Description

technical field [0001] The present application relates to the field of ventilation equipment, in particular to a fan. Background technique [0002] At present, the fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine; the fan generally includes a fan housing, a motor and an impeller. The rear end of the fan housing is equipped with a motor and an impeller. It is installed in the fan casing and connected with the output shaft of the motor. During operation, the output shaft of the motor drives the impeller to rotate, so as to achieve the purpose of exhausting gas. [0003] The existing patent application number is the Chinese patent of CN201510882656.5, which proposes a fan. The main points of its technical solution are: including a casing, the casing is provided with an air inlet and an air outlet, and the casing is provided with The rotating mechanism and the fan motor that drives the r...
