Description

Technical Field

[0001] The invention relates to the technical field of printing consumables, in particular to an ink cartridge and an inkjet printer. Background Art

[0002] The European patent document with the publication number EP2010392B1 discloses an ink cartridge, which includes a deformable cavity located in an ink storage cavity, the deformable cavity is formed by a flexible film, and a gas charging port connected to a pump of a printer is provided on the side wall of the ink cartridge, and the gas charging port is communicated with the deformable cavity. When printing starts, the pump pressurizes the deformable cavity through the gas charging port under the action of a controller, and the deformable cavity expands, causing the ink in the ink storage cavity to be squeezed out from the ink supply port, and the ink flows into the print head, thereby discharging the air accumulated in the print head to remove the bubbles in the print head.

[0003] However, since the deformable cavity is accommodated in the middle of the ink storage cavity, when the deformable cavity is pressurized, the ink in the ink storage cavity diffuses to the surroundings, and only a small amount of ink is discharged through the ink supply port, so the pump is required to pressurize the deformable cavity multiple times.

[0004] The patent document with the announcement number CN203157372U discloses an ink cartridge, which includes a one-way valve, which includes a valve chamber arranged on a housing, a spring located in the valve chamber, a deformable elastic component, a valve cover and other parts. There are too many parts, and it is difficult to ensure the sealing during assembly. In addition, due to the presence of the partition, the ink cartridge will have the following problems during use: when the airbag expands, the liquid is compressed instantly. Since the one-way valve is closed, and the partition prevents the flow of liquid between two adjacent ink storage chambers, the pressure of the liquid will act on the housing, causing cracks to appear at the welding point between the cover and the housing, thereby causing the ink cartridge to rupture and leak ink. At the same time, the liquid will squeeze the airbag, causing the airbag to be ruptured due to excessive force instantly. Therefore, the ink cartridge structure has high requirements for welding technology, high processing difficulty, and the welding point is easy to rupture, resulting in high processing costs and other problems. Summary of the invention

[0005] The main object of the present invention is to provide an ink cartridge which has a simple structure and can improve the efficiency of removing bubbles in a print head.

[0006] Another object of the present invention is to provide an inkjet printer equipped with the above-mentioned ink cartridge.

[0007] To achieve the above main purpose, the present invention provides an ink cartridge, including a shell, an ink holding chamber, a deformable chamber, an ink outlet, an air filling port and an air guide port, the ink holding chamber and the deformable chamber are both arranged in the shell, the ink outlet, the air filling port and the air guide port are all arranged on the side wall of the shell, the ink outlet is connected to the ink holding chamber, and the air filling port is connected to the deformable chamber. The ink cartridge also includes a connecting chamber, a buffer channel and a slow resistance chamber that are connected to each other, the ink holding chamber and the slow resistance chamber are respectively arranged on both sides of the connecting chamber, the ink holding chamber and the connecting chamber are separated by a partition wall, and a connecting port is opened at the bottom of the partition wall. The connecting chamber is connected to the slow resistance chamber through the buffer channel, the buffer channel has a first ink inlet end and a first ink outlet end, the buffer channel extends from the first ink inlet end to the first ink outlet end from bottom to top, the first ink inlet end is connected to the connecting chamber, and the first ink outlet end is connected to the slow resistance chamber. The number of the slow resistance chambers is more than two, and at least two slow resistance chambers are filled with porous materials. The slow resistance chamber is connected to the air guide port, and the air guide port is connected to the external atmosphere.

[0008] It can be seen from the above scheme that before printing starts, the pump of the printer inflates the deformable cavity from the inflation port, the deformable cavity expands, the pressure in the ink holding cavity increases, part of the ink flows from the ink outlet to the print head, and part of the ink enters the connecting cavity from the connecting port. When the ink in the connecting cavity is full, the ink enters the buffer cavity from the buffer channel, and the porous material in the buffer cavity absorbs the ink to avoid ink leakage. After the ink flows to the print head, the pump stops working, the deformable cavity shrinks, and the gas in the deformable cavity is discharged through the inflation port. A certain negative pressure is maintained in the ink holding cavity, thereby attracting bubbles in the print head to the ink cartridge to remove the bubbles in the print head.

[0009] Since the ink entering the connecting cavity from the connecting port needs to overcome gravity to do work, the setting of the slow resistance cavity and the porous material increases the flow resistance of the ink in the slow resistance cavity, so only a small part of the ink enters the connecting cavity from the connecting port, and most of the ink flows from the ink outlet to the print head, thereby improving the bubble removal efficiency in the print head, so the pump does not need to pressurize the deformable cavity multiple times. In addition, since the connecting port is opened on the partition wall, when the pressure in the ink holding cavity increases, a part of the ink can enter the connecting cavity from the connecting port to reduce the pressure inside the shell, so there will be no problem in the prior art that the pressure of the liquid acts on the shell, causing cracks to appear at the welding point between the cover and the shell, resulting in the rupture of the ink cartridge and the air bag and ink leakage.

