Description

music craft candle

The utility model relates to a craft candle with music, which is especially suitable for use on festive occasions.

In the existing "birthday music candle" patent (Chinese Patent No.: 92221255.4) of this patent applicant, a kind of integrated circuit chip with a photosensitive control recording birthday song is designed at the bottom of the birthday candle, when the birthday candle is lit Finally, the candlelight is transmitted from the optical fiber embedded in the candle to the phototransistor placed in the candle base, triggering the conduction, so that the music integrated circuit is conducted, and the output signal is transmitted from the speaker after passing through the power amplifier. Once the candles are blown out, the music stops. The design has the following deficiencies: ① candlelight is transmitted to the phototransistor by the optical fiber, and the strength of the transmitted light source directly affects the trigger sensitivity of the phototransistor. The greater the amount of light source of the triode, the easier it is to trigger the photosensitive triode, but subsequently, the external light source absorbed by the optical fiber also increases, and the possibility of false triggering is also greater when there is no candle light source; if the optical fiber used is more The smaller the amount of candlelight absorbed, the less likely it is to trigger the phototransistor, and the false triggering phenomenon caused by external light interference can be reduced accordingly; This music candle can only be suitable for decoration on birthday cakes with a shorter lighting time, but not for other festive occasions that need to be lit for a long time and the sound of music can be controlled on demand.

The purpose of this utility model is to design a kind of musical craft candle which can not only reduce external light interference, but also has high sensitivity to candle light induction, and can artificially control the working state of music circuit, which is simple in structure, easy to use and widely used.

The purpose of this utility model is achieved in this way: the music craft candle is made up of candle, the optical fiber embedded in the candle, the candle holder placed under the candle and the music circuit with photoelectric element in the candle holder. The fiber is vertically embedded near the eccentric position of the candle wick. The bottom of the optical fiber is spherical to form a light guide bead. A light-shielding cap covering the photoelectric element is fixed at the bottom of the candle. There is a light-guiding bead embedded in the light-shielding cap. The eccentric hole, the candle and the shading cap rest on the candle holder and can rotate on the candle holder; the photoelectric element in the music circuit is placed in the middle of the candle holder, and a partial area is covered on the photosensitive surface of the photoelectric element It can filter out other light sources and pass through candlelight, and some areas can absorb the filter that blocks candlelight. The eccentric hole on the shading cap faces the top of this filter.

In this music craft candle, since the bottom of the optical fiber has a light guide bead that conducts and amplifies the candle light source, the optical fiber can be thinner, which not only reduces the interference of external light, but still ensures the sensitivity to candle light induction. In addition, since the entire photoelectric element is in the shading cap, and there is a filter on the photoelectric element to filter out the external light source, it can more effectively reduce the phenomenon of false triggering of the circuit caused by external light when there is no candlelight; the filter on the photoelectric element Because some areas of the film can pass through turbid light, and some areas can absorb candlelight, the eccentric hole embedded with light guide beads faces this filter. When the candle is artificially rotated, the light guide beads will rotate accordingly. When the bead is facing the transparent candlelight area of the filter, the candle light source will trigger the music circuit, and if it turns to the point where the light guide bead is facing the impermeable candlelight area of the filter, the music circuit will stop working, which achieves artificial control of the music circuit Purpose of work status. In addition, the craft candle has a simple structure and is very convenient to use, and can be used not only as a birthday candle, but also as craft candles for other festive occasions.
