Description
“A dispenser for releasing volatiles into the air, and
a method for releasing volatiles into the air”
The present invention relates to a dispenser for releasing volatiles into the air, and in
particular, for releasing volatiles of a volatile fragrant liquid into the air in a confined
area for freshening the air therein. The invention also relates to a method for
dispensing volatiles of a volatile fragrant liquid into the air.
Dispensers for dispensing volatiles of fragrant compositions into the air in confined
areas, such as, for example, toilets, washrooms, corridors, garbage rooms, hospital
sluice rooms, bedrooms, conference areas and the like are known. Such dispensers
can be categorised into two broad categories, namely, dispensers which spray an
atomised volatile fragrant liquid into air, commonly referred to as aerosol sprays, and
dispensers which urge air over an absorbent pad which is impregnated with a
volatile fragrant composition, and in which the pad is adapted for facilitating slow
release of volatiles impregnated into the pad. In general, dispensers of the aerosol
type comprise a housing, which is suitable for wall mounting. A container, commonly
referred to as an aerosol can having an atomising valve thereon which on being
depressed releases an atomised spray of the volatile fragrant liquid contained in the
aerosol can is located in the housing. An actuator is provided in the housing for
periodically depressing the atomising valve for periodically spraying the atomised
liquid into the air. The actuator typically comprises a cam which is rotated by motor
at a relatively low predetermined speed by an electric motor, so that on each 360° of
rotation of the cam the atomising valve of the aerosol spray can is depressed once.
Dispensers which comprise a pad impregnated with a volatile fragrant composition
typically comprise a housing which defines an air duct passing therethrough from an
air inlet to an air outlet. An urging means, typically provided by a motor driven fan, is
located in the air duct for drawing air into the air duct from the confined area through
the air inlet, and for returning the air through_the air outlet to the confined area. The
pad impregnated with the volatile fragrant composition is located within the housing
adjacent the air duct so that the air being urged through the air duct passes over the
pad so that volatiles released from the pad are entrained in the air as it is returned to
the confined area. in general, the pad is readily easily accessible, since in general,
such pads require regular replacement, generally, at intervals of two to three weeks.
This is relatively inconvenient, since in general, such dispensers are serviced by
external service providers, and thus, regular visits of the service providers are
required to sites where such dispensers are located. This is inconvenient, and
indeed, is relatively costly.
There is therefore a need for a dispenser which addresses this problem.
The present invention is directed towards providing a dispenser which addresses the
problem of known dispensers, and the invention is also directed towards providing a
method which addresses the problems of dispensing fragrant volatiles into the air in
a confined area.

Referring to the drawings, there is illustrated a dispenser according to the invention,
indicated generally by the reference numeral 1, which is particularly suitable for
mounting on a wall of a confined area, for example, a toilet, washroom or the like for
releasing volatiles of a volatile fragrant liquid for providing a fragrance in the air in
the confined area. The dispenser 1 also dispenses ozone into the air of the confined
area for freshening the air. The dispenser 1 comprises a housing 2 which in turn
comprises a rear wall 4 adapted for securing to a wall of the confined area, and an
outer casing 5 which is releasably secured to the rear wall 4, and defines with the
rear wall 4 a hollow interior region 6. The outer casing 5 comprises a front wall 7, a
pair of side walls 8 extending from the front wall 7 rean/vardly to the rear wall 4, and
a top wall 9 and a bottom wall 10, both of which extend from the front wall 7 between
the side walls 8 to the rear wall 4.
A sub-housing 11 located in the hollow interior region 6 defines an upstream air duct
12, and comprises inner front and rear walls 13 and 14, respectively, extending
upwardly from a partly semi-cylindrical base 15, and a pair of inner side walls 16 and
17 extending from the base 15 between the inner front and rear side walls 13 and
14. The inner front and rear walls 13 and 14 and the side walls 16 and 17 define an
intermediate air inlet 19 for accommodating air into the upstream air duct 12. An
intermediate air outlet 20 formed by an elongated slot extending across a portion 30
extending from the base 15 accommodates air from the upstream air duct 12.
An urging means comprising a fan 21 is located in the lower end of the upstream air
duct 12, and is rotatable about a rotational axis which substantially coincides with the
axis of generation of the partly semi-cylindrical base 15. An electrically powered
drive motor 23 rotates the fan 21 in the upstream air duct 12 for urging air through
the upstream air duct 12 from the intermediate air inlet 19 to and through the
intermediate air outlet 20.
The outer casing 5 defines with the rear wall 4 a downstream air duct 24 through
which air urged from the upstream air duct 12 through the intermediate air outlet 20
is urged to a main air outlet 25 formed by a plurality of elongated parallel outlet slots
26 formed in a lower portion of the front wall 7 of the outer casing 5. A main air inlet
27 formed by a plurality of elongated parallel slots 28 located in the top wall 9 of the
outer casing 5 accommodates air from the confined area to the upstream
intermediate air inlet 19. The fan 21 draws air in from the confined area through the
main air inlet 27, and in turn through the intermediate air inlet 19, the upstream duct
12, the downstream duct 24 and returns the air to the confined area through the
main air outlet 25.
