The specific embodiment:
The print cartridge that is used for ink-jet printer as shown in Figure 2, comprise 1 box body, be used to detect the testing agency of print cartridge and ink remaining amount, box body comprises the ink storage chamber that is used for storage ink, ink outlet port 7 and atmosphere import 2 to the printhead ink supply of printer, ink storage chamber comprises first inking chamber 20 and second inking chamber 21, be provided with weight valve 9 and floating valve 8 between first inking chamber 20 and second inking chamber 21, ink in weight valve 9 and floating valve 8 cooperation controls first inking chamber 20 preferentially consumes than the ink of second inking chamber 21, floating valve 8 makes the ink printed in the ink storage chamber just produce negative pressure to a certain amount of the time, and atmosphere import 2 is arranged on first inking chamber 20.
The testing agency of detecting print cartridge and ink remaining amount comprise with printer on first detection part 3 of first sensor coupling, with second detection part of second sensor matching on the printer be arranged at the software support cap 6 that communicates with ink storage chamber on the box body, second detection part comprises movable rod member 5 and is arranged at the fixed axis of box body, movable rod member is connected with the box body rotating shaft by fixed axis, the software support cap is positioned at movable rod member and sentences the movable rod member of butt when movable rod member position adjustments part surpasses the software support cap at correspondence position sagging under the gravity effect, box body is provided with on the antetheca of ink outlet port and also is provided with elastomeric element 4, elastomeric element 4 one ends are fixedlyed connected with the antetheca of box body, the other end by crooked can with the wall butt of ink-cases of printers spatial accommodation, elastomeric element 4 is provided with support level; Movable rod member is supported by the support level on the elastomeric element, and support level is the hollow-out parts that is arranged on the elastomeric element, and the antetheca that box body is provided with ink outlet port is provided with screens, and an end of elastomeric element is fixedlyed connected with box body by screens.
Wherein the print cartridge air outside enters box body 1 inside by the atmosphere import.The effect of ink outlet port 7 is by being transferred in the printhead of printer in the print cartridge 1 with ink.
First detection part 3 cooperates the first sensor 104 of printer to detect.After the print cartridge installation, first detection part 3 blocks the light that first sensor 104 illuminating parts send, and as shown in Figure 8, makes first sensor 104 light receivers not receive light.The print cartridge installation is detected successfully.
Second detection part 5 cooperates second sensor 102 of printer to detect, and after the print cartridge installation, second detection part 5 blocks the light that second sensor, 102 illuminating parts send, and makes second sensor, 102 light receivers not receive light.The print cartridge installation is detected successfully, as shown in Figure 8.
The effect of elastomeric element 4 is to cooperate the installation of second detection part to detect.Because in print cartridge is packed the process of printer into, have following state:
During beginning, the two sensors in the printer all is in on-state.With the print cartridge installation deeply, light sends from second sensor, 102 emission parts, block and can't get back to the acceptance division of second sensor 102 through movable rod member 5, these state second sensor 102 light paths disconnect, and first sensor 104 does not contact first detection part 3 and belongs to on-state.
Light sends from second sensor, 102 emission parts then, because the wall of elastomeric element 4 contact ink box warehouses 10, elastomeric element 4 is subjected to displacement, no longer support movable rod member 5, movable rod member 5 is subjected to displacement around fixed axis, and the displacement on second sensor, 102 directions of motion is greater than second sensor 102, second sensor, 102 sensed positions have been streaked in the detection position of at this moment movable rod member 5, light is mapped to the acceptance division of second sensor 102, these state second sensor 102 light paths are connected, and the light that the emission part of first sensor 104 sends is blocked by first detection part 3, and first sensor 104 light paths are in off-state.
With going deep into of print cartridge installation, light sends from second sensor, 102 emission parts, and this moment, movable rod member 5 was supported by the software support cap 6 at rear portion, as shown in Figure 4, stop to be subjected to displacement, and be in the detection position of second sensor 102, this moment, movable rod member 5 sheltered from the light that second sensor 102 sends, light can't be got back to second sensor, 102 receiving portions, these state second sensor 102 light paths disconnect, and the light that the emission part of first sensor 104 sends is still blocked by first detection part 3, and first sensor 104 light paths also are in off-state, and the ink entrance of printer cooperates with print cartridge ink outlet port 7, and smooth ink supply.
Elastomeric element 4 is in above process during original state, as shown in Figure 3, support movable rod member 5, during movable rod member 5 one time in the detection position of streaking second sensor 102, elastomeric element 4 just no longer supports movable rod member 5, and after this movable rod member 5 can be supported by software support cap 6.When print cartridge was taken out by printer, elastomeric element 4 can support movable rod member 5 again, and movable rod member 5 is resetted.So that repeat above installation process when installing once more.
Another effect of elastomeric element 4 is when print cartridge splits out printer, with the print cartridge bullet from ink box warehouse 10.This process be print cartridge when packing ink box warehouse 10 into, as shown in Figure 7, deformation can take place in elastomeric element 4, because after ink box warehouse covers 105 closures, can't reset after making elastomeric element 4 deformation, when ink box warehouse lid 105 was opened, elastomeric element 4 resetted, and print cartridge can be ejected.
