Air ducts are made of various different materials, such as steel, aluminum alloy, fiberglass, and plastic, etc. After long-term use, impurities such as dust, hair, and bacteria will adhere to the inside of the air duct. In order to ensure the cleanliness of the gas transported through the air duct, a plasma sterilization and disinfection purification device needs to be installed inside the air duct.

[0003] The utility model with the publication number of CN216953390U discloses a plasma sterilization and disinfection purification air duct device, which specifically relates to the technical field of air duct purification. It includes a first air delivery pipe and a second air delivery pipe. The first air delivery pipe is arranged on the left side of the second air delivery pipe. A plasma generator is embedded in the first air delivery pipe. A filter screen is arranged on the right side of the first air delivery pipe. A flipping mechanism is arranged on the outer side of the filter screen. A fan is embedded in the second air delivery pipe. Connecting pieces are integrally installed on the upper and lower outer surfaces on the right side of the first air delivery pipe and the upper and lower outer surfaces on the left side of the second air delivery pipe. Locking pieces are arranged on the upper side of the two upper connecting pieces and the lower side of the two lower connecting pieces. Locking blocks are integrally installed on the left and right sides of the outer surface of the two locking pieces. This utility model can sterilize and disinfect the air duct and filter it. At the same time, it saves the time for removing and installing the filter screen and improves the cleaning efficiency of the filter screen.

[0004] When the above technical solution is in use, air enters from the left side of the first air duct. When passing through the plasma generator, the plasma generated by the plasma generator will sterilize and disinfect the air. The air after sterilization and disinfection enters the second air duct from the right side of the first air duct after being filtered by the filter screen, thereby realizing the sterilization and disinfection process of the present utility model. After using for a period of time, the staff separates the first air duct and the second air duct, starts the driving motor, and the output end of the driving motor drives the first transmission shaft and the first bevel gear to rotate, thereby realizing the rotation of the second bevel gear, and finally realizing the outward flipping of the filter screen, which is convenient for the staff to clean the filter screen. During the cleaning process, there is no need to disassemble the filter screen, saving the time for disassembling and installing the filter screen, thereby improving the cleaning efficiency; however, when cleaning the filter screen in the above solution, it is necessary to separate the first air duct and the second air duct.

[0032] In this embodiment, the first air duct 1 provided in the plasma sterilization, disinfection and purification air duct device can convey air after being connected to the second air duct 2. A exhaust fan 3 is installed inside the second air duct 2. Starting the exhaust fan 3 can accelerate the air flow speed inside the air duct. While the air is flowing inside the duct, the filter plate 5 installed inside the first air duct 1 can filter certain impurities such as dust and hair in the air. After the air is filtered, a large amount of plasma can be generated by enabling the plasma generator 4 to disinfect, deodorize and decontaminate the air, thereby enhancing the sterilization, disinfection and purification effect of the air inside the air duct, and at the same time preventing impurities such as dust from adhering to the inner wall of the air duct. The present application first filters the air through the filter plate 5 and then purifies the air using the plasma generator 4, which can also reduce the damage of impurities such as dust to the plasma generator 4 and can more effectively remove fine particles and harmful substances in the air. Further, an adjustment component 6 is provided on the first air duct 1. When the adjustment component 6 is started and under the limitation of the first air duct 1, the movable mounting strip 7 can be adjusted to move up and down inside the first air duct 1. By the movement of the movable mounting strip 7, the cleaning brush 8 can be controlled to scrape and clean the side of the filter plate 5 away from the exhaust fan 3. The present application cooperates with the adjustment component 6, the movable mounting strip 7 and the cleaning brush 8, which can replace the way of manually cleaning the filter plate 5 by personnel, thereby saving the use of manpower and making the cleaning operation of the filter plate 5 more convenient, making the present application more conducive to practical use.
