[Technical field]

[0002] The present application relates to the field of printing technology, and in particular to a power receiving component and a powder cartridge. [Background technology]

[0003] Toner cartridges are widely used in the field of electronic imaging. They are used in image forming devices and provide developer for image forming devices. Image forming devices are devices that form images on recording materials through electrophotographic imaging processing technology, such as: electrophotographic copiers, laser printers, electrophotographic printers, fax machines, word processors, etc.

[0004] The existing powder cartridge mainly includes a cartridge body and a power receiving component. A large amount of developer is contained in the cartridge body; the cartridge body is generally a columnar structure. A power receiving component is usually provided on the side wall at one end of the cartridge body in the length direction. The power receiving component is connected to the cartridge body. The power receiving component receives the rotational driving force from the image forming device, and then transmits the rotational driving force to other parts of the powder cartridge so that the powder cartridge can discharge the developer outward. Usually, the powder outlet of the powder cartridge for discharging the developer is located near or on the power receiving component.

[0005] The part of the existing image forming device connected to the powder cartridge is the rotating driving force transmission component of the image forming device. The rotating driving force transmission component is provided with a special structure, and a needle-shaped device is located in the center of the rotating driving force transmission component and is substantially flush with the opening of the rotating driving force transmission component. When the powder cartridge is mounted on the image forming device, the rotating driving force transmission component moves toward the powder cartridge, and the needle-shaped device of the rotating driving force transmission component correspondingly penetrates into the interior of the power receiving component. Afterwards, the pushing device surrounding the inner wall of the rotating driving force transmission component is retracted in a direction away from the powder cartridge, and then the image forming device drags the powder cartridge to move in a direction away from the rotating driving force transmission component, opens the opening of the powder cartridge, and the developer can flow out; when the image forming device stops the imaging work and removes the powder cartridge from the image forming device, the image forming device drags the powder cartridge to move in the direction of the rotating driving force transmission component to close the opening on the powder cartridge, and the pushing device surrounding the inner wall of the rotating driving force transmission component pushes in the direction of the powder cartridge, and the rotating driving force transmission component moves in a direction away from the powder cartridge, and the powder cartridge can be taken out at this time. Due to the poor structural design, irregular use, unqualified production materials and other reasons of the existing powder cartridge, the rotary driving force transmission component cannot be fully engaged with the power receiving component or is easily disengaged after being engaged. [Summary of the invention]

[0006] The present application provides a power receiving component and a powder cartridge, which can prevent the developer stored in the powder cartridge from leaking during transportation and movement, thereby polluting the environment.

[0012] The movable part can move relative to the support rod, and during the movement of the movable part relative to the support rod, there is at least one position where the receiving part cannot be disengaged from the electronic imaging device due to the interaction between the support rod and the movable part.

[0013] Optionally, during the movement of the movable portion relative to the support rod, there is at least one position where the support rod cannot be deflected radially inward along the rotation axis of the powder cartridge body under the action of the movable portion.

[0014] Optionally, a first elastic member is provided between the movable part and the receiving part; the movable part includes an abutting part and a pushing part; the electronic imaging device abuts against the abutting part and pushes the movable part to move along the rotation axis direction of the powder cartridge body; the pushing part abuts against the support rod.

[0015] Optionally, an anti-slip groove is provided on the support rod, and the forced pushing portion is located inside the anti-slip groove. The anti-slip groove can prevent the movable portion from slipping out of the power receiving component when the movable portion moves relative to the support rod.

[0016] Optionally, the transmission rod is rigidly connected to the support rod; the power receiving component includes a transmission part, which is connected to the powder cartridge body and abuts against the transmission rod, so that the transmission rod can transmit the power from the electronic imaging device received by the receiving tooth to the powder cartridge body.

When the powder cartridge is working in the image forming device, the rotational driving force transmission component is engaged with the power receiving component and the developer in the powder cartridge can enter the image forming device from the powder cartridge; when the powder cartridge is removed from the image forming device, the developer in the powder cartridge no longer enters the outside world from the powder cartridge, which can prevent the developer stored in the powder cartridge from leaking during transportation and movement, thereby polluting the environment.

