Description

Technical Field

[0001] The utility model relates to the technical field of electronic imaging devices, in particular to a toner filling device. Background Art

[0002] After the printing materials in electronic imaging devices such as laser printers and copiers are used up, the toner cartridges (such as toner cartridges with developing rollers and other components, developing cartridges, etc.) need to be directly replaced. In this way, the old toner cartridges will be directly scrapped and cannot be used again, resulting in waste of resources.

[0003] As Figure 1 and Figure 2 shown, there is currently an external toner filling device 4 that can replenish toner (such as printing toner) for the toner cartridge (not shown in the figure) in the electronic imaging device 1 (laser printer). When the toner in the toner cartridge in the electronic imaging device 1 is used up, it can directly inject toner into the toner cartridge installed in the electronic imaging device 1 through the input port of the toner receiving component (not shown in the figure), thereby increasing the service life of the toner cartridge. Its specific usage method is to install the toner cartridge into the electronic imaging device 1. When the toner in the toner cartridge is consumed to the low toner dose, the electronic imaging device 1 prompts to add toner. At this time, the user can add toner through the toner filling device 4, and the toner enters the toner storage bin of the toner cartridge from the toner receiving component.

[0004] The existing toner filling device uses a sponge for sealing, and there is a risk of toner leakage due to seal failure during storage and transportation. Summary of the Utility Model

[0048] Embodiment 1

[0049] This embodiment discloses a toner filling device 100 for adding toner to a toner cartridge. The toner cartridge (not shown) is installed in an electrophotographic apparatus. The toner cartridge includes a developing chamber, a powder chamber, a photosensitive chamber, and a toner receiving component 606. The developing chamber is provided with a developing roller, and the photosensitive chamber is provided with a photosensitive drum in contact with the developing roller; the powder chamber is used to accommodate toner, and the powder chamber is communicated with the developing chamber to be able to supply toner to the developing chamber. The toner receiving component 606 is communicated with the powder chamber, and the toner filling device 100 cooperates with the toner receiving component 606, so that the toner in the toner filling device 100 is added to the powder chamber through the toner receiving component 606.

[0050] As Figure 3 and Figure 4As shown, the toner receiving assembly 606 includes a base 607, a rotating member 609, and a driving member 608. An input port (not shown), an output port (not shown), and a channel 607a connecting the input port and the output port are provided on the base 607. The input port is formed on the inner sidewall of the base 607, and the output port communicates with the powder bin of the toner cartridge. The rotating member 609 is disposed within the base 607. The outer circumferential surface of the rotating member 609 is disposed in contact with the inner sidewall of the base 607, and the rotating member 609 is capable of rotating relative to the base 607. A first rib 609b and a mating protrusion 609e are formed on the inner wall of the rotating member 609. The first rib 609b and the mating protrusion 609e extend along the axial direction of the toner receiving assembly 606, and the first rib 609b and the mating protrusion 609e are disposed opposite to each other. An opening 609a is provided on the rotating member 609. When the rotating member 609 rotates to a position where the opening 609a coincides or partially coincides with the input port on the base 607, the toner in the toner filling device 100 can enter the toner cartridge through the toner receiving assembly 606. In the unfilled state, the opening 609a is located at a position that does not coincide with the input port; in the filled state, the opening 609a is located at a position that coincides with the input port. The driving member 608 is disposed on the top of the base 607 and is capable of rotating relative to the base 607. A handle 608b for easy gripping is provided on the driving member 608. The toner receiving assembly 606 further includes a second rib 610. The second rib 610 is stationary relative to the base 607. In the unfilled state, the second rib 610 is located inside the first rib 609b (the inside is the side closer to the central axis of the toner filling assembly 606). The toner receiving assembly 606 further includes a sealing sponge 611. The sealing sponge 611 is disposed inside the first rib 609b. In the unfilled state, the sealing sponge 611 is located between the first rib 609b and the second rib 610. The sealing sponge 611 is fixedly connected to the first rib 609b and can rotate with the rotating member 609 for sealing between the toner filling device 100 and the toner receiving assembly 606 in the filled state; an opening is also provided at the position of the sealing sponge 611 corresponding to the opening 609a so that the toner can pass through the opening of the sealing sponge 611 and enter the opening 609a during filling.

