Description

Oil container and fragrance diffuser

The present invention relates to an oil container and an aroma diffuser.

In recent years, the fragrance of essential oils has been drifted, for example, in business spaces in beauty salons, hotels, clinics, and living spaces in ordinary households.

Generally, a relatively large fragrance diffuser suitable for business use is used in order to allow fragrance to float in a wide business space. On the other hand, in order to float a fragrance in a narrow living space, a relatively small fragrance diffuser is used. Moreover, the living space in a general household is narrower than the business space. Therefore, an oil pod may be used to vaporize the essential oil dropped into the pod or its diluted oil (hereinafter sometimes simply referred to as “essential oil”) and release it into the living space.

Many of the fragrance diffusers used for business use diffuse essential fragrance by making essential oil fine particles with compressed air from a compressor and spraying it in a mist form from a nozzle. In addition, many fragrance diffusers used in general households diffuse essential fragrance by emulsifying essential oil and water by ultrasonic waves and spraying them in the form of a mist.

In addition, in patent document 1 preceding this application, in order to diffuse essential oil in a wide space, aroma water formed by mixing water pressurized with a high-pressure pump and essential oil is emulsified and sprayed in a mist form from a mist nozzle. An aroma mist spray system is disclosed.

JP 2009-233530 A

However, the conventional technology has room for improvement in the following points. That is, since the conventional fragrance diffuser requires a compressor and a pump, the structure tends to be complicated. Further, when the essential oil is sprayed with compressed air, the nozzle may be clogged, and maintenance must be performed frequently. On the other hand, when the essential oil is vaporized using the oil pod, the essential oil must be replenished frequently, which is inconvenient. In addition, vaporization is insufficient, and it is difficult to sufficiently diffuse the fragrance in a wide space.

The present invention has been made in view of the above-mentioned background, and is an oil container that can easily evaporate essential oil and the like continuously, and can easily float a fragrance in the space with a relatively simple structure, which is easy to use. It is intended to provide an aroma diffuser.

One aspect of the present invention is formed in a bottomed cylindrical shape having an opening on the upper side, and a container body for storing essential oil or diluted oil therein,
A core material for sucking up the essential oil or its diluted oil from the container body;
An absorber that is formed in a planar shape and absorbs the essential oil or its diluted oil sucked up from the core material;
It is attached to the opening of the container body, and has a lid for holding the core and the absorber,
The absorber has an outer shape larger than the cylindrical diameter of the container body,
The lid includes a lid main body that holds the core material, and the absorbent body protrudes outward from the outer peripheral surface of the container main body, and the absorbent body is exposed to the outside. And an oil container having a holding portion for holding.

Another aspect of the present invention is a mounting portion for mounting an oil container capable of sucking out essential oil or its diluted oil contained in the container to the outside of the container, and a plurality of holes formed around the mounting portion. A first space portion including a placement surface portion having a portion;
A second space portion disposed below the first space portion, having a bottom surface portion formed with an outside air suction port, and communicating with the first space portion via the hole;
It is arranged in the second space and is configured to be switched to an on state or an off state by a power switch, and air sucked from the outside air suction port when the power switch is turned on is A blower fan that blows air into the first space through the hole;
The fragrance diffuser is formed above the first space and has a discharge port that communicates the first space with the outside.

The oil container has the above configuration. Therefore, when the essential oil or its diluted oil is put into the container body, the essential oil or the like is sucked up by the core material. The sucked essential oil or the like is absorbed by the absorber from the core material and spreads in the surface direction of the absorber. Here, since the outer shape of the absorber is formed larger than the cylindrical diameter of the container main body, the absorber is held by the holding portion of the lid in a state of protruding outward from the outer peripheral surface of the container main body. The absorber is held by the holding part of the lid part with the surface exposed to the outside.

Therefore, when there is a wind that flows upward from the bottom of the oil container, the wind hits the portion of the absorber that protrudes outward from the outer peripheral surface of the container body, and the essential oil absorbed by the absorber Vaporization is encouraged. When the essential oil or the like absorbed by the absorber due to vaporization decreases, the essential oil or the like is continuously supplied from the core material to the absorber.

Therefore, the above oil container is easy to vaporize essential oil continuously.