[0033] Embodiment 1

[0034] This embodiment provides a power receiving component, such as Figure 1 , Figure 2 As shown, it includes a movable part 110, a receiving part 120, a transmission part 130, and a first elastic member 150. Preferably, an elastic gasket 140 is also provided.

[0035] like Figure 3 As shown, the transmission part 130 is provided with a convex eave 131 and a protruding block 132. The transmission part 130 is connected to the powder cartridge body, and the inner wall of the powder cartridge body can abut against the outer wall of the transmission part 130 or the outer wall of the powder cartridge body can abut against the inner wall of the transmission part 130. The connection method includes but is not limited to the existing technologies in the mechanical industry such as thermoforming, gluing, and riveting, which will not be repeated here.

[0036] The receiving part 120 is provided with a receiving tooth 123, a supporting rod 124, a transmission rod 125, an anti-slip groove 126, a first locking tooth 122 and a second locking tooth 121. The receiving tooth 123 can receive the rotational driving force from the image forming device; the supporting rod 124 is elastic and can be radially deflected inward along the rotation axis of the powder cartridge body; the transmission rod 125 can abut against the protruding block 132, so that the rotational driving force is transmitted from the receiving part 120 to the transmission part 130, and then to the powder cartridge body; the first locking tooth 122 and the second locking tooth 121 are used to prevent the receiving part 120 from slipping off the transmission part 130. When the powder cartridge works normally in the image forming device, the first locking tooth 122 just abuts against the convex eave 131, or the first locking tooth 122 has not yet abutted against the convex eave 131. The second locking tooth 121 is a backup measure, which is used as a safety measure when the first locking tooth 122 breaks or the receiving part 120 is pulled out of the position where the first locking tooth 122 abuts against the convex eaves. At this time, the second locking tooth 121 abuts against the convex eaves to prevent the receiving part 120 from being pulled out of the transmission part 130 as a whole. Preferably, in order to ensure that the receiving part 120 and the transmission part 130 are separated smoothly, the first locking tooth 122 and the second locking tooth 121 will not interfere with other parts of the transmission part 130. Once a failure such as preventing the receiving part 120 from being pulled out of the transmission part 130 as a whole occurs inside the image forming device, it will not only affect the quality of this printing, but also damage the inside of the image forming device. At the same time, if the damaged toner cartridge is not properly handled, it will also affect the health of the user and even pollute the air and water sources.

[0037] The movable part 110 is provided with an abutment part 111 and a forced pushing part 112. The abutment part 111 can abut against the image forming device to move the movable part 110 in the direction of the rotating axis of the powder cartridge body. The height of the radial protrusion of the abutment part 111 in the rotating axis of the powder cartridge body is greater than the height of the radial protrusion of the receiving tooth 123 in the rotating axis of the powder cartridge body. The forced pushing part 112 can enter the anti-slip groove 126. When the forced pushing part 112 is in the anti-slip groove 126, the support rod 124 cannot be deflected radially inward along the rotating axis of the powder cartridge body due to the existence of the movable part 110.

[0038] A first elastic member 150 is further provided between the movable portion 110 and the receiving portion 120 . Preferably, the first elastic member 150 is a spring. The movable position of the movable portion 110 is limited by the receiving portion 120 .

[0039] The process of loading the toner cartridge into the image forming device is described in detail below. The movable component 998 on the image forming device is located inside the rotation driving force transmission component 999.

[0040] The first step, such as Figure 4As shown, when the powder cartridge is not loaded into the image forming device, the forced pushing portion 112 of the power receiving component is in the anti-slip groove 126, and the support rod 124 cannot deviate radially inward along the rotation axis of the powder cartridge body. The receiving portion 120 and the transmission portion 130 are tightly attached to each other, so that the developer stored in the powder cartridge body cannot flow out. Preferably, an elastic gasket 140 is also provided between the receiving portion 120 and the transmission portion 130 to improve the sealing performance.

