Abstract
An apparatus for freshening air within confined spaces such as the driver or passenger compartment of vehicles, or rooms within buildings, includes a housing which has an elongated cylindrical rear section adapted to plug into a standard cigarette lighter socket of the type commonly found in vehicles. An electric motor within the front section of the housing contains a propeller fastened to its shaft, the motor being powered through electrical contacts protruding through the rear section of the housing and contacting complementary contacts within the socket. A perforated dome-shaped cover removably fastenable to the larger diameter front section of the housing containing the propeller has a concave interior space adapted to hold a disposable scent producing an odor absorbing perforated disc.
Claims15
An apparatus for freshening air within confined spaces comprising:
- (a) a housing having an elongated cylindrical end portion adapted to be inserted into an electrical power socket, said housing having external electrical contacts adapted to conductively contact internal electrical contacts within said socket,
- (b) an electrical motor contained within said housing, the input terminals of said motor being electrically coupled to said external contacts in a manner providing electrical power to said motor when said housing is plugged into said power socket,
- (c) an air displacing element fastened to the output shaft of said motor, said air displacing element being enclosed within said housing,
- (d) a perforated end cap covering said end of said housing opposite of said end containing external electrical contacts, said end cap adapted to removably attach to said housing and providing a space between said air displacing element and said perforations in said end cap for a thin sheet of odor absorbing, scent dispersing material.
An apparatus for freshening air within a confined space comprising;
- (a) an elongated circular transverse cross-section housing having an elongated hollow cylindrical rear section and a shorter, larger diameter hollow front section coaxial with said rear section, said cylindrical rear section adapted to be inserted into an electrical power socket, and including external electrically conductive elements protruding through said cylindrical rear section adapted to resiliently engage coplementary internal contacts within said socket,
- (b) a generally cylindrical electrical motor contained in a generally coaxial position within the hollow interior space of said elongated hollow cylindrical rear section, each of the electrical power terminals of said motor being conductively connected to a separate one of said external conductive elements,
- (c) a propeller fastened to the output shaft of said motor, said propeller located coaxially within said larger diameter front section of said housing, and
- (d) a generally circular cross-section dome-shaped end cap removably fastenable coaxially to said front section of said housing, thereby enclosing said front section and providing a space for a thin sheet of odor absorbing material, said end cap containing a plurality of axially disposed perforations communicating with the interior space of said front section.