The effect of software support cap 6 is after the print cartridge installation, supports movable rod member 5, makes second detection part 5 rest on the detection position of second sensor 102, detects successfully so that install, as shown in Figure 8.
Software support cap 6 comprises shown in Fig. 9 C: a gentle matter support membrane 61, can support movable rod member 5, and can change shrivelled according to internal pressure; One communication passage 62 can link to each other with inking chamber; One software support cap sealing ribs, 63 salable inking chambers are shown in Fig. 9 D.
Another effect is to cooperate the China ink of printer to detect to the greatest extent, and China ink detects to the greatest extent can be by following process:
Along with the consumption of printing, quantity of ink constantly reduces, when the ink of print cartridge exhausts, under the swabbing action of printer ink-providing pin, since box body 1 internal buoyancy valve 8, the adjusting of weight valve 9, the gentle matter support membrane 61 of software support cap 6 was shrivelled when ink was soon used up, gentle matter support membrane 61 no longer supports movable rod member 5, and movable rod member 5 is continued to move by the gravity effect, leaves the position of blocking second sensor, 102 light paths.Light direct beam is to light receiving element, and this moment, the first sensor 104 of printer was blocked, and second sensor is not blocked, thereby the printer prompts ink is about to exhaust, and sends the signal prompt user then.
Floating valve 8, the effect of weight valve 9 are to regulate the print cartridge pressure inside, make software support cap 6 inner shrivelled, as shown in Figure 5, and then reach the purpose that China ink detects to the greatest extent.
Wherein floating valve 8 comprises: a buoyancy valve seat 81 and the buoyancy spool 82 shown in Fig. 9 A, wherein buoyancy valve seat 81 is characterised in that a seal spool portion 811 that cooperates with buoyancy spool 82, a fluid passage 812 that is used to be communicated with inking chamber and ink outlet port, reaching one can be fixing with valve seat 81, and makes the valve base sealing ribs 813 of valve seat 81 periphery sealings; A spool 82 is characterised in that its density less than ink, and can with valve base sealing portion 811 fitted seal fluid passages 812, shown in Fig. 9 B.
Wherein weight valve 9 comprises: a gravity valve seat 91 and a gravity spool 92, and wherein gravity valve seat 91 is the same with the architectural feature of buoyancy valve seat 81; A spool 92 is characterised in that its density greater than ink, and certain pressure intensity (>-3KPa) under can with valve base sealing portion fitted seal fluid passage, as shown in Figure 8.The negative pressure value of weight valve control is greater than the shrivelled Resistance Value of software support cap.
Floating valve 8, the control procedure of weight valve 9 is as follows:
When the ink in print cartridge does not also consume, the buoyancy spool of floating valve 8 82 since density less than ink, so buoyancy spool 82 floats on the ink top, floating valve 8 is in opening, Ink Cartridge inner pressure is identical with the outside.The gravity spool 92 of weight valve 9 is because density greater than ink, so gravity spool 92 cooperates with valve base sealing portion, makes weight valve be in closure state.The type of flow of ink is shown in the dotted line among Figure 10.
Along with the consumption of printing, the ink position constantly descends, and when cooperating with valve base sealing portion to buoyancy spool 82, floating valve 8 closures because weight valve 9 also is in closure state, are in sealing state so close on the chamber of ink outlet port.Because the ink supply pin of printer has certain suction force, so can't influence printing.
At floating valve 8 and weight valve 9 all after the closure, along with the consumption of printing, the pressure of the inking chamber that is communicated with software support cap 6 reduces gradually, the arrival certain value (0.5----3KPa) time, second detection part 5 is no longer supported in flexible support film 61 distortion of software support cap 6.This moment, the printer prompts ink was about to exhaust (the interior ink of print cartridge this moment also has 2-3ml).
After the prompting China ink will be use up, the ink supply pin of printer also can constantly aspirate ink, when ink outlet port pressure reach certain value (≤-3KPa) time, because the pressure that the pressure difference in atmospheric pressure and the chamber produces can overcome the gravity of the gravity spool 92 of weight valve 9, gravity spool 92 leaves sealing station, and weight valve 9 is opened, and air can enter the inking chamber that is communicated with software support cap 6 by the fluid passage, as shown in Figure 6, Ci Shi fluid flows as shown in figure 11.When cavity pressure reduced, the insufficient pressure that pressure difference in atmospheric pressure and the chamber produces was during with the gravity of the gravity spool 92 that overcomes weight valve 9, and gravity spool 92 comes back to sealing station, and weight valve 9 is closed again.Along with consumption of ink, weight valve 9 constantly carries out the action of opening and closing, so that the counter balance pocket internal pressure is used up up to ink.
The control accuracy of this negative pressure control mode is higher, can control software support cap 6 pressure when shrivelled accurately, has guaranteed the accuracy that printer ink detects to the greatest extent.
