It is designed to be discharged and volatilized outside the container from the discharge port.

[0003]

In any of the above devices, since the drug-containing drug product is arranged in the air passage, the air flow from the fan passes between the drug products. Since it receives resistance in the meantime, its capacitance must be increased. Further, for example, at the design stage, the form and size of the formulation are restricted by the place to be placed in the air passage and the space at that place, which limits the types of drugs that can be used and the amount of drug used. There is a problem that the application range of the preparation is narrowed due to the limitation.

Further, depending on the form and size of the designed formulation, it is necessary to increase the space at the location where it is placed, or to design a new location. However, there is a problem in that the structure of the device becomes complicated and the cost of the device becomes high and the handling becomes difficult. Further, the above-mentioned conventional device is not suitable for large-scale use of a drug.

The present invention has been made in view of the above, and it is possible to easily design a drug carrier and an air blowing section, and to use a large number of drugs and a large amount of a drug volatilization device. The purpose is to provide.

[0006]

In order to achieve the above object, a drug volatilizing device according to the present invention comprises a cylindrical drug carrier for carrying a volatile drug on the air discharge side of an air blowing section. The airflow from the blower unit is detachably attached so as to be discharged to one side end along the inner peripheral surface.

In the above-mentioned drug volatilization apparatus, a drug holding part for holding the drug carrier is provided on the air discharge side of the air blowing part, and the drug holding part is fitted with the outer peripheral surface of the drug carrier. Alternatively, it is configured as a short tubular holding frame for fitting and holding one end of the drug carrier.

Further, the drug carrier has a multi-layered structure, is expandable and contractible, and can be axially connected by a connecting tool.

[0009]

[Operation] The air flow discharged from the air discharge side of the air blower is discharged from one side end side along the inner peripheral surface of the drug carrier. At this time, the volatilized drug that has volatilized from the inner peripheral surface of the drug carrier is diffused to the outside by this air flow.

The drug carrier is held by fitting it into the cylinder of the drug holding portion, or by fitting one end of this into the holding frame.

The drug carrier having a multi-layered structure can be used for a long period of time by expanding and contracting it to change the volatilization area, and by sequentially consuming it from the inside. .

[0012] Further, in the above drug carrier which can be continuously connected by a connecting tool, the volatilization amount and the volatilization time can be increased or decreased by changing the number of connections.

The medicine holding unit 2 of the form shown in FIG. 2 is constituted by a short cylindrical holding frame 10 having a diameter smaller than the size of the fan side end of the blower unit 1 and shortened in the axial direction. The air flow from 4 flows out from the inside of the holding frame 10 to the outside. Then, one end of the drug carrier 9 formed in a cylindrical shape on either the outside or the inside of the holding frame 10 is fitted and held.

The drug carrier 9 is obtained by impregnating a carrier made of pulp or the like with a volatile drug, and molding this into a cylindrical shape. A non-breathable barrier such as a coating film or a film is provided on the outer peripheral surface of this.

In the above structure, the rotation of the fan 4 sucks air through the suction hole 7 provided in the frame 6 of the blower unit 1 and holds the medicine held in the cylindrical body 8 of the medicine holding unit 2 or the holding frame 10. It flows along the inner peripheral surface of the body 9 and is discharged to the outside from the tip thereof. Then, the chemical vapor that has been volatilized to the inner peripheral surface side of the chemical carrier 9 rides on the air flow at this time and diffuses to the outside.

As described above, the drug carrier 9 is formed in a tubular shape so as to be fitted and held in the tubular body 8 or the holding frame 10 of the drug holding portion 2. The form of this is shown in FIGS. 3 to 11.
Various types are possible as shown in FIG.

A variety of cross-sections such as 7 shown in FIG. 7 can be used depending on the shape of the holding frame 10. In addition, as the cross-sectional shape, other shapes such as a quadrangle, a rhombus, and an ellipse can be mentioned.

As shown in FIG. 8, a wind tunnel frame 11 which can be held by a holding frame 10 may be prepared, and the drug carrier 9 may be fitted therein. In this case, the drug carrier 9 can be pulled out from the wind tunnel frame 11 so that it can be used by pulling it out at the time of use. Also, the withdrawal changes the force of the wind passing inward, thereby releasing the volatile drug. Can be adjusted.

Further, as shown in FIG. 9, this wind tunnel frame 11
The drug carrier 9 may be fixed to the inner surface of the substrate by coating, laminating or the like.

The wind tunnel frame 11 may be made of any material that does not allow an air flow to pass, and examples thereof include plastic, metal, wood, porcelain, glass, and barrier processed paper.

