Description

Technical Field

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

[0002] An inkjet printer converts colored liquid ink into fine particles through a nozzle and sprays it onto printing paper. Ink cartridges are an indispensable component of an inkjet printer. At present, common ink cartridges for inkjet printers are generally divided into two types: one is an ink cartridge that can be manually added with ink, and the other is an ink cartridge that cannot be added with ink. When adding ink to the ink cartridge that can be added with ink, a syringe is used to add ink into the ink cartridge. However, adding ink with a syringe not only injects air into the ink cartridge, but also fails to achieve continuous ink supply. Each time, the ink is filled up at one time and then added after the ink is used up. This is very cumbersome to use. Moreover, when adding ink, the ink is easy to overflow and contaminate the contacts, resulting in contact damage. Therefore, the present invention provides an ink cartridge structure for an inkjet printer to solve the above-mentioned problems. Summary of the invention

[0003] The object of the present invention is to provide an ink cartridge structure for an inkjet printer to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A cartridge structure for an inkjet printer comprises a shell, a top cover is clamped on the upper end of the shell, a storage bin is clamped inside the shell, the interior of the storage bin is filled with a sponge for slowly releasing ink, a continuous ink supply structure is movably connected to the right end of the storage bin, the continuous ink supply structure comprises an ink storage cartridge, two docking sleeves for conveying ink are symmetrically fixedly connected to one end of the ink storage cartridge close to the storage cartridge, and two docking ports are symmetrically fixedly connected to one end of the storage cartridge close to the ink storage cartridge, and the docking ports are inserted in the docking sleeves, and a second anti-reverse sleeve for preventing ink leakage is also fixedly connected to the docking sleeve.

[0008] As a further solution of the present invention, the front and rear ends of the ink storage cartridge are fixedly connected with a pressure tube and a pressure supply tube for ensuring the stable movement of the ink supply piston, the inside of the pressure tube is slidably connected with the pressure piston, the end of the pressure piston close to the storage bin is fixedly connected with a piston rod, the piston rod is fixedly connected to the outer wall of the storage bin, the pressure tube and the ink storage cartridge are connected by a first one-way tube, the pressure tube and the pressure supply tube are connected by a second one-way tube, and the pressure supply tube and the ink storage cartridge are connected by a third one-way tube.

[0009] As a further solution of the present invention, a pressure supply piston is slidably connected inside the pressure supply pipe, and a continuous pushing structure for decelerating the pressure supply piston is installed inside the pressure supply pipe.

[0010] As a further solution of the present invention, the continuous pushing structure includes a protective sleeve fixedly connected to the inside of the pressure supply pipe, the inside of the protective sleeve is fixedly connected to a rifle sleeve, the inside of the rifle sleeve is connected to a rifle rod, the protective sleeve is also fixedly connected to an electromagnet and a force storage spring, the internal thread of the rifle rod is connected to a threaded rod, and the end of the threaded rod close to the pressure supply piston is rotatably connected to the pressure supply piston.

[0011] As a further solution of the present invention, the end of the pressure supply piston close to the rifle rod is fixedly connected to a fixed gear ring, the interior of the fixed gear ring is rotatably connected to a positioning gear ring, the side of the positioning gear ring close to the rifle rod is fixedly connected to a speed reduction cover, and the speed reduction cover and the fixed gear ring are connected by a one-way bearing, a clockwork spring is installed inside the speed reduction cover, one end of the clockwork spring is fixedly connected to the speed reduction cover, and the other end is fixedly connected to the rifle rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When the present invention is used, after the ink storage cartridge enters, the pressure supply piston no longer drives the rifle rod to move. At this time, the clockwork spring begins to release energy. At this time, the rotation of the positioning gear ring will drive the positioning frame to rotate through a number of transition gears, and the positioning frame drives the threaded rod to rotate. The rotation speed of the threaded rod is less than the rotation speed of the positioning gear ring. Therefore, at this time, the threaded rod will slowly move toward the outside of the rifle rod under the action of the thread, and then push the pressure supply piston to move, so that the air in the pressure supply pipe enters the ink storage cartridge to push the ink supply piston to move, and as the ink supply piston moves, the ink can be slowly pushed into the storage bin. In this way, it can be avoided that the internal structure of the sponge is damaged due to too fast ink addition, and it can be avoided that the ink is sprayed from the nozzle and polluted. When the storage bin is full of ink, the ink in the ink storage cartridge cannot enter. At this time, the capacity of the clockwork spring cannot be released, so the ink supply can be stopped. When the ink in the storage bin is reduced, the ink supply can be resumed, thereby completing continuous ink addition.

