Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and particularly relates to a fan with an aromatherapy function. Background Art

[0002] The weather is hot in summer, and people tend to feel irritable and tired in high temperature environments. Fans are one of the home appliances that people use to keep cool. In high temperature environments, the air is hot and humid, and the surrounding environment is prone to produce odors. At the same time, mosquitoes will breed, bite the skin of people and animals, and cause trouble to people. Therefore, people will add aromatherapy functions when designing fans to refresh themselves and repel mosquitoes.

[0003] In traditional designs, the principle of adding an aromatherapy function to a fan is to install an aromatherapy component on the fan, and the aroma emitted by the aromatherapy component is blown through the fan, so that the aroma particles are diffused in the environment to purify the air. At present, a receiving slot is usually set on the front cover of the fan to accommodate the aromatherapy component, and the aromatherapy sheet on the fan cover is located in the air outlet direction of the fan, wherein a vent is provided on the outside of the front cover of the fan at the position of the aromatherapy component. The aroma of the aromatherapy component evaporates outward through the vent and then blows toward the user through the fan blades. Since the air outlet direction of the fan is usually at a lower temperature, the aromatherapy component evaporates slowly and has a small air outlet area, so that the user feels that the smell is thin, resulting in a poor aromatherapy effect.
