Description

  The present invention relates to a radiation device that gradually diffuses diffused components such as fragrances and insecticides previously supported on a support such as an adsorbent into the atmosphere or liquid.

  Conventionally, various fragrances that gradually release fragrance components and insecticides that gradually release insecticide components are commercially available. As the fragrance, for example, there is known one in which various volatile fragrance components are dissolved and solidified in paraffin, and the fragrance component is gradually released from the solidified paraffin. In addition, as the insecticide, one that gradually dissipates the insecticidal component absorbed by an adsorbent such as felt by electric heating is known.

Further, as shown in Patent Documents 1 and 2 below, an apparatus for diffusing a deodorant or the like into the atmosphere using ultrasonic vibration is disclosed.
Utility Model Registration No. 3009505 JP-A-8-332425

  In the fragrance as described above, a plurality of fragrance components having different volatility are often blended and used. Therefore, the plurality of fragrance components having different volatility must be uniformly and gradually diffused. However, since the different volatile components are naturally vaporized and diffused from the solidified paraffin, it is extremely difficult to vaporize uniformly. There is a problem that the scent changes with the end of use. Moreover, even with a single fragrance component, it is virtually impossible to control the amount of emission, and although it has a strong scent at first, it is inevitable that the fragrance becomes weak without lasting too long.

  In addition, even with an insecticidal device that uses electric heating, it is virtually impossible to control the amount of radiation, and although it exhibits a strong insecticidal effect at first, it is inevitable that the insecticidal effect will be weakened without lasting too long. . In addition, since electric heating is used, when the insecticide containing a plurality of types of insecticides is evaporated, it has been impossible to control the amount of radiation for each different component. In addition, since electric heating is used, the amount of power used is inevitably increased, and the cost of running, such as an insecticide, that must be continued for a long time such as overnight is further reduced. What can be done is preferred.

  Furthermore, as in Patent Documents 1 and 2 described above, those that atomize a liquid such as a deodorant using ultrasonic vibration destroy the cavitation that occurs in the liquid by applying ultrasonic vibration to the liquid at the liquid level. In this case, droplets are generated by a physical impact force. In this way, since the droplets to be diffused are generated with a physical impact force, there is a limit to reducing the size of the droplets. In order to disperse the droplets over a wide range, an air flow like a fan is separately required. It was necessary to provide a device for generating. Moreover, it was impossible to control the amount of diffusion for each different liquid component.

  This invention is made | formed in view of such a situation, and it aims at provision of the diffusion apparatus which can control the diffusion state of a diffusion component.

  In order to achieve the above object, a radiation device of the present invention is a radiation device that diffuses a radiation component to be diffused, such as a fragrance or an insecticide, and a carrier that carries the radiation component, and the carrier that vibrates. The gist of the invention is that it includes a vibrating body and vibration applying means capable of applying vibration at a frequency that can resonate with the natural frequency of the molecule of the dissipating component.

  That is, since the radiation device of the present invention includes a carrier that carries the radiating component and a vibrating body that vibrates the carrier, the radiated component is ejected from the carrier and diffused by the vibration received by the carrier. . Thereby, it becomes possible to control the dissipating state of the dissipating component by applying an appropriate vibration according to the dissipating component to the vibrating body. That is, the kinetic energy of the molecules (or atoms) constituting the dissipative component itself increases due to the vibrational energy given to the dissipative component via the vibrating body and the carrier, and the molecules (or atoms) themselves jump out individually to the surroundings It will be dissipated. Therefore, rather than mechanically generating droplets using conventional ultrasonic vibrations, it is dissipated by the kinetic energy of the molecules (or atoms) that make up the dissipating component itself, making it much more effective than droplets. It is possible to diffuse the diffused component over a wide range.

