Problems solved by technology

[0002] In the ink supply system of the printer, the air pump is used to push the air flow from the air pressure tube into the air bag in the ink cartridge to expand it, and then push the ink into the ink storage tank of the inkjet head. An air pressure relief valve is installed between them, the air pressure relief valve can only be opened directly to relieve the pressure, and the air pressure cannot be fine-tuned

Abstract

Disclosed is an air pressure regulating device of a printer. The air pressure regulating device comprises an air pressure circulating device and an air pressure valve which is arranged in the air pressure circulating device. The air pressure regulating device further comprises a compressing piece, a regulating piece, and an elastic element, wherein the compressing piece and the air pressure circulating device are both fixed on the regulating piece, the compressing piece abuts against the elastic element to enable the elastic element to elastically abuts against the air pressure valve, and the regulating piece can move relative to the air pressure circulating device so as to drive the compressing piece to move, thereby changing the amount of compression of the elastic element.

Description

technical field [0001] The invention relates to the field of printers, in particular to an air pressure regulating device for a printer. Background technique [0002] In the ink supply system of the printer, the air pump is used to push the air flow from the air pressure tube into the air bag in the ink cartridge to expand it, and then push the ink into the ink storage tank of the inkjet head. An air pressure relief valve is installed between them, and the air pressure relief valve can only be opened directly to release the pressure, and the air pressure cannot be fine-tuned. Contents of the invention [0003] In view of the above, it is necessary to provide an air pressure regulating device for a printer that can adjust the air pressure. [0004] An air pressure adjustment device for a printer, the air pressure adjustment device includes an air pressure flow device and an air pressure valve in the air pressure flow device, the air pressure adjustment device also includes...
