Background
The image forming device of a general printer is composed of main parts such as a carbon powder bin, a waste powder bin, a photosensitive element, a charging wheel, a magnetic wheel, a powder discharging blade cleaning blade and the like, and the main parts are combined together to form an image forming device which is installed inside the printer and used for developing and imaging. Image forming apparatuses can be classified into horizontal and vertical exposures depending on the position of a laser light emitting source relative to a photosensitive drum, and thus the design of the image forming apparatuses is also classified into two types: model ㄈ and two-wing model. An ㄈ model image forming apparatus, wherein a laser light source is exposed to light from ㄈ font intermediate level. The laser source of the two-wing image forming apparatus is vertically exposed from top to bottom between the two wings.
The conventional image forming apparatuses, such as those provided by major manufacturers of HP company, Canon company, Samsung company, etc., are designed to be disposable, that is, the original toner in the image forming apparatus is directly discarded after being used up, and a user is required to buy a completely new image forming apparatus again.
The discarded image forming apparatuses are recycled by some companies in the industry, and are sold after being refilled with carbon powder, so that compatible recycling is realized, and recycling and filling can be repeated for 3-4 times generally. Since the image forming apparatus (also called cartridge, toner cartridge, etc.) is complicated in the disassembling and assembling process, and it is difficult for a general user to complete the work, the industry designs a toner replenishing hole and a toner cleaning hole in the toner hopper and the waste toner hopper to improve the problem, so as to facilitate the refilling of these recycling manufacturers and the filling by the user. However, such powder replenishing and cleaning is inconvenient for users, such as sprinkling and inhaling into their bodies, and causes damage to the environment and the body of the user.
To improve this problem, many companies often choose to design large-capacity image forming apparatuses, reduce the replacement frequency of the image forming apparatuses, reduce pollution, and reduce cost, for example, chinese patent application No. 201720087889.0, published 2017, 8.8.8.a high-performance toner cartridge matching structure that changes the structure of a toner cartridge and increases the amount of toner filled, thereby achieving or exceeding the original printing amount. The utility model discloses a powder storehouse bottom plate of being connected with carbon dust box seat, the surfacing of powder storehouse bottom plate be provided with large capacity face lid on the powder storehouse bottom plate, large capacity face lid is the outside convex arch casing of cambered surface, the coverage of large capacity face lid is less than the area of powder storehouse bottom plate. This utility model is suitable for a printing consumables image forming device product regeneration field. However, the increase in the capacity of the image forming apparatus brings about a new problem that a large amount of internal space of the printer is required, and therefore, the structure of the printer itself needs to be modified, and it is obviously not desirable for users to purchase new machines at an increased cost.
