The present invention is designed to operate a circuit that generates a melody or a light emitting diode (LED) light at a very high detection speed when a candle is lit, or to drive an electrically connected electronic device, an electronic device, or a toy. The present invention relates to a melody-generating candle, and to a candle that stops the operation of the circuit when the light is turned off and generates a melody by operating the circuit when the light is turned off.

In the conventional melody candle, when the wick is lit, the candle around the wick melts and rises to a certain temperature, so that the melody is generated by using a thermistor, which causes a very slow detection speed and short lifespan. That is, according to the first (a) and the first (b), the ceramic element (NTC) having a negative resistance to heat is used as a sensor. When the flame directly touches the sensor, the characteristic of the sensor changes. However, since the soldering part between the connecting light wire 2 and the sensor 1 and the connecting copper wire 2 is applied, the sensor 1 cannot be directly detected and the sensor 1 is placed on the candle surface away from the flame to indirectly detect the sensor ( 1) It was detected by melting the candle around 3 and raising it to a certain temperature. The biggest drawback was that the melody was detected very slowly only 1-2 minutes after the wick was lit.

Therefore, it is accompanied by the inconvenience that the melody does not occur immediately after many people wait in silence for a long time without the melody immediately when many people turn on the fire at the party or the celebration party.

Conventional melody candles having such drawbacks are not considered at all for the characteristics that require fast detection for the purpose of use and are pointed out as a disadvantage that cannot be avoided by the conventional sensing method.

Another drawback is that a conventional melody candle inevitably connects the connection between the sensor 1 and the built-in circuit in order not to prevent the sensor 1 from continuing to descend as it is worn on the candle drawing. 2) is used as a very thin, but in actual use, the sensor (1) continues to descend as the candle wears out, but as shown in FIG. 1 (b), the connecting copper line (2) is continuously exposed to the air and immediately touches the flame of the candle. Because it is melted, the life is shortened.

In particular, the closer the sensor 1 to the flame in order to increase the detection speed, the shorter the lifespan becomes.

Therefore, the present invention solves the above-mentioned shortcomings of the conventional melody-generating candles and is designed to directly sense the temperature of the flame 5, not the temperature of the melted candles, in order to increase the detection speed within 4-5 seconds. As a sensor (1), a bimetal switch (4) made of metal with no change in characteristics even at high temperature or a junction point (9) of a thermocouple generating heat power is used. It provides a photosensitive device that detects the light immediately.

And when the sensor 1 is located around the flame 5, the connection copper wire 2 so that the connection copper wire 2 is not exposed to the air in order to prevent blown of the connection copper wire 2 by the candle due to the shortening of the lifespan. It is to provide a pressure plate (6) for lowering the sensor (4) or the sensor (8) while always laid on the bottom surface, the technical configuration and effect of the present invention in detail according to the accompanying drawings Same as

As shown in FIG. 4, the pressure plate 6 having the wick 9, the passage hole 11 'and the application liquid distribution port 11 through which the candle solution can freely flow, and the unevenness 10 for melt flow. The junction point 8 of the thermocouple made of the bimetal switch 4 of FIG. 2 or the junction of the two kinds of metals of FIG. 3 is positioned close to the wick 9, or the photosensitive element 12 of FIG. Small diameter connection that is formed away from the wick 9 so that the flame 5 does not touch, and these heat sensing elements 4, 8 or photosensitive element 12 cannot beat the weight of the pressure plate 6 in the circuit. Candles connected under the pressure plate 6 by copper wire 2 or without any sensors 4, 8, 12 around the pressure plate 6, the connecting lamp line 2 and the flame 5 as shown in FIG. A photosensitive element 12 'is provided only inside the body, or two photosensitive elements 12', 13 are provided inside as shown in FIG. 6 (a). Opaque Candle Light Blocker (15) Also, as shown in (b) of FIG. 6, there is no candle light blocking plate 15 between the two photosensitive elements 12 'and 13 installed therein, and a sufficient distance of verticality is provided so that all the light around the candles When it is detected and generates a melody, a space 16 'is formed on the ground of the candle 16 for easy radiation of sound, and as shown in FIG. 7, a protrusion 7 is formed on the bottom of the candle, and a small hole is formed at the lower peripheral side. 16 is a structure made by drilling a plurality of (not shown) 16 is a candle, 17 is a sound generating spurker.

If described in detail based on the working effect of the present invention configured as described above as follows.

Example 1

When the wick 9 is lit in a manner of directly sensing the temperature of the flame 5, the bimetal contact 4 directly contacting the flame by the temperature of the flame 5 of the wick 9 is "ON". The melody is generated by the operation of the melody IC by the circuit of FIG. 8 (a) or 8 (b).

Here, in the case of using the melody generating IC circuit of FIG. 8 (a), when the bimetal contact 4 shown in FIG. 2 is " OFF " The use of the diagram circuit is characterized in that the generation of the melody is stopped after the melody being played is completely finished even when the bimetal contact 4 is "OFF".

