Definitions

  • the invention relates to a "fog generator according to the preamble of claim 1.
  • Such mist generators generate mist-like aerosols by atomizing a liquid that is present at the same time in a cloud chamber filled with air by means of several ultrasound sources.
  • These devices can be used in discotheques, theaters, bars and on stages, among other things, to create or enhance optical effects.
  • mist generators for producing mist-like aerosols either immerse pieces of dry ice in hot water, or evaporate aliphatic oils by heating and then quickly condense by mixing with cold air.
  • a third method instead of the aliphatic oils, an aqueous, hygroscopic solution is evaporated and condensed (German Offenlegungsschrift DE 3126952 A1).
  • the invention has for its object to provide a fog generator that generates large amounts of fog immediately after switching on, this fog must not contain any harmful substances, is not flammable and does not condense on objects in the vicinity of the generator.
  • a plurality of ultrasonic transducers which are operated simultaneously, are preferably arranged in a common cloud chamber.
  • the fog generator according to the invention enables a very large amount of atomized liquid to be produced immediately after the generator is switched on, since the ultrasound-emitting devices do not require lengthy heating-up or cooling-down processes for their operation and are only dependent on electrical energy, air and fog liquid.
  • the ultrasonic atomization causes the formation of a relatively monodisperse aerosol, which naturally shows only a slight tendency to condense on objects in the vicinity of the generator.
  • the fog generator according to the invention has, in particular, considerable advantages over other known devices which require long heating phases, produce oily or aqueous condensate residues or produce flammable and / or harmful aerosols.
  • a particularly advantageous embodiment of the invention for generating the ultrasonic vibrations consists in the fact that only one high-frequency generator supplies several ultrasonic transducers.
  • the high-frequency generator can consist of a clock generator and several power output stages, each output stage being assigned to at least one ultrasound transducer.
  • This embodiment has the advantage that the generator works with only one ultrasound frequency and that undesirable influences on the ultrasound transducers are avoided. At the same time, radio interference suppression that is necessary in any case is considerably simplified.
  • each ultrasound transducer is assigned its own high-frequency generator. With this arrangement it is achieved that each ultrasonic transducer works independently and with optimal performance, and that the rest remain functional in the event of an electrical fault in a high-frequency generator. In addition, these high-frequency generators only need to generate a relatively low RF power, so that inexpensive electronic assemblies can be used here.
  • the ultrasonic transducers are attached to the bottom of the fog chamber by elastic parts. With this arrangement it is achieved that the ultrasonic transducers are only slightly damped by their holder and that only a small part of their vibration energy reaches the bottom of the fog chamber. As a result, the generated ultrasound energy can be transferred to the liquid without great losses, so that the generator is effective. At the same time, the elastic parts prevent liquid from leaking out of the cloud chamber due to their sealing function.
  • a particularly advantageous embodiment of the invention integrates the ultrasound transducers into a housing enclosing the high-frequency generator part, the sound-emitting surfaces of the ultrasound transducers being arranged in corresponding openings in the upper part of the high-frequency generator housing.
  • this wall of the housing is also part of the bottom of the cloud chamber, and the surfaces of the ultrasonic transducers can thus subject the liquid which is always present in the cloud chamber to high-frequency vibrations.
  • the housing walls of the high-frequency generators from good electrically conductive material, preferably aluminum, for the purpose of good electrical radio interference suppression.
  • Aluminum is particularly suitable here, since it is relatively inexpensive, easy to process and has good electrical and thermal conductivity.
  • the liquid height above the ultrasound-emitting surfaces of the ultrasound transducers is constantly adjusted to at least 0.1 mm during operation by suitable control devices which act on the liquid pump.
  • suitable control devices can be, for example, sensors, light barriers or switches triggered by floats, which act directly or indirectly on the liquid pump, and thus adjust the liquid level in the cloud chamber such that the above-mentioned. Condition is met. This ensures that there is always enough liquid available for atomization, and that the ultrasonic transducers run dry and thus avoid damage to them.
  • the bottom of the fog chamber is designed as a collecting container for the liquid to be atomized and opens into a liquid channel at the lowest point.
  • a further advantageous embodiment of the invention consists in preferably using a self-priming liquid pump as the pump of the generator.
  • a self-priming liquid pump as the pump of the generator.
  • an easily transportable and refillable external tank can be used as the liquid supply, which is connected to the pump on the suction side via a corresponding liquid channel.
