Detailed Description

The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 shows a first embodiment of the cartridge of the present invention in a perspective view. The cartridge includes a powder bin 104 and a waste powder bin 101. The toner stored in the toner hopper 104 is used for printing, and the waste toner hopper 101 is used for accommodating waste toner generated in the toner cartridge printing process. The toner cartridge shown in fig. 1 is provided with a toner replenishing container connecting hole 103, and a toner hopper cover 102 is used for sealing the toner replenishing container connecting hole 103. The toner replenishing container connecting hole 103 is arranged on the toner hopper 104 of the toner cartridge and faces the toner cartridge assembly opening of the printing device where the toner cartridge is located after the toner cartridge is assembled into the printing device. The toner cartridge mounting port is an opening provided in the printing apparatus so that the toner cartridge is mounted in the printing apparatus from above to below in the direction of gravity, or from obliquely above to below in the direction of gravity. The state of the cartridge shown in fig. 1 is a state that is assumed when the cartridge is assembled into the printing apparatus.

The surface of the toner cartridge where the toner replenishing container connecting hole 103 is located faces a toner cartridge assembling port of the printing apparatus after the toner cartridge is assembled into the printing apparatus. This means that when the toner in the toner cartridge is consumed, the toner cartridge assembly opening of the printing apparatus is opened, and the toner replenishing container connecting hole 103 can be exposed, so that the toner replenishing container can be connected to the toner replenishing container connecting hole 103 without taking the toner cartridge out of the printing apparatus, and the toner can be conveyed to the toner hopper 104 of the toner cartridge, and the operation is convenient.

Fig. 2 and 3 show a second embodiment of the invention. The cartridge 2 is provided with a rotating member (not shown in the drawings) as in a conventional cartridge. The rotating parts comprise related parts such as a photosensitive drum, a magnetic roller and the like, wherein the photosensitive drum and the magnetic roller rotate during the working process of the toner cartridge 2. A toner replenishing container attachment hole 302 (refer to fig. 3) is provided on the toner cartridge 2. The specific location of the toner supply container attachment hole 302 is shown in FIG. 3, or in FIG. 2, the hole in the toner hopper 207 is covered by the toner hopper cover 204. The position of the carbon powder replenishing container connecting hole 302 avoids the imaging laser irradiation range. That is, the imaging laser emitted by the laser generator of the laser printing apparatus will irradiate onto the photosensitive drum of the toner cartridge 2 within a certain irradiation range (usually, within a fan-shaped laser emission range), in order to avoid blocking the imaging laser, the toner replenishing container connecting hole 302 needs to be arranged outside the irradiation range of the imaging laser, and in the embodiment shown in fig. 2 and 3, the toner replenishing container connecting hole 302 is located adjacent to the end of the toner cartridge 2. The toner replenishing container connecting hole 302 is communicated with the toner hopper 207 of the toner cartridge.

The toner replenishing container attachment hole 302 includes a hole wall protruding from the toner hopper 207, and a universal shaft 206 is provided outside the hole wall on the side adjacent to the end of the toner cartridge 2. The multipurpose shaft 206 is a short shaft, and is parallel to the rotation axis of the rotating member of the cartridge 2. One end of the multipurpose shaft 206 is provided on the hole wall, and the other end is provided with a gear 205, and the gear 205 can rotate with the axis of the multipurpose shaft 206 as a rotation axis. In this embodiment, the gear 205 belongs to an external transmission mechanism, and is in transmission connection (in this embodiment, only the gears are in transmission connection with each other) with the rotating component (specifically, the transmission component of the rotating component, for example, the gear matched with the rotating component) of the cartridge 2 (in fig. 2, the gear 205 is driven by the rotating component of the cartridge 2) of the cartridge 2, that is, the rotating component of the cartridge 2 can drive the gear 205 to rotate. The gear 205 is arranged at a position close to the end part of the toner cartridge 2 with the gear transmission mechanism, so that the mechanism required for realizing the transmission connection is simple, the cost is reduced, and the reliability is improved.

