It may be.

<Intermediate layer>
Moreover, the photoelectric conversion element 7 may further include an intermediate layer from the viewpoint of improving the photoelectric conversion efficiency. Examples of the intermediate layer include a charge transport layer (a hole transport layer or an electron transport layer), a charge block layer (a hole block layer or an electron block layer), and a buffer layer. As the intermediate layer, a layer having flexibility and light transmittance is used. For example, examples of the material for the intermediate layer include alkali metals such as lithium fluoride, halides of alkaline earth metals, and oxides. In addition, examples of the material for the intermediate layer include fine particles of inorganic semiconductor such as titanium oxide, PEDOT (poly-3,4-ethylenedioxythiophene), and the like.

<Operation of Drug Diffusion Device 1>
As shown in FIGS. 2 and 6, when the photoelectric conversion element 7 receives light, the motor body 36 is driven by the electromotive force of the photoelectric conversion element 7. When the motor main body 36 is driven, the impeller 30 starts to rotate together with the output shaft 37. Thereafter, the impeller 30 continues to rotate in a certain rotational direction. When the impeller 30 rotates, outside air is sucked into the cylinder portion 111 from the gas inflow hole 5h in the direction of the arrow V1. The outside air bypasses the inside in the direction of the arrow V2, then changes direction to the direction of the arrow V3, and is discharged to the outside from the gas outflow hole 6h.

Then, the fragrance vaporized from the fragrance liquid 10 rises in the direction of the arrow V4 so as to be drawn by the outside air flowing in the order of arrows V1, V2, and V3, and from the gas outflow hole 6h, a mixed gas of the outside air and the fragrance. Is released. Thereafter, the fragrance evaporated from the fragrance liquid 10 gradually diffuses into the space (for example, the room) around the drug diffusion device 1.

As described above, the drug diffusing device 1 according to the present embodiment includes the container 2 having the passage portion 28 through which the fragrance vaporized by the fragrance liquid 10 can pass, the blower 3 capable of diffusing the fragrance by blowing, and the passage portion. 28, the cover 4 attached to the container 2 in a state of covering the blower 3, the photoelectric conversion element 7 that can convert light as driving power of the blower 3, and the direction of the photoelectric conversion element 7 Includes a support member 15 that can be changed between a first direction in which light can be received and a second direction in which the photoelectric conversion element 7 cannot receive light.

According to this embodiment, the direction of the photoelectric conversion element 7 is changed between a first direction in which the photoelectric conversion element 7 can receive light and a second direction in which the photoelectric conversion element 7 cannot receive light. By providing the possible support member 15, the following effects are produced. When the fragrance liquid 10 is diffused, the fan 3 can be driven by causing the photoelectric conversion element 7 to receive light with the direction of the photoelectric conversion element 7 as the first direction. On the other hand, when the diffusion of the fragrance liquid 10 is stopped, the blower 3 can be stopped by setting the direction of the photoelectric conversion element 7 as the second direction so that the photoelectric conversion element 7 does not receive light. Therefore, it is not necessary to change the arrangement of the drug diffusion device 1 (that is, the arrangement of the drug diffusion device 1 main body).
Therefore, the diffusion of the fragrance liquid 10 can be easily controlled.

Further, since the support member 15 has flexibility and can support the photoelectric conversion element 7 in a state where at least the direction of the photoelectric conversion element 7 is in the first direction, the following effects can be obtained. Since the support member 15 has flexibility, the direction of the photoelectric conversion element 7 can be changed by a simple method of bending the support member 15. For this reason, diffusion of the fragrance liquid 10 can be controlled even more easily. In addition, since the photoelectric conversion element 7 can be supported at least in the state where the direction of the photoelectric conversion element 7 is the first direction, the state where the blower 3 is driven can be stably maintained. For this reason, diffusion of the fragrance liquid 10 can be performed stably.

Further, since the support member 15 includes a tubular member 17 having a tubular shape extending between the photoelectric conversion element 7 and the blower 3 and the wiring 9 is disposed inside the tubular member 17, the following effects are produced. Compared with the case where the wiring 9 is arranged outside the tubular member 17, the wiring 9 does not get in the way when the support member 15 is bent, and the direction of the photoelectric conversion element 7 can be easily changed. . For this reason, diffusion of the fragrance liquid 10 can be controlled even more easily. Moreover, since the wiring 9 can be made inconspicuous, the design can be improved.

