The ink cartridge 100 includes: a housing 101 and an elastic oxygen barrier 102; the shell 100 is internally provided with a cavity 103 for containing ink 200, and the shell 100 is provided with an air port 104 and a liquid port 105 which are communicated with the cavity 103; the elastic oxygen-isolating piece 102 is positioned in the chamber 103 and divides the chamber 103 into an air pressure cavity 106 and a liquid storage cavity 107 which are mutually sealed and isolated; the air pressure chamber 106 is communicated with the air port 104, the liquid storage chamber 107 is communicated with the liquid port 105, and pressure change in the chambers is transmitted between the air pressure chamber 106 and the liquid storage chamber 107 through deformation of the elastic oxygen-isolating piece 102.
When the negative pressure in the air pressure cavity 106 is larger than the negative pressure in the liquid storage cavity 107 in the overall negative pressure state in the cavity 103, the elastic oxygen-isolating piece 102 deforms towards the air pressure cavity 106, so that the space of the air pressure cavity 106 is reduced, and the space of the liquid storage cavity 107 is enlarged; when the negative pressure in the air pressure chamber 106 is smaller than the negative pressure in the liquid storage chamber 107, the elastic oxygen barrier member 102 deforms in the direction of the liquid storage chamber 107, so that the space of the air pressure chamber 106 becomes larger and the space of the liquid storage chamber 107 becomes smaller.
When the positive pressure in the air pressure cavity 106 is greater than the positive pressure in the liquid storage cavity 107 in the state that the whole inside of the cavity 103 is in the positive pressure state, the elastic oxygen isolating piece 102 deforms towards the liquid storage cavity 107, so that the space of the air pressure cavity 106 is enlarged, and the space of the liquid storage cavity 107 is reduced; when the positive pressure in the air pressure chamber 106 is smaller than the positive pressure in the liquid storage chamber 107, the elastic oxygen barrier member 102 deforms in the direction of the air pressure chamber 106, so that the space of the air pressure chamber 106 becomes smaller and the space of the liquid storage chamber 107 becomes larger.
In another example, after the ink 200 flows out from the liquid port 107 of the ink cartridge 100, the liquid level in the liquid storage chamber 107 decreases, so that the air pressure in the liquid storage chamber 107 decreases, and the elastic oxygen barrier member 102 is deformed in the direction of the liquid storage chamber 107 in accordance with the liquid level of the ink 200.
The invention provides an ink box, which divides an original integrated cavity into an air pressure cavity and a liquid storage cavity which are mutually independent through an elastic oxygen isolation piece, effectively prevents control gas from contacting ink, and does not cause any influence on the ink in the liquid storage cavity even under the condition of shaking. On the other hand, the pressure change of the two chambers is transmitted by utilizing the self elastic deformation capacity of the elastic oxygen isolating piece, and the normal ink discharging of the ink is ensured. Therefore, the ink box can effectively reduce the formation of impurities in the ink box and ensure the normal ink discharge and good printing effect of the ink.
The air port, the liquid port, the opening and the like in the embodiment of the invention can be opened/closed by an electric control valve and/or a cap and the like, so that the requirements of various states of the ink box 100 during assembly, ink filling, transportation, printing work, disassembly and the like can be met. For example, during transportation, the "air port", "liquid port" and "opening" of the ink cartridge 100 may be closed to block the inside and outside of the ink cartridge.
As shown in fig. 2-3, in some embodiments, the elastic oxygen barrier 102 may be disposed in the chamber 103 at any angle, such that the chamber 103 forms a two-part cavity separated from the top and bottom, or a two-part cavity separated from the left and right, or the chamber 103 is separated at an angle from the horizontal or vertical direction. The elastic oxygen barrier member 102 may be an elastic oxygen barrier film or bladder, such as a film/bladder made of an elastic material with good air tightness.
In some embodiments, the air port 104 and the liquid port 105 may be disposed at any different positions on the housing 101, and due to the blocking of the elastic oxygen barrier 102, there is no influence between the air port 104 and the liquid port 105, and even if the liquid port 105 is disposed at the upper portion of the housing 101, the ink 200 in the liquid storage chamber 107 may be squeezed by the elastic oxygen barrier 102 to flow out from the liquid port 105 at the upper portion of the housing 101 by increasing the positive pressure in the air pressure chamber 106 and utilizing the deformation of the elastic oxygen barrier 102 toward the liquid storage chamber 107. Preferably, the liquid port 105 is provided at the bottom of the housing 101, which facilitates the outflow and stable control of the ink 200.