The toner cartridge 2 is provided with a waste toner bin 202 for accommodating waste toner generated in the printing process of the toner cartridge 2. In the present embodiment, the toner cartridge 2 is also provided with a waste toner expansion bin 203. The waste toner expansion bin 203 communicates with the waste toner bin 202. The waste powder expansion bin 203 is also used for containing waste powder generated in the printing process of the toner cartridge 2. The waste toner expansion bin 203 is equivalent to the capacity of the waste toner bin expanded by the toner cartridge 2.

As can be seen in fig. 2, the cartridge 2 is also provided with a cover spigot 201. The cap insertion opening 201 is a blind hole having the same diameter as the toner replenishing container connection hole 302, i.e., the toner hopper cap 204 can be inserted into the cap insertion opening 201. The powder bin cover 204 is usually in a state of covering the toner replenishing container connecting hole 302, and when the toner needs to be replenished, the pulled-down powder bin cover 204 can be inserted into the cover inserting opening 201, so that the operator is prevented from taking out the power to find a place for the powder bin cover 204, and the operation is simplified. In addition, the disposable powder bin cover 204 is easily lost or damaged, which also causes inconvenience for plugging the toner replenishing container connecting hole 302 again, and thus the provision of the cover insertion opening 201 can avoid such inconvenience.

The cartridge 2 is also provided with a handle 208. The handle 208 is used for an operator to hold the cartridge 2. As can be seen from FIG. 3, a fixing member 301 is also provided on the side wall of the handle 208 as a toner replenishing container fixing structure. The specific shape of the fixing member 301 is a short axis. As can be seen in FIG. 3, the powder bin cover 204 is removed from its position in FIG. 2 and inserted into the cover receptacle 201, exposing the toner refill container attachment aperture 302.

Fig. 4 shows the structure of a second embodiment of the present invention. The embodiment shown in FIG. 4 is the same as the embodiment shown in FIG. 3, with the toner hopper cover inserted into the cover receptacle and the toner refill container attachment hole 402 exposed. Compared with the embodiment shown in fig. 2, the difference is that a waste powder bin cover 401 is arranged on the waste powder bin, and a fixing piece is not arranged on the side wall of the handle. When the waste powder in the waste powder bin and the waste powder expansion bin needs to be cleaned (poured out or sucked out), the waste powder bin sealing cover 401 can be opened, the waste powder outlet covered by the waste powder bin sealing cover 401 is exposed, and the waste powder is cleaned.

The technical solution of the present invention will be further described with reference to the usage of the toner cartridge 2 shown in fig. 5 and 6. Before proceeding with the corresponding explanation, it should be noted that the following descriptions of fig. 5 and 6, and the explanations relating to the up-down orientation, refer to the up-down orientation (i.e., up-down in the direction of gravity) in fig. 5 and 6. The direction of observation of the cartridge 1 shown in fig. 5 and 6 is the direction indicated by the arrow in fig. 2.

After the printing device 501 is placed on the horizontal working platform, the flip cover 502 above the printing device is opened in the gravity direction, the cartridge assembly opening 505 is exposed, the cartridge 2 is assembled from the upper right direction to the lower left direction in fig. 5, and the cartridge 2 is loaded into the printing device 501 through the cartridge assembly opening 505. Eventually the cartridge 2 reaches the position shown in fig. 5. The cartridge 2 is located at the final assembly position of the cartridge 2 in fig. 5. At this time, the surface of the cartridge (i.e., cartridge exposure surface) provided with the toner replenishing container attachment hole 302, the handle 208, and the cover insertion opening 201 shown in fig. 2 and 3 faces the cartridge mounting opening 505. Note that the cartridge exposure surface refers to a partial surface of the cartridge 2 externally visible through the cartridge mounting port 505, and the surface is not limited to a plane.

When the toner in the toner cartridge 2 is depleted or the toner cartridge 2 needs to be replenished with toner, the toner hopper cover 204 is first pulled out and the toner hopper cover 204 is inserted into the cover insertion opening 201. Then, the toner cartridge connecting hole 504 of the toner replenishing container 503 is inserted in alignment with the toner replenishing container connecting hole 302 (at this time, the toner replenishing container connecting hole 302 should be exposed), so that the toner replenishing container 503 reaches the position shown in fig. 6, the toner replenishing container 503 is communicated with the toner cartridge 207, the fixing parts (the fixing part 301 and the multipurpose shaft 206) of the two toner replenishing container fixing structures on the toner cartridge 2 are connected with the corresponding movable parts on the toner replenishing container 503 in a matching manner, and the toner cartridge 2 is stably connected with the toner replenishing container 503. Flip 502 is then closed.

