Description

Fragrance Spraying Device

[0001] The present invention relates to a fragrance spraying device for spraying fragrances.

[0002] Conventionally, there has been proposed a fragrance spraying device that atomizes a fragrance by an ultrasonic vibrator and diffuses it to enjoy the scent.

[0003] For example, Patent Document 1 proposes a spraying device that includes an ultrasonic vibrator in a liquid and atomizes the liquid by ultrasonic waves.

[0004] Further, Patent Document 2 proposes a spraying device that immerses a columnar absorption member in a liquid and atomizes the liquid with an ultrasonic vibrator brought into contact with the absorption member.

[0005] Further, Patent Document 3 proposes a spraying device that vibrates a mesh-like member with an ultrasonic vibrator to atomize the liquid.

[0006] Japanese Unexamined Patent Application Publication No. 2016 - 153117, Japanese Unexamined Patent Application Publication No. 2007 - 61815, Japanese Unexamined Patent Application Publication No. 2020 - 163310

[0007] However, all of Patent Documents 1 to 3 are devices for atomizing a single type of liquid. That is, the spraying devices described in Patent Documents 1 to 3 only assume spraying a single fragrance.

[0008] Therefore, since the configurations of the spraying devices described in Patent Documents 1 to 3 do not assume frequent switching of the liquid to be atomized, for example, according to the user's wishes, it is not possible to blend a plurality of types of fragrances to generate a new fragrance and switch the fragrance according to the situation.

[0009] In view of the above circumstances, an object of the present invention is to provide a fragrance spraying device capable of blending and spraying a fragrance desired by a user.

[0010] The fragrance spraying device of the present invention includes a fragrance supply unit that drops and supplies a plurality of types of fragrances, a fragrance blending unit that blends the plurality of types of fragrances supplied by the fragrance supply unit, and a spraying unit that atomizes and sprays the fragrance blended in the fragrance blending unit.

[0011] According to the fragrance spraying device of the present invention, multiple types of fragrances are supplied from a fragrance supply unit to a fragrance blending unit, and the fragrances blended in the fragrance blending unit are atomized and sprayed by a spraying unit, so that the user's desired fragrance can be blended and sprayed.

[0012] Figure 2 shows a perspective view of the main body of the fragrance spraying device of the present invention. Figure 3 shows a cross-sectional view of the fragrance spraying unit along line A-A. Figure 4 shows a perspective view of the fragrance spraying unit shown in Figure 2, a view from the front of the fragrance spraying unit shown in Figure 3. Figure 5 shows a block diagram showing the configuration of the control system of one embodiment of the fragrance spraying device of the present invention. Figure 6 shows a flowchart for explaining the process of adjusting the amount of multiple types of fragrances. Figure 7 shows a flowchart for explaining the process of generating and spraying fragrances of a desired scent. Figure 8 shows how air is supplied to the fragrance pool. Figure 9 shows a specific configuration example in which the wastewater pump is rotated forward to discharge wastewater when wastewater is present, and the wastewater pump is reversed to supply air to the fragrance pool when fragrance is being blended.

[0013] Hereinafter, an embodiment of the fragrance spraying device of the present invention will be described in detail with reference to the drawings. Figure 1 is a perspective view showing the schematic configuration of the fragrance spraying device body 1 of this embodiment. The up, down, left, right, front, and back directions shown in Figure 1 are the up, down, left, right, front, and back directions of the fragrance spraying device body 1 of this embodiment. The up and down direction shown in Figure 1 is the vertical direction.

[0014] The fragrance spraying device body 1 of this embodiment mixes multiple types of fragrances in any proportion to produce a fragrance of any desired scent, and then sprays it. Specifically, as shown in Figure 1, the fragrance spraying device body 1 of this embodiment comprises a fragrance blending spraying unit 10, a cartridge unit 20, a water supply unit 30, and a waste liquid unit 40. The fragrance blending spraying unit 10, the cartridge unit 20, the water supply unit 30, and the waste liquid pump 41 of the waste liquid unit 40 are housed within a rectangular parallelepiped frame F.

[0015] The fragrance blending spray unit 10 mixes and sprays multiple fragrances. Figure 2 is an enlarged view of the fragrance blending spray unit 10. As shown in Figure 2, the fragrance blending spray unit 10 includes fragrance dropping nozzles 11 to 15, a fragrance blending pool 17, a spraying element 18, a water supply pipe 16, and a waste liquid pipe 19. In this embodiment, the fragrance dropping nozzles 11 to 15 correspond to the fragrance supply unit of the present invention, the fragrance blending pool 17 corresponds to the fragrance blending unit of the present invention, and the spraying element 18 corresponds to the spraying unit of the present invention.

