The heating device indirectly heats the aromatherapeutic particles of the herbal material contained in the medium, and achieves a constant temperature through self-heat-exchange of the medium while also liberates the aromatherapeutic elements. Thereby, the aromatherapeutic particles maintained with intact and complete structures are discharged outwards using heat circulation, and are released With stable amounts.

Description:
BACKGROUND OF THE INVENTION  
       [0001]     (a) Field of the Invention  
         [0002]     The invention relates to an application device for driving aromatherapeutic particles, and more particularly, to an application device for driving aromatherapeutic particles, in that the application device comprises a medium having a high evaporation temperature and indirectly activating aromatherapeutic particles, thereby disengaging and releasing aromatherapeutic particle having complete element structures with quantitative amounts.  
         [0003]     (b) Description of the Prior Art  
         [0004]     Prior indoor odor adjustment methods can be as simple as spraying liquid scent, or releasing essence contained in herbs by means of burning, so as to fill an environment with a pleasant smell. Recently, scented candles are burnt or essence oils are vaporized using heat to release aromatherapeutic particles and then fill an indoor environment for indoor odor adjustment, or to further obtaining sterilization effects using chemical functions thereof, or even to soothe and calm human sense organ nerves through biological functions thereof.  
         [0005]     Referring to  FIG. 1  showing an example of a scented candle, a scented candle  1  comprises aromatherapeutic elements  10 . When a flame  12  is formed by burning a pith  11 , the scented candle  1  is melted by a temperature of the flame  12  to simultaneously oxidize the aromatherapeutic elements  10 , which are then diffused into an indoor environment.  
         [0006]     Referring to  FIG. 2  showing a recent odor adjustment method using an essence, a pot  2  is placed with water  22  therein, and an aromatherapeutic essence film  20  provided at a water surface. The pot  2  has a bottom section thereof supported by a rack  21 . A flame  24  is formed within the rack  21  to boil the water  22 . Heat acquired by the water  22  is transmitted to the film  20  to further evaporate the film  20 .  
         [0007]     However, due to vigorous oxidation process imposed by burning of the flame  12 , compositions of the aromatherapeutic elements  10  contain in the scented candle  1  are frequently damaged. Hence, using the method of scented candles, scents spread out are often changed in addition to strong chemical smells. Also, humidity is increased because carbohydrates are formed accompanied with burning of the flame  12 .  
         [0008]     Again, regarding the aforesaid boiling method, the aromatherapeutic essence film  20  is floated on the surface of the water  22 , and the film  20  located at a corner  230  is likely to adhere to an inner surface  23  of the pot  2  due to heat transmission of the pot  2 . Furthermore, a level of the water  22  is lowered after a certain period of evaporation from boiling by heat transmission effects of the flame  24 , thus the aromatherapeutic essence film  20  at the corner  230  remains attached to the inner surface of the pot  2 . It is to be noted that a periphery of the pot  2  is given a same high temperature from heat transmission effects of the flame  24 , and therefore a temperature of the inner surface  23  is higher than that of the surface of the water  22 . As a result, high-temperature reactions are incurred at the aromatherapeutic essence film  20  to change scent structures of the aromatherapeutic essence film  20  or even scorch the aromatherapeutic essence film  20 .  
         [0009]     Apart from the aforesaid drawbacks, the prior method by boiling the water  22 , owing to being floated on the water surface, the aromatherapeutic essence film  20  is prone to direct and rapid evaporation from the water surface from boiling the water  22 , meaning that effective lifespan of the aromatherapeutic essence film  20  is reduced. Supposed the a large amount of essence is placed in the pot  2  to leave floating on the surface of the water  22 , the flame may directly burn the aromatherapeutic essence the water  22  when the water  22  is totally evaporated from heating by the flame  24 . When directly heated by the flame  24 , the aromatherapeutic essence is reacted with high temperatures to change structures of the aromatherapeutic particles therein and similarly producing particles with scorched or other discomforting smells.  
       SUMMARY OF THE INVENTION  
       [0010]     In view of numerous drawbacks of the prior invention, the primary object of the invention is to provide a novel application device for driving aromatherapeutic particles. The application device according to the invention, using an indirect activation method, comprises a medium material having a high evaporation temperature, wherein the medium is melted into a fluid when heated. After storing the heat, the heat energy is indirectly acted upon aromatherapeutic elements of an herbal material of an aromatherapeutic essence. For that the medium material is capable of temporarily containing the aromatherapeutic elements and is constantly heated, a self-circulation operation is formed using the heat, thereby gradually liberating the aromatherapeutic elements with stable amounts while also ensuring intact and complete structures of the aromatherapeutic elements.  
