FIELD OF THE INVENTION

The present invention relates to the technical field of decorative illumination, more particularly to an electronic simulation candle.

BACKGROUND OF THE INVENTION

To overcome defects of conventional candles, various electronic simulation candles emerge as required. With power conservation, low heat and other advantages, electronic simulation candles have gradually taken the place of conventional candles. Among the various electronic simulation candles in the market at present, there are very few electronic simulation candles, the flame of which looks more dynamic, particularly produces an effect of flickering in the wind. The degree of simulation is limited.

A similar simulation candle structure may be seen in U.S. Pat. Nos. 8,550,660, 8,534,869, 8,342,721 and etc. That is, a permanent magnet is provided at the bottom end of a flame piece, so that a solenoid coil below the flame piece drives the flame piece to generate a swing. However, the disclosed flame piece is pivoted at an upper opening of the mechanism via a wire, so the visual aesthetics will be destroyed by the wire when viewers get close to appreciate the simulation candles. In addition, as the flame piece consists of a flexible piece body, the flame piece, without any special construction processing, just can form a swing of a single color under the coordination of an irradiation light source. As a result, the simulation effect will be greatly reduced in the case that the flame core cannot be displayed separately.

In addition, a similar simulation candle structure may also be seen in US Patent publication US2012/0134157A1. That is, a permanent magnet is also provided at the bottom end of a flame piece, so that a solenoid coil below the flame piece drives the flame piece to generate a swing. However, the disclosed flame piece is formed by allowing a support rod horizontally spanning over a central through hole to pass through the flame piece, so the visual aesthetics will be destroyed by the support rod when viewers get close to appreciate the simulation candles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will be described as below in details with reference to drawings by specific embodiments.

FIG. 1toFIG. 3show a first embodiment of the present invention. The disclosed electronic simulation candle mainly comprises a power supply base10, a power driven device20, a flame piece swinger30and a light source fixation base40. The power driven device20is electrically connected to the power supply base10and disposed above the power supply base10. The light source fixation base40is disposed above the power driven device20. The flame piece swinger30is disposed between the power driven device20and the light source fixation base40. The power supply base10is an upright base having an accommodation space11therein, which accommodation space11can be used for accommodating batteries (not shown) and then closed via a cover plate12on the bottom thereof. A circuit board13electrically connected to the power supply base10is provided outside the power supply base10. A fixed base14is disposed in the top center of the power supply10.

The power driven device20consists of a chassis22which is provided with a gear set21therein and sheathed on the fixed base14. An output rotating shaft23of the gear set21extends upward out from the top wall of the chassis22and sheathed with a turntable25. A driving lever26protruded upward is provided on the outside of the upper surface of the turntable25. In addition, a fixed column27having a fixed slot271is provided on the upper surface of the chassis22.

The upper half31of the flame piece swinger30is a flame piece body32having a concave surface321. A hollow tapered swinger33expanding gradually from up to down is integrally disposed below the flame piece body32. On the side wall of the hollow tapered swinger33, provided is an opening331, and provided also is a support rod34capable of being inserted into the fixed slot271. Of course, the support rod and the fixed column may form an integrated structure. The support rod34is a slender rod structure having an upper half bent towards the center of the power driven device20first and then extending upward. The upper half341of the support rod34is able to be inserted upward into the hollow tapered swinger33, with its top342supporting against the inside top of the hollow tapered swinger33. Left and right limiting lugs332and333are provided on an outside bottom edge of the hollow tapered swinger33, respectively. The left and right limiting lugs332and333are rightly positioned on the top inside of the rotating arc of the driving lever26.

Certainly, the opening may be also provided on the bottom of the hollow tapered swinger. When the opening is provided on the bottom of the hollow tapered swinger, the support rod is an upright elongated rod (not shown).

The light source fixation base40is fixed above the power driven device20. In addition to a central through hole41, the light source fixation base40, on a side thereof, is provided with a light source base43obliquely passing through the central through hole41upward and fixedly provided with an irradiation light source42. The irradiation light source42faces the concave surface321of the flame piece body32in addition to being electrically connected to the circuit board13.

When the gear set21is enabled by the control of the circuit board13to drive the driving lever26to rotate forwardly to push the right limiting lug333, the flame piece swinger30may swing by using the top342of the support rod34as a fulcrum (as shown inFIG. 2). In this case, the turntable25will rotate backwardly due to the push resistance to further push the left limiting lug332. Similarly, the flame piece swinger30may swing backwardly by using the top342of the support rod34as a fulcrum. The flame piece body32of the flame piece swinger30may swing in the central through hole41of the light source fixation base40. In addition, as the irradiation light source42faces the concave surface321of the flame piece body32, a simulation effect of combustion flame will be achieved through the swing of the flame piece body32in coordination with the irradiation light source42.

In addition, an upright slot322may be further disposed at a near-bottom end of the flame piece body32. When the flame piece body32swings and thus forms a simulation effect of combustion flame, the upright slot322may further form a shape of a flame core, so that the combustion flame formed in the present invention has a better simulation effect.

Certainly, a flame core (not shown) having a better simulation effect may be further formed at the near-bottom end of the flame piece body by means of drawing, printing or attaching.

FIG. 4andFIG. 5show a second embodiment of the present invention. The structure of the electronic simulation candle disclosed by this embodiment is roughly the same as that of the first embodiment. However, the difference is that the power driven device20′ consists of a chassis22′ with a solenoid coil28provided therein; and that the bottom of the flame piece swinger30is provided with a permanent magnet35, as a result, the solenoid coil28generates a magnetic field continuously under the control of the circuit board13, so that the flame piece swinger30with a permanent magnet35provided on the bottom may generate a swing (not shown) by using the top342of the support rod34as a fulcrum, and the flame piece body32generates a swing which looks like flame under the coordination of the irradiation light source42. The permanent magnet may be a round flat magnet or an annular magnet.

In addition,FIG. 6shows a third embodiment of the present invention. A modification is that the fixed column27′ for inserting the support rod34is provided on the outer side of the upper surface of the turntable25′. In addition, left and right limiting stand columns29and29′ are provided on the chassis22′ outside the turntable25′. A positioning driving lever251′ (as shown inFIG. 7) extending outward and rightly positioned between the left and right limiting stand columns29and29′ is provided on the outer edge of the turntable25′. The gear set21is enabled by the control of the circuit board13to drive the positioning driving lever251′ to rotate forwardly to push the right limiting stand column29′ and to rotate backwardly to push the left limiting stand column29. In such an order, the turntable25′ continuously rotates forwardly and backwardly, so that the flame piece swinger30may swing back and forth around the top342of the support rod34, and the flame piece body32generates a swing which looks like flame under the coordination of the irradiation light source42.
