referring to fig. 1 and 2, the present invention provides a fan 10 capable of serving as a relay node, and the fan 10 can be implemented alone or in combination with other fans 20 having the same structure to form a fan system 300, as shown in fig. 3. First, a basic architecture of the fan 10 is described, the fan 10 has a frame 11, a driving component 12 and a fan blade 13, wherein the frame 11 is provided for the driving component 12 to be mounted thereon, the driving component 12 includes a circuit board 121, a driving unit 122 and a motor 123, the driving unit 122 may be composed of a plurality of electronic components disposed on the circuit board 121, and the electronic components may be an integrated circuit, a capacitor, a resistor or an inductor, respectively. The motor 123 is connected to the driving unit 122 and is controlled by the driving unit 122 to rotate. Furthermore, the fan 13 is disposed corresponding to the frame 11 and connected to the motor 123, and rotates relative to the frame 11 when the motor 123 rotates, so as to generate an air flow.
In summary, the fan 10 of the present invention further includes a male port 14, a female port 15, a transmission line set 16, a power obtaining unit 17 and a signal processing unit 18. The male port 14 and the female port 15 are implemented with the same communication specification, and the male port 14 and the female port 15 are respectively connected to the transmission line set 16. Furthermore, the male port 14 of the present invention can be further connected to a control source 400 to obtain a control signal 401 and an operating power 402 required by the operation from the control source 400, and the control source 400 of the present invention can be a fan controller or a computer motherboard. The transmission line group 16 is disposed on the frame 11, and the transmission line group 16 is not connected to a component other than the structure to which the fan 10 belongs. Further, the transmission line set 16 of the present invention at least includes two power lines 161, 162 for transmitting the operating power 402 and a control line 163 for transmitting the control signal 401, wherein the power lines 161, 162 and the control line 163 are electrically connected to the male port 14 and the female port 15, respectively. One of the two power lines 161, 162 can be a live line (i.e., V +), the other can be a ground line (i.e., GND), and the control line 163 is used to transmit digital signals. Furthermore, the male port 14 of the present invention can be disposed on the frame 11, or extend to the outside of the frame 11 through a partial line segment of the transmission line set 16. On the other hand, the female port 15 of the present invention can be disposed on the frame 11 according to implementation requirements, when the female port 15 is disposed on the frame 11, the female port 15 and the male port 14 are respectively located at one of the four corners 111 of the frame 11, as shown in fig. 1, that is, the male port 14 and the female port 15 are respectively located at different corners 111.
Referring to fig. 1 and fig. 2, the power obtaining unit 17 of the present invention is connected to the two power lines 161 and 162 in parallel, that is, whether the power obtaining unit 17 is normal or not does not affect the two power lines 161 and 162. In one embodiment, the power obtaining unit 17 is composed of two power transmission lines 171 and 172, that is, the power obtaining unit 17 of the present invention does not necessarily have to have the functions of power conversion or power voltage stabilization. In addition, the power obtaining unit 17 is electrically connected to the driving unit 122 and the signal processing unit 18, so as to provide the operating power 402 to the driving unit 122 and the signal processing unit 18. On the other hand, the signal processing unit 18 of the present invention is connected to the control line 163 to receive the control signal 401, and transmit the control signal 401 to the driving unit 122, so that the driving unit 122 controls the operation of the motor 123 based on the control signal 401, thereby adjusting the rotation speed of the fan blade 13. Furthermore, the signal processing unit 18 of the present invention further serves as a relay point to transmit the received control signal 401 to the female port 15 via the control line 163. More specifically, the control line 163 of the present invention includes a first control line segment 164 connecting the male port 14 and the signal processing unit 18, and a second control line segment 165 connecting the signal processing unit 18 and the female port 15.
Referring to fig. 3 to 5, it can be seen from the foregoing that the fan system 300 is formed by implementing the fan 10 of the present invention with another fan 20 having the same structure. In practice, the male port 14 of one of the fans 10 is connected to the control source 400, and the female port 15 of the same fan 10 is connected to the male port 24 of another fan 20. At this time, the two fans 10, 20 are linearly arranged, and the frames 11, 21 of the two fans 10, 20 are tightly connected, as shown in fig. 3 and 4. Accordingly, when the fan 10 connected to the control source 400 receives the operating power 402 and the control signal 401, the operating power 402 is input to the driving unit 122 and the signal processing unit 18 through the power obtaining unit 17, and is transmitted to another fan 20 through the two power lines 161 and 162, so that the other fan 20 can obtain the operating power 402 for operation. On the other hand, the control signal 401 is input to the signal processing unit 18 through the control line 163, and the signal processing unit 18 outputs the received control signal 401 to the female port 15 through the control line 163 in addition to inputting the control signal 401 to the driving unit 122, so that the other fan 20 can operate based on the control signal 401. As described above, the control signal 401 and the operating power 402 of the fan 20 are both obtained from the other fan 10 connected in the former relationship, and therefore, the other fan 20 connected in the latter relationship is regarded as a source of signal and power supply by the fan 10.
