Description

  The present invention relates to a smoke device.

  Smoke devices are widely used to control sanitary pests such as flies, mosquitoes and cockroaches, and pests such as microorganisms such as bacteria and fungi. The smoke device includes a smoke agent or a fumigant (hereinafter generally referred to as a smoke agent) and means for heating the smoke agent. Smoke agents are mainly composed of an exothermic base in which various combustion agents or foaming agents are mixed and a drug as an active ingredient. In such a smoke device, the exothermic base is combusted or decomposed by the heating means, the chemical is vaporized by the generated combustion heat or heat of decomposition, and is released and diffused into the air. Alternatively, the vaporized drug is released and diffused in the air within a short time by the action of gas or smoke particles generated by the decomposition of the pyrogenic base (hereinafter, the release and diffusion of the drug in the air is called volatilization. ).

As the smoke device, for example, a device including a lid 910 and a device main body 920 as in the smoke device 900 of FIG.
As shown in FIG. 10, the lid 910 is provided with a sliding plate 912 in the vicinity of the periphery.

The outer container 922 and the smoke storage container 930 are spaced apart from each other and their upper ends are connected by a connecting plate 924.
The middle lid 940 includes a substantially cylindrical middle lid wall portion 960, a support plate 970 provided in the middle lid wall portion 960, and a top plate 950 provided above the support plate 970. The top plate 950 has a top plate smoke hole 952 and a top plate through hole 954, and the support plate 970 has a support plate smoke hole 972 and a support plate through hole 974.
As shown in FIG. 11, an annular plate 956 is extended on the periphery of the top plate 950, and a flange portion 958 is erected on the periphery of the annular plate 956, and the top plate 950, the annular plate 956, and the flange The smoke permeable lid 951 is constituted by the portion 958. By attaching the smoke permeable lid 951 to the inner lid wall 960, the top plate 950 is provided in the inner lid wall 960.
The igniter 980 includes a substantially cylindrical igniter 986, an ignition part 982 provided at the upper end of the igniter 986, and a fixing part 984 that fixes the igniter 986 to the support plate 970. The lower end is inserted into the smoke agent 902.
The smoke device 900 is used by igniting the ignition part 982 by rubbing the ignition part 982 with a scraper 912. When the ignition unit 982 is ignited, heat is transmitted to the smoke agent 902 through the ignition material 986, and the smoke agent 902 is burned. When the smoke agent 902 burns, the chemical contained in the smoke agent 902 is volatilized.

 When rubbing the ignition portion 982 with the sliding plate 912, for example, the sliding plate 912 is positioned in the vicinity of the periphery of the top plate 950, and the lid 910 is moved toward the ignition portion 982 to excessively increase the ignition portion 982. When an appropriate pressure is applied, the ignition part 982 may fall off the igniter 980 and the igniter 980 may be lost. Alternatively, if the pressure of the sliding plate 912 to the ignition part 982 is too small, there is a problem that the ignition part 982 cannot be ignited.

 For these problems, it consists of a main body part into which the match head drug protrudes and a push button part that can be pushed into the main body part. The main body part has a match side drug layer facing the match head medicine. There has been proposed an igniter having a pressing protrusion that rubs the match side drug layer against the match head medicine when the push button part is pressed (see, for example, Patent Document 1).

The obtained mixture is granulated with a pre-extrusion or a lateral extrusion granulator. The granulated product may be further cut into a certain size using a cutter or the like and dried.

Next, the method for using the smoke device 1 of the present invention will be described by taking as an example the case where the smoke agent 2 contains an exothermic base that thermally decomposes by heating to generate heat and gas.
First, as shown in FIG. 4, the apparatus main body 20 is held with one hand, the lid 10 is held with the other hand, and the sliding plate 12 is positioned inside the ridgeline 92. Next, the lid body 10 is moved in the X direction, and the ignition portion 82 is rubbed with the sliding plate 12 to ignite the ignition portion 82. At this time, since the ignition portion 82 is surrounded by the raised portion 90, the user places the sliding plate 12 near the periphery of the top plate 50 (for example, on the annular plate 56) and moves the lid 10 in the X direction. Even when the lid 10 is moved, the lid 10 collides with the raised portion 90. For this reason, when the ignition part 82 is ignited, the place where the sliding plate 12 is positioned is regulated within the ridgeline 92, and the sliding plate 12 can be prevented from colliding with the ignition unit 82 due to excessive pressure.

When the ignition part 82 is ignited, the inside of the ignition material 86 is heated, and accordingly, heat is transmitted from the contact portion between the ignition material 86 and the smoke agent 2 to the smoke agent 2. When the arbitrary amount of heat propagates to the smoke agent 2, the smoke agent 2 burns. Thereafter, the smoke agent 2 continues to burn, and the combustion heat is transmitted to the smoke agent 2 as a whole.
When the smoke agent 2 reaches an arbitrary temperature, the chemical vaporizes and the exothermic base decomposes to generate gas. And the vaporized chemical | medical agent flows out from the top-plate smoke hole 52 with gas, and is spread | diffused in the air.

According to the present embodiment, the top plate is formed with a raised portion so as to surround the top plate through-hole, and the first side wall portion forms a stepped wall portion. It is possible to prevent excessive pressure from being applied to the ignition device and to prevent the ignition device from being lost.
In addition, according to the present embodiment, the smoke device capable of preventing the igniter from being lost can be obtained by an easy manufacturing method of forming the stepped wall portion on the top plate.
