of ink-jet printer, ink box and control method thereof

Abstract

The invention discloses a chip applied to an ink box of an ink-jet printer, an ink box and a control method of the ink box. The chip comprises a circuit board, a storage on the circuit board and an excitation response analog circuit; the excitation response analog circuit comprises an oscillating circuit used for generating an periodic signal with the resonant frequency property which can be distinguished by the ink-jet printer; and the oscillating circuit comprises a low-voltage direct current generator, an oscillator, a controlled frequency divider and a coupling circuit. By adopting the chip, the periodic signal with the resonant frequency property which is precisely matched with the resonance state to be distinguished of the ink-jet printer can be automatically generated according to an excitation signal of the ink-jet printer, so that the ink-jet printer can be continuously used for printing after the periodic signal is detected; and the oscillating circuit in the chip of the ink box can be highly integrated, so that the area of the chip can be effectively reduced, and the cost can be saved as well.

Description

technical field [0001] The invention relates to the field of inkjet printers, in particular to a chip applied to an inkbox of an inkjet printer, an inkbox and a control method thereof. Background technique [0002] The printing information in the inkjet printer is not only recorded on the inkjet printer, but also recorded in the memory. The memory is generally installed on the circuit board and integrated with the circuit board as an ink cartridge chip installed on the ink cartridge, which is used to control the ink cartridge and the inkjet printer. The matching and the provision of printing information in the subsequent printing process. In the memory chip, initial information such as the ink cartridge model, color, and total amount of ink are recorded, as well as printing information such as the printing date obtained in the subsequent printing process, and the ink remaining in the ink cartridge. . [0003] In the existing technology, such as figure 1 As shown, in order ...

AI Technical Summary

Problems solved by technology

Due to the inconsistency in the number of turns and coil density of the inductance coil on different chips during production, the frequency of the resonance characteristic fed back to the inkjet printer by the excitation response analog circuit will deviate when some chips are in use.

In addition, in order to produce the resonance characteristics matching the sensor of the inkjet printer manufacturer, the volume of the inductor in the circuit is relatively large, resulting in a relatively large area of ​​the circuit board

At the same time, the cost of inductors continues to increase, making the cost of chips that use inductors to form LC oscillator circuits also increase.
