Description

Technical Field

[0001] This invention belongs to the field of smart home technology, specifically a safety door and window for automatically alarming and opening in case of gas leaks. Background Technology

[0002] Existing safety doors and windows for automatic alarm and opening during gas leaks have several shortcomings: First, most devices cannot automatically open doors and windows when a gas leak occurs, still requiring manual operation. In cases where personnel are not present or are incapacitated by poisoning, the inability to open doors and windows for ventilation can lead to a continuous increase in gas concentration, increasing the risk. Second, there is a lack of effective automatic alarm mechanisms. Even if some devices are equipped with alarm functions, it is difficult to simultaneously alert people both inside and outside. People inside may not notice due to being asleep, and people outside are even less aware of the gas leak, delaying rescue and response. Summary of the Invention

[0003] This invention overcomes the shortcomings of existing technologies and proposes a safety door and window for automatic alarm and opening in case of gas leakage; this invention is achieved through the following technical solution:

[0004] A safety door and window for automatic alarm and opening in case of gas leak includes a window frame installed at one end of a room, with outward-opening windows symmetrically installed inside the window frame; a door frame installed at the end of the room away from the window frame, with a pneumatic door installed inside the door frame, and a gas alarm installed inside the room; a sash frame rotatably connected at the end of the room near the window frame, with fan blades installed inside the sash frame; and a window opening assembly installed inside the room. When a gas leak occurs, the window opening assembly opens the outward-opening windows and rotates the sash frame to a state parallel to the window frame, aligning the fan blades with the window frame, thereby reducing the gas concentration in the room by activating the fan blades.

[0005] Each of the two outward-opening windows has a storage slot at one end facing each other. A ribbon is installed inside each storage slot. One end of the ribbon is fixedly connected to the inner wall of the storage slot, while the other end of the ribbon is free. A limit component is installed inside the outward-opening window. When a gas leak occurs, the limit component releases the limit on the ribbon and pushes the ribbon out. The ribbon works with the fan blades to make the ribbon flutter outdoors, which is used to alert people outdoors that there is a gas leak inside the room.

[0006] A door opening assembly is installed on the side of the room near the door frame. In the event of a gas leak, the door opening assembly unlocks the pneumatic door and opens it, creating airflow between the door frame and the window frame. This, combined with the fan blades guiding the airflow, promotes the expulsion of gas. Inside the door frame, a sound-emitting component is installed. When the pneumatic door is fully opened, the sound-emitting component will emit a sound to alert people nearby or inside the room that a gas leak has occurred.

[0007] Furthermore, the window opening assembly includes a rotating rod, a driving cone wheel, a driven cone wheel, a push-window rod, and a connecting plate; the rotating rod is rotatably connected inside the window frame, and driving cone wheels are fixedly connected to both ends of the rotating rod; driven cone wheels are symmetrically rotatably connected to the top of the inner wall of the window frame, and the driving cone wheel meshes with the driven cone wheel; a push-window rod is fixedly connected to the bottom of each driven cone wheel, and the push-window rod is used to push the outward-opening window to rotate; a connecting plate is fixedly connected to the middle of the rotating rod, and the top of the connecting plate is fixedly connected to the sash frame.

[0008] Furthermore, a dual-axis motor is fixedly connected inside the room, with one output end of the dual-axis motor fixedly connected to a rotating rod; a rope winding roller is fixedly connected to the other output end of the dual-axis motor, and a rope is wound around the outer wall of the rope winding roller; a valve handle is installed on the top of the valve on the gas pipeline inside the room, and a guide roller is rotatably connected inside the room, with one end of the rope passing over the guide roller and fixed to the end of the valve handle.

[0009] Furthermore, the limiting component includes a first sliding groove, a pusher block, a first compression spring, a first slot, and a first locking plate; the interior of the outward-opening window has a first sliding groove, and a pusher block for pushing the ribbon out of the storage slot is slidably connected in the first sliding groove. One end of the pusher block is fixedly connected to a first compression spring, and the end of the first compression spring away from the pusher block is fixedly connected to the outward-opening window; the top of the pusher block has a first slot, and the interior of the outward-opening window is slidably connected to a first locking plate, which engages with the first slot.

[0010] Furthermore, a baffle is rotatably connected to the middle of one end of the storage slot, and the bottom end of the baffle is rotatably connected to the outward opening window. The baffle is used to prevent the ribbon from sliding out of the storage slot. The height of the side of the storage slot near the baffle is twice the height of the baffle. A second locking plate is slidably connected inside the outward opening window, and the second locking plate is engaged with the top of the baffle.

