Description

Technical Field

[0001] This utility model belongs to the field of gas safety use technology, specifically relating to a gas safety linkage component. Background Technology

[0002] Gas stoves and range hoods are indispensable kitchen appliances in people's daily cooking. Gas stoves use gas as heating fuel, and their use carries certain safety risks. In the event of a gas leak, it may cause serious accidents such as fires and explosions, posing a huge threat to the lives and property of residents.

[0003] To detect gas leaks promptly, residents typically install gas alarms in their kitchens. While these alarms sound an alarm when a leak is detected, alerting residents to potential danger, this function alone is insufficient. When residents are not home or are in noisy environments and do not hear the alarm, the leaked gas continues to spread, accumulating danger. Even if residents hear the alarm, they may still be at risk if they cannot reach the kitchen in time to shut off the gas valve due to emergencies. Furthermore, gas alarms cannot directly stop the gas leak at its source. Therefore, many homes also have robotic arms connected to the gas alarms. These robotic arms work in tandem with the alarms; once the alarm detects a leak and sends a signal, the robotic arm responds quickly, automatically turning the control valve on the gas pipeline to precisely and promptly cut off the gas supply, eliminating the danger posed by the leak at its source.

[0004] However, modern home renovations increasingly prioritize aesthetics. Current wired connections between robotic arms and gas alarms require wiring along walls, cabinets, and other complex structural elements during installation. This not only exposes numerous cables, disrupting the overall harmony and tidiness of the renovation and making the kitchen appear cluttered, but also presents significant challenges when retrofitting in already renovated homes. Concealing cables may require wall drilling and grooving, consuming considerable manpower and resources and potentially damaging the building structure. Furthermore, over time, cables may age and wear, affecting communication stability, and cable replacement involves another cumbersome process and further aesthetic disruption. Therefore, traditional wired connections are no longer sufficient to meet the modern family's desire for a balance between gas safety and home aesthetics. Utility Model Content

[0005] This utility model provides a gas safety linkage component, which aims to improve the existing robotic arms used to shut off gas valves by using wired connection methods, which leads to inconvenient wiring and difficulty in meeting the dual requirements of gas safety and home aesthetics.

[0006] This utility model is implemented as follows: According to one aspect of this utility model, a robotic arm is provided, including a drive mechanism and an actuator. The drive mechanism includes a drive motor, which drives the actuator to rotate in a circular motion, thereby switching the actuator between a first position state and a second position state, wherein the first position state is the initial position state.

[0007] The actuator has a limiting structure that cooperates with the valve handle. When the actuator switches from the first position state to the second position state, the limiting structure of the actuator drives the handle of the valve installed on the gas inlet pipe to rotate, thereby closing the valve. When the actuator switches from the second position state to the first position state, the limiting structure of the actuator drives the handle of the valve installed on the gas inlet pipe to rotate in the opposite direction, thereby opening the valve.

[0014] Furthermore, the lower end of the output shaft is provided with a threaded rod portion, on which a first fixing bolt is installed. The actuator includes an actuator plate, one end of which is sleeved on the output shaft and fixed to the output shaft by the first fixing bolt.

[0015] Furthermore, the other end of the execution plate is provided with two sets of mounting holes, each set of mounting holes including multiple mounting holes arranged sequentially along the length direction of the execution plate, and the two sets of mounting holes are arranged along the width direction of the execution plate; the limiting structure is a limiting post installed in the mounting hole, the limiting post being threaded in the mounting hole, or installed in the mounting hole by a second fixing bolt.

