Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail.As it is shown in figure 1, a kind of printer head, cache, including the ink caching case 1 connect with print cartridge, inking chamber 2 that the outlet of case 1 communicates with ink and be arranged on the nozzle 3 bottom inking chamber 2.Inking chamber 2 includes the minitype piston 22 with the ink entrance 21 leading to ink inlet tube, being slidably connected in inking chamber 2, the piston controller electrically connecting minitype piston 22 with inking chamber.Nozzle 3 is included in nozzle entrance 31, the jet expansion 32 being arranged at bottom and connection nozzle entrance and the passage 33 of jet expansion that top communicates with inking chamber.Minitype piston 22 is provided for the cleaning device of cleaning nozzle outlet.
Ink caching case 1 includes for storing the caching chamber 11 of ink, ink fill port 12, insulating liquid charging port 13, ink outlet 14 and being arranged on the insulating liquid absorbed layer 15 bottom ink caching chamber.Ink fill port 12 and insulating liquid charging port 13 are respectively positioned on caching chamber 11 left side wall, and ink fill port 12 is arranged on above insulating liquid charging port 13, and insulating liquid absorbed layer 15 is arranged on below ink outlet 14.Ink fill port 12 connects with print cartridge 4, and insulating liquid charging port 13 connects the insulating liquid container 5 equipped with insulating liquid.Ink outlet 14 is positioned at the right side wall in caching chamber 11, connects with ink entrance 21.Insulating liquid charging port 13 arranges motor-driven valve 131.Insulating liquid is incompatible with the ink in print cartridge, and the density of insulating liquid is less than the density of print cartridge ink inside.Insulating liquid absorbed layer 15 is removable to be arranged on below described ink outlet 14, insulating liquid absorbed layer 15 is more than the insulating liquid absorbed layer 15 absorptivity to print cartridge ink inside to the absorptivity of insulating liquid, and insulating liquid absorbed layer 15 is provided for detecting insulating liquid the most absorbed detection device.
Cleaning device includes cleaning head 221, recovery tube 222, negative pressure recycling box 223, and cleaning head 221 is arranged on bottom minitype piston 22, exports 32 for cleaning nozzle.Recovery tube 222 connects cleaning head 221 and negative pressure recycling box 223.Cleaning head 221 includes the cleaning wall 2211 being arranged on surface；Recovery tube 222 includes the sub-pipes 2221 being embedded in cleaning wall surface, and connects the main pipeline 2222 of sub-pipes and negative pressure recycling box.Sub-pipes 2221 has multiple, and is evenly distributed on the surface of cleaning wall 2211.Cleaning wall surface also sets up Clean Brush for cleaning.
Passage 33 includes conduit wall, and conduit wall is sequentially provided with deformation layer 331, zone of heating 332 and electrostatic layer 333 from the inside to the outside.Deformation layer 331 includes the Piezoelectric Driving plate 3311 set gradually along the ink flow direction.The inwall of the inking chamber above nozzle is arranged the most respectively with the Piezoelectric Driving plate once arranged along the ink flow direction one to one, for controlling the switch of Piezoelectric Driving plate.Switch includes being embedded in the conducting block 23 being made up of conductive material such as copper of inking chamber inwall, and the both sides outer wall of minitype piston 22 arranges the power supply bar 224 corresponding with conducting block 23, and power supply bar 224 is electrically connected with power supply, is powered for Piezoelectric Driving plate 3311 by conducting block 23.When minitype piston 22 from top to bottom moves in inking chamber, power supply bar 224 moves closer to conducting block 23.Power supply bar 224 is less than the conducting block 23 length at vertical direction in the length of vertical direction, power supply bar 224 from top to bottom transports along with minitype piston, when touching conducting block 23, turn on the circuit between the Piezoelectric Driving plate 3311 that power supply is corresponding with conducting block 23 so that Piezoelectric Driving plate 3311 produces the deformation towards nozzle interior bending after energising.Along with minitype piston continue move downward, power supply bar 224 leaves first conducting block, mobile second conducting block to this conducting block, drives the Piezoelectric Driving plate generation deformation that second conducting block is corresponding, by that analogy.During from top to bottom running along with minitype piston, generation deformation the most once opened by Piezoelectric Driving plate, promotes the ink flow down (such as Fig. 4) of passage wall surface.Zone of heating 332 includes Electric radiant Heating Film, and conduit wall is heated by Electric radiant Heating Film, prevents ink dry and hard at passage wall surface.Electrostatic layer 333 includes electrostatic film, and electrostatic film produces electrostatic, to ink particles generation effect so that ink particles leaving channel wall surface, avoids ink residue at passage wall surface as far as possible.
During printing, ink is entered in inking chamber through ink entrance by ink inlet tube, then is sprayed by the nozzle identical with inking chamber, completes to print.Minitype piston is airtight with described inking chamber to be slidably connected, and prints and can continue to move downward in described inking chamber under the control of described piston controller after terminating, and is released by the ink of residual in described inking chamber.
The course of work of the printer head of the present invention is as follows:
When needing to change print cartridge, first turn on motor-driven valve and the insulating liquid in insulating liquid charging port is flowed out, cover the ink surface in caching chamber.When ink below insulating liquid is used up, insulating liquid is isolated liquid absorbed layer and absorbs, and detection device detects that chaotropic reminds user after being absorbed.Now, user can be according to the new print cartridge of prompting changing of detection device, it is to avoid the contacts ink in new and old print cartridge and the generation harmful effect that interacts.Meanwhile, piston moves downward under the promotion of piston controller, and minitype piston is during pressure down, and power supply bar contacts successively with conducting block, opens Piezoelectric Driving plate and flows to act on successively produce deformation along ink, promotes the ink flow down of passage wall surface.Deformation layer produces the ink of deformation guiding channel wall surface and flows downwardly to outlet along conduit wall.Conduit wall is being heated by zone of heating, prevents ink dry and hard at passage wall surface.It is positioned at the electrostatic of electrostatic layer generation of most surface to ink particles generation effect so that ink particles leaving channel wall surface.By deformation, heating and the multiple action of electrostatic, reduce the ink being attached on conduit wall.During minitype piston continues down motion, reclaim cleaning head and be pushed in the outlet of shower nozzle.Rotary electric machine drives and reclaims cleaning head rotation so that the cleaning brush in cleaning wall sweeps out a mouthful inwall.While cleaning, negative pressure recycling box is communicated by the sub-pipes of recovery tube with cleaning wall surface, and the residue that its negative pressure produced makes cleaning produce sucks through sub-pipes, is inhaled into the storage of negative pressure recycling box after main pipeline converges.
Although being described in conjunction with the accompanying embodiments of the present invention, but those of ordinary skill in the art can make various deformation or amendment within the scope of the appended claims.