  Since the vibration body is provided with vibration applying means capable of applying vibration at a frequency that can resonate with the natural frequency of the dissipative component molecule, the carrier is vibrated at a frequency that resonates with the natural frequency of the dissipative component. When this is done, the molecules (or atoms) of the dissipative component are strongly ejected from the support and dissipate, so that the dissipated state of the dissipative component can be appropriately controlled. Therefore, for example, even when an aromatic component having different volatility is adsorbed and diffused on the carrier, it is possible to prevent the fragrance from changing at the beginning and end of use as in the past. Moreover, it is possible to prevent the fragrance from being weakened without continuing the fragrance.

  In the diffusion device of the present invention, when the surrounding atmosphere medium that dissipates the dissipative component is generated by the vibration of the vibrating body and / or the support, the dissipative component ejected from the support by the vibration is Due to the flow generated in the atmosphere medium, it becomes easy to diffuse to the surroundings, and the dissipated components are effectively diffused to the surroundings. In addition, since the release action of the dissipated component and the diffusion action of the released dissipated component are covered by the vibration of the same vibrator, no special fan device is required, greatly reducing the cost of the device. be able to.

  In the dissipation device of the present invention, a plurality of types of dissipative components are supported on the carrier, and the vibration applying unit appears by switching a plurality of frequencies that can resonate with the natural frequencies corresponding to each of the plurality of types of dissipative components. In the case where the control is performed, the emission state can be appropriately controlled for each of the plurality of types of emission components.

  In the radiation device of the present invention, when a life judging means for judging the life of the carrier by measuring a change in the electric resistance and / or capacitance of the carrier is provided, the radiation component is diffused. It is easy to see that the radiation effect is no longer sustained and inform you when it is time to replace it.

  In the dissipating device of the present invention, when the vibrating body or the vibration applying means is a piezoelectric vibrating body, by controlling a drive signal input to the piezoelectric vibrating body, control of the dissipating state according to the dissipating component and the use situation Can be easily performed. For example, when a plurality of types of dissipative components are supported on the carrier, a desired dissipative component can be dissipated by inputting a drive signal having a frequency corresponding to the type of the dissipative component. In this case, the drive signal having a frequency corresponding to the type of the dissipated component can be switched or repeated depending on the time zone. In addition, it is possible to control the emission intensity of one emission component so as to change depending on the time zone.

  In the radiation device according to the present invention, when the carrier material is replaceable, the radiation effect is recovered by exchanging the whole carrier when the radiation component is diffused and the radiation effect is not sustained. Will be able to.

  Next, the best mode for carrying out the present invention will be described in detail.

  FIG. 1 shows an embodiment of the diffusion device of the present invention. This apparatus includes a diaphragm 1 having a carrier layer 2 formed on a surface thereof, a piezoelectric vibrator 4 including a piezoelectric vibrator that vibrates the diaphragm 1, and a drive signal input to the piezoelectric vibrator 4. And a drive circuit 5 that vibrates.

  In the above apparatus, the piezo vibrator 4 is accommodated in the casing 8 that is open on one side, and the two supports 9 are provided so as to face the vibration surface of the piezo vibrator 4 at a predetermined interval. . The support 9 is made of an elastic material such as rubber, and one end side of the diaphragm 1 is sandwiched and supported between the piezoelectric vibrator 4 and the support 9. In this state, the vibration surface of the piezo vibrator 4 is directly brought into contact with the vibration plate 1 to vibrate the vibration plate 1.

  The diaphragm 1 is detachably supported by a support 9. Thereby, the carrier layer 2 can be easily replaced together with the diaphragm 1. Instead of exchanging the carrier 2 together with the diaphragm 1, it is possible to replace only the carrier 2 with the diaphragm 1 as it is.

  The material of the diaphragm 1 is not particularly limited as long as it has a certain degree of rigidity and can vibrate the carrier layer 2 formed on the surface by itself. Can be applied. For example, it can be composed of various metal materials, resin materials, ceramic materials, and the like.

