DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0031] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0032] Example 1

[0033] Although the existing separate imaging unit reduces parts waste to a certain extent, in order to ensure the sealing of the toner, some reusable and high-value components such as the developing roller, developing scraper, and powder supply roller still need to be discarded, which leads to high cost of use.

[0034] In view of this, the present invention provides a toner cartridge assembly 100, comprising a toner cartridge frame 110, a powder outlet seal 120 and a toner cartridge sealing slide 130; the toner cartridge frame 110 is provided with a powder outlet; one side of the powder outlet seal 120 is connected to the toner cartridge frame 110, and the other side is in contact with the toner cartridge sealing slide 130; the powder outlet seal 120 is provided with a first through hole 121, and the first through hole 121 is connected to the powder outlet; the toner cartridge sealing slide 130 is provided with a first hole 131, and the toner cartridge sealing slide 130 can move relative to the toner cartridge frame 110 and has a first state and a second state; in the first state, the toner cartridge sealing slide 130 blocks the first through hole 121; in the second state, the first hole 131 is connected to the first through hole 121.

[0035] The toner cartridge assembly 100 provided by the present invention opens and closes the powder outlet through the cooperation of the toner cartridge sealing slide 130 and the powder outlet seal 120, thereby preventing toner from spilling out. This makes the toner cartridge assembly 100 an independent structure that is easily disassembled and assembled. After the toner is used up, the toner cartridge frame 110 can be sealed by the toner cartridge sealing slide 130 to prevent residual toner from entering the environment. This reliable and convenient sealing method allows for convenient opening and closing of the powder outlet and prevents toner from spilling out, without causing environmental pollution. When in use, only the toner cartridge assembly 100 needs to be replaced; the remaining components, such as the developing roller, developing scraper, and powder supply roller, can continue to be used, thus avoiding waste of parts and materials and reducing production and use costs.

[0036] The following combination Figure 1-Figure 4 The structure and shape of the toner cartridge assembly 100 provided in this embodiment are described in detail:

[0037] In the optional solution of this embodiment, Figure 1 、 Figure 2 、 Figure 3 As shown, the toner cartridge assembly 100 includes a toner cartridge frame 110, a toner cartridge sealing slide 130, a powder outlet seal 120, a toner buffer support 150, and a toner cartridge slide seal 140. Specifically, the toner cartridge frame 110 is used to store toner, and a powder outlet is provided on the lower side of the toner cartridge frame 110 for supplying powder.

[0038] The toner cartridge sealing slide 130 is slidably connected to the toner cartridge frame 110. A first hole 131 is formed on the toner cartridge sealing slide 130. As the toner cartridge sealing slide 130 moves, the first hole 131 is aligned with the powder outlet, and toner can flow out of the toner cartridge frame 110. When the first hole 131 is misaligned with the powder outlet, the powder outlet is closed and the toner is sealed in the toner cartridge frame 110.

[0039] In order to ensure that the toner cartridge sealing slide 130 is sealed to the powder outlet, a powder outlet seal 120 is provided on the side of the toner cartridge frame 110 close to the toner cartridge sealing slide 130. A first through hole 121 connected to the powder outlet is opened on the powder outlet seal 120 to ensure that the toner passes through the toner cartridge sealing slide 130 and abuts against the powder outlet seal 120 to ensure the seal between the two, and prevent the toner remaining in the first hole 131 from scattering due to the movement of the toner cartridge sealing slide 130, thereby polluting the environment.

[0040] Furthermore, the powder outlet seal 120 is made of an elastic material, and the powder cartridge sealing slide 130 presses the powder outlet seal 120 toward the powder cartridge frame 110 to cause elastic deformation, thereby improving the sealing effect. The elastic material may be rubber, polyurethane, or other materials.