The fragrance diffuser has the above configuration. For this reason, when the oil container described above is placed on the placement portion of the first space portion and the power switch is turned on, the blower fan operates, and external air is sucked into the second space portion from the outside air suction port. Is done. The air sucked into the second space is blown into the first space through the hole. The wind that has flowed into the first space portion flows from the lower side to the upper side of the oil container along the outer peripheral surface of the oil container. At this time, wind hits a portion of the absorbent body that protrudes outward from the outer peripheral surface of the container body, and vaporization of the essential oil or the like absorbed by the absorbent body is promoted. When the essential oil or the like absorbed by the absorber due to vaporization decreases, the essential oil or the like is continuously supplied from the core material to the absorber. The air containing the vaporized essential oil or the like is discharged to an external space from a discharge port located above the first space portion. According to the fragrance diffuser, the essential oil and the like are sufficiently vaporized, so that the fragrance can be diffused in a wide space.

The above-mentioned fragrance diffuser has a relatively simple structure because it does not require a compressor or a pump for diffusing the fragrance by essential oil or the like. Moreover, since the said fragrance diffuser does not use a nozzle, it is not necessary to perform maintenance of the nozzle. Furthermore, as long as there is an essential oil or the like in the oil container, the essential oil or the like can be continuously vaporized, and it is not necessary to replenish the essential oil as often as an oil pod. Therefore, the fragrance diffuser is easy to use.

Therefore, the above fragrance diffuser can float fragrance in the space with a relatively simple structure and is easy to use.

In FIG. 1, it is a III-III arrow line view in the state where the absorber was removed. FIG. 4 is a sectional view taken along line IV-IV in FIG. 2. It is an external appearance perspective view of the fragrance diffuser of Example 2. It is the external appearance perspective view which looked at the fragrance diffuser of Example 2 from another angle. In the fragrance diffuser of Example 2, it is an external appearance perspective view in the state where the outer cover was removed. FIG. 6 is an explanatory view schematically showing a section VIII-VIII in FIG. 5 in a state where the oil container of Example 1 is placed. It is explanatory drawing which showed the upper opening-and-closing shutter in the fragrance diffuser of Example 2. FIG. It is explanatory drawing which showed the downward opening-and-closing shutter in the fragrance diffuser of Example 2. FIG.

In the oil container, the holding portion includes a plurality of claw portions that protrude outward from the outer peripheral edge of the lid main body and support the absorber from below, and a pressing portion that presses and fixes the absorber from above. can do.

In this case, the holding portion can reliably hold the absorber in a state where the absorber protrudes outward from the outer peripheral surface of the container body and the surface is exposed to the outside. Moreover, the adhesiveness of an absorber and a core material improves with the pressing force by a pressing part. Therefore, the essential oil or the like sucked up from the core material is easily transferred to the absorber, which is advantageous for promoting the vaporization of the essential oil or the like absorbed by the absorber.

In the oil container, the lid portion extends from the lid body toward the inside of the container body, the cylinder body into which the core material is inserted, the outer periphery of the cylinder body is provided to be movable in the cylinder axis direction, And a float part capable of floating on the essential oil or its diluted oil.

In this case, the float moves in the cylinder axis direction according to the level of the essential oil in the oil container. For this reason, a sensor switch that is actuated by the magnetic field of the magnet in the float portion is provided in the mounting portion of the oil container, thereby constituting a remaining amount sensor that notifies that the replenishment time of the essential oil in the oil container or its diluted solution has arrived. It becomes possible.

The fragrance diffuser is provided at the discharge port, and is configured to be able to open and close the discharge port in an open state in which the first space portion and the outside communicate with each other and a closed state in which the first space portion and the outside do not communicate with each other. The upper opening / closing shutter can be used.

In this case, by closing the upper opening / closing shutter, it is possible to suppress the discharge of vaporized essential oil or the like from unnecessary discharge ports. Therefore, in this case, it becomes easy to suppress consumption of essential oils and the like.

The fragrance diffuser is provided at the outside air suction port, and opens and closes the outside air suction port in an open state in which the second space portion and the outside communicate with each other and a closed state in which the second space portion and the outside do not communicate with each other. It can be set as the structure which has the downward opening-and-closing shutter comprised.

In this case, by closing the lower opening / closing shutter, it is possible to suppress unnecessary discharge of the evaporated essential oil or the like from the unnecessary air suction port. Therefore, in this case, it becomes easy to suppress consumption of essential oils and the like.

