Description

Consumable chip, chip assembly and consumable box Technical Field The application relates to the field of printing imaging, in particular to a consumable chip and a chip assembly for a consumable cartridge. Background In the field of printing and imaging, printing apparatuses (e.g., inkjet printers, laser printers, copies, multifunctional integrated machines, and the like) output recording materials (e.g., inks, carbon powders, and the like) on paper using printing consumables (e.g., consumable cartridges accommodating the recording materials such as head cartridges, ink cartridges, cartridge cartridges, and the like), thereby forming images and characters, and realizing a printing function of a predetermined target. The printing consumables are used as consumables, and the service life (service period) of the printing consumables is often shorter than that of the printing equipment, so that the printing consumables (consumable boxes) are designed into replaceable parts relative to the printing equipment, and when the recording materials are consumed, a user can take the used printing consumables off the printing equipment and then install new printing consumables. The user can thus continue to perform the print job on the printing apparatus. In order to record the service condition of the printing consumable and identify the source of the printing consumable, a consumable chip for recording related information is further arranged on the printing consumable, the consumable chip can be arranged on a consumable box, and in some cases, the consumable chip also provides functions of ink injection, allowance detection and the like, so that a spray head circuit, a liquid level sensor and other modules are further designed. When the recording material in the consumable box is consumed, the consumable chip is also written with corresponding information by the printing equipment, so that the consumable chip cannot be used continuously and must be discarded together with the consumable box. Therefore, many compatible consumable chips are available in the market, and after the compatible consumable chips are mounted on the consumable cartridge, the consumable cartridge may be continuously identified by the printing apparatus for use. This kind of life-span is limited, the consumable box that needs the unscheduled change, when installing in the printing apparatus, realizes the communication connection between consumable chip and the printing apparatus through the mode of physical electric contact generally, is provided with a plurality of signal contacts on this type of consumable chip, consequently, most printing apparatus has all designed the mechanism that detects whether the consumable box has normally been installed based on the consumable chip. In the related art, some printing devices send out signals with different time sequences to a plurality of signal contacts of a consumable chip, then a specific logic circuit of the consumable chip processes the signals, and a feedback contact of the consumable chip feeds back a logic processing result (signal combination) to the printing device, so that the printing device can judge whether the consumable chip is mounted on the printing device or not (thereby confirming whether the consumable box is mounted or not) based on the received signal combination. However, there may be signal interference between signals transmitted to the consumable chip through various signal contacts, so that the consumable chip cannot generate the expected signal combination of the printing apparatus, and the printing apparatus refuses to use the consumable chip. In some cases, other functions of the consumable chip may be normal under the influence of the yield of the manufacturing process, but the specific logic circuit is abnormal, and if the consumable chip cannot be used only because of the specific logic circuit, the whole consumable chip is scrapped. Therefore, in order to improve the accuracy of detecting that consumable chips (or consumable cartridges) have been mounted and to reduce the potential for consumable chip scrap, a corresponding solution is needed in the market. Disclosure of Invention In view of this, the present application provides a consumable chip, a chip assembly and a consumable cartridge, which are beneficial to improving the accuracy of the mounting detection of the consumable cartridge and reducing the potential rejection. In one aspect of the application, a consumable chip for a consumable cartridge is provided, the consumable chip being mounted on the consumable cartridge in cooperation with a second chip, the consumable chip receiving signals from and outputting signals to a printing apparatus when the consumable cartridge is mounted on the printing apparatus, wherein the consumable chip comprises a first status output circuit, the second chip comprising a second status output circuit for generating a second mounting status signal from a plurality of signals r
