Definitions

  • the present invention relates to an ink cartridge. More particularly, the present invention relates to an ink cartridge having flow channels fabricated separately by means of module and then assembled to the body.
  • Inkjet printing technique has been widely used in office equipment having the function of printing graphics. Inkjet printing technique mainly uses a high pressure produced by a printhead (inkjet chip) to push ink instantly. Ink drops are then jetted from the printhead onto a surface of a document so as to form ink dots which form graphics or texts on the surface of the document.
  • a printhead inkjet chip
  • the ink cartridge In order to supply ink to the printhead, the ink cartridge has an ink chamber for storing ink and a flow channel for guiding the ink in the ink chamber to the printhead.
  • the ink of each color has an independent ink chamber and an independent flow channel.
  • Taiwan Patent No. I259806 entitled “Ink Cartridge” has disclosed a technique of fabricating the ink chambers and the flow channels of the ink cartridge separately and then assembling them, which facilitates reducing the fabricating cost of the ink cartridge.

  • the body 110 has three ink chambers 112a, 112b, and 112c and three ink delivery ports 116a, 116b, and 116c.
  • the ink delivery ports 116a, 116b, and 116c are located at the bottom of the body 110, and the ink chambers 112a, 112b, and 112c respectively fluidly communicate with the ink delivery ports 116a, 116b, and 116c, so that the ink in the ink chambers 112a, 112b, and 112c is supplied to the channel module 120.
  • the channel module 120 has three flow channels 122a, 122b, and 122c.
  • the ink chambers 112a, 112b, and 112c respectively fluidly communicate to the flow channels 122a, 122b, and 122c by the ink delivery ports 116a, 116b, and 116c on the bottom.
  • the flow channels 122a, 122b, and 122c further respectively have three ink supply ports 124a, 124b, and 124c in a chip bonding area R, such that the ink is output to the printhead (inkjet chip) on the chip bonding area R.
  • the channel module 120 is attached to the bottom of the body 110 by means of ultrasonic welding, laser welding, or adhesive coating. No matter before or after the attaching, in order to locate the channel module 120 onto the bottom of the body 110, two blocks 118a and 118b of the body 110 are respectively engaged with two indentations 128a and 128b of the channel module 120, such that the channel module 120 is located at the bottom of the body 110.
  • the blocks 118a and 118b and the indentations 128a and 128b to locate the body 110 and the channel module 120, only one side (adjacent to the left side of FIG. 1B, or referred to as the front end of the channel module 120) of the channel module 120 can be located, and the other side of the channel module 120 (adjacent to the right side of FIG. 1B, or referred to as the back end of the channel module 120) can move or swing. Therefore, whether the location is accurate after assembling has to be inspected by a measurement tool with at least a two-dimensional level. If the swing is serious, the attachment between the channel module 120 and the body 110 is poor. Therefore, in order to prevent the swing of the channel module 120, one method is to fit the blocks 118a and 118b with the indentations 128a and 128b by means of an interference fit.

  • the engaging parts 640a to 640c are indentations, the engaging parts on the body (not shown) corresponding to the engaging parts 640a to 640c are blocks, and vice versa.
  • the number of the above engaging parts on the channel module and the body are determined according to the design requirement, and are respectively located at the corresponding position of the body and the channel module, so as to fix the relative position of the body and the channel module on the two-dimension plane.
  • the location of the engaging part on the channel module is not limited to any one side edge of the channel module, and can also be formed on the lower surface of the channel module attached to the bottom of the body.
  • FIG 6 is a perspective exploded view of an ink cartridge according to a sixth embodiment of the present invention.
  • engaging parts 730a to 730d are at four corners of the external surface of the bottom 750 of the body 710 of the ink cartridge 700, and are engaged with the engaging parts 740a to 740d at four corners of the channel module 720.
  • the engaging parts 730c and 730d of the ink cartridge 700 are indentations instead, and the engaging parts 740c and 740d thereof are blocks instead.
  • FIG 7 is a perspective exploded view of an ink cartridge according to a seventh embodiment of the present invention.
  • an engaging part 830 is on the external surface of the bottom 850 of the body 810 of the ink cartridge 800 in the seventh embodiment and partially surrounds the side edges of the channel module 820, such that the relative position of the body 810 and the channel module 820 on a two-dimension plane (XY plane) is substantially fixed by the engagement of the engaging part 830 and the channel module 820.
  • XY plane two-dimension plane
  • FIG 8 is a perspective exploded view of an ink cartridge according to an eighth embodiment of the present invention.
  • an engaging part 930 is arranged on the external surface of the bottom 950 of the body 910 of the ink cartridge 900 in the eighth embodiment and fully surrounds the side edges of the channel module 920, such that the relative position of the body 910 and the channel module 920 on a two-dimension plane (XY plane) is substantially fixed by the engagement of the engaging part 930 and the channel module 920.
  • XY plane two-dimension plane
  • the ink cartridge of the present invention uses the engagement to ensure the accuracy and liability of the location between the body and the channel module.
  • the horizontal section of some flow channels extend from the chip bonding area to an area outside the chip bonding area, thereby improving the flexibility in arrangement of the ink chambers.
