Technical Field

[0001] This utility model relates to the field of nursing product technology, and in particular to an aromatherapy comb. Background Technology

[0002] With the increasing demand for personal care and a healthy lifestyle, multifunctional hair care tools are gaining popularity in the market. As a daily hair care tool, the comb's function is no longer limited to simply combing hair, but is gradually evolving towards diversified directions such as hair care, relaxation, and more. Aromatherapy, with its effects of soothing emotions and promoting scalp health, is widely used in the field of personal care. Therefore, combining aromatherapy functions with traditional combs represents a promising direction for product innovation.

[0003] Currently, there are some combs on the market with aromatherapy functions, but their designs often have the following technical flaws:

[0004] Low essential oil atomization efficiency: Traditional aromatherapy combs often release essential oils through passive evaporation or simple heating, resulting in poor atomization and uneven fragrance diffusion, leading to a poor user experience.

[0005] Insufficient airflow control: The atomized essential oil gas lacks effective guidance, which may cause the aroma to dissipate or the local concentration to be too high, affecting the effect of use.

[0006] Therefore, there is an urgent need for an aromatherapy comb that integrates efficient atomization and precise airflow control to improve user experience and broaden application scenarios. Utility Model Content
