Description

  The present invention relates to a fragrance generating apparatus capable of exchanging a fragrance and extending a period until replacement by taking out a fragrance component to the outside only when necessary.

  As a conventional fragrance device, there is an opener in the upper part of a container containing a fragrance, from which the fragrance component is volatilized to the outside, and a fan forcibly blown to the outside by a fan. In recent years, in signboards and vending machines, etc., devices that emit fragrances for the purpose of advertising effects and sales improvement effects have been studied. Or what is arrange | positioned in the back and the inside of a vending machine is proposed.

  However, in the conventional fragrance, since the fragrance component always flows out from the opening, the fragrance easily evaporates in a short time, and the odor gradually changes due to the difference in volatility of the components contained in the fragrance. There was a problem that. Furthermore, since the fragrance component is put out regardless of whether there is a person in front of the signboard or the vending machine, the fragrance is wasted.

  On the other hand, in the apparatuses described in Patent Document 1 and Non-Patent Document 1, the fragrance is held in the sealed space and the fragrance component is allowed to flow out only when necessary by the compressor. It is possible to lengthen the period until all the agent is volatilized, and to prevent the odor from changing over time.

However, the devices described in Patent Document 1 and Non-Patent Document 1 are configured to take in the aroma component volatilized in the air sent to the outside by bringing the air into contact with the air freshener filled in the space.
There are strong odors and light odors. In the case of strong odors, it can be perceived even when the intake (concentration) of aroma components in the air is low, but especially in the case of light odors. It is difficult to perceive the light odor unless the amount (concentration) of aroma components in the air is increased.

  In the apparatus described in Patent Document 1 and Non-Patent Document 1, since air is in direct contact with only the fragrance, it is necessary to expand the contact area in order to increase the intake amount (concentration) of the fragrance component in the air. In addition, since the fragrance is filled in the cylinder, it is necessary to increase the radial dimension of the cylinder in order to increase the contact area, resulting in an increase in the size of the apparatus. There is.

In addition, the apparatus described in Patent Document 1 requires a container filled with a fragrance to be integrally incorporated in a fixing housing, and a fixing housing needs to be created separately, resulting in an increase in cost. In addition, since the container and the fixing housing are fixed to the apparatus main body, it takes time for construction to fix the fixing casing to the apparatus main body, and it is necessary to refill the fragrance from the front surface of the object. there were. In addition, since the size of the fixing housing is the size including the cartridge, when attaching to a signboard, digital signage, etc., the presence of the device is ensured by installing the fixing housing in front of the object. At first glance, there was a problem of obstructing the design of objects (advertisements) such as signs and digital signage.
In addition, the replacement of the fragrance is performed every two weeks to one month depending on the volatilization degree of the fragrance. In the apparatuses described in Patent Document 1 and Non-Patent Document 1, It took time for the replacement, and there was a problem that the operating efficiency of the fragrance generator was poor.

  Therefore, the present invention can easily replace the cartridge containing the fragrance in the housing for fixing from the back of the object, and there is no device that can be seen from the appearance of the object. It is an object of the present invention to provide a fragrance generating apparatus in which a sufficient amount of air (gas) containing a fragrance component is discharged at a predetermined speed and at a desired timing.

  In order to solve the above-described problems, an aroma generating device of the present invention has a discharge port that opens to the outside, includes a fixing portion that is fixed to an object, and a channel that extends in a predetermined direction. A main body formed so that one end is connected to the discharge port, a compressor connected to the other end of the flow channel and sending gas in the flow channel to the discharge port side, and a fragrance from which a fragrance component is volatilized A cartridge that is housed and detachable from the main body, and a controller that drives the compressor based on a trigger signal from the outside, the cartridge having air permeability between the cartridge and the flow path And having a capturing part for taking in a fragrance component volatilized from the fragrance.

  In addition, the fragrance generating apparatus of the present invention is characterized in that it has at least two capturing portions that capture and capture the fragrance component volatilized from the fragrance into the gas sent by the compressor.

  Further, the fragrance generating device of the present invention has a valve portion that closes the discharge port by its own weight when the compressor is not driven and opens when the gas in the flow path is sent out by driving the compressor. To do.

  Further, the cartridge of the fragrance generating device of the present invention is detachably screwed to the main body.

  In addition, the cartridge of the fragrance generating device of the present invention is detachably attached to the fixed portion.

