Disposable insecticide canister for an electric fogger

Electric fogger for dispensing insecticides

A disposable canister for use in an electric fogger includes a container to hold a fog-producing material which is constructed of a material capable of transferring heat from a heat source to the fog-producing material, an insert secured in the container to close the container and having a dome with a discharge port to allow the release of a fog, and a cap secured to the container and having an opening which overlies the discharge port of the insert to allow the release of a fog and one or more lugs which serve to activate an electric fogger when placed in the housing of the electric fogger. The cap of the disposable canister also includes outwardly extending rims which seat on the housing of the electric fogger and in conjunction with the lugs of the cap serve to lock the canister into the housing. The invention precludes the escape of any fog from the closure seal between the container and the cap into the housing of the electric fogger and provides for fully efficient use of the fog-producing material.

Electric fogger

An electric fogger includes a housing having a heat source, a timer and a disposable canister containing a fog-producing material such as an insecticide, deodorant, perfume, disinfectant or air freshener. The housing includes a top member and a base member capable of receiving and replaceably holding the disposable canister. The housing contains the heat source such as a hot plate, for heating the insecticide or the like in the canister; a printed circuit board including an electrical switch for activating the heat source and a timer which automatically turns the heat source off after a predetermined period of time; and a pivoting cam adapted to engage the electricl switch on the printed circuit board to allow electricity to flow to the heat source when the pivoting cam engages a lug on the canister upon insertion of the canister into the housing. The fogger is of simple construction and is easy and safe in operation.