In order to firmly set the toner replenishing container 503 on the toner cartridge 2, a movable member matching with the fixing member 301 is provided on the toner replenishing container 503. The stationary part 301 and the movable part belong to a stationary structure. The fixing structure stably connects the toner cartridge 2 with the toner replenishing container 503, so that toner can smoothly enter the toner hopper 207. The fixing structure in this embodiment adopts a pair of buckle structures. The buckle structure comprises a fixed part and a movable part. The fixed part is a part which does not change shape, and the movable part matched with the fixed part is a part which can clamp the fixed part through deformation so as to realize fixed connection. The movable member is similar to a clamping member such as an elastic folder, and is not described in detail herein since it belongs to the prior art. Two movable pieces are arranged on the toner replenishing container 503, one movable piece is matched with the fixed piece 301, and the other movable piece is matched with the multipurpose shaft 206. That is, the multi-purpose shaft 206 can also be used as a fixing member of the snap structure, thereby providing a more stable connection between the toner cartridge 2 and the toner replenishing container 503.

It should be further noted that the portion of the toner replenishing container connecting hole 302 protruding from the powder hopper 204 in the embodiment shown in fig. 2 has an inner radial dimension gradually decreasing from the upper opening toward the powder hopper. That is, the portion of the toner replenishing container connecting hole 302 protruding from the toner hopper 204 is an inverted cone shaped channel similar to a funnel, and of course, the corresponding toner hopper connecting hole 504 also has a matching inverted cone shaped outer profile. The inverted conical shape matching makes the toner replenishing container 503 easier to operate when connected with the toner cartridge 2, and particularly can reduce the requirement on the accuracy of operation alignment when the toner replenishing container 503 shields the toner replenishing container connecting hole 302 in operation. The inverted conical matching and the fixed connection structure can ensure that the connection between the carbon powder replenishing container connection hole 302 and the toner cartridge connection hole 504 is tighter, and the carbon powder is prevented from overflowing.

Next, the toner in the toner replenishment container 503 may fall into the toner hopper 207 under the force of gravity. In order to make the toner in the toner replenishing container 503 enter the toner hopper 207 more smoothly and thoroughly, a rotating shaft and a toner driving blade (not shown) are provided in the toner replenishing container 503. The toner driving blade is disposed on the rotating shaft and rotates with the rotation of the rotating shaft, so as to drive the toner in the toner replenishing container 503 to enter the toner hopper 207 through the toner hopper connecting hole 504. The implementation mode of the carbon powder driving blade belongs to the prior art, such as a helical fin and the like, and is not described herein again. In order to drive the rotating shaft to rotate, a gear is provided on the toner replenishing container 503, and the gear can be engaged with the gear 205 in fig. 2 and rotated by the gear 205. The arrangement of the external transmission mechanism of the toner cartridge 2 including the gear 205 enables the toner driving mechanism (the rotating shaft and the rotating blades) in the toner replenishing container 503 to be driven by the power received by the toner cartridge 2, and a power system is not required to be additionally arranged, so that the structure is simplified.

Therefore, the carbon powder replenishing container 503 is communicated with the powder bin 207, carbon powder is replenished into the powder bin 207, and the service life of the toner cartridge 2 is prolonged. The toner replenishment container 503 may be attached to the cartridge 2 until all of the toner therein is fed into the toner hopper 207.

As can be seen from the above description of fig. 5 and 6, the toner replenishing operation of the toner cartridge of the present invention does not require the toner cartridge to be taken out of the printing apparatus, which is very simple.

As the toner cartridge 2 can work for a longer time, more waste toner is generated along with the work, and can be accommodated by the space expanded by the waste toner expansion bin 203, and the waste toner bin 202 does not need to be cleaned frequently. Of course, the waste toner can be cleaned up through the waste toner discharge port as shown in fig. 4, if necessary.

It should be noted that the above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, but also to replace the above description with equivalent techniques. Therefore, all the equivalent changes made by the application of the specification and the contents shown in the drawings, or the direct or indirect application to other related technical fields are included in the scope covered by the present invention.