In the fragrance diffuser, the upper open / close shutter and the lower open / close shutter may be configured to be manually opened or closed, or may be automatically opened or closed. It may be configured. In the case of the former, the structure of the fragrance diffuser can be simplified because parts and the like for automation are not required. It is also advantageous for reducing the cost of the fragrance diffuser. In the latter case, since it is automatically opened and closed, the usability of the fragrance diffuser can be further improved.

Specifically, when the power switch is turned on, the fragrance diffuser is such that both the upper open / close shutter and the lower open / close shutter are opened, and when the power switch is turned off, the upper open / close shutter is opened. Further, the lower opening / closing shutter can be configured to be in a closed state.

In this case, at the start of use of the fragrance diffuser, both the upper opening / closing shutter and the lower opening / closing shutter are automatically opened. Therefore, in this case, air for promoting vaporization of essential oil or the like can be quickly sucked from the outside air suction port. Moreover, the air containing vaporized essential oil etc. can be rapidly discharged | emitted from a discharge port. Therefore, the fragrance can be floated in the space relatively quickly after the fragrance diffuser is activated. On the other hand, at the end of use of the fragrance diffuser, both the upper opening / closing shutter and the lower opening / closing shutter are automatically closed. Therefore, in this case, it is easy to suppress the occurrence of unnecessary vaporization of essential oil or the like. Therefore, in this case, the usability of the fragrance diffuser can be further improved.

In the above case, the configuration for opening and closing the upper opening / closing shutter and the lower opening / closing shutter is not particularly limited. The upper opening / closing shutter and the lower opening / closing shutter can be configured to be opened and closed using a small motor, for example. In this case, the discharge port and the outside air suction port can be opened and closed with high accuracy. Therefore, in this case, it becomes easy to suppress the vaporized essential oil or the like from unnecessarily flowing out from a slight gap between the discharge port and the outside air suction port.

The upper opening / closing shutter and the lower opening / closing shutter can also be configured to be openable / closable as follows, for example. In other words, the upper opening / closing shutter and the lower opening / closing shutter are fixed so as to be rotatable about respective middle portions as fulcrums. Permanent magnets (or electromagnets) are respectively disposed at the base end portions of the upper opening / closing shutter and the lower opening / closing shutter. An electromagnet (or permanent magnet) is arranged around the permanent magnet (or electromagnet). The upper opening / closing shutter and the lower opening / closing shutter can be opened and closed by rotating the upper opening / closing shutter and the lower opening / closing shutter around the fulcrum using the repulsive force between the energized electromagnet and the permanent magnet. You can also. Moreover, the structure by the motor mentioned above and the structure by a magnet can also be combined.

The fragrance diffuser has a diffuser main part on the side where the oil container is placed and an outer cover that covers the outer periphery of the diffuser main part, and the diffuser body is covered by the outer cover. One space portion can be formed.

In this case, since the diffuser body and the outer cover are separated, the degree of freedom in selecting the design of the outer cover is improved, and it becomes easy to obtain an aromatic diffuser with excellent design.

In the fragrance diffuser, when the oil container having the above-described float portion is used, the fragrance diffuser includes a sensor switch that is operated by a magnetic field of a magnet in the float portion, and when the sensor switch is turned on, It may be configured to have a remaining amount sensor that notifies that the replenishment time of the essential oil in the oil container has come.

In this case, the following effects can be obtained. That is, as the vaporization of the essential oil or the like absorbed by the absorbent body proceeds, the essential oil or the like stored in the oil container decreases, and the liquid level of the essential oil or the like decreases. And if a magnet and a sensor switch approach to the distance which the sensor switch provided in the mounting part can act | operate with the magnetic field of the magnet in a float part, a sensor switch will be in an ON state. When the sensor switch is turned on, the remaining amount sensor informs that it is time to replenish essential oil in the oil container. Therefore, in this case, it is possible to accurately know the replenishment time of the essential oil in the oil container, and the usability of the fragrance diffuser can be further improved.

The fragrance diffuser can be configured to have the oil container described above.

In addition, each structure mentioned above can be arbitrarily combined as needed, in order to obtain each effect mentioned above.

Hereinafter, the oil container and the fragrance diffuser of the example will be described with reference to the drawings. In addition, about the same member, it demonstrates using the same code | symbol.

