[0024] Figure 1 This is a structural diagram of an intelligent valve provided in an embodiment of this utility model. Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish different objects, not to limit a specific order. The various embodiments of this utility model described below can be performed individually, or they can be combined with each other; this utility model does not impose specific limitations in this regard.

[0027] Figure 1 This is a structural diagram of an intelligent valve provided in an embodiment of this utility model.

[0028] like Figure 1 As shown, the smart valve 10 is connected in the gas pipeline 21 between the gas stove 20 and the gas meter 30. The smart valve 10 includes a human body recognition module 11 and a valve control module 12.

[0029] The human body recognition module 11 is installed at the gas stove 20 and is electrically connected to the valve control module 12 to detect in real time whether there are people in front of the gas stove 20.

[0030] The valve control module 12 is configured to control the smart valve 10 to shut off when the human body recognition module 11 recognizes that no one is in front of the gas stove 20 within a set time period.

[0031] Specifically, the human body recognition module 11 can monitor in real time whether there are people in front of the gas stove 20. When it is detected that no one operates in front of the gas stove 20 within a set time, the valve control module 12 will close the smart valve in time to avoid the situation where people leave the gas stove but forget to turn off the flame, effectively ensuring the safety of people using gas.

[0032] Specifically, the human body recognition module 11 can be electrically connected to the valve control module 12 via a wired connection or via a wireless connection; no specific limitation is made here.

[0033] This invention, by incorporating a human body recognition module, can detect in real time whether no one is in front of the gas stove for an extended period of time. When no one is detected within a set time, the intelligent valve is shut off via the valve control module. This solves the technical problem in existing gas stoves where the inability to automatically detect whether the stove has been left on for an extended period of time and thus shut off the valve poses a safety hazard. This invention achieves the technical effect of avoiding safety hazards and ensuring the safe use of the gas stove.

[0034] Optionally, the human body recognition module 11 includes at least one of the following: an infrared sensing submodule, an image recognition submodule, and a camera submodule.

[0035] Specifically, the human body recognition module 11 can be configured as an infrared sensing submodule using infrared sensing technology, an image recognition submodule using image recognition technology, or a camera submodule using video recognition technology, etc., as needed. Among them, the infrared sensing submodule has the advantages of low power consumption, small size, low cost, and high recognition accuracy. Therefore, considering cost, the infrared sensing submodule is preferred.

[0036] Optionally, such as Figure 1 As shown, the smart valve also includes a pressure sensor 13; the pressure sensor 13 is electrically connected to the valve control module 12; the pressure sensor 13 monitors the pressure changes in the gas pipeline 21 in real time.

[0037] Valve control module 12 is also configured as follows:

[0038] The pressure change occurs when the pressure inside the pipe decreases to the first pressure value within the first time period, and the human body recognition module 11 recognizes that there is someone in front of the gas stove 20, then the smart valve is opened.

[0039] Alternatively, if the pressure changes and the pressure inside the pipe stabilizes within a first preset range within a second time period, and the human body recognition module 11 detects that no one is in front of the gas stove 20 within the second time period, then the intelligent valve is controlled to shut off.

[0040] Optionally, the valve control module 12 includes a timer; the timer is used to time pressure changes monitored by the pressure sensor 13.

[0041] Specifically, when the gas stove 20 is turned off, residual gas remains in the gas pipeline 21, keeping the pressure in the gas pipeline 21 relatively constant. When the gas stove 20 is turned on, the gas in the gas pipeline 21 near the gas stove 20 is quickly released, indicating that the gas stove 20 is now ready for use. The pressure sensor 13 can detect that the pressure in the pipeline rapidly decreases to a first pressure value within a first duration, which is an extremely short instantaneous value that can be recorded by a timer. If the human body recognition module 11 detects that someone is in front of the gas stove 20, the valve control module 12 controls the smart valve 10 to open based on the monitored pressure change, allowing the gas stove 20 to be used normally when someone is present.

