The specific embodiment
Print cartridge 1 as shown in Figure 2, and print cartridge 1 comprises: gas port 2, ink outlet port 7, the first detection parts 3, the second detection parts 5, negative pressure mechanism 8, compliant member 6, elastomeric element 4.
Wherein print cartridge 1 air outside enters print cartridge 1 inside by gas port.The effect of ink outlet port 7 is by being transferred in the printhead of printer in the print cartridge 1 with ink.
The effect of elastomeric element 4 is to cooperate 5 installations of second detection part to detect.Because in print cartridge 1 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 second detection part, these state second sensor 102 light paths disconnect, and first sensor 104 does not contact first detection part 7 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 second detection part 5, second detection part 5 is subjected to displacement around axle, and the displacement on second sensor, 102 directions of motion is greater than second sensor 102, at this moment second sensor, 102 sensed positions have been streaked in the detection position of second detection part 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, second detection part 5 was supported by the compliant member 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, second detection part 5 sheltered from the light that second sensor 102 sends, and light can't be got back to second sensor, 102 receiving portions, and 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, 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.
Another effect of elastomeric element 4 is when print cartridge splits out printer, with print cartridge 1 bullet from ink box warehouse 10.This process be print cartridge 1 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 1 can be ejected.
The effect of compliant member 6 is after the print cartridge installation, supports second detection part 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.
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 the adjusting of negative pressure mechanism in the box body 1, gentle matter support membrane 61 shrivelled the sinking of compliant member 6 when ink is soon used up, and gentle matter support membrane 61 no longer supports second detection part 5, second detection part 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.
The effect of negative pressure mechanism is to regulate print cartridge 1 pressure inside, makes compliant member 6 inner shrivelled sinking, and as shown in Figure 5, and then reaches the purpose that China ink detects to the greatest extent.
Negative pressure mechanism is made up of valve system 8 as shown in Figure 8,
Wherein valve system 8 comprises: a valve seat 81, shown in Fig. 9 A, with a spool 82, wherein valve seat 81 is characterised in that a seal spool portion 811 that cooperates with 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.
The control procedure of negative pressure mechanism is as follows:
When the ink in print cartridge 1 does not also consume, the spool of valve system 8 82 since density less than ink, so first spool 82 floats on the ink top, first valve system 8 is in opening, Ink Cartridge inner pressure is identical with the outside.
Along with the consumption of printing, the ink position constantly descends, and when spool 82 drops to the valve base sealing portion 811 of valve seat 81, begins to seal print cartridge (quantity of ink in the print cartridge is 2-3ml at this moment).Ink constantly consume and the effect of the suction force of printer under, the gentle matter support membrane 61 of compliant member 6 is shrivelled sagging, and no longer resets.When simultaneously the inside and outside pressure differential of print cartridge can overcome the maximum static friction force of spool 82 in the fluid passage 812 of valve seat 81, spool 82 passed the fluid passage 812 of valve seat 81.This moment, the valve system 8 of print cartridge was in opening, and lasted till that always China ink to the greatest extent.
The control accuracy of this negative pressure control mode is higher, can control compliant member 6 pressure when shrivelled accurately, has guaranteed the accuracy that printer ink detects to the greatest extent.
