Ultrasonic fast dissolving cup capable of achieving wireless charging

The invention discloses an ultrasonic fast dissolving cup capable of achieving wireless charging. The ultrasonic fast dissolving cup comprises a cup body and a base. The cup body comprises an outer cup wall, an inner cup wall and a cup bottom. The cup bottom comprises a switch, a wireless receiving device and an ultrasonic oscillation device. The base comprises a power line, a power plug and a wireless transmission device. Energy is transmitted through near-field induction by means of the wireless receiving device and the wireless transmission device, the wireless charging function is achieved, and electric energy is supplied to an electricity utilization circuit. After the circuit is powered on, the ultrasonic oscillation device generates mechanical vibration, and therefore solute in water can be rapidly dissolved under the effect of ultrasonic waves, and the ultrasonic fast dissolving cup has the technical advantages of being safe to use and convenient to carry on the basis of rapid dissolving.
