Technical Field
[0001] This utility model relates to the field of printer technology, specifically to a toner cartridge structure that can reduce toner accumulation. Background Technology
[0002] A printer is one of the output devices of a computer, used to print the results of computer processing onto relevant media, and the toner cartridge is one of the most important components of a printer.
[0003] Currently, the side inclination of the powder feeding bin in existing powder bins is generally set at 45 degrees. This angle usually causes the powder to accumulate on the side of the powder feeding bin when the blade shaft scrapes the powder, which causes great trouble for users. Utility Model Content
[0004] The purpose of this invention is to provide a powder hopper structure that can reduce the accumulation of residual powder, thereby solving the problem mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder hopper structure that can reduce residual powder accumulation, comprising a powder hopper frame, a powder hopper provided on one side of the powder hopper frame, and an upper powder hopper provided on the side of the powder hopper frame away from the powder hopper, wherein the angle between the inclination of the side of the upper powder hopper away from the powder hopper and the horizontal plane is in the range of 60-70°, and this 60-70° inclination setting can reduce residual powder accumulation.
[0006] Preferably, both ends of the powder hopper frame surface are provided with shaft mounting holes, and the two sets of shaft mounting holes are used for the installation of the blade shaft to facilitate the scraping and feeding of toner.
[0007] Preferably, the powder hopper frame surface is provided with roller mounting holes above the shaft mounting holes, and the two sets of roller mounting holes are used to install the roller body.
[0008] Preferably, two support plates are integrally injection molded on the inner wall of the powder hopper frame surface. These support plates are used to provide stable support for the front of the powder hopper and the powder loading hopper.
[0009] Preferably, the bottom of the powder hopper frame is integrally injection molded with several sets of connecting pieces, which are used to provide stable support for the powder hopper and the back of the upper powder hopper.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model makes a special design to the powder loading chamber in the powder hopper structure, specifically setting the inclination of the side of the powder loading chamber away from the powder hopper to be 60-70° with the horizontal plane. This 60-70° inclination setting can reduce the accumulation of residual powder, thereby solving the problem in the prior art where the small inclination of the side of the powder loading chamber away from the powder hopper causes the carbon powder to accumulate on the side of the powder loading chamber when the blade shaft scrapes the carbon powder.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. In addition, the terms "first", "second", "third", "upper", "lower", "left", "right", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0017] This utility model provides a powder hopper structure that can reduce residual powder accumulation, as shown in the following figure. Figure 1 as well as Figure 2As shown, the device includes a powder hopper frame 1, a powder hopper 2 is provided on one side of the powder hopper frame 1, and an upper powder hopper 3 is provided on the side of the powder hopper frame 1 away from the powder hopper 2. The angle between the inclination of the side of the upper powder hopper 3 away from the powder hopper 2 and the horizontal plane is 60-70°. This 60-70° inclination setting can reduce the accumulation of residual powder.
[0018] This invention features a special design for the upper powder hopper 3 in the powder hopper structure. Specifically, the inclination of the upper powder hopper 3 away from the powder hopper 2 is set to an angle of 60-70° with the horizontal plane. This 60-70° inclination reduces residual powder accumulation, thereby solving the problem in the prior art where the small inclination of the upper powder hopper 3 away from the powder hopper 2 causes carbon powder to accumulate on the side of the upper powder hopper 3 when the blade shaft scrapes the carbon powder during feeding.
[0019] Furthermore, such as Figure 2 , Figure 3 as well as Figure 4 As shown, shaft mounting holes 4 are provided at both ends of the surface of the powder hopper frame 1. The two sets of shaft mounting holes 4 are used for the installation of the blade shaft to facilitate the scraping and feeding of toner. Roller mounting holes 6 are provided on the surface of the powder hopper frame 1 above the shaft mounting holes 4. The two sets of roller mounting holes 6 are used for the installation of the roller body. Two support plates 5 are integrally injection molded on the inner wall of the surface of the powder hopper frame 1. The support plates 5 are used for the stable support of the front of the powder hopper 2 and the upper powder hopper 3. Several sets of connecting plates 7 are integrally injection molded on the bottom of the powder hopper frame 1. The connecting plates 7 are used for the stable support of the back of the powder hopper 2 and the upper powder hopper 3.
[0020] Working principle: This utility model makes a special design to the powder loading chamber 3 in the powder hopper structure. Specifically, the inclination of the side of the powder loading chamber 3 away from the powder hopper 2 is set to an angle of 60-70° with the horizontal plane. This 60-70° inclination setting can reduce the accumulation of residual powder, thereby solving the problem in the prior art where the small inclination of the side of the powder loading chamber 3 away from the powder hopper 2 causes the blade shaft to scrape the powder and cause the carbon powder to accumulate on the side of the powder loading chamber 3.
