Abstract
This utility model discloses an ink-jet printer cartridge, which comprises a cartridge body, a cover portion, an ink outlet, and an air guide hose, wherein the interior of the cartridge body forms an ink holding cavity, the cover portion for sealing the cartridge body is equipped with an air intake opening, the ink outlet is arranged at the bottom of the cartridge body and communicated with an ink cavity, one end of the air guide hose is communicated with atmosphere, and the other end of the air guide hose is inserted into the ink cavity through the air intake opening, floating on the ink liquid level. This utility model has the advantages of that the guide gas can prevent the ink from overflowing with good effect.
Description
Technical field
The utility model relates to a kind of ink-jet printer cartridge.
Background technology
At present, the employed print cartridge of ink-jet printer generally includes a box main body and cap, is formed with the inking chamber that holds ink in the inside of box main body, is provided with ink outlet port in the bottom.Cap is used for the seal box main body, and its surface is provided with the air admission hole that communicates with inking chamber.When printer is worked, utilize the suction function of printer ink-sucking port on the one hand, to be installed on the printer ink in the print cartridge from the ink outlet port sucking-off, realize inkjet printing, air then enters in the inking chamber from air admission hole on the other hand, be supplemented to ink and be sucked out formed space, back, reach pressure balance.The position of gas port need be designed to be installed on the printer in the normal use when print cartridge, and gas port can not have printing ink to flow out.
For preventing that printing ink from flowing out from gas port, normally the cover portion surface at print cartridge is provided with the snakelike air slot in the labyrinth that links to each other with gas port, and pastes the seal membrane of sealing snakelike air slot in labyrinth and gas port in cover portion surface.Usually, seal membrane is by along a tear line separated into two parts, and when tear line was torn seal membrane, the not end opening of the snakelike air slot in labyrinth was exposed in the atmosphere with box lunch.Thus, arround air can be through the labyrinth snakelike air slot and gas port enter print cartridge, but the still sealed diaphragm seal of the snakelike air slot of gas port and most of labyrinth spills to stop ink.But because of the infiltration and the capillarity of ink, this method can not thoroughly solve the ink leak problem of gas port, and the injection-molded structure complexity of the snakelike air slot in labyrinth, the processing cost height, and production efficiency is low.
For addressing the above problem, CN2695226Y discloses a kind of print cartridge, comprises box main body and cap.The inside of box main body forms the inking chamber that holds ink, and the bottom is provided with ink outlet port.The cap upper surface is provided with the black pit of storage, stores up black pit bottom and is provided with air admission hole, and the cap upper surface is provided with the groove that communicates with air admission hole.The lower end of air admission hole is a pipe that reaches the inking chamber bottom, and the head of pipe is equipped with check valve.When the inking chamber internal pressure reduces, one-way valve opens, gas enters inking chamber through air admission hole, pipe by check valve, and when pressure reached balance, closed check valve prevented that ink from flowing out through air admission hole from pipe.As a spot of ink from pipe when air admission hole flows out, can be stored in the black pit.Though this kind print cartridge is simple in structure, anti-ink leak effect is unsatisfactory, and check valve not only can't be regulated the interior ink pressure of inking chamber this moment, and can cause ink to flow out through air admission hole along pipe, the pollution surrounding environment with easy aging following the string after of a specified duration.Especially under environmental change and print cartridge inclination or inverted situation, ink leak is even more serious.
Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of ink-jet printer cartridge of air guide good leak-proof effect is provided.
For achieving the above object, the ink-jet printer cartridge that the utility model provides comprises: box main body, the inner inking chamber that holds ink that forms; The cap that has air admission hole is used for the seal box main body; Ink outlet port is located at the bottom of box main body, communicates with inking chamber; Soft air-guide pipe links to each other with air admission hole, and its free end is positioned at inking chamber, and floats on the ink level.
According to the ink-jet printer cartridge of above scheme, because of the free end of soft air-guide pipe swims on the ink level, be not immersed in the ink, can prevent effectively that ink from flowing out through air admission hole along soft air-guide pipe.
Scheme is that the free end of soft air-guide pipe is equipped with float preferably.
Another preferably scheme be that second end of soft air-guide pipe has a part spherical in shape.
Again one preferably scheme be the density of the density of soft air-guide pipe less than ink.
Float, part spherical in shape or lighter density can guarantee that all the free end of soft air-guide pipe floats on the surface, in the unlikely immersion ink.
Better scheme is the distance of the length of soft air-guide pipe greater than extremely relative with it the box main body one wall portion of cap, can guarantee by this under the situation of ink-jet printer cartridge inversion or inclination, the free end of soft air-guide pipe is still extended to ink level, in the unlikely immersion ink.
Description of drawings
Fig. 1 is the structural representation of the utility model ink-jet print cartridge;
Fig. 2 is that the utility model ink-jet printer cartridge is at the schematic diagram of dress attitude that tilts;
Fig. 3 is that the utility model ink-jet printer cartridge is at the schematic diagram of being inverted the dress attitude.
The specific embodiment
In conjunction with referring to Fig. 1, Fig. 2, Fig. 3, ink-jet printer cartridge A comprises a box main body 1 and cap 2.The inside of box main body 1 forms an inking chamber 11 that holds ink, and the bottom is provided with the ink outlet port 12 that communicates with inking chamber 11, is provided with the sealing device (not shown) in the ink outlet port 12 in case ink leakage.Cap 2 is installed in the top of box main body 1, is used for seal box main body 1, and is provided with an air admission hole 21.One soft air-guide pipe 3 is connected air inlet position, and extends in the inking chamber 11.The free end 31 of soft air-guide pipe 3 is positioned at inking chamber 11, and floats on the ink level, does not contact ink.Can guarantee that like this ink can not enter soft air-guide pipe 3 when inking chamber 11 inner air pressures increase, and flow out through air admission hole 21 along soft air-guide pipe 3.
Free end 31 at soft air-guide pipe 3 is equipped with float 32.The material of float 32 can be selected foam, PP plastics or other light material.Because the proportion of float 32 is more much smaller than ink, even therefore rock at ink-jet printer cartridge A, under inclination or the inverted situation, float 32 can guarantee that also the free end 31 of soft air-guide pipe 3 can float on the ink level all the time.
Soft air-guide pipe 3 is preferably made by resistant materials such as PE plastics, silica gel, has good pliability.Soft air-guide pipe 3 diameters are less usually, pass through to good just to allow gas.The length of soft air-guide pipe 3 preferably is a bit larger tham the distance of air admission hole 21 to box main body 11 bottoms, can guarantee ink-jet printer cartridge A like this under inclination or inverted situation, and the free end 31 of soft air-guide pipe 3 still can stretch out from ink level.
Be not limited in the foregoing description based on variation of the present utility model, also multiple variation can be arranged, as a spherical part being set by free end at soft air-guide pipe to replace float, or the employing soft air-guide pipe littler than ink density, they all can make the free end of soft air-guide pipe swim on the ink level, and the effect that obtains is identical.These simple structural changes still belong to the protection domain of the utility model requirement.