Moreover, since the flexible organic photoelectric conversion element is easy to cut and has a high degree of freedom in shape, it is possible to effectively improve the design as compared with the case of a silicon-based solar cell. Moreover, compared with the case of a silicon-type solar cell, while improving the power generation performance with respect to room light, cost reduction can be achieved.
In addition, since the organic photoelectric conversion element can increase the voltage of one cell as compared with the silicon-based solar battery, the torque of the motor 35 can be increased without excessively increasing the series number of the photoelectric conversion elements 7. It can be ensured, and the aroma can be stably diffused.

Further, the photoelectric conversion element 7 has a light transmission property for at least visible light. In addition, the photoelectric conversion element 7 includes an active layer 73 having an average transmittance of 10% or more for light in a wavelength range of 400 nm or more and 700 nm or less. Thereby, since the part which has arrange | positioned the photoelectric conversion element 7 can be visually recognized from the outside, design property can be improved effectively.

For example, when the photoelectric conversion element 7 has optical transparency, the plurality of photoelectric conversion elements 7 may be arranged so as to overlap each other when viewed from the light traveling direction. That is, the plurality of photoelectric conversion elements 7 may include a first photoelectric conversion element and a second photoelectric conversion element through which light that has passed through the first photoelectric conversion element can pass. In addition, each photoelectric conversion element may be supported by a support main body having light transparency with respect to at least visible light. In this case, a light shielding film is not disposed on the second surface of the support portion main body.
According to this structure, since the light which passed the 1st photoelectric conversion element reaches the 2nd photoelectric conversion element, it can be made to generate electric power in a 1st photoelectric conversion element and a 2nd photoelectric conversion element. Therefore, compared with the case where a photoelectric conversion element does not have light transmittance, electric power generation amount can be raised effectively.

In the present embodiment, the first electrode 71 and the second electrode 72, which are a pair of electrodes, have been described as having light transmittance, but the present invention is not limited thereto. For example, at least one of the first electrode 71 and the second electrode 72 that are a pair of electrodes may have light transmittance. Thereby, light can be transmitted through the active layer 73 of the photoelectric conversion element 7. For example, when the first electrode 71 has light transmission, the second electrode 72 may not have light transmission. However, in this case, a configuration in which the plurality of photoelectric conversion elements 7 are arranged so as to overlap when viewed from the traveling direction of light is excluded.

For example, examples of the material of the electrode that does not have optical transparency (hereinafter referred to as “opaque electrode”) include metals and conductive organic materials. Specifically, materials that do not have optical transparency include lithium, sodium, potassium, rubidium, cesium, magnesium, calcium, strontium, barium, aluminum, scandium, vanadium, zinc, yttrium, indium, cerium, samarium, europium, Metals such as terbium and ytterbium; two or more of these alloys; 1 or more selected from the group consisting of one or more of the above metals and gold, silver, platinum, copper, manganese, titanium, cobalt, nickel, tungsten and tin And alloys with more than one metal; and graphite, graphite intercalation compounds, polyaniline, polyaniline derivatives, polythiophene, polythiophene derivatives, and the like. For example, examples of the alloy include a magnesium-silver alloy, a magnesium-indium alloy, a magnesium-aluminum alloy, an indium-silver alloy, a lithium-aluminum alloy, a lithium-magnesium alloy, a lithium-indium alloy, and a calcium-aluminum alloy.

The thickness of the opaque electrode can be set from the viewpoint of ensuring flexibility and suppressing the electric resistance. For example, the thickness of the opaque electrode can be preferably in the range of 50 to 5000 nm, more preferably in the range of 100 to 3000 nm.

