Description

  The present invention relates to a portable fragrance generator capable of releasing a fragrance mainly for aromatherapy.

  A device for aromatherapy has been developed (see, for example, Patent Document 1). As shown in FIG. 17, this aromatherapy device 80 has a structure in which the outer shape of the case member 81 is spherical and the fragrance is heated by the heat of the bath. With this structure, there is a problem that the outer shape is enlarged and the thickness is particularly increased. Moreover, since it is the structure which heats a fragrance | flavor with the heat of a bath and emits a fragrance, it cannot utilize in normal rooms other than a bath.

  On the other hand, an aromatherapy device that includes a heating source and can be used indoors has also been developed (see, for example, Patent Document 2). As shown in FIG. 18, the aromatherapy device 84 includes a container 85 for containing a material to be heated, a heating plate 86 disposed below the container 85, and a heater 87 for heating the heating plate 86. This aromatherapy device also has the disadvantage that it has a relatively large external shape and lacks compactness.

  Furthermore, these aromatherapy devices are not preferable for the environment because they do not have a structure for replacing batteries and are disposable. In particular, due to the recent increase in environmental awareness, there is a demand for a reusable structure, but such an aroma generator has not yet been developed.

  For example, the above-described aromatherapy device cannot maintain a waterproof structure when disassembled for battery replacement. For this reason, if it is continuously used, there is a possibility of a safety problem. In recent years, lithium-ion secondary batteries with higher output are often used as built-in batteries. However, lithium-ion secondary batteries hate moisture, so the conventional structure could not cope with them in terms of safety. .

  Further, as shown in FIG. 8, the third case 2C is detachably attached to the lower surface of the case 2 in a screw-in manner. For this reason, as shown in the sectional view of FIG. 7, the third case 2C is provided with a thread on the inner surface of the upper end. Similarly, the locking piece of the first case 2A also has a thread that meshes with this thread on the outer surface of the lower end. The second sealing material 9 is disposed on the outer surface of the locking piece and the inner surface of the third case 2C, so that the waterproofness after mounting is maintained while being detachable. In this way, by pressing the ring plate reliably with the screwing mechanism and rotating the third case 2C and screwing it in, the waterproof structure can be exhibited respectively, thereby realizing a double waterproof structure, Waterproofness is reliably maintained.

  As shown in FIG. 10, the bottom surface of the third case 2 </ b> C, that is, the bottom surface of the second cover 67, forms a portion where the power receiving coil 33 is located in a substantially flat shape 67 a. And the receiving coil 33 is arrange | positioned inside this 2nd cover 67 in this planar area | region 67a. With such an arrangement, the power receiving coil 33 can be disposed at the bottom surface inside the case 2, in other words, at a position closest to the charging stand 40, and the distance between the power receiving coil 33 and the power transmitting coil 41 can be shortened to improve the coupling efficiency. It becomes possible to raise.

Further, the fact that the bottom surface of the case 2 is flat is advantageous in that it is stable when the fragrance generating device 100 is placed. In particular, the third case 2C (second cover 67) formed in a dome shape has a flat portion at the center of the third case 2C inevitably by making the apex portion of the dome flat. Therefore, the receiving coil 33 is disposed here, and the secondary battery 1 is further disposed thereon, so that the fragrance generating device 100 can be mounted on the mounting table 43 of the charging table 40 stably in terms of the center of gravity. The power receiving coil 33 is covered with a coil cover 54 via a shield 53.
(Third waterproof structure)

Further, as a third waterproof structure for providing a waterproof structure to the battery storage space BS, a third seal member 52 is disposed between the battery lid 51 and the second case 2B. In order to sandwich the third sealing material 52 between the battery lid 51 and the second case 2B, a flat surface is provided near the periphery of the lower surface of the second case 2B, while on the other hand, A hook-shaped holding surface is formed so as to face the two cases 2B flatly. As a result, the battery storage space BS that is assumed to be opened for battery replacement can secure a wide contact area by the third sealing member 52 having a sandwiching surface as a flat plate, and can maintain waterproofness even after repeated use. .
(Third sealing material 52)

  A third seal member 52 is provided as a third waterproof structure for making the battery housing space BS waterproof. The third sealing material 52 is made of an elastic material, and is disposed between the battery lid 51 and the second case 2B. The third sealing member 52 has a flat plate shape that is sandwiched between the battery lid 51 and the second case 2B. As a result, the battery storage space BS that is assumed to be opened for battery replacement can secure a wide contact area by the third sealing member 52 having a sandwiching surface as a flat plate, and can maintain waterproofness even after repeated use. .

