Description

Technical Field

[0001] This invention belongs to the field of intelligent door and window technology, specifically a linked gas detection alarm door and window. Background Technology

[0002] In modern building environments, gas, as one of the main energy sources, has been used in all aspects of home life. However, safety accidents caused by gas leaks, such as fires, explosions, and poisoning, are common and pose a serious threat to life and property. Therefore, installing gas alarms and equipping them with effective emergency response facilities has become a key measure to ensure indoor environmental safety.

[0003] Currently, most mainstream gas safety solutions on the market rely on independent gas alarms. When these devices detect a leak, they can usually only issue an audible and visual alarm. This "only alarm, no action" mode has obvious defects. If the user fails to notice the alarm in time, is unable to move around, or is not on site, the system is difficult to intervene effectively, which may lead to the situation continuing to worsen and missing the best time to control it.

[0004] To improve automation, some intelligent ventilation systems have introduced electric push rods or motor drives to achieve automatic window opening. However, these systems generally suffer from problems such as rigid connection of the transmission mechanism, concentrated force during movement, and easy jamming, which affect the smoothness of opening and closing and the lifespan of the equipment. Furthermore, in daily use scenarios, if users need to manually open the windows for ventilation, they may accidentally trigger the gas cut-off protection, affecting normal cooking and causing inconvenience. It is difficult to strike a balance between safety and ease of use. In view of this, we propose a linkage-type gas detection alarm door and window. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies and proposes a linkage-type gas detection alarm door and window; it achieves automatic window opening and gas shut-off linkage protection in the event of a gas leak, while avoiding transmission jamming and allowing manual window opening during daily use without triggering gas shut-off.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: A linked gas detection alarm door and window includes a gas detector, a mounting frame, and a window hinged to the mounting frame. The mounting frame has an opening and closing assembly, and a control assembly is located below the opening and closing assembly. The opening and closing assembly includes a linkage mechanism and an electric telescopic rod. The linkage mechanism is connected to the window, and the electric telescopic rod is used to disconnect / connect the opening and closing assembly and the control assembly. The control assembly includes a rotary valve for controlling the gas flow rate. When the gas detector detects that the gas concentration exceeds a threshold, it issues an alarm and simultaneously drives the opening and closing assembly to open the window, synchronously triggering the rotary valve in the control assembly to close.

[0007] Furthermore, the opening and closing assembly also includes electric slide rails fixedly installed at the upper and lower ends inside the mounting frame. Electric sliders are slidably connected inside the electric slide rails, and a linkage mechanism connects the window and the electric sliders.

[0008] Furthermore, the linkage mechanism includes a first rotating plate and a second rotating plate; the electric slider is rotatably connected to the first rotating plate, the middle of the first rotating plate is rotatably connected to the second rotating plate, and the end of the first rotating plate away from the electric slider is hinged to the window; the second rotating plate is rotatably connected to a fixing block, which is fixedly installed inside one end of the electric slide rail.

[0009] Furthermore, the control assembly also includes a power rod fixedly connected to the bottom of the electric slider below. An eccentric wheel is rotatably connected to the end of the power rod away from the mounting frame. The bottom of the eccentric wheel is connected to the top of the rotary valve by bolts. A gas pipe is provided below the eccentric wheel, and the rotary valve is fixedly installed on the gas pipe.

[0010] Furthermore, a fixing plate is fixedly connected to the fixed end of the electric telescopic pole, and the fixing plate is connected to the inner wall of the mounting frame. The telescopic end of the electric telescopic pole is rotatably connected to the fixing block and the second rotating plate.

[0011] Furthermore, electric valves are fixedly installed on the gas pipeline; mounting brackets are also fixedly installed at both ends of the gas pipeline, and the gas pipeline is connected to the wall through the mounting brackets.

[0012] Furthermore, a groove for moving the power lever is provided at the bottom of the mounting frame.

[0013] Furthermore, the mounting frame is also equipped with an exhaust assembly, and the gas detector is installed inside the exhaust assembly.

[0014] Furthermore, the exhaust assembly also includes a mounting cavity and an exhaust fan; the output end of the mounting cavity has an exhaust port that penetrates the mounting frame, and the exhaust fan is closer to the exhaust port than the gas detector.

[0015] Furthermore, a sealing frame is fixedly installed on the side of the mounting frame near the exhaust fan; the sealing frame is used to wrap the exhaust assembly.

