The direction of the air flow generated by rotation of the first rotor of the fan and the direction of the air flow generated by rotation of the second rotor of the fan are different, and selection can be made according to needs; and the fan has the generality.
Description
Technical field
The present invention relates to a kind of fan.
Background technique
Existing fan generally can only provide unidirectional distinguished and admirable, when needs use different wind direction, needs to use different fans, does not have versatility.
Summary of the invention
In view of more than, be necessary to provide a kind of fan that different wind direction is provided.
A kind of fan, comprise a body, one first stator, one second stator, a first rotor and one second rotor, this body is provided with the through hole that runs through relative first side of body and the second side, contiguous first side of this first stator is installed in through hole, the first rotor rotates and is installed in the first stator, contiguous second side of second stator is installed in through hole, and this second rotor turns installs the second stator, and this first rotor is contrary with the wind direction that the second rotor produces.
Compare prior art, it is different that the first rotor and second rotor of this fan rotate the wind direction produced, and can select according to demand, have versatility.
Accompanying drawing explanation
Fig. 1 is the three-dimensional exploded view of the better embodiment of fan of the present invention.
Fig. 2 is the decomposed figure of Fig. 1.
Fig. 3 is the better embodiment of fan of the present invention and the constitutional diagram of a mainboard.
Fig. 4 is the control circuit figure of fan of the present invention.
Primary component symbol description
Following embodiment will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Embodiment
Please refer to Fig. 1 to Fig. 3, fan 10 of the present invention comprise a body 12, be installed in mutually deviate from body 12 the first stator 14, second stator 14a, rotate the first rotor 16 and the second rotor 18 and the control circuit that are installed in this first stator 14, second stator 14a respectively.
This body 12 comprises the through hole 126 that body 12 is run through in second side 124 and relative with the first side 122, one first side 122, this the first rotor 16 is installed in the side of contiguous first side 122 in through hole 126, and this second rotor 18 is installed in the side of contiguous second side 124 in through hole 126.The wind direction that this first rotor 16 and the second rotor 18 produce is contrary.
Please refer to Fig. 4, this control circuit, comprise a connector 30 being connected to fan 10 and selection module 40 and the fan governor 50 be located on fan 10.This connector 30 is connected to the integrated baseboard management controller (IBMC) 101 on mainboard 100.
This connector 30 comprises selects signal end Select; Pulse-width control signal end PWMA; Pulse-width control signal end PWMB; Power end+12V, connects power supply VCC; Grounding end GND, ground connection.
This selection module 40 comprises not gate U1, U2 and transmission gate TG1, TG2, the input end of not gate U1 is connected with the first pin of connector 30, the input end of the output terminal AND NOT gate U2 of not gate U1 is connected, the output terminal of the low level control end AND NOT gate U1 of transmission gate TG1 is connected, the output terminal of the high level control end AND NOT gate U1 of transmission gate TG2 is connected, the low level control end of transmission gate TG2 is connected with the high level control end of transmission gate TG1, and the high level control end of output terminal transmission gate TG1 and the low level control end of transmission gate TG2 of not gate U2 are connected.The input end of transmission gate TG1 is connected with the pulse-width control signal end PWMA of connector 30, the input end of transmission gate TG2 is connected with the pulse-width control signal end PWMB of connector 30, and the output terminal of transmission gate TG1 and the output terminal of transmission gate TG2 are connected with fan governor 50 respectively.
Be described to the working principle of said fans control circuit below:
When the wind direction needed is when blowing to the second side 124 from the first side 122, the selection signal end Select of integrated baseboard management controller 101 control connector 30 exports high level, not gate U1 input end is high level, output terminal is low level, not gate U2 input end is low level, and output terminal is high level.Now, transmission gate TG1 high level control end is high level, and low level control end is low level, transmission gate TG1 conducting; Transmission gate TG2 high level control end is low level, and low level control end is high level, and transmission gate TG2 ends.The pulse-width control signal end PWMA of connector 30 exports one first pulse width signal to the first rotor 16 by fan governor 50 makes the first rotor 16 rotate.
When the wind direction needed is when blowing to the first side 122 from the second side 124, integrated baseboard management controller 101 controls to select signal end Select output low level, and not gate U1 input end is low level, and output terminal is high level, not gate U2 input end is high level, and output terminal is low level.Now, transmission gate TG2 high level control end is high level, and low level control end is low level, transmission gate TG2 conducting; Transmission gate T1 high level control end is low level, and low level control end is high level, and transmission gate TG1 ends.The pulse-width control signal end PWMB of connector 30 exports one second pulse width signal to the second rotor 18 by fan governor 50, and the second rotor 18 is rotated.
In other embodiments, the first rotor 16 can be contrary with the second rotor 18 flabellum direction, and the distinguished and admirable of the first rotor 16 generation blows to outside the first side 122, distinguished and admirable the blowing to outside the second side 124 of the second rotor 18 generation.
Thus, fan 10 of the present invention can control the wind direction of fan 10 by fan control circuitry, simple and convenient.
