Description

Ink cartridge, ink cartridge control method, and ink cartridge pressurization method
Technical Field
The invention relates to the technical field of printing and imaging, in particular to an ink box, a control method of the ink box and a pressurizing method of the ink box.
Background
The ink cartridge is used to store printing ink and supply the ink to the ink jet printer to enable the ink jet printer to complete a printing job, and therefore, the ink cartridge is an integral part of the ink jet printer.
As shown in fig. 1, an ink cartridge 1 having a first case 11, a second case 12, a sealing film 13, and an ink bag 14 is provided in the related art. The ink bag 14 is in the first housing 11, and the sealing film 13 is used to close the first housing 11 into a closed space. The first housing 11 has a notch 110, and the notch 110 is used to hold the ink outlet 140. Establishing a coordinate system: the X-axis, Y-axis, and ink outlet 140 are arranged in the-Y-axis direction, generally the Y-axis is horizontal and the X-axis is vertical, so that the ink bag 14 is located in the-X-axis direction of the housing as shown in fig. 1. When the ink cartridge 1 is mounted to the printing apparatus, an ink supply needle in the printing apparatus enters the ink outlet 140. When the ink cartridge 1 supplies ink, pressurized air is applied to the pressurizing chamber 111 through a pressurizing port (not shown) of the ink cartridge 1 by a pressurizing device of the printing apparatus, and the pressurized air compresses the ink bag 14 to flow the ink in the ink storage portion 141 to the ink outlet 140, thereby supplying the printing apparatus with the required ink. Since the pressurizing chamber 111 is continuously pressurized by the pressurized air, the pressurizing chamber 111 applies pressure to the ink bag 14, and when the ink bag 14 contracts, a part of the ink bag 14 may be attached together, and the ink stored in a part (rear end side/+ Y axis side) of the ink bag 14 away from the ink outlet 140 may be blocked by the attached part of the ink bag 14, and the ink may remain in the ink bag 14 and cannot be consumed, thereby causing a technical problem of ink residue.
In order to solve the problem of causing ink residue in the prior art, the prior art provides another ink cartridge having a structure in which a pressurizing portion 15 is provided on the rear upper end side (+ X axis side, + Y axis side) of an ink bag 14 as shown in fig. 2. When the ink cartridge 1 supplies ink, the pressurizing portion 15 is filled with pressurized air to pressurize the ink bag 14, and the pressurizing portion 15 applies pressure to the + X and + Y axis sides of the ink bag 14 in addition to the pressure applied to the ink bag 14 by the pressurizing chamber 111. This ensures that ink on the rear end side (+ Y axis side) of the ink bag 14 preferentially moves in the direction of the ink outlet 140, and therefore ensures that ink on the + Y axis side of the ink bag 14 is preferentially consumed. However, both of the pressurizing chambers 111 of the prior art shown in fig. 1 and 2 apply a force to the whole ink bag 14, the pressurizing chamber 111 is generally formed by directly sealing the case body and the case cover or by welding the film 13 (shown in fig. 1 and 2) on the case body, the structure of the pressurizing chamber 111 has a great influence on the pressurizing effect, and the pressurizing chamber 111 in this case has: difficult to ensure the sealing performance, high welding requirement, large processing difficulty, easy breakage of the welding part of the sealing film and the like.

The valve 28 may be a self-sealing valve, in this embodiment, the valve 28 may be a regulating valve for controlling the pressure between the first pressurizing part 24 and the second pressurizing part 25, the regulating valve is provided with a slit, and the regulating valve is thin plate, thin cylinder or semispherical, generally, the valve 28 is made of soft rubber, such as silica gel, and the slit is in a sealing state when the ink cartridge 2 is not pressurized. Assume that the pressure P1 of the first pressurization portion 24, the pressure P2 of the second pressurization portion 25, the pressure threshold PA at which the valve 28 opens; when | P1-P2| < PA, the slit of the valve 28 is closed, the valve 28 is in a closed state, and the first pressurizing portion 24 and the second pressurizing portion 25 are not communicated with each other, as shown in fig. 4, and the pressurizing pump performs the pressurizing operation only on the first pressurizing portion 24; when the first pressurizing part 24 is continuously pressurized, the pressure of | P1-P2| ≧ PA appears, at this time, the pressurizing part with smaller pressure (namely, the second pressurizing part 25) forms larger suction force to the valve 28, the valve 28 deforms, when the deformation reaches a certain degree, the notch is opened, at this time, the valve 28 is opened, the first pressurizing part 24 is communicated with the second pressurizing part 25, as shown in fig. 5, at this time, the pressurizing pump pressurizes the first pressurizing part 24 and the second pressurizing part 25; therefore, the first pressurizing part 24 and the second pressurizing part 25 are selectively communicated, and as is clear from the above statement, the first pressurizing part 24 and the second pressurizing part 25 can be selectively communicated according to the pressure difference of the pressurizing fluid; it should be noted that, in the present embodiment, the second pressurization part 25 is connected to the first pressurization part 24 through the valve 28 and the second fluid pipe 27, and those skilled in the art may also adopt other connection manners, for example, the second pressurization part 25 may be directly connected to the first pressurization part 24 through the valve 28.
