Continuous ink feeding system using air pressure equilibrium

Abstract

The invention relates to a continuous ink feeder, comprising an ink container for storing ink without an ink outlet, an ink box with an ink inlet and an ink groove opposite arranged under the ink container, a hollow muffle in the ink groove with a first opening, a second opening, and a protruded part near the second opening, while the second opening flows the ink of the ink container into the ink groove, and an ink tube whose one end is communicated with the inlet outlet and another end via the ink inlet and the first opening is sheathed in the hollow muffle and supported at the protruded part, therefore, the invention uses the height difference between the protruded part and the bottom of the ink groove to control the ink output of the ink container.

Description

(1) Technical field [0001] The invention relates to a continuous ink supply system, especially a continuous ink supply system utilizing air pressure balance. (2) Background technology [0002] With the development of computer multimedia technology, the printing output device is not only for ordinary text output, but has become a device that can be used for document output or digital photo output at the same time. Among them, inkjet printers are cheap and easy to operate. Advantages, and can be printed on a variety of inkjet media such as paper, photo paper, etc., it can be said to be an economical and effective color printing output device. [0003] However, the price of ink cartridges for inkjet printers remains high. Generally, the price of black and color ink cartridges is almost the price of buying a printer, and the ink capacity of the ink cartridges is limited, about ten grams or less. When a large number of printouts are required, in order to reduce the cost of use a...

Problems solved by technology

[0005] The continuous ink supply system using the pump method mainly uses the pump to pressurize the ink from the outer ink cartridge to the ink cartridge. Although it can achieve the effect of guiding the ink, but the price of the pump is relatively expensive. , it must be matched with other devices to control the operation of the pump, which will increase the manufacturing cost, and the pump must be driven by electricity when used, so the cost of control is relatively increased, and it is difficult to use pump suction The corner of the outer ink cartridge, so the outer ink cartridge is easy to have residual ink, which indirectly causes ink waste

In addition, due to the complex structure of the pump, it must be cleaned, repaired and maintained regularly

Furthermore, once the pump fails, due to its time-consuming maintenance, the continuous ink supply system will not be able to supply ink normally during the maintenance period, which will affect the operation of the inkjet printer and its printing quality