Further, when at least one of the first electrode 71 and the second electrode 72 as a pair of electrodes is an opaque electrode, the substrate 70 on the opaque electrode side may not have light transmittance. For example, aluminum, copper, etc. are mentioned as a material of the board | substrate which does not have a light transmittance (henceforth "an opaque board | substrate"). However, in this case, an opaque electrode is disposed on the opaque substrate via an insulating film. The thickness of the opaque substrate can be set in consideration of the viewpoint of ensuring flexibility and the stability when the photoelectric conversion element 7 is manufactured. For example, the thickness of the opaque substrate can be preferably in the range of 10 to 5000 μm, more preferably in the range of 50 to 3000 μm.

In the present embodiment, the example in which the gas inflow portion 5 and the gas outflow portion 6 are provided in the cylindrical portion 111 has been described. However, the present invention is not limited thereto. For example, the gas inflow part 5 and the gas outflow part 6 may be provided in parts other than the cylinder part 111. Further, at least one of the gas inflow portion 5 and the gas outflow portion 6 may be provided separately from the container 2 and the cover 4.

In the present embodiment, the blower 3 is described with an example including the impeller 30 and the motor 35 that rotationally drives the impeller 30, but is not limited thereto. For example, it may replace with the motor 35 of this embodiment, and may be provided with the coil and the magnet. Further, a parallel capacitor may be provided between the photoelectric conversion element 7 and the blower 3. That is, various blowers can be adopted as long as the fragrance can be diffused by blowing.

In the present embodiment, components that are the same as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

In 1st embodiment, as shown in FIG. 1, the chemical | medical agent diffusion apparatus 1 gave the example provided with the supporting member 15 which can support the photoelectric conversion element 7 while having flexibility as a direction change part. . In contrast, in the present embodiment, as shown in FIGS. 10 to 12, the drug diffusing device 201 has a hinge 210 that supports the photoelectric conversion element 7 so as to be rotatable around the axis C1 as a direction changing unit. Prepare. Moreover, in 1st embodiment, as shown in FIG. 1, the container 2 and the cover 4 gave the example which has a column shape. On the other hand, in this embodiment, as shown in FIGS. 10 to 12, the container 202 and the cover 204 have a rectangular parallelepiped shape.

<Hinge>
Specifically, the hinge 210 supports the photoelectric conversion element 7 so as to be rotatable around the axis C1 with at least the direction of the photoelectric conversion element 7 being the first direction. The hinge 210 includes a first support member 211 that supports one of the two photoelectric conversion elements 7 and a second support member 215 that supports the other of the two photoelectric conversion elements 7.

The 1st support member 211 is provided with the 1st support plate 212 which supports the photoelectric conversion element 7, and the 1st cylindrical member 213 (cylindrical member) which has the cylindrical shape which forms the axis line C1.

The first support plate 212 includes a first surface 212a that is a support surface that supports the photoelectric conversion element 7, and a second surface 212b that is located on the opposite side of the first surface 212a. When viewed from the thickness direction of the first support plate 212, the first support plate 212 has a rectangular shape that is substantially the same size as the top plate portion 240 of the cover 204. At least the second surface 212b of the first support plate 212 has a light shielding property. For example, a light shielding film is formed on the second surface 212b so as to cover the entire second surface 212b.

The first tubular member 213 extends along one side of the first support plate 212. The first tubular member 213 is fixed to the central portion of one side of the first support plate 212.

The second support member 215 includes a second support plate 216 that supports the photoelectric conversion element 7 and a second cylindrical member 217 (cylindrical member) having a cylindrical shape that forms the axis C1.

The second support plate 216 has a first surface 216a that is a support surface that supports the photoelectric conversion element 7, and a second surface 216b that is located on the opposite side of the first surface 216a. The second support plate 216 has substantially the same size as the first support plate 212. When viewed from the thickness direction of the second support plate 216, the second support plate 216 has a rectangular shape substantially the same size as the side portion 241 of the cover 204 and the side wall portion 220 of the container 2. The second support plate 216 is fixed to the side part 241 of the cover 204 and the side wall part 220 of the container 2.

The second cylindrical member 217 extends along one side adjacent to the first support plate 212 among the four sides of the second support plate 216. The pair of second cylindrical members 217 are provided so as to sandwich the first cylindrical member 213 from both sides of the first cylindrical member 213. The pair of second cylindrical members 217 are fixed to both ends of the one side of the second support plate 216.

