Description

Technical Field

[0001] The present invention relates to a scent display device that sprays air containing a scent, and more particularly to an intensifier device for expanding the range of air reaching the scent display device. This application claims priority based on Japanese application No. 2022-112399 filed on July 13, 2022, and all the records of the above Japanese application are hereby cited by reference. Background Art

[0002] The existing device is used together with a device that can play images and sounds, such as a television, a personal computer, a game console, etc., to produce a fragrance in accordance with the scene. In this specification, such a device that produces a fragrance in accordance with the scene is called a fragrance display. In particular, it is known that when fragrance is used in virtual reality, the following effects can be produced: the user can not only feel the fragrance of the object, but also can feel a sense of speed due to the brain function associated with the sense of smell, for example.

[0003] When the fragrance is appropriately produced in accordance with the scene, it is necessary to switch the fragrance accurately. Therefore, a fragrance display device is needed that can emit the desired fragrance to a limited range at any time, and eliminate the fragrance at any time and switch to the next fragrance. On the other hand, it is envisioned that the fragrance display device is targeted at a specific person so that he or she can feel the fragrance. Therefore, it is hoped that the fragrance display device is smaller and the sound when the fragrance is sprayed is also smaller. In such a fragrance display device, it is difficult to spray air with the momentum of causing the fragrance remaining in the surrounding to dissipate immediately.

[0004] In order to solve such a problem, the power of the spraying mechanism of the fragrance can be increased. However, if you want to increase the power used for the fragrance spraying, it is inevitable that the fragrance display device will increase, and there will be a problem that the noise during the action also increases.

[0005] A solution to such a problem is proposed in Patent Document 1 described later. Patent Document 1 proposes an enhancer device that does not increase the fragrance ejection power of the fragrance display and can eject air with a power greater than that of the fragrance display. The enhancer device accommodates the fragrance display inside a housing, and uses an axial flow fan (propeller fan) provided in the enhancer device to generate a flow of air passing around the fragrance display. The fragrance display can be removed from the enhancer device at any time. Therefore, when it is not necessary to diffuse the fragrance over a wide range, only the fragrance display is used, and when it is necessary to diffuse the fragrance over a wide range or to dissipate the fragrance immediately, the fragrance display and the enhancer device can be used in combination.

[0006] According to the booster device disclosed in Patent Document 1, in a fragrance display device that can emit fragrance with only a small power by itself, it is possible to send fragrance to a farther distance by a larger air flow (air volume).

[0010] 1. Technical issues to be resolved

[0011] However, the intensifier device disclosed in Patent Document 1 has a problem of being large-scale. Therefore, when an individual uses the fragrance display device, the intensifier device must be removed. In addition, with respect to the intensifier device disclosed in Patent Document 1, even if it is desired to send air at a higher power, due to the characteristics of the axial flow fan, although more air flow (air volume) can be obtained, the force (static pressure) for pushing out the air cannot be sufficiently obtained, and therefore there is also a problem that the expected degree of fragrance spray distance cannot be achieved.

[0012] Therefore, an object of the present invention is to provide an enhancer device for a fragrance display which is compact even when combined with the fragrance display and which enables the fragrance to reach a distant place.

[0055] In the following description and drawings, the same reference numerals are given to the same components, and therefore, detailed description thereof will not be repeated.

[0056] 1. First Implementation Method

[0057] A. Aroma display system 50

[0058] Figure 1 1 is a perspective view of a fragrance display system 50 according to a first embodiment of the present invention. Figure 1 The aroma display system 50 includes: an aroma display 60; an intensifier 62, which is used to hold the aroma display 60 and form an air flow, and the air flow is used to transport the air sprayed by the aroma display 60 to a distant place; and a support 68, which has an intensifier locking member 70, the intensifier locking member 70 clamps the intensifier 62 and is connected to the internal thread portion ( Figure 1 The support 68 holds the fragrance display 60 and the intensifier 62 so that they can swing around the rotation axis defined by the intensifier lock 70. The internal thread portion constitutes an engagement portion, which is used to engage the fragrance display 60 with the intensifier lock 70, but also has the function of fixing the fragrance display 60 to a commercially available tripod or the like.

