초록 ▼

An aroma generator that is rendered operative only when a switch-controlled electric light bulb is in a predetermined state which is either “on”or “off,”the generator then functioning to discharge an air current conveying an aromatic vapor which modifies the prevailing atmosphere. Included in the generator is a motor-driven fan that forces air through an air-permeable cartridge containing an aroma supply. The motor is connected to a battery through a signal-responsive electronic relay having time delay means such that when the relay is activated by a signal to turn on the fan, it is thereafter automatically deactivated after a predetermined time period. Applied to the relay is a binary signal derived from a light sensor adjacent the light bulb to intercept light rays therefrom, the signal being positive when the bulb is switched “on”and negative when it is switched “off.”In one embodiment, the relay responds only to a positive signal, in which event the aroma generator is rendered operative for a predetermined period when the bulb is switched “on.”In another embodiment, the relay responds only to a negative signal, in which event the aroma generator is rendered operative for a predetermined period when the bulb is switched“off.

In combination with a switch-controlled light bulb disposed in a chamber, an aroma generator which is rendered operative to modify the atmosphere of the chamber only when the switch connected to the light bulb is operated to put the bulb in an “on”or an “off”state, said generator comprising: A. a case disposed at a position adjacent the bulb and including a compartment for housing of a battery; B. a low-voltage direct-current motor coupled to a propeller fan and which is housed in said case; C. a light sensor mounted on said case to intercept light rays from said light source to produce a binary signal pulse when the switch is operated, the polarity of the pulse being positive in said “on”state and negative in the “off”state; D. an air-permeable cartridge containing an aroma supply and disposed in said case in operative relation to said fan to exude an aroma into the atmosphere of the chamber at a relatively rapid rate only when an air current is forced through said cartridge by said fan; and E. signal responsive electronic relay coupled to said sensor and activated by a signal pulse of a given polarity, to connect said battery to said motor to render the generator operative, said relay including a time delay which automatically deactivates the relay after a predetermined period whereby the generator is cut off at the conclusion of the period and is not again rendered operative until the switch is again operated to produced a signal pulse of said given polarity.
