Problems solved by technology

[0006] The main purpose of the present invention is to provide an ink supply system to solve the problem of ink leakage caused by the drop of back pressure caused by the reduction of ink in the conventional ink supply system, which in turn leads to unstable or abnormal printing quality, and the replacement of the ink supply cartridge must be done manually And it is easy to cause damage to the ink supply cartridge or inkjet components, which consumes a lot of cost and time, and when the inkjet components are not printed, the ink dries up and cannot be recycled to cause ink waste, or even cause the ink supply system to fail.

Abstract

The invention relates to an ink supply system. The ink supply system comprises a feed liquid container, a pump, an ink storage device and a valve body. The ink storage device is provided with a first input port, an output port and a sensing element. The first input port receives ink drawn off by the pump, the output port and an ink-jet element are connected for outputting ink, the sensing element is arranged in the ink storage device for sensing the liquid height of the ink in the ink storage device so as to control the pump to run to draw off the ink, the valve body is connected between the ink storage device and the ink-jet element to selectively enable the ink to flow to the ink storage device from the ink-jet element for recovery. By such a structure, the sensing element senses the liquid height of the ink storage device so as to maintain the ink content of the ink storage device, enable the pressure in the ink storage device to be stable and accordingly maintain the pressure of the ink cavity of the ink-jet element, thus the effect of stable printing quality is achieved.

Description

technical field [0001] The invention relates to a system, especially an ink supply system applied to printing equipment. Background technique [0002] Generally speaking, among all kinds of printing devices, inkjet printers are popular among consumers due to their advantages of easy operation and the ability to print on various inkjet media. However, inkjet printers are often used in After using for a period of time, the ink cartridge will be replaced due to the exhaustion of ink in the ink cartridge. The current common replacement method is to discard the old ink cartridge and install a new ink cartridge to provide ink. This will not only cause damage to the ink cartridge body Waste, and because of the high price of the ink cartridge, the user's expense is increased invisibly. In order to save printing costs, avoid waste of resources and conform to the trend of environmental protection, a continuous ink supply system that reuses the same ink cartridge was born accordingly....