[0059] As described later, the aroma display 60 has an upper surface and a bottom surface, both of which are regular hexagonal in shape. An opening 64 is formed in the center of the upper surface of the aroma display 60, and air containing aroma is ejected from the opening 64. The enhancer 62 has a duct 130 that serves as an air passage. The duct 130 is formed along the side of the aroma display 60. The duct 130 has an opening 66 that serves as an air ejection port at a position substantially at the same height as the outer periphery of the upper surface of the aroma display 60.

[0060] Reference Figure 2 The enhancer 62 includes: a holder 100, which holds the bottom surface of the aroma display 60 and the outer periphery of the aroma display 60 near the bottom surface; a substrate 102, which is mounted on the bottom surface of the holder 100; and a fan assembly 104, which is accommodated in a space formed at the bottom of the holder 100 and is used to open to the bottom surface side of the duct 130 ( Figure 2 The intensifier 62 further includes a bottom plate 106, and the bottom plate 106 is engaged with the bottom side end surface of the retaining frame 100.

[0061] The base plate 102 has a pin electrically connected to a connection portion formed on the bottom surface of the aroma display 60 mounted on the holder 100. The base plate 102 is used to receive power supply and control signals from the aroma display 60 to the fan assembly 104 via the pin. The base plate 102 is screwed to the lower surface of the holder 100 by a small screw.

[0062] The fan assembly 104 includes: a centrifugal fan 112 for generating a flow of air to be sent into the interior of the duct 130; and an air guide duct 114 having a first opening fixed to the discharge port of the centrifugal fan 112 and a second opening connected to the bottom surface side opening of the duct 130. The centrifugal fan 112 is configured in such a manner that the impeller of the centrifugal fan 112 rotates around an axis parallel to the central axis of the aroma display 60. The discharge port of the centrifugal fan 112 faces a direction located in a position twisted with the central axis of the centrifugal fan 112. The air guide duct 114 is used to change the flow of air blown from the discharge port of the centrifugal fan 112 toward the side of the retaining frame 100 by 90 degrees and send it into the interior of the duct 130. The centrifugal fan 112 and the air guide duct 114 are screwed to the bottom surface of the retaining frame 100 by small screws.

[0063] A plurality of air inlets for the centrifugal fan 112 are formed on the bottom plate 106. The bottom plate 106 is threadedly fixed to the bottom surface of the holder 100 by means of small screws 110. In addition, an opening is formed on the bottom plate 106 and the holder 100, and when the bottom plate 106 is fixed to the holder 100, the opening passes from the lower surface of the bottom plate 106 to the upper surface of the portion of the holder 100 that accommodates the aroma display 60. In addition, an internal thread portion serving as an engaging portion with the support 68 is formed at the same position on the bottom surface of the aroma display 60. The long screw 108 is passed through the opening from the bottom plate 106 side and passes to the inside of the holder 100, and is engaged with the internal thread portion of the bottom surface of the aroma display 60, thereby fixing the bottom plate 106, the fan assembly 104, the holder 100 and the aroma display 60 integrally.

[0064] The support 68 includes: a bottom 120 which is in a regular hexagonal shape and in stable contact with the plane, and a locking retainer plate 122 which is vertically erected from one side of the outer periphery of the bottom 120. Figure 2 The intensifier locking member 70 (see Figure 1 ). The structure of the locking retainer plate 122 will be described later. Six magnets 124 are embedded in the lower surface of the bottom 120. As a result, the aroma display system 50 can be configured and fixed in various positions by adsorbing the support 68 to the side plate of a steel cabinet or the like.

[0065] Reference Figure 3An opening (not shown) is formed near the upper end of the locking retaining frame plate 122 of the support 68, and the enhancer locking piece 70 is installed in the opening. As described later, the enhancer locking piece 70 clamps the enhancer 62 and has an external threaded portion, which engages with an internal threaded portion provided on the side of the fragrance display 60. By screwing the external threaded portion of the enhancer locking piece 70 with the internal threaded portion of the fragrance display 60, the fragrance display 60 and the enhancer 62 are screwed to the support 68. In addition, by loosening the enhancer locking piece 70, the fragrance display 60 and the enhancer 62 can be centered on the rotation axis of the enhancer locking piece 70, as shown in FIG. Figure 3 In this embodiment, the height of the enhancer locking member 70 from the bottom 120 is selected so that when the fragrance display 60 and the enhancer 62 are installed, they can only rotate within a certain angle range.

