[0024] like Figures 1 to 4 As shown, the present invention relates to a laser printer toner cartridge for preventing toner from being affected by moisture, comprising a toner cartridge shell 1 and a powder outlet 2 arranged at the bottom thereof, the outer wall of the toner cartridge shell 1 is fixedly connected to a motor 3, the outer wall of the toner cartridge shell 1 is fixedly connected to a guide rail 4, the inner wall of the guide rail 4 is provided with a guide groove 5, a flexible guide rod 6 is arranged in the guide groove 5, the outer wall of the toner cartridge shell 1 is fixedly connected to a storage cover 7, the inner wall of the storage cover 7 is hinged with a winding roller 8 through a torsion spring, one end of the flexible guide rod 6 passes through the guide groove 5 to the storage cover 7 and is fixedly connected to the outer wall of the winding roller 8, a sealing film 9 is fixedly connected to the opposite side between the flexible guide rods 6, the outer wall of the main shaft of the motor 3 is fixedly connected to a first ratchet 10, the rotating shaft of the winding roller 8 passes through the storage cover 7 to the outside thereof and is fixedly connected to a first sprocket 11, and the first sprocket 11 and the first ratchet 10 rotate synchronously through a chain.

[0025] When in use, toner is discharged from the powder outlet 2 to ensure the normal operation of the printer. When the printer is no longer printing, the staff controls the motor 3 to rotate forward, so that the motor 3 drives the first ratchet 10 to rotate, so that the first ratchet 10 drives the first sprocket 11 to rotate through the chain, and the rotation of the first sprocket 11 drives the winding roller 8 to rotate. The rotation of the winding roller 8 starts to release the flexible guide rod 6, so that the flexible guide rod 6 starts to drive the sealing film 9 to move in the guide rail 4. As the motor 3 continues to rotate, the flexible guide rod 6 drives the sealing film 9 to cover the powder outlet 2 at the bottom of the toner cartridge shell 1, thereby sealing the powder outlet 2 to prevent external water vapor from entering the interior of the toner cartridge shell 1, thereby causing the toner inside the toner cartridge shell 1 to be damp.

[0026] When the printer needs to print again, similarly, the staff controls the motor 3 to reverse, and the motor 3 has driven the winding roller 8 to rotate and release the flexible guide rod 6 when it rotates forward. Therefore, although the first motor 3 cannot drive the winding roller 8 to reverse through the first ratchet 10 at this time, the winding roller 8 will start to reverse under the torsion of its own torsion spring, so that the winding roller 8 can wind up the flexible guide rod 6 and the sealing film 9, so that the sealing film 9 no longer covers and seals the powder outlet 2 at the bottom of the toner cartridge shell 1, thereby ensuring that the toner is discharged from the powder outlet 2 normally.

[0027] As a preferred solution, Figures 2 to 5 As shown, the inner wall of the cartridge shell 1 is rotatably connected to a symmetrically arranged transmission roller 12, the outer wall of the rotating roller is sleeved with a conveyor belt 13, the outer wall of the conveyor belt 13 is fixedly connected to a plurality of flaps 14, the rotating shaft of the transmission roller 12 passes through the inner wall of the cartridge shell 1 to the outside thereof and is fixedly connected to a second sprocket 15, the outer wall of the main shaft of the motor 3 is fixedly connected to a second ratchet 16, the second ratchet 16 and the second sprocket 15 rotate synchronously through a chain, the transmission directions of the first ratchet 10 and the second ratchet 16 are oppositely arranged, a sieve plate 17 is arranged inside the cartridge shell 1, the interior of the sieve plate 17 is a hollow structure and is provided with an electric heating wire 18;

[0028] When in use, when the motor 3 is reversed, the motor 3 will not drive the winding roller 8 to rotate through the first ratchet 10, but the motor 3 will drive the second ratchet 16 to rotate, so that the second ratchet 16 drives the second sprocket 15 to rotate through the chain, so that the second sprocket 15 starts to drive the transmission roller 12 to rotate, and the rotation of the transmission roller 12 starts to drive the conveyor belt 13 to rotate in a circular manner, and the circular rotation of the conveyor belt 13 starts to drive the flap 14 to rotate, so that the flap 14 turns over the carbon powder accumulated inside the toner cartridge shell 1 during the rotation process, and turns it over from bottom to top, so that the carbon powder then falls from the conveyor belt 13 onto the sieve plate 17, and the electric heating wire 18 arranged inside the sieve plate 17 can heat the carbon powder after it falls on the sieve plate 17 to dry the carbon powder, and the dried carbon powder will fall from the mesh of the sieve plate 17, so as to circulate and realize the drying treatment of the carbon powder inside the toner cartridge shell 1.