[0010] During printing, the pump does not work, and the ink in the ink holding chamber is continuously consumed, causing the negative pressure in the ink holding chamber to gradually increase. At this time, external gas enters the shell from the air guide port, and the air pressure in the ink holding chamber is balanced with the external air pressure, and the ink in the buffer chamber, the buffer channel and the connecting chamber flows back into the ink holding chamber.

[0011] A preferred solution is that the buffer chamber includes a first buffer chamber and a second buffer chamber, and the first buffer chamber is located above the second buffer chamber. The first buffer chamber and the second buffer chamber are both filled with porous materials. The ink inlet of the first buffer chamber is connected to the first ink outlet end of the buffer channel, and the ink outlet of the first buffer chamber is connected to the second buffer chamber through an air guide groove, and the air guide groove is formed on the outer surface of the shell. The air guide port is connected to the second buffer chamber.

[0012] It can be seen that processing the air guide groove on a plane with a larger area can simplify the production process, and can also make the air guide groove longer, thereby enhancing the reliability of leak prevention. The porous materials such as sponge filled in the first and second slow resistance cavities form an absorption cavity to absorb part of the ink that penetrates into the first and second slow resistance cavities, thereby further improving the leak prevention.

[0013] A further solution is that the air guide groove has at least one U-shaped bend.

[0014] It can be seen that the length of the air guide groove is increased, and the U-shaped bend can further improve the leak-proof performance.

[0015] A further solution is that the number of the first slow resistance chambers is more than two, and the multiple first slow resistance chambers are interconnected.

[0016] It can be seen that the plurality of first slow resistance chambers are connected in sequence, which can effectively delay the time for ink to enter the second slow resistance chamber and improve the leakage resistance.

[0017] A further solution is that the two first buffer chambers are connected through a buffer groove, and the buffer groove has a second ink inlet end and a second ink outlet end, and the buffer groove extends from the second ink inlet end to the second ink outlet end from bottom to top.

[0018] It can be seen that the buffer groove extends from bottom to top, which can increase the flow resistance of the ink, thereby reducing the amount of ink flowing into the second buffer chamber.

[0019] A further solution is that the buffer grooves are arranged in a stepped manner.

[0020] It can be seen that this solution increases the length of the buffer groove, thereby extending the flow channel of the ink and reducing the amount of ink flowing into the second buffer cavity.

[0021] A preferred solution is that, along the flow direction of the ink, the porous material is filled in the plurality of first resistance chambers at intervals.

[0022] A preferred solution is that the housing includes a top wall, a bottom wall, a front wall and a rear wall, the air inlet and the ink outlet are both arranged on the front wall. The partition wall includes a vertical extension portion and an inclined extension portion, the vertical extension portion extends vertically downward from the top wall, the first end of the inclined extension portion is connected to the vertical extension portion, the second end of the inclined extension portion is connected to the bottom wall, and the second end of the inclined extension portion is closer to the rear wall than the first end of the inclined extension portion.

[0023] It can be seen that the provision of the inclined extension portion can, on the one hand, increase the volume of the ink containing cavity, and on the other hand, facilitate the ink to enter the communicating cavity from the communicating port.

[0024] A preferred solution is that the ink cartridge further includes a piston and a reset member. The housing includes a right wall, and an annular protrusion is further provided in the housing from the right wall into the housing, the annular protrusion is located in the ink receiving chamber, the piston can move along the extension direction of the annular protrusion, and the right wall, the annular protrusion and the piston form a deformable chamber. The restoring force of the reset member forces the piston to move toward the right wall.

[0025] It can be seen that when the pump inflates the deformable cavity, the piston overcomes the force of the reset member and moves away from the right wall of the housing, and the deformable cavity expands. When the pump no longer inflates the deformable cavity, the piston moves under the restoring force of the reset member, the volume of the deformable cavity decreases, and the deformable cavity is in a contracted state. During the printing process, the deformable cavity also maintains a contracted state.

[0026] To achieve the other purpose mentioned above, the present invention provides an inkjet printer, including a main body, on which an ink cartridge installation position is provided, and the ink cartridge is detachably installed on the ink cartridge installation position. The inkjet printer also includes a pump that can be connected to the ink cartridge and inflate and pressurize the ink cartridge, and the pump inflates the deformable cavity through the inflation port.

[0035] See also Figure 1 and Figure 2 The ink cartridge includes a housing 1, an ink containing chamber 2, a deformable chamber 3, an ink outlet 131, an air filling port 132, and an air guide port 151 ( Figure 3 ), an elastic membrane (not shown), a reset member 31, a connecting cavity 4, a buffer channel 5 and a buffer resistance cavity 6.

