Description

Ink-cases of printers

Technical field

The utility model relates to employed accessory on the ink-jet printer, relates in particular to a kind of ink-cases of printers.

Background technology

Existing similar ink-cases of printers adopts water tumbler formula structure more or utilizes sponge to realize storage China ink and ink supply function.Since sponge exclusive capillarity, can adsorb a part of ink when last printing to, cause waste.Such print cartridge adopts modes such as convincing air drain in perforate on the cover or at ink outlet port by patient analysis to guarantee air pressure balance in the print cartridge and ink supply smoothness in the print procedure, but is difficult to avoid in print procedure and prints the ink leak phenomenon that occurs when finishing.And adopt the seal buckle mode to seal, can cause bigger waste.

Summary of the invention

The purpose of this utility model is: a kind of ink-cases of printers is provided, and it can not only prevent in print procedure and print the ink leak phenomenon that occurs when finishing, and can reduce remaining ink to greatest extent.

The utility model is achieved in that a kind of ink-cases of printers comprises end box, cover, is positioned at filter tip, photosensitive device on the end box diapire, is installed in the detachable handle on the end box, pouring ink hole is arranged on the cover, its special character in: also comprise the check valve gas operated device; Described filter tip is one to have the cylindrical shell of upper and lower opening and end box one, the kapok core is arranged in the cavity of filter tip, have one to run through the dividing plate of the whole width of end box and the sidewall of end box is connected into one, dividing plate and end box diapire, filter tip are gapped, upper fixed in the upper shed of dividing plate upper surface, filter tip has a decompression film, and is gapped between decompression film and the filter tip upper shed; Gap between dividing plate and end box diapire, the filter tip, the gap between decompression film and the filter tip upper shed constitutes ink channel, and is relative with light-sensitive surface, and the end box diapire adjacent with filter tip, and having lifted up in end box with horizontal plane has certain angle.

Its special character in: institute's check valve gas operated device comprises valve seat, spool, back-moving spring, the valve gap with the cover one, the venthole that have an air admission hole on the valve seat, communicates with the box body inner chamber, overlap back-moving spring on the valve rod of spool, the other end of back-moving spring is arranged in the shrinkage pool of valve gap.

Its special character in: described photosensitive device is the light-sensitive surface that is positioned at the cover inwall, and light-sensitive surface cooperates with the printer optical sensor.

Its special character in: the bottom of pouring ink hole inner chamber is cylinder and inverted cone stage body shape, the sealing of a steel ball and rounding taper type inner chamber fluid,matching.

The utility model ink-cases of printers, have one with the cover one and with extraneous, end box in the check valve that communicates, but end box, cover constitute the container of a storage ink; Gapped between dividing plate and end box diapire, the filter tip, the gap of sealing between film and the filter tip upper shed constitutes ink channel, seal the air guide film in the exit of nozzle, can not only prevent in print procedure and print the ink leak phenomenon that occurs when finishing, and can reduce remaining ink to greatest extent.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of ink-cases of printers comprises end box 7, cover 9, be positioned at filter tip 10 on end box 7 diapires, be installed in the handle 6 on the end box 7, pouring ink hole 11 is arranged on the cover 9, the bottom of pouring ink hole 11 inner chambers is cylinder 1101 and rounding frustum 1102 shapes, a steel ball 5 and the sealing of rounding frustum 1102 shape inner chamber fluid,matchings.

Described filter tip 10 is one to have the cylindrical shell of upper and lower opening and end box one, kapok core 8 is arranged in the cavity of filter tip 10, the under shed of filter tip 10 is that the ink outlet port place is by sealing 2 sealings of air guide film, during use, sealing air guide film 2 removes, there are a dividing plate 13 that runs through end box 7 whole width and the sidewall of end box 7 to be connected into one, dividing plate 13 and end box 7 diapires, filter tip 10 are gapped, upper fixed in the upper shed of dividing plate 13 upper surfaces, filter tip 10 has a decompression film 1, and is gapped between decompression film 1 and filter tip 10 upper sheds; Gap between dividing plate 13 and end box 7 diapires, the filter tip 7, gap between decompression film 1 and the filter tip upper shed constitutes ink channel 14, relative with light-sensitive surface 4, and end box 7 diapires 15 adjacent with filter tip 10, having lifted up in end box 7 with horizontal plane has certain angle, and the angle of diapire 15 and horizontal plane can be 10 °, 15 °, 20 ° etc.

Constitute check valve gas operated device 12 with valve seat 1201, spool 1202, back-moving spring 1203, the valve gap 1204 of cover 9 one, the venthole 1206 that has an air admission hole 1205 on the valve seat 1201, is on good terms with the box body inner chamber, cover back-moving spring 1203 on the valve rod 12021 of spool 1202, the other end of back-moving spring 1203 is arranged in the shrinkage pool 12041 of valve gap 1204; Inwall at cover 9 has light-sensitive surface 4, and light-sensitive surface 4 is as photosensitive device, and light-sensitive surface 4 cooperates with printer optical sensor (not shown); Check valve gas operated device 12 also can adopt other shape.

The utility model operation principle is as follows: because print cartridge 9 itself has negative pressure, tear when sealing air guide film 2, under the external atmosphere pressure effect, check valve gas operated device 12 is opened, and atmospheric pressure continues ink is pressed onto filter tip 10 ink outlet port places.This moment, print cartridge 7 inside and outside pressure kept balance, and check valve gas operated device 12 is closed.Seal after air guide film 2 continues to tear, ink accumulates in the ink outlet port place.The initial print stage, ink flows to printhead under the printhead suction, cause print cartridge 7 cavity pressures less than print cartridge 7 chamber external pressures, because the existence of pressure differential, print cartridge 7 chamber outer air are backed down check valve gas operated device 12, the air push ink toward print head that constantly flows to; When printing stopped, printhead stopped suction, and air stops to flow, and check valve gas operated device 12 resets, and pressure restores balance, and ink also stops to flow.So circulation; when continuous printing acquired a certain degree the decline of ink position, when the Jimo water level dropped to print cartridge 7 bottoms, the light-sensitive surface 4 on the cover 9 started working the printer optical sensor according to refraction principle; printer starts the printhead defence program, and computer shows that China ink to the greatest extent.
