Compared with prior art, print cartridge of the present utility model need not in the bottom of test chamber to be provided with and seals film, has simplified technology, can prevent effectively that sealing film rupture because of test chamber causes ink leak.
Further technical scheme is, is provided with dividing plate between described test chamber and the described balanced chamber, the moulding and being fastened on the inwall of this box body respectively of this dividing plate and described box body.Wherein, the described through hole that is communicated with described balanced chamber and test chamber is formed on the described dividing plate, and preferably, described through hole is positioned at the top of described dividing plate.
Further technical scheme is, the bottom of described air guide post is communicated with outside atmosphere by waterproof is continuous.
Description of drawings
Fig. 1 is the structural representation of existing a kind of print cartridge.
The structural representation of Fig. 2 a kind of print cartridge of the present utility model.
The specific embodiment
Referring to Fig. 2, the basic structure of a kind of embodiment of the utility model print cartridge and the disclosed print cartridge of CN200520062070.6 utility model patent is similar, it has comprised box body 3 and lid 2 equally, lid 2 is used for capping box body 3, the liquid injection hole 22 that it is provided with outstanding handle 21 and is used to pour into ink, this liquid injection hole 22 is sealed by plug.
Be provided with the storage China ink chamber 30 that is used to preserve black liquid in the box body 3, be used to be communicated with the black chamber 30 of storage and outside atmosphere air guide post 34, be used to test chamber 315 and the buoy 316 regulating the balanced chamber 313 of cavity pressure and be used to monitor ink storage in the chamber; buoy 316 is arranged in test chamber 315, seals film 317 in the top in balanced chamber 313 is provided with.For guaranteeing that buoy 316 floats on the ink level, its density should be less than the black liquid in the black chamber 30 of storage, and the contact area of itself and black liquid should guarantee a suitable numerical value.Be convenient monitoring, the sidewall 3151 of test chamber 315 adopts material preparation transparent or light-permeable.Under the situation of range estimation or use optical sensor, just can monitor print cartridge ink inside situation easily like this.The bottom of box body 3 is provided with the ink supply port 32 that is used for to printer ink-providing, and ink supply port 32 is cylindrical, and the bottom of ink supply port 32 is provided with the seal 322 that can be complementary with the print needle of ink-jet printer.After irritating China ink, available ink supply port seals the lower end surface of film 323 sealing ink supply ports 32.
Described test chamber 315 and the 313 adjacent settings of balanced chamber are worked in test chamber 315 in order to guarantee buoy 316, are provided with dividing plate 4 between test chamber 315 and the balanced chamber 313.This dividing plate 4 and box body 3 moulding respectively, but not it is one-body molded, that is to say that this dividing plate 4 is parts independently, She Ji purpose is after being convenient to buoy 316 put into test chamber 315 via balanced chamber 313, dividing plate 4 to be weldingly fixed on the inwall of this box body 3 again like this.The top of dividing plate 4 is formed with through hole 41, and balanced chamber 313 is communicated with by through hole 41 with test chamber 315, and this through hole 41 is positioned near the top of balanced chamber 313 and test chamber 315 simultaneously.Balanced chamber 313 is communicated with the black chamber 30 of storage in its bottom.The bottom of test chamber 315 is communicated with the black chamber 30 of storage, and the position of this connection is lower than the bottom in balanced chamber 313, being located in the same horizontal plane substantially with the bottom of storing black chamber 30 bottom of test chamber 315.So design, can consume the ink in the black chamber 30 of storage earlier, in the ink consumption of storage in the black chamber 30 to the bottom in balanced chamber 313, be that air enters before the balanced chamber 313, buoy 316 is near the top of test chamber 315 all the time, realize using to greatest extent the ink in the black chamber 30 of storage, reduce residual China ink amount.
Because buoy 316 need not to pack into from the bottom of test chamber 315, the film that seals that test chamber 315 bottoms are not provided with opening and are used to seal this opening, be formed in one between the diapire 3152 of test chamber 315 and its sidewall 3151, thereby simplified technology, can prevent effectively that sealing film rupture because of test chamber causes ink leak.
The bottom position of air guide post 34 is lower than the bottom in the black chamber 30 of storage, and its upper end exceeds the black chamber of storage 30 inner liquid levels, is communicated with the black chamber of storage 30 gaseous states.In the bottom of air guide post 34, be provided with the air guide chamber that a part of sidewall is 342 that constitute, the position is lower than storage 30 bottoms, black chamber by box body 3, waterproof silk floss 341 is clogged in the air guide chamber, adopt heat sealing film material confined bed air cavity bottom opening afterwards.This air guide chamber bottom opening also is communicated with air guide post 34, its top is communicated with outside atmosphere by being embedded in air drain 332 in box body 3 diapires and the opening 331 on box body 3 diapires, print cartridge is in the ink supply process, outside atmosphere is supplemented to print cartridge inside by the direction of arrow among the figure, to keep the inner suitable negative pressure of print cartridge.Before the print cartridge installation is used, use the same material sealing opening 331 that seals film 323 disjunctors with ink supply port.Use waterproof continuous 341 and join behind mazy air drain 332, can make the ink in the print cartridge be difficult to enter air guide chamber and corresponding air drain 332 parts, thereby, before installation, remove when ink supply port seals film 323 and can guarantee that inkless liquid spills.
Before using the utility model print cartridge, earlier print cartridge is placed subnormal ambient, irritate China ink by liquid injection hole 22, and under negative pressure state, adopt plug sealing liquid injection hole 22, make the print cartridge inner chamber keep negative pressure state.
When using the utility model print cartridge, in order to give full play to the indicative function of buoy 316, be located at the vertical top of test chamber 315, print cartridge should be tilted the side several seconds, to guarantee being full of ink fully in the test chamber 315, do not exist and there is air.After recovering normal use placement state, buoy 316 promptly rises the top that floats on test chamber 315.The inclination side is meant the bottom-up of test chamber 315 and top down state.During monitoring print cartridge ink inside capacity, the top of the test chamber 315 at buoy 316 places is set to range estimation or light sensors zone under the normal operating condition.
