Description

Fan and oil smoke processing apparatus Technical Field The utility model relates to the technical field of household appliances, in particular to a fan and an oil smoke treatment device. Background The range hood comprises a fan, the fan comprises a volute, an impeller and a motor component, an air inlet is formed in the volute, the impeller is arranged in the volute, the motor component can drive the impeller to rotate, the fan sucks gas from the center based on the action of centrifugal force and accelerates the gas through the impeller rotating at high speed, then the gas is discharged along the radial direction, so that the pressure and kinetic energy of the gas are increased, the volute is used as an important component of the fan, and the volute is mainly used for guiding airflow and providing a space for the impeller to operate. The traditional volute is usually made of all-metal, and the all-metal volute is high in strength, but high in cost and heavy in weight, so that the cost and the usability of the volute in the prior art are difficult to be considered, and the volute has a certain limitation in practical application.