It should be noted that, as will be understood by those skilled in the art, the total number of the first pressurizing part 24 and the second pressurizing part 25 is not limited to 2, and may be 3 or more than 3, as long as the features of the first pressurizing part 24 and the second pressurizing part 25 of the present embodiment are met, the effects of the present embodiment can be achieved.
In the ink cartridge 2 provided in this embodiment, the ink cartridge 2 further includes the second pressurization portion 25, the first pressurization portion 24 and the second pressurization portion 25 are selectively communicated, and the second pressurization portion 25 is closer to the ink outlet 22 than the first pressurization portion 24, so that the first pressurization portion 24 is pressurized first, and the second pressurization portion 25 is pressurized later, so that the ink can be stirred during the ink supplying process, and the uniformity of the ink concentration is ensured, and the problems in the prior art are overcome, and because the first pressurization portion 24 is located at the rear end side (+ Y axis side) of the second pressurization portion 25, the ink at the rear end side (+ Y axis side) of the ink bag 21 is first pressurized to the ink outlet 22, and then the ink close to the ink outlet 22 is pressurized, so that the ink residue in the ink bag 21 is reduced, and the ink residue at the rear end side (+ Y axis side) of the ink bag 21 is avoided, thereby effectively improving the practicability of the ink cartridge 2, is beneficial to the popularization and the application of the market.
On the basis of the above embodiment, with continued reference to fig. 1 to 5, in a specific application, in order to further reduce the ink residue in the ink bag 21, in this embodiment, the expansion volume of the first pressurization part 24 may be set to be larger than the expansion volume of the second pressurization part 25, where the first pressurization part 24 with the larger expansion volume may apply a larger first pressure to the ink bag 21, the second pressurization part 25 with the smaller expansion volume may apply a smaller second pressure to the ink bag 21, and the second pressure is smaller than the first pressure, so as to ensure that the ink residue in the ink bag 21 is further reduced, and at the same time, it is beneficial to implement: the first pressurizing portion 24 and the second pressurizing portion 25 are selectively communicated with each other according to a pressure difference of the pressurizing fluid.
For the implementation in which the expanded volume of the first pressurization part 24 is larger than the expanded volume of the second pressurization part 25, several ways can be used: 1. the first pressurization part 24 and the second pressurization part 25 are made of the same material, but the volume of the first pressurization part 24 is larger than that of the second pressurization part 25, so that the expanded first pressurization part 24 and the expanded second pressurization part 25 can be ensured to be different; 2. the first pressurizing part 24 and the second pressurizing part 25 are made of materials with different elastic modulus, and generally, the elastic modulus of the first pressurizing part 24 is smaller than that of the second pressurizing part 25; 3. the first pressurizing part 24 and the second pressurizing part 25 are made of materials with different elastic moduli, and the volume of the first pressurizing part 24 is different from that of the second pressurizing part 25; of course, those skilled in the art may also adopt other implementation manners according to specific design requirements, as long as the expanded volume of the first pressurization part 24 is larger than that of the second pressurization part 25, which is not described herein again.
The first and second pressing portions 24 and 25 (hereinafter, collectively referred to as pressing portions) may be made of an elastic material, and the material may be rubber, aluminum film, latex, plastic, oxford, PVC, aluminum foil, PA, PE, or the like. When the pressure-increasing part is filled with the pressurized fluid, the pressure-increasing part expands under the pressure of the pressurized fluid, and when the pressurized fluid is not in the pressure-increasing part, the pressure-increasing part can contract; when pressurized fluid is present within the pressurization section, the pressurization section may again expand.
