Definitions

a cartridge according to the preamble of claim 1 is known from EP-A-560 729. It has an opening on an end wall of a housing, into which a nozzle of a printhead can be inserted in a sealing manner. The end of the nozzle is closed off by a sieve, which compresses a foam body soaked with ink when it is inserted, so that ink is pressed into the nozzle.
EP-A-560 729 additionally suggests installing an additional pump in the housing.
this pump makes the ink cartridge more expensive.
FIG. 1 shows a cross section through a printhead 1 with an exchangeable ink cartridge 2.
the print head 1 has a nozzle plate with a plurality of narrow nozzles 3, each of which is assigned a thermoelectric heating element and which are connected to a tubular nozzle 5 via channels 4.
the nozzle 5 is closed at the top by a sieve 6. If a heating element is heated at the moment, a gas bubble forms, and the excess pressure ejects a droplet of ink from the nozzle in question. After the gas bubble has collapsed, ink is drawn in from the nozzle 5 by the surface tension at the nozzle mouth. This mode of operation of the print head is known.
the cartridge 2 is inserted into a rectangular tubular extension 7 of the print head 1 and secured with cooperating locking elements 8, 9.
the cartridge 2 consists of a housing 15 and a cover 16.
the bottom 17 of the housing 15 has a stepped bore 18 into which an elastomeric sealing plug 19 with a tubular wall 20 and a cover 21 connected in one piece is inserted.
the cover 21 has predetermined breaking notches 22, which are star-shaped in the example shown.
a further, small cavity 27 is formed, which is ventilated through a ventilation opening.
the ventilation opening is formed by a capillary gap between a relatively long bore 28 of the housing 15, into which a mandrel 29 of the cover 16, which is slightly smaller in diameter, is inserted.
the cartridge 2 is closed by the cover 21 at the start of insertion into the head 1 and the cover 21 is only broken through by the connector 5 after the wall 20 of the sealing plug 19 has sealed off from the connector 5, this results in a simple and safe Handling. No opening needs to be cleared before inserting the cartridge 2 (eg by removing a sealing film). A drop from an opening is therefore not possible.
the filter 25 reliably prevents any contamination of the ink from entering the nozzle 5 and thus into the narrow nozzles of the nozzle plate 3. It reduces it also the accumulation of particles on the screen 6 of the head 1, which would increase the flow resistance through the screen over time. This increases the life of the print head 1.
a precisely dimensioned, narrow, capillary air supply opening is formed in a simple manner, which would otherwise be difficult to implement by injection molding.
the narrow capillary ventilation opening largely prevents evaporation of the ink.
the sealing plug 19 can also consist of this material and can be injection molded in one piece with the housing 15.
the sealing plug 19 is sleeve-shaped and has no cover 21.
a pin 33 is inserted into it from the inside, which has a tab 34 protruding on one side from the top.
the free end 35 of the tab 34 is connected to the bottom 17 of the housing 15, for example welded.
the bore 28 is extended downwards and the mandrel 29 is integrally formed on the print head 1.
the bore 28 is closed by a thin membrane 40 which is penetrated by the mandrel 29 immediately before the latching elements 8, 9 snap into place.
the mandrel 29 has a longitudinal groove 41 at the upper end in order to ensure a connection of the capillary gap between the bore 28 and the mandrel 29 and the cavity 27.
the embodiment according to FIG. 6 has the same design as that according to FIGS. 1 or 5.
the bore 28 is closed at the lower end with an elastomeric pin 42 which, when the cartridge 2 is inserted through the front end of the mandrel 29, immediately before the latching elements 8, 9 engage the bore 28 into the cavity 27 is pushed.
the pin 42 acts as a piston when the cartridge 2 is inserted into the print head 1.
an O-ring can be attached to the upper end of the mandrel 29, which seals when the cartridge 2 is inserted against the bore 28 and projects into the cavity 27 when the cartridge is fully inserted.
the narrow, capillary gap formed by the relatively long bore 28 and the mandrel 29 used, but also the delimitation of the connector 5 from the foam body 24 by a filter 25 and a vestibule can also be used with other ink cartridges, the opening 26 of which is not covered by a cover 21 or 33 is completed, can be used sensibly with the corresponding effect.
