[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A sterilization device for an air filter includes a fan 1, a drying cotton 2, and an air inlet box 3. The drying cotton 2 is located between the air inlet box 3 and the fan 1. A lower frame 4 is installed on the side of the air inlet box 3 away from the fan 1. An upper frame 5 is hinged to the lower frame 4. Several fixing plates 6 are arranged between the upper frame 5 and the lower frame 4. The fixing plates 6 are used to adsorb desiccant and disinfectant. A locking plate 7 is installed on the upper frame 5. A locking groove 8 is opened on the lower frame 4. A pressure plate 9 is elastically connected in the locking groove 8. A pull rod 10 is installed on the pressure plate 9. The end of the pull rod 10 away from the pressure plate 9 is located on the outside of the lower frame 4.

[0022] When desiccant or disinfectant needs to be added to several fixed plates 6 within the device, the operator pulls the lever 10 outwards. This causes the pressure plate 9 to move synchronously, preventing it from contacting the locking plate 7. Then, the upper frame 5 is rotated, causing the locking plate 7 to rotate and move to the outside of the locking groove 8, thus engaging the locking relationship between the upper frame 5 and the lower frame 4. This facilitates the addition of desiccant or disinfectant to the fixed plates 6. After addition, the lever 10 is pulled outwards again, and the upper frame 5 is rotated again, causing the locking plate 7 to fall into the locking groove 8. The lever 10 is then released, and the pressure plate 9 contacts the locking plate 7 under elastic force, completing the locking between the upper frame 5 and the lower frame 4. Locking or unlocking between the upper frame 5 and the lower frame 4 can be achieved by controlling the movement of the lever 10. This method is simple to operate, avoids the work of disassembling and assembling multiple sets of bolts in existing technologies, and provides convenience for the maintenance of the device.

[0023] Specifically, in this embodiment, a plurality of springs 11 are provided between the locking groove 8 and the pressure plate 9. The plurality of springs 11 are located on the side away from the locking plate 7, so that after the locking plate 7 falls into the locking groove 8, the springs 11 reset under the action of elastic force, causing the pressure plate 9 to contact the locking plate 7, thereby achieving the purpose of restricting the locking plate 7 within the locking groove 8.

[0024] Specifically, in this embodiment, a plurality of connecting blocks 12 are installed on the side of the locking plate 7 near the pressure plate 9. The thickness of the connecting blocks 12 is the same as the thickness of the pressure plate 9. A plurality of connecting grooves 13 are provided on the pressure plate 9. The connecting grooves 13 are adapted to the connecting blocks 12, so that after the locking plate 7 falls into the locking groove 8, when the pressure plate 9 moves closer to the locking plate 7 under the action of elasticity, the plurality of connecting blocks 12 will be engaged in the corresponding connecting grooves 13, thereby improving the connection stability between the locking plate 7 and the pressure plate 9.

[0025] Specifically, in this embodiment, a sliding hole 14 is provided on the lower frame 4. The sliding hole 14 is connected to the locking groove 8 and is adapted to the pull rod 10, so that the pull rod 10 can slide on the locking groove 8 through the sliding hole 14, thereby achieving the purpose of controlling the movement of the pressure plate 9 through the pull rod 10.

[0026] Specifically, in this embodiment, both the upper frame 5 and the lower frame 4 are provided with a plurality of snap-fit ​​slots 15. The snap-fit ​​slots 15 are adapted to the fixing plate 6, so that the operator can connect the fixing plate 6 to the lower frame 4 by inserting it into the lower frame 4. Then, the upper frame 5 is rotated, and the upper part of the plurality of fixing plates 6 is fixed by the snap-fit ​​slots 15 on the upper frame 5, so that the fixing plate 6 can be stably connected between the upper frame 5 and the lower frame 4.

[0027] Specifically, in this embodiment, the shape of the fixed plate 6 is adapted to the shape formed between the upper frame 5 and the lower frame 4, and the fixed plate 6 is provided with an adsorption sponge 16, which has a honeycomb structure. The honeycomb structure of the adsorption sponge 16 makes the airflow distribution more uniform when the air circulates, thereby avoiding insufficient contact of the sterilizing agent caused by uneven airflow distribution, and thus improving the sterilization quality.

[0028] Specifically, in this embodiment, the air inlet box 3 and the fan 1 are connected by bolts, and a silicone ring and a metal pressure ring are provided at the connection point. The silicone ring and the metal pressure ring fully cover the contact surface between the air inlet box 3 and the fan 1. The bolt connection makes it easy to remove the fan 1 from the air inlet box 3 to replace the drying cotton 2 inside the air inlet box 3. The silicone ring and the metal pressure ring further improve the sealing between the fan 1 and the air inlet box 3, preventing gas leakage.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
