Generator for encapsulating a fluid within a bubble
Abstract
A generator for smoke and bubbles in combination includes a
storage chamber for a smoke forming fluid and a smoke generator for
creating smoke in a chimney. There is a bubble generator with a
nozzle for forming a fluid over the nozzle and smoke from the
chimney enters the bubble-forming fluid and exits the device such
that the smoke-filled bubbles are formed. Excess fluid and
condensed fluid, which would otherwise form smoke, is returned to
the storage chamber where heating of the fluid for forming the
smoke is effected in a tube where capillary action causes
smoke-generating fluid to be heated.

Description
BACKGROUND
[0001] This disclosure relates to a system for generating a gas and
bubbles and having bubbles encapsulating gas is formed and expelled
from the device. In particular the gas is a smoke.
[0002] Different devices are known for generating smoke in a toy.
Also, different devices are known for generating bubbles in a toy.
In some cases, it is known to have toys where smoke is encapsulated
in the bubbles and this is expelled from the toy. The features of
such a toy, however, are not as versatile and satisfactory as would
otherwise be possible.
[0003] It is accordingly an object of the present disclosure to
provide a system, device and method for creating smoke, creating
bubbles, and selectively having the smoke encapsulated in the
bubbles and expelled by the toy, which toy has improvements over
previously existing devices.
SUMMARY
[0004] A system, device and method for forming a gaseous substance
such as smoke from a gaseous-forming fluid. There is a storage
chamber for the gas creating fluid. A pump directs fluid through a
valve to a gas generator. The generator may include a tube for
generating capillary flow action of the gas creating fluid. A
heater associated with the tube causes vaporization and formation
of the gas in a chimney. Excess fluid from the generator and
condensed fluid from the chimney are directed through a return
chamber and a valve to the storage chamber.
[0005] A bubble generator which forms bubbles through a fluid at
the nozzle end at the outlet from the chimney is arranged so that
the gas formed in the chimney enters the bubble prior to formation
and the bubbles containing the gas are in turn expelled from the
front leading end or upstream side of the device.

DETAILED DESCRIPTION
[0013] The device is now described with reference to an example
which is not to be considered as limiting. This is purely an
illustration of the device, and it relates to the formation of
smoke or a or a colored gaseous material .
[0014] A generator for producing smoke and bubbles in combination
comprises a chamber for a substance capable of forming smoke when
the substance is heated. There is a pump for moving the substance
from the chamber to a smoke generator, and a heater heats the fluid
in the smoke generator. An outlet from the smoke generator direct
smoke towards a chimney and towards expulsion from the body via the
chimney.
[0015] A bubble generator forms bubbles, and the chimney directs
smoke from the chimney to join with the bubbles being formed and
thereby encapsulating smoke in the bubbles and releases the bubbles
containing smoke from the body.
[0016] The smoke generator includes a tube through which the
substance capable of forming smoke passes. The tube is heated so as
to heat the contents of the substance passing through the tube and
permit the forming of smoke through vaporization of the
substance.
[0017] There is a fluid path between the smoke generator and the
chamber for returning at least one of non-vaporized or condensed
fluid substance to the chamber.
[0018] The chamber includes two chamber sections, a storage chamber
and a return chamber connected with the storage chamber for the
fluid. There is a valve between the chambers, the valve being a
one-way valve permitting fluid to flow from the return chamber to
the storage chamber at a selected time. The return chamber receives
excess fluid from the smoke generator and condensed fluid from the
chimney.
[0019] An outlet valve is located between the chamber and the smoke
generator, the outlet valve being open during formation of smoke in
the smoke generator and being closed at selected other stages.
[0020] There is a pump for causing the smoke generating fluid to be
pumped from the storage chamber as a pressurized fluid to the smoke
generator. The pumping is effected through an outlet valve between
the storage chamber and the smoke generator. In that stage the
one-way valve between the return chamber and the storage chamber is
closed.
[0021] A device wherein the smoke generator includes a cylindrical
tube, and including a pin inside the tube thereby to affect a
capillary flow through the tube and regulate the amount of fluid
flow through the tube.
[0022] An electrical wire filament is located about the tube, and
the filament is for generating heat in the region of the tube when
power is applied to the electrical filament and wherein when the
temperature of the filament rises above a boiling point of fluid
passing through the tube the fluid inside vaporizes to generate
smoke.
[0023] There is a tube in the smoke generator, and a pin inside the
tube thereby to affect a capillary flow through the tube and
regulate the amount of fluid flow through the tube.