Example 1
The oil container of Example 1 will be described with reference to FIGS. As shown in FIGS. 1 to 4, the oil container 1 of the present example includes a container body 10, a core material 11, an absorber 12, and a lid portion 13. This will be described in detail below.

The container body 10 is formed in a bottomed cylindrical shape having an opening 101 on the upper side. The container body 10 is for storing the essential oil or its diluted oil 102 therein. In this example, specifically, the container main body 10 is made of glass, and is used for storing natural essential oil as the essential oil or its diluted oil 102.

The core material 11 is for sucking up the essential oil 102 from the inside of the container body 1. In this example, specifically, the core material 11 is formed in a substantially strip shape from a non-woven fabric, and the essential oil 102 can be sucked up by a capillary phenomenon. In this example, specifically, the core member 11 is formed with a wide upper end, and a pair of both ends of the wide upper end are narrowed downward. A tapered portion 111 is formed. The core material 11 is held by the lid body 131 without dropping into the container body 10 by the taper portion 111 being locked to a lid body 131 (described later) of the lid portion 13.

The absorber 12 is formed in a planar shape. Further, the outer shape of the absorbent body 12 is larger than the cylindrical diameter of the container body 10. The absorber 12 is configured to be able to absorb the essential oil 102 sucked up from the core material 11. In this example, specifically, the absorber 12 is formed in a disk shape having a larger outer diameter than the cylindrical diameter of the container body 10 by a nonwoven fabric. The cylinder diameter of the container body 10 is about 55 mm, and the outer diameter of the absorber 12 is about 75 mm.

In this example, an example in which both the core material 11 and the absorbent body 12 are made of the same nonwoven fabric is shown. The core material 11 and the absorber 12 are not limited to the above, and may be made of different materials. Moreover, in this example, the example in which the core material 11 and the absorber 12 are comprised as a different body is shown. The core material 11 and the absorbent body 12 are not limited to the above, and may be configured by integrating both.

The lid 13 is attached to the opening 101 of the container body 10 and holds the core material 11 and the absorber 12. In this example, the lid portion 13 is detachably attached by being screwed to the container body 10. The lid 13 is made of a plastic material.

The lid portion 13 includes a lid body 131 and a holding portion 132. A lid body 131 in the lid portion 13 holds the core material 11.

More specifically, in this example, an insertion hole 131 a for inserting the core material 11 is formed in the central portion of the lid main body 131. A pair of corresponding tapered portions 131b are formed on the inner wall surface of the insertion hole 131a so as to correspond to the pair of tapered portions 111 of the core member 11 so that the hole diameter decreases downward. The core material 11 inserted from the lower end portion into the insertion hole 131a of the lid body 131 is in a state in which downward sliding is regulated by the tapered portion 111 of the upper end portion coming into contact with the corresponding tapered portion 131b of the insertion hole 131a. Thus, the lid body 131 is held. The core 11 is held so that the upper end protrudes from the surface of the lid main body 131 when held in the lid main body 131 so as to easily come into contact with the lower surface of the absorber 12.

The holding part 132 in the lid part 13 holds the absorbent body 12 in a state where it protrudes outward from the outer peripheral surface of the container body 10 and the surface is exposed to the outside. In this example, specifically, the holding part 132 has a plurality of claw parts 132a and a pressing part 132b. The plurality of claw portions 132a protrude outward from the outer peripheral edge of the lid body 131, and support the absorber 12 from below. The pressing part 132b presses and fixes the absorber 12 from above.

More specifically, in this example, the claw portions 132a are arranged at equal intervals in the outer peripheral direction of the lid body 131. Each claw portion 132a supports the absorber 12 from below so that a gap 133 is formed between the lower surface of the absorber 12 and the surface of the lid body 131. By forming the gap 133, wind from below is easily blown into the gap 133, and vaporization of the essential oil 102 absorbed by the absorber 12 is further promoted. Some of the plurality of claws 132a have a protrusion 132c at the tip. The presser part 132b has an annular frame part 132d and a connecting part 132e that connects the inner periphery of the annular frame part 132d. Several holes 132f are formed in the annular frame 132d. In this example, the projection 132c of the claw 132a and the hole 132f of the annular frame 132d are fitted together so that the claw 132a and the presser 132b are integrated. In addition, if the absorber 12 and the core material 11 can be replaced | exchanged, the fitting structure of the nail | claw part 132a and the holding | suppressing part 132b can be variously changed, without being specifically limited.

