A modeling method for a fan assembly includes-comprises constructing non-axially symmetric end wall curved surfaces in a cascade channel. Constructing the non-axially symmetric end wall curved surfaces in the cascade channel includes: determining, using a flow path design method for a dual flow path of a blade end area, an initial axially symmetric curve radius and a recessed curve lowest point radius of non-axially symmetric curved surfaces; and constructing the non-axially symmetric end wall curved surfaces in the cascade channel according to the initial axially symmetric curve radius and the recessed curve lowest point radius. The modeling method constructs the non-axially symmetric end wall curved surfaces in the cascade channel using the flow path design method for a dual flow path of a blade end area, to implement the control of flow directions by the non-axially symmetric curved surfaces, thereby reducing end wall loss.

A power plug is provided. The power plug may include a plug insert having a handle, and a plug body including a plurality of insulation layers and a plurality of conducting strips sandwiched between the pluralities of insulation layers. Each of the plurality of conducting strips may have an end extending into the handle and the other end forming or electrically connected to a conducting contact point exposed on a surface of the plug body.