[0016] Furthermore, the mounting assembly includes a mounting base and two symmetrically arranged clamping plates. Each clamping plate includes an upper straight plate, an arc-shaped plate, and a lower straight plate. The upper and lower straight plates are respectively provided with an upper clamping connection hole and a lower clamping connection hole. The upper straight plates of the two clamping plates are mounted on the mounting base via a first clamping bolt and nut assembly. The arc-shaped plates of the two clamping plates clamp onto the gas pipe. The lower straight plates of the two clamping plates are connected via a second clamping bolt and nut assembly. The bottom wall of the housing is provided with a connecting groove that matches the upper end of the mounting base. The upper end of the mounting base is inserted into the connecting groove. Both ends of the mounting base are provided with assembly through holes that penetrate the mounting base vertically. The top wall of the connecting groove is provided with assembly threaded holes corresponding to the positions of the assembly through holes of the mounting base. The mounting base and the housing are detachably connected by assembly bolts. The threaded portion of the assembly bolt passes through the assembly through hole of the mounting base and is screwed into the assembly threaded hole of the housing.

[0017] Furthermore, the connecting groove extends toward the output shaft, and the length direction of the connecting groove is its extending direction. The length direction of the mounting base is the same as the length direction of the connecting groove. The mounting base has an elongated mounting through hole, and the length direction of the mounting through hole is along the length direction of the mounting base. The first clamping bolt and nut assembly includes a first clamping bolt and a first clamping nut, and the shank of the first clamping bolt passes through the mounting through hole of the mounting base.

[0018] Furthermore, the power module is a wired power module, including a power cord, a power board, and a plug. The power board is disposed in the housing, and the two ends of the power cord are respectively connected to the plug and the power board. The power board is electrically connected to the control module.

[0019] Furthermore, the power module is a wireless power module, including a battery. The control module includes a power detection unit for detecting the battery's power level.

The outer shell of the battery has a first magnetic clasp, and the inner wall of the battery receiving slot has a second magnetic clasp corresponding to the first magnetic clasp. When the battery is fully inserted into the battery receiving slot, the battery's power transmission interface is inserted into the power socket, achieving electrical connection between the battery and the control module, while the first magnetic clasp aligns with the second magnetic clasp.

The second wireless communication module of the range hood is wirelessly connected to the first wireless communication module of the robotic arm, realizing the communication connection between the MCU module of the range hood and the control module of the robotic arm. When the methane detection module detects that the methane concentration reaches a set safety threshold, the MCU module of the range hood controls the exhaust fan to turn on, and at the same time sends a wireless signal to the robotic arm through the second wireless communication module of the range hood. After receiving the signal, the control module of the robotic arm controls the drive mechanism to drive the actuator to rotate. When the actuator rotates, it drives the handle of the valve installed on the gas inlet pipe to rotate, close the valve, and cut off the gas supply.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0041] Example 1

[0042] This embodiment provides a robotic arm, such as Figure 4 and Figure 5 As shown, the device includes a housing 1, a drive mechanism, and an actuator 2. The drive mechanism is housed within the housing 1 and includes a drive motor. The output shaft of the drive mechanism passes through the bottom wall of the housing 1, and the actuator 2 is mounted on the output shaft. A threaded rod is provided at the lower end of the output shaft, and a first fixing bolt 6 is installed on the threaded rod. The actuator 2 includes an actuator plate 201. One end of the actuator plate 201 has a connecting limiting hole, through which the actuator plate 201 is fitted onto the output shaft and fixed to it by the first fixing bolt 6. The other end of the actuator plate 201 has two sets of mounting holes, each set including multiple mounting holes 202 arranged sequentially along the length of the actuator plate 201. The two sets of mounting holes 202 are arranged along the width of the actuator plate 201. Limiting posts 203 are installed in the mounting holes 202. The limiting posts 203 have two installation methods, one being as follows: Figure 5 The limiting post 203 shown is installed in the mounting hole 202 by the second fixing bolt 7; another method is to directly thread the limiting post 203 into the mounting hole 202, in which case the mounting hole 202 is a threaded hole structure, and the upper end of the limiting post 203 is provided with a stud structure.

