Ink box and jet printing equipment

Abstract

The invention discloses an ink box and printing equipment. The ink box comprises a shell, an ink storage cavity and an ink supply cavity are arranged in the shell; the ink supply cavity comprises a first cavity, a second cavity and a partition plate; the first cavity comprises a first channel and a second channel which are separated by the partition plate, one end of the first channel forms a first opening in the bottom wall of the ink storage cavity, the first channel is in communication with the ink storage cavity through the first opening, one end of the second channel forms a second opening in the bottom wall of the ink storage cavity, the second channel is in communication with the ink storage cavity through the second opening, and the other end of the first channel is in communication with the other end of the second channel through the second cavity. The partition plate is arranged in the narrow ink supply cavity, the wall attachment effect of fluid is improved, gas-liquid separation is facilitated, the ink supply cavity is of a double-channel structure, ink flows into the ink supply cavity from one channel, where the borne gravity of the ink is large, of the first channel or the second channel, and gas is discharged out of the ink supply cavity from the other channel and flows back to the ink storage cavity. Bubbles are effectively prevented from gathering in the ink supply cavity.

Description

technical field [0001] The invention relates to the technical field of printing consumables, in particular to an ink cartridge and a printing device with the ink cartridge. Background technique [0002] In the field of printing consumables, ink cartridges are commonly used consumables for printing equipment, and are usually designed as independent accessories and sold separately from the printer. Ink cartridges are independently designed and sold to perform three basic functions: to store liquid ink, to supply ink to the printing unit, and to adapt to the printing unit. The user installs the ink cartridge on the inkjet printing device, and the ink picker of the inkjet printing equipment is inserted into the ink cartridge through the ink outlet of the ink cartridge to absorb ink. [0003] However, because air is soluble in ink under the influence of pressure and temperature, it is difficult to completely separate the ink stored in the ink cartridge from the air during the ma...

AI Technical Summary

Problems solved by technology

When the volume of the sponge soaked in the ink is small, the more easily saturated sponge will lose the capillary action and cannot play the role of lifting the ink. The larger the sponge, the capillary action is more obvious, but it will occupy a larger volume of the ink storage chamber , the effect of ink supply will be affected during high-speed printing, and even ink breakage will occur. Although the cost is low, there are problems of low ink storage chamber capacity and insufficient ink supply.
