Step S20, obtaining the movement speed of the hand-held part detected by the displacement detection module; generally, the displacement detection module includes a displacement sensor for detecting the movement speed of the hand-held part, and outputs the detected speed signal to the host;

Step S30 , determining the output power of the radio frequency power supply matched with the obtained movement speed of the hand-held part, and outputting the radio frequency energy corresponding to the power according to the matched output power of the radio frequency power supply.

In this solution, the treatment area is generally selected as a circular area or a sector area with a dot as the center of the circle, and the displacement sensor provided on the displacement detection module will obtain the movement speed of the hand-held part detected by the displacement detection module and feed it back to the host. , the host will determine the output power of the radio frequency power supply that matches the movement speed of the hand-held part, and output the radio-frequency power supply of the corresponding power according to the output power of the matching radio frequency power supply, so that the radio frequency treatment device can adjust the output according to the different movement speeds of the hand-held part.

In one embodiment, referring to FIG. 5 , the step of determining the output power of the radio frequency power supply matched by the movement speed of the obtained hand-held part, and outputting the radio frequency power supply of the corresponding power according to the matched output power of the radio frequency power supply includes:

Step S31, when the acquired motion speed of the hand-held part is greater than the first preset speed and less than or equal to the second preset speed, output the first power radio frequency energy; for example, when the motion speed of the hand-held part is V0, the first preset speed is Set the speed to 0 and the second preset speed to V1, then, when the host obtains the movement speed V0 of the hand-held part greater than the first preset speed and less than or equal to the second preset speed V1, then the output power of the radio frequency power supply is P1, It can be understood that the movement speed of the hand-held part is between the first preset speed and the second preset speed V1 for the first gear to output the first power radio frequency energy P1. Of course, the value of the first power radio frequency energy P1 can be determined according to the doctor. The clinical test or manufacturer-recommended settings are not limited here.

Step S32, when the obtained motion speed of the hand-held part is greater than the second preset speed and less than the third preset speed, output a second power radio frequency energy, and the second power changes correspondingly with the change of the motion speed of the hand-held part For example, when the second preset speed is V1 and the third preset speed is V2, when the obtained movement speed of the hand-held part is greater than the second preset speed V1 and less than the third preset speed V2, the second power is output The radio frequency energy P2, and the second power radio frequency energy may increase with the increase of the moving speed of the hand-held part. It can be understood that the movement speed of the hand-held part is between the second preset speed and the third preset speed. The second power level is used to output the second power radio frequency energy P2. In addition, the second power radio frequency energy and the moving speed of the hand-held part may also have a certain relationship, such as a linear relationship, a nonlinear relationship, or a functional relationship. The relationship is obtained by fitting after collecting sample data, so that the output radio frequency energy can meet the needs of different groups of people, so as to meet the needs of different groups of people and realize people's desire to reduce fat.
