  • An air inlet opening communicating with the inside and outside of the ink cartridge is also formed.
  • FIG. 9 Chinese utility model patent discloses an ink cartridge overflowing air inlet device, which is provided with two overflow buffer chambers in the interlayer of the ink cartridge cover, the gas enters the first overflow buffer chamber from the top, and then from the second The bottom or side of the overflow buffer chamber enters the cartridge body.
  • a partition plate is disposed between the first and second overflow ink buffer chambers, and the partition plate is provided with through holes so that they communicate with each other.
  • a porous sponge is also placed in the overflow buffer chamber to absorb the overflowed ink.
  • the ink cartridge having the above-mentioned anti-overflow air intake device can prevent ink overflow in the ink cartridge to a certain extent, but the communication hole between the two overflow ink buffer chambers is disposed on the partition plate, and the overflowed ink is not filled with the second overflow.
  • the overflowed ink may flow into the first overflow buffer chamber and overflow from the top of the first overflow buffer chamber.
  • the space of the overflow ink buffer chamber and the adsorption capacity of the porous sponge in the overflow buffer chamber are not good. Summary of the invention
  • the main object of the present invention is to provide an ink cartridge having a good anti-overflow and air guiding effect.
  • a better solution is to place an ink absorbing material in the overflow buffer chamber, which can absorb the overflowed ink and have better anti-overflow effect.
  • Another preferred solution is to place a waterproof and breathable material in the overflow buffer chamber to enhance the resistance to the ink.
  • FIG. 1 is a schematic structural view of an ink cartridge of a first embodiment
  • Figure 2 is a schematic view showing the assembly of the ink cartridge cover of the first embodiment
  • Figure 3 is a plan view showing the cover of the ink cartridge cover of the ink cartridge of the first embodiment
  • Figure 4 is a bottom plan view of the cover of the ink cartridge cover of the ink cartridge of the first embodiment
  • Figure 5 is a schematic view showing the structure of the ink cartridge cover of the ink cartridge of the second embodiment
  • Figure 6 is a schematic view showing the structure of an ink cartridge cover of the ink cartridge of the third embodiment.
  • an ink cartridge 1 includes an ink cartridge body 2 containing ink, and an ink outlet 3 is provided at a lower portion thereof, and a top portion is sealed by a cartridge cover 4.
  • the cover is omitted in each of the figures in this example.
  • the ink cartridge cover 4 includes a cover 41 and a thin member 42.
  • a protruding fence 411 is formed which is higher than the cover body 41.
  • the fence 411 is partitioned into three parts by partitions 412 and 413 to form an ink overflow buffer chamber 51.
  • the thin member 42 may be bonded or thermally welded to the fence 411 to seal the ink overflow buffer chambers 51, 52, 53.
  • the thin member may be a sealing film or a plastic sheet or the like.
  • the air guiding direction of the ink cartridge will be described in detail below with reference to Figs. 3 and 4.
  • the outside atmosphere passes through the meandering air guiding passage 43 provided on the upper surface of the cover body 41, enters the overflow ink buffer chamber 51 from the first air inlet hole 414 in the direction of the arrow a, and then passes through the ink overflow buffer chamber 51 in the directions of arrows b and c.
  • Inner air guiding hole 511, provided in the cover body The channel 416 of the upper surface of the 41, the air guiding hole 521 provided in the ink overflow buffer chamber 52 enters the ink overflow buffer chamber 52, and then passes through the ink overflow buffer chamber 52 in the direction of the arrow (3, e, f, g).
  • the air guiding hole 522, the passage 417 provided on the upper surface of the cover 41, the air guiding holes 531 and 532 provided on the partition 413, the passage 418 provided on the upper surface of the cover 41, and the air guiding hole provided in the overflow buffer chamber 53 533 enters the overflow ink buffer chamber 53, and finally passes through the air guiding hole 534 provided in the ink overflow buffer chamber 53 in the direction of the arrow h, i, the passage 419 provided on the surface of the cover body 41, and the second air inlet provided on the cover body 41.
  • the overflowed ink will flow in the opposite direction to the above-mentioned air guiding direction, that is, first overflow into the overflow ink buffer chamber 53, and then overflow into the overflow ink buffer chamber. 52, 51. Since the communication holes of the three overflow buffer chambers are all communicated through the passage provided on the surface of the cover body 41, only when an overflow ink buffer chamber is filled with ink, the next overflow ink buffer chamber overflows, and the overflow is fully utilized. The space inside the ink buffer cavity effectively prevents the ink from overflowing.
  • the ink adsorbing materials 62, 61 placed in the overflow buffer chambers 51, 53 can also sufficiently exert the absorbing action to further block the ink from flowing out.
  • the structure of the ink cartridge cover 4 of the ink container of this embodiment is substantially the same as that of the first embodiment, wherein the same structure is denoted by the same reference numeral in this embodiment.
  • This embodiment differs from the first embodiment in that a protruding fence 411 is provided on the upper surface of the cover 41, and the middle of the fence 411 is partitioned into three parts by partitions 412, 413 to form an ink overflow buffer chamber 51, 52, 53, wherein Water-repellent and permeable materials 71, 72 are provided in the overflow ink buffer chambers 51, 53.
  • Channels 416, 417, 418 (not shown), 419, which connect the overflow ink buffer chambers 51, 52, 53 and the second air inlet holes 415, are provided on the lower surface of the thin member 42, and the film 8 is attached to the upper surface of the thin member 42. .
  • the structure of the ink cartridge cover 4 of the ink cartridge of this embodiment is substantially the same as that of the first embodiment, wherein the same structure is denoted by the same reference numeral in this embodiment.
  • This embodiment is different from the first embodiment in that the first air inlet hole 414 is provided at the side of the cover body 41, and two different ink adsorbing materials 611, 612, 621 are respectively placed in the ink overflow buffer chambers 51, 53. 622, the film 8 is attached to the upper surface of the thin member 42, forming a part of the channels 416, 417.
  • the ink cartridge of the invention designs a plurality of ink spills on the ink cartridge cover by rationally utilizing the structure of the ink cartridge cover Punching the cavity, arranging different flow channels and placing different leak-proof materials can effectively block the capillary phenomenon of the ink while maximizing the efficiency of the leak-proof material, and well prevent the ink from overflowing.
  • the variation based on the present invention is not limited to the above embodiment, and various changes may be made, such as the first air intake hole being provided on the thin member, or the ink adsorbing material and the waterproof gas permeable material being placed simultaneously in the overflow ink buffer chamber, etc. The effect achieved is the same. These simple structural changes are still within the scope of protection required by the present invention.
  • the overflow ink buffer chamber communicates with the passage provided in the upper portion of the ink cartridge cover, the overflowed ink continues to flow into the next ink overflow buffer chamber only after being filled in an overflow ink buffer chamber. Increased blocking of spilled ink.
