Technical field
The utility model relates to cartridge of ink-jet printer.This print cartridge is with the form ink reservoir of pure cavity, be set on the ink-jet printer word car with the adaptive record head of this print cartridge, print cartridge as the ink containment device then is assemblied on the ink-jet printer word car removably, and keeps being communicated with the nozzle on the record head by ink supply pin and corresponding ink flow passage.
Background technology
The inkjet type printer, its printing type normally provides Mo Yuan by the ink tank of print cartridge and so on, via corresponding ink flow duct ink is transported to record head, under the driving of print signal with ink from the nozzle ejection that is provided with on the record head to recording mediums such as paper, finish the record of character or figure.Common commercially available ink-jet printer can be divided into piezoelectric ink jet printer and bubble type ink-jet printer according to its structure of nozzle form.
The piezoelectric ink jet printer is that near the ink flow duct both sides its record head nozzle respectively are provided with one or more piezo-electric crystal.Piezo-electric crystal is controlled by the print signal of data modulation, produces the contraction or expansion distortion, and the ink in the extruding jet nozzle penetrates the back from nozzle and forms fine liquid drops, splashes down to recording medium for example on the page of paper, forms a measuring point.
The bubble type ink-jet printer, its recording head structure is similar to the piezoelectric ink jet printer.Their difference is that the bubble type ink-jet printer is provided with heating electrode near ink flow duct inwall the record head nozzle or outer wall.The electric impulse signal of data modulation is sent on the heating electrode of nozzle, and heating electrode is rapidly heated, and near the ink of nozzle is vaporized rapidly, forms steam bubble.The pressure that the steam bubble expansion produces makes ink penetrate the back from nozzle and forms fine one by one ink droplet, splashes down to the paper page.After electric pulse disappeared, the ink in the ink devaporation, nozzle maintained level with neat mouthful of nozzle outer surface by surface tension.Record head extracts the ink flow duct at the ink flow nozzle place in the negative pressure guiding ink storage chamber that forms behind the ink.
According to the configuration relation of record head with print cartridge, ink-jet printer cartridge comprises two types again.A kind of is the integral structure print cartridge of print cartridge and record head unification; Another kind is the split-type structural print cartridge that print cartridge separates with record head.The print cartridge of integral structure had both comprised that record head also comprised the ink storeroom, and its record head is arranged on the ink outlet port of print cartridge.The print cartridge of split-type structural, its ink storeroom and record head are separated from each other setting, and the ink storeroom only is used for the splendid attire ink, and record head then is arranged on the printer word car.Wherein, the print cartridge of split-type structural comprises for example print cartridge of two kinds of forms of sponge storage China ink of pure cavity storage China ink and porous material again.
The print cartridge of split type pure cavity structure form need be provided for regulating the gas control valve of the unidirectional switching of poised state between print cartridge chamber pressure and the external environment condition usually at its air guide port, spills into the print cartridge outside to avoid ink from air guide port.This print cartridge causes the print cartridge structure comparatively complicated first because setting gas control valve, and meet with at print cartridge under the situation of upset, canting, vibration and/or temperature change, will be between inner each chamber of print cartridge owing to gas in it become bubble in small, broken bits with the ink mixing, and the phenomenon of gas irregular migration between each chamber appears.In a single day these bubbles enter the print cartridge ink outlet port, just might move about to the nozzle of record head along ink-jet printer ink supply pin, so that form record writing broken string, inkless etc.
Referring to Fig. 1 a, 1b and 2a, 2b two kinds of black cavity configurations that have print cartridge now are shown.Wherein, black chamber that Fig. 1 a, b represent 12 directly sets out second through holes 7 that are used to transport ink on the wall of chamber, 12 in the black chamber that Fig. 2 a, b represent enters black chamber 12 to ink by one section guiding tube 22 after one of the chamber wall in black chamber 12 guides near its relative chamber wall.No matter be second through hole of on ink cavity wall, directly offering 7 shown in Figure 1, still shown in Figure 2 by the guiding tube 22 of its port near the chamber wall in black chamber 12, the bubble 23 that two kinds of black cavity configurations retain in irritating black process all may be when upset situations such as (shown in Fig. 1 b, 2b) appears in print cartridge, holds black member generation gas-liquid exchange by corresponding second through hole 7 and guiding tube 22 with other of print cartridge respectively and flows into the ink outlet port that docks with ink-jet printer.
The utility model content
The utility model purpose is to provide a kind of cartridge of ink-jet printer, and this print cartridge is simple in structure, and can prevent that in the situation that upset, canting, vibration or variations in temperature appear in print cartridge the gas in ink storage chamber and/or the cushion chamber from flowing in the ink outlet port with ink.
Cartridge of ink-jet printer according to the above-mentioned purpose design comprises ink outlet port, air guide port, cushion chamber and ink storage chamber at least.Air guide port is communicated with ink storage chamber and outside atmosphere.Ink outlet port is communicated with cushion chamber.Be provided with the Mo Zhu that leads that is communicated with cushion chamber and ink storage chamber in the cushion chamber.This leads about geometric center that position that Mo Zhu is positioned at the openend of cushion chamber is in cushion chamber.
