Description

Technical Field

[0001] The present application relates to the technical field of image forming, and in particular to a powder cartridge. Background Art

[0002] An electronic imaging device is a device that forms an image on a recording material through electrophotographic imaging processing technology, such as an electronic photocopy, a laser printer, an electronic photo printer, a fax machine, a word processor, etc. A toner cartridge for supplying a developer (such as toner) can be detachably installed inside the device. As the developer continuously participates in electronic imaging, when the developer in the toner cartridge is exhausted, the user needs to replace the toner cartridge in time or inject new developer into the toner cartridge, which makes the toner cartridge one of the frequently replaced consumable parts in electronic imaging.

[0003] In the prior art, the powder cartridge is installed and removed in a developer replenishing device for receiving developer in an electronic imaging device, and each installation and removal operation of the powder cartridge in the developer replenishing device involves connecting and disconnecting the powder outlet of the powder cartridge with the powder receiving port of the developer replenishing device.

[0004] Figure 1 The present invention is an exploded view of a powder cartridge that can be detachably mounted on a developer replenishing device disclosed in the prior art. The powder cartridge 1 comprises: a powder cartridge body 2 for containing developer, a powder discharge structure 3 located at a first end 21 in the length direction of the powder cartridge body 2, and a slide plate 4 that slides relative to the powder discharge structure 3, wherein the powder discharge structure 3 comprises an upper flange portion 3a, a lower flange portion 3b, and the powder discharge structure 3 also comprises a stirring frame, a powder mixing portion, a powder discharge port and other structures for discharging the carbon powder in the powder cartridge body 2, and different structures can be designed according to different discharge principles. Figure 2a-2c middle, Figure 2a is a schematic diagram of the structure of a developer replenishing device; Figure 2b A partially enlarged cross-sectional view of a developer replenishing device; Figure 2c The developer replenishing device 8 at least includes a developer receiving portion 11, a first slide plate clamping portion 8a and a second slide plate clamping portion 8b, and the developer receiving portion 11 includes a receiving port 11a, a coupling portion 11b for opening and closing the receiving port 11a, and a sealing member 13, wherein a stopper 15 located in the receiving port 11a is used to seal the receiving port 11a, and the developer receiving portion 11 is driven to rise and fall by the coupling portion 11b so that the receiving port 11a and the stopper 15 are in a spaced and contacted state, thereby opening and closing the receiving port 11a, and an elastic member 12 may also be provided so that the coupling portion 11b overcomes the elastic force of the elastic member 12 to rise and fall under the elastic force of the elastic member 12. Figure 3a-3c, the guide rail structure on the lower flange portion 3b of the powder discharge structure 3 is shown, and the process of the guide rail structure being used to lift the joint portion 11b in the developer replenishing device to open the receiving port 11a of the developer replenishing device. The guide rail structure includes a rising first portion 3b2 and a second portion 3b4. As the powder cartridge 1 is installed in the direction of arrow A, the joint portion 11b is guided by the first portion 3b2 to rise so that the receiving port 11a is opened, and continues to move on the second portion 3b4 to a position where the powder discharge port (not shown) in the powder cartridge is fully opened, so that the powder discharge port in the powder cartridge and the receiving port 11a form a through developer discharge channel. In the process of disassembling the powder cartridge, similarly, when the powder cartridge 1 moves in the opposite direction B to the installation direction A, the powder discharge port and the receiving port 11a in the powder cartridge are closed respectively. However, in the process of guiding the movement of the coupling portion 11b by the second portion 3b4 of the guide rail, since the receiving port 11a has been fully opened and has risen to a sufficient height, it will successively fit the corresponding parts of the bottom of the powder outlet structure 3 and the slide plate 4 and continue to move along the A / B direction with the installation / disassembly action of the powder cartridge. Even if the seal and position are aligned, relative displacement is still inevitable. Since the developer is an extremely light particulate powder, it is easy to cause the developer to fly due to the elastic force caused by the elastic deformation of each seal when relative displacement occurs due to friction and vibration. Summary of the invention

[0005] In order to overcome the defects of the prior art mentioned above, the main purpose of the present application is to provide a powder cartridge that can prevent the developer from scattering during the installation process.

