Abstract
The utility model relates to a printer ink box which is in a constant pressure-type and is environment protection and comprises an ink box shell and a surface cover; the shell is provided with at least one chamber for storing ink inside; the lower part of the shell is provided with an ink feed orifice which is connected with the printer; the surface cover is provided with a vent and an ink adding orifice which is communicated with the chamber of the storing ink; the vent is communicated with an air flue inside the shell; and the air flue is arranged inside the ink box shell and extends along the side of the shell to an air inlet at the bottom of the chamber of the storing ink; the utility model is characterized in that the channel inside the ink feed orifice is provided with a filtering screen; the filtering face of the filter screen is toward vertically to the bottom; and the ink goes through the filter screen from the bottom to the top. As the filter screen is arranged on the ink feed channel, and the filtering face is toward vertically to the bottom, the impurities accumulated on the filtering screen automatically break off from the filtering screen due to the self weight, and the sediment can not be formed, so as to guarantee the normal utilization of the printer.
Description
Technical field
The utility model relates to a kind of ink-jet printer consumptive material, and especially a kind of air pressure principle adjustment print cartridge that utilizes goes out China ink, and can add the reusable ink-cases of printers of ink.
Background technology
The constant voltage ink-cases of printers is an air pressure balance ink weight of utilizing print cartridge inside, thereby make ink continue to feed the novel print cartridge of printer ink-providing mouth, compare with existing other types print cartridge, its print quality is higher, installs simply cheap during ink memory space Datong District.But still there is a defective in existing constant pressure type ink-cases of printers, owing to must also have certain granule foreign in the ink, so usually filter paper or filter screen need be set at the ink supply port place, stops up printer head to avoid the impurity in the ink.Because filter screen is arranged on the top of ink supply port, ink is from top to down by filter screen, so after long-time the use, granule foreign will be deposited in filter screen
Summary of the invention
Easily deposit impurity on the long-time use back filter screen that the purpose of this utility model is to exist at existing print cartridge, thereby influence the normal deficiency of using of printer, provide a kind of and the novel constant voltage environmental protection ink-cases of printers of position to address the above problem be set by what adjust filter screen.
Technical solution of the present utility model is: a kind of constant pressure type environmental protection ink-cases of printers, comprise cartridge case and cover, enclosure interior is provided with the chamber of at least one storage ink, the ink supply port that the lower part of frame setting is connected with printer, cover is provided with a passage and an ink adds the hole, ink adds the hole and is connected with the chamber of storage ink, the passage air flue interior with being arranged on housing is connected, this air flue is extended to the air admission hole of the cavity bottom of storage ink along the sidewall of housing by top in cartridge case, it is characterized in that: the passage that ink enters ink supply port is provided with filter screen, and the filtering surface of filter screen is towards vertical below, and ink passes through filter screen from bottom to top.
The beneficial effects of the utility model are: because filter screen is arranged on the ink-feed channel, and filtering surface is towards vertical below, therefore be deposited on the filter screen impurity since the gravity of self can come off from filter screen automatically, and can not form deposition, thereby guaranteed the normal use of printer.

The specific embodiment
Specific embodiment of the utility model as shown in Figures 1 to 4, a kind of constant pressure type environmental protection ink-cases of printers, comprise cartridge case 1 and cover 2, enclosure interior is provided with the chamber of at least one storage ink, the ink supply port 8 that the lower part of frame setting is connected with printer, cover 2 is provided with a passage 3 and an ink adds hole 4, ink adds hole 4 and is connected with the chamber of storage ink, passage 3 air flue 5 interior with being arranged on housing is connected, this air flue is extended to the air admission hole 6 of the cavity bottom of storage ink along the sidewall of housing by top in cartridge case, the passage 7 that ink enters ink supply port 8 is provided with filter screen 10, and the filtering surface of filter screen 10 is towards vertical below, and ink is from bottom to top by filter screen 10.
During use, at first open the passage 3 on the print cartridge cover 2, and the airway unobstructed in the assurance housing, the printer of then print cartridge being packed into, the ink supply pin of printer passes sealing ring 16 and Packing spring 14, back down needle seal 15, ink is entered by ink-feeding hole 9, and filters by filter screen 10, flows through into ink passage subsequently, enter ink supply port 8, print cartridge begins to be printer ink-providing.When the ink in the print cartridge just forms a vacuum area 17 in the chamber top when water level reduces along with use, at this moment, because extraneous air pressure is greater than storage film chamber interior air pressure, so air constantly enters, and forms stable ink pressure at inkjet mouth.After ink used, the user opened the sealing-plug that ink adds the hole, adds suitable ink, sealing-plug is installed just subsequently again and can reuse.
On the ink flow line of print cartridge, also be provided with diaphragm seal 11, diaphragm seal 12, diaphragm seal 13 and diaphragm seal 18.
