Description
Technical field
This utility model relates to integrated circuit fields, particularly, relates to a kind of regulating circuit that is exclusively used in electro-therapeutic apparatus of intermediate frequency.
Background technology
Electro-therapeutic apparatus of intermediate frequency is the electric current of intermediate frequency by low frequency modulations.The feature that had so both retained low frequency electricity, has brought into play again the feature of medium frequency electric, and electrotherapy has analgesia, detumescence, antiinflammatory, desensitization, relieve muscle spasms, reinforcement tissue tension, promotes to recover the therapeutical effect such as normal nerve conduction and regulatory function.The electrode slice of electric therapeutic instrument directly contacts with people, and the safety of electrode slice is very important.Existing electrode slice is directly connected with control circuit, and in its circuit, easily produce and disturb, and two electrode slices contact formation loop with human body, human body institute static electrification, electrostatic potential is high, easily control circuit is damaged.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of regulating circuit that is exclusively used in electro-therapeutic apparatus of intermediate frequency, and it is connected between electrode slice and control circuit, the safety of intensifier electrode sheet, and static electricity on human body can not damaged control circuit.
The technical scheme in the invention for solving the above technical problem is:
Be exclusively used in the regulating circuit of electro-therapeutic apparatus of intermediate frequency, comprise chip MOC3020 and controllable silicon, the first pin of described chip MOC3020 is connected on power supply, the second pin of described chip MOC3020 is connected with port a by resistance R 1, the 4th pin of described chip MOC3020 is connected on the first anode of bidirectional triode thyristor by resistance R 2, the 6th pin of described chip MOC3020 is connected on the control end of bidirectional triode thyristor, and the first anode of described bidirectional triode thyristor and second plate are connected on joint b.Port a of the present utility model is connected on control circuit, and joint b is connected on electrode slice.Chip MOC3020 is optical coupling chip, and its first pin, the second pin, the 3rd pin, the 4th pin, the 5th pin and the 6th pin are respectively pin ANODE, pin CATHODE, pin NC, pin MAIN TERM, pin TRIAC SUB+ and pin MAIN TERM.Wherein the 3rd pin and the 5th pin respectively routinely connection be connected, meet chip MOC3020 service requirement.It is upper that control circuit is connected to port a, and the current signal of control circuit is through chip MOC3020, the conducting of optical coupling chip, and bidirectional triode thyristor also conducting in the conducting of optical coupling chip, controls electrode slice.Due to optical coupling chip, it has signal one-way transmission, be that input and output are isolated, the direction of transfer of the signal of telecommunication is restricted, can only be from control circuit end to electrode slice end, and static on the person can not be from electrode slice end to control circuit end, avoid the destruction of static to control circuit, the safety of intensifier electrode sheet.Adopt chip MOC3020, its input belongs to the low resistance element of current mode, adopts resistance R 2, and the electric current of its input is limited, and avoids large electric current to damage optical coupling chip, guarantees the reliability service of circuit, and it is the indispensable part of circuit.Resistance R 2 is connected between optical coupling chip and joint b, and electrode slice is protected, and avoids the destruction of large electric current to electrode slice, warrantor's safety.
As preferably, described bidirectional triode thyristor is BAT12.It has sensitive controlled stage trigger current BAT12, and on-state is forced down, and can guarantee effective conducting of circuit, guarantees the reliably working of electrode slice.
Further, described resistance R 2 and resistance R 1 are 150 ohm.
Further, described power supply is 5V.
To sum up, the beneficial effects of the utility model are:
1, circuit of the present utility model, the unidirectional general character that it utilizes optical coupling chip, makes the signal of telecommunication can only one-way transmission, has isolated the retroaction passage of static to control circuit, guarantees the reliability service of circuit, the security reliability of intensifier electrode sheet.
2, circuit structure of the present utility model is simple, practical.
