Atomization device, atomization device assembly, and control system of atomization device

An atomization device comprising:

• a main body that has a vibrating device and a cavity part and in which the vibrating device is disposed above the cavity part and includes a vibrating element;
• and
• a tank assembly that is detachably provided with respect to the main body and is accommodated in the cavity part in a coupled state of being attached to the main body,
• wherein the tank assembly comprises:
• a liquid supply tank that has a space to hold a liquid, and
• a liquid supply core that supplies the liquid in the liquid supply tank to one side of the vibrating device, and
• wherein the atomization device further comprises:
• a relay absorber disposed between the vibrating element and the liquid supply core,
• wherein the vibrating element comprises a mesh plate located in a central portion and a piezoelectric element located in a peripheral portion, the mesh plate has a dome part at a center of the vibrating element, and a part of the relay absorber is disposed in the dome part of the mesh plate,
• the relay absorber has a cut-out portion, and a part of the cut-out portion communicates with an inside of the dome part of the mesh plate,
• the relay absorber is deformable according to a shape of the dome part and substantially fills a gap between the vibrating element and the liquid supply core.
