Description

  The present invention relates to a fragrance device.

  Conventionally, a sniffing (Sniff-GC (gas chromatography)) system is known as a system for identifying a component of a sample using odor (fragrance). This Sniff-GC system is a system in which a user detects a smell by smelling a specific sample and identifies a component of the sample from the detected smell.

  In this Sniff-GC system, each component separated by GC is sent to detectors such as FID (Flame Ionization Detector) and MS (Mass Spectrometry) and the smell sniffing port, and the user sniffs the smell. The detection accuracy of the Sniff-GC system is improved by detecting the same component as the component smelled at the port with a detector such as FID or MS.

  By the way, the fragrance device used in such a Sniff-GC system is required to supply a user (gas) containing a desired concentration of fragrance (odor) to the user in a desired time width, As such a conventional perfume device, the perfume device currently disclosed by patent documents 1-3 can be mentioned, for example.

  According to the fragrance supply device disclosed in Patent Document 1, the fragrance agent supplied to the fragrance absorber and the amount of air sent through the flow path from the fragrance absorber to the fragrance can be adjusted, respectively. And air volume can be adjusted easily. In addition, by providing a plurality of fragrance agent supply units, and individually controlling these fragrance agent supply units, it is possible to supply a desired fragrance from a plurality of fragrance agent supply units, and select from a plurality of fragrance agent supply units Two or more desired aromas can be blended in a desired blending amount.

  Moreover, according to the fragrance spraying device disclosed in Patent Document 2, nitrogen for spraying is supplied from a nitrogen gas cylinder to the two-fluid nozzle, and the fragrance in the fragrance tank is pressurized as a gas for spraying the fragrance. Therefore, it is not necessary to use compressed air for spraying the fragrance, and the compressor can be omitted from the fragrance spraying apparatus.

  Further, according to the scenting device disclosed in Patent Document 3, the scent can be generated only when the compressor is operated, and the intensity of the scent can be easily adjusted by adjusting the number of times the compressor is operated, the amount of air blown, and the like. Can be adjusted.

  However, in the fragrance supply device disclosed in Patent Document 1, the fragrance agent delivered to the fragrance absorber by the air supply pump is sucked together with the surrounding air, and the fragrance mixed with the fragrance agent and air is used for air supply. Since the gas is delivered from the discharge port of the pump, there is a possibility that the air supply pump may be contaminated by the fragrance agent, and it becomes difficult to precisely control the concentration of the fragrance. Moreover, since odorless air cannot be sent out, there exists a subject that the pulse-like fragrance which sends out odorless air and a fragrance continuously cannot be formed. For example, in a Sniff-GC system, it is desirable to supply a user with a constant flow rate of fragrance, but when the fragrance concentration and air volume are adjusted, the flow rate of the fragrance to be sent varies greatly. There is also a problem of end.

  Moreover, in the fragrance | flavor spraying apparatus currently disclosed by patent document 2, the pressure regulator which sets the pressure for fragrance | flavor pressurization only between the nitrogen gas cylinder and the fragrance | flavor tank is provided, and the fragrance | flavor sprayed from an injection port is provided. It is difficult to adjust the concentration precisely. Moreover, since the fragrance | flavor in a some fragrance | flavor tank is pressurized at once using the said pressure regulator, there also exists a subject that the fragrance | flavors in a some fragrance | flavor tank cannot be mix | blended with arbitrary compounding ratios.

  Further, in the perfume device disclosed in Patent Document 3, since the compressor and the perfume chamber are in direct communication, odorless air is sent out in the same manner as the aroma supply device disclosed in Patent Document 1. There is a problem that it is not possible to supply a certain amount of aroma.

  The present invention has been made in view of the above-mentioned problems, and can emit odorless gas and fragrance to generate a pulsed fragrance, and can finely adjust the concentration and generation time width of the fragrance. It is a first object to provide a fragrance device. It is a second object of the present invention to provide a fragrance device capable of delivering odorless gases and fragrances having different fragrance concentrations at a substantially constant flow rate.

  In order to achieve the above object, the fragrance device of the present invention is a fragrance agent in fluid communication with at least two introduction portions for introducing odorless gas and a first introduction portion constituting the at least two introduction portions. , A pumping means for pumping odorless gas in fluid communication with the second introduction part constituting the at least two introduction parts, and odorless to the first introduction part and the fragrance room A flow rate adjusting means for adjusting the flow rate of the first fragrance generated by flowing the gas, a mixture of the second fragrance whose flow rate is adjusted by the flow rate adjusting means and the odorless gas pressure-fed by the pressure-feeding means. A mixing amount adjusting unit that adjusts the amount to generate a third aroma and a sending unit for sending the third aroma generated through the mixing amount adjusting unit are provided.

