JP-A-7-322798

  The above-described chemical heating transpiration apparatus 50 prevents the careless contact with the high temperature part by making the transpiration hole 55 small enough for human fingers or the like to enter. Inevitably became smaller. For this reason, a phenomenon occurs in which a part of the medicine that evaporates upward from the medicine-containing body 51 comes into contact with the inner surface of the cover body 54 to form liquid droplets, resulting in a decrease in evaporation efficiency, discoloration / deterioration of the cover body 54, Had a problem.

  Accordingly, an object of the present invention is to provide a chemical transpiration apparatus capable of increasing the transpiration efficiency by suppressing the transpiration of the transpirational drug.

  The object of the present invention is a drug transpiration apparatus for heating a carrier impregnated with a drug to evaporate the drug, the apparatus main body having a heating element, a protective cover attached to the apparatus main body, and the heat generation A holding means for holding the carrier between a body and the protective cover, the holding means standingly holding the carrier in a use state, and a space portion between the carrier and the protective cover The space portion is achieved by a chemical evaporation device formed so that at least the upper portion communicates with the outside.

  In this chemical evaporation apparatus, it is preferable that the space portion is formed so that a distance between the carrier and the protective cover is 3 mm or more.

  The protective cover may have an extending portion that extends upward from the carrier when in use. In this case, it is preferable that the extending portion is formed so as to project toward the carrier side within a range not exceeding a position directly above the surface of the carrier.

  Moreover, it is preferable that the holding means holds the carrier so that the entire back surface of the carrier is in contact with the heat generation surface of the heat generator.

  Moreover, it is preferable that the said apparatus main body has a power plug in the surface on the opposite side to the surface where the said support body is hold | maintained.

  According to the chemical transpiration apparatus of the present invention, it is possible to suppress the formation of droplets of the transpirated chemical and increase the transpiration efficiency.

  Hereinafter, actual forms of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view showing a schematic configuration of a chemical transpiration apparatus according to an embodiment of the present invention in a partial cross section, and FIG. 2 is a plan view thereof. As shown in FIGS. 1 and 2, the chemical evaporation apparatus 1 includes an apparatus main body 10 and a protective cover 20 attached to the apparatus main body 10.

  The apparatus main body 10 is formed in a casing shape, and a step portion 11 is formed so as to be depressed in the center of the upper front surface. The step portion 11 has a planar heating element made of an electric heater such as a PTC heater. 12 is provided. The heat generating body 12 is configured such that the back side is fixed to the step portion 11 so that the heat generating surface 12a is located on the front side, and can be heated by energization via the power plug 13 provided on the rear surface of the apparatus body 10. Yes. The heating element temperature can be appropriately selected between 40 and 170 ° C., and when used as a fragrance, it is preferably 50 to 120 ° C., more preferably 60 to 90 ° C. When used as an insecticide, it is preferably 100 to 150 ° C, more preferably 120 to 140 ° C.

  A mounting portion 15 to which a flat carrier 14 impregnated with a drug is detachably attached is formed in front of the heating element 12 in the step portion 11. The mounting portion 15 inserts the carrier 14 from above as shown by an arrow and slides the carrier 14 along both side surfaces 11a of the step portion 11 so that the lower end portion of the carrier 14 contacts the lower surface 11b of the step portion 11. As a result, the carrier 14 is held in proximity to the heating surface 12a of the heating element 12. In a state where the carrier 14 is held by the mounting portion 15, it is preferable that the upper end of the carrier 14 is slightly lower than the upper end of the protective cover 20. The surface area of the carrier 14 (the area on the back surface facing the heating element 12) is preferably about the same as or slightly smaller than the area of the heating surface 12 a of the heating element 12.

  Examples of the drug carrier 14 include an adhesive and / or a sintered body and / or a tablet with an inorganic and / or organic powder as a main component, a paper and / or non-woven fabric with a pulp as a main component, a non-woven fabric with a plastic as a main component, and It can be selected from at least one of woven fabrics and other non-woven fabrics and / or woven fabrics mainly composed of animal and plant-derived substances, plastic-based foams, plastic wrought bodies, dried plant bodies, and gel bodies. In addition, liquid various chemicals such as bactericides, fragrances, and deodorants are appropriately impregnated and retained. Two or more kinds of drug carriers 14 can be used. In this case, each may be mixed, or may be layered and overlapped.