[0041] The toner buffer support 150 is connected to the toner cartridge frame 110 and is configured as an open frame. The toner cartridge slide cover seal 140 is bonded to the side of the toner cartridge sealing slide cover 130 facing away from the powder outlet seal 120. The side of the toner cartridge slide cover seal 140 facing away from the toner cartridge sealing slide cover 130 abuts against the toner buffer support 150. Specifically, the toner buffer support 150 includes a U-shaped plate and a connecting plate. One side of the U-shaped plate is open and connected to the connecting plate. The connecting plate is provided with a through hole for connecting to the toner cartridge frame 110. The toner cartridge slide cover seal 140 abuts against the bottom plate of the U-shaped plate.

[0042] In this embodiment, the toner cartridge sliding cover seal 140 defines a powder storage hole 141, which communicates with the first hole 131. In the first state, the powder storage hole 141 and the toner buffer support 150 form an upward-opening powder storage trough. Specifically, the powder storage hole 141 and the bottom plate of the U-shaped plate form the powder storage trough. When the toner cartridge sealing slide 130 moves, closing the powder outlet, any toner remaining in the first hole 131 falls into the powder storage trough and is stored, preventing spillage.

[0043] Furthermore, the toner cartridge slide cover seal 140 is made of an elastic material, and the toner cartridge seal slide cover 130 presses the toner cartridge slide cover seal 140 toward the toner buffer support 150 to cause elastic deformation, thereby improving the sealing effect. The elastic material may be rubber, polyurethane, or other materials.

[0044] The working process of the toner cartridge assembly 100 is as follows:

[0045] In the first state, the powder outlet is closed, and first hole 131 is offset from first through-hole 121. Powder outlet seal 120 and cartridge slide seal 140 elastically deform to apply pressure to cartridge seal slide 130. Friction secures cartridge seal slide 130, maintaining the powder outlet closed. At this point, powder outlet seal 120 seals the upper end of first hole 131, effectively sealing the powder reservoir, preventing the escape of toner stored in the reservoir.

[0046] When switching from the first state to the second state, the toner cartridge sealing slide 130 is moved, and the toner cartridge slide seal 140 moves synchronously with the toner cartridge sealing slide 130 so that the first hole 131 is aligned with the powder outlet. At this time, toner can be supplied through the powder outlet, the first through hole 121 and the first hole 131 under the action of gravity, and the powder outlet is opened.

[0047] When the second state is converted to the first state, that is, when the powder outlet is closed, due to the sealing effect of the powder outlet seal 120 and the toner cartridge sliding cover seal 140, the residual toner in the first hole 131 and the powder storage hole 141 is carried and falls into the toner buffer bracket 150. At this time, the powder outlet seal 120, the first hole 131 and the powder storage tank form an enclosed space to seal the toner. There is also some toner between the toner cartridge sliding cover seal 140 and the bottom plate of the U-shaped plate of the toner buffer bracket 150. Due to the extrusion between the two, the toner is squeezed and enclosed in the contact surface of the two.

[0048] Example 2

[0049] In an optional solution of this embodiment, the separate imaging unit includes the toner cartridge assembly 100 in the first embodiment and a developing assembly 200 disposed below the toner cartridge assembly 100. Figure 5 As shown, the toner cartridge assembly 100 and the developing assembly 200 are detachably connected.

[0050] The following combination Figures 1-9 The structure and shape of the separate imaging unit provided in this embodiment are described in detail:

[0051] The structure and shape of the developing assembly 200 are as follows:

[0052] The developing assembly 200 includes a developing frame 210, a locking rod 220, a locking handle 230, a developing sealing slide 240, a toner cartridge locking spring 250, a developing slide control spring 260 and a powder inlet patch 270. Figure 6 、 Figure 7 、 Figure 8 shown.

[0053] The developing frame 210 includes a developing cover 211 and a developing base 212. The developing base 212 defines a sliding slot 212a, within which a locking lever 220 is mounted and moves. The developing cover 211 connects to the developing base 212, sealing the sliding slot 212a and thereby securing the locking lever 220. The developing cover 211 has latching slots at both ends along the length of the sliding slot 212a. The toner cartridge frame 110 has corresponding latching blocks. The toner cartridge frame 110 moves perpendicular to the length of the movable slot to engage the latching blocks.

