Description

Technical Field

[0001] This utility model relates to the field of printer technology, specifically to a printer toner cartridge that is easy to refill with toner. Background Technology

[0002] What we commonly call a "toner cartridge" is actually a toner cartridge. Toner is a solid powder. Toner cartridges are a type of copier and laser printer consumable. Before use, toner needs to be filled into the toner cartridge.

[0003] In the prior art, patent CN202323415885.5 discloses a toner cartridge that is easy to add toner, including a toner cartridge body, the surface of the cover body and the inner wall of the connecting plate are provided with a mechanism for easy addition, the surface of the toner compartment body and the shelf are both provided with a mechanism for easy disassembly and assembly, and the surface of the shelf is provided with an anti-static mechanism.

[0004] The aforementioned toner cartridges only optimize the structure for disassembling and assembling the toner cartridges when actually adding toner. When filling toner, it is still necessary to manually hold the toner bottle and apply pressure to the toner bottle by pouring, tapping, and squeezing to pour the toner from the bottle into the toner cartridge through the feed inlet. This step has not been simplified and still has the problem of cumbersome operation. Therefore, we propose a printer toner cartridge that is easy to fill with toner. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a printer toner cartridge that is easy to fill with toner and is very simple to operate, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printer toner cartridge that is easy to fill with toner, comprising a cartridge body, a toner holding mechanism, and a quick filling mechanism;

[0007] Powder holding mechanism: It includes a holding cylinder, which is fixedly connected to the inside left side of the box body;

[0008] The quick-filling mechanism includes an internal pull rod, a sealing ring, a first spiral blade, a second spiral blade, a thrust block, and an external pull rod. The sealing ring is fixedly connected to the middle of the right side wall of the container. The internal pull rod is movably sleeved on the inner arc surface of the sealing ring. The first spiral blade is evenly distributed on the left side of the outer arc surface of the internal pull rod, and the second spiral blade is located on the left side of the internal pull rod. The thrust block is fixedly connected to the right end of the internal pull rod, and the external pull rod is fixedly connected to the right end of the thrust block. The operation is very simple.

[0009] Furthermore, the rapid filling mechanism also includes a rod rotation drive assembly, which includes a spiral groove, a hole-type mounting seat, and a top ball. The spiral groove is formed on the outer arc surface of the external pull rod. The hole-type mounting seat is fixedly connected to the right side wall of the box. The outer arc surface of the external pull rod is movably sleeved with the middle of the hole-type mounting seat. A top ball is fixedly connected to the upper side of the inner arc surface of the hole-type mounting seat. The outer arc surface of the top ball is slidably connected to the inside of the spiral groove, providing guiding force for the rotation of the pull rod.

[0010] Furthermore, the rapid filling mechanism also includes a push-pull block and a limiting rod. The push-pull block is rotatably connected to the right end of the external pull rod. The four corners of the side of the hole-shaped mounting base are slidably connected with evenly distributed limiting rods. The right ends of the four limiting rods are fixedly connected to the left side of a push-pull block to restrict the position of the push-pull block and prevent it from rotating.

[0011] Furthermore, a pull ring is fixedly connected to the right side wall of the push-pull block to enable manual pulling.

[0012] Furthermore, the powder holding mechanism also includes a discharge port, a feed port, an internal thread, and an external thread. The discharge port is located on the left side of the holding cylinder, the feed port is located on the upper side of the outer arc surface of the holding cylinder, the feed port is located on the upper side of the outer arc surface, and the feed port is located on the upper side of the inner arc surface, thereby realizing the function of feeding and discharging materials.

[0013] Furthermore, it also includes a toner bottle, which is located outside the toner cartridge. The bottle opening of the toner bottle is provided with an external screw thread, and the outside of the toner bottle is provided with a sealing cap. The lower side of the inner arc surface of the sealing cap is provided with an internal screw thread to realize the function of screwing the toner bottle and prevent toner leakage during the filling process.

[0014] Furthermore, the lower surface of the housing is provided with evenly distributed docking seats, which can be used to dock and install the toner cartridge.

