Embodiment 1
[0037] An air pressure balance device for an ink cartridge of an inkjet printer, comprising a buffer chamber C and an ink cartridge A. An ink outlet is provided at the bottom of the ink cartridge A, and the ink outlet is sealed by a solid rubber plug B. The buffer cabin C includes a buffer cabin main body, an exhaust pipe 3 , a balance pipe 4 and an extraction pipe 5 , and the buffer cabin C main body is a closed container. One end of the balance tube 4 leads into the bottom of the inner cavity of the buffer chamber C, and the other end is integrally connected with the stainless steel fine needle tube 1 to form a connected body between the buffer chamber C and the ink cartridge A. One end of the exhaust pipe 3 communicates with the top of the inner cavity of the buffer cabin C, and the other end is provided with a normally open valve V1. The chamber pressure is in balance with the external atmospheric pressure. That is, when the normally open valve V1 is de-energized, the con...
Embodiment 2
[0041] In this embodiment, the ink cartridge A is used to contain the solvent used for cleaning the pipeline, so it is called solvent cartridge A in this embodiment. It includes a buffer cabin C and a solvent box A. A solvent outlet is provided at the bottom of the solvent box A, and the solvent outlet is sealed by a solid rubber plug B. The buffer cabin C includes a buffer cabin main body, an exhaust pipe 3 , a balance pipe 4 , an extraction pipe 5 and a solvent extraction pipe 6 , and the main body of the buffer cabin C is a closed container. One end of the balance tube 4 leads to the bottom of the inner cavity of the buffer cabin C, and the other end is integrally connected with the stainless steel fine needle tube 1 to form a connected body between the buffer cabin C and the solvent box A. One end of the exhaust pipe 3 communicates with the top of the inner cavity of the buffer cabin C, and the other end is provided with a normally open valve V1. The chamber pressure is i...
