Description

Technical Field

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

[0002] In inkjet printing technology, the performance of the ink supply system directly affects the printing quality and speed.

[0003] Traditional ink cartridge designs often have problems such as being prone to clogging. Especially after long-term use, the ink outlet is blocked by sediment in the ink, affecting the printing effect.

[0004] Therefore, we propose a secondary ink tank assembly and a solenoid valve to solve the above problems. Content of the Utility Model

[0005] In view of the problems existing in the prior art, the utility model proposes the following technical solutions:

[0006] A secondary ink tank assembly and a solenoid valve, including a tank body, an upper cover plate is installed at the top end of the tank body, a lower cover plate is installed at the bottom end of the tank body, the tank body and the upper cover plate are locked and connected by a first bolt, the tank body and the lower cover plate are locked and connected by a second bolt, a solenoid valve assembly is installed on the side wall of the tank body, and an ink outlet is installed on the side wall of the solenoid valve assembly.

[0007] By adjusting the position of the ink outlet, the sediment in the ink is deposited at the bottom of the tank body, preventing the sediment from being discharged from the ink outlet, avoiding blocking the pipeline or the nozzle, and thus solving the problem that the traditional clogging affects the printer function and the printing effect.

[0008] As a preference of the above technical solution, a liquid level switch is installed in the middle of the upper cover plate, and the bottom end of the liquid level switch extends deep into the tank body.

[0009] With the cooperation of the liquid level switch, the control of the ink volume in the tank body is completed.

[0010] As a preference of the above technical solution, a cut-off valve is installed at the bottom end of the lower cover plate.

[0011] Under normal conditions, the cut-off valve is in the closed state. However, when the ink sediment at the bottom of the tank body accumulates to a certain value, by opening the cut-off valve to the release state, the release operation of the sediment is completed, and it is not necessary to completely remove the tank body to complete the cleaning operation of the sediment.

[0012] A solenoid valve, a positive and negative pressure switching solenoid valve is installed at the top end of the upper cover plate, and the positive and negative pressure switching solenoid valve is locked and installed on the upper cover plate by a third bolt.

[0013] The equipped positive and negative pressure switching solenoid valve can conveniently switch the positive and negative pressures in the tank, thereby completing the operations of releasing and closing the release of the ink in the tank.

[0014] The beneficial effects of the present utility model are as follows:

[0015] (1) In this application, by adjusting the position of the ink outlet, the sediment in the ink is deposited at the bottom of the tank, preventing the sediment from being discharged from the ink outlet and avoiding blocking the pipeline or the nozzle, thereby solving the problem that the traditional printer function and printing effect are affected by the blockage situation.

[0016] (2) In this application, the equipped positive and negative pressure switching solenoid valve can conveniently switch the positive and negative pressures in the tank, thereby completing the operations of releasing and closing the release of the ink in the tank.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] In this application, aiming at the problem that the ink outlet is blocked by the sediment in the ink after the ink cartridge is used for a long time in the prior art, affecting the printing effect, by adjusting the position of the ink outlet 11, the sediment in the ink is deposited at the bottom of the tank body 1, preventing the sediment from being discharged from the ink outlet 11 and avoiding blocking the pipeline or the nozzle, thereby solving the problem that the traditional printer function and printing effect are affected by the blockage situation.

[0025] Such as Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, in the embodiment of the present utility model, the secondary ink tank assembly includes a tank body 1, an upper cover plate 3 is installed at the top end of the tank body 1, and a lower cover plate 2 is installed at the bottom end of the tank body 1. The tank body 1 and the upper cover plate 3 are locked and connected by a first bolt 6, and the tank body 1 and the lower cover plate 2 are locked and connected by a second bolt 7. An electromagnetic valve assembly 5 is installed on the side wall of the tank body 1, and an ink outlet 11 is installed on the side wall of the electromagnetic valve assembly 5; since the traditional ink outlet 11 is directly installed at the bottom end of the electromagnetic valve assembly 5, and the electromagnetic valve assembly 5 is also vertically installed on the tank body 1, and at the same time, since the outlet diameter of the bottom end of the ink outlet 11 is small, the sediment in the ink in the tank body 1 will block the ink outlet 11, affecting the printing effect. Now, the ink outlet 11 is installed on the side of the electromagnetic valve assembly 5 to form a unique anti-blocking design. By adjusting the position of the ink outlet 11, the sediment in the ink is deposited at the bottom of the tank body 1, preventing the sediment from being discharged from the ink outlet 11 and avoiding blocking the pipeline or the nozzle, thereby solving the problem that the traditional printer function and printing effect are affected by the blockage; a liquid level switch 4 is installed in the middle of the upper cover plate 3, and the bottom end of the liquid level switch 4 extends into the tank body 1; in cooperation with the liquid level switch 4, the control of the ink volume in the tank body 1 is completed; a cut-off valve 10 is installed at the bottom end of the lower cover plate 2; in the normal state, the cut-off valve is in the closed state to ensure the sealing effect in the tank body 1. However, when the ink sediment at the bottom of the tank body 1 accumulates to a certain value, by opening the cut-off valve 10 to the release state, the release operation of the sediment is completed, and it is not necessary to completely remove the tank body 1 to complete the cleaning operation of the sediment.

[0026] For the electromagnetic valve, a positive and negative pressure switching electromagnetic valve 8 is installed at the top end of the upper cover plate 3, and the positive and negative pressure switching electromagnetic valve 8 is locked and installed on the upper cover plate 3 by a third bolt 9; the equipped positive and negative pressure switching electromagnetic valve 8 can conveniently switch the positive and negative pressure in the tank body 1, thereby completing the operation of releasing and closing the release of the ink in the tank body 1.

[0027] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it.
