The utility model discloses an anti-overflow air inlet device for ink boxes, which is an air inlet device for ink boxes and has simple structure and good anti-overflow effect. The utility model is arranged on an ink box cover which covers an ink box body. At least one chamber is arranged in an interlayer which is arranged in the ink box cover. The top of the chamber and the upper surface of the ink box cover are communicated with the external side of the ink box through an upper air inlet hole, and the bottom of the chamber or the sides of the chamber are communicated with the lower surface of the ink box cover through a lower air inlet hole. Through holes arranged among chambers are communicated with each other. The interlayer is formed by sticking films on the surface of the ink box cover. Multihole elastomers are placed in the chambers. The device has strong versatility and the ink box cover with the device can replace all kinds of ink box covers with air inlet holes.
Description
Technical field
The utility model relates to a kind of print cartridge of ink-jet printer, more specifically to a kind of anti-overflow inlet duct of print cartridge.
Background technology
At present, the employed print cartridge of ink-jet printer is that the ink box cover seam by cartridge body that is shaped on ink outlet port and sealing cartridge body forms, and adds ink injection in the cavity between cartridge body and ink box cover, also be shaped on the print cartridge with print cartridge in the air admission hole that is interlinked to the outside.When printer is worked, utilize the suction function of printer ink-sucking port, will be installed on the printer ink in the print cartridge from the ink outlet port sucking-off, realize inkjet printing, air enters in the cartridge body from air admission hole, replenishes the ink of sucking-off, reaches pressure balance.Because print cartridge is to rock back and forth in printing, overflows from air admission hole in order to prevent ink always, the air admission hole of many print cartridges is made labyrinth shape, to stop the excessive of ink.But this method mould is made complicated, and the anti-overflow effect is unsatisfactory.
The utility model content
The utility model has overcome deficiency of the prior art, and a kind of simple in structure, inlet duct that anti-overflow is effective is provided.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: print cartridge anti-overflow inlet duct is on the ink box cover that covers cartridge body, in ink box cover, be shaped on interlayer, has a chamber in the interlayer at least, the top of chamber and the upper surface of ink box cover are interlinked to the outside by last air admission hole and print cartridge, the bottom of chamber or side communicate with the lower surface of ink box cover by following air admission hole, are shaped on through hole between each chamber, are interconnected.In chamber, be placed with porous elastomers.
Print cartridge anti-overflow inlet duct according to the such scheme manufacturing has the following advantages:
1, simple in structure, be easy to make.
2, highly versatile has the ink box cover of this device, can substitute the various ink box covers that air admission hole is arranged.

Among the figure: 1, ink box cover; 2 fences; 3, dividing plate; 4, film 5,6, chamber; 7, go up air admission hole; 8, following air admission hole; 9, through hole; 10, mandruka; 11, groove; 12, ink outlet port; 13, cartridge body; 14, marking ink.
The specific embodiment
The utility model will be further described below by embodiment.
Fig. 1, Fig. 2, Fig. 3 are that a kind of two chambers are all at the structural representation of the anti-overflow inlet duct of print cartridge upper surface.Print cartridge anti-overflow inlet duct is on the ink box cover 1 that covers cartridge body, the low fence 2 that exceeds ink box cover 1 lower surface all around in the middle of the lower surface of ink box cover 1 is shaped on, in the middle of fence 2, be divided into two Room with dividing plate 3, bonding with film 4 on 2 mouthfuls of fences, make ink box cover form interlayer and two chambers, i.e. chamber 5, chamber 6.The upper surface of the top of chamber 5 and ink box cover 1 is interlinked to the outside with ink box cover 1 by last air admission hole 7; The bottom sides of chamber 6 communicates with the lower surface of ink box cover 1 by following air admission hole 8, be shaped on through hole 9 on the dividing plate 3 between chamber 5,6 bottoms, make chamber 5,6 be interconnected, wherein descending air admission hole 8, through hole 9 is relevant position gaps 2 mouthfuls of fences, forms with film 4 bonding backs on 2 mouthfuls of fences again.By last air admission hole 7, through hole 9, following air admission hole 8, the upper surface of ink box cover 1 and lower surface are connected, form airway.The size and dimension of ink box cover 1 is determined with the opening that covers cartridge body.After ink box cover 1 that has print cartridge anti-overflow inlet duct and cartridge body seam, the air turnover in the print cartridge just comes equalizing pressure by this airway.In addition, because the existence of chamber 5,6 makes the ink that overflows from following air admission hole 8 that a transition be arranged, and is stored in the chamber 5,6, ink is difficult for excessive outside to ink box cover 1.
Fig. 4 is another embodiment, is on the basis of Fig. 1, Fig. 2, Fig. 3 embodiment, is filled with mandruka 10 in the chamber 6, can more effectively stop overflowing of ink.
Fig. 5 is another kind of embodiment, is on the basis of Fig. 4 embodiment, also is filled with mandruka 10 in the chamber 5, can stop overflowing of ink more significantly.
Fig. 6 is another embodiment, just on the basis of Fig. 5 embodiment chamber 5,6 is merged into a chamber, plays the effect of anti-overflow equally.
Fig. 7, Fig. 8, a kind of two chambers of Fig. 9 are all at the structural representation of the anti-overflow inlet duct of print cartridge upper surface.Be shaped on the boss of ink box cover 1 upper surface protruding upward on ink box cover 1, form plenum chamber in boss, be divided into two Room with dividing plate 3 in the middle of plenum chamber, the top of a chamber is interlinked to the outside with ink box cover 1 by last air admission hole 7 therein; On having dividing plate 3 between 11, two chambers of groove, the lower surface of another chamber port and ink box cover 1 is shaped on breach, and bonding with film 4 on chamber port, and make groove 11 not exclusively bonding, form interlayer and two chambers, through hole 9, air admission hole 8 down.By last air admission hole 7, through hole 9, following air admission hole 8, the upper surface of ink box cover 1 and lower surface are connected, form airway.
Figure 10 is another embodiment, is on the basis of Fig. 7, Fig. 8, Fig. 9 embodiment, is filled with mandruka 10 in the chamber, can stop overflowing of ink effectively.
Figure 11 is the structural representation that has after ink box cover 1 and cartridge body 13 seam that have ink outlet port 12 of print cartridge anti-overflow inlet duct of two chambers.Be placed with mandruka 10 in the chamber therein, in the cavity that ink box cover 1 and cartridge body 13 are formed, be perfused with marking ink 14.
Certainly, similarly combining structure also has many kinds, and the chamber in the interlayer can have a plurality of as one, two, three etc.; Chamber can be arranged on the upper surface or the lower surface of ink box cover 1; Various ways such as placing porous sponge 10 whether in the chamber.
