Abstract

The invention discloses an electric fan, which comprises a base, a motor machine set, fan blade seats and fan blades, wherein the base is provided with a connecting seat and the motor machine set; the motor machine set is arranged on the connecting seat of the base and provided with a mandrel; the fan blade seats are provided with first components and second components which are corresponding and provided with combination seats and combination sleeves respectively, the combination seats are provided with shaft holes, the first components and the second components are provided with a plurality of curved surfaces respectively, the curved surfaces of the second components are of a corresponding shape, the curved surfaces of the first components are provided with a plurality of protruded pillars, and the first components and the second components form fan blade accommodating grooves when the first components and the second components are mutually combined; the fan blades are provided with a plurality of the fan blade accommodating grooves matched with a plurality of the fan blade seats, and the fan blades are made of a foaming or flexible material into a plane shape and are provided with grooves and a plurality of holes; and the first components and the second components of the fan blade seats are combined with the fan blades to form the electric fan. The electric fan does not need to arrange a safety net, namely, the electric fan has safety design, can save manufacturing cost, can not resist air-out effect and improve air output.

Description

technical field [0001] The invention relates to an electric fan, in particular to a new type of electric fan whose fan blades are made of foaming or slightly soft materials that will not hurt even if they are touched. Background technique [0002] The fan blades currently on the market are all made of acrylonitrile-butadiene-styrene copolymer (ABS) rigid plastic materials. The fan blades made of the above-mentioned rigid plastic materials are hard to use When the fan blade is rotating, once the user touches the fan blade accidentally, it will cause injury. Therefore, the electric fans currently on the market all have a safety net. Although the safety net isolates the fan blades from the outside world, it often happens that users, especially children, reach into the safety net and are injured by the rotating fan blades. Incident, therefore, some electric fan manufacturers and relevant safety regulations require that the mesh of the safety net be reduced, which will affect th...