  The carrier 2 constituting the carrier layer 2 is not particularly limited as long as it can adsorb a dissipating component in advance, and various types can be used. For example, various molecular sieves such as activated carbon, silica gel, activated alumina, ion exchange resin, perlite, some clays, pumice, diatomaceous earth, zeolite, silicalite, porous aluminum phosphate, graphite, porous glass, etc. A porous material can be raised. Further, an aggregate of fibers such as an organic adhesive material and felt, a sponge, and the like can be effectively used as the carrier 2. Furthermore, as the carrier 2, a semipermeable membrane bag filled with a diffusion component such as an aromatic liquid such as aroma oil can be used.

  The release component to be adsorbed and the like on the carrier 2 is not particularly limited, and various kinds of volatile oils such as various fragrances and drugs such as insecticides can be used depending on the purpose. . The dissipative component may be a solid at room temperature or a liquid at room temperature, but in the present invention, the molecule (or atom) itself dissipates due to the kinetic energy of the molecule (or atom). In general, a substance that is in a liquid state at room temperature where the kinetic energy of molecules (or atoms) becomes high to the extent that it starts to dissipate even when the energy applied is small is better.

  These can also be used independently and can also be used in combination of multiple types as needed. That is, a plurality of kinds of dissipating components can be mixed and adsorbed on the porous body, or can be used by filling the bag.

  A piezo vibrator 4 is disposed below the diaphragm 1 supported by the support 9 so that vibration generated by the piezo vibrator 4 can be transmitted to the diaphragm 1. Connected to the piezo vibrator 4 is a drive circuit 5 that inputs a drive signal to the piezo vibrator 4 to generate piezo vibration. The piezo vibrator 4 and the drive circuit 5 function as the vibration applying means of the present invention.

  By doing so, each molecule (or atom) constituting the dissipating component by the vibration received by the carrier 2 is ejected from the carrier 2 and diffused. And it becomes possible to control the dissipating state of the dissipating component by giving an appropriate vibration corresponding to the dissipating component to the diaphragm 1. Therefore, rather than mechanically generating droplets using conventional ultrasonic vibrations, it is dissipated by the kinetic energy of the molecules (or atoms) that make up the dissipating component itself, making it much more effective than droplets. It is possible to diffuse the diffused component over a wide range.

  The dissipation device also includes control means 6 for controlling the drive circuit 5 so that the diaphragm 1 vibrates at a frequency (mass frequency) that can resonate with the natural frequency corresponding to the type of the dissipation component. ing. In this way, when the carrier 2 is vibrated at a frequency that can resonate with the natural frequency corresponding to the type of the dissipative component, the kinetic energy of the molecules (or atoms) constituting the dissipative component is remarkably high due to the resonance phenomenon. Thus, molecules (or atoms) are ejected from the carrier 2 and diffused. For this reason, it becomes possible to control appropriately the diffusion state of a radiation component.

  Here, the frequency at which the diaphragm 1 is vibrated is a frequency that can resonate with the natural vibration frequency of the molecules (or atoms) constituting the dissipative component, and can be easily determined experimentally. Further, the frequency at which the diaphragm 1 is actually vibrated can be appropriately set according to the amount of diffused component diffused per unit time. For example, as shown in FIG. 2, when the diaphragm 1 is vibrated at a frequency close to the natural frequency of the dissipative component, the dissipative intensity of the dissipative component becomes strong, and when it is vibrated at a frequency different from the natural frequency, the dissipative strength is weak. Become. And the amount of radiation per unit time tends to decrease as the difference from the natural vibration frequency of the radiation component increases.

  In the above apparatus, by using the piezo vibrator 4 using a piezoelectric vibrator as the vibrator, the vibration signal such as the frequency of the diaphragm 1 is controlled by controlling the drive signal input to the piezo vibrator 4. In addition, it is possible to easily control the emission state according to the emission component and the use situation.

