Description

  The present invention relates to a smoke method, a smoke device unit, and a smoke device.

In general households, treat indoor spaces, vehicle interiors, etc. with a fumigant (fumigant) to control pests, such as sanitary pests such as flies, mosquitoes and cockroaches, molds and bacteria. Things have been done.
Smoke agents include solid preparations mainly composed of a combustion base and active ingredients such as insecticides and bactericides. As the combustion base, nitrocellulose, azodicarbonamide, 4,4′-oxybis (benzenesulfonylhydrazide), N, N′-dinitrosopentamethylenetetramine and the like are generally used.
When the smoke agent is heated at the time of use, the combustion base is burned or decomposed to generate smoke (gas and fine particles), and the active ingredient is volatilized in the air by the action of the smoke and heat. Therefore, the active ingredient can be spread throughout the space in a short time, and pests can be controlled.

  The soot agent is heated using a direct heating method in which a part of the soot agent is heated to burn the soot agent, or by using the heat of heat (hydration reaction heat) between the exothermic agent such as calcium oxide and water. An indirect heating method for heating the smoke agent is used. For example, a smoke composition containing a combustion base such as azodicarbonamide and an insecticidal component is heated by an indirect heating method using the heat of hydration reaction of calcium oxide, etc., and ejected by self-combustion of the combustion base Smoke devices that volatilize active ingredients in the space in a short time with smoke (gas and fine particles generated by thermal decomposition) have been proposed and put into practical use.

  As described above, since the smoke device uses combustion of the combustion base, a non-combustible container is used. As the nonflammable container, a metal can such as aluminum or tinplate is used. In recent years, TFS (Tin Free Steel), which is a steel sheet that does not use tin, has been used as an alternative to tinplate. Thus, by making a container metal, it can prevent that a container ignites in smoke or deform | transforms by heating.

By the way, the heat generated by the exothermic agent is high temperature. In particular, the temperature of the hydration reaction heat when calcium oxide is used as the exothermic agent is about 250 to about 400 ° C. And when a metal container is adopted, since the thermal conductivity is high, the outer peripheral surface of the container is also about 250 to about 400 ° C. Thus, when the outer peripheral surface of the container is heated to a high temperature, an odor that burns the container is generated. Further, since the smoke agent is also heated to about 250 to about 400 ° C., a smell that burns the smoke agent is also generated. The smell of burning containers and smoke agents (burning odor) causes discomfort.
Then, in order to reduce a burning smell, the smoke agent which mix | blended the fragrance | flavor is proposed (for example, refer patent documents 1-4).

Japanese Patent Laid-Open No. 63-26056 JP-A-3-255005 JP-A-10-287508 JP 11-349405 A

However, even if a fragrance is blended with a smoke agent as described in Patent Documents 1 to 4, it is difficult to sufficiently reduce the burning odor. Moreover, the fragrance of the fragrance could not be fully felt.
Increasing the amount of fragrance is thought to improve the fragrance of the fragrance and reduce evaporation of the fragrance, but increasing the amount of fragrance will disperse the fragrance uniformly in the combustion base and active ingredients. It becomes difficult. Moreover, the fragrance | flavor which is easy to volatilize is easy to lose when drying a smoke agent.

  The present invention has been made in view of the above circumstances, and provides a smoke method, a smoke device unit, and a smoke device that can reduce the burning odor during smoke and can sufficiently sense the scent of the fragrance. With the goal.

  As a result of intensive studies, the present inventors have focused on water that reacts with a heat generating agent. And it discovered that the fragrance of a fragrance | flavor was improved by reacting water and a heat generating agent in presence of a fragrance | flavor, and burnt odor could be fully reduced. In addition, according to this method, since it is not necessary to add a fragrance to the smoke agent, there is no risk of the fragrance evaporating or decomposing during the production or storage of the smoke agent, and the fragrance of the fragrance is sufficient when smoking. The present invention has been completed based on the idea that it can be felt.

That is, this invention has the following aspects.

