Abstract

A magnetic levitation imitation flame device includes a mounting base, a flame member, a positioning bracket, a first magnet, and a second magnet. The positioning bracket is fixed in the mounting base. The first magnet is disposed on the flame member. The flame member is disposed on the positioning bracket and protrudes outwards from the mounting base. The second magnet is fixed at a lower end of the positioning bracket. The first magnet and the second magnet are arranged up and down. Magnetic poles thereof facing each other have same polarity so that the flame member is levitated relative to the positioning bracket under a repulsive force of the first magnet and the second magnet. Thus, the flame member swings with big angle, naturally and realistically, and saves electric energy. In addition, an imitation flame lamp is also provided.