In addition, the circuit of FIG. 8 (a) has the advantage of long battery life since the power is turned “ON” and “OFF”, and the bimetal where the contact is “OFF” when the candle is lit is the same as the circuit of FIG. 8 (c). You can use

Claim 8 (a) Fig., The 8 (b) also R _l and R ₇ is R ₁ «R ₂ to be set to be the place 8 (c) in Fig _{R 1 »R 3, R 1 «R} 3 + R 4 in Set it.

Example 2

As shown in FIG. 3, the temperature of the flame 5 of the candle is directly sensed by the junction 8 of the thermocouple (two kinds of metal junctions) that generate thermal power. When the wick 9 is lit, the flame 5 is directly detected. When the contact point 8 of the thermocouple touches is heated, a thermoelectric Ve is generated (in the case of a CA material, a thermoelectric power of approximately Ve ≒ 0.25 to 0.3V is generated). As shown in FIG. If the thermal electromotive force because it is connected in series to each other while facing the same polarity so that the offset occurs in the polarity of voltage VR _1, as shown in V _l = ₁ VR V _l -Ve is decreased.

The decrease in V ₁ represents an increase in ΔV at V ₂ -V _l = ΔV, so pre-set ΔV (ie V ₁ and V ₂ ) such that ΔV ¹ = ΔV + Ve-> C when increasing ΔV to ΔV ¹ . Set to.

Where C is the minimum ΔV value required for the IC to operate.

For example, if C = 0.35V, when the light is not turned on, the value of ΔV is set to 0.25V and V _l and V ₂ are set. It's going to work.

Example 3

As shown in FIG. 5 (a) and FIG. 5 (b), the present embodiment detects the light of the candle 5, not the heat sensing method, and is installed inside the body of the photosensitive device 12 'in the candle. By remote sensing the light of the candle (5) inside the candle body as described with reference to Figure 5 (b) as follows.

As shown in FIG. 5 (b), when the wick 9 is lit, the light B enters the translucent candle body to reduce the resistance of the embedded CDS and the photosensitive device 12 '.

When using the first 10 degree circuits, "when referred to a resistance value at the time when it detects the light of the candle (5) R1 R ₁ 'the resistance of the CDS R ₁ when it is turned on, the candle (5) »R ₂ »R ₁ Set R _{2 as much} as possible. Also select the CDS type and R _{2 so} that "IC" will not work in natural light around the candle. If necessary, R ₂ can be configured to be used while adjusting the brightness of the surroundings. That is, the brighter the surroundings, the more R ₂ needs to be reduced. The biggest feature of the present embodiment is a very fast sensing characteristic which is immediately detected at the moment of ignition and a separate sensor at the wick 9 level ( 4) (8) (12) It is characterized by a simple configuration which does not require the connecting copper wire 2 and the pressure plate 6 or the like. Of course, the photosensitive element 12 may be provided around the flame 5 as shown in FIG. 5 (a).

In FIG. 10, when the light is turned off, the resistance of the CDS is sufficiently larger than R ₂ , but when the candle is turned on, the resistance of the CDS is sufficiently smaller than R ₂ so that the IC is operated.

Example 4

Similar to the third embodiment, the difference is that two photosensitive elements 12 'and 13 are provided inside as shown in FIG. 6 (a), and an opaque candle light blocking plate between the two photosensitive elements 12' and 13 is provided. (15) was formed.

In other words, the light (A) around the candle is detected in both CDS ₁ and CDS ₂ but the candle light (B) is detected only in the CDS ₁ , the CDS ₂ is installed so that the opaque blocking plate 15 is hardly detected Example 3 In order to eliminate the inconvenience of manually adjusting the R ₂ of FIG. 10 according to the ambient brightness at, the resistance value of the CDS ₂ decreases automatically when the surrounding light is the same as reducing the R ₂ in FIG. 10.

Here, as shown in FIG. 6 (b), the CDS ₁ is placed close to the candle, and the CDS ₂ is close to the candle, with a sufficient vertical distance without installing the opaque candle light blocking plate 15 between the two photosensitive elements 12 'and 13. that is to be installed away from the candle also claim 6 (a) If the peripheral to the Fig without giving the 10 degree R ₂ to manually adjust automatically according to the ambient illumination brighter, such as the resistance value of the CDS is reduced, so reducing the R ₂ Same thing.

The use circuit of this embodiment is the same as that of Fig. 11, and VR of Fig. 11 is a variable resistor for sensitivity minute adjustment.

Turning off the candle (RVR + RCDS) ₁ »RCDS turn on the _two or candle (RVR RCDS + ₁₎ to be «RCDS IC is operated.

In addition, in Example 3, an optical filter is formed by using a difference between a wavelength of a candle light and a wavelength of an ambient light source (fluorescent lamp). In addition to improving the effect even if installed on the horizontal plane of the) generated sound resonates between the bottom space (16 ') and the mounting surface of the candle (16) and escapes between the small hole (14) and the projection (7) It has the characteristic of delivering the same volume to people.

In addition, until now, only the embodiment of the melody generating circuit has been presented, but if necessary, it is possible to obtain an electric light effect through the control of the LED embedded in the surface of the candle. It is a practical design having an effect that can be widely used to enable it to operate when.
