Description

Technical Field

[0001] This utility model relates to, specifically to, a valve control system for preventing indoor gas leaks. Background Technology

[0002] Currently, indoor gas leak protection mainly relies on mechanical self-closing valves or gas alarm-linked solenoid valves, among which:

[0003] Mechanical self-closing valves (such as flow sensing valves and overcurrent protection valves): automatically cut off the gas supply by detecting abnormal gas flow (such as pipeline rupture), but cannot detect minor leaks after the gas appliance is properly shut off (such as the valve not being completely closed after the stove is turned off).

[0004] Gas alarm linked solenoid valve: When the gas concentration exceeds the standard, the alarm triggers the solenoid valve to cut off the gas supply. However, this is a passive protection and has a response lag (requires a certain concentration to accumulate). It also cannot solve the problem of minor leaks caused by the valve not being shut off synchronously after the gas appliance is turned off.

[0005] Disadvantages of existing technology:

[0006] Lack of active synchronization control: Existing technologies do not link with the working status of gas appliances (stoves, water heaters) in real time. After the gas appliance is turned off, the pipeline valve remains open, relying on manual closing or passive shut-off after a leak occurs, which poses a safety hazard.

[0007] Risk of misjudgment: Mechanical valves are prone to being accidentally triggered and closed due to fluctuations in normal gas flow; alarms are easily affected by kitchen fumes and steam, leading to false alarms or missed alarms.

[0008] Unable to prevent minor leaks: After the gas appliance is turned off, the pipeline from the valve to the burner may leak slowly due to valve aging or foreign object blockage. Current technology is unable to detect such low-concentration leaks. Utility Model Content

[0009] The purpose of this invention is to provide an indoor gas leak prevention valve control system that determines the actual start-up and shutdown status of gas equipment solely by detecting the ignition status of the gas burner, resulting in more accurate and real-time detection results.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] An indoor gas leak prevention valve control system includes a gas pipeline, a gas appliance, and an integrated microprocessor. The gas pipeline has a normally closed solenoid valve connected to its inlet end, and the gas appliance is connected to its end end. The integrated microprocessor is electrically connected to the normally closed solenoid valve and to a mains power supply. The gas appliance's burner is equipped with a spark detector electrically connected to the integrated microprocessor. The gas appliance also has a signal transmitter electrically connected to the spark detector and a wireless receiver electrically connected to the integrated microprocessor. The gas appliance is either a gas stove or a water heater.

[0012] Specifically, the valve control system is equipped with a gas stove and a water heater. One end of the gas pipeline is connected to the gas stove, and the other end of the gas pipeline is connected to the water heater. Both the burners of the gas stove and the water heater are equipped with spark detectors.

[0013] Specifically, both the gas stove and the water heater are equipped with signal transmitters, and each spark detector is electrically connected to the corresponding signal transmitter.

[0014] Specifically, both the gas stove and the water heater are equipped with a wireless receiver, which is electrically connected to an integrated microprocessor.

[0015] Specifically, the wireless receiver is a Wi-Fi / Bluetooth / ZigBee receiver.

[0016] Specifically, the wireless receiver contains a lithium battery.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By linking wireless and wired control modes, it is more reliable and more resistant to interference than control by a single mechanical structure or sensor. Through bidirectional signal transmission (such as wireless radio frequency, Bluetooth or hard-wired connection) between the gas appliance and the normally closed solenoid valve 1, strict synchronization between valve opening and closing and gas appliance ignition status is achieved, realizing millisecond-level response.

[0019] 2. By detecting the ignition status of the gas burner, the actual start-up and shutdown status of the gas equipment can be determined. The detection results are more accurate and real-time, avoiding the problem of mechanical self-closing valves failing to detect minute leaks, and also avoiding the response lag problem of gas alarm linkage solenoid valves.

[0020] 3. When the gas equipment is turned off, the normally closed solenoid valve 1 will close automatically, eliminating the risk of residual gas leakage from the valve to the burner section.