In this example, the lid portion 13 further includes a cylindrical body 134 and a float portion 135. The cylindrical body 134 extends from the lid main body 131 toward the inside of the container main body 10, and the core material 11 is inserted therein. The float part 135 is provided so that the outer periphery of the cylinder 134 can move in the cylinder axis direction. The float part 135 is configured to be able to float on the essential oil 102 or the like, and includes a magnet 135a inside. In this example, the magnet 135a is a permanent magnet.

In this example, specifically, the float part 135 is formed in a substantially annular shape, and the cylindrical body 134 passes through the center part. A locking portion 135b is formed on the outer peripheral surface of the lower end portion of the cylindrical body 134 so as to protrude outward in the cylindrical radial direction. The float part 135 is prevented from falling off the cylinder 134 by the locking part 135b. In this example, an example in which the lid portion 13 includes the cylindrical body 134 and the float portion 135 is shown, but the lid portion 13 may not include the cylindrical body 134 and the float portion 135.

Next, the function and effect of the oil container of this example will be described.

The oil container of this example has the above configuration. Therefore, when the essential oil 102 is put into the container body 10, the essential oil 102 is sucked up by the core material 11. The sucked essential oil 102 is absorbed by the absorbent body 12 from the core material 11 and spreads in the surface direction of the absorbent body 12. Here, since the outer shape of the absorber 12 is formed larger than the cylindrical diameter of the container body 10, the absorber 12 is held by the holding portion 132 of the lid portion 13 in a state of protruding outward from the outer peripheral surface of the container body 10. Is done. Moreover, the absorber 12 is hold | maintained by the holding part 132 of the cover part 13 in the state where the surface was exposed outside.

Therefore, when there is wind flowing upward from below the oil container 1, the wind hits a portion of the absorber 12 that protrudes outward from the outer peripheral surface of the container body 10 and is absorbed by the absorber 12. Vaporization of the essential oil 102 is promoted. In this example, the absorber 12 is supported from below by each claw 132a so that a gap 133 is formed between the lower surface of the absorber 12 and the surface of the lid body 131. For this reason, wind from below is easily blown into the gap 133, and vaporization of the essential oil 102 absorbed by the absorber 12 is further promoted. When the essential oil 102 or the like 102 absorbed by the absorber 12 by vaporization decreases, the essential oil 102 or the like is continuously supplied from the core material 11 to the absorber 12.

Therefore, according to the oil container 1 of this example, the essential oil 102 can be easily vaporized continuously.

(Example 2)
The fragrance diffuser of Example 2 will be described with reference to FIGS. As shown in FIGS. 5 to 10, the fragrance diffuser 2 of this example includes a first space portion 21, a second space portion 22, a blower fan 25, and a discharge port 26. This will be described in detail below.

The first space portion 21 includes a placement surface portion 210. The mounting surface portion 210 includes a mounting portion 210a for mounting the oil container 1 capable of sucking out the essential oil or its diluted oil that has entered the container, and a plurality of the mounting surface portion 210a formed around the mounting portion 210a. And a hole 210b.

In this example, specifically, the oil container 1 of Example 1 is used as the oil container 1. The mounting portion 210a is configured such that the surface is one step higher than the portion where the hole portion 210b is formed. An outer peripheral wall 210c is erected on the outer peripheral edge of the mounting portion 210a. With the outer peripheral wall 210c, the oil container 1 can be accurately placed at a predetermined position in the placement portion 210a without being displaced. The plurality of hole portions 210b are formed on the outer periphery of the placement portion 210a at substantially equal intervals.

The fragrance diffuser 2 of this example has a diffuser body 201 on the side on which the oil container 1 is placed, and an outer cover 202 that covers the outer periphery of the diffuser body 201. The first space 21 is formed by covering the diffuser body 201 with the outer cover 202. More specifically, in this example, the diffuser body 201 is formed in a substantially cylindrical shape having an opening 201a on the front side of the outer peripheral surface and a depth space 201b that extends toward the back of the opening 201a. The outer cover 202 is formed in a cylindrical shape. By covering the outer cover 202 from above the diffuser body 201, the opening 201a of the diffuser body 201 is closed by the inner peripheral wall of the outer cover 202, and the first space 21 is formed. Therefore, in this example, the oil container 1 can be taken in and out through the opening 201a of the diffuser body 201 that appears when the outer cover 202 is removed. In addition to this configuration, for example, the door 201 and the shutter (both not shown) are provided in the opening 201a without using the outer cover 202, so that the oil container 1 can be taken in and out. You can also. In this example, the diffuser main body 201 is mainly made of a plastic material, and the outer cover 202 is mainly made of a metal material or a ceramic material.

