It should be understood that the specific embodiments described herein are merely configured to illustrate the invention and are not configured to limit the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by showing examples of the invention.
It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

The nozzles in the printer are typically connected independently of the other printing components in the printer by power lines to a nozzle receptacle. In the printing process of the printer, the other parts of the printer are electrified well, and printing failure caused by unsuccessful connection of the nozzle and the nozzle socket of the printer often occurs. When the spray head is not electrified normally, the spray head cannot be used normally, and ink cannot be discharged from the spray head in the printing process. When a user finds that the ink cannot be discharged from the spray head, after each part in the printer is checked one by one, the user can find that the spray head is not electrified so as to cause printing failure. In the prior art, a detection method for the un-electrified spray head is complex, and the detection process is time-consuming and labor-consuming.
The device, the method, the equipment and the medium for detecting the electrifying of the spray head control board can solve the technical problems of complicated and complex detecting process for detecting whether the spray head control board is electrified or not in the prior art to a certain extent.
An embodiment of the present invention provides a power-on detection device for a shower head control board, as shown in fig. 1, which includes a detection module 11, a shower head control board 12, a shower head power supply 13, and a shower head electronic component 120.
The head control board 12 is disposed inside the head and includes a PCB and various head electronic components 120 disposed on the PCB. Each head electronic component 120 is an electronic component. After the head control board 12 is normally powered on, each head electronics 120 will be able to function properly.
The detection module 11 is used for acquiring information from at least one nozzle electronic component 120 which is arranged on the nozzle control board 12 and is powered by the nozzle power supply 13 after the nozzle control board 12 is connected with the nozzle power supply 13, and judging whether the nozzle control board 12 is powered on according to the information acquisition result.
After the head control board 12 is connected to the head power supply 13, the head power supply 13 supplies power to each of the head electronic components 120 on the head control board 12 to activate each of the head electronic components 120.
After each head electronic component 120 is powered on, it can work normally and can interact with other head electronic components 120. The detection module 11 can determine whether the head control board 12 and the head power supply 13 are normally connected, and whether the head control board 12 is powered on and can be normally used by acquiring information from at least one head electronic component 120 and according to the information acquisition result for each head electronic component 120. If the electronic components 120 of the nozzles are powered on normally, the detection module 11 obtains the information of each electronic component 120 of the nozzles normally. If the electronic components 120 are not normally powered on, the information acquisition result of the detection module 11 for each electronic component 120 is abnormal. The information acquisition result includes whether the related information can be normally acquired from the head electronic part 120 or whether the information acquired from the head electronic part 120 is normal.
The head electronics 120 includes a head memory 121, a temperature sensor 122, and a driver chip 123.
Fig. 2 is an internal circuit diagram of the detection module 11, and two pins inside the first wire frame 200 are used to connect the head memory 121, and the detection module 11 reads data stored in the head memory 121 through the integrated circuit bus I2C bus protocol, thereby acquiring head internal information (head generation date, head reference voltage, etc. information). After the head control board 12 is powered up, N pieces of data are acquired from the head memory 121, and the first state is regarded as normal in software. If any one of the information acquisition signals sent from the detection module 11 to the head memory 121 is not acknowledged, the information acquisition result is considered to be failure.
Pins in the second wire frame 100 are used to connect to the temperature sensor 122. After the detection module 11 acquires the temperature signal from the temperature sensor 122, digital-to-analog conversion is performed on the acquired temperature signal, and finally the temperature signal is converted into a temperature value. If the temperature value obtained by conversion is greater than 0 and less than 60 degrees, the temperature information obtaining result is considered to be normal, otherwise, the temperature information obtaining result is judged to be abnormal, and the spray head control panel 12 is not electrified.
The pin in the third wire frame 300 is used to connect the driving chip 123, and outputs a high level by default, and when the head control board 12 is not connected to the head power supply, is not connected, or the head control board 12 is not powered on, the output level is low. Therefore, when the detection module 11 detects that the pin is at the high level, the third state is considered to be normal, whereas the third state is considered to be abnormal.
In one embodiment, FIG. 3 is a flow chart of an application for detecting whether the showerhead control plate 12 is powered up using the components of FIG. 2.
