DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are denoted by the same reference numerals, and redundant description will be omitted.

[0012] The explanation will be given in the following order. 1. Overview of the scent providing device 2. Example of the composition of the fragrance cartridge (fragrance holding structure) 3. Example of the scent providing device configuration 4. Manufacturing method of fragrance cartridge (fragrance holding structure)

[0013] In the following description, the direction in which the aroma is blown out may be referred to as the front side or the tip side, and the opposite direction may be referred to as the rear side or the rear end side.

[0014] <1. Overview of the scent providing device> First, a brief overview of the aroma provision device according to an embodiment of the present disclosure will be given. Fig. 1 is a perspective view showing the exterior of the aroma provision device 1 according to the present embodiment, and Fig. 2 is an axial cross-sectional view of the aroma provision device 1.

[0015] The aroma providing device 1 according to this embodiment includes a fragrance cartridge 200 and a device main body 700. The device main body 700 has a housing 710, in which a battery 810, an air pump 840, and a circuit board 820 that controls the power supply from the battery 810 to the air pump 840 are provided. The fragrance cartridge 200 is detachably attached to the front side of the device main body 700. In this embodiment, the fragrance cartridge 200 corresponds to the fragrance holding structure.

[0016] The aroma providing device 1 flows air into a desired retention space 231 selected from a plurality of retention spaces 231 (only one retention space 231c is shown in FIG. 2) provided in the aroma cartridge 200, and vaporizes and releases the aroma held in an aroma holder (not shown) arranged in each retention space 231. For example, the aroma providing device 1 vaporizes a liquid aroma or a moist aroma (hereinafter collectively referred to as "liquid aroma") and releases it from the retention space 231 together with the air by passing air supplied from the air pump 840 through the retention space 231 of the aroma cartridge 200.

[0017] The scent provision device 1 according to this embodiment is used, for example, as a device that releases a scent in a limited range of space. For example, a user releases a scent from the scent provision device 1 once or multiple times near their face to relax their mood. In this case, the scent provision device 1 releases the scent with high linearity and is less likely to diffuse over a wide area, making it difficult for people in the vicinity to detect the scent. The scent provision device 1 may be a portable type that can be carried by the user, or a stationary type.

[0018] <2. Fragrance cartridge (fragrance holding structure)> Next, the fragrance cartridge 200 as the fragrance holding structure according to this embodiment will be described in detail.

[0019] 3 to 7 are diagrams for explaining a configuration example of the fragrance cartridge 200. FIG. 3 is a perspective view showing the exterior of the fragrance cartridge 200. FIG. 4 is a front view of the fragrance cartridge 200 as viewed in the axial direction from the front side, and FIG. 5 is a rear view of the fragrance cartridge 200 as viewed in the axial direction from the rear side. FIG. 6 is an axial cross-sectional view of the fragrance cartridge 200, and is a view seen from the arrow II cross-section shown in FIGS. 4 and 5. FIG. 7 is an exploded perspective view of the fragrance cartridge 200.

[0020] The flavor cartridge 200 has a cylindrical appearance overall. The flavor cartridge 200 has a plurality of (five in this embodiment) holding spaces 231a to 231e (hereinafter, collectively referred to as holding spaces 231 unless a distinction is particularly required) that pass air supplied from an air pump 840, which is an example of an air source. A flavor holder 251 that holds a liquid flavor is disposed in the holding space 231. The flavor may be, for example, essential oil, or essential oil diluted with ethanol. There may be one holding space 231, or there may be multiple holding spaces 231.

[0021] The fragrance cartridge 200 according to this embodiment includes a case 210, a case cover 150, and a fragrance holder 251. The case 210 includes a first case body 211 and a second case body 100 fixed to the front side of the first case body 211. The case cover 150 is attached to the front surface of the case 210 so as to be freely rotatable about its axis. The fragrance holder 251 holds a liquid fragrance, and is disposed in each of a plurality of holding spaces 231 provided in the case 210.

[0022] The flavor cartridge 200 has first openings 221a to 221e (hereinafter, collectively referred to as first openings 221 unless otherwise specified) in the rear end surface, the number of which is the same as the number of the holding spaces 231. The first openings 221 open the respective holding spaces 231 to the outside. In this embodiment, the five first openings 221a to 221e, together with one pseudo hole 223, are arranged at equal intervals of 60 degrees around the axis. The flavor cartridge 200 also has one second opening 151 in the front end surface. The second opening 151 is provided in the case cover 150, and the second opening 151 can selectively communicate with any one of the multiple holding spaces 231 by rotating the case cover 150 and the case 210 relative to each other.

[0023] This allows the holding space 231 through which air passes to be switched by axially rotating the case 210 of the fragrance cartridge 200 at a certain rotation angle. The fragrances held in each holding space 231 may all be the same, or some or all of them may be different. When the same fragrance is held in each holding space 231, the user can enjoy his / her favorite fragrance for a long period of time. When different fragrances are held in each holding space 231, the fragrance to be released can be switched by switching the holding space 231 through which air can be supplied. Therefore, for example, the fragrance can be switched depending on mood.

[0024] In the fragrance cartridge 200 according to this embodiment, five retention spaces 231 are arranged at equal intervals of 60 degrees, while one space is a pseudo space 232. When the fragrance providing device 1 is not in use, the pseudo space 232 is aligned with the second opening 151 of the case cover 150 to prevent the fragrance from escaping from each retention space 231 of the fragrance cartridge 200. The number of retention spaces 231 is not limited to five. Furthermore, the retention spaces 231 do not have to be arranged at equal intervals.

