Description

AROMA DIFFUSER

Technical Field

[0001] The utility model belongs to the field of humidifying atomizer apparatuses, and

in particular relates to an aroma diffuser.

Background Art

[0002] An ultrasonic atomizer surpasses a hearing range of people by means of

electronic high frequency oscillation with an oscillation frequency of 1.7MHz or

2.4MHz. The electronic oscillation is absolutely harmless to human body and animals.

By means of high frequency resonance of a ceramic atomizing sheet, a liquid state water

molecular structure is scattered to generate natural and elegant water mist without

heating or adding any chemical reagents. Compared with a heating and atomizing mode,

the energy source is saved by 90%. In addition, in the atomizing process, a lot of

negative ions will be released to be electrostatically reacted with smog, dust and the

like floating in air to precipitate, and meanwhile, harmful substances such as

formaldehyde, carbon monoxide and bacteria can be further removed effectively, such

that the air is purified, and occurrence of diseases is reduced. After essential oil is added,

the essential oil is atomized and decomposed by the aroma diffuser, such that negative

ions phytoncide in the essential oil drift away in the air and permeate into blood quickly

from a nasal cavity of a human body to promote blood circulation, accelerate

metabolism, adjust the physiological function, beautify the feature and protect the skin

and the sleep module can be only used for strong light and weak light modes. The period

is shortened as the brightness of the light is increased gradually. A sleep assistant mode

serves as a light timer, which is suitable for blacks out within 30 minutes. When being

activated, the button 11 of the aroma diffuser is pressed for two seconds to three seconds,

the timed indicator lamps 12 are turned on and turned off one by one. If the aroma

diffuser is to be activated, the switch 11 of the aroma diffuser is pressed momently again until the lamp is turned off directly. In default, when the 'timer' or 'automatic shutdown' function is activated, On-off of the lamp can be stilled set fully independent from the 'timer' and 'automatic shutdown' functions.

[0035] An independent light source mode: an independent light source is enabled or is

disabled. If the independent light source is enabled, the 'timed atomizing switch 10'

and the 'switch of the aroma diffuser 11' are clicked simultaneously until 'lH' and

'3H'indexes flicker alternately. When the independent night lamp is disabled, the

'timed atomizing switch 10' and the 'switch of the aroma diffuser 11' are reset. Same