[0041] In the second step, after the powder cartridge is loaded into the image forming device, since the radial distance between the abutment portion 111 and the rotation axis of the powder cartridge body is greater than the radial distance between the receiving tooth 123 and the rotation axis of the powder cartridge body, the movable component 998 on the image forming device pushes the abutment portion 111, causing the movable portion 110 to move toward the powder cartridge body, and the forced retreat portion 112 leaves the anti-slip groove 126. Figure 5 The support rod 124 can now be offset radially inwardly along the rotation axis of the powder cartridge body.

[0042] In the third step, the rotational driving force transmission component 999 on the image forming device moves toward the powder cartridge body. Due to the interference between the rotational driving force transmission component 999 and the driving teeth 123, the support rod deviates radially inward along the rotation axis of the powder cartridge body, and the receiving portion 120 meshes with the rotational driving force transmission component 999. Figure 6 shown.

[0043] In the fourth step, the movable component 998 on the image forming device moves away from the powder cartridge body. Due to the presence of the first elastic member 150, the movable portion 110 follows the movable component 998 and moves away from the powder cartridge body until the forced pushing portion 112 enters the anti-slip groove 126. Figure 7 At this time, the support rod 124 cannot deviate radially inward along the rotation axis of the powder cartridge body because it is pressed by the abutment portion 112 .

[0044] In the fifth step, the image forming device drags the transmission part 130 or the powder cartridge body to move in a direction away from the rotational driving force transmission component 999 (the same direction as the powder cartridge body in the third step). Since the support rod 124 cannot be radially deflected inward along the rotation axis of the powder cartridge body, the receiving part 120 cannot be disengaged from the rotational driving force transmission component 999, and a gap will appear between the receiving part 120 and the transmission part 130, which allows the developer stored in the powder cartridge body to flow out. Figure 8 After that, the image forming device can transmit the rotational driving force to the receiving part 120 through the rotational driving force transmission component 999, and then transmit it to the transmission part 130 through the transmission rod 125 and the protruding block 132, and finally transmit it to the powder cartridge body, so that the developer stored in the powder cartridge body can flow out continuously.

[0045] When the toner cartridge is removed from the image forming device, Figure 8In the state of the image forming device, the transmission part 130 or the powder cartridge body is first pushed by the image forming device to close the gap between the receiving part 120 and the transmission part 130, and then the image forming device 130 is turned into a Figure 7 Then the movable member 998 moves toward the powder cartridge body and drives the movable portion 110 to move toward the powder cartridge body to become Figure 6 After that, the rotational driving force transmission member 999 moves in a direction away from the powder cartridge body, and becomes Figure 5 Next, the movable part 998 moves in a direction away from the powder cartridge body, and the movable part 110 moves with the movable part 998 until the forced pushing part 112 interferes with the anti-slip groove 126, preventing the movable part 110 from moving further away from the powder cartridge; finally, the user can pull out the powder cartridge, and the power receiving component can be restored to Figure 4 Status in.

[0046] Embodiment 2

[0047] The structure of the power receiving component involved in this embodiment is basically the same as that in the first embodiment. The difference is that the power receiving component in this embodiment further includes a second elastic member 160. At the same time, in order to accommodate the second elastic member 160, the shape of the receiving portion 120 is modified.

[0048] like Fig. 9 As shown, the second elastic member 160 is located on the receiving portion 120. Preferably, the second elastic member 160 is located on the receiving tooth 123. Of course, the second elastic member 160 can also be arranged at other positions of the receiving portion 120. A groove can be arranged on the receiving tooth 123, so that the second elastic member 160 can be accommodated in the groove. When the movable part 110 moves toward the direction of the powder cartridge barrel along the rotation axis direction of the powder cartridge barrel, the support rod 124 is radially offset inward relative to the rotation axis of the powder cartridge barrel under the action of the second elastic member 160. In this embodiment, the second elastic member 160 is a ring-mounted elastic member, which is coaxially arranged with the rotation axis of the power receiving component. Preferably, the second elastic member 160 is a rubber band.

[0049] Compared with the power receiving component involved in the first embodiment, the power receiving component involved in this embodiment has the second elastic member 160 radially constraining the receiving portion 120 inwardly due to the elastic force, thereby reducing the interference between the receiving teeth 123 and the image forming device during the installation and disassembly of the powder cartridge, thereby preventing the friction and collision between the receiving teeth 123 and the image forming device during the installation and disassembly of the powder cartridge.

