Description
Technical Field
[0001] This utility model relates to the field of powder box technology, and in particular to a powder box with moisture-proof function. Background Technology
[0002] Toner cartridges, also known as drum units or powder cartridges, are the core components in laser printers, copiers, and other equipment used to store and supply toner. They may also integrate other key components such as the photosensitive drum, charging roller, and developing roller. They are a combination of the "ink cartridge" and part of the imaging mechanism in the laser printing process, directly affecting print quality and equipment stability.
[0003] As disclosed in CN216083412U, this utility model belongs to the field of toner cartridge technology and discloses a toner cartridge structure with good moisture-proof function. It includes a toner cartridge body, with a toner drum connected to the left end of the body. A moisture-proof cavity, a stirring cavity, and a connecting groove are formed in the middle of the toner cartridge body. A stirring shaft is fixedly installed inside the stirring cavity, and a stirring plate is fixedly installed on the surface of the stirring shaft. This utility model is powered by connecting to the front end of a terminal block. When the ball screw rotates, it drives the insertion rod to move back and forth above the lifting plate through a meshing plate, causing the insertion rod to agitate the toner. Simultaneously, the terminal block supplies power to the ball screw, and the heating rod inside the ball screw generates heat, which is then conducted to the insertion rod through the meshing plate. This allows the insertion rod to agitate the toner while simultaneously heating and drying it, thus achieving the moisture-proof effect of the device.
[0004] In the prior art, when the ball screw rotates, it drives the insertion rod to move. The insertion rod agitates the toner, and the heating rod inside the ball screw generates heat to heat and dry the toner, achieving the moisture-proof effect of the device. However, when the toner is dried at high temperature, static electricity is generated in the toner box. When the stirring structure is stirred, the toner will adhere to the stirring structure due to static electricity, resulting in more and more toner accumulating on the stirring surface. Eventually, the toner on the stirring rod will clump and solidify, ultimately affecting the stirring effect. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the prior art where, when toner is dried at high temperature, static electricity is generated in the toner box. During stirring, the toner adheres to the stirring structure due to static electricity, causing more and more toner to accumulate on the stirring surface. Eventually, the toner on the stirring rod clumps and solidifies, ultimately affecting the stirring effect.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a toner cartridge with a moisture-proof function, comprising a toner cartridge body, a stirring component disposed on one side of the interior of the toner cartridge body, a feeding component disposed on one side of the toner cartridge body located on the stirring component, a drying component disposed at the top of the stirring component inside the toner cartridge body, an installation groove being formed at the top of one side of the toner cartridge body, a first latching cover being rotatably connected to the toner cartridge body located inside the installation groove, a snap-fit groove being formed at the top of the first latching cover, and four latching rods being fixedly connected to the four corners of the first latching cover near the toner cartridge body, the latching rods engaging with the toner cartridge body.
[0007] In a preferred embodiment, the stirring assembly includes a stirring chamber fixed to one side inside the toner cartridge body. Rotary rods are rotatably connected at equal intervals to the top of the stirring chamber, penetrating the stirring chamber. A first striking plate is fixedly connected to one end of the rotary rod inside the stirring chamber. A worm gear is fixedly connected to the top of the rotary rod, and a worm is engaged on one side of the worm gear. The worm is rotatably connected to the toner cartridge body, with one end penetrating the toner cartridge body. A motor is drively connected to the penetrating end of the worm, and the motor is fixedly mounted to the toner cartridge body.
[0008] In a preferred embodiment, a stirring rod is rotatably connected to the middle of the bottom of the stirring chamber. One end of the stirring rod passes through the stirring chamber and the toner cartridge body. Stirring blades are fixedly connected to the stirring rod at equal intervals at one end inside the stirring chamber. The first striking plate is located on the side where the rotating rods are close to each other, and the first striking plate abuts against the rotating rods.
[0009] In a preferred embodiment, the feeding assembly includes a powder feeding bin, which is fixedly connected to the toner cartridge body and the mixing bin. A feeding pipe is fixedly connected to the middle of the top of the powder feeding bin, and the feeding pipe is fixedly connected through the toner cartridge body. A discharge port is opened at the bottom of the powder feeding bin near the mixing bin, and the discharge port communicates with the mixing bin. A lead screw is rotatably connected to the middle of the powder feeding bin. One end of the lead screw passes through the powder feeding bin and the toner cartridge body. A feeding plate is threadedly connected to the end of the lead screw inside the powder feeding bin. The feeding plate is slidably connected to the powder feeding bin. A heating tube is rotatably connected inside the lead screw.
[0010] In a preferred embodiment, springs are fixedly connected at equal intervals on both sides of the top of the powder filling hopper, and a second striking plate is fixedly connected to the bottom of the springs, the second striking plate abutting against the material feeding plate.
