Abstract

PURPOSE:To enhance vaporizing performance of insecticidal ingredients and reduce decomposition of the insecticidal ingredients, by setting the heating temperature in the central part of a heat radiating plate and a heating temperature difference between the central part and the peripheral part within respective specific ranges. CONSTITUTION:An electric mosquito catcher constituted of a heating unit having a thermistor, having positive characteristics and sandwiched between a pair of electrode plates and a heat radiating plate for carrying a larger mat than the heating unit. The heating temperature in the central part of the heat radiating plate is kept at 140-165 deg.C and the difference between the central part and the peripheral part is set at <=15 deg.C by a method for inserting a metallic plate having excellent thermal conductivity between the heating unit and the heat radiating plate. This catcher is especially effective in the case of an insecticidal ingredient-containing mat, such as furamethrin or prallethrin, readily causing decomposition by heating at high temperature.

DETAILED DESCRIPTION OF THE INVENTION In heating and evaporating a mat containing an insecticidal component, the present invention provides a heating element in which a positive temperature coefficient thermistor is sandwiched between a pair of electrode plates, and a heat dissipating material for placing the mat that is larger than the heating element. An electric mosquito repellent consisting of a plate, in which the heating temperature at the center of the heat sink for placing the mat is in the range of 140-165°C, and the difference in heating temperature between the center and the peripheral area is 15°C or less. Concerning vessels.

Conventionally, heating elements in which a positive temperature coefficient thermistor is sandwiched between a pair of electrode plates have been used because there is almost no change in the heating element temperature due to voltage fluctuations, the temperature rises quickly, and there is little risk of overheating. Electric mosquito repellents have been widely used in which the central part of a heat sink for placing a mat, which is larger than the heating element, is brought into close contact with the upper surface of the heating element and fixed therein.

However, due to manufacturing and cost considerations, the heating element is designed to be smaller than the heat sink, and as a result, the difference in heating temperature between the center and the periphery of the heat sink reaches as much as 30 to 40 degrees Celsius, resulting in poor volatilization performance for insecticidal ingredients. Moreover, the temperature at the center must be set at 170° C. or higher, and the insecticidal component in the mat that comes into contact with the high-temperature heating section inevitably decomposes.

As a result of intensive research into means for reducing the decomposition of the insecticidal component and effectively heating and evaporating the insecticidal component, the present inventors set the heating temperature at the center of the heat sink in the range of 140 to 165°C, and The present invention has been completed by discovering that the object can be achieved when the mat is applied to an electric mosquito repellent set so that the difference in heating temperature between the center and the periphery is 15° C. or less.

By the way, in Japanese Patent Publication No. 50-39013, the temperature distribution is adjusted so that the heating temperature received by the insecticidal ingredient-containing mat has a temperature difference of 20°C or more, so that the insecticidal ingredient is volatilized at an early stage at the contact area, thereby increasing the initial insecticidal effect. However, there is no description of the decomposition of the insecticidal component in the high-temperature contact area.
4M provides a completely new and extremely useful electric mosquito repellent that aims not only to volatilize insecticidal ingredients but also to reduce decomposition of insecticidal ingredients.
