When the first sway unit 51 receives the first current, a first magnetic field will be generated. When the second sway unit 51 receives the second current, a second magnetic field will be generated; since the directions of the first current and the second current are opposite, the first magnetic field and the second magnetic field will repel each other (for example, the north pole of the first magnetic field is close to the north pole of the second magnetic field, such that the first magnetic field and the second magnetic field repel each other), whereby the repellent magnetic field will be formed between the first sway unit 51 and the second sway unit 52. The repellent magnetic field keeps the first sway unit 51 away from the second sway unit 52, allowing the first sway unit 51 to sway above the second sway unit 52. The swaying of the first sway unit 51 causes the translucent shell 20 to sway along the sway directions M, M′ via the connecting unit 40. When the translucent shell 20 sways, the circuit board 70 will also control the light emitting unit 30 to emit light; therefore, the swaying translucent shell 20 and the shining light emitting unit 30 represent the shape of a candle flame and the effect of a candle flame swaying slightly in an air current.
Please refer to FIG. 8 regarding the electric flameless candle of the present invention. FIG. 8 illustrates a partial drawing of the electric flameless candle in the second embodiment of the present invention.
As shown in FIG. 8 the difference between the first embodiment and the second embodiment is that, in the second embodiment, the electric flameless candle 1a does not include the supporting unit 120 (as shown in FIG. 3); furthermore, the light emitting unit 30a does not has the dome top, and the light emitting unit 30a includes a tip 31. The tip 31 touched and supports the bottom of the translucent shell 20; whereby, when the electromagnetic sway module 50 sways, the tip 31 can let the translucent case 22 of the translucent shell 20 be stable via the supporting, to prevent the translucent case 22 to be affected by the swaying of the electromagnetic sway module 50 and to be gradually loose.
Via the design of the electric flameless candle 1 of the present invention, the shape of a real candle flame and the effect of a candle flame swaying slightly in an air current can be represented, and the electric flameless candle 1 can emit the light without a flame, posing no risk of fire or air pollution.
