[0001] The utility model relates to the technical field of selenium cartridges, in particular to a toner powder replenishing device for selenium cartridges. Background Art

[0002] Toner cartridge, also known as photosensitive drum, is one of the core components of laser printers and copiers. Its main function is to adhere toner to paper through processes such as laser exposure and electrostatic imaging, thereby completing printing or copying.

[0003] A Chinese patent discloses a toner cartridge structure (authorization announcement number CN219676447U). The patented technology uses a limit ring to limit the position of the first gear and the second gear. The limit ring replaces the retaining ring, which can avoid the assembly of the retaining ring. It not only reduces the number of parts, but also eliminates the problem of the retaining ring being difficult to install, and can effectively improve the production and assembly efficiency.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: in the process of replenishing existing toner, the toner cartridge is turned upside down and directly replenished into the interior of the toner cartridge. Since the toner particles are fluid, when the toner cartridge is turned upside down, the toner will flow out quickly, and it is often difficult for users to accurately control the speed and amount of the outflow, which causes the toner to easily spill onto the outside of the toner cartridge, which not only causes a waste of toner, but also causes potential harm to the environment and the health of users. Utility Model Content

For this reason, we propose a toner cartridge toner replenishing device.

[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a toner cartridge and toner powder replenishing device, comprising a toner cartridge box and a toner powder cartridge, the toner cartridge box having a powder filling hole at the top, a powder outlet head fixedly connected to the bottom of the toner powder cartridge, a sealing valve installed inside the powder outlet head, a through hole at the top of the sealing valve, an insertion hole at one end of the powder outlet head, a connecting rod fixedly connected to one end of the sealing valve, and the surface of the connecting rod is rotatably connected to the inside of the insertion hole.

[0007] Preferably, the sealing valve is in the shape of a sphere, and the surface of the sealing valve fits with the inner wall of the powder outlet head.

[0008] Preferably, a movable groove is provided at one end of the connecting rod, a movable rod is slidably connected inside the movable groove, a handle is fixedly connected to one end of the movable rod, a plug-in rod is fixedly connected to one end of the handle, and a plug-in groove is provided at one end of the powder outlet head.

[0009] Preferably, both sides of the inner cavity of the movable groove are provided with limiting grooves, and both sides of the movable rod are fixedly connected with limiting blocks.

[0010] Preferably, one end of the movable rod is fixedly connected to a first spring, and one end of the first spring is fixedly connected to the inside of the movable groove.

[0011] Preferably, the outer shape of the plug-in rod matches the inner shape of the plug-in slot.

[0012] Preferably, the sealing valve is made of stainless steel.

[0013] Technical effects and advantages of the utility model:

[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a toner cartridge carbon powder replenishing device, comprising a toner cartridge 1 and a toner cartridge 3, a powder filling hole 2 is provided on the top of the toner cartridge 1, a powder outlet head 4 is fixedly connected to the bottom of the toner cartridge 3, a sealing valve 5 is installed inside the powder outlet head 4, a through hole 6 is provided on the top of the sealing valve 5, an insertion hole 7 is provided at one end of the powder outlet head 4, a connecting rod 8 is fixedly connected to one end of the sealing valve 5, and the surface of the connecting rod 8 is rotatably connected to the inside of the insertion hole 7. The staff aligns the powder outlet head 4 with the powder filling hole 2 on the top of the toner cartridge 1 and puts the powder outlet head 4 into the powder filling hole 2, and then rotates the connecting rod 8 to drive the sealing valve 5 to rotate, so that the direction of the through hole 6 provided on the surface of the sealing valve 5 is perpendicular to the direction of the powder filling hole 2, so that when the staff replenishes the toner cartridge 1 with toner, there will be no leakage or improper inflow of toner.

[0023] Reference Figure 2 As shown, in this embodiment: the sealing valve 5 is in the shape of a sphere, and the surface of the sealing valve 5 fits with the inner wall of the powder outlet head 4. By setting the shape of the sealing valve 5 to a sphere, the sealing valve 5 can rotate smoothly inside the powder outlet head 4. The staff only needs to simply turn the connecting rod 8 to adjust the position of the sealing valve 5. At the same time, it can prevent toner from leaking out from the inside of the powder outlet head 4, realize the opening or closing of the powder filling channel, and improve the versatility and flexibility of the equipment.

