Problems solved by technology

Although the above two patents have new features and progress in terms of saving consumables and environmental protection, there are still relatively deficiencies in practice. The ink cartridge on the print head is provided by the external ink cartridge at any time. When the liquid level of the external ink drops to a certain position difference, the change in pressure difference will directly affect the printing or drawing effect
In addition, the connection port is not standardized, and the ink supply device and the printer can only be used one-to-one. When the user replaces the printer, he needs to choose a matching ink supply device, which increases the cost; , there will also be a phenomenon that the ink in the ink box in the printer and the ink in the ink tank of the ink supply unit are in a static state, so that the ink in the ink box will flow back into the ink tank of the ink supply unit due to the water level difference

[0054] by 12- Figure 18 As shown, according to the needs of the present invention, an ink conduit cut-off switch is arranged on the ink conduit in the ink supply housing. 20 in the figure is a switch housing. A valve body 21 with seven independent cavities 22 arranged side by side is arranged on the lower part of the switch housing 20. A An ink inlet pipeline interface 23 and an ink outlet pipeline interface 24 . The top of the valve body 21 is connected with an ink tube closing key 26 through a pressure spring 35, and the lower part of the ink tube closing key is fixedly connected with a valve stem 25 corresponding to the independent cavity 22 of the valve body and inserted into the cavity. An annular sealing ring 34 is also provided on the periphery of the lower part. On the outer wall of ink tube closing key 26, a movable lock key socket 27 is symmetrically arranged, and a switch housing 20 corresponding to the movable lock key socket 27 is provided with a movable lock k...

Abstract

The automatic ink feeder for ink jet printer includes casing, ink bin with top ink injecting port, and ink duct set in the outlet of the ink bin for connecting the ink cartridge of ink jet printer. The technological key points include the liquid level sensor set inside the ink bin and connected with detection circuit, sampling, comparing and amplifying circuit, control circuit and music alarm circuit successively; and the double valve body non-return valve in the ink path between the ink bin and the ink cartridge and with two independent valve structures. The present invention solves the problem that ink feeder may be used in printer in only one-to-one mode, and makes it possible for one ink feeder to be connected with different ink cartridge and different printer via a standard connecting port.

Description

technical field [0001] The invention belongs to the technical field of ink-jet printing, in particular to an automatic ink supply device for an ink-jet printer that automatically supplies ink to a print cartridge of the ink-jet printer. Background technique [0002] As everyone knows, along with the expansion of computer technology application field, the use of color ink-jet printer is quite common. However, imported inkjet printers and corresponding special inks are generally used in China, but the price of these imported products is very expensive, and when using imported disposable ink cartridges, when any color in the color ink cartridge is used up, the entire ink cartridge will be damaged. It can no longer be used, which discourages consumers. According to relevant data reports, when the printer shows that the ink is exhausted and needs to be replaced with a new ink cartridge, there is still a lot of ink in the ink cartridge. It is obviously unfair for consumers to bea...