[0050] Preferably, in order to prevent the second elastic member 160 from being aged and broken when it is a rubber product and falling into the image forming device to damage the quality of electronic imaging or the image forming device, the second elastic member can be connected to the receiving tooth 123 or the support rod 124. Adhesion, thermoforming or interference fit can be selected, which will not be described in detail here.

[0051] Embodiment 3

[0052] The structures of the power receiving components involved in this embodiment and the first embodiment are basically the same, and the difference is that the movable parts 110a and 110b in this embodiment are different in structure from the movable part 110 in the first embodiment.

[0053] The process of loading the toner cartridge into the image forming device is described in detail below. The movable member 997 on the image forming device is located outside the rotational driving force transmission member 999.

[0054] The first step, such as Fig.10 As shown, when the powder cartridge is not loaded into the image forming device, the forced pushing portion 112a (112b) of the power receiving component is in the anti-slip groove 126, and the support rod 124 cannot be deflected radially inward along the rotation axis of the powder cartridge body. The receiving portion 120 and the transmission portion 130 are tightly attached to each other, so that the developer stored in the powder cartridge body cannot flow out. Preferably, an elastic gasket 140 is also provided between the receiving portion 120 and the transmission portion 130 to improve the sealing performance.

[0055] In the second step, after the powder cartridge is loaded into the image forming device, since the radial distance between the abutment portion 111a (111b) and the rotation axis of the powder cartridge body is greater than the radial distance between the receiving tooth 123 and the rotation axis of the powder cartridge body, the movable component 997 on the image forming device pushes the abutment portion 111a (111b), causing the movable portion 110a (110b) to move toward the powder cartridge body, and the forced retreat portion 112a (112b) leaves the anti-slip groove 126, as shown in FIG. Fig.11 The support rod 124 can now be offset radially inwardly along the rotation axis of the powder cartridge body.

[0056] In the third step, the rotational driving force transmission component 999 on the image forming device moves toward the powder cartridge body. Due to the interference between the rotational driving force transmission component 999 and the driving teeth 123, the support rod deviates radially inward along the rotation axis of the powder cartridge body, and the receiving portion 120 meshes with the rotational driving force transmission component 999. Fig.12 shown.

[0057] In the fourth step, the movable component 997 on the image forming device moves away from the powder cartridge body. Due to the presence of the first elastic member 150, the movable portion 110a (110b) moves away from the powder cartridge body following the movable component 997. However, unlike the first embodiment, the movable component 997 limits the distance that the movable portion 110a (110b) moves away from the powder cartridge body, so that the contact portion 112a (112b) cannot completely enter the anti-slip groove 126. Fig.13At this time, the support rod 124 cannot freely deviate radially inward along the rotation axis of the powder cartridge body due to being abutted and squeezed by the abutment portion 112a (112b), but if a suitable force is applied, the end of the support rod 124 close to the anti-slip groove 126 and the receiving tooth 123 can still slightly deviate radially inward along the rotation axis of the powder cartridge body.

[0058] In the fifth step, the image forming device drags the transmission part 130 or the powder cartridge body to move in a direction away from the rotational driving force transmission component 999 (the same direction as the powder cartridge body in the third step). Since the radial inward displacement of the support rod 124 along the rotation axis of the powder cartridge body is limited, the force required to disengage the receiving part 120 from the rotational driving force transmission component 999 is much greater than the friction between the receiving part 120 and the transmission part 130, and a gap will appear between the receiving part 120 and the transmission part 130, which allows the developer stored in the powder cartridge body to flow out. Fig.14 After that, the image forming device can transmit the rotational driving force to the receiving part 120 through the rotational driving force transmission component 999, and then transmit it to the transmission part 130 through the transmission rod 125 and the protruding block 132, and finally transmit it to the powder cartridge body, so that the developer stored in the powder cartridge body can flow out continuously.