  According to the embodiment described above, the mixing amount adjusting means for adjusting the mixing amount of the aroma whose flow rate is adjusted by the flow rate adjusting means and the odorless gas pressure-fed by the pressure-feeding means to generate the aroma sent from the sending unit is provided. Thus, both odorless gas and fragrance can be sent out from the sending section. In addition, the first introduction unit includes the flow rate adjusting unit that adjusts the flow rate of the first fragrance generated by allowing the odorless gas to flow through the first introduction unit and the fragrance chamber, and the mixing amount adjusting unit. And the flow rate of the first fragrance generated through the fragrance chamber can be adjusted, and the second fragrance whose flow rate is adjusted by the flow rate adjusting means and the mixed amount of the odorless gas pumped are adjusted, Since the concentration of the third aroma sent out from the sending unit can be adjusted, the concentration of the aroma sent out from the sending unit and the time width to be sent out can be finely adjusted. Aroma can be delivered with high accuracy. Further, since the aroma and odorless air are mixed through the mixing amount adjusting means, there is an advantage that the pressure feeding means is not contaminated by the aroma.

  Here, examples of the odorless gas used in the scenting device of the present invention include air and nitrogen.

  Moreover, in one Embodiment of the scenting device of this invention, the said scenting device is introduce | transduced with respect to a said 3rd aroma through the said 1st introducing | transducing part, and the said 1st introducing | transducing part and the said fragrance | flavor An odorless gas branched from a flow path communicating with the chamber and having a flow rate relatively larger than that of the third fragrance is introduced.

  For example, when the concentration (intensity) of the fragrance delivered from the delivery unit is changed, the wind pressure and the air volume of the scent that the user smells at the delivery unit may vary. Therefore, according to the embodiment described above, by introducing an odorless gas having a flow rate relatively larger than that of the third fragrance to the third fragrance, the flow rate of the fragrance sent from the sending section is made substantially constant. It can be maintained, and fluctuations in the wind pressure and air volume of the aroma that the user smells at the delivery section can be suppressed. In addition, the odorless air is introduced through the first introduction part and branched from the flow path connecting the first introduction part and the fragrance chamber, thereby simplifying the configuration of the fragrance device and increasing the manufacturing cost. Can be suppressed. A means for detecting the flow rate of the third fragrance is separately provided, and the fragrance delivered from the delivery unit is adjusted by adjusting the flow rate of the odorless gas introduced into the third fragrance based on the detection value of the detection means. It is also possible to maintain a more uniform flow rate.

  Further, in another embodiment of the perfume device of the present invention, the perfume device comprises a plurality of the perfume chambers, and each perfume chamber is in fluid communication with a unique flow rate adjusting means, The flow rate adjusting means separately adjusts the flow rate of the fragrance generated by allowing odorless gas to flow through each fragrance chamber.

  According to the above-described embodiment, even if the fragrance device includes a plurality of fragrance chambers, the fragrance generated from each fragrance chamber by the respective flow rate adjusting means in fluid communication with each fragrance chamber. The flow rate can be adjusted separately, and the fragrances generated from each fragrance chamber can be blended at an arbitrary blending ratio and sent out from the sending section.

  Moreover, in other embodiment of the scenting device of this invention, the said scenting device is provided with the interruption | blocking means which interrupt | blocks the flow to the said delivery part of the said 3rd fragrance | flavor.

  According to the embodiment described above, when the blocking means is operated, the third fragrance generated by mixing the second fragrance and the odorless gas does not flow to the delivery section, and the delivery of the fragrance from the delivery section is reliably suppressed. be able to. Thereby, only a high purity odorless gas can be sent out from a sending part, for example, and a pulse-like aroma can be easily formed in a sending part.

  Here, it is preferable that the said fragrance | flavor apparatus is equipped with the temperature adjustment means which adjusts the temperature of the fragrance | flavor agent arrange | positioned in the said fragrance | flavor room | chamber interior.

  The fragrance agent placed in the fragrance chamber is volatile, and the flow rate of the fragrance discharged from the fragrance chamber is temperature-dependent, so the temperature of the fragrance agent placed in the fragrance chamber is adjusted. By doing this, the flow rate of the first fragrance discharged from the fragrance chamber can be precisely adjusted.

