ABSTRACT:
A capillary pump for a fragrance dispenser has a reservoir for holding fragrance oil. The reservoir is capped with a silicone rubber cap with a vapor port therein for emitting vaporized fragrance oil. A capillary tube has its bottom end extending to the bottom of the reservoir where capillary action draws fragrance oil up into the capillary tube. A heating element inside the capillary tube vaporizes fluid drawn into the tube. Electrical leads for the heating element exit through the silicone rubber cap. The cap, capillary tube and heating element form a unit for insertion of the capillary tube and heating element into the reservoir.
