Detailed Description

The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:

referring to fig. 1 and 2, a toner cartridge 10 according to embodiment 1 of the present invention includes a housing 20, a powder poking rod 30, and a vibration device 40.

The housing 20 has a cylindrical portion 21 and a transmission portion 25. The cylindrical part 21 is used for containing carbon powder, the cylindrical part 21 is provided with a hollow pipe body 22 and a sealing cover 23, the sealing cover 23 is fixedly arranged at one end of the pipe body 22, the inner side surface of the sealing cover 23 is provided with a convex ring 24, and the transmission part 25 is rotatably arranged at the other end of the pipe body 22. In other embodiments, the cap 23 and the tube 22 can be integrally formed.

The powder poking rod 30 is arranged in the cylinder part 21 of the shell 20 and is provided with a rod part 31, and one end of the rod part 31 is connected with the transmission part 25 of the shell 20, so that the powder poking rod 30 can be driven by the transmission part 25 of the shell 20 to rotate in the cylinder part 21 of the shell 20. The powder poking rod 30 further comprises a spoon part 32 arranged at one end of the rod part 31 and a disc part 33 arranged at the other end of the rod part 31, the spoon part 32 is used for conveying carbon powder from the cylinder part 21 to the transmission part 25, the disc part 33 is rotatably accommodated in the convex ring 24 of the sealing cover 23 of the shell 20, the disc part 33 is provided with an outer arc part 34 and a plurality of spokes 35, and the spokes 35 connect the outer arc part 34 with the rod part 31. In addition, the powder stirring rod 30 further has a plurality of stirring rods 36 disposed on one side of the rod 31, and a stirring plate 37 disposed on the other side of the rod 31, when the powder stirring rod 30 rotates, the stirring rods 36 are used for stirring the carbon powder, and the stirring plate 37 is used for stirring the carbon powder toward the spoon part 32.

The vibration device 40 has a notch 41 and a resilient portion 42, in this embodiment, the notch 41 is disposed on the convex ring 24 of the housing 20, the resilient portion 42 has a resilient arm 43 disposed on the outer arc portion 34 of the disk portion 33 of the powder-stirring rod 30, and a protrusion 44 is disposed at the end of the resilient arm 43, such that the resilient portion 42 rotates with the powder-stirring rod 30 relative to the cylinder portion 21 of the housing 20, wherein the outer edge of the resilient arm 43 and the outer edge of the outer arc portion 34 form a circumference, and the protrusion 44 extends radially outward from the circumference.

As can be seen from the above structure, when the toner cartridge 10 is inserted into an electronic imaging device (such as a photocopier or a printer), the transmission portion 25 of the housing 20 is driven by a driving member (not shown) of the electronic imaging device to rotate, and the powder-stirring rod 30 is driven by the transmission portion 25 of the housing 20 to rotate relative to the cylinder portion 21 of the housing 20. Then, during the rotation of the powder-stirring rod 30, the elastic portion 42 rotates along with the disk portion 33 of the powder-stirring rod 30, if the protrusion 44 does not correspond to the notch 41, as shown in fig. 3, the elastic arm 43 is pressed by the inner ring surface of the convex ring 24 to accumulate the elastic restoring force, once the protrusion 44 corresponds to the notch 41, as shown in fig. 4, the protrusion 44 extends into the notch 41 by the elastic restoring force of the elastic arm 43, the elastic arm 43 impacts the inner ring 24 from inside to outside to vibrate the cylinder 21, and the carbon powder adhered to the inner wall of the cylinder 21 can be shaken off by the intermittent vibration and then discharged out of the housing 10, thereby effectively reducing the residual powder amount of the carbon powder. In addition, when the protrusion 44 extends into the notch 41, the position of the powder-stirring rod 30 can be located, for example, when assembling the toner cartridge, the powder-stirring rod 30 can be fixed at a predetermined angle by using the structure, so that the angle of the powder-stirring rod 30 can be matched with the transmission part 25, and the intermittent vibration can be generated when the transmission part 25 drives the powder-stirring rod 30 to rotate. The number of the notches 41 can be increased as required, and in the present embodiment, there are two notches 41.