The second space 22 is arranged below the first space 21. The second space 22 communicates with the first space 21 via the hole 210b. The second space portion 22 has a bottom surface portion 221. An outside air suction port 222 is formed in the bottom surface portion 221. In this example, a plurality of leg portions 223 are provided on the outer surface of the bottom surface portion 221. Therefore, in the fragrance diffuser 2 of this example, a gap 225 is formed below the outer side surface of the bottom surface portion 221, and the outside air is more easily sucked from the outside air suction port 222. In addition, the fragrance diffuser 2 of this example is provided with a filter member 224 in the outside air suction port 222, and is configured so that dust, dust, etc. sucked together with outside air do not enter the second space portion 22. .

The blower fan 25 is disposed in the second space 22. The blower fan 25 is configured to be switched to an on state or an off state by a power switch 271. In this example, specifically, the power switch 271 is provided on the upper part of the fragrance diffuser 2, more specifically on the upper part of the diffuser main body 201. The fragrance diffuser 2 of this example is provided with a power jack 272 on the bottom surface 221 and is configured to receive power from an external power source (not shown) via the power jack 272. Specifically, the power jack 272 is an AC jack. The electric power supplied from the external power source is a part that requires electric power such as the blower fan 25 via the fragrance diffuser 2, more specifically, the wiring (not shown) provided in the diffuser main body 201. Is transmitted to The fragrance diffuser 2 may be configured to operate by a dry battery (not shown) or the like built in the fragrance diffuser 2, more specifically, in the diffuser body 201. In addition, the power switch 271 may have an automatic power-off function that automatically turns off the power at a preset time or an arbitrarily set time. The timer operation unit 273 that operates the automatic power-off function can be provided, for example, on the upper part of the fragrance diffuser 2, more specifically on the upper part of the diffuser main body 201.

The blower fan 25 blows air (arrow A) sucked from the outside air suction port 22 into the first space portion 21 through the hole 210b when the power switch 271 is turned on. In this example, specifically, the blower fan 25 is disposed above the outside air suction port 222. When the power switch 271 is turned on, a fan (not shown) included in the blower fan 25 rotates and air is sucked from the outside air suction port 222. Moreover, in this example, the ventilation flow path 251 for guide | inducing the wind by the ventilation fan 25 to the hole 210b is provided in the ventilation side in the ventilation fan 25. As shown in FIG. Therefore, in this example, the wind by the blower fan 25 is not sent to an unnecessary part in the second space portion 22, and the wind can be reliably sent to the hole 210b.

In this example, the blower fan 25 is configured to be capable of intermittent operation with a plurality of different intermittent operation settings. Therefore, the amount of vaporized essential oil discharged from the discharge port 26 can be appropriately varied according to the size of the space. The fragrance amount adjusting unit 252 for adjusting the fragrance amount by intermittent operation of the blower fan 25 can be provided, for example, at the upper portion of the fragrance diffuser 2, more specifically, at the upper portion of the diffuser main body 201.

The discharge port 26 is formed above the first space portion 21. The discharge port 26 communicates the first space 21 and the outside. In this example, specifically, a third space portion 23 is formed above the first space portion 21. The discharge port 26 is formed so as to penetrate the third space portion 23 between the first space portion 21 and the outside.

In this example, the third space portion 23 is connected to the second space portion 22 via the connection space 24. In the third space 23, a control board 274 and the like for controlling various functions of the fragrance diffuser 2 are arranged. In this example, the connection space 24 is a path through which wiring (not shown) for connecting a functional member such as the blower fan 25 and the control board 274 passes.

