24


, which receives the motor assembly


3


, a receiving chamber


22


which receives the perfume container


10


, and a plurality of air inlets


23


. The motor assembly


3


is comprised of a rear cover

33


, and a motor


36


mounted inside the front cover


32


and the rear cover


33


between the axle bearing


35


and the muffler


34