  That is, for example, as shown in FIG. 3, the control means 6 causes the carrier 2 to adsorb the carrier 2 when a plurality of types of dissipative components (in this case, two components A and B) are carried. It is also possible to control the drive circuit 5 so that a plurality of frequencies that resonate with the natural frequency corresponding to each of the plurality of types of dissipative components A and B are switched. In the example shown in FIG. 3, the timing for mainly diffusing the A component and the timing for mainly diffusing the B component are alternately repeated. In this case, by setting the time ratio between the emission timing of the A component and the emission timing of the B component according to the frequency, it is possible to appropriately control the emission state of each of the plurality of types of emission components A and B.

  Further, as shown in FIG. 4 (a), when the radiation component carried on the carrier 2 is a plurality of types of insecticidal components A, B, and C that are effective for different insects, the target insect is By controlling the frequency so that a large amount of insecticidal components effective against the insects are released during the time when they are likely to appear, the insecticidal components are prevented from being unnecessarily released while exhibiting more effective insecticidal effects. can do. In this example, the frequency is controlled so that the B component is dissipated from early morning to noon, the C component from noon to evening, and the A component from the evening to the next morning.

  Furthermore, as shown in FIG. 4B, when the dissipating component is a fragrance, the frequency can be controlled so that a large amount of the aroma component is dissipated in a time zone in which people go in and out. In this example, the emission intensity is controlled to increase between about 10:00 and 20:00, when people go in and out, and the emission intensity is reduced in other time zones. In addition, when there are a plurality of dissipative components, it is possible to control so that vibrations at frequencies corresponding to the respective dissipative components appear and repeat in order at regular intervals.

  In the above apparatus, the low-frequency vibration of the diaphragm 1 and / or the carrier layer 2 generates a flow in the surrounding atmosphere medium (in this case, air) that dissipates the dissipated components. For example, as shown in FIG. 5, the vibration of the diaphragm 1 is a combination of a low-frequency vibration that is likely to generate an air flow and a natural vibration having a frequency at which the effective component is likely to be diffused. And the generation of airflow can be effectively performed simultaneously. In this case, the frequency of the low-frequency vibration that generates a flow such as an air current is not necessarily constant depending on various conditions such as whether the surrounding atmosphere medium is a gas such as air or a liquid such as water, but is approximately 100 kHz or less. Preferably, it is about 50 kHz or less, more preferably about 40 kHz or less.

  By doing so, the molecules (or atoms) of the dissipative component ejected from the carrier 2 by vibration are easily diffused to the surroundings by the generated air flow, and the dissipative component is effectively dissipated to the surroundings. Further, since the emission action of the dissipated component and the diffusion action of the released dissipative component are covered by the vibration using the same diaphragm 1, no special fan device or the like is required, greatly increasing the cost of the device. Can be suppressed.

  In addition, as shown in the figure, such an airflow generating action is that the diaphragm 1 is supported in a cantilevered manner by the support 9, and the other free end vibrates greatly by applying vibration in the vicinity of the support. In order to work effectively. In this state, it is also possible to control the frequency for radiating the radiated component so as to adjust the radiant intensity of the radiated component or selectively switch the radiated component to be radiated.

  The apparatus uses a conductive material such as a metal plate as the diaphragm 1, and the casing 8 is provided with electrodes 10 that are in contact with the end of the diaphragm 1 and the upper surface of the carrier 2. The apparatus further includes a life determining means 7 for determining the life of the carrier 2 by measuring changes in electrical resistance and / or capacitance between the electrodes 10, that is, between the upper and lower surfaces of the carrier 2. Yes.

  That is, when the amount of the dissipated component carried on the carrier 2 changes, the electrical resistance and capacitance of the carrier 2 change, so that the change detects the remaining amount of the dissipated component carried on the carrier 2. And when it decreases, it is notified by alerting means, such as a warning lamp and a warning. By doing in this way, the user can easily know the life time of the carrier 2 in which the radiation effect has decreased or disappeared, and can promote replacement.

  For example, when the carrier 2 is a non-conductor and the dissipating component is a conductor, the electrical resistance and the capacitance between both electrodes 10 increase as the dissipating component decreases. On the other hand, when the carrier 2 is a conductor and the dissipating component is a non-conducting member, the electrical resistance and the capacitance between the electrodes 10 become lower as the dissipating component decreases.

