Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of printers, and in particular relates to a printer toner cartridge protection cover. Background Art
[0002] The rapid development of printer technology, especially the popularization of laser printing technology, has made high-quality and efficient document output a normal practice for office and home printing. In this technology system, the toner cartridge plays a pivotal role. It is not only the core component of imaging, but also a key factor affecting print quality. The precise internal structure and special coating design of the toner cartridge require extreme protection when not in operation and during transportation to prevent any physical damage, static electricity accumulation, dust pollution or humidity, which may directly lead to print quality problems and even shorten the service life of the toner cartridge.
[0003] Traditional protective covers mostly rely on a single hard plastic or metal material. The original intention of this design is to provide a physical barrier to block direct collisions and scratches. However, this single-material protection scheme ignores the complex threats faced by toner cartridges in complex and changeable usage environments. In particular, when the toner cartridge is subjected to external impact, the hard material can block direct impact, but it cannot effectively absorb and disperse the impact force. This is like transmitting the impact force directly to the toner cartridge without buffering, which can easily cause minor damage to the internal structure of the toner cartridge. In the long run, it not only affects the print quality, but also greatly shortens the service life of the toner cartridge. In addition, the fixed design of the hard material greatly reduces the protection effect when encountering non-vertical or side impacts. Traditional protective covers often ignore the oblique impact or multiple continuous slight impacts that the toner cartridge may be subjected to during transportation or improper storage. The force transmission in these cases is often more complicated, and the hard shell of a single material is difficult to cope with, resulting in a significant increase in the risk of toner cartridge damage. In addition, due to the hardness characteristics of the material, once it is impacted, the hard shell itself may also crack or break, and then directly damage the toner cartridge, which violates the original intention of protection. Utility Model Content
[0004] In view of this, the utility model provides a printer toner cartridge protective cover to solve the problem that the traditional printer toner cartridge protective cover only relies on hard materials to resist external impact, resulting in damage to the toner cartridge when subjected to strong impact.
[0005] The utility model is achieved in this way:

[0007] The dot matrix structure includes a plurality of convex dots, the convex dots follow a geometric arrangement rule, the height of the convex dots is between 0.1 mm and 1 mm, and the diameter is between 0.5 mm and 2 mm.
[0008] The technical effect of the printer drum protective cover provided by the utility model is as follows: the dot matrix structure follows a certain geometric arrangement rule, such as hexagonal, square or triangular arrangement, to ensure that the distance between dots is uniform, and the entire dot matrix distribution is dense and orderly. Such an arrangement can evenly disperse the pressure on the drum surface and avoid deformation caused by local concentrated force.
[0009] On the basis of the above technical solution, the printer cartridge protection cover of the utility model can also be improved as follows:
[0010] The shell is made of engineering plastic or metal material, with a thickness ranging from 0.5 mm to 2 mm, and a rebound time of the shell is between 0.1 second and 1 second.
[0011] Furthermore, the lining is made of a polymer material and has a thickness at least 0.2 times the thickness of the outer shell.
[0012] Furthermore, an inclination angle is provided at the junction between the inner wall of the outer shell and the edge of the lining, and the inclination angle is 2 to 5 degrees.

[0016] Furthermore, the connection mechanism is specifically one of a snap connection, a bolt fixation, and an adhesive.
[0017] Furthermore, the shock-absorbing material includes one of ethylene-vinyl acetate copolymer, polypropylene foam and polyurethane foam.
[0018] The beneficial effects of adopting the above improvement scheme are: the shock-absorbing material can be EVA (ethylene-vinyl acetate copolymer), polypropylene foam (EPP) or polyurethane foam. These materials are light, highly elastic, have good shock absorption and sound insulation properties, and can be filled in the cavity formed by the hard shell and the soft lining, effectively absorbing and dispersing the vibration and impact transmitted to the toner cartridge, further improving the protection effect.
[0019] Furthermore, the polymer material includes one of silicone rubber, polyurethane foam, and thermoplastic polyurethane.
[0020] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: Silicone rubber: has excellent elasticity and weather resistance, fast rebound speed, can effectively absorb and disperse impact force, and at the same time has strong adaptability to the environment and is not easy to age.
[0021] Polyurethane foam: has excellent cushioning properties, can absorb a lot of impact energy, rebounds slowly, and is suitable for long-term protection and vibration reduction.
[0022] TPU (thermoplastic polyurethane): combines the elasticity of rubber and the easy processing of plastic. It is wear-resistant, tear-resistant, and rebounds quickly. It is suitable for manufacturing protective parts that require quick response.

[0024] Comprehensively improved protection performance: Through the use of a multi-layer composite structure design, combined with the dual protection of a soft lining and a hard shell, efficient absorption and dispersion of external forces are achieved. The soft lining uses its highly elastic material properties to effectively absorb impact energy and reduce the force directly transmitted to the toner cartridge, while the hard shell provides a hard external protection to prevent scratches and hard object impacts, thereby greatly improving the safety factor of the toner cartridge under various conditions;
[0025] Optimized impact energy management: Based on the design principle of buffer structure, the material and shape of the lining are carefully calculated. When impacted, the material can dissipate energy through deformation and then quickly recover to its original state, avoiding damage to the drum caused by energy accumulation. This design can minimize damage to the drum even when it is hit hard, keeping its functions intact.
[0026] Enhanced environmental adaptability: The protective cover is designed with dust and moisture resistance in mind, and uses microporous breathable material to balance the internal and external air pressure while preventing dust intrusion, ensuring that the toner cartridge is not affected by moisture and pollutants during storage, extending the service life of the toner cartridge and maintaining print quality;
[0027] Humanized operation experience: Innovative connection and fixing mechanisms, such as quick installation buckles and rotating locks, simplify the installation and removal process of the toner cartridge, significantly improving the convenience and efficiency of user operation. In addition, the transparent window design allows users to intuitively view the status of the toner cartridge without frequently opening the cover for inspection, which is convenient and efficient.

The hard shell is made of high-strength and wear-resistant materials, such as ABS or PC plastic, to provide a solid external barrier for the toner cartridge. The combination of the two realizes all-round protection of the toner cartridge;
[0078] Dynamic energy absorption and dispersion mechanism: Based on the shock wave propagation and energy conversion principle in physics, the microstructure design of the soft lining (such as micro-convex dot array) can effectively change the propagation path of the shock wave, absorb the impact energy through material deformation, and convert it into heat energy or other forms of energy dissipation, thus preventing the energy from being directly transferred to the drum;