[0016] The fragrance dispensing nozzles 11 to 15 dispense fragrance into the blending pool 17. Each of the fragrance dispensing nozzles 11 to 15 dispenses a different fragrance. The fragrance dispensing nozzles 11 to 15 are arranged at the same height in the left-right direction, as shown in Figure 2.

[0017] As shown in Figure 2, each of the fragrance dispensing nozzles 11 to 15 has a tapered nozzle that narrows towards the lower end, and dispenses fragrance from the lower end. The tapered nozzles are formed from, for example, resin, but it is desirable to use a material that does not easily absorb the fragrance as the material for the tapered nozzles.

[0018] The fragrance dispensing nozzles 11 to 15 are configured to dispense any desired amount of fragrance under the control of the control unit 50, which will be described later. Each of the fragrance dispensing nozzles 11 to 15 dispenses fragrance according to a predetermined mixing ratio, but the adjustment of the amount of each fragrance dispensed will be described in detail later.

[0019] A fragrance blending pool 17 is provided below the fragrance dispensing nozzles 11-15. Figure 3 is a front view of the fragrance blending spraying unit 10 shown in Figure 2, and Figure 4 is a cross-sectional view of the fragrance blending spraying unit 10 shown in Figure 3 along line A-A.

[0020] As shown in Figures 2 and 3, the fragrance blending pool 17 is formed in the shape of an inverted trapezoidal box and has a pool structure for storing multiple types of fragrances dropped from fragrance dropping nozzles 11 to 15. The top surface of the fragrance blending pool 17 is open, and the tips of the fragrance dropping nozzles 11 to 15 are inserted into this opening. On the other hand, a spray element 18 is connected to the bottom surface of the fragrance blending pool 17. As shown in Figures 2 and 3, the spray element 18 is provided at the right end of the bottom surface of the fragrance blending pool 17, and an inclined surface 17a is formed on the left side of the fragrance blending pool 17 that slopes downward toward the spray element 18. A water supply pipe 16 (water inlet) is provided on the vertically upper left side of the fragrance blending pool 17. The rear surface 17b of the fragrance blending pool 17 is inclined downward toward the front, as shown in Figure 4.

[0021] The fragrance dripped from the fragrance dripping nozzles 11-15 and the water supplied from the water supply pipe 16 slide down the inclined surface 17a and back surface 17b of the fragrance mixing pool 17 by their own weight, mix at the bottom of the fragrance mixing pool 17, and then are supplied to the atomizing element 18. The timing of the supply of fragrance from the fragrance dripping nozzles 11-15 and the supply of water from the water supply pipe 16 will be described in detail later.

[0022] The atomizing element 18 atomizes the fragrance (mixed fragrance) supplied from the fragrance pool 17 and sprays the fragrance mist M forward, as shown in Figure 4. The atomizing element 18 has a piezoelectric element and a metal mesh, and generates ultrasonic waves when a voltage is applied, thereby atomizing and spraying the supplied fragrance. Note that already known elements can be used as the atomizing element 18.

[0023] A waste liquid pipe 19 is connected to the spray element 18. When the spraying of a predetermined fragrance (mixed fragrance) by the spray element 18 is completed, water is supplied from the water supply pipe 16 to the fragrance mixing pool 17 in preparation for mixing and spraying the next fragrance, and the fragrance mixing pool 17 and the spray element 18 are cleaned. The waste liquid after cleaning is sucked out from the waste liquid pipe 19 by driving a waste liquid pump 41, which will be described later.

[0024] A camera 26 is provided behind the fragrance dispensing nozzles 11-15. The camera 26 photographs the fragrance being dispensed from the fragrance dispensing nozzles 11-15. The camera 26 photographs, for example, the area R shown by the rectangular frame in Figure 3. The images captured by the camera 26 are output to the control unit 50, which will be described later. The captured images are input to the measurement unit 51 of the control unit 50, and the measurement unit 51 measures the amount of fragrance dispensed from each of the fragrance dispensing nozzles 11-15 based on the input captured images. The control unit 50 adjusts the amount of fragrance dispensed from each of the fragrance dispensing nozzles 11-15 based on the measured amount of fragrance, but the method of adjustment will be described in detail later.