[0051] As Figure 5 and Figure 6 shown, the toner filling device 100 includes a storage body 11, a container base 12, a container valve 13, a seal, and a protective cover 14.

[0052] As Figure 5 and Figure 6As shown, a storage body 11 is used to store toner. It has a space inside for accommodating the toner, and the toner can be toner powder. The storage body 11 can be a bottle or a bag, etc., which is a flexible container convenient for pressing. The toner inside the storage body 11 can be discharged by extrusion. The lower end of the storage body 11 in the longitudinal direction (length direction) has an outlet.

[0053] As Figures 5 to 7 shown, a container base 12 is generally a columnar member, connected to the outlet position of the storage body 11. The container base 12 is provided with a powder outlet 121 communicating with the storage body 11. The powder outlet 121 is opened on the side wall of the container base 12. Inside the container base 12, there is a powder outlet passage extending from the upper end of its longitudinal direction to the powder outlet 121, that is, the powder outlet passage extends longitudinally.

[0054] As Figure 6 shown, the container base 12 and the storage body 11 can be connected by threads. Specifically, the upper end of the container base 12 in the longitudinal direction is provided with a connecting portion 122, and the inner wall of the connecting portion 122 is provided with threads. The lower end of the storage body 11 is also provided with matching threads.

[0055] As Figure 6 and Figure 7 shown, the container base 12 is also provided with a coupling portion 123. The coupling portion 123 is a flange formed on the outer circumferential surface of the container base 12. The coupling portion 123 is located below the connecting portion 122 in the longitudinal direction.

[0056] As Figure 9 and Figure 10 shown, a container valve 13 is generally a columnar member. The container valve 13 is rotatably sleeved on the outside of the container base 12. The upper end of the container valve 13 in the longitudinal direction is provided with a engaging portion, which is combined with the coupling portion 123 on the container base 12, so as to rotatably mount the container valve 13 on the outside of the container base 12 and prevent the container valve 13 from disengaging in the longitudinal direction. The engaging portion includes a first protrusion 131 and a third protrusion 138. There can be multiple first protrusions 131, which are distributed on the upper end of the inner side wall of the container valve 13. During assembly, the first protrusion 131 is stuck on the upper side of the coupling portion 123 (flange) of the container base 12.

[0057] Furthermore, the third protrusion 138 is arranged below one of the first protrusions 131 and is spaced from the first protrusion 131, forming a track 139 therebetween. During assembly, the coupling portion 123 is snapped into the track 139, so as to mount the container valve 13 on the outside of the container base 12, making the container valve 13 rotatable relative to the container base 12 while not easily disengaging.

[0058] Furthermore, as Figure 9 and Figure 10As shown, the container valve 13 is further provided with a structure cooperating with the toner receiving component 606. Specifically, a first groove 133 is formed on the side wall of the container valve 13, and the first groove 133 extends longitudinally along the container valve 13. When the toner filling device 100 is inserted into the toner receiving component 606, the first groove 133 engages with a first convex rib 609b provided on the inner wall of the rotating member 609, and two groove walls 133a, 133b of the first groove 133 are attached to two end faces in the circumferential direction of the first convex rib 609b, so that the container valve 13 and the rotating member 609 are relatively stationary.

[0059] Furthermore, as Figure 10 shown, a second groove 135 is further formed on the outer circumferential surface of the container valve 13, and the second groove 135 extends longitudinally along the container valve 13. When the toner filling device 100 is inserted into the toner receiving component 606, the second groove 135 engages with a mating protrusion 609e, that is, two groove walls 135a, 135b of the second groove 135 are attached to two end faces in the circumferential direction of the mating protrusion 609e, thereby making the container valve 13 and the rotating member 609 relatively stationary.

