BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a device for manufacturing a scented candle. More particularly, the present invention relates to a device for manufacturing a scented candle, the device enabling ordinary people to manufacture various scented candles easily.

Description of the Related Art

A candle is used to provide light and consists of a wick embedded in wax such as paraffin wax, soybean wax, and beeswax, which melts at a certain temperature and is molded in a combustible solid. In addition, a wax melt is a lump of solid wax with no wick.

A wax melt is made according to the same process as a candle: melting wax with hot water by using a double boiler method, pouring the melting wax into a container or a mold, and hardening the melting wax. However, a wax melt is used without burning a wick. The wax melt is put on the top of an aroma oil burner and heated by a tea light disposed at the bottom of the aroma oil burner, so that it is for enjoying fragrance produced as the wax melt melts. Fragrance oil (aroma compounds) is added in a paraffin wax, so that a conventional wax melt is mainly used for enjoying an imparted scent. In addition, a wick may be added to the wax melt, and a scented candle is popular in which the fragrance is produced while the wax melt is burned by lighting the wick.

Paraffin wax is a by-product of petroleum and a main material of the conventional wax melt and the scented candle. However, paraffin is known to release various toxic substances harmful to the human body, so that the use of paraffin is a contentious issue these days. In addition, odor, soot, and components of organic compounds are scattered to the air during combustion, leading to indoor air pollution and soil pollution when discarded.

Therefore, as environmental problems and well-being have become the concern of the public these days, paraffin wax used in conventional candles is replaced by soybean wax, which is a vegetable natural raw material, to solve environmental problems and health problems.

Using natural raw materials such as soybean wax and beeswax has merits in terms of health and environment, but maintaining the accurate temperature and the accurate ratio of oil for manufacture of scented candles is required, so that it is difficult for ordinary people to manufacture scented candles using natural raw materials.

In addition, the wax supplier110includes: a first inner container114where wax is accommodated; a first heater112provided outside the first inner container114; and a first temperature sensor113provided outside the first inner container114when the first inner container114is mounted in the wax and oil supply portion100. In addition, the oil supplier120includes: a second inner container124where oil is accommodated; a second heater122provided on the outside of the second inner container124when the second inner container12is mounted in the wax and oil supply portion100; and a second temperature sensor123provided outside the second inner container124.

Here, the first heater112and the second heater122may be embodied by a heating wire or a heating plate. Alternatively, the first heater112and the second heater122may be embodied by any one of various known technologies such as a surface heating element. In addition, the first heater112and the second heater122may be embodied by a heating device using an induction heating system, which is widely used. The first heater112and the second heater122respectively heat solid wax and oil provided in the first inner container114and the second inner container124, respectively. The first temperature sensor113and the second temperature sensor123respectively sense the first inner container114and the second inner container124heated by the first heater112and the second heater122, respectively, so that a controller210controls the temperature appropriately.

Here, the first inner container114and the second inner container124are detachable from the wax and oil supply portion100. Thus, the first inner container114and the second inner container124are stored in the wax and oil supply portion100at the time of use, and after manufacturing a scented candle, the first inner container114and the second inner container124are separated to wash out oil or wax contained therein so that the remainder of the wax and the fragrant oil are not left. The first inner container114and the second inner container124may be provided individually or integrally with each other.

The base300provided at the lower portion of the main body200is provided with a third heater310and a third temperature sensor340, wherein the third heater310heats the container400, and third temperature sensor340senses the temperature of the container400. Thus, wax and oil supplied to inside the container400are kept at a constant temperature and mixed in a stable state. The third heater310may also be embodied by a heating wire or a hot plate. Alternatively, the third heater310may be embodied by any one of various known technologies such as a surface heating element. In addition, the third heater310may be embodied by a heating device using an induction heating system, which is widely used.