"Smoke method"
The soot method of the present invention is an indirect heating method in which the soot agent is heated using the reaction heat between the exothermic agent and water, and the exothermic agent and water are reacted in the presence of a fragrance.
By reacting the exothermic agent and water in the presence of the fragrance, the fragrance of the fragrance is improved when smoked, and the burnt odor can be sufficiently reduced. In addition, since the burning method of the present invention can sufficiently reduce the burning odor without adding a fragrance to the smoke agent, the fragrance may evaporate or decompose during the production or storage of the smoke agent. The scent of the fragrance can be fully felt when smoking.

  As a method of reacting the exothermic agent and water in the presence of the fragrance, a method of reacting water containing the fragrance (fragrance-containing water) and the exothermic agent (method 1); The method (Method 2) etc. which attaches a fragrance | flavor beforehand to the part (The predetermined inner surface of the below-mentioned outer container, or the bottom part of an inner container) which contacts the water of the smoke device used for 1 is mentioned. In the case of the method 2, water and a fragrance are mixed by adding water into an outer container to form a fragrance-containing water, and the fragrance-containing water and a heat generating agent react.

Among the methods described above, Method 1 is preferable because it is easy to adjust the concentration of the fragrance in the fragrance-containing water. Moreover, if it is the method 1, evaporation of a fragrance | flavor can also be suppressed more effectively.
In addition, in the case of the method 2, there is a possibility that the perfume adhering to a predetermined part of the smoke device evaporates before the smoke device is used. In such a case, the evaporation of the fragrance can be reduced by preliminarily attaching an excessive fragrance to a predetermined portion of the smoke smoking device. At this time, since excess fragrance is not blended with the smoke agent, problems (uniform dispersion and leakage during drying) that occur when the amount of the fragrance blended in the smoke agent is increased as described above. Absent.

Next, examples of various materials used in the smoke method of the present invention will be described.

As the soot device, an indirect heating type soot device generally used for controlling sanitary pests, molds, bacteria, and the like can be used. A commercially available smoke device may be used.
Here, an example of the smoke device will be described with reference to FIG.

<Smoke device>
The smoke device 1 shown in FIG. 1 includes a bottomed cylindrical outer container 10 and a bottomed cylindrical inner container 20 provided in the outer container 10 and having a bottom portion 24 having water permeability.

The outer container 10 is roughly composed of a cylindrical peripheral wall portion 12 and a bottom portion 14.
Four rectangular parallelepiped projections 15 are arranged at 90 ° intervals on the inner bottom surface 14a of the bottom portion 14.
The size of the outer container 10 is determined according to the amount of the smoke agent to be used, the size of the inner container 20 and the like. If the floor area of the space to be processed is home use of about 6.5 to 30 m ² , for example, the height of the outer container 10 is 40 to 120 mm, and the inner diameter of the outer container 10 is 55 to 100 mm.

  The material of the outer container 10 only needs to have at least water resistance, and examples thereof include plastic and paper. The thickness of the outer container 10 can be determined in consideration of strength and the like, for example, 0.5 to 10 mm.

The inner container 20 is generally configured by a cylindrical side wall portion 22 and a bottom portion 24.
The outer peripheral surface 22 b of the inner container 20 is separated from the inner peripheral surface 12 a of the outer container 10.
In the inner container 20, a heating unit 30 and a heated unit 40 are provided via a heat transfer unit 50. The heating unit 30 is formed by filling the inner container 20 with a heat generating agent.

The heat transfer unit 50 is a bottomed cylindrical member, and is provided in the inner container 20 so that a part thereof is buried in the heating unit 30. The heat transfer section 50 is filled with a smoke agent to form a heated section 40.
The upper end part 50c of the heat transfer part 50 and the upper end part 22c of the side wall part 22 are connected by a connecting member 26, and the upper container 20 and the heat transfer part 50 are closed by the connecting member 26 on the upper end face 20e. Further, the connecting member 26 is provided with a vent hole 26a that serves as a hole for a vapor generated when the heat generating agent reacts with water.
A lid 60 is provided in the vicinity of the upper end surface 50 e of the heat transfer unit 50.