[0011] Furthermore, the limiting assembly also includes a second slide groove, a connecting slider, a second compression spring, an inclined groove, an inclined push block, and a third compression spring; the interior of the outward-opening window has a second slide groove, and the connecting slider is slidably connected inside the second slide groove. The two ends of the bottom of the connecting slider are respectively fixed to the top of the first and second plates; the top of the second slide groove is fixedly connected to the second compression spring, and the bottom of the second compression spring is fixed to the top of the connecting slider; the middle of the first plate has an inclined groove, and an inclined push block is slidably connected to one side of the outward-opening window. The inclined push block is inserted into the inclined groove, and the inclined push block contacts the inclined surface of the inclined groove; when the window push rod pushes the outward-opening window, the window push rod squeezes the inclined push block.

[0012] Furthermore, the door opening assembly includes a pivot, a turntable, a torsion spring, a locking block, a connecting rod, a first air cylinder, a first piston, and a push block; a pivot is rotatably connected to the interior of one end of the pneumatic door, with handles fixedly connected to both ends of the pivot, and a turntable fixedly connected to the outer wall of the pivot's middle section; torsion springs are symmetrically fixedly connected to the outer wall of the pivot, with the opposite ends of the two torsion springs fixedly connected to the pneumatic door; a locking block is slidably connected to one end of the pneumatic door, engaging with the door frame, and a connecting rod is symmetrically installed between the locking block and the turntable, with both ends of the connecting rod rotatably connected to the sides of the locking block and the turntable; a first air cylinder is fixedly connected to the interior of the door frame, and a first piston is slidably connected to the interior of the first air cylinder; a push block is slidably connected to the interior of the door frame, with one end of the push block fixed to the first piston and the other end of the push block contacting the locking block.

[0013] Furthermore, the door opening assembly also includes a first air guide pipe, a second air cylinder, a second piston, a push plate, a cross slider, and a push rod; the first air cylinder is fixedly connected to the top of one end near the push block, and the second air cylinder is fixedly connected to the inside of the top of the door frame, with one end of the second air cylinder communicating with the first air cylinder through the first air guide pipe; when the first piston pushes the block out of the door frame through the push block, the first piston exceeds the first air guide pipe, and the gas in the first air cylinder flows into the second air cylinder through the first air guide pipe; the second piston is slidably connected inside the second air cylinder, and the push plate is fixedly connected to the end of the second piston; a third sliding groove is provided at the top of the door frame, and a cross slider is slidably connected inside the third sliding groove, with the push plate located inside the third sliding groove and in contact with the cross slider; a push rod is rotatably connected to one end of the cross slider near the pneumatic door, and one end of the push rod is rotatably connected to the top of the pneumatic door.

[0014] Furthermore, the sound-generating assembly includes a second air duct, a sound-generating tube, a reed, and a megaphone. The second air duct is fixedly connected to the top of the end of the second air duct near the push plate, and the sound-generating tube is fixedly connected inside the door frame. The sound-generating tube communicates with the second air duct through the second air duct. When the second piston pushes the cross slider through the push plate, causing the push rod to fully open the pneumatic door, the second piston exceeds the second air duct, and the gas in the second air duct flows into the sound-generating tube through the second air duct. A reed is fixedly connected inside the sound-generating tube. The reed is made of an elastic metal material, and a megaphone is fixedly connected to the end of the sound-generating tube away from the second air duct. The megaphone has a horn-shaped design.

[0015] Furthermore, an air pump is fixedly connected to the outside of the room. The output end of the air pump is connected to the first air cylinder through a third air guide pipe. A vent valve is fixedly connected to the middle of the third air guide pipe through a vent pipe.

[0016] The beneficial effects of this invention compared to the prior art are as follows:

[0017] 1. Comprehensively enhance safety protection capabilities and reduce accident risks:

[0018] This invention addresses the shortcomings of traditional doors and windows that cannot automatically respond to gas leaks by constructing a complete safety protection system through a multi-linkage design. When the gas alarm detects a leak, a dual-axis motor synchronously drives the window opening assembly and valve. The outward-opening window opens rapidly under the action of the window push rod, while the valve operator closes the gas pipeline valve under the pull of the rope, cutting off the gas source and establishing a ventilation channel. This dual action of "closing the valve and opening the window" can curb the rise in gas concentration at the first moment, solving the safety hazards caused by the lag of traditional manual operation. In addition, the pneumatic door opens automatically under the action of the door opening assembly, forming a convection path with the outward-opening window. Combined with the forced ventilation of the fan blades, it significantly accelerates the diffusion of gas and greatly reduces the probability of accidents such as explosions and poisoning.

[0019] 2. Multi-dimensional warning mechanism to expand the scope of early warning:

[0020] To address the issue of single-mode warnings being susceptible to environmental interference, this invention innovatively employs a dual warning design combining visual and auditory elements. When an outward-opening window is opened, a limiting component releases a ribbon, which flutters dramatically under the influence of airflow from the fan blades, visually alerting people at a distance outdoors. Once the pneumatic door is fully opened, a sound-generating component amplifies the sound through reed vibrations and a loudspeaker, creating a continuous sound that covers the perimeter of the room and the indoor area. This combined warning system overcomes the limitations of traditional alarms in terms of sound propagation, ensuring that even in noisy environments or high-rise settings, nearby personnel can quickly detect danger, buying valuable time for rescue.