[0029] It should be noted here that the reason why the reverse rotation of motor 3 does not drive the winding roller 8 to rotate, and the forward rotation of motor 3 does not drive the transmission roller 12 to rotate is, firstly, to prevent the motor 3 from being overloaded and causing insufficient power, and secondly, using one power source can reduce production costs.

[0030] As another preferred solution, Figure 3 and Figure 4 As shown, the outer wall of the cartridge housing 1 is provided with a film changing slot 19, the inner wall of the film changing slot 19 is provided with an insertion rod 20, and a drying sheet 21 is detachably connected to one side of the insertion rod 20 close to the inside of the cartridge housing 1;

[0031] When in use, the moisture inside the toner cartridge shell 1 is absorbed by the drying sheet 21, and the drying sheet 21 also absorbs the moisture generated when the toner is heated and dried, thereby increasing the drying effect and preservation effect of the toner inside the toner cartridge shell 1, and the drying sheet 21 can be replaced by plugging and pulling out the plug rod 20 in the sheet changing slot 19, thereby ensuring the continuous drying effect of the toner inside the toner cartridge shell 1.

[0032] As another preferred solution, Figure 3 and Figure 4 As shown, the sieve plate 17 is hinged to the inner wall of the cartridge housing 1 through a torsion spring, and when the flap 14 moves with the conveyor belt 13, the end of the flap 14 away from the conveyor belt 13 can move the sieve plate 17;

[0033] When in use, when the flap 14 and the conveyor belt 13 continue to flip the carbon powder onto the sieve plate 17, the section of the flap 14 away from the conveyor belt 13 will push the burning plate, so that the sieve plate 17 will start to shake under the torsion of its own torsion spring after being pushed, so that the shaking of the sieve plate 17 shakes the carbon powder. On the one hand, it can shake the carbon powder to prevent the carbon powder from clumping, and on the other hand, it can make the carbon powder pass through the sieve plate 17 evenly, thereby increasing the drying effect of the carbon powder.

[0034] As another preferred solution, Figure 4 As shown, an anti-stuck plate 22 is sleeved between the ends of the driving roller 12;

[0035] When in use, the anti-stuck plate 22 is provided to prevent carbon powder from entering between the conveyor belt 13 and the driving roller 12, thereby preventing the carbon powder from affecting the circular rotation of the conveyor belt 13 driven by the driving roller 12.

[0036] As another preferred solution, Figure 5 As shown, a receiving groove 23 is provided on the top of the sieve plate 17;

[0037] When in use, the receiving groove 23 can prevent the toner from sliding off the edge of the sieve plate 17 when the sieve plate 17 shakes the toner, thereby reducing the uniformity of the sieve plate 17 heating and drying the toner.

[0038] As another preferred solution, Figure 4 As shown, an integrated small temperature and humidity sensor 24 is fixedly connected to the inner wall of the cartridge housing 1;

[0039] When in use, the humidity inside the toner cartridge housing 1 can be monitored by the integrated small temperature and humidity sensor 24 .

[0040] As another preferred solution, Figure 3 As shown, the inner wall of the cartridge housing 1 is coated with a waterproof coating;

[0041] When in use, by coating the inner wall of the toner cartridge shell 1 with a waterproof coating, the moisture-proof effect of the toner cartridge shell 1 on carbon powder can be increased.

[0042] Working principle: This embodiment provides a laser printer toner cartridge that prevents toner from getting damp. When in use, toner is discharged from the powder outlet 2 to ensure the normal operation of the printer. When the printer is no longer printing, the staff controls the motor 3 to rotate forward, so that the motor 3 drives the first ratchet 10 to rotate, so that the first ratchet 10 drives the first sprocket 11 to rotate through the chain, and the rotation of the first sprocket 11 drives the winding roller 8 to rotate. The rotation of the winding roller 8 starts to release the flexible guide rod 6, so that the flexible guide rod 6 starts to drive the sealing film 9 to move in the guide rail 4. As the motor 3 continues to rotate, the flexible guide rod 6 drives the sealing film 9 to cover the powder outlet 2 at the bottom of the toner cartridge shell 1, thereby sealing the powder outlet 2, thereby preventing external water vapor from entering the interior of the toner cartridge shell 1, thereby causing the toner inside the toner cartridge shell 1 to get damp.

[0043] When the printer needs to print again, similarly, the staff controls the motor 3 to reverse, and the motor 3 has driven the winding roller 8 to rotate and release the flexible guide rod 6 when it rotates forward. Therefore, although the first motor 3 cannot drive the winding roller 8 to reverse through the first ratchet 10 at this time, the winding roller 8 will start to reverse under the torsion of its own torsion spring, so that the winding roller 8 can wind up the flexible guide rod 6 and the sealing film 9, so that the sealing film 9 no longer covers and seals the powder outlet 2 at the bottom of the toner cartridge shell 1, thereby ensuring that the toner is discharged from the powder outlet 2 normally.

[0044] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
