The ink supplying needles of a printing head can be inserted into the cleaning box. The pressure adjusting mechanism is used for adjusting the pressure in the cleaning box. The bottom cleaning box filled with cleaning fluid is disposed under the nozzles of the printing head and the nozzles are immersed in the cleaning fluid. The printing head cleaning device has advantages that the printing head can be effectively cleaned without detaching the printing head and that the printing head cannot be damaged.
Description
Technical field
The utility model relates to a kind of cleaning device that the printhead of ink jet printing device is cleaned.
Background technology
Ink jet printing device utilizes printhead that the ink in the print cartridge is sprayed on the print media and forms image and print.The printhead of ink jet printing device generally all is fixed on to be printed in the word car, and comprise that but being positioned at the top is connected with print cartridge with the ink supply pin from print cartridge supply ink to printhead inside, and be positioned at the below for the nozzle of ejection ink on print media, and have the extremely small ink channel of several diameters in the printhead, the quantity of these passages equals the nozzle quantity of ink-jet printer.Each channel interior energy of attachment produces the performance element of vibration or heat, when the control circuit of printhead receive drive signal after, namely drive these performance elements and produce vibration or high temperature, with the extruding of the ink in the passage or produce bubble and spray from nozzle.
In actual applications, can use dissimilar inks for different demand ink jet printing devices, as the ink of paint ink, dye ink or other types.Because when dissimilar ink mixes, generally can react and produce precipitation etc., use dissimilar inks with after, tend to stop up in the printhead of ink jet printing device, can't normally print, so need clean printhead.A kind of cleaning method cleans for printhead is disassembled from printing word car, but the dismounting of printhead generally needs the professional to operate, and is very inconvenient concerning the general user.Another kind method is the printhead cleaning procedure that utilizes ink jet printing device to carry, but when having bigger in the ink channel of printhead or during more deposit, the printhead cleaning procedure that utilizes ink jet printing device to carry can't clean up printhead.For printhead can be cleaned up, a kind of method of in printhead, pressurizeing and cleaning with cleaning fluid occurred, but because ink channel is comparatively meticulous, when cleaning with pressure method, tended to owing to the improper printhead that causes of pressure control damages.
Therefore need a kind of cleaning device that printhead can effectively clean printhead and can not damage printhead that need not to dismantle.
Summary of the invention
The purpose of this utility model provides a kind of printhead cleaning device that printhead can effectively clean printhead and can not damage printhead that need not to dismantle.
For achieving the above object, the printhead cleaning device that the utility model provides comprises: the last cleaning box of cleaning fluid is housed, and the ink supply pin of printhead can insert in the cleaning box; The pressure regulating mechanism that can be connected with last cleaning box is used for changing the pressure of going up in the cleaning box; The following cleaning box of cleaning fluid is housed, be arranged on the nozzle below of printhead, and nozzle immerses in the cleaning fluid.
By above scheme as seen, nozzle immerses in the cleaning fluid, can soak nozzle, when the pressure on pressure regulating mechanism makes in the cleaning box increases, cleaning fluid can enter printhead inside from the ink supply pin, and the ink channel in the printhead soaked, when the pressure on making in the cleaning box reduces, cleaning fluid in the following cleaning box can enter printhead inside from nozzle, and the ink channel in the printhead soaked, thereby can clean repeatedly printhead from both direction, pressure need not excessive and can not damage printhead, and after soaking, the deposit in the printhead is easier to clean up.Therefore, when using this device to clean printhead, can effectively clean and can not damage printhead.
More concrete scheme is that pressure regulating mechanism comprises the booster body that makes the increase of cleaning box internal pressure and the mechanism of decompressor that the cleaning box internal pressure is reduced.Realize the upward variation of cleaning box internal pressure by booster body and the mechanism of decompressor.
Scheme is that booster body comprises first aspirating mechanism that is connected by intake valve with the external world more specifically.As seen from the above, can realize increase to last cleaning box internal pressure by first aspirating mechanism and intake valve.
Another more specifically scheme be that the mechanism of decompressor comprises second aspirating mechanism that is connected by air outlet valve with the external world.As seen from the above, can realize reducing last cleaning box internal pressure by second aspirating mechanism and air outlet valve.
Preferably, the connecting path between booster body and the last cleaning box is provided with first switch.As seen from the above, the setting of first switch can make being connected of cleaning box and booster body or disconnect more convenient.
Preferably, the connecting path between the mechanism of decompressor and the last cleaning box is provided with second switch.As seen from the above, the setting of second switch can make being connected of cleaning box and the mechanism of decompressor or disconnect more convenient.
Preferably, be provided with porous material with the nozzle butt in the following cleaning box.Produce certain negative pressure by porous material, make ink be easier to enter in the printhead from nozzle.During cleaning box, because the suction-operated of porous material, cleaning fluid can not be sprinkled upon in the ink jet printing device under taking out below printhead.
Preferably, following cleaning box is provided with the liquid level display part.The liquid level that prevents down the cleaning box cleaning liquid inside is too high, and cleaning fluid flows out from the ink supply pin.
Preferably, be provided with the cleaning fluid discharge hole bottom the following cleaning box.After cleaning is finished, can be earlier discharging from the cleaning fluid discharge hole, with prevent down cleaning box in the ink jet printing device during taking-up cleaning fluid be sprinkled upon in the ink jet printing device.
Preferably, also comprise the cleaning fluid adding container, the cleaning fluid adding container is communicated with last cleaning box or following cleaning box.After cleaning fluid in last cleaning box or following cleaning box is contaminated, can emit the cleaning fluid in it, with the cleaning fluid adding container last cleaning box or following cleaning box be carried out replenishing of cleaning fluid then.
