Preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Fig. 1-Fig. 5 shows the specific embodiment of the present utility model: processing box, comprises bottom bin 4, and one side of bottom bin 4 is provided with powder feeding gear 2, and bottom bin 4 is provided with powder feeding shaft 7, on the powder feeding shaft 7 The powder feeding blade 8 is set, the powder feeding gear 2 is connected with the powder feeding shaft 7, and the powder feeding gear 2 is driven by an external drive gear 1 to rotate. The bottom bin 4 is provided with a powder outlet, and a switch cover is provided at the powder outlet 6. The inside of the switch cover 6 is provided with a powder outlet sponge 5. This switch cover is a multi-functional component with a normally closed self-locking function and an automatic locking when rotating to open and rotate to close.

The bottom bin 4 includes a toner cartridge switch cover opening part 41 arranged at the powder outlet on the bin body 47; and a handle 42 provided on the bin body 47, and the two ends of the handle 42 are provided with a limit guide part 44 and a positioning guide part 46; A switch cover guide 43 is provided at the powder outlet, and an installation guide 45 is also provided on the bottom bin 4 .

The drum switch cover opening part is made up of a group of raised drum switch cover opening part 413, the drum switch cover opening part 414, the drum switch cover closing part 411 and the drum switch cover closing part 412; the bottom compartment 4 has a switch cover guide part 43 , The switch cover guide 43 contains 2 guide rail guides: the guide rail guide has a switch cover normally closed lock hook edge 431, a switch cover main rail 432, the switch cover takes out the closing guide rail 433, and the switch cover takes out the unlocking guide rail 434.

The switch cover 6 is composed of a switch cover opening part 61, a switch cover locking part 62, a switch cover locking mechanism 63 and a switch cover body part 64; the switch cover 6 is composed of a switch cover opening part 61, two sets of switch cover locking parts 62, two The switch cover locking mechanism 63 and the switch cover body part 64 are composed; wherein the switch cover locking part 62 includes an elastic arm 621, a lock hook edge 622 and a guide part 623; wherein the switch cover locking mechanism 63 includes an elastic arm 631 for locking Unhook the guide column 632 and the locking hook 633 .

Transmission gear 1, powder feeding gear 2, cover 3, bottom chamber 4, switch cover 6 and powder feeding shaft 7 are obtained by injection molding; transmission gear 1 and powder feeding gear 2 are preferably POM materials; cover 3, bottom chamber 4, switch The cover 6 and the powder feeding shaft 7 are preferably made of HIPS and ABS materials; the powder outlet sponge 5 and the powder feeding blade 8 are punched from sealing sponge and PC sheet respectively;

The process cartridge of the present invention is installed in the toner cartridge assembly (with reference to Figure 29a & b of the disclosed technology CN107077086A): the toner cartridge assembly contains the toner cartridge powder bin switch cover 237 (which includes outer frame edges 237a and 237b), unscrew the limit portion of the switch cover of the process cartridge 232 and a restricting portion 263 that rotates and slides to close the switch cover of the process cartridge.

In the present invention, when a new process cartridge is installed to the toner drum assembly of the imaging device (refer to Figure 29a & b of the disclosed technology CN107077086A), the toner drum switch cover opening part 413 of the process cartridge, the toner drum switch cover opening part 414, and the toner drum switch cover closing part 411 And the toner cartridge switch cover closing part 412 can be stuck on the both sides of the toner cartridge powder storehouse switch cover 237, and now the toner cartridge toner storehouse switch cover 237 will rotate with the bottom storehouse of the process box; rotate the process box, and the toner cartridge switch cover of the process box is opened Part 41 will open the toner cartridge powder storehouse switch cover 237 of the toner cartridge assembly, and the switch cover opening part 61 of the switch cover 6 of the process box is restricted and blocked by the restriction part 232 of the switch cover of the toner cartridge assembly unscrewed at the same time, at this moment, the switch cover 6 The lock hook side 622 of the switch cover locking part 62 is deformed by the rotation force of the elastic arm 621 and is released from the switch cover normally closed lock hook side 431 on the bottom compartment 4 to be unlocked, and the powder outlet of the process box continues to rotate to the toner cartridge powder compartment of the toner cartridge assembly. The position before the switch cover 237 is opened, the switch cover 6 of the process box will slide relatively along the switch cover main rail 432 of the process box at the same time. Take out the unlocking guide rail 434 to rise elastically so that the upper locking hook 633 of the switch cover 6 is locked on the locking position of the restricting part 263 of the switch cover of the toner cartridge assembly, which rotates and slides to close the process box. At this time, the transmission gear drives the powder feeding gear to rotate and feed powder The blade replenishes the developer in the process box and sends it into the powder compartment of the toner drum assembly; when the developer is replenished and the process box is taken out, the process box needs to be rotated in reverse, and at this time the locking hook 633 of the switch cover 6 of the process box is locked on the toner drum The rotation and sliding of the assembly closes the limit part 263 of the switch cover of the process box and is fixed at the locked position; when the process box continues to be rotated, the locking and unlocking guide post 632 of the switch cover 6 slides along the switch cover of the bottom compartment 4 to take out the closing guide rail 433 The switch cover of the bottom compartment 4 is taken out of the position of the unlocking guide rail 434, and the elastic arm 631 deforms and bends downward, thereby causing the locking hook 633 of the switch cover 6 to break away from the locking position of the restricting part 263 of the switch cover of the process cartridge closed by the rotation and sliding of the toner cartridge assembly. At the same time, when the guide part 623 of the switch cover locking part 62 of the switch cover 6 will slide out from the switch cover main rail 432 of the bottom compartment 4, the lock hook side 622 of the switch cover will be locked on the switch cover normally closed lock hook of the bottom compartment 4 On the edge 431; now the switch cover 6 of the process box can be closed and locked on the process box, and the process box is rotated, and the toner cartridge switch cover opener 41 of the process box can open the toner cartridge powder storehouse switch cover 237 of the toner cartridge assembly.

In the implementation of the switch cover of the present invention, the implementation with its own elastic normally closed power can also be adopted, and the two elastic arms 621 and 631 of the switch cover 6 can be changed into two elastic parts such as spring/rubber band/elastic tension damping part, Hook the elastic part on the side of the normally closed lock hook of the switch part, so as to realize the self-elastic power closing of the switch cover.

The above is only the preferred embodiment of the utility model, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the utility model, some deformations and improvements can also be made. Belong to the protection scope of the utility model.