  According to the present invention, it is possible to easily replace the cartridge containing the fragrance from the inside of the object, and it is possible to lengthen the period until the replacement by taking out the fragrance component to the outside only when necessary. . Furthermore, since the fragrance is held in the sealed space and the fragrance component is allowed to flow out only when necessary by the compressor, the period until the fragrance is completely volatilized can be lengthened, It is possible to minimize the change in odor over time. In addition, it is possible to provide an aroma generating device in which a sufficient amount of gas containing an aroma component is discharged at a predetermined speed and at a desired timing.

<First Embodiment>
FIG. 1A is a plan view showing the configuration of the fragrance generating apparatus 10 according to the first embodiment, and FIG. 1B is a side view of the fragrance generating apparatus 10 viewed along the Y direction. 2A is a cross-sectional view taken along line BB ′ of FIG. 1A, FIG. 2B is an enlarged view of the 2B portion of FIG. 1A, and FIG. 2C is a cross-section of the fragrance generating apparatus according to the modification. It is a figure and is a figure corresponding to (B). FIG. 3 is a block diagram showing a control system of the fragrance generating apparatus 10.

  As shown in FIG. 1, the fragrance generating device 10 includes a cartridge 20, a main body 30 formed integrally with the fixing portion 40, and a compressor 50. Although the fragrance generating apparatus 10 of 1st Embodiment is shown as an aspect fixed to the back surface of objects, such as an electronic signboard and other signboards, and a vending machine, the fragrance generating apparatus of this invention is the inside of a target object, a side surface, Or it can also provide in the front.

  The cartridge 20 is a container in which the fragrance is stored in the storage space 21 and is made of, for example, synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, glass, and the like, and is perpendicular to the main body 30. It is arranged on the lower side (Z direction in FIG. 1). The entire upper surface of the cartridge 20 in the vertical direction is opened as an opening 22 as an outflow opening. The opening 22 has a circular shape when seen in a plan view along the Z direction. A thread groove 23 is formed on the outer peripheral surface of the wall portion 22a (FIG. 2A) forming the opening 22.

The fragrance H is accommodated in the cartridge 20 in a state where the liquid fragrance material from which the fragrance component is volatilized at room temperature is impregnated with beads, gel, or a retaining agent. The storage state of the fragrance H is not limited as long as it does not hinder the evaporation of the fragrance component. For example, it is made into a bead or gel by adding a gelling agent, and also silica gel, non-woven fabric, felt, paper, etc. Impregnated with a preservative.
In addition, the volatilization amount of the fragrance | flavor H can be controlled by using the fragrance material which volatilizes at higher temperature than normal temperature and heating the cartridge 20 at the time of use.

  A main body 30 is disposed on the upper side of the cartridge 20 so as to cover the opening 22 of the cartridge 20. The main body 30 is made of, for example, a synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, glass, or the like. The main body 30 includes a central portion 30a having a substantially rectangular shape in plan view, and connecting portions 35 and 36 extending outward from the approximate center positions of both side surfaces of the central portion 30a in the X direction along the X direction.

  In the main body 30, an internal space 31 through which gas can flow is formed adjacent to the flow path 34, and an opening 32 for ensuring air permeability between the internal space 31 and the flow path 34 is formed. Has been. The opening 32 is circular in plan view. A thread groove 33 is formed on the inner peripheral surface of the wall 32a (FIG. 2A) forming the opening 32. The opening 22 of the cartridge 20 and the opening 32 of the main body 30 have shapes corresponding to each other, and the screw groove 23 of the cartridge 20 and the screw groove 33 of the main body 30 are screwed to each other, whereby the cartridge 20 and the main body 30 are Is removably screwed.

  On the upper side of the internal space 31 of the main body 30, as shown in FIG. 1B, a flow path 34 that communicates with the internal space 31 and extends in a circular shape on the XY plane is formed. The internal space 31 and the flow path 34 are connected to each other via a ventilation opening 34 a (FIG. 2A) provided on the side surface of the flow path 34. The ventilation opening 34a has a circular shape whose diameter is smaller than that of the internal space 31 in plan view. The cartridge 20 has a capturing part T that takes in the fragrance component volatilized from the fragrance H with air permeability between the cartridge 20. Specifically, the flow path 34 and the internal space 31 are arranged in two upper and lower layers, and the flow path 34 and the internal space 31 having a two-layer structure are configured such that the fragrance component volatilized from the fragrance H is transferred to the flow path 34 and the internal space. A capturing portion T for capturing the gas sent into the gas 31 is configured.

