A device for evaporating liquids for hygienic, medicinal, insecticidal and like purposes comprises a receptacle 1 for the liquid secured with its neck 2 into the lower end 3 of a cylindrical housing 4, a partition disc 7 removably held between the receptacle 1 and said housing 4 and carrying in its middle a short guide tube 8 for a wick 9, a centrally pierced bridge 10 inserted into the lower end of the housing above the partition disc 7, said bridge having a central upstanding circular collar 12 and steps 13 concentric with the collar, a cylindrical wire net 14 slid with its lower end on the collar 12, and a cylindrical electric heating element 15, 16 slid onto the steps 13 and held in place by the inwardly and preferably downwardly turned upper border 17 of the housing 4. Heat insulating washers 18 are inserted between the contacting surfaces of the heating element and the rest of the device. The wick is adjusted by a spindle 21 journalled in a stirrup 22 soldered on the disc 7 and engaging the wick by means of a small toothed wheel 23 entering the tube 8 through a lateral slot thereof. The housing 4 may be screwed on to the receptacle (as shown) or may be connected by a bayonet-socket. The disc 7 may be clamped in the manner shown, or it may be screwed in the screw thread of the housing 4. The liquid receptacle, the cylindrical housing and the core of the heating element are preferably of transparent material.
