In addition, the capacitor C4 is electrically connected to the base B of the fifth switching element q5, and is electrically connected to the collector c of the sixth switching element. The operation principle of the #fan system 2 is as follows: First, when the sequence start group 23 receives the input voltage 91 at a first time, the start list 70 231 and the delay start unit 232 simultaneously receive the input voltage w as a work. Voltage. The diodes d6, 〇7 of the "starting unit 231" receive the input voltage 91, so that the switching element Qs is turned on, and the capacitor C3 starts charging until the voltage value of the capacitor A reaches the switching element Q7. When the voltage is started, the switching element Q7 is turned on, so that the first fan module 21 can be started. In this embodiment, by the charging circuit of the capacitor C3 and the resistor Rn, the current flowing through the first fan module 21 is increased at a relatively slow rate to achieve the soft start effect. 13 1280842 _ while delay circuit 234 receives the input voltage 91, the third switching element Q3 and the fourth switching element Q4 are turned on, and the capacitor Q starts charging to generate the control signal v! ' After the predetermined time, the The voltage value of the control money V1 is greater than the voltage value of the reference signal, and the output terminal __ outputs a positive voltage value to the δH gate of the second switching element Q2 to control the start of the start circuit 233. The second switch element Q2 is turned on. It should be noted that the predetermined time is determined according to the charging time of the capacitor Q and the resistor & the user can select different capacitor C2 and the resistor R6 ' to adjust according to the time to be delayed. The predetermined time, or when the resistor R6 is a variable resistor, adjusts the resistance of the resistor I to adjust the predetermined time. After the first switching element Q2 is turned on, the capacitor [I starts charging until the voltage of the capacitor C1 reaches the starting voltage of the first switching element Qi, and the first switching element Qi is turned on. The first fan module 22 is activated and the soft start effect is achieved. In addition, the fan system 2 of the embodiment further has the function of resetting, and the resetting method operates as follows: when the sequential starting module 23 receives the input voltage 91, the switching elements Q7, Qs are turned on, and by the The voltage division of the resistor Ri2 'R!3 causes the second switching element Q6 of the delay circuit 234 to be turned on, and the capacitor C:4 starts charging, at which time the base B potential of the fifth switching element Qs is about zero. Is not conductive. When the user pulls the fan system 2 out of the electronic system (the sound is 1280842 stops feeding the input voltage 91), the capacitor C4 starts to discharge, and the voltage drop is generated as a turn-on voltage at the resistor Ru. The fifth switching element Q5 is turned on. At this time, the capacitor c2 can form a discharge path through the fifth switch 7L to form a discharge path for releasing the stored charge of the capacitor c2, thereby achieving the effect of resetting, thereby preventing the next When the secondary user inserts the fan system 2 back into the electronic system, a malfunction occurs. Therefore, the fan system 2 of the embodiment activates the first fan module 21 and the second fan module 22 at different times by the sequence starting module 23 φ to achieve the function of sequential startup and has a weight In addition, although only two fan modules are shown in FIG. 4, it is not limited thereto, and a plurality of fan modules may be configured according to a user's needs. In summary, the fan system according to the present invention and the sequence starting module and the delay starting unit start a plurality of fan modules at different time points to achieve the function of sequential starting to prevent the starting of the fan modules. Produce a large starting current and surge current to cause malfunction, and start the fan module components to ensure that the fan system can operate normally, avoiding damage to the electronic system and fan system, and can replace the analog control chip to reduce Overall production costs. In addition, the present invention has the effect of resetting, and the electric charge remaining in the fan system can be discharged to avoid malfunction.
