[0006] A toner cartridge protective cover includes an upper plate, a lower plate, and side plates. The upper plate has a hook at its right end for hooking the raised part of the toner cartridge. The left end of the upper plate is connected to the upper end of the side plate, and the left end of the lower plate is connected to the side plate. The front and rear ends of the upper plate extend downwards to form an upper front guard plate and an upper rear guard plate, respectively. The front and rear ends of the lower plate extend upwards to form a lower front guard plate and a lower rear guard plate, respectively. The space formed between the upper and lower plates matches the space at the corresponding end of the toner cartridge. The upper plate, lower plate, and side plates are all made of plastic material.

[0007] The following improvements can be further implemented to solve the problem of this utility model:

[0008] Further improvements include extending a side front guard plate from the front end of the upper plate towards the right end of the upper plate.

[0009] Further improvements include extending a side rear guard plate from the rear end of the upper plate towards the right end of the upper plate.

[0013] Further improvements include making the wall of the photosensitive drum placement slot curved.

[0014] The toner cartridge of this utility model can adopt the following technical solution:

[0015] A toner cartridge includes a main frame, a housing, a photosensitive drum, and a waste toner container. The main frame is located inside the housing, and the photosensitive drum is mounted on the main frame. The top surface of the housing has a laser projection port, and the housing has a raised portion. It also includes a toner cartridge protective cover, which includes an upper plate, a lower plate, and side plates. The right end of the upper plate has a hook for hooking the raised portion. The left end of the upper plate is connected to the upper end of the side plate, and the left end of the side plate is connected to the side plate. The front and rear ends of the upper plate extend downwards to form an upper front guard plate and an upper rear guard plate, respectively. The front and rear ends of the lower plate extend upwards to form a lower front guard plate and a lower rear guard plate, respectively. The upper plate is located above the corresponding end of the toner cartridge, and the lower plate is located below the corresponding end of the toner cartridge. The space formed between the upper and lower plates matches the space at the corresponding end of the toner cartridge. The upper plate covers the laser projection port.

[0016] The above technical solution has the following technical effects:

[0017] 1. This utility model's toner cartridge protective cover prevents dust from entering the toner cartridge through the laser projection port, thus protecting the components inside the toner cartridge. The toner cartridge protective cover is easy to install, use, and can be reused. The protective cover can be removed when the toner cartridge is to be used.

[0018] 2. The toner cartridge of this utility model can be protected from dust by using a toner cartridge protective cover, which can prevent physical impact and damage to the photosensitive drum and play a protective role in the photosensitive drum. Attached Figure Description

[0026] The present invention will now be described in detail with reference to specific embodiments.

[0027] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a toner cartridge protective cover includes an upper plate 1, a lower plate 2, and a side plate 3. The upper plate 1 has a hook 4 at its right end for hooking the raised portion 102 of the toner cartridge. The left end of the upper plate 1 is connected to the upper end of the side plate 3, and the left end of the lower plate 2 is connected to the side plate 3. The front and rear ends of the upper plate 1 extend downwards to form an upper front guard plate 11 and an upper rear guard plate 12, respectively. The front and rear ends of the lower plate extend upwards to form a lower front guard plate 21 and a lower rear guard plate 22, respectively. The space formed between the upper and lower plates matches the space at the corresponding ends of the toner cartridge. The upper plate, lower plate, and side plate are all made of plastic.

[0028] Working principle: When using, such as Figures 4 to 7 As shown, the end 210 of the toner cartridge containing the waste toner compartment is placed within the space between the upper and lower plates, with the upper plate above the corresponding end of the toner cartridge and the lower plate below it. Utilizing the elastic deformation of the plastic, the hook engages with the raised portion 102 of the toner cartridge, thus securing the toner cartridge protective cover to the cartridge. The upper plate then blocks the laser projection port 101 of the toner cartridge. This prevents dust from entering the toner cartridge through the laser projection port, protecting the components inside. The toner cartridge protective cover is easy to install, use, and reusable. When the toner cartridge is to be used, the protective cover can be removed.

[0029] Example 2: In this example, the front end of the side panel extends into a side front guard plate 31 towards the right end of the upper panel. This is more conducive to positioning and nesting with the toner cartridge during application.

[0030] The side front skid plate is integrated with the upper front skid plate and the lower front skid plate.

[0031] The rest is the same as in Example 1.

[0032] Example 3: In this example, the rear end of the side panel extends into a side rear guard plate 32 towards the right end of the upper panel. This is more conducive to positioning and nesting with the toner cartridge during application.

[0033] The side rear guard plate is integrated with the upper and lower rear guard plates.

[0034] The rest can be the same as in Example 1 or Example 2.

[0035] Example 4: In this example, the right end of the lower plate is provided with a photosensitive drum placement groove 5.

[0036] The wall of the photosensitive drum placement groove 5 is arc-shaped. During use, the photosensitive drum is located within the placement groove. This protects the photosensitive drum from external contact and prevents it from being scratched or abraded by foreign objects. The rest is the same as in Embodiment 1, Embodiment 2, or Embodiment 3.

[0037] Example 5: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a toner cartridge includes a main frame, a housing 100, a photosensitive drum 51, and a waste toner container. The main frame is located inside the housing, and the photosensitive drum 51 is mounted on the main frame. The top surface of the housing has a laser projection port 101, and the housing has a raised portion 102. It also includes a toner cartridge protective cover 200, which includes an upper plate, a lower plate, and side plates. The right end of the upper plate has a hook for hooking the raised portion. The left end of the upper plate is connected to the upper end of the side plate, and the left end of the side plate is connected to the side plate. The front and rear ends of the upper plate extend downwards to form an upper front guard plate and an upper rear guard plate, respectively. The front and rear ends of the lower plate extend upwards to form a lower front guard plate and a lower rear guard plate, respectively. The upper plate is located above the corresponding end of the toner cartridge, and the lower plate is located below the corresponding end of the toner cartridge. The corresponding end of the toner cartridge is the end containing the waste toner container. The space formed between the upper and lower plates matches the space of the corresponding end of the toner cartridge. The upper plate blocks the laser projection port 101.

[0038] The lower plate has a photosensitive drum placement slot on its right end.

[0039] The walls of the photosensitive drum placement slot are arc-shaped.

[0040] Working principle: As described in Examples 1 to 4, this example can use a drum toner cartridge protective cover to protect the drum toner cartridge from dust, which can prevent physical impact and damage to the photosensitive drum and protect the photosensitive drum.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