Further, another form of the first pressurizing portion 24 and the second pressurizing portion 25 (collectively referred to as pressurizing portions) may be as shown in fig. 6b and 6 a. FIG. 6a is a front view of the first pressurization part 24/the second pressurization part 25 according to the first embodiment of the present invention; fig. 6b is a side view of the first pressurization part 24/the second pressurization part 25 according to the first embodiment of the present invention. The pressurizing portion is formed by a molding film welded to the wall of the cartridge case. The pressurization part is provided with: the ink box comprises a non-deformation part 251 used for being connected to the ink box wall, a transition part 252 connected with the non-deformation part 251, and a deformation part 253 connected with the transition part 252, wherein the transition part 252 is arranged between the deformation part 253 and the non-deformation part 251, and the transition part 252 is arranged outside the deformation part 253 in a surrounding mode.
As shown in fig. 6a and 6b, the pressurizing portion may be formed by a molded film welded to the wall of the casing of the ink cartridge 2. The molding film of the pressing part comprises a deformation part 253, a transition part 252 and a non-deformation part 251. Generally, the deformations 253 and the transitions 252 may expand under the force of a pressurized fluid and contract in the absence of the pressurized fluid. The non-deforming part 251 is used to weld the molding film to the wall of the casing of the ink cartridge 2 to form a pressing part. The formed film can be made of a composite stretched film (CNY30/DLCPP50) imported from Japan as a material of the film. As will be appreciated by those skilled in the art, the original properties of the film include: the deformability is minimal, the elasticity is minimal, and there is no ability to expand and contract under pressure. However, after the film is processed by a high temperature device such as a hot press or a hot welding head (not shown), the film can be deformed differently from the previous deformation of the deformation portion 253 and the transition portion 252, and the film can expand and contract under the pressure, which achieves the technical effect of the embodiment.
In the present embodiment, the expansion volume of the first pressurization part 24 is set to be larger than the expansion volume of the second pressurization part 25, so that the pressure of the second pressurization part 25 on the ink bag 21 can be effectively ensured to be smaller than the pressure of the first pressurization part 24 on the ink bag 21, the ink on the rear end side of the ink bag 21 can be further ensured to be more smoothly supplied to the ink outlet 22, and the stability and reliability of the use of the ink cartridge 2 are improved.
Further, in order to apply uniform pressure to the ink bag 21, the ink cartridge 2 is configured to further include a partition 29, the first pressurizing unit 24 and/or the second pressurizing unit 25 are/is disposed on one side of the partition 29, and the ink bag 21 is disposed on the other side of the partition 29.
Note that, since the first pressurization part 24 and the second pressurization part 25 may be provided on the upper end side of the ink bag 21, or the first pressurization part 24 and the second pressurization part 25 may also be provided on the lower end side of the ink bag 21, or the first pressurization part 24 and the second pressurization part 25 may be provided on the upper end side and the lower end side of the ink bag 21, respectively; therefore, the partition 29 in this case also has three different arrangement structures, for example, as shown in fig. 7-8a and 8b, when the first and second pressurizing portions 24 and 25 can be arranged on the upper end side of the ink bag 21 and the ink cartridge 2 further includes the partition 29 described above, in this case, the partition 29 is positioned on the upper end side of the ink bag 21 and on the lower end side of the first and second pressurizing portions 24 and 25; as shown in fig. 9, when the first and second pressurizing portions 24 and 25 may be provided on the lower end side of the ink bag 21 and the ink cartridge 2 further includes the partition 29, the partition 29 is positioned on the lower end side of the ink bag 21 and on the upper end side of the first and second pressurizing portions 24 and 25. The ink sedimentation is on the lower end side (the (-X axis side) in the vertical direction, so that the first pressurizing part 24 and the second pressurizing part 25 are arranged on the lower end side of the ink bag 21, and the ink stirring effect is more obvious; another arrangement structure of the partition 29 is: the first pressurization part 24 or the second pressurization part 25 and the ink bag 21 are disposed on one side of the partition 29, and the second pressurization part 25 or the first pressurization part 24 is disposed on the other side of the partition 29, and the specific configuration form is similar to the two configuration structures, which can be referred to the above statements specifically, and will not be repeated herein.
