Definitions

  • the present utility model relates to an ink cartridge with ink tanks for an inkjet printer.
  • the first type is one using a sponge to store ink and controlling the printing with the capillary effect of the sponge. After the ink cartridge is used out, too much ink remains in the sponge, which causes a waste of ink, and is not environment-friendly, and also increases the cost.
  • the other type is a spongeless method, which uses a complicated design of an air intake system and a complicated ink cartridge structure, and thus includes too many parts and requires complex processes. Also, due to the height of the negative pressure control value being disposed and the design of the ink path, too much ink will be left.
  • the present invention is directed to provide an ink cartridge with ink tanks for a printer, which comprises a bottom case, a cover, and ink tanks. Inks are classified and stored into independent ink tanks, which is assembled in the bottom case. Each of the ink tanks includes a negative pressure mechanism for controlling a flow rate of the ink. Soft films are welded on both sides of an ink tank support, the inks are stored between the soft films, and a volume between the soft films is variable. During printing, with the consumption of the inks, the volume becomes smaller. The inks flow into an inkjet cavity through a one-way valve. A seal ring, a one-way valve core, and a spring are disposed at an ink outlet port below the inkjet cavity.
  • the ink tank does not have an air intake system, such that the air will not get into the ink tanks, and is isolated from the inks to prevent bubbles entering the ink outlet port.
  • the printing performance is stable and reliable, and the printing quality is improved.
  • FIG. 1 is a stereogram of the internal structure of an ink cartridge according to an embodiment of the present invention.
  • FIG. 2 is a schematic structural view of the ink tanks according to an embodiment of the present invention.
  • FIG. 3 is a schematic view of the leakage prevention mechanism of the ink tanks according to an embodiment of the present invention.
  • the present invention includes a bottom case 2, a cover 1, and an ink tank support 3.
  • Each color of ink is stored in an independent ink tank.
  • the ink tank includes a negative pressure mechanism, which is composed of a valve spring 4, a valve diaphragm 5, and a valve domed cap 6.
  • Soft films 7 are welded on both sides of the ink tank support, and inks are stored in an ink storage cavity 11.
  • the ink storage cavity 11 is formed by the ink tank support 3 and the soft films 7, and has a variable volume. During printing, with the consumption of the inks, the volume of the ink storage cavity becomes smaller. The inks in the ink storage cavity 11 flow into the negative pressure mechanism through an ink path 12, then flow into an inkjet cavity 13, and finally get into an ink outlet port 14.
  • the ink outlet port of the ink tank includes a leakage prevention mechanism, which is composed of an ink outlet port spring 8, a valve core 9, and a seal ring 10.
