Problems solved by technology

[0009] The main purpose of the present invention is to provide a continuous liquid supply device with internal pressure adjustment to overcome the ink leakage in the existing continuous liquid supply system due to the negative pressure gradually disappearing due to the pressure difference between the print cartridges being disassembled and assembled many times , which leads to abnormal printing quality, and the existing manual use of ink from the external ink supply cartridge to guide the printed liquid into the print cartridge, which increases labor costs and cannot be automated.

Abstract

The invention relates to a continuous liquid supply device with internal pressure adjustment, which comprises a liquid supply container, a printing casket and a suction device, wherein the liquid supply container is used for storing liquid; the printing casket is provided with an ejection hole, and the height different exists between the printing casket and the liquid supply container; and the suction device is connected with an ink supply container and the printing casket and used for carrying out suction on the printing casket, thereby guiding the liquid into the printing casket and recovering the internal pressure of the printing casket to the initial value.

Description

Technical field [0001] The invention relates to a continuous liquid supply device, especially a continuous liquid supply device with internal pressure adjustment. Background technique [0002] Generally speaking, inkjet printers are widely welcomed by consumers due to their advantages of easy operation and printing on a variety of inkjet media. However, after using for a period of time, inkjet printers will have to be replaced due to the exhaustion of the ink cartridges. Ink cartridges, the current common replacement method is to discard the old ink cartridges and install a new ink cartridge to provide ink. This not only causes a waste of the ink cartridge body, but also invisibly increases the user’s burden due to the high price of the ink cartridge. Overhead. In order to save printing costs, avoid waste of resources and comply with environmental protection trends, a continuous ink supply system that reuses the same ink cartridge has been developed accordingly. [0003] The exis...
