Abstract
The utility model provides an ink cartridge which is provided with an ink conservation device for printer, comprising an ink storing cavity, a pressure adjusting mechanism, a through hole, a surface cover, an air ventilating groove and an isolation material. The pressure adjusting mechanism is communicated with the storing cavity through the through hole. The pressure adjusting mechanism and the through hole are arranged on the bottom of the ink storing cavity. The internal side of the surface cover is provided with the air ventilating groove and the isolation material. The utility model ensures that the ink inside the ink storing cavity flows fully from the ink cut to be used cleanly when the printer is in use, thereby solving the problem of ink survival. Besides, the utility model has the advantages of preventing the ink from overflowing when the ink cartridge is arranged reversely and saving the ink.
Description
Technical field
The utility model relates to a kind of ink-cases of printers that has province's device for ink.
Background technology
Ink-cases of printers is a kind of consumable products commonly used in the modern office equipment.From the existing print cartridge product of existing market (for example Epson T0322), generally there is following shortcoming:
1, higher because of pressure adjustmenting mechanism and lead to the hole site, far away from ink outlet port, can not ink outlet port is clean to the ink printed between pressure adjustmenting mechanism, causing print cartridge to be finished using remainingly in the print cartridge of back has an excess ink, has caused ink waste to a certain extent.
2, in addition, when solving the ink leak problem, the setting that existing print cartridge is taked is too complicated, and the fraud of burden is arranged technically.
The utility model content
The purpose of this utility model provides a kind of band that can solve remaining ink problem and ink leak problem to economize the ink-cases of printers of device for ink with regard to being.
The utility model is achieved in that the utility model comprises ink storage chamber, pressure adjustmenting mechanism, through hole, cover, air channel and barrier material, and the pressure adjustmenting mechanism via through holes communicates with ink storage chamber, and pressure adjustmenting mechanism and through hole are arranged on the bottom of ink storage chamber; The cover inboard is provided with air channel and barrier material.
Pressure adjustmenting mechanism comprises valve body, valve film, dome and spring, the periphery of valve film is sealed between valve body and the dome, the circular hole that one band chimb is arranged on the valve film, this circular hole is set at the inner face that spring between valve body and the valve film withstands on dome, and dome is provided with aperture and communicates with through hole on the storage chamber; The back side of valve body is provided with ink channel and logical black hole.
The cover inboard is provided with air channel, and a part of space of air channel is provided with a barrier material, and the passage on the cover places the end of barrier material.
Barrier material can be sponge or other material that blots.
Advantage of the present utility model is to save ink, on the one hand by pressure adjustmenting mechanism and through hole being arranged on the bottom of ink storage chamber, guarantees that ink can all flow out, and does not have the remaining problem of ink when printing; On the other hand, by the iris action of air channel and the suction function in the ink outlet port, can prevent effectively that ink from flowing out.More than two aspects make the remarkable advantage that the utlity model has economy.

1 ink storage chamber, 2 through holes, 3 ink channels, 31 logical black holes, 4 ink outlet ports, 5 pressure adjustmenting mechanisms, 6 domes, 61 apertures, 7 springs, 8 valve films, 9 air channels, 10 barrier materials, 11 passages, 12 circular holes, 13 covers, 14 valve bodies
The specific embodiment
As shown in the figure, the utility model comprises ink storage chamber 1, pressure adjustmenting mechanism 5, through hole 2, cover 13, air channel 9 and barrier material 10, and pressure adjustmenting mechanism 5 via through holes 2 communicate with ink storage chamber 1, and pressure adjustmenting mechanism 5 and through hole 2 are arranged on the bottom of ink storage chamber 1; Cover 13 inboards are provided with air channel 9 and barrier material 10.
The cover inboard is provided with air channel 9, and a part of space of air channel 9 is provided with a barrier material 10, and the passage 11 on the cover 13 places the end of barrier material 10.
Barrier material 10 can be sponge or other material that blots.
When print cartridge is put into printer for the first time, because the cleaning function of printer self, make and produce certain negative pressure in 5 the space from ink outlet port 4 to pressure adjustmenting mechanism in the ink storage chamber 1 (this space is the sealing shape, and there is through hole 2 that pressure adjustmenting mechanism 5 is communicated with ink storage chamber 1), after printing beginning, ink flows into printhead from the ink channel 3 at pressure adjustmenting mechanism 5 back sides through ink outlet port 4, make from pressure adjustmenting mechanism 5 to ink outlet port 4 pressure reduce, when pressure drops to a certain degree, ink pressure difference in ink pressure in the ink storage chamber 1 and the pressure adjustmenting mechanism 5 is greater than the elastic force of spring 7, the balance of pressure adjustmenting mechanism 5 is broken, valve film 8 is pulled away from roundlet lid 6 under action of pressure, spring 7 is compressed simultaneously, ink flows to pressure adjustmenting mechanism 5 from ink storage chamber 1 via through holes 2, thereby pressure adjustmenting mechanism 5 to the pressure of 4 of ink outlet ports is risen.When pressure rose to a certain degree, pressure adjustmenting mechanism 5 was pushed valve film 8 to roundlet lid 6 again under its spring 7 elastic force effects own, and pressure adjustmenting mechanism 5 is in closed condition again.After pressure adjustmenting mechanism 5 was closed, in continuing the process of printing, 4 pressure reduced again from pressure adjustmenting mechanism 5 to ink outlet port, thereby makes pressure adjustmenting mechanism 5 return to open mode.In overall print process, this process is gone round and begun again, and makes to print to be continued to carry out.
In print procedure,, make in the ink outlet port 4 and remain certain negative pressure because of the effect of pressure adjustmenting mechanism 5.When print cartridge was taken out, because negative pressure, the inks in the ink outlet port 4 can reflux, thereby ink can't flow out ink outlet port 4, reached the purpose that prevents ink leak.
Print cartridge cover inboard is provided with air channel 9, and a part of space of air channel 9 is provided with a barrier material 10, and the barrier material 10 that this obstruct ink flows out is welded on the cover 13 through a film.When print cartridge was inverted, ink flow to passage 11 by air channel 9 needed a period of time, and in the period, barrier material 10 can stop the ink absorption that flows out the ink outflow simultaneously again, thereby also can reach the purpose that prevents ink leak at this section.
