Description

Easy Diffusion Diffuser

technical field

Along with improving constantly of people's living standard, the activity that people participate in is also more and more, yet a lot of activity places, as: hotel etc., if the air is not fresh, can make the unpleasant mood such as tired easily, irritated. In order to create a better environment, people generally adopt methods such as using solid essence and spraying perfume in the room to improve the air quality in the room, so as to keep the air in the room fresh, eliminate peculiar smell and sterilize. . However, as far as the former is concerned, the fragrance of the solid essence cannot be emitted completely, which often causes a certain waste. The latter is cumbersome in the process of use, and because the sprayed perfume particles are relatively large, the range that can drift is very small, so the efficiency of this method is also very low.

The aroma diffuser is used to atomize the essential oil to diffuse the aroma into the air to improve the quality of the air.