[0060] Furthermore, as Figure 9 and Figure 10 shown, the container valve 13 is further provided with a notch portion 134 and a third convex rib 1310 that engage with the driving member 608. The notch portion 134 is provided at the edge of the upper end in the longitudinal direction of the container valve 13, and the notch portion 134 is a substantially semi-circular notch; the third convex rib 1310 is provided on the outer circumferential surface of the container valve 13 and extends longitudinally. After the notch portion 134 and the third convex rib 1310 engage with the driving member 608, the container valve 13 and the driving member 608 are relatively stationary. When the handle 608b on the driving member 608 is rotated to rotate the driving member 608, the container valve 13 is driven to rotate synchronously, and the rotating member 609 also rotates following the drive of the container valve 13. The container valve 13 can be driven to rotate in a first direction, and the first direction is the direction in which the container valve 13 drives the rotating member 609 to rotate so that the opening 609a coincides with the input port. The rotation angle of the driving member 608 is approximately 90°.

[0061] As Figures 5 to 7 shown, when the toner filling device 100 is inserted into the toner receiving component 606, the container base 12 does not rotate relative to the toner receiving component 606. Specifically, a protrusion 125 is provided at the lower end in the longitudinal direction of the container base 12, and the protrusion 125 is a special-shaped protrusion. A through hole is provided at the lower end of the container valve 13. When the container base 12 and the container valve 13 are combined, the protrusion 125 passes through the through hole and extends to the lower end of the container valve 13. The protrusion 125 can engage with the base 607 of the toner receiving component 606, so that the container base 12 cannot rotate relative to the toner receiving component 606.

[0062] Furthermore, as Figure 8 shown, a first groove 1210 is further provided on the outer circumferential surface of the container base 12. The first groove 1210 extends along the axial direction of the toner filling device 100. When the toner filling device 100 is inserted into the toner receiving component 606, the first groove 1210 engages with the second rib 610. The two groove walls 1210a and 1210b of the first groove 1210 are in contact with the two end faces of the second rib 610 in the circumferential direction. Since the second rib 610 is relatively stationary with respect to the base 607, after the container base 12 is engaged with it, the container base 12 can be further limited in position and cannot rotate. The first groove 1210 is located beside the powder outlet 121 in the circumferential direction of the container base 12 (i.e., they do not overlap radially).

[0063] As Figure 6 shown, the protective cover 14 covers the outside of the container base 12 and the container valve 13 to play a protective role.

[0064] In this embodiment, as Figure 5 and Figure 6 shown, the seal covers the powder outlet 121 to form a seal for the powder outlet 121. Preferably, the seal is a seal strip 15. The seal strip 15 at least partially adheres to the outer circumferential surface of the container base 12 and completely covers the powder outlet 121. The upper end of the seal strip 15 also has a pulling section 151. The pulling section 151 does not adhere to the container base 12 and can be folded away from the container base 12, facilitating the user to pull the seal strip 15 by applying force after holding the pulling section 151. That is, the seal is removed relative to the container base 12 or the container valve 13 to open the powder outlet 121.

[0065] As Figure 5 and Figure 6 shown, the part of the seal covering the powder outlet 121 is exposed from the container valve 13. Specifically, the part of the seal strip 15 covering the powder outlet 121 is not covered by the container valve 13 (there is no overlapping part radially). That is, the powder outlet 121 and the part of the seal strip 15 covering the powder outlet 121 are both within the range of the first groove 133 of the container valve 13, and at least part of the seal strip 15 is exposed through the first groove 133.