  The third sealing material 52 is a ring plate made of a ring-shaped elastic material. Further, if necessary, a convex shape or a concave shape can be provided on the substantially flat surface to enhance the sealing performance. As described above, the battery lid 51 can be removed to replace the secondary battery 1 with the third case 2C removed. While making such a battery lid 51 detachable, a waterproof structure is adopted so that water does not enter the battery storage space BS inside the battery lid 51 during use. Here, the risk of flooding by adopting different connection structures is reduced by dividing the attachment / detachment of the third case 2C and the attachment / detachment of the battery lid 51 into the screw-in type and the screwing. Furthermore, the screw-type third case 2C is waterproofed with an O-ring, and the battery lid 51 fixed with screws is a plate-shaped ring plate instead of an O-ring as shown in FIG. The insulating reliability can be improved by bringing the ring plate and the battery lid 51 into contact with each other.

  Thus, in addition to the structure which seals the fitting surface of 1st case 2A and 3rd case 2C only by 2nd O-ring, by providing 1st O-ring and a ring board, 3rd case temporarily A double waterproof structure that can be protected from flooding is realized even if it is flooded. That is, while the second O-ring prevents water from entering the circuit board, the ring plate can prevent water from entering the secondary battery 1. Furthermore, the O-ring that is the fourth seal material 55 can prevent water from entering from a gap between a lamp reader 60 and a battery lid 51, which will be described later. On the other hand, on the upper surface of the case 2, the oil tray portion 4 and the first case 2A seal the fitting surface by insert molding. By realizing the waterproof function with such a structure, it is possible to prevent moisture from entering the fragrance generating apparatus 100 and to obtain a highly reliable fragrance generating apparatus 100.

By providing the waterproof function, it is possible to prevent moisture from entering the fragrance generating device 100 and use it stably. It can also be washed with water. In particular, while the third case 2C is detachable and the secondary battery 1 is replaceable, the second waterproof structure can prevent water from entering the second storage space SP2 during normal use, and thus can be washed with water. In addition, electronic components such as the charging circuit 35 incorporated in the first storage space SP1 can be protected from flooding by the independent first waterproof structure, and the life and reliability of the device can be improved. Further, by making it possible to wash with water, it is easy to clean and care for the oil tray portion 4 storing the fragrance, and it is possible to obtain an advantage that it is easy to maintain clean.
(Circuit board 7)

The circuit board 7 is a donut-shaped flat plate, and the heating means 3 is disposed in the central opening. The heating means 3 is the PTC heater 3A as described above. Further, as shown in FIG. 4, a light emitter 15, a temperature sensor, and the like are mounted on the circuit board 7. The light emitter 15 is mounted on the back side of the circuit board 7 as shown in the cross-sectional views of FIGS. An LED or the like can be used for the light emitter 15. The light from the light emitter 15 illuminates the translucent second cover 67 through the lamp reader 60. Further, a thermistor or the like can be used as the temperature sensor, and the temperature of the oil tray unit 4 heated by the heating unit 3 is detected and sent to the control unit 6. On the circuit board 7, a charging circuit 35 for the secondary battery 1 is also mounted in addition to the heating circuit 3 and the driving circuit for the light emitter 15.
(Lamp reader 60)

