Consumable chip, consumable container and charging method for power accumulation unit of consumable chip

Abstract

The invention provides a consumable chip, a consumable container and a charging method for a power accumulation unit of the consumable chip; the chip comprises an electronic module; the electronic module is provided with an interface unit, a control unit, a memory and the power accumulation unit, wherein the electronic module is further provided with a charging control circuit which controls the charging of the power accumulation unit, and the control unit is provided with an identification module which sends a control signal to the charging control circuit; the identification module stores an identification code of the consumable chip. The method comprises the steps as follows: the control unit receives information sent by an imaging device, the identification module judges whether an identification code contained in the information received by the control unit is the same as the identification code stored in the identification module, if yes, the control signal is sent to the charging control circuit, and the charging control circuit is conducted, the power accumulation unit is charged by the imaging device; and if not, the identification module controls the charging circuit to switch off. The invention can guarantee higher charging voltage of the power accumulation unit, and can prevent from influencing a data transfer operation caused by over-small charging amount of the power accumulation unit.

Description

technical field [0001] The invention relates to the field of printing, in particular to a consumable chip mounted on a printing consumable, a consumable container equipped with the consumable chip, and a charging method for the power storage unit of the consumable chip. Background technique [0002] As a common office equipment, printers provide great convenience for modern office. Existing printers are divided into inkjet printers and laser printers. Inkjet printers use ink cartridges containing ink as consumable containers to spray ink on paper to form text or patterns that need to be printed on paper; laser printers use ink cartridges containing toner The toner cartridge is used as a consumable container to form text or patterns that need to be printed on the medium. [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 c...

Problems solved by technology

Moreover, the other side of the substrate is provided with an electronic module electrically connected to the electrical contact 34, and an interface unit, a control unit, a non-volatile memory, a volatile memory, an electric storage unit, etc. are also arranged on the electronic module. The chip 33 also has the problem that the charging voltage of the electric storage unit is too low and the charging time is short and the charging capacity is small, which affects the work of the chip 33.

[0012] In addition, toner cartridges or toner cartridges can be detachably installed on most existing imaging equipment such as copiers, fax machines, or all-in-one machines as consumable containers. These chips also have the same problem as the ink cartridge chips, that is, the power storage unit charges less power, which cannot meet the data transfer needs of the chip
