Summary of the Invention

Problems to be Solved by the Invention

[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 scent.

[0008] Therefore, the configurations of the spraying devices described in Patent Documents 1 to 3 do not anticipate frequent switching of the liquid to be atomized. For example, they cannot create a new fragrance by blending multiple types of fragrances according to the user's wishes, and switch between fragrances depending on the situation.

[0009] In view of the above circumstances, the present invention aims to provide a fragrance spraying device that can blend and spray a fragrance desired by the user. [Means for solving the problem]

[0010] The fragrance spraying device of the present invention comprises a fragrance supply unit that supplies multiple types of fragrances by dropping them, a fragrance blending unit that mixes the multiple types of fragrances supplied by the fragrance supply unit, and a spraying unit that atomizes and sprays the fragrances mixed in the fragrance blending unit. [Effects of the Invention]

[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.

Embodiment for Implementing the Invention

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

[0014] The perfume spraying device main body 1 of the present embodiment mixes multiple types of perfumes at an arbitrary ratio to generate a perfume with an arbitrary scent and sprays it. Specifically, as shown in FIG. 1, the perfume spraying device main body 1 of the present embodiment includes a perfume - blending and spraying unit 10, a cartridge unit 20, a water - supply unit 30, and a waste - liquid unit 40. The waste - liquid pump 41 of the perfume - blending and spraying unit 10, the cartridge unit 20, the water - supply unit 30, and the waste - liquid unit 40 is housed within a rectangular - parallelepiped - shaped frame F.

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

[0016] The perfume dropping nozzles 11 - 15 drop perfumes and supply them to the perfume - blending pool 17. The perfume dropping nozzles 11 - 15 drop different perfumes respectively. As shown in FIG. 2, the perfume dropping nozzles 11 - 15 are arranged at the same height in the left - right direction.

[0017] As shown in FIG. 2, the fragrance dropping nozzles 11 to 15 each have a tapered nozzle that narrows toward the lower tip, and drops the fragrance from the lower tip. The tapered nozzle is formed of, for example, resin or the like, and it is desirable to use a material for the tapered nozzle that is difficult for the fragrance to adhere to.

[0018] The fragrance dropping nozzles 11 to 15 are configured to be able to drop an arbitrary amount of fragrance respectively under the control of a control unit 50 described later. Each of the fragrance dropping nozzles 11 to 15 drops the fragrance according to a predetermined mixing ratio, and the adjustment of the amount of each dropped fragrance will be described in detail later.

[0019] A flavoring pool 17 is provided below the fragrance dropping nozzles 11 to 15. FIG. 3 is a view of the flavoring spray unit 10 shown in FIG. 2 as seen from the front, and FIG. 4 is a cross-sectional view taken along line A-A of the flavoring spray unit 10 shown in FIG. 3.

[0020] As shown in FIGS. 2 and 3, the flavoring pool 17 is formed in an inverted trapezoidal box shape and has a pool structure for storing a plurality of types of fragrances dropped from the fragrance dropping nozzles 11 to 15. The upper surface of the flavoring pool 17 is open, and the tip portions of the fragrance dropping nozzles 11 to 15 are inserted into the opening. On the other hand, a spraying element 18 is connected to the bottom surface of the flavoring pool 17. As shown in FIGS. 2 and 3, the spraying element 18 is provided at the right end of the bottom surface of the flavoring pool 17, and an inclined surface 17a that slopes downward toward the spraying element 18 is formed from the left side surface of the flavoring pool 17. A water supply pipe 16 (water inlet) is provided above the left side surface of the flavoring pool 17 in the vertical direction. Also, the rear surface 17b on the rear side of the flavoring pool 17 slopes downward and forward as shown in FIG. 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 fragrance dispensing nozzle 11-15 based on the input captured images. The control unit 50 adjusts the amount of fragrance dispensed from each fragrance dispensing nozzle 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 section 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 section 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). The 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 measuring 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 11-15 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 11-15. 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 dispensed from each fragrance dispensing 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 the desired mixing ratio of fragrances 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 dispensed from each of the fragrance dispensing nozzles 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 (for example, 10 μl) of fragrance A 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 to adjust 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 fragrances B to E are adjusted based on the amount of fragrance A, which is the standard fragrance. In the above explanation, fragrance A was used as the standard fragrance, but it is not limited to this; any of fragrances B to E may be used as the standard fragrance. Alternatively, the control unit 50 may determine the standard fragrance based on the remaining amounts of each fragrance A to E. Specifically, the control unit 50 may use the fragrance with the smallest remaining amount detected by the remaining amount detection unit 27 as the standard fragrance.