[0066] B. Aroma Display 60

[0067] Reference Figure 4 and Figure 5 , the aroma display 60 has: a first surface, i.e., an upper surface 74, and a second surface, i.e., a lower surface 72, having substantially the same regular hexagonal outer periphery; and a third surface, i.e., a side surface 82, connecting the outer periphery of the lower surface 72 with the outer periphery of the upper surface 74. Therefore, the aroma display 60 is roughly in the shape of a regular hexagonal prism. That is, the side surface 82 has six surfaces, i.e., the first surface to the sixth surface. The aroma display 60 has a central axis 86, which connects the geometric center of the hexagon of the lower surface 72 with the geometric center of the hexagon of the upper surface 74. The aroma display 60 has a six-fold rotationally symmetrical appearance with the central axis 86 as the rotation axis.

[0068] The first surface of the side surface 82 is formed with an internal thread portion 76, and the external thread portion of the enhancer locking member 70 is engaged with the internal thread portion 76. A position limiting portion 80 is formed in a portion continuous from the bottom surface of the first surface. The position limiting portion 80 is a cutout for limiting the position of the fragrance display 60 when the fragrance display 60 is installed on the enhancer 62 so that the internal thread portion 76 faces the correct direction. The position limiting component formed on the enhancer 62 is engaged with the position limiting portion 80 to limit the position of the fragrance display 60, and the fragrance display 60 is installed at the standard position of the enhancer 62.

[0069] A USB (Universal Serial Bus)-C connector 78 is provided on the second side surface 82 for the fragrance display device 60 to receive control signals and power supply from the outside. The fragrance display device 60 stores six fragrance boxes (not shown) and has the function of blowing the fragrance from the box specified by the control signal from the opening 64.

[0070] Special reference Figure 5 The lower surface 72 of the aroma display device 60 is formed with Figure 2 The substrate 102 is shown connected to the connection portion 84. The signal for controlling the centrifugal fan 112 and the power received via the USB-C connector 78 are provided to the fan assembly 104 via the connection portion 84 and the substrate 102 for driving the centrifugal fan 112.

[0071] C. Enhancer 62

[0072] Reference Figures 6 to 11 The holder 100 of the enhancer 62 includes: a display holder portion 132, which is used to hold the lower surface 72 of the fragrance display 60 and the side surfaces 82 thereof; and a fan cover 134, which is connected to the display holder portion 132 at the lower portion of the display holder portion 132 and is used to accommodate the fan assembly 104.

[0073] The display holder portion 132 is divided from the fan housing 134 by a dividing plate 138. An outer peripheral wall 136 is formed on three adjacent sides of the outer periphery of the dividing plate 138. Side walls 202 and 204 are formed on the sides adjacent to the side on which the outer peripheral wall 136 is formed, respectively, from the outer peripheral wall 136. The duct 130 is provided on the remaining side sandwiched by the side walls 202 and 204, and the outer wall of the duct 130 divides the inside of the duct 130 and the display holder portion 132. The duct 130 has: an opening (not shown) formed in a portion that is in contact with the outer periphery of the second surface, i.e., the lower surface side, of the fragrance display 60 when the fragrance display 60 is stored in the display holder portion 132; and an opening 66 that is provided in contact with the side that connects the upper ends of the side walls 202 and 204. The upper end of the duct 130 is substantially at the same height as the upper ends of the side walls 202 and 204. The opening 66 formed at the upper end of the duct 130 is substantially at the same height as the first surface, ie, the upper surface, of the fragrance display 60 when the fragrance display 60 is stored in the display holder 132.