As shown in fig. 3, after the printer is powered on, the detection module 11 for detecting whether the head control board 12 is powered on acquires information of at least two head electronic components 120 provided on the head control board 12, and determines whether the head control board 12 is powered on according to the information acquisition result of each head electronic component 120. If the detection module determines that the head control board 12 is powered on, the printer is operated normally to perform a print job. If the detection module 11 determines that the head control board 12 is not powered on, a prompt message is generated. After the user sees the prompt, the printer will be turned off, and the cause of the head control board 12 not being powered on will be examined. And restarting the printer after the investigation is completed.
In one embodiment, as shown in FIG. 5, the showerhead electronics 120 includes a showerhead memory 121. The information acquisition result includes that the related information of the head can be normally acquired from the head memory 121, and that the related information of the head cannot be normally acquired from the head memory 121.
The head memory 121 is disposed inside the head, electrically connected to the head power supply, and used for storing information about the head.
In one or more embodiments provided herein, the head Memory 121 includes an EEPROM (Electrically erasable-Erasable Programmable Read-Only Memory). The EEPROM includes an EEPROM model M24C 32-D.
If the detection module 11 can normally acquire the related information of the nozzle from the nozzle memory 121, the nozzle memory 121 is powered on successfully.
The relevant information of the spray head comprises the production date of the spray head, the model of the spray head, printing information required by printing of the spray head, reference printing of the spray head and the like.
The detection module 11 is connected to the nozzle memory 121, and is configured to obtain information about the nozzle from the nozzle memory 121, and determine whether the nozzle control board 12 is powered on according to whether the information about the nozzle can be normally obtained from the nozzle memory 121.
The head memory 121 is provided on a circuit board inside the head. The circuit board inside the nozzle is used for installing each electronic component in the nozzle. When the head power supply 13 supplies power to the circuit board of the head, the circuit between the head memory 121 and the head power supply 13 is in a conductive state.
In one embodiment, after the head memory 121 is powered on, the detection module 11 sends a plurality of information acquisition signals to the head memory 121, and if the head memory 121 does not respond to any detection signal, the detection module 11 determines that the head control board 12 is not powered on.
Fig. 6 is a timing signal diagram of the pin connected to the head memory 121 in the detection module 11 shown in fig. 2, when the head memory 121 is detected. As shown in fig. 6, signals shown by the fourth wire frame 400, the fifth wire frame 500, the sixth wire frame 700, and the seventh wire frame 800 are response signals of the head memory 121. The signal in the eighth wire frame 600 indicates that the head memory 121 is not responding.
When the head memory 121 is normal, after the circuit between the head memory 121 and the head power supply 13 is in a conductive state, the head memory 121 can normally operate to provide print information required for printing to the head control board 12. During printing, the processor of the head control board 12 acquires print information from the head memory 121 and prints using the print information.
The detection module 11 can determine whether the head memory 121 can be used normally or not according to whether the head related information can be obtained normally from the head memory 121, and can determine whether the head control board 12 is powered on or not.
When the head control board 12 is powered on, the detection module 11 can normally acquire the relevant information of the head control board 12 from the head memory 121. When the head is not powered on, the detection module 11 cannot normally acquire the information about the head control board 12 from the head memory 121.
The detection module 11 can acquire the related information of the head control board 12 from the head memory 121, including the detection module 11 acquiring print information required for head printing from the head memory 121. In the printing process, the printer prints using the print information acquired from the head memory 121. After the head control board 12 is started, whether or not print information necessary for printing can be normally acquired from the head memory 121 can be judged as to whether or not the head memory 121 can be normally used, and whether or not the head control board 12 is powered on can be judged as to whether or not.
In one embodiment, as shown in FIG. 6, the showerhead electronics 120 includes a temperature sensor 122 and the information acquisition result includes whether the temperature signal acquired from the temperature sensor 122 is normal or not the temperature sensor 122 is electrically connected to the showerhead power supply 13. A temperature sensor 122 is installed inside the shower head to detect the temperature of the shower head control board 12 and generate a temperature signal according to the detection result.
In one embodiment, temperature sensor 122 comprises a thermistor. The resistance value of the thermistor changes with a change in temperature. After the head control board 12 is energized, heat is generated by energizing the electronic components in the head control board 12, and the temperature of the head control board 12 increases. When the temperature of the head control board 12 changes, the current value passing through the thermistor also changes, and this current value can be used as a temperature signal.
