It should be interpreted as meaning and concept corresponding to the technical idea of the present invention.

Hereinafter, a self-powered apparatus using a candle according to the first embodiment of the present invention (hereinafter, referred to as a "self-powered apparatus") will be described with reference to FIGS. 2 to 7B.

The self-power generation device converts the heat energy generated from the flame into electrical energy while the candle is burned, but has a technical feature to increase the convenience of candle extinguishing work by adjusting the oxygen inflow into the candle and to manually operate each part.

Accordingly, it is possible to increase the convenience of the candle fire extinguishing operation, and by performing the manual operation of the parts, it is possible to increase the efficiency of the self-generation since no power consumption occurs during the self-generation.

As shown in FIGS. 2 and 3, the self-generating device includes a base 100, a head part 200, a power generation part 300, and a fire extinguishing cap 400.

The base 100 constitutes a lower portion of the self-generating device and is supported on the ground.

Base 100 is formed to have a flat bottom, its shape is not limited to a particular shape.

In the center of the base 100, a fixing groove 110 for fixing the candle is formed.

In this case, the candle refers to both a general candle that emits only light while burning, and a candle that emits incense.

On the other hand, the base 100 is preferably provided with a charging terminal that can use the power generated from the power generation unit 300.

At this time, the amount of power generated through the power generation unit is about 5W, considering the small capacity, it can be understood that the type of electronic devices that can be charged and used through the charging terminal is limited.

Next, the head portion 200 constitutes an upper portion of the self-generating device, the light source is preferably installed inside.

The light source serves to emit light using the thermoelectric power produced by the power generation unit 300.

As a light source, it is preferable to use a light emitting diode (LED) having high light efficiency, but various light sources having high light efficiency may be used.

The head 200 is fixed on the heat sink of the power generation unit 300 to be described later.

Next, the power generation unit 300 is a configuration for producing electricity by using the heat energy of the candle, is installed in the lower portion of the head portion 200.

The power generation unit 300 uses a thermoelectric element 310 that generates electricity by an effect of Thomas johann seebeck, which is a phenomenon in which electromotive force is generated due to a temperature difference between both ends, and a contact surface and a heat sink of the heat absorbing plate 320 are used. Thermoelectric power is generated by using a temperature difference between the contact surfaces with 330.

That is, one side of the thermoelectric element 310 may be heated in high temperature by receiving heat absorbed by the heat absorbing plate 320 by surface contact with the heat absorbing plate 320, and the other side of the thermoelectric element 310 may be a heat sink 330. By transmitting heat to the heat sink 330 in contact with the surface, it can be cooled to low temperatures, such a temperature difference occurs on one side and the other side of the thermoelectric element 310, the thermoelectric element 310 has a Seebeck effect By generating thermoelectric power through it can produce electricity.

On the other hand, the power generation unit 300 is installed on the base 100 through the support (500).

Support 500 is installed between the power generation unit 300 and the support 500 as shown in Figure 2, and has a technical feature configured to be made to adjust the length.

That is, since the flame position of the candle is lowered as the candle is burned, the position of the power generation unit 300 should also be lowered along the flame of the candle, between the power generation unit 300 and the candle by adjusting the length of the support 500. This is to keep the space between them.

The support 500 is composed of a first support 510 and a second support 520 as shown in FIG.

The first support 510 extends downward from both sides of the heat sink 330 constituting the power generation unit 300, and a fixing hole 511 is formed at an end thereof.

The second support 520 is installed upward from the base 100 and forms an insertion groove 521 to allow the first support 510 to be inserted therein.

At this time, the second support 520 is formed with a plurality of height adjustment holes 521 in the height direction.

The height adjusting hole 521 corresponds to the fixing hole 511, the length of the entire support 500 is adjusted according to the position corresponding to the fixing hole 511.

At this time, the fixing pin 530 for restraining the length of the support 500 is provided.

That is, the fixing pin 530 passes through the height adjusting hole 521 of the second support 520 and the fixing hole 511 of the first support 510, so that the support 500 can maintain the length of the state. It is.

As can be seen through this, the distance between the candle and the power generation unit 300 is made by hand by adjusting the length of the support 500, so that no electrical energy consumption occurs.

Accordingly, it is possible to increase the efficiency for self-power generation.

Next, the digestion cap 400 collects the heat energy of the candle and efficiently serves the power generation unit 300, and serves to easily extinguish the candle.

Digestion cap 400 is coupled to the lower portion of the power generation unit 300, is formed to have a form of expansion toward the candle.

Fire extinguishing cap 400 is configured to be elevated based on the power generation unit (300).

Fire extinguishing cap 400 is configured to be elevated through the lifting means 410, as shown in Figure 4 is composed of a pair.