[0025] Returning to Figure 1, the cartridge unit 20 stores the fragrance supplied to the fragrance dispensing nozzles 11-15. The cartridge unit 20 comprises five fragrance cartridges 21-25. Each of the five fragrance cartridges 21-25 stores a different fragrance. The five fragrance cartridges 21-25 and the five fragrance dispensing nozzles 11-15 are connected by supply pipes 21a-25a, and the fragrance stored in the fragrance cartridges 21-25 is supplied to the fragrance dispensing nozzles 11-15 via the supply pipes 21a-25a.

[0026] Furthermore, the cartridge unit 20 is equipped with a remaining amount detection unit 27 (see Figure 5) that detects the remaining amount stored in each fragrance cartridge 21 to 25. The remaining amount detection unit 27 is equipped with an optical sensor or the like and optically detects the remaining amount of fragrance stored in each fragrance cartridge 21 to 25. Note that the remaining amount detection method is not limited to optical detection; other known detection methods can also be used.

[0027] The remaining amount of each fragrance detected by the remaining amount detection unit 27 is output to the control unit 50. When the remaining amount of each fragrance falls below a predetermined threshold, the control unit 50 lights up a warning lamp (not shown) or the like to issue a warning.

[0028] The water supply unit 30 supplies water to the water supply pipe 16 of the fragrance spraying unit 10 described above. Specifically, the water supply unit 30 comprises a water supply bottle 31 and a water supply pump 32. The water supply bottle 31 stores water, and the water supply pump 32 supplies the water stored in the water supply bottle 31 to the water supply pipe 16, thereby supplying water to the fragrance pool 17. The water supply timing and amount of the water supply pump 32 are controlled by the control unit 50.

[0029] The waste liquid unit 40 collects waste liquid from the fragrance spraying unit 10 by sucking it up through the waste liquid pipe 19 of the fragrance spraying unit 10. Specifically, the waste liquid unit 40 includes a waste liquid pump 41 and a waste liquid bottle 42. The waste liquid pump 41 sucks up waste liquid from the fragrance spraying unit 10 through the waste liquid pipe 19. The waste liquid sucked up by the waste liquid pump 41 flows out into the waste liquid bottle 42 via a tube or the like and is stored there. The waste liquid bottle 42 corresponds to the waste liquid storage unit in this invention. The timing of waste liquid suction of the waste liquid pump 41 is controlled by the control unit 50. The waste liquid pump 41 corresponds to the gas supply unit in this invention, but its operation will be described in detail later.

[0030] Figure 5 is a block diagram showing the configuration of the control system of the fragrance spraying device according to this embodiment. The fragrance spraying device body 1 and the control unit 50 shown in Figure 1 are connected, for example, by a communication cable, and the fragrance spraying device body 1 operates in response to a control signal output from the control unit 50. The fragrance spraying device body 1 and the control unit 50 may be connected via a wireless or wired communication line.

[0031] The control unit 50 includes a CPU (Central Processing Unit), semiconductor memory such as ROM (Read Only Memory) and RAM (Random Access Memory), storage such as a hard disk, and a communication interface (I / F). A fragrance control program is installed in the storage of the control unit 50. When this fragrance control program is started by the CPU, the various functions described later are executed.

[0032] The control unit 50 primarily controls the operation of the fragrance dispensing nozzles 11-15, the spraying element 18, the camera 26, the water supply pump 32, and the waste liquid pump 41. The control unit 50 also includes a measurement unit 51 and an adjustment unit 52.

[0033] As described above, the measurement unit 51 acquires the captured image taken by the camera 26 and measures the amount of fragrance dispensed from each fragrance dispensing nozzle 11 to 15 based on the captured image. For measuring the amount of fragrance based on the captured image, for example, the amount of droplets can be calculated by binarizing the captured image and calculating the volume from the projected area of ​​the droplets dispensed from each fragrance dispensing nozzle 11 to 15. Alternatively, the amount of droplets can be determined by inputting the captured image into a pre-trained model that has been machine-learned to understand the relationship between the captured image of a droplet and its amount.

[0034] The adjustment unit 52 adjusts the amount of fragrance dropped from each fragrance dropping nozzle 11 to 15 so that it matches the desired mixing ratio.

[0035] The mixing ratio of each fragrance dropped from each fragrance dropping nozzle 11 to 15 is preset according to the user's desired fragrance, and the control unit 50 controls each fragrance dropping nozzle 11 to 15 so that the amount dropped according to the set mixing ratio is the same as the amount dropped. However, in reality there are errors, and the mixing ratio of the fragrances dropped from each fragrance dropping nozzle 11 to 15 may not be the mixing ratio of the desired fragrance.

