[0014] 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, and not all embodiments. 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 protection scope of the present utility model.

[0015] Specific implementation examples are given below.

[0016] Please see Figures 1-4 This utility model provides a vibration-proof and loose compaction mechanism for a laser printer toner hopper, including a toner hopper 1, a cover plate 101 on the top of the toner hopper 1, a plurality of first circular holes on the top of the cover plate 101, and a compaction component 2 disposed inside the plurality of first circular holes. The compaction assembly 2 includes a cylinder 201 fixedly connected within several first circular holes. A push rod 202 is slidably connected inside the cylinder 201. A push plate 203 is fixedly connected to the bottom of the push rod 202. A first spring 204 is fixedly connected to the bottom of each push plate 203. A compaction plate 205 is elastically connected to the bottom of each push plate 203 via the first spring 204. During operation, the toner cartridge 1 holds the toner inside the printer. During printer operation, a certain degree of vibration is generated, which is transmitted to the toner inside the toner cartridge 1, causing the toner to disperse and affecting the smoothness of toner dispensing. The cover plate 101 mounted on the top of the toner cartridge 1 protects the toner inside the toner cartridge 1 and also provides installation space for subsequent components. The top has three sets of first circular holes arranged in a linear array. The cylinders 201 of the compaction assembly 2 are rigidly connected inside the holes. The outer diameter of the cylinders 201 matches the inner diameter of the first circular holes, so that the cylinders 201 can be stably installed inside the first circular holes. The push rods 202 slidably connected inside the cylinders 201 play the role of transmitting force. The push plate 203 at the bottom of the push rods 202 can move synchronously with the movement of the push rods 202. At the same time, it can transmit the force to the first spring 204 at the bottom. Under the elastic action of the first spring 204, the compaction plate 205 at the bottom can adapt to the reduction of toner, so that the toner inside the toner tank 1 is always in contact with the compaction plate 205 and is always in a compacted state under the action of the first spring 204.

[0017] The interaction between spring 204 and compaction plate 205 provides continuous and appropriate pressure to the toner in toner tank 1. Even if the printer vibrates during operation, it can prevent the toner from dispersing and separating, maintaining a compacted state at all times. The compaction plate 205 adaptively adjusts as the toner level decreases, maintaining contact with the toner throughout the process. This completely solves problems such as poor toner dispensing and toner interruption caused by vibration, ensuring stable print quality. Furthermore, such as Figure 1 and Figure 4 As shown, the bottom array of the toner cartridge 1 has several shock-absorbing components 3. The shock-absorbing components 3 include a telescopic rod 301 fixedly connected to the bottom of the toner cartridge 1. The telescopic rod 301 has a second spring 302 inside. During operation, the toner cartridge 1 is used to carry the toner in the printer. When the printer is running, it will generate a certain degree of vibration. By assembling the shock-absorbing components 3 at multiple important points at the bottom of the toner cartridge 1, the telescopic rod 301 in the shock-absorbing components 3 contacts the bottom of the toner cartridge 1 and the printer. The second spring 302 inside the telescopic rod 301 plays a role in relieving the vibration of the printer and reducing the force transmitted to the toner cartridge 1, thereby reducing the possibility of toner dispersion in the cartridge.

[0018] Furthermore, such as Figure 2As shown, several push rods 202 are fixedly connected to handles 206 at their tops. The outer diameter of the push plate 203 matches the inner diameter of the cylinder 201. During operation, the handles 206 fixedly connected to the tops of the push rods serve as the driving source of force. By gripping the handles 206, a downward force is applied, which is then transmitted through the push rods 202 to the compaction plate 205 at the bottom, thereby compacting the toner inside the toner tank 1. The size of the push plate 203 is adapted to the cylinder 201, allowing the push plate 203 to move smoothly along the axial direction of the cylinder 201, ensuring the stability of force transmission.

[0019] Furthermore, such as Figure 2 As shown, the inner wall of the toner tank 1 is equipped with a buffer pad. During operation, the buffer pad installed on the inner wall of the toner tank 1 can effectively buffer the impact force generated during the operation of the printer, and further protect the toner in the toner tank 1, reducing the dispersion of toner caused by vibration and collision with the wall of the toner tank 1.

[0020] Furthermore, such as Figure 3 As shown, the size of the compaction plate 205 matches the inner wall size of the toner tank 1. During operation, the size of the compaction plate 205 is precisely adapted to the inner wall of the toner tank 1, so that the compaction plate 205 can completely cover the toner in the toner tank 1, ensuring that uniform and comprehensive pressure is applied to the toner, thereby achieving a highly efficient compaction effect.

[0021] Furthermore, such as Figure 1 As shown, the cover plate 101 on the top of the toner tank 1 is designed to be detachable. When in operation, the cover plate 101 on the top of the toner tank 1 is designed to be detachable. After detachment, toner can be directly added to the toner tank 1. The operation is convenient and efficient. When the inside of the toner tank 1 needs maintenance or cleaning, the corresponding operation can be carried out quickly by simply opening the cover plate 101, which greatly improves the convenience of later maintenance.

[0022] Working Principle: The toner cartridge 1, as the core load-bearing component, stores printer toner. Vibrations during printer operation can easily cause toner dispersion within the cartridge, affecting toner flow. Therefore, a multi-layered structure works together to achieve both anti-loosening and compaction functions. First, the cover plate 101 not only protects the toner, but its three sets of first circular holes on top also provide an installation reference for the compaction component 2. The cylinder 201 is rigidly connected to the holes with precise dimensional matching, ensuring overall structural stability. The push rod 202 slides inside the cylinder, and the top handle 206 allows manual application of downward pressure, which is transmitted via the push plate 203 to the first spring 204, ultimately driving the compaction plate 205 to act on the toner. Because the compaction plate 205 and... The inner wall of the toner cartridge 1 is sized to fully cover the toner inside. Combined with the elastic adaptive characteristics of spring number one, it can maintain contact as the toner level decreases, always keeping the toner compacted. At the same time, several shock-absorbing components 3 arrayed at the bottom of the toner cartridge 1 form the first line of shock protection: the telescopic rod 301 connects the cartridge body to the printer, and the internal spring number 2 buffers vibration through elastic deformation, reducing the impact force transmitted to the cartridge. The buffer pad on the inner wall of the cartridge further absorbs residual vibration, reducing the risk of toner dispersion caused by collision with the cartridge wall. In addition, the detachable design of the cover plate 101 facilitates operations such as adding toner, maintenance, or cleaning, ensuring both shockproof compaction function and ease of use.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