[0016] 2. When the present invention is used, there will generally be air in the needle tube of the syringe. At this time, the air will enter the ink supply channel before the ink, and then the ink will enter. With the movement of the buffer piston, the air will enter the exhaust channel through the connecting hole and then be discharged. With the addition of ink, the ink will also be discharged through the exhaust channel. When adding ink, if ink is found to be flowing out, the sealing cap can be screwed on immediately. The outflow of ink means that all the air has been discharged. When the addition of ink is stopped, the buffer piston will reset. At this time, a section of ink will be retained in the slide tube, thereby forming a water seal effect to prevent external air from entering. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Please refer to Figures 1 - 3 , in the embodiment of the present invention, a cartridge structure of an inkjet printer includes a housing 1. A contact piece 2 for connecting to a host is fixedly connected to the side wall of the housing 1. A nozzle is also fixedly connected to the lower end of the housing 1, and the nozzle is connected to the contact piece 2. Specifically, the contact piece 2 and the nozzle are both prior arts, and the specific connection relationship and functions are not described in detail herein;

[0036] A top cover 3 is snap-fitted to the upper end of the housing 1. A storage bin 5 is also snap-fitted inside the housing 1. A bin cover 7 is snap-fitted to the upper end of the storage bin 5. Specifically, an ink groove is opened at the bottom end inside the housing 1, and the ink groove corresponds to the nozzle. A partition is provided at the upper end of the ink groove, and a filter port 100 is opened on the partition. A filter membrane for filtering ink is provided in the filter port 100. More specifically, an ink supply port is provided at a position corresponding to the filter port 100 at the lower end of the storage bin 5, so as to facilitate the ink in the storage bin 5 to smoothly enter the ink groove;

[0037] A sponge 8 for slowly releasing ink is filled inside the storage bin 5. Specifically, the slow release here means slowly supplying ink to the ink groove to prevent the nozzle from ejecting too much ink at one time. At the same time, the sponge 8 can also adsorb ink through capillary action to avoid leakage of liquid ink due to gravity or shaking; at the same time, the sponge 8 can also slow down the evaporation rate of the ink and maintain the stability of the humidity inside the cartridge. Through the process of absorbing and releasing ink, the sponge 8 forms a stable negative pressure environment to prevent the ink from directly flowing to the nozzle due to gravity, causing ink leakage or nozzle blockage;

[0038] Please refer to Figure 4 , Figure 5 and Figure 10, the right end of the storage bin 5 is movably connected with a continuous ink supply structure 6, specifically, the front and rear ends of the ink cartridge 600 are fixedly connected with a slide plate 601, and the inner wall of the shell 1 is symmetrically fixedly connected with a slide groove for stable sliding of the slide plate 601, and the continuous ink supply structure 6 includes an ink cartridge 600, and the end of the ink cartridge 600 close to the storage bin 5 is symmetrically fixedly connected with two docking sleeves 710 for conveying ink, and the end of the storage bin 5 close to the ink cartridge 600 is symmetrically fixedly connected with two docking ports 712, and the docking ports 712 are inserted in the docking sleeve 710, and the docking sleeve 710 is also fixedly connected with a second anti-reverse sleeve 711 to prevent ink leakage, specifically, the outer diameter of the docking port 712 is smaller than the outer diameter of the docking sleeve 710, and the end of the docking port 712 close to the docking sleeve 710 is provided with a chamfer;

