[0024] Please refer to Fig. 3As shown, in order to realize the technical effect that the control module 20 can make the first chip contact 101 and the second chip contact 102 be connected with the signal spring of the printing device at will, i.e. the first chip contact 101 and the second chip contact 102 can be installed in any installation direction without distinguishing the installation direction when installing the consumable chip, and the printing device can be normally used, an implementation manner of the control module 20 is provided.
[0025] Specifically, the first chip contact 101 (i.e. the chip contact 1 in the embodiment) is connected with the positive electrode end of the diode D1, the negative electrode end of the diode D1 is connected with the signal input end (i.e. the VDD end in the embodiment) of the master control unit 21, the second chip contact 102 (i.e. the chip contact 2 in the embodiment) is connected with the positive electrode end of the diode D3, the negative electrode end of the diode D3 is connected with the signal input end of the master control unit 21, the signal input end of the master control unit 21 is connected with the signal output end (i.e. the VSS end in the embodiment) of the master control unit 21 through the capacitor C1, the signal output end of the master control unit 21 is connected with the positive electrode end of the diode D2, the negative electrode end of the diode D2 is connected with the second chip contact 102, the signal output end of the master control unit 21 is connected with the positive electrode end of the diode D4, the negative electrode end of the diode D4 is connected with the first chip contact 101, the first data communication end (i.e. the data pin 1 in the embodiment) of the master control unit 21 is in communication connection with the first chip contact 101, and the second data communication end (i.e. the data pin 2 in the embodiment) of the master control unit 21 is in communication connection with the second chip contact 102.
[0026] Before the implementation principle of the control module 20 is described, it needs to be explained that the position where the printing device installs the consumable chip is provided with a single bus signal spring and a signal ground spring, the single bus signal spring has the functions of data transmission and power supply, and the signal ground spring is used for grounding connection between the printing device and the consumable chip. The specific working principle thereof is described below:
[0027] If the first chip contact 101 is connected with the single bus signal spring of the printing device, and the second chip contact 102 is connected with the signal ground spring of the printing device, when the printing device starts to work, the single bus signal spring outputs high level, so that the diode D1 is turned on, and the diode D3 and the diode D4 are turned off. Due to the charge and discharge characteristics of the capacitor C1, the capacitor C1 converts the high level signal transmitted after the diode D1 is turned on into a stable direct current signal, so that the main control unit 21 starts to work. At the same time, by using the one-way conduction characteristics of the diode, when the high level voltage output by the single bus signal spring is sufficient to turn on the diode D1 and the diode D2, and is sufficient to supply power to the main control unit 21, the signal output end of the main control unit 21 outputs a conduction voltage, so that the diode D2 is turned on, so that the first chip contact 101 and the second chip contact 102 form a power supply loop with the printing device. In addition, since the first data communication end of the main control unit 21 is connected with the first chip contact 101, when the single bus signal spring of the printing device outputs high level, the main control unit 21 will also trigger the data communication with the consumable chip, that is, the consumable chip will receive the command signal sent by the printing device through the first data communication end of the main control unit 21, and after the consumable chip processes the command signal, the command signal will be transmitted to the printing device through the first data communication end of the main control unit 21, so that the printing device executes the corresponding operation. In the whole process, the second data communication end of the main control unit 21 connected with the second chip contact 102 is always low level and is not triggered.
[0028] If the second chip contact 102 is connected to the single bus signal spring of the printing device and the first chip contact 101 is connected to the signal ground spring of the printing device when the printing device starts to work, the single bus signal spring outputs high level, so that the diode D3 is turned on and the diode D1 and the diode D2 are turned off. Due to the charge and discharge characteristics of the capacitor C1, the capacitor C1 converts the high level signal transmitted after the diode D3 is turned on into a stable direct current signal, so that the main control unit 21 starts to work. At the same time, when the high level voltage output by the single bus signal spring is sufficient to turn on the diode D3 and the diode D4 and to supply power to the main control unit 21, the signal output end of the main control unit 21 outputs a turn-on voltage, so that the diode D4 is turned on, thereby forming a power supply loop between the first chip contact 101 and the second chip contact 102 and the printing device. In addition, when the single bus signal spring of the printing device outputs high level, the main control unit 21 is triggered to communicate data with the consumable chip, that is, the consumable chip receives the command signal transmitted by the printing device through the second data communication end of the main control unit 21, and after the consumable chip processes the command signal, the command signal is transmitted to the printing device through the second data communication end of the main control unit 21, so that the printing device performs corresponding operation. In the whole process, the first data communication end of the main control unit 21 connected with the first chip contact 101 is always at low level and is not triggered.
[0029] In the embodiment, no matter how the first chip contact 101 and the second chip contact 102 are connected to the single bus signal spring and the signal ground spring of the printing device, an effective power supply loop can be formed, so that the consumable chip can obtain stable power supply in any installation direction.
[0030] In addition, the main control unit 21 is connected with the first chip contact 101 and the second chip contact 102 through two independent data communication ends (data pin 1 and data pin 2), so that no matter which contact is used as single bus signal input, the command signal can be effectively received and transmitted, thereby ensuring stable and reliable data exchange. In the data communication process, the data communication end which is not triggered remains at low level, unnecessary signal interference is avoided, and the accuracy and stability of data transmission are ensured.
[0031] Further, as a preferred embodiment of the scheme, the first chip contact 101 and the second chip contact 102 are arranged separately, and the first chip contact 101 and the second chip contact 102 both have the functions of power supply and data transmission.
[0032] In the embodiment, the first chip contact and the second chip contact are arranged apart from each other, avoiding malfunction caused by accidental contact between the chip contacts, and avoiding electrical interference between the chip contacts, improving the reliability and service life of the consumable chip; in addition, since each chip contact can perform power supply and data communication, when the chip is installed, no matter which direction the contact is installed in, the consumable chip and the printing device can work normally, further improving the flexibility of the consumable chip installation.
[0033] Further, as a preferred embodiment of the present scheme but not limited, the master control unit 21 can include but is not limited to a single-chip microcomputer, a microcontroller, an FPGA, etc. for data communication and data storage between the consumable chip and the printing device, in the embodiment, the master control unit 21 is selected as a microcontroller.
[0034] Further, as a preferred embodiment of the present scheme but not limited, the substrate 11 can include but is not limited to a flexible circuit board, a printed circuit board (PCB), a ceramic substrate, in the embodiment, the substrate 11 is selected as a flexible circuit board.