  A lamp reader 60 is also disposed between the shield 53 and the coil cover 54. The coil cover forms a slit for inserting the lamp reader 60. The lamp reader 60 is a member that guides the light of the light emitter 15 mounted on the back surface (lower side in FIG. 4) of the circuit board 7 to the second cover 67 of the third case 2C. A configuration in which the lamp reader 60 efficiently guides the light from the light emitter 15 to the second cover 67 and efficiently emits light from the entire second cover 67 will be described with reference to FIGS. 10 and 11. As described above, the LED cannot be mounted at the center of the circuit board 7 due to the fact that the secondary battery 1 is disposed at the approximate center inside the case 2. This is because the secondary battery 1 interposed between the circuit board 7 and the third case 2C is obstructed and cannot guide light. Therefore, the LED mounted on the side surface of the secondary battery 1 is reflected twice and guided to the lower surface of the secondary battery 1 so as to bypass the secondary battery 1. For this reason, the lamp reader 60 has a shape bent twice in an L shape. Specifically, the light incident part 61 is connected to one end of the light guide part 62 at a right angle, and the light output part 63 is connected to the other end at a right angle opposite to the light incident part 61. The lamp reader 60 is made of a translucent acrylic plate or the like. The incident surface 61a that is the end surface on the light incident portion 61 side of the lamp reader 60 faces the LED disposed on the side surface of the secondary battery 1, and the emission surface 63a that is the end surface of the light emitting portion 63 is the third case. 2C is arranged so as to face almost the center of 2C. Further, in the center of the third case 2C, light that is incident vertically on the position facing the emission surface 63a is not transmitted, but is guided in the horizontal direction, that is, along the wall surface of the third case 2C. A gate portion 67b for reflecting the light is formed. The gate portion 67b is formed in a truncated cone shape, and includes an inclined surface that is inclined at about 45 ° in a sectional view. Further, the second cover 67 is subjected to light emission processing such as blasting or dispersion of the diffusing material so that the light guided as described above is diffusely reflected to emit light as a whole. Accordingly, when the LED is caused to emit light, the light introduced from the incident surface 61a of the lamp reader 60 is reflected twice by the bent portion and emitted from the center of the third case 2C. Then, the light is dispersed by the gate portion 67 b provided on the translucent second cover 67, and the light of the LED is efficiently guided to the entire circumference of the second cover 67.

  The exit surface 63a of the lamp reader 60 penetrates the power receiving coil 33 as shown in FIG. Since the power receiving coil 33 has an air core, the center is opened. By using this, by inserting the exit surface 63a of the lamp reader 60, the power receiving coil 33 is positioned on the bottom surface of the case 2 to improve the coupling efficiency during charging, and light is guided to the center of the case 2. The structure that causes the case 2 to emit light can be compatible.

In addition, the lamp reader 60 shown in FIG. 11 has a staircase that reflects the reflection surface 64 at the orthogonal portion between the light guide unit 62 and the light output unit 63 while making the width of the light guide unit 62 smaller than the width of the light output unit 63. It is in the shape. It is desirable that the light guide portion 62 be made as thin as possible for the convenience of being arranged between the secondary battery 1 and the third case 2C, that is, in the thickness direction of the case 2. On the other hand, in order to efficiently emit light and guide it to the third case 2C, it is preferable that the emission surface 63a be wide. For this reason, the thickness of the light emission part 63 is made thicker than the light guide part 62. On the other hand, even in the reflection surface 64 having different thicknesses, the inclined surface is not a flat shape but a step shape so that light can be uniformly reflected and guided as shown in FIG. Accordingly, there is an advantage that the light can be efficiently reflected uniformly on the thick light output portion 63 while the thickness of the light guide portion 62 is reduced.
(Second cover 67)

  The second cover 67 has a light guide property by blasting a transparent resin. Thereby, the light emission of the light-emitting body 15 can be guided, and the whole can be made to shine.

Next, a circuit diagram of the fragrance generating apparatus 100 is shown in FIG. The fragrance generating apparatus 100 in this circuit diagram includes a temperature control circuit 92 that controls electric power supplied from a rectangular secondary battery that is a secondary battery 1 to a planar PTC heater 3A that is a heating means 3. FIG. 12 shows a temperature pattern in which the temperature control circuit 92 controls the temperature of the oil tray section 4 that is the heating means 3. The temperature control circuit 92 stores the first set temperature and the second set temperature in the storage unit 13 in order to heat the heating unit 3 with the temperature pattern shown in these drawings. The control part 6 which controls the temperature of the heating means 3 to the 1st preset temperature and the 2nd preset temperature is provided.
(Temperature pattern)

  As shown in FIG. 12, the controller 6 controls ON / OFF of the heating unit 3 so as to alternately repeat a predetermined ON time and a predetermined OFF time. Specifically, the first set temperature, which is the lowest temperature at which a scent is felt, is maintained for a first set time, and then a scent with a sufficient concentration at which the scent can be clearly felt is higher than the first set temperature. A possible second set temperature is maintained for a second set time (preferably shorter than the first set time) and this is repeated. These set temperatures and set times are determined by the type of aroma oil used. In the example of FIG. 12, the first set temperature is set to 35 ° C., the second set temperature is set to 50 ° C., the first set time is set to 15 minutes, and the second set time is set to 30 minutes. Not.

