Technical Field
[0001] This invention relates to the field of fire-fighting equipment technology, specifically to an intelligent fire-fighting window opener that can prevent hand pinching. Background Technology
[0002] Fire-fighting window openers are electric automatic window opening devices that have obtained fire protection qualifications through testing and certification by the National Fire Electronic Testing Center. They can automatically open windows in the event of a fire or other emergency to facilitate people's rapid escape. Currently, they have been put into use in many large shopping malls or upscale residential communities.
[0003] Winters in northern my country are extremely cold and long, and people there generally use gas heating. While this keeps the indoors warm, prolonged use can cause the connections between the heating equipment and the gas pipes to loosen, or the gas valves to be damaged from being open for extended periods. Both of these situations can lead to gas leaks. Furthermore, because of the low winter temperatures, people tend to close their windows at night, especially the elderly. If a gas leak occurs while the elderly are asleep, it can threaten their lives and cause irreparable harm. Additionally, in the event of a fire, people will evacuate to a safe location as quickly as possible, leaving no time to close the windows. However, if the windows remain open, outside air will continuously enter the room, fueling the fire and greatly hindering subsequent firefighting and rescue efforts.
[0004] Therefore, the inventor has invented an intelligent fire-fighting window opener that can prevent hand pinching. When a gas leak occurs at night, it automatically opens the window to promptly vent the gas inside the house and simultaneously sends an alarm to sleeping people. When a fire occurs indoors due to a malfunction of the heating equipment, it can automatically close and lock the open window to prevent outside air from entering the house and causing the fire to spread further. It can effectively solve the above problems. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides an intelligent fire-fighting window opener that prevents hand pinching. It automatically opens windows to expel gas from the room and simultaneously alerts sleeping individuals when a gas leak occurs. Furthermore, it automatically closes and locks the open windows to prevent outside air from entering and spreading the fire if a fire breaks out due to a heating equipment malfunction. This invention solves the problems of carbon monoxide poisoning and fires that frequently occur when using gas heating equipment in northern my country during winter.
[0007] (II) Technical Solution
[0008] To achieve the aforementioned goals of automatically opening windows to promptly vent gas from the room and simultaneously alerting sleeping individuals when a gas leak occurs indoors, and automatically closing and locking the open windows to prevent outside air from entering and further spreading the fire when the gas concentration in the indoor air is too high and causes a fire, this invention provides the following technical solution: an intelligent fire-fighting window opener with anti-pinch function, comprising a window frame, a window glass rotatably connected to the upper end of the window frame, a mounting base at the lower end of the window frame, a sensor pipe at the lower end of the mounting base, alarms on both the left and right sides of the mounting base, a gas safety mechanism movably installed inside the mounting base, and an automatic fire closing mechanism at the lower end of the mounting base.
[0009] Preferably, the gas safety mechanism includes a control slot, a methane detection block slidably connected inside the control slot, a return spring fixedly connected to the upper end of the methane detection block, a flexible connecting rod rotatably connected to the middle of the methane detection block, a connecting slot above the control slot, the control slot being vertically located at the lower end of the mounting base, the upper end of the methane detection block being located inside the control slot and slidably connected to the control slot, the lower end of the methane detection block extending into the interior of the sensing pipe, the lower end of the return spring being fixedly connected to the upper end of the methane detection block, the upper end of the return spring being fixedly connected to the inner wall of the control slot, the connecting slot communicating with the interior of the control slot, one end of the flexible connecting rod being rotatably connected to the methane detection block, and the other end of the flexible connecting rod extending out through the connecting slot. Thus, in the initial state, the methane detection block will extend its lower end into the interior of the sensing pipe under its own weight and the action of the return spring. When the flexible connecting rod moves upward along the connecting slot, it will cause the methane detection block to retract upward.
[0010] Preferably, the mounting base has vertical clearance cavities on both the left and right sides. A push rod is slidably connected inside the clearance cavity. A drive gear is movably mounted on the upper end of the clearance cavity. A buffer pad is fixedly mounted on the lower end of the clearance cavity. A rectangular protrusion is provided on the lower end of the push rod. The upper end of the clearance cavity is open. The upper end of the push rod is fixedly connected to the lower end of the window glass. The outer surface shape of the push rod matches the outer surface shape of the drive gear. Thus, when the drive gear rotates, the push rod can move up or down along the inner wall of the clearance cavity. When the push rod moves up, it pushes the window glass outward. When the push rod moves down, it causes the window glass to retract inward.
