The magenta dyes include the compounds which simultaneously contain carboxyl group, sulfonic acid group and the carbonyl propyl sulfurylsulfonic acid on the anthrapyridone skeleton, showing in the form of general formula (I) or their mixtures. In the general formula (I): A may be cation M | 07-17-2014 |
20130135402 | NEGATIVE-PRESSURE INK CARTRIDGE REFILLING DEVICE, SYSTEM AND METHOD - The invention relates to a negative-pressure ink cartridge refilling device, system and method. The device comprises an ink container used to store ink, an ink injection channel, an aspirator and a suction channel communicated with the ink container, wherein one end of the ink injection channel is an ink inlet end while the other end is an ink outlet end connected with the ink cartridge to be refilled; a sucking opening connected with the aspirator is formed on the suction channel; and the inlet end is disposed above the ink level surface of the ink container. Therefore, the ink in the ink container cannot be overflowed via the ink injection channel regardless of the environmental factors, and thus the technical problem that the phenomenon of ink splash tends to occur when the traditional negative-pressure ink cartridge refilling device is used by a user for the first time can be solved. | 05-30-2013 |
20130093821 | INK CARTRIDGE ON INKJET PRINTER - An inkjet printer, which comprises a slide lid slideably connected with the cartridge body, wherein a fixed clamp is formed on both sides of the cartridge body respectively; a movable wall which is engaged and fastened with the fixed clamp at the end is formed on both sides of the slide lid respectively; and a friction force generating component is arranged on one side of the movable wall. Due to the friction forces generated by the friction force generating components, two sidewalls of the movable walls are tightly engaged with the inner wall of the ink cartridge bin of the printer to lock the ink cartridge and fix the ink cartridge into the ink cartridge bin of the printer. The technical problems of poor contact of a chip and abnormal disengagement of an ink container as locking members are loosened when the ink cartridge on the printer can be solved. | 04-18-2013 |
20130061982 | INK CARTRIDGE REFILLING DEVICE - The present invention provides an ink cartridge refilling device, which comprises an ink container used for storing ink, an air inlet channel communicated with the ink container and introduced outside air into the ink container, a suction channel communicated with the ink cartridge and connected with an aspirator to suck air in the ink cartridge, an ink injection channel communicated with an ink injection opening of the ink cartridge and formed on the ink container and a re-suction channel which is communicated with an ink outlet of the ink cartridge and connected with the aspirator to suck ink at the ink outlet after the ink cartridge is refilled. The ink cartridge refilling device has the advantage that: air bubbles can be prevented from being attached to the upper part of a piezoelectric transducer near the ink outlet. | 03-14-2013 |
20120281040 | INK CARTRIDGE USED FOR AN INKJET PRINTER - This invention relates to an ink cartridge used for an inkjet printer, comprising an ink storage chamber, an ink outlet and an air inlet, and a detection component is designed inside the ink storage chamber for detecting residual ink volume. The ink storage chamber comprises an ink detection chamber and a relatively enclosed ink refilling chamber with an opening at the lower part. The opening of the ink refilling chamber is inside the ink detection chamber. The detection component is designed inside the ink detection chamber. | 11-08-2012 |
20120218357 | INK CARTRIDGE FOR INK JET PRINTER - The present invention relates to an ink cartridge for an ink jet printer, comprising an ink storage chamber formed by a concave housing ( | 08-30-2012 |
20120182365 | INK CARTRIDGE FOR AN INK JET PRINTER - The invention relates to an ink cartridge for an ink jet printer. The ink cartridge comprises a cartridge body and a detection mechanism for detecting the ink cartridge and residual quantity of ink, wherein the cartridge body comprises an ink tank for storing ink, an ink outlet for supplying ink to a printing head of the printer and an air inlet, the ink tank comprises a first ink chamber and a second ink chamber, a first negative pressure mechanism and a second negative pressure mechanism are arranged between the first ink chamber and the second cavity, the first negative pressure mechanism and the second negative pressure mechanism cooperatively control the ink inside the first ink chamber to be consumed preferentially than the ink inside the second ink chamber, and the second negative pressure mechanism generates negative pressure when a certain quantity of ink inside the ink tank is used for printing. Since negative pressure inside the ink tank is not generated until the used ink inside the ink tank reaches a certain quantity, i.e., negative pressure is generated only in case that the residual quantity of ink is small in the end, the technical problem that constant negative pressure in the process of using the ink cartridge leads to the damage and deformation of the parts inside the ink cartridge which impact on the quality of printing can be avoided. | 07-19-2012 |
20120176452 | METHOD FOR REFILLING INK INTO INK CARTRIDGE AND FILLING TOOL - A method for refilling ink into ink cartridge comprises: I. hermetically connecting an ink injection port of the ink cartridge to an ink supply port of an ink storage container of an ink filling tool which is not completely filled with ink, connecting a suction unit to the ink storage container of the ink filling tool and sealing the ink cartridge; II. sucking out the air inside the ink storage container of the ink filling tool by the suction unit; III. releasing the suction unit so that the ink inside the ink storage container of the ink filling tool is automatically absorbed by the ink cartridge due to atmospheric pressure balance. An ink filling tool used in the method described above also is provided. | 07-12-2012 |
20120056957 | ADAPTER AND AN INK CARTRIDGE MOUNTED ON AN INK-JET PRINTER - The invention relates to an adapter and an ink cartridge mounted on an ink-jet printer. An adapter comprises an inner chamber for accommodating the ink cartridge and a chip set on the adapter, wherein the said chip has a contact surface with the printer, the contact surface provided with an information contact and two electrical detecting contacts; a non-contact trigger switch is set on the back surface of the said chip opposite to the two electrical detecting contacts; the said non-contact trigger switch is electrically connected with two electrical detecting contacts respectively; the said non-contact trigger switch is triggered to become disconnected at least once by the non-contact trigger mechanism on the ink cartridge when the ink cartridge is being inserted into the printer and is not triggered by the non-contact trigger mechanism so as to keep the connected status after the ink cartridge is inserted into the printer. | 03-08-2012 |