In a specific application, as shown in fig. 8a, when the first pressing portion 24 presses, the partition 29 tilts, and the first pressing portion 24 more uniformly applies pressure to the partition 29 to press the ink on the rear end side of the ink bag 21 to the ink outlet 22; as shown in fig. 8b, when the valve 28 between the first pressurizing part 24 and the second pressurizing part 25 is opened, the second pressurizing part 25 can be pressurized, and the inclination of the partition 29 can be relieved, so that the ink can be sufficiently stirred, and the ink concentration can be more uniform.
By arranging the ink cartridge 2 to further include the partition 29, the partition 29 can separate the first pressurization part 24 and the second pressurization part 25 from the ink bag 21, so that the pressure exerted by the first pressurization part 24 and the second pressurization part 25 on the ink bag 21 can be ensured to be more uniform, and the ink on the rear end side of the ink bag 21 can be preferentially pressed to the ink outlet 22 during the ink supply process, thereby further ensuring the use effect of the ink cartridge 2.
Further, the present embodiment may also be arranged such that the ink cartridge 2 further includes a pressing plate 210 for applying pressure to the ink bag 21, and the ink bag 21 is disposed between the pressing plate 210 and the partition 29.
Note that, since the partition 29 may be located on the upper end side of the ink bag 21 and on the lower end side of the first and second pressing portions 24 and 25; alternatively, the partition 29 may be positioned on the lower end side of the ink bag 21 and on the upper end side of the first and second pressurizing portions 24 and 25; therefore, in the case of the pressing plate 210, the pressing plate 210 also has two different arrangement structures, for example, when the first and second pressing portions 24 and 25 can be arranged on the upper end side of the ink bag 21, the partition 29 is located on the upper end side of the ink bag 21 and on the lower end side of the first and second pressing portions 24 and 25, in the case of the pressing plate 210, the pressing plate 210 is located on the lower end side of the ink bag 21; alternatively, as shown in fig. 10, when the first pressurizing portion 24 and the second pressurizing portion 25 may be provided on the lower end side of the ink bag 21 and the partition 29 is positioned on the lower end side of the ink bag 21 and on the upper end side of the first pressurizing portion 24 and the second pressurizing portion 25, in this case, the pressing plate 210 is positioned on the upper end side of the ink bag 21 with respect to the pressing plate 210, and it is preferable that the pressing plate 210 is provided on the upper end side of the ink bag 21 in consideration of the fact that the pressing plate 210 itself can exert a partial pressure action on the ink bag 21.
By arranging the ink cartridge 2 to further comprise the pressing plate 210, further, the pressing plate 210 can be arranged on the upper end side of the ink bag 21, so that the ink bag 21 is always subjected to the force given by the pressing plate 210 in the ink supply process, the smoothness of ink supply of the ink bag 21 is more obvious, and the stability and the reliability of the use of the ink cartridge 2 are further improved.
Further, the present embodiment may further provide that the ink cartridge 2 further includes an atmosphere communication port 211 for communicating with the atmosphere insertion pin, the atmosphere communication port 211 is connected to the second pressurization portion 25, and the atmosphere communication port 211 is mainly used for performing a pressure relief operation on the second pressurization portion 25.
It should be noted that, since the first pressurization part 24 and the second pressurization part 25 may be disposed on the upper end side of the ink bag 21, or the first pressurization part 24 and the second pressurization part 25 may also be disposed on the lower end side of the ink bag 21, since the atmosphere communication port 211 is connected to the second pressurization part 25, in order to facilitate the disposition of the atmosphere communication port 211, in general, when the second pressurization part 25 is disposed on the upper end side of the ink bag 21, the atmosphere communication port 211 may be disposed on the upper end side of the ink outlet 22, and the ink outlet 22 is connected to the ink bag 21, and the specific structure is shown in fig. 11; similarly, when the second pressurizing portion 25 is provided on the lower end side of the ink bag 21, the atmosphere communication port 211 may be provided on the lower end side of the ink outlet 22.
No matter whether the atmosphere communicating port 211 is disposed at the upper end side or the lower end side of the ink outlet 22, in a specific application, the atmosphere inserting needle and the inserting needle (i.e., the outlet portion) for being connected with the atmosphere communicating port 211 may be connected to a same double-pipe for controlling the communication/closing of the atmosphere inserting needle and the inserting needle (i.e., the outlet portion).
