[0002] An air duct is a duct system used for air transportation and distribution, and there are two types: composite air ducts and inorganic air ducts. In order to detect the temperature and humidity inside the air duct, a temperature and humidity sensor is usually installed inside the air duct. However, most of the existing temperature and humidity sensors are directly and nakedly installed. During long-term use, the outer side of the sensing port of the temperature and humidity sensor is prone to being contaminated with dust and other pollutants, resulting in inaccurate detection results of the temperature and humidity sensor. Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a filtering mechanism for an air duct temperature and humidity sensor is provided, with the expectation of achieving a more practical value.

One end of the bolt passes through the connecting seat I and the connecting seat II and is threadedly connected with a nut. Two groups of connecting rods are symmetrically and fixedly installed on the outer side of the connecting cylinder. Rotating cylinders are rotatably connected to the outer sides of the two groups of connecting rods. Threads are provided inside one end of the two groups of rotating cylinders, and a screw rod is threadedly connected thereto.

[0005] Further, a sealing ring I is fixedly adhered to the bottom side of the connecting ring.