[0016] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention uses the cooperation of an electric slide rail and an electric slider to drive a linkage mechanism consisting of a first rotating plate and a second rotating plate, thereby achieving smooth opening and closing of the window. When the electric slider moves along the slide rail, it drives the first rotating plate to rotate around the connection point between the first rotating plate and the slider, which in turn pushes the second rotating plate to rotate around the fixed block as a fulcrum, thereby pulling the window to rotate around the hinge to open or close. The entire transmission process is smooth and stable, avoiding the problems of jamming or uneven force caused by direct pushing and pulling.

[0017] 2. When the gas detector detects that the concentration of gas in the environment exceeds the safety threshold, it immediately triggers the audible and visual alarm function, emitting a high-decibel buzzer and flashing red light to issue an emergency warning to the user. At the same time as the alarm is issued, the system automatically activates the emergency linkage mechanism. The electric telescopic rod extends and embeds into the second rotating plate to achieve the locking linkage between the opening and closing components and the window. Then, the electric slider starts, and the window is automatically pushed open through the first and second rotating plates. At the same time, this action is transmitted to the eccentric wheel through the power pull rod, which drives it to rotate and then drives the rotary valve bolted to it to close, cutting off the gas flow in the gas pipeline. This achieves the simultaneous execution of window ventilation and gas cut-off protection, effectively preventing safety accidents caused by continuous gas leakage.

[0018] 3. In daily use, the electric telescopic rod can be actively controlled to retract, causing it to detach from the second rotating plate and deactivating the automatic linkage mechanism. At this time, the user can manually open the window for ventilation. Since there is no mechanical connection between the power rod, the eccentric wheel, and the rotary valve, the gas valve will not be triggered to close, ensuring the normal use of the gas equipment and balancing safety and ease of use.

[0019] 4. The exhaust assembly of this invention is integrated into the mounting cavity on the back of the mounting frame. Both the exhaust fan and the gas detector are placed inside the sealed frame. The exhaust fan is positioned close to the exhaust port, which can efficiently guide the airflow to the outside. When the window is open, the exhaust fan enters high-power mode and operates in synergy with natural air intake, significantly improving the exhaust speed of indoor polluted air, especially gas. When operating at low power, the exhaust fan maintains a gentle breeze circulation, and the gas detector continuously monitors the ambient concentration. At the same time, the pulsed airflow generated by the exhaust fan removes oil stains adhering to the surface of the gas detector, preventing oil fume deposition from causing a decrease in sensor sensitivity or false alarms, and ensuring long-term accurate and reliable monitoring data.

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solutions of this invention are described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0023] See Figures 1 to 8 This embodiment proposes a linkage gas detection alarm door and window, including a mounting frame 100 and a window 101 hinged to the mounting frame 100. The mounting frame 100 is provided with an opening and closing component 200 and an exhaust component 400, and a control component 300 is provided below the opening and closing component 200. The opening and closing assembly 200 includes a linkage mechanism and an electric telescopic rod 206. The linkage mechanism is connected to the window 101. The electric telescopic rod 206 is used to disconnect / connect the opening and closing assembly 200 and the control assembly 300. The control assembly 300 includes a rotary valve 303 for controlling the gas flow rate. The exhaust assembly 400 includes an exhaust fan 402 and a gas detector 403. When the opening / closing component 200 drives the window 101 to open, it simultaneously triggers the rotary valve 303 in the control component 300 to perform a closing action. When the exhaust assembly 400 and window 101 are opened simultaneously, the exhaust assembly 400 enters a high-power operation mode to enhance the efficiency of indoor gas exhaust; when operating at low power, the exhaust assembly 400 enters an auxiliary monitoring mode to work with the gas detector 403 to monitor the gas concentration in real time and simultaneously clean the oil stains on the sensor surface.

