Ink box of ink-jet printer

Abstract

The invention discloses an ink box of an ink-jet printer. The ink box comprises a main ink supply chamber, a backup ink supply chamber and an auxiliary ink supply chamber, wherein the backup ink supply chamber and the auxiliary ink supply chamber are separated through a partition plate. An ink outlet is formed in the lower side of the main ink supply chamber, a slide is arranged on the upper side of the main ink supply chamber, one side of the slide is communicated with the outside, and a piston is arranged in the slide. A V-shaped stopping block is arranged on the lower surface of the auxiliary ink supply chamber, a flow channel which is arranged in an inclined mode is arranged in the piston, the width of the upper end of the flow channel is larger than the width of the lower end of the flow channel, the bottom of the inner side of the main ink supply chamber, the bottom of the inner side of the backup ink supply chamber and the bottom of the inner side of the auxiliary ink supply chamber are all inclined surfaces, and an air filter screen is arranged on an air inlet above the auxiliary ink supply chamber. The ink box of the ink-jet printer is simple in structure and reasonable in design. Due to the fact that the air filter screen is arranged on the air inlet, dust can be effectively prevented from entering the ink box and the cleanness of ink in the ink chambers is guaranteed; due to the fact that the bottoms of the ink supply chambers are arranged to be the inclined surfaces, ink left at the bottom of the ink box after the ink box is used is less, and therefore resources are saved.

Description

technical field [0001] The invention relates to an ink box, in particular to an ink box for an ink jet printer. Background technique [0002] Inkjet printers can be divided into solid inkjet and liquid inkjet according to the working principle (now the latter is more common), and the liquid inkjet method can be divided into bubble type (canon and hp) and liquid piezoelectric ( epson). The bubble jet technology is to heat the nozzle to make the ink generate bubbles and spray it onto the printing medium, and the ink cartridge, the main component of the inkjet printer, is particularly important in the printing job. According to the ink cartridge based on the inkjet printer announced by the patent application number 201220403790.4, it mainly has the following disadvantages: the air inlet is easy to enter dust, and after a long time of use, the speed and smoothness of the ink output will be greatly reduced, which is difficult for people's work. It brings a lot of inconvenience,...

Problems solved by technology

According to the ink cartridge based on the inkjet printer announced by the patent application number 201220403790.4, it mainly has the following disadvantages: the air inlet is easy to enter dust, and after a long time of use, the speed and smoothness of the ink output will be greatly reduced, which is difficult for people's work. It brings a lot of inconvenience, and at the same time, some ink will remain at the bottom of the ink cartridge after use, which causes a waste of resources
