DEVICE FOR WARNING A CAR DRIVER ABOUT A PRE-EMERGENCY SITUATION

摘要

The invention relates to devices for forming flavouring airflows, which are mounted on vehicles for warning drivers about possible hazardous situations. The inventive device for an aromatic gas medium, which can be used in the form of a device for warning a car driver about a pre-emergency situation, comprises a chamber for mixing the gas medium with adorant vapours, which is provided with input and output sleeves, at least one adorant metering unit which is connected to the mixing chamber and comprises a container for the liquid adorant and a recipient provided with at least one through jet nozzle whose output is arranged in the mixing chamber and actuating elements for producing pressure pulses in the recipient which are fixed to the recipient wall on the inner side thereof and connected to a power supply, a unit for controlling the device operation and a gas medium flow booster provided with a control unit. Said invention makes it possible to develop a complex range of odours each of which individually characterises different hazardous situations and to ensure a high reaction of a flavour synthesiser to a signal transmitted by a vehicle computer control system.
