Abstract

The invention discloses a liftable fan based on a stainless steel impeller. The liftable fan comprises a housing, an impeller and a motor, wherein the motor is connected with the impeller; the impeller is limited in an inner cavity of the housing; an air inlet and an air outlet are formed in the housing; lifting type supporting legs are arranged on the bottom of the housing and the bottom of the motor; and each lifting type supporting leg comprises a straight barrel, a lengthened supporting rod, a supporting block and a supporting spring. A first filter screen assembly is further arranged between the impeller and the air inlet. The liftable fan has the advantages of being good in supporting stability and high in cleanliness of air discharged from the air outlet.

Description

technical field

[0001] The invention relates to the technical field of impeller application, in particular to a liftable fan based on a stainless steel impeller. Background technique

[0002] The impeller refers to the disc equipped with moving blades, including closed impeller, front semi-open impeller, rear semi-open impeller, open impeller and other forms. The impellers in the prior art are mostly used in technical fields such as liquid pumps or fans.

[0003] When it is used in a liquid pump, the motor rotates to drive the impeller to rotate, and its high-speed rotation causes the liquid to generate centrifugal force, so that a vacuum is generated in the middle of the impeller, and the liquid is continuously sucked into the impeller to increase the kinetic energy of the liquid and play a driving role. When it is applied in the fan, similarly, its rotation generates centrifugal force, throws the air out of the impeller, collects it in the housing to increase the pressure...
