Abstract
Abstract of the Disclosure:
Liquid atomizer having a vibration generator for generating vibrations, an atomizer element receiving the vibrations, and a container with liquid to be atomized. Liquid is transported solely and directly from the container to the atomizer element by a wick of elastically resilient material in contact with liquid in the container and at a point remote from the liquid in the container, mechanically coupled to the atomizer element by disposing the wick against the atomizer element. A tube may surround the wick until almost to the coupling point.

Summary of the Invention It is now an object of the present invention to provi~e a llquid at~mizer OI` the type mentloned ~t the outset in which the liquid ~eed is s~bstantially simplified and the atomization is impsoved.
With the ~oregoing and other objects in view there is provided, in accordance with the invention, an atomiæer for liquids comprising a ~ibration generator for generating vibrations, an atomizer e~e-ment to which the ~ibrations are transmitted~ said atomizer ele-ment having a surface onto which liquid is fed and from which surface atomize~ liquid is released, a container ~or holding a body of liquid below the atomizer elemenb, a housing supporting the vibra-tion generator, the atomizer element, and the container~ a rod-shaped wick of elastically resilient material in contact with-the body o~ liquid in the container to cause the liquid to move up-wardly along the ~ick, means for elastically pressing the wick against the atomizer-elemen~ at a point remote from the b~dy of liquid in the container to cause liquid ~rom the wick to discharge -: .
directly onto the atomizer element, said wick alone feeding liquid from the container directly to the atomizer element.
Other features which are considered as characteristic fo~ the invention are set forth-in the appended claimsO
Although the invention is illustrated and described herein -as embodiedin atomizer for liquid, it is nevertheless not .~, .

equ~valents of the clalms, Brief Description o:~ the Drawing ~ ~ . . .
The in~ention, however, together with ~ddltional obJec ts and advantages thereo~ will be best understood ~rom the ~ollowing description when read ln connection with the accompanying drawlng which diagram~atically illu~trates in sect~on, an atomizer for liquid in accordance with the present invention.
Detalled Description o~ the Inve~tion In accordance with the invention, a wick conslsting of elastical-ly resilient mQterial serves alone for ~eedlng and making ava~lable a liquid. The w~ck is in communicatlon on the one hand with a liquid in a liquid contalner and on the other hand rests or presse~ elasticall~ aga~nst the atomizer elemen~
Contrary to kno~ liquid atomizers, only a single element is required for feeding and making available a liquid, namely a wick. This not only repre~ents a design simplification but lt also ensures that all the liquid taken from the liquid :
