An ink cartridge capable of automatic liquid supply and waste liquid discharge

Abstract

The invention discloses an ink box capable of automatically supplying liquid and discharging waste liquid, and the structure of the ink box comprises a liquid conveying pipe, an external ink box, a maintenance cover, pressure extraction vent holes, observation windows, internal ink boxes, an internal liquid conveying connector. The number of the internal ink boxes is two, and the top ends are connected with the internal liquid conveying connector in a locked manner. The internal liquid conveying connector is glued to one end of the liquid conveying pipe, and the right end of the external ink box is connected with the maintenance cover in an inset and bucked manner. The front side of the bottom end is connected with the other end of the liquid conveying pipe in an inset and glued manner. The top of the maintenance cover is provided with four pressure extraction vent holes in an integrated manner from the front to the back, and the right end is provided with four observation windows in an integrated manner from the front to the back. When a user uses the ink box, a mechanism which is formed by a spring, a clamping rod, a push rod and a draw rope of the equipment can enable the equipment to seal a liquid storage cabin of the equipment, can achieve the closed prestretching of liquid supplementation and liquid drainage, guarantees the airtightness of the equipment during the automatic supply of liquid and the discharge of waste liquid, and facilities the application.

Description

technical field [0001] The invention is an ink box capable of automatic liquid supply and waste liquid discharge, which belongs to the field of continuous liquid supply ink box. Background technique [0002] Ink cartridges mainly refer to the components used to store printing ink in inkjet printers and finally complete printing. [0003] The continuous ink supply system, referred to as continuous supply, is a new ink supply method that has only appeared in the field of inkjet printers in recent years. Continuous ink supply system, which uses an external ink bottle to connect with the ink cartridge of the printer with a conduit, so that the ink bottle continuously provides ink to the ink cartridge, which is the so-called "continuous supply". The biggest advantage of the continuous ink supply system is that it is affordable, and the price is much cheaper than the original ink. Secondly, the ink supply is large, and it is convenient to add ink. Generally, the capacity of one ...

Problems solved by technology

[0006] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an ink cartridge capable of automatically supplying liquid and discharging waste liquid, so as to solve the problem of external ink cartridges that are easily caused when the ink is added and replaced to the continuously supplied outer ink cartridges in the use of the prior art. The air bubbles in the ink cartridges cause the ink supply of the inner ink cartridges to be unable to continue after the continuous supply, causing inconvenience