As shown in fig. 4-6, in some embodiments, the housing 101 may be formed by assembling at least two parts, such as the housing 101 assembled by the upper housing 101a and the lower housing 101b, or the housing 101 assembled by the left housing 101c and the right housing 101d, so as to facilitate the installation of the elastic oxygen barrier 102 in the housing 101. The housing 101 is assembled with care being taken to seal the splice location hermetically to prevent air leakage and liquid leakage.
In the first ink filling method (a) of the ink 200 in the ink cartridge 101, the housing 101 is assembled by joining the upper housing 101a and the lower housing 101b, and when filling ink, the liquid port 105 is first closed, the ink 200 is filled through the opening above the lower housing 101b, and then the upper housing 101a with the elastic oxygen barrier member 102 is assembled on the upper portion of the lower housing 101 b. The elastic oxygen barrier 102 may also be assembled on the upper portion of the lower casing 101b, so that the assembly of the elastic oxygen barrier 102 is completed before the upper casing 101a is assembled.
In the first ink filling mode (b) of the ink 200 in the ink cartridge 101, the housing 101 is assembled by splicing the upper housing 101a and the lower housing 101b, the liquid port 105 is arranged at the bottom of the lower housing 101b, ink filling from bottom to top is realized through the liquid port 105, and when the ink is filled to a specified liquid level, the upper housing 101a assembled with the elastic oxygen-barrier member 102 is assembled at the upper part of the lower housing 101 b. The elastic oxygen barrier 102 may also be assembled on the upper portion of the lower casing 101b, so that the assembly of the elastic oxygen barrier 102 is completed before the upper casing 101a is assembled.
The filling of the ink is completed from bottom to top, and for the ink (such as liquid metal) which is easy to react by air, excessive reactants do not appear in the ink, but only a thin layer of oxide film (such as gallium oxide) is formed on the highest liquid level of the ink, and due to the formation of the oxide film, more liquid is prevented from contacting with the air during the ink filling.
When the ink cartridge 101 is formed by joining left and right housings, the elastic oxygen barrier member 102 may be first assembled to form a closed chamber in the liquid storage chamber 107, and then the liquid port 105 may be directed upward to fill the ink, and exhaust gas may be discharged from the liquid port 105.
7-9, in some embodiments, housing 101 is provided with an opening 108 in communication with reservoir chamber 107; the opening 108 is used at least for discharging the gas in the liquid storage chamber 107 during ink filling. The embodiment can meet the requirement that the ink filling operation is performed after the splicing of the shell 101 is completed. Wherein the height of the opening 108 should be higher than the highest level of the ink 200 in the reservoir chamber 107. Preferably, the opening 108 is located at the uppermost portion of the reservoir chamber 107, while the port 105 is located at the bottom of the housing 101.
In the second ink filling method (a) of the ink 200 in the ink cartridge 101, when ink is filled into the assembled housing 101, the liquid port 105 is closed, ink can be filled from the top to the bottom through the opening 108, and the original gas in the liquid storage chamber 107 can be discharged through the opening 108, so that the gas can be sufficiently discharged.
In the second ink filling method (b) of the ink 200 in the ink cartridge 101, when ink is filled into the assembled case 101, ink is filled from the bottom to the top through the liquid port 105, and the gas in the liquid storage chamber 107 is discharged through the opening 108.
After the ink filling mode two (a) or the ink filling mode two (b) is completed, the opening 108 is closed.
In some embodiments, as shown in fig. 8-9, chamber 103 has an assembly structure within which an elastic oxygen barrier 102 is secured. Preferably, the mounting structure may include a snap groove 109 that forms an interference fit with the edge of the elastic oxygen barrier 102 and/or a baffle 110 that isolates a given location in the chamber 103.
Preferably, the baffle 110 has an extension 111 that limits the shape of the deformation of the elastic oxygen barrier 102; the extension 111 has at least one via 112 that allows the ink 200 to pass through.
In some embodiments, the junction between the sidewall and the bottom of the chamber 103 is of a rounded configuration to facilitate the approach of the resilient oxygen barrier 102.
In some embodiments, a print head 300 is provided at the location of the fluid port 105. The print head 300 may be a direct-write print head, an inkjet print head, or other ink discharge structure.