[0025] The flavor cartridge 200 has a protrusion 212 on its outer circumferential surface, which serves as a positioning element when attaching the flavor cartridge 200. The protrusion 212 is formed so that the protrusion 113 of the second case body 100 and the protrusion 213 of the first case body 211 are connected to each other, and has a predetermined length along the axial direction.

[0026] The flavor cartridge 200 has recesses 217 on the outer peripheral surface at the rear end side, the number of which is equal to the total number of the holding spaces 231 and the pseudo spaces 232. In this embodiment, the recesses 217 are provided at equal intervals of 60 degrees in the circumferential direction. The recesses 217 are provided at positions corresponding to the positions of the first opening 221 and the pseudo holes 223 provided on the rear end surface. The recesses 217 have a function of fixing the case 210 at a predetermined rotational position and giving the user a feeling of rotational operation by engaging with an engaging element provided on the device main body 700. Note that the recesses 217 may be provided in the circumferential direction at the same phase intervals as the first opening 221 and the pseudo holes 223, and may not be provided at equal intervals, and may be shifted from the positions of the first opening 221 and the pseudo holes 223.

[0027] A label 255 is affixed to the outer peripheral surface of the first case body 211 located in the axial center of the aromatic cartridge 200, excluding the protrusion 213. The label 255 displays, for example, information about the scent of the aromatic support 251 arranged in each support space 231. The label 255 does not necessarily have to be provided.

[0028] Below, the fragrance cartridge 200 will be described in detail with respect to each of its components.

[0029] (First case body) 8 to 10 are diagrams for explaining the first case body 211. FIG. 8 is a front view of the first case body 211 as viewed in the axial direction from the front side. FIG. 9 is an axial cross-sectional view of the first case body 211, taken along the line II-II in FIG. 8. FIG. 10 is a circumferential cross-sectional view of the first case body 211, corresponding to the cross-sectional view taken at the position III-III shown in FIG. 9. Note that a rear view of the first case body 211 as viewed in the axial direction from the rear side corresponds to the rear view of the flavoring cartridge 200 shown in FIG. 11.

[0030] The first case body 211 has a cylindrical outer shape whose axial length is longer than its diameter. An axial hole 215 that opens to both axial ends is provided in the center of the first case body 211. A plurality of (five in this embodiment) holding spaces 231 and pseudo spaces 232 are provided around the axial hole 215 at predetermined intervals (equally spaced at 60 degrees in this embodiment) around the axis. Each of the plurality of holding spaces 231 and pseudo spaces 232 has a sector-shaped circumferential cross-sectional shape.

[0031] The plurality of holding spaces 231 and the pseudo space 232 each open to the front side of the first case body 211. The rear side of each of the plurality of holding spaces 231 is open to the outside through the first opening 221, while the rear side of the pseudo space 232 is closed. The plurality of holding spaces 231 are formed with first ribs 235a to 235e (hereinafter, collectively referred to as the first rib 235 unless otherwise required) that divide the rear end of each of the holding spaces 231 in the circumferential direction. In each of the holding spaces 231, the first opening 221 is disposed on one side of the region divided in the circumferential direction by the first rib 235. Therefore, the plurality of first openings 221 are also disposed at equal intervals of 60 degrees around the axis in accordance with the arrangement of the holding spaces 231.

[0032] A protrusion 213 having a predetermined length along the axial direction is provided on the outer circumferential surface of the first case body 211 at a position corresponding to the outer circumferential portion of the pseudo space 232. A hole 227 that communicates the outer circumferential surface of the first case body 211 with the pseudo space 232 is provided adjacent to the front side of the protrusion 213. The hole 227 has a function of fixing the first case body 211 and the second case body 100 together in cooperation with an engagement protrusion (117) of the second case body 100. The hole 227 may be a recess that does not reach the pseudo space 232. A plurality of holes 227 may be provided at different phase positions.

[0033] A recess 229 is provided in a portion of the outer circumferential surface of the front end portion of the first case body 211 that is located at the boundary between the pseudo space 232 and the holding space 231e. The recess 229 cooperates with the protrusion 119 of the second case body 100 to function as a positioning element when assembling the first case body 211 and the second case body 100. The first case body 211 may be provided with a protrusion, and the second case body 100 may be provided with a recess.

[0034] (Second case body) 11 to 14 are diagrams shown for explaining the second case body 100. Fig. 11 is a front view of the second case body 100 seen in the axial direction from the front side. Fig. 12 is a side view of the second case body 100. Fig. 13 is a rear view of the second case body 100 seen in the axial direction from the rear side. Fig. 14 is an axial cross-sectional view of the second case body 100, and is a cross-sectional view taken along the arrows IV-IV in Figs. 11 and 13.

[0035] The second case body 100 has a cylindrical outer shape with an axial length shorter than its diameter. The outer peripheral surface of the second case body 100 is knurled, and a plurality of fine grooves are formed along the circumferential direction.