  The heat transfer unit 50 is smaller than the inner container 20, and is provided so that its upper end surface 50 e is flush with the upper end surface 20 e of the inner container 20. That is, the inner peripheral surface 22 a of the inner container 20 is separated from the outer peripheral surface 50 b of the heat transfer unit 50, and the bottom 24 of the inner container 20 is separated from the bottom 54 of the heat transfer unit 50. A heating agent is filled between the inner container 20 and the heat transfer unit 50. The distance between the bottom 24 of the inner container 20 and the bottom 54 in the heat transfer section 50 is preferably 10 to 18 mm, and more preferably 12 to 14 mm.

The size of the inner container 20 is determined according to the amount of smoke agent used. If the floor area of the space to be processed is home use of about 6.5 to 30 m ² , for example, the height of the inner container 20 is 30 to 110 mm, and the outer diameter of the inner container 20 is 45 to 90 mm.

  In the smoke device 1, the outer peripheral surface 22b and the inner peripheral surface 12a are preferably separated from each other by 7 mm or more. If the distance between the two is less than 7 mm, the outer container 10 may become too hot when smoked. When the distance between the outer peripheral surface 22b and the inner peripheral surface 12a is 15 mm or less, the spray output of the smoke agent from the inner container 20 by heating becomes stronger, and the effect of the present invention can be more easily obtained.

The bottom portion 24 of the inner container 20 in this example includes a water permeable bottom plate 241 in which a water permeable material 241c is placed on a plate 241b having a water passage hole 241a. The water permeable material 241c is preferably placed so as to cover substantially the entire surface of the plate 241b. In particular, the bottom 24 is preferably a water permeable bottom plate formed by caulking the water permeable material 241c to the plate 241b. If the bottom 24 is a water-permeable bottom plate 241 formed by caulking the water-permeable material 241c to the plate 241b, the position of the water-permeable material 241c can be prevented from being shifted or rolled up on the bottom 24. Therefore, it is difficult for the time to start soot to vary, and the packaging process is easy to mechanize.
The method for caulking and adhering the water-permeable material 241c to the plate 241b is not particularly limited, and examples thereof include a method described in JP-A-2001-247407. For example, in a metal circular plate having water passage holes for water passage, several locations (preferably 4 or more, more preferably 6-8 locations), preferably outside the water passage holes for water passage, are provided. A small hole is drilled at a position close to the circumference, more preferably at a symmetric position, on the back side of the metal plate when drilling the hole, and preferably two or more protrusions per hole. Then, a water-permeable material is placed on the surface on which the protrusions are projected and pressed. If it does so, protrusion will fall sideways and it will be crushed and a water-permeable material will adhere to a metal plate.

The plate 241b is preferably a metal plate such as tinplate, steel plate, aluminum.
As the water-permeable material 241c, a highly water-permeable nonwoven fabric, filter paper, or the like is preferable. For example, a synthetic fiber such as polyolefin (polyethylene, polypropylene, etc.), nylon, or polyester, or a nonwoven fabric made of these synthetic fibers and cotton, rayon, or the like. Non-woven fabric or filter paper made of glass fiber; cellulose-based filter paper and the like. Among these, a nonwoven fabric containing a large amount of rayon is preferable because it has high water permeability and is stronger than cellulosic filter paper.

  As the material of the side wall portion 22, a material having heat resistance that does not cause deformation due to heat generated in the heating unit 30 is used, and examples thereof include metals, ceramics, paper, and the like. The thicknesses of the side wall portion 22 and the bottom portion 24 can be determined in consideration of required strength, heat resistance, and the like. For example, the thickness of the side wall portion 22 is 0.1 to 5 mm, and the thickness of the bottom portion 24 is 0. 1 to 5 mm.

The heat transfer unit 50 functions as a container filled with a smoke agent and has a function of transmitting heat energy generated in the heating unit 30 to the heated unit 40.
The material of the heat transfer part 50 should just have heat conductivity, and a metal is preferable. The thickness of the heat transfer unit 50 can be determined in consideration of heat transfer properties and the like, for example, 0.1 to 5 mm.

