Embodiment Construction

[0024] In order to further understand the purpose, structural features and functions of the present invention, the detailed description is as follows in conjunction with the accompanying drawings.

[0025] In terms of actual use, the printable negative pressure of the ink cartridge 1 is -2 to -18 mm Hg, and the negative pressure of the negative pressure regulator is -10 mm Hg, while the negative pressure of the ink cartridge 1 is During the process from removing the printer to turning it upside down, the following briefly describes the conditions for maintaining the liquid-air interface. When the ink cartridge 1 is just removed from the printer as shown in Figure 1 (A), the pressure at point A is atmospheric pressure. That is to say, it is 760 mm Hg, the pressure at point B is (760-12) mm Hg, the pressure at point C (close to the liquid-gas interface) is (760-10) mm Hg, and the pressure at point D is (760- 10.2) mmHg.

[0026] And the ink cartridge 1 shown in Fig. 1 (B) has j...

Abstract

A negative pressure regulator forms reinflation hole on ink box and has neck opening with section area being less than section area of rest parts so that ink can be filled in reinflation hole by utilizing capillary force for being used as liquid-air interface to prevent ink box from improper invasion of outside air.

Description

technical field [0001] The invention relates to a negative pressure regulator, which is used in ink cartridges of inkjet printers to maintain proper negative pressure inside the ink cartridges. Background technique [0002] Inkjet printers are already a fairly reliable and efficient printing tool. Typically, an inkjet printer has an inkjet printhead that traverses relative to the surface on which it is printed and ejects ink droplets. A control system moves the inkjet print head to the appropriate position and then causes it to eject ink droplets, which land on the printing surface to form the desired image or data content. An ink pen (ink pen) is usually used in this type of printer, which mainly includes two parts such as an ink cartridge for storing and supplying ink and an inkjet print head. [0003] The inkjet print head is usually provided with a plurality of orifices, and each orifice has an ink chamber connected thereto. In operation...
