The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Referring to FIG. 1 , it is a schematic diagram of the overall structure of an anti-counterfeiting printing device for consumables provided by an embodiment of the present invention. Referring to FIG. 2 , it is a schematic functional structure diagram of an anti-counterfeiting printing device for consumables provided by an embodiment of the present invention. The anti-counterfeiting printing device for consumables mentioned in this application is, for example, a printer with anti-counterfeiting function of consumables. Taking the printing apparatus shown in FIG. 1 as an example, the printing apparatus includes an ejection unit 1 , an ink cartridge 2 , a maintenance unit 3 , an anti-counterfeiting comparison unit 4 , and a main body mounting part (not shown in the figure). In this embodiment, the identification information of the newly installed ink cartridge 2 is compared with the ink cartridge identification information recorded by the maintenance unit 3 by the anti-counterfeiting comparison unit 4, and according to the comparison result, it is determined whether the ink cartridge 2 is a legitimate ink cartridge, so as to realize the anti-counterfeiting of consumables.

Wherein, the spray unit 1 , the ink cartridge 2 and the maintenance unit 3 are respectively detachably mounted on the main body mounting portion. The ink cartridge 2 is connected to the ejection unit 1 to supply ink to the ejection unit 1 . The ink cartridge 2 is provided with an ink cartridge storage unit for storing the identification information of the first ink cartridge. Specifically, the ink cartridge storage unit may be, for example, a medium having a data storage function such as a memory chip. The identification information of the first ink cartridge may be, for example, the identification information that can only be read once by using the existing anti-counterfeiting technology.

The above-mentioned first ink cartridge identification information may be, for example, the serial number of the ink cartridge 2 . For example, when the printing equipment manufacturer produces the ink cartridge 2 for the printing equipment, the unique serial number of the ink cartridge 2 is provided, that is, a serial number can only correspond to one ink cartridge 2, so the serial number is used as the first ink cartridge identification information with accuracy. .

It can be understood that the anti-counterfeiting comparison unit 4 adopts a hardware unit including the structure of the comparator 5, and implements anti-counterfeiting of consumables by comparing the identification information of the first ink cartridge with the identification information of the second ink cartridge. If the comparison result indicates that the identification information of the first ink cartridge is consistent with the identification information of the second ink cartridge, it indicates that the identification information of the first ink cartridge is the identification information of the used ink cartridge, and if the current ink volume of the ink cartridge 2 is less than that of the ink cartridge recorded in the backup storage unit If the comparison result indicates that the identification information of the first ink cartridge is inconsistent with the identification information of the second ink cartridge, it indicates that the identification information of the first ink cartridge may be unused. If the identification information of the ink cartridge 2 is used, the currently installed ink cartridge 2 is determined as the legitimate ink cartridge 2, and the ink cartridge 2 is accessed normally.

In some practical application scenarios, take the printing device as a printer as an example. When the ink cartridge 2 is installed on the printer, the anti-counterfeiting comparison unit 4 of the printer reads the first ink cartridge identification information stored in the ink cartridge 2 chip, and the storage chip of the maintenance unit 3 does not store the first ink cartridge identification information, then the anti-counterfeiting comparison unit 4 will The read identification information of the first ink cartridge is stored on the storage chip of the maintenance unit 3 as the identification information of the second ink cartridge. When the maintenance unit 3 that has stored the identification information of the second ink cartridge is installed in the second printer, the anti-counterfeiting comparison unit 4 of the second printer can read the identification information of the second ink cartridge from the storage chip of the maintenance unit 3 . When the anti-counterfeiting comparison unit 4 of the second printer detects that a new ink cartridge 2 is installed, the second printer compares the ink cartridge identification information recorded by the maintenance unit 3 with the identification information of the newly installed ink cartridge 2, and determines according to the comparison result. Check whether the ink cartridge 2 is a legal ink cartridge to realize the anti-counterfeiting of consumables.