A holding means, namely, a tray 30 is located on a tray support 31 extending
outwardly from the rear wall 4, and carries an absorbent fibre pad 32 which is
impregnated with a volatile fragrant liquid. The tray support 31 extends from the rear
wall 4 and supports the tray 30 at an angle so that the absorbent fibre pad 32 is
located in the path of the air being urged through the downstream air duct 24 as it is
being urged through the main outlet 25. In this way volatiles released from the
absorbent pad 32 are entrained in the air as it is urged through the downstream air
duct 24 and returned to the confined area through the main air outlet 25 for providing
a fragrance in the air in the confined area.
Two reservoirs comprising a pair of containers 34 are located in the hollow interior
region 6 and store two volatile fragrant liquids from which the liquid can be
selectively metered onto the absorbent pad 32. A metering means provided by a
pair of metering piston pumps 33 also located in the hollow interior region 6 and
coupled to the containers 34 by tubes 36 meter a selected one of the volatile fragrant
liquids from the appropriate one of the containers 34. An electrically powered
actuator 35 in the hollow interior region 6 operates the piston pumps 33. Valves 37
in the tubes 36 are provided for manual selection of the fragrant volatile liquid to be
metered from the containers 34 by the metering pump 35. A discharge tube 38
extending from the piston pumps 33 to the tray 30 accommodates metered
quantities of the selected volatile fragrant liquid from the piston pumps 33 to the
absorbent pad 32. Typically, as will be described below, a few drops of the selected
volatile fragrant liquid is dispensed periodically by the corresponding pump 33 onto
the absorbent pad 32.
An ozone generating means, namely, an ozone disc 40 located in the intermediate
air outlet 20, and operated under the control of an electrically powered ozone
generator 41 generates ozone. The ozone disc 40 extends into the path of the air
being urged through the intermediate air outlet 20 for releasing ozone into the air as
it is being urged therethrough for freshening the air to be discharged into the
confined area.
Referring to Fig. 11, an activating means comprising a first relay 42 selectively
applies an electrical power supply to the ozone generator 41 for operating the ozone
generator 41 for generating the ozone. Electrical power is supplied to the actuator
for the piston pumps 33 through a second relay 43. A control means, in this
embodiment of the invention an electronic control circuit illustrated in block
representation and indicated by the reference numeral 45 controls the operation of
the first and second relays 42 and 43 for supplying the electrical power to the ozone
generator 41 and the actuator 35. A timing means provided by a programmable
timer 46 in the control circuit 45 controls the relays 42 and 43 for selectively
operating the ozone generator 41 and the piston pumps 33, so that when the ozone
generator 41 is generating ozone, the piston pumps 33 are disabled, and vice versa.
The timer 46 is programmed to operate the first relay 42 for operating the ozone
generator 41 for relatively long first predetermined time periods for releasing ozone
into the air as the air is urged from the upstream air duct 12 to the downstream air
duct 24. At the end of each first predetermined time period, the first relay 42 is
deactivated, for in turn disabling the ozone generator 41. Simultaneously, the
second relay 43 is activated for a short second predetermined time period for
operating the actuator 35 and in turn the piston pumps 33 for dispensing a few drops
of the volatile fragrant liquid onto the absorbent pad 32. At the end of the second
predetermined time period the timer 46 deactivates the second relay 43, for in turn
disabling the piston pumps 33. Additionally, at the end of the first predetermined
time period, as well as commencing timing of the second predetermined time period,
the timer 46 also commences to time a first predetermined time interval, which is of
sufficient time to allow all the volatiles dispensed by the appropriate one of the piston
pumps 33 onto the absorbent pad 32 in the second predetermined time period to
have evaporated from the absorbent pad 32. At the end of the first predetermined
time interval, the first relay 42 is again activated by the control circuit 45 and the
timer 36 commences to time the next first predetermined time period, and so
operation of the first and second relays 42 and 43 and in turn the ozone generator
and the piston pumps 33 continues.
Accordingly, the dispenser 1 is operated so that while the volatiles from the volatile
fragrant liquid are being released from the absorbent pad 32 and entrained in the air
being urged through the upstream and downstream air ducts 12 and 24, and in turn
returned to the confined area, no ozone is released into the air, and vice versa, when
ozone is being released into the air being passed through the upstream and
downstream air ducts 12 and 24, no volatiles from the volatile fragrant liquid are
released into the air. This has the advantage of minimising the use of the volatile
fragrant liquid, and thus, maximising the period for which a full charge of the volatile
fragrant liquid in the container 34 lasts. Additionally, periodic release of the volatiles
into the air of the confined area is enough for continuously maintaining the air in the
confined area fragrant, and during periods while no volatiles of the volatile fragrant
liquid are being released into the air, the air is freshened by the ozone released by
the ozone disc 40.
