Description

Technical Field

[0001] This utility model relates to the field of hazardous gas leak control, and in particular to a hazardous gas leak interlock control device. Background Technology

[0002] Natural gas is a dangerous gas that we use frequently in our daily lives, so it is essential to detect leaks during its use. In particular, natural gas and coal gas are often left on, and leaks can cause many safety accidents.

[0003] Existing gas stoves typically feature a timer-off switch for automatic gas shut-off. However, users often need to manually turn on the timer, which is inconvenient, especially during busy cooking sessions when users may forget to turn it off, leading to safety hazards. Furthermore, some gas valves on the market are equipped with electric shut-off switches for automatic gas flow control. However, these electric switches usually rely on battery power; if the battery is low or fails, the switch will malfunction, affecting the safe shut-off of gas. This battery-dependent design also presents inconvenience in practical use, requiring users to regularly check and replace batteries, increasing maintenance costs and operational complexity. Therefore, this solution proposes a hazardous gas leak interlock control device to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a hazardous gas leak interlock control device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hazardous gas leak interlock control device, comprising:

[0006] A 4G receiver control module, wherein the 4G receiver control module is used for communication control;

[0007] A combustible gas leak detector is electrically connected to a 4G receiver control module and is installed at the hazardous gas transport path. The combustible gas leak detector is used for detecting hazardous gas leaks.

[0008] An explosion-proof solenoid valve is installed at the pipeline for conveying hazardous gases and is communicatively connected to a 4G receiving and control module.

[0009] A sensing component, which is electrically connected to a 4G receiver control module, is used for human body sensing.

[0010] Preferably, the connection terminal of the 4G receiving control module is provided with an input terminal, a signal terminal, and a control output terminal. The signal terminal is electrically connected to the communication terminal of the combustible gas leak detector, the input terminal is electrically connected to the power supply terminal of the combustible gas leak detector, and the control output terminal is electrically connected to the control terminal of the explosion-proof solenoid valve.

[0011] Preferably, a power supply unit is provided between the input terminal and the power supply terminal of the combustible gas leak detector, and the power supply unit is used to power the device.

[0012] Preferably, the power supply unit is provided with a DC L terminal and a DC N terminal. The DC L terminal is electrically connected to the input terminal and the input L live wire of the combustible gas leak detector, and the DC N terminal is electrically connected to the input terminal and the loop N neutral wire of the combustible gas leak detector.

[0013] Preferably, the 4G receiver control module is provided with:

[0014] A timing module is used to send on / off signals at regular intervals;

[0015] The control unit is electrically connected to the control terminal of the timing module, and is used to set the timing data in the timing module.

[0016] Preferably, the 4G receiving control module is further provided with a 4G communication module, which is used for the wireless communication connection of the 4G receiving control module.

[0017] Preferably, the sensing component includes a trigger switch for detecting human body signals, and the output terminal of the trigger switch is electrically connected to the signal receiving terminal of the 4G receiving control module.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] (1) This utility model connects and sets up a 4G receiving control module, a combustible gas leak detector and an explosion-proof solenoid valve. When the natural gas or coal gas is left on, the combustible gas leak detector will detect and trigger the leak and transmit the signal to the 4G receiving control module. The 4G receiving control module will then transmit the signal to the explosion-proof solenoid valve to close the explosion-proof solenoid valve and prevent danger.

[0020] (2) When natural gas and coal gas are needed, the sensing component detects the presence of a human body and the gas can be used normally. When the human body leaves, the sensing component can no longer detect the human body and transmits the signal to the 4G receiving and control module. The 4G receiving and control module transmits the signal to the explosion-proof solenoid valve and closes the explosion-proof solenoid valve.

[0021] (3) This utility model, through the combined design of a 4G receiving control module, a combustible gas leak detector, an explosion-proof solenoid valve and a sensing component, can not only detect dangerous gas leaks in real time and control the explosion-proof solenoid valve to shut off the dangerous gas supply, but also control the opening and closing of the explosion-proof solenoid valve according to human body induction. This makes the device more flexible in controlling the dangerous gas supply and locking. The entire device can be connected to the circuit, eliminating the need for manual operation and frequent power replacement. Therefore, this device is more convenient and stable to use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: This utility model provides the following... Figure 1 The hazardous gas leak interlock control device shown includes:

[0026] 4G receiver control module 1 is used for communication control. The connection end of 4G receiver control module 1 is provided with input terminal 101, signal terminal 102 and control output terminal 103.

[0027] Specifically, the 4G receiver control module 1 is equipped with:

[0028] Timing module 104 is used to send on / off signals at regular intervals;

[0029] Control unit 105 is electrically connected to the control terminal of timing module 104 and is used to set timing data at timing module 104.