  The flow path 34 further extends into the connecting portions 35 and 36 in the X direction. Of these connecting portions 35 and 36, the first connecting portion 35 on the object S side is formed integrally with a plate-like fixing portion 40 extending upward in the Z direction. Here, the target object S is a wall part which comprises a vending machine. This wall portion may be a wall portion constituting the back surface of the vending machine or a wall portion provided inside.

  As shown in FIG. 2B, a discharge port 35 a is provided on the surface of the first connecting portion 35 on the object S side, and is connected to a hole S <b> 2 provided in the object S. The inner diameter R1 (FIG. 2B) of the discharge port 35a is smaller than the inner diameter R2 (FIG. 2A) of the flow path 34 in the range corresponding to the ventilation opening 34a, and is within the second connecting portion 36. It is smaller than the inner diameter R3 (FIG. 2A) of the inflow port 36a. The hole S2 can be provided at an arbitrary position of the object S. For example, the hole S2 may be provided in the vicinity of the product outlet of the vending machine.

  One end of the pipe part 51 is connected to the inlet 36 a of the second connecting part 36. The other end of the pipe portion 51 is connected to the compressor 50. Thereby, the internal flow path 52 of the pipe part 51, the inflow port 36a in the 2nd connection part 36, and the flow path 34 are mutually connected. Furthermore, the flow path 34 is connected to the external space through the connecting portion 35 and connected to the hole S2 of the object S via the discharge port 35a.

  In this way, the internal space from the compressor 50 to the pipe 51, the inlet 36a in the second connecting portion 36, the flow path 34, the discharge port 35a of the first connecting portion 35, and the hole S2 is connected. A distribution path is configured, and this distribution path is filled with gas. When the compressor 50 is driven, a predetermined pressure is applied to the gas in the flow path, so that a gas flow discharged from the hole S2 to the outside is generated.

  Here, the flow path 34 is connected to the accommodation space 21 of the cartridge 20 via the internal space 31 and the opening 32 of the main body 30. For this reason, the fragrance component is volatilized from the fragrance H stored in the storage space 21 at room temperature, and this fragrance component enters the internal space 31 of the main body 30 from the opening 22 of the cartridge 20 and further flows into the flow path 34. And is trapped by the gas in the flow path 34 and the internal space 31 of the capturing portion T. Therefore, since the flow path 34 and the internal space 31 of the trap part T are arranged in two upper and lower layers, the fragrance component volatilized from the fragrance H is trapped by the gas in the trap part T having an upper and lower two-layer structure. As a result, the intake amount (concentration) of the fragrance component taken into the gas in the trapping part T increases. Thereby, even in the case of a light odor, the odor can be surely sensed. When the compressor 50 is driven in this state, a gas flow toward the discharge port 35a is generated in the flow path including the flow path 34, so that the fragrance component taken into the gas by the trapping portion T having a two-layer structure is also discharged from the discharge port. It flows to the side of 35a and flows out to the outside.

  Here, since the inner diameter R1 of the discharge port 35a is smaller than the inner diameter R2 of the flow path 34 in a range corresponding to the ventilation opening 34a and smaller than the inner diameter R3 of the inflow port 36a, The inflowing gas is throttled by the small diameter of the discharge port 35a, and the flow rate at the time of discharge of the discharge port 35a is accelerated from the inflow port 36a and discharged to the outside. In this way, the gas containing the fragrance component is accelerated and discharged, so that it is possible to emit the scent to a distant place in accordance with any timing.

  In the present embodiment, an example in which the diameters of the inner diameters R1, R2, and R3 are different from each other has been described. However, the inner diameters R1, R2, and R3 may be configured to have the same diameter.

  As shown in FIG. 1A, two screw holes 41 and 42 penetrating along the X direction are provided in the upper portion of the fixed portion 40. By screwing screws (screws) 41a and 42a passed through the screw holes 41 and 42 into the object S, the fixing part 40 and the main body part 30 integrated with the fixing part 40 are the object. It is fixed to the back surface S1 of S.

  Next, the operation principle of this embodiment will be described. As shown in FIG. 3, first, a trigger signal is generated and output to the control unit 61. The trigger signal is a signal given from a vending machine as the object S. For example, when a user of the vending machine presses a button corresponding to a product to be purchased, the trigger signal is linked. To the control unit 61.

