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.Electrode slice is one of very important parts of electro-therapeutic apparatus of intermediate frequency.It directly contacts with human body, alternating current power supply is directly powered to electrode slice by power supply processing circuit, due to human body institute static electrification, its voltage may be up to several kilovolts of hundreds ofs, especially in dry environment, very easily by electrode slice, produce backflow, electrode slice controller or other electronic components are damaged.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of safe, single-minded kind of electro-therapeutic apparatus of intermediate frequency battery lead plate power supply circuits can avoiding static to disturb circuit.
The present invention addresses the above problem adopted technical scheme:
A kind of electro-therapeutic apparatus of intermediate frequency battery lead plate power supply circuits, comprise port a, described port a is connected on the input of bridge rectifier, the outfan of described bridge rectifier is connected on the negative pole of diode, the negative pole of described diode is connected with the first pin of three terminal regulator LM7815, the first pin of described three terminal regulator LM7815, on the 3rd pin, be connected with respectively the first decoupling circuit, the second decoupling circuit, on described port a, be connected with resettable fuse, the outfan of described bridge rectifier is connected on port b, the first described decoupling circuit, the second decoupling circuit includes the first electric capacity and the second electric capacity, the first described electric capacity and the second electric capacity are in parallel and a common end grounding, described diode is commutation diode.LM7815 is three terminal regulator, and its first pin, the second pin and the 3rd pin are respectively pin Input, pin GND and pin Ouput.In the present invention, port a is connected on power supply, be in alternating current power supply, after bridge rectifier rectification, send commutation diode to, commutation diode has unilateal conduction performance, it allows electric current to flow to three terminal regulator LM7815 end from bridge rectifier end, and the power voltage supply pole piece that three terminal regulator LM7815 exports 15V is used.Because rectification diode has one-way transmission, the electrostatic induced current that on its electrode slice, electrostatic potential produces can not reflux, and the static of human body can not damage circuit or electrode slice controller, and it is safe, uses reliable.Three terminal regulator LM7815 produces the voltage of 15V, and the controller of electrode slice needs voltage.Port b produces a pulsating volage, and the controller that directly offers electrode slice uses, and electrode slice is synchronizeed with the control signal of controller.Voltage input end at three terminal regulator LM7815 is connected respectively the first decoupling circuit and the second decoupling circuit with voltage output end, and decoupling circuit filtering high-frequency signal changes the transient response of circuit, the stability of intensifier circuit.Resettable fuse is protected whole circuit, and when short circuit or overload appear in circuit, resettable fuse automatically disconnects circuit is protected.
As preferably, described diode is IN4007.Commutation diode adopts IN4007, and it has stronger forward surge withstand resistance and low reverse current leakage, can improve the overall performance of circuit.
As preferably, the first described electric capacity, the capacitance of the second electric capacity are respectively 0.1 μ f, 10 μ f.。Adopt the electric capacity of 0.1 μ f, its capacitance is little, can effectively reduce the internal resistance of power supply high frequency.The first electric capacity and the second Capacitance parallel connection form decoupling circuit, its capacitance small one and large one, utilize large capacitance electric capacity little to low frequency signal capacitive reactance, the characteristic that low-capacitance electric capacity is little to high-frequency signal capacitive reactance, reduces the interference of power supply.
To sum up, the invention has the beneficial effects as follows:
1, the present invention utilizes bridge rectifier to carry out rectification to power supply; and after commutation diode is processed, export to three terminal regulator LM7815 and produce 15V Voltage-output; because commutation diode has signal one-way transmission; static electricity on human body can not refluxed; electrode slice controller or other electronic components are protected, avoided static to damage it.
2, the present invention can prevent that static from refluxing, and can avoid static to disturb circuit, safe.
3, circuit structure of the present invention is simple, cheap for manufacturing cost.
