Abstract:
1. A blower type insect pest control apparatus including: an apparatus casing body having an air inlet port and a first and a second air discharge port, a chemical receptacle, and a fan and a motor in the apparatus casing body, the chemical receptacle retaining a chemical impregnated body impregnated with an insect pest control component, whereby rotating the fan by the motor draws air through the air inlet port and strikes the drawn air on the chemical impregnated body in the chemical receptacle, thereby causing the air to entrain the insect pest control component therein from the chemical impregnated body and to emanate and diffuse into an environmental atmosphere; wherein said first and second air discharge ports each comprise a hole having a radial length and inclined to a circumferential direction in which said fan rotates whereby when the apparatus is used with the apparatus casing body worn on a user, air is discharged upwards through said first air discharge port and downwards through said second air discharge port; and wherein an inner inlet of each of the first and second air discharge ports opposed to the fan communicates with a corresponding outer outlet of each of the first and second air discharge ports which opens to an outer face of the apparatus casing body; and wherein the hole of each of the first and second air discharge ports has an upstream side guide face connecting an upstream side inlet hole edge of the inner inlet and an upstream side outlet hole edge of the outer outlet continuously to each other and a downstream side guide face connecting a downstream side inlet hole edge of the inner inlet and a downstream side outlet hole edge of the outer outlet continuously to each other, said upstream side and downstream side guide faces of the first and second air discharge ports each being inclined to a circumferential direction in which the fan rotates, and said upstream side guide face being arcuate.
