The essential oil particles prepared by the invention are wide in application, can be applied to electronic cigarettes, indoor aromatherapy equipment, sachets and the like, and can control essential oil to release slowly and uniformly within a temperature range of 200 ℃ so as to avoid uneven phenomena of heavy fragrance before heavy fragrance, light fragrance after light fragrance and the like, thereby improving the user experience.
The invention also provides a filter tip which comprises an outer tube and an inner core arranged in the outer tube, wherein the inner core is filled with essential oil particles, and the essential oil particles are prepared by the preparation method of the essential oil particles.
The filter can be used as a filter of a traditional cigarette and a heating non-combustion electronic cigarette. When the essential oil granule is filled in the inner core, the essential oil granule is in the one end that the electron flue gas got into the filter tip, and the fragrance that the essential oil granule distributes like this can the flue gas flow out together to promote user's smoking experience.
In the embodiment of the invention, in order to avoid the essential oil particles from flowing out along with the smoke to reduce the smoking experience of the user, optionally, a filter membrane is arranged at one end of the outer tube, where the electronic smoke enters the filter tip, and the filter membrane blocks the outer tube to avoid the essential oil particles from flowing out along with the smoke. The filter membrane is a breathable paper film, can effectively block essential oil particles, and is low in cost.
Further, the inner core still includes the filter pulp, and the filter pulp is located the outer tube and is kept away from one side of filter membrane to and filter membrane between form the cavity, essential oil granule is filled in the cavity. The filter cotton is used for adsorbing and intercepting tobacco tar carried in smoke, plays roles of filtering and cooling, and essential oil particles are filled in the upstream of the filter cotton along the smoke flowing direction during assembly. So setting, when the user suction, the flue gas at first sees through in the filter membrane gets into the cavity, and the fragrance that essential oil granule distributed out in the cavity flows out along with the flue gas, and the flow-through process filter pulp flows out after filtering and cooling through the filter pulp to promote user's suction and experience.
It should be noted that the filter cotton can be selected from polylactic acid cotton, and the polylactic acid cotton can adsorb and retain the tobacco tar carried in the flue gas, so as to perform the functions of filtering and cooling.
Of course, in other embodiments, the structural arrangement of the inner core may also be other structures, which are not limited herein, and it is within the scope of the present invention that the hovenia dulcis thunb extract is filled in the inner core.
The invention also provides an electronic cigarette which comprises the filter tip. In use, the filter and the tobacco rod are assembled to form the electronic cigarette for a user to smoke.
In addition, the essential oil particles can also be used for preparing electronic cigarette oil, namely the essential oil particles are added into an electronic cigarette cartridge to be mixed with glycol, glycerol and nicotine, and the electronic cigarette oil can be obtained after mixing. Because the essential oil particles contain the boron element, the boron element of the essential oil particles can not flow out along with the release of smoke, and the essential oil particles also have an adsorption effect on the polyhydric alcohol in steam, so that the absorption of the polyhydric alcohol (such as propylene glycol and glycerin) by a human body is reduced.