  • a filter is attached to at least one point in the liquid channel, preferably at the end that lies outside the generator housing.
  • This filter can e.g. be designed as an immersion filter, which is inserted into an external tank and prevents contaminants from entering the liquid channels, the pump or the cloud chamber. This avoids unnecessary contamination of the cloud chamber and, at the same time, potential causes of faults.
  • the ultrasonic transducers In order to avoid the destruction of the ultrasonic transducers by running dry, it is expedient, according to a further embodiment of the invention, to install at least one sensor in the fog chamber which switches off at least a part of the fog generator, in particular the high-frequency generator or generators, when the liquid level falls below a predetermined level.
  • This sensor can consist, for example, of a light barrier or a float switch which, when the liquid level drops in the fog chamber below a minimum height interrupts the power supply to the electrical components.
  • the same sensor simultaneously triggers at least one optical and / or acoustic signal in addition to switching off electrical components. This alerts the user of the fog generator to a malfunction and e.g. prompted to refill the external liquid tank.
  • a droplet separator is located in the interior of the fog generator, which removes entrained liquid splashes and coarser fog droplets from the aerosol.
  • the droplet separator is expediently attached between the fog chamber and the discharge shaft, so that the air flow generated by the blower transports the aerosol generated in the fog chamber through the droplet separator before the aerosol leaves the generator.
  • Another possibility is to integrate the droplet separator into the discharge duct.
  • this arrangement according to the invention it is achieved that only a small and therefore inexpensive droplet separator is required, since already on the way that the aerosol travels from the cloud chamber to the blow-out shaft, a part of the entrained liquid particles in the fog generator to the Is deposited on the walls.
  • the bottom of the droplet separator has a slight slope in the direction of the outlet of the cloud chamber, so that the separated liquid flows back to the cloud chamber and is atomized again there.
  • the obstacles of the droplet separator deflecting the aerosol are designed according to the invention in such a way that they enable the separated fog liquid to return to the fog chamber, preferably through appropriate bores. It is also possible to remove the obstacles from the droplet separator inside the generator e.g. to be attached to the side walls in such a way that a free gap remains at the bottom of the separator through which the liquid can flow back to the cloud chamber.
  • the bottom of the blow-out shaft has a slight slope in the direction of the cloud chamber, so that condensing liquid in the blow-out shaft flows back to the cloud chamber and does not drip out of the generator, as is often the case with conventional generators.
  • the liquid flowing back can be atomized again.
  • dust filters are arranged in the area of the air inlet openings of the blowers. This prevents dust or dirt particles from getting into the generator and in particular into the fog chamber, otherwise the function of the ultrasonic transducers or the sensors for controlling and monitoring the liquid level could be impaired.
  • These dust filters can expediently be designed as paper or plastic filter inserts that are easy to change from the outside, so that they are regular can be exchanged.
  • the outlet openings of the air flow for cooling the electrical components in the interior of the mist generator are preferably arranged at right angles to the outlet shaft of the aerosol. This ensures that the air flow heated by the electrical parts of the generator does not mix with the aerosol, since this would impair the life of the aerosol.
  • mist generator for generating liquid mist by means of several ultrasound sources from a mist chamber 1, the lower wall 17 of which is designed as a collecting container for the liquid 7 to be atomized. and which has at its lowest point an outlet 18 which opens into the liquid channel 4.
  • the liquid channel 4 is connected to the pump 3, which pumps the liquid to be atomized from an external liquid tank into the fog chamber 1 via the liquid channel 5 and liquid filter 19.
  • the external tank is not shown for the sake of simplicity.
  • the liquid channel 5 breaks through an outer wall of the mist generator (not shown) and preferably has a filter 19 at the end Liquid channel 5 can be pumped into the cloud chamber 1.
  • the bottom 17 of the fog chamber 1 is designed in such a way that there are openings at several points, in which the ultrasonic transducers 6 are installed by means of suitable elastic connecting parts 12.
  • the elastic parts 12 simultaneously seal the bottom 17 against the ultrasonic transducer surfaces 15, so that no liquid 7 can escape here.
  • the surfaces 15 of the ultrasonic transducers 6 are arranged such that they are constantly wetted by the liquid 7 and to the stationary liquid surface 16 are aligned in parallel.
  • the sound-emitting surfaces 15 are preferably arranged horizontally, while the fog chamber floor 17 has a slight slope in the direction of the outlet 18.
  • two sensors 20 and 21 are located in the fog chamber 1, for example on a side wall of the fog generator.