[0015] Furthermore, an air vent is provided on the upper center of the inner arc surface of the container, and a uniformly distributed polyester fiber filter layer is provided inside the air vent to maintain stable air pressure inside the container.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This printer toner cartridge, which is easy to refill, has the following advantages:

[0017] Utilizing the limiting effect of the spiral groove, the internal pull rod moves left and right while also rotating clockwise and counterclockwise, thus conveying the toner that has fallen into the container in batches from the toner bottle to the left. The operator only needs to screw the toner bottle on and pull the ring repeatedly to quickly complete the toner cartridge filling operation, which is very convenient. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This embodiment provides a technical solution: a printer toner cartridge that is easy to fill with toner, including a cartridge body 1, characterized in that: a toner holding mechanism 2 and a quick filling mechanism 3;

[0025] Toner holding mechanism 2: It includes a holding cylinder 21, which is fixedly connected to the inside left side of the housing 1. The toner holding mechanism 2 also includes a discharge port 22, a feed port 23, an internal thread 24, and an external thread 25. The discharge port 22 is located on the left side of the holding cylinder 21. The feed port 23 is provided on the upper side of the outer arc surface of the holding cylinder 21. The upper side of the outer arc surface of the feed port 23 is provided with an external thread 25, and the upper side of the inner arc surface of the feed port 23 is provided with an internal thread 24. It also includes a toner bottle 6, containing toner. Bottle 6 is located outside the toner cartridge. The bottle opening of toner bottle 6 has an external thread for screwing in. A sealing cap 7 is located on the outside of toner bottle 6. The lower side of the inner arc surface of the sealing cap 7 has an internal thread for screwing in. (The sealing cap 7 is threadedly connected to the external thread 25 of the inlet 23 via the internal thread for screwing in, thus sealing the container 21. Toner bottle 6 is threadedly connected to the internal thread 24 of the inlet 23 via the external thread for screwing in, thus allowing the toner bottle 6 to be installed when pouring toner.) The lower surface of the cartridge body 1 has... The evenly distributed docking seat 5 has a vent 8 located in the middle of the upper side of the inner arc surface of the holding cylinder 21. The vent 8 has an evenly distributed polyester fiber filter layer 9 inside. When the toner cartridge is needed, the toner cartridge and toner bottle 6 can be manually picked up. Then, the external thread of the toner bottle 6 is screwed into the internal thread 24 of the feed port 23. The toner cartridge is then inverted. Due to gravity, when the toner bottle 6 is inverted, some toner enters the holding cylinder 21 from the feed port 23. The capacity of the toner bottle 6 is the same as the capacity of the holding cylinder 21. When the toner in the toner bottle 6 is used up, it means that the holding cylinder 21 is full of toner. The toner entering the holding cylinder 21 will displace the air inside. At this time, the excess air will be discharged through the vent 8. During this process, the polyester fiber filter layer 9 (the polyester fiber filter layer 9 is formed by multiple layers of polyester fibers stacked together) filters out the toner and only discharges the air.