         [0011]     The other object of the invention is to provide an application device for driving aromatherapeutic particles, in that the application device comprises a temperature-constant heating device made of ceramic resistor heating plates having a positive temperature coefficient. The temperature-constant heating device is for ensuring a steady operating temperature and thus preventing different heat reactions of the aromatherapeutic particles, thereby maintaining intact and complete structures of the aromatherapeutic elements released with stable amounts.  
         [0012]     To better understand the invention, detailed descriptions shall be given with the accompanying drawings below.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0022]     Referring to  FIG. 3  showing an embodiment according to the invention, the invention comprises a wax medium  4  containing an aromatherapeutic element  3  to form a fragrance discharging body  30 . The wax medium  4  is a heat-fusing material, and becomes molten when accepting a heat temperature of 60 degrees Celsius. In addition, the wax medium  4  is held within a container  5  to acquire heat from externally applied heat waves  50  transmitted via the container  5 , and is filled with an herbal material  31  or infused with an aromatherapeutic essence  32 . The wax material  4  has an evaporation temperature of higher than 130 degrees Celsius, and usually accepts a temperature of around 80 degrees Celsius. Under circumstances of having a temperature of 80 degrees Celsius that is much less than the evaporation temperature, the heated medium  4  maintains structures thereof intact and undamaged, but only appears as a molten state. Furthermore, the medium  4  is constituted by mineral oils or natural oils, which provide affinity with the oil-like aromatherapeutic elements contained in the herbal material  31  or the aromatherapeutic essence  32 , and therefore oil-like aromatherapeutic elements or aromatherapeutic essence can be contained without any conflict.  
         [0023]     The medium  4  accepts temperatures ranging between  80  and  100  degrees Celsius, and is melted into a fluid at  60  degrees Celsius, which activates and liberates aromatherapeutic elements contained in the herbal material  31  or the aromatherapeutic essence  32 . Using energy generated by circulation of the fluid, the aromatherapeutic elements contained in the herbal material  31  are guided out, and become melted in the medium  4 . Thus, when the medium  4  is heated, apart from guiding out the aromatherapeutic elements in the herbal material  31  or liberating aromatherapeutic ingredients by reacting on the aromatherapeutic essence  32 , the aromatherapeutic particles at a lower section of the medium  4  are distributed to an upper surface of the medium  4  in an upward direction using the circulation and static energy caused by uneven heat from the heat waves  50  upon the container  5 .  
         [0024]     When being distributed at an uppermost section, the aromatherapeutic particles are similarly driven by the heat energy to remain uncontained in a liberated state to infuse into an indoor environment. Consequently, the aromatherapeutic elements in the herbal material  31  or the aromatherapeutic essence  32  are constantly activated to be mildly and gradually liberated.  
         [0025]     For that heat reaction temperatures range between 80 and 100 degrees Celsius, compositions of the aromatherapeutic element particles in the herbal material  31  and the aromatherapeutic essence  32  are allowed with intact and complete structures, thereby enabling the aromatherapeutic particles to approach 100% infusion capacity. According to the invention, smells of the aromatherapeutic elements are the same before and after being released, and amount thereof being released are maintained the same as well after smelling from distances nearby.  
         [0026]     Referring to  FIG. 4 , the wax medium  4  is a heat-fusing material, and thus becomes a fluid when melted using heat and stays in a solid state under room temperature (lower than a melting temperature thereof). When the wax medium  4  is under a molten stated when heated, the herbal material  31  or the aromatherapeutic essence  32  is filled therein so as to contain the herbal material  31  or the aromatherapeutic essence  32  in the medium  4 . When cooled by room temperature, a block-like, three-dimensional discharging body  300  is formed for facilitating packaging, storage or dividing into amounts as desired for application. Wherein, a shape of the block-like discharging body  300  can be animal designs or any other geometric three-dimensional shapes according to a user&#39;s requirements.  
         [0027]     Referring to  FIG. 5 , the aforesaid fragrance discharging body  30  or the block-like discharging body  300  accepts heat via a container  5 . The container  5  has an internal space for placing the fragrance discharging body  30  or the block-like discharging body  300 , and receives externally applied heat waves  50  transmitted from a temperature-constant heating device  6 . The temperature-constant heating device  6  comprises positive temperature coefficient ceramic resistor heating plates  63  for generating heat. The heating plates  63  have corresponding surfaces thereof devised with electrode plates  61  and  62  for conducting electricity, and are surrounded by a heat-conducting frame  64  for insulation. Heat generated from electricity conducted using resistance by the heating plates  63  is indirectly transmitted to the container  5  via the heat-conducting frame  64 , and the acting heat waves  50  then enter into the container  5  to act upon the discharging body  30  or the block-like discharging body  300 . Hence, the medium  4  of the discharging body  30  is melted by the heat, such that the aromatherapeutic elements of the herbal material  31  and the aromatherapeutic essence  32  become circulated as shown in  FIG. 3 , and are liberated outwards using flowing effects thereof.  
