Abstract
An apparatus adapted to provide in an atmosphere one of at least three volatile liquids, the apparatus comprising a source of air current, radially extending from the source of air current a plurality of coplanar air channels, corresponding to the number of volatile liquids, placed such that the air current flows through them, each channel leading to a different volatile liquid-emitting member and then into the atmosphere; and located in each channel between the source and the volatile liquid-emitting member, means of blocking the channel and preventing the flow of air therethrough. The apparatus allows an easy change from one liquid to another and control over the time of the emission of each liquid.
Claims12
An apparatus adapted to provide in an atmosphere one of at least three volatile liquids, the apparatus comprising:
- (a) a source of air current providing an air current flow;
- (b) a plurality of coplanar air channels radially extend from the source of air current and correspond to a plurality of reservoirs containing volatile liquids, the channels are arranged such the air current to flows through them a plurality of second channels into the atmosphere, each of the plurality of second channels being connected to one of the reservoirs containing volatile liquid-emitting member;
- and
- (c) blocking means are disposed located in each air channel for selectively preventing the air current flow therethrough.
(canceled)
A method of disseminating into an atmosphere at least one volatile liquid selected from at least three liquids provided in a dissemination device, comprising the steps of
- providing an air current generated by a source of air current through a plurality of coplanar air channels the plurality of air channels correspond in number to the number of volatile liquids,
- providing individual channels extending radially from the source of air current to one of a plurality of volatile liquid-emitting members and to the atmosphere,
- blocking selectively any channel between the air current flow and the any volatile liquid-emitting member.