[0042] During normal use of the gas stove 20, the pressure in the gas pipeline 21 remains relatively constant, meaning that the pressure within the pipeline remains stable within the first preset range for the second time period. If the human body recognition module 11 detects that no one is in front of the gas stove 20 during the second time period, it indicates that no one is present and the gas stove 20 has been left on. At this time, the valve control module 12 controls the smart valve 10 to shut off based on the monitored pressure changes, thus cutting off the gas supply in a timely manner and avoiding safety hazards. The second time period can be set to tens of minutes or several hours as needed, and is specifically recorded by a timer.

[0043] Optionally, the valve control module 12 is also configured to transmit alarm information to the host computer via the wireless transmission module 11 when it detects that no one is present before the gas stove 20 is activated and shuts off the smart valve 10.

[0044] Specifically, when the valve control module 12 identifies, through the pressure sensor 13 and the human body recognition module 11, that the pressure inside the pipe has stabilized within the first preset range during the second time period, and that no one is in front of the gas stove 20 during the second time period, it will shut off the smart valve 10 and simultaneously send an alarm message to the host computer, reminding the gas stove 20 that it has been unattended for a long time and that the flame has been left on, so that the personnel on the host computer can promptly turn off the gas stove 20 and ventilate to eliminate safety hazards. At this time, the host computer can be a mobile communication device for the user of the gas stove 20, or it can be a remote server, which can provide prompts to the user through an APP (Application) pre-bound to the gas stove 20.

[0045] Optionally, such as Figure 1 As shown, the smart valve also includes a self-test module 14; the self-test module 14 is electrically connected to the valve control module 12; the self-test module 14 is used to detect whether the smart valve has a fault.

[0046] Specifically, the self-test module 14 can detect whether the smart valve has any faults in real time. When it detects that the smart valve has faults such as insufficient power, inability to open, inability to close, or inability to connect to the human body recognition module 11, the self-test module 14 will send a fault command to the valve control module 12, so that the valve control module 12 can use the wireless transmission module 15 to alarm the host computer based on the fault command, or control the alarm module to issue an alarm prompt based on the fault command.

[0047] Optionally, such as Figure 1 As shown, the smart valve also includes a wireless transmission module 15; the wireless transmission module 15 is electrically connected to the valve control module 12.

[0048] The valve control module 12 is also configured to report the fault information to the host computer via the wireless transmission module 15 when the self-test module 11 detects that the smart valve is faulty.

[0049] Specifically, the host computer can be a remote server or a mobile communication device used by designated personnel. When the self-test module 14 detects a fault in the smart valve, it sends a fault command to the valve control module 12, causing the valve control module 12 to report the fault information to the host computer based on the fault command. After receiving the fault information, the host computer can promptly notify maintenance personnel to arrange subsequent maintenance matters. This improves the after-sales service of the gas stove 20, speeds up the after-sales response, and effectively enhances the supervision of gas usage safety.

[0050] Optionally, such as Figure 1 As shown, the smart valve also includes a power supply module 16; the power supply module 16 is used to supply power to the smart valve.

[0051] Specifically, the power supply module 16 can be a replaceable battery, a rechargeable battery, or a power supply module connected to AC power; no specific restrictions are made here.

[0052] Optionally, such as Figure 1 As shown, the smart valve also includes an alarm module 17; the alarm module 17 is electrically connected to the valve control module 12; the alarm module 17 is used to issue an alarm prompt under the control of the valve control module 12.

[0053] Specifically, the alarm module 17 can be an indicator light, buzzer, or other device. When the valve control module 12 detects a fault in the smart valve 10 through the self-test module 15, or when the pressure sensor 13 and the human body recognition module 11 detect that no one is present and the gas stove has been left on, an alarm will be issued to directly and quickly notify the user that there is a problem with the gas stove 20 and that it needs to be investigated and resolved.

[0054] In this embodiment of the invention, by using the intelligent valve provided by this embodiment, not only are the safety hazards of self-closing valves in the prior art improved, but also the valve can be opened in time to supply gas when gas is needed and effectively cut off gas when not in use by utilizing infrared human body sensing (or image monitoring, video monitoring, etc.) and pipeline pressure monitoring. This improves gas safety for users and enhances the operational quality of gas stove manufacturers and gas suppliers, effectively avoiding losses caused by safety issues.