[0036] The adjustment unit 52 adjusts for the errors described above so that a fragrance with the desired mixing ratio can be obtained. The adjustment process by the adjustment unit 52 will be explained below with reference to the flowchart shown in Figure 6. Here, the fragrances dropped from each fragrance dropping nozzle 11 to 15 will be referred to as fragrances A to E.

[0037] First, the control unit 50 controls the fragrance dispensing nozzle 11 to dispense a preset amount of fragrance A (for example, 10 μl) according to the mixing ratio (S10). Then, the control unit 50 photographs the droplet of fragrance A with the camera 26, and the measurement unit 51 measures the amount of fragrance A based on the captured image (S12). Here, fragrance A is considered the reference fragrance, and the amount measured in S12 is the amount of the reference fragrance. Note that the amount measured in S12 is not necessarily the preset amount (for example, 10 μl).

[0038] Then, the control unit 50 calculates the amount of fragrance B to be dispensed based on the amount of fragrance A measured in S12 and the mixing ratio desired by the user (S14). Specifically, the control unit 50 calculates the amount of fragrance B to be dispensed by performing the following calculation based on the measured amount of fragrance A and the mixing ratio of the amount of fragrance B to the amount of fragrance A set by the user: Amount of fragrance A (standard fragrance) × Mixing ratio of fragrance A and fragrance B

[0039] Next, the control unit 50 controls the fragrance dispensing nozzle 12 to dispense the amount of fragrance B calculated in S14 (S16). The control unit 50 then uses the camera 26 to photograph the droplets of fragrance B, and the measurement unit 51 measures the amount of fragrance B based on the captured image (S18). The control unit 50 then compares the amount of fragrance B measured in S18 with the amount of fragrance B dispensed calculated in S14, and if there is a discrepancy between the two, it adjusts the amount of fragrance B dispensed from the fragrance dispensing nozzle 12 to eliminate the discrepancy (S20).

[0040] Then, the control unit 50 repeats the processes S14 to S20 for fragrances C to E as well, adjusting the amount of fragrances C to E dispensed (S22). Note that the mixing ratio in the above formula is the mixing ratio of fragrance A and fragrance C when calculating the amount of fragrance C dispensed, the mixing ratio of fragrance A and fragrance D when calculating the amount of fragrance D dispensed, and the mixing ratio of fragrance A and fragrance E when calculating the amount of fragrance E dispensed.

[0041] As described above, the amounts of Flavors B to E are adjusted based on the amount of Flavor A, which is the reference flavor. In the above description, Flavor A is used as the reference flavor, but this is not restrictive, and any one of Flavors B to E may be used as the reference flavor. Further, the control unit 50 may determine the reference flavor based on the remaining amounts of each of Flavors A to E. Specifically, the control unit 50 may use, as the reference flavor, the flavor with the smallest remaining amount detected by the remaining amount detection unit 27 among Flavors A to E.

[0042] Then, after the amounts of Flavors B to E are adjusted as described above, the control unit 50 controls the water supply pump 32 to supply water to the flavoring pool 17 to wash away Flavors A to E used in the adjustment once, and controls the waste liquid pump 41 to discharge it as waste liquid.

[0043] In the above description, Flavors A to E are sequentially dropped from the flavor dropping nozzles 11 to 15, and the droplets are photographed by the camera 26. However, this is not restrictive, and Flavors A to E may be dropped simultaneously from the flavor dropping nozzles 11 to 15, all the droplets of Flavors A to E may be photographed simultaneously, and based on the photographed image, the amounts of Flavors A to E may be adjusted. Also in this case, as in the above, any one of Flavors A to E is set as the reference flavor, and based on the amount of the droplets of the reference flavor and the desired mixing ratio, the amounts of the flavors other than the reference flavor are adjusted.

[0044] In the above description, a method for adjusting the amounts of all of Flavors A to E has been described. However, when only some of Flavors A to E are used to produce a flavor desired by the user, only the amounts of the flavors used are measured and adjusted.

[0045] Next, after the amounts of each of Flavors A to E are adjusted as described above, a process of mixing each of Flavors A to E in the adjusted amounts to produce a flavor with a desired scent and spraying this will be described while referring to the flowchart shown in FIG. 7. Here, it is assumed that water is added to the flavor obtained by mixing each of Flavors A to E to adjust the concentration, and the final flavor to be sprayed is produced.

