[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 , the present invention provides the following embodiments:

[0022] Embodiment 1:

[0023] A DC fan system of a plotter, comprising an electric signal acquisition module 1, an electric signal adjustment module 2, a fan wiring module 3 and a voltage adjustment module 4;

[0024] The electric signal acquisition module 1 is electrically connected to the electric signal adjustment module 2, and is used to collect the current signal of the working site where the DC fan is used, and convert the current signal into a first voltage signal or a second voltage signal;

[0025] One end of the fan wiring module 3 is electrically connected to the electric signal adjustment module 2, and the other end is electrically connected to the voltage adjustment module 4;

[0026] The voltage regulating module 4 is used to regulate the voltage to the rated working voltage of the DC fan according to the first voltage signal and the second voltage signal, so that the DC fan can operate normally under the working voltage of the work site.

[0027] When working, the fan is connected to the working power supply, and the current signal of the DC fan working site is collected through the electrical signal acquisition module 1, and the current signal is converted into a first voltage signal and a second voltage signal, and sent to the electrical signal adjustment module 2. The electrical signal adjustment module 2 determines whether the voltage regulation circuit needs to be switched according to the size of the collected voltage signal. When switching is required, the voltage adjustment module 2 adjusts it to the rated working voltage of 220V of the DC fan according to the collected first voltage signal and the second voltage signal, so that the DC fan can operate normally under the working voltage of the working site. When switching is not required, the DC fan directly operates normally.

[0028] The electrical signal acquisition module 1 includes a first voltage signal acquisition module 5 and a second voltage signal acquisition module 6 .

[0029] The voltage regulating module 4 includes a first voltage regulating circuit 7 , a second voltage regulating circuit 8 , a third voltage regulating circuit 9 and a fourth voltage regulating circuit 10 .

[0030] The first voltage regulating circuit 7 and the third voltage regulating circuit 9 are electrically connected to a first control switch 11 , and the second voltage regulating circuit 8 and the fourth voltage regulating circuit 10 are electrically connected to a second control switch 12 .

[0031] The first control switch 11 and the second control switch 12 are electrically connected to the electrical signal adjustment module 2 respectively.

[0032] The first voltage signal is greater than the second voltage signal.

[0033] The electrical signal regulating module 2 is an electromagnetic relay, which controls the first control switch 11 and the second control switch 12 to respectively turn on and off the first voltage regulating circuit 7, the second voltage regulating circuit 8, the third voltage regulating circuit 9 and the fourth voltage regulating circuit 10.

[0034] It should be noted that the first voltage signal is set to be greater than 220V, and the second voltage signal is set to be less than 220V. When the collected power supply voltage is greater than 220V, the electrical signal regulation module 2 controls the first control switch 11 to close and the second control switch 12 to open, so that the first voltage regulation circuit 7 and the third voltage regulation circuit 9 are in a fully conductive state, and the second voltage regulation circuit 8 and the fourth voltage regulation circuit 10 are in a fully disconnected state, thereby adjusting the circuit voltage to the adaptive voltage required by the fan. When the collected power supply voltage is less than 220V, the electrical signal regulation module 2 controls the first control switch 11 to open and the second control switch 12 to close, so that the first voltage regulation circuit 7 and the third voltage regulation circuit 9 are in a fully disconnected state, and the second voltage regulation circuit 8 and the fourth voltage regulation circuit 10 are in a fully conductive state, thereby adjusting the circuit voltage to the adaptive voltage required by the fan, thereby realizing automatic conversion of the power supply voltage, so that the power supply voltage of different work sites can be converted into the voltage required by the adaptive fan, thereby improving applicability.
