Fan type chemical diffusing apparatus

Abstract

A fan type chemical diffusing apparatus includes an apparatus main body having an air inlet and an air outlet, a fan type blower disposed in the apparatus main body, and an active ingredient impregnated body or mass for containing an active ingredient. The fan type blower includes a fan casing, a motor, and a fan including a rotary disk and a plurality of blades fastened to a peripheral portion of the rotary disk and provided with a hollow space that is on an interior of the fan with respect to the blades. The fan type blower is operable to send air from the air inlet through the hollow space and out through the air outlet.

1 . A fan type debugging apparatus for repelling and expelling a noxious or harmful insect with an active ingredient containing as its principal component at least one chemical having a vapor pressure of not less than 1.0×10 −4  mmHg at a temperature of 30° C. and effective to act as an insecticide or acaricide or to control growth, or to hinder bloodsucking, biting or eating behavior, of the insect, or to repel the insect, or effective to prevent any other damage by the insect, the apparatus having an active ingredient impregnated body or mass adapted to retain and release by volatilization said active ingredient, and including a fan type blower powered to be driven by a motor, wherein: 
 said fan type blower is operable to iteratively run and halt alternately with a time period of halt from more than one time to not more than 9 times as long as a running time period, said time period of halt being also a time period in which a current or quantity of electricity not lost therein is more than a current or a quantity of electricity consumed in excess by said motor in said running time period.