  Various chemicals are not particularly limited. For example, as a fragrance for a fragrance, sandalwood oil, cedarwood oil, pine oil, cypress oil, benzoic oil, etc. And / or natural and / or synthetic fragrances containing these components are preferred. These fragrance compositions have low room temperature volatility, and once a drug has been dropped, it accumulates without volatilization thereafter. Although there is a risk of eroding the material and the like, this problem can be effectively solved according to the chemical evaporation apparatus of this embodiment, as will be described later. In addition, an antioxidant, a pH adjuster, a colorant, a surfactant, an ultraviolet absorber, and the like can be appropriately added to the drug impregnated in the drug carrier.

  The protective cover 20 is made of a flat plate-like member, and is attached to the lower portion of the apparatus main body 10 via a rotation shaft 21 so as to face the front surface of the apparatus main body 10 with a space therebetween, and is rotatable in the direction indicated by the arrow. It is configured. The size of the protective cover 20 is substantially the same as that of the front surface of the apparatus main body 10, and two pressing protrusions 22 and 22 are provided at positions on the inner surface side corresponding to the carrier 14 mounted on the mounting portion 15. Yes. The pressing protrusions 22, 22 are in contact with the surface of the carrier 14 with the protective cover 20 closed, and the back surface of the carrier 14 is brought into close contact with the entire heat generating surface 12 a of the heat generating member 12. As a result, the carrier 14 is held in a state in which the front surface side is substantially flush with the front surface of the apparatus main body 10 and the space S is formed between the carrier 14 and the protective cover 20. The number of the pressing protrusions 22, 22 may be single, or three or more.

  Next, the operation of the chemical transpiration apparatus 1 having the above configuration will be described. The chemical evaporation apparatus 1 of the present embodiment attaches the carrier 14 to the mounting portion 15 and closes the protective cover 20, and then, as shown in FIG. 3, the outlet 41 installed on the wall surface 40 such as a home or office The power plug 13 can be inserted and used. The carrier 14 is held upright by the mounting portion 15 and the pressing protrusion 22, and is heated by energizing the heating element 12.

  In the present embodiment, since the entire back surface of the carrier 14 is in contact with the heat generating surface 12a of the heating element 12 by the pressing of the supporting body 14 by the pressing protrusions 22, the carrier 14 is heated by the heating element 12. Power saving is achieved by increasing the heating efficiency.

  When the carrier 14 is heated, the drug impregnated in the carrier 14 evaporates into the space S formed between the carrier 14 and the protective cover 20 and rises together with the heated air. It diffuses outside through the upper gap between the body 14 and the protective cover 20. Thus, since the chemical evaporation apparatus 1 of this embodiment holds the carrier 14 in an upright state and forms the space S between the carrier 14 and the protective cover 20, the protective cover 20 is In addition, it is possible to effectively prevent the user's finger or the like from coming into contact with a high temperature part such as the heating element 12 or the carrier 14, and to avoid collision with the upward flow of the medicine. As a result, the formation of droplets of the medicine on the inner surface of the protective cover 20 can be suppressed, and the transpiration efficiency can be improved and discoloration / deterioration of the protective cover 20 can be prevented.

  The space S formed between the carrier 14 and the protective cover 20 needs to be formed so that at least the upper part communicates with the outside. More preferably, the space S is formed between the carrier 14 and the protective cover 20. It is preferable to configure the drug transpiration apparatus 1 so that there is no obstacle that may collide with the upward flow of the drug in the upper gap. On the other hand, both or both sides and the lower portion of the space portion S may be partially or entirely blocked as long as the outside air is introduced into the space portion S with the upward flow of the medicine. When the entire sides and the lower part of the space S are closed, for example, a large number of small holes are formed in the lower part of the protective cover 20, so that outside air can be introduced into the space S.

  If the gap width “a” between the carrier 14 and the protective cover 20 in the space S shown in FIG. 3 is too small, the liquid evaporated from the carrier 14 collides with the inner surface of the protective cover 20 before the liquid evaporates. May cause droplets. According to the experimental results described below, the gap width a is preferably 3 mm or more in order to effectively prevent the liquid droplets of the medicine on the inner surface of the cover 20. On the other hand, if the gap width a is too large, a finger may enter between the carrier 14 and the protective cover 20. Therefore, in the configuration of the present embodiment, the gap width a is preferably 5 mm or less. .

  In the chemical vaporization device 1 of the present embodiment, the power plug 13 is provided on the surface of the device main body 10 opposite to the surface on which the carrier 14 is held, so that the chemical is vaporized at a position separated from the wall surface 40. It is possible to prevent the medicine from adhering to the wall surface 40 and forming droplets. However, even in the configuration of the present embodiment, if the overhang distance b from the wall surface 40 to the front surface of the carrier 14 is too small in the use state shown in FIG. There is a risk of becoming. According to the experimental results described later, it is preferable that the overhang distance b is 17.5 mm or more in order to effectively prevent the liquid droplets on the wall surface 40. On the other hand, if the overhanging distance b is too large, it tends to be a hindrance in use.