[0042] Then, after the adjustment of the amounts of fragrances B to E as described above, the control unit 50 controls the water supply pump 32 to supply water to the fragrance blending pool 17, thereby washing away the fragrances A to E used in the adjustment, and controls the waste liquid pump 41 to discharge them as waste liquid.

[0043] In the above explanation, fragrances A to E were sequentially dropped from fragrance dropping nozzles 11 to 15, and the droplets were photographed by camera 26. However, the method is not limited to this; fragrances A to E may also be dropped simultaneously from fragrance dropping nozzles 11 to 15, all droplets of fragrances A to E may be photographed simultaneously, and the amounts of fragrances A to E may be adjusted based on the captured images. In this case as well, one of fragrances A to E is set as the standard fragrance, and the amounts of fragrances other than the standard fragrance are adjusted based on the amount of droplets of the standard fragrance and the desired mixing ratio.

[0044] Furthermore, while the above explanation described how to adjust the amounts of all fragrances A through E, if only some of fragrances A through E are used to produce the desired fragrance, only the amount of those fragrances used will be measured and adjusted.

[0045] Next, after adjusting the amounts of each fragrance A to E as described above, we will explain the process of mixing the adjusted amounts of each fragrance A to E to produce a fragrance with the desired scent, and then spraying it, referring to the flowchart shown in Figure 7. Here, we will assume that water is added to the mixed fragrance of each fragrance A to E to adjust the concentration and produce the final fragrance to be sprayed.

[0046] First, the control unit 50 controls the water supply pump 32 to draw water from the water supply bottle 31 and supply the drawn water to the fragrance blending pool 17 through the water supply pipe 16 (S30). The water supplied here is for concentration adjustment, as described above. The amount of water for concentration adjustment is set in advance by the user, but in S30, a portion of that amount of water is supplied to the fragrance blending pool 17. Specifically, for example, if a total of 1500 μl of water is supplied, half of that, 750 μl, is supplied.

[0047] Then, when supplying water in S30, the water supply pump 32 is controlled so that the flow rate of the water fills the flow path width at the connection point between the waste liquid pipe 19 and the spray element 18. For the water flow rate to fill the flow path width means that the entire flow path at the connection point is filled with water.

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

[0049] Furthermore, in this embodiment, if fragrances A to E are supplied to the blending pool 17 first, rather than water being supplied first, the amount of fragrances A to E is very small compared to water, and since they are dispensed from fragrance dropping nozzles 11 to 15, it is not possible to supply them at a flow rate that fills the flow path width of the connection part of the waste liquid pipe 19.

[0050] Furthermore, fragrances generally use essential oils, which have low surface tension. Therefore, when fragrances A to E are dropped into the dry blending pool 17, they cannot be retained at the connection point of the waste liquid pipe 19, and there is a risk that the supplied fragrances A to E will flow out of the waste liquid pipe 19.

[0051] Therefore, in this embodiment, as described above, water is supplied before fragrances A to E. Since water has high surface tension and the downstream side of the wastewater pipe 19 is blocked by the wastewater pump 41, the supplied water stops at the inlet of the wastewater pipe 19, and an air layer is formed inside the wastewater pipe 19, allowing the water to be retained.

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

[0053] The fragrances A through E, which are dripped in following 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 through the water supply pipe 16 (S34). This mixes the water and fragrances A to E in the desired mixing ratio. Additionally, 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 spraying 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 spraying element 18 (S38). The control unit 50 then 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 mentioned above, the waste liquid pump 41 discharges waste liquid from the fragrance pool 17 and the atomizing element 18. However, by reversing 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 air AR and mixed uniformly.

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

[0059] As shown in Figure 9, a waste liquid pipe 43 is connected to the waste liquid pump 41, which then 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] Furthermore, the control unit 50 reverses the waste liquid pump 41 during the fragrance blending process. That is, it does so 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 11-15 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 with 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 surface tension of the water allows the water to be retained at the connection portion (inlet) of the waste liquid pipe 19.

[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.
