Total Claims: 6
Claim 1
Independent Claim
166 words
A thermal vaporizer with an integral plug for insertion into an electrical outlet, comprising: a vaporizer body; a ring heater mounted within said vaporizer body; a wick having a cross sectional area, for drawing up a chemical solution from a bottle which wick is insertable into the ring heater concentrically therewith; a socket disposed under said heater with spacing therebetween; a bottle fittable in the form of a removable cap to said socket such that when the bottle is in place, one or more openings are provided for said wick; at least one air outlet formed in the top portion of said vaporizer body, said air outlets having a total opening area that is 2 to 40 times the cross sectional area of said wick; at least one air intake formed in the bottom portion of the body and having a total opening area that is 1.5 to 20 times the cross sectional area of said wick; and a plug electrically connected to said ring heater.
Claim 2
Dependent Claim