  As mentioned above, although one Embodiment of this invention was explained in full detail, the specific aspect of this invention is not limited to the said embodiment. For example, in the present embodiment, the power plug 13 is inserted into the outlet 41 installed on the wall surface 40 for use, thereby saving space during use. It is also possible to provide a support base or the like and place it on a floor surface or a table so that the heating element 12 is powered from a battery or the like attached to the apparatus main body 10.

  Moreover, in this embodiment, although the heat generating body 12 and the support body 14 are all formed in a flat plate shape, they can have various shapes such as a corrugated plate shape, a disc shape, and a ring shape.

  Further, in the present embodiment, the holding means for holding the carrier 14 in an upright state is constituted by the mounting portion 15 and the pressing protrusion 22, but the carrier 14 is not necessarily required to be in close contact with the heating element 12. Alternatively, the holding means can be configured only from the mounting portion 15 without providing the pressing protrusion 22.

  The specific configuration of the holding means for holding the carrier 14 can be variously modified as long as the holding can be reliably performed. For example, as shown in FIG. 4, holding rods 101, 101 extending forward from a heating element 12 installed on the front surface of the apparatus main body 10 are provided, and the holding rods 101, 101 are inserted into insertion holes 141, 141 formed in the carrier 14. The support 14 can be disposed in the vicinity of the heating element 12. In this case, the support 14 can be brought into close contact with the heating element 12 by fastening the nut from the front side of the support 14 using the holding rods 101 and 101 as bolts. Alternatively, as shown in FIG. 5, an L-shaped holding metal fitting 102 projecting forward from below the heating element 12 is provided, and the lower end portion of the carrier 14 is placed between the tip of the holding metal fitting 102 and the heating element 12. It can also be configured to be sandwiched.

  In various variations of the holding means, for example, as shown in FIG. 4, when a non-heating area A is formed between the upper edge of the heating surface 12 a of the heating element 12 and the upper edge of the front surface of the apparatus main body 10, If the height c becomes too large, the evaporated chemical may be formed into droplets in the non-heated area A. According to the experimental results to be described later, in order to effectively prevent droplets of the medicine in the non-heated area A, the height c of the non-heated area A is preferably 5 mm or less.

  Further, in the present embodiment, the carrier 14 is held upright so as to extend in the vertical direction in use, but the upright holding in this specification is not necessarily limited to holding in the vertical direction. As shown, the case where the carrier 14 is held in an inclined state is included. In this case, if the inclination angle θ of the carrier 14 with respect to the vertical direction becomes too large, the gap between the upper end of the carrier 14 and the protective cover 20 becomes large and a finger or the like can easily enter. 10 ° is preferable.

  The holding position of the carrier 14 by the holding means is preferably in the vicinity of the heating element 12. However, as long as the carrier 14 can be held between the heating element 12 and the protective cover 20, a configuration other than the above is used. Is also possible. For example, the carrier 14 is held on the inner surface side of the protective cover 20 (on the side facing the heating element 12) by appropriate means such as clamping or hanging, and the carrier 14 supported by the protective cover 20 is attached to the apparatus main body. It can also be configured to heat with ten heating elements 12.

  Further, as shown in FIG. 7, the protective cover 20 includes an extending portion 20 a that extends upward from the carrier 14, and the extending portion 20 a projects toward the carrier 14 side. You may comprise. In this case, even if the gap width of the space portion S is increased, it becomes more difficult for a finger or the like to enter between the carrier 14 and the protective cover 20, so that it is easy to secure a sufficient space in the space portion S. However, if the tip of the extended portion 20a protrudes beyond the position directly above the surface of the carrier 14 (the position indicated by the broken line in FIG. 7), the vaporized drug adheres to the inner surface of the excess portion and drops. Therefore, it is preferable that the extending portion 20a is configured to project in a range not exceeding the position directly above the surface of the carrier 14. The overhang of the extending portion 20a may be inclined as in the present embodiment, or the tip portion may be bent in the horizontal direction. Similarly, extending portions that protrude toward the carrier 14 may be provided on both side surfaces of the protective cover 20.

  The protective cover 20 only needs to be attachable to the apparatus main body 10. For example, the protective cover 20 is configured to be detachably attached to the apparatus main body 10 instead of being rotatable as in the present embodiment. May be. Further, the protective cover 20 may be fixed to the apparatus main body 10 as long as the carrier 14 can be held upright.

  Hereinafter, the present invention will be described in more detail based on examples. However, the present invention is not limited to the following examples.