  As can be understood from the above description, according to the scenting device of the present invention, both the odorless gas and the scent can be sent out from the sending unit to generate a pulsed scent, and the concentration and generation time of the scent. The fragrance device can adjust the width precisely and can generate fragrances of various concentrations and time widths with high accuracy. Moreover, even if it is a case where odorless gas and various concentrations of fragrances are generated, it becomes a fragrance device that can generate odorless gases and fragrances with a substantially constant flow rate from the delivery unit. When a plurality of fragrance chambers are provided, the flow rate of the fragrance discharged from each fragrance chamber can be individually controlled, and the fragrance device can easily generate various types of fragrances.

It is the block diagram which showed Embodiment 2 of the scenting device of this invention typically. It is the figure which showed typically the relationship between the flow volume of air, and the density | concentration of 1st aroma. It is the block diagram which showed typically Embodiment 3 of the fragrance | flavor apparatus of this invention. It is the figure which showed an example of the density | concentration of the fragrance | flavor in the sending part generated using the fragrance | flavor apparatus shown in FIG.

  Embodiments 1 to 3 of the present invention will be described below with reference to the drawings.

[Embodiment 1]
FIG. 1 is a block diagram schematically showing Embodiment 1 of the scenting device of the present invention.

  This perfume device 50 is, for example, a perfume chamber 11 in which a perfume agent S1 is arranged in fluid communication with two introduction parts 1 and 2 for introducing an odorless gas A such as air and the first introduction part 1. And a pumping means 20 for pumping the odorless gas A in fluid communication with the second introduction unit 2 and a sending unit 7 for sending the generated scent to the user or the like. In addition, since the fragrance | flavor agent S1 has volatility and the flow volume of the produced | generated fragrance has temperature dependence, the temperature of the fragrance | flavor agent S1 arrange | positioned in the fragrance | flavor chamber 11 around the fragrance | flavor chamber 11 is adjusted. The temperature adjustment means 40 which consists of an aluminum block etc. for this is provided, and the temperature in the fragrance | flavor chamber 11 is adjusted to 20 degreeC, for example.

  Here, the silica gel 3 and the activated carbon 5 are disposed between the first introduction unit 1 and the fragrance chamber 11, and the odorless gas A introduced from the first introduction unit 1 passes through the silica gel 3 and the activated carbon 5. After being dried and purified, it is supplied to the perfume chamber 11. The flow path L1 between the activated carbon 5 and the fragrance chamber 11 is branched on the upstream side of the fragrance chamber 11, and the flow path L3 after the branch is a flow rate adjusting valve (flow rate) provided in the flow path connected to the delivery unit 7. (Adjustment means) 31.

  Further, the silica gel 4 and the activated carbon 6 are also arranged between the second introduction part 2 and the pumping means 20, and the odorless gas A introduced from the second introduction part 2 passes through the silica gel 4 and the activated carbon 6. After being dried and purified, the pressure is fed by being adjusted to a predetermined flow rate (for example, 0.2 L / min) by the pressure feeding means 20.

  Further, the fragrance device 50 adjusts the flow rate of the first fragrance K1 generated by causing the odorless gas A to flow through the fragrance chamber 11 on the downstream side of the fragrance chamber 11 (flow rate adjusting means). 15, the second fragrance K2 whose flow rate is adjusted by the flow rate adjusting valve 15 and the odorless gas A (pressured gas) pressure-fed by the pressure-feeding unit 20 on the downstream side of both the flow rate adjusting valve 15 and the pressure-feeding unit 20. A mixing amount adjusting valve (mixing amount adjusting means) 17 for adjusting the mixing amount is provided.

  Thereby, the first fragrance K1 discharged from the fragrance chamber 11 containing the fragrance of the fragrance agent S1 disposed in the fragrance chamber 11 by the odorless gas A supplied to the fragrance chamber 11 is The flow rate is adjusted to become the second fragrance K2 (for example, 0.1 to 5.0 mL / min), and the mixing amount adjustment valve 17 adjusts the mixing amount of the second fragrance K2 and the odorless gas A, so that the third fragrance K3 is obtained. Generated.

  A part of the first fragrance K1 that is no longer necessary in the flow rate adjustment valve 15 is discharged from the discharge unit 8 via the activated carbon 41 and the pump 42.

  The third fragrance K3 generated as described above passes through the odorless gas A having a predetermined flow rate (for example, 1.0 L / min) branched from the flow path L1 on the upstream side of the fragrance chamber 11 and the flow rate adjustment valve 31. It is mixed and sent out from the sending unit 7 as the fourth fragrance K4. At that time, the mixing amount of the third fragrance K3 and the odorless gas A can be adjusted by the flow rate adjusting valve 31, but the flow rate of the odorless gas A mixed with the third fragrance K3 is the same as that of the second fragrance K2. Even if the flow rate of the third fragrance K3 varies somewhat depending on its concentration or the like, the flow rate of the third fragrance K3 has a relatively larger flow rate than the third fragrance K3 generated from the odorless gas A sent from the pressure sending means 20. The flow rate of the fragrance K4 delivered from the delivery unit 7 can be maintained substantially constant.