[0036] The second case body 100 has an axial hole 111 at the center thereof, which opens at both ends in the axial direction. The axial hole 111 has a small diameter portion 111a at the front side and a large diameter portion 111b at the rear side. The axial hole 111 of the second case body 100 can be integrated with the axial hole 215 of the first case body 211 to form one axial hole when the second case body 100 is attached to the first case body 211. Around the axial hole 111, a plurality of (five in this embodiment) communication holes 101a to 101e (hereinafter, collectively referred to as communication holes 101 unless otherwise required to be distinguished) are provided, each of which opens at both ends in the axial direction. The plurality of communication holes 101, together with one pseudo hole 103, are provided at equal intervals (at 60 degree intervals in this embodiment) around the axial hole 111. However, the arrangement positions of the communication holes 101 do not have to be at equal intervals.

[0037] When the second case body 100 is attached to the first case body 211, the plurality of communication holes 101a-101e communicate with the holding spaces 231a-231e, respectively, and open the holding spaces 231a-231e to the outside. The first openings 221a-221e provided in the respective holding spaces 231a-231e and the respective communication holes 101a-101e of the second case body 100 are positioned in the same phase around the axis. In other words, the first openings 221 and the communication holes 101 provided in the respective holding spaces 231 are linearly connected along the axial direction.

[0038] Second ribs 121a to 121e (hereinafter, collectively referred to as second ribs 121 unless otherwise specified) are provided adjacent to the communication holes 101a to 101e on the rear end surface of the second case body 100. The second ribs 121 are erected extending rearward and are disposed in the holding space 231 of the second case body 100 in a state in which the second case body 100 is attached to the first case body 211. In addition, when the state in which the second case body 100 is attached to the first case body 211 is viewed in the axial direction, the second rib 121 of the second case body 100 and the first rib 235 of the first case body 211 are disposed so as to overlap each other. The second rib 121 of the second case body 100 and the first rib 235 of the first case body 211 divide the holding space 231 into an area (ventilation area A) facing the communication hole 101 and the first opening 221 and another area (holding area F) in which the fragrance holder 251 is arranged (see Figures 8 and 10).

[0039] The second case body 100 has a front recess 108 on the front side that accommodates the case cover 150. The second case body 100 also has a rear recess 109 on the rear side that accommodates the tip of the first case body 211. An engagement protrusion 117 that engages with the hole 227 of the first case body 211 is provided on the inner circumferential surface of the rear recess 109. In this embodiment, two engagement protrusions 117 are provided (see FIGS. 13 and 14). Also, a protrusion 119 that is inserted into the recess 219 of the first case body 211 is provided on the inner circumferential surface of the rear recess 109.

[0040] When the second case body 100 is assembled to the first case body 211, the second case body 100 and the first case body 211 are aligned using the convex portion 119 and the concave portion 219, and are fixed using the engagement protrusion 117 and the hole portion 227. At that time, when the tip portion of the first case body 211 is attached to the rear side concave portion 109 of the second case body 100, the tip surface of the first case body 211 abuts against the bottom surface of the rear side concave portion 109 of the second case body 100, and the respective holding spaces 231a to 231e are in an isolated state.

[0041] A protrusion 113 having a predetermined length along the axial direction is provided at a position on the outer circumferential surface of the second case body 100 that corresponds to the outer circumferential portion of the arrangement position of the pseudo hole 103. When the second case body 100 is attached to the first case body 211, the protrusion 113 of the second case body 100 is disposed contiguous to the protrusion 213 of the first case body 211, and the protrusion 212 is integrally formed.

[0042] (Case cover) 15 to 18 are diagrams for explaining the case cover 150. FIG. 15 is a front view of the case cover 150 as viewed in the axial direction from the front side. FIG. 16 is a side view of the case cover 150 as viewed from the side, and corresponds to the view of the case cover 150 shown in FIG. 15 as viewed from above. FIG. 17 is a rear view of the case cover 150 as viewed in the axial direction from the rear side. FIG. 18 is an axial cross-sectional view of the case cover 150, and is a view taken along the VV cross-section of FIGS. 15 and 17.

[0043] The case cover 150 has a disk portion 153 and a columnar portion 155 extending rearward from the disk portion 153. The columnar portion 155 has a hollow cylindrical shape that opens to the rear end side. The columnar portion 155 is inserted into the axial hole 111 of the second case body 100 and the axial hole 215 of the first case body 211. The disk portion 153 has a disk shape of an appropriate thickness. The disk portion 153 is housed in the front recess 108 of the second case body 100. The case cover 150 is attached to the case 210 so as to be rotatable relative to the case 210.

[0044] The case cover 150 has a second opening 151 penetrating in the axial direction in the disk portion 153. The second opening 151 can communicate with any one of the multiple communication holes 101 formed in the second case body 100 depending on the relative rotation position of the case cover 150 with respect to the case 210. In other words, the second opening 151 opens any one of the holding spaces 231 to the outside depending on the relative rotation position of the case cover 150 with respect to the case 210. An engagement protrusion 159 protruding rearward is formed on the rear end surface of the disk portion 153. The engagement protrusion 159 is a minute protrusion having a height of, for example, 0.15 to 0.3 mm, and is provided at a position where it can engage with the communication hole 101 of the second case body 100 (see FIG. 6).

