Abstract

The invention provides an electric fan, comprising: a rotor assembly and a casing, the rotor assembly includes a bearing, a moving impeller and a magnetic ring, and the magnetic ring and the moving impeller are respectively installed at two ends of the bearing; the casing has a bearing chamber, and the magnetic ring The diameter is smaller than the diameter of the bearing chamber, and the magnetic ring can pass through the bearing chamber. After the installation is completed, the moving impeller and the magnetic ring are respectively located at both ends of the bearing chamber. The electric fan provided by the present invention only uses one bearing, and the bearing is located between the moving impeller and the magnetic ring of the rotating shaft. When assembling, the magnetic ring passes through the bearing chamber. After the installation is completed, the moving impeller and the magnetic ring are respectively located At the end, this assembly method of the rotor assembly and the casing is convenient for assembly and simplifies the assembly process; since only one bearing is used, the assembly accuracy requirements for the rotor assembly and the casing are low, which is conducive to improving assembly efficiency; The number of parts is beneficial to reduce product cost and further improve assembly efficiency.

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...
