Description
Technical field
It the utility model is related to a kind of print cartridge, and in particular to a kind of print cartridge of internal pressure balance.
Background technology
Present print cartridge, is typically provided the ink supply chamber and ink storage chamber separated by dividing plate in it, ink supply chamber upper end be provided with into
Stomata, lower end are provided with ink outlet port, and the lower end of ink storage chamber connects ink supply chamber, this knot by being arranged at the ink port of dividing plate lower end
It is empty because ink storage chamber upper end is unable to air inlet, therefore only when ink supply chamber ink inside is less than the ink port on dividing plate in structure design
Gas could smoothly enter ink storage chamber, and the ink in ink storage chamber could smoothly enter ink supply chamber.But due to the ink in ink storage chamber
With certain gravity, ink that can be by ink port to be transferred in ink supply chamber, the pressure of ink outlet port is increased.This print cartridge it is another
Structure design is that air admission hole is located to the upper end of ink storage chamber, and in printing, the ink in ink supply chamber is drawn and forms negative pressure, stores up
Ink in black chamber enters ink supply chamber by the atmospheric pressure and the suction function of air inlet position from ink port, is formed and followed with this
Ring, because the size of ink port is smaller, increment of the ink into ink supply chamber in ink storage chamber is less than the amount out of ink of ink outlet port, most
The amount of drawing of printer is caused to reduce eventually, print quality is low.
Secondly, need to set sponge to adsorb ink in the ink supply chamber of print cartridge, to avoid drop ink.But traditional print cartridge, supply
Black chamber lower end, which is closed up, sets a cross section less than the cylinder cavity of ink supply chamber cross section to form ink outlet port, if using monoblock type
Sponge, it is meant that need to cut out the convex closure with the ink outlet port size, shape matching, the life of this mode of production in one end of sponge
It is very high to produce cost, and stock utilization is low, fraction defective is high, and therefore, traditional print cartridge is arranged to two pieces of sponges, one piece is filled in
In ink supply chamber, one piece is filled in ink outlet port, and its production cost is still quite high, and needs to install sponge twice when assembling, and produces
Efficiency is low.
Utility model content
In order to solve the above problems, the utility model, which provides one kind, is both turned on ink supply chamber and ink storage chamber upper and lower end, but in
Between spaced-apart and solve the ink in ink storage chamber to ink outlet port press, realize internal pressure balance print cartridge.
Technical scheme is used by the utility model solves its technical problem：A kind of print cartridge of internal pressure balance, including ink
Box main body, the upper end of the toner cartridge main body are provided with air admission hole, and lower end is provided with ink outlet port, is provided with the toner cartridge main body：
Ink supply chamber, the lower end connection ink outlet port of the ink supply chamber；
Ink storage chamber, the top and bottom of the ink storage chamber are respectively communicated with the top and bottom of ink supply chamber, and the ink supply chamber
Upper end or ink storage chamber upper end connection air admission hole.
Preferably, the side wall of the toner cartridge main body is provided with sluice way, and one end of the sluice way is connected under ink storage chamber
End, other end connection ink supply chamber.
Preferably, the sluice way is provided with one or more.
Preferably, the sluice way is taken shape on the lateral wall of toner cartridge main body, and its one end connects the lower end of ink storage chamber, another
The lower end of end connection ink supply chamber.
Preferably, the cross section of the ink supply chamber horizontal direction is constant, and the lower end of ink supply chamber is opening, the side of the openend
Wall is inwardly horizontal-extending to be set a circle boss and forms ink outlet port, and ink supply intracavitary is provided with the sponge of matching, the lower end patch of sponge
Close boss upper end.
Preferably, in addition at least one secondary ink storage chamber, the lower end of the secondary ink storage chamber connect ink storage chamber.
Preferably, being separated between the ink supply chamber and ink storage chamber by dividing plate, the upper end of the dividing plate sets air-flow through hole,
To realize connecting for ink supply chamber and ink storage chamber upper end.
The beneficial effects of the utility model are：Ink supply chamber and ink storage chamber upper and lower end are both turned on, but center section separates,
During printing, ink supply chamber can keep concordant with the upper surface of the ink in ink storage chamber, in the lower end connectivity part of ink supply chamber and ink storage chamber,
The gravity at both ends is identical, solves the problems, such as that ink storage chamber ink inside of the prior art is pressurized to ink outlet port, realizes internal pressure
Dynamic balance, while in printing, the upper surface of ink storage chamber and ink supply chamber ink inside is acted on by atmospheric pressure simultaneously, the ink of ink outlet port
Water discharge capacity is sufficient, and print quality is good；Secondly, by the way that ink supply chamber to be arranged to the cylinder cavity structure of a lower ending opening, under it
Boss is extended at end opening, can directly use a sponge being adapted to ink supply chamber, it is no longer necessary to individually process one
The sponge of ink outlet port position is installed on, greatly reduces production cost, while also improves production efficiency, it is simple in construction, it is real
It is strong with property.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structural representation of the utility model first embodiment；
Fig. 2 is the structural representation of the utility model second embodiment.
Embodiment
Reference picture 1, the utility model are a kind of print cartridges of internal pressure balance, including toner cartridge main body, the toner cartridge main body it is upper
End is provided with air admission hole, and lower end is provided with ink outlet port 6, it is characterised in that is provided with the toner cartridge main body：
Ink supply chamber 1, the lower end connection ink outlet port 6 of the ink supply chamber 1；
Ink storage chamber 2, the top and bottom of the ink storage chamber 2 are respectively communicated with the top and bottom of ink supply chamber 1, and the ink supply
The upper end of chamber 1 or the upper end connection air admission hole of ink storage chamber 2.
Specifically, being provided with a dividing plate 8 between ink supply chamber 1 and ink storage chamber 2, the upper end of dividing plate 8 is provided with passage 4, makes ink supply chamber 1