  Further, in the above apparatus, the lifetime is determined by measuring the electrical resistance between the surface of the carrier 2 and the diaphragm 1, that is, between the upper and lower surfaces of the carrier 2. Even when there is a gradient in the carrying amount of the dissipated component with the vicinity, it is possible to make a more accurate life determination by measuring a numerical value reflecting the entire carrying amount.

  And the said dispersion | distribution apparatus can be used for the dispersion | distribution of the fragrance | flavor component and chemical | medical agent indoors, for example, installing in air | atmosphere, the dispersion | distribution of the chemical | medical agent to water by installing in water.

  FIG. 6 shows a second embodiment of the diffusion device of the present invention.

Other than that, it is the same as that of each said embodiment, and attaches | subjects the same code | symbol to the same part. This apparatus is advantageous when an active ingredient is diffused by vibrating the large carrier 2. Other than that, there exists an effect similar to the said embodiment.

  FIG. 7 shows a third embodiment of the diffusion device of the present invention. In this apparatus, both ends of the diaphragm 1 are supported by support bases 3 and are detachably suspended, so that the carrier layer 2 can be exchanged together with the diaphragm 1. In addition, a piezo vibrator 4 is provided on the lower surface of the diaphragm 1 supported at both ends so as to apply vibration to the diaphragm 1. Other than that, it is the same as that of the said embodiment, and the same code | symbol is attached | subjected to the same part. This device also has the same effects as the above embodiment.

  FIG. 8 shows a fourth embodiment of the diffusion device of the present invention. In this apparatus, the carrier layer 2 is not formed on the surface of the diaphragm 1, but the diaphragm 11 itself is formed from the carrier 2. Other than that, it is the same as that of each said embodiment, and attaches | subjects the same code | symbol to the same part. This device also has the same effects as the above embodiment.

  In each of the above-described embodiments, the piezo vibrator 4 is used as the vibration applying means for applying vibration to the diaphragms 1 and 11 and the like. However, the present invention is not limited to this, and a speaker, a buzzer, an eccentric motor, etc. Various types can be used as long as the diaphragms 1 and 11 can be vibrated. Moreover, in each said embodiment, although the plate-shaped diaphragms 1 and 11 were illustrated as a vibrating body, the shape of a vibrating body is not limited to plate shape, Various shapes can be employ | adopted. In the above embodiment, the diaphragm 1 is exchanged together with the carrier layer 2. However, the present invention is not limited to this, and only the carrier layer 2 may be exchanged.

  As described above, according to the dissipating device of the present invention, it is possible to control the dissipating state of the dissipating component by applying an appropriate vibration corresponding to the dissipating component to the vibrating body. That is, the kinetic energy of the molecules (or atoms) constituting the dissipative component itself increases due to the vibrational energy given to the dissipative component via the vibrating body and the carrier, and the molecules (or atoms) themselves jump out individually to the surroundings It will be dissipated. Therefore, rather than mechanically generating droplets using conventional ultrasonic vibrations, it is dissipated by the kinetic energy of the molecules (or atoms) that make up the dissipating component itself, making it much more effective than droplets. It is possible to diffuse the diffused component over a wide range.

  Since the vibration body is provided with vibration applying means capable of applying vibration at a frequency that can resonate with the natural frequency of the dissipative component molecule, the carrier is vibrated at a frequency that resonates with the natural frequency of the dissipative component. When this is done, the molecules (or atoms) of the dissipative component are strongly ejected from the support and dissipate, so that the dissipated state of the dissipative component can be appropriately controlled. Therefore, for example, even when an aromatic component having different volatility is adsorbed and diffused on the carrier, it is possible to prevent the fragrance from changing at the beginning and end of use as in the past. Moreover, it is possible to prevent the fragrance from being weakened without continuing the fragrance.
