Abstract
The utility model relates to an ink box for ink-jet printer, which comprises an ink storage chamber to store ink, an ink outlet to provide ink for tattooing needles, an air hole with an air chamber to connect the ink storage chamber and external air and an one way valve to balance air pressure between the air hole and the ink storage chamber. In addition, the external end of the ink outlet is sealed with glue films or gasket rings. The one way valve is arranged into the air chamber between the ink storage chamber and air hole. Clearance fit is positioned between the one way valve and the air chamber, thus allowing ink to flow from the ink storage chamber to the air chamber. The utility model effectively alleviates pressure rise arising from temperature variation or insertion of the tattooing needle into the ink outlet and prevents ink leakage from the ink outlet.
Description
Technical field
The utility model relates to cartridge of ink-jet printer, particularly adopts the print cartridge of check valve as ink storage chamber air pressure balance control device.This print cartridge is assemblied on the print cartridge delivery balladeur train of ink-jet printer usually.
Background technology
The inkjet type record head is the necessary component parts of ink-jet printer.This record head is arranged on the balladeur train of ink-jet printer.The print cartridge of ink-jet printer is being undertaken the task to record head supply printing ink.
The storage ink chamber member that early stage print cartridge utilization can produce pressure provides pressure, for example in storage ink chamber sponge is set, and provides storage ink chamber required negative pressure state by its capillary channel.One of sidewall of storage ink chamber keeps fluid to be communicated with ink feed chambers, offers inkjet mouth on other sidewalls.Comprise the print cartridge of storing ink chamber, ink feed chambers and inkjet mouth, be removably installed on the balladeur train usually, and dock, in order to provide printing ink to record head with the record head coupling.Produce at inkjet mouth under the state of expulsion pressure, printing ink flows into the record head from this inkjet mouth, and then penetrates from the nozzle of record head, and splash is to paper.In response to the flowability that causes in the ink self gravitation, the surface tension that is arranged at the porous material generation in the storage ink chamber can stop storage ink chamber ink inside to be leaked by inkjet mouth because of fluid pressure.
In the print cartridge of recent development, adopt one-way valve mechanism to keep the interior negative pressure state of print cartridge ink storage chamber more.For example domestic patent documentation CN01116323.2 discloses a kind of " check valve body of Ink box device and outfit thereof ".Its valve body is arranged in the ink storage chamber of print cartridge, comprises supporting foot; Supporting walls portion, protuberance tilts from this inboard of supporting foot; One supports shoulder, constitutes from this supporting walls portion is crooked to the inside; With a supporting head part, support the shoulder protuberance from this, and be penetrated with a central through hole; One this central through hole of valve seal device shutoff.Thus, the valve body of this invention is kept black liquid, prevents that ink from leaking in ink storage chamber.
Keep the print cartridge of ink storage chamber negative pressure state for porous materials such as adopting check valve or sponge, all need be equipped with sealing mechanism usually at ink supply port.For example Chinese utility model patent specification CN03201870 provides a kind of sealing ring that integrates clearance seal function and pathway closure function.This sealing ring can reach good sealing effectiveness.Yet, because ink supply pin syringe needle inserts in the ink supply port, will cause being used to hold the dischargeable capacity minimizing of ink, this can cause in the ink supply port that the ink pressure that is inconjunction with in the ink storage chamber increases, and causes ink excessive along the ink supply port slit, pollutes paper.
The utility model content
The utility model purpose is to provide a kind of cartridge of ink-jet printer, and slowly-releasing increases because of ink supply port or the ink storage chamber ink pressure that causes in the ink supply pin syringe needle insertion ink supply port effectively.
According to the cartridge of ink-jet printer of above-mentioned purpose design, comprise the ink storage chamber that is used to store ink, be used for to the ink supply port of the ink supply pin supply ink of ink-jet printer, the check valve that is used to be communicated with the pore that has air cavity of ink storage chamber and outside atmosphere and is used to control air pressure balance between outside atmosphere and the ink storage chamber.Ink supply port seals its outside port by glued membrane or sealing ring.Check valve is installed in the position and is in the air cavity between ink storage chamber and the pore.Be characterized in being between check valve and the air cavity matched in clearance.This gap fiting mode allows ink to infiltrate air cavity in ink storage chamber.
Cartridge of ink-jet printer of the present utility model adopts on the print cartridge basis of check valve as ink storage chamber air pressure balance control device existing, adopts the gap fiting mode that allows the ink infiltrate between check valve and corresponding air cavity.Because the unidirectional opening feature of check valve in case converse pressure differential in the check valve opening direction occurs, then can not promptly digest this part pressure differential.This gap fiting mode then can be by converse ink bleed effect in the check valve opening direction, weaken effectively and thisly raise or the ink supply pin inserts the pressure differential that causes because of temperature, and then prevent ink along the print cartridge ink supply port to external leaks, keep clean printing environment.
The drawing explanation
Fig. 1 the utility model cartridge of ink-jet printer embodiment one cutaway view.
Fig. 2 is the partial enlarged view of Fig. 1.
Fig. 3 the utility model cartridge of ink-jet printer embodiment two local amplification views.
The specific embodiment
Referring to Fig. 1,2, cartridge of ink-jet printer embodiment one.This print cartridge comprises the ink storage chamber 1 that is used to store ink, is used for to the ink supply port 2 of the ink supply pin supply ink of ink-jet printer, the check valve 5 that is used to be communicated with the pore that has air cavity 34 of ink storage chamber 1 and outside atmosphere and is used to control air pressure balance between outside atmosphere and the ink storage chamber 1.Ink supply port 2 is then sealed up glued membrane by sealing ring 6 its outside ports of sealing simultaneously at the accumulating state.Check valve 5 is installed in the position and is in the air cavity 3 between ink storage chamber 1 and the pore 4.
Consult local amplification view shown in Figure 2.Check valve 5 is made of valve gap 501, Elastic valve core 502 and valve seat 503.Elastic valve core 502 is the slit shape otch 5021 offered of middle part radially, when ink storage chamber 1 pressure is lower than outside atmosphere, only allow gas from pore 4 through air cavity 3 by the unidirectional inflow ink storage chamber 1 of a of dotted arrow shown in the figure in; In the opposite situation of pressure state, slit shape otch 5021 is closed, and ink can not flow into air cavity 3 from ink storage chamber 1.Adopt gap fiting mode between check valve 5 outer surfaces and the air cavity 3.During greater than outside atmosphere, ink penetrates in the air cavity 3 by the b of dotted arrow shown in the figure through gap 504 at ink storage chamber 1 pressure.
Referring to Fig. 3, and by means of Fig. 1, cartridge of ink-jet printer embodiment two, its primary structure is identical with embodiment one, identical point is not done given unnecessary details.Dissimilarity is, contacting or the break-make of disengaged position control ink between the end wall of the through hole 6021 of Elastic valve core 602 by being arranged at self and the inner wall surface of valve gap 501.When ink storage chamber 1 pressure is lower than outside atmosphere, only allow gas from pore 4 through air cavity 3 by the unidirectional inflow ink storage chamber 1 of the c of dotted arrow shown in the figure in.During greater than outside atmosphere, ink penetrates in the air cavity 3 by the d of dotted arrow shown in the figure through gap 604 at ink storage chamber 1 pressure.
