     Please refer to  FIG. 1  to  FIG. 7  for an exemplary description of an aroma diffuser provided in the present application. The aroma diffuser includes a body  10  and a touch screen  20 . 
     The body  10  has an atomization component inside, and the atomization component is configured to atomize essential oil and discharge it through an atomization port  101  located on an upper surface. It can be understood that if the essential oil is replaced with ordinary liquid water, the aroma diffuser in this embodiment becomes a humidifier, and the atomization component is configured to atomize the liquid water and discharge it through the atomizing port  101  located on the upper surface to achieve an effect of increasing the air humidity. 
     The touch screen  20  is provided on the upper surface of the body  10  and configured to control an operation of the body  10 . 
     The touch screen  20  integrates control buttons for an operation of the atomization component, including atomization switch, atomization mode selection, atomization time selection, etc. Each control button may be a touch key, which can beautify the appearance and avoid misoperation caused by mechanical touch compared to mechanical buttons. 
     In the structure shown in  FIG. 3 , the touch keys include an atomization mode selection key (i.e., mist mode) and an atomization time selection key (i.e., mist time). A user may select an atomization mode by touching the atomization mode selection key with a finger to adjust an atomization speed. Three mode display signal lamps are provided next to the atomization mode selection key to visually display the atomization mode selected by the user. The user may select an atomization time by touching the atomization time selection key with a finger. In this embodiment, three atomization time options may be set in the aroma diffuser, i.e., 4 hours, 8 hours and 12 hours for atomization.

     The touch keys are distributed on the touch screen  20  and arranged along the circumference of the touch screen  20 . In combination with use environment of the aroma diffuser, the touch keys are arranged on the upper surface of the body  10 , which may not be easily blocked by the body  10  itself and are more intuitive to be seen, compared to be arranged on the side surface of the body  10 , thus facilitating the convenience of operation. 
     The touch operation surface  201  is inclined toward the atomization port  101 , or recessed downward, so that the touch keys are lower than the level of the upper surface of the aroma diffuser. In other words, the touch keys do not protrude from the upper surface of the aroma diffuser, thereby reducing a risk of accidentally touching the touch keys by human hands during transportation or other situations. On the other hand, the downwardly recessed or downwardly inclined arrangement conforms to the contour of a human finger, and improves an overall aesthetic effect without affecting the convenience of use. 
     In view of the above, the aroma diffuser provided by the present application adopts the touch screen  20  to operate and control the body  10 , which can avoid the misoperation of mechanical touch. The touch screen  20  is arranged on the upper surface of the body  10  which facilitates operation. The touch operation surface  201  has a ring shaped, and its cross-section is inclined or recessed downwardly towards the atomization port  101 , which improves the aesthetics and reduces the risk of accidentally touching the touch keys by human hands during transportation or other situations. 
     In another embodiment of the present application, the touch screen  20  has a light transmissive structure at the position of each touch key. The touch keys are provided with a luminous body, and the luminous body emits light to make each touch key brightly displayed when any touch key is triggered. 
     In this embodiment, the touch screen  20  is configured to enable all the touch keys being displayed brightly when any touch key is touched by a human hand and to turned off the bright display after a specific time. The touch screen  20  may not be easy to find the accurate position of each touch key in a dark environment such as night, thus the touch screen  20  is configured to make all touch keys brightly displayed when it is touched by a human hand for the first time, thereby facilitating the user to check the position of each touch key for subsequent control operations. It should be understood that the time for all the touch keys to light up can be 1 second, 2 seconds, 3 seconds, etc. After a preset time is reached, the bright display will be turned off automatically.