[0026] The rapid filling mechanism 3 includes an internal pull rod 31, a sealing ring 32, a first spiral blade 33, a second spiral blade 34, a thrust block 35, and an external pull rod 36. The sealing ring 32 is fixedly connected to the middle of the right side wall of the container 21. The inner arc surface of the sealing ring 32 is movably sleeved with the internal pull rod 31 (the sealing ring 32 is a Y-type polyurethane rubber sealing ring). The left side of the outer arc surface of the internal pull rod 31 is provided with evenly distributed first spiral blades 33, and the left side of the internal pull rod 31 is provided with second spiral blades 34. The right end of the internal pull rod 31 is fixedly connected to the thrust block 35, and the right end of the thrust block 35 is fixedly connected to the external pull rod 36. The rapid filling mechanism 3 also includes a rod rotation drive assembly 37, which includes a spiral groove 371, a hole-type mounting seat 372, and a top ball 373. The spiral groove 371 is formed on the outer arc surface of the external pull rod 36. A hole-type mounting seat 372 is fixedly connected to the right side wall of the box body 1. The outer arc surface of the external pull rod 36 is movably sleeved with the middle of the hole-type mounting seat 372. A top ball 373 is fixedly connected to the upper side of the inner arc surface of the hole-type mounting seat 372. The outer arc surface of the top ball 373 is slidably connected to the inside of the spiral groove 371. The quick filling mechanism 3 also includes a push-pull block 38 and a limiting rod 39. The push-pull block 38 is rotatably connected to the right end of the external pull rod 36. The four corners of the side of the hole-type mounting seat 372 are slidably connected with evenly distributed limiting rods 39. The right ends of the four limiting rods 39 are fixedly connected to the left side of a push-pull block 38. A pull ring 4 is fixedly connected to the right side wall of the push-pull block 38 (a bearing seat, specifically model SK6, is provided in the middle of the left side wall of the push-pull block 38).The 8-SHF bracket bearing seat has its inner bearing ring fixedly connected to the right side of the outer arc surface of the external pull rod 36, maintaining a rotational connection between the external pull rod 36 and the push-pull block 38. Then, the pull ring 4 is manually and continuously pulled, causing the push-pull block 38 to reciprocate left and right. During the pushing process, the spiral groove 371 and the top ball 373 maintain a sliding connection, and the central axis of the spiral groove 371 coincides with the central axis of the external pull rod, thus causing the top ball 373 to press tightly against the spiral groove. The inner arc surface of 371 causes the outer pull rod 36 to rotate clockwise as it moves to the left, which in turn drives the first spiral blade 33 and the second spiral blade 34 to rotate clockwise and move to the left. This continuously pushes the toner that has entered the container 21 to the left. When the inner pull rod 31 moves to the far left, the pull ring 4 can be pulled out. At this time, the outer pull rod 36 rotates counterclockwise as it moves to the right. The spiral conveying direction of the first spiral blade 33 and the second spiral blade 34 is clockwise. When the first spiral blade 33 and the second spiral blade 34 move counterclockwise to the right, they will not carry the toner already fed into the left side of the container 21 to the right side. When the rightmost first spiral blade 33 touches the right side wall of the container 21, the pull ring 4 is stopped, and the pushing operation is repeated to continue feeding some toner to the right side. This pushing and pulling motion is repeated continuously. During this period, the toner that continuously falls into the container 21 from the toner bottle 6 is pushed to the left side until the filling is completed. During the repeated pushing and pulling motion, the toner will gradually... As the toner cartridge 21 is gradually filled, the first spiral blade 33 and the second spiral blade 34 move to the right and touch the already filled toner, increasing the resistance. Therefore, the length of each push-pull reciprocating motion varies, exhibiting a pattern of gradually increasing frequency and gradually decreasing length, until the toner cartridge 21 is completely filled. At this point, the toner bottle 6 will also be empty. Unscrew the toner bottle 6 and screw the sealing cap 7 onto the external thread 25. The toner cartridge can then be installed onto the drum unit via the docking seat 5, completing the filling process.

[0027] The working principle of the printer toner cartridge provided by this utility model for easy toner filling is as follows: When the toner cartridge is needed, the toner cartridge and toner bottle 6 can be manually picked up, and then the external thread of the toner bottle 6 is screwed into the internal thread 24 of the feed port 23. Then, the toner cartridge is inverted. Due to gravity, when the toner bottle 6 is inverted, some toner enters the holding cylinder 21 from the feed port 23. Then, the pull ring 4 is manually pulled repeatedly, which drives the push-pull block 38 to move back and forth. During the process of pushing the push-pull block 38, the spiral groove 371 and the top ball 3... 73. The sliding connection is maintained in real time, and the central axis of the spiral groove 371 coincides with the central axis of the external pull rod. This causes the top bead 373 to press against the inner arc surface of the spiral groove 371, causing the external pull rod 36 to rotate clockwise as it moves to the left. This drives the first spiral blade 33 and the second spiral blade 34 to rotate clockwise and move to the left, thus continuously piling the toner that has entered the container 21 to the left. When the internal pull rod 31 moves to the leftmost position, the pull ring 4 can be pulled out. At this time, the external pull rod 36 rotates counterclockwise as it moves to the right. As the clock hands rotate, the first spiral blade 33 and the second spiral blade 34 rotate clockwise. Therefore, when the first spiral blade 33 and the second spiral blade 34 move counterclockwise to the right, they will not carry the toner already fed into the left side of the container 21 to the right side. When the rightmost first spiral blade 33 touches the right side wall of the container 21, the pull ring 4 stops being pulled, and the pushing operation is repeated to continue conveying some toner to the right side. This pushing and pulling motion is repeated continuously. During this period, the toner that continuously falls from the toner bottle 6 into the container 21 is pushed to the left side until the filling is completed. During the repeated pushing and pulling motion, the toner will gradually fill the inside of the container 21. The first spiral blade 33 and the second spiral blade 34 will touch the already filled toner when they move to the right, and the resistance will increase accordingly. Therefore, the length of each push and pull reciprocating motion is different, showing a motion pattern of gradually increasing frequency and gradually decreasing length, until the container 21 is filled with toner. At this time, the toner bottle 6 will also be used up. Then, unscrew the toner bottle 6 and screw the sealing cap 7 onto the external thread 25. At this time, the toner cartridge can be installed onto the drum unit through the docking seat 5 to complete the filling operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