[0059] The process of removing the power receiving component from the image forming device is basically the same as the removal process in the first embodiment, and will not be described in detail here. The advantage of this design in this embodiment is that in some models of machines, the rotating driving force transmission component can still be displaced a short distance toward the powder cartridge body during the removal of the powder cartridge from the image forming device due to problems such as accuracy, and the solution in this embodiment is easier to remove the powder cartridge than the solution in the first embodiment.

[0060] Fig.15 is the movable portion 110a, Fig.16 The movable part 110b is an active part. Both of these active parts can be used in the solution of this embodiment. The difference is that the contact part 111b of the movable part 110b is less likely to be deformed and damaged than the contact part of the movable part 110a, and a reinforcing rib 113b is provided near the forced pushing part 112b. The use of these two different active parts mainly depends on factors such as the size of the power receiving component, the amount of developer contained in the powder cartridge, and the cost constraints of products of different qualities.

[0061] Embodiment 4

[0062] This embodiment mainly provides another movable part, a first movable part 110c1 and a second movable part 110c2, and other parts are the same as the power receiving component in the third embodiment.

[0063] like Fig.17 , Fig.18As shown, the first movable part 110c1 and the second movable part 110c2 involved in this embodiment. The first movable part 110c1 and the second movable part 110c2 are independent of each other and can both complete the function of the movable part 110. When the first movable part 110c1 and the second movable part 110c2 are assembled and installed on the power receiving component, an elastic member is provided between the first movable part 110c1 and the second movable part 110c2 and the receiving part 120. Due to the effect of the elastic member and the limitation of the anti-slip groove 126 on the receiving part 120, the combination of the first movable part 110c1 and the second movable part 110c2 is located on the same plane at this time, and its combined structure is the same as the movable part 110b ( Fig.16 ) structure. When the image forming device is working normally, the structures of the first movable part 110c1 and the second movable part 110c2 are also the same, which is basically the same as the power receiving part in the third embodiment. Fig.17 a. Fig.18 As shown in a.

[0064] However, when the internal components of the image forming device break or deform due to long-term operation, or when the internal components of the image forming device interfere with the movable part due to precision problems in the production process of the image forming device, if the movable part is an integrated structure, the movable part will be restricted in displacement and cannot work normally, and the toner cartridge cannot be installed normally, affecting electronic imaging. However, in this embodiment, if the second movable part 110c2 is restricted in displacement, the first movable part 110c1 can still perform the function of the movable part normally, so that the toner cartridge can work normally. Fig.17 b, 18b; similarly, when the first movable portion 110c1 is restricted from displacement, the second movable portion 110c2 can still normally complete the function of the movable portion, so that the powder cartridge can work normally, such as Fig.17 c, as shown in 18c.

[0065] For example, in the fourth step of the third embodiment, when the powder cartridge is installed on the image forming device, during the process in which the movable component 997 on the image forming device moves away from the powder cartridge body, if the second movable portion 110c2 is restricted from displacement, the first movable portion 110c1 can still move normally in the direction away from the powder cartridge body and restrict the movable portion 120, so that the movable portion 120 cannot be disengaged from the rotational driving force transmission component 999 on the image forming device, as shown in FIG. Fig.19 , Fig. 20 As shown, the fifth step can be continued to allow the developer to flow out normally. Fig.19 , Fig. 20 The status shown in Fig.17 b, the same as shown in 18b, Fig.17 c. Fig.18 The state shown in c is similar to this and will not be described again here.

[0066] It is worth mentioning that in this embodiment, when the first movable part 110c1 is pushed to the maximum distance in the direction of the powder cartridge body and the first movable part 110c1 is fixed, the distance that the second movable part 110c2 can move away from the powder cartridge body relative to the first movable part 110c1 is greater than or equal to the displacement of the second movable part 110c2 pushed by the movable part 997 on the image forming device, so as to ensure that Fig.17 c. Fig.18 c, when the first movable portion 110c1 is restricted from displacement, the second movable portion 110c2 can move a sufficient distance away from the powder cartridge body, thereby preventing the support rod 124 on the transmission portion 120 from deviating radially inwardly about the rotation axis of the powder cartridge body.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
