[0019] The utility model is described in detail below in combination with the drawings. In the detailed description of the utility model embodiments, for the convenience of description, the drawings showing the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the utility model protection herein. It should be noted that the drawings are simplified and all use non-precise proportions, only to facilitate, clearly assist in the purpose of describing the utility model embodiments. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features; the directions or position relationships indicated by the terms "positive", "negative", "bottom", "upper", "lower", "front", "rear", "left", "right" and the like are based on the directions or position relationships shown in the drawings, only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as limiting the utility model.

[0020] In the description of the utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the communication between two elements, or it can be wireless connection, or it can be wired connection. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0021] As shown in Figure 1 and Figure 2 The powder box of the embodiment includes a powder bin body 1, a space for containing carbon powder is formed in the powder bin body 1, the powder bin body 1 is provided with a powder outlet a, and the carbon powder can be transported outward through the powder outlet a. A magnetic roller 2 is arranged outside the powder outlet a, and the magnetic roller 2 is rotatably arranged outside the powder outlet a along its own axis. Gear side end covers 3 and conductive side end covers 4 are arranged on both sides of the powder bin body 1 respectively.

[0022] For ease of explanation, the space outside the powder outlet a of the powder hopper 1, where the magnetic roller 2 is located, is defined as the toner usage cavity. The toner usage cavity is connected to the inside of the powder hopper 1 via the powder outlet a, and toner enters the toner usage cavity after being output through the powder outlet a. The toner usage cavity includes a bottom wall 1a, a rear wall 1b, and two side walls 1c. The powder outlet a is located on the rear wall 1b, and the bottom wall 1a and the rear wall 1b are integrally connected. At both ends of the bottom wall 1a, there are first felt strip assembly grooves 1d and second felt strip assembly grooves 1e, respectively. The first and second felt strip assembly grooves are used to assemble the felt strips 5 that provide a sealing function. A sealing scraper 6 is also provided on the bottom wall 1a, with both ends of the sealing scraper 6 flush with both ends of the bottom wall 1a, covering the top of the first felt strip assembly grooves 1d and the second felt strip assembly grooves 1e.

[0023] like Figure 3 and Figure 5 As shown, the first felt strip assembly groove 1d includes a felt strip receiving portion A1 and an adhesive storage portion A2. The felt strip receiving portion A1 is used to mate with the felt strip 5. The lower half of the felt strip 5 is glued to the felt strip receiving portion A1 with adhesive, which also serves as a seal. The projection of the felt strip receiving portion A1 onto the plane of the bottom wall 1a is square.

[0024] The glue storage section A2 is used to store excess glue after application, preventing glue from accumulating in the felt strip receiving section A1 and causing gaps between the parts. The projection of the glue storage section A2 onto the plane of the bottom wall 1a is trapezoidal. The end of the glue storage section A2 connected to the felt strip receiving section A1 (front end) is small, and the end away from the felt strip receiving section A1 (rear end) is large, forming a trumpet shape.

[0025] In some embodiments, in order to facilitate the flow of glue into the glue storage section A2, the bottom wall of the felt strip receiving section A1 is inclined, with the top of the bottom wall being higher than the bottom wall, so that after the glue is applied, the glue can automatically flow into the glue storage section A2 along the bottom wall.

[0026] In some embodiments, the projection of the glue storage section A2 onto the plane of the bottom wall 1a is a right trapezoid. The side wall containing the sloping leg of the right trapezoid is the first groove wall s1, and the side wall containing the right leg of the right trapezoid is the second groove wall s2. The first groove wall s1 and the second groove wall s2 are opposite each other. The first groove wall s1 is located on the inner side, that is, it is farther away from the side wall 1c of the powder hopper than the second groove wall s2. The second groove wall s2 is located on the outer side, that is, it is closer to the side wall 1c than the first groove wall s1.

[0027] like Figure 4 and Figure 6 As shown, the structure of the second felt strip assembly groove 1e is the same as that of the first felt strip assembly groove 1d, and it also includes a felt strip receiving part A1 and an adhesive storage part A2. Please refer to the description of the structure of the first felt strip assembly groove.

[0028] like Figure 5and Figure 6 As shown, the two ends of the sealing scraper 6 cover the top of the felt strip assembly groove, separating the felt strip assembly groove from the toner usage chamber. This prevents glue from flowing into the toner usage chamber and affecting the normal use of the toner cartridge.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
