Definitions

• the invention relates to a device for nebulizing rooms and is to be used in particular to take burglars in closed rooms and to panic them so that they are dissuaded from your intention to steal objects.
• Devices of this type can be drawn by a conventional alarm system or other suitable means. With the triggering of the device, further alarm systems can of course be put into operation, so that the owner or, if necessary, the police can take further countermeasures against the burglar or burglars.
• Such a device is known from DE-Al-43 28 697.
• This system has a distributor that explosively distributes fog that obstructs vision.
• Known components such as those used in fog grenades, can be used as the basis for generating the fog. Of course, it is assumed that these agents are non-toxic, so that damage to health can be excluded.
• the invention has for its object to provide a simply constructed device that is essentially independent of a power supply and for triggering, for example can easily be connected to an existing alarm system.
• the essential idea of the invention is therefore to design the active parts of the device which are essential for the nebulization as pyrotechnic sets which can be activated independently of an energy supply. All that needs to be activated is a small squib, for the supply of which a small battery or the connection to the sensor system of an alarm device is sufficient.
• the pressure which arises when the mixture is heated and evaporated to generate the mist may be sufficient to flow the mist out of the container through an opening with a valve.
• a further pyrotechnic pressure set in the container, which is ignited synchronously with or later than the heating set and which develops propellant gases when it burns. These propellant gases flow into the container via a connection, where they generate the pressure sufficient for the mist to flow out.
• the pressure set can be accommodated in the same housing as the heating set or integrated in it. This pressure set is also preferably a pyrotechnic set.
• FIG. 1 shows a longitudinal section through a device for atomizing rooms according to the invention.
• an apparatus 1 for atomizing rooms has an outer housing 2, in which a container 3 for receiving a fog fluid 4 is mounted.
• This fog fluid 4 is, for example, a mixture of water and glycol and in this case fills the container up to half.
• a channel 5 leads from the container in the fluid-free space and is closed in the container by a rupture disk 6. This channel also penetrates the housing 2 and opens outside the housing 2 in a nozzle 7.
• a pyrotechnic heating cartridge 8 protrudes into the fog fluid 4, which has a heating element 9 and a pyrotechnic primer 10, which are accommodated in a solid gas and pressure-tight jacket 11.
• the pyrotechnic squib 10 may e.g. are ignited electrically via a cable 12, which leads from the squib 10 to a sensor system and energy supply 13.
• a pressure cartridge 14 protrudes into the fluid-free space of the container 3 and has a pressure set 15 and a pyrotechnic squib 16 which are accommodated in a container 17.
• the pyrotechnic squib 16 may e.g. are in turn electrically ignited via a cable 18 which leads from the squib to the sensor system and energy supply 13.
• the sensors and power supply 13 receive e.g. an activation signal from an alarm system if a break-in has been detected.
• the sensors and power supply 13 can e.g. receive a small electric battery and logic that controls the operation of the device. The function is as follows:
• an electrical pulse is sent via the cable 12 to the pyrotechnic squib 10 of the pyrotechnic heating cartridge 8. This ignites the heating element, which is relatively quick burns. Via the jacket 11, the heat generated during the combustion is released to the fog fluid 4, which is thereby heated and evaporated very quickly. As soon as the vapor pressure inside the container is large enough, the rupture disk 6 is destroyed, so that the mists of smoke emerge via the channel 5 and the nozzle 7 and quickly fog up the space to be protected.
• the pyrotechnic squib 10 is either used at the same time or is decelerated - depending on that required for the evaporation of the mist fluid 4
• Time period - the pyrotechnic squib 16 of the pressure set 15 ignited.
• the outer wall of the print cartridge 14 is destroyed during ignition, so that the propellant gases released when the pressure set 15 burns off are released into the container 13. In this, the internal pressure rises accordingly, so that the rupture disk 6 is destroyed and the vaporized fog fluid is expelled.
• a fog fluid 4 is filled in the container 3; there are also a plurality of pyrotechnic heating cartridges 8, in this case four cartridges. However, one of these cartridges can also be a print cartridge. It is also possible that the individual heating cartridges have both a pyrotechnic heating element 9 and a pressure element 15, as is shown schematically in FIG. 3.
• the heating cartridge 9 is in turn encapsulated by a jacket 11, so that no gases escape to the outside when the heating element burns up.
• the two sets are preferably ignited one after the other, the heating set 15 only being ignited when the fog fluid 4 is already in vapor form.
• the advantages of the devices described compared to conventional methods include the ability to function extremely quickly after the draw, whereby, depending on the design, the fog can be released within a period of between 3 and 20 seconds. No pyrotechnic gases or smoke escapes, since normal fog fluid, as is also used in electric fog machines, is used in this device.
• the device is inexpensive to manufacture, since the structure is very simple compared to other electrical devices used, for example, in stage shows, etc.
• Another advantage is that after the device is activated, its function can no longer be stopped, ie there is an autonomous mode of operation.
• the device is very easy to connect to any alarm system. It is also easy to maintain because there are no wearing parts. Uncomplicated technology guarantees a reliable way of working. The device can be used even under extreme conditions, for example in heavily soiled rooms, and is insensitive to heat and cold.