A type of wax to be melted may be set by using a control switch260provided in the main body200. According to the set wax type, the controller210controls the first heater112to heat the first inner container114using a melting point of the temperature (hereinafter, referred to as melting temperature) of the wax stored in a memory240, and then the controller210controls the third heater310to heat the container400using a temperature (hereinafter, referred to as mixing temperature) stored in the memory240at which the wax and oil are mixed together. The controller210may include a processor such as an MCU and DSP and be implemented in a form of a computer program that is operated by the processor. That is, it is preferable that the memory240stores melting temperatures of various waxes and mixing temperatures in a table format.

Therefore, since the device for manufacturing a scented candle of the present invention mixes wax and oil at an accurate ratio and an accurate temperature, ordinary people can manufacture a high-quality scented candle.

The control switch260may be provided in the main body200or in the wax and oil supply portion100, although not illustrated in the drawings.

Wax is supplied as a cartridge contained a predetermined amount of solid wax, and oil is supplied as a capsule contained a predetermined amount of oil. Therefore, a user can adjust the ratio of wax and oil accurately without weighing the wax and the oil separately to adjust the ratio thereof.

For example, the wax is supplied as large, medium, and small cartridges, and the oil is supplied as a capsule contained a predetermined same amount of oil. In the case of using a small cartridge wax, three capsules of oil are used to mix with the wax. In the case of using a medium cartridge, five capsules of oil are used to mix with the wax, and in the case of using a large cartridge, seven capsules of oil are used to mix with the wax. In addition, various fragrance oils are used. Since each fragrance oil is supplied in a capsule, the user can mix various fragrance oils at an appropriate ratio to produce various fragrances. It is also possible to supply fragrant oil and wax in a single cartridge.

The capsule containing fragrance oil is configured to melt at a predetermined temperature such that the oil contained therein is discharged at the predetermined temperature. Accordingly, the controller210controls the temperature of the second heater122provided in the oil supplier120to supply the oil at the accurate mixing temperature. In other words, when the container400reaches the mixing temperature, the controller210controls the second heater122such that the oil is supplied to the container400from the second inner container124.

The device for manufacturing a scented candle of the present invention further includes: a second holding clip420holding one end of a wick410; and a first holding clip160into which the second holding clip420is inserted securely and which is connected to a lower surface of the wax and oil supply portion. Specifically, the first holding clip160preferably has a C-ring shape as illustrated inFIG. 6. The second holding clip420is made of a metal or synthetic resin having excellent elasticity and formed in a shape of a Christmas tree. In addition, the second holding clip420is configured to have a holding part422having a narrow waist to hold the wick410securely. The holding part422is inserted into the first holding clip160such that the first holding clip160is held by the wide width of an upper portion of the second holding clip420.

Here, a fixing member424using a sticker or an adhesive is provided at the opposite end of the wick410to firmly fix the wick410to an inner bottom surface of the container400.

The holding part422of the second holding clip420presses both sides of the wick410to hold the wick410. Thus, the user can adjust the holding position of the wick by pulling the wick410over a predetermined force.

The user fixes the wick410to the bottom surface of the container400using the fixing member424provided at the opposite end of the wick410. Then, the user allows the first holding clip160to hold the second holding clip420and adjusts the length of the wick410by pulling one end of the wick410held by the second holding clip420, so that the wick410is kept tense. Thus, the wick410can maintain the shape thereof while wax and oil are supplied.

Here, serrated protrusions (not illustrated) may be further formed on the holding part422of the second holding clip420. Accordingly, it is possible to adjust the length of the wick410easily by pulling only in one direction by the serrated protrusions.

A method of manufacturing a scented candle by using the device for manufacturing a scented candle of the present invention will be described. A cover130provided on the wax and oil supply portion100is opened to accommodate a wax cartridge selected by the user in the first inner container114and to accommodate an oil capsule selected by the user in the second inner container124, and then the cover130is closed.

Then, when the user sets the type of wax by adjusting the control switch260, the controller210receives information on an optimum melting temperature and mixing temperature of the selected wax, which is stored in the memory240, and controls the first heater112, the second heater122, and the third heater130.

