In one example aspect, an electronic candle device includes a flame sheet and a candle body. The candle body includes an upper housing that comprises an opening, a lower housing, an extendable and retractable apparatus coupled to the upper housing and the lower housing, and a motor coupled to the extendable and retractable apparatus. Upon driven by the motor, the extendable and retractable apparatus is configured to pull the upper housing and the lower housing together to at least partially overlap with each other or separate the upper housing and the lower housing such that a height of the electronic candle device is adjustable.