[0043] With the above configuration, the drive motor can drive the actuator 2 to rotate in a circular motion, allowing the actuator 2 to switch between a first position and a second position, with the first position being the initial position. In use, the two limiting posts 203 mounted on the actuator plate 201 engage with the handle of the valve mounted on the gas inlet pipe. In the initial position, the valve on the gas inlet pipe is open. When the actuator 2 switches from the first position to the second position, the actuator plate 201 rotates, and the two limiting posts 203 on the actuator plate 201 cause the handle of the valve mounted on the gas inlet pipe to rotate, closing the valve. When the actuator 2 switches from the second position to the first position, the two limiting posts 203 on the actuator plate 201 cause the handle of the valve mounted on the gas inlet pipe to rotate in the opposite direction, opening the valve, and the actuator 2 returns to the initial position.

[0044] like Figure 4 , Figure 6 and Figure 7 As shown, a mounting assembly is detachably connected to the lower end of the housing 1, and the housing 1 is connected to the gas pipe through the mounting assembly. The mounting assembly includes a mounting base 11 and two symmetrically arranged clamping plates 8. The clamping plates 8 include an upper straight plate portion 801, an arc-shaped plate portion 802, and a lower straight plate portion 803. The upper straight plate portion 801 and the lower straight plate portion 803 are respectively provided with an upper clamping connection hole 804 and a lower clamping connection hole 805. The upper straight plate portions 801 of the two clamping plates 8 are mounted on the mounting base 11 through a first clamping bolt and nut assembly 9. The arc-shaped plate portions 802 of the two clamping plates 8 are clamped on the gas pipe. The lower straight plate portions 803 of the two clamping plates 8 are connected through a second clamping bolt and nut assembly 10.

[0045] like Figure 4 and Figure 6 As shown, the bottom wall of the housing 1 is provided with a connecting groove that matches the upper end of the mounting base 11, and the upper end of the mounting base 11 is inserted into the connecting groove. Both ends of the mounting base 11 are provided with assembly through holes penetrating the mounting base 11 vertically. The top wall of the connecting groove is provided with assembly threaded holes corresponding to the positions of the assembly through holes of the mounting base 11. The mounting base 11 and the housing 1 are detachably connected by assembly bolts 12, the threaded portion of which passes through the assembly through hole of the mounting base 11 and is screwed into the assembly threaded hole of the housing 1. This arrangement allows the robotic arm to be installed by first installing the mounting components on the gas pipe, then installing the housing 1 on the mounting components, and finally installing the actuator 2. The most common installation location for robotic arms is near the gas meter, and in newly renovated rooms, they are usually installed inside cabinets where the installation space is very small. This invention separates and sequentially connects the various components of the robotic arm, making it very suitable for installation in small spaces.

[0046] like Figure 5 As shown, the actuator plate 201 is provided with two sets of mounting holes 202. Each set of mounting holes 202 includes multiple mounting holes 202 arranged sequentially along the length direction of the actuator plate 201, so that the position of the limiting post 203 can be installed on the mounting holes 202 at different positions as needed. Figure 4 and Figure 6 As shown, the connecting groove extends towards the output shaft of the drive mechanism, and its length direction is its extension direction. The length direction of the mounting base 11 is the same as the length direction of the connecting groove. The mounting base 11 has an elongated mounting through hole, and the length direction of the mounting through hole is along the length direction of the mounting base 11. The first clamping bolt and nut assembly 9 includes a first clamping bolt and a first clamping nut, and the shank of the first clamping bolt passes through the mounting through hole of the mounting base 11. With this configuration, the installation position of the clamping plate 8 can be adjusted along the length direction of the mounting base 11, thereby adjusting the installation positions of the housing 1, the actuator plate 201, and the limiting post 203. This design allows the robotic arm provided by this utility model to flexibly cope with complex pipeline conditions. Regardless of the length of the valve handle on the gas inlet pipe, it can ensure that the limiting post 203 is accurately engaged on both sides of the handle, ensuring a reliable limiting connection. This further improves the applicability of this utility model for installation in small spaces and is suitable for current decoration scenarios.