[0021] 4. Use the ignition status of the gas appliance burner as the criterion to avoid false alarms or missed alarms caused by kitchen fumes and steam.

[0022] 5. Supports remote monitoring and multi-device management, and is compatible with the smart home ecosystem. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] See Figure 1 , Figure 2 An indoor gas leak prevention valve control system includes a gas pipeline 2, a gas appliance, and an integrated microprocessor 4a. A normally closed solenoid valve 1 is connected to the gas inlet end of the gas pipeline 2, and the gas appliance is connected to the end end of the gas pipeline 2. The integrated microprocessor 4a is electrically connected to the normally closed solenoid valve 1. The integrated microprocessor 4a is connected to a mains power supply 4c.

[0030] The burner of the gas appliance (such as water heater 3a, gas stove 3b) is equipped with a spark detector 5a, which is connected to an integrated microprocessor 4a via a signal line 6. The gas appliance also contains a signal transmitter 5b, which is electrically connected to the spark detector 5a. Furthermore, the gas appliance contains a wireless receiver 4b, which is connected to the integrated microprocessor 4a via the signal line 6. The gas appliance is either a gas stove 3b or a water heater 3a.

[0031] Specifically, the valve control system includes a gas stove 3b and a water heater 3a. One end of the gas pipeline 2 is connected to the gas stove 3b, and the other end of the gas pipeline 2 is connected to the water heater 3a. Both the burners of the gas stove 3b and the water heater 3a are equipped with spark detectors 5a.

[0032] Specifically, both the gas stove 3b and the water heater 3a are equipped with signal transmitters 5b, and each spark detector 5a is electrically connected to the corresponding signal transmitter 5b.

[0033] Specifically, both the gas stove 3b and the water heater 3a are equipped with a wireless receiver 4b, which is connected to the integrated microprocessor 4a via a signal line 6.

[0034] Specifically, the wireless receiver 4b is a Wi-Fi / Bluetooth / ZigBee receiver, and the wireless receiver 4b contains a lithium battery.

[0035] This invention can operate in two modes: wireless control and wired control. The wireless control mode is as follows:

[0036] When the spark detector 5a detects the ignition (spark) of the burner of the gas appliance (water heater 3a or gas stove 3b), the spark detector 5a sends a signal to the signal transmitter 5b, which then sends a signal. The wireless receiver 4b receives this signal and sends it back to the integrated microprocessor 4a via the signal line 6. The integrated microprocessor 4a then sends a signal to the normally closed solenoid valve 1, causing it to open and allowing gas to reach the burner.

[0037] Wired control mode:

[0038] When the spark detector 5a detects that the burner of the gas appliance (water heater 3a or gas stove 3b) is ignited (generating a spark), the spark detector 5a feeds back to the integrated microprocessor 4a through the signal line 6. The integrated microprocessor 4a feeds back to the normally closed solenoid valve 1, causing the normally closed solenoid valve 1 to open, allowing the gas to reach the burner.

[0039] The technical effects of this utility model are as follows:

[0040] 1. By linking wireless and wired control modes, it is more reliable and more resistant to interference than control by a single mechanical structure or sensor. Through bidirectional signal transmission (such as wireless radio frequency, Bluetooth or hard-wired connection) between the gas appliance and the normally closed solenoid valve 1, strict synchronization between valve opening and closing and gas appliance ignition status is achieved, realizing millisecond-level response.

[0041] 2. By detecting the ignition status of the gas burner, the actual start-up and shutdown status of the gas equipment can be determined. The detection results are more accurate and real-time, avoiding the problem of mechanical self-closing valves failing to detect minute leaks, and also avoiding the response lag problem of gas alarm linkage solenoid valves.

[0042] 3. When the gas equipment is turned off, the normally closed solenoid valve 1 will close automatically, eliminating the risk of residual gas leakage from the valve to the burner section.

[0043] 4. Use the ignition status of the gas appliance burner as the criterion to avoid false alarms or missed alarms caused by kitchen fumes and steam.

[0044] 5. Supports remote monitoring and multi-device management, and is compatible with the smart home ecosystem.