[0039] The ink storage cartridge 600 is fixedly connected with an ink filling tube 707, and a first anti-reversal sleeve 708 is arranged inside the ink filling tube 707 to prevent ink from overflowing. The ink in the conventional ink storage cartridge 600 is filled once and cannot be filled continuously by itself, and frequent ink changes are required. In the present application, in order to allow the ink in the ink storage cartridge 600 to continuously flow into the storage bin 5, an ink supply piston 700 for pushing the ink to flow into the storage bin 5 is slidably connected inside the ink storage cartridge 600. In order to further ensure the stability of the ink supply piston 700, a sliding tube 701 is also fixedly connected inside the ink storage cartridge 600. The ink supply piston 700 is slidably sleeved on the outside of the sliding tube 701, and the ink filling tube 707 is fixedly connected to the sliding tube 701.

[0040] When adding ink in a traditional way, some air will enter the storage bin 5, and the air entering the storage bin 5 will affect the inkjet of the nozzle, and even cause the ink to be unable to be sprayed. For this reason, an ink supply channel is provided in the slide tube 701, and the end of the slide tube 701 away from the storage bin 5 passes through the ink storage cartridge 600, and the end of the slide tube 701 located at the ink storage cartridge 600 is threadedly connected with a blocking cap 704, the ink supply channel is connected with the ink adding tube 707, and an exhaust channel 703 is also provided inside the slide tube 701, the exhaust channel 703 is located outside the ink supply channel, and a connecting hole is provided between the ink supply channel and the exhaust channel 703, specifically, the exhaust channel 703 is connected to the external space, and the end of the ink supply channel away from the storage bin 5 is in a blocked state;

[0041] The ink supply channel is also slidably connected to a buffer piston 705, and one end of the buffer piston 705 away from the blocking cover 704 is fixedly connected to a support spring 706. The outer wall of the sliding tube 701 is also provided with an ink inlet 702. Figure 10As shown, the ink inlet 702 is located on the left side of the communication hole. When injecting ink into the ink filling tube 707 using a syringe, there is generally air in the syringe needle tube (and there is also air in the ink filling tube 707). At this time, the air will enter the ink supply channel before the ink, and then the ink will enter. At this time, the air and the ink will together push the buffer piston 705 to compress the support spring 706. As the buffer piston 705 moves, the air will enter the exhaust channel 703 through the communication hole and then be discharged. As the ink is added, the ink will also be discharged through the exhaust channel 703. When ink flows out during ink filling, the sealing cap 704 can be immediately screwed on. The ink flowing out means that all the air has been discharged. At this time, continuously pushing the ink can make the ink continue to squeeze the buffer piston 705 and then enter the ink storage box 600 through the ink inlet 702 to complete ink filling, and at the same time, it can also prevent air from entering the ink storage box 600. At the same time, when ink filling stops, the buffer piston 705 will reset, and at this time, a section of ink will remain in the sliding tube 701 to form a water seal effect to prevent external air from entering.

[0042] Embodiment 2:

[0043] Please refer to Figures 4 - 9 , on the basis of Embodiment 1, pressure tubes 602 and pressure supply tubes 603 for ensuring the stable movement of the ink supply piston 700 are fixedly connected to both the front and rear ends of the ink storage box 600. More specifically, the pressure supply tube 603 is located above the pressure tube 602, and the pressure supply tube 603 and the pressure tube 602 are respectively provided as two;

[0044] A pressure piston 608 is slidably connected inside the pressure tube 602. One end of the pressure piston 608 close to the storage bin 5 is fixedly connected to a piston rod 607, and the piston rod 607 is fixedly connected to the outer wall of the storage bin 5. When the ink storage box 600 does not slide out of the housing 1, the pressure piston 608 is located on the right side inside the pressure tube 602 (taking Figure 6 as a reference);