[0045] The cylindrical portion 155 has a slit 155a extending in the axial direction. A protrusion (a portion indicated by reference numeral 768 in FIG. 26) provided on a fixed shaft of a base portion of the device main body 700 (described later) is inserted into the slit 155a. The cylindrical portion 155 has an engagement recess 157 formed by protruding both sides of the inner circumferential surface of the cylindrical portion 155 at the bottom of the hollow internal space. An engagement portion (a portion indicated by reference numeral 769 in FIG. 26 and FIG. 27) provided on a tip portion of a fixed shaft of the base portion of the device main body 700 is inserted into the engagement recess 157. The cylindrical portion 155 has two locking claws 156 formed rotationally symmetrically on the outer circumferential surface on the front side. With the cylindrical portion 155 of the case cover 150 inserted into the axial holes 111, 125 of the case 210, the locking claw 156 is disposed in the large diameter portion 111b of the axial hole 111 of the second case body 100 and is locked to the step portion between the small diameter portion 111a and the large diameter portion 111b (see FIG. 30). This makes it difficult for the case cover 150 to come off the case 210.

[0046] (fragrance holder) The fragrance holder 251 arranged in each of the plurality of holding spaces 231 includes a base material, and the liquid fragrance is held in the base material. For example, the fragrance holder 251 may be a holder in which the liquid fragrance is impregnated into an impregnating material as a base material. In this case, the impregnating material may be, for example, a porous or fibrous material made of polyester, nylon, felt, polyacetal, or the like. In addition, the impregnating material is preferably a material that is resistant to the liquid fragrance. The liquid fragrance may be, for example, essential oil, or essential oil diluted with ethanol. The liquid fragrance held in the fragrance holder 251 may be different for each holding space 231, or may be the same.

[0047] The flavorant holder 251 is disposed in the holding area F of the holding space 231 of the case 210 (see FIG. 6). The longitudinal dimension of the flavorant holder 251 (axial direction of the flavorant cartridge 200) may, for example, match the axial length of the holding area F. In this case, the cross-sectional shape of the flavorant holder 251 perpendicular to the longitudinal direction may approximate the circumferential cross-sectional shape of the holding area F. In other words, by having the flavorant holder 251 match or approximate the spatial shape of the holding area F, the volume of the flavorant holder 251 becomes relatively large, and therefore the amount of liquid flavor that can be held can be relatively increased.

[0048] However, the shape of the aromatic substance holder 251 is not limited to this example. For example, the aromatic substance holder 251 may be a stick-like shape such as a round or square bar, or may be a trapezoidal shape punched out of a plate-like base material. The aromatic substance holder 251 shown in Fig. 7 is made of a polygonal plate material that has the same axial length as the holding region F of the holding space 231 and whose center can be arranged adjacent to the ventilation region A side.

[0049] (Ventilation area and holding area) As described above, each holding space 231 has a ventilation area A and a holding area F. The ventilation area A is an area whose both axial ends can face the first opening 221 and the second opening 151. In this embodiment, the ventilation area A of each holding space 231 can face the second opening 151 of the case cover 150 via the communication hole 101 of the second case body 100. The holding area F is an area that is disposed adjacent to the ventilation area A and communicates with the ventilation area A, and in which the fragrance holder 251 is disposed.

[0050] The ventilation area A and the holding area F are arranged adjacent to each other and are divided by a first rib 235 formed on the first case body 211 at the rear side of the holding space 231 and a second rib 121 formed on the second case body 100 at the front side of the holding space 231. The ventilation area A and the holding area F communicate with each other via the space between the two ribs 121, 235.

[0051] Figures 19 and 20 are diagrams for explaining the ventilation area A and the holding area F of the holding space 231. Figure 19 is a diagram of the first case body 211 in which the aromatic material holding body 251 is arranged in the holding space 231, as viewed from the front side, and Figure 20 is an axial cross-sectional view typically showing the holding space 231 in which the aromatic material holding body 251 is arranged.

[0052] When the flavor cartridge 200 is viewed in the axial direction, the second rib 121 of the second case body 100 and the first rib 235 of the first case body 211 are arranged at an overlapping position. In FIG. 20, the space above the imaginary line L connecting the two ribs 121, 235 is the holding area F in which the flavor support 251 is arranged, and the space below the imaginary line L is the ventilation area A that can face the first opening 221 and the second opening 151 of the case cover 150. The ventilation area A linearly connects the first opening 221 and the second opening 151 along the axial direction. Therefore, the ventilation resistance of the air supplied from the first opening 221 into the holding space 231 and flowing through the communication hole 101 to the second opening 151 is reduced.

[0053] The retention area F is disposed adjacent to the ventilation area A in a direction intersecting the axial direction. The retention area F and the ventilation area A are in communication with each other via the space between the two ribs 121, 235. The axial center of the fragrance holder 251 disposed in the retention area F is disposed in the space between the two ribs 121, 235 and disposed close to the ventilation area A. This makes it easier for the liquid fragrance held in the fragrance holder 251 to evaporate due to the air flow passing through the ventilation area A. At this time, if the fragrance holder 251 is in the form of an impregnated material impregnated with a liquid fragrance, the liquid fragrance will permeate the part of the impregnated material located on the ventilation area A side, and the fragrance will be more likely to evaporate continuously.

[0054] The two ribs 121, 235 function as a restricting portion that restricts the movement of the aromatic material holder 251 toward the ventilation area A. In this embodiment, the recess 237 formed by the first rib 235 in the holding space 231 of the first case body 211 and accommodating one end of the aromatic material holder 251 can also be said to function as a restricting portion.

