Main element symbol description
Following specific embodiment will further illustrate the present invention with reference to above-mentioned accompanying drawing.
Specific embodiment
Fig. 1 to Fig. 3 is refer to, fan of the present invention 10 includes a body 12, is installed in first mutually deviated from body 12
Stator 14, the second stator 14a, rotate be installed in first stator 14, the first rotor 16 of the second stator 14a and second turn respectively
The control circuit of son 18 and.
The body 12 includes an a first side 122, second side 124 and relative with first side 122 through this
The through hole 126 of body 12, the first rotor 16 is installed in the side of neighbouring first side 122 in through hole 126, and second rotor 18 is filled
The side of neighbouring second side 124 in through hole 126.The wind direction phase that 16 and second rotor of the first rotor 18 is produced
Instead.
Fig. 4 is refer to, the control circuit, including a connector 30 and on fan 10 for being connected to fan 10
The fan governor 50 of selecting module 40 and.The connector 30 is connected to the integrated baseboard management controller on mainboard 100
（IBMC）101.
The connector 30 includes selection signal end Select；Pulse-width control signal end PWMA；Pulse-width control signal end PWMB；
Power end+12V, connection power supply VCC；Earth terminal GND, ground connection.
The selecting module 40 includes not gate U1, U2 and transmission gate TG1, TG2, input and the connector 30 of not gate U1
First pin is connected, and the input of the output end NAND gate U2 of not gate U1 is connected, the low level control end NAND gate of transmission gate TG1
The output end of U1 is connected, and the output end of the high level control end NAND gate U1 of transmission gate TG2 is connected, the low level of transmission gate TG2
Control end is connected with the high level control end of transmission gate TG1, the high level control end and biography of the output end transmission gate TG1 of not gate U2
The low level control end of defeated door TG2 is connected.The pulse-width control signal end PWMA phases of the input of transmission gate TG1 and connector 30
Even, the input of transmission gate TG2 is connected with the pulse-width control signal end PWMB of connector 30, the output end and biography of transmission gate TG1
The output end of defeated door TG2 is connected with fan governor 50 respectively.
The operation principle of said fans control circuit will be illustrated below：
When the wind direction for needing is integrated baseboard management controller when blowing to second side 124 from first side 122
The selection signal end Select output high level of 101 control connector 30, not gate U1 inputs are high level, and output end is low electricity
Flat, not gate U2 inputs are low level, and output end is high level.Now, transmission gate TG1 high level control end is high level, low
Automatic level control end is low level, transmission gate TG1 conductings；Transmission gate TG2 high level control end is low level, and low level control end is
High level, transmission gate TG2 cut-offs.The pulse-width control signal end PWMA of connector 30 exports one first arteries and veins by fan governor 50
Bandwidth signals to the first rotor 16 rotates the first rotor 16.
When the wind direction for needing is integrated baseboard management controller when blowing to first side 122 from second side 124
101 control selections signal end Select export low level, and not gate U1 inputs are low level, and output end is high level, not gate U2
Input is high level, and output end is low level.Now, transmission gate TG2 high level control end is high level, low level control end
It is low level, transmission gate TG2 conductings；Transmission gate T1 high level control end is low level, and low level control end is high level, transmission
