The speed-regulating stirrer circuit structurally comprises a resistor R1, a grid electrode of an MOS tube Q2, a resistor R2, a chip NE555, a drain electrode of the MOS tube Q2, a power source VCC, a resistor R4, a resistor R5, a diode D1, a diode D2, a capacitor C1 and a capacitor C2. A motor composed of the speed-regulating stirrer circuit can automatically achieve rotation and non-rotation states, and the rotation speed of the motor is adjustable.
Description
Technical field
The present invention relates to a kind of adjustable speed electric stirring technology, according to pulse length modulation principle, adjust the rotating speed of mixer, reached widely applicable effect.
Background technology
The thing such as often can steep milk, coffee at home, beat eggs.But it is even not that we often can stir in the time stirring, or undue force, so not only time-consuming but also effort, adopted this mixer, not only can accomplish to save time but also can be laborsaving, and the good results are evident.
Summary of the invention
The object of the invention is to provide for the deficiencies in the prior art a kind of design of speed stirrer circuit.
In circuit of the present invention: R1 is 100K resistance, be connected together with metal-oxide-semiconductor Q2 grid and R2, resistance R 2 other ends of 4.7K connect 3 pin of chip NE555, motor one end ground connection, the drain electrode of another termination metal-oxide-semiconductor Q2.The source class of Q2 meets power supply VCC1, resistance R 4 one pin of 100 Ω meet VCC2, another pin connects the c pin of the adjustable resistance R5 of 10K, the b pin of R5 connects the negative electrode of diode D1 and 7 pin of chip NE555, the a pin of R5 connects the resistance R 3 of 100 Ω, another pin of R3 resistance connects D2 anode, diode D2 anode, the negative electrode of diode D1, and 2 pin of chip NE555 are received the capacitor C 1 of 100nf together with 6 pin, 4 pin and 8 pin of chip NE555 meet power supply VCC3, 1 pin connects power supply ground, 5 pin are by capacitor C 2 ground connection of 100nf, VCC1, VCC2 and VCC3 are direct current pressure side, can adopt the low-voltage of 3V or 5V.
While switching on power, NE555 starts working, and now 2 pin of NE555 and 6 pin voltages are less than 1/3rd VCC2,7 pin electric discharge cut-offs.Capacitor C 1 is by R4, R5 and D1 charging.The 3 pin output high level of NE555, metal-oxide-semiconductor Q2 conducting, motor M G1 starts working.
In the time that C1 capacitance voltage is charged to 2/3rds VCC2,7 pin start electric discharge.Capacitor C 1 is by R3, R5
Discharge by 7 pin of NE555 with D2, the now 3 pin output low levels of NE555, metal-oxide-semiconductor Q2 turn-offs, and motor M G1 quits work.
The 3 pin pulse duty factors that can reach change chip NE555 by regulating resistance R5 reach the rotating speed that regulates motor M G1.
The invention has the beneficial effects as follows: motor can automatically be realized and rotate and do not rotate two states, and the rotary speed of motor is adjustable simultaneously.