[0036] The shell 1 includes a top wall 11, a bottom wall 12, a front wall 13, a rear wall 14 and a right wall 15. The ink outlet 131 is located at the lower part of the front wall 13.

[0037] The ink containing chamber 2 and the slow resistance chamber 6 are respectively arranged on both sides of the communication chamber 4, and the ink containing chamber 2 and the communication chamber 4 are separated by a partition wall 41, and a communication port 42 is provided at the bottom of the partition wall 41. The partition wall 41 includes a vertical extension portion 43 and an inclined extension portion 44, the vertical extension portion 43 extends vertically downward from the top wall 11, a first end of the inclined extension portion 44 is connected to the vertical extension portion 43, a second end of the inclined extension portion 44 is connected to the bottom wall 12, and the second end of the inclined extension portion 44 is closer to the rear wall 14 than the first end of the inclined extension portion 44.

[0038] The connecting chamber 4 and the slow resistance chamber 6 are separated by a partition wall 45, and a connecting port 451 is provided at the bottom of the partition wall 45. The connecting chamber 4 and the slow resistance chamber 6 are connected through a buffer channel 5, and the buffer channel 5 has an ink inlet end 51 and an ink outlet end 52. The buffer channel 5 extends from the ink inlet end 51 to the ink outlet end 52 from bottom to top, and the ink inlet end 51 is connected to the connecting chamber 4 through the connecting port 451, and the ink outlet end 52 is connected to the slow resistance chamber 6. The slow resistance chamber 6 is connected to the air guide port 151, and the air guide port 151 is connected to the external atmosphere.

[0039] See also Figures 2 to 4 The slow resistance chamber 6 includes a first slow resistance chamber 61 and a second slow resistance chamber 62, and the first slow resistance chamber 61 is located above the second slow resistance chamber 62. The number of the first slow resistance chamber 61 is five, namely, a slow resistance chamber 611, a slow resistance chamber 612, a slow resistance chamber 613, a slow resistance chamber 614 and a slow resistance chamber 615 which are connected in sequence.

[0040] The ink inlet hole 6111 of the buffer chamber 611 is connected to the first ink outlet end 52 of the buffer channel 5, and the buffer chamber 611 is connected to the buffer chamber 612 through the buffer groove 616. The buffer groove 616 has an ink inlet end 6161 and an ink outlet end 6162. The buffer groove 616 extends from the ink inlet end 6161 to the ink outlet end 6162 from bottom to top in a stepped shape. The ink inlet end 6161 is connected to the ink outlet 6112 of the buffer chamber 611, and the ink outlet end 6162 is connected to the ink inlet 6121 of the buffer chamber 612 through the buffer groove 617. The resistance chamber 612 is connected to the resistance chamber 613 through the connecting port 6122, the resistance chamber 613 is connected to the resistance chamber 614 through the buffer groove 618, the ink outlet 6131 of the resistance chamber 613 is connected to the ink inlet end 6181 of the buffer groove 618, and the ink inlet 6141 of the resistance chamber 614 is connected to the ink outlet end 6182 of the buffer groove 618. The resistance chamber 614 is connected to the resistance chamber 615 through the connecting port 6142. The ink inlet and the ink outlet of each resistance chamber are arranged at the diagonal of the resistance chamber as much as possible, so as to maximize the distance between the ink inlet and the ink outlet, so as to extend the path of ink flow in each resistance chamber.

[0041] The ink outlet hole 6151 of the buffer chamber 615 is connected to the second buffer chamber 62 through the air guide groove 63. The buffer groove 617, the buffer groove 618 and the air guide groove 63 are all formed on the outer surface of the right wall 15 of the shell 1. The air guide port 151 is located on the side wall of the second buffer chamber 62, and the side wall is also provided with an air inlet 152, and the air inlet 152 is connected to the air guide groove 63. The air guide groove has at least one U-shaped bend. In this embodiment, the number of U-shaped bends is five, and the heads and tails of the five U-shaped bends are connected in sequence.

[0042] The second slow resistance chamber 62 is connected to the external atmosphere through the air guide port 151. When the ink cartridge is not installed in the inkjet printer, the sealing film 60 seals the air guide port 151, and the sealing film is torn off before the ink cartridge is installed in the inkjet printer.

[0043] Processing the air guide groove 63 and the buffer grooves 617 and 618 on a plane with a larger area can simplify the production process and can also make the air guide groove 63, the buffer groove 617 and the buffer groove 618 longer, thereby enhancing the anti-leakage reliability.