  Thus, according to the scenting device 50 of the first embodiment, the flow rate adjusting valve 15 that adjusts the flow rate of the first fragrance K1 generated by allowing the odorless gas A to flow through the fragrance chamber 11 and its flow rate. By providing the mixing amount adjusting valve 17 that adjusts the mixing amount of the second fragrance K2 whose flow rate is adjusted by the flow rate adjusting valve 15 and the odorless gas A pressure-fed by the pressure-feeding means 20, both the odorless gas and the fragrance are sent out. In addition to being able to be sent out from the unit 7, it is possible to send out the pulsed fragrance from the sending unit 7 by precisely adjusting the concentration of the scent sent out from the sending unit 7 and the time width of the scent sent out.

  Further, the fragrance device 50 introduces the odorless gas A having a flow rate relatively larger than that of the third fragrance K3 to the third fragrance K3 via the first introduction unit 1 and the flow rate adjustment valve 31. Therefore, the flow rate of the fragrance delivered from the delivery unit 7 toward the user or the like can be maintained substantially constant.

[Embodiment 2]
FIG. 2 is a block diagram schematically showing Embodiment 1 of the perfume device of the present invention. The fragrance device 50A of the second embodiment is different from the fragrance device 50 of the first embodiment in the flow rate adjusting means for the fragrance K1, and the other configuration is substantially the same. Therefore, about the structure similar to the fragrance | flavor apparatus 50 of Embodiment 1, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  Specifically, in this fragrance device 50A, the flow rate adjusting means 13A is disposed between the activated carbon 5A of the flow path L1A and the fragrance chamber 11A, and the odorless gas A introduced from the first introduction part 1A is They are dried and purified through silica gel 3A and activated carbon 5A, adjusted to a predetermined flow rate (for example, 0.1 to 5.0 mL / min) through flow rate adjusting means 13A, and supplied to fragrance chamber 11A.

  A flow rate adjusting means 32A is arranged upstream of the flow rate adjusting valve 31A in a flow channel L3A branched from the flow rate L1A communicating with the first introduction portion 1A and the flow rate adjusting means 13A upstream of the flow rate adjusting means 13A. The odorless gas A branched from the flow path L1A is adjusted to a predetermined flow rate (for example, 1.0 L / min) by the flow rate adjusting means 32A before flowing into the flow rate adjusting valve 31A. . Thereby, the flow rate adjustment valve 31A does not need to adjust the flow rate of the odorless gas A, and for example, a three-way cock can be applied.

  As described above, the first fragrance K1 adjusted to a predetermined flow rate and supplied to the fragrance chamber 11A and containing the fragrance of the fragrance agent S1 disposed in the fragrance chamber 11A and discharged from the fragrance chamber 11A is: The flow rate is adjusted by the flow rate adjusting valve 15A to become the second fragrance K2, and the mixing amount adjusting valve 17A is used to adjust the mixing amount of the second fragrance K2 and the odorless gas A (for example, 0.2 l / min). K3 is generated.

  The flow rate of the first fragrance K1 flowing into the flow rate adjusting valve 15A is adjusted by the flow rate adjusting means 13A. Therefore, the flow rate adjusting valve 15A converts the first fragrance K1 into the mixing amount adjusting valve 17A. It is also possible to perform only flow rate adjustment such as sending to the side or sending to the discharge unit 8A side.

  FIG. 3 is a diagram schematically showing the relationship between the flow rate of air supplied to the fragrance chamber 11A and the concentration of the first fragrance K1 when air is used as the odorless gas, and is supplied to the fragrance chamber 11A. As the air flow rate increases, the concentration of the first aroma K1 increases approximately linearly. Therefore, by controlling the flow rate of the odorless gas A supplied to the fragrance chamber 11A by the flow rate adjusting means 13A, the first fragrance K1 having a desired concentration can be generated in the fragrance chamber 11A.

  The third fragrance K3 generated as described above is mixed with the odorless gas A adjusted to a predetermined flow rate by the flow rate adjustment valve 31A via the flow rate adjustment means 32A, and sent out as the fourth fragrance K4. Sent from 7A.

