Description

Technical Field

[0002] With the improvement of people's quality of life, in some places with strong odors, such as cars, elevators or new houses, these places will have some odors more or less, and aromatherapy devices are usually used to purify the air to improve comfort. In view of this, many aromatherapy products have appeared on the market to improve the in-car environment, but most of them use aromatherapy and compound essential oils to improve the in-car environment air through natural evaporation. The aromatherapy products that rely on natural evaporation have a relatively slow evaporation speed, and the odor is relatively strong. There is no difference in feeling after using the aromatherapy products, and the practicality and fragrance uniformity are relatively poor. In addition, the existing aromatherapy machines have a single function, which mainly plays the role of fragrance dispersion.

[0003] The appearance and structure of existing aromatherapy products are single and solid, that is, the appearance is not novel enough, and the practicality and ornamental value are also poor. They are generally cylindrical, and a number of small circular fragrance holes are set on the top. This structure will affect the air flow inside and outside the aromatherapy machine and the effect of dispersing fragrance to the surroundings is poor; secondly, in order to increase the aesthetics, there is also a way of setting a decorative shell on the outside of the aromatherapy machine, but the added decorative shell will increase the wall thickness of the entire shell, generally more than 3mm, resulting in the internal charging interface being relatively far away from the external socket.