A temperature sensor 122 is provided on the head control board 12 for detecting the temperature of the head control board 12.
The detection module 11 is configured to determine whether the showerhead control plate 12 is powered on according to whether the temperature signal obtained from the temperature sensor 122 is normal.
When the showerhead control plate 12 is powered up, the temperature sensor 122 is also powered. The detection module 11 will acquire a temperature signal from the temperature sensor 122. The detection module 11 can convert the acquired temperature signal into a temperature value and then determine whether the head control board 12 has been energized by determining whether the temperature value is within a normal temperature range of the head control board 12. The normal temperature range of the spray head control board 12 is between 0-60 deg. when the spray head is in operation.
When the head control board 12 is powered on, each head electronic component 120 on the head control board 12 generates heat, and the temperature of the head control board 12 increases. The detection module 11 can determine that the head control board 12 is powered on when determining that the temperature of the head control board 12 is normal based on the temperature signal obtained by the temperature sensor 122.
In one embodiment, the temperature signal comprises an electrical signal within a set range of values. After the detection module 11 acquires the temperature signal, the temperature signal is used to calculate and acquire a temperature value. The value of the temperature signal is too high or too low, and the temperature value obtained by calculation is not in the normal temperature range. If the temperature value obtained by the calculation of the detection module 11 is not within the normal range, it may be determined that the temperature signal is not obtained by the detection module 11 normally, or it may be further determined that the temperature sensor 122 is not powered on normally. If the temperature sensor 122 is not powered up normally, the showerhead control plate 12 may not be powered up.
After the temperature sensor 122 is powered on, the detection module 11 can receive a temperature signal from the temperature sensor 122, and further obtain the temperature inside the shower head control board 12 according to the temperature signal. When the temperature sensor 122 is not powered on, the detection module 11 is unable to receive a temperature signal from the temperature sensor 122 or a normal temperature signal.
In one embodiment, as shown in FIG. 7, the electronic component 120 includes a driving chip 123, and the information acquisition result includes whether the electrical signal acquired from the driving chip 123 is normal.
The driving chip 123 is electrically connected to the head power supply 13, and is used for driving the electronic components on the head control board 12.
After the head is energized, the driver chip 123 will be in a conductive state with the head power supply 13. By detecting the driving chip 123, it can be determined whether the head control board 12 is powered on.
The driving chip 123 is electrically connected to the detection module 11 through pins. The driving chip 123 outputs a current or voltage to the detection module 11 after being energized. When the driving chip 123 is not energized, no current or no voltage is output to the detection module 11. The current or voltage output from the driving chip 123 to the detection module 11 is an electrical signal output from the driving chip 123 to the detection module 11.
And a detection module 11, configured to determine whether the head control board 12 is powered on according to whether the electrical signal acquired from the driving chip 123 is normal.
In one embodiment, the driver chip 123 sends a high level electrical signal to the detection module 11 when the connection between the head control board 12 and the head power supply 13 is successful. When the detection module 11 detects that the signal received from the driving chip 123 is a high level signal, the detection module 11 determines that the driving chip 123 is powered on successfully, otherwise, the detection module 11 determines that the driving chip 123 is powered on failed.
The electrical signal obtained from the driving chip 123 by the detection module 11 is a current signal higher than a first set value or a voltage signal higher than a second set value.
If the current value or the voltage value received by the detection module 11 is low, the current value or the voltage value received by the detection module 11 may be noise.
The detection module 11 can determine whether the driving chip 123 is energized or not based on whether the electric signal obtained from the driving chip 123 is normal or not, and can determine whether the head control board 12 is energized or not based on whether the driving chip 123 is energized or not.
In one embodiment, the driver chip 123 is preset with data information for interaction with the detection module 11, and the information obtaining result includes whether the preset data information can be normally obtained from the driver chip 123.
The detection module 11 is further configured to determine whether the head control board 12 is powered on according to whether the data information can be normally acquired from the driving chip 123.
