The direction of the second mixing of the present invention is preferably consistent with the first mixing to avoid turbidity and precipitation.

[0052] In the present invention, the temperature of the purified water is preferably 15 to 20°C, more preferably 16 to 18°C.

[0053] After obtaining the essential oil fragrance, the present invention preferably filters the essential oil fragrance and puts it into a spray bottle to obtain a spray of the essential oil fragrance.

[0054] The preparation method provided by the invention can obtain a wood lotus odor characteristic with a Zen style, which can make people feel peaceful, calm and self-cultivating. The preparation raw materials do not contain alcohol, and compared with traditional fragrances, the essential oil fragrance is safer and will not irritate the skin. The essential oil fragrance is transparent in color, and the color will not deepen when placed under the conditions of 5-10°C, 16-21°C or 38-40°C, and no precipitation will be generated, and the stability is good.

[0055] The present invention also provides the application of the essential oil fragrance described in the above technical solution to enhance the visiting experience in the exhibition. When visiting an exhibition, especially a cultural relic exhibition, the essential oil fragrance provided by the present invention can be used as an atmosphere source to create a smell that matches the exhibition content. At the same time, this influence can act on the human brain's limbic system, affect emotions and memory, and add smell to the traditional hearing and seeing of the visit, expanding the auditory and visual visit to hearing, vision and smell, and producing a synesthesia effect, which makes people have different emotional characteristics and has a profound impact on the senses, pleasure, human memory and emotions.
