Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] This utility model discloses an automatic ignition gas product control system, such as... Figure 1-8 As shown, it includes: a gas supply device 10, a controller 20 and an igniter 30. The gas supply device 10 and the burner head 40 are connected by a pipeline with a solenoid valve 50 and a stepper motor valve 60. The gas supply device 10 is used to supply gas to the burner head 40. The solenoid valve 50 and the stepper motor valve 60 are both used to control the gas flow rate supplied by the gas supply device 10 to the burner head 40.

[0032] The controller 20 is used to control the working status of the solenoid valve 50, the stepper motor valve 60 and the igniter 30, and the ignition needle 31 of the igniter 30 is used to ignite the gas in the burner head 40.

[0033] It should be noted that the automatic ignition gas product control system provided by this utility model uses both the solenoid valve 50 and the stepper motor valve 60 to control the gas flow rate supplied by the gas supply device 10 to the burner head 40, and the ignition needle 31 of the igniter 30 is used to ignite the gas in the burner head 40, thus realizing automatic ignition of the gas product. Therefore, the automatic ignition gas product control system provided by this utility model solves the technical problem of inaccurate gas flow control in the prior art.

[0034] like Figure 1 and Figure 2 As shown, the gas supply device 10 is sequentially connected to a manual valve 70 and a pressure reducing valve 80 via pipelines. It should be noted that the provision of the manual valve 70 and the pressure reducing valve 80 allows for pressure reduction of the gas supplied to the gas supply device 10.

[0035] like Figure 1 and Figure 2 As shown, the pressure reducing valve 80, the solenoid valve 50, and the stepper motor valve 60 are connected in sequence via pipelines, or the pressure reducing valve 80, the stepper motor valve 60, and the solenoid valve 50 are connected in sequence via pipelines.

[0036] like Figure 1-8 As shown, the controller 20 is electrically connected to a temperature sensing rod 90 for detecting food temperature or ambient temperature. It should be noted that the temperature sensing rod 90 functions as a temperature sensor and can detect either food temperature or ambient temperature.

[0037] like Figure 1 and Figure 2 As shown, the controller 20 is electrically connected to a flame detection device 100 for detecting the flame of the burner head 40.

[0038] like Figure 1 and Figure 2As shown, the flame detection device 100 is a thermocouple or an ionizing needle. It should be noted that, since the flame detection device 100 is a thermocouple or an ionizing needle, the flame temperature of the burner head 40 can be detected, which facilitates temperature adjustment.

[0039] like Figure 3 and Figure 4 As shown, the controller 20 includes at least two main control chips, which communicate via serial port. The main control chips are electrically connected to a temperature detection module, a food temperature detection module, an ambient temperature detection module, a knob, and buttons. In this embodiment, the use of at least two main control chips can improve the reliability of the control system and make ignition safer.

[0040] The temperature detection module is used to detect the temperature inside the burner head 40, the food temperature detection module is used to detect the temperature of the food, the ambient temperature detection module is used to detect the external ambient temperature of the burner head 40, and the knob and button are used to control the ignition of the igniter 30.

[0041] like Figure 3 and Figure 4 As shown, the main control chip is electrically connected to a Bluetooth / WIFI module, a remote control receiver module, and a voice recognition module. In this embodiment, the user can control the flame size or close the stepper motor valve 60 via a knob, button, mobile APP, remote control, or voice recognition.

[0042] The control process of stepper motor valve 60 is as follows: When adjusting the temperature, the stepper motor is first reset. The system PID adjusts the stepper motor speed according to the user-selected temperature. When approaching 65% of the target temperature, the speed decreases, decreasing by one speed for every 5% increase in target temperature, until 100% of the target temperature is reached. Once the target temperature is reached, the temperature is maintained at a constant level. Each speed is detected by a photoelectric switch to ensure the correct speed is selected. If the photoelectric switch detects an incorrect speed, the system PID resets the stepper motor and adjusts it to the correct speed to continue temperature control.

[0043] Working Principle: The automatic ignition gas product control system provided by this utility model uses both solenoid valve 50 and stepper motor valve 60 to control the gas flow rate supplied by the gas supply device 10 to the burner head 40. The ignition needle 31 of the igniter 30 is used to ignite the gas in the burner head 40, thus realizing automatic ignition of the gas product. Therefore, the automatic ignition gas product control system provided by this utility model solves the technical problem of inaccurate gas flow control in the prior art.

[0044] In practice, the user opens the manual valve 70, and the gas passes through the pressure reducing valve 80 (canned gas usually needs to be depressurized, while piped gas generally does not need to be depressurized again). The user confirms by rotating the knob, pressing the button, using the mobile APP, remote control, or voice recognition to open the corresponding burner head 40, which automatically ignites the gas. The controller 20 opens the stepper motor valve 60 and the solenoid valve 50, and the flame is automatically maintained after successful ignition. The flame size (temperature control) or flame can be controlled or turned off by the knob, button, mobile APP, remote control, or voice recognition.

[0045] The controller 20 is powered by 85VAC to 265VAC mains power, a battery, or a generator via a circuit conversion. When mains power is available, it is converted to power the system; when mains power is unavailable, it is powered by the battery; after successful ignition, the generator generates electricity normally, and the system switches to power from the generator.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