[0011] In a preferred embodiment, the drying assembly includes a drying box, which is slidably connected inside the toner cartridge body at the top of the mixing chamber. The drying box is slidably connected to the mounting groove. Ventilation holes are equidistantly arranged on one side of the drying box. A second cover is rotatably connected to the top of the drying box. A drying block is snapped into the inside of the drying box.
[0012] The beneficial effects of this utility model are as follows:
[0013] In this invention, the rotation of the stirring rod drives the stirring blade to rotate, and the stirring blade stirs the incoming carbon powder. Some of the carbon powder adheres to the stirring rod and stirring blade due to static electricity. The motor is started to drive the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the rotating rod to rotate, and the rotating rod drives the first striking plate to rotate. The first striking plate strikes the rotating stirring blade, causing the stirring blade to vibrate. The stirring blade also drives the stirring rod to vibrate, and the carbon powder adhering to the surface of the stirring rod and stirring blade is shaken off, thus avoiding the carbon powder on the stirring rod from clumping and affecting the stirring.
[0014] As the lead screw rotates, it drives the feeding plate to move. While the feeding plate moves the toner, it heats the toner in the toner hopper through the heating tube to prevent the toner box from getting damp. When the feeding plate moves, it comes into contact with the second striking plate. The second striking plate gradually tilts and eventually separates from the feeding plate. At the moment of separation, the second striking plate swings laterally through the elasticity of the spring, thus colliding with the feeding plate. Therefore, the feeding plate is vibrated, causing the toner adhering to the feeding plate to be shaken off.
[0015] The operator engages the latch, causing the first cover to pull against the lever, which then pulls the lever out of the toner cartridge body. At this point, the first cover opens. The operator then inserts the drying box into the mounting slot, positioned at the top of the mixing chamber. This allows the drying block to dry the air inside the toner cartridge body. The operator then snaps the first cover back on, and the lever engages with the toner cartridge body. The first cover shields the drying box, improving its stability and preventing the drying component from only drying the toner and failing to dry the rest of the space inside the toner cartridge.

[0024] 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.
[0025] Please see Figure 1 - Figure 3 This utility model provides a technical solution: a toner cartridge with a moisture-proof function, including a toner cartridge body 1, a stirring component is provided on one side of the interior of the toner cartridge body 1, a feeding component is provided on one side of the toner cartridge body 1 located on the stirring component, a drying component is provided at the top of the stirring component inside the toner cartridge body 1, an installation groove 12 is provided at the top of one side of the toner cartridge body 1, a first cover 11 is rotatably connected to the toner cartridge body 1 located inside the installation groove 12, a snap-fit groove 111 is provided at the top of the first cover 11, and four corners of the first cover 11 near the toner cartridge body 1 are fixedly connected to the four corners, and the snap-fit rods 112 are engaged with the toner cartridge body 1.
[0026] like Figure 2 and Figure 4As shown, the stirring assembly includes a stirring chamber 21, which is fixed inside the toner cartridge body 1 on one side. Rotating rods 27 are rotatably connected at equal intervals at the top of the stirring chamber 21, and the rotating rods 27 penetrate the stirring chamber 21. A first striking plate 28 is fixedly connected to one end of the rotating rods 27 inside the stirring chamber 21. A worm gear 26 is fixedly connected to the top of the rotating rods 27. A worm 25 is meshed on one side of the worm gear 26. The worm 25 is rotatably connected to the toner cartridge body 1, and one end of the worm 25 penetrates the toner cartridge body 1. A motor 24 is drivenly connected to the penetrating end of the worm 25. The motor 24 is fixedly installed to the toner cartridge body 1. A stirring rod 22 is rotatably connected to the middle of the bottom of the stirring chamber 21. One end of the stirring rod 22 penetrates the stirring chamber 21 and the toner cartridge body 1. Stirring blades 23 are fixedly connected at equal intervals at one end of the stirring rod 22 inside the stirring chamber 21. The first striking plate 28 is located on the side of the rotating rods 27 that are close to each other, and the first striking plate 28 abuts against the rotating rods 27.
[0027] In this embodiment, the rotation of the stirring rod 22 drives the stirring blade 23 to rotate. The stirring blade 23 stirs the incoming toner powder, and some of the toner powder adheres to the stirring rod 22 and the stirring blade 23 due to electrostatic effect. The motor 24 is started to drive the worm gear 25 to rotate, the worm gear 25 drives the worm wheel 26 to rotate, the worm wheel 26 drives the rotating rod 27 to rotate, and the rotating rod 27 drives the first striking plate 28 to rotate. The first striking plate 28 strikes the stirring blade 23 in rotation, causing the stirring blade 23 to vibrate. The stirring blade 23 also drives the stirring rod 22 to vibrate, and the toner powder adhering to the surface of the stirring rod 22 and the stirring blade 23 is shaken off, thus avoiding the toner powder on the stirring rod 22 from clumping and affecting the stirring.