[0059] Embodiment 1

[0060] This embodiment provides a powder cartridge that can be detachably installed in an electronic imaging device. The powder cartridge of the present application is similar to the installation method of the powder cartridge of the prior art, and is also installed on the developer replenishing device 8 located in the electronic imaging device, such as Figure 2a-2c .

[0061] Reference Figure 4-Figure 6 As shown, the powder barrel 100 includes a shell 110, a powder barrel body 120 and a powder discharge structure 130. The powder barrel body 120 is generally a long cylindrical structure in the present embodiment. In the extension direction of the length of the powder barrel body 120, the two ends of the powder barrel body 120 are respectively a first end 121 and a second end 122, the first end 121 is a powder discharge end, and the powder barrel body 120 has a accommodating chamber inside for storing developer. When the powder barrel 100 is installed in an electronic imaging device, the powder barrel body 120 can be driven to rotate around its rotation axis L in the electronic imaging device. The powder discharge structure 130 is connected to the first end 121, and is used to discharge the developer in the powder barrel body 120 into the electronic imaging device to participate in the development. The shell 110 is coated on the powder discharge structure 130.

[0062] Furthermore, a gear ring 123 is provided on the powder cartridge body 120. The gear ring 123 can be engaged with the electronic imaging device to obtain a rotational driving force from the electronic imaging device, thereby driving the powder cartridge body 120 to rotate around its rotation axis L and relative to the powder outlet structure 130.

[0063] The powder outlet structure 130 includes a connecting portion 160 and a fixed powder outlet plate 180. The connecting portion 160 is connected to the first end 121 of the powder barrel body 120, and the connecting portion 160 is provided with a powder outlet 140 (see Figure 7 The fixed powder discharge plate 180 is connected to the connecting portion 160, and the fixed powder discharge plate 180 has an opening 181. Figure 6 In the Z direction in the first direction), the projection of the powder outlet 140 at least partially overlaps with the projection of the opening 181. In this embodiment, the projection of the powder outlet 140 in the first direction completely falls within the projection of the opening 181 in the first direction. The mechanical structure inside the powder outlet structure 130 can be a structure set according to different powder feeding principles in the prior art, which will not be described in detail here.

[0064] In this embodiment, the fixed powder discharge plate 180 and the powder discharge port 140 are both located at the bottom of the powder discharge structure 130. Specifically, the powder discharge port 140 can be opened at the bottom of the connecting portion 160 and closer to the rotation axis L than the fixed powder discharge plate 180. The opening 181 is opened at the bottom of the fixed powder discharge plate 180. The shape and size of the opening 181 are larger than the powder discharge port 140. In the first direction, the powder discharge port 140 is located above the opening 181, that is, the distance between the powder discharge port 140 and the rotation axis L is smaller than the distance between the opening 181 and the rotation axis L, so that the developer stored in the powder cartridge body 120 can be discharged to the outside of the powder cartridge through the powder discharge port 140 and the opening 181.

[0065] The powder discharge structure 130 further includes a movable powder discharge plate 190. In the first direction, the movable powder discharge plate 190 is disposed between the connecting portion 160 and the fixed powder discharge plate 180. A powder discharge hole (not shown) is disposed on the movable powder discharge plate 190. When the powder cartridge is installed into the developer replenishing device in the electronic imaging device, the first slide plate clamping portion 8a and the second slide plate clamping portion 8b can clamp the two side bumps (not shown) of the movable powder discharge plate 190, so that the movable powder discharge plate 190 is engaged with the developer replenishing device 8 and remains in a fixed state. The fixed powder discharge plate 180 is moved along the second direction ( Figure 6 The installation action is continued in the +X direction) to make the movable powder discharge plate 190 and the fixed powder discharge plate 180 move relative to each other. When the opening 181 on the fixed powder discharge plate 180 gradually overlaps with the powder discharge port 140 through the powder discharge hole on the movable powder discharge plate 190, a discharge channel is formed. The developer stored in the powder cartridge body 120 can be discharged to the outside of the powder cartridge through the powder discharge port 140, the powder discharge hole on the movable powder discharge plate 190 and the opening 181.

