Liquid vaporizing, diffusing and dripping

摘要

Apparatus including a liquid vaporizer having a first wick of linear shape, a bottle for holding the liquid to be vaporized and a gravity-flow metering device having a second wick. The bottle has a closing cap to which two tubes are connected. One tube discharges the liquid from the bottle and the other extends through the cap to the opposite end of the bottle for counteracting the vacuum which is produced when liquid is discharged. The end of the discharging tube extends outwardly of the cap further than the end of the other tube so that a pool is produced in the dispenser. The level of the pool is limited by the position of the end of the tube for counteracting the vacuum. The second wick is of J-shape; one end is immersed in the pool and the other end is suspended over the first wick so that liquid absorbed at the immersed end drips from the second wick on the first wick and is evaporated and diffused from the first wick. There is also disclosed a bottle having a spout with two holes near its end; the lower hole for discharging the liquid and the upper hole for admitting air to counteract the vacuum. There is also disclosed a method of vaporizing and diffusing a liquid whose steps include absorbing a liquid in a first wick and dripping the absorbed liquid on a second wick from which it is vaporized and diffused.
