Description

The print cartridge of tubular ink-sucking port

Affiliated technical field

The utility model relates to printer, relates in particular to the print cartridge of ink-jet printer.

Background technology

The employed print cartridge of present ink-jet printer is built-in with an elasticity mandruka, and marking ink is adsorbed wherein.In printer when work,, the suction function that utilizes ink gun by being arranged on the ink-sucking port in the print cartridge bottom, is drawn the ink in the sponge with the ink in the sponge, again through ink outlet port with the ink sucking-off, realize inkjet printing.In order to guarantee to draw the reliable of ink, usually ink-sucking port is made oval shape, with the contact area of increase with sponge.But the unfavorable factor of bringing is because ink-sucking port is big and exceed the print cartridge bottom surface, often can not be formed the space by sponge wrapping around the ink-sucking port, air trapping makes that air is clipped in the ink when printing blotting in the space, cause out China ink discontinuous, influence print quality.

The utility model content

The utility model has overcome shortcoming of the prior art, and a kind of print cartridge of tubular ink-sucking port is provided.

In order to solve the problems of the technologies described above, the print cartridge of tubular ink-sucking port, comprise cartridge body that is shaped on ink outlet port and the ink box cover that seals cartridge body, projection one plane, bottom surface of cartridge body, ink-feeding tube is arranged on the plane of projection, and the lower end of ink-feeding tube communicates with ink outlet port, and the upper end is an ink-sucking port, the ink-feeding tube outer surface be shaped as up-small and down-big truncated cone-shaped or cylindrical, on the plane of projection, the next door of ink-feeding tube is shaped on the recessed air pit of depositing.

Cartridge body according to such scheme is made because ink-sucking port is tubular, therefore has following advantage:

1, in sponge cartridge is arranged, though the contact area that tubular ink-sucking port and sponge prolong is big not as good as oval shape, ink-sucking port can be inserted into the middle part of sponge, can guarantee that blotting is reliable, and can make ink-sucking port on every side by sponge wrapping, be not easy around ink tube, to form the space.Simultaneously, ink tube is arranged on the raised surface of print cartridge bottom surface, and the next door also has the recessed air pit of depositing, even upwards also can make air leave recessed depositing in the air pit in when print cartridge bottom surface in carrying, away from ink outlet port, guarantees print quality.

2, in sponge-free ink box; since the ink-feeding tube outer surface be shaped as up-small and down-big truncated cone-shaped or cylindrical; when being connected with it with print cartridge pressure equaliser or other ink-feeding devices; can reach and cooperate reliable and sealing; repeat to add ink to print cartridge condition is provided, help environmental protection and reduce the printing cost.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

The print cartridge of tubular ink-sucking port, the cartridge body 2 of ink outlet port 1 and the ink box cover 3 of sealing cartridge body 2 are arranged, cartridge body 2 is boxes of a rectangle, according to what of print cartridge color, cartridge body 2 is separated into corresponding space 5 by dividing plate 4, ink box cover 3 seals each space 5 separately, mandruka 6 is housed in the space 5 and pours into the ink of different colours.Bottom protrusion one plane 7 in space 5, its surface vertically is provided with ink-feeding tube 8, and the upper end of ink-feeding tube 8 is an ink-sucking port 9, and ink-sucking port 9 high out-of-planes 7 are at the 5-20 millimeter, and the lower end of ink-feeding tube 8 is an ink outlet port 1, matches with the China ink head of printer.Ink-feeding tube 8 outer surfaces be shaped as up-small and down-big truncated cone-shaped or cylindrical, the next door of ink-feeding tube is shaped on the recessed air pit 10 of depositing on the plane 7 of projection.

The another kind of structure of the print cartridge of tubular ink-sucking port with above-mentioned different be not put mandruka 6 in the print cartridge space 5, but installation print cartridge pressure equaliser 11, its ink supply port cooperates with print cartridge ink-feeding tube 8 intimate of tubular ink-sucking port.The ink-sucking port of print cartridge pressure equaliser 11 is inserted in to be deposited in the air pit 10.

The print cartridge of the tubulose ink-sucking port of making according to such scheme, no matter print cartridge is in the operating position of printing, any position air when still carrying all can not enter ink-sucking port, guarantees print quality.

Claims (4)

1, a kind of print cartridge of tubular ink-sucking port, at least include the cartridge body of ink outlet port and the ink box cover of sealing cartridge body, according to what of print cartridge color, be separated into corresponding space by dividing plate in the cartridge body, be marked with ink in the space, the bottom in each space of cartridge body is provided with ink-feeding tube, the lower end of ink-feeding tube communicates with ink outlet port, the upper end is an ink-sucking port, it is characterized in that, the ink-feeding tube outer surface be shaped as up-small and down-big truncated cone-shaped.