The size of the heat transfer unit 50 is determined according to the amount of smoke. If the floor area of the space to be processed is for home use of about 6.5 to 30 m ² , for example, the height of the members constituting the heat transfer unit 50 (the distance between the bottom 54 and the upper end surface 50e) is 10 to 10. The outer diameter of the member is 80 to 85 mm.

The lid 60 has a hole through which the smoke agent vapor passes, and examples thereof include a mesh, a punching metal, and a lattice frame.
As the material of the lid 60, a material having heat resistance that does not cause deformation due to high-temperature steam generated from the heated portion 40 is used, and examples thereof include metals, ceramics, and paper.

<Perfume-containing water>
The perfume-containing water is put in the outer container of the smoke device and reacts with the heat generating agent.
Examples of the fragrance-containing water include the fragrance-containing water exemplified above in the description of the smoke method.
The perfume-containing water is stored in a storage container. The shape and material of the storage container are not particularly limited as long as they can store liquid and can be stored and transported. Examples of the shape of the storage container include a bag shape, a bottle shape, a cup shape, and a tray shape. Examples of the material of the container include resin and glass.

<How to smoke>
A smoke method using the smoke device unit of the present invention will be described.
First, perfume-containing water is put into the outer container 10 of the smoke device 1 shown in FIG. Next, the outer container 10 containing the fragrance-containing water is placed in the target space, and the inner container 20 is disposed on the protrusion 15 of the outer container 10 so that the bottom 24 of the inner container 20 is immersed in water. . When the inner container 20 is disposed, the water that has entered the inner container 20 from the bottom 24 undergoes a hydration reaction with the exothermic agent in the heating unit 30 to generate heat.
The amount of the fragrance-containing water to be put in the outer container 10 should be at least as much as the bottom 24 of the inner container 20 is immersed in water, but is preferably as small as possible from the viewpoint of increasing the heat generation efficiency.

  The heating temperature of the smoke agent is preferably 150 to 450 ° C, more preferably 170 to 400 ° C, and further preferably 190 to 400 ° C. By heating at 150 ° C. or higher, the generated combustion base vapor can be ejected in the form of smoke, and the active ingredient can be diffused throughout the target space in a short time. Within the range of the heating temperature, the higher the heating temperature, the shorter the time required for the active ingredient to diffuse throughout the target space, and the wider the diffusion range. When heating temperature exceeds 450 degreeC, an active ingredient will thermally decompose and there exists a possibility that the quantity volatilized in an effective state (undecomposed state) may reduce (volatilization efficiency falls).

  Moreover, what is necessary is just to set suitably the heating temperature of a smoke agent, a heating rate, and holding | maintenance time according to the kind of active ingredient. When using calcium oxide as a heat generating agent, it can be controlled by selecting the ratio of calcium oxide and flavor-containing water, the amount of calcium oxide used, the product grade of calcium oxide, and the particle size of calcium oxide. The ratio between the calcium oxide and the fragrance-containing water may be appropriately determined in consideration of the color density of the generated smoke, the amount of smoke generated, the duration of smoke generation, the amount of volatilization of the active ingredient, and the like. It can also be controlled by the capacity or material of the members constituting the heat transfer section 50 filled with the smoke agent.

And the heat | fever which the fragrance | flavor containing water which permeated from the bottom part 24 generate | occur | produced by the hydration reaction with the heat generating agent in the heating part 30 is transmitted to the smoke agent through the peripheral wall and bottom wall of the heat transfer part 50, The temperature rises and evaporates. That is, the combustion base vapor is generated, and the active component diffuses through the hole of the lid 60 together with the generated vapor.
On the other hand, the water vapor generated by the hydration reaction escapes from the vent hole 26a. At this time, the perfume in the perfume-containing water also volatilizes and passes through the vent hole 26a together with the water vapor and is released into the target space. The released fragrance can reduce the burning odor of the smoke agent and the container, and the fragrance of the fragrance can be felt.