By presetting data information for interaction with the detection module 11 at the driving chip 123, the detection module 11 acquires the preset data information from the driving chip 123 after the driving chip 123 is started. The detection module 11 can determine whether the driving chip 123 is powered on according to whether preset data information can be normally acquired from the driving chip 123, and further can determine whether the head control board 12 is powered on according to whether the driving chip 123 is powered on.
The driver chip 123 and the detection module 11 CAN communicate with each other through communication methods such as UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver Transmitter), IIC (Inter-integrated circuit bus), SPI (SERIAL PERIPHERAL INTERFACE ), CAN (Controller Area Network, controller area network), USB (Universal Serial Bus ), network port, FSMC (Flexible Static Memory Controller, variable static memory controller), and the like.

The display information includes display information indicating that the head control board 12 is powered on when the head control board 12 is powered on, and display information indicating that the head control board 12 is not powered on when the head control board 12 is not powered on.
If the detection module 11 obtains a determination that the head control board 12 is powered on, the detection module 11 generates display information when the head control board 12 is powered on. If the detection module 11 obtains a judgment result that the head control board 12 is not powered on, the detection module 11 generates display information when the head control board 12 is not powered on.
And a display device 14 for displaying the received display information.

After the electronic components of the spray heads are electrified, the information acquisition results of the electronic components of the spray heads can be normal.
Whether the spray head control panel is electrified can be judged according to whether the information acquisition result of the spray head electronic components on each spray head electronic component is normal or not. If the information acquisition result of each nozzle electronic component is normal, the nozzle control board is judged to be electrified. If the information acquisition result of the spray head electronic components on each spray head electronic component is abnormal, judging that the spray head control board is not electrified.
In one embodiment, the head electronics include a head memory and the information acquisition result includes whether the head related information can be normally acquired from the head memory.
Step S1 comprises obtaining relevant information of the spray head from a spray head memory electrically connected with the spray head power supply, and step S2 comprises judging whether the spray head control board is electrified according to whether the information can be normally obtained from the spray head memory.
And the spray head power supply is used for supplying power to all electronic components of the spray head.
The spray head memory is arranged in the spray head and is electrically connected with a spray head power supply and used for storing relevant information of the spray head.
The relevant information of the spray head comprises the model of the spray head, the production date of the spray head, printing information required by printing of the spray head, reference voltage of the spray head and the like. When the spray head storage is normal, after the spray head is started, a processor in the spray head can normally acquire printing information required by printing from the spray head storage and print by utilizing the printing information, so that whether the spray head storage is electrified is related to whether the spray head can normally print, when judging whether the spray head control board is electrified, whether the spray head storage is electrified is needed to be judged, and only the storage of the spray head is normal, and the spray head can normally print.
After the shower nozzle memory is electrified, the relevant information of the shower nozzle can be obtained from the shower nozzle memory. If the nozzle memory is not electrified, the relevant information of the nozzle cannot be acquired from the nozzle memory. Therefore, whether the nozzle memory is powered on can be judged according to whether the related information of the nozzle is acquired from the nozzle memory. Whether the spray head control board is powered on can be judged according to whether the spray head memory is powered on.
In one embodiment, the step S1 of acquiring the relevant information of the spray head from the spray head memory electrically connected with the spray head power supply comprises the steps of sending a plurality of information acquisition signals to the spray head memory after the spray head control board is electrified, and the step S2 of judging whether the spray head control board is electrified according to whether the information can be normally acquired from the spray head memory or not, wherein the step S2 of judging that the information cannot be normally acquired from the spray head memory if any information acquisition information in the plurality of information acquisition signals is not responded and the spray head control board is not electrified.
In step S1, the related information of the spray head is obtained from a spray head memory electrically connected with the spray head power supply, wherein the related information comprises printing information required by printing is obtained from the spray head memory.
In the printing process, a processor of the spray head acquires printing information required by printing from a spray head memory, and prints by utilizing the printing information. Therefore, after the nozzle is started, whether the nozzle control board is electrified can be judged by judging whether the nozzle memory can normally acquire printing information required by printing, so that whether the nozzle can normally print can be judged, and the normal operation of the printing process can be ensured.
In one embodiment, the showerhead electronics includes a temperature sensor and the information acquisition includes whether a temperature signal acquired from the temperature sensor is normal.