[0074] Reference Figure 7 and Figure 8 The opening 66 formed at the upper end of the duct 130, i.e., the upper surface side of the aroma display 60, has a substantially trapezoidal cross-sectional shape. A duct bottom opening 300 is formed at the lower end of the duct 130, i.e., the lower surface side of the aroma display 60. The duct bottom opening 300 has the same shape and the same size (area) as the opening 66. Figure 2 The air guide duct 114 is connected as shown. Figure 6As shown in FIG. 1 , the duct 130 is perpendicular to the bottom surface of the intensifier 62 and is arranged straightly along the side surface of the intensifier 62. Therefore, the shape of the internal space of the duct 130 is a prism with an opening 66 and a duct bottom opening 300 as two ends and a substantially trapezoidal cross-sectional shape. That is, the cross-sectional shape and area of ​​the duct 130 in a plane perpendicular to the extending direction of the duct 130 are the same over the entire length of the duct 130. The air from the centrifugal fan 112 is introduced into the opening on the side of the air guide duct 114 opposite to the duct 130 side, thereby guiding the air into the duct 130.

[0075] A pin opening 260 is formed in the central portion of the partition plate 138. Figure 2 The pin 210 of the substrate 102 shown in FIG. Figure 6 ) is inserted from the lower surface of the partition plate 138 toward the upper surface. The pin 210 and Figure 5 The illustrated connection 84 is electrically connected to provide control signals from the aroma display 60 to the fan assembly 104 via the base plate 102 .

[0076] Reference Fig. 9 , inside the duct 130, three rectifying plates 250, 252, and 254 are arranged along the direction of travel of the air in the duct 130. These rectifying plates are arranged at a certain interval and in parallel with each other. By arranging such rectifying plates in the duct 130, the centrifugal fan 112 has an exhaust port facing a direction different from the extension direction of the duct 130. In this embodiment, it is necessary to bend the flow of air sent out from the centrifugal fan 112 90 degrees in the direction of the duct 130. In addition, in order to introduce the flow of air sent out from the centrifugal fan 112 into the duct 130, it is necessary not only to bend the direction of the flow of air by 90 degrees, but also to diffuse it in the left and right directions. Therefore, the air introduced into the duct 130 is turbulent. By arranging rectifying plates 250, 252, and 254 inside the duct 130, the flow of air can be adjusted in the duct, and as a result, the air containing fragrance can be guided to a distant place.

[0077] Reference Fig.10 A locking opening 206 is formed in the side wall 202 of the display holder 132. A position limiting member 208 is provided on the inner peripheral surface of the side wall 202 directly below the locking opening 206. The position limiting member 208 is connected to the position limiting member 80 (see FIG. 1 ) provided on the fragrance display 60. Figure 4 and Figure 5 ) is engaged to limit the position of the fragrance display 60. The fragrance display 60 is inserted into the display holder portion 132 by engaging the position limiting member 208 with the position limiting portion 80, so that the locking opening 206 is engaged with the position limiting portion 80. Figure 4 and Figure 5The internal threaded portion 76 shown is opposite. Therefore, it is possible to make the external threaded portion 400 (refer to Fig.15 ) passes through the locking opening 206 and is screwed into the internal thread portion 76. As a result, the fragrance display 60 and the enhancer 62 can be fixed to the support 68 in a manner that the fragrance display 60 and the enhancer lock 70 clamp the holder 100.

[0078] The fan housing 134 is formed to be connected to the lower portion of the outer peripheral wall 136 , and the inside of the fan housing 134 is a fan housing portion 320 for housing a fan (not shown).

[0079] D. Air duct 114

[0080] Reference Figure 12 to Figure 14 The air duct 114 includes a frame 330, the frame 330 having: a front surface 340, which is formed with the centrifugal fan 112 (refer to Figure 2 ) is connected to the fan side opening 342 of the air outlet; the side wall 348; the back 366; the side 364, which is connected between the side wall 348 and the back 366; and the upper partition 356. The front surface 340 is also formed with a screw chamber 352 separated from the fan side opening 342 by the central partition 350. The bottom surface of the screw chamber 352 and the upper partition 356 are respectively formed with screw holes 354 and 362. The screw holes are used to Figure 2 A long screw 108 is shown passing through.