In particular, in an achievable manner, a two-way tube can be used for: when the contact pin (namely the outlet part) and the communication port 23 are pressurized, the atmosphere contact pin and atmosphere communication port 211 is controlled to be closed; when the atmosphere pin is communicated with the atmosphere communication port 211, the control pin (i.e. the outlet portion) and the communication port 23 are closed.
When the printing device or the ink box receives a printing ending command, the first pressurizing part 24 and the second pressurizing part 25 need to be subjected to pressure relief operation, so that the atmosphere communication port 211 can be controlled to be communicated with the atmosphere, the pin inserting passage is closed, and the second pressurizing part 25 is communicated with the atmosphere communication port 211, so that the pressure of the second pressurizing part 25 can be reduced to be consistent with the atmospheric pressure; when the pressure P1 of the first pressurization part 24-the pressure P2 of the second pressurization part 25 ≧ the pressure threshold PA at which the valve 28 opens, due to the action of the valve 28, the valve 28 opens, and the pressure of the first pressurization part 24 may also decrease, but when the pressurization part finishes the depressurization, the first pressurization part 24 may still retain a certain pressure. When the printing apparatus prints again, the atmospheric communication port 211 is closed, the needle-connected pressurizing pump pressurizes the first pressurizing portion 24, the pressurization of the first pressurizing portion 24 is increased, and when the pressure P1 of the first pressurizing portion 24 — the pressure P2 of the second pressurizing portion 25 is greater than or equal to the pressure threshold PA at which the valve 28 is opened, the valve 28 is opened (the slit of the valve 28 is opened in this embodiment), and the first pressurizing portion 24 communicates with the second pressurizing portion 25.
In another way, a two-way tube can be used: when the contact pin (namely the outlet part) and the communication port 23 are pressurized, the atmosphere contact pin and atmosphere communication port 211 is controlled to be closed; when the contact pin (i.e. outlet portion) is communicated with atmosphere, the atmosphere contact pin is controlled to be communicated with the atmosphere communication port 211.
During the application, when receiving the printing end command, need carry out the pressure release operation to first pressurization portion 24 and second pressurization portion 25 this moment, and then can control atmosphere intercommunication mouth 211 and atmosphere intercommunication, the contact pin passageway switches on atmosphere, to first pressurization portion 24 and second pressurization portion 25 pressure release, first pressurization portion 24 and second pressurization portion 25 pressure all reduce atmospheric pressure, consequently can avoid ink horn 2 or first pressurization portion 24, second pressurization portion 25 to be in high-pressure state effectively.
The ink horn 2 that this embodiment provided, atmosphere intercommunication mouth 211 through setting up, and be used for the atmosphere contact pin that is connected with this atmosphere intercommunication mouth 211 and contact pin can be connected same double-pass pipe, can avoid appearing being difficult to guarantee the leakproofness effectively, the welding requirement is high, the processing degree of difficulty is big, the welding department of sealing film breaks easily and waits defect, and realized still effectively being in the pressure release state to 2 insides of ink horn when not printing, consequently, ink horn 2 can not be in the pressurization state for a long time, the long-term high pressure state of first pressurization portion 24/second pressurization portion 25 can not appear yet, thereby the condition that the elastic force that first pressurization portion 24/second pressurization portion 25 caused because of the material is tired weakens has been avoided appearing, the stable and reliable nature that ink horn 2 used has further been guaranteed.
Fig. 12 is a schematic flow chart illustrating a method of controlling an ink cartridge according to a first embodiment of the present invention, and fig. 13 is a schematic flow chart illustrating selective communication between a first pressurizing portion and a second pressurizing portion according to a pressure difference of a pressurizing fluid according to a first embodiment of the present invention; referring to fig. 12 to 13, the present embodiment provides a method for controlling an ink cartridge 2 according to any one of the above embodiments, and the specific structure of the ink cartridge is shown in fig. 3 to 11, and the method includes:
s101: when the ink cartridge is not pressurized in the initial state, the first pressurizing part 24 and the second pressurizing part 25 in the ink cartridge 2 are not communicated;
when the ink cartridge 2 is mounted to the printing apparatus, the first and second pressing portions 24 and 25 are not pressed in the initial state, and the first and second pressing portions 24 and 25 are not connected at this time, as shown in fig. 3.
