Abstract

A refillable ink box proofed against the formation of airlocks during filling includes an ink storage chamber, a seat, and an insertion tube. The box includes a bottom plate, and first and second side walls. The bottom plate and first and second side walls form the ink storage chamber. The seat protrudes to the exterior and carries insertion tube, ink outlet, and air guiding port. The insertion tube defines the ink inlet and also an air vent. The ink inlet communicates with the ink outlet port, the ink outlet communicates with the ink storage chamber. The air guiding port equalizes gas pressure with outside atmosphere and is positioned above the ink outlet.

First claim

What is claimed is:

1. An ink box comprising:
an ink storage room comprising a bottom plate, a first side wall and a second side wall; the first side wall and the second side wall both fixed to the bottom plate, the second side wall connected to two ends of the first side wall; the bottom plate, the first side wall and the second side wall together forming an ink storage chamber;
a seat fixed to the bottom plate and protruding from an outside of the first side wall, the seat defining an ink outlet and an air guiding port;
an insertion tube fixed to the seat and used for inserting an ink bottle, a side of the insertion tube forming an ink inlet and an air vent, the ink inlet being located above the air vent and at least a predetermined distance from an end of the insertion tube away from the seat, the ink inlet communicating with the ink outlet port, the ink outlet communicating with the ink storage chamber, the air guiding port communicating with the air vent and outside atmosphere, the air guiding port positioned above the ink outlet; and
a third side wall fixed to the bottom plate, and fixed to the first side wall and the second side wall to form a receiving cavity;
wherein the second side wall defines a first ink channel, the first ink channel comprises a first inlet and a first outlet communicating with the first inlet, a distance between the first inlet and the bottom plate is greater than a distance between the first outlet and the bottom plate, the first inlet communicates with the ink storage chamber, and the first outlet communicates with the receiving cavity such that when the ink in the ink storage room is located at the first inlet, the first ink channel guides ink into the receiving cavity, and at least one fourth side wall extending from an inner side of the third side wall to the seat, the at least one fourth side wall dividing the receiving cavity into a number of adjacent accommodating regions, the accommodating areas communicating with each other.

2. The ink box of claim 1 , wherein an ink outlet tube is fixed to an outer side of the first side wall and communicates with the ink storage chamber.

3. The ink box of claim 1 , wherein the predetermined distance is thirty centimeters.

4. The ink box of claim 1 , wherein the ink box comprises four fourth side walls, and the four fourth sidewalls divide the receiving cavity into five accommodating regions.

5. The ink box of claim 4 , further comprising:
a sealing member fixed on end surfaces of the first side wall, the second side wall, the third side wall and the fourth side wall away from the bottom plate.

6. The ink box of claim 5 , wherein the sealing member is a heat-pressed thin film fixed to the end surfaces.

7. The ink box of claim 5 , wherein an end of the first side wall away from the bottom plate defines a through hole, the outside atmosphere flows into the receiving cavity and the ink storage chamber through the through hole to enter to the air guiding port.

8. The ink box of claim 1 , wherein each fourth side walls define a second ink channel, each second ink channel comprises a second inlet and a second outlet communicating with the second inlet, each second inlet communicates with one of the accommodating regions, and each second outlet communicates with another adjacent accommodating region.

9. An ink box comprising:
an ink storage room comprising a bottom plate, a first side wall and a second side wall; the first side wall and the second side wall both fixed to the bottom plate to form an ink storage chamber;
a seat connected to the bottom plate and protruding from an outside of the first side wall, the seat defining an ink outlet and an air guiding port;
an insertion tube connected to the seat and used for inserting an ink bottle, the insertion tube defining an ink inlet and an air vent, the ink inlet being located above the air vent and a predetermined distance from an end of the insertion tube away from the seat, the ink inlet communicating with the ink outlet port, the ink outlet communicating with the ink storage chamber, the air guiding port communicating with the air vent and outside atmosphere, a distance between the air guiding port and the insertion tube being closer than a distance between the ink outlet and the insertion tube; and
a third side wall fixed to the bottom plate, and fixed to the first side wall and the second side wall to form a receiving cavity;
wherein the second side wall defines a first ink channel, the first ink channel comprises a first inlet and a first outlet communicating with the first inlet, a distance between the first inlet and the bottom plate is greater than a distance between the first outlet and the bottom plate, the first inlet communicates with the ink storage chamber, and the first outlet communicates with the receiving cavity, such that when the ink in the ink storage room is located at the first inlet, the first ink channel guides ink into the receiving cavity, and at least one fourth side wall extending from an inner side of the third side wall to the seat, the at least one fourth side wall dividing the receiving cavity into a number of adjacent accommodating regions, the accommodating areas communicating with each other.

10. The ink box of claim 9 , wherein an ink outlet tube is fixed to an outer side of the first side wall and communicates with the ink storage chamber.

11. The ink box of claim 9 , wherein the predetermined distance is thirty centimeters.

12. The ink box of claim 9 , wherein the ink box comprises four fourth side walls, and the four fourth sidewalls divide the receiving cavity into five accommodating regions.

13. The ink box of claim 12 , further comprising:
a sealing member fixed on end surfaces of the first side wall, the second side wall, the third side wall and the fourth side wall away from the bottom plate.

14. The ink box of claim 13 , wherein the sealing member is a heat-pressed thin film fixed to the end surfaces.

15. The ink box of claim 13 , wherein an end of the first side wall away from the bottom plate defines a through hole, the outside atmosphere flows into the receiving cavity and the ink storage chamber through the through hole to enter to the air guiding port.

16. The ink box of claim 9 , wherein each fourth side wall defines a second ink channel, each the second ink channel comprises a second inlet and a second outlet communicating with the second inlet, each second inlet communicates with one of the accommodating regions, and each second outlet communicates with another adjacent accommodating region.