  By setting it as such, it is possible to continuously enjoy the fragrance while considering olfactory fatigue, and the aromatherapy effect can be maintained. Even if the aroma oil is volatilized at a constant temperature, the human sense of smell immediately gets used to the scent. Also, if you raise the temperature more than necessary to emphasize the scent, you will experience olfactory fatigue. Therefore, a temperature profile that takes into account olfactory fatigue is adopted, and the temperature is lowered to the lowest temperature at which the fragrance is felt at regular intervals, and then the fluctuation is given to raise the temperature. As a result, fragrance with a concentration that makes the odor clearly appear appears at regular intervals, and by weakening the fragrance, it avoids olfactory habituation and lowers it to a limit temperature that does not make the odor feel, and there is no odor at all By not creating a state, user dissatisfaction can be avoided.

  The storage unit 13 stores a temperature pattern including the first set temperature and the second set temperature. Since the temperature pattern of FIG. 12 repeats the first set temperature and the second set temperature every 10 minutes, the storage unit 13 stores the set temperature with respect to time as a one-cycle temperature pattern in 0 to 10 minutes. ing. The temperature control circuit 92 controls the temperature of the heating unit 3 so as to periodically repeat the one-cycle temperature pattern stored in the storage unit 13.

  This fragrance generating apparatus uses an operation switch as a touch sensor. That is, by not using a physical push button or the like, it is possible to avoid a situation where the water is flooded from the hole of the button and maintain a waterproof structure. A circuit for realizing the touch sensor is provided on a circuit board.

  The temperature control circuit 92 supplies power from the secondary battery 1 to the heating unit 3 by the control unit 6 so that the temperature pattern stored in the storage unit 13 is the temperature of the oil tray unit 4 that is the heating unit 3. To control. The control unit 6 includes a switching element 11 connected between the secondary battery 1 and the planar PTC heater 3A, and a control circuit 12 including a microcomputer for controlling the switching element 11 to ON / OFF. . Since the fragrance generating apparatus 100 using the heating means 3 as a PTC heater connects the PTC heater, the switching element 11 and the secondary battery 1 in series, the PTC heater can be used in the protection circuit of the secondary battery 1. Even if the switching element 11 is internally short-circuited or welded and held in the ON state, the PTC heater has a suddenly large electrical resistance at the set temperature, and the current is substantially cut off to protect the secondary battery 1. It is.

  The control circuit 12 switches the switching element 11 to ON / OFF to control the temperature of the oil tray unit 4 that is the heating unit 3 to the set temperature of the temperature pattern stored in the storage unit 13. In order to detect the temperature of the heating means 3, the temperature control circuit 92 includes a temperature sensor 10. The temperature sensor 10 shown in the figure detects the temperature of the oil tray section 4 that is the heating means 3. However, the temperature sensor 10 can also detect the temperature of the heating means 3. The control circuit 12 compares the detected temperature detected by the temperature sensor 10 with the set temperature of the temperature pattern stored in the storage unit 13 and switches the switching element 11 to ON when the detected temperature is lower than the set temperature. When the temperature is detected and the detected temperature is higher than the set temperature, the switching element 11 is switched to OFF so that the temperature is not heated, and the set temperature is controlled.