[0066] When the powder cartridge is installed in the electronic imaging device, in order to facilitate the movement of the developer receiving portion, the powder discharge structure 130 further includes a guide portion 131, through which the guide portion 131 guides the joint portion 11b of the developer receiving portion 11 in the developer replenishing device 8, and opens the receiving port 11a with a simple structure and stroke. Figure 6 As shown, the fixed powder outlet plate 180 has a first end body 182 away from the powder barrel body 120, and a second end body 183 close to the powder barrel body 120. In the direction of the rotation axis L, the two sides of the fixed powder outlet plate 180 are mirror-imaged with side walls bent upward, and the guide portion 131 is a protruding structure extending from the side walls on both sides of the fixed powder outlet plate 180.

[0067] Specifically, the guide portion 131 is connected to the side wall of the fixed powder outlet plate 180, and the guide portion 131 is arranged to be straight and inclined in the direction from the first end body 182 to the second end body 183, or arranged to be curved and inclined, and the guide portion 131 has a first end 131a and a second end 131b, and the second end 131b is closer to the rotation axis L than the first end 131a, that is, in the first direction, the second end 131b is located above the first end 131a, and the second end 131b is located above the powder outlet 140. In this embodiment, at the second end 131b, the slope of the guide portion 131 is not 0, in other words, the guide portion 131 near the second end 131b is not parallel to the axis L. When the powder cartridge is installed in the electronic imaging device, the developer receiving portion moves along the guide portion 131 from the first end 131a to the second end 131b, so that the developer in the powder cartridge body 120 can flow into the electronic imaging device through the powder outlet 140 and the developer receiving portion.

[0068] Also refer to Figure 8a , Figure 8b As shown, taking the installation operation of the powder cartridge as an example, as the powder cartridge 100 is moved along the second direction ( Figure 8a +X direction in the developer replenishing device 8, Figure 8a In the embodiment, the powder cartridge is located at the first position of the receiving port 11a to be opened. The coupling portion 11b for opening and closing the receiving port 11a is located at the first end 131a of the guide portion 131. As the powder cartridge moves further along the second direction, the guide portion 131 guides the coupling portion 11b to gradually climb to the second end 131b. At this time, the upward movement of the coupling portion 11b gradually opens the receiving port 11a, and as the first slide clamping portion 8a and the second slide clamping portion 8b are clamped to the movable powder outlet plate 190, the powder outlet hole, the powder outlet 140 and the opening 181 on the movable powder outlet plate 190 gradually form a developer discharge channel, and finally the receiving port 11a and the discharge channel are matched and docked at the second end 131b. At this time, the discharge channel is located in a plane passing through the second end 131b and perpendicular to the rotation axis L, allowing the developer in the powder cartridge body 120 to flow into the electronic imaging device. That is, in Figure 8b In the embodiment, the powder cartridge is located at the second position where the discharge channel is formed and the receiving port 11a is opened, and the developer in the powder cartridge can flow smoothly into the developer replenishing device at the second end 131b. In the previous movement process, the receiving port 11a is in an incompletely opened state. Therefore, under the action of the guide portion 131, the receiving port 11a will not abut against the fixed powder discharge plate 180 or the movable powder discharge plate 190 too early during the installation of the powder cartridge, and the developer will not be scattered due to friction vibration and other reasons during the installation and movement of the powder cartridge.

[0069] Embodiment 2

[0070] In this embodiment, based on the first embodiment, the powder outlet structure 130 further includes a retaining portion 132 .