[0021] 3. Compatible with both automated and manual operation, enhancing flexibility of use:

[0022] The core functions of the device are all automatically completed by power components such as motors and air pumps, without the need for manual intervention, making it particularly suitable for unattended scenarios (such as when someone is briefly away from the kitchen). At the same time, the design retains a manual operation interface: the pneumatic door can be mechanically unlocked by turning the handle to drive the shaft, with the assistance of a torsion spring, meeting the needs of manual opening and closing in emergency situations. This "automatic priority + manual backup" mode not only adapts to the development trend of smart homes, but also takes into account the reliability in the event of sudden failures, improving the applicability in different scenarios.

[0023] 4. Highly efficient structural linkage, optimizing the coordination between ventilation and warning systems:

[0024] The precise coordination of each component makes the function more efficient. In the window opening component, the vertical transmission of the active and driven cone wheels ensures that the outward-opening windows open synchronously, and the connecting plate drives the fan frame to rotate so that the fan blades are precisely aligned with the window, improving the exhaust efficiency compared to traditional natural ventilation. The limiting component, through the linkage of the push block and the baffle, allows the ribbon to automatically unfold at the same time as the window opens, and the ribbon interacts with the airflow of the fan blades to enhance the visual warning effect. In the door opening component, the step-by-step ventilation design of the first and second air cylinders makes the pneumatic door unlocking and full opening a continuous action, which ultimately triggers the sound-emitting component to achieve a seamless connection of "alarm upon door opening" and avoids warning failure caused by functional delay.

[0025] In summary, safety doors and windows used for automatic alarm and opening of gas leaks are household safety devices that integrate detection, response, and warning functions. They are mainly used in indoor environments where gas is used, such as kitchens. Their core function is to automatically open doors and windows for ventilation through mechanical and pneumatic mechanisms when a gas leak is detected, thereby reducing the concentration of gas in the room. At the same time, they issue warnings through ribbons, sound-emitting components, etc., to remind people inside and outside the room to take timely action, thereby reducing the occurrence of safety accidents such as gas poisoning and explosions, and providing protection for household gas safety.

[0042] 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.

[0043] See Figures 1 to 15This embodiment proposes a safety door and window for automatic alarm and opening in case of gas leakage. The safety door and window includes a window frame 2, installed at one end of a room 1, with outward-opening windows 3 symmetrically installed inside the window frame 2; a door frame 4 is installed at the end of the room 1 away from the window frame 2, with a pneumatic door 5 installed inside the door frame 4; a stove 6 is installed on one side of the room 1, and a gas alarm 7 for detecting the gas concentration in the room 1 is installed at the top of the side of the room 1 closest to the stove 6; a gas pipe 8 is installed on one side of the stove 6, with a valve 9 installed in the middle of the gas pipe 8; the room 1... A sash frame 10 is rotatably connected to one end near the window frame 2. Under normal circumstances, the sash frame 10 is perpendicular to the window frame 2. Sash blades 11 are symmetrically installed inside the sash frame 10. A drive motor 56 is symmetrically fixedly connected to the sash frame 10. The drive motor 56 is used to drive the corresponding sash blades 11 to rotate. A window opening assembly is installed inside the room 1. When a gas leak occurs, the window opening assembly will open the outward-opening window 3 and rotate the sash frame 10 to a state parallel to the window frame 2, so that the sash blades 11 are aligned with the window frame 2. At the same time, the drive motor 56 starts and drives the sash blades 11 to rotate, accelerating airflow and reducing the gas concentration in the room 1.

[0044] Each of the two outward-opening windows 3 has a storage slot 12 at one of its facing ends. A ribbon 13 is installed inside each storage slot 12. One end of the ribbon 13 is fixedly connected to the inner wall of the storage slot 12, while the other end is free. The ribbon 13 serves to alert passersby that a gas leak has occurred inside room 1. A limiting component is installed inside the outward-opening window 3. When a gas leak occurs, the limiting component releases the restriction on the ribbon 13 and pushes it out. The ribbon 13 cooperates with the fan blade 11, allowing it to flutter outdoors and preventing damage from drafts. When room 1 is on a high floor or affected by outdoor noise, wind speed, or other factors, passersby outdoors will not be able to hear the alarm. A door opening assembly is installed on the side of room 1 near the door frame 4. When a gas leak occurs, the door opening assembly unlocks the pneumatic door 5 and opens it, allowing airflow between the door frame 4 and the window frame 2. This, combined with the airflow guided by the fan blades 11, promotes the discharge of gas. A sound-emitting assembly is installed inside the door frame 4. When the pneumatic door 5 is fully opened, the sound-emitting assembly will emit a sound to alert people nearby outdoors or indoors that a gas leak has occurred in room 1.

