BACKGROUND OF THE INVENTION
Aroma emitting devices are well known and are commonly used in homes and commercial establishments to provide a pleasant atmosphere for people in given areas. Such devices passively or actively transmit aromas to the general surroundings. Examples of passive devices include air wicks, scented gel-packs, and aromatic sticks resting in a bottle of aromatic liquid and protruding out of the bottle so that the liquid is absorbed and drawn upward through the stick where upon, the liquid evaporates from the surface of the stick. One type of active aromatic device is plugged into an electrical power outlet, whereupon, a small heating element heats an aromatic liquid containing member thus causing the liquid to evaporate and escape into the adjacent surroundings. Another example of an active aromatic device is powered by battery or wall outlet and sprays an aromatic mist periodically into a room. Aromatic devices are commonly used by individuals who enjoy various selected scents. Further, the use of such aromatic devices has been found to improve or enhance the general demeanour of individuals in a particular surroundings. Certain scents have been found to cause desirable mood changes in people in general.
Devices that are only capable of dispensing a single scent suffer from the drawback that, after a relatively brief period of time, people become used to the scent and do not tend to notice it as much as when the device is first activated. In other words, "fragrance fatigue" can occur whereby a person's olfactory organ becomes "saturated" with a particular smell or fragrance and the individual becomes insensitive to the presence of the particular fragrance. Therefore, some efforts have been directed toward developing devices capable of emitting a single scent that address the problem of fragrance fatigue. Other efforts have been made to develop devices that are capable of emitting multiple scents. A number of patents have been directed to devices that are capable of emitting multiple scents.
Few conventional fragrance dispensers include basic components such as a motor for driving a fan, an electrical or mechanical power source for supplying power to the motor, and a fragrance source. These conventional fragrance dispensers however have several disadvantages. Some of the key drawbacks generally include an excessive number of components, which can make the device difficult and expensive to manufacture. Additionally, because of the excessive number of components, the odds of essential components being damaged or destroyed during use is increased, thus rendering the device inoperable. Because of design flaws, conventional fragrance dispensers can also be dangerous to operate as they may require the handling of corrosive components such as batteries, which may be corroded by, for example, interaction with the fragrance material or other such materials. Moreover, for the average consumer, conventional devices can be difficult to operate as they may require sophisticated assembly, disassembly and operation procedures.
WO2017062485A1 is a scent dispenser suitable for use in enclosed environments, for instance for use in vehicles. The scent dispenser includes a housing, a holder having a number of scent cartridge receivers to a hold a number of scent cartridges, and a number of baffles or shutters, each with a port, and which are selectively positionable with respect to respective ones of the scent cartridge receivers and, hence, with respect to the scent cartridges held by the scent cartridge receivers to selectively dispense scent from the scent cartridges. This invention lacks in achieving accurate dispensing of the fragrance in the fragrance system and further this invention does not provide a consumer with option of a customized fragrance as per choice of the user.
While conventional fragrance dispensing devices provide a means of automatically dispensing fragrance, such devices are often difficult to operate because of their design complexity. Such devices also do not adequately dispense fragrance over a large area. Moreover, such devices include multiple components that can be difficult to manufacture and assemble, thus making the device expensive and unreliable. Therefore, there is a need exists for an electronic multi fragrance dispenser through wireless communication that can be easily assembled, includes fewer parts, and it can be operated by the user in a highly convenient, simple manual fashion but that can also be provided with programming control, and that can be manufactured, and hence sold, at a low cost.