Further, as shown in FIG. 10, each of the drug carriers 9 described above may be internally provided with a cross-shaped partition 9b such as reinforcement, if necessary. Further, as shown in FIG. 11, it is also possible to prepare a connector 12 into which the end portion of the drug carrier 9 is fitted, and thereby to connect the two drug carriers 9, 9 to use. In this case, both of the drug carriers 9 and 9 can carry the same amount of the volatile drug, or can carry the different amount of the volatile drug. Alternatively,
It is also possible to connect three or more drug carriers. And thereby, the length of the drug carrier can also be changed.

The material of the drug carrier 9 used in the present invention is only required to be capable of volatilizing a volatile drug, and examples thereof include paper, synthetic paper, wood, synthetic resin, earthenware, natural fiber and synthetic fiber. As described above, these materials may be used in the form of a cylinder, a sheet, a molded product such as a film, or a processed product such as coating or lamination.

Further, as the volatile agents, there are conventionally used insecticides such as insecticides, insect repellents and growth control agents, or various agents used for deodorant, aroma, antibacterial, antifungal and the like. Can be mentioned. Specific examples thereof include the following.

(Pest control agent) Pyrethroid insecticide: allethrin, dl.d-T80-allethrin, dl.d-
T-allethrin, d.d-T-allethrin, d.d-T
80-praletrin, resmethrin, dl.d-T80
-Resmethrin, Empentrin, Terrarethrin, Transfluthrin, Flamethrin, Phenothrin, Etofenprox, Tefluthrin, Fenfluthrin, etc.

In addition to these, pyriproxyfen, methoprene, hydroprene, phenoxycalp, etc. are used as pest growth control agents, and diet, dimethyl phthalate, dibutyl phthalate, 2-ethyl-, as pest repellents.
1,3-hexanediol, p-dichlorobenzene, capric acid diethylamide, camphor, etc. are further added to functional natural essential oils such as anise oil, orange oil, cassia oil, grapefruit oil, perilla oil, clove oil, citronella oil, Examples include cinnamon oil, peppermint oil, hiba oil, cypress oil, peppermint oil, eucalyptus oil, lemongrass oil, geranium oil, and fennel oil.

(Deodorant) Citronella oil, lemongrass oil, bornyl acetate, methyl benzoate, ethyl benzoate, ethyl phenylacetate and the like.

(Fragrance) Natural fragrances of animal or plant origin, or artificial fragrances such as hydrocarbons, alcohols, aldehydes, ketones, lactones, oxides and esters.

(Antibacterial and antifungal agent) Ethyl alcohol, isopropyl alcohol, phenol, thymol, o-phenylphenol, hinokithiazole and the like.

As a power source for driving the fan of the blower unit 1,
Although an example using the battery 13 is shown in each of the above-mentioned embodiments,
This does not matter as long as it is a power source capable of driving the motor 5, such as an AC or DC power source. From the viewpoint of taking advantage of the high evaporation efficiency, which is a characteristic of the present invention, a DC power source using a nickel cadmium, lithium, hydrogen rechargeable battery, a solar battery, etc. is preferable in addition to the alkaline and manganese dry batteries.

The fan 4 of this apparatus is not limited as long as it has a blowing function. Examples include sirocco fans and propeller (axial flow) fans. Further, the selection of the motor is arbitrary according to the above-mentioned power supply and fan, but in terms of utilizing the high volatilization efficiency which is the characteristic of the present invention, the current consumption when the power supply, fan and motor are combined and driven is 5 to 5. About 300 mA is preferable.
If it is 5 mA or less, the blowing capacity is too weak, and if it is 300 mA or more, the power is consumed so much that the life of the dry battery is too short. In addition, the air flow rate during driving depends on the application, but it is 0.
1 to 15 m / sec and an air flow rate of 0.5 to 30,000 L / min are effective.

In the above-described embodiment of the present invention, when the amount of the volatile drug to be volatilized is increased or the drug which is relatively hard to volatilize is volatilized, a heating means is provided in the blower unit 1 to blow air to the drug holding unit 2. The air to be heated may be heated.

[0038]

According to the present invention, the air flow from the air blower flows along the inner peripheral surface of the drug carrier so that the drug evaporated on the inner peripheral surface of the drug carrier can be diffused to the outside. The air flow from the air blower is discharged to the outside with almost no resistance, and the fan of the air blower can be made smaller than the amount of the drug volatilized from the drug carrier, which reduces the air blower. The size can be reduced and the structure can be simplified.

Further, since the drug carrier is cylindrical, the drug carrier and the air blower can be easily designed.

Further, since the drug carrier is detachably attached to the air blower, it is possible to selectively use the drug carriers of different drugs for one air blower.

Since the drug carrier has a multiple structure or can be connected, the capacity of the drug carrier can be increased or decreased as necessary.
