Example four

Referring to fig. 4-9, to further illustrate the innovative contribution of the powder feeding box 1 in the first embodiment, the present embodiment provides a powder feeding box 1 for a toner cartridge, including: a case 11; the box body 11 comprises a bottom shell 110 and an upper cover 111, wherein the bottom shell 110 is detachably connected with the upper cover 111; the bottom shell 110 is internally provided with an inwards concave internal space 1100, and sufficient carbon powder is loaded in the internal space 1100 to meet the printing quantity requirement; the stirring frame 3 and the powder feeding roller 10 are arranged in the internal space 1100; the stirring frame 3 rotates to convey the carbon powder to the powder feeding roller 10.

In a modified example, the inside of the bottom case 110 is provided with a first convex cavity 1101 and a second convex cavity 1102; the first and second convex chambers 1101 and 1102 are used for loading carbon powder and communicate with the internal space 1100.

In one example of the improvement, a grasping groove 1103 is formed in the side surface of the bottom case 110; the grasping slot 1103 is flanked by a first relief cavity 1101 and a second relief cavity 1102.

In a modified example, the outer side of the upper cover 111 is provided with a finger slot 1110, and the finger slot 1110 is used for a finger of a user to grab.

In a modified example, the housing side surface of the bottom housing 110 is provided with a grasping groove 1103, the outer side surface of the upper cover 111 is provided with a finger fastening groove 1110, the housing side surface is adjacent to the outer side surface, and the distance between the grasping groove 1103 and the finger fastening groove 1110 is suitable for the palm to grasp the grasping groove 1103 and the fingers to fasten into the finger fastening groove 1110.

In a modified example, the finger slot 1110 includes a slot body 11100 and a plurality of arcuate slots 11101; the arc-shaped grooves 11101 are arranged on the inner wall of the groove body 11100 side by side, and the shape of the groove body of the arc-shaped grooves 11101 is matched with that of fingers.

In a modified example, the tank body 11100 has a rectangular inner tank shape.

In a modified example, the stirring frame 3 includes a first stirring frame 30 and a second stirring frame 31; the first stirring frame 30 and the second stirring frame 31 are arranged in parallel inside the bottom shell 110 at a predetermined distance.

In a modified example, a powder adding port 12 is arranged on one side of the powder feeding box 1, and the powder adding port 12 is used for adding carbon powder; the powder adding opening 12 extends out of the side wall of the powder sending box 1 by a set length.

In a modified example, the powder adding port 12 is provided with a powder adding cover 120, and the powder adding cover 120 is detachably connected with the powder adding port 12.

It should be noted that, the first convex cavity 1101 and the second convex cavity 1102 are both communicated with the inner space 1100 and located on two sides of the grasping groove 1103, such a structure arrangement can not only increase the space for loading carbon powder and enable the powder feeding box 1 to load more carbon powder at one time, but also form two groove body surfaces of the grasping groove 1103 on the outer sides of the first convex cavity 1101 and the second convex cavity 1102, so that a user can hold the bottom case 110 in the palm embedded groove body, and the grasping control is facilitated.

It should be further noted that the first convex cavity 1101 and the second convex cavity 1102 are both communicated with the inner space 1100, and are located at two sides of the grasping groove 1103 to form a component of the groove body of the grasping groove 1103, so that the technical effect of easily grasping the powder feeding box by adopting an integral structure matched with each other and expanding the powder feeding box is achieved, and the improvement is an important improvement for fully utilizing the space of the powder feeding box 1.

It should be noted that, since the space of the powder feeding box 1 is large and the powder feeding box is inconvenient to grasp, the improved example is provided with a finger-buckling groove 1110 on the outer side of the upper cover 111, so that the user can conveniently buckle the fingers into the grasping groove.

It should be noted that, the grasping groove 1103 and the finger buckling groove 1110 are designed to cooperate with each other, so that the distance between the grasping groove 1103 and the finger buckling groove 1110 is suitable for the palm to grasp the grasping groove 1103 and the fingers to buckle into the finger buckling groove 1110, which is convenient for the user to grasp even if the size of the powder feeding box 1 is large.