[0046] First, the control unit 50 controls the water supply pump 32 to suck water from the water supply bottle 31 and supply the sucked water from the water supply pipe 16 to the flavoring pool 17 (S30). The water supplied here is the water for concentration adjustment as described above. The amount of water for concentration adjustment is preset by the user, but in S30, a part of the amount of water is supplied to the flavoring pool 17. Specifically, for example, when a total of 1500 μl of water is supplied, 750 μl, which is half of it, is supplied.

[0047] When supplying water in S30, the water supply pump 32 is controlled so that the flow rate of the water becomes an amount that fills the flow path width of the connection portion between the spray element 18 of the waste liquid pipe 19. That the flow rate of water fills the flow path width means that the entire flow path of the above connection portion is filled with water.

[0048] By controlling the flow rate of water in this way, since the supplied water is a small amount, water can be retained at the connection portion between the spray element 18 of the waste liquid pipe 19 by surface tension. Conversely, if the flow rate of water does not fill the flow path width of the connection portion of the waste liquid pipe 19, there is a risk that water will flow out from the waste liquid pipe 19.

[0049] Also, as in the present embodiment, when the flavoring agents A to E are first supplied to the flavoring pool 17 instead of first supplying water, the amounts of the flavoring agents A to E are very small compared to water, and since they are dropped from the flavoring agent dropping nozzles 11 to 15, they cannot be supplied at a flow rate that fills the flow path width of the connection portion of the waste liquid pipe 19.

[0050] In addition, generally essential oils or the like are used as flavoring agents, and the surface tension is low. Therefore, when the flavoring agents A to E are dropped into the dry flavoring pool 17, the flavoring agents A to E cannot be retained at the connection portion of the waste liquid pipe 19, and there is a risk that the supplied flavoring agents A to E will flow out from the waste liquid pipe 19.

[0051] Therefore, in the present embodiment, as described above, water is supplied before the flavoring agents A to E. Since water has a high surface tension and the downstream side of the waste liquid pipe 19 is blocked by the waste liquid pump 41, the supplied water stops at the inlet of the waste liquid pipe 19, and the inside of the waste liquid pipe 19 becomes an air layer and can retain water.

[0052] Then, after water is supplied as described above, the control unit 50 controls each fragrance dispensing nozzle 11 to 15 to dispense fragrances A to E in the adjusted amounts described above and supply them to the fragrance blending pool 17 (S32). The fragrances A to E may be dispensed in the order of A to E, or they may all be dispensed simultaneously.

[0053] The fragrances A through E, which are dripped after the water supply, are caught by the previously supplied water and do not fall into the waste liquid pipe 19.

[0054] Next, the control unit 50 controls the water supply pump 32 to draw water from the water supply bottle 31 and supply the remaining water to the fragrance blending pool 17 from the water supply pipe 16 (S34). This mixes the water and fragrances A to E in the desired mixing ratio. Furthermore, by introducing water after supplying fragrances A to E, the water and fragrances A to E are stirred, resulting in a uniformly mixed state suitable for atomization.

[0055] Then, after supplying the remaining water, the control unit 50 controls the spray element 18 to generate ultrasonic waves and sprays fragrance from the spray element 18 (S36).

[0056] Then, when spraying from the spray element 18 is finished, the control unit 50 supplies water from the water supply pipe 16 to the fragrance pool 17 in preparation for mixing and spraying the next fragrance, and performs a cleaning process on the fragrance pool 17 and the spray element 18 (S38). Then, the control unit 50 drives the waste liquid pump 41 to suck up the waste liquid after cleaning and discharges it from the waste liquid pipe 19 to the waste liquid bottle 42 (S40). When a new fragrance is to be mixed and sprayed, the process from S30 to S40 is repeated.

[0057] As described above, the waste liquid pump 41 discharges waste liquid from the fragrance pool 17 and the atomizing element 18. However, by reversing the operation of the waste liquid pump 41, air may be supplied to the fragrance pool 17. Figure 8 shows how air AR is supplied into the fragrance pool 17. Note that the atomizing element 18 is omitted from the illustration in Figure 8. As shown in Figure 8, by supplying air AR, the mixture K of fragrances A to E and water stored in the fragrance pool 17 can be stirred by the bubbles of the air AR and mixed uniformly.

[0058] Figure 9 shows a specific configuration when, as described above, the wastewater pump 41 is rotated forward to discharge the wastewater, and when the fragrance is being blended, the wastewater pump 41 is rotated in reverse to supply air to the blending pool 17.

