moreover, through an EMS pulse circuit, the electronic pulse current can be generated and directly acts on muscle nerves of a muscle layer under the skin, and the electronic pulse current can directly reach the fat body in a deep layer, so that the local fat layer is fully exercised, and the basic metabolism of the human body is improved;

in addition, the first ultrasonic drive circuit and the high-voltage plasma generator module are integrated on the first printed circuit board, so that the space is effectively utilized, the assembly is convenient, and particularly, the stability and the reliability of the connection between the first ultrasonic drive circuit, the high-voltage plasma generator module and the ultrasonic energy conversion sheet are ensured;

and the whole structure design is ingenious and reasonable, the structure is compact, the volume is small, and the carrying, storage and management are convenient.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
