Description

Technical Field

[0001] The utility model belongs to the technical field of ink tanks, and particularly relates to a double-chamber secondary ink tank assembly. Background Art

[0002] In a modern office environment, inkjet printers are widely popular due to their high printing quality and good cost-effectiveness.

[0003] When the existing ink tank is in use, its usable capacity has certain limitations, and only one color of ink can be stored in the ink tank. Moreover, it is impossible to directly observe the ink storage amount in the ink tank, which affects the use efficiency. Summary of the Utility Model

[0004] In view of the problems existing in the prior art, the utility model provides the following technical solutions:

[0005] A double-chamber secondary ink tank assembly includes a tank body. An upper cover plate is installed at the top of the tank body, and the upper cover plate and the tank body are locked and installed through a first bolt and a first tower joint. A PTFE ink tank is installed in the tank body, and the PTFE ink tank and the tank body are locked and installed through a second tower joint. The upper cover plate is penetrated by a liquid level sensor, and the bottom end of the liquid level sensor is placed in the tank body.

[0006] The design of the double-chamber PTFE ink tank allows one color of ink or different colors of ink to be filled in the PTFE ink tank. The full-tank single-chamber volume of the PTFE ink tank is more than 500 milliliters, and the total volume of the double chambers is more than 1000 milliliters, which significantly increases the capacity volume intuitively and physically.

[0007] Preferably, a transparent window is installed on the side wall of the tank body, and the tank body and the transparent window are installed and locked through multiple groups of second bolts.

[0008] The design of the transparent visible window is adopted. The small holes near the bottom are used to connect the PTFE ink tank and the observation hole to form a communicating vessel. The small holes near the upper part are used to connect the negative pressure and also form a communicating vessel. In this way, the ink liquid level in the window is the same as that in the PTFE ink tank, and the negative pressure at the bottom is also the same as that in the PTFE ink tank. The liquid level in the window is the real liquid level of the PTFE ink tank. The connection body can conveniently and directly observe the fluid color and stock state in the tank body.

[0009] Preferably, the material of the tank body is made of high-strength polyoxymethylene material.

[0010] It can resist corrosion and aging and has high strength.

[0011] Preferably, multiple groups of ink outlets are installed at the bottom end of the tank body, and the input ends of the ink outlets are connected to the output ends of electromagnetic valves. The ink outlets are installed at the bottom end of the tank body.

[0012] The design of multiple ink outlets can meet customers' needs for multiple outlets and large flow rates. The device adopts a bottom ink inlet design to prevent the generation of bubbles, which can effectively eliminate bubbles.

[0013] The beneficial effects of the utility model are:

[0014] In this application, the dual-chamber ink tank design can be filled with one color ink or different colors of ink; large capacity, a full tank with a single chamber volume of more than 500 ml; a double chamber with a total volume of more than 1000 ml;

[0015] It adopts a transparent window design. The small hole near the bottom is used to connect the ink tank and the observation hole to form a communicating vessel. The small hole near the top is used to connect the negative pressure, also forming a communicating vessel. In this way, the ink level in the window is consistent with the ink tank, and the negative pressure at the bottom is also consistent with the ink tank. The liquid level in the window is the actual ink tank level. The connection makes it very convenient and intuitive to observe the color and inventory status of the fluid in the tank.
