In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the following specific embodiments, taken in conjunction with the accompanying drawings, in which:
fig. 1 is a schematic diagram of the circuit structure of the present invention.
Detailed Description
(example 1)
Fig. 1 shows a specific embodiment of the present invention, wherein fig. 1 is a schematic circuit diagram of the present invention.
Referring to fig. 1, a zero power consumption ship type switch speed regulation control circuit includes a power input port 1, a motor 2 connected with the power input port, a control chip 3 and a ship type switch circuit 4, wherein the control chip 3 is connected with the motor 2 through a driving circuit 5, the ship type switch circuit 4 includes a ship type switch SW, a sixth resistor R6, a fourth resistor R4, a second capacitor C2, a seventh resistor R7, an eighth resistor R8, a tenth resistor R10, a first one-way diode D1 and a second one-way diode D2, one ends of the seventh resistor R7, the tenth resistor R10 and the sixth resistor R6 are all connected to a TRI pin and a THR pin of the control chip 3, two ends of a first switch of the ship type switch SW are respectively and movably connected with the other ends of the seventh resistor R7 and the tenth resistor R10, and a public end of the first switch is connected with a second one-way diode D2, The eighth resistor R8 and the first unidirectional diode D1 are connected in series and then connected with the other end of the sixth resistor R6, the anode of the second unidirectional diode D2 is connected with the open end of the first switch, two ends of the second switch of the ship-shaped switch SW are both connected with the RESET pin of the control chip 3, the open end of the second switch is connected with the power input port, the fourth resistor is connected in series between the RESET pin and the DISC pin of the control chip, the cathode of the second unidirectional diode D2 is connected with the DISC pin, and the second capacitor C2 is connected between the TRI pin and the ground wire of the control chip 3.
The drive circuit 5 comprises an MOS tube Q3, a ninth resistor R9, a second resistor R2 and a triode Q5, wherein the drain electrode of the MOS tube is connected with the negative electrode of the motor, the source electrode of the MOS tube is grounded, the grid electrode of the MOS tube is connected with the signal output pin of the control chip through the ninth resistor, the emitting electrode of the triode is connected to the grid electrode of the MOS tube, the collecting electrode of the triode is grounded, the base electrode of the triode is connected with the signal output pin of the control chip, and the second resistor is connected between the base electrode of the triode and the collecting electrode of the triode.
The model of the control chip is NE 555.
The MOS tube is an NMOS tube and the triode is a PNP type triode.
The input voltage of the power supply input port is 12V.
And a fuse is connected in series with the anode of the power input port.
In the figure, when the ship-shaped switch is in the middle OFF gear, the ship-shaped switch is in the OFF state, the power supply cannot be supplied to the NE555 control chip through the ship-shaped switch to work, so that the fan product has a zero-power-consumption standby state when being plugged in, and the gear is in the fan OFF state.
When the DC12V power supply is communicated with VIN, the other path of the power supply provides a high level for the 4 pin of the reset terminal, so that the potential of the 4 pin of the reset terminal is always greater than 0.4V, otherwise, the 3 pin output terminal can output a low level regardless of the 2 and 6 pin states. The power supply also supplies power to the pins 6 and 2 of the upper comparator and the lower comparator of the NE555 IC through the diodes D1/D2 and the resistors R6/R8, wherein the pins 2 and 6 are complementary, the pin 2 only acts on low level, the high level does not act on the pin, namely the voltage is less than 1VIN/3, and the pin 3 outputs high level. Pin 6 is the threshold terminal and only works for high level, low level does not work for it, i.e. the input voltage is larger than 2VIN/3, called high trigger terminal, 3 pin outputs low level, but there is a prerequisite that 2 pin potential must be larger than 1VIN/3 to be effective.
When the ship-shaped switch is in the first gear (on the left side of the switch), the 2 and 6-pin states of the NE555 are controlled by setting the resistance value of the resistor R7 to be connected in parallel with the resistors R6 and R8, at the moment, the 3 pin outputs a duty ratio to directly control the on-off of the N-MOS transistor Q3 to control the rotating speed of the fan, the larger the resistance value of the resistor R7 is, the smaller the duty ratio output by the 3 pin is, and the smaller the wind speed of the fan is, and the larger the wind speed of the fan is.
When the ship-shaped switch is in the second gear (on the right side of the switch), the 2 and 6-pin states of the NE555 are controlled by setting the resistance value of the resistor R10 to be connected in parallel with the resistors R6 and R8, at the moment, the 3 pin outputs a duty ratio to directly control the on-off of the N-MOS transistor Q3 to control the rotating speed of the fan, and as the resistor R10 takes the value of 0R, the 2-pin state is directly a high level, the duty ratio output by the 3 pin is 100% at the maximum, and the wind speed of the fan reaches the highest rotating speed state.
The utility model discloses a structure sets up rationally, and it is not influenced by electron original paper temperature when the deceleration control, is favorable to improving holistic stability in use and reliability, and the cost of manufacture of whole circuit is lower moreover, is favorable to reducing use cost, and the suitability is strong and the practicality is good.