[0054] The direction in which the card block is inserted into the card slot is the first direction.

[0055] Furthermore, a first protrusion 111 is provided on the lower side of the toner cartridge frame 110 , and the first protrusion 111 is used to engage with the developing assembly 200 to achieve installation of the toner cartridge assembly 100 and the developing assembly 200 .

[0056] Accordingly, the locking lever 220 is provided with a second protrusion 221. The second protrusion 221 can overlap and contact the first protrusion 111 in the first direction, thereby preventing the locking block from moving in the opposite direction to the first direction, which would cause the locking block to disengage from the slot and thus lock the toner cartridge assembly 100 and the developer assembly 200. To ensure the locking effect, two first protrusions 111 and a second protrusion 221 are provided along the second direction.

[0057] The locking handle 230 is hinged to the developing base 212 and abuts against the locking rod 220. Rotating the locking handle 230 can push the locking rod 220 to move and make the second protrusion 221 overlap with the first protrusion 111 to complete the locking.

[0058] The developing upper cover 211 is provided with a long hole, and the second protrusion 221 passes through the rectangular long hole and can move along the rectangular long hole.

[0059] The direction in which the locking handle 230 pushes the locking rod 220 to move is the second direction, and the second direction and the first direction are perpendicular to each other.

[0060] Furthermore, a spring slot 212b is provided on the developing base 212, and a toner cartridge locking spring 250 is disposed in the spring slot 212b. One end of the toner cartridge locking spring 250 is connected to the developing frame 210, and the other end is connected to the locking rod 220, for applying a force opposite to the second direction to the locking rod 220, and the line of action of the thrust applied by the locking rod 220 to the locking handle 230 driven by the toner cartridge locking spring 250 passes through the hinge point between the locking handle 230 and the developing base 212, so as to achieve self-locking and prevent the locking handle 230 from rotating under the action of the toner cartridge locking spring 250, resulting in locking failure. In this embodiment, the toner cartridge locking spring 250 is configured as a tension spring. Figure 8 As shown, the locking lever 220 is provided with a connecting protrusion 223 for connecting with the toner cartridge locking spring 250 .

[0061] Furthermore, the developer upper cover 211 is provided with a powder inlet, which can be connected to the powder outlet to allow toner to enter the developer assembly 200. One end of the developer sealing slide 240 is clamped to the locking rod 220, and the other end is clamped to the toner cartridge sealing slide 130. Therefore, when the locking rod 220 moves, it can simultaneously drive the developer sealing slide 240 and the toner cartridge sealing slide 130 to move. When the toner cartridge assembly 100 is locked and unlocked, the powder outlet can be opened and closed at the same time, thereby improving the efficiency of disassembly and assembly.

[0062] Specifically, the developer sealing slide 240 is provided with a first stopper 241 and a second stopper 242, and the toner cartridge sealing slide 130 is provided with corresponding first and second top blocks 132 and 133. When locked, the first stopper 241 abuts against the first top block 132, applying a thrust to the first top block 132, thereby switching from the first state to the second state and opening the powder outlet. When unlocked, the second stopper 242 abuts against the second top block 133, applying a thrust to the second top block 133, thereby switching from the second state to the first state and closing the powder outlet. The locking lever 220 is provided with a stopper slot 222 for engaging with the developer sealing slide 240.

[0063] The developer seal slide 240 is provided with a guide rod 243, and a developer slide control spring 260 is mounted on the guide rod 243 to prevent the spring from twisting and bending. One end of the developer slide control spring 260 abuts the developer upper cover 211, and the other end abuts the developer seal slide 240. This spring applies a force opposite to the second direction to the developer seal slide 240, assisting in the movement of the locking lever 220 during unlocking. Specifically, the developer slide control spring 260 is configured as a compression spring.

