The second gear 5 is connected to one end of the stirring frame 22 passing through the shell 21, so that by driving the second gear 5 to rotate, the stirring frame 22 can be driven to rotate. The handle 6 is connected to the first shell 11, so that the powder box can be inserted into or pulled out of the image forming device through the handle.

[0056] The door assembly 3 includes a door 31 and an elastic member 32. The door 31 is movably disposed on the housing 21 so that the door 31 can move in a first direction. The door 31 is provided with an opening 311. The force-applying member 4 is disposed on the inner wall of the first housing 11. When the powder box 100 is installed on the image forming device, the first housing 11 is subjected to the force applied by the image forming device and moves in a second direction relative to the powder bin 2, so that the force-applying member 4 applies a force to the door 31 so that the door 31 moves in the first direction, and then the position of the opening 311 corresponds to the position of the powder outlet 211, thereby opening the powder outlet 211. The elastic member 32 is disposed in the box body 1, and is used to move the door 31 to the initial position to close the powder outlet 211. Of course, in some embodiments, the door 31 may not be provided with the opening 311. The door 31 can be discharged from the powder outlet 211 by sliding to the position where it does not cover the powder outlet 211, or the door 31 can be closed by sliding to the position where it covers the powder outlet 211.

[0057] Also refer to Figure 2 and Figure 3 As shown, the housing 21 is provided with a limit platform 212, the door 31 is also provided with a snap-fit ​​groove 313, the door assembly 3 also includes a limiter 33, the limiter 33 is connected to the door 31, and the limiter 33 can cooperate with the limit platform 212 to limit, and the snap-fit ​​groove 313 is used to cooperate with the second door on the image forming device to open the second door. In this embodiment, the door 31 includes an inclined portion, and the inclined portion is used to enable the door 31 to move along the first direction to open the powder outlet 211. Specifically, the inclined portion is set as an inclined groove 312, and the force member 4 is set as a column, and the column is penetrated in the inclined groove 312, so that the force member 4 can apply a force to the door 31 through the cooperation of the inclined groove 312 and the column. One end of the elastic member 32 is connected to the housing 21, and the other end of the elastic member 32 is connected to the inner wall of the first shell 11, and the length of the elastic member 32 extends along the second direction. Among them, the elastic member 32 can be a compression spring. The inclined groove 312 is in the form of an elongated hole, which may pass through the inner side and the outer side of the door 31 , or the elongated hole may not pass through the inner side of the door 31 .

[0058] In some embodiments, the door 31 includes a column, the force-applying member 4 includes an inclined portion, the inclined portion is provided with an inclined groove, and the inclined groove of the force-applying member 4 can cooperate with the column of the door 31 so that the force-applying member 4 can apply force to the door 31.

[0059] In actual application scenarios, the image forming device includes a main body and a door cover. After the powder box 100 is installed in the main body of the image forming device, the door cover is closed, and the first shell 11 will move toward the powder bin 2 along the second direction due to the force of the door cover. In the process of the first shell 11 moving toward the powder bin 2, the elastic member 32 is compressed, and the column will move in the inclined groove 312, thereby driving the bin door 31 to move along the first direction. When the bin door 31 moves to make the position of the opening 311 correspond to the position of the powder outlet 211, the powder outlet 211 is opened, and the developer stored in the shell 21 can be output through the powder outlet 211, the opening 311 and the notch 121, and supplied to the image forming device. When the door cover of the image forming device is opened, the pressure of the door cover on the box body 1 can be released, and the box body 1 moves away from the powder bin 2 in the second direction (that is, moves in the opposite direction of the powder box installation direction) under the elastic restoring force of the elastic member 32, and the column moves in the opposite direction in the inclined groove 312, thereby driving the bin door 31 to move in the first direction, so that the opening 311 of the bin door 31 is offset from the powder outlet 211, and the powder outlet 211 is closed.

[0060] In this embodiment, when the door cover of the image forming device is closed, the door of the powder box can be opened and the door remains in the open state. When the door cover is opened, under the action of the restoring force of the elastic member, the door moves in the opposite direction of the installation direction of the powder box to close the powder outlet. That is, the powder box can automatically open the powder outlet during the installation process without the need for manual opening of the powder outlet, thereby improving efficiency.

[0061] Embodiment 2

[0062] The structure of the powder box 100 of this embodiment is basically the same as that of the powder box 100 of the first embodiment, and the difference is that the method of driving the compartment door 31 to move in this embodiment is different from that in the first embodiment.

[0063] Reference Figure 4 and Figure 5 As shown, the door 31 includes a serrated portion 314, and the door assembly 3 also includes a rack 34 and a first gear 35. The rack 34 is movably disposed on the powder bin 2, and the first gear 35 is disposed on the powder bin 2, and the first gear 35 is meshed with the rack 34 and the serrated portion 314 respectively. The elastic member 32 is disposed in the mounting cavity of the box body 1, and one end of the elastic member 32 is connected to the rack 34, and the other end of the elastic member 32 is connected to the powder bin 2, and the length of the elastic member 32 extends along the first direction. Of course, the elastic member 32 can also be exposed outside the box body, and one end of the elastic member 32 is connected to the rack 34, and the other end of the elastic member 32 is connected to the side wall of the powder bin 2.

[0064] Reference Figure 6 and Figure 7 As shown, the force applying member 4 has an inclined portion, which is used to enable the bin door 31 to move along the first direction to open the powder outlet 211. Further, the inclined portion is configured as a first inclined surface 41, which is used to apply a force to the rack 34.

