Description

A kind of ink cartridge and its installation method

technical field

The invention relates to the field of printers, in particular to an accessory ink box of an inkjet printer, especially an ink box and an installation method thereof.

Background technique

Inkjet printers are more commonly used printing tools. Although laser printers are relatively popular at present, due to the high maintenance cost of laser printers, inkjet printers still occupy a very large market share, especially in homes, shops, offices and other places.

An inkjet printer has an ink cartridge and its ink cartridge holder. At present, there are many ways to engage the ink cartridge for the inkjet printer with the ink cartridge holding part, for example, the commonly used ways are snap fit and buckle fit. For example, as shown in Figure 30 of Chinese patent CN201510060960.1, the ink cartridge is fixed by engaging the first device-side engaging portion on the movable lever of the printer holding portion with the first ink cartridge-side engaging portion of the ink cartridge. When the ink cartridge needs to be taken out, The first ink cartridge side engagement portion of the ink cartridge is disengaged from the first device side engagement portion by pushing the push portion of the movable lever, so that the ink cartridge can be taken out from the holding portion. However, there are some technical problems in such a joining method.

In the first aspect, since the rotation axis of the movable lever is located between the push part and the joint part on the first device side, the record between the joint part on the first device side and the rotation shaft is d, and the distance between the push part and the rotation shaft is The distance is t. On the basis of this structure, in order to keep the ink cartridge and printer miniaturized, the size of the movable lever needs to be reduced, and there will be a situation where d≥t. When taking out the ink cartridge, according to the principle of moment balance, it needs to act on the push part The upper force is relatively large, so it will be difficult to remove.

In the second aspect, in the process of taking out the ink cartridge, the lever needs to be rotated counterclockwise, and the joint part on the first device side will move in the direction of the -Z axis while rotating counterclockwise, so that the ink cartridge must first move down before the second device can be moved. A cartridge-side engaging portion is disengaged from the first device-side engaging portion. This method can cause damage to the stylus or the chip. The -Z-axis direction we refer to here refers to the direction in which the other surface opposite to the plane where the ink outlet is located points to the plane where the ink outlet is located. In order for the ink cartridge to be taken out smoothly, the ink cartridge must retain a certain -Z axis space, which is not conducive to the miniaturization of the ink cartridge and the printer. At the same time, because the ink cartridge retains the space in the -Z axis direction, the ink outlet and the If the ink tube of the retainer is not tightly sealed, it will cause ink leakage.

In the third aspect, since the ink cartridge must move in the -Z axis direction before the ink cartridge is taken out, the pressing force of the ink cartridge on the elastic contact pin of the ink cartridge holding part is greater. When the ink cartridge is taken out, due to the elastic contact pin giving The elastic force of the ink cartridge is too large, causing the ink cartridge to bounce high from the ink cartridge holder, which may cause the ink outlet to break away from the bottom of the ink cartridge holder, causing ink to splash out at the ink outlet, staining the ink cartridge holder, the printer, and the printer. or countertop.

In the fourth aspect, the distance between the first ink box side joint and the second ink box side joint is very close on the Z axis, and it is easy to form a joint that passes through the first ink box side joint and the second ink box side joint and is perpendicular to the YZ plane. A rotation axis, at the same time, the moving direction of the ink cartridge holding part in the printing process of the printer is the Y-axis direction. During the movement of the ink cartridge holding part, the ink cartridge is subject to a force in the Y-axis direction given by the flowing air, so that the ink cartridge may Shaking around the axis of rotation perpendicular to the YZ plane occurs, which in turn causes unstable fixing of the ink cartridge, poor contact of the chip or poor sealing of the ink outlet.

At present, there is no technical solution capable of solving the above-mentioned problems.