[0055] The flavor cartridge 200 according to this embodiment has a ventilation area A through which air passes on the side of the flavor support 251 arranged in the support area F, and when the air passes through the ventilation area A, the liquid flavor is vaporized and mixed with the air and released. At this time, the movement of the flavor support 251 toward the ventilation area A is restricted, so that the ventilation resistance of the air passing through the ventilation area A is not increased. In addition, the space from the first opening 221, which is the air supply port, to the second opening 151, which is the release port, is a closed space with no other openings, so that all the flavor vaporized by the ventilation can be efficiently released from the release port.

[0056] <3. Example of the configuration of the aroma providing device> So far, a configuration example of the aromatic cartridge 200 as the aromatic retention structure according to this embodiment has been described. Next, a configuration example of the aroma providing device 1 in which the aromatic cartridge 200 is attached for use will be described.

[0057] (3.1. Overall configuration example) 1 and 2, the aroma providing device 1 includes a fragrance cartridge 200 and a device main body 700. The device main body 700 includes a battery 810, a circuit board 820, and an air pump 840 provided in a housing 710, as well as a prism portion 500, a rotation operation portion 600, and a base portion 740 at the tip side of the housing 710.

[0058] The prism portion 500 is made of a transparent material and is disposed within the rotation operation portion 600. The prism portion 500 may be press-fitted into the rotation operation portion 600, or may be joined or fixed by an appropriate means. Figures 21 and 22 are explanatory diagrams showing a configuration example of the prism portion 500. Figure 21 is a front view of the prism portion 500 as viewed in the axial direction, and Figure 22 is an axial cross-sectional view of the prism portion 500.

[0059] The prism portion 500 has an axial hole 530 in which the fragrance cartridge 200 is disposed. A positioning groove 531 is formed in a part of the outer peripheral surface of the axial hole 530, which serves as a positioning element when the fragrance cartridge 200 is attached. The rear side of the prism portion 500 has a tapered shape that reduces in diameter toward the rear end. The outer surface of the tapered portion is mirror-finished to form a mirror portion 510. Therefore, the user can visually recognize characters, patterns, etc. on the outer peripheral surface of the fragrance cartridge 200 reflected by the mirror portion 510 through the prism portion 500 from the front side of the aroma providing device 1. The material of the prism portion 500 is not particularly limited as long as it has transparency after formation. For example, the prism portion 500 may be formed of glass, quartz, transparent resin, etc.

[0060] Returning to FIG. 1 and FIG. 2, the rotary operation unit 600 is disposed on the outer periphery of the prism portion 500 and the fragrance cartridge 200. The rotary operation unit 600 has an integrated outer cylinder portion 610 and a holding portion 620. The outer cylinder portion 610 has an axial hole 611 in which the prism portion 500 is disposed, and is disposed on the outer periphery of the prism portion 500. The holding portion 620 has a cone-shaped portion 630 having a tapered shape expanding in diameter toward the front side, and an inner cylinder portion 640 connected to the rear end of the cone-shaped portion 630. The cone-shaped portion 630 is disposed on the outer periphery of the mirror surface portion 510 of the prism portion 500, and the inner cylinder portion 640 holds the fragrance cartridge 200 on its inner periphery. A positioning groove 641 is formed on the inner periphery of the inner cylinder portion 640, which is disposed continuously with the positioning groove 531 of the prism portion 500.

[0061] The case 210 of the fragrance cartridge 200 is provided with a protrusion 212 which serves as a positioning element when attaching the fragrance cartridge 200. The protrusion 212 is disposed in the positioning groove 531 of the prism portion 500 and the positioning groove 641 of the inner cylinder portion 640. This allows the fragrance cartridge 200 to be positioned relative to the rotation operation portion 600, and also allows the rotation operation portion 600 and the case 210 of the fragrance cartridge 200 to rotate integrally.

[0062] The base portion 740 has a support portion 750 and a base portion 760. The support portion 750 has a cylindrical shape. The base portion 760 is supported on the inner peripheral portion of the support portion 750 so as to be movable in the axial direction. The base portion 760 and the support portion 750 are connected by a heart cam mechanism 763, and the base portion 760 can be held in an advanced position and a retreated position relative to the support portion 750. In addition, the rear end portion of the flavoring cartridge 200 is rotatably supported on the inner peripheral portion of the support portion 750. Furthermore, the inner cylinder portion 640 of the holding portion 620 of the rotation operation unit 600 is rotatably supported on the front side of the inner peripheral portion of the support portion 750.

[0063] The support part 750 is provided with a piston 855 as an engagement element that can enter a recess 217 provided on the outer peripheral surface of the rear end part of the flavor cartridge 200. The piston 855 is biased toward the outer peripheral surface of the flavor cartridge 200 by a piston spring 853. As a result, while the flavor cartridge 200 is being rotated, the piston spring 853 contracts and the piston 855 retreats, and when any of the recesses 217 coincides with the position of the piston 855, the piston 855 enters the recess 217. This makes it possible to fix the flavor cartridge 200 in a predetermined rotational position and to give the user a sense of rotational operation.

[0064] The base portion 760 has a fixed shaft 761 extending forward. The fixed shaft 761 is inserted into the cylindrical portion 155 of the case cover 150 of the fragrance cartridge 200. An engagement portion (not shown) (part indicated by reference numeral 769 in FIGS. 26 and 27) is provided at the tip of the fixed shaft 761. The engagement portion engages with an engagement portion (not shown) formed in the cylindrical portion 155 of the case cover 150 of the fragrance cartridge 200, so that the relative rotation between the case cover 150 and the base portion 740 is restricted. As a result, the rotation operation portion 600 and the case 210 of the fragrance cartridge 200, which can rotate together, can rotate relative to the base portion 740.