Accordingly, the first heater112is maintained at an appropriate temperature under the control of the controller210so that the wax is stably melted. The melted wax is discharged through a first outlet116provided at a lower portion of the wax supplier110and is accommodated inside the container400.

Here, the first outlet116may be provided with an automatic valve to appropriately adjust the discharge amount of wax.

The controller210senses the temperature of the container400. When the temperature of the container400reaches the appropriate temperature for mixing the wax and the fragrance oil, the controller210controls the second heater122provided in the second inner container124to heat and melt the oil capsule, so that the oil inside the capsule is supplied to the container400through a second outlet126of the oil supplier120.

Here, the second outlet126may be provided with an automatic valve to appropriately adjust the discharge amount of oil. In addition, screw-shaped protrusions are formed on an inner circumferential surface of the container400. Accordingly, while the melted wax and the fragrance oil are supplied to the container400, the wax and the fragrance oil are rotated along the protrusions of the inner circumferential surface, so that the wax and the fragrance oil are mixed together in a more stable state.

As illustrated inFIG. 4, a stir rod150rotated by a motor140is provided on one side of the wax and oil supply portion100. The stir rod150is rotated under the control of the controller210to mix the oil and the wax thoroughly.

It is preferable that the stir rod150is made of silicone to prevent damage to the wax or oil and to prevent the release of endocrine disruptors, thereby preventing harmful effects on the user health.

Although not illustrated in the drawings, a vibrator may be provided inside the base300to facilitate mixing of the wax and oil contained in the container400by vibrating the container400.

Finally, after the oil and the wax are completely supplied to the container400, the operation of the third heater310of the base300is stopped to harden a scented candle.

Although not illustrated in the drawings, a proximity sensor may be provided at the base300. When the proximity sensor senses the movement of the container400or senses the movement near the container400, the operations of the first heater112, the second heater122, and the third heater130are stopped.

For example, when an infant or young child tries to hold the container400or the base300by hand, the controller210controls the first heater112, the second heater122, and the third heater130to turn off, so that it is possible to prevent the infant or young child from being burned due to the heat generated from the first heater112, the second heater122, and the third heater130.

Although not illustrated in the drawings, a weight sensor may be provided in the wax and oil supply portion100to sense the weight of the first inner container114and the second inner container124. In detail, the weight sensor senses the amount of wax and oil contained in the first inner container114and the second inner container124, respectively, so that it is possible to accurately sense the production status of the scented candle.

A display monitor250may be provided in the main body200or in the wax and oil supply portion100. The user can know the current temperature and the production state of the scented candle by means of the display monitor250, so that the time until completion of the manufacture can be checked. After the manufacture is completed, the controller210stops the operations of the first heater112, the second heater122, and the third heater130to prevent a fire or burn. Here, the display monitor250may be provided on the main body200or may be provided on the wax and oil supply portion100.

It is preferable that a communication device220is provided in the main body200. The communication device220is provided with a local wireless communication function such as Bluetooth, and is capable of communicating with a user terminal T such as a smartphone or a tablet computer.

Accordingly, the production state or the current temperature sensed by the controller210is transmitted to an external terminal so that the user can know the production state even when being a predetermined distance away and can control each part of the device for manufacturing a scented candle by means of the user terminal T.

That is, the user terminal T stops the operations of the first heater112, the second heater122, and the third heater130in an emergency situation, thereby preventing a fire or other danger. The user terminal T not only automatically sets the melting temperature and the mixing temperature of the wax whose type is set among the stored wax types by the control switch260, but also inputs information on additional types of waxes, and a melting temperature and a mixing temperature thereof through a user mode. In addition, the user terminal T instructs the pausing or stopping of the operation of the device for manufacturing a scented candle of the present invention through the control switch260. The user terminal T sets the melting temperature and the mixing temperature manually by rotating the control switch260of the main body200, as well as setting the wax type using the control switch260of the main body200.

