Description

TECHNICAL FIELD

[0001] The present application relates to the field of printers, in particular to a preparation method of an ink supply hose for an inkjet printer. BACKGROUND

[0002] It is known that inkjet printers are the most widely used printers at present, but in actual use, the ink supply is often not smooth. Most of the currently widely used inkjet printers apply the principle of siphon. The principle of siphon is that in two containers filled with liquid and connected by a siphon tube, the liquid always flows from the container with high pressure into the container with low pressure; in the printing process, the ink cartridge of the printer continuously supplies ink to the print head; at the same time of supplying ink, the pressure in the ink cartridge is also decreasing, and the same capacity of air needs to be sucked in to maintain pressure balance; the ink supply pipeline and the print head of the continuous ink supply system are prone to be blocked. Due to the open use environment, ink volatilization, and air bubbles generated during ink replacement, the print head is blocked, if the printer is idle for too long, or in high temperature, dryness, and direct sunlight, the ink in the ink supply pipeline and the inkjet head is more prone to clumping and blocking, so that the printer cannot supply ink normally, resulting in ink breakage or lack of certain color during printing; In view of the above situation, the ink supply pipeline is blocked, so that the printer cannot work normally, therefore, it is necessary to provide a new type of ink supply pipeline to solve the above technical problems. SUMMARY
