The present invention relates to a fuming composition comprising a wax impregnated with a fuming component and a heating /

The fumigation disinfection apparatus is currently used in many fields as an indoor disinfection apparatus and a vehicle disinfection apparatus. These fumigating devices generate high heat by the exothermic reaction of water and calcium oxide, and utilize the phenomenon that the generated high temperature fumigates and fumigates the fumigant. Since effective ingredients such as bactericides and antibacterial agents are evaporated into the air, they exhibit more effective sterilization and antibacterial effect in a closed room. Fumigated medicines work in all corners of the room and have the advantage of being able to eradicate fungi and insects that are out of reach of human hands.

Such a fumigation system includes a fumigant-type composition containing a pharmacological agent. Among these fumigant-type compositions, there is a technique of aluminum-wrapping a pharmaceutical powder (powder) in order to enhance the stability of the product. However, this technique requires a separate process for aluminum packaging, which is inconvenient for consumers.

In addition, there is a fuming composition prepared by impregnating an organic or inorganic powder with an incense and an oil. When such a fuming composition is applied to a direct heating fumen can, the impregnated fragrance is gradually volatilized and an oil film Which may cause a poor heat generation phenomenon, and this phenomenon is further increased at high temperature storage and long-term storage. There was a problem that the heat generation defect was further increased in the long-term stored product, and in the case of the heat generation defective product, the remaining amount was increased, resulting in the problem that the product was ineffective. Therefore, it is urgently required to improve the poor heat generation phenomenon caused by such oil film formation.

Numerous papers and patent documents are referenced and cited throughout this specification. The disclosures of the cited papers and patent documents are incorporated herein by reference in their entirety to better understand the state of the art to which the present invention pertains and the content of the present invention.

The present inventors have conducted studies to minimize the volatilization of fragrance during the production of the fumed cans so as to optimize the generation of the fragrance when using the fumed cans for heating, and also have found that when the impregnated fragrance is volatilized during long-term storage to form an oil film on the nonwoven fabric, A study was conducted to improve the heat generation failure of the can. As a result, the fumed composition was prepared by impregnating the fumed component into the wax melted by heating. The fuming time, the amount of foaming and the residual amount after completion of foaming were observed during the long-term storage of the manufactured fumigation composition, The present invention has been completed.

Accordingly, an object of the present invention is to provide a fuming composition.

Another object of the present invention is to provide a heating and vaporizing apparatus.