S102: pressurizing the first pressurizing section 24;
when the printing apparatus receives a printing command or connects the power supply, the pressurizing pump starts to pressurize, the pressurized air reaches the first pressurizing portion 24 through the communication port 23 and the first fluid tube 26, at this time, in the initial stage of pressurization, only the first pressurizing portion 24 is pressurized, and at this time, the first pressurizing portion 24 and the second pressurizing portion 25 are not communicated, as shown in fig. 4, at this time, the pressurized first pressurizing portion 24 expands to pressurize the ink bag 21, because the first pressurizing portion 24 is disposed at the rear end side of the ink bag 21, the ink at the rear end side of the ink bag 21 can be preferentially pressurized toward the ink outlet 22.
S103: the first pressurizing portion 24 and the second pressurizing portion 25 are selectively communicated with each other according to a pressure difference of the pressurizing fluid.
Further, the selective communication between the first pressurizing portion 24 and the second pressurizing portion 25 according to the pressure difference of the pressurizing fluid may be provided to include:
s1031: when the pressure difference between the first pressurizing part 24 and the second pressurizing part 25 reaches a preset pressure threshold, the first pressurizing part 24 and the second pressurizing part 25 are communicated;
after the first pressurization part 24 is in communication with the second pressurization part 25, the method further comprises:
pressurizing the first pressurizing part 24 and the second pressurizing part 25 to realize that the pressurized first pressurizing part 24 and the pressurized second pressurizing part 25 apply pressure to the ink bag 21 in the ink box 2; the pressure applied by the first pressurizing unit 24 to the ink bag 21 is greater than the pressure applied by the second pressurizing unit 25 to the ink bag 21.
S1032: when the pressure difference between the first pressurizing portion 24 and the second pressurizing portion 25 is smaller than the preset pressure threshold, the first pressurizing portion 24 and the second pressurizing portion 25 are not communicated with each other.
As the pressurizing pump continues to pressurize, the pressure of the first pressurizing portion 24 continues to rise, and when the pressure P1 of the first pressurizing portion 24 — the pressure P2 of the second pressurizing portion 25 is greater than or equal to the pressure threshold PA at which the valve 28 opens, the valve 28 opens (in this embodiment, the slit of the valve 28 opens), and the first pressurizing portion 24 communicates with the second pressurizing portion 25, as shown in fig. 5, at which time the second pressurizing portion 25 starts to be filled with pressurized fluid; when the pressure P1 of the first pressurization part 24 to the pressure P2 of the second pressurization part 25 < the pressure threshold PA at which the valve 28 is opened, the valve 28 is closed, and the first pressurization part 24 and the second pressurization part 25 are not communicated.
Further, as shown in fig. 4, when only the first pressurizing portion 24 is pressurized, the first pressurizing portion 24 applies pressure to the ink bag 21, and the ink in the ink bag 21 flows to a position where no pressure is applied by the pressure, so that the ink in the ink bag 21 can be stirred. As shown in fig. 5, when the second pressurization part 25 is pressurized, both pressurization parts will apply pressure to the ink bag 21, and the first pressurization part 24 is on the rear end side (+ Y axis side) of the second pressurization part 25, so the ink stirring function of the ink bag 21 will be more obvious, and therefore, the scheme can stir the ink in the ink supplying process, and the condition that the ink is layered or the ink concentration is uneven due to ink precipitation will not occur.
In the control method of the ink cartridge 2 provided in this embodiment, in the pressurization process, the first pressurization part 24 is pressurized first, the second pressurization part 25 is pressurized later, and the first pressurization part 24 is located on the rear end side (+ Y axis side) of the second pressurization part 25, so that the ink on the rear end side (+ Y axis side) of the ink bag 21 is first pressed to the ink outlet 22, and then the ink on the front end side (-Y axis side) of the ink bag 21 or the ink close to the ink outlet 22 is squeezed, so that the ink residue in the ink bag 21 can be reduced, the elastic ink is prevented from remaining on the rear end side of the ink bag 21, and further the waste of the ink and the residual ink amount are prevented; and this embodiment adopts first pressurization portion 24 and second pressurization portion 25 to pressurize around the ink bag 21, has abandoned the pressurized mode when prior art adopts the pressurization, has avoided appearing being difficult to guarantee that leakproofness, welding require high, the processing degree of difficulty is big, the technical problem that the welded junction of sealing film breaks easily etc. in addition, can also stir the ink at the black in-process of supplying ink, has guaranteed that ink concentration is even, is favorable to the output that the ink is more smooth.
