If it isThe load weight ratio Z under two power values is not in the standard ratio interval, namely the operation condition of the simulated load under the two power values does not meet the preset condition, the controller considers that the radio frequency beauty instrument is unqualified and marks the power value of which the load weight ratio Z is not in 96-104% of the preset standard ratio interval, so that a tester can pertinently overhaul the radio frequency beauty instrument according to the marked power value. And after the radio frequency beauty instrument is repaired, the reliability test is carried out again, and the product is ready to leave the factory after the test is qualified.
The radio frequency beauty instrument is sold after being tested to be qualified, and the user can use the radio frequency beauty instrument to carry out beauty operation after purchasing the radio frequency beauty instrument from the factory. After the user starts the radio frequency beauty instrument, the controller outputs an IO control signal to the control terminal of the relay 2 through the IO control port PB15 at the bottom of fig. 2, so that the relay 2 is switched from the state shown in fig. 2 to communicate the rear port 5 and the rear port 4 thereof, that is, the rear end of the relay 2 communicates with the radio frequency massage head. The radio frequency beauty instrument of this embodiment is equipped with left and right two radio frequency massage heads, has connect relay 5 between relay 2 and these two radio frequency massage heads, and relay 2's back port 5 and port 4 connect relay 5's preceding port 3, and relay 5's back port 2 is connected to left radio frequency massage head negative pole through port 5 of connector 3, and relay 5's back port 4 is connected to right radio frequency massage head negative pole through port 4 of connector 3. In the state shown in fig. 2, the front port 3 of the relay 5 is communicated with the rear port 2 thereof so as to be communicated with the negative electrode of the left RF massage head through the port 5 of the connector 3, that is, the rear end of the relay 2 is communicated with the negative electrode of the left RF massage head, in this state, the positive electrode of the output end of the RF generator is connected with the RF-P port in fig. 2 so as to be connected to the port 1 of the connector 3 through the passage 6 so as to be communicated with the positive electrode of the left RF massage head, the negative electrode of the output end of the RF generator is connected with the RF-N port in the figure so as to be connected to the port 5 of the connector 3 through the rear ports 5 and 4 of the relay 2 and the rear port 2 of the relay 5 so as to be communicated with the negative electrode of the left RF massage head, so that a load circuit of the left RF massage head is formed, at this time, the detection ends of the current detection unit (i.e., the TC 11 port and the TC 12 port in fig. 2) are connected to the load circuit of the left RF massage head, and detecting the current of the load loop of the left radio frequency massage head. The user holds the left radio frequency massage head to stick to the skin part needing beauty treatment, then inputs the radio frequency output instruction, and the controller receives the instruction and then enables the radio frequency generator to output the corresponding power value, so that the left radio frequency massage head starts to work. The left radio frequency massage head is provided with a radio frequency indicator lamp for indicating the working state of the massage head, the anode of the radio frequency indicator lamp gets electricity from a load circuit on the left radio frequency massage head through a coupling circuit, the front port 6 of the relay 5 is communicated with the rear port 7 thereof in the state that the front port 3 of the relay 5 is communicated with the rear port 2 thereof, and the cathode of the radio frequency indicator lamp of the left radio frequency massage head is connected to the rear port 7 of the relay 5 through the port 2 of the connector 3, so that an indicator lamp loop is formed and the left radio frequency massage head is lighted when working.

the controller detects the load condition of the radio frequency massage head through a load detection module consisting of a current detection unit and a voltage detection unit, specifically, the current detection unit detects a current value I of the radio frequency massage head, the voltage detection unit detects a power supply voltage value of the radio frequency generator, the controller substitutes the detected power supply voltage value U and the detected current value I into a formula Z which is U/I to calculate a load weight ratio Z, and the load condition of the radio frequency massage head is judged by utilizing the load weight ratio Z. When the rf beauty instrument is working normally, the load weight ratio Z will be different due to some differences in parameters such as body type, skin humidity, and body conductivity of different users, but is usually higher than 6%, so the threshold value for determining whether the rf massage head is loaded or unloaded is set to 6% in this embodiment. The controller judges that the current load light-weight ratio Z is higher than 6 percent, and then the radio frequency massage head is considered to be in a loaded state. When the current skin part of the user is operated and the next skin part needs to be beautified, the user moves the radio frequency massage head away from the current skin part, because the radio frequency massage head leaves from the skin part and no load is consumed, the current value I in the load loop of the left radio frequency massage head is increased sharply, the current detection unit detects the current value of the load loop of the left radio frequency massage head, the voltage detection unit detects that the power supply voltage value U is unchanged, the current value signal and the voltage value signal at the moment form a no-load signal and are output to the controller together, the load weight ratio Z calculated by the controller according to the above is very small, the controller judges that the load weight ratio Z is less than 6 percent, the radio frequency massage head is considered to be not loaded, the power supply of the radio frequency generator is closed, and an IO control signal is output to the control end of the relay 2 through an IO control port PB15 in figure 2, thereby controlling the rear end of the relay 2 to be switched to be communicated with the analog load resistor 1. Therefore, the simulation load resistor 1 can consume the residual electric quantity in the radio frequency beauty instrument, effectively prevent the radio frequency massage head from accumulating electric charges and avoid the electric shock phenomenon. Because the rear end of the relay 2 is switched to be communicated with the simulation load resistor 1, the anode of the radio frequency indicator lamp can not be coupled and powered from the load loop of the left radio frequency massage head any more, and the radio frequency indicator lamp is turned off.
The controller of the above embodiment can execute the anti-electric shock automatic control process, but not preferably, other embodiments can take the fire-fighting electric shock automatic control process, and change the process into the process that a user manually turns off the power supply of the radio frequency beauty instrument and manually inputs an instruction to the controller to enable the rear end of the relay 2 to be switched to be communicated with the analog load resistor 1.

The user holds the right radio frequency massage head to stick to the skin part needing beauty treatment, then inputs the radio frequency output instruction, and the controller receives the instruction and then enables the radio frequency generator to output the corresponding power value, so that the right radio frequency massage head starts to work. The right radio frequency massage head is provided with a radio frequency indicator lamp used for indicating the working state of the massage head, the anode of the radio frequency indicator lamp gets electricity from a load circuit on the right radio frequency massage head through a coupling circuit, a front port 6 of a relay 5 is communicated with a rear port 5 thereof in the state that a front port 3 of the relay 5 is communicated with a rear port 4 thereof, and the cathode of the radio frequency indicator lamp of the right radio frequency massage head is connected to the rear port 5 of the relay 5 through a port 3 of a connector 3, so that an indicator lamp loop is formed and the right radio frequency massage head is lighted when working.