[0047] like Figure 11 As shown, the robotic arm also includes a power module, a control module, and a first wireless communication module. The drive motor of the drive mechanism, the power module, and the first wireless communication module are all electrically connected to the control module. Both the control module and the first wireless communication module are housed within the housing 1. The power module supplies power to the control module, the drive motor, and the first wireless communication module. The control module includes a circuit board and an MCU chip mounted on the circuit board. The first wireless communication module uses any one of a WiFi communication module, a Bluetooth communication module, or a 2.4G communication module. The control module wirelessly connects to devices with wireless communication and methane detection functions (such as range hoods, gas stoves, and gas water heaters) via the first wireless communication module.

[0048] like Figure 1 and Figure 2 As shown, the power module is a wired power module, including a power cord 3, a power board, and a plug 4. The power board is housed in the casing 1. The two ends of the power cord 3 are connected to the plug 4 and the power board, respectively. The power board is electrically connected to the control module. A robotic arm with a wired power module is a wired robotic arm, powered by a socket connected to the plug 4. The installation location is required, such as inside a cabinet where there is a socket.

[0049] like Figure 3 , Figure 4 , Figure 8 and Figure 9As shown, the power module is a wireless power module, which includes a battery 5. The housing 1 has a battery housing slot adapted to the shape of the battery 5. A power transmission interface 501 is located at the inner end of the battery 5. A power socket adapted to the power transmission interface 501 is located on the inner wall of the battery housing slot. The power socket is electrically connected to the control module. The power transmission interface 501 connects to the power socket, allowing the battery 5 to supply power to the control module, drive motor, and first wireless communication module. A first magnetic clasp 502 is located on the outer shell of the battery 5, and a second magnetic clasp corresponding to the first magnetic clasp 502 is located on the inner wall of the battery housing slot. When the battery 5 is fully inserted into the battery housing slot, the power transmission interface 501 of the battery 5 is inserted into the power socket, achieving electrical connection between the battery 5 and the control module. Simultaneously, the first magnetic clasp 502 aligns with the second magnetic clasp, thus ensuring that the battery 5 is securely installed in the battery housing slot and guaranteeing a stable power supply to the battery 5. The battery 5 has a handle 503 and a charging port 504 on its outer end. The handle 503 facilitates the removal of the battery 5, and the charging port 504 is used to connect a charging cable to power the battery 5. The control module has a power detection unit to detect the power level of the battery 5. An alarm electrically connected to the control module can be installed on the housing 1. When the battery 5 is detected to be low on power, the alarm will sound, reminding the user to charge the battery 5 or replace it with a spare battery 5. The control module can also be connected to a mobile APP via a first wireless communication module. When the battery 5 is detected to be low on power, the control module will send a low power reminder to the mobile APP, reminding the user to charge the battery 5 or replace it with a spare battery 5.

[0050] The robotic arm with a wireless power module is a wireless power robotic arm. It is powered by a socket connected to plug 4, and does not require a socket at the installation location. It is very suitable for scenarios where the robotic arm was not designed and installed in the early stage and needs to be installed later. Of course, it is also suitable for installation in small spaces.

[0051] In summary, the robotic arm provided by this utility model can wirelessly connect with equipment that has wireless communication and methane detection functions. No wiring is required to install the robotic arm, making its installation and use very convenient and well meeting users' dual needs for gas safety and home aesthetics.

[0052] Example 2

[0053] This embodiment provides a gas safety linkage component, including a range hood and the robotic arm provided in Embodiment 1. For example... Figure 10As shown, the range hood has a housing 13, on which a narrow, elongated air intake 14 and a smoke exhaust vent are provided. A smoke exhaust channel is formed between the narrow, elongated air intake 14 and the smoke exhaust vent, and a smoke exhaust fan is installed in the smoke exhaust channel. The housing 13 contains an MCU module, a second wireless communication module, and a methane detection mounting cavity. A methane detection module is installed in the methane detection mounting cavity, and the methane detection module can use an electrochemical detection module, a combustible gas detector, etc. A cover plate 15 is provided at the upper end of the methane detection mounting cavity, and an air inlet 16 is provided on the cover plate 15, through which outside air enters the methane detection mounting cavity.

