The specific embodiment
For realizing ink-jet printer cyclic ink supply system continuous ink feeding, and keep its negative regulation in certain limit, the China ink that requirement enters in cyclic ink supply system can not have any bubble, the present embodiment provides a kind of ink-jet printer that can eliminate bubble ink storage device, and solved print cartridge waste problem, saved printing cost.
As shown in Figure 1, ink-jet printer of the present invention ink storage device, comprises print cartridge 1 and for print cartridge 1 being added to black China ink bucket 2, between print cartridge 1 and China ink bucket 2, is provided with and adds China ink pipe 3 and add black control system.Describedly add black control system and comprise: be installed on the pump 41 adding on China ink pipe 3; Insert the liquid level sensor 42 in print cartridge 1 shell; The ECU 43 starting or stoping according to the metrical information control pump 41 of liquid level sensor 42.ECU 43 wherein can adopt single-chip microcomputer etc. to realize.And filter 5 is set for eliminating the impurity of China ink adding on China ink pipe 3.
When liquid level sensor 42 detects China ink in print cartridge 1 lower than lower limit, ECU 43 control pumps 41 start, China ink in China ink bucket 2 is pumped in print cartridge 1 via adding China ink pipe 3, when the China ink in print cartridge 1 being detected reaches higher limit, ECU 43 control pumps 41 stop, guaranteed the China ink amount of depositing in print cartridge 1, cyclic ink supply system is carried out continuously.
Add black control system and also can adopt siphon mode.Adopt above-mentioned design, avoided the waste of print cartridge 1, when China ink bucket 2 interior inks are used up, change China ink bucket 2, and adopt above-mentioned add black control system carry out automatically controlling make to add black easy to operate.
The consumption of Mo Tong 2 China and Mexico is realized by another liquid level sensor 6, and while China ink in China ink bucket 2 being detected lower than minimum liquid level, ECU 43 is reported to the police, and staff sees alarm signal, changes China ink bucket 2, or directly in China ink bucket 2, adds China ink, guarantees that it normally works.
As shown in Figures 2 and 3, print cartridge 1 comprises shell 11, defines this shell 11 and has the first relative side and the second side.Shell 11 comprises lower house 111 and upper cover 112, in lower house 111 and the junction of upper cover 112, is provided with sealing ring 113, prevents that China ink from spilling.
In shell 11 and be positioned at shell the first side and be provided with ink inlet tube 12 and ink reclaiming pipe 13; In shell 11 and be positioned at shell the second side and be provided with ink tube 14; At shell 11 tops and be positioned at shell the second side and be provided with outtake tube 15.Wherein, ink inlet tube 12 with add China ink pipe 3 and be connected for realization and add China ink to print cartridge 1; In the cyclic ink supply system of printing machine, China ink enters ink feeding system by ink tube 14, is delivered to shower nozzle and completes printing, at shower nozzle place, by 13 times China inks of ink reclaiming pipe, flow back in print cartridge.
In shell 11, be provided with deflector, described deflector comprise be located at the exit of ink inlet tube 12 and ink reclaiming pipe 13 and be obliquely installed lead black plate 171, and the upper plate 172 being connected with the upper end of leading black plate 171, between the upper end face of upper plate 172 and shell, form bubble channel C.
In deflector bottom, be provided with ink block board 16, between described ink block board 16 and the sidewall of shell, have for walking black gap B, between ink block board 16 and the inner bottom surface of shell, there is Rong Mo gap A, concrete, on the inner bottom surface of shell, be provided with back-up block 161, ink block board 16 is installed on back-up block 161.The lower end of ink tube 14 extend into Rong Mo gap A through ink block board 16, and preferred, the lower port of ink tube 14 is apart from shell 11 inner bottom surface 2mm.
In above-mentioned bubble channel C, be provided with for leading away and eliminate the bubble guiding device of bubble.
Because being tiltedly installed with, the exit of ink inlet tube 12 and ink reclaiming pipe 13 leads black plate 171, the interior black quantity not sufficient of print cartridge 1 enters the China ink in print cartridge 1 while adding China ink by ink inlet tube 12, or cyclic ink supply system enters the China ink in print cartridge 1 by 13 times China inks of ink reclaiming pipe, all beat at this and lead on black plate 171, then along leading black plate 171, flow down, through the gap B between ink block board 16 and side wall of outer shell, enter the Rong Mo gap A of outer casing bottom, at Mo Da, lead in black plate 171 and suitable its process flowing down, part bubble is led black plate 171 and is broken up, all the other bubbles can float over China ink above, when bubble runs up to a certain degree, bubble can move along the bubble channel C between end face on upper plate 172 and shell, then by the bubble guiding device in bubble channel C, in the process of leading away, eliminated, last remaining small part bubble is exported along the outtake tube 15 of cover top portion.Above-mentioned design has guaranteed there is no bubble in the Rong Mo gap A of ink block board 16 belows, thereby has guaranteed there is no bubble from ink tube 14 enters the China ink of cyclic ink supply system, and system pressure is stable, has improved printing quality.
Above-mentioned bubble guiding device can adopt following structure: comprise and be fixed on some on the shell flow deflectors that are arranged side by side 18, flow deflector 18 extends towards the direction of outtake tube 15.Adopt above-mentioned design, in the process that bubble moves in bubble channel C, be squeezed in the passageway between flow deflector 18, racked, further eliminate bubble.Preferably, flow deflector 18 is designed to arc line shaped, as shown in Figure 4, has not only lengthened thread, and has increased the collision opportunity of bubble and flow deflector inwall, has improved the effect of eliminating bubble.
In addition, winter, temperature was lower, the mobility variation of China ink, and when ink feeding system has just started to enter work, China ink needs just can circulate for a long time, has reduced operating efficiency.In order to address this problem, at the bottom of print cartridge 1 sticking heating plates 19, when system testing environment temperature is lower than 0 degree Celsius like this, automatically opens and heat, assurance cyclic ink supply system is worked smoothly.
In addition, convenient in order to clean print cartridge, in the bottom of shell, be provided with the conduit 20 of using for emptying ink, on conduit 20, be provided with switch.
Under above-mentioned instruction of the present invention; those skilled in the art can carry out various improvement and distortion on the basis of above-described embodiment; and these improvement and distortion; all drop in protection scope of the present invention; those skilled in the art should be understood that; above-mentioned specific descriptions are just better explained object of the present invention, and protection scope of the present invention is limited by claim and equivalent thereof.