Further, in a specific application, the present embodiment may further set the control method of the ink cartridge 2 to include:
when the ink box 2 receives a command of stopping printing or finishing printing, the communication port 23 on the ink box 2 is controlled to be communicated with the atmosphere through a contact pin (namely an outlet part), and the first pressurization part 24 is depressurized.
Specifically, after the first pressurization part 24 is depressurized, the method may further include:
when the pressure difference between the first pressurizing part 24 and the second pressurizing part 25 reaches the preset pressure threshold, the first pressurizing part 24 and the second pressurizing part 25 are communicated, and the first pressurizing part 24 and the second pressurizing part 25 are simultaneously depressurized.
During application, when the printing equipment stops printing or receives a printing end command, the communication port 23 and the contact pin are communicated with the atmosphere through the control of the pressurizing pump, and the first pressurizing part 24 is used for decompressing; specifically, the communication port 23 communicates with the first pressurizing portion 24, and therefore, the pressure of the first pressurizing portion 24 can be reduced to coincide with the atmospheric pressure; due to the action of the valve 28, when the pressure P2 of the second pressurization part 25 — the pressure P1 of the first pressurization part 24 is greater than or equal to the pressure threshold PA at which the valve 28 opens, the valve 28 opens (in this embodiment, the notch of the valve 28 opens), the pressure of the second pressurization part 25 can also decrease, but when the pressure relief of the second pressurization part 25 and the first pressurization part 24 is finished, a certain pressure still remains in the second pressurization part 25, for example: the pressure of the second pressurizing portion 25 in this embodiment is PA (if the atmospheric pressure is 0). It will be appreciated by those skilled in the art that in general, the pressure P1> PA of the first pressurization portion 24 will be as long as the valve 28 is open during pressurization. When the printer prints again, the first pressure portion 24 is pressurized by the pressure pump, and the pressurization of the first pressure portion 24 is raised, and the ink on the rear end side of the ink bag 21 can be similarly pressed toward the ink outlet 22. The pressurizing pump continues to pressurize, the pressure of the first pressurizing part 24 continues to rise, and when the pressure P1 of the first pressurizing part 24-the pressure P2 of the second pressurizing part 25 ≧ the pressure threshold PA at which the valve 28 opens, the valve 28 opens (in this embodiment, the slit of the valve 28 opens), and the first pressurizing part 24 communicates with the second pressurizing part 25.
Still further, another method for venting the first pressurization part 24 and the second pressurization part 25 includes:
when the ink box 2 receives a command of stopping printing or finishing printing, the atmosphere communication port 211 on the ink box 2 is controlled to be communicated with the atmosphere, the contact pin (namely the outlet part) and the communication port 23 are controlled to be closed, and the second pressurization part 25 is depressurized.
Specifically, after the second pressurization part 25 is depressurized, the method is configured to further include:
when the pressure difference between the first pressurizing part 24 and the second pressurizing part 25 reaches the preset pressure threshold, the first pressurizing part 24 and the second pressurizing part 25 are communicated, and the first pressurizing part 24 and the second pressurizing part 25 are simultaneously depressurized.
When the pressure relief device is applied, when a printing end command is received, the atmosphere communication port 211 is communicated with the atmosphere, the pin inserting passage is closed, and the second pressurization part 25 is subjected to pressure relief, specifically, the second pressurization part 25 is communicated with the atmosphere communication port 211, so that the pressure of the second pressurization part 25 can be reduced to be consistent with the atmospheric pressure; when the pressure P1 of the first pressurization part 24-the pressure P2 of the second pressurization part 25 is greater than or equal to the pressure threshold PA at which the valve 28 is opened due to the action of the valve 28, the valve 28 is opened, and the pressure of the first pressurization part 24 can also be reduced, but when the pressure relief of the first pressurization part 24 and the second pressurization part 25 is finished, a certain pressure can still be maintained in the first pressurization part 24.