[0054] like Figure 12 As shown, the exhaust fan, the second wireless communication module, and the methane detection module are all electrically connected to the MCU module. The second wireless communication module of the exhaust fan is wirelessly connected to the first wireless communication module of the robot, realizing the communication connection between the MCU module of the exhaust fan and the control module of the robot. When the methane detection module detects that the methane concentration reaches the set safety threshold, the MCU module of the exhaust fan controls the exhaust fan to turn on, expelling the leaked gas in the environment where the exhaust fan is located to the outside. At the same time, the second wireless communication module of the exhaust fan sends a wireless signal to the robot. After receiving the signal, the control module of the robot controls the drive mechanism to rotate the actuator 2. When the actuator 2 rotates, it rotates the handle of the valve installed on the gas inlet pipe, closing the valve and cutting off the gas supply.

[0055] like Figure 13 and Figure 14 As shown, the gas safety linkage component also includes an intelligent controller. The intelligent controller has a third wireless communication module, a display module, and an APP module. The intelligent controller communicates with the range hood and robotic arm via its third wireless communication module, enabling the APP module to be bound to the range hood and robotic arm. The intelligent controller can control the operation of the range hood and robotic arm through its APP module. The first wireless communication module of the robotic arm and the second wireless communication module of the range hood can both use any one of WiFi, Bluetooth, or 2.4G communication modules, and both modules must be of the same type. The third wireless communication module of the intelligent controller includes a near-ground wireless communication module and a long-range wireless communication module. The near-ground wireless communication module uses any one of WiFi, Bluetooth, or 2.4G communication modules and is used to communicate with the range hood and robotic arm. The long-range wireless communication module uses either a 4G or 5G communication module and is used for remote monitoring and control, data uploading, emergency alarms and notifications, software updates, and function upgrades.

[0056] In some exemplary embodiments, the APP module of the intelligent controller includes a range hood control submodule. This submodule includes a range hood control unit, a range hood operating parameter setting unit, and a range hood operating status unit. The range hood control unit can control the start / stop and operating speed of the range hood. The range hood operating parameter setting unit can set the start / stop conditions, shutdown delay duration, and start speed of the range hood. The range hood operating status unit has a range hood operating status page where users can view various operating parameters, including but not limited to operating speed, operating power, smoke concentration, and environmental quality parameters. Thus, the intelligent controller enables the setting of range hood operating parameters, real-time status monitoring, and remote control, greatly improving the convenience and autonomy of user operation of the range hood.

[0057] In addition, the APP module also includes a robot control submodule, which includes a robot control unit, a robot operating parameter setting unit, and a robot operating status unit. The robot's drive motor uses a stepper motor. The robot control unit can control the robot's start and stop. The robot operating parameter setting unit can set the angle of rotation of the robot's drive motor when the robot switches between the first and second position states. The width of the valve handle installed on the gas inlet pipe is uncertain, and the robot's installation position may not be very precise. There is a certain gap between the valve handle and the limit post 203. Therefore, when the robot switches between the first and second position states, the angle of rotation of the robot's drive motor does not control the valve handle to rotate 90 degrees. It needs to be debugged and set by the intelligent controller after the robot is installed to ensure that the robot can accurately control the valve's opening and closing state. The robot operating status unit has a robot operating status page, on which the position status of the robot's actuator 2 can be viewed, such as whether actuator 2 is in the first or second position state, and thus the valve's opening and closing state can be determined.

[0058] The gas safety linkage component provided in this embodiment constructs a comprehensive and intelligent gas safety protection system, which has many significant beneficial effects.

[0059] From a safety perspective, the coordinated operation of the range hood equipped with a methane detection module and the robotic arm forms a robust gas leak response mechanism. Once an abnormal methane concentration is detected, the range hood quickly activates its exhaust fan to promptly reduce the indoor gas concentration, while the robotic arm precisely shuts off the gas valve, effectively preventing continuous gas leakage and significantly reducing the likelihood of gas explosions, poisoning, and other safety accidents, thus building a strong safety barrier for users' homes.