  The control unit 6 of the temperature control circuit 92 adjusts the temperature gradient at which the temperature decreases by controlling the duty for switching the switching element 11 ON / OFF in a state where the temperature is decreased from the first set temperature to the second set temperature. can do. When the duty for switching the switching element 11 to ON / OFF, that is, the ratio of the ON time to the OFF time, is reduced, the power consumption supplied from the secondary battery 1 to the heating means 3 is reduced, and the heating value of the heating means 3 is reduced. To do. Therefore, the ON time of the switching element 11 can be shortened, that is, the duty can be reduced, and the temperature of the oil tray portion 4 that is the heating means 3 can be gradually lowered. The rate at which the temperature of the oil tray portion 4 decreases can be increased by shortening the ON time of the switching element 11. Therefore, the fragrance generating apparatus of the present invention does not necessarily store the temperature pattern in the storage unit 13 and controls the amount of heat generated by the heating means 3 to decrease the temperature from the first set temperature to the second set temperature. Can be controlled. The fragrance generating device 100 causes the storage unit 13 to store a duty for switching the switching element 11 ON / OFF at a timing when the temperature is decreased from the first set temperature to the second set temperature. Furthermore, the temperature gradient at which the temperature of the oil tray section 4 decreases from the first set temperature to the second set temperature also varies depending on the outside air temperature. When the outside air temperature is low, the temperature gradient at which the temperature decreases increases. This problem can be solved by storing the duty for the outside air temperature in the storage unit 13. That is, by changing the duty with respect to the temperature, for example, as the outside air temperature decreases, the duty for switching the switching element 11 to ON / OFF is increased, thereby reducing the first set temperature to the second set temperature. Variation in temperature gradient can be reduced.

  The temperature control circuit 92 in FIG. 14 connects the USB terminal 14 to the control circuit 12. The USB terminal 14 is provided in the case 2 as shown by a chain line in FIG. The USB terminal 14 is connected to a computer. The temperature control circuit 92 is connected to the computer via the USB terminal 14 and can change the set temperature stored in the storage unit 13 by a control signal input from the computer. The fragrance generating apparatus 100 is connected to a computer and can be adjusted to a set temperature optimum for the user.

Furthermore, the fragrance generating device 100 in FIG. 14 has a plurality of LEDs 15 connected to a temperature control circuit 92. As shown in FIG. 4, the LED 15 is fixed to the circuit board 7 built in the case 2, and the blinking state is controlled by the temperature control circuit 92. In the illustrated fragrance generating apparatus 100, the first case 2A disposed above the LED 15 is made of light-transmitting plastic. This case 2 can transmit the light emitted from the LED 15 and display it outside without providing an opening window for exposing the LED 15. However, the case can be displayed on the outside by providing an opening window so that the LED is exposed from the case. The temperature control circuit 92 stores a lighting pattern for lighting the LED 15 in the storage unit 13 of the control circuit 12. The lighting pattern of the LED 15 stored in the storage unit 13 of the control circuit 12 is changed by a computer connected via the USB terminal 14. The fragrance generating apparatus 100 can be changed to a lighting pattern that the user prefers by connecting a computer and controlling the lighting state of the LED 15.
(Luminescent body 15)

  One or more LEDs 15 can be provided in the case 2. Further, the lighting pattern of the LED 15 can be changed according to the remaining capacity of the secondary battery 1. In other words, the LED 15 is turned on at a predetermined timing, and the lighting pattern at this time is set in advance to a specific remaining capacity display lighting pattern determined according to the remaining capacity of the secondary battery 1. From the lighting pattern, the remaining capacity of the secondary battery 1 of the fragrance generator 100 can be grasped. The predetermined timing can be set, for example, when the power switch 19A of the fragrance generating apparatus 100 is turned on, when it is turned off, or when it is pressed for a predetermined number of seconds or longer. In particular, by executing the remaining capacity display lighting pattern when the power is turned off, the user can be urged to charge the battery when the remaining capacity is low. Therefore, charging is performed so that the fragrance generating device 100 can be used quickly at the next use. An urging effect is obtained, which is preferable. Further, the power switch 19A can also be used as an execution switch for the remaining capacity display lighting pattern, and an increase in the number of parts can be avoided.

