[0048] A circuit device, which can be a printing device. The circuit device includes an electrical appliance 3 and a circuit device.

[0049] Reference Figure 4 、 Figure 5 The circuit device includes a main control circuit board 2 and at least one auxiliary circuit board 1.

[0050] The main control circuit board 2 is used to send signals to send corresponding control instructions to each electrical appliance 3. In this embodiment, the number of the main control circuit boards 2 is only one. The main control circuit board 2 is provided with a plurality of transmission ports 21, and the number of the transmission ports 21 is the same as and corresponds to the number of the auxiliary circuit boards 1 one by one. The main control circuit board 2 is provided with a first identifier 22 corresponding to each transmission port 21 around each transmission port 21, and the first identifier 22 is one of numbers, letters, symbols and colors.

[0051] Reference Figures 1-3, the auxiliary circuit board 1 is adapted to be connected to the main control circuit board 2 and at least two electrical appliances 3. The auxiliary circuit board 1 is a transfer station between the main control circuit board 2 and the electrical appliances 3, and it only conducts the transmission of signals, current, and voltage, without performing other processing tasks, such as signal processing, current and voltage variation, etc. Each auxiliary circuit board 1 is respectively provided with a second identifier 14 corresponding to the first identifier 22, or the circuit device is provided with a second identifier 14 corresponding to the first identifier 22 near each auxiliary circuit board 1. The second identifier 14 is one of numbers, letters, symbols, and colors. Preferably, the second identifier 14 represents the same information as the first identifier 22, so as to know the position of the transmission port 21 connected to this auxiliary circuit board 1, or to know the position of the auxiliary circuit board 1 connected to this transmission port 21. The first identifier 22 and the second identifier 14 can be manufactured at the time of factory, or can be added later by oneself.

[0052] To only achieve the function of signal, current, and voltage transmission. The electrical components on the auxiliary circuit board 1 only include the first connector 11 and the second connector 12, without any other electrical components, such as capacitors, resistors, CPUs, etc.

[0053] The first connector 11 is adapted to be connected to the transmission port 21 on the main control circuit board 2, and the connection between them is a wired connection. For example, it is a plug-and-play wired connection.

[0054] The number of the second connectors 12 is at least two, and each second connector 12 is respectively adapted to be connected to each electrical appliance 3. During use, when the number of the second connectors 12 is multiple, it is not required that each second connector 12 be used, which is mainly related to the number of electrical appliances 3 in the area where this auxiliary circuit board 1 is located. In this embodiment, the total number of the second connectors 12 on this auxiliary circuit board 1 is 10, but the number of the second connectors 12 used by each auxiliary circuit board 1 can be different.

[0055] The auxiliary circuit board 1 further includes an electrical circuit 13, and both ends of the electrical circuit 13 are respectively connected to the first connector 11 and the second connector 12.

[0056] Reference Figure 4 , Figure 5 , the connection between the electrical appliance 3 and the second connector 12 is a wired connection. For example, it is a plug-and-play wired connection. The electrical appliance 3 communicates with the main control circuit board 2 indirectly by connecting to the auxiliary circuit board 1. The electrical appliances 3 located on the same auxiliary circuit board 1 can be the same or different. The electrical appliance 3 can be a pressure sensor, a solenoid valve, a flow meter, etc.

[0057] In this embodiment, reference Figure 5, the main control circuit board 2 has four transmission ports 21, and the corresponding first identifiers 22 are A, B, C, and D respectively; the auxiliary circuit board 1 has four, and the corresponding second identifiers 14 are A, B, C, and D respectively, and are connected to the corresponding transmission ports 21. Each auxiliary board has four second connectors 12. For the auxiliary circuit board 1 with the second identifier 14 being A, its four second connectors 12 are respectively connected to four electrical appliances 3. For the auxiliary circuit board 1 with the second identifier 14 being B, only three of its four second connectors 12 are used and are respectively connected to three electrical appliances 3. For the auxiliary circuit board 1 with the second identifier 14 being C, only three of its four second connectors 12 are used and are respectively connected to three electrical appliances 3, and two of the electrical appliances 3 are the same as the two electrical appliances 3 connected to the auxiliary circuit board 1 with the second identifier 14 being A. For the auxiliary circuit board 1 with the second identifier 14 being D, only one of its four second connectors 12 is used and is connected to the corresponding electrical appliance 3.

[0058] In this embodiment, referring to Figures 6-9 , is the schematic diagram of the four transmission ports 21 of the main control circuit board 2. The electrical appliances 3 connected by each transmission port 21 through the auxiliary circuit board 1 are different. Therefore, the number of pins used in each transmission port 21 can be different, and the electricity and signals passing through can also be different.

[0059] It can be seen that through the function of the auxiliary circuit board 1, each auxiliary circuit board 1 is distributed in each area to be connected to the electrical appliances 3 in the corresponding area, which can reduce the number of wiring, and the wiring is not messy, facilitating installation and disassembly and reducing costs.

[0063] By using the auxiliary circuit board 1 as a transfer station between the main control circuit board 2 and the electrical appliance 3, the transmission of signals, current, and voltage between the main control circuit board 2 and the electrical appliance 3 is realized to achieve control. Moreover, since the electrical components of the auxiliary circuit board 1 only include the first connector 11 and the second connector 12, which only perform the transmission of signals, current, and voltage, the cost is lower, the structure is simpler, the failure rate is lower, and the service life is longer. The number of the second connectors 12 is at least two, which can realize the connection of multiple electrical appliances 3, and the auxiliary circuit board 1 can be set closer to the corresponding electrical appliance 3, making the wiring shorter and easier to organize. Each electrical appliance 3 in the corresponding area is uniformly connected to the main control circuit board 2 through the first connector 11 without directly connecting to the main control circuit board 2, reducing the number of wirings and making the wirings not messy.

And when the main control circuit board 2 is connected to multiple auxiliary circuit boards 1, each auxiliary circuit board 1 can perform work area division for reasonable layout, making it easier to wire and the wirings not messy.

[0065] In an exemplary embodiment, the main control circuit board 2 is provided with a transmission port 21 connected to the first connector 11. The number of the transmission ports 21 is the same as and corresponds one by one to the number of the auxiliary circuit boards 1, so that the electrical appliances 3 connected to each auxiliary circuit board 1 can be controlled by one main control circuit board 2, reducing the cost and facilitating wiring at the same time.
