Generally, the ink cartridges of such printers on the market achieve inkjet control through the cooperation of a single gas cylinder and a single ink tank. However, the cooperation mode of a single gas cylinder and a single ink tank requires the X-direction dimension of the printing carriage to be long enough, which will reduce the effective printing width and increase the size of the whole machine. Especially for the case where there is a height difference between the nozzles, it cannot meet the inkjet control of nozzles with different heights. Summary of the Utility Model

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example

[0018] like Figure 1 As shown, Figure 1 Shown is an overall schematic diagram of an ink cartridge with dual conjoined ink tanks in an embodiment;

[0019] The device includes:

[0020] Double-connected ink tanks, multiple double-connected ink tanks are arranged in parallel;

[0021] The double-jointed ink tank includes an ink tank 11 and an ink tank 2 12. The ink tank 11 and the ink tank 2 12 each have an independent ink storage cavity. The bottom ends of the ink tank 11 and the ink tank 2 12 are respectively provided with a nozzle 15 and a nozzle 2 16. The nozzle 15 and the nozzle 2 16 have different ink spraying heights.

[0022] Double-connected gas tank. The double-connected gas tank includes gas tank one 21 and gas tank two 22. Gas tank one 21 and gas tank two 22 are respectively connected to ink tank one 11 and ink tank two 12, and gas tank one 21 and gas tank two 22 generate negative pressure in ink tank one 11 and ink tank two 12 to adsorb ink and control the inkjet volume. The magnitude of the negative pressure generated in ink tank one 11 and ink tank two 12 matches their inkjet height.

[0023] Ink tank one 11 and ink tank two 12 in the double-connected ink tank work independently, can store different colors of ink internally, and are respectively ejected through nozzle one 15 and nozzle two 16. Moreover, nozzle one 15 and nozzle two 16 have different inkjet heights, can simultaneously achieve multi-line printing, and improve the printing efficiency. For nozzles one 15 and two 16 with different heights, by providing gas tank one 21 and gas tank two 22 respectively connected to them to provide different negative pressures, it can specifically enable nozzles one 15 and two 16 to achieve inkjet, solving the problem that nozzles with different inkjet heights require different negative pressures.

[0024] Specifically, the double-connected ink tank can be connected to a mechanism capable of generating negative pressure in the existing external technology and communicated to the double-connected ink tank.

[0025] Arranging multiple double-connected ink tanks side by side can reduce the size of the print head. Changing from a horizontal layout to a depth direction layout, arranging the nozzles vertically in a column is more advantageous, enabling a high-density arrangement of nozzles and reducing the space occupied by the inkjet component.

[0026] As Figure 1 shown, Figure 1 It shows an overall schematic diagram of an ink cartridge with a double-connected ink tank in the embodiment;

[0027] At the top of ink tank one 11 and ink tank two 12, there are respectively ink tank interface one 13 and ink tank interface two 14. At the top of gas tank one 21 and gas tank two 22, there are respectively gas tank interface one 23 and gas tank interface two 24. Ink tank interface one 13 and gas tank interface one 23, ink tank interface two 14 and gas tank interface two 24 are all connected through the provided connecting pipe 31.

[0028] The connection between the double-connected ink tank and the double-connected gas tank is realized through the provided ink tank interface one 13, ink tank interface two 14, gas tank interface one 23, gas tank interface two 24, and connecting pipe 31.

[0029] On ink tank one 11, there is also valve one 17 provided. On ink tank two 12, there is valve two 18 provided. Valve one 17 and valve two 18 respectively control the opening and closing of nozzle one 15 and nozzle two 16.

[0030] On both ink tank one 11 and ink tank two 12, there is a liquid level sensor one 41 extending into their ink storage cavities. On both gas tank one 21 and gas tank two 22, there is a liquid level sensor two 42 extending into their internal cavities.

[0031] The liquid level sensor 1-41 set in the double-connected ink tank is used to monitor the liquid level height of the ink inside the ink storage cavity, so as to ensure the continuous reminder supply of ink.

[0032] For the liquid level sensor 2-42 set in the double-connected gas tank, when the liquid level sensor 1-41 in the double-connected ink tank fails and the ink is over-supplied, the ink will be sucked into the double-connected gas tank through negative pressure. At this time, the liquid level sensor 2-42 will work and transmit the signal to the controller to stop the ink supply or connect the alarm for fault alarm.

[0033] Working principle: Ink tank 1-11 and ink tank 1-12 in the double-connected ink tank set in this device work independently. Negative pressure is generated in ink tank 1-11 and ink tank 1-12 through gas tank 1-21 and gas tank 1-22 to adsorb ink and control the inkjet volume, and the magnitude of the negative pressure generated in ink tank 1-11 and ink tank 1-12 matches the different inkjet heights of ink tank 1-11 and ink tank 1-12.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