  Next, the control unit 61 outputs an instruction signal to the drive circuit 62. Then, the drive circuit 62 outputs a drive signal to the compressor 50. This drive signal is a signal generated according to an instruction signal from the control unit 61 that has received the trigger signal, and is, for example, a rectangular wave signal indicating on / off.

  The compressor 50 is driven by receiving the drive signal, receives the drive signal, and sends compressed air (gas) to the flow path 34.

  As described above, when the user of the vending machine operates the button corresponding to the product, the compressor 50 is driven at a predetermined timing, and the gas output from the compressor 50 is, as described above, the pipe portion 51 and the inlet 36a. The fragrance component flows into the flow path 34 and is mixed with the fragrance component in the flow path 34 and the accommodating space 21, and the gas containing the fragrance component is accelerated from the discharge port 35 a of the first connection portion 35, so that the hole S 2 of the object S is obtained. A gas containing a fragrance component is discharged from. As the predetermined timing, for example, it can be set to a timing at which the product is expected to fall to the outlet after the user operates the button. When this timing is reached, when the user approaches the outlet to take the product The gas containing the fragrance component is discharged from the hole S2.

Hereinafter, modified examples of the first embodiment will be described.
In the first embodiment, when the compressor 50 is driven, the gas in the flow path 34 is pressurized, and thereby the gas containing the fragrance component is discharged to the outside, but the period when the compressor 50 is not driven. Since it is not pressurized, the outflow of the fragrance component can be suppressed. However, since the hole S2 is always open, there is a possibility that the gas in the flow path 34 will gradually flow out to the outside. On the other hand, as shown in FIG. 2C, when the valve portion 70 is provided in the discharge port 35a, the discharge performance when the compressor 50 is driven is maintained, and the outflow of gas to the outside when the compressor 50 is not driven is further improved. It becomes possible to suppress it reliably. The valve portion 70 is made of a lightweight, plate-like or film-like material, for example, a synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, and rotates around a rotation shaft 71 fixed to the fixing portion 40. To do. When the compressor 50 is not driven, the valve portion 70 is in a posture along the Z direction due to its own weight, and closes the discharge port 35a. When the gas in the flow path 34 is compressed by driving the compressor 50, the valve portion 70 is in the XY plane. It moves so that it may follow, and the discharge outlet 35a is open | released.

  Further, a human sensor, for example, an infrared sensor may be disposed on the surface of the object S and the compressor 50 may be driven using the detection output as a trigger signal. In this case, in order to drive the compressor 50 appropriately, it is preferable to set the trigger signal to be output when the human sensor keeps outputting the detection output for a predetermined time.

Since it comprised as mentioned above, according to the fragrance generator 10 which concerns on 1st Embodiment, there exists the following effect.
(1) By screwing the screw groove 23 of the cartridge 20 and the screw groove 33 of the main body 30 to each other, the cartridge 20 can be easily detached from the main body 30.

  (2) Since the gas containing the fragrance component is discharged by driving the compressor 50 only when necessary, the fragrance can be volatilized in a short period of time, or the change in odor over time can be minimized, and the cartridge can be replaced. The period up to can be lengthened.

  (3) Since the fragrance component that flows out from the opening 22 of the cartridge 20 flows into the flow path 34 in the main body 30 independent of the cartridge 20, the gas in the flow path 34 is efficiently supplied by the compressor 50. Therefore, a sufficient amount of gas containing a fragrance component is discharged at a predetermined speed and at a desired timing.

Second Embodiment
Next, a second embodiment of the present invention will be described.
FIG. 4 is a side view showing the configuration of the fragrance generator 110 according to the second embodiment. FIG. 5 is an exploded side view of the fragrance generator 110. 6A is a cross-sectional view taken along line 6A-6A ′ of FIG. 5, FIG. 6B is a side view of the cartridge 120, FIG. 6C is an enlarged view of a portion 6C of FIG. 5, and FIG. 5 is an enlarged view of a 6D portion of 5. FIG. FIG. 6E is a cross-sectional view of the fragrance generating apparatus according to the modification, and corresponds to FIG.
Since the control system of the fragrance generating apparatus of the second embodiment is the same as the control system corresponding to FIG. 3, the detailed description thereof is omitted.