In one embodiment, step S1 further comprises acquiring the temperature signal from a temperature sensor arranged inside the spray head and electrically connected with the spray head power supply, and step S2 further comprises judging whether the spray head control board is powered on or not according to whether the temperature signal acquired from the temperature sensor is normal or not.
The temperature sensor is used for detecting the temperature of the spray head control plate. When the spray head control plate is electrified, each spray head electronic component on the spray head control plate can generate heat, so that the temperature of the spray head control plate is increased. When the temperature of the spray head control board is judged to be normal according to the temperature signal acquired by the temperature sensor, the spray head control board can be determined to be electrified.
In one embodiment, the temperature sensor is a thermistor. The thermistor is a resistor whose resistance value changes with a change in external temperature. The temperature signal transmitted by the thermistor to the detector includes a current value through the thermistor. The resistance of the thermistor changes with the external temperature, and the current value passing through the thermistor also changes. The detection module can obtain the temperature of the position of the thermistor by carrying out data conversion on the received current value.
The temperature signal comprises an electrical signal within a set range of values. After the temperature signal is obtained by the detection module, the temperature value is calculated and obtained by using the temperature signal. The value of the temperature signal is too high or too low, and the temperature value obtained by calculation is not in the normal temperature range. If the temperature value obtained by the calculation of the detection module is not in the normal range, the detection module can be judged to not normally obtain the temperature signal, and the temperature sensor can be judged to not normally power up. If the temperature sensor is not normally powered up, the showerhead control plate may not be powered up.
After the spray head is started, all electronic devices in the spray head can operate after being electrified, and heat is continuously generated in the operation process. Therefore, the internal temperature value of the spray head obtained by the detection module according to the received temperature signal is continuously increased and then is in a numerical range. The detection module can further judge whether the spray head control board can be normally used according to the temperature value obtained by the received temperature signal. If the temperature value obtained by the detection module according to the temperature signal is in the set temperature range, the detection module judges that the spray head control board can be normally used. If the temperature value acquired by the detection module according to the temperature signal is not in the set temperature range, the detection module judges that the spray head control panel cannot be normally used. The temperature range is set between 0-60 degrees, the internal temperature of the spray head is higher than 60 degrees, electronic components of the spray head in the spray head can be burnt out, the internal temperature of the spray head is lower than 0 degrees, and the spray head control board can be unpowered.
In one embodiment, the electronic component of the spray head comprises a driving chip, and the information acquisition result comprises whether an electric signal acquired from the driving chip is normal or not.
Step S1 also comprises the step of obtaining the electric signal from a driving chip electrically connected with the nozzle socket, and step S2 also comprises the step of judging whether the nozzle control board is electrified according to whether the electric signal obtained from the driving chip is normal or not.
The electrical signal includes a current or a voltage.
The driving chip is used for driving the electronic components of the spray head control board.
The driving chip is electrically connected with the power supply of the spray head.
After the spray head control board is electrified, the driving chip is in a conducting state with the spray head power supply. By detecting the driving chip, whether the spray head control plate is electrified or not can be judged.
The driving chip is electrically connected with the detection module through pins. The driving chip outputs current or voltage to the detection module after being electrified. If the driving chip does not output current or voltage to the detection module or the output current or power supply is low, the detection module can judge that the driving chip is not electrified, and then judge that a spray head control board comprising the driving chip is not electrified.
And the detection module judges whether the spray head control panel is electrified according to whether the electric signal can be normally acquired from the driving chip.
The electric signal obtained by the detection module from the driving chip is a current signal higher than a first set value or a voltage signal higher than a second set value.
If the current value or the voltage value received by the detection module is lower, the current value or the voltage value received by the detection module may be noise.
The detection module can judge whether the driving chip is electrified or not according to whether the electric signal is received or not, and can judge whether the spray head control board is electrified or not according to whether the driving chip is electrified or not.
In one embodiment, the information acquisition result includes that preset data information can be normally acquired from the driving chip.
Step S1 further comprises the step of obtaining preset data information from the driving chip, and step S2 further comprises the step of judging whether the spray head control board is powered on or not according to the fact that the preset data information can be obtained from the driving chip normally.
The driving chip is preset with preset data information for interacting with the detection module;
The detection module is further used for judging whether the spray head control board is electrified according to whether preset data information can be normally acquired from the driving chip.
