- Fig. 3 is a right side view of Fig. 1
- 6 is a left side view of FIG. 5;
- First Embodiment Referring to FIG. 1, the upper surface of the cover 101 is a flat surface, the left end has a conductive shaft 134 formed by the developing roller shaft naturally extending, and the right end is a gear set.
- the inner cavity surrounded by the box body 102 and the cover 101 includes a powder silo 103.
- the powder silo has a stirring device.
- the stirring device is composed of a stirring shaft 106 and a stirring frame 104 fixed on the shaft.
- the stirring shaft 106 is supported by the stirring shaft 106.
- the bridge gear 120 and the driving position 123 on the gear shaft are also installed on the side wall, and simultaneously mesh with the large wheel of the bridge gear 112, the powder feed roller shaft end gear 121, and the developing roller shaft end gear 122.
- the driving position 113 When the driving position 113 receives the driving force, it drives the big wheel 112, the gear 119 and the gear 120, and the gear 120 meshes with the gear 121 and the gear 122 through its coaxial gear; when the driving position 123 receives the driving force, it passes all the way
- the gear 112 is transmitted to the gear 119, and the other is transmitted to the gears 120 and 121, so that the toner cartridge can work normally regardless of the driving power input from that driving position.
- the lock lever 115 with the hook end 118 has two extreme positions, one is the lock position shown in FIG. 3 When in this position, the internal force of the torsion spring 114 is the smallest, and the hook 118 is hooked in the lock hole on the bottom plate of the photosensitive drum box, so that the toner cartridge cannot move up and down relative to the photosensitive drum box; the other is a human push and the lock lever 115 is integrated
- the pressure plate 116 is released, the internal force of the torsion spring 114 is overcome, and the lock lever is rotated clockwise around the hinge in FIG. 3 to the position where the hook 118 is released from the lock hole, thereby releasing the constraint of the toner container with respect to the photosensitive drum container in the up-down direction.
- gear shafts 126 and 131 there are integral gear shafts 126 and 131 on the side wall of the box body, and gears 127 and 120 with driving positions 113 and 123 are respectively installed.
- the bearing housing 111 has two shaft holes 128 and 129 correspondingly. Fastened by three screws 124, 125, 130.
- an elastic block 132 is provided at the front end of the side wall of the cartridge body, and the curved end of the elastic block 132 enters the cartridge body.
- the conductive shaft 134 in FIG. 1 is maintained in an optimal electrical connection with the printer.
- Second embodiment For simplicity, the following (including the third embodiment) are the same as the prior art with respect to the structure and working mechanism of the box body, powder bin, stirring device, powder feeding device, and developing device.
- the same flat cover structure, double driving bit structure, etc. will not be described in detail, and only the different structural forms of each example will be described in detail.
- FIG. 5 there is an elastic guide block 210 on the left side of the front of the box body 240.
- One end of two curved elastic springs 220 is symmetrically fixed at the bottom of the box body 240.
- the free end of the elastic spring plate 220 is located behind the box body 240.
- Each elastic reed 220 has two holes at the fixed end.
- the process of installing the toner cartridge 240 into the photosensitive drum cartridge 250 is very simple. Holding the rear part of the toner cartridge 240 (the left end of the figure), the front end is slanted downward into the photosensitive drum cartridge 250, and then The hook 233 is pushed downward during this process, and the hook 233 is squeezed back and slides down the inside of the rear wall of the photosensitive drum cartridge 250. When it is in place, the hook 233 snaps into the hole 252 on the photosensitive drum cartridge 250.
- the elastic reed 220 is pressed between the rear walls of the two cartridges, so that the rear end of the toner cartridge 240 generates two component forces upward and forward relative to the photosensitive drum cartridge 250.
- the drum 251 is positioned forward and backward, and the upward disengagement force is canceled by the hook 233 of the lock lever being hooked in the hole 252 corresponding to the photosensitive drum cartridge 250, thereby achieving vertical positioning.
- the lock lever When separating, press the lock lever When the hook 233 exits the hole 252 in position, the rear end of the toner cartridge jumps out of the photosensitive drum cartridge 250 under the upward force of the elastic reed 220.
- the fixed guide block 214 is also integrally formed on the container body. The distance between the end of the fixed guide block 214 and the end of the elastic guide block 210 is slightly larger than the width between the inner wall of the photosensitive drum box 250.
- an elastic positioning block 313 is provided on the left side of the front of the box body 301, and a fixed positioning block (not visible in the figure) is formed on the right side symmetrically and integrally. They are topped between the parallel warehouse walls to ensure the right and left positioning of the powder container. Forced pushing mechanisms 311 are symmetrically arranged at the rear ends of the two sides of the box body. 301 gains forward thrust, so that the display Positioning is ensured between the shadow roller and the photosensitive drum in the cartridge compartment.
- the structure of the pushing mechanism 311 is as follows, one with the box body 301
- the side is integrally formed or ultrasonic; 1: the early-connected support 319 has two upper and lower sliding grooves 320, the slider 316 has two convex ribs 318 that cooperate with the sliding groove, and a compression spring 317 is arranged between the slider 316 and the support 319
- the slider 316 also has an outwardly-shaped bending portion, and a ratchet tooth 315 is provided on the bending portion.
- the developing roller in the cartridge 301 contacts the photosensitive drum 323, and The end is pressed into contact with the buckling position 322 of the photosensitive drum cartridge by the bending portion of the elastic pushing device 311, that is, the ratchet teeth 315 are locked on the buckling position 322 under the elastic force of the spring.
- the operator can hold the rear part 321 of the box body and lift it upward forcefully, so that the ratchet teeth 315 which overcome the spring force retracts to the right and disengages from the buckling position 322. Under the guidance of the curved portion of the elastic pushing device 311, it jumps up. Referring to FIG. 13 and FIG.
- a positioning block 329 located on the right side of the bottom front end of the box body can be seen.
- a protective cover 330 is used to protect the developing roller.
- the elastic positioning block 313 is composed of a fixed seat, a slider that can slide in the fixed seat, and a spring pressed between the slider and the fixed seat. The slider protrudes from the right side of the box body and is the most Right end.
- the method of using this embodiment is as follows. The process of installing the toner cartridge into the cartridge compartment is very simple. Holding the rear part of the toner cartridge, the front end is slanted into the cartridge compartment, and then the rear end of the toner cartridge is pushed down and forced to push.
- the mechanism 311 is pressed on the holder of the cartridge compartment, so that the rear end of the toner cartridge generates two component forces upward and forward relative to the cartridge compartment.
- the front end abuts against the photosensitive drum to achieve forward and backward positioning, and the upward release force is Up and down positioning is achieved by the ratchet teeth engaging with the buckle.
- the toner cartridge provided by the present invention is installed in a printer having that driving position, and can reliably receive power for work, and solves the problem of allowing the printer power output to recognize a specific toner cartridge. It is beneficial to manufacturers and businesses, and it is convenient for printer users.
- a fixed guide block and an elastic guide block are used to achieve smooth introduction into the photosensitive drum box; the front and back and up and down positioning are realized by a relatively simple structure of the lock lever mechanism, and at the same time, it has a reliable operation and a failure rate Low advantages.
