Description

Print cartridge

Technical field

The utility model relates to inkjet printing and uses print cartridge, particularly has the print cartridge of luminous component.

Background technology

Ink-jet printer is a kind of printer commonly used at present; Its printing type normally provides Mo Yuan by the ink apparatus of print cartridge and so on; Via corresponding ink flow duct with ink transport to printhead; Under the driving of print signal with ink from the nozzle ejection that is provided with on the record head to print media such as paper, accomplish the record of character or figure.

Publication number is that the application for a patent for invention of CN101549586A discloses a kind of print cartridge.The bottom surface of this print cartridge has ink supply port, and first side has handle, has first locking member on the handle, and second side is provided with second locking member near the position of bottom.When print cartridge was installed in ink-jet printer, above-mentioned first locking member and second locking member were fixed on print cartridge in the word car of ink-jet printer.Have the transition face of an inclination between the bottom surface of print cartridge and first side, a chip is fixed on this transition face.The front of this chip has electric contact, and the back side has luminous component, and this luminous component is LED normally.When print cartridge is in place; Corresponding electric contact forms and is electrically connected on electric contact on the chip and the printer word car; LED can launch light, and the extension of aforementioned handle above LED is formed for transmitting the guiding portion of LED emission light, forms the light display part in handle end; The light of LED emission is received by the optical sensor on the printer through aforementioned lights leader and light display part, thereby makes the installment state of ink-jet printer identification print cartridge and the information of ink surplus.Although this print cartridge has print cartridge detection and localization function and ink surplus measuring ability preferably, the structure more complicated of this print cartridge, manufacturing cost is higher.

Granted publication number discloses a kind of improved print cartridge for CN201026704Y number utility model patent.This print cartridge have with aforementioned print cartridge in structure ink outlet port, handle, first locking member, second locking member, transition face and the luminescence chip identical with the position, print cartridge first side top is provided with prism, the inclined-plane of prism is facing to the optical sensor on the ink-jet printer.The light of LED emission can arrive the optical sensor of ink-jet printer through the reflection of prism, and need not to assign to realize through guiding portion and light display part are set on the handle.This print cartridge simple in structure, cheap for manufacturing cost.Yet; Still there is following defective in this print cartridge: behind the print cartridge installation in position, the light of the LED emission on the chip is scattered light, and the light that therefore incides prism is less; And incident ray is through behind the prismatic reflection; Its intensity further weakens, thus the light that causes reflecting can not be discerned by the optical sensor of ink-jet printer, ink-jet printer also just can't operate as normal.Therefore, provide a kind of print cartridge of new construction real for necessary.

Summary of the invention

The main purpose of the utility model provides a kind of print cartridge of new construction, and this print cartridge can make the light-ray condensing of luminous component emission, thereby improves the reliability of print cartridge work.

Be to realize above-mentioned purpose, the print cartridge that the utility model provides comprises box body, and said box body has the front, the back relative, first side with the front, with the first side second side surface opposite, end face and with the end face opposed bottom surface; Ink outlet port, said ink outlet port is arranged at said bottom surface; Handle, said handle comprise the base portion that is connected with first side and along the extension that extends away from first side surface direction, said extension is provided with first locking member; Chip, said chip are installed on the transition face that forms between first side and the bottom surface, and said chip front side is provided with electric contact, and the back side is provided with luminous component; Light-reflecting components, said light-reflecting components is arranged on the top of first side, and is positioned on the light path of said luminous component; Collector lens, said collector lens is positioned on the light path of said luminous component, and is arranged between said luminous component and the said light-reflecting components.

The print cartridge of the utility model; Collector lens is positioned on the light path of luminous component; And be arranged between luminous component and the light-reflecting components; The light of luminous component emission passes through the refraction of collector lens and produces gathering, and the light intensity that incides light-reflecting components like this increases greatly, thereby has improved the reliability of printer optical sensor work.

Further, the collector lens of the utility model print cartridge is convex lens.Convex lens simple in structure, with low cost, spotlight effect is good.

The specific embodiment

Referring to Fig. 1 to Fig. 3, print cartridge comprises box body 1, and this box body 1 has front 11, the back relative (invisible among Fig. 1), first side 12 with the front, with first side, 12 second side surface opposite 13, end face 14 and with end face 14 opposed bottom surface 15.Porous material parts (invisible among the figure) are installed in the print cartridge 1, and it is used to accommodate ink.First side 12 of print cartridge 1 is provided with handle 51, and handle 51 comprises the base portion 511 that is connected with first side 12 and along the extension 512 that extends away from first side surface direction, extension 512 is provided with first locking member 513.Second side 13 is provided with second locking member 131 near the position of bottom.First locking member 513 and second locking member 131 are used for the location of print cartridge when ink-jet printer is installed.The bottom surface 15 of print cartridge 1 is provided with ink outlet port 21, and this ink outlet port 21 is used for to the ink-jet printer ink supply.16, one chips 31 of transition face that are provided with an inclination between the print cartridge bottom surface 15 and first side 12 are installed on the transition face 16.Chip 31 fronts are provided with electric contact (omitting among the figure), and the back side is provided with luminous component 312.After in print cartridge is mounted to ink-jet printer, chip 31 positive electric contacts can form with the electric contact on the printer relevant position and be electrically connected, and this moment, the luminous component 312 at chip 31 back sides will be luminous.One collector lens 52 is installed on the base portion 511 of handle 51, and collector lens 52 is positioned on the light path of luminous component 312.And 12 tops, first side are equipped with a light-reflecting components 41, and light-reflecting components 41 is positioned on the light path of luminous component 312 equally, and collector lens 52 is set between luminous component 312 and the light-reflecting components 41.So; After luminous component 312 emits beam; Through the aggtegation of collector lens 52, the reflecting surface that incides light-reflecting components 41 that light is vertical, and the emergent ray of formation level; The emergent ray of this level is received by the optical receiver on the ink-jet printer, carries out follow-up print job thereby drive ink-jet printer.

In the above-described embodiments, light-reflecting components 41 is the common planar mirror, and the angle of inclination of itself and horizontal plane is 45 degree.Collector lens 52 is convex lens, and luminous component 41 is positioned on the focus of convex lens when installing.But the light-reflecting components 41 of the utility model is not limited to level crossing, and other parts with light reflection function such as prism all can.The collector lens 52 of the utility model also is not limited to convex lens, also can be the combination of concave-convex lens, perhaps other similar parts with optically focused and printing opacity effect.