[0059] As shown in Figure 9, a waste liquid pipe 43 is connected to the waste liquid pump 41, which branches into a waste liquid bottle-side waste liquid pipe 44 and an air inlet pipe 45 for introducing air. The waste liquid bottle-side waste liquid pipe 44 is equipped with a check valve 46 that allows waste liquid to flow only from the waste liquid pump 41 towards the waste liquid bottle 42 and prevents backflow, while the air inlet pipe 45 is equipped with a check valve 47 that introduces air from the atmosphere towards the waste liquid pump 41 and prevents backflow.

[0060] With this configuration, when the waste liquid pump 41 is rotating forward, the waste liquid can be directed only to the waste liquid pipe 44 on the waste liquid bottle side, and when the waste liquid pump 41 is rotating backward, backflow of waste liquid from the waste liquid bottle 42 can be prevented, and air can be introduced only through the air inlet pipe 45.

[0061] The control unit 50 reverses the waste liquid pump 41 during the fragrance blending process. Specifically, this is done between steps S34 and S35 in the flowchart shown in Figure 7.

[0062] According to the fragrance spraying device of the above embodiment, multiple types of fragrances are supplied to the fragrance blending pool 17 from fragrance dropping nozzles 11 to 15, and the fragrance blended in the fragrance blending pool 17 is sprayed by the spraying element 18, so that the user's desired fragrance can be blended and sprayed.

[0063] Furthermore, in the fragrance spraying device of the above embodiment, a water supply pipe 16 is provided on the vertically upper side of the fragrance mixing pool 17. This allows the fragrance dropped onto the surface of the fragrance mixing pool 17 from the fragrance dropping nozzles 11 to 15 to be washed away with water and mixed, thus enabling the use of the fragrance without waste.

[0064] Furthermore, in the fragrance spraying device of the above embodiment, the amount of each type of fragrance dropped from the fragrance dropping nozzles 11 to 15 is measured by the camera 26 and the measuring unit 51. Based on the amount of a standard fragrance (fragrance A) measured by the measuring unit 51 and a preset mixing ratio, the amount of fragrances other than the standard fragrance (fragrances B to E) is adjusted. This makes it possible to produce the desired fragrance while suppressing the consumption of fragrances.

[0065] Furthermore, in the fragrance spraying device of the above embodiment, the remaining amount of fragrance stored in each fragrance cartridge 21 to 25 is detected, and the fragrance with the smallest remaining amount is designated as the standard fragrance, thereby reducing the consumption of the fragrance with the smallest remaining amount.

[0066] Furthermore, in the fragrance spraying device of the above embodiment, after water is supplied to the fragrance pool 17, each fragrance is supplied from the fragrance dropping nozzles 11 to 15, and then water is supplied again to mix them. As described above, this prevents the fragrance from falling into the waste liquid pipe 19 and allows for efficient mixing of fragrances A to E and water.

[0067] Furthermore, in the fragrance spraying device of the above embodiment, the flow rate of water supplied to the fragrance pool 17 before each fragrance is supplied is set to an amount that fills the flow path width of the connection portion of the waste liquid pipe 19. As described above, the water can be retained at the connection portion (inlet) of the waste liquid pipe 19 by the surface tension of the water.

[0068] Furthermore, in the fragrance spraying device of the above embodiment, air AR is supplied to the fragrance pool 17 from the waste liquid pipe 19, so that the fragrances A to E and water stored in the fragrance pool 17 can be stirred by the bubbles of air AR and mixed uniformly, as described above.

[0069] Furthermore, by reversing the waste liquid pump 41 to supply air to the fragrance blending pool 17, air can be supplied without installing any new mechanisms, thereby reducing costs.

[0070] Furthermore, in the fragrance spraying device of the above embodiment, the waste liquid pipe 43 is branched into a waste liquid bottle side waste liquid pipe 44 and an air introduction pipe 45 for introducing air, a check valve 46 is provided in the waste liquid bottle side waste liquid pipe 44 and a check valve 47 is provided in the air introduction pipe 45. As described above, when the waste liquid pump 41 is rotating forward, the waste liquid can flow only through the waste liquid bottle side waste liquid pipe 44, and when the waste liquid pump 41 is rotating in reverse, backflow of waste liquid from the waste liquid bottle 42 is prevented and air can be introduced only through the air introduction pipe 45.

[0071] Furthermore, the present invention is not limited to the embodiments described above, and the components can be modified and implemented in practice without departing from the spirit of the invention. Also, various inventions can be formed by appropriate combinations of the multiple components disclosed in the embodiments.
