Abstract
The utility model provides an inkjet printer ink cartridge, which comprises an ink containing chamber, an ink outlet, an air guiding channel and an air guiding opening. The ink containing chamber is used for directly containing ink, the ink outlet is used for leading the ink inside the ink containing chamber into an inkjet recording head, the air guiding channel is used for connecting the air guiding opening with the ink containing chamber, and the air guiding opening leads external air into the ink containing chamber via the air guiding channel according to supply of the ink in the inkjet recording head. At least one section in the air guiding channel is expanded into an air guiding chamber, at lease one porous foam block is filled inside the air guiding chamber, and liquid with a certain volume is absorbed inside the porous foam block. The ink cartridge has the advantages of simple structure, low cost, maintaining of proper negative pressure of the ink and stable and reliable working state.
Description
Technical field
The utility model relates to a kind of inkjet printing machine equipment, in particular, relates to a kind of ink-jet printer cartridge.
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 with ink transport 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 type nozzle printer and bubble type ink-jet printer according to its structure of nozzle form.
No matter be the piezoelectric ink jet printer, or bubble type ink-jet printer, ink tank that is complementary with it or print cartridge all need to consider following problem, the ink accommodating chamber that is print cartridge should be in opening when print out task is arranged, with in time to the nozzle of ink-jet printer supply ink, and when no print out task, be in closed condition, in time to nip off the mobile of ink and to prevent the ink outflow.The print cartridge that existing ink-jet printer uses, more is that portion uses check valve to realize the control of the flow regime of aforementioned ink within it.
The print cartridge check valve is many by seal member and elastomeric element, and for example spring is formed, or directly adopts the material with elastic characteristic, and for example rubber is made.The use of elastomeric element or elastomeric material, in the time of can guaranteeing that all pressure difference between print cartridge and record head is less than a certain predetermined value, the elastic force that can rely on self elasticity of material to be produced forces check valve to be in closed condition; And when the pressure difference between print cartridge and the record head surpasses a certain predetermined value, can rely on the elastic deformation of material self again, force check valve to be in open mode.
In view of the print cartridge check valve the opening/closing performance that must have, require the spring of its part or continuous variation that rubber must be able to be finished because of pressure difference that reliable and stable elastic force or deformation is provided, and potential risk such as can not cooperate because of the long-term ageing of material or with the chemical reaction of ink solution and with the sealing of miscellaneous part, its elastic force that provides or deformation generation change in a big way is provided, thereby causes check valve to open or close by the setting value of expection.Far and away, check valve in response in the requirement of above-mentioned keying function, must satisfy high requirement at aspects such as material behavior, assembly technology, elastic responses in the actual use of print cartridge, and this has increased bigger cost for undoubtedly the production and the use of print cartridge.
Summary of the invention
At the problems referred to above, the utility model purpose aims to provide and a kind ofly need not to use check valve can effectively control the ink-jet printer cartridge simple in structure of ink flow regime.
The ink-jet printer cartridge that relates to according to above-mentioned utility model purpose,
Comprise the ink accommodating chamber, be used for directly holding ink;
Ink outlet port is used for the ink in the ink accommodating chamber is introduced ink jet print head;
Air guide channel and air guide port, air guide channel is used to connect air guide port and ink accommodating chamber, air guide port is introduced ink accommodating chamber with ambient atmosphere via air guide channel according to the supply of ink in ink jet print head, expand as an air guide chamber at least one section in the air guide channel, be filled with at least one porous foam piece in the air guide chamber, and be adsorbed with the liquid of a constant volume in the porous foam piece.
Aforementioned ink-jet printer cartridge, on gravity direction, the porous foam piece has a upper surface and a lower surface, ambient atmosphere is to enter the air guide chamber via first air guide channel with the position that is lower than porous foam piece upper surface, and passes the porous foam piece and arrive the ink accommodating chamber that enters into described print cartridge behind second air guide channel again with the position that is lower than porous foam piece upper surface.
Aforementioned ink-jet printer cartridge, its porous foam piece is a sponge block.
The liquid of absorption is ink in the aforementioned ink-jet printer cartridge, its porous foam piece.
Aforementioned ink-jet printer cartridge, it also comprises the ink filling port that is communicated with ink accommodating chamber and external environment condition, and ink filling port is by able to turn on or off piston closes.
Ink-jet printer cartridge of the present utility model is expanded as an air guide chamber with a section of connecting in the air guide channel of print cartridge air guide port and ink accommodating chamber, and is filled with the sponge block that is filled with ink in the air guide chamber interior.Ambient atmosphere must be passed the sponge block that has been adsorbed with ink and arrive second air guide channel after being entered the air guide chamber via first air guide channel, could further arrive the gas make-up of ink accommodating chamber so that consumption of ink in the print cartridge to be provided.Be adsorbed with the existence of the sponge block of ink in the air guide chamber, guaranteed between print cartridge ink outlet port and air guide port, to have the existence of a predetermined negative pressure value, and because sponge block has the suction-operated to ink, guaranteed the relative stability of this predetermined negative pressure value, and the size of this negative pressure value of being scheduled to is to set by the height of adjusting sponge block.By the reasonably setting of predetermined negative pressure value, thus guaranteed in the print cartridge ink not can from ink outlet port leak to outside and when the printout demand is arranged to effective ink feed of record head nozzle.
The beneficial effects of the utility model are, and are simple in structure, with low cost, and keep the stable working state of ink appropriateness negative pressure reliable.