Referring to FIG. 5, the toner cartridge of embodiment 2 of the present invention is substantially the same in main structure as the toner cartridge of embodiment 1, but has some differences in structure. For example, the protruding ring 52 of the cap 51 is arc-shaped, the disc portion 62 of the powder-stirring rod 60 has a circular ring portion 63 and a plurality of spokes 64, the spokes 64 connect the circular ring portion 63 and the rod portion 61 together, and the position of the notch 41 and the elastic portion 42 of the vibration device 40 is just opposite to that of the aforementioned embodiment 1, that is, the notch 41 is disposed on the circular ring portion 63 of the disc portion 62 of the powder-stirring rod 60, the elastic arm 43 of the elastic portion 42 is disposed at one end of the protruding ring 52 of the cap 51, and the protrusion 44 of the elastic portion 42 is disposed at the end of the elastic arm 43. Therefore, when the powder stirring rod 60 starts to rotate, the notch 41 rotates along with the powder stirring rod 60, when the notch 41 and the lug 44 are staggered, as shown in fig. 6, the lug 44 is pushed outwards by the outer annular surface of the annular part 63, so that the elastic arm 43 accumulates elastic restoring force, once the notch 41 corresponds to the lug 44, as shown in fig. 7, the lug 44 extends into the notch 41 by the elastic restoring force of the elastic arm 43, and simultaneously the elastic arm 43 impacts the annular part 63 from outside to inside to vibrate the powder stirring rod 60 and the barrel part 21, so that the cyclic operation can also promote the carbon powder to shake off by intermittent vibration, thereby achieving the effect of reducing the residual powder amount.

Referring to FIG. 8, the structure of the toner cartridge of embodiment 3 of the present invention is the same as that of embodiment 1, but the structure of the powder poking rod 70 and the vibrating device 80 are different. In detail, the disc portion 72 of the powder pulling rod 70 has a radial rod 73, the bottom end of the radial rod 73 is connected with the rod portion 71, the notch 81 of the vibration device 80 is disposed on the convex ring 24, the elastic portion 82 of the vibration device 80 has a propping block 83 and an elastic member 84, the propping block 83 is movably sleeved on the top end of the radial rod 73, and the elastic member 84 is sleeved on the radial rod 73 and props against the rod portion 71 and the propping block 83 of the powder pulling rod 70 with two ends thereof respectively. Therefore, when the powder pulling rod 70 starts to rotate, the elastic part 82 rotates along with the powder pulling rod 70, when the notch 81 and the abutting block 83 are staggered, as shown in fig. 9, the abutting block 83 is pressed by the inner ring surface of the convex ring 24, so that the abutting block 83 further compresses the elastic member 84 to accumulate the elastic restoring force of the elastic member 84, once the abutting block 83 corresponds to the notch 81, as shown in fig. 10, the abutting block 83 partially extends into the notch 81 by the elastic restoring force of the elastic member 84, and simultaneously the abutting block 83 impacts the convex ring 24 from inside to outside to vibrate the cylinder part 21, so that the cyclic operation can lead the carbon powder to be vibrated intermittently, thereby achieving the effect of reducing the residual powder amount.

Based on the spirit of the present invention, the structure of the toner cartridge can be further modified, for example, the structure of the vibration device can be modified, as long as the barrel part can intermittently generate vibration along with the rotation of the powder poking rod, the barrel part 21 of the housing 20 can be provided with a groove capable of accommodating the disk part 33 instead of the convex ring 24, and the

notches

41 and 81 can be positioned on the inner wall surface of the groove; in addition, the disk portions 33, 62 may be provided without the outer arc portion 34, the annular ring portion 63 and the spokes 35, 64, but may be presented in a solid structure as long as they are compatible with the torus 24.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