[0011] Preferably, a mounting groove is horizontally provided on one side of the inner wall of the clearance cavity, and an alarm switch is slidably connected inside the mounting groove. An electric motor is installed inside the mounting base, and the alarm switch is electrically connected to the power supply through a wire. Thus, when the push rod moves upward, the rectangular protrusion will press the alarm switch, and the alarm switch will be turned on due to the pressure, causing the alarm to sound.
[0012] Preferably, the methane detection block is equipped with a methane sensor inside, and the flexible connecting rod is made of a flexible and bendable material. When methane gas appears inside the sensing pipe, the methane sensor will quickly detect the presence of methane gas and, in cooperation with the electric motor, cause the drive gear to rotate. After the drive gear rotates, the push rod will move upward.
[0013] Preferably, the automatic fire shut-off mechanism includes a pneumatic cavity, a heat-conducting block is fixedly installed at the lower end of the pneumatic cavity, a movable slider is slidably connected inside the pneumatic cavity, a push switch is provided at the upper end of the pneumatic cavity, the pneumatic cavity is vertically opened inside the mounting base, the lower end of the heat-conducting block extends into the interior of the sensing pipe, the outer surface of the movable slider is tightly fitted with the inner wall of the pneumatic cavity, and the push switch is electrically connected to a power source through an electric wire. Thus, when the temperature inside the sensing pipe rises, the movable slider will move vertically upward along the inner wall of the pneumatic cavity. When the movable slider moves to the top of the pneumatic cavity, the push switch will be turned on.
[0014] Preferably, the mounting base has a locking groove inside, a locking protrusion is slidably connected inside the locking groove, a drive screw is movably disposed inside the locking groove, the locking groove is connected to the interior of the clearance cavity, one end of the drive screw extends into the interior of the locking protrusion and is threadedly connected to the locking protrusion, so that when the push switch is turned on, the locking protrusion will extend into the interior of the clearance cavity under the action of the drive screw, and then the locking protrusion will cooperate with the push rod to limit the position of the push rod.
[0015] Preferably, the left end of the sensing pipe is connected to the indoor air, and a control valve housing is fixedly installed at the right end of the sensing pipe. A blocking ball is movably installed inside the control valve housing, and a push spring is fixedly connected to the right end of the blocking ball. In the initial state, the blocking ball is in a blocking state of the control valve housing. One end of the push spring is fixedly connected to the blocking ball, and the other end of the push spring is fixedly connected to the inner wall of the control valve housing. The push spring is always in a compressed state, so that the gas inside the sensing pipe can only flow from the left side of the control valve housing to the right side of the control valve housing, realizing the effect of unidirectional gas flow.
[0016] Preferably, the mounting base is equipped with an internal power supply, so that when a power outage occurs due to a fire, the internal power supply can continue to supply power to the electric motor, ensuring that the push rod can retract into the interior of the clearance cavity in a timely manner.
[0017] The upper end of the connecting groove is connected to the interior of the pneumatic cavity, and the lower end of the connecting groove is connected to the interior of the control groove. The movable slider and the methane detection block are movably connected by a flexible connecting rod. The connection between the connecting groove and the pneumatic cavity is sealed. Thus, when the movable slider moves upward along the pneumatic cavity, it can move the methane detection block upward along the inner wall of the control groove through cooperation with the flexible connecting rod.
[0018] (III) Beneficial Effects
[0019] Compared with the prior art, the present invention provides an intelligent fire-fighting window opener that can prevent hand pinching, and has the following beneficial effects:
[0020] 1. This intelligent fire-fighting window opener, which can prevent hand pinching, is equipped with a gas safety mechanism. When a gas leak occurs indoors, the drive gear will rotate under the drive of an electric motor. When the drive gear rotates, it will move the push rod vertically upward through cooperation with the push rod. During the upward movement of the push rod, the window will be opened. At the same time, through cooperation with the alarm switch, the alarm will be sounded. Thus, it achieves the effect of automatically opening the window to reduce the gas concentration indoors when there is a gas leak, and at the same time sounding the alarm to wake up people who are sleeping.