[0045] When the gas alarm 7 in room 1 detects that the gas concentration exceeds the safety threshold, it will immediately send an electrical signal, triggering the entire safety door and window system to work together. On one hand, the window opening component activates the outward-opening window 3 to rotate 90 degrees, causing the sash frame 10 to rotate 90 degrees and align the sash blade 11 with the window frame 2. At the same time, the opening of the outward-opening window 3 will trigger the limit component, which will release the limit on the ribbon 13 and push the ribbon 13 out, alerting people outside to the gas leak. In addition, the window opening component will also close the valve 9 during operation. On the other hand, the door opening component unlocks the pneumatic door 5 and opens the pneumatic door 5, allowing air convection in room 1. At the same time, the door opening component will also work with the sound-emitting component to emit a sound, alerting people inside to the gas leak.

[0046] like Figures 1 to 4 As shown, the window opening assembly includes: a rotating rod 14, a driving cone wheel 15, a driven cone wheel 16, a push-window rod 17, and a connecting plate 18. The rotating rod 14 is rotatably connected inside the window frame 2, and both ends of the rotating rod 14 are fixedly connected to the driving cone wheel 15. The driven cone wheel 16 is symmetrically rotatably connected to the top of the inner wall of the window frame 2, and the driving cone wheel 15 meshes with the driven cone wheel 16. The bottom of each driven cone wheel 16 is fixedly connected to the push-window rod 17, which is used to push the outward-opening window 3 to rotate. The connecting plate 18 is fixedly connected to the middle of the rotating rod 14, and the top of the connecting plate 18 is fixedly connected to the sash frame 10. The push-window rod 17 has an L-shaped design. A dual-axis motor 51 is fixedly connected inside the room 1, and one output end of the dual-axis motor 51 is fixedly connected to the rotating rod 14.

[0047] The core function of the window opening assembly is to automatically open the outward-opening window 3 when there is a gas leak, and simultaneously adjust the direction of the fan blades 11 to enhance the ventilation effect. When the dual-axis motor 51 starts, one of its output ends drives the rotating rod 14 to rotate, and the active cone wheels 15 at both ends of the rotating rod 14 rotate accordingly. Since the active cone wheel 15 meshes with the driven cone wheel 16 at the top of the window frame 2, the vertical rotational motion is converted into horizontal transmission, causing the push window rod 17 at the bottom of the driven cone wheel 16 to rotate synchronously. The push window rod 17 adopts an L-shaped design, and during its rotation, it will directly act on the edge of the outward-opening window 3, pushing the two outward-opening windows 3 to rotate outward around the window frame 2 as the axis, so as to realize the air circulation between the room 1 and the outside.

[0048] At the same time, the connecting plate 18 in the middle of the rotating rod 14 will rotate together with the rotating rod 14. Since the connecting plate 18 is fixedly connected to the sash frame 10, the sash frame 10 will rotate 90 degrees under the drive of the connecting plate 18 until it is on the same plane as the initial state of the window frame 2 (the initial state is perpendicular). At this time, the fan blade 11 is just aligned with the ventilation opening formed after the outward opening window 3 is opened. Subsequently, the drive motor 56 on the sash frame 10 starts, driving the fan blade 11 to rotate at high speed, accelerating the discharge of leaked gas in room 1, and reducing the indoor gas concentration through forced convection.

[0049] Another output end of the dual-axis motor 51 is fixedly connected to a rope winding roller 52, and a rope 53 is wound around the outer wall of the rope winding roller 52; a valve handle 54 is installed on the top of the valve 9, and the valve handle 54 is used to control the opening and closing of the valve 9; a guide roller 55 is rotatably connected inside the room 1, and one end of the rope 53 passes around the guide roller 55 and is fixed to the end of the valve handle 54. The guide roller 55 prevents the rope 53 from rubbing against the wall of the room 1 and causing greater wear.

[0050] After the other output end of the dual-axis motor 51 is started, it drives the rope winding roller 52 to rotate, and the rope 53 wrapped around the outer wall of the rope winding roller 52 is gradually tightened. One end of the rope 53 passes around the guide roller 55 fixed inside the room 1 (the guide roller 55 changes the direction of force on the rope 53 to avoid the rope 53 from being damaged by friction with the wall), and is fixedly connected to the end of the valve handle 54 at the top of the valve 9 of the gas pipeline 8. As the rope 53 tightens, it generates a pulling force on the valve handle 54, causing the valve handle 54 to rotate around the axis of the valve 9 until the valve 9 is completely closed, cutting off the gas supply to the gas pipeline 8, preventing the gas from continuing to leak from the source, and providing a safe environment for subsequent treatment.

[0051] like Figures 5 to 9 As shown, the limiting assembly includes: a first slide groove 19, a pusher block 20, a first compression spring 21, a first slot 22, a first locking plate 23, a baffle 24, a second locking plate 25, a second slide groove 26, a connecting slider 27, a second compression spring 28, an inclined groove 29, an inclined push block 30, and a third compression spring 31.

