Abstract
The utility model relates to a Ink box including a body which has an ink cavity, a cover to seal the outlet of the body, an ink outlet to provide ink in the ink cavity to the printing device; an air inlet on the cover communicating with outside atmosphere by a bending guide channel , an ink buffer cavity forming a part of the air guide channel, wherein, the ink buffer cavity is positioned in the inner side of the cover of the body. It has the advantages of simple structure , anti-overflow of ink.
Description
Technical field
The utility model relates to a kind of print cartridge that ink-jet printer is used.
Background technology
Print cartridge generally includes the black chamber that holds ink, to the ink supply port of ink-jet printer ink supply and atmosphere is imported the gas port in black chamber.During printing, with the minimizing of ink in the inking chamber, the air outside the black chamber is mended into black chamber by gas port, and the pressure equilibrium with inside and outside the maintenance print cartridge makes ink supply normal.
CN1197707 C Chinese invention patent discloses a kind of print cartridge, and air inlet is located on the print cartridge cover, and an end is communicated with black chamber, and the elongated slot of the complications of the other end by being formed at the cover surface, a upright opening and a recess that is located on the cover are communicated with atmosphere.Its center dant is covered by the film that one deck easily punctures, and when print cartridge was mounted to printer, this film was printed the pin of one on the machine and punctures, and atmosphere is able to mend into black chamber through air inlet along the elongated slot of recess, upright opening, complications.
Recess and upright opening with its cover of print cartridge of said structure are located at an end that connects atmosphere, in the placement or use of print cartridge in the long period, because the variation of capillarity and external environmental condition has a spot of ink that the elongated slot from air inlet along complications is entered in upright opening and the recess inevitably.But,, cause client's the loss and the pollution of environment so the ink that stockpiles in it directly spills into the print cartridge outside easily because of recess is pierced not sealing of back at the film of its surface coverage.
Summary of the invention
Main purpose of the present utility model provides a kind of black print cartridge that overflows that prevents.
For achieving the above object, the print cartridge that the utility model provides comprises a box body, has the black chamber that holds ink; Seal the cap of described box opening; With the ink outlet port of the ink feed in the black chamber to printing equipment; The air inlet that is positioned at cap and black chamber is communicated with atmosphere by an air guide channel that bends; At least constitute the black liquid cushion chamber of an air guide channel part, its China and Mexico's liquid cushion chamber is positioned at the inboard of box body cap.
According to the print cartridge of above scheme, the ink that overflows in the black chamber can at first be temporarily stored in the black liquid cushion chamber, but because of black liquid cushion chamber is sealed by the print cartridge cover, so ink can directly not overflow to the print cartridge outside.
Scheme is that black liquid cushion chamber is positioned at the end that air guide channel links to each other with black chamber preferably.
Better scheme is that black liquid cushion chamber is provided with a diapire, and along the gas flow direction in the black liquid cushion chamber, diapire is with respect to the downward-sloping setting of cap.
According to the print cartridge of above scheme, the ink that stockpiles of black liquid cushion chamber can flow back to black chamber along downward-sloping diapire under the gravity effect of self, prevent that effectively ink is excessive.
Another better scheme is that black liquid cushion chamber is built-in with the porosity and looseness medium.
According to the print cartridge of above scheme, the ink that stockpiles in the black liquid cushion chamber can effectively be adsorbed by the porosity and looseness material, has further reduced the excessive possibility of ink.
Description of drawings
Fig. 1 is the assembling schematic diagram of the utility model first embodiment print cartridge;
Fig. 2 is the cap structural representation of the utility model first embodiment print cartridge;
Fig. 3 is the cap structural representation of the utility model second embodiment print cartridge.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples.
First embodiment:
Referring to Fig. 1, print cartridge 1 is made up of the cap 3 of a rectangular substantially box body 2 and sealing box body 2 openings.There is the black chamber 4 that holds ink the inside of box body 2, and the bottom has one with the ink outlet port 5 of the ink feed in the black chamber 4 to printing equipment, is provided with sealing ring 6 in the ink outlet port 5, and diaphragm seal 7 is posted with sealing ink outlet port 5 in the outside.
Referring to Fig. 2, along the Atmospheric Flow direction (arrow B) in the black liquid cushion chamber, the diapire 15 of China ink liquid cushion chamber 12 is with respect to cap 3 downward-sloping settings, makes the communicate diapire 15 of an end of black liquid cushion chamber 12 and black chamber 4 be lower than the diapire 15 of its end that links to each other with air inlet 9.After ink enters black liquid cushion chamber 12 like this, understand the effect because of himself gravity, 14 flow back into black chamber 4 along diapire 15 from opening, prevent that ink from overflowing from air inlet 9.
When using print cartridge, need at first partially torn air guide film 16, the part of the groove 11 of bending is exposed in the atmosphere, thereby makes ambient atmosphere, mend black chamber 4 through groove 11, air inlet 9, the black liquid cushion chamber 12 of bending along arrow A, B, C.In this process, the groove 11 of bending, air inlet 9, the black liquid cushion chamber 12 common air guide channels that form.
Excessive in order better to prevent ink, black liquid cushion chamber 12 is separated into two parts 12a, 12b by dividing plate 17, and placing porous porous medium 18 in the 12a that communicates with black chamber 4 part is as sponge etc.In placement of 1 long period of print cartridge or use, owing to capillarity or external environment condition change when causing ink to overflow into black liquid cushion chamber 12, porosity and looseness medium 18 is adsorbable basically to fall excessive ink, prevents that the inks in the black liquid cushion chamber 12 from further overflowing to air inlet 9 places.
Second embodiment:
Fig. 3 illustrates the cap 3 of second embodiment of the present invention print cartridge.
What present embodiment was different with first embodiment is that black liquid cushion chamber 12 is divided into 12a, 12b, 12c, 12d four parts, partly reaches the 12c part alternate with 12a at the 12a that communicates with black chamber and is placed with the first porosity and looseness medium 18a and the second porosity and looseness medium 18b respectively.When ink overflows in the black liquid cushion chamber 12, basically can be by the first porosity and looseness medium 18a absorption of 12a part, even there is the small part ink to continue to overflow into the 12c part, also can have been prevented the generation of the excessive phenomenon of ink effectively by second porosity and looseness medium 18b absorption.
Variation based on the utility model design is not limited in the foregoing description, also multiple variation can be arranged, and as being separated into three parts in the black liquid cushion chamber, also available in addition waterproof ventilative material such as waterproof and breathable plug etc. replace the porosity and looseness medium.The effect that they are obtained is identical.These simple structural changes still belong to the protection domain of the utility model requirement.
