FIELD OF THE INVENTION
This invention is directed to an apparatus (typically in the form of
a small box) which can better distribute the smoke from a mosquito
coil/candle etc or which can better distribute the vapour from a vaporiser. In a
broad form, the invention is directed to a fan containing apparatus which can
better distribute any type of beneficial vapour/smoke/gas etc. The beneficial
action may comprise an insect repellent, a fragrance, a deodorizing agent and
A very common way to deter or repel mosquitoes and biting
insects is to place a mosquito coil or a mosquito candle in the area where the
deterrent effect is required. The smoke from the mosquito coil and the
vapour from the mosquito candle provides a deterrent to biting insects. A
disadvantage with these coils and candles is that the effective deterrent area
is not very large. If the mosquito coil or candle is placed in a closed room, it
is found that the greatest deterrent occurs above the coil or candle as the
smoke/vapours tend to move upwardly. Conversely, if the mosquito coil or
candle is placed outside, a breeze will tend to blow the smoke/vapour away
from the deterrent area.
With mosquitoes, it is noticed that mosquitoes tend to
congregate in certain areas. In a room, it is noticed that mosquitoes tend to
congregate about the corners of the room. However, the smoke from the
mosquito coil or the vapour from a mosquito candle does not effectively
extend into this area.
Many types of vaporising devices are known. One common type
of vaporising device is electrically operated and can be plugged into a power
socket. The device contains a small reservoir of liquid repellent/fragrance/
deodorizing agent etc and contains a small heating device which heats the
liquid or a proportion of liquid. Again, a disadvantage with this device is that
the treatment area is not very large. To properly deodorise an entire room, or
to provide a repelling action in an entire room, it takes a long time before the
vapours/smoke extend throughout the room.
It will be clearly understood that, if a prior art publication is
referred to herein, this reference does not constitute an admission that the
publication forms part of the common general knowledge in the art in
Australia or in any other country.
OBJECT OF THE INVENTION
The present invention is directed to a simple yet extremely
useful device or apparatus which can assist in dispersing the smoke from a
mosquito coil, the vapour from a mosquito candle, the vapour from a
vaporiser etc in a more efficient manner.
It is an object of the invention to provide an apparatus which
may overcome at least some of the above-mentioned disadvantages and/or
provide the public with a useful or commercial choice.
In one form, the invention resides in an apparatus to dispense a
beneficial gas/smoke/vapour, the apparatus having an enclosure, the
enclosure adapted to contain a gas/smoke/vapour generating device, a fan to
pass air at least partially through the enclosure and to entrain at least some of
the gas/smoke/vapour, an outlet through which the gas/smoke/vapour can
The term "beneficial gas/smoke vapour" includes the smoke
from a mosquito coil, vapours from a vapourising device such as a candle, an
electrically operated vapouriser, and other devices that generate a
smoke/gas/vapour that repels, kills or otherwise deters insects, moths and
other undesirable creatures.
It is preferred that an elongate tube is provided, and that the
tube has at least one opening which is operatively associated with the outlet
such that gas/smoke/vapour passing through the outlet passes at least
partially through the tube. The tube may have a length of between 1-10 m or
even more, and may have a diameter of between 5-50 mm or even more.
The tube may be perforated at least partially along its length and therefore
make comprise a perforated ducting. Preferably, the tube is perforated along
its length which allows the smoke/gas/vapour to pass out of the perforations.
The tube may comprise a tube having sections which are not perforated and
sections which are perforated. The smoke/gas/vapour will pass along the non
perforated section of the tube and through the openings in the perforated
section of the tube. This allows the tube to be laid in such a manner that the
smoke/gas/vapour only passes into a desired area. This can be achieved, if
necessary, by providing separate tubes which can be fitted together with one
tube not been perforated and another tube being perforated. This concept
can be extended to include tube lengths having different types, sizes and
numbers of perforations to control the volume of smoke/gas/vapour passing
out of the tube at any particular place.
The tube, or perforated ducting, can be made of any suitable
material which may include plastics. The tube is preferably sufficiently flexible
to allow it to be placed in desired areas.
The tube may have closeable openings to provide versatility to
the device. This can be in the form of a collar which is slideable over the tube
and which can close off some openings. Valves, taps and the like can also be
present to direct the smoke to desired parts of the tube.
The tube may be substantially circular if desired although this is
not necessary. Alternatively, the tube may be rectangular, oval, or have other
shapes. It is considered that the tube may have a discreet or "low-profile"
and this can be achieved by giving the tube a flattened oval shape, or giving
the tube a rectangular shape having a low-profile.