[0052] The interior of the outward-opening window 3 is provided with a first sliding groove 19. A pusher block 20 for pushing the ribbon 13 out of the storage slot 12 is slidably connected within the first sliding groove 19. A first compression spring 21 is fixedly connected to one end of the pusher block 20, and the end of the first compression spring 21 away from the pusher block 20 is fixedly connected to the outward-opening window 3. A first locking slot 22 is provided at the top of the pusher block 20. A first locking plate 23 is slidably connected inside the outward-opening window 3, and the first locking plate 23 engages with the first locking slot 22. At one end of the storage slot 12... A baffle 24 is rotatably connected to the outer opening window 3. The bottom end of the baffle 24 is rotatably connected to the outer opening window 3. The baffle 24 is used to prevent the ribbon 13 from sliding out of the storage slot 12. A second locking plate 25 is slidably connected inside the outer opening window 3. The second locking plate 25 is engaged with the top end of the baffle 24. A second sliding groove 26 is opened inside the outer opening window 3. A connecting slider 27 is slidably connected inside the second sliding groove 26. The two ends of the bottom of the connecting slider 27 are respectively fixed to the top ends of the first locking plate 23 and the second locking plate 25. The second sliding groove 26... A second compression spring 28 is fixedly connected to the top, and the bottom of the second compression spring 28 is fixed to the top of the connecting slider 27; a slanted groove 29 is opened in the middle of the first clamping plate 23, and a slanted push block 30 is slidably connected to one side of the outward opening window 3. The slanted push block 30 is inserted into the slanted groove 29, and the slanted push block 30 contacts the inclined surface of the slanted groove 29. When the window push rod 17 pushes the outward opening window 3, the window push rod 17 squeezes the slanted push block 30. The slanted push block 30 causes the first clamping plate 23 to move upward by squeezing the slanted groove 29, thereby allowing the window to pass through the slanted groove 29. The connecting slider 27 drives the second card plate 25 upward synchronously, releasing the limit of the baffle 24. At the same time, the pusher block 20 pushes out the free end of the ribbon 13. Both sides of the inclined pusher block 30 are fixedly connected to the third compression spring 31, and one end of the third compression spring 31 is fixedly connected to the outward opening window 3. The height of the side of the storage slot 12 near the baffle 24 is twice the height of the baffle 24. After the baffle 24 rotates 180 degrees, it enters the lower half of the storage slot 12 to avoid the baffle 24 affecting the fluttering of the ribbon 13.

[0053] The function of the limiting component is to automatically release the ribbon 13 during the opening of the outward-opening window 3 to visually alert outdoor personnel; when the window push rod 17 rotates to push the outward-opening window 3, one end of its L-shaped structure will press the inclined push block 30 inside the outward-opening window 3; after being pressed, the inclined push block 30 slides into the inside of the inclined groove 29, and its end contacts the inclined surface of the inclined groove 29 in the middle of the first card plate 23, converting the horizontal pressing force into a vertical upward thrust, so that the first card plate 23 moves upward along the inside of the outward-opening window 3.

[0054] After the first card plate 23 moves upward, its bottom end disengages from the first slot 22 at the top of the pusher block 20, releasing the restriction on the pusher block 20. At this time, the first compression spring 21 releases its elastic potential energy because it is no longer constrained, pushing the pusher block 20 to slide along the first slide groove 19 toward the storage groove 12. The end of the pusher block 20 directly acts on the free end of the ribbon 13, pushing the ribbon 13 out of the storage groove 12.

[0055] As the first card plate 23 moves upward, its top end drives the second card plate 25 to move upward synchronously via the connecting slider 27. The second card plate 25 disengages from the slot at the top of the baffle 24, releasing the baffle 24 from its restriction. During the process of pushing the ribbon 13 out, it will contact the baffle 24, pushing the baffle 24 to rotate 180 degrees upward around its bottom end as the axis, and finally enter the lower half of the storage slot 12 near the baffle 24 (this side is twice the height of the baffle 24, providing sufficient storage space for the baffle 24). This prevents the baffle 24 from obstructing the ribbon 13 from fluttering under the action of outdoor airflow, ensuring that people passing by outdoors can clearly see the ribbon 13 and know that a gas leak has occurred indoors.

[0056] like Figures 10 to 14 As shown, the door opening assembly includes: a pivot 32, a turntable 33, a torsion spring 34, a locking block 35, a connecting rod 36, a first air cylinder 37, a first piston 38, a flat push block 39, a first air guide pipe 40, a second air cylinder 41, a second piston 42, a push plate 43, a cross slider 45, and a push rod 46.