[0024] Therefore, based on the above features, the improvements of the present invention will be described in detail: Considering that most products on the market are currently only at the basic stage of "single-point detection" and "audible and visual alarm", when the alarm is triggered, the system itself lacks an effective active handling mechanism and still relies on personnel to manually open windows for ventilation, close gas valves, etc. after receiving the alarm. This process has problems such as response delay, low handling efficiency, and complete failure when the user is not present. Furthermore, when the indoor gas concentration is too high, relying solely on natural convection ventilation formed by opening windows results in a slow gas diffusion rate, making it difficult to effectively reduce the dangerous gas concentration in a short period of time, thus posing a safety hazard. At the same time, during long-term use, the surface of the gas detector 403 is prone to being covered with oil stains such as kitchen grease, which can lead to a decrease in detection sensitivity or even failure, affecting the accurate monitoring and timely warning of gas leaks. Therefore, when an abnormality occurs in the indoor environment, such as when the gas detector 403 detects that the concentration of gas in the environment exceeds the safety threshold, the audible and visual alarm function is immediately triggered, emitting a high-decibel buzzer and flashing red light to issue an emergency warning to the user. At the same time as the alarm is issued, the system automatically activates the emergency linkage mechanism. After the emergency linkage mechanism is activated, the control center built into the window 101 activates the electric telescopic rod 206 in the opening and closing assembly 200, which is inserted into the linkage mechanism. The opening and closing assembly 200 simultaneously pushes the window 101 to rotate around the hinge to achieve automatic opening. At the same time as the window 101 opens, the rotary valve 303 in the control assembly 300 is triggered to close immediately, cutting off the gas supply and fundamentally preventing continuous gas leakage during ventilation, thus avoiding the potential explosion risk caused by the accelerated gas diffusion due to air convection. This linkage mechanism ensures that ventilation and gas cut-off are carried out simultaneously, improving the reliability and safety of emergency response. Simultaneously, the exhaust assembly 400 activates when window 101 is opened and enters a high-power operation mode, actively enhancing the forced exhaust of indoor air. This, combined with the open window 101, creates an efficient airflow, significantly increasing the exhaust speed of the gas and shortening the residence time of hazardous gases, thus compensating for the low efficiency of relying solely on natural convection for smoke extraction. In normal low-power operation, the exhaust assembly 400 switches to auxiliary monitoring mode, with its built-in gas detector 403 continuously monitoring the gas concentration in the air, achieving dynamic environmental perception. Since oil fumes in the kitchen environment easily adhere to the sensor surface of the gas detector 403, causing detection failure, the system periodically activates the exhaust assembly 400 to remove oil deposits from the sensor using airflow, maintaining the sensitivity and accuracy of the detection element and ensuring long-term stable and reliable detection functionality.

[0025] During normal daily use, to ensure that ventilation needs and the normal operation of gas facilities do not interfere with each other, the electric telescopic rod 206 can be periodically activated to retract, causing its end to smoothly disengage from the second rotating plate 204. This temporarily releases the mechanical connection between the opening / closing component 200 and the window 101, and disconnects the linkage between the opening / closing component 200 and the control component 300. At this time, the window 101 is no longer constrained, and the operator can manually push it open for natural ventilation, meeting daily needs such as air exchange and room temperature regulation. Since the linkage mechanism has been disconnected, opening the window 101 will not trigger the closing of the rotary valve 303 in the control component 300, and the gas supply remains uninterrupted. Users can continue to use gas stoves and other equipment normally, avoiding the inconvenience caused by accidental gas outages due to ventilation. This system balances the flexibility of emergency safety with daily use, enabling automatic window opening and gas outage interlocking in emergencies while allowing users to operate it independently in a safe environment, thus improving the system's practicality and user-friendliness.

[0026] Based on the above, the specific structure will be disclosed in detail: To achieve the opening and closing of window 101, the detailed opening and closing component 200 is disclosed, as follows: Figure 2 - Figure 4 As shown, the opening and closing assembly 200 also includes an electric slide rail 201 fixedly installed at both the upper and lower ends inside the mounting frame 100. An electric slider 202 is slidably connected inside the electric slide rail 201, and the electric slider 202 is adapted to the size of the electric slide rail 201. The linkage mechanism includes a first rotating plate 203 and a second rotating plate 204. The electric slider 202 is rotatably connected to the first rotating plate 203, and the second rotating plate 204 is rotatably connected to the middle of the first rotating plate 203. The end of the first rotating plate 203 away from the electric slider 202 is hinged to the window 101. The cooperation of the first rotating plate 203 and the second rotating plate 204 is used to open and close the window 101. The second rotating plate 204 is rotatably connected to a fixing block 205, and the fixing block 205 is fixedly installed inside one end of the electric slide rail 201.

[0027] Therefore, by fixing the electric slide rail 201 to the upper and lower ends inside the mounting frame 100, the built-in electric slider 202 can slide smoothly within the electric slide rail 201. The electric slider 202 is connected to one end of the first rotating plate 203 via a hinge shaft, and the other end of the first rotating plate 203 is hinged to the second rotating plate 204. The end of the second rotating plate 204 is rotatably connected to the fixed block 205, forming a swing structure with the fixed block 205 as the fulcrum. When the system receives the window opening command, the electric sliders 202 on both the upper and lower sides move synchronously, pushing the first rotating plate 203 to rotate. Since one end of the second rotating plate 204 rotates to the fixed block 205... On the fixed block 205, the other end is hinged to the first rotating plate 203. Therefore, the movement of the first rotating plate 203 is converted into the swing of the second rotating plate 204 around the fixed block 205, thereby pushing the window 101 to open smoothly around its hinge axis. When closing, the electric slider 202 moves in the opposite direction, pulling the first rotating plate 203 back to its original position, and driving the second rotating plate 204 to swing in the opposite direction, so that the window 101 closes smoothly. This linkage mechanism converts the linear motion of the electric slider 202 into the rotational motion of the window 101. The force is evenly distributed during the transmission process, avoiding jamming or local stress concentration caused by direct pushing and pulling, and ensuring smooth and reliable opening and closing action.