[0065] The base portion 760 has an air supply port 765 penetrating therethrough in the axial direction. The air pump 840 is driven by power supplied from the battery 810 to introduce air into the air supply port 765. The air introduced into the air supply port 765 is supplied to one of the plurality of holding spaces 231 provided in the aromatic cartridge 200.

[0066] The base portion 760 also has a positioning protrusion 764. The protrusion 764 is capable of engaging with a locking groove (not shown) (a portion indicated by reference numeral 643 in FIG. 27) formed in the inner tube portion 640 of the rotation operation portion 600. Specifically, the protrusion 764 of the base portion 760 engages with the locking groove of the inner tube portion 640 of the rotation operation portion 600 when the base portion 760 is held by the support portion 750 in the forward position. The protrusion 764 of the base portion 760 is released from the engagement with the locking groove of the inner tube portion 640 when the base portion 760 is held by the support portion 750 in the backward position. This mechanism functions as a rotation lock mechanism that restricts the relative rotation between the rotation operation portion 600 and the base portion 740 when the aromatic cartridge 200 is removed from the aroma providing device 1. The rotation lock mechanism will be described in detail later.

[0067] The air pump 840 may be, for example, a diaphragm-type pump that deforms a diaphragm by supplying an alternating current to a piezoelectric element to suck and pump air. The battery 810 may be a replaceable battery that only discharges electricity, or a secondary battery that can be charged and discharged. The operation of the air pump 840 is controlled by operating the operation switch 730. For example, by pressing the operation switch 730, a switching element of the circuit board 820 is turned on and off, and power is supplied from the battery 810 to the air pump 840. As a result, air is supplied to the fragrance cartridge 200 via the air supply port 765.

[0068] For example, the power supply may be switched on and off each time the operation switch 730 is repeatedly pressed, or the power supply may be maintained in the on state while the operation switch 730 is being pressed. Other electronic components, such as a light source such as an LED (Light Emitting Diode) that indicates the operating state of the aroma provision device 1, may be mounted on the circuit board 820. In addition, a communication interface may be mounted on the circuit board 820 to enable the aroma provision device 1 to be operated by a remote controller, a smartphone, or the like.

[0069] The blowing source that supplies air toward the flavor cartridge 200 is not limited to the air pump 840, and may be, for example, a blower that rotates a fan. The blowing source that supplies air toward the flavor cartridge 200 does not have to be an electric type, and may be a manual type. When the blowing source is a manual type, the battery, the operation switch, and the circuit board may be omitted.

[0070] 23 and 24 are block diagrams showing an example of a system configuration of the aroma providing device 1. In the example of FIG. 23 and FIG. 24, the battery 810 is electrically connected to the air pump 840 via a circuit board 820 and a switching element 830. In response to the operation of the operation switch 730, the power of the battery 810 is supplied to the air pump 840. When the air pump 840 is driven and air is supplied to the holding space 231 of the aroma cartridge 200, the liquid aroma held in the aroma holder arranged in the holding space 231 is vaporized, and the aroma is released together with the air. In the example of FIG. 23, the rotation operation unit 600 is manually rotated, and the holding space 231 of the aroma cartridge 200 into which the air supplied from the air pump 840 is introduced can be switched.

[0071] 24, the battery 810 is electrically connected to a motor 850 that rotates the rotary operation unit 600 via a circuit board 820 and a switching element 835. For example, in response to a user's operation of a rotation changeover switch, power from the battery 810 is supplied to the motor 850, and the rotary operation unit 600 is rotated. In this manner, the holding space 231 of the fragrance cartridge 200 into which air supplied from the air pump 840 is introduced may be switchable.

[0072] (3.2. Rotational movement) Next, the rotational operation of the fragrance cartridge 200 in the fragrance provision device 1 will be described with reference to Fig. 2 and Fig. 25. Fig. 2 shows the fragrance provision device 1 in an unused state, and Fig. 25 shows the fragrance provision device 1 in an used state.

[0073] 2, when the aroma providing device 1 is not in use, the holding space 231 of the aroma cartridge 200 is not in communication with the air supply port 765, and the pseudo space 232 is aligned with the outlet of the air supply port 765. Since the second opening 151 of the case cover 150 is also located in the same phase as the air supply port 765, the pseudo space 232 is aligned with the second opening 151. As a result, all of the holding spaces 231 in which the aroma support 251 is arranged are not in communication with the air supply port 765 and the second opening 151, and release of the aroma is suppressed.

[0074] 25, when using the aroma providing device 1, the rotation operation unit 600 is rotated to rotate the aromatic cartridge 200 integrally, and the desired holding space 231e is connected to the air supply port 765 via the first opening 221e. At this time, the holding space 231e connected to the air supply port 765 is connected to the second opening 151 via the communication hole 101e. The user can operate the operation switch 730 to supply air from the air pump 840 to the holding space 231e, thereby vaporizing the liquid aromatic held in the aromatic holder 251 (not shown) arranged in the holding space 231e and releasing it together with the air.

[0075] (3.3. Rotation lock mechanism) Next, the rotation lock mechanism of the aroma provision device 1 will be described with reference to Fig. 26 and Fig. 27. Fig. 26 and Fig. 27 are perspective views showing only the holding part 620 of the rotation operation part 600 and the base part 760 of the base part 740, and Fig. 27 shows a state in which the holding part 620 and the base part 760 are rotated by 90 degrees relative to each other from the state shown in Fig. 26.

