Liquid electrical vaporiser

Abstract

A liquid electric vaporiser (1, fig. 2) comprising a housing (3, fig. 2), a detachable refill bottle (4, fig. 2) having a wick (5, fig. 2) in fluid communication with a material to be dispensed therefrom and extending to an area proximate with a heater (2, fig. 2). There is a power source operably connectable to the heater to supply power to the heater and vaporise the fluid, and a control circuit configured to control the supply of power to the heater based on a micro cycle and a macro cycle. The micro cycle comprises alternating between a first operation profile for a first predetermined time, and a second operation profile for a second predetermined time during which the power supplied to the heater is close to or equal to zero. The power supplied to the vaporiser increases in each subsequent first operation profile during the first predetermined time during a first number of cycles under the macro cycle, and decreases in each subsequent first operation profile during a second number of cycles under the macro cycle.
