Description

Technical Field

[0001] The utility model relates to the technical field of inkjet printers, in particular to an ink box for inkjet printers. Background Art

[0002] An inkjet printer is a device that uses software control to mark products in a non-contact manner. Under the pressure of the ink supply pump, the ink flows from the ink tank through the ink pipeline, adjusts the pressure and viscosity, and enters the spray gun. As the pressure continues, the ink is ejected from the nozzle.

[0003] The ink tank used in the existing inkjet printer is a box structure with a cover, and a micro pump is arranged on the box to transport the ink. However, in the existing ink tank, the micro pump is provided with a suction pipe connected to the inside of the box, and no filtering structure is arranged at the end of the suction pipe. Impurities in the ink enter the micro pump along the suction pipe and are finally sprayed out from the nozzle. Impurities cannot be filtered and easily lead to nozzle blockage, thereby affecting the inkjet effect. In order to ensure the normal suction of the ink, an air inlet is arranged on the ink tank, and no dust-proof structure is arranged at the air inlet. Dust easily enters the ink tank and affects the cleanliness of the ink. Utility Model Content

[0021] When installing the ink tank, the ink tank is set at a suitable position on the inkjet printer, and the suction structure 7 is connected to the liquid inlet head 5. After opening the end cover structure 8 on the injection tube 3, ink is injected into the interior of the box body 1 through the injection tube 3. After the ink is added, the end cover body 801 is connected to the injection tube 3, and the cannula 802 is inserted into the injection tube 3. After starting the micro pump 4, the ink enters the micro pump 4 through the suction structure 7 and the liquid inlet head 5, and then enters the corresponding pipeline through the discharge head 6, and finally sprays out from the nozzle of the spray gun, thereby realizing the inkjet operation. In this process, the suction structure 7 can play a filtering role. At the same time, the outside air enters the inner cavity 804 at the end cover body 801 and the cannula 802 through the air inlet channel 805 on the special-shaped tube 803, and finally enters the box body 1, ensuring the balance of air pressure inside and outside the box body 1 and ensuring the normal suction of ink. When necessary, the fixing screws 9 can be removed, and the box cover 2 can be taken down to inspect and replace the internal structure of the box body 1.

[0022] Through the above implementation scheme, the suction structure 7 includes a hose 701, a suction head 703 and a filter assembly 705, the hose 701 is connected to the liquid inlet head 5, the filter assembly 705 is installed on the suction head 703, and the suction head 703 is arranged at the lower end of the hose 701, the suction structure 7 also includes a connector 702 and an external thread 704, the connector 702 is arranged at the end of the hose 701, and the hose 701 is connected to the liquid inlet head 5 through the connector 702, the external thread 704 is arranged on the suction head 703, the filter assembly 705 includes a fixing ring 7051, a support rod 7052, a connecting frame 7053, an annular groove 7054 and a filter screen 7055, the fixing ring 7051 is installed on the suction head 703 through the external thread 704, the support rod 7052 is fixed on the fixing ring 7051, and the support rod 7052 is fixed on the fixing ring 70 51 is distributed in a circular array, a connecting frame 7053 is installed on the support rod 7052, an annular groove 7054 is set on the connecting frame 7053, and a filter screen 7055 is fixed on the inner side of the connecting frame 7053. Through the provided suction structure 7, the connector 702 at the end of the hose 701 is threadedly connected to the liquid inlet head 5, which is convenient for disassembly of the entire suction structure 7. A filter assembly 705 is installed on the suction head 703 through an external thread 704, which can effectively filter and prevent impurities from entering the micro pump 4 and the nozzle, avoiding blockage and ensuring the normal operation of the inkjet printer. A support rod 7052 is set on the filter assembly 705. When the suction head 703 is placed, the support rod 7052 plays a role of lifting and supporting, so that the suction head 703 will not contact the bottom surface of the inner part of the box body 1, thereby ensuring the normal operation of the suction work.

[0023] When installing the suction structure 7, first use the external thread 704 to install the fixing ring 7051 on the suction head 703 until the lower end of the suction head 703 is inserted into the annular groove 7054. At this time, the filter screen 7055 is located at the end position of the suction head 703, and then the hose 701 is installed on the liquid inlet head 5 using the connecting head 702. Under the action of gravity, the suction head 703 and the filter assembly 705 are located at the inner bottom end of the box body 1, and the support rod 7052 plays a supporting role, so that the suction head 703 will not directly contact the inner bottom surface of the box body 1. During use, the micro pump 4 generates suction force when it runs, and the ink enters the suction head 703 after being filtered by the filter screen 7055, and then enters the micro pump 4 through the hose 701 and the liquid inlet head 5, and finally is sprayed out from the nozzle after being transported through the pipeline, thus realizing the coding operation.