[0081] A duct side opening 358 is formed on the upper surface of the air guide duct 114, and the duct side opening 358 is connected to the duct bottom opening 300 of the duct 130. The fan side opening 342 and the duct side opening 358 are surrounded by the bottom plate 344, the side walls 346 and 347, and the lower surface of the upper partition 356, which are part of the frame 330, so as to guide the flow of the air discharged from the centrifugal fan 112 to the duct bottom opening 300 (see Fig.10 and Fig.11 A snap-fitting part 360 is formed around the duct side opening 358. The snap-fitting part 360 is snap-fitted with the duct bottom opening 300 of the duct 130, so that the air guide duct 114 is connected to the duct bottom opening 300 without a gap.

[0082] Especially if Fig.14 As shown, the bottom plate 344 and its back side 366 are formed into a streamlined shape without a height difference. Therefore, the energy loss of the air flow discharged from the centrifugal fan 112 can be minimized, and the direction of the air flow can be changed by 90 degrees and guided to the inside of the duct 130. As a result, the maximum wind force and maximum static pressure of the centrifugal fan 112 can be effectively utilized to transport the air containing the fragrance to a distant place, and the fragrance floating around can be dissipated.

[0083] E. Support 68

[0084] Reference Fig.15 As described above, the support 68 includes a bottom 120 and a locking and holding frame plate 122. The bottom 120 is a regular hexagon having an opening 402 inside. The locking and holding frame plate 122 is erected in a manner extending perpendicularly to a plane defined by the regular hexagon of the bottom 120 from the outside of one side of the regular hexagon of the bottom 120. The top end of the locking and holding frame plate 122 is formed in a semicircular shape. The external threaded portion 400 of the enhancer locking piece 70 is mounted on the locking and holding frame plate 122 in a manner that passes through the center portion of the semicircular shape. The enhancer locking piece 70 can rotate freely relative to the locking and holding frame plate 122. By screwing the external threaded portion 400 of the enhancer locking piece 70 with the internal threaded portion 76 of the fragrance display 60 provided on the enhancer 62, the fragrance display 60 and the enhancer 62 can be held by the support 68. If the enhancer lock 70 is slightly loosened, the fragrance display 60 and the enhancer 62 can be rotated within a certain angle range relative to the support 68, and the enhancer lock 70 can be tightened at the rotated position, so that the fragrance display 60 and the enhancer 62 can be fixed at the rotated angle.

[0085] like Figure 2 As shown, six magnets 124 are embedded and fixed in the back of the bottom 120. Therefore, by making the support 68 adsorb to the steel part like the door of a cabinet, the posture of the fragrance display device 60 and the booster 62 can be freely set.

[0086] F. Action

[0087] Reference Figures 1 to 15 , the aroma display system 50 performs the following actions. Figure 1 The aroma display 60 responds to a control signal provided from the outside and ejects air containing any combination of the six aromas from the opening 64 at a time specified by the control signal. The ejection force of the aroma display 60 is relatively small. Therefore, the ejected aroma-containing air only reaches the vicinity of the aroma display 60.

[0088] When the fragrance is to be diffused to a larger area, the centrifugal fan 112 of the enhancer 62 is started according to the time when the fragrance display device 60 sprays the air containing the fragrance (see Figure 2). The air discharged laterally by the centrifugal fan 112 is changed into an upward flow by the air guide duct 114 and guided to the duct bottom opening 300 of the duct 130. The air introduced into the interior of the duct 130 via the duct bottom opening 300 directly flows upward inside the duct 130 and is blown out from the uppermost opening 66. The flow of air generated by the centrifugal fan 112 and blown out from the duct 130 is stronger and faster. Therefore, the air blown out from the duct 130 also brings in the surrounding air and reaches a distant place. The air containing fragrance that only reaches the vicinity of the fragrance display 60 is also brought in by the flow of air blown out from the duct 130 and transported to a distant place. As a result, the fragrance sprayed from the fragrance display 60 can reach a farther distance, especially compared with the case where the enhancer 62 is not used.

[0089] Sometimes, the aroma display 60 sprays another aroma after spraying one aroma. At this time, if the previous aroma remains, it will be mixed with the next aroma, and the desired effect cannot be achieved. At this time, the booster 62 is also started. By starting the booster 62, the air containing the aroma remaining in the vicinity of the aroma display 60 is blown away to a position away from the aroma display 60. By spraying a new aroma from the aroma display 60 after the booster 62 stops, it is possible to prevent the new aroma from mixing with the previous aroma, and the desired effect of the aroma can be achieved.