The tube may be positioned along the ground to enable the
smoke etc to be directed into a suitable region. In one form, the tube may be
simply laid along the ground. However, the tube may also be suspended
from a wall, post, or anchored to the ground or otherwise placed in position.
Thus, the invention may also comprise fasteners, attachment, clips, or other
types of accessories to enable the tube to be placed in a desired position.
These fasteners etc may be separate and the tube may be attached to the
fasteners; alternatively, the fasteners make comprise part of the tube or may
be otherwise attached to the tube.
Suitably, the fan passes air from outside the enclosure and into
the enclosure. In this manner, the smoke laden air does not pass through the
fan. However, in another form, the fan may form part of a fan enclosure
which has an inlet and an outlet, the inlet of the fan enclosure being in
communication with the enclosure, and the outlet of the fan enclosure being
in communication with the outside of the apparatus. In this version of the
invention, the smoke laden air does pass through the fan.
In another form, the invention resides in an apparatus, the
apparatus having a first enclosure adapted to contain a mosquito
coil/candle/vaporising device, an inlet to allow air to pass into the first
enclosure, a fan enclosure which has an inlet and an outlet, a fan, the inlet of
the fan enclosure being in communication with the first enclosure, and the
outlet of the fan enclosure being in communication with the outside of the
Thus, in accordance with the invention, a commercially available
mosquito coil or mosquito candle can be lit and placed in the enclosure. The
fan can then be started which will blow the smoke containing air more
vigorously into a room/outside area etc.. There is no need to provide a
complicated system to produce the smoke/vapour as the apparatus allows a
conventional mosquito coil, mosquito candle etc to be used.
In an extremely broad form, the invention can comprise an
apparatus having a single enclosure in which the mosquito coil etc can be
placed. A fan can blow air through the enclosure and through an outlet to
direct smoke laden air to a desired area. The fan can be placed in the
enclosure, next to the enclosure etc. The fan can be reversed such that the
air can be sucked through the enclosure from the outlet and through the inlet.
Other changes and modifications are envisaged.
The apparatus is typically box shaped in configuration and small
enough to be placed on the ground, on a shelf, on a stand etc. However,
there is no need for the apparatus to be box shaped and other types of
shapes are envisaged. However, the apparatus will typically have a top wall,
a bottom wall, a rear-wall, sidewalls and a front wall. The enclosure should
be large enough to accommodate the mosquito coil etc which is to be placed
in the enclosure. The size of this can vary to suit.
The enclosure typically has an air inlet to allow air to pass into
the enclosure. The air inlet may comprise a series of perforations in one or
more walls of the enclosure, although other arrangements are envisaged.
The enclosure is typically provided with some form of door/flap
or other type of access means to allow the mosquito coil etc to be placed into
the first enclosure. Typically, a side wall of the apparatus is hinged to provide
a door. It is preferred that one side wall is hinged by a top horizontal hinge
which means that the door will naturally fall to a closed position. This allows
the apparatus to be simple in design.
It is preferred that the air inlet comprises one or more apertures
in the door. Thus, the door can be seen as a vented door. However, the air
inlet may be another part of the apparatus. For instance, if the fan draws air
from the outside of the enclosure, the air inlet may comprise the inlet of the
It is preferred that the enclosure is made of heat resistant
material. This minimises any chance of damage to the first enclosure by
virtue of a mosquito candle, a lit mosquito coil etc.
In one embodiment of the invention, the apparatus may
comprise a pressurised unit. In this version, the fan may have an inlet
communicating with the outside of the enclosure, and an outlet
communicating with the inside of the enclosure. Thus, air is blown into the
inside of the enclosure causing a degree of pressurisation. The enclosure
may comprise an outlet through which the pressurised air can pass. The
outlet may be attached to or otherwise in communication with a perforated
ducting as described above. Suitably, the mosquito coil/candle/vaporising
device etc is positioned in the enclosure.
In another embodiment of the invention, the apparatus is
provided with a venturi. The venturi may comprise a tube in the enclosure.
One end of the tube is associated with the fan outlet such that pressurised air
blows from the fan outlet and into the venturi. The other end of the venturi
can be associated with the outlet. As the air blows into the venturi, it provides
a region of low-pressure which sucks in adjacent air. The adjacent air
comprises the smoke/gas/vapour laden air in the enclosure. An advantage of
this arrangement is that smoke does not pass through the fan.