[0028] like Figure 2 and Figure 5 As shown, the feeding assembly includes a powder feeding bin 41, which is fixedly connected to the toner cartridge body 1 and the mixing chamber 21. A feeding pipe 42 is fixedly connected to the middle of the top of the powder feeding bin 41, and the feeding pipe 42 is fixedly connected through the toner cartridge body 1. A discharge port 43 is opened on the bottom of the powder feeding bin 41 near the mixing chamber 21, and the discharge port 43 communicates with the mixing chamber 21. A lead screw 44 is rotatably connected to the middle of the powder feeding bin 41. One end of the lead screw 44 passes through the powder feeding bin 41 and the toner cartridge body 1. A feeding plate 46 is threadedly connected to the end of the lead screw 44 inside the powder feeding bin 41. The feeding plate 46 is slidably connected to the powder feeding bin 41. A heating tube 45 is rotatably connected inside the lead screw 44. Springs 47 are fixedly connected at equal intervals on both sides of the top of the powder feeding bin 41. A second striking plate 48 is fixedly connected to the bottom of the springs 47, and the second striking plate 48 abuts against the feeding plate 46.
[0029] In this embodiment, the screw 44 rotates, driving the feeding plate 46 to move. While the feeding plate 46 moves the toner, it heats the toner in the toner filling chamber 41 through the heating tube 45 to prevent the toner box body 1 from getting damp. When the feeding plate 46 moves, it comes into contact with the second striking plate 48. The second striking plate 48 gradually tilts and eventually separates from the feeding plate 46. At the moment of separation, the second striking plate 48 swings laterally through the elasticity of the spring 47, thereby colliding with the feeding plate 46. Therefore, the feeding plate 46 is vibrated, causing the toner adhering to the feeding plate 46 to be shaken off.
[0030] like Figure 2 and Figure 6 As shown, the drying assembly includes a drying box 31, which is slidably connected inside the toner box body 1 at the top of the mixing chamber 21. The drying box 31 is slidably connected to the mounting groove 12. Ventilation holes 32 are equidistantly arranged on one side of the drying box 31. A second cover 33 is rotatably connected to the top of the drying box 31. A drying block 34 is snapped into the inside of the drying box 31.
[0031] In this embodiment, when the latch 111 is engaged, the first latch 11 is pulled by the force applied to the latch rod 112, and the latch rod 112 is pulled out from the toner cartridge body 1. At this time, the first latch 11 is opened. Then, the operator inserts the drying box 31 into the installation slot 12 and places it at the top of the mixing chamber 21. Therefore, the air inside the toner cartridge body 1 can be dried by the setting of the drying block 34. Then, the first latch 11 is engaged, and the latch rod 112 is engaged with the toner cartridge body 1. The first latch 11 covers the drying box 31, improving the stability of the drying box 31. Therefore, it avoids the drying component being able to dry only the toner and not the rest of the space inside the toner.
[0032] Working principle: First, the operator engages the latch 111, causing the first cover 11 to pull the lever 112, which then pulls the lever 112 out of the toner cartridge body 1. At this point, the first cover 11 opens. Next, the operator inserts the drying box 31 into the mounting slot 12, positioned at the top of the mixing chamber 21. Therefore, the drying block 34 dries the air inside the toner cartridge body 1. Then, the first cover 11 is engaged, and the lever 112 engages with the toner cartridge body 1. The first cover 11 shields the drying box 31, improving its stability and preventing the drying component from only drying the toner and not the rest of the space inside. As the screw 44 rotates, it moves the feeding plate 46. While the feeding plate 46 moves the toner, it heats the toner in the powder filling chamber 41 via the heating tube 45, preventing moisture inside the toner cartridge body 1. The feeding plate 46 abuts against the second striking plate 48 as it moves. The second striking plate 48 gradually tilts and eventually separates from the material-dispensing plate 46. At the moment of separation, the second striking plate 48 swings laterally due to the elasticity of the spring 47, thus colliding with the material-dispensing plate 46. As a result, the material-dispensing plate 46 is vibrated, causing the toner adhering to it to be shaken off. Subsequently, the rotation of the stirring rod 22 drives the stirring blade 23 to rotate, and the stirring blade 23 stirs the incoming toner. Some toner adheres to the stirring rod 22 and the stirring blade 23 due to static electricity. The starting motor 24 drives the worm gear 25 to rotate, the worm gear 25 drives the worm wheel 26 to rotate, the worm wheel 26 drives the rotating rod 27 to rotate, and the rotating rod 27 drives the first striking plate 28 to rotate. The first striking plate 28 rotates and strikes the stirring blade 23, causing the stirring blade 23 to vibrate. The stirring blade 23 also drives the stirring rod 22 to vibrate, and the toner adhering to the surface of the stirring rod 22 and the stirring blade 23 is shaken off, thus preventing the toner on the stirring rod 22 from clumping and affecting the stirring.
[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
