摘要:
A chemical cartridge for a blower-type chemical diffusing apparatus includes a chemical-impregnated body including an air-permeable and liquid-absorptive sheet impregnated with a chemical, and a retainer receptacle for containing the chemical-impregnated body. The retainer receptacle includes a liquid pool recess formed at a central area thereof such that liquid chemical stored in the liquid pool recess is permeable towards a peripheral area of the sheet.

A blower type chemical diffusing apparatus is disclosed that is small in thickness, simple in structure and reduced in cost structurally to allow the chemical and battery to be exchanged readily and to facilitate electrically connecting battery to the motor in the blower. The apparatus casing comprises a first and a second side casing counterpart hinged together to allow its opening and closure, a blower with a motor and fan mounted in the first casing body, a chemical cartridge disposed between the blower and the second casing body and containing a chemical impregnated body that comprises a carrier in the form of a sheet impregnated with chemical. Also provided in the first casing body is a battery accommodating recess in which dry cells may removably be accepted to drive the motor and thereby to rotate the fan. Air is thus forced to flow through the chemical cartridge. A chemical cartridge is also provided that is thinned, capable of sustaining its given shape, free from contaminating the hand and not wasting chemical. It uses a chemical impregnated body in the form of an air permeable and liquid absorptive sheet impregnated with chemical, which is loaded in a receptacle having a base and a cover member adapted to hold the sheet body between them. The retainer receptacle has a central, a peripheral and intermediate support sections formed to provide recesses between them and spaced between them and the lower face of the chemical impregnated body while the cover member has a central, peripheral and intermediate hold sections formed with airflow holes to allow air to flow into those spaces, there by permitting those portions of impregnated chemical which are present between the hold and support sections to be entrained in air passing through the spaces and emanating into the atmosphere. A chemical impregnated body having a honeycomb structure is also provided to ease the user to refill the cartridge used out. An air permeable and liquid absorptive sheet body is disposed adjacent to a honeycomb body and in intimate contact with one of its open side faces and the bodies are impregnated with chemical. When the cartridge is depleted of its chemical, liquid chemical is supplied into the sheet body and allowed to permeate it over its entire area and then the honeycomb body over its entire area.
摘要:
An insecticidal composition for electric fumigator consisting essentially of:(A) an insecticidally effective amount of a preparation comprising 2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl-chrysanthemate and a synergist, wherein the weight ratio of said synergist to said chrysanthemate ranges from 1/2 to 8, and(B) a porous mat suitable for use on an insecticidal mat, said porous mat being impregnated with said preparation. This composition has both a lower content of an insecticidal active ingredient than ever and the capability of exhibiting a sufficient insecticidal activity over a long period of time.

In a method for knock down of injurious insects or for freeing a particular environment therefrom by heating fumigation comprising dipping a part of a porous absorptive wick in an insecticidal solution to allow it to absorb the solution and indirectly heating said wick around the top to fumigate the absorbed insecticidal solution, a method for knock down of injurious insects or for freeing a particular environment therefrom, which comprises exposing the insects to the vapor, characterized in that a C.sub.12 -C.sub.18 aliphatic saturated hydrocarbon solution containing as an active ingredient 2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl chrysanthemate is used as said insecticidal solution, a porous absorptive wick prepared by caking a powdery inorganic substance with a binding agent is used as said porous absorptive wick, and besides that said absorptive wick is indirectly heated around the top to a temperature in a range of from 105.degree. to 130.degree. C.

A blower type chemical diffusing apparatus is disclosed which can be of service for an extended period of time and does not give rise to refuse disposal problems. The blower type chemical diffusing apparatus of the invention has an air blower, a chemical retainer and a fuel cell included in the apparatus body whereby powering the air blower to drive it with the fuel cell causes chemical from the chemical retainer to be emitted into an environmental atmosphere.
