Printing ink box capable of storing ink

Abstract

The invention belongs to the technical field of printing devices, and in particular relates to a printing ink box capable of storing ink. The printing ink box comprises an ink box body and a shell, wherein an ink outlet is formed in the bottom of the ink box body, an air guide hole is formed in the top of the ink box body and an ink containing cavity is formed in the ink box body. The printing ink box is characterized in that a first liquid level sensor is arranged in the ink containing cavity; an ink storage box is arranged at one side of the ink box body; the ink box body is fixedly connected with the ink storage box; a check valve is arranged at the connected part of the ink box body and the ink storage box; a second liquid level sensor is arranged in the cavity of the ink storage box; a pipeline pump is arranged in the ink storage box and connected with the check valve through a pipeline; a controller is arranged above the ink storage box and respectively connected with the first liquid level sensor and the second liquid level sensor. The printing ink box capable of storing ink of a printer has the beneficial effects of being simple, compact and reasonable in structure, saving a large amount of office space, being convenient and fast in ink filling, stable in performance and low in production cost and having wide market prospect.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, in particular to an ink box with an ink storage function. Background technique [0002] In an inkjet printer, an ink cartridge device is usually connected to the print head. When a printer performs a print job, one of the most basic requirements is that its ink cartridge unit can continuously and evenly discharge ink. At present, in the ink cartridge device of the prior art, the commonly used method for controlling the ink output is to store the ink by the capillary suction of a porous body, such as a sponge. The disadvantage of this porous body structure is that it occupies the effective space of the ink cartridge, so that the total amount of ink stored in the ink cartridge device generally does not exceed 60% to 65% of the total volume of the ink cartridge. Existing ink cartridges have a small capacity for storing ink and cannot be used repeatedly. After the ink cartridges are disc...

Problems solved by technology

The disadvantage of this porous body structure is that it occupies the effective space of the ink cartridge, so that the total amount of ink stored in the ink cartridge device generally does not exceed 60% to 65% of the total volume of the ink cartridge.

Existing ink cartridges have a small capacity for storing ink and cannot be used repeatedly. After the ink cartridges are discarded, they are difficult to recover and easily pollute the environment. At the same time, the ink concentration is uneven when the printer is working, and the printing quality is relatively poor, which shortens the service life of the ink cartridges and greatly reduces the use of the ink cartridges. reliability

Even if there is a device for supplying ink to the ink cartridge, it takes up a lot of space and is inconvenient to use. When the ink supply device is insufficient, it cannot be known in time