[0066] In this embodiment, as Figures 3 to 11As shown, the container valve 13 can rotate relative to the seal (seal strip 15), and the removal of the seal strip 15 has no relation to the movement of the container valve 13. The new toner filling device 100 is inserted into the toner receiving component 606 from top to bottom (inserted along the D1 direction). At this time, the opening 609a of the rotating member 609 is located at a position offset from the input port of the base 607. The first groove 133 of the container valve 13 engages with the first rib 609b, the second groove 135 engages with the mating projection 609e, the notch 134 and the third rib 1310 engage with the driving member 608, the protruding portion 125 engages with the base 607, the first groove 1210 engages with the second rib 610, and the position of the powder outlet 121 of the container base 12 is opposite to the input port. However, since the opening 609a of the rotating member 609 is offset from the input port and the seal (seal strip 15) remains in a sealed state, the toner in the toner filling device 100 cannot enter the toner receiving component 606 yet. The user holds the handle 608b of the driving member 608 and rotates it counterclockwise (the first direction) by 90°. The driving member 608 drives the container valve 13 to rotate relative to the container base 12, and the container valve 13 drives the rotating member 609 to rotate relative to the base 607, so that the opening 609a coincides and communicates with the input port. Then, hold the pulling section 151 of the seal strip 15 (seal) and pull out the seal strip 15 forcefully (as Figure 11 shown), so that the powder outlet 121 communicates with the opening 609a and the input port. Then, squeeze the storage body 11 so that the toner is discharged from the powder outlet 121 into the toner receiving component 606 and finally enters the powder bin of the toner cartridge.

[0067] In this embodiment, the rotational movement of the container valve 13 is only used to make the opening 609a of the rotating member 609 coincide with the input port of the base 607. After the opening 609a coincides with the input port, the seal strip 15 needs to be manually pulled out to communicate the powder outlet 121 and the input port. The sealing performance is good, and there is no risk of toner leakage due to failure.

[0068] Embodiment 2

[0069] This embodiment provides another toner filling device 100. Compared with Embodiment 1, the difference lies in that the container base 12 and the container valve 13 are integrally provided.

[0070] As Figures 12 to 14As shown, the container valve 13 and the container base 12 are of an integrated structure, and the container valve 13 and the container base 12 cannot rotate relative to each other. The container valve 13 and the container base 12 are collectively referred to as the powder outlet part 12a. When the powder outlet part 12a is inserted into the toner filling device 100, it still needs to rotate to drive the rotating part 609 so that its opening 609a is aligned with the input port of the base 607. Since the entire powder outlet part 12a is integrally arranged, when it is driven by the driving part 608 to rotate, the powder outlet part 12a rotates together. Therefore, the position of the powder outlet 121 needs to be set offset from the position of the input port. That is, another difference between this embodiment and the first embodiment is that when the toner filling device 100 is inserted into the toner receiving assembly 606, the position of the powder outlet 121 does not correspond to the position of the input port, but is provided on the side wall of the container base 12 that is deflected 90° relative to the input port. As Figures 12 to 14 shown, the powder outlet 121 is arranged in the first groove 1210 of the container base 12, and the two have an overlapping part in the radial direction. The seal (seal strip 15) also correspondingly fits in the first groove 1210 of the container base 12 to cover the powder outlet 121. The first groove 1210 and the powder outlet 121 are not covered by the container valve 13, so the part of the seal strip 15 covering the powder outlet 121 is not covered by the container valve 13 either, that is, the seal (seal strip 15) is exposed from the container valve 13.

[0071] The storage body 11 is fixedly connected to the container base 12, so when the container base 12 rotates, the storage body 11 also rotates together. That is, when the driving part 608 drives the powder outlet part 12a to rotate, the container base 12, the container valve 13, the storage body 11, and the seal are relatively stationary.

[0072] As Figure 13 and Figure 14 shown, another difference between this embodiment and the first embodiment is that the protruding part 125 is arranged to be rotatable relative to the powder outlet part 12a. Specifically, an installation part for the protruding part 125 is provided at the bottom (lower end) of the powder outlet part 12a, and the installation part can be specifically opened at the bottom of the container base 12 / container valve 13. The installation part is in the shape of a cylindrical groove, and a first annular groove 127 and a second annular groove 128 are provided on the inner side wall of the installation part. The radius of the second annular groove 128 is greater than the radius of the first annular groove 127, the circumference of the first annular groove 127 is greater than the circumference of the second annular groove 128, and the first annular groove 127 and the second annular groove 128 are connected and merged into a complete circle in the circumferential direction.

