Abstract
A negative pressure type print cartridge relates to the field of a print cartridge technology applied in an ink jet printer. To prevent the standby ink droplet phenomenon caused by a first ink warehouse negative pressure lack of the prior print cartridge, and to solve the disadvantage that ink break is easy to happen caused in that the ink of a second ink warehouse is not discharged fluently, the negative pressure type print cartridge includes a first ink warehouse and a second ink warehouse, and the bottom of the first ink warehouse is provided an ink outlet. The negative pressure type print cartridge is characterized in that the top of the second ink warehouse is provided with an air inlet, an inking channel is provided between the first ink warehouse and the second ink warehouse, the ink inlet terminal of the inking channel is arranged at the warehouse bottom of the second ink warehouse, and the ink outlet terminal is arranged at the warehouse top of the first ink warehouse. The lower the ink liquid level in the second ink warehouse is, the larger the negative pressure is, after the ink in the second ink warehouse is completely discharged, the ink in the first ink warehouse becomes to decrease, the stable supply of ink can be guaranteed, and the standby ink droplet problem is solved.
Description
Technical field
The utility model relates to the used print cartridge technical field of ink-jet printer.
Background technology
Shown in traditional print cartridge sees figures.1.and.2; Generally air admission hole 3a and ink outlet port 4a are located at top, storehouse and the bottom, storehouse of the first ink storehouse 1a (claiming the ink supply chamber again) respectively, the first ink storehouse 1a links to each other with dividing plate 5a bottom perforated 51a between the second ink storehouse 2a.Traditional this print cartridge pulls out bottom earlier when installation, tear yellow label; After printing beginning; Air gets into from the top, storehouse of the first ink storehouse 1a, prints the part ink of the first ink storehouse 1a earlier, makes sponge 6a that blotting is not full; Thereby begin to inhale the ink of its second ink storehouse 2a again; At this moment need the same ink exchange of air between the first ink storehouse 1a and the second ink storehouse 2a, air just gets into the dividing plate bottom perforated 51a that the second ink storehouse 2a links to each other from the first ink storehouse 1a, till having played the ink of the second ink storehouse 2a.Traditional this print cartridge is in print procedure, and the ink in the first ink storehouse 1a at first reduces, after the ink as the first ink storehouse 1a reduces; From air admission hole 3a, in the headroom of the first ink storehouse 1a, can replenish air in time; In the first ink storehouse 1a, can produce negative pressure hardly, in the standby process, just occur dripping black phenomenon easily; Thereby wasted ink pollutes printer; Moreover, the first ink storehouse 1a and the second ink storehouse 2a air with the ink exchange process in, it is untimely to occur exchange easily, thereby causes the ink outlet port black phenomenon of breaking, and influences print quality.When pulling out the bottom installation, sponge can go out from the ink outlet port ink leak when blotting is full.
Summary of the invention
In sum, the purpose of the utility model is that black phenomenon is dripped in standby, and the discharge of the second ink storehouse ink is not smooth for first ink storehouse that solves existing print cartridge lacks negative pressure, occurs the technological deficiency of disconnected China ink easily, and a kind of suction type print cartridge of proposition.
For solving the technical problem that the utility model proposed; The technical scheme that adopts is: a kind of suction type print cartridge, include first ink storehouse and second ink storehouse, and be provided with ink outlet port in the bottom of first ink storehouse; It is characterized in that: the top of described second ink storehouse is provided with air admission hole; Between first ink storehouse and second ink storehouse, be provided with inking channel, the China ink end that advances of said inking channel is located at bottom the storehouse of second ink storehouse, and ink-outtake end is located at the top, storehouse of first ink storehouse.
Include as the utility model being made further improved technical scheme:
Described print cartridge is built-in print cartridge.
When being built-in print cartridge, possibly be provided with cellucotton (also can not having cellucotton) in described first ink storehouse.
When being built-in print cartridge, possibly be provided with kapok core (also can not having the kapok core) in the described ink outlet port.
When being built-in print cartridge, the top, storehouse of described second ink storehouse also is provided with filler opening, in filler opening, is provided with the sealing plug.
Described print cartridge is external print cartridge.
When being external print cartridge, described first ink storehouse and second ink storehouse all respectively are provided with a filler opening, in filler opening, are provided with the sealing plug.
When being external print cartridge, described air admission hole is provided with and gets into the hole plug.
Described inking channel is that the groove and the PP film that are provided with on first ink storehouse and the second ink storehouse sidewall constitute.
The beneficial effect of the utility model is: the utility model is located at the top of second ink storehouse with air admission hole, because the first ink storehouse top except that the ink-outtake end of inking channel, is a structure that seals fully; Ink in first ink storehouse can't in time replenish air, under the effect of atmospheric pressure after discharging; Ink in second ink storehouse is transported to the first ink storehouse top from its bottom through inking channel, thereby adds in first ink storehouse, after the ink in second ink storehouse has been beaten fully; The air that gets into from air admission hole just can arrive the top of first ink storehouse through inking channel, and what at first reduce in the utility model print procedure is the ink in second ink storehouse, after the ink in second ink storehouse reduces; The ink level of second ink storehouse forms a difference in height with the ink entrance of first ink storehouse; In first ink storehouse, form negative pressure, the ink level of second ink storehouse is low more, and negative pressure is big more; After ink in second ink storehouse is discharged fully; The ink of first ink storehouse just begins to reduce, what guaranteed that ink can be stable confesses, and has solved the problem that China ink is dripped in standby.
