Air Freshener
Patent Abstract
An air freshener that has a source of air freshening chemical with
a fan that is controlled either by an optical device that senses
light or a motion detector is disclosed. When a light is turned
on or motion is detected, the fan will be activated for a predetermined
time period. In certain embodiments, the fan will stop turning after
a predetermined time. In certain preferred embodiments the source
of air freshening chemical is disposed beneath the fan and allows
fragrance to be delivered over time without the fan. The additional
airflow provided by the fan causes more volatile fragrance chemicals
to be removed from the source of air freshening chemical and admitted
into the environment. Preferably, a microprocessor controls the
fan so that a "burst mode" is created by controlling the
frequency and intensity of the pulses of air freshener that are
emitted. Also disclosed is a system for delivering a volatilized
chemical integrated into a robotic vacuum cleaner. A reservoir of
volatile chemicals, such as a fragrance, is volatized and exhausted
by the fan stream through an exhaust duct. As the robotic vacuum
cleaner carries out its automated routine, it adds a scent, antibacterial
chemical or other chemical to the surface being cleaned, e.g., carpeting.
A vehicle interior air freshener comprises a housing adapted for
mounting adjacent to an air outlet through which air flows into
a vehicle interior. The housing includes an air admission opening
for receiving air from the air outlet into the housing interior;
an air outlet opening included in the housing in fluid communication
with the air admission opening. A receptacle is carried by the housing
containing a scent substance for dispersement into the vehicle interior.
A dosing device is carried with the housing for dispensing a predefined
scent charge from the receptacle. An intermediate reservoir element
is carried between the air admission opening and the air outlet
opening so that an air stream colliding with the intermediate reservoir
element entrains the scent substance and flows through the air outlet
opening. The dosing device being disposed a distance from the reservoir
element and manually actuatable to dispense the scent charge onto
the reservoir element upon actuation.
Patent Claims
A hand held vacuum having a tapered centrifugal chamber as its
primary filter. The tapering causes the air stream within the centrifugal
chamber to accelerate as it moves toward the distal end. The air
steam will be able to retain more debris at higher speeds, thereby
improving the efficiency of the centrifugal chamber. This will also
keep more of the debris in the vicinity of the distal end of the
centrifugal chamber and away from its outflow aperture. An air freshener
in a filter housing is also provided. The air freshener will sublimate
into the passing air stream and be emitted with the exhaust from
the vacuum and/or any odor causing particles that may be in the
air stream will be absorbed by the air freshener. The filter will
prevent any dust and debris in the airstream from adhering to the
air freshener and impeding its effectiveness.
Automatic pesticide, insecticide, repellant, poison, air freshener,
disinfectant or other spray-type delivery systems are proposed for
automating the delivery of these items to areas, for controlling
pests easier, for improving environmental conditions, and for making
it easier to freshen the air and to disinfect areas. The device
includes a logic circuit and mechanisms containing a circuit that
will enable a user to program the device to discharge a spray of
its poison, disinfecting or air freshening spray(s) at a pre-selected
time interval or day/time interval chosen in the unit's memory.
An electromechanical valve opens to let contents escape when the
spraying mechanism of the system is activated. The valve connects
to a pressurized spray cylinder and it releases a controlled burst
of insecticide, pesticide, repellant, disinfectant, and or air freshener
as programmed. Control circuits allow the user to set when the system
goes off.
