Description
Technical field
The present invention relates to digital printing device, more particularly to a kind of positive and negative pressure control system of print cartridge.
Background technology
Ink-jet printer is in print image, and the quick inswept printing paper of shower nozzle on printer is sprayed countless by nozzle
Small ink droplet, formed image in pixel.Mobility and deadweight due to ink, printer must produce sufficiently large adsorption pressure
Power maintains the ink droplet in nozzle, so that shower nozzle steady operation, above-mentioned adsorptive pressure is the negative pressure of printer.Reliable and stable
Negative pressure is extremely crucial for ink-jet printer, and the excessive fluctuation of negative pressure easily causes shower nozzle to block or disconnected ink, and negative pressure is too small
It can cause out of ink excessive again, the difficulty of increase control ink droplet, these can all have a strong impact on out figure effect.
The air that existing ink-jet printer is typically simply persistently extracted out by vavuum pump in gas circuit forms negative pressure, and passes through
Manual modulation valve regulation vacuum magnitude absorption ink.Therefore, for formed continue, stable negative pressure, it is necessary to vavuum pump continuously works,
, can be because the working characteristics of vavuum pump changes and cause the outlet dynamics negative pressure that dies down to diminish after long-term use；Regulation manually simultaneously
Valve causes vacuum magnitude to fluctuate as temperature change or cause situations such as have particle blocking exhaust to change.
The negative pressure system of existing ink-jet printer is inaccurate to vacuum cavitations, the high and low regulation of negative pressure easily occurs and is forbidden to draw
The problem of playing above-mentioned.
The content of the invention
