The present invention is generally related to negative ion generators, and more particular to a negative ion generator of improved structure.
Aromatherapy has been extensively covered in the media regarding its history and application development. While these reports remain somewhat reserved about whether aromatherapy can replace conventional medical treatments, they still provide many optimistic and positive assessments. Moreover, regardless of whether it can genuinely generate widespread therapeutic effects on the human body, as long as a pleasant indoor environment that can soothe the mind is established, people will alleviate discomfort and handle pressures more easily. This can enhance people's emotional management, leading to numerous benefits.
Traditionally, there are several methods for diffusing essential oils into the air, including the heating method (candle/incense warmer, electric diffuser), isopropanol diffusing method, and oxygen-containing diffusing method. However, these methods are generally not recommended by experts due to various factors such as the risk of overheating and combustion, the production of large aromatic molecules that don't disperse well, and the generation of ozone that is harmful to the environment.
Recently, a method that utilizes electrical power to generate high-frequency vibrations for rapidly oscillating and atomizing the mixture of essential oils and carrier liquids has been developed. This ultrasonic aromatherapy method creates a fine mist without the risks associated with heating. It's considered the most effective way to disperse essential oils by accelerating their breakdown into smaller particles. Especially noteworthy is the production of negative ions using ultrasonic aromatherapy, which has gained widespread acceptance for its beneficial effects. This method finds extensive application in households and public spaces.

The above-mentioned conventional negative ion generators have several drawbacks that could be improved, summarized as follows.
Conventional negative ion generators often utilize ceramic for their outer casings. While ceramic finishes do have their stylistic appeal, acquiring high-quality ceramic clay in recent years has become challenging. The production process for these ceramic casings also involves significant labor and time costs due to the difficulties in obtaining quality clay and the high rate of defects during the creation of raw ceramic forms. Additionally, the hand-painted glazing requires experienced artisans and is highly reliant on manual work. The final products are also vulnerable to damage during assembly, transportation, and use. The fragility of ceramic components leads to an elevated rate of returns for repairs and increased consumption of ceramic materials, resulting in substantial business expenses and human resource investment.
Furthermore, it is commonly observed that negative ion generators use cast iron for their base and stand. However, due to the gradual decline of the casting industry in recent years and the consequent increase in raw material costs, many factories have transitioned to precision machining and manufacturing. The shortage of factories and labor in the casting industry has also added pressure to the cost of casting products. Additionally, the transportation costs for the assembled products have been continuously rising, which becomes a significant obstacle to the promotion of the product.
Moreover, the commonly used nozzle design includes two types: direct spraying and oblique spraying. Users are required to frequently change nozzles according to their usage needs, and the nozzles are also prone to falling off due to accidental collisions. Apart from the high production costs, this design also results in extreme inconvenience during usage.
Therefore, a novel negative ion generator is provided herein. The negative ion generator includes an air spray unit, a water reservoir unit, an oscillation illumination assembly, an outer cylinder, and an air blower unit.
A major objective of the present invention is to use a highly durable material for the outer cylinder of the negative ion generator, allowing for customizable printing of distinct graphical patterns by transfer printing, painting, or laser engraving. This imparts a youthful and personalized appearance to the negative ion generator. Apart from enhancing the durability of the negative ion generator, this approach also reduces the substantial costs and human resources required for repairing or replacing ceramic casings due to damage. As a result, it achieves the dual purpose of improving quality and reducing expenses and wear.
Another objective of the present invention is that a dual-nozzle assembly on the air spray unit is designed with a rotary knob mechanism, providing both a vertical and an oblique channel. Through rotation, users can choose between a direct or oblique spray of the mist. This intricate design enhances user-friendliness, providing a more humane operation.
Yet another objective of the present invention is to incorporate a high-magnetic energy ring within the air spray unit that is made by a stamping process, rather than the conventional complex casting. This high-magnetic energy ring includes a high-magnetic energy rare earth ring, which can highly magnetize the passing water molecules and reorganize them to achieve an enhancement effect.
Furthermore, a soft water cup of the water reservoir unit employs a hook-on design, allowing users to easily replace the soft water cup and choose different essence flavors.
