Abstract
Abstract A socket-mounted illuminating and air freshening device which is adapted to be supported on a conventional electrical wall outlet socket to provide, alternatively or simultaneously, illumination and circulation of air through an air freshening material. The device of the invention is light weight and is inexpensive to operate even in simultaneous illumination and air circulating modes. The device is capable of a wide versatility of use and may be oriented in any direction for effective operation.

Claim 1
Independent Claim
215 words
A portable illuminating and air freshening device to be electrically coupled to and supported from a standard wall-mounted electrical receptacle comprising a housing having an air inlet and an air outlet with a path for air flow therebetween, said housing further including security clamp means affixed to the exterior of said housing for connection to a wall receptacle plate to aid in the support thereof from the electrical socket, air circulating means carried by said housing and electrically energizable for drawing air thereinto through said air inlet and discharging the air drawn thereinto out through said air outlet, an externally mounted male electrical contact member carried on an outer portion of said housing and directly engageable into a wall mounted electrical receptacle having a female electrical contact for coupling a source of electrical power within said housing, said externally mounted male electrical plug member carried on an outer portion of said housing comprising a support for connecting said housing directly to the wall mounted electrical receptacle when physically inserted therein, and illuminating means carried by said housing and electrically energizable for emitting light therefrom, said air circulating means and said illuminating means being electrically coupled to said externally mounted male contact member for selective energization thereof in response to the coupling of electrical power thereto.

A portable illuminating and air freshening device to be electrically coupled to and supported from a standard wall-mounted electrical receptacle comprising a housing having an air inlet and an air outlet with a path for air flow therebetween, said housing further including security clamp means affixed to the exterior of said housing for connection to a wall receptacle plate to aid in the support thereof from the electrical socket, air circulating means carried by said housing and electrically energizable for drawing air thereinto through said air inlet and discharging the air drawn thereinto out through said air outlet, an externally mounted male electrical contact member carried on an outer portion of said housing and directly engageable into a wall mounted electrical receptacle having a female electrical contact for coupling a source of electrical power within said housing, said externally mounted male electrical plug member carried on an outer portion of said housing comprising a support for connecting said housing directly to the wall mounted electrical receptacle when physically inserted therein, and illuminating means carried by said housing and electrically energizable for emitting light therefrom, said air circulating means and said illuminating means being electrically coupled to said externally mounted male contact member for selective energization thereof in response to the coupling of electrical power thereto.
Claim 3
Dependent Claim
243 words
A portable illuminating and air freshening device to be electrically coupled to and supported from a standard wall-mounted electrical receptacle comprising a housing having an air inlet and an air outlet with a path for air flow therebetween, air circulating means carried by said housing and electrically energizable for drawing air thereinto through said air inlet and discharging the air drawn thereinto out through said air outlet, an externally mounted male electrical contact member carried on an outer portion of said housing and directly engageable into a wall mounted electrical receptacle having a female electrical contact for coupling a source of electrical power within said housing, said externally mounted male electrical plug member carried on an outer portion of said housing comprising a support for connecting said housing directly to the wall mounted electrical receptacle when physically inserted therein, said externally mounted male electrical contact member carried on an outer portion of said housing having at least one female electrical contact formed on a free end thereof for coupling the source of electrical power into which said male electrical contact member is engaged to a second male electrical contact member upon insertion thereof into said female electrical contact, and illuminating means carried by said housing and electrically energizable for emitting light therefrom, said air circulating means and said illuminating means being electrically coupled to said externally mounted male contact member for selective energization thereof in response to the coupling of electrical power thereto.
Claim 4
