Problems solved by technology

However, in the air bubble generator proposed by the above-mentioned known technology, the method for controlling the air bubbles to enter the ink tank is determined according to factors such as the surface tension of the ink itself, the static pressure of the ink, so the main shortcomings of the above-mentioned known technology include: 1. Adopt different When using different types of ink, the bubble generator must be redesigned due to the different surface tension of the ink itself
2. When the remaining amount of ink decreases, the static pressure of the ink changes accordingly, so that the function of the bubble generator to adjust the pressure is also limited.
3. In order to make the negative pressure value of the ink tank when the bubble enters is the designed negative pressure value, the bubble generator must be precisely designed, which will increase the difficulty of manufacturing and assembly

Embodiment Construction

[0013] refer to figure 1 and Figure 2, figure 1 It is an external view of the ink cartridge 10 of the present invention, and Fig. 2 is figure 1 An exploded view of the components of the ink cartridge 10. The ink cartridge 10 includes a casing 12 inside which is provided a lantern-shaped ink bag 14 for storing ink (see FIG. 2 ). There is a top cover 16 above the housing 12 , and a vent hole 18 is arranged on it to balance the pressure difference between the inside and outside of the housing 12 . The bottom end of the casing 12 is provided with an ink outlet 20, which communicates with the ink bag 14 for supplying ink to an inkjet head (not shown) for inkjet printing.

[0014] The ink cartridge 10 uses the ink bag 14 to store ink and provides ink through the ink outlet 20. In order to prevent the ink from seeping out from the ink outlet 20 when the ink is not supplied, the ink bag 14 must be maintained within a certain negative pressure range. , to ensure that the inkjet hea...

Abstract

An ink box for printer is composed of a shell, an ink bag containing ink, an ink outlet on shell, two saw-tooth structures and an elastic unit fixed to the top of ink bag. When the volume of ink bag is reduced due to ink consumption, it pulls the said elastic unit for applying a reactive force to it, so maintaining the negative pressure in ink bag.

Description

technical field [0001] The invention provides an ink box for an inkjet printing device, in particular to an ink box capable of automatically adjusting internal fluid pressure. Background technique [0002] With the increasing popularity of personal and home computers, and the increasing demand for personal image output, inkjet printing devices have attracted many consumers due to their reasonable price and excellent printing quality, and have now become a popular choice for individuals, families and even companies. The most commonly used printing device for computer output. [0003] A general inkjet printing device usually has an inkjet head, which can move back and forth along a certain track, so as to inkjet print on a document to be printed. There is usually at least one ink box on the inkjet head. The main structure of the ink box is composed of a housing, which has an ink tank for storing ink, and an ink tank that communicates with the ink tank and is used to control i...