A speaker230may be provided on the main body200such that the production state of the scented candle or the completion of the production is notified and warning of a fire or the like is promptly provided in an emergency situation.

Although not illustrated in the drawings, an overheat sensor may be provided in the main body200to sense the temperature of the first inner container114, the second inner container124, and the container400. When the overheat sensor senses overtemperature, the operations of the first heater112, the second heater122, and the third heater310are stopped to prevent a fire.

Although not illustrated in the drawings, a battery may be provided in the main body200or the base300. The device is charged with the power source when the external power exists and uses the power of the battery in the outdoors or in case of a power failure.

Although not illustrated in the drawings, a height adjustable structure may be applied to the main body200or the base300such that the user adjusts the height appropriately for ease of use.

According to the device for manufacturing a scented candle of the present invention, in addition to manufacturing a scented candle, it is possible to manufacture soap having various fragrances and colors by using wax and oil.

The memory240provided in the main body200stores a sentence or a word in a foreign language received from the user terminal T communicated through the communication device220.

Here, the main body200is provided with the proximity sensor (not illustrated) sensing an adjacent object using a laser, an ultrasonic wave, or the like. When the movement of a person or the like is sensed within a distance set by the controller210, the sentence or the word in the foreign language stored in the memory240is repeatedly output through the speaker230provided in the main body200.

Accordingly, the user can continuously learn the foreign language in an easy way by listening to the same sentence or word output from the speaker230repeatedly.

In addition, although not illustrated in the drawings, a microphone and a button may be provided in the main body200. When pressing the button, the microphone is operated to receive a sentence or a word in a foreign language which the user speaks and the sentence or the word is stored in the memory240.

Here, the controller210analyzes the contents spoken by the user and stored in the memory240and determines whether the analyzed contents and the contents output through the speaker230coincide with each other. When it is determined that the analyzed contents and the contents output through the speaker230coincide with each other, the user can see the interpretation of the sentence or the word in the foreign language by means of the user terminal T, and the controller210sends a signal to the user terminal T to allow the learning of the next step to proceed. Accordingly, the user can more easily study the foreign language.

Although not illustrated in the drawings, a fan may be provided to supply air to the container400. The memory240stores an optimal cooling temperature for hardening the wax mixed with oil. When the oil and wax contained in the wax supplier110and the oil supplier120are discharged, the controller210controls the fan to drive until the cooling temperature stored in the memory240and the temperature of the container400sensed by the third temperature sensor340coincide with each other.

In other words, the temperature sensed by the third temperature sensor340is compared with the cooling temperature. When the temperature of the container400is higher than the cooling temperature, the controller210controls the fan to operate to lower the temperature to the cooling temperature quickly.

When the temperature of the container400is the same as the cooling temperature, the controller210controls the fan to stop to keep the optimal temperature for hardening the wax, thereby preventing cracking in the scented candle.

According to the present invention, the device for manufacturing a scented candle includes: the wax supplier110containing and melting the solid wax; the oil supplier120supplying the oil containing the predetermined fragrance; the container400; and the controller210. When the user sets the type of wax to be used, it is possible to melt the wax at the optimum temperature automatically and sense the temperature of the melted wax to automatically mix the wax with the oil at the optimum temperature. Therefore, ordinary people can manufacture a high-quality scented candle with wax and oil.

According to the present invention, the wax and the fragrance oil are supplied in a form of a cartridge and a capsule having a predetermined amount, respectively, so that the wax and the oil can be supplied at an accurate ratio without need of weighing the wax and the oil. In addition, it is possible to manufacture a user's own unique fragrance by mixing different kinds of oils properly according to own taste.

According to the present invention, a communication device that enables short-range wireless communication such as Bluetooth is provided. Therefore, the communication device transmits the production state of the scented candle to the user terminal T to allow the user to monitor the production state. In addition, when using a new type wax, it is possible to control the temperature manually by means of the user terminal T, so that various types of waxes can be used to manufacture a scented candle.