The apparatus may have a fan enclosure. The fan enclosure
typically comprises a shroud about a fan, the shroud having an inlet and an
outlet. Other types of arrangements are envisaged however it is preferred
that the design of the fan and fan enclosure is such that there is little mixing
of incoming air and exiting air as the function of the fan is to blow the
smoke/vapour laden air out of the apparatus. The fan enclosure may be
formed in a second enclosure of the apparatus. The second enclosure may
be separated from the first enclosure and this can be achieved using a
partition wall and the like. This arrangement can prevent damage to the fan.
The inlet of the fan enclosure may be in communication with the first
enclosure. Typically, the fan enclosure is attached to one wall of the first
enclosure, and an opening is provided in the wall to allow air to pass into the
inlet of the fan enclosure. If desired, a screen, filter etc may be provided. The
outlet of the fan enclosure can communicate with the outside of the
apparatus. In a simple form the outlet may communicate with or be part of a
tube, conduit, or other type of enclosure which funnels the air passing through
the outlet towards an outlet in the apparatus.
The outlet in the apparatus may comprise a valve or other type
of opening. The advantage of this arrangement is that a flexible hose can be
attached to the outlet. The hose may be perforated and blocked at the end to
force the mosquito coil smoke etc to pass through the perforations in the
hose. The hose may be several metres long and may be placed wherever
necessary in a room or an outdoor area to provide a much greater repellent
action than would be possible with a single mosquito coil or even a number of
mosquito coils. Thus, one advantage of the apparatus is that a single
mosquito coil/mosquito candle can be as effective in a larger area which
previously would require a large number of candles/coils etc. Moreover, by
using the flexible hose the repellent smoke/vapour etc can be channelled to
precisely where needed.
Alternatively, the apparatus may be provided with a second
enclosure/third enclosure and like which may be provided with an open top,
an elongate slot etc to allow smoke/vapour to pass from the apparatus. While
this arrangement does not contain a flexible hose, it will still disperse the
smoke/vapour more efficiently.
The fan may be electrically powered. In one form of the
invention, the fan may be powered by a battery. In another form of the
invention, the fan may be powered by a rechargeable battery and the battery
can be recharged from a power source using conventional techniques. In
another form, the fan may be powered from a vehicle cigarette lighter socket,
or mains power. It is envisaged that the fan may also be solar powered. It is
envisaged that the fan may be a variable speed fan and some form of control
knob etc can be provided to adjust the rotational speed of the fan. The fan
may be controlled by an on/off switch or by any other suitable means.
The apparatus need not be limited to use with a mosquito coil,
mosquito candle, an oil or any other product which is lit or burnt to provide the
repellent action. For instance, the apparatus is sufficiently versatile to enable
it to be used with a vaporising device. A typical well-known vaporising device
plugs into a power socket. Therefore, the apparatus may be provided with a
power socket in the first enclosure to enable a conventional vaporising device
to be simply plugged into the socket in the first enclosure.
BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention will be described with reference to
the following drawings in which :
Figure 1. Illustrates an apparatus for use with a mosquito coil/mosquito
Figure 2. Illustrates an apparatus for use with a plug in vaporiser.
Figure 3. Illustrates a further embodiment of the apparatus in the form of
a pressurised unit.
Figure 4. Illustrates a further embodiment of the apparatus containing a
Referring to the drawings and initially to figure 1 there is
illustrated an apparatus 10 which can better disperse a
repellent/fragrance/deodorising composition etc in a particular area. The
apparatus 10 is substantially box like and can have a length of between 20-60
cm, a width of between 10-40 cm and a height of between 10-30 cm. These
dimensions can of course vary to suit. The apparatus can be made of any
suitable material but it is preferred that the material is substantially waterproof
(to allow the apparatus to be used outdoors) and fireproof (to allow a
mosquito candle etc. to be placed in the apparatus). Thus, the material may
comprise metal, fibre cement and the like.
The apparatus has a top wall, a bottom wall, a rear wall, a pair
of closed sidewalls, and a front wall, these walls being substantially
continuous and attached to form a substantially enclosed container.
However, the front wall comprises a door 11. Door 11 is hinged at the top by
a horizontal hinge 12 which allows the door to naturally fall into a closed
position allowing the door to have a very simple yet effective design.
However, the door can also be hinged by a bottom hinge, a side hinge, can
be a sliding door, a clip on door or any other type of door.
The door forms one side of a first enclosure 13. The first
enclosure 13 is large enough to hold a mosquito coil/mosquito candle or any
other device which is to be placed within the first enclosure. The first
enclosure is defined by part of the top wail, part of the bottom wall, and part of
each side wall as well as the door 11. In the particular embodiment, the rear
wall does not form part of the first enclosure. Door 11 is provided with an
array of vent openings 14 to allow air to pass into the first enclosure. While
this is a simple arrangement, the invention is not to be limited to this particular
type of air inlet to the first enclosure.