[0064] Furthermore, to prevent residual toner from the first hole 131 and the powder storage hole 141 from spilling out when the powder outlet is closed, a powder inlet patch 270 is provided on the developer upper cover 211. Specifically, the powder inlet patch 270 abuts the side of the toner cartridge slide seal 140 facing away from the toner cartridge sealing slide 130. Simultaneously, the powder inlet patch 270 extends into the toner cartridge buffer support 150 and overlaps the bottom plate of the U-shaped plate. This allows residual toner to be scraped into the toner cartridge buffer support 150 by the toner cartridge sealing slide 130, preventing it from escaping into the environment. If the powder inlet patch 270 is docked with the toner cartridge buffer support 150, residual toner could escape from the joint when the toner cartridge sealing slide 130 is moved. Furthermore, a gap is provided between the developer sealing slide 240 and the powder inlet patch 270 to prevent the developer sealing slide 240 from scraping residual toner from the powder inlet patch 270.

[0065] To avoid interference during installation, corresponding notches are provided on the side of the U-shaped plate to ensure movement of the toner cartridge assembly 100 along the first direction.

[0066] The working process of the separate imaging unit provided in this embodiment is as follows:

[0067] During installation, the toner cartridge assembly 100 is inserted into the developer assembly 200 in a first direction, so that the toner cartridge frame 110 is locked to the developer upper cover 211. The locking handle 230 is then rotated, causing it to push the locking lever 220 in a second direction, causing the first protrusion 111 and the second protrusion 221 to overlap, thereby locking the toner cartridge assembly 100 and the developer assembly 200 together. At this point, the toner cartridge locking spring 250 is stretched, and the developer slide control spring 260 is compressed. The toner cartridge locking spring 250 applies a force opposite to the second direction to the locking lever 220, and the developer slide control spring 260 applies a force opposite to the second direction to the developer sealing slide 240.

[0068] As locking lever 220 moves, the developer sealing slide 240, the toner cartridge sealing slide 130, and the toner cartridge slide seal 140 also move simultaneously, opening the powder outlet and connecting it to the powder inlet. After locking, the spring force of locking lever 220 applies a thrust to locking handle 230. Because the force's line of action passes through the hinge point between locking handle 230 and developer base 212, locking handle 230 does not rotate and remains locked under the force, preventing it from being unlocked due to vibration or other factors.

[0069] When removing the toner cartridge assembly 100, the locking handle 230 is rotated to disengage it from the locking lever 220. At this point, under the action of the spring force, the locking lever 220 moves in a direction opposite to the second direction and remains in contact with the locking handle 230. Simultaneously, the developer sealing slide 240 and the toner cartridge sealing slide 130 move, closing the powder outlet. During the closing process, any remaining toner in the first hole 131 and the powder storage hole 141 moves to the toner buffer support 150 and is stored in the powder storage trough and the contact surface between the toner cartridge slide seal 140 and the toner buffer support 150. The powder storage trough is sealed by the powder outlet seal 120, preventing any remaining toner from the toner cartridge assembly 100 from spilling into the environment.

[0070] The detachable imaging unit provided in this embodiment is achieved through the detachable connection between the toner cartridge assembly 100 and the developing assembly 200, so that after the toner is consumed, only the toner cartridge assembly 100 needs to be replaced, and there is no need to discard other related parts, which greatly reduces the waste of parts and lowers the cost of use; at the same time, the design of the sealing structure effectively prevents toner from being scattered into the environment, avoiding harm to the environment; the powder outlet can be opened or closed simultaneously when installing or removing the toner cartridge assembly 100, which improves the efficiency of disassembly and assembly, and at the same time avoids the scattering of toner due to forgetting to close the powder outlet after disassembly, thereby improving safety.

[0071] It should be noted that due to the shape of the locking handle 230 in this embodiment, when the locking handle 230 is rotated, the locking rod 220 moves in the second direction and then moves in the opposite direction. That is, during installation, the locking rod 220 first moves in the second direction. As the locking handle 230 rotates to the self-locking position, the locking rod 220 also moves in the opposite direction, ultimately aligning the first protrusion 111 and the second protrusion 221. In this embodiment, the rotation angle of the locking handle 230 is 90 degrees. During removal, the locking rod 220 first moves a short distance in the second direction and then moves in the opposite direction to unlock the lock.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above 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 invention.