[0024] Reference Figure 4 and Figure 5 As shown, in the present embodiment: a movable groove 9 is provided at one end of the connecting rod 8, a movable rod 10 is slidably connected inside the movable groove 9, a handle 11 is fixedly connected to one end of the movable rod 10, a plug-in rod 13 is fixedly connected to one end of the handle 11, and a plug-in groove 12 is provided at one end of the powder outlet head 4. When the staff puts the sealing valve 5 in a closed state, the movable rod 10 is pushed to move the movable rod 10 inside the movable groove 9, thereby driving the plug-in rod 13 to move, so that the plug-in rod 13 is inserted into the plug-in groove 12 opened at one end of the powder outlet head 4 to fix the position of the sealing valve 5 and avoid shaking when not in use.

[0025] Reference Figure 4 As shown, in this embodiment: limiting grooves 14 are provided on both sides of the inner cavity of the movable groove 9, and limiting blocks 15 are fixedly connected on both sides of the movable rod 10. Through the mutual cooperation between the limiting grooves 14 and the limiting blocks 15, when the staff pulls the movable rod 10, the limiting blocks 15 can abut against the limiting grooves 14 to prevent the movable rod 10 from falling off from the inside of the movable groove 9.

[0026] Reference Figure 4As shown, in the present embodiment: one end of the movable rod 10 is fixedly connected to the first spring 16, and one end of the first spring 16 is fixedly connected to the inside of the movable groove 9. Through the setting of the first spring 16, when the staff pulls the movable rod 10 outward, the first spring 16 will start to accumulate force. When the staff releases the first movable rod 10, the first spring 16 will drive the movable rod 10 to rebound quickly through its own elastic force, so that the staff can fix the sealing valve 5 more quickly.

[0027] Reference Figure 4 and Figure 5 As shown, in this embodiment: the outer shape of the plug rod 13 is consistent with the inner shape of the plug slot 12. When the outer shape of the plug rod 13 is consistent with the inner shape of the plug slot 12, the noise and looseness caused by vibration or impact can be reduced, ensuring the stability and reliability between the connecting parts.

[0028] Reference Figure 2 As shown, in this embodiment: the sealing valve 5 is made of stainless steel, which is easy to clean, not easy to stick to materials, and not easy to rust.

[0029] Working principle: the staff aligns the powder outlet head 4 with the powder filling hole 2 on the top of the toner cartridge 1 and puts the powder outlet head 4 into the powder filling hole 2, and then rotates the connecting rod 8 to drive the sealing valve 5 to rotate, so that the direction of the through hole 6 opened on the surface of the sealing valve 5 is perpendicular to the direction of the powder filling hole 2, so that when the staff replenishes toner to the toner cartridge 1, there will be no leakage or improper inflow of toner powder, and the shape of the sealing valve 5 is set to a spherical shape so that the sealing valve 5 can rotate smoothly inside the powder outlet head 4. The staff only needs to simply rotate the connecting rod 8 to adjust the position of the sealing valve 5, and at the same time, it can prevent toner from leaking from the inside of the powder outlet head 4, so as to open or close the powder filling channel, thereby improving the versatility and flexibility of the equipment. When the staff closes the sealing valve 5, the movable rod 10 is pushed to move the movable rod 10 inside the movable groove 9, thereby driving the plug-in rod 13 to move, so that the plug-in rod 13 is inserted into the plug-in groove 12 opened at one end of the powder outlet head 4 to fix the position of the sealing valve 5 to avoid shaking when not in use. Through the mutual cooperation of the limit groove 14 and the limit block 15, when the staff pulls the movable rod 10, the limit block 15 can abut against the limit groove 14 to prevent the movable rod 10 from falling off from the inside of the movable groove 9. Through the setting of the first spring 16, when the staff pulls the movable rod 10 outward, the first spring 16 will start to accumulate force. When the staff releases the movable rod 10, the first spring 16 will drive the movable rod 10 to rebound quickly through its own elastic force, so that the staff can fix the sealing valve 5 more quickly. When the external shape of the plug-in rod 13 coincides with the internal shape of the plug-in groove 12, it can reduce noise and looseness caused by vibration or impact, and ensure the stability and reliability between the connecting parts. The stainless steel material is easy to clean, not easy to stick to materials, and not easy to rust.