[0057] A rotating shaft 32 is rotatably connected to one end of the pneumatic door 5. Handles are fixedly connected to both ends of the rotating shaft 32. A turntable 33 is fixedly connected to the outer wall of the middle part of the rotating shaft 32. Torsion springs 34 are symmetrically fixedly connected to the outer wall of the rotating shaft 32, with opposite ends of the two torsion springs 34 fixedly connected to the pneumatic door 5. A locking block 35 is slidably connected to one end of the pneumatic door 5, engaging with the door frame 4. Connecting rods 36 are symmetrically installed between the locking block 35 and the turntable 33, with both ends of the connecting rods 36 rotatably connected to the sides of the locking block 35 and the turntable 33, respectively. A first air cylinder 37 is fixedly connected inside the door frame 4, and a first piston 38 is slidably connected inside the first air cylinder 37. A flat push block 39 is slidably connected inside the door frame 4, with one end of the flat push block 39 fixed to the first piston 38 and the other end of the flat push block 39 contacting the locking block 35. The top of the first air cylinder 37 is near the flat push block 39. A first air guide pipe 40 is fixedly connected, and a second air cylinder 41 is fixedly connected inside the top of the door frame 4. One end of the second air cylinder 41 is connected to the first air cylinder 37 through the first air guide pipe 40. When the first piston 38 pushes the locking block 35 out of the door frame 4 through the flat push block 39, the first piston 38 just exceeds the first air guide pipe 40, and the gas in the first air cylinder 37 flows into the second air cylinder 41 through the first air guide pipe 40. A second piston 42 is slidably connected inside the second air cylinder 41, and a push plate 43 is fixedly connected to the end of the second piston 42. A third sliding groove 44 is opened at the top of the door frame 4, and a cross slider 45 is slidably connected inside the third sliding groove 44. The push plate 43 is located inside the third sliding groove 44 and contacts the cross slider 45. A push rod 46 is rotatably connected to the end of the cross slider 45 near the pneumatic door 5, and one end of the push rod 46 is rotatably connected to the top of the pneumatic door 5.

[0058] The door opening assembly automatically opens the pneumatic door 5 via pneumatic transmission. Its operation is divided into two stages: unlocking and pushing. After a gas leak is triggered, the air pump 57 delivers gas to the first air cylinder 37 through the third air pipe 58. The gas pushes the first piston 38 in the first air cylinder 37 to move towards the locking block 35. The flat push block 39, which is fixed to the first piston 38, moves synchronously and contacts the locking block 35. As the gas continues to be input, the thrust generated by the flat push block 39 gradually increases, eventually pushing the locking block 35 out of the slot in the door frame 4, releasing the lock between the pneumatic door 5 and the door frame 4 (the locking block 35 was originally engaged with the door frame 4 to close and fix the pneumatic door 5).

[0059] When the locking block 35 is completely disengaged from the door frame 4, the first piston 38 moves just beyond the position of the first air guide pipe 40. At this time, the gas in the first air cylinder 37 flows into the second air cylinder 41 through the first air guide pipe 40. After the gas enters the second air cylinder 41, it pushes the second piston 42 to move. The push plate 43 at the end of the second piston 42 slides in the third slide groove 44 and contacts the cross slider 45. Since the cross slider 45 can only slide horizontally in the third slide groove 44, the pushing force of the push plate 43 drives the cross slider 45 to move closer to the pneumatic door 5. The cross slider 45 pushes the pneumatic door 5 through the push rod 46 rotatably connected to its end, so that the pneumatic door 5 rotates outward about one side of the door frame 4.

[0060] During this process, the rotation angle of the pneumatic door 5 gradually increases until it is fully open (usually 90 degrees). At this time, the cross slider 45 moves to the end of the third slide groove 44, and the push rod 46 is in the maximum extension state, ensuring that the opening angle of the pneumatic door 5 can meet the needs of rapid diffusion of indoor gas. When a gas alarm occurs, if it is necessary to manually open the pneumatic door 5, the handle can be turned to drive the rotating shaft 32 to rotate. The turntable 33 on the rotating shaft 32 pulls the locking block 35 into the pneumatic door 5 through the connecting rod 36. The torsion spring 34 stores force when the rotating shaft 32 rotates, which can open the pneumatic door 5. If it is necessary to manually close the pneumatic door 5, after closing the pneumatic door 5, the torsion spring 34 will assist the rotating shaft 32 to reset after releasing the handle, so that the locking block 35 is re-engaged with the door frame 4.

[0061] like Figure 10 , Figure 13 , Figure 14 , Figure 15As shown, the sound-generating assembly includes: a second air duct 47, a sound-generating cylinder 48, a reed 49, and a megaphone 50; the second air duct 47 is fixedly connected to the top of one end of the second air duct 41 near the push plate 43, and the sound-generating cylinder 48 is fixedly connected inside the door frame 4, with the sound-generating cylinder 48 communicating with the second air duct 47 through the second air duct 47; when the second piston 42 pushes the cross slider 45 through the push plate 43, causing the push rod 46 to fully open the pneumatic door 5, the second piston 42 just exceeds the second air duct 47, and the second air duct 48... The gas in the second gas cylinder 41 flows into the sound-emitting cylinder 48 through the second gas guide pipe 47. A reed 49 is fixedly connected inside the sound-emitting cylinder 48. The reed 49 is made of elastic metal material. A megaphone 50 is fixedly connected to the end of the sound-emitting cylinder 48 away from the second gas guide pipe 47. The megaphone 50 is designed in the shape of a horn. When the airflow passes through, the reed 49 will vibrate under the action of the airflow, thereby emitting sound. The sound is amplified by the megaphone 50 and transmitted into the house to remind the people in the house that there is a gas leak in room 1.