[0028] Specifically, a fixing plate is fixedly connected to the fixed end of the electric telescopic rod 206. The fixing plate is connected to the inner wall of the mounting frame 100. The telescopic end of the electric telescopic rod 206 is rotatably connected to the fixing block 205 and the second rotating plate 204. The connection between the telescopic end of the electric telescopic rod 206 and the second rotating plate 204 and the fixing block 205 forms a rotating pair. In the normal linkage state of the system, the electric telescopic rod 206 is in the extended state, and its telescopic end is embedded in the second rotating plate 204, realizing the mechanical connection between the opening and closing component 200 and the window 101, ensuring that the movement of the electric slider 202 can be effectively transmitted to the window 101 to complete the automatic opening and closing.

[0029] Furthermore, to achieve control of gas flow, the control component 300 is disclosed in detail, specifically as follows: Figure 5 - Figure 7 As shown, the control assembly 300 also includes a power rod 301 fixedly connected to the bottom of the electric slider 202 below. An eccentric wheel 302 is rotatably connected to the end of the power rod 301 away from the mounting frame 100. The bottom of the eccentric wheel 302 is connected to the top of the rotary valve 303 by bolts. A gas pipe 304 is provided below the eccentric wheel 302. The rotary valve 303 is fixedly installed on the gas pipe 304. Therefore, when the electric slider 202 moves within the electric slide rail 201 to drive the window 101 to open, the power pull rod 301 fixed at its bottom moves synchronously and moves together with the electric slider 202. The free end of the power pull rod 301 drives the eccentric wheel 302 connected to it to rotate around its own axis through the hinge joint. Since there is an eccentricity between the geometric center of the eccentric wheel 302 and the axis of rotation, it will generate reciprocating oscillation or rotational displacement during rotation. This movement is directly transmitted to the control end of the rotary valve 303 through the bolt at the top, causing the valve core inside the rotary valve 303 to rotate to the closed position, thereby cutting off the gas supply in the gas pipeline 304. This ensures the synchronous execution of opening the window 101 and cutting off the gas supply. It does not rely on complex electrical control signals or additional actuators, and has a rapid response and high reliability, fundamentally preventing safety accidents caused by continuous gas leakage during ventilation.

[0030] Specifically, an electric valve 305 is also fixedly installed on the gas pipeline 304. Therefore, the rotary valve 303 installed on the gas pipeline 304 below the eccentric wheel 302 serves as the main control valve that is linked to the opening and closing of the window 101, and is used for rapid gas shut-off in emergencies. At the same time, the pipeline is also equipped with an electric valve 305 as a backup or auxiliary control device, which can be opened and closed independently under the command of the control system to achieve remote control or multi-level safety protection, improve the redundancy and safety of the system, and can also control the gas flow when the rotary valve 303 fails.

[0031] Both ends of the gas pipeline 304 are fixedly installed with mounting bases, which connect the gas pipeline 304 to the wall. The bottom of the mounting frame 100 is provided with a sliding groove for the movement of the power rod 301. The sliding groove on the mounting frame 100 provides a movement channel for the lower end of the power rod 301. When the electric slider 202 moves back and forth, the power rod 301 can slide freely in the sliding groove to avoid interference with the mounting frame 100 and ensure smooth transmission. Wear-resistant bushings are provided at the edge of the sliding groove to reduce friction loss during long-term operation. A sealing frame is also fixedly installed on the side of the mounting frame 100 near the exhaust fan 402; the sealing frame is used to wrap the exhaust assembly 400, effectively isolate the external environment, prevent rainwater, dust or fumes from flowing back into the exhaust assembly 400 from the exhaust port, protect the exhaust fan 402 and gas detector 403 and other precision components, extend the service life of the equipment, and at the same time improve the sealing and aesthetics of the overall structure.