[0073] As Figures 13 to 16As shown, the protrusion 125 includes an annular portion 1251 and a special-shaped block 1252 provided at the lower end of the annular portion 1251. Ribs 1253 are circumferentially arranged on the outer surface of the annular portion 1251. The ribs 1253 have a notch section (i.e., the ribs 1253 are not a complete circle), and a protrusion 1254 is provided at one end of the ribs 1253 along its circumference. The outer surface of the annular portion 1251 is adapted to the inner side wall of the mounting portion. The first annular groove 127 is adapted to the ribs 1253, and the second annular groove 128 is adapted to the protrusion 1254. During assembly, the ribs 1253 are embedded in the first annular groove 127 and can rotate along the first annular groove 127, installing the protrusion 125 in the mounting portion so that the protrusion 125 can rotate relative to the powder outlet portion 12a without coming off. The protrusion 1254 is located in the second annular groove 128 and can rotate along the second annular groove 128. The protrusion 1254 can limit the rotation angle of the protrusion 125. After the protrusion 1254 rotates to the end of the first annular groove 127, it will abut against the end of the second annular groove 128 and cannot rotate further (the radius of the second annular groove 128 is greater than that of the first annular groove 127, and the protrusion 1254 cannot rotate to the position of the first annular groove 127), that is, the movement of the powder outlet portion 12a relative to the protrusion 125 stops, thereby limiting the rotation angle of the protrusion 125 within the circumference range of the second annular groove 128. In the filling state, the protrusion 125 is engaged with the base 607 and does not move, and it is the powder outlet portion 12a that rotates relative to the base 607. Therefore, the cooperation between the protrusion 1254 and the second annular groove 128 limits the rotation angle of the powder outlet portion 12a.

[0074] As Figure 3 , Figure 4 , Figures 12 to 16As shown, the new toner filling device 100 is inserted into the toner receiving component 606 from top to bottom (inserted along the D1 direction). At this time, the opening 609a of the rotating member 609 is located at a position offset from the input port of the base 607, the powder outlet 121 is located at a position deflected 90° relative to the input port, the first groove 133 of the container valve 13 engages with the first rib 609b, the second groove 135 engages with the mating protrusion 609e, the first groove 1210 engages with the second rib 610, the notch portion 134 and the third rib 1310 engage with the driving member 608, and the special-shaped block 1252 of the protruding portion 125 engages with the base 607. The user holds the handle 608b of the driving member 608 and rotates it counterclockwise by 90°. The driving member 608 drives the container valve 13 and the container base 12 to rotate together (the entire toner filling device 100 rotates). The container valve 13 drives the rotating member 609 to rotate relative to the base 607, so that the opening 609a coincides and communicates with the input port. During the overall rotation of the toner filling device 100, the powder outlet 121 rotates to a position aligned with the input port. At the same time, the powder outlet portion 12a also rotates relative to the protruding portion 125, that is, the rib 1253 rotates in the first annular groove 127, and the protrusion 1254 rotates in the second annular groove 128. After the protrusion 1254 abuts against the end of the first annular groove 127, the powder outlet portion 12a can no longer rotate (this position is the position where the opening 609a, the input port, and the powder outlet 121 are aligned and coincide). Then hold the pulling section 151 of the seal 15 and pull the seal 15 forcefully to make the powder outlet 121 communicate with the opening 609a and the input port. Then squeeze the storage body 11 so that the toner is discharged from the powder outlet 121 into the toner receiving component 606 and finally enters the powder bin of the toner cartridge.

[0075] The other structures of the toner filling device 100 are similar to those in the first embodiment and will not be described in detail here.

[0076] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