Referring to fig. 3 to fig. 5, in an embodiment, the control signal 401 further includes a rotational speed control command, and the driving unit 122 of each fan 10 of the present invention has a first mode receiving the control signal 401 and controlling the motor 123 to operate at a working rotational speed according to the rotational speed control command, and a second mode not receiving the control signal 401 and enabling the motor 123 to operate at a predetermined rotational speed. More specifically, when the fan 10 obtains the control signal 401 from the control source 400, the driving unit 122 enters the first mode and operates based on the rotational speed control command included in the control signal 401. On the contrary, when the fan 10 is started and the control signal 401 is not obtained from the control source 400, the driving unit 122 enters the second mode and operates at the predetermined rotation speed, which is referred to herein as the maximum rotation speed or the minimum rotation speed of the motor 123. Furthermore, when the fan 10 is implemented in multiple ways to form the fan system 300, once one of the fans 20 in the latter connection relation does not receive the control signal 401 transmitted by another fan 10, the driving unit 222 to which the fan 20 belongs enters the second mode, and the motor 223 to which the fan 20 belongs is made to operate at the preset rotation speed. Therefore, the invention solves the problem that each fan of the existing fan system cannot work once the master controller is abnormal.
Referring to fig. 7, in an embodiment, the driving assembly 12 further includes a sensing unit 124 disposed on the circuit board 121, and the sensing unit 124 is used for detecting a working state of the fan 10, where the working state may be a fan speed, a fan temperature, a fan noise, and the like. In this embodiment, the signal processing unit 18 can be used with the sensing unit 124 to perform rotation speed monitoring, temperature monitoring, noise monitoring, etc. on the fan 10. Specifically, the sensing unit 124 is used for sensing the rotation speed of the fan 10, and the signal processing unit 18 receives a current rotation speed signal from the sensing unit 124 and controls the motor 123 based on the finally set operation. Furthermore, when the sensing unit 124 is used for sensing the temperature of the fan 10, the signal processing unit 18 receives a fan temperature signal from the sensing unit 124 and controls whether the driving unit 122 changes the operating state to avoid the over-temperature of the fan 10 based on the set temperature condition. In addition, when the sensing unit 124 is used for sensing the working volume of the fan 10, the signal processing unit 18 can receive a fan volume signal from the sensing unit 124, and control the motor 123 based on a noise limitation condition set by the signal processing unit 18, so that the motor 123 is decelerated moderately, thereby preventing the working sound of the fan 10 from being too loud and being regarded as noise by a user. On the other hand, in this embodiment, the transmission line set 16 further includes a communication line 166 connecting the male port 14, the female port 15 and the signal processing unit 18, the sensing unit 124 is connected to the signal processing unit 18 and transmits a fan operating signal 403, and the signal processing unit 18 receives the fan operating signal 403 and then transmits the fan operating signal 403 to the control source 400 through the communication line 166, so that the control source 400 can obtain the state of the fan 10 by reading the fan operating signal 403. Further, the communication line 166 of the present invention includes a first communication line segment 167 connecting the male port 14 and the signal processing unit 18, and a second communication line segment 168 connecting the signal processing unit 18 and the female port 15.
Further, since the fan 10 of the present invention can be implemented in multiple numbers to form the fan system 300, in order to distinguish the fan operating signals 403 transmitted by each of the fans 10(20), in an embodiment, each of the fans 10(20) has a device identifier defined in the signal processing units 18(28), and each of the signal processing units 18(28) writes the device identifier of its own into the fan operating signals 403 when transmitting the fan operating signals 403 back to the control source 400, so that the control source 400 can distinguish the status of each of the fans 10(20) based on the device identifier included in each of the fan operating signals 403. Further, the control source 400 can also display each of the decoded fan operating signals 403 on a display for the user to observe.
Referring to fig. 6, in an embodiment, the female port 15 of the present invention can also be disposed on the circuit board 121 except for the foregoing embodiments, when the female port 15 is disposed on the circuit board 121, the frame 11 provides the circuit board 121 to be disposed on a supporting seat 112, and the supporting seat 112 is provided with a notch 113 so that the female port 15 is located in the notch 113 and faces one side of the supporting seat 112.
Referring to fig. 1 and 2, the frame 11 of the present invention is formed with a plurality of supporting ribs 114 connected to the socket 112. Further, the transmission line assembly 16 of the present invention is connected to the driving unit 122 disposed on the circuit board 121 via one of the supporting ribs 114.