[0045] The pressure tube 602 is connected to the ink storage box 600 through a first one-way tube 604. Specifically, a one-way valve is provided inside the first one-way tube 604, and the first one-way tube 604 only allows air in the ink storage box 600 to flow into the pressure tube 602;

[0046] The pressure tube 602 is connected to the pressure supply tube 603 through a second one-way tube 605. A one-way valve is also provided inside the second one-way tube 605, and the second one-way tube 605 only allows air in the pressure tube 602 to enter the pressure supply tube 603;

[0047] The pressure supply tube 603 is connected to the ink storage box 600 through a third one-way tube 606. Specifically, a one-way valve is also provided inside the third one-way tube 606, and the third one-way tube 606 only allows air in the pressure supply tube 603 to enter the ink storage box 600;

[0048] The pressure supply pipe 603 is internally slidably connected with a pressure supply piston 613. In order to prevent the pressure supply piston 613 from sliding too fast, causing the ink supply piston 700 in the ink cartridge 600 to slide too fast, causing the ink to accelerate into the storage bin 5 within a period of time and causing the ink to overflow from the nozzle, a continuous pushing structure for decelerating the pressure supply piston 613 is installed inside the pressure supply pipe 603. Specifically, in order to ensure that the pressure supply piston 613 can stably slide in the pressure supply pipe 603, a semicircular protrusion is fixedly connected to the outer wall of the pressure supply piston 613, and an arc-shaped groove corresponding to the semicircular protrusion is opened on the inner wall of the pressure supply pipe 603. The semicircular protrusion and the arc-shaped groove are tightly fitted and lubricating oil is applied between the two. The lubricating oil can ensure the stable sliding of the pressure supply piston 613 and also play a sealing role.

[0049] Please refer to Figures 7 - 9 , the continuous pushing structure includes a protective sleeve 609 fixedly connected to the inside of the pressure supply pipe 603. Specifically, the protective sleeve 609 is fixed to one end of the pressure supply pipe 603 close to the storage bin 5. A rifle sleeve 610 is fixedly connected to the inside of the protective sleeve 609. A rifle rod 611 is connected to the inside of the rifle sleeve 610 (the connection relationship between the rifle sleeve 610 and the rifle rod 611 is the prior art and will not be described in detail herein). The rifle rod 611 is made of iron material, and an electromagnet 622 and a force storage spring 621 are also fixedly connected to the inside of the protective sleeve 609. A threaded rod 612 is threadedly connected to the inside of the rifle rod 611. One end of the threaded rod 612 close to the pressure supply piston 613 is rotatably connected to the pressure supply piston 613.

[0050] One end of the pressure supply piston 613 close to the rifle rod 611 is fixedly connected to a fixed gear ring 614, and a positioning gear ring 615 is rotatably connected inside the fixed gear ring 614. A speed reduction cover 616 is fixedly connected to the side of the positioning gear ring 615 close to the rifle rod 611, and the speed reduction cover 616 is connected to the fixed gear ring 614 through a one-way bearing. Specifically, the one-way bearing allows the positioning gear ring 615 to only rotate in one direction on one side of the fixed gear ring 614. A spring spring 620 is installed inside the speed reduction cover 616, and one end of the spring spring 620 is fixedly connected to the speed reduction cover 616, and the other end is fixedly connected to the rifle rod 611. A positioning frame 618 is fixedly connected to the outer wall of the threaded rod 612, and three transition gears 619 are rotatably connected to the outer wall of the positioning frame 618. The transition gear 619 is located between the meshing of the positioning gear ring 615 and the fixed gear ring 614, and meshes with the positioning gear ring 615 and the fixed gear ring 614.