For convenience of description, a pair of fire extinguishing caps 400 will be referred to as a first fire extinguishing cover 420 and a second fire extinguishing cover 430.

The first fire extinguishing cover 420 is coupled to the lower portion of the power generation unit 300 through the lifting means 410, and includes a fixed flange 421.

The elevating means 410 is composed of a coupling portion 411 installed on the lower portion of the power generation unit 300 and a screw portion 412 provided on the first fire cover (420).

At this time, the coupling part 411 is made in the form of a hollow pipe so that the heat energy of the candle can be transferred to the heat absorbing plate 320 of the power generation unit 300, and forms a male thread.

In addition, the screw portion 412 of the first fire-extinguishing cover 420 is formed in the form of a hollow pipe for screwing the coupling portion 411, and forms a female screw thread for coupling the male screw thread.

As such, the threaded portion 412 of the first fire extinguishing cover 420 is screwed to the coupling portion 411, so that the first fire extinguishing cover 420 may be lifted or lowered while the thread is loosened or tightened through the rotation of the threaded portion 411. You have a configuration.

The fixing flange 421 is configured to cover the candle, it is made radially downward from the screw portion 412.

As the fixed flange 421 is made in a radial manner as described above, the heat energy of the candle may be collected and transferred to the power generation unit 300, thereby increasing power generation efficiency.

In this case, a plurality of through holes are formed in the fixed flange 421, which is referred to as a first through hole 421a.

The first through hole 421a is configured to supply oxygen smoothly to the candle inside the first fire cover 420.

The second fire cover 430 serves to open and close the first through hole 421a of the first fire cover 420 and overlaps the upper portion of the first fire cover 420.

At this time, since the second fire cover 430 is simply seated on the first fire cover 420, it is free to rotate.

The second fire extinguishing cover 430 includes a rotation flange 431 corresponding to the fixed flange 421 of the first fire cover 420, and the rotation flange 431 corresponds to the first through hole 421a. Two through holes 431a are formed.

By such a configuration, the rotation flange 431 of the second fire cover 430 is to open or close the first through hole (421a) while being rotated on the fixed flange 421 of the first fire cover (420).

When the first through-hole 421a is open, since the oxygen can be introduced into the first fire cover 420, the candle can be burned smoothly, and when the first through-hole 421a is closed, the first fire cover Since the inflow of oxygen is not made to the inside of the 420, the candle is gradually digested.

On the other hand, the lifting means 410 is a configuration for lifting the digestion cap 400, it is possible to configure the lifting of the fire extinguishing cap 400 through the screw coupling as described above, as shown in Figure 6 It can also be configured using the member 413.

The stretchable member 413 is preferably made of a material of a characteristic that the shape is not restored to its original state when a force is arbitrarily applied.

This is because the user must manually adjust the position of the power generation unit 300, when the power generation unit 300 is arbitrarily lowered, the position of the power generation unit 300 should be able to stay in the lowered position.

At this time, the configuration of the elastic member 413 may be applied in various ways, it is preferable that the present invention is provided with a corrugated pipe.

The corrugated pipe 413 is a member that can easily lift the power generating unit 300 manually as an elastic member commonly referred to as 'Java'.

Hereinafter, the operation of the self-generating device having the above configuration will be described.

The candle is inserted into the fixing groove 110 of the base 100.

At this time, when the upper end of the candle interferes with the fire cap 400, the screw 412 of the first fire cover 420 to raise the fire cap 400, or the lifting means 410 corrugated pipe 413 ) In the case of raising only the digestion cap (400).

Then, after ignition on the wick of the candle, by rotating the screw 412 of the first fire cover 420 to lower or lower the lifting means 410 is a corrugated pipe pull the fire extinguishing cap 400 to the fixed flange 421 To cover part of the candle.

In this case, as shown in FIG. 7A, it is understood that the first through hole 421a should be open in correspondence with the second through hole 431a.

Then, while the candle is burned, the heat energy of the candle is transmitted to the heat absorbing plate 320 of the power generation unit 300 through the pipe of the screw part 412 and the coupling part 411 to heat the thermoelectric element 310, and the heat sink ( As the heat of the thermoelectric element 310 is cooled through the 330, electricity is produced by the Seebeck effect according to the temperature difference.

Although not shown, the electricity produced as described above may emit a light source of the head 200 through a circuit configuration, and may supply power to the electronic device through a charging terminal provided in the base 100.

On the other hand, as the candle is burned, the flame position of the candle is lowered, and the user keeps the interval between the power generation unit 300 and the candle constant so that the flame of the candle does not move away from the power generation unit 300.

To this end, the fixing pin 530 of the support 500 is removed to insert the first support 510 deeper into the second support 520.