[0062] The sound-generating component is activated after the pneumatic door 5 is fully opened, alerting people around it with a sound signal. When the pneumatic door 5 is fully open, the second piston 42 moves just beyond the position of the second air guide tube 47 under the push of the gas. At this time, the gas in the second air cylinder 41 flows into the sound-generating cylinder 48 through the second air guide tube 47.

[0063] After the airflow enters the sound-emitting tube 48, it impacts the internally fixed reed 49 (made of elastic metal material), causing the reed 49 to vibrate at a high frequency. During the vibration, it resonates with the air to form sound. Because the reed 49 has good elasticity, its vibration frequency is stable and can produce a continuous and clear alarm sound. The end of the sound-emitting tube 48 away from the second air duct 47 is connected to a horn-shaped megaphone 50. The megaphone 50, through its gradually changing cross-section design, concentrates and amplifies the sound energy generated by the vibration of the reed 49, making the sound propagation range wider and ensuring that people near room 1 (including other indoor areas and outdoors) can detect the gas leak accident in time.

[0064] like Figures 10 to 12 As shown, an air pump 57 is fixedly connected to the outside of room 1. The output end of the air pump 57 is connected to the first air cylinder 37 through the third air guide pipe 58. A vent valve 60 is fixedly connected to the middle of the third air guide pipe 58 through the vent pipe 59.

[0065] After the gas leak accident is dealt with, the device needs to be restored to its initial state. At this time, open the vent valve 60 in the middle of the third gas pipe 58, and the compressed gas in the first gas cylinder 37, the second gas cylinder 41 and the sound-emitting cylinder 48 will be discharged through the vent pipe 59, and the gas pressure will decrease; then close the pneumatic valve 5 to discharge the remaining gas and close the vent valve 60 to complete the discharge of compressed gas.

[0066] The working principle of this invention is as follows:

[0067] 1. The working principle of opening outward window 3 and releasing ribbon 13:

[0068] Inside room 1, when a gas leak occurs in the gas pipe 8 near the stove 6, and the concentration of the leaked gas reaches the warning threshold of the gas alarm 7, the gas alarm 7 will immediately send a signal, triggering the dual-axis motor 51 to start. One of the outputs of the dual-axis motor 51 will drive the rotating rod 14 in the window opening assembly to start rotating, and the active cone wheel 15 fixed at both ends of the rotating rod 14 will also rotate synchronously. Since the active cone wheel 15 meshes with the driven cone wheel 16 at the top of the inner wall of the window frame 2, the rotation of the active cone wheel 15 will drive the driven cone wheel 16 to rotate together, thereby causing the push window rod 17 fixed at the bottom of the driven cone wheel 16 to start rotating. The push window rod 17 is L-shaped, and during its rotation, it will contact the edge of the outward opening window 3 and push the two outward opening windows 3 to rotate outward about the window frame 2 as the axis, so as to realize the air circulation between the inside of room 1 and the outside.

[0069] As the window push rod 17 pushes the outward-opening window 3 to rotate, the connecting plate 18 fixed in the middle of the rotating rod 14 will rotate together with the rotating rod 14. Because the connecting plate 18 is fixedly connected to the sash frame 10, the sash frame 10 will rotate 90 degrees under the drive of the connecting plate 18 until the sash frame 10 and the window frame 2 are on the same plane. At this time, the fan blade 11 installed inside the sash frame 10 is exactly aligned with the window formed after the outward-opening window 3 is opened. Subsequently, the drive motor 56 fixed in the middle of the sash frame 10 starts, driving the fan blade 11 to rotate at high speed, accelerating the discharge of leaked gas in the room 1.

[0070] During the process of pushing the outward-opening window 3 by the push rod 17, one end of the L-shaped structure of the push rod 17 will squeeze the inclined push block 30 inside the outward-opening window 3. After being squeezed, the inclined push block 30 will slide into the inclined groove 29. The end of the inclined push block 30 will contact the inclined surface of the inclined groove 29 in the middle of the first clamping plate 23, converting the horizontal squeezing force into a vertical upward thrust, causing the first clamping plate 23 to move upward along the inside of the outward-opening window 3. After the first clamping plate 23 moves upward, its bottom end will disengage from the first clamping groove 22 at the top of the push band block 20, releasing the restriction on the push band block 20. At this time, the first compression spring 21 in the compressed state will release elastic potential energy, pushing the push band block 20 to slide along the first sliding groove 19 towards the storage groove 12. The push band block 20 will push the ribbon 13 inside the storage groove 12 outward.

