Detailed description of the invention
With reference to Fig. 1 ~ Figure 11, a kind of nozzle structure of the present invention, specifically see Figure 11, for being communicated with a print cartridge 3, print cartridge 3 comprises a mouth of pipe 31 out of ink, nozzle structure comprises a head body 1, head body 1 is provided with dock with the mouth of pipe out of ink 31 of print cartridge 3 one on ink channel 11 and be connected the ink channel 12 of nozzle wafer, upper ink channel 11 is communicated with lower ink channel 12, ink in print cartridge 3 is incorporated in lower ink channel 12 by upper ink channel 11, nozzle wafer is shelved in the installation position 18 of head body 1 bottom face (specifically see Fig. 8), ink forms ink droplet drops through nozzle and forms printing ink marks on the print medium.Be provided with demarcation strip 13 in described upper ink channel 11, described upper ink channel 11 is divided into some ink channel by this demarcation strip 13, and the ink channel be separated to form by demarcation strip 13 is communicated with described lower ink channel 13, can flow into smoothly in lower ink channel 12 to make ink from upper ink channel 11.
In an embodiment of the present invention, the quantity of described demarcation strip 13 is preferably one, and demarcation strip 13 is by the axis of upper ink channel 11, and upper ink channel 11 is divided into the first symmetrical ink channel 111 and the second ink channel 112 by this demarcation strip 13.By the axis of demarcation strip 13 by upper ink channel 11, make the first ink channel 111 and the second ink channel 112 symmetrical, avoid the ink channel that is separated into by demarcation strip 13 small one and large one, larger ink channel can make bubble can continue accumulation, still may cause empty black phenomenon and plug phenomenon.
In practical structures, lower ink channel 12 is generally a slotted hole (specifically see Fig. 8), preferably demarcation strip 13 is arranged to the longer axis parallel of lower ink channel 12 with this.Consider the Structural assignments of ink-jet printer complete machine, upper ink channel 11 is not positioned at position directly over lower ink channel 12, but arrange along the long axis direction i.e. front and back of lower ink channel 12, overlap (specifically see Fig. 1 and Fig. 2), front and back refer to the front and back (specifically see the direction icon in the upper left corner in Fig. 1) obtained for left and right directions with the word car vibration-direction of ink-jet printer, the longer axis parallel of preferred demarcation strip 13 and lower ink channel 12, first ink channel 111 is directly communicated with (specifically see Fig. 4) with lower ink channel 12 with the second ink channel 112, relative to demarcation strip 13 not with the longer axis parallel of lower ink channel 12, demarcation strip 13 is positioned at the side of lower ink channel 12, first ink channel 111 or the second ink channel 112 can must be communicated with lower ink channel 12 by center-aisle, demarcation strip 13 is arranged to and the longer axis parallel of lower ink channel 12 that ink can be made to circulate between upper ink channel 11 and lower ink channel 12 is more smooth and easy.
As the improvement of one embodiment of the invention, described head body 1 comprises a bottom face, this bottom face is provided with the groove 14 for flexible circuit board of fitting (not illustrating), groove 14 is for flexible circuit board of fitting, nozzle wafer is electrically connected with flexible circuit board and is positioned on the bottom face of lower ink channel 12, the other end of flexible circuit board is plugged in the wire casing (not illustrating) of word car circuit board, after making mainboard type information be passed to word car circuit board, type information is sent to nozzle wafer by flexible circuit board by word car circuit board (not illustrating), ink-jet is implemented according to type information with the nozzle on Control Nozzle wafer, be electrically connected by reed linker and contact web with nozzle wafer relative to word car circuit board, use flexible circuit board electrical connection more stable, and there will not be change print cartridge 3 time ink droplet is caused the phenomenons such as word car circuit board burns on reed linker or contact web.
Specifically see Fig. 7 and Fig. 8, consider that head body 1 is for plastic shaping component, for avoiding occurring shrink trace in its appearance, the forward and backward sidewall of head body 1 respectively arranges at least one shrink groove 15, shrink groove 15 makes the thickness of head body 1 as far as possible evenly, there is shrink trace when avoiding shaping, improve the making precision of head body 1.
In the above embodiment of the present invention, nozzle structure also comprises a head cartridge 2, head body 1 can be shaped on head cartridge 2 or be set on head cartridge 2 via combination by head body 1, be set in the embodiment of head cartridge 2 in a joint manner in head body 1, specifically see Fig. 7, a left side for described head body 1, right side wall is respectively arranged a guide rail 16, one end of guide rail 16 is fixedly connected with in same head body 1, the other end of guide rail 16 is provided with back-off 17 and this back-off 17 does not abut with head body 1 and can by curved pressure, head body 1 is plastic part, guide rail 16 is shaped in head body 1, specifically see Fig. 9, the bottom of described head cartridge 2 is provided with the storage tank 21 for laying described head body 1, the two side of this storage tank 21 is respectively provided with the guide groove 22 for allowing guide rail 16 pass through, the front end of guide groove 22 is provided with a breach 23, guide rail in head body 1 16 is through after guide groove 22, and back-off 17 snaps onto on corresponding breach 23.During assembling, after guide rail 16 is aimed at guide groove 22, head body 1 being pushed into back-off 17 snaps onto on breach 23, at guide rail 16 through in the process of guide groove 22, back-off 17 abuts with the cell wall of guide groove 22 and makes the stressed curved pressure of guide rail 16, when back-off 17 arrives breach 23 position, guide rail 16 resets and makes back-off 17 be buckled in the opening's edge of breach 23.Guide groove 22 pairs of guide rails 16 play guide-localization effect, be convenient to assemble head body 1, meanwhile, when also making guide rail 16 snap onto on breach 23 through back-off 17 after guide groove 22, head body 1 is in predeterminated position, makes the upper ink channel 11 of head body 1 aim at the mouth of pipe out of ink 31 on print cartridge 3 bottom face.By head body 1 and head cartridge 2 split are arranged, when damaging appears in head body 1, only head body 1 need be pulled down and carry out changing, relative to the integrated shower nozzle of replacing and nozzle boss, greatly reduce the replacing use cost of user.
The present invention by arranging demarcation strip 13 in upper ink channel 11, upper ink channel 11 is divided into some ink channel by demarcation strip 13, each those ink channel is communicated with lower ink channel 12, when making the ink entering into ink channel 11 enter into lower ink channel 12 via some ink channel that demarcation strip 13 is separated out, bubble in ink can not continue accumulation because of the stop of demarcation strip 13, bubble is avoided to enter in lower ink channel 12, reduce the ink channel caused because of the accumulation of bubble blocked, well improve the print quality of ink-jet printer.
The above, just better embodiment of the present invention, but the present invention is not limited to above-described embodiment, as long as it reaches technique effect of the present invention with any same or similar means, all should fall within protection scope of the present invention.