  As shown in FIG. 4, the fragrance generating device 110 includes a cartridge 120, a main body 130, a fixing unit 140, and a compressor 150. The fragrance generating device 110 of the second embodiment is shown as an aspect that is fixed to the back surface of an object such as an electronic signboard or other signboard or a vending machine, like the fragrance generating device 10 of the first embodiment.

  The cartridge 120 is a hollow cylindrical container, and is made of, for example, molded synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, glass, or the like. The cartridge 120 is disposed such that the central axis 120x is along the X axis. In the cartridge 120, an insertion space 123 into which the cylindrical portion 131 of the main body 130 is inserted is formed as a space including the central axis 120x. The insertion space 123 penetrates the cartridge 120 along the central axis 120x.

  A storage space 121 for storing the fragrance H is formed outside the insertion space 123 along the central axis 120x. In the cylindrical wall portion 124 that separates the insertion space 123 and the accommodation space 121, a large number of minute ventilation openings 132 are formed as outflow openings. The ventilation opening 132 is formed to have a smaller diameter than the bead-shaped fragrance H accommodated in the accommodation space 121.

  Further, in the X direction, a first connection space 125 and a second connection space 126 are formed inside the cartridge 120 and outside both the accommodation spaces 121, respectively. The storage space 121 and the first connection space 125 are partitioned by a first wall 121a that extends in the YZ plane, and the storage space 121 and the second connection space 126 are a second wall provided in parallel with the first wall 121a. It is partitioned off by the part 121b. By these wall parts 121a and 121b, both sides in the X direction of the accommodation space 121 are closed, so that the fragrance H does not leak outside.

  The fragrance H is accommodated in the cartridge 120 in a beaded or impregnated state with a liquid fragrance material from which the fragrance component evaporates at room temperature. The storage state of the fragrance does not penetrate into the insertion space 123 and the form thereof is not limited as long as it does not prevent the evaporation of the fragrance component. For example, it is made into a bead or gel by adding a gelling agent, Further, it may be impregnated with a retaining agent such as silica gel, non-woven fabric, felt or paper material.

  The main body 130 includes a cylindrical portion 131 that extends along the X direction, and a flow path 134 that penetrates the cylindrical portion 131 in the longitudinal direction is formed therein. Both ends of the cylindrical portion 131 in the longitudinal direction are respectively a first connecting portion 135 and a second connecting portion 136, and one first connecting portion 135 is inserted and coupled into the fixing portion 140 and the other second connecting portion. The portion 136 is inserted and coupled into the tube portion 151. The cylindrical portion 131 is made of, for example, a synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, glass, or the like. A large number of ventilation openings 132 (FIG. 6C) through which gas can enter and exit are formed in the cylindrical portion 131 constituting the side wall of the flow path 134. The vent opening 132 is formed with a smaller diameter than the fragrance H so that the bead-shaped fragrance H accommodated in the accommodation space 121 does not enter the flow path 134.

  In the second embodiment, when the gas is sent into the flow path 134 by the compressor 150, a part of the gas passes between the accommodation space 121 and the wall portion 124 from the ventilation opening 132 on the upstream side of the flow path 134. The remaining gas flows into the wall 124. Since the fragrance H is stored between the storage space 121 and the wall 124, the fragrance component volatilized from the fragrance H stays between the storage space 121 and the wall 124 and passes through the ventilation opening 132. In order to leach into the wall portion 124, the gas is taken into the gas between the accommodation space 121 and the wall portion 124 and the gas in the wall portion 124.

  The cartridge 120 has a trapping portion T that takes air and has an air permeability and takes in the fragrance component volatilized from the fragrance H. In the second embodiment, the trapping portion T that traps the fragrance component in the gas is formed between the accommodation space 121 and the wall portion 124 and in the wall portion 124. Therefore, in the second embodiment, since the two capturing portions T are formed in the cartridge 20, the intake amount (concentration) of the aroma component taken into the gas sent by the compressor 150 is increased. The same effects as those of the first embodiment described above can be obtained.

  A coupling portion 137 for coupling the main body portion 130 and the cartridge 120 to each other on the outer side in the radial direction of the cylindrical portion 131 on the second connecting portion 136 side of the main body portion 130, that is, the side where the tube portion 151 is coupled. Is provided. Here, the second connecting portion 136 extends from the coupling portion 137 to the tube portion 151 side.

