Abstract

The invention discloses a base seat for a bladeless fan. The base seat for the bladeless fan comprises a housing and a power system, wherein the power system is arranged in the housing, and the power system comprises an impeller shell, an impeller and a motor. The impeller shell is arranged on the housing, the impeller is arranged in the impeller shell, the motor is used to drive the impeller, and a backflow cavity is formed in the impeller shell so as to prevent airflows from flowing back. The invention furthermore provides the bladeless fan. According to the base seat for the bladeless fan and the bladeless fan, the backflow cavity is formed in the impeller shell, the backflow cavity can prevent the airflows from flowing back, and therefore noises caused by the airflows flowing back are reduced.

Description

technical field [0001] The invention relates to the field of fans, in particular to a base for a bladeless fan and the bladeless fan. Background technique [0002] The airflow in the prior art bladeless fan base will generate noise due to backflow. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention needs to provide a base for a bladeless fan. [0004] The present invention also needs to provide a bladeless fan. [0005] A base for a bladeless fan according to a preferred embodiment of the present invention includes a casing and a power system. The power system is accommodated in the housing, the power system includes an impeller casing, an impeller and a motor, a first air inlet is formed on the housing, the housing is cylindrical and the first air inlet is opened on the housing. An air inlet protrudes radially outward. The impeller casing is erected ...