  Further, the remaining capacity display lighting pattern can be constituted by the number of times the LED 15 blinks or the time, the lighting color of the LED 15, or a combination thereof. As an example of the remaining capacity display lighting pattern, after the power switch 19A is switched from ON to OFF, the green LED 15 is lit or blinked for 3 seconds to be displayed. For example, when the remaining capacity of the secondary battery 1 is 70% or more, it is lit in green for 3 seconds as charging is not necessary, and when it is 40% to 70%, it is slowly flashed in green as usable (for example, 3 seconds at 1 second intervals). Blinking), if it is 40% or less, it needs to be charged and blinks quickly in green (for example, blinking for 3 seconds at intervals of 0.5 seconds). Moreover, the light emission color of LED15 is not limited to only one color, but can be a plurality of light emission colors. For example, when the remaining capacity of the secondary battery 1 is 70% or more, it is lit green for 5 seconds, when it is 40% to 70%, it blinks yellow for 5 seconds, when it is 40% or less, it blinks red for 8 seconds, etc. it can. In particular, when the remaining capacity is small, it is preferable to combine red, which has a high effect of calling attention, and blinking at short time intervals. The control of the remaining capacity display lighting pattern of the LED 15 is performed by the control circuit 12 that detects the remaining capacity of the secondary battery 1. The remaining capacity can be obtained by measuring the voltage of the secondary battery 1. In addition to setting the remaining capacity display lighting pattern in advance, the user may change the computer from a computer connected via the USB terminal 14 as described above. The remaining capacity display lighting pattern is recorded in the storage unit 13. In addition, when changing the lighting color of LED, it cannot be overemphasized that one or more LED which can be changed into a different luminescent color, or several LED from which a lighting color differs is used.

4 has a shielding plate disposed along the flat surface 1a of the secondary battery 1, and further, a planar PTC heater 3A is disposed in parallel on the lower surface of the shielding plate. That is, the flat surface 1a of the secondary battery 1, the shielding plate, and the planar PTC heater 3A are stacked in a parallel posture. The fragrance generating device 100 having this structure can conduct the heat of the planar PTC heater 3A to the secondary battery 1 through the shielding plate. Since the heat of the planar PTC heater 3A is not directly conducted to the secondary battery 1, the secondary battery 1 is not heated by the planar PTC heater 3A. However, a part of the heat generated by the planar PTC heater 3A is indirectly conducted to the secondary battery 1 through the shielding plate. The aroma generating device 100 can preheat the secondary battery 1 by energizing the planar PTC heater 3A in an extremely low temperature environment. As shown in FIG. 14, the fragrance generating device 100 has a temperature sensor 18 that detects the temperature of the secondary battery 1 connected to the control circuit 12. When the temperature sensor 18 detects that the battery temperature is lower than the set temperature, the control circuit 12 switches the switching element 11 to ON and preheats the secondary battery 1 with the planar PTC heater 3A. At this time, the control circuit 12 controls the duty of switching the switching element 11 ON / OFF to control the temperature of the planar PTC heater 3A, and warms the secondary battery 1 at the temperature of the planar PTC heater 3A. Specify the temperature. The secondary battery 1 does not need to be heated to a high temperature unlike the oil tray portion 4. Therefore, the switching element 11 that preheats the secondary battery 1 controls the duty to reduce the consumption of the secondary battery 1 so that the ON time is shortened.
(Contactless charging)

Furthermore, as shown in FIG. 15, the fragrance generating apparatus 100 has a non-contact charging circuit 32 built in the charging circuit 35, and the built-in secondary battery 1 is charged by the non-contact charging circuit 32. As shown in FIG. 15, the charging circuit 35 including the non-contact charging circuit 32 includes a power receiving coil 33 and a rectifying circuit 34 that rectifies the alternating current induced in the power receiving coil 33 and converts it into direct current. Yes. The output of the rectifier circuit 34 is input to the charge control unit 36 to charge the secondary battery 1. As shown in FIG. 16, the fragrance generating device 100 including the contactless charging circuit 32 is placed on the charging stand 40 including the power transmission coil 41 to charge the secondary battery 1. The charging stand 40 includes a power transmission coil 41 for transmitting high-frequency power to the contactless charging circuit 32 by electromagnetic induction, and a power supply circuit 42 for supplying high-frequency power to the power transmission coil 41. In this way, the fragrance generating device 100 that charges the secondary battery 1 with the contactless charging circuit 32 can be conveniently charged without any connector contact failure.
(Charging circuit 25)