[0032] However, to improve the emission rate of coal gas and clean the oil stains on the testing equipment, detailed information on the exhaust assembly 400 is required, specifically as follows: Figure 7 and Figure 8As shown, the exhaust assembly 400 includes an installation cavity 401 fixedly installed at the upper and lower ends of the back of the installation frame 100. The output end of the installation cavity 401 has an exhaust port that penetrates the installation frame 100, forming an airflow channel. An exhaust fan 402 and a gas detector 403 are installed inside the installation cavity 401, with the exhaust fan 402 being closer to the exhaust port than the gas detector 403. When the exhaust fan 402 is started, its rotation generates negative pressure, forcibly drawing indoor air out of the exhaust port and forming an outward airflow. Since the exhaust fan 402 is at the front end, the airflow passes through the installation cavity 401 at high speed under its drive, forming a stable airflow path in the area where the gas detector 403 is located, ensuring that the surrounding air is continuously drawn to the vicinity of the sensor of the gas detector 403, thereby improving the response speed and detection accuracy of the gas concentration in the air. When window 101 is open and excessive gas levels are detected, exhaust fan 402 enters high-power operation mode, forming a synergistic ventilation effect with the open window 101. Indoor polluted air enters through window 101 and is then powerfully exhausted by exhaust fan 402, significantly improving the removal efficiency of harmful gases and shortening the residence time of dangerous concentrations. During normal low-power operation, the exhaust fan 402 maintains a low speed to achieve continuous air circulation and prevent local gas accumulation. At the same time, since oil fumes in the kitchen environment easily adhere to the sensor surface, the system periodically controls the exhaust fan 402 to briefly increase its speed to generate a pulsed airflow. When this airflow passes through the gas detector 403 probe, it can impact and carry away the attached oil particles, thereby achieving automatic cleaning of the sensor and avoiding decreased sensitivity or false alarms or missed alarms due to oil covering.

[0033] The working steps of this invention are as follows: When the gas detector 403 detects that the concentration of gas in the environment exceeds the safety threshold, it immediately triggers the audible and visual alarm function, emitting a high-decibel buzzer and a red flashing light to issue an emergency warning to the user. At the same time as the alarm is issued, the system automatically activates the emergency linkage mechanism. After the emergency linkage mechanism is activated, the control center built into the window 101 starts the electric telescopic rod 206 and extends it into the second rotating plate 204, so that its end is embedded in the second rotating plate 204, realizing the mechanical connection between the opening and closing component 200 and the window 101. At the same time, the electric sliders 202 in the electric slide rails 201 at the upper and lower ends move synchronously, driving the first rotating plate 203 to rotate around its connection point with the electric slider 202, thereby pushing the second rotating plate 204 to swing outward with the fixed block 205 as the fulcrum. The movement of the second rotating plate 204 is converted into a thrust on the window 101 through its rotational connection with the fixed block 205, so that the window 101 rotates smoothly around the hinge axis to open, forming a ventilation channel. As the electric slider 202 moves, the power rod 301 connected to its bottom moves in the same direction, driving the eccentric wheel 302 to rotate around its axis by rotating the connecting end. The eccentric structure of the eccentric wheel 302 converts the linear reciprocating motion into rotational motion. When the eccentric wheel 302 rotates through a certain angle, it rotates the valve 303 through the bolt at the top, causing its valve core to rotate to the closed position, cutting off the airflow in the gas pipeline 304, and realizing the synchronous execution of opening the window and cutting off the gas. At this time, the exhaust assembly 400 receives the system start signal, and the exhaust fan 402 in the installation cavity 401 switches to high-power operation mode. The exhaust fan 402 rotates at high speed to generate negative pressure, forcibly expelling the indoor air through the exhaust port, forming an internal and external airflow circulation with the open window 101, accelerating the dilution and exhaust of the gas.

[0034] In normal, non-emergency situations, users can retract the electric telescopic rod 206 back to its initial position via the control panel or manual operation commands. Its top end will completely retract from the second rotating plate 204, releasing the mechanical connection between the opening / closing assembly 200 and the window 101. At this time, the window 101 is no longer constrained by the electric slider 202 and the linkage mechanism, and users can directly push the window sash around the hinge to open it for natural ventilation. Since the electric telescopic rod 206 is in the retracted state, the electric slider 202 does not move, the power pull rod 301 remains stationary, the eccentric wheel 302 and the rotary valve 303 remain in their original positions, the gas pipeline 304 remains unobstructed, and the gas equipment can be used normally without accidentally triggering a gas outage due to manually opening the window.

[0035] During normal system operation, the exhaust component 400 can be set to low-power standby mode, and the exhaust fan 402 operates at low speed to maintain indoor air micro-circulation. At the same time, the gas detector 403 continuously monitors the gas concentration in the air. The system starts the self-cleaning program according to the preset cycle. The exhaust fan 402 briefly increases its speed and generates a pulse airflow to impact the sensor probe surface of the gas detector 403, blowing away the attached oil particles and preventing oil fume deposition from causing a decrease in detection sensitivity.