  The coupling portion 137 is formed of an elastically deformable material, for example, rubber, and includes a press-fit coupling portion 138 and a disc-shaped regulation plate portion 139 disposed outside the press-fit coupling portion 138 in the X direction.

  The press-fit coupling portion 138 has a diameter larger than the diameter of the first connection space 125 in a natural state, and the first connection space 125 of the cartridge 120 is contracted in a state where the outer diameter is contracted to a small size by applying an external force to be elastically deformed. It is pushed in to insert and remove. Thus, the press-fit coupling part 138 press-fitted into the first connection space 125 expands so as to push the inner wall of the first connection space 125 outward due to its elasticity, and thereby the connection part 137 enters the first connection space 125. Fixed.

  The restriction plate portion 139 has a disk shape having an outer diameter larger than the outer diameter of the cartridge 120, and one end face in the longitudinal direction of the cartridge 120 when the press-fitting coupling portion 138 is inserted into the first connection space 125. The position of the coupling portion 137 with respect to the cartridge 120 is determined by abutting against the cartridge 120a.

  As described above, when the press-fitting coupling portion 138 is press-fitted into the first connection space 125, the cylindrical portion 131 is inserted into the insertion space 123 of the cartridge 120. As a result, the flow path 134 is surrounded from the outside by the storage space 121 of the cartridge 120, and the fragrance component volatilized from the fragrance H stored in the storage space 121 is formed in the wall 124, and It flows into the flow path 134 through the vent opening 132 formed in the tubular portion 131.

  On the other hand, the press-fit coupling portion 144 of the fixing portion 140 is pushed into the second connection space 126 of the cartridge 120 so as to be insertable / removable. The fixing portion 140 includes a fixing plate portion 143 that is fixed to the back surface S1 of the object S, and a press-fit coupling portion 144 that extends from the fixing plate portion 143 to the cartridge 120 side.

  The press-fit connecting portion 144 has a diameter larger than the diameter of the second connection space 126 in the natural state, like the press-fit connecting portion 138 of the connecting portion 137, and shrinks the outer diameter to a small extent by elastically deforming by applying an external force. In this state, the cartridge 120 is pushed into the second connection space 126 of the cartridge 120 so that it can be inserted and removed. Thus, the press-fit coupling portion 144 press-fitted into the second connection space 126 expands so as to push the inner wall of the second connection space 126 outward due to its elasticity, and thereby the press-fit connection portion 144 is inside the second connection space 126. Fixed to.

  Here, the cartridge 120 can be detached from the fixed portion 140 by moving in the X direction. Further, the press-fit coupling portion 138 is taken out from the first connection space 125 and the cylindrical portion is taken from the insertion space 123. 131 can be pulled out, and by these, the cartridge 120 can be detached from the main body 130. That is, the cartridge 120 is detachable from the main body 130.

  The fixed plate portion 143 has a disk shape having an outer diameter larger than the outer diameter of the cartridge 120, and one end surface in the longitudinal direction of the cartridge 120 when the press-fit coupling portion 144 is inserted into the second connection space 126. The position of the fixing part 140 with respect to the cartridge 120 is determined by abutting on the cartridge 120b. At this time, the first connecting portion 135 of the cylindrical portion 131 of the main body portion 130 inserted into the insertion space 123 of the cartridge 120 is inserted into the connecting hole 145 provided in the fixing portion 140, and the position in the YZ plane is set. It is decided. As shown in FIGS. 5 and 6D, the connection hole 145 is connected to the discharge port 146 that penetrates the fixed plate portion 143 in the thickness direction (X direction). The discharge port 146 is formed such that the area on the YZ plane increases as the distance from the connection hole 145 increases in the X direction.

  As shown in FIG. 5, two screw holes 141 and 142 penetrating along the X direction are provided in the peripheral portion of the fixed portion 140 having a circular shape in plan view. By screwing screws (screws) 141a and 142a passed through the screw holes 141 and 142 into the object S, the fixing part 140 and the main body part 130 coupled to the fixing part 140 are connected to the object S. It is fixed to the back surface S1.

  As shown in FIG. 6D, the flow path 134 is connected to the hole S <b> 2 provided in the object S through the discharge port 146. Of the discharge port 146, the inner diameter R11 (FIG. 6D) of the end portion 146a connected to the flow path 134 is smaller than the inner diameter R12 of the flow path 134 (FIG. 6C).

