Description

Rechargeable Tealight Oscillating Flame Electronic Candle Technical Field

[0001] The invention relates to the technical field of simulated electronic candles, in particular to a rechargeable tealight swinging flame electronic candle. Background Art

[0002] Candles, as an important decorative item, are widely used to set the mood at important occasions such as birthday parties and candlelight dinners. However, traditional candles not only produce smoke and pollute the environment, but the open flame also poses a safety hazard. Consequently, traditional candles are increasingly being replaced by electronic candles. Tealight electronic candles, typically smaller than 50 mm in diameter and less than 40 mm in height, are a key category of electronic candles and are widely used in decorative settings. Rechargeable electronic candles can also save consumers money.

[0003] To create the illusion of flickering candlelight, patent CN 203375334 U discloses an electronic candle with a swaying flame head. This electronic candle achieves the effect of a swaying flame head, enhancing the realism of electronic candles compared to existing designs with fixed flame heads. However, due to the relatively small overall size and limited internal space of tealight electronic candles, patent CN 203375334 U does not provide a solution for achieving a swaying flame head that simulates a natural swaying effect within such a confined space, while also providing a rechargeable function.

The flame head movable assembly includes a flame head 310, a light source 320, a light source bracket 330, a magnet 340, and a weight 350. The flame head 310 comprises a three-dimensional flame-shaped portion and is hollow inside, at least partially located above the upper opening of the housing 100. The light source 320 is disposed within the flame head 310, emitting light from within the flame head 310 to illuminate the flame head from the inside out. The light source 320 is disposed at the upper end of the light source bracket 330. The first electrode 321 of the light source 320 is electrically connected to the control circuit board via a first light source conductive wire 360, and the second electrode 322 of the light source 320 is electrically connected to the control circuit board 700 via a second light source conductive wire 370. The support assembly includes a support frame 410 and a crossbar 420. The crossbar 420 is fixedly supported on the support frame 410, which is in turn fixedly supported on the bottom housing 200. The light source bracket 330 is movably supported on the crossbar 420. The magnet 340 is fixed at the center of the lower end of the light source bracket 330, and the weight 350 is fixed at the lower end of the light source bracket 330. The bottom housing 200 includes a bottom surface 210, a vertical wall 220, and an interior space 230 formed by the bottom surface and vertical wall. The control circuit board 700 is supported on the upper end surface 221 of the vertical wall of the bottom housing 200. The rechargeable battery 600 is disposed below the control circuit board 700 and within the interior space 230 of the bottom housing 200.