[0065] Reference Figure 8 As shown, in an actual application scenario, the image forming device includes a main body and a door cover. After the powder box 100 is installed in the main body of the image forming device, the door cover is closed, and the first shell 11 will move toward the powder bin 2 along the second direction due to the force of the door cover. In the process of the first shell 11 moving toward the powder bin 2, the first inclined surface 41 will apply a force to the rack 34, so that the rack 34 moves along the first direction. During the movement, the rack 34 will compress the elastic member 32 and drive the first gear 35 to rotate, thereby driving the bin door 31 meshing with the first gear 35 to move in the first direction through the rotation of the first gear 35. When the bin door 31 moves to make the position of the opening 311 correspond to the position of the powder outlet 211, the powder outlet 211 is opened, and the developer stored in the shell 21 can be output through the powder outlet 211, the opening 311 and the notch 121, and supplied to the image forming device. When the door cover of the image forming device is opened, the pressure of the door cover on the box body 1 can be released, and the first inclined surface 41 will no longer apply a force to the rack 34. At this time, the rack 34 moves along the first direction under the elastic restoring force of the elastic member 32, thereby driving the first gear 35 to rotate in the opposite direction, and then driving the warehouse door 31 to move along the first direction, so that the position of the opening 311 of the warehouse door 31 is offset from the position of the powder outlet 211, and then the powder outlet 211 is closed.

[0066] In this embodiment, when the door cover of the image forming device is closed, the door of the powder box can be opened. When the door cover is opened, under the action of the restoring force of the elastic member, the door moves in the opposite direction of the installation direction of the powder box to close the powder outlet. That is, the powder box can automatically open the powder outlet during the installation process without the need for manual opening of the powder outlet, thereby improving efficiency.

[0067] Embodiment 3

[0068] The structure of the powder box 100 of this embodiment is basically the same as that of the powder box 100 of the first embodiment, and the difference is that the method of driving the compartment door 31 to move in this embodiment is different from that in the first embodiment.

[0069] Reference Fig. 9 and Fig.10As shown, the force-applying member 4 is movably disposed in the box body 1, and the force-applying member 4 is connected to the door 31, and the force-applying member 4 partially passes through the box body 1. One end of the elastic member 32 is connected to the door 31, and the other end of the elastic member 32 is connected to the second shell 12 (the other end of the elastic member 32 can also be connected to the first shell 11 or the powder bin), and the length of the elastic member 32 extends along the first direction. During the installation of the powder box 100 to the image forming device, the force-applying member 4 is subjected to the force applied by the image forming device and moves along the first direction to drive the door 31 to move along the first direction, thereby opening the powder outlet 211. The elastic member 32 is used to move the door 31 to the initial position to close the powder outlet 211.

[0070] Specifically, the box body 1 is provided with a through hole 13, the force-applying member 4 includes a force-bearing portion 42 and a connecting portion 43, the connecting portion 43 is sleeved on the powder bin 2 and connected to the bin door 31, the force-bearing portion 42 is connected to the connecting portion 43 and passes through the upper surface of the box body 1 through the through hole 13, and the force-bearing portion 42 has an inclined portion, which is used to enable the bin door 31 to move along the first direction to open the powder outlet 211. In this embodiment, the inclined portion is set as a second inclined surface 421.

[0071] Further, the powder box 100 further includes a push block 7, which is movably connected to the first housing 11, and the push block 7 can cooperate with the force receiving portion 42, so that the image forming device can apply force to the push block 7 and cause the push block 7 to move, thereby driving the force applying member 4 to move, so as to drive the bin door 31 to move and open the powder outlet 211. Fig.11 As shown, in an actual application scenario, the image forming device includes a main body and a door cover. After the powder box 100 is installed in the main body of the image forming device, the door cover is closed, and the door cover 200 applies a force to the second inclined surface 421 of the force-bearing portion 42 through the push block 7, so that the force-applying member 4 moves along the first direction, thereby driving the bin door 31 to move along the first direction and compressing the elastic member 32 at the same time. When the bin door 31 moves to make the position of the opening 311 correspond to the position of the powder outlet 211, the powder outlet 211 is opened, and the developer stored in the housing 21 can be output through the powder outlet 211, the opening 311 and the notch 121, and supplied to the image forming device. When the door cover of the image forming device is opened, the squeezing of the door cover 200 on the push block 7 can be released, the force-applying member 4 is no longer subjected to the force of the push block 7, and the bin door 31 moves along the first direction under the elastic restoring force of the elastic member 32, so that the position of the opening 311 of the bin door 31 is offset from the position of the powder outlet 211, thereby closing the powder outlet 211.

[0072] In the process of installing the powder box in this embodiment, a force is applied to the force applying member through the door cover of the image forming device, so that the powder outlet of the powder box is automatically opened without manual opening of the powder outlet, thereby improving efficiency.

[0073] Embodiment 4

When the bin door 31 moves to make the position of the opening 311 correspond to the position of the powder outlet 211, the powder outlet 211 is opened, and the developer in the housing 21 can be output through the powder outlet 211, the opening 311 and the notch 121, and supplied to the image forming device. When the door cover of the image forming device is opened, the squeezing of the force-applying member 4 can be released, and the force-applying member 4 is no longer subjected to the force of the image forming device. The compartment door 31 moves in the first direction under the elastic restoring force of the elastic member 32, and the opening position of the compartment door 31 is offset from the position of the powder outlet 211, thereby closing the powder outlet 211. In this process, the image forming device releases the squeezing of the third inclined surface 422 of the force-applying member 4.

[0079] In the process of installing the powder box in this embodiment, a force is applied to the force applying member through the side wall of the toner cartridge in the image forming device, so that the powder outlet of the powder box is automatically opened without manual opening of the powder outlet, thereby improving efficiency.
