Abstract

The invention provides an electric fan which comprises a rotor component and a machine shell, wherein the rotor component comprises a bearing, a moving impeller and a magnetic ring; the magnetic ringand the moving impeller are correspondingly mounted at two ends of the bearing; the machine shell is equipped with a bearing chamber; the diameter of the magnetic ring is less than that of the bearingchamber; the magnetic ring is capable of penetrating through the bearing chamber; and after the mounting operation is completed, the moving impeller and the magnetic ring are correspondingly positioned at two ends of the bearing chamber. According to the electric fan provided by the invention, only one bearing is utilized, and the utilized bearing is positioned between the moving impeller and themagnetic ring which are mounted on a rotating shaft; during the assembling process, the magnetic ring penetrates through the bearing chamber; after the mounting operation is completed, the moving impeller and the magnetic ring are correspondingly positioned at the two ends of the bearing chamber; by the adoption of such a rotor component and machine shell assembling mode, the assembling operationcan be facilitated and the assembling process can be simplified; due to the use of only one bearing, the rotor component and machine shell assembling precision requirements are low, and the improvement of the assembling efficiency can be facilitated; and furthermore, the quantity of parts of the electric fan is reduced, so that the reduction of the product cost can be facilitated and the assembling efficiency can be further improved.

Description

technical field [0001] The invention relates to the technical field of electric fans, in particular to an electric blower, especially a high-speed electric blower. Background technique [0002] In the existing electric fans, the rotating shaft is usually supported by two bearings at both ends of the installed rotating shaft. In order to ensure the reliability of the electric fan, it is necessary to ensure that the two bearings have a high degree of coaxiality, resulting in high requirements for the assembly accuracy of the electric fan. , and the assembly is complicated. Contents of the invention [0003] The present invention aims to solve at least one of the above technical problems. [0004] Therefore, the object of the present invention is to provide an electric fan. [0005] In order to achieve the above object, the technical solution of the present invention provides an electric fan, including: a rotor assembly, the rotor assembly includes a bearing, a moving impel...