[0060] In terms of kitchen equipment installation, since the range hood has a methane detection module that can detect gas leaks, there is no need to install a gas alarm, saving equipment costs and space.

[0061] In terms of ease of use, the smart controller and its app module provide users with powerful control capabilities. The smart controller allows for easy remote control and parameter settings of the range hood and robotic arm, enabling users to flexibly adjust equipment operation whether at home or away. For example, users can turn on the range hood in advance on their way home or remotely check the status of the robotic arm valves, greatly enhancing the user experience.

[0062] From an equipment management and maintenance perspective, the intelligent controller's remote wireless communication module enables data uploading, remote monitoring, and software upgrades. On one hand, manufacturers and users can monitor equipment operating data in real time, anticipate potential failures, and perform timely maintenance. On the other hand, remote software updates allow for continuous optimization of equipment functionality, keeping pace with technological advancements and ensuring consistently efficient and stable operation.

[0063] In terms of product sales, with the improvement of people's living standards and the increasing emphasis on home safety, the market demand for gas safety-related products continues to rise. This gas safety linkage component directly addresses users' pain points regarding gas leak protection, providing a comprehensive solution for home gas safety. It precisely meets this huge, rigid market demand, thereby attracting the attention and purchase of many consumers who value home safety.

[0064] In summary, the gas safety linkage component provided in this embodiment includes a range hood with a methane detection module and a robotic arm. The range hood and robotic arm are communicatively connected, eliminating the need for a separate gas alarm in the kitchen, thus saving equipment costs and space. When a gas leak is detected by the range hood, it can not only control the robotic arm to quickly cut off the gas supply, but also automatically start the range hood's exhaust fan to accelerate the discharge of leaked gas and reduce the indoor gas concentration.

[0065] Example 3

[0066] This embodiment provides a gas safety linkage component, including a gas appliance and a robotic arm as described in Embodiment 1. The gas appliance and the robotic arm are communicatively connected. The gas appliance includes any one or both of a gas stove and a gas water heater, and the gas appliance has a gas leak detection module.

[0067] like Figure 15As shown, the gas appliance is a gas stove, which includes a first main control module, a fourth wireless communication module, and a first gas leak detection module. Both the fourth wireless communication module and the first gas leak detection module are electrically connected to the first main control module. The first main control module includes a motherboard and a microprocessor, power management circuit, input / output interface circuit, and storage circuit on the motherboard. The fourth wireless communication module uses any one of a WiFi communication module, Bluetooth communication module, or 2.4G communication module, and should be compatible with the type of the first wireless communication module of the robotic arm. The first gas leak detection module can use an electrochemical detection module, a combustible gas detector, etc. The fourth wireless communication module of the gas stove is wirelessly connected to the first wireless communication module of the robotic arm, realizing the communication connection between the first main control module of the gas stove and the control module of the robotic arm.

[0068] When the gas stove's first leak detection module detects a gas leak, it shuts off the gas stove. Some gas stoves have solenoid valves installed on their pipes; the gas stove's first main control module can shut off the gas stove by controlling the solenoid valve to close. The gas stove transmits a wireless signal to the robotic arm, and the robotic arm's drive mechanism drives actuator 2 to switch from a first position state to a second position state. At this time, the limiting structure of actuator 2 causes the handle of the valve installed on the gas inlet pipe to rotate, closing the valve and cutting off the gas supply.

[0069] like Figure 15 As shown, the gas stove also includes a first temperature detection module electrically connected to the first main control module. The first temperature detection module includes a temperature sensor, which can be a thermocouple temperature sensor or an infrared temperature sensor, and can be installed in the burner head or on the bottom shell of the gas stove. The first main control module of the gas stove has a time control unit, which includes electronic circuitry and a clock chip. The first main control module is set with a first temperature threshold and a time threshold. The first temperature detection module transmits the detected temperature data to the first main control module. When the temperature value detected by the first temperature detection module reaches the first temperature threshold, or when the continuous ignition time of the gas hood reaches the time threshold, the first main control module transmits a signal to the robotic arm. The drive mechanism of the robotic arm drives the actuator 2 to switch from a first position state to a second position state. In this way, the gas supply can be cut off in time when dry burning occurs in the gas stove, effectively avoiding problems such as damage to cookware or even fire caused by dry burning.

