Description

TECHNICAL FIELD

[0001] The utility model relates to printing equipment technical field especially, and it is two -stage ink tank assembly of many ink storage cavities. BACKGROUND

[0002] Two-stage ink tank usually refers to the container used for storing and supplying ink in devices such as printers, UV flatbed printers, etc.

[0003] When the ink amount in the two-stage ink tank is controlled through the ink inlet and outlet of the two-stage ink tank, the ink amount information in the two-stage ink tank is usually obtained through a liquid level sensor or a transparent observation window. However, after the ink tank is filled with ink, a pressure difference may occur between the pressure of the window and the inside of the tank. When observing the condition of the tank through the window, the ink level of the window is consistent with that of the ink tank, i.e., the liquid level of the window is not the real ink tank level, which makes the ink amount information inaccurate and affects the printing effect.