[0076] As described above, the positioning groove 641 is formed on the inner periphery of the inner cylinder 640 of the holding part 620. The engagement groove 643 is formed on the outer periphery of the inner cylinder 640 at a position rotated 180 degrees from the position where the positioning groove 641 is provided. The protrusion 764 provided on the base 760 of the base part 740 can be engaged with the engagement groove 643. As described above, the base 760 of the base part 740 is supported by the heart cam mechanism 763 so as to be movable in the axial direction on the inner periphery of the support part 750. When the base 760 moves forward, the protrusion 764 of the base 760 enters and engages with the engagement groove 643 of the holding part 620, and when the base 760 moves rearward, the engagement between the protrusion 764 and the engagement groove 643 is released. 26 and 27 show a state in which the base portion 760 has moved rearward and the engagement between the protrusion 764 and the engagement groove portion 643 has been released.

[0077] The operation of the rotation lock mechanism will be specifically described with reference to Figures 28 and 29. Figure 28 is an axial cross-sectional view of the tip of the aroma provision device 1, and Figure 29 is a perspective view showing only the holding part 620 of the rotation operation part 600 and the base part 760 of the base part 740, showing a perspective view of the holding part 620 and the base part 760 shown in Figure 28 from below. In each of Figures 28 and 29, the upper part shows a state in which the aromatic cartridge 200 is attached to the device main body 700, and the lower part shows a state in which the aromatic cartridge 200 is removed from the device main body 700.

[0078] 28 and 29, when the aromatic cartridge 200 is attached to the device main body 700, the base part 760 is held in a retracted position by the heart cam mechanism 763. At this time, the engagement between the protrusion 764 of the base part 760 and the engagement groove part 643 of the inner cylinder part 640 of the holding part 620 is released. Therefore, the holding part 620 becomes rotatable relative to the base part 760, and the aromatic cartridge 200, which rotates integrally with the rotation operation part 600, becomes rotatable relative to the device main body 700.

[0079] On the other hand, as shown in the lower part of Figures 28 and 29, when the aromatic cartridge 200 is removed from the device main body 700, the heart cam mechanism 763 holds the base part 760 in the forward position. At this time, the protrusion 764 of the base part 760 is engaged with the engagement groove part 643 of the inner cylinder part 640 of the holding part 620. Therefore, relative rotation between the holding part 620 and the base part 760 is not possible, and when the aromatic cartridge 200 is removed, the holding part 620 is held in a predetermined rotational position. This allows the aromatic cartridge 200 to be easily removed from the device main body 700 by adjusting it to the predetermined rotational position.

[0080] (3.4. Rotation restriction mechanism) Next, a description will be given of a rotation restriction mechanism between the case 210 and the case cover 150 of the fragrance cartridge 200. The fragrance cartridge 200 according to this embodiment has a rotation restriction mechanism that restricts the relative rotation between the case 210 and the case cover 150 when the fragrance cartridge 200 is not attached to the device main body 700.

[0081] 6, the engaging protrusion 159 formed on the rear end surface of the disk portion 153 of the case cover 150 is inserted into the communication hole 101c of the second case body 100. In this state, the rotation of the case cover 150 relative to the case 210 is restricted.

[0082] Fig. 30 is a diagram for explaining the operation of the rotation restriction mechanism when the aromatic cartridge 200 is attached to the device main body 700. As described above, when the case cover 150 and the case 210 are assembled, the locking claws 156 provided on the outer periphery of the cylindrical portion 155 of the case cover 150 are locked to the step portion between the small diameter portion 111a and the large diameter portion 111b of the axial hole 111 provided in the second case body 100. At this time, a gap S at least equal to or greater than the height of the engaging protrusion 159 is formed between the locking claws 156 and the step portion (see the diagram shown in the upper part of Fig. 30).

[0083] When the aromatic cartridge 200 is attached, an engagement portion 769 provided at the tip of the fixed shaft 761 of the base portion 760 is inserted into an engagement recess 157 provided at the bottom of the internal space of the cylindrical portion 155 of the case cover 150. At this time, for example, the engagement portion 769 is lightly pressed into the engagement recess 157, and the case cover 150 moves forward by the length of the above-mentioned gap S. As a result, the engagement protrusion 159 of the case cover 150 shown in FIG. 6 moves forward beyond the communication hole 101c, and the case cover 150 becomes rotatable relative to the case 210. This allows the case 210 to rotate when the aromatic cartridge 200 is attached to the device main body 700.

[0084] With this rotation restriction mechanism, when the fragrance cartridge 200 is not in use, the rotational position of the second opening 151 of the case cover 150 is aligned with the arrangement position of the pseudo space 232 of the case 210, so that any of the holding spaces 231 in which the fragrance holder 251 is arranged is not opened to the outside through the second opening 151. Therefore, leakage of the fragrance can be suppressed when the fragrance cartridge 200 is not in use.

[0085] The engaging protrusion 159 and the communication hole 101 constituting the rotation restriction mechanism are an example of an engaging portion and an engaged portion, and the engaging portion and the engaged portion are not limited to such an example. The engaging portion and the engaged portion may be in an engaged state before the flavor cartridge 200 is attached to the device main body 700, and may be disengaged after the flavor cartridge 200 is attached to the device main body 700.