  One end of the pipe portion 151 is connected to the inlet 136a of the second connecting portion 136. The other end of the pipe portion 151 is connected to the compressor 150. Thereby, the internal flow path 152 of the pipe part 151, the inflow port 136a in the 2nd connection part 136, and the flow path 134 are mutually connected. Furthermore, the flow path 134 is connected to the external space through the first connection part 135, connected to the hole part S <b> 2 of the object S via the discharge port 146.

  In this manner, the internal space from the compressor 150 through the pipe 151, the inlet 136a of the second connecting portion 136, the flow path 134, and the first connecting portion 135 to the discharge port 146 and the hole S2 is connected. A distribution path is configured, and this distribution path is filled with gas. When the compressor 150 is driven, a predetermined pressure is applied to the gas in the flow path, so that a gas flow discharged from the hole S2 to the outside is generated.

  Here, the flow path 134 is connected to the accommodation space 121 of the cartridge 120 through the ventilation opening 132 of the cylindrical portion 131 and the opening of the wall portion 124 of the cartridge 120. Therefore, at normal temperature, the fragrance component is volatilized from the fragrance H stored in the storage space 121, and this fragrance component enters the insertion space 123 from the wall portion 124 of the cartridge 120 and further passes through the ventilation opening 132. It reaches the flow path 134 and is mixed with the gas in the flow path 134. When the compressor 150 is driven in this state, a gas flow toward the discharge port 146 is generated in the flow path including the flow path 134. Therefore, the fragrance component that has flowed out from the housing space 121 to the flow path 134 is also on the discharge port 146 side. Flows out to the outside.

  Here, since the inner diameter R11 of the end 146a of the discharge port 146 is smaller than the inner diameter R12 of the flow path 134, the gas flowing in from the inflow port 136a is throttled with a smaller diameter than the discharge port 146, and is smaller than the inflow port 136a. The gas containing the fragrance component is accelerated by the flow rate at the time of discharge from the discharge port 146 and discharged to the outside.

  In addition, when the compressor 150 is driven, part of the gas flows into the gap between the fragrance H from the ventilation opening 132 of the flow path 134. A gas containing not only a gas but also an inert gas or the like is used in the gap of the fragrance H. The inflowing gas is mixed with the fragrance component volatilized between the fragrances H, returns to the flow path 134 again, and is discharged from the discharge port 146.

  In this way, the gas containing the fragrance component is accelerated and discharged, so that it is possible to emit the scent to a distant place in accordance with any timing.

  Also in the fragrance generating device 110 of the second embodiment, it is preferable to provide the valve portion 170 as in the first embodiment. As shown in FIG. 6E, when the valve portion 170 is provided at the discharge port 146, the discharge performance when the compressor 150 is driven can be maintained, and the outflow of gas to the outside when not driven can be more reliably suppressed. It becomes possible. The valve portion 170 is made of a lightweight, plate-like or film-like material, for example, a synthetic resin such as polypropylene, polyethylene terephthalate, or polyvinyl chloride, and rotates around a rotation shaft 171 fixed to the fixed plate portion 143. Move. When the compressor 150 is not driven, the valve portion 170 takes a posture along the Z direction due to its own weight, and closes the discharge port 146. The discharge port 146 is opened so as to be movable.

The aroma generator 110 according to the second embodiment has the following effects.
(1) Since the cylindrical portion 131 is inserted into the cartridge 120 and further coupled to the fixing portion 140 so as to be insertable / removable, the cartridge 120 and the main body 130 are coupled to each other, so that the cartridge 120 can be easily replaced. .

(2) Since the fragrance component flowing out from the opening provided in the wall portion 124 of the cartridge 120 flows into the flow channel 134 in the cylindrical portion 131 independent of the cartridge 120, the gas in the flow channel 134 Is efficiently pressurized by the compressor 150, a sufficient amount of gas containing a fragrance component is discharged at a predetermined speed and at a desired timing.
Other operations, effects, and modifications are the same as those in the first embodiment.

  As described above, the fragrance generating apparatus according to the present invention can lengthen the period until the fragrance is completely volatilized, and can minimize the change in odor over time, Furthermore, it is useful in that a sufficient amount of gas containing an aroma component can be discharged at a predetermined speed and at a desired timing.

  The present invention can be embodied in many forms without departing from its essential characteristics. Therefore, it is needless to say that the above-described embodiment is exclusively for description and does not limit the present invention.