  • the sensor 20 serves to control the pump 3 in order to regulate the level of the liquid 7 in the fog chamber 1.
  • the sensor 21 switches off the high-frequency generators 11 and at the same time triggers the optical or acoustic signal transmitters 22 and 23.
  • the air mixes in the cloud chamber 1 with the liquid 7 atomized by the ultrasonic transducers 6, an aerosol being formed which, when flowing through the droplet separator 24, is freed of coarse droplets and liquid splashes at its obstacles 26, 27, 28 and then the fog generator through the exhaust duct 2.
  • the bottom 25 of the droplet separator 24 and the bottom 29 of the blow-out chute 2 have a slight slope in the direction of the fog chamber 1, so that separated liquid can flow back to the fog chamber 1.
  • the obstacle 27 of the droplet separator 24 is provided with holes 33 to allow the liquid to return.
  • a second fan 9 is arranged in the lower part of the fog generator, which draws in fresh air through a dust filter 31 and through openings in the rear wall of the fog generator, which is used to cool the electrical components, in particular the high-frequency generators 11, the ultrasonic transducers 6 and pump 3.
  • the air flow heated in the process leaves the generator through the outlet openings 32 arranged in the side walls.
  • the high-frequency generators 11 work simultaneously in the operating state and supply the ultrasonic transducers 6 with high-frequency alternating current.
  • the ultrasonic transducers 6 convert this alternating current into mechanical vibrations, which are transmitted from the sound-emitting surfaces 15 to the liquid 7. Due to the effect of the ultrasonic vibrations, the liquid 7 is atomized into the finest droplets on the surface 16.
  • the liquid droplets mix in the cloud chamber 1 with the air which is always present there.
  • the resulting aerosol is transported by the air flow that the blower 8 generates after passing through the droplet separator 24 through the blowout duct 2 from the mist generator.
  • the liquid mist emerging from the discharge shaft 2 can be used for commercial purposes, in particular for displaying and / or enhancing optical effects.
  • Fig. 2 shows a schematic representation of an embodiment in which the fog chamber floor 17 is also a wall of the high-frequency generator 13.
  • the ultrasonic transducers are accommodated in the housing 14 in such a way that the sound-emitting surfaces 15 are located in corresponding recesses in the bottom of the cloud chamber 17.
  • the sound-emitting parts of the ultrasonic transducers are held and sealed by elastic parts 12.
  • the elastic parts 12 prevent liquid from penetrating into the high-frequency generator 13 and that the ultrasonic energy is dissipated into the cloud chamber floor 17.
  • the interior of the housing 14 also contains the ultrasound transducers (not shown) with their sound-emitting surfaces 15, which convert the alternating electrical currents into mechanical vibrations.
  • the invention further relates to a method for generating an effect mist according to the preamble of the main claim.
  • Effect nebulae are preferably generated in discotheques, theaters, film and television studios in order to improve the lighting effects in such rooms or to achieve certain mood effects.
  • the invention has for its object to provide a method for generating an effect fog, with which a better stabilized fog than the previously known possibilities can be generated.
  • This object on which the invention is based is achieved in that a further fog generator is assigned to the fog generator working with an oil or glycol water-based fog liquid, which creates a fog-like aerosol based on air-water and possibly carbon dioxide, the two fog generated in this way introduced into each other, mixed and depending on the desired effect, the two types of fog can be dosed.
  • a substantially more stable fog is achieved, and surprisingly it is additionally achieved that a fog is created which can be adjusted according to its chosen mixing ratio at any altitude on the stage or in the room, i.e. can be stabilized.
  • the fog generated in this way may be less water and therefore no longer has the disadvantages of pure dry ice fog generators.
  • the method according to the invention achieves that the fog is generated both on the top and bottom of a stage, that is, it can be present including all intermediate layers, so that it can meet the wishes of practice in full, which was previously not possible and which was perceived as a serious disadvantage, but was accepted.
  • the ultrasonic atomization causes the formation of a relatively monodisperse aerosol, which naturally shows only a slight tendency to condense on objects in the vicinity of the generator.
  • the two fog generators can be operated independently of one another, so that all mixing effects are possible. It is proposed that the two fog generators are combined in a single generator unit, so that a device is created with which all effects can be achieved, namely on the one hand the desired ground fog, on the other hand the desired high fog and finally by mixing the two, the desired stabilization of the Fog and the desired intermediate height of the generated fog.
