Abstract
The invention discloses an ink supply channel structure in an inkjet head chip. The ink supply channel structure in the inkjet head chip comprises a box used for containing ink, an outlet formed in the bottom of the box, and a sealing device mounted on the upper surface of the box. By adoption of the ink supply channel structure, it is guaranteed that ink is smooth in the printing state, and thus the smoothness of the ink in the printing state can be improved. A balancing device is arranged on an upper cover plate, so that the air pressure in the ink supply channel structure in the inkjet head chip and the air pressure outside the ink supply channel structure in the inkjet head chip are balanced all the time, and ink leakage caused by excessively-high air pressure in the printing state is avoided accordingly.
Description
Technical field
This
Invention
It is related to a kind of being applied on printer
Ink supply flow passage structure in chip of ink-jet head
。
Background technology
Print cartridge that is various disposable in existing market sale or can using again, its most of print cartridge is all to include casing, be arranged at the water flowing out structure of bottom half and be installed on the upper cover plate on casing top.When printing, constitute because of the single cavity volume that box house cavity volume is formed in one so that it is contained in the streamline of the output of the ink inside cavity volume in a kind of discontinuous state, cause its whole described ink in print state often in not fluency.
The content of the invention
The present invention provides a kind of fluency that not only can improve the ink in print state to solve the technical problem of above-mentioned prior art presence, but also can avoid the ink supply flow passage structure under print state in the chip of ink-jet head of the generation of the phenomenon of ink leakage.
For achieving the above object, ink supply flow passage structure in a kind of chip of ink-jet head provided by the present invention, it is included for the casing equipped with ink, the outlet for being installed on bottom half and the sealing device being installed on above casing, separation panel is provided with casing, on the separation panel ink port is opened up；The bascule for buffering tray interior pressure is provided with the upper cover plate.
According to above-mentioned technical characteristics, the rectangular body of described casing, the inking chamber for housing ink is offered inside the cuboid, middle position in the inking chamber is provided with the separation panel that inking chamber is separated into left and right cavity volume, the bottom of the separation panel is provided with ink port, water transport structure is installed in the bottom of the ink port；The bottom of casing is provided with a connector, in the side of casing an elastic pinch plate is extended, on the elastic pinch plate buckle slot is offered；The opposite side of casing extends a buckle plate body, and the lower surface of the buckle plate body is provided with the first buckle post, the bottom of the buckle plate body is provided with the chip slot for chip, and the lower end in the chip slot is provided with the second buckle post；The bottom of chip slot is provided with rectangular channel.
According to above-mentioned technical characteristics, the rectangular plate body of described upper cover plate, one end of rectangular panel body is provided with bascule, the two ends of the bascule are respectively arranged with left and right valve guard；The other end of the rectangular panel body is provided with the plug hole for installing plug, left and right plug baffle plate is provided with the position at the plug hole two ends；The buckling body of extended spot one above the rectangular panel body of bascule one end is being provided with, card convex body should be provided with above the buckling body；The middle position of upper cover plate is provided with middle baffle plate.
The Advantageous Effects of the present invention：Because being provided with separation panel in casing, ink port is opened up on the separation panel, so that it is in print state, air pressure in the left and right cavity volume in casing is kept to be completely in vacuum state, so as to ensure that ink during print state under flow, therefore can reach the fluency for improving the ink in print state.Bascule is set on upper cover plate so that its available buffer or reduce print state ink gas pressure, so as to avoid under print state because gas it is excessive cause the phenomenon of ink leakage to occur.
It is have further understanding to the purpose of the present invention, structural feature and its function, hereby coordinates accompanying drawing to describe in detail as follows：
【Description of the drawings】
Fig. 1 is a kind of stereogram of the ink supply flow passage structure in the present invention in chip of ink-jet head；
Fig. 2 is the stereogram of the upper cover plate in the present invention；
Fig. 3 is the schematic partial cross-sectional view of the casing in the present invention.
【Specific embodiment】
Refer to shown in Fig. 1 to Fig. 3, the ink supply flow passage structure in a kind of chip of ink-jet head provided by the present invention is illustrated with reference to embodiment, it includes for the casing 1 equipped with ink, is installed on the outlet of the bottom of casing 1（It is not drawn into figure）And the sealing device 2 being installed on above casing 1.
The described rectangular body of casing 1, the inking chamber for housing ink is offered inside the cuboid, middle position in the inking chamber is provided with the separation panel 13 that inking chamber is separated into left and right cavity volume 11,12, the bottom of the separation panel 13 is provided with ink port 14, water transport structure is installed in the bottom of the ink port 14；The bottom of casing 1 is provided with a connector 15, in the side of casing 1 elastic pinch plate 16 is extended, on the elastic pinch plate 16 buckle slot 17 is offered；The opposite side of casing 1 extends a buckle plate body 18, and the lower surface of the buckle plate body 18 is provided with the first buckle post 19, the bottom of the buckle plate body 18 is provided with the chip slot 10 for chip, and the lower end in the chip slot 10 is provided with the second buckle post 101；The bottom of the chip slot 10 is provided with rectangular channel 102.
The described rectangular plate body of upper cover plate 2, in one end of rectangular panel body bascule 21 is provided with, and the two ends of the bascule 21 are respectively arranged with left and right valve guard 22,23；The other end of the rectangular panel body is provided with the plug hole 24 for installing plug, left and right plug baffle plate 25,26 is provided with the position at the two ends of plug hole 24；The buckling body 27 of extended spot one above the rectangular panel body of the one end of bascule 21 is being provided with, card convex body 28 should be provided with above the buckling body 27；The middle position of upper cover plate 2 is provided with middle baffle plate 29.