The detection module acquires preset data information from the driving chip after the driving chip is started by presetting the preset data information for interaction with the detection module. The detection module judges whether the driving chip is electrified according to whether preset data information can be normally obtained from the driving chip or not, and further judges whether the spray head control board is electrified according to whether the driving chip is electrified or not.
The driver chip and the detection module CAN communicate with each other through communication modes such as UART (Universal Asynchronous Receiver/Transmitter, universal asynchronous receiver Transmitter), IIC (Inter-Integrated Circuit bus), SPI (SERIAL PERIPHERAL INTERFACE ), CAN (Controller Area Network, controller area network), USB (Universal Serial Bus ), network interface, FSMC (Flexible Static Memory Controller, variable static memory controller) and the like.
In one embodiment, the step S1 comprises acquiring information from at least two nozzle electronic components powered by the nozzle power supply, and the step S2 comprises judging that the nozzle control board is not powered on if the information acquisition result of any nozzle electronic component in the nozzle electronic components is abnormal.
The head control board may be provided with a plurality of head electronic parts for supporting the head to normally operate. Only after the electronic components of each spray head are electrified normally, the spray head can work normally. Therefore, before the nozzle starts to work, information needs to be acquired from a plurality of nozzle electronic components arranged on the nozzle control board, whether the nozzle control board is electrified is judged according to the information acquisition result of each nozzle electronic component, if the information acquisition result of each nozzle electronic component by the nozzle electronic component is abnormal, the nozzle electronic component may not be electrified, in the printing process, the nozzle electronic component may not work normally, and the normal use of the nozzle may be affected by the abnormal work of the nozzle electronic component, so in the detection process, if the information acquisition result of any nozzle electronic component in each nozzle electronic component is abnormal, the nozzle control board is judged not to be electrified.
One of the reasons why the head control board is not powered on is that the head control board is not normally connected with the head power supply. After the user can obtain the information that the shower nozzle control panel was not electrified, detect whether shower nozzle control panel and shower nozzle power are normally connected, if detect shower nozzle control panel and shower nozzle power and not normally connect, then the user can connect shower nozzle control panel and shower nozzle power again to ensure that each shower nozzle electronic component can normally electrified.
In one embodiment, if the detection module cannot normally acquire information from any one of the head memory, the temperature sensor provided on the head control board, and the driving chip for driving each electronic component of the head, it is determined that the head control board is not powered on.
And the spray head memory is used for storing printing information required by spray head printing. Only after information can be normally acquired from the head memory, it can be judged that the head memory can be normally used. Only after the nozzle memory is normally used, the nozzle can acquire the information required by printing from the nozzle memory in the printing process, so that the printing can be smoothly performed.
The temperature sensor is used for measuring the internal temperature of the spray head and can measure the temperature of the spray head in real time in the working process of the spray head. Whether the shower nozzle control board is electrified can be judged according to whether the temperature signal obtained from the temperature sensor is normal or not. If the temperature signal obtained from the temperature sensor is abnormal, it can be judged that the spray head control board is not electrified normally, and the spray head is abnormal, so that the printing operation is not suitable. Only after the temperature signal obtained from the temperature sensor is normal, the printing process of the spray head can be guaranteed not to be in accident, the spray head can be judged to be started normally, and the follow-up operation can be carried out.
And the driving chip is used for driving the electronic components of the spray head. Whether the electronic components of the spray head can work normally or not relates to whether the spray head can operate or not. Therefore, whether the driving chip is normal or not directly determines whether the spray head can perform subsequent operation or not. After the spray head is started, whether the driving chip is normal needs to be judged first, if the driving chip is abnormal, the spray head control board can be judged that the spray head control board is not electrified, the spray head cannot perform subsequent printing, and the spray head is failed to start.
Therefore, only after signals can be normally acquired from the spray head memory, and information acquired from the temperature sensor inside the spray head and the driving chip for driving the electronic components inside the spray head are normal, the spray head control board can be judged to be electrified, and the spray head can work normally. Only after the power-on of the spray head control board is judged according to the spray head memory, the temperature sensor in the spray head and the driving chip for driving the electronic components in the spray head, the power-on of the spray head control board can be finally judged, and the spray head can be used for carrying out subsequent operation.