[0090] In addition, regarding the enhancer 62, the air blown out from the centrifugal fan 112 is completely introduced into the duct 130 via the air guide duct 114 and the duct bottom opening 300 of the duct 130, and is ejected from the opening 66. In the air passage formed by the air guide duct 114 and the duct 130, there is no obstruction to the flow of air. Therefore, there is no loss of power given to the air by the centrifugal fan 112, and the air is blown out from the opening 66. Therefore, the air ejected from the fragrance display 60 can be transported to a sufficiently far distance, and the air containing fragrance remaining near the fragrance display 60 can be immediately dissipated. As a result, even if a relatively compact centrifugal fan is used as the centrifugal fan 112, the above-mentioned effect can be fully obtained. It is not necessary to increase the size of the enhancer 62, and compactness can be achieved. In addition, the operating sound of the centrifugal fan 112 can also be reduced.

[0091] As described above, in the first embodiment, the aroma display 60 is not provided in the flow of the air exhausted from the centrifugal fan 112, but a duct is provided only along a portion of the outer peripheral wall of the aroma display 60, and air is exhausted from the duct. When the aroma display 60 ejects air containing aroma from the opening 64 formed in the central portion of the aroma display 60, the air containing aroma is transported to a distant place along with the flow of the air exhausted from the duct 130.

[0092] Regarding the intensifier disclosed in Patent Document 1, the air discharged from the axial flow fan collides with the bottom surface of the fragrance display device, and then flows around the bottom surface and toward the discharge port of the intensifier. Therefore, regarding the intensifier disclosed in Patent Document 1, it is believed that the power of the axial flow fan is not fully used to generate the flow of air.

[0093] In contrast, in the present embodiment, the air discharged from the centrifugal fan will not be obstructed by the aroma display 60 and can be blown out smoothly from the duct 130. Therefore, the power of the centrifugal fan is fully used to generate the flow of air and obtain the maximum static pressure. As a result, the air containing the fragrance ejected from the aroma display 60 is also efficiently brought into the flow of the air and transported to a distant place. In addition, the centrifugal fan is arranged in the fan cover 134 on the bottom side of the aroma display 60, and the duct 130 is also only arranged on a part of the periphery of the aroma display 60. As a result, the effect of making the enhancer 62 compact can also be obtained. As described above, compared with the enhancer disclosed in patent document 1, a smaller centrifugal fan can be used to obtain the same or higher maximum static pressure. Therefore, a significant effect of making the enhancer 62 compact can be further obtained.

[0094] 2. Second Implementation

[0095] Fig.16 The following is an overview of the structure of a fragrance presentation system 450 according to a second embodiment of the present invention. Fig.16 , aroma display system 450 and Figure 2 The first difference of the aroma display system 50 of the first embodiment shown is that an aroma display 460 is used instead of the aroma display 60, and a metal such as steel that is attracted by a magnet is installed at an appropriate position on the bottom surface of the aroma display 460.

[0096] The second difference is that the intensifier 462 is included, and instead of the holder 100, the intensifier 462 has a holder 470, and a plurality of magnets 472, 474 and 476 for fixing the aroma display 460 are provided in the display holder portion 132. Figure 2 The situation is different, that is, there is no need to fix the aroma display device 60 by the long screw 108. In this second embodiment, no Figure 2 The long screws 108 are shown, while small screws 490 are used to secure the base plate 106 to the lower end of the retaining frame 470.

[0097] In addition to the above differences, the aroma display system 450 has the same structure as the aroma display system 50 of the first embodiment. The only difference is how to fix the aroma display device to the holder. Therefore, in this second embodiment, the same effect as the first embodiment can also be obtained.

[0098] 3. Third Implementation Method

[0099] Fig.17 and Fig.18 2 shows a front view and a side view of a fragrance display system 550 according to a third embodiment of the present invention. Fig.17 and Fig.18 In the embodiment, the support 68 is not shown. However, Fig.18 As shown, an opening is also formed on the holder of the aroma display system 550 at a position opposite to the internal threaded portion of the aroma display device 60. Therefore, the aroma display system 550 can also be combined with the support 68.