[0071] Reference Figure 9-10b As shown, Fig.10a and Fig.10b They are respectively the first position in which the powder cartridge is in the receiving port 11a to be opened and the second position in which the discharge channel is formed and the receiving port 11a is opened. The powder discharge structure 130 also includes a retaining portion 132, and when the powder cartridge is installed on the electronic imaging device, the retaining portion 132 is used to limit the coupling portion. Preferably, a pair of retaining portions 132 are mirror-imaged on the side walls on both sides of the fixed powder discharge plate 180. The retaining portion 132 may be a protrusion extending outward from the side wall of the fixed powder discharge plate 180, and may be arranged outside the guide portion 131, or may be arranged on the guide portion 131. When the retaining portion 132 is arranged outside the guide portion 131, the retaining portion 132 may be an independent portion spaced a distance from the second end portion 131b of the guide portion 131, that is, the retaining portion 132 is spaced apart from the second end portion 131b of the guide portion 131, so that the coupling portion 11b moved to the second end portion 131b can be snapped into the gap between the retaining portion 132 and the guide portion 131, as Fig.10b As shown, the receiving port 11a is kept open.

[0072] In addition, the retaining portion 132 may be modified in other ways, for example, Fig.11 The thin sheet structure 133 shown, or as Fig.12 The cylindrical structure 134 shown, or a structure with a triangular, conical, regular or irregular polygonal cross section, when the powder cartridge is located at a position to form a discharge channel and open the receiving port 11a, the gap between the retaining portion 132 and the guiding portion 131 is used to keep the coupling portion 11b at the position to open the receiving port 11a. Also, when the retaining portion 132 is disposed on the guiding portion 131, the retaining portion 132 may also be a surface with a high friction coefficient located at the second end portion 131b, or as Fig.13 The groove 135 shown directly utilizes friction or groove locking to keep the engaging portion 11 b on the retaining portion, so as to maintain the position of the receiving opening 11 a.

[0073] Preferably, a chamfered structure may be provided at the second end 131b of the guide portion 131 and the contact portion of the retaining portion 132 that is engaged with the coupling portion 11b (ie, the portion located at the interval) to make it easier for the powder cartridge to detach from the engaging structure during disassembly.

When the powder cartridge is installed, the coupling portion 11b of the electronic imaging device moves along the guide rail 231c from the first end 231a to the second end 231b.

[0078] In this embodiment, the powder discharging structure 230 further includes a first force block 234, which is connected to the guide portion 231 and is located at the upper part of the second end portion 231b. The first force block 234 is used to cooperate with the coupling portion 11b. When the powder cartridge is installed on the electronic imaging device along the second direction, the coupling portion 11b and the first force block 234 can abut against each other and push the entire guide portion 231 to move along with the installation of the powder cartridge and the movement of the coupling portion, that is, push the guide portion 231 to move in a direction opposite to the second direction, that is, from a direction away from the connecting portion 260 to a direction close to the connecting portion 260 ( Fig.14 -X direction in the image.

[0079] Further, the fixed powder discharge plate 280 includes a track 284, an abutment block 285, an anti-slip block 286 and a balancing block 287.

The mating piece 231g is in an I-shaped structure and is used to be installed in the track 284. The first auxiliary block 231f is used to be installed on the upper part of the abutment block 285 in the vertical direction, and the second auxiliary block 231i is used to be installed above the balancing block 287. The first auxiliary block 231f, the second auxiliary block 231i and the I-shaped mating piece 231g work together to ensure that the guide part 231 moves as smoothly as possible and reduce shaking.

[0080] The powder discharging structure 230 further includes a locking member 232 and an elastic member 233. The locking member 232 is movably disposed on the guide portion 231, and the locking member 232 has an unlocking position and a locking position on the guide portion 231. When the locking member 232 moves in the opposite direction of the guide portion 231 along the second direction ( Fig.14 During the movement of the first force block 234 along the second direction (-X direction in the middle), the locking member 232 can extend from the guide portion 231 to limit the joint portion 11b, and the locking member 232 reaches its locking position. The elastic member 233 is arranged between the locking member 232 and the guide portion 231, and is used to act on the locking member 232. During the movement of the locking member 232 along the second direction with the guide portion 231, the elastic member 233 acts on the locking member 232 to retract the locking member 232 to release the limit on the joint portion 11b, and the locking member 232 reaches its unlocking position. Furthermore, a gap 231d is also arranged on the other side of the first force block 234 relative to the joint portion 11b installed in place, so that the locking member 232 can pass through the gap 231d.

