Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid-absorbing core material used in a heating and evaporating apparatus for evaporating an effective component of a fragrance by heating. The present invention relates to a liquid-absorbent core material which enables the above-mentioned process, and a method for controlling volatilization of a fragrance using the same.

[0002]

2. Description of the Related Art Conventionally, a wicking-type heating and evaporating apparatus for a fragrance using a liquid-absorbing core material is prepared by putting a fragrance in which a fragrance is dissolved in a solvent into a container provided in the apparatus and absorbing the fragrance into the fragrance. The core material is immersed to suck up the fragrance, and the tip of the core material is heated by a ring-shaped heater arranged around the tip of the core material to evaporate the effective component (fragrance) of the fragrance. It is intended to be. Various types of liquid absorbent core materials are known as the liquid absorbent core material used in the wicking-type heat evaporation apparatus, but the shape of the conventional liquid absorbent core material is generally cylindrical. Moreover, the upper ends of the liquid-absorbing cores were flat (hereinafter, referred to as "flat cores"). This shape comes from a manufacturing process of a core material in which a long linear body is cut into a predetermined length. In addition, the method of adjusting the amount of fragrance evaporated in the apparatus is a method in which the cylindrical liquid-absorbing core material is moved up and down at the center of a ring-shaped heater.

[0003] Therefore, the upper end of the liquid-absorbing core is located between the upper and lower ends of the ring-shaped heater, and the area of the portion where the tip of the liquid-absorbing core overlaps the heater changes as the liquid-absorbing core is raised and lowered. During this state, the heated area of the absorbent core material changes, and the amount of fragrance evaporated can be changed according to the change in the heated area. However, since the diameter of the liquid absorbent core is the same even when the liquid absorbent core is raised so that the upper end of the liquid absorbent core is raised above the upper surface of the heater, the diameter of the liquid absorbent core is the same. Since the amount of heat applied to the core material did not differ much, it was not possible to control the substantial amount of fragrance evaporated. Also, when the flat core material is evaporated and the concentration of the active ingredient of the fragrance to be evaporated is high, the area where the area of the liquid absorbing core material overlaps with the heater changes in the area where the area changes. Even with a slight change, the change in the amount of the active ingredient of the fragrance became large, so that the amount of transpiration could not be fine-tuned, so that it could not withstand actual use.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned drawbacks of the prior art and to provide a technique capable of well controlling the substantial evaporation of the active ingredient of a fragrance, and to provide a high concentration of the active ingredient at a high concentration. Even when a certain fragrance is used, it is possible to finely control the substantial evaporation amount of the active ingredient.

Means for Solving the Problems As a result of earnest research, the present inventor has found that by changing the shape of the tip of a liquid absorbing core material used in a heating suction type heating and evaporating apparatus, fragrance from the liquid absorbing core material can be improved. The present inventors have found a method which allows a substantial fine adjustment of the amount of the agent transpiration, and reached the present invention. That is, the present invention has solved the above problem by the following means. (1) In the absorbent core material for use in the fragrance heating and evaporating apparatus, the tip arranged near the heater provided in the heating and evaporating apparatus has a shape in which the surface area of the absorbent core material becomes smaller toward the tip. An absorbent core material for heating and evaporating an air freshener, comprising: (2) The liquid absorbent core for fragrance heating and evaporation according to the above (1), wherein a tip portion of the liquid absorbent core has a conical shape. (3) In the method of volatilizing an fragrance using a fragrance heating and evaporating device having a liquid-absorbing core material, as a liquid-absorbing core material, a tip portion disposed in proximity to a heater provided in the heating and evaporating device includes: The use of an absorbent core material having a shape in which the surface area of the absorbent core material becomes smaller toward the tip, and adjusting the amount of fragrance evaporated by moving the heater or the absorbent core material up and down. Volatilization control method.

[0006] The shape of the tip of the liquid-absorbing core material used in the present invention can be various shapes such as a conical shape or a pyramid shape, but a conical shape is preferable. Further, if the cross section is made thinner toward the tip, the cross section may be a star shape instead of a circular shape. In short, the surface area decreases as it becomes the tip at the tip of the absorbent core material, and consequently the volatilization area decreases,
Furthermore, since the distance from the heater installed in the apparatus to the surface of the absorbent core material becomes longer due to thinning, the heating temperature of the fragrance present on the surface of the absorbent core material is also lower. Due to such an effect, the amount of the fragrance evaporated at the front end becomes smaller at the front end per unit length in the longitudinal direction of the absorbent core. The shape of the distal end portion of the liquid-absorbing core material used in the present invention is not particularly limited as long as a portion having a smaller surface area is provided so as to become the distal end. However, it is preferable to make the shape of the tip of the liquid-absorbing core material conical because processing is easy and the effect is great.

Since the liquid-absorbing core material of the present invention has the structure described in (1) or (2) above, it uses a ring-shaped heater having a conventional width in the fragrance heating and evaporating apparatus shown in FIG. By heating the tip portion of the absorbent core material, the evaporation amount of the fragrance can be adjusted in five or more stages. Furthermore, even when a high-concentration preparation is used, fine adjustment is possible.