[0100] The first difference between the aroma display system 550 and the aroma display system 50 of the first embodiment is that, instead of the holder 100 of the first embodiment, the aroma display system 550 includes a holder 560 without a fan cover. However, this difference is not an essential difference, and a fan cover 134 may also be provided in this embodiment. Similar to the duct 130 of the first embodiment, the holder 560 also has a duct 566, which extends from the bottom surface of the holder 560 to its upper end along the side surface corresponding to one side of the outer diameter of the hexagonal prism of the holder 560. The duct 566 has openings of the same shape at its lower end and upper end, which are omitted in the figure.

[0101] The second difference is that the centrifugal fan 112 of the aroma display system 50 is replaced with a centrifugal fan 562, and the centrifugal fan 562 is configured so that the rotation axis is perpendicular to the central axis of the aroma display 60. By configuring the centrifugal fan 562 in this way, the exhaust port of the centrifugal fan 562 is oriented in a direction perpendicular to the central axis of the aroma display 60.

[0102] The third difference is that, instead of the air guide duct 114 of the first embodiment, an air guide duct 564 is included for guiding the air exhausted from the centrifugal fan 562 to the lower opening of the duct 566. The function of the air guide duct 564 is the same as that of the air guide duct 114.

[0103] Reference Fig.19 and Fig. 20 The air guide duct 564 is a part of the fan mounting component 600 which is integrally formed of synthetic resin. In addition to the air guide duct 564, the fan mounting component 600 also includes: a retainer receiving portion 620 connected to the bottom of the retainer 560 and having a regular hexagonal shape, and a fan mounting plate 622 mounted in a manner perpendicular to the bottom of the retainer receiving portion 620. Screw holes are formed in the fan mounting plate 622, and the centrifugal fan 562 (see FIG. 1 ) can be screwed in. Fig.17 and Fig.18 ) is fixed to the fan mounting plate 622.

[0104] In this embodiment, the air guide duct 564 is formed at the bottom of the holder receiving portion 620 along a portion of the fan mounting plate 622. The air guide duct 564 has: a duct side opening 614 formed at a position flush with the upper end of the holder receiving portion 620; and a fan side opening 604 formed to be connected to the air exhaust port of the centrifugal fan 562 fixed to the fan mounting plate 622.

[0105] More specifically, the air duct 564 includes a side wall 610, a side wall 608 formed along the fan mounting plate 622, a bottom surface 606, and an upper surface 612. The fan-side ends of the side walls 610 and 608, the bottom surface 606, and the upper surface 612 define the periphery of the fan-side opening 604. On the other hand, the periphery of the duct-side opening 614 is defined by the upper end of the bottom surface 606, the upper ends of the side walls 610 and 608, and one side of the hexagon of the retainer receiving portion 620.

[0106] As described above, the function of the air guide duct 564 is the same as that of the air guide duct 114 of the first embodiment. The bottom surface 606 and the upper surface 612 form a streamlined air passage. Therefore, the air guide duct 564 of this embodiment can also minimize the energy loss of the air flow discharged from the centrifugal fan 562, and change the direction of the air flow by 90 degrees to guide the inside of the duct 130. As a result, the maximum wind force and maximum static pressure of the centrifugal fan 562 can be effectively utilized to transport the air containing the fragrance to a distant place, and the fragrance floating around can be dissipated.

[0107] However, on the other hand, the shapes of the air guide duct 564 and the air guide duct 114 are quite different.

[0108] For example, when a Sirocco fan is used as an axial flow fan, its discharge port is rectangular. The long side of the rectangle is roughly the same as the length direction of the impeller blade. The short side of the rectangle is roughly the same as the width direction of the impeller. Generally speaking, the signal of the impeller in the length direction is larger than the width direction.