[0081] Fig. 20 and Fig.21 The three-dimensional view of the locking member from different angles. The locking member 232 includes a stabilizing portion 232c and a second force block 232a, and the second force block 232a is connected to the stabilizing portion 232c. When the locking member 232 moves along the guide portion 231 in a direction opposite to the second direction, the stabilizing portion 232c contacts and interferes with the abutment block 285, so that the second force block 232a extends out from the gap 231d, so that it can contact and receive force with the coupling portion 11b of the electronic imaging device.

[0082] Furthermore, a first fixing portion 231h for fixing one end of the elastic member 233 is further provided on the back of the guide portion 231. Preferably, the first fixing portion 231h is a hole that does not penetrate the guide portion 231. The locking member 232 also includes a second fixing portion 232b for fixing the other end of the elastic member 233. Preferably, the second fixing portion 232b is a protruding column connected to the stabilizing portion 232c, and the elastic member 233 is a compression spring. During assembly, one end of the elastic member 233 is sleeved on the second fixing portion 232b, and the other end of the elastic member 233 is located at the first fixing portion 231h, thereby limiting the elastic member 233, that is, the elastic member 233 is located between the stabilizing portion 232c and the guide portion 231.

[0083] In order to prevent the locking member 232 from shifting in position when moving in the second direction together with the guiding portion 231, the stabilizing portion 232c can be inserted into the groove of the I-shaped fitting 231g, thereby ensuring that there is no relative movement between the locking member 232 and the guiding portion 231 as much as possible.

[0084] Fig. 22 This is a schematic diagram of the powder discharge structure before the powder cartridge is loaded into the electronic imaging device. Fig.23 for Fig. 22 Schematic diagram of the internal structure with the guide removed. Fig.24 This is a schematic diagram of the powder discharge structure when the powder cartridge is installed in place in the electronic imaging device. Fig.25 for Fig.24 Schematic diagram of the internal structure with the guide removed. Fig. 22 and Fig.23 As shown, before the powder cartridge is installed into the electronic imaging device, the locking member 232 is located between the anti-dropping block 286 and the abutment block 285, and the locking member 232 does not extend relative to the guide portion 231. During the installation process, the coupling portion 11b of the electronic imaging device moves along the first end 231a of the guide portion 231 toward the second end 231b. Afterwards, the coupling portion 11b will abut against the first force block 234, and drive the entire guide portion 231 and the locking member 232 to move along the track 284. Due to the contact and interference between the locking member 232 and the abutment block 285, the second force block 232a gradually extends out of the gap 231d, and the elastic member 233 becomes compressed. When the powder cartridge is installed, the coupling portion 11b moves to the installation position set by the electronic imaging device, reaching the installation position. Fig.24 and Fig.25 At this time, as in the first embodiment, a discharge channel can be formed at the plane passing through the second end 231b of the guide rail and perpendicular to the rotation axis, allowing the developer in the powder cartridge to flow into the electronic imaging device, and the powder cartridge can work normally. When the powder cartridge is taken out after the work is completed, the coupling portion 11b contacts the second force block 232a and moves along the track 284 in a direction opposite to the second direction (installation direction) and drives the guide portion 231 and the locking member 232 to move together until it moves to Fig. 22 and Fig.23 , the locking member 232 no longer contacts and interferes with the abutting block 285, and the elastic member 233 releases its elastic potential energy to push the second force-bearing block 232a to retract from the gap 231d and no longer contacts the coupling portion 11b. Then, the coupling portion 11b moves along the second end 231b of the guide rail 231c to the first end 231a, thereby completing the separation of the coupling portion 11b during the process of removing the powder cartridge.