  Further, the secondary battery 1 can be charged by directly connecting the fragrance generating device 100 to an AC adapter or a commercial power source. The fragrance generating device 100 of FIG. 14 has a charging circuit 25 for the secondary battery 1 built in the case 2. The charging circuit 25 is mounted on the circuit board 7 built in the case 2. The charging circuit 25 includes a charge control unit 26 that charges a lithium ion secondary battery or a lithium polymer battery as the secondary battery 1. The charging control unit 26 performs constant current / constant voltage charging of the secondary battery 1 to detect full charging, and stops charging. Further, the charging circuit 25 shown in the figure has a protective FET 27 connected in series with the secondary battery 1, and the protective FET 27 is controlled by the protective circuit 28. The protection circuit 28 detects overcharge or overdischarge of the secondary battery 1 and controls the protection FET 27 to be turned on / off. When the charged secondary battery 1 is fully charged and overcharged, the protection circuit 28 switches the protection FET 27 to OFF and stops charging. Further, when the discharged secondary battery 1 is overdischarged, the protection circuit 28 switches the protection FET 27 to OFF to stop the discharge of the secondary battery 1.

  14 is connected to an AC adapter 29, and direct current for charging the secondary battery 1 is input from the AC adapter 29. The fragrance generating device 100 is provided with a DC jack 30 for connecting the AC adapter 29, and the DC jack 30 is connected to the charging circuit 25. Since the fragrance generating device 100 does not incorporate a circuit for converting the commercial power source into the charging voltage of the secondary battery 1, the charging circuit 25 can be made small.

Furthermore, the fragrance generating apparatus 100 that supplies DC power to the charging circuit 25 to charge the secondary battery 1 connects the charging circuit 25 to the USB terminal 14 as shown by the chain line in FIG. The secondary battery 1 can be charged by connecting to a terminal having a power feeding function such as a PC. These circuits are mounted on the circuit board 7.
(Charging stand 40)

  The charging stand 40 receives power from the outside and charges the secondary battery 1. As shown in the exploded perspective view of FIG. 13, the charging base 40 includes a mounting base 43, a power transmission coil 41, a power transmission shield 44, a charging base board 45, a speaker 46, and a charging base case 47. The As shown in the perspective view of FIG. 1 and the exploded perspective view of FIG. 13, the charging stand 40 has an upper surface as a mounting table 43 for mounting the aroma generating device 100, and the aroma generating device mounted here. A power receiving coil 33 incorporated in 100 and a power transmitting coil 41 that can be electromagnetically coupled are provided inside the charging stand case. With this configuration, the fragrance generating device 100 arranged on the mounting table 43 can be charged in a contactless manner by electromagnetically coupling the power reception coil 33 incorporated therein and the power transmission coil 41 of the charging table 40. Thereby, the advantage which can charge the fragrance generating apparatus 100 without a contact using the charging stand 40 is acquired.

  Furthermore, the charging stand 40 can utilize a music reproduction function effectively by incorporating a speaker. As a result, music and the like can be played along with the fragrance, and the healing effect can be enhanced by playing music with a high relaxing effect.

  Moreover, although not shown in figure, the following functions can also be added to the fragrance generating apparatus of a present Example. For example, the heating means of the fragrance generator is used as a squirrel furnace that warms a part or the whole of the case. Further, the outer shape of the case of the fragrance generating device can be a plate-shaped heart shape. It is heart-shaped and has a warm temperature as an aroma generating device, so that the user can feel emotionally warm. In addition, this heart-shaped fragrance generator has a vibration function so that it can be vibrated when needed by operating the button. When you do, you can give the recipient the impression that the heart of the person who is delivering is throbbing. Further, the outer shape of the case, the appearance of the pattern, etc., can be a plate-shaped smoldering mold. By giving the above-mentioned vibration function to such a scallop-type fragrance generating device, it is possible to give the user a pleasant impression by giving the impression that the candy is moving dynamically. Similarly, the appearance of the case, such as the outer shape and pattern, can be a plate-like animal, a character such as a manga, and the user can have a pleasant impression. Furthermore, a digital music playback function using a format such as MP3, MP4, AAC, or WMA can be added to the fragrance generating apparatus.

  As described above, according to the present invention, it is possible to realize a wireless, portable aroma generating device that does not use an AC adapter or the like. In particular, with a secondary battery, it can be used repeatedly by charging, and even if the secondary battery is exhausted, it can be reused by replacing it with a new one. Can with equipment. In addition, by making the secondary battery removable, you can replace the old secondary battery to extend the service life of the fragrance generator, or remove the secondary battery from the fragrance generator that can no longer be used. The secondary battery can be reused, such as by reusing the secondary battery.