[0070] like Figure 16As shown, the gas appliance is a gas water heater. The gas water heater includes a second main control module, a fifth wireless communication module, and a second gas leak detection module. Both the fifth wireless communication module and the second gas leak detection module are electrically connected to the second main control module. The second main control module includes a motherboard and a microprocessor, power management circuit, input / output interface circuit, and storage circuit on the motherboard. The fifth wireless communication module uses any one of a WiFi communication module, Bluetooth communication module, or 2.4G communication module, and should be compatible with the type of the first wireless communication module of the robotic arm. The second gas leak detection module can use an electrochemical detection module, a combustible gas detector, etc. The fifth wireless communication module of the gas water heater is wirelessly connected to the first wireless communication module, realizing the communication connection between the second main control module of the gas water heater and the control module of the robotic arm.

[0071] When the second gas leak detection module of the gas water heater detects a gas leak, it shuts down the gas water heater. A solenoid valve is installed on the gas pipeline of the gas water heater, and the second main control module of the gas water heater can control this solenoid valve to close, thereby shutting down the gas water heater. Simultaneously, the gas water heater transmits a wireless signal to the robotic arm, causing the robotic arm's drive mechanism to switch actuator 2 from a first position to a second position. At this time, the limiting structure of actuator 2 causes the handle of the valve installed on the gas inlet pipe to rotate, closing the valve and cutting off the gas supply.

[0072] like Figure 16 As shown, the gas water heater also includes a second temperature detection module electrically connected to the second main control module. This second temperature detection module uses a thermocouple temperature sensor and is located inside the inner tank of the water heater to detect its temperature. When the gas water heater malfunctions, such as a water flow detection failure, control system malfunction, or temperature system malfunction, dry burning may occur. In this case, the temperature of the inner tank will rise sharply, quickly exceeding the normal operating temperature range and potentially reaching the tolerance limit of the inner tank material. This can lead to deformation, damage, or even serious safety hazards such as explosion. The second main control module has a second temperature threshold. The second temperature detection module transmits the detected temperature data to the second main control module. When the detected temperature reaches the second temperature threshold, the second main control module sends a signal to the robotic arm, causing the robotic arm's drive mechanism to switch the actuator 2 from the first position state to the second position state. This allows for timely cutting off of the gas supply when dry burning occurs, effectively preventing further escalation of the malfunction.

[0073] The gas safety linkage component provided in this embodiment has many significant beneficial effects.

[0074] From a safety perspective, the collaborative operation of gas appliances equipped with leak detection modules and robotic arms forms a robust gas leak response mechanism. Once an abnormal methane concentration is detected, the gas appliance immediately shuts off, while the robotic arm precisely closes the gas valve, effectively preventing continuous gas leakage and significantly reducing the likelihood of gas explosions and other safety accidents, thus building a strong safety barrier for users' homes.

[0075] In terms of kitchen equipment installation, since gas appliances have methane detection modules that can detect gas leaks, there is no need to install gas alarms, saving equipment costs and space.

[0076] In terms of product sales, with the improvement of people's living standards and the increasing emphasis on home safety, the market demand for gas safety-related products continues to rise. This gas safety linkage component directly addresses users' pain points regarding gas leak protection, providing a comprehensive solution for home gas safety. It precisely meets this huge, rigid market demand, thereby attracting the attention and purchase of many consumers who value home safety.

[0077] In summary, the gas safety linkage component provided in this embodiment includes a gas appliance with gas leak detection function and a robotic arm. The gas appliance and the robotic arm are communicatively connected, eliminating the need for a separate gas alarm in the kitchen, thus saving equipment costs and space. When a gas leak is detected by the gas appliance, it can not only control the robotic arm to quickly cut off the gas supply, but also immediately and automatically shut off the gas appliance, effectively preventing explosion accidents.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
