Abstract

A liquid level sensing method, a consumables verification method, a device, and a print box provided by the embodiments of the present application, the device includes a controller and M sensing units, and the M sensing units are heated by heating with the fluid container inside the fluid container. The M sensing units are respectively arranged at different height positions of the fluid container, wherein M ≥ 2; the M sensing units have different heating rates respectively, and can output different output Sensing data or curves of numerical ranges, and determining the environmental states of the M sensing units according to the sensing data or curves of different numerical ranges. In the embodiment of the present application, different sensing units heat up according to different heating rates respectively, and different sensing units can output sensing data or curves with different numerical ranges, and then can output sensing data or curves with different numerical ranges. Or the comparison result between the curve and the reference temperature to determine the height of the liquid level, and the detection result is highly reliable.

Description

technical field [0001] The present application relates to the technical field of printing equipment, and in particular, to a liquid level sensing method, a consumables verification method, a device and a printing box. Background technique [0002] Inkjet printing devices use ink cartridges to store ink and supply ink to the printheads according to printing needs. Ink remaining detection is an important detection task in inkjet printers. [0003] In the related art, the ink remaining amount is estimated by the chip on the ink cartridge. When the chip estimates that the ink is used up, the chip will transmit the ink end information to the printer, so that the printer prompts the ink end. [0004] However, the above method only relies on the chip to estimate the ink remaining amount, and the ink remaining amount information estimated by the chip is not accurate. Inaccurate ink remaining information will lead to the following two consequences: 1. When the ink cartridge still e...