The pair of second cylindrical members 217 supports the first cylindrical member 213 so as to be rotatable around the axis C1. In other words, the first cylindrical member 213 is connected to the pair of second cylindrical members 217 so as to be rotatable about the axis C1. The wiring 9 is disposed inside the first cylindrical member 213 and the pair of second cylindrical members 217. The wiring 9 extends along the first cylindrical member 213 and the pair of second cylindrical members 217, and electrically connects the two photoelectric conversion elements 7 and the blower 3 (see FIG. 6). The first tubular member 213 and the second tubular member 217 correspond to “tubular members”.

The hinge 210 according to the present embodiment rotates the first support plate 212 around the axis C1 so that the orientation of the first support plate 212 is changed to the “open state” shown in FIG. 10 and “ It can be changed between “closed state” and “closed state”. For example, in order to change the orientation of the first support plate 212 from the “open state” to the “closed state”, the first surface 212a of the first support plate 212 and the second surface in the direction of the arrow K1 shown in FIG. The first support plate 212 is rotated around the axis C1 so that the first surface 216a of the two support plates 216 is close (so that the two photoelectric conversion elements 7 are close).

In this embodiment, in the “open state”, the first surface 212a of the first support plate 212 and the first surface 216a of the second support plate 216 are separated from each other (the light receiving surfaces of the two photoelectric conversion elements 7 are separated from each other). ) Light can be incident on the two photoelectric conversion elements 7 (the photoelectric conversion element 7 on the first surface 212a of the first support plate 212 and the photoelectric conversion element 7 on the first surface 216a of the second support plate 216). It means a certain state. That is, the “direction of the photoelectric conversion element 7 in the open state” corresponds to the “first direction” in which the photoelectric conversion element 7 can receive light.
On the other hand, in the “closed state”, the first surface 212a of the first support plate 212 and the first surface 216a of the second support plate 216 abut (the light receiving surfaces of the two photoelectric conversion elements 7 abut). A state in which light cannot enter the two photoelectric conversion elements 7 (the photoelectric conversion element 7 on the first surface 212a of the first support plate 212 and the photoelectric conversion element 7 on the first surface 216a of the second support plate 216). Means. That is, the “direction of the photoelectric conversion element 7 in the closed state” corresponds to a “second direction” in which the photoelectric conversion element 7 cannot receive light.

The first cylindrical member 213 and the pair of second cylindrical members 217 are in the “open state”, “closed state”, and “state between the open state and the closed state” in the respective states. The conversion element 7 and the first support plate 212 are connected so as to be held at a fixed position.

For example, when the fragrance liquid 10 is diffused, the direction of the first support plate 212 is set to the “open state” shown in FIG. 10 so that the photoelectric conversion element 7 receives light and drives the blower 3.
On the other hand, when the diffusion of the fragrance liquid 10 is stopped, the blower 3 is configured so that the photoelectric conversion element 7 does not receive light by setting the direction of the first support plate 212 to the “closed state” shown in FIG. Stop.

According to the present embodiment, the hinge 210 supports the photoelectric conversion element 7 so as to be rotatable around the axis C1 with at least the direction of the photoelectric conversion element 7 set to the first direction. The direction of the photoelectric conversion element 7 can be changed by a simple method using the rotation of the rotation. For this reason, diffusion of the fragrance liquid 10 can be controlled even more easily. Moreover, since the state which the air blower 3 drives can be maintained stably, the spreading | diffusion of the fragrance | flavor liquid 10 can be performed stably.

Further, the hinge 210 includes a first cylindrical member 213 and a pair of second cylindrical members 217 that form the axis C <b> 1, and the wiring 9 is disposed inside the first cylindrical member 213 and the pair of second cylindrical members 217. As a result, the following effects are obtained. Compared with the case where the wiring 9 is arranged outside the first cylindrical member 213 and the pair of second cylindrical members 217, the wiring 9 is obstructed when the photoelectric conversion element 7 is rotated around the axis C1. Therefore, the orientation of the photoelectric conversion element 7 can be easily changed. For this reason, diffusion of the fragrance liquid 10 can be controlled even more easily. Moreover, since the wiring 9 can be made inconspicuous, the design can be improved.