[0024] The bubble generator is located towards the downstream end
of the body, the downstream end being the downstream end of the
chimney. The bubble generator includes an aperture across which a
film of bubble-forming material is spread and wherein smoke from
the chimney is forced into engagement with the bubble-forming
material and the smoke from the chimney. This causes the bubble to
form with smoke therein and then be released with the bubble of the
film forming material from the body.
[0025] A fan urges the bubble-making film from a periphery about
the aperture and wherein the fan further urges smoke to enter the
bubble prior to forming the bubble, and the bubble leaving the
periphery. There is a tray located peripherally towards a forward
end of the body, and the tray is for receiving condensed fluid at
the forward end of the chimney. A fluid connector is placed between
the tray and the return chamber.
[0026] The bubble generator includes an element with fins splayed
radially about a central axis, there being spaces between adjacent
the fins for receiving bubble-forming material. The element with
fins is located in a nozzle area at the downstream end of the body.
The nozzle is mounted for articulation thereby to be dipped into a
container holding a bubbling forming solution and so as to permit
the spaces between the fins to receive the bubble-forming
solution.
[0027] A further description of the system is as follows
[0028] The smoke bubble generation system is a device that can
generate and blow out many smoke bubbles with different sizes. To
get more fun, bubbles can be kept on floating by blowing the bottom
of the bubbles through the nozzle of the device. When bubbles
burst, smoke comes out gradually.
[0029] The fluid chamber is used to store fog fluid. It includes a
chamber opening. Users can fill the fog fluid to storage chamber
through this opening. A pump inlet is connect to a gas or air pump
. There are two adjacent chambers-the storage chamber and the
return chamber with a one-way valve is located in between these two
chambers. The valve functions to prevent the fluid flowing from the
storage chamber to the return chamber.
[0030] A fluid inlet permits excess or condensed fluid at smoke
generator to flow back to the return chamber. A fluid outlet
permits the injection of the fluid to the smoke generator through
the outlet valve
[0031] The system for encapsulating a first fluid within a bubble
is disclosed. The system generates smoke and bubbles, and is in the
nature of a handheld toy, which includes a body 10. There is a
handholding area 11 at the downstream end of the toy, and there is
a leading or forward area 12 with an intermediate area 13 between
the portions 11 and 12. In one preferred form, the toy is intended
to be used in a more vertical orientation, although different
orientations are possible. On the outside of the body there is a
heater switch 14.
[0032] There is also a pair of depressible buttons 15 and 16. The
button 15 is a fan speed control to permit for the creation of
larger bubbles and the button 16 is a fan speed control to permit
for the creation of smaller bubbles. In the rear area 17 of the
rear hand holding area 11 of the body 10, there is a battery
compartment 18 for housing batteries 19, 20 and 21. The batteries
are wired through wires 22 with an air pump 23. The air pump 23 is
itself controlled by the trigger buttons 15 and 16 so that, when
depressed, a circuit can close to regulate the particular speed of
the air pump 23. The circuit with the batteries in the battery
compartment is effectively closed electrically in a conventional
manner.
[0033] There is also wiring 24 which is directed past the mid
intermediate area 13 to a heated smoke generator 25. There is a
printed circuit board 26 which operates a system with the heater in
a manner that is more fully described below.
[0034] In the midsection 13 of the device, there is a chamber
configuration which has a first storage chamber 28 for storing a
first fluid substance which is capable of forming smoke. There is a
return chamber 29 for receiving fluid returned from a chimney area
30 in the leading portion 12 of the toy.
[0035] The wiring 31 is also directed to a motor 32 for a fan 33
which is located at the leading end of the forward portion 12. At
the leading end 34 a saucer, plate or tray 35 is mounted below a
nozzle 36 which is spaced above the tray 35. The nozzle 36 may be
moveable in a hinged or articulated manner about the mounting 37 to
adopt a substantially right angular position relative to the
longitudinal access running through the device. In this manner, the
nozzle 36 can dip into a bubble-making solution in a manner to be
described in further detail below.
[0036] Between the storage chamber 28 and the return chamber 29
there is a one-way valve. Operation of the air pump 23 acts to
apply pressure in chamber 28 which then causes fluid in the storage
chamber 28 to exit from the chamber along the outlet line or tube
37. In the outlet line or tube 37 there is a metal pin 38 which is
located in the line or tube 37. The line or tube is essentially
formed by a glass tube. Around the glass tube 39, and connected
with a circuit board 26, there is a spiral wired heater which acts
to heat liquid or the first substance passing through the aperture
40 under capillary action. The exit 41 from the glass tube 39
causes vaporized fluid to enter the chimney area 30 of the
device.
