Electric liquid mosquito-repellent incense consists of mosquito repellent liquid (mainly pyrethroid) and electric heater. Its mosquito repellent principle is that when the electric heater is connected to the power supply, the PTCR element begins to heat, and then its temperature is kept within a certain range by virtue of its own temperature adjustment function. The heat generated by PTCR element is transferred to the volatile core of the liquid medicine through thermal radiation, so that the liquid medicine is sucked from the liquid medicine bottle to the upper end of the mandrel through the capillary action of the volatile core, and the volatilization speed is increased under the heating of the thermal radiation. When the insecticidal effective components in the space reach a certain concentration, it will play the role of repelling, paralyzing, knocking down and killing mosquitoes.

The inner wall temperature of the middle metal sleeve of the electrothermal liquid mosquito-repellent incense heating device is between 120- 130℃, and the temperature of the volatile core is between 90- 100℃.
