Atomization device

The invention provides an atomizing device capable of reducing residual liquid and stably spraying. The atomizing device comprises a body and a groove assembly. The body has a vibrator. The groove assembly is arranged to be capable of moving relative to the body, and the groove assembly is accommodated in the mold cavity in the combined state of the body and the groove assembly. The tank assembly comprises a liquid feeding tank, a supporting rod, a liquid core and an elastic component. The supporting rod is arranged in the liquid feeding groove, and in the combined state, the supporting rod is connected with the vibrator. The liquid core penetrates through the inner side of the supporting rod and is provided with a liquid absorbing end and an atomizing end. The elastic member is located on the bottom surface of the liquid supply tank and abuts against the liquid suction end to arrange the liquid core in the supporting rod at a preset interval, and the elastic member is composed of a fixed part and a movable p
