This utility model adopts following technical scheme:
Be applied to an anti-electric-shocking circuit for radio-frequency cosmetic instrument, comprise:
Controlled switch; Comprise controlled portion and switch portion; Wherein, switch portion comprises the first switch terminals for being connected with zero line and the second switch end for conducting;
Output port adapter; Output port adapter is provided with 4 output ports, is respectively: RF exports high voltage negative port, grounding ports, triggering controlled switch port and RF and exports high-voltage positive electrode port; Trigger controlled switch port to be connected with controlled portion signal;
Second switch end and the RF of described switch portion export high voltage negative port and are connected;
When radio-frequency cosmetic instrument uses, trigger controlled switch port and send signal to controlled portion, gauge tap portion of controlled portion disconnects; When radio-frequency cosmetic instrument suspends use, switch portion closes, the first switch terminals and the conducting of second switch end, and the electric charge that RF exports high voltage negative port is externally exported by switch portion.
Further, described controlled switch is normally opened relay.

The beneficial effect that this utility model obtains is: this utility model is easy to use, the electrode charge accumulation acting on human body can be avoided too much, cause electric shock, use safety.
Accompanying drawing explanation
Fig. 1 is a kind of circuit diagram of the present utility model.
In accompanying drawing, K represents controlled switch, and N represents zero line; J3 represents output port adapter, and wherein, port one is that RF exports high voltage negative port, and port 4 is RF output high-voltage positive electrode port, and port 3 is for triggering controlled switch port.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, book is described further to this utility model.
Embodiment: see Fig. 1.
Be applied to an anti-electric-shocking circuit for radio-frequency cosmetic instrument, comprise:
Controlled switch; Comprise controlled portion and switch portion; Wherein, switch portion comprises the first switch terminals for being connected with zero line and the second switch end for conducting;
Output port adapter; Output port adapter is provided with 4 output ports, is respectively: RF exports high voltage negative port, grounding ports, triggering controlled switch port and RF and exports high-voltage positive electrode port; Trigger controlled switch port to be connected with controlled portion signal;
Second switch end and the RF of described switch portion export high voltage negative port and are connected;
When radio-frequency cosmetic instrument uses, trigger controlled switch and send signal to controlled portion, gauge tap portion of controlled portion disconnects; When radio-frequency cosmetic instrument suspends use, switch portion closes, the first switch terminals and the conducting of second switch end, and the electric charge that RF exports high voltage negative port is externally exported by switch portion.Here time-out uses and refers to: radio-frequency cosmetic instrument is in "on" position, but does not act on human skin; Namely the gap stage is in.The input of output port adapter can be connected with the control chip of radio-frequency cosmetic instrument or control circuit.
This circuit in use, as shown in the figure, first switch terminals of switch portion is connected with zero line, the RF of output port adapter is exported high-voltage positive electrode port and is connected with the massage head of radio-frequency cosmetic instrument by wire, RF is exported high voltage negative port and is connected with the importing level of radio-frequency cosmetic instrument by wire, import level and directly act on human body, massage head is high insulation-grade; During use, massage head and importing level one react on human body; When changing use position, radio-frequency cosmetic instrument suspends use, now triggering controlled switch port sends signal to the controlled portion of controlled switch, switch portion closes, RF is exported high voltage negative and is connected with zero line by switch portion, the electric charge that RF exports in high voltage negative turns back to electrical network, thus reaches and lay down unnecessary electric charge object.Accumulation is avoided to form high electric current, electric shock user.In order to better respond to using state, can arrange induction apparatus in massage head or importing level, induction apparatus is connected with triggering controlled switch port; By massage head or import level and human contact, induction apparatus sends signal to triggering controlled switch port.
Further, described controlled switch is normally opened relay.
As shown in the figure, adopt normally opened relay structure simple, cost is low.Audion, metal-oxide-semiconductor etc. can certainly be adopted, as controlled switch.
Certainly, controlled switch can be also other form switches, as the switch by chip controls.
Further, described second switch end and RF export between high voltage negative port and are provided with capacitance module.
Arrange capacitance module, avoid heavy current impact, the electric charge of the high voltage negative of RF output simultaneously port can also store.
Further, described electric capacity module comprises the electric capacity C1 and electric capacity C2 that are connected in series; Wherein, electric capacity C2 is parallel with resistance R1.
Further, described controlled portion is parallel with one for preventing the diode D1 of reverse power connection.
The current direction of diode is contrary with the current direction in controlled portion; When reverse power connection, electric current directly flows through from diode, and controlled portion is shorted.
Below be only the preferred embodiment of the application, equivalent technical solutions on this basis still falls into application protection domain.