In some embodiments, the gas port is provided with a gas permeable membrane 113 covering the gas port, and external impurities enter the inside of the chamber 103.
In another aspect, a further object of the present invention is to provide a printing system to solve the technical problems in the prior art.
Referring to fig. 10-11, fig. 10 shows a schematic view of the structure of the printing system in an embodiment of the present invention (the elastic oxygen barrier is not deformed). Fig. 11 shows a schematic structural view of a printing system (elastic oxygen barrier deformation) in an embodiment of the present invention in some illustrative embodiments, the printing system comprises: the ink cartridge 100 of any of the above, and the air control system 400; the output end of the air control system 400 providing the control air pressure is communicated with the air port 104 of the ink cartridge 100.
As shown in fig. 12, in some embodiments, the pneumatic control system 400 includes: a gas line 401; a negative pressure member 402 communicating with the gas line 401 through a first solenoid valve 403; a positive pressure member 404 communicating with the gas line 401 through a second solenoid valve 405; a pressure relief member 406 communicating with the gas line 401 through a third electromagnetic valve 407; one end of the gas pipeline 401 is used as an output end of the pneumatic control system 400 for outputting control air pressure to the outside, and is connected to the air port 104 of the ink cartridge 100.
The negative pressure part 402 is used for outputting negative pressure, and a negative pressure air pump can be adopted; the positive pressure part 404 is used for outputting positive pressure, and a positive pressure air pump can be adopted; the pressure relief component is used for balancing the air pressure in the air pressure cavity 105 by utilizing the external air pressure, and a throttling silencing valve can be adopted.
In some embodiments, the pneumatic control system 400 may further include a pressure stabilizing cavity 408 communicated with the gas pipeline 401 to prevent air flow disturbance in the pneumatic control system 400 and the ink cartridge 100 communicated with the pneumatic control system 400, and to start the buffering function.
The printing system in the embodiment of the present invention initially uses a negative pressure and ink self-weight matching method to discharge ink, after the ink cartridge 100 is filled with ink and is communicated with the pneumatic control system 400, the negative pressure part 402 is opened (at this time, the positive pressure part 404 and the pressure relief part 406 are closed), so that the air pressure chamber 106 of the ink cartridge 100 is at a certain negative pressure, the ink 200 is discharged in a predetermined state, and the negative pressure part 402 is closed.
In the process of continuously discharging ink from the ink cartridge 100, the liquid level of the ink 200 in the liquid storage cavity 107 gradually decreases, the elastic oxygen barrier film 102 is driven to deform toward the liquid storage cavity 107 in accordance with the liquid level of the ink 200, the space of the air pressure cavity 106 is enlarged, the negative pressure is increased, and the negative pressure of the air pressure cavity 106 is reduced through the pressure relief component 406, so that the air pressure in the cavity 102 is maintained in a preset range, and the stable ink discharging of the ink is realized. In the process, the air pressure in the air pressure cavity 106 can be stably controlled through the matching of the negative pressure part 402 and the pressure relief part 406.
In some embodiments, during the gradual deformation of the elastic oxygen barrier member 102 along with the liquid level, due to the limitation of the elastic capability of the elastic oxygen barrier member 102 made of some materials, the negative pressure in the air pressure chamber 106 is reduced to be insufficient to support the continuous deformation of the elastic oxygen barrier member 102, and this defect can be compensated by activating the positive pressure component 404, so as to drive the elastic oxygen barrier member 102 to continuously deform and press towards the liquid storage chamber 107, thereby controlling the positive pressure to drive the stable ink discharge of the ink 200.
When the elastic oxygen-isolating piece 102 deforms, the elastic oxygen-isolating piece is firstly deformed from the center, then the periphery of the elastic oxygen-isolating piece is driven, when the deformation reaches a certain degree, the center of the elastic oxygen-isolating piece 102 firstly contacts the bottom surface of the cavity 102, the periphery of the cavity 102 can still form an ink channel, and until a certain moment, the elastic oxygen-isolating piece 102 completely approaches the bottom of the cavity 102, and all ink or all ink as far as possible is completely discharged.
The invention provides a printing system which not only has an ink box capable of effectively reducing the formation of impurities in the ink box and ensuring the normal ink discharge of ink and a good printing effect, but also prevents the problem that the ink box cannot finish the good ink discharge effect all the way by depending on the original negative pressure system due to the existence of an elastic oxygen isolating piece through a pneumatic control system with a positive pressure part.