[0051] The fixed ring at one end of the positioning gear ring 615 away from the fixed gear ring 614 is connected to a speed reduction cover 616, and a plurality of speed reduction plates 617 are fixedly connected to the outer wall of the speed reduction cover 616. When the positioning gear ring 615 rotates, it will drive the speed reduction cover 616 and the speed reduction plates 617 to rotate. At this time, the speed reduction plates 617 will generate resistance to the positioning gear ring 615 under the action of air resistance, thereby reducing the speed (the speed reduction plates 617 can only play a partial speed reduction effect).

[0052] Embodiment three:

[0053] Please refer to Figures 11 - 13 Based on Example 1, the first anti-reverse sleeve 708 is set to be funnel-shaped and made of rubber material, and a flat opening 709 is set at the lower end of the first anti-reverse sleeve 708. The design of the flat opening 709 allows the pressure of the ink accumulated at the opening of the ink filling tube 707 to squeeze the flat opening 709 when the ink flows back upward, thereby closing the flat opening 709 to prevent the ink from overflowing;

[0054] The second anti-reverse sleeve 711 is set to be funnel-shaped and made of rubber material. A pull rope 713 is passed through the inside of the second anti-reverse sleeve 711. The outer diameter of the pull rope 713 is larger than the minimum diameter of the second anti-reverse sleeve 711, that is, the pull rope 713 can block the second anti-reverse sleeve 711, and the pull rope 713 is made of cotton material. One end of the pull rope 713 passes through the storage bin 5 through the docking port 712, and the end of the pull rope 713 located in the storage bin 5 is fixedly connected to a counterweight block 715 for facilitating the resetting of the pull rope 713, and the end of the pull rope 713 located in the ink cartridge 600 is fixedly connected to a blocking ball 714, which can prevent the pull rope 713 from detaching from the second anti-reverse sleeve 711.

[0055] The working principle of the present invention is:

[0056] When the present invention is used, the side cover 4 is opened, and then the ink cartridge 600 is pulled outward, at which time the piston rod 607 pulls the pressurizing piston 608 to move and then draw air from the ink cartridge 600 (when the ink cartridge 600 is not in use, the ink supply piston 700 is located at the side close to the storage bin 5). As the air is drawn out, the pressure on one side of the ink supply piston 700 in the ink cartridge 600 decreases, and then the ink supply piston 700 moves to the side away from the storage bin 5 to reset;

[0057] When adding ink, the syringe head with ink drawn is inserted into the ink adding tube 707. As the ink enters, the ink will flow into the ink storage cartridge 600. At the same time, the design of the slide tube 701 and the exhaust channel 703 can prevent air from entering the ink storage cartridge 600. Since the pull rope 713 blocks the second anti-reverse sleeve 711, the ink in the ink storage cartridge 600 will not flow out from the docking sleeve 710.

[0058] After the ink is added, the ink cartridge 600 is pushed inwards. At this time, the air in the pressurized tube 602 will enter the pressure supply tube 603. At this time, the air will push the pressure supply piston 613 to move in the direction close to the storage bin 5, and at this time, the rifle rod 611 will also move in the direction close to the storage bin 5. When the rifle rod 611 moves, it will rotate in a straight line under the action of the rifle sleeve 610. At this time, the one-way bearing between the positioning gear ring 615 and the fixed gear ring 614 is in a state of being unable to rotate. At this time, when the rifle rod 611 rotates, it will tighten the clockwork spring 620. When the gas in the pressurized tube 602 all enters the pressure supply tube 603, the air will push the pressure supply piston 613 to move in the direction close to the storage bin 5. At this time, the rifle rod 611 will also move in the direction close to the storage bin 5. When the rifle rod 611 moves, it will rotate in a straight line under the action of the rifle sleeve 610. At this time, the one-way bearing between the positioning gear ring 615 and the fixed gear ring 614 is in a state of being unable to rotate. At this time, when the rifle rod 611 rotates, it will tighten the clockwork spring 620. When the rifle rod 611 is in the tube 603, the rifle rod 611 contacts the electromagnet 622, and the electromagnet 622 triggers and attracts the rifle rod 611 (in this application, only the known function of the electromagnet 622 that can adsorb iron materials is used. Therefore, the existing function of the electromagnet 622 and the related circuit are not described in detail here. Secondly, a pressure switch is provided at the end of the electromagnet 622. When the rifle rod 611 triggers the pressure switch, the electromagnet 622 can be turned on. Similarly, the pressure switch is also a prior art and is not disclosed in detail here). At this time, it also indicates that the ink cartridge 600 is reset, and then the ink filling operation can be completed by covering the side cover 4;