  Here, in this fragrance device 50A, a shutoff valve 19A for shutting off the flow of the third fragrance K3 to the delivery portion 7A is provided between the mixing amount regulating valve 17A and the flow rate regulating valve 31A. By closing 19A, the third fragrance K3 delivered from the delivery part 7A can be reliably shut off. Thereby, while being able to form a pulse-like aroma more precisely with the sending part 7A, only the odorless gas A with high purity can be sent from the sending part 7A. The third fragrance K3 blocked by the cutoff valve 19A is discharged from the discharge section 8A via the activated carbon 41A and the pump 42A.

  In the fragrance device 50A of the second embodiment, the means for adjusting the flow rate of the first fragrance K1 discharged from the fragrance chamber 11A is the flow rate adjusting means 13A disposed on the upstream side of the fragrance chamber 11A and the fragrance chamber. Although it is configured by the flow rate adjustment valve 15A disposed on the downstream side of 11A, only one of them can be applied. For example, by applying only the flow rate adjusting means 13A, the flow rate and concentration of the first fragrance K1 generated by adjusting the flow rate of the odorless gas A supplied to the fragrance chamber 11A can be controlled.

  Further, in order to simplify the configuration of the mixing amount adjusting valve 17A, for example, a three-way cock or the like in which the flow rate adjusting function is omitted is applied. In the mixing amount adjusting valve 17A, the second supplied through the flow rate adjusting valve 15A. When the fragrance K2 and the odorless gas A supplied via the pressure feeding means 20A are mixed without adjusting the flow rate and it is not necessary to send out the fragrance from the delivery section 7A, the third fragrance K3 is removed by the shutoff valve 19A. It may be shut off and discharged. Even in such a case, since the odorless gas A having a predetermined flow rate is supplied to the sending unit 7A via the first introduction unit 1A, the flow rate adjusting means 32A, etc., the user or the like sends the odorless gas from the sending unit 7A. It is no longer possible to determine the presence of a fragrance based on fluctuations in the flow rate (strength) of the gas to be produced.

  Further, if the fragrance device 50A includes a means (not shown) for detecting the flow rate of the third fragrance K3, the flow rate adjusting means 32A is controlled based on the detection value of the detection means to control the third fragrance K3. It is possible to adjust the flow rate of the odorless gas A that is introduced into the gas flow, and to maintain the flow rate of the fourth fragrance K4 that is sent out from the sending unit 7A more uniformly.

Further, on the downstream side of the flow rate adjusting valve 15B and the pressure feeding means 20B, a mixing amount of the second fragrance K21 whose flow rate is adjusted by the flow rate adjusting valve 15B and the odorless gas A (pressure gas) pressure-fed by the pressure feeding means 20B is provided. A mixing amount adjusting valve 17B to be adjusted is disposed, and on the downstream side of the flow rate adjusting valve 16B and the mixing amount adjusting valve 17B, the second aroma K22 whose flow rate is adjusted by the flow rate adjusting valve 16B and the mixing amount adjusting valve. A mixing amount adjusting valve 18B for further adjusting the mixing amount of the fragrance K31 whose mixing amount is adjusted by 17B is provided.

  As described above, the flow rate adjusting means 13B, 14B, the flow rate adjusting valves 15B, 16B, and the mixing amount adjusting valves 17B, 18B are in fluid communication with the fragrance chambers 11B, 12B, respectively. By controlling the flow rate adjusting valves 15B and 16B and the mixing amount adjusting valves 17B and 18B by appropriately closing them, only the fragrance discharged from one fragrance chamber can be sent out from the sending unit 7B. Further, for example, by appropriately adjusting the opening degree of the flow rate adjusting means 13B, 14B, the flow rate adjusting valves 15B, 16B, and the mixing amount adjusting valves 17B, 18B, the aroma discharged from each of the perfume chambers 11B, 12B is appropriately mixed. And a fragrance having a desired fragrance can be delivered from the delivery part 7B.

  FIG. 5 is a diagram showing an example of the concentration of the fragrance generated using the fragrance device 50B shown in FIG. 4, and as described above, the flow rate adjusting means 13B, 14B, the flow rate adjusting valves 15B, 16B, the mixing amount By appropriately controlling the regulating valves 17B and 18B and the shut-off valve 19B, the fragrance discharged from the fragrance chambers 11B and 12B is made into a pulse shape closer to a rectangular wave while precisely controlling the concentration and generation time width of the fragrance. Can be sent from the sending unit 7B.

  In the illustrated example, the fragrance device 50B including the two fragrance chambers 11B and 12B has been described. However, when three or more fragrance chambers are provided, more types of fragrances can be generated.