Accordingly, the entire length of the support 500 is reduced, so that the distance between the power generation unit 300 and the candle can be maintained.

At this time, the fixing hole 511 of the first support 510 and the height adjustment hole 521 of the second support 520 should correspond to each other.

Thereafter, the fixing pin 530 is inserted through the height adjusting hole 521 and the fixing hole 511 so that the length of the entire supporter 500 is fixed.

On the other hand, in order to stop the self-generation process, the candle is extinguished.

To this end, the rotation flange 431 of the second fire cover 430 is rotated to close the first through hole 421a as shown in FIG. 7B.

Accordingly, since the amount of oxygen in the digestion cap 400 is gradually reduced, the candle is also gradually digested.

This stops the self-development process.

Then, in order to resume self-power generation, by rotating the rotary flange 431 of the second fire extinguishing cover 430 to open the first through-hole (421a), by raising and lowering the fire extinguishing cap 400 using the lifting means 410 Expose the top of the candle.

That is, the rotation of the coupling portion 411 and the screw portion 412 or shrink the corrugated pipe 413 to raise the position of the fire cap (400).

Next, after igniting the candle, the fire cap 400 is lowered again to allow the first fire cover 420 to cover the candle and resume self-power generation.

On the other hand, the cooling means may be further provided to further increase the cooling efficiency of the heat sink of the self-powered device using the above-described candles.

The thermoelectric element for electricity production increases the efficiency of electricity production as the temperature difference increases. If there is a limit in raising the temperature of the candle, which is a heat source, the cooling means is installed on the heat sink to increase the cooling efficiency of the heat sink to increase the temperature difference of the thermoelectric element. You can increase the efficiency.

It is formed to discharge the heat collected in the outside.

In addition, the suction fan 622 is installed at a position corresponding to the heat sink 330, and the wing direction of the suction fan 622 is formed to allow the outside air to be sucked into the heat sink 330 when power of the motor 610 is generated.

Accordingly, as shown in FIGS. 9 and 10, the suction fan 622 is integrally formed at both sides of the discharge fan 621, and its wings are formed opposite to the wing direction of the discharge fan 621.

Through such a configuration, even when the discharge fan 621 and the suction fan 622 are rotated at the same time when the power of the motor 610 is generated, the movement of the airflow is in the opposite direction.

On the other hand, the partition 623 is preferably installed between the discharge fan 621 and the suction fan 622.

The partition 623 serves to partition the warmth of the heat absorbing plate 320 discharged from the outside air sucked in.

As shown in FIG. 10, the partition wall 623 may be formed higher than the height of the discharge fan 621 and the suction fan 622.

Next, the wind direction guide 630 fixes the fan 620 to the heat sink 330, and serves to guide the warm air discharged and the outside air sucked in.

The wind direction guide 630 is preferably screwed to the heat sink 330, the assembly means is not particularly limited.

As illustrated in FIG. 11, the wind direction guide 630 forms discharge holes 631 corresponding to the discharge fan 621 and suction holes 632 corresponding to the suction fan 622.

That is, the heat conductor 340 installed on the heat absorbing plate 320 is made of a pipe shape in which the fruit oil is accommodated. The contact portion 341 inserted between the heat absorbing fins of the heat absorbing plate 320 and in close contact with the heat absorbing plate 320 and the spiral portion 342 extending downward from the close contact portion 341 to correspond to the flame of the candle. It is composed.

That is, by such a configuration, the flame of the candle heats the spiral portion 342, and the temperature of the fruit oil inside the heated spiral portion 342 is transmitted to the heat absorbing plate 320 without heat loss, thereby absorbing the heat absorbing plate 320. ), The temperature of one surface of the thermoelectric element 310 can be further increased.

On the other hand, the heat conduction plate 330 is also provided with a heat conductor 340 to increase the heat dissipation effect.

The heat conductor 340 installed on the heat sink 330 accommodates refrigerant oil instead of fruit oil.

That is, the refrigerant oil increases the cooling efficiency of the heat sink 330, and maximizes the cooling efficiency of the heat sink 330 together with the cooling means 600 provided above the heat sink 330.

At this time, the heat conductor 340 installed on the heat sink 330 does not protrude outward from the spiral to avoid interference with the cooling means 600 above.

That is, as shown in Figure 18, the thermal conductor 340 is installed between the heat radiation fins constituting the heat sink 330.

In this case, an insertion groove is formed between the heat dissipation fins so as to avoid interference with the heat conductor 340 and to allow the heat conductor 340 to be fitted.

As described above, since the heat conductor 340 including the fruit oil and the refrigerant oil is further provided in addition to the configurations of the heat absorbing plate 320 and the heat sink 330, the temperature difference of the thermoelectric element 310 occurs even more. Electricity production efficiency can be maximized.