The fragrance diffuser 2 of this example further includes a sensor switch 275a that is operated by the magnetic field of the magnet 135a in the float part 135 in the mounting part 210a. In this example, specifically, the sensor switch 275a is a reed switch, and three sensor switches 275a are provided on the back side surface of the mounting portion 210a. The three reed switches are arranged so as to form a substantially triangular shape by each reed switch so that any one of the reed switches operates reliably upon receiving the magnetic field of the magnet 135a in the float part 135. Each sensor switch 275a is connected to the control board 274 by wiring.

The fragrance diffuser 2 of this example has a remaining amount sensor 275. The remaining amount sensor 275 is for notifying that the replenishment time of the essential oil 102 in the oil container 1 has come when the sensor switch 275a is turned on. In this example, specifically, the display unit by the remaining amount sensor 275 is provided on the upper part of the fragrance diffuser 2, more specifically on the upper part of the diffuser main body 201. More specifically, the remaining amount sensor 275 is configured such that the lamp is lit when the sensor switch 275a is turned on.

Next, the effect of the fragrance diffuser of this example will be described.

The fragrance diffuser 2 of this example has the above configuration. Therefore, when the oil container 1 is placed on the placement portion 210a of the first space portion 21 and the power switch 271 is turned on, the blower fan 25 is activated, and the inside of the second space portion 22 from the outside air suction port 222 is activated. External air is sucked into the air. The air sucked into the second space 22 is blown into the first space 21 through the hole 210b. The wind that has flowed into the first space portion 21 flows from the lower side of the oil container 1 toward the upper side along the outer peripheral surface of the oil container 1. At this time, wind hits a portion of the absorbent body 12 that protrudes outward from the outer peripheral surface of the container main body 10, and vaporization of the essential oil 102 absorbed by the absorbent body 12 is promoted. When the essential oil 102 or the like 102 absorbed by the absorber 12 by vaporization decreases, the essential oil 102 or the like is continuously supplied from the core material 11 to the absorber 12. The air containing the vaporized essential oil 102 and the like is discharged from the discharge port 26 above the first space portion 21 to the external space. According to the fragrance diffuser 2 of this example, since the essential oil 102 and the like are sufficiently vaporized, the fragrance can be diffused in a wide space.

The fragrance diffuser 2 of this example has a relatively simple structure because it does not require a compressor or a pump for fragrance diffusion by the essential oil 102 or the like. Moreover, since the fragrance diffuser 2 of this example does not use a nozzle, it is not necessary to perform maintenance of the nozzle. Furthermore, as long as the essential oil 102 is present in the oil container 1, the essential oil can be continuously vaporized, and there is no need to replenish the essential oil as in the oil pod. Therefore, the fragrance diffuser 2 of this example is convenient.

Furthermore, the fragrance diffuser 2 of this example has an upper opening / closing shutter 28. Therefore, by closing the upper opening / closing shutter 28, it is possible to suppress the discharge of the vaporized essential oil 102 from unnecessary discharge ports, and it is easy to suppress the waste of the essential oil 102, etc. In addition, the fragrance diffuser 2 of this example has a lower opening / closing shutter 29. Therefore, by closing the lower opening / closing shutter 29, it is possible to suppress the exhaustion of the vaporized essential oil 102 from the unnecessary outside air suction port 222, and to suppress the waste of the essential oil 102, etc. Cheap.

Further, in the fragrance diffuser 2 of this example, the diffuser body 201 and the outer cover 202 are configured separately, so that the degree of freedom in design selection of the outer cover 222 is improved and the design is excellent. Easy to get.

In addition, the fragrance diffuser 2 of this example can exhibit the following other operational effects. That is, as the essential oil 102 absorbed by the absorber 12 is vaporized, the essential oil 102 stored in the oil container 1 is decreased, and the liquid level of the essential oil 102 is lowered. Then, when the magnet 135a and the sensor switch 275a come close to a distance that allows the sensor switch 275a provided on the mounting portion 210a to be operated by the magnetic field of the magnet 135a in the float portion 135, the sensor switch 275a is turned on. When the sensor switch 275a is turned on, the remaining amount sensor 275 notifies that the replenishment time of the essential oil 102 in the oil container 1 has come. Therefore, the fragrance diffuser 2 of this example can accurately know the replenishment timing of the essential oil 102 in the oil container 1 and can further improve the usability.

As mentioned above, although the Example of this invention was described in detail, this invention is not limited to the said Example, A various change is possible within the range which does not impair the meaning of this invention.