[0037] The vaporized fluid is in the form of smoke and this can be
visualized through a window 42 in the body 10 of the leading
portion 12 of the device. Excess fluid from the smoke generator
returns to the return chamber 29 as figuratively indicated by arrow
43. Further condensed fluid from the chimney area 30 returns to the
return chamber 29 as figuratively indicated by arrow 44. When the
air pump 23 is switched off, fluid from the return chamber 29 can
pass through a valve 45 from the return chamber as indicated by
arrow 45 back to the storage chamber 28. At that stage, a valve 46
at the outlet of the storage chamber is closed.
[0038] At the forward end, nozzle 36 can be dipped into a
bubble-forming solution 47 as indicated by the dotted lines 48. The
nozzle 36 is then returned to its position in alignment with the
chimney.
[0039] Smoke from the chimney 30 is drawn to the exit 34 when the
fan 33 operates. At the same time, the fan 33 causes a film on the
nozzle 36 to expand to form a bubble. In this process, the smoke
from the chimney is encapsulated in the bubble 49.
[0040] The nozzle 36 includes a series of radial fins 50 mounted on
a plate 51. The fins 50 have spaces 52 between them to permit for a
bubble-forming solution to be located between the fins. The fins 50
are directed outwardly from the end and also inwardly towards the
end as two separate sets so that sufficient fluid is located around
the nozzle 36. This permits for the bubble-making solution to be
effectively disbursed around the periphery and over a central
orifice 53 around the nozzle. In the chimney there is located a
heater light 50 which operates when the heater is working as
powered through the circuit board and the battery pack.
[0041] The operation of the device is as follows.
[0042] By pressing the fluid pump manually, pressure is exerted to
the chamber. The positive air pressure opens the outlet valve and
closes the one-way valve essentially at the same time. With the
flow rate control mechanism, a small amount of pressurized fog
fluid passes through the outlet valve and is injected to the smoke
generator. The capillary effect inside the tube permits the fluid
to flow continuously.
[0043] When releasing the pump, the negative air pressure closes
the outlet valve and the one-way valve allows a little excess fluid
flowing from return chamber back to storage chamber for re-use
purpose.
[0044] The smoke generator includes a cylindrical glass tube with a
metal pin inside the tube and wound wire filament outside the tube.
This generator is mounted directly on the fluid chamber's
outlet.
[0045] After turning on the `Heat` switch, an electric current
passes through the wire filament and generates heat. A LED lights
up to indicate this generator is in operation. Since the space
between the metal pin and glass tube is small, only a limited
amount of fluid can flow through it. To produce high temperature
zone, this is effected by applying high heating power in this
region.
[0046] Once the temperature of filament rises over the boiling
point of fluid, the fluid inside the high temperature zone
vaporizes immediately and generate a lot of smoke. The chimney
becomes smoke-filled. Excess non-vaporized or condensed fluid will
be collected and return to chamber through the fluid inlet.
[0047] Formation of bubbles is achieved by a bubble generator that
can generate soap bubble. After dipping the open aperture of
chimney to a soap solution, liquid film is formed on its surface.
There is a small electric fan near the open aperture. Pressing the
Hi/Lo speed control to adjust speed of fan and hence product
different sizes of bubble. If the chimney is full of smoke, smoked
bubble is blown.
[0048] Generating a smoke containing bubble is achieved by
operating the bubble generator and smoke generator at the same
time. Furthermore, by switching on the fan and turning off the
smoke generator, a user is able to hold the bubble floating on
air.
[0049] Should a user forget to switch off the smoke generator after
playing, and if there is no fluid inject to it, over-boiled may
result. A built-in electronic timer cut-offs the power of smoke
generator automatically if no pumping fluid action take place
within certain period of time.
[0050] While the apparatus and method has been described in terms
of what is presently considered to be the most practical and
preferred embodiments, it is to be understood that the disclosure
need not be limited to the disclosed embodiments. It is intended to
cover various modifications and similar arrangements included
within the spirit and scope of the claims, the scope of which
should be accorded the broadest interpretation so as to encompass
all such modifications and similar structures.
[0051] In different variations of the disclosure the bubble can be
formed of a fluid other than soap. Also the smoke may be formed by
different fluids other than oil so that the smoke color is not a
pale grey color. There could be more than one fluid and more than
one storage chamber provided so that the colors of the smoke can be
different. Furthermore instead of the stick type shape there can be
different shapes and sizes for the device Moreover the device can
be operated with power adaptor instead of being battery-operated.
The bubble generator can be operated manually instead of by
electric fan. Instead of heated smoke there can be a mist, water
vapor, or colored liquid vapor, gas other than smoke particle. The
gas may be relatively lighter than the surrounding air and this can
cause the bubble encapsulating the gas to effectively float or rise
above gravity.
[0052] The present invention is not limited to the embodiments
described above, but includes any and all embodiments of the
following claims.
