The specific embodiment

Is the function and benefit of further understanding architectural feature of the present utility model in depth and can reach, now enumerates specific embodiment, and detailed introduction of conjunction with figs. is described as follows:

A kind of electronic candle lamp 10 as shown in Figure 1, comprises external charger 103, charging lamp socket 101 and candle lamp body 102, and this candle lamp body 102 places on the charging lamp socket 101 in the corresponding grooves.

Described candle lamp body 102 as shown in Figure 2, comprises lampshade 104, base 109, is arranged on the outer cover 106 that base 109 interior circuit board 108a, the LED bulb 107a that are electrically connected with circuit board 108a and one are with flame-shaped 105.Wherein, preferred two of LED bulb 107a combining up and down, and aligns the flame-shaped 105 of its lamp holder position and outer cover 106, outer cover 106 screens are connected to form the shell of whole candle lamp body 102 in the inside of base 109 by screens between lampshade 104 and the base 109.

Described charging lamp socket 101, the indicator lamp 107b (preferred herein LED bulb) that as shown in Figure 3, comprises loam cake 110, bottom 111, is arranged on the circuit board 108b in the bottom 111 and is electrically connected with circuit board 108b.Wherein, on be covered with the through hole 112 that passes for indicator lamp 107b lamp holder position, between bottom 111 and the loam cake 110 by being threaded.

With reference to Fig. 4, this figure is the circuit theory diagrams on the charging lamp socket 101 interior circuit board 108b, circuit board 108b is provided with inductive charging primary coil circuit, and this inductive charging primary coil circuit includes timing circuit, reset circuit, indicator light circuit and oscillating circuit.Insert external charging plug J1, configure the time of charging by chip IC 2, the output pin 3 that utilizes chip IC 1 is simultaneously to three groups of coil charges, and charging indicator light (LED) is lighted, after first group of output pin 3 by chip IC 1 connects resistance R 11, be connected with the base stage of triode Q4, to the oscillation circuit charging that constitutes by inductance L 1 and capacitor C 9; After second group of output pin 3 by chip IC 1 connects resistance R 13, be connected with the base stage of triode Q5, the oscillation circuit charging that constitutes by inductance L 2 and capacitor C 10; After the 3rd group of output pin 3 by chip IC 1 connects resistance R 15, be connected, the oscillation circuit that is made of inductance L 3 and capacitor C 11 charged, and produce the voltage of an alternation by these three groups of LC oscillation circuits with the base stage of triode Q6.When charging interval that chip IC 2 is set then, send a pulse signal, the base stage that connects triodes by resistance R 5 acts on the pin 4 of chip IC 1, and it is resetted, and stop charging, and charging indicator light (LED) extinguishes simultaneously.If in the time of setting, the phenomenon that overcharges is arranged, promptly when charging voltage is higher than the threshold value of chip IC 1 pin 6, then connects resistance R 9 and amplify by pin 7.
