[0002] An air duct refers to a major air-guiding device used for local ventilation. According to different manufacturing materials, it is divided into flexible air ducts made of canvas, artificial leather, plastic and rubber, and metal air ducts made of iron sheets and aluminum plates. Flexible air ducts are light in weight, and the connection and suspension are simple, but the ventilation resistance is large. Metal air ducts have small ventilation resistance, but occupy the cross-sectional area of ​​the shaft and tunnel. In addition, existing air ducts are often fixed on a plane by a fixed connection during use. However, when the air duct is damaged, it is not convenient to disassemble and replace it. In addition, the air inlet end of the air duct is often fixedly connected with a filter plate, which leads to clogging of the filter plate after long-term use and is difficult to replace quickly, greatly reducing the practicality of the air duct. Utility Model Content

When the filter plate 8 is inserted into the groove 16, the cooperation of the plug body 7 prevents the air containing impurities from directly entering the interior of the wind cylinder body 1 through the groove 16.

[0023] The fixing plate 2 is provided with a groove 16, in which a filter plate 8 is arranged, a toothed rod 11 is provided on one side of the filter plate 8, a gear 17 meshing therewith is provided on one side of the toothed rod 11, a rotating rod 6 is provided at one end of the gear 17, the rotating rod 6 is plugged into the fixing plate 2, one end of the rotating rod 6 passes through the fixing plate 2 and is fixedly connected to the gear 17, a connecting block 10 is fixedly connected to the wind cylinder body 1, and there are four connecting blocks 10, which are evenly distributed on the wind cylinder body 1. The gear 17 drives the toothed rod 11 to move by rotating the rotating rod 6, thereby realizing the rapid replacement of the filter plate 8, avoiding damage to the filter plate 8 and clogging of the filter plate 8 by debris, thereby affecting the normal use of the ventilation duct.

[0024] A sealing ring 5 is provided on one side of the connecting block 10, and a limiting groove 14 is provided on the connecting block 10.