[0059] When the ink cartridge 600 is reset, the docking sleeve 710 will be sleeved on the outside of the docking port 712, and the docking port 712 will open the second anti-reversal sleeve 711, and the ink in the ink cartridge 600 will automatically flow into the storage bin 5 under the guidance of the pull rope 713 (the ink will permeate the pull rope 713, and since the storage bin 5 is equipped with a sponge 8, the sponge 8 will absorb the ink on the surface of the pull rope 713, so the ink will slowly flow into the storage bin 5 even without a power source);

[0060] After the ink storage cartridge 600 enters, the post-pressure piston 613 no longer drives the rack lever 611 to move, that is, the rack lever 611 no longer winds the clockwork spring 620. At this time, the clockwork spring 620 begins to release energy, and at this time, the fixed gear ring 614 begins to rotate (initially, the rotation direction of the rack lever 611 is opposite to the release direction of the one-way bearing, so the fixed gear ring 614 is in a locked state when the rack lever 611 rotates). When the fixed gear ring 614 rotates, it will drive the positioning gear ring 615 to rotate, and when the positioning gear ring 615 rotates, it will drive a number of intermediate gears 619 to rotate. At this time, since the fixed gear ring 614 does not rotate, when the number of intermediate gears 619 rotates, it will drive the threaded rod 612 to rotate through the positioning bracket 618, and the rotation speed of the threaded rod 612 is less than the rotation speed of the positioning gear ring 615 (specifically, the reduction gear ratio relationship, which will not be described in detail here). Therefore, at this time, the threaded rod 612 will slowly move outward from the rack lever 611 under the action of the thread, thereby pushing the post-pressure piston 613 to move, so that the air in the supply pressure tube 603 enters the ink storage cartridge 600 to push the ink supply piston 700 to move. As the ink supply piston 700 moves, the ink can be pushed into the storage bin 5. Since the threaded rod 612 moves slowly, the ink also slowly enters the storage bin 5. In this way, it is possible to avoid damage to the internal structure of the sponge 8 caused by too fast ink addition, and to avoid ink spraying from the nozzle and causing secondary pollution. When the ink in the storage bin 5 is full, the ink in the ink storage cartridge 600 cannot enter. At this time, the energy of the clockwork spring 620 cannot be released, and the ink supply can be stopped. When the ink in the storage bin 5 decreases, the ink supply can be restored, thereby completing continuous ink addition (this effect can select the energy storage of the clockwork spring 620 according to the pressure that the nozzle can withstand, and the energy release of the clockwork spring 620 is gradually decreasing. Therefore, controlling the initial energy of the clockwork spring 620 can complete the corresponding operation);

[0061] When the threaded rod 612 stops rotating, it means that the post-pressure piston 613 stops working. At this time, the electromagnet 622 is turned off, and the energy stored in the spring 621 is released to push the rack lever 611 to reset. At this time, the rack lever 611 rotates and will re-sleeve on the outside of the threaded rod 612, and at this time, the rotation direction of the rack lever 612 is opposite to the initial rotation direction, that is, the fixed gear ring 614 will also rotate, and the threaded rod 612 will also rotate, thereby quickly resetting the rack lever 611 (the number of threads of the rack lever 611 and the threaded rod 612 needs to be calculated and allocated according to the actual situation).

[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
