Abstract
The utility model relates to an ink box used in an ink-jet printer, which comprises an ink storage cavity used for storing ink, an ink outlet supplying ink to a printing head of the printer, an air inlet channel used for replenishing the consumed ink space with air due to printing and an air inlet. The air inlet channel is communicated with the air inlet; the air inlet is arranged at the ink outlet and communicated with the ink outlet on which a sealing film is arranged. Because the air inlet is arranged at the ink outlet and communicated with the ink outlet on which the sealing film is arranged, air passes through the gap at the matching position of the sealing film with an ink needle to be communicated with the air inlet when the ink needle punctures the sealing film, so that the air enters the ink box cavity body to replenish the space of the consumed ink due to printing to maintain the balance pressure in the ink box cavity body and guarantee the normal printing of the ink box, meanwhile, the parts of a valve, a valve seat and the like are reduced, production processes are greatly reduced, and the production cost is lowered.
Description
Technical field
The utility model relates to the equipment of printer, is specifically related to be used for the print cartridge of ink-jet printer.
Background technology
The existing print cartridge that is used for ink-jet printer, its primary structure comprise the ink storage chamber that is used to store ink, to ink outlet port, an atmosphere inlet part of the printhead ink supply of printer.In order to guarantee that print cartridge can print normally, must be in print procedure by the atmosphere inlet part constantly to the ink space make-up gas that consumes because of printing, the weighing apparatus that keep in the print cartridge cavity is pressed, and guarantees that print cartridge can normally print.Described atmosphere inlet part generally by the following technical solutions, as shown in Figure 1, the atmosphere import partly is made up of air guide film a, gas port b, its operation principle is: need first air guide film on the box body is torn when changing print cartridge, and then the printer of packing into.The effect of tearing the air guide film is to make atmosphere and the conducting of print cartridge inside cavity, and atmosphere just can enter the print cartridge cavity by gas port like this, replenishes the ink space that consumes because of printing, and the weighing apparatus of keeping in the print cartridge cavity is pressed, and the assurance print cartridge can normally be printed.The air guide film can be the sealing gasket of silica gel and so on also, need remove seal earlier equally during use, allows gas port open earlier, the printer of again print cartridge being packed into.But this scheme needs increase points for attention to the user in addition, just requires the user before using print cartridge, must be earlier air guide film or other object that be used for seal gas port of retaining on gas port be removed, and has increased user's use difficulty like this.Take the object of retaining on gas port off if the user forgets, the printer of just print cartridge being packed into may cause the ink in the printhead is drawn back into print cartridge, damages printhead.For overcoming the deficiency of above-mentioned technology, some producer has adopted scheme as shown in Figure 2, be that the atmosphere import partly is made of the valve c and the valve seat d that are installed on the cartridge case, its operation principle is: when print cartridge is packed printer into, the pressing device e contact valve of printer also makes valve separate with valve seat, atmosphere just can enter the print cartridge cavity by the space between valve and the valve seat like this, replenish the ink space that consumes because of printing, the weighing apparatus of keeping in the print cartridge cavity is pressed, the assurance print cartridge can normally be printed, but this scheme needs valve and valve seat to be used, and valve need be made of special material, to guarantee and valve base sealing, has increased the spare and accessory parts of print cartridge like this, increase production technology, more increased manufacturing cost.
The utility model content
The utility model provides a kind of print cartridge that is used for ink-jet printer, must remove the technical problem that air guide film defective on the gas port causes increasing production technology and manufacturing cost to solve the existing print cartridge that is used for ink-jet printer earlier because of overcoming the user before the use print cartridge.
In order to solve above technical problem, the technical scheme that the utility model is taked is:
A kind of print cartridge that is used for ink-jet printer, comprise the ink storage chamber that is used to store ink, to the ink outlet port of the printhead ink supply of printer, be used to make the inlet channel and the air inlet in the ink space that gas make-up consumes because of printing, inlet channel and air inlet communicate, it is characterized in that, described air inlet is arranged at ink outlet port and communicates with ink outlet port, and described ink outlet port is provided with and seals film.
Be provided with sealing ring in the described ink outlet port, the sealing end of described sealing ring is provided with groove, and described air inlet is arranged on the sidewall of groove.
The position that corresponding ink supply pin inserts in the groove of described sealing ring also is provided with a finedraw.
Also be provided with a plurality of standby air inlets on the sidewall of described o-ring groove.
After having adopted technique scheme, because air inlet is arranged at ink outlet port and communicates with ink outlet port, ink outlet port is provided with and seals film.When ink supply acupuncture is broken when sealing film, atmosphere communicates with air inlet by the gap of sealing film and ink supply pin cooperation place, atmosphere just can enter the print cartridge cavity like this, replenish the ink space that consumes because of printing, the weighing apparatus of keeping in the print cartridge cavity is pressed, the assurance print cartridge can normally be printed, parts such as valve and valve seat have been reduced simultaneously, significantly reduced production technology, reduced production cost, solved the existing print cartridge that is used for ink-jet printer and before the use print cartridge, must remove the technical problem that air guide film defective on the gas port causes increasing production technology and manufacturing cost earlier because of overcoming the user.In addition, owing to be provided with sealing ring in the ink outlet port, the sealing end of sealing ring is provided with groove, air inlet is arranged on the sidewall of groove, also be provided with a plurality of standby air inlets on the sidewall of o-ring groove, the sealing ring position also has a plurality of standby air inlets to communicate with inlet channel when adjusting to other position, reduced the assembly precision of sealing ring.
