Description

Technical Field

[0001] This disclosure relates to the field of aroma diffuser technology, and more particularly to an aroma diffuser that provides different fragrances to a fresh air system. Background Technology

[0002] Shopping malls, hotels, office buildings, and other similar venues often use air conditioning and ventilation systems to emit scented air. The core principle behind this is that aroma diffusers atomize essential oils and integrate them into the air conditioning / ventilation system, allowing them to diffuse throughout the space. Aroma diffusers utilize physical atomization technology to transform liquid essential oils into micron- or nano-sized particles, enabling them to diffuse evenly with the airflow. Two main technologies are employed: firstly, two-fluid cold atomization technology, which uses compressed air to generate a high-speed airflow that impacts the surface of the essential oil liquid, tearing it into tiny particles; and secondly, ultrasonic oscillation technology, where a high-frequency oscillator breaks down a mixture of water and essential oils into microparticles. While ultrasonic oscillation technology produces water mist, affecting air humidity, two-fluid cold atomization technology requires no water, preserving the active ingredients of the essential oils and allowing them to remain suspended in the air for an extended period. Therefore, aroma diffusers combining air conditioning and ventilation systems with two-fluid cold atomization technology are the preferred choice. Existing aromatherapy diffusers used in air conditioning systems typically offer only one fragrance. Changing the scent requires replacing the essential oil bottle. Some machines have non-removable bottles, requiring users to wait for the stored oil to run out before refilling, which can lead to scent mixing. For machines with removable bottles, different bottles are used to change the fragrance. However, overall, changing scents is still inconvenient. Research and development are needed to address these technical issues and enable diffusers to switch scents in real-time to meet diverse consumer needs. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: The aroma diffuser designed with this technical solution mainly consists of at least two sets of essential oil atomizing units. Each essential oil atomizing unit includes an atomizing chamber body, an essential oil bottle, and an air pump. It utilizes a two-fluid structure working principle to atomize and output the essential oil in the essential oil bottle. The essential oil bottle contains essential oils of different scents. By controlling and selecting the corresponding air pump, the essential oil in the corresponding scented bottle is atomized. The atomized aroma is then delivered to the fresh air system through a fragrance delivery pipe. Therefore, this solution allows for the selection of atomizing different scented essential oils, providing different fragrance outputs to the fresh air system. Multiple essential oil atomizing units can operate simultaneously, delivering aroma to multiple different fresh air systems simultaneously through the pipes, or switching between different aroma inputs when supplying the same fresh air system. This solves the problem of existing fresh air systems not being convenient or quick enough for switching between different fragrance outputs. Attached Figure Description
