- the retarding member is an elastic member that cooperates with the first sealing portion.
- the elastic member is a coil spring 19.
- the ink cartridge filling device of the above structure is used to carry out ink When the ink is injected, that is, when the cover member 15 is rotated clockwise around the shaft, the spring 19 is compressed to generate a compressive force to urge the first sealing portion to closely fit with the air inlet 23; and when the ink filling is completed, the cover member 15 is wound around the shaft When the counterclockwise rotation causes the second sealing portion to open the intake passage 12, the first sealing portion remains in the state of sealing the intake port 23, and only when the cover member 15 is rotated to a certain angle, the spring 19 follows the cover member.
- the movement of 15 moves upward so that its compressive force is canceled, and the first seal portion is disengaged from the intake port 23.
- a certain negative pressure remains in the ink cartridge 2, but it is not a large negative pressure, which can promote the ink in the sponge 211 and the cotton core 221, and can also ensure the ink. It is not oversaturated to prevent dripping.
- the structure of the first sealing portion in the above process description may be the first elastic pad, the protruding portion and the elastic sleeve, or other similar sealing members, and the list is not mentioned here. More description.
- the ink cartridge may also be an ink-free chamber, and only the sponge cartridge is loaded, that is, the filling device and the filling method are also suitable for filling the ink cartridge.
- the number of the extension hooks may be one or more than two, and the position and number of the slots correspond to the extension hooks.
- cover member can also move up and down in parallel with respect to the ink cartridge positioning mechanism.
- the cover member and the ink cartridge positioning mechanism can also be connected to each other by extending the cooperation of the hook and the card slot. .
- sealing or opening action of the first sealing component and the second sealing component on the cover member can be simultaneously performed, that is, the sealing of the opening and the elimination of the sealing of the ink cartridge after the ink filling are performed simultaneously. This only causes more of the ink in the sponge to flow back into the ink container, which also prevents ink drop.
- the ink cartridge filling device can also be made of an opaque material, so that when ink is injected, it can be judged that the ink cartridge is full when the ink is seen in the aspirator, and thus, only It is necessary to refill the excess ink in the aspirator into the ink container after the ink is injected.
- the ink container and the ink cartridge are placed in a pressure unbalance state during ink replenishment, so that the pressure balance is restored after the ink is injected, that is, the action of injecting the ink into the ink cartridge and replenishing the air to the ink container.
- the action is not performed at the same time. In this way, the excess ink of the sponge and the cotton core in the ink cartridge can be removed to prevent the ink drop phenomenon.