         [0028]     To avoid an inner surface  53  of the container from adhering to any undesired substances, the inner surface  53  is provided as a smooth surface that facilitates the oils coming off. In addition, for protection purposes, an upper opening of the container  5  is devised with a protective cover  51 , which has ventilation openings  510  for discharging internal aromatherapeutic air.  
         [0029]     The temperature-constant heating device  6  operating based on electricity adopts a power-selective switch  65  for adjusting magnitudes of power, so as to change temperatures of heating device  6 . Temperatures of the heating device  6  are modulated according to temperature requirements for evaporating different aromatherapeutic elements. For instance, an activation temperature of the aromatherapeutic essence  32  is lower than that of the herbal material  31 , thus a temperature for activating the aromatherapeutic essence  32  can be controlled at a lowest temperature possible. However, since it is necessary that the herbal material  31  be heated again to perform depth induction of arormatherapeutic compositions contained therein, higher temperatures are utilized for completing such induction. Or, for ligneous plants, higher power is even needed to guide out the aromatherapeutic particles within the ligneous fiber tissues. Therefore, the design of the power-selective switch  65  provides solutions corresponding to requirements regarding heat needed for liberating different aromatherapeutic elements  3 ; however, a highest temperature is to be maintained below the evaporation temperature of the medium  4 .  
         [0030]     The ceramic resistor heating plates  63  are made of ceramic resistors having a positive temperature coefficient, and are characterized as capable of generating expected temperatures according to hardware specifications. Moreover, the ceramic resistor heating plates  63  have a self-controlled temperature heating property, and thus a temperature obtained by the medium  4  stays at a constant temperature for providing the aromatherapeutic elements  3  with steady effects, thereby inducing and liberating the aromatherapeutic particles with stable amounts as well as preventing undesired reactions caused by fluctuating temperatures upon the medium  4 .  
         [0031]     Referring to  FIG. 6 , when being heated by the heat waves  50 , the container  5  is provided with a temperature sufficient for melting the medium  4  therein. The medium  4  is then enabled to release and induce the aromatherapeutic particles of the herbal material  31 .  
         [0032]     The invention may also further utilize a filter net  52  having an accommodating space for holding the herbal material  31 , such that the herbal material  31  is dipped in the medium  4  in a suspended manner. When the medium  4  is heated and the aromatherapeutic elements in the herbal material  31  are completely released, residues of the herbal material  31  are taken out and a new herbal material is replaced therein. For that surfaces of the residual herbal material are attached with the wax medium  4 , the residual herbal material can serve purposes as tinder for igniting flames to avoid environmental pollution. Or, the herbal material  31  can be long-term decorative objects by attaching the wax medium  4  according to shapes and appearances thereof.  
         [0033]     Referring to  FIG. 7 , when the container  5  is heated by the heat waves  50  for melting the medium  4 , the medium  4  becomes a fluid in the container  5 . In order to provide long-lasting fragrant effects, an intermittent supply device  7  is used for intermittently refilling the aromatherapeutic essence  32 . Through the intermittent supply device  7 , the aromatherapeutic essence  32  may be refilled by dripping or other electromechanical control methods, such that the aromatherapeutic essence  32  is quantitatively and periodically supplied for giving aromatherapeutic particles further to be released by the medium  4 . The evaporation temperature of the medium  4  is much higher than the evaporation temperature of the aromatherapeutic essence  32  and the temperature of the heat waves  50 , and hence the medium  4  remains at a melted stated without being evaporated over a long period of time. Consequently, each drop of the aromatherapeutic essence  32  refilled is ensured to undergo heat reaction with a same volume of the medium  4 , thereby discharging aromatherapeutic elements having intact structures with stable amounts. The embodiment shown in  FIG. 7  can be applied to environments that need long-lasting fragrant effects - a lavatory or a bathroom for instance.  
         [0034]     Referring to  FIG. 8 , an upper opening of the container  5  is devised as a cone shape having a dilated upper section and a contracted lower section, so as to provide the discharging body  30  with cooling effects using room temperature when placed therein, and to facilitate the discharging body  30  to disengage from the container  5  when cooled down to a block-like body.  
         [0035]     Referring to  FIG. 9 , an inner surface of the container  5  is devised as an arched surface. When the discharging body is cooled by room temperature, a force F is imposed from an edge upon the discharging body to form an angle θ, such that the block-like discharging body  300  is likely disengaged from the container  5 . The inner surface of the container  5  is also devised as a smooth surface that easily detaches from oils for facilitating disengagement of the discharging body  300 , and can be accomplished by applying glaze or Teflon. In addition, the container  5  is preferably made of a heat-conductive material.  
         [0036]     It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