[0086] <4. Manufacturing method of fragrance cartridge (fragrance holding structure)> Next, an example of a manufacturing method for the fragrance cartridge 200 according to this embodiment shown in Figs. 3 to 6 will be described. The manufacturing method for the fragrance cartridge 200 according to this embodiment includes first to fourth steps. Hereinafter, the manufacturing method for the fragrance cartridge 200 will be described in the order of steps with reference to Figs. 31 to 33. Figs. 31 to 33 are schematic diagrams showing a portion of one of the multiple holding spaces 231 constituting the fragrance cartridge 200.

[0087] (4.1. 1st step) In the first step, the first case body 211 illustrated in Figs. 8 to 10 is produced. A plurality of holding spaces 231 and pseudo spaces 232 are formed in the first case body 211. A first rib 235 is formed on the rear end side of each holding space 231, and the holding space 231 is divided into a ventilation area A in which the first opening 221 is provided, and a holding area F that is disposed adjacent to the ventilation area A and communicates with the ventilation area A. The method of producing the first case body 211 is not particularly limited, but for example, it can be molded by pouring a molten resin material into a mold and solidifying it. The resin material used is not particularly limited, but it is preferable that the resin material is resistant to the liquid fragrance.

[0088] (4.2.2nd step) In the second step, the fragrance holder 251 is accommodated in the holding area F of the first case body 211. For example, as shown in FIG. 31, the fragrance holder 251, which has already held a liquid fragrance, is inserted into the holding area F of each holding space 231. At this time, the rear end of the fragrance holder 251 is inserted into the recess 237 formed by the first rib 235. The liquid fragrances held in the fragrance holders 251 accommodated in each holding space 231 may all be the same, or may be partially or completely different.

[0089] In the second step, the impregnating material before holding the liquid flavor may be inserted into the holding area F, and then the liquid flavor may be dropped in to impregnate the impregnating material with the liquid flavor.

[0090] (4.3. 3rd step) In the third step, the case 210 is produced by attaching the second case body 100 to the first case body 211 in which the aromatic material holders 251 are arranged in all of the holding spaces 231. For example, as shown in Fig. 32, the second case body 100 has a plurality of communication holes 101 communicating with each of the holding spaces 231 of the first case body 211, and a second rib 121 standing in each of the holding spaces 231. By attaching the second case body 100 to the first case body 211, the movement of the aromatic material holders 251 towards the ventilation area A is restricted by the first rib 235 and the second rib 121.

[0091] (4.4. 4th step) In a fourth step, the case cover 150 having the second opening 151 is attached to the case 210. As shown in FIG. 33, the case cover 150 is provided with one second opening 151, and the case cover 150 and the case 210 are attached to be capable of relative rotation. Therefore, by switching the rotational position of the case cover 150 with respect to the case 210, the second opening 151 can communicate with any of the holding spaces 231 via the communication hole 101. Although not shown, during manufacturing, the second opening 151 may be attached to a position corresponding to the pseudo space 232 provided in the first case body 211. This prevents the scent from leaking from any of the holding spaces 231 when the fragrance cartridge 200 is not in use.

[0092] As described above, according to the fragrance cartridge 200 of this embodiment, the holding space 231 in which the fragrance support 251 is arranged in the fragrance cartridge 200 has a ventilation area A that can face the first opening 221 and the second opening 151, and a holding area F that is arranged adjacent to the ventilation area A and communicates with the ventilation area A and in which the fragrance support 251 is arranged. The fragrance cartridge 200 includes a first rib 235 as a restricting part that restricts the movement of the fragrance support 251 toward the ventilation area A, a recess 237 formed by the first rib 235, and a second rib 121. Therefore, it is possible to reduce the risk that the fragrance support 251 will enter the ventilation area A and obstruct the flow of air passing through the ventilation area A. Therefore, the ventilation resistance of the air passing through the ventilation area A is reduced, and the decrease in the flow rate of the fragrance released from the fragrance providing device 1 can be suppressed.

[0093] In addition, in the flavor cartridge 200 according to this embodiment, the regulating portion is composed of the first rib 235 and the second rib 121 formed on the first case body 211 and the second case body 100. Therefore, when manufacturing the flavor cartridge 200, the flavor holder 251 is appropriately arranged in the holding space 231, and the first case body 211 and the second case body 100 are appropriately assembled, so that a structure for restricting the movement of the flavor holder 251 can be easily formed. In particular, the flavor cartridge 200 according to this embodiment has a plurality of holding spaces 231 in which the flavor holder 251 is arranged. Therefore, it is significant that the flavor holder 251 is appropriately arranged in the holding space 231, and the first case body 211 and the second case body 100 are appropriately assembled, so that a structure for restricting the movement of the flavor holder 251 in each holding space 231 can be easily formed.

[0094] Moreover, in the fragrance cartridge 200 according to this embodiment, the case cover 150 has an engagement protrusion 159 that engages with the communication hole 101c of the second case body 100 when the fragrance cartridge 200 is not attached to the device main body 700 and that is disengaged from the communication hole 101c of the second case body 100 when the fragrance cartridge 200 is attached to the device main body 700. Therefore, when the fragrance cartridge 200 is not in use, it is possible to maintain the retention space 231 in which the fragrance retainer 251 is arranged as a closed space, and it is possible to prevent the fragrance from leaking out when the fragrance cartridge 200 is not in use.