[0071] Simultaneously, when the first card plate 23 moves upward, its top end drives the second card plate 25 to move upward synchronously within the second slide groove 26 via the connecting slider 27. After the second card plate 25 moves upward, it will disengage from the top end of the baffle 24, releasing the restriction on the baffle 24. When the ribbon 13 is pushed out, it will contact the baffle 24 and push the baffle 24 to rotate 180 degrees upward with its bottom end and the connection point of the outward opening window 3 as the axis. Since the height of the storage groove 12 near the baffle 24 is twice that of the baffle 24, the baffle 24 will enter the lower half of the storage groove 12 after rotation, without hindering the movement of the ribbon 13. When the push window rod 17 no longer presses the inclined push block 30, the third compression spring 31 on both sides of the inclined push block 30 will release elastic potential energy and push the inclined push block 30 to reset. Under the action of the second compression spring 28, the connecting slider 27 will drive the first card plate 23 and the second card plate 25 to reset.

[0072] The other output end of the dual-axis motor 51 drives the rope winding roller 52 to rotate. The rope 53 wound around the outer wall of the rope winding roller 52 will be gradually tightened. One end of the rope 53 passes around the guide roller 55 installed inside the room 1 and is fixedly connected to the end of the valve handle 54 on the top of the valve 9. As the rope 53 tightens, it will pull the valve handle 54 to rotate, thereby closing the valve 9 and cutting off the gas supply in the gas pipeline 8.

[0073] 2. Working principle of opening pneumatic door 5 and emitting an alarm:

[0074] When the gas alarm 7 sends a signal, the gas pump 57 installed on the outside of room 1 will start. The gas pump 57 delivers gas to the first gas cylinder 37 through the third gas pipe 58. The gas pushes the first piston 38 inside the first gas cylinder 37 to move closer to the locking block 35. The flat push block 39, which is fixedly connected to the first piston 38, will also move synchronously. During the movement, the flat push block 39 will contact the locking block 35 and push the locking block 35 to slide into the pneumatic door 5, so that the locking block 35 is disengaged from the door frame 4, and the lock between the pneumatic door 5 and the door frame 4 is released.

[0075] When the locking block 35 is completely disengaged from the door frame 4, the first piston 38 moves just beyond the position of the first air guide tube 40. At this time, the gas in the first air cylinder 37 flows into the second air cylinder 41 through the first air guide tube 40, pushing the second piston 42 inside the second air cylinder 41 to move closer to the push plate 43. The second piston 42 will drive the push plate 43 to move synchronously. When the push plate 43 moves in the third slide groove 44, it will contact the cross slider 45 and push the cross slider 45 to slide in the third slide groove 44. During the movement of the cross slider 45, it will drive the pneumatic door 5 to rotate outward with its connection edge with the door frame 4 as the axis until the pneumatic door 5 is fully opened.

[0076] When the pneumatic door 5 is fully opened, the second piston 42 moves just beyond the position of the second air guide tube 47. The gas in the second air cylinder 41 flows into the sound-emitting tube 48 through the second air guide tube 47. After the airflow enters the sound-emitting tube 48, it will impact the internally fixed reed 49, causing the elastic metal reed 49 to vibrate. The vibrating reed 49 will emit a sound. The sound is amplified by the loudspeaker 50 at the end of the sound-emitting tube 48 and then propagated to alert people near room 1 that there is a gas leak.

[0077] When the pneumatic door 5 needs to be opened manually, turning the handles at both ends of the rotating shaft 32 will cause the rotating shaft 32 and the turntable 33 in the middle of the rotating shaft 32 to rotate. When the turntable 33 rotates, it will pull the locking block 35 into the pneumatic door 5 through the connecting rod 36, so that the locking block 35 is disengaged from the door frame 4. At the same time, the torsion spring 34 on the outer wall of the rotating shaft 32 will be twisted and stored. When the pneumatic door 5 needs to be closed, after the pneumatic door 5 is closed, the handles are released and the torsion spring 34 will drive the rotating shaft 32, the turntable 33 and the locking block 35 to return to their original positions.

[0078] After the gas leak is dealt with, open the vent valve 60 on the vent pipe 59. The gas in the first gas cylinder 37, the second gas cylinder 41 and the sound-emitting cylinder 48 will be discharged through the vent pipe 59. Then close the pneumatic door 5 and the vent valve 60 to restore the door opening assembly and the sound-emitting assembly to their initial state.

[0079] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. It should not be considered that the specific embodiments of the present invention are limited to this. For those skilled in the art, several simple deductions or substitutions can be made without departing from the present invention, and all of these should be considered to fall within the scope of patent protection determined by the submitted claims.
