The above transmission structure further comprises a rotation transferring component which is installed inside the image processing system wherein the driving rod of the sealing component drives the sealing component to move axially, which opens the toner discharge opening. The rotation transferring component comprises a circular wall and a transmission shaft which is co-axial with the circular wall. The circular wall has a connection opening which extends from the surrounding of the circular wall.
When the rotation transferring component is connected with the toner cartridge, the transmission shaft drives the driving rod of the sealing component to move axially and open the toner discharge opening.
In the toner cartridge of the invention, the outline of the side surface of the driving projection is triangular or arc shaped.
In the toner cartridge of the invention, the connection component comprises a circle-shaped base and several elastic linking arms which extend from the circle of the circle-shaped base along the axial direction; the hook-shaped projections are formed at the end of the elastic linking arms; the base has an opening which allows the driving rod of the sealing component to pass through.

In the toner cartridge of the invention, the end of the driving rod of the sealing component that cooperates with a transmission shaft has a pit, and the transmission shaft is conically shaped.
In the toner cartridge of the invention, the connection component, the transmission component, and the sealing component are independent and each performs its own function. This structure ensures operating stability and reduces the material quality requirement allowing more environmentally friendly materials to be used in the invention. The transmission component and the connection component can axially move relative to the connection component compartment 22; this structure makes the rotation of the operation handle easier and more convenient. The container component of the toner cartridge and the rotation transferring component of the developer are fixed along the axial direction; this helps steady rotation.
The invention is further illustrated by the combination of the drawings and the embodiments below.
The end of the rotary container body 1 is provided with a toner discharge port 2. The toner discharge port 2 comprises a cylinder 20. An end of the cylinder 20 is connected with the rotary container body 1 and the other end of the cylinder is provided with a cap. The cylinder 20 has a toner discharge opening 201, toner can flow to the cylinder 20 from the rotary container body 1, the toner discharge opening 201 discharges the toner to the toner accepting component of the image processing system. There can be more than one toner discharge opening 201. The toner discharge opening 201 can be a strip that extends from the cylinder 20. The cap is provided with a connection component compartment 22 which extends outwards from the cap. The connection component compartment 22 is used to cooperate with the connection component 5.
The toner discharge opening 201 of the toner discharge port 2 opens when the toner cartridge is installed on the developer; when it is not being used, it is sealed. Therefore, the toner discharge port 2 is provided with a sealing component 3. The sealing component 3 is installed inside the cylinder 20; it opens or closes the toner discharge opening 201 through its axial movement. The sealing component 3 comprises a ring 30 and a sleeve 31 which is coaxial to the ring 30. The sleeve 31 and the ring 30 are linked through a ridge-shaped structure. Axial movement of the ring 30 drives the sealing component 3 to open or close the toner discharge opening 201. The sealing component is driven by the driving rod 4. The driving rod 4 of the sealing component is rod-shaped. In this embodiment, it is a rounded rod. One end of the driving rod 4 passes through the cylinder 20 and it is then connected with the sealing component 3; and the cap has an opening for the driving rod 4 to pass through. In this embodiment, the driving rod 4 passes through the sleeve 31 and then connects with the sealing component 3. The sleeve 31 is provided with two opposite openings 311; the end of the driving rod 4 of the sealing component is provided with two elastic latches 41; and the elastic latches 41 are latched in the openings 311.
In this embodiment, the toner cartridge comprises a connection component 5. The connection component 5 is slide-connected with the connection component compartment 22 of the toner discharge port 2. The connection component compartment 22 rotates with the connection component 5, and it drives the container body 1 to rotate. The connection component 5 comprises a circle-shaped base 50 and several elastic linking arms 52 which are formed by the extension from the circle 50 of the circle-shaped base 50 along the axial direction. The end of each elastic linking arm 52 has a hook-shaped projection 51. The base 50 has an opening which allows the driving rod 4 of the sealing component to pass through. The side surface 511 of each hook-shaped projection 51 of the connection component 5 is sloped or arc-shaped, and therefore when it couples with the rotation transferring component 7, the connection component 5 only has a connecting function, but does not directly burden the driving force from the rotation transferring component 7. The inner wall of the connection component compartment 22 is provided with axially extending ridges 221 and the external periphery of the base 50 is provided with the sliding grooves 501 which cooperate with the ridges 221. There can be several ridges 221 and several corresponding grooves 501. When they are combined, the ridges 221 are inserted into the grooves 501, and thus the connection component 5 and the connection component compartment 22 restrict each other and the connection component compartment 22 rotates with the connection component 5.
In this embodiment, the toner cartridge further comprises a transmission component 6 which is used to transmit the driving force from the rotation transferring component 7 to the toner cartridge. The transmission component 6 is slide-connected with the connection component 5. The connection component 5 rotates with the transmission component 6. The base 50 of the connection component 5 has a positioning post 53 which extends axially from the base portion 50. See
In the original state of the toner cartridge, i.e., before the toner cartridge is installed on the developer, the ring 30 of the sealing component 3 seals the toner discharge opening 201 of the toner discharge port 2, and the connection component 5 and the transmission component 6 cover the driving rod 4 of the sealing component. Due to the space restriction at the end of the driving rod 4 of the sealing component, the connection component 5 and the transmission component 6 are restricted to the end of the toner discharge port 2.
The transmission structure of the toner cartridge is the rotation transferring component 7. The rotation transferring component 7 is installed inside the image processing system and it comprises a circular wall 70 and a transmission shaft 71 which is coaxial with the circular wall 70. The circular wall 70 and the transmission shaft can be linked through a ribbed plate or an end circle structure. The circular wall 70 has a connection opening 701 which extends from the surrounding of the circular wall 70. There can be one or more connection openings 701. Preferably, there are two connection openings 701, which help the transmission structure to bear the force evenly.
When the rotation transferring component 7 is linked with the toner cartridge, i.e., the toner cartridge is installed on the developer, the transmission shaft 71 of the transmission component pushes the driving rod 4 of the sealing component, the driving rod 4 pushes the sealing component 3 to move axially relative to the toner discharge port 2 to open the toner discharge opening 201. The hook-shaped projection 51 of the connection component 5 and the transmission projection 61 of the transmission component 6 are coupled with the connection opening 701. That is, both the hook-shaped projection 51 and the transmission projection 61 are inside the connection opening 701. When the rotation transferring component 7 rotates, the end of the connection opening 701 pushes the transmission projection 61, the transmission component 6 receives the driving force from the rotation transferring component 7, and the transmission component 6 rotates with the rotation transferring component 7. Because the side surface 511 of the connection projection 51 of the connection component 5 is sloped or arc-shaped, the guiding function of the side surface makes the elastic connection arm 52 to deform and contract, and thus the connection component 5 does not directly bear the driving force from the rotation transferring component 7. To make the coordination between the transmission shaft 71 and the driving rod 4 of the sealing component easier, the end of the driving rod 4 of the sealing component where it cooperates with the transmission shaft 71 is provided with a pit and the end of the transmission shaft 71 is designed to be conical.
As shown in
In the transmission structure of the toner cartridge of the invention, the connection, the transmission, and the sealing components are independent and each performs its function; this structure provides operating stability, reduces requirements on the materials used, and allows the use of more environmentally friendly materials. Because the transmission component and the connection component can move axially relative to the toner discharge port 2, it is more convenient to rotate the operation handle.
The above description illustrates the invention by combining the drawings and the embodiments. However, the invention is not limited to these embodiments. The above embodiments are illustrative only, but do not limit the invention. Persons skilled in the art will recognize many variations by following the invention.
