Description

Fragrance emission control method and device
Technical Field
The invention belongs to the technical field of liquid aromatherapy, and particularly relates to an aromatherapy emission control method and device which can be used by a user according to the preference of the user, is convenient to carry and improve the use safety, and can be used interchangeably between home and vehicle.
Background
Along with the increasing requirements of people on life, the aromatherapy is gradually prevalent, and the common aromatherapy in some hotels generally comprises solid aromatherapy, liquid aromatherapy, aromatherapy candles and rattan aromatherapy.
The solid aromatherapy is generally wood, to which essential oils are added, having a pleasant smell. Wooden champignon can be put in the dish and put everywhere at home, and some also can light in the champignon dish, and taste is more strong like this. Different solid fragrances vary in size and, in general, may burn for more than ten minutes per ignition.
The liquid aromatherapy generally adopts extracted plant essential oil, has aromatic flavor and is easy to volatilize. The liquid fragrance can be put into the fragrance lamp for use, and as long as a proper amount of water and a few drops of liquid fragrance are added into the fragrance lamp, and the switch is turned on, the fragrance taste can be filled into the whole room for a while. Of course, the liquid aroma can be dripped into the bathtub when the user takes a bath, so that the dual relaxation of spirit and body is facilitated.
The scented candle is an art candle, which contains abundant essential oils in addition to wax, and thus, may release a fragrant smell when burned. The scented candle has beautiful shape and convenient use, thus being popular with people entering the scented candle.
The rattan champignon enables essential oil to be diffused into the air through mediums such as rattans and the like, fragrance can be continuously generated without using open fire, the rattans can be reused, and the effect that the essential oil is added regularly is good. The rattan aromatherapy modeling is various, and the rattan aromatherapy incense is safe and simple to use.
The use and the emission of the aromatherapy of any type are generally preset by hotel waiters, so that customers can smell the fragrance once entering a room, and the aim of relaxing both spirit and bodies is fulfilled. However, there is a great disadvantage in that it is not guaranteed that each customer likes the predetermined fragrance.
At present, the aromatherapy device mainly fills liquid perfume in a container such as a bottle or a tank, and releases the same perfume to the environment for a long time through natural evaporation or air pump atomization. People are easy to have olfactory fatigue in the same fragrance for a long time.
The solid aromatherapy and the liquid aromatherapy can be used interchangeably at home and on board; the liquid aroma generally appears in the form of vehicle-mounted perfume, the explosion accident of the perfume bottle easily appears in the use process, and the use safety is low. When the solid aromatherapy and the liquid aromatherapy are used as the household aromatherapy and the vehicle-mounted aromatherapy, the solid aromatherapy and the liquid aromatherapy need to be used for a relatively long time to replace other fragrant varieties.
