Method for vaporizing insecticide products has rechargeable battery driven fan discharging over PTC resistor in mains voltage supply line

摘要

A volatile insecticide contained within a carrier medium is vaporized by a fan (5) driven air stream over a PTC resistor (1) in the voltage supply to a rectifier unit (2) and rechargeable battery (3). The charging voltage is therefore related to the temperature of the air stream.
