Description

Ink-jet printer cartridge

Technical field

The utility model relates to ink-jet printer cartridge.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 complementary with 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 subjected to the print signal control by 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.

No matter be the piezoelectric ink jet printer, or bubble type ink-jet printer, the ink tank that is complementary with it only has limited volume, after ink in ink tank exhausts, for keeping the sustainability of print job, usually the measure of taking is exactly the print cartridge that more renews, and empty cartridge often is used as rubbish and abandons.This not only causes the destruction to environmental resource, also is unfavorable for reducing client's job costs.Referring to Fig. 1～3, show the structure of the ink-jet printer cartridge of the less and difficult recycling of a kind of existing ink capacity.This print cartridge 100 mainly is made of the regulating and controlling mechanism that shell 101, Soft Roll 102, pedestal 103 and regulation and control ink flow.The mobile regulating and controlling mechanism of ink comprises check valve 104, pump 105, pump spring 106, spool 107 and goes out black spring 108.Shell 101 is that it has an opening 109 according to a housing of the mode of appearance design of Soft Roll 102.By opening 109, the main part of Soft Roll 102 can be held in the inner chamber of shell 101 into, and so shell 101 can provide suitable support and protection to Soft Roll 102, also helps sight.Soft Roll 102 is by extending framework 111 on support 110, and coats the closed containers that mantle 112 backs form on framework 111, and its internal cavities promptly is the place that holds ink.On support 110, be provided with corresponding ink flow passage 113.Ink flow passage 113 promptly constitutes airtight Mo Lu system fully after support 110 is with pedestal 103 combinations, this Mo Lu system along ink flow passage 113, is communicated to the inking mouth of offering 115 via the ink outlet port 114 that is opened on the support 110 on pedestal 103.Insert at print cartridge 100 under the state of ink-jet printer word car, the ink that flows out from inking mouth 115 is transported to the record head top nozzle.Aforementioned check valve 104 is laid in the ink outlet port 114, is used for controlling the flow direction of ink.Pump 105 and pump spring 106 are set in the ink flow passage 113, are used for extracting the ink that holds in the Soft Roll 102.Spool 107 and go out black spring 108 and be arranged in the inking mouth 115, they regulate the quantity of ink that flows out via inking mouth 115 in real time according to the ink consumption of record head nozzle.

Summary of the invention

Exhaust the problem that back print cartridge empty van body can not utilize once more at above-mentioned ink, the utility model purpose is to provide a kind of ink-jet printer cartridge that can replenish ink.

According to the ink-jet printer cartridge of above-mentioned the utility model purpose design, comprise shell, Soft Roll, pedestal, the mobile regulating and controlling mechanism of ink and supply cartridge.Shell is coated on the Soft Roll periphery.The mobile regulating and controlling mechanism of ink comprises check valve, pump, pump spring, spool and goes out black spring.Between Soft Roll and pedestal, be provided with the ink flow passage.Check valve is laid in the port of ink flow passage near Soft Roll.Pump and pump spring are arranged in the ink flow passage.Spool and go out black spring and be arranged in the port of ink flow passage near pedestal.Supply cartridge has at least one pipeline that passes shell and be communicated with the Soft Roll inner chamber.

Aforementioned ink-jet printer cartridge, its supply cartridge has the opening that is communicated with external environment condition along the top of vertical.This opening is sealed movably by stopper.

Ink-jet printer cartridge of the present utility model, the drawback that is difficult to additional ink at existing ink tank volume finite sum, on the outer wall of existing print cartridge, offer the ink replenishing pipeline, through this ink replenishing pipeline print cartridge and ink feed box are connected as one, but and the state of maintenance ink feed box supply ink.So, not only can make full use of the projected life of existing ink tank, also reduce and changed the link of print cartridge and abandon the environmental pollution that useless print cartridge is caused, and provide support for the ink-jet printer continuous operation.
