Description
Technical field
The present invention relates to the accessory that a kind of ink-jet printer uses.
Background technology
Existing similar ink-cases of printers many employings cup type structure or utilize sponge to realize ink storage and ink supply function.Due to the capillarity that sponge is exclusive, a part of ink can be adsorbed when printing to last, causing waste.Such print cartridge to adopt on cover perforate or convince by patient analysis at ink outlet port the modes such as air drain to ensure air pressure balance in print procedure in print cartridge and ink supply smooth, be but difficult to the ink leak phenomenon avoiding occurring in print procedure and at the end of printing.And adopt seal buckle mode to seal, larger waste can be caused.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present invention is to provide the accessory that a kind of ink-jet printer of practicality uses, the ink leak phenomenon occurred in print procedure and at the end of printing can not only be prevented, and remaining ink can be reduced to greatest extent.
For reaching above-described object, the accessory that a kind of ink-jet printer of the present invention uses takes following technical scheme:
The accessory that a kind of ink-jet printer uses, comprise end box, cover, be positioned at the filter tip on end box diapire, photosensitive device, be arranged on the detachable handle on end box, check valve gas operated device, it is characterized in that, described cover there is pouring ink hole, filter tip be one have on, the cylindrical shell of under shed and end box one, kapok core is had in the cavity of filter tip, the sidewall of the dividing plate and end box that have one to run through the whole width of end box is connected into one, dividing plate and end box diapire, filter tip has gap, in dividing plate upper surface, the top of the upper shed of filter tip is fixed with a decompression film, gap is had between decompression film and filter tip upper shed, dividing plate and end box diapire, gap between filter tip, gap between decompression film and filter tip upper shed forms ink channel, relative with light-sensitive surface, and the end box diapire adjacent with filter tip, lift up in end box and had certain angle with horizontal plane, check valve gas operated device comprises the valve seat with cover one, spool, back-moving spring, valve gap, valve seat has an air admission hole, the venthole communicated with box body inner chamber, the valve rod of spool overlaps back-moving spring, the other end of back-moving spring is arranged in the shrinkage pool of valve gap, photosensitive device is the light-sensitive surface being positioned at cover inwall, light-sensitive surface coordinates with printer optical sensor, the bottom of pouring ink hole inner chamber is cylinder and inverted cone stage body shape, one steel ball and rounding taper type inner chamber fluid,matching seal.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
The present invention have one with cover one and with the check valve that communicates in extraneous, end box, end box, cover form one can the container of storage ink; Gap is had between dividing plate and end box diapire, filter tip, gap between sealed membrane and filter tip upper shed forms ink channel, sealing air-guiding film is had in the exit of nozzle, the ink leak phenomenon occurred in print procedure and at the end of printing can not only be prevented, and remaining ink can be reduced to greatest extent.

Detailed description of the invention
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the accessory that a kind of ink-jet printer of the present invention uses, comprise end box 7, cover 9, the filter tip 10 be positioned on end box 7 diapire, the handle 6 be arranged on end box 7, cover 9 there is pouring ink hole 11, the bottom of pouring ink hole 11 inner chamber is cylinder 1101 and rounding frustum 1102 shape, and a steel ball 5 seals with rounding frustum 1102 shape inner chamber fluid,matching.
Described filter tip 10 is a cylindrical shell with upper and lower opening and end box one, kapok core 8 is had in the cavity of filter tip 10, the under shed of filter tip 10 and ink outlet port place close by sealing air-guiding film 2, during use, sealing air-guiding film 2 is removed, a dividing plate 13 running through the whole width of end box 7 is had to be connected into one with the sidewall of end box 7, dividing plate 13 and end box 7 diapire, filter tip 10 have gap, above the upper shed of dividing plate 13 upper surface, filter tip 10, be fixed with a decompression film 1, between decompression film 1 and filter tip 10 upper shed, have gap; Gap between dividing plate 13 and end box 7 diapire, filter tip 7, gap between decompression film 1 and filter tip upper shed forms ink channel 14, relative with light-sensitive surface 4, and end box 7 diapire 15 adjacent with filter tip 10, lifted up in end box 7 and had certain angle with horizontal plane, diapire 15 and the angle of horizontal plane can be 10 ° 15 °, 20 ° etc.
Check valve gas operated device 12 is formed with cover 9 valve seat 1201 integrally, spool 1202, back-moving spring 1203, valve gap 1204, the venthole 1206 valve seat 1201 having an air admission hole 1205, be on good terms with box body inner chamber, the valve rod 12021 of spool 1202 overlaps back-moving spring 1203, and the other end of back-moving spring 1203 is arranged in the shrinkage pool 12041 of valve gap 1204; Have light-sensitive surface 4 at the inwall of cover 9, light-sensitive surface 4 is as photosensitive device, and light-sensitive surface 4 coordinates with printer optical sensor (not shown); Check valve gas operated device 12 also can adopt other shape.
Operation principle of the present invention is as follows: because print cartridge 9 itself has negative pressure, and when tearing sealing air-guiding film 2, under external atmosphere pressure effect, check valve gas operated device 12 is opened, and atmospheric pressure continues ink to be pressed onto filter tip 10 ink outlet port place.Pressure now inside and outside print cartridge 7 keeps balance, and check valve gas operated device 12 is closed.After sealing air-guiding film 2 continues to tear Jian, ink accumulates in ink outlet port place.The initial print stage, ink flows to printhead under printhead suction, causes print cartridge 7 cavity pressure to be less than print cartridge 7 chamber external pressure, due to the existence of pressure differential, print cartridge 7 chamber outer air backs down check valve gas operated device 12, and the air push ink constantly flow to flows to printhead; When printing stopping, printhead stops suction, and air stops flowing, and check valve gas operated device 12 resets, and pressure recover balance, ink also stops flowing.Circulation like this; when printing makes black water level decreasing acquire a certain degree continuously, when Jimo water level decreasing is to print cartridge 7 bottom, the light-sensitive surface 4 on cover 9 makes printer optical sensor start working according to refraction principle; printer starts printhead defence program, and computer display ink to the greatest extent.
