Localized surface volatilization

A portable apparatus for dispersing a volatile active into air, comprising:

• a base;
• a reservoir containing a composition having a volatile active;
• a holder for mounting said reservoir to said base;
• a wick having an emanating surface and communicating with said composition for delivering said composition to said emanating surface;
• a heating element in contact with said emanating surface;
• a source of power communicating with said heating element to heat said heating element and vaporize said volatile active;
• and
• a spring providing a force to maintain said wire heating element in contact with said emanating surface.

A portable apparatus for dispersing a volatile active into air,

• comprising:
• a base;
• a refill assembly comprising a reservoir containing a composition having a volatile active, a wick having an emanating surface and communicating with said composition for delivering said composition to said emanating surface, and a heating element in contact with said emanating surface;
• a holder for removably mounting said refill assembly to said base;
• a source of power communicating with said heating element to heat said heating element and vaporize said volatile active;
• a spring providing a force to maintain said heating element in contact with said emanating surface;
• a cover attachable to said base to enclose said refill assembly, holder and spring, and including at least one air inlet and one air outlet;
• and
• a fan mounted to move a current of air from said inlet past said emanating surface to cause egress of said volatile active from said air outlet.