[0044] At least one of the five first slow resistance chambers 61 is filled with a porous material 60 such as a sponge, and the second slow resistance chamber 62 is also filled with a porous material 60 such as a sponge. In this embodiment, the slow resistance chamber 612 and the slow resistance chamber 614 are filled with sponges, and the slow resistance chamber 611, the slow resistance chamber 613 and the slow resistance chamber 615 are not filled with sponges, that is, along the flow direction of the ink, the porous material 60 is filled in the multiple first slow resistance chambers 61 at intervals. The slow resistance chamber filled with sponges forms an absorption chamber, which absorbs part of the ink that penetrates therein, further improving the leak-proof performance.

[0045] The housing 1 is also provided with an annular protrusion 16 protruding from the right wall 15 into the ink containing chamber 2, the elastic membrane is provided at one end of the annular protrusion 16, the right wall 15 of the housing 1, the annular protrusion 16 and the elastic membrane form a deformable chamber 3, the reset member 31 is located in the deformable chamber 3, the two ends of the reset member 31 are respectively connected to the housing 1 and the elastic membrane, and the restoring force of the reset member 31 forces the elastic membrane to move toward the right wall 15 of the housing 1. Preferably, the reset member 31 is a spring.

[0046] Before printing begins, the pump of the printer inflates the deformable chamber 3 from the inflation port 132, the deformable chamber 3 expands, the pressure in the ink holding chamber 2 increases, part of the ink flows from the ink outlet 131 to the print head, and part of the ink enters the connecting chamber 4 from the connecting port 42. When the ink in the connecting chamber 4 is full, the ink enters the buffer chamber 6 from the buffer channel 5, and the porous material 60 in the buffer chamber 6 absorbs the ink to prevent ink leakage. After the ink flows to the print head, the pump stops working, the deformable chamber 3 shrinks, and the gas in the deformable chamber 3 is discharged through the inflation port 132. A certain negative pressure is maintained in the ink holding chamber 2, thereby attracting the bubbles in the print head to the ink cartridge to remove the bubbles in the print head.

[0047] Since the ink entering the communication cavity 4 from the communication port 42 needs to overcome gravity to do work, the setting of the slow resistance cavity 6 and the porous material 60 increases the flow resistance of the ink in the slow resistance cavity 6, so only a small part of the ink enters the communication cavity 4 from the communication port 42, and most of the ink flows to the print head from the ink outlet 131, thereby improving the bubble removal efficiency in the print head, so the pump does not need to pressurize the deformable cavity 3 multiple times. In addition, since the communication port 42 is provided on the partition wall 41, when the pressure in the ink holding cavity 2 increases, a part of the ink can enter the communication cavity 4 from the communication port 42 to reduce the pressure inside the shell 1. Therefore, the problem of the pressure of the liquid acting on the shell 1 in the prior art, causing cracks to appear at the welding point between the cover and the shell 1, and causing the ink cartridge and the air bag to rupture and leak ink, will not occur.

[0048] During printing, the pump does not work, and the ink in the ink holding chamber 2 is continuously consumed, causing the negative pressure in the ink holding chamber 2 to gradually increase. At this time, external gas enters the shell 1 from the air guide port 151, and the air pressure in the ink holding chamber 2 is balanced with the external air pressure, and the ink in the buffer chamber 6, the buffer channel 5 and the connecting chamber 4 flows back into the ink holding chamber 2.

[0049] In addition, the number of first buffer chambers can be one or more than two, and multiple first buffer chambers are interconnected. The partition wall can also only include a vertical extension portion, and the two ends of the vertical extension portion are respectively connected to the top wall and the bottom wall. The number of U-shaped bends of the air guide groove can be changed as needed. Each first buffer chamber can also be filled with porous materials such as sponge. The above changes can also achieve the purpose of the present invention.

[0050] Ink cartridge and inkjet printer second embodiment

[0051] As an explanation of the second embodiment of the ink cartridge and the inkjet printer of the present invention, only the differences from the first embodiment of the ink cartridge and the inkjet printer described above will be explained below.

[0052] See also Figure 5 The deformable cavity 230 of this embodiment is surrounded by the right wall 231 of the housing, the annular protrusion 232 and the piston 233. The piston 233 cooperates with the inner peripheral wall of the annular protrusion 232 and can move along the extension direction of the annular protrusion 232. The restoring force of the reset member 234 forces the piston 233 to move toward the right wall 231 of the housing. The piston 233 is made of elastic material such as rubber.

[0053] The ink cartridge further includes a limiting member 235 , which is fixedly mounted on one end of the annular protrusion 232 opposite to the right wall 231 of the housing. Both ends of the reset member 234 abut against the piston 233 and the limiting member 235 , respectively.

[0054] In addition, the deformable cavity can also be a flexible bag made of flexible material. The annular protrusion can also extend to the left wall of the shell and be adjacent to the left wall or fixedly connected by bonding or welding. The above changes can also achieve the purpose of the present invention.

[0055] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