A keypad 47 mounted on the inner side of the front wall 7 of the outer casing 5 and
accessible through openings 48 in the front wall 7 is provided for setting the timer 46
for timing the first and second predetermined time periods and the first
predetermined time interval to appropriate desired time periods.
in this embodiment of the invention the first predetermined time period may be any
desired period during which ozone is to be dispensed into the confined area. The
second predetermined time period is sufficient to permit the appropriate piston pump
33 to dispense a few drops of the volatile fragrant liquid, typically, three to five drops
onto the absorbent pad 32. The first predetermined time interval is sufficient to allow
substantially all of the volatiles of the volatile fragrant liquid dispensed onto the
absorbent pad 32 during the second predetermined time period to be released into
the air.
A third relay 49 operated under the control of the control circuit 45 supplies electrical
power to the motor 23 of the fan 21. in this embodiment of the invention the motor
23 is continuously powered for in turn continuously powering the fan 21 once the
dispenser 1 is powered up. A connecting means, namely, a connector 50 is
provided for electrically coupling the dispenser 1 to a 220 volt AC mains power
supply.
A filter 51 is located in the hollow interior region 6 between the main air inlet 27 and
the upstream air inlet 19 for filtering large airborne particles from the air as the air is
being drawn into the upstream duct 12. in this embodiment of the invention the filter
51 comprises a replaceable carbon filter, and is suitable for removing dust particles,
tissue particles, clothing fibres, pollen, body scale and other such contaminating
particles from the air.
In use, with the dispenser 1 mounted on a wall, generally at a relatively high location
on a wall in a confined area, such as, for example, a toilet, a washroom or the like
and connected to an AC mains power supply, the dispenser 1 is ready for use. The
containers 34 are charged with the desired volatile fragrant liquids, and the container
34 from which the volatile fragrant liquid is to be metered by the appropriate piston
pump 33 onto the absorbent pad 32 is selected by operating the appropriate valve
37 in the opened state. The other of the two valves 37 is operated into closed state.
Once the dispenser 1 is powered up, the fan 21 is continuously driven by the drive
motor 23, thereby urging air into the upstream air duct 12 through the main air inlet
27 from the confined area, and in turn through the downstream air duct 24 and
through the main air outlet 25 where the air is returned to the confined area.
initially, the timer 46 times the first predetermined time period during which the
ozone generator 41 is operated for releasing ozone into the air as it is returned to the
confined area for freshening the air in the confined area. At the end of the first
predetermined time period the ozone generator 41 is deactivated and the actuator
is operated for the second predetermined time period for in turn operating the
piston pumps 33 for discharging a few drops of the selected volatile fragrant liquid
onto the absorbent pad 32. Simultaneously as the timer 46 commences to time the
second predetermined time period, the timer 46 commences to time the first
predetermined time interval, and during the first predetermined time interval, the
ozone generator 41 is deactivated and only volatiles released from the absorbent
pad 32 are entrained in the air as the air is being urged through the downstream air
duct 24 and returned to the confined area for providing a fragrance in the confined
area. At the end of the first predetermined time interval the ozone generator 41 is
again activated for releasing ozone into the air being passed from the upstream air
duct 12 to the downstream air duct 24 for freshening the air being returned to the
confined area, and the timer 46 again times the first predetermined time period, and
so operation of the dispenser continues.
At any time when it is desired to change the fragrance of the volatiles being released
from the absorbent pad 32 into the air passing through the downstream air duct 24,
the valves 37 in the tubes 36 are appropriately reset. To access the containers 34
and the valves 37, the outer casing 5 is released from the rear wall 4 and removed
therefrom. Removal of the outer casing 5 also provides access to the ozone
generator 41 should it be necessary to replace an ozone disc 40, and to the
absorbent pad 32, should it be desired or necessary to replace the absorbent pad
with a fresh pad.
While the dispenser according to the invention has been described as comprising a
pair of reservoirs provided by a pair of containers for storing two volatile fragrant
liquids, it will be readily apparent to those skilled in the art that a single container
may be provided, and indeed, in certain cases, it is envisaged that where two
containers are provided, a similar volatile fragrant liquid may be contained in both
containers.
While the dispenser has been described as comprising an ozone generator, in
certain cases, it is envisaged that the ozone generator may be omitted.
While first and second predetermined time periods and a first predetermined time
interval of appropriate time durations have been described, it will be readily apparent
to those skilled in the art that first and second predetermined time periods and a first
predetermined time interval of other time duration may be selected. Indeed, in
certain cases it is envisaged that the ozone generator may be operated while
volatiles of the volatile fragrant liquid are being released into the air. The advantage
of alternately releasing ozone and volatiles into the air is that the volatile fragrant
liquid is conserved with virtually no loss of freshness of the air in the confined area.
While the dispenser according to the invention has been described as being suitable
for powering by mains electricity, it is envisaged that the dispenser may be battery
powered instead of being mains powered, or may be provided to be suitable for dual
powering either by a battery or by mains electricity.