[0021] 2. This intelligent fire-fighting window opener, which can prevent hand pinching, is equipped with an automatic fire-fighting closing mechanism. When a fire is caused by excessive gas concentration indoors, the interaction between the heat-conducting block and the movable slider will cause the push switch to be pressed and connected. After the push switch is connected, the drive gear will rotate in the opposite direction. During the rotation of the drive gear, the window will be closed, and the methane detection block will be automatically retracted during the window closing process. This not only prevents outside air from entering the room and causing the fire to intensify, but also prevents the methane detection block from being overheated and exploding.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0035] Please see Figures 1-11A smart fire-fighting window opener capable of preventing hand pinching includes a window frame 1, a window glass 2 rotatably connected to the upper end of the window frame 1, a mounting base 3 at the lower end of the window frame 1, a sensor pipe 4 at the lower end of the mounting base 3, alarms 5 on both sides of the mounting base 3, a gas safety mechanism 6 movably installed inside the mounting base 3, and an automatic fire-closing mechanism 7 at the lower end of the mounting base 3. The gas safety mechanism 6 includes a control groove 601, which is vertically located at the lower end of the mounting base 3. A methane detection block 602 is slidably connected inside the control groove 601, with its upper end located inside and slidably connected to the control groove 601, and its lower end extending into the sensor pipe. Inside channel 4, a reset spring 603 is fixedly connected to the upper end of the methane detection block 602. The lower end of the reset spring 603 is fixedly connected to the upper end of the methane detection block 602, and the upper end of the reset spring 603 is fixedly connected to the inner wall of the control groove 601. A flexible connecting rod 604 is rotatably connected to the middle of the methane detection block 602. One end of the flexible connecting rod 604 is rotatably connected to the methane detection block 602, and the other end of the flexible connecting rod 604 passes through the connecting groove 605 above the control groove 601. The connecting groove 605 is connected to the inside of the control groove 601. Thus, in the initial state, the lower end of the methane detection block 602 will extend into the inside of the sensing channel 4 under its own weight and the action of the reset spring 603. When the flexible connecting rod 604... 4. When moving upward along the connecting groove 605, the methane detection block 602 will retract upward. The mounting base 3 has vertically formed clearance cavities 606 on both the left and right sides. The upper end of the clearance cavity 606 is open. A push rod 607 is slidably connected inside the clearance cavity 606. The upper end of the push rod 607 is fixedly connected to the lower end of the window glass 2, and the outer surface shape of the push rod 607 matches the outer surface shape of the drive gear 608. The drive gear 608 is movably mounted on the upper end of the clearance cavity 606. A buffer pad 612 is fixedly mounted on the lower end inside the clearance cavity 606. A rectangular protrusion 613 is provided on the lower end of the push rod 607, so that when the drive gear 608 rotates, the push rod 607 can move along the clearance cavity 606. The inner wall moves upward or downward. When the push rod 607 moves upward, it pushes the window glass 2 outward; when the push rod 607 moves downward, it causes the window glass 2 to retract inward. A mounting groove 609 is horizontally opened on one side of the inner wall of the clearance cavity 606. An alarm switch 610 is slidably connected inside the mounting groove 609. The alarm switch 610 is electrically connected to a power source via a wire. An electric motor 611 is installed inside the mounting base 3. Thus, when the push rod 607 moves upward, the rectangular protrusion 613 presses against the alarm switch 610. When the alarm switch 610 is pressed and activated, the alarm 5 sounds. A methane sensor is installed inside the methane detection block 602. The flexible connecting rod 604 is made of a flexible and bendable material.Therefore, when methane gas appears inside the sensing pipe 4, the methane sensor will quickly detect its presence and, in conjunction with the electric motor 611, cause the drive gear 608 to rotate. The rotation of the drive gear 608 will then cause the push rod 607 to move upwards.
[0036] Working principle:
[0037] In the initial state, the push rod 607 is located inside the avoidance cavity 606, the left end of the sensing pipe 4 is connected to the indoor environment, and the right end of the sensing pipe 4 is connected to the external environment.
[0038] When a gas leak occurs indoors, the air containing gas will enter the interior of the sensing pipe 4. Since the main component of the gas is methane, the gas will come into contact with the methane detection block 602 that extends into the sensing pipe 4 after entering the gas. The methane detection block 602 is equipped with a methane sensor. Therefore, when the gas comes into contact with the methane detection block 602, the electric motor 611 will start to work.
[0039] When the electric motor 611 starts working, it will cause the drive gear 608 to rotate. When the drive gear 608 rotates, it will cooperate with the push rod 607 to extend the push rod 607 outward. When the push rod 607 extends outward, it will push the window glass 2 outward, and then the window will be opened.
[0040] Additionally, as the push rod 607 moves upward along the clearance cavity 606, the rectangular protrusion 613 will come into contact with the alarm switch 610. When the alarm switch 610 is pressed, it will be turned on, and then the alarm 5 will sound an alarm to wake up people who are asleep.