[0030] It should be noted that the timing module 104 is integrated into the control circuit of the 4G receiver control module 1. It can periodically execute the shutdown command according to the time interval set by the user. The command is dispatched through the 4G receiver control module 1. The control unit 105 can edit the clock logic to define the timing time and thus realize the timing setting.

[0031] Furthermore, the 4G receiver control module 1 is also equipped with a 4G communication module, which is used for the wireless communication connection of the 4G receiver control module 1.

[0032] It should be noted that the 4G communication module supports 4G network communication and can exchange data with mobile applications. In this solution, the user connects to the device's 4G connection module through the mobile phone, and the 4G receiving control module 1 receives control commands sent by the mobile phone through the 4G communication module. Under this operation setting, the control of this solution can be achieved by the mobile phone.

[0033] Combustible gas leak detector 2 is electrically connected to 4G receiver control module 1 and is installed at the hazardous gas transport path. Combustible gas leak detector 2 is used for hazardous gas leak detection. Signal terminal 102 is electrically connected to communication terminal of combustible gas leak detector 2 and input terminal 101 is electrically connected to power supply terminal of combustible gas leak detector 2.

[0034] It should be noted that the combustible gas leak detector 2 is placed near the stovetop of the gas stove to facilitate and quickly detect combustible gas leaks. At the same time, the monitoring information is transmitted to the 4G receiving and control module 1 via signal transmission. The 4G receiving and control module 1 controls the opening and closing of the explosion-proof solenoid valve 3 based on the received leak signal (yes or no). If the leak signal is yes, the explosion-proof solenoid valve 3 is closed; if the leak signal is no, the explosion-proof solenoid valve 3 is not controlled.

[0035] Specifically, a power supply unit 5 is provided between the input terminal 101 and the power supply terminal of the combustible gas leak detector 2. The power supply unit 5 is used to supply power to the device. By setting the power supply unit 5, the device can be electrically connected in series with the circuit, thereby avoiding the need for frequent power replacement operations of other existing devices.

[0036] Furthermore, the power supply unit 5 is provided with a DC L terminal 501 and a DC N terminal 502. The DC L terminal 501 is electrically connected to the input L live wire of the input terminal 101 and the combustible gas leak detector 2, and the DC N terminal 502 is electrically connected to the circuit N neutral wire of the input terminal 101 and the combustible gas leak detector 2.

[0037] Explosion-proof solenoid valve 3 is installed at the pipeline for conveying hazardous gas. Explosion-proof solenoid valve 3 is communicatively connected to 4G receiving and control module 1. Control output terminal 103 is electrically connected to the control terminal of explosion-proof solenoid valve 3. Explosion-proof solenoid valve 3 is connected in series at the outlet pipeline for conveying hazardous gas to control the on / off of exhaust.

[0038] The sensing component is electrically connected to the 4G receiver control module 1 and is used for human body sensing.

[0039] Specifically, the sensing component includes a trigger switch 4, which is used to detect human body signals. The output terminal of the trigger switch 4 is electrically connected to the signal receiving terminal of the 4G receiving control module 1.

[0040] It should be noted that the trigger switch 4 can use a dual-technology human body sensor, which uses infrared and microwave composite detection to detect human bodies in hazardous gas environments, thereby determining whether someone is operating the device.

[0041] Example 2: When performing a hazardous gas leak interlock control operation, a hazardous gas leak interlock control device disclosed in Example 1 is used;

[0042] When in use, the explosion-proof solenoid valve 3 is installed on the hazardous gas outlet pipe, and other components are installed near the stove body. When a hazardous gas leak occurs, the combustible gas leak detector 2 detects the gas leak and transmits the leak signal to the 4G receiving and control module 1. The 4G receiving and control module 1 transmits the signal to the explosion-proof solenoid valve 3, which closes the explosion-proof solenoid valve 3 and shuts off the hazardous gas to prevent danger.

[0043] When cooking, the trigger switch 4 senses the presence of a human body, and the gas can be used normally. When the human body leaves, the trigger switch 4 can no longer sense the human body, and the trigger switch 4 transmits the signal to the 4G receiving and control module 1. The 4G receiving and control module 1 transmits the signal to the explosion-proof solenoid valve 3, which closes the explosion-proof solenoid valve 3, thus closing the dangerous gas flow path and preventing danger.

[0044] The 4G receiver control module 1 has a timing module 104. The 4G receiver control module 1 transmits a shutdown signal to the explosion-proof solenoid valve 3 at regular intervals through the timing module 104, thereby closing the explosion-proof solenoid valve 3 at regular intervals and closing the dangerous gas flow path to prevent danger.

[0045] Alternatively, a mobile phone can be used to connect to the 4G receiving and control module 1 via the 4G communication module, and remotely control the 4G receiving and control module 1 to close the explosion-proof solenoid valve 3 to prevent danger.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
