Multi-functional ink supplying device

Abstract

The invention belongs to the technical field of printing equipment, and particularly relates to a multi-functional ink supplying device. The multi-functional ink supplying device comprises an ink cartridge body and a housing, wherein an ink outlet is formed in the bottom of the ink cartridge body; an air guiding hole is formed in the top of the ink cartridge body; and an ink accommodating cavity is formed in the ink cartridge body. The multi-functional ink supplying device is characterized in that a first liquid level sensor is arranged in the ink accommodating cavity; an ink storing box is arranged on one side of the ink cartridge body; the ink cartridge body is fixedly connected with the ink storing box, and a check valve is arranged at a connector of the ink cartridge body and the ink storing box; a second liquid level sensor is arranged in the cavity of the ink storing box; a pipeline pump is arranged in the ink storing box, and is connected with the check valve through a pipeline; a controller is arranged on the ink storing box; and the controller is connected with the first liquid level sensor and the second liquid level sensor. The multi-functional ink supplying device disclosed by the invention has the beneficial effects that an ink cartridge of a printer is simple, compact and reasonable in structure, so that a large amount of office space is saved; ink is convenient and fast to add; properties are stable; the production cost is low; and the multi-functional ink supplying device has wide market prospects.

Description

technical field [0001] The invention belongs to the technical field of printing equipment, and in particular relates to a multifunctional ink supply device. 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 ...

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