[0109] In such Figure 2 When the centrifugal fan 112 is configured as in the centrifugal fan 112 of FIG. Figure 2The vertical direction of the air flow is consistent. That is, in the case of the first embodiment, the centrifugal fan 112 sends out: a flow of air that is longer in the vertical direction and shorter in the left-right direction. In order to guide the flow of air to the inside of the duct 130, it is necessary to change the direction of the air flow from the horizontal to the vertical. In addition, it is necessary to change the horizontal flow of air that is shorter in the left-right direction and longer in the vertical direction into a longitudinal flow of air that conforms to the internal shape of the duct 130. If the flow of air that is longer in the vertical direction is changed in this way, the flow of air will be turbulent anyway. And when the air is discharged from the duct 130, the turbulence of the air flow will still remain. Therefore, the air discharged from the duct 130 moves in a diffused manner.

[0110] On the other hand, in Fig.17 and Fig.18 When the centrifugal fan 562 is configured as shown, the length of the long side of the outlet of the centrifugal fan 562 is roughly consistent with the lateral width of the inside of the duct 566. Therefore, the air guide duct 564 only changes the direction of the flow of the air discharged laterally from the centrifugal fan 562 upward by 90 degrees, and there is no need to adjust the plane distribution of the flow of the air. In addition, as described above, the internal shape of the air guide duct 564 is smooth and there are no factors that hinder the flow of air. As a result, in the third embodiment, the turbulence of the flow of the air discharged from the duct 566 is very small, and the fragrance can reach far away.

[0111] However, in the third embodiment, since the air flow is less turbulent, the effect of diffusing the fragrance is weaker than in the first embodiment. Therefore, the configuration of the third embodiment is suitable for the purpose of making the fragrance accurately reach a substantially fixed position. On the other hand, in the configuration of the first embodiment, although it is difficult to send the fragrance to such a precise point, the fragrance can be sent to the position in a diffused manner, so there is the following effect: the influence of the user's position can be basically avoided, and the fragrance can be efficiently transmitted.

[0112] In the above-mentioned embodiments, the inner circumference of the enhancer 62 is formed into a hexagon. However, this is to form the inner circumference of the enhancer 62 to match the outer circumference of the fragrance display 60, and the inner circumference of the enhancer 62 is not limited to a hexagon. The same is true when the outer circumference of the enhancer 62 is a hexagon.

[0113] In addition, in each of the above-mentioned embodiments, the duct 130 is formed along only one side of the hexagon of the outer circumference of the enhancer 62. However, the present invention is not limited to such an embodiment. For example, the duct may be arranged along two or three sides of the hexagon. However, in order to miniaturize the enhancer, the upper limit is to arrange the duct along three sides of the hexagon. If the duct is arranged along more than three sides, the enhancer will be enlarged. There is also the following problem: since the cross-sectional area of ​​the duct increases, it is difficult to generate a sufficient maximum static pressure without increasing the size of the fan.

[0114] In addition, the duct may be provided so as to straddle a portion of each of two sides sandwiching the vertices of the hexagon of the outer circumference of the intensifier 62. Similarly, the duct may be provided so as to straddle a portion of each of one side and its left and right sides.

[0115] In addition, the periphery of the enhancer 62 is not limited to a hexagon. In the present embodiment, the periphery of the enhancer 62 is also a hexagon because the periphery of the fragrance display 60 is a hexagon. For example, if the periphery of the fragrance display 60 is an octagon, the periphery of the enhancer 62 is also an octagon naturally. Of course, the periphery of the fragrance display 60 can also be a polygon that is not a regular polygon, and can be other shapes such as a circle. In these cases, the periphery shape of the enhancer 62 is also naturally consistent with the periphery shape of the fragrance display 60. When the periphery of the enhancer is set to a circle, it is different from the case of a polygon, that is, the width of the pipeline of the enhancer cannot be determined according to the number of sides. In this case, for example, it is desired that the pipeline of the enhancer is set within the range of 1 / 10 to 1 / 3, preferably 1 / 8 to 1 / 4, and more preferably 1 / 7 to 1 / 5 of the periphery of the enhancer. The cross-sectional shape of the interior of the pipeline at this time may not be roughly trapezoidal as in the above-mentioned embodiment, for example, it may be that the pipeline is deformed in a manner to form a curve along the periphery of the enhancer.

[0116] The embodiments disclosed this time are merely examples, and the present invention is not limited to the above-described embodiments. The scope of the present invention includes all modifications within the meaning and scope equivalent to the expressions indicated by the claims with reference to the detailed description of the invention and described herein.