The first enclosure 13 is also defined by an intermediate
partition wall 15. Wall 15 is provided with an opening which forms part of the
inlet to the fan enclosure 16. The partition wall 15 is spaced from rear wall 17
to form a second area 18 which is separated from the first enclosure 13.
The second area 18 contains the fan enclosure 16. The fan
enclosure 16 is a cylindrical shroud which passes about the fan. The
enclosure 16 has a fan inlet which extends into the first enclosure 13, and a
fan outlet which comprises a tapering tube 19 which tapers to an outlet 20
passing through a side wall of the container. The outlet 20 allows a flexible
perforated hose 21 to be attached to the outlet. The hose 21 can have any
suitable length and diameter and allows the exhaust from the fan (containing
the mosquito smoke etc) to be dispersed to any suitable area simply by
positioning the perforated hose in that area. This provides a
real and substantial advantage over other devices.
The fan can be powered either by a 12 volt power source
(typically a vehicle cigarette lighter) or by a transformer to
transform mains power into a lower voltage. In the embodiment, a
power socket 22 is provided on one side wall into which the
cigarette lighter attachment can plug or into which the
transformer can plug, providing versatility to the apparatus.
When camping, the apparatus can be placed next to a campsite
and can be powered by the cigarette lighter attachment in a
vehicle. The flexible hose 21 can be positioned around the area
which is to be protected. In a house, the apparatus can be placed
on the ground or anywhere else and the flexible hose can be
placed against the wall of the room as an extremely efficient and
effective deterrent. It is also found that use of the fan
provides better burning of a mosquito coil by providing a
continual draft of air to assist in the burning action. This
again adds to the efficiency of the apparatus.
Referring to figure 2, there is described an apparatus which
is similar to the apparatus of figure 1 except that one wall of
the first enclosure 13 is provided with a socket 29 to enable a
plug in vaporiser 26 to be simply plugged into the socket 26
inside enclosure 13. A fan 27 can then be operated to suck air
through the first enclosure in a manner similar to that described
above. In this arrangement and other compartment 28 is provided.
This compartment can contain the rear portion of socket 29 and
can be electrically insulated from the remainder of the
Referring to figure 3, there is illustrated a pressurised
unit. One advantage of this unit is that the smoke laden air does
not pass through the fan. The unit comprises a box like housing
3O. At the bottom of the housing is a fan 31. The fan 31 draws
air into housing 30 through a number of air inlet openings 32.
The openings 32 communicate with the outside of housing 30.
A mosquito coi1/candle/repellent 33 is positioned
above fan 31. This material is placed in a tray 34. The tray is
made of solid material and is positioned above fan 31. As the
fan blows air against the bottom of tray 34, the air passes
around the sides of the tray and towards outlet 39. During this
process, the smoke from the mosquito coil etc will be mixed with
the air such that smoke laden air will pass through outlet 39.Tray
34 prevents the coil etc from burning to quickly by preventing air
from blowing directly against the coil. The unit can also contain
a vaporising device (not illustrated) which can be plugged into
plug 36 and this can be connected to a source of electrical
power in a manner already described above which may include
mains power via a transformer 37 or battery power via a cigarette
lighter socket 38. Ofcourse, other types of power sources are
envisaged such as solar power etc. The outlet 35 communicates
with the perforated ducting 39 already described above which
allows the smoke laden air to be dispensed in any desirable
Figure 4 illustrates another variation which again has the
benefit of preventing smoke laden passing through the fan. This
variation can be seen as the "venturi variation". In this
variation, a venturi pipe 4O is provided, one end of which forms
the outlet 41. The perforated ducting 39 is connected to outlet
41 in a manner similar to that described above. The outher end of
the venturi has a flared opening 42. The fan 43 draws air in from
the outside of the unit through a fan housing 44 which has a
nozzle like outlet 45 which blows pressurized air into the flared
opening 42. By doing so* an area of low—pressure is created which
sucks adjacent air through venturi 4O. The adjacent air is the
smoke/vapor laden air inside the unit. The unit contains the
mosquito coil/candle or a vaporising device similar to that
described above. An advantage of this arrangement is that the
unit is not pressurized. Further inlet openings 43 are provided
in the vented door 46 to replace air which passes through the
venturi by virtue of the "venturi effect".
It should be appreciated that various other changes and
modifications can be made to any embodiment described without
departing from the spirit and scope of the invention.
