[0002] A fan is a gas compression and gas delivery machine that converts the mechanical energy of rotation into gas pressure energy and kinetic energy and delivers the gas. The main structural components of a fan are impeller, casing, air inlet, bracket, motor, pulley, coupling, muffler, transmission parts (bearings), etc. A fan is a device that relies on input mechanical energy to increase gas pressure and deliver gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. The fans usually include ventilators, blowers, and wind turbines. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings for ventilation, dust removal and cooling, ventilation and air induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc., and the wind guide is a device used to improve the efficiency of the ventilation system and reduce noise. It is commonly used in ventilation systems in industrial, commercial or residential buildings to guide the airflow generated by the fan and deliver it efficiently to the target area. The main function of the air duct is to guide the air flow, and it is usually used in buildings or vehicles. They can help regulate temperature, humidity and air quality while improving ventilation efficiency. In buildings, air ducts can discharge hot air and alleviate the problems of heat accumulation and poor ventilation. In vehicles, air ducts can improve air flow and increase passenger comfort. However, general air ducts cannot be adjusted in length, have poor flexibility and adjustability, and are difficult to meet different length requirements. They are also loud and affect the work of others.