[0041] This allows the system to promptly open windows to reduce indoor gas concentration when a gas leak occurs, and simultaneously sound a loud alarm to wake sleeping individuals, preventing the risk of carbon monoxide poisoning or suffocation in elderly people due to excessively high indoor gas concentrations. Example 2:
[0042] Please see Figures 1-11A smart fire-fighting window opener capable of preventing hand pinching includes a window frame 1, a window glass 2 rotatably connected to the upper end of the window frame 1, a mounting base 3 at the lower end of the window frame 1, a sensor pipe 4 at the lower end of the mounting base 3, alarms 5 on both sides of the mounting base 3, a gas safety mechanism 6 movably installed inside the mounting base 3, and an automatic fire closing mechanism 7 at the lower end of the interior of the mounting base 3. The automatic fire closing mechanism 7 includes a pneumatic cavity 701, which is vertically opened inside the mounting base 3, and a heat-conducting device is fixedly installed at the lower end of the inner cavity of the pneumatic cavity 701. Block 702, the lower end of which extends into the interior of the sensing pipe 4, is a heat-conducting block 702. A movable slider 703 is slidably connected inside the pneumatic cavity 701. The outer surface of the movable slider 703 is tightly fitted against the inner wall of the pneumatic cavity 701. A push switch 704 is located at the upper end of the pneumatic cavity 701. The push switch 704 is electrically connected to a power source via a wire. When the temperature inside the sensing pipe 4 rises, the movable slider 703 moves vertically upwards along the inner wall of the pneumatic cavity 701. When the movable slider 703 reaches the top of the pneumatic cavity 701, it triggers the push switch 704. When switch 704 is turned on, a locking groove 705 is provided inside the mounting base 3. The locking groove 705 communicates with the interior of the clearance cavity 606. A locking protrusion 706 is slidably connected inside the locking groove 705. A drive screw 707 is movably disposed inside the locking groove 705. One end of the drive screw 707 extends into the interior of the locking protrusion 706 and is threadedly connected to the locking protrusion 706. Thus, when switch 704 is turned on, the locking protrusion 706 will extend into the interior of the clearance cavity 606 under the action of the drive screw 707. Subsequently, the locking protrusion 706 will cooperate with the push rod 607. This design limits the position of the push rod 607. The left end of the sensing pipe 4 is connected to the indoor air, and the right end of the sensing pipe 4 is fixedly installed with a control valve housing 708. A blocking ball 709 is movably installed inside the control valve housing 708. A push spring 710 is fixedly connected to the right end of the blocking ball 709. In the initial state, the blocking ball 709 is in a blocking state of the control valve housing 708. One end of the push spring 710 is fixedly connected to the blocking ball 709, and the other end of the push spring 710 is fixedly connected to the inner wall of the control valve housing 708. The push spring 710 is always in a compressed state. This ensures that the gas inside the sensing pipe 4 can only flow from the left side to the right side of the control valve housing 708, achieving a unidirectional gas flow effect. An internal power supply 711 is installed inside the mounting base 3.Therefore, when a power outage occurs due to a fire indoors, the internal power supply 711 can continue to supply power to the electric motor 611, ensuring that the push rod 607 can retract into the interior of the clearance cavity 606 in a timely manner. The upper end of the connecting groove 605 is connected to the interior of the pneumatic cavity 701, and the lower end of the connecting groove 605 is connected to the interior of the control groove 601. The movable slider 703 and the methane detection block 602 are movably connected by the flexible connecting rod 604. The connection between the connecting groove 605 and the pneumatic cavity 701 is sealed. Thus, when the movable slider 703 moves upward along the pneumatic cavity 701, it can move the methane detection block 602 upward along the inner wall of the control groove 601 through cooperation with the flexible connecting rod 604.
[0043] Working principle:
[0044] After being awakened by alarm number 5, the elderly will quickly evacuate to a safe area. However, at this time, the concentration of gas in the room is still high, and the air is relatively dry, so a fire is very likely to occur.
[0045] When an open flame appears indoors, the indoor temperature will rise rapidly, and the temperature of the air entering the sensing pipe 4 will also rise rapidly. After the gas inside the sensing pipe 4 comes into contact with the heat-conducting block 702, the heat-conducting block 702 will conduct heat to the interior of the pneumatic cavity 701.
[0046] Since the pneumatic cavity 701 is filled with an appropriate amount of nitrogen, the temperature inside the pneumatic cavity 701 will rise, causing the volume of nitrogen to increase. Subsequently, the movable slider 703 will move upward along the inner wall of the pneumatic cavity 701 under the push of the gas. When the movable slider 703 moves upward, it will press the push switch 704. After the push switch 704 is pressed and turned on, it will drive the gear 608 to rotate in the opposite direction through the cooperation of the electric motor 611. After the gear 608 rotates in the opposite direction, it will cause the push rod 607 to move downward along the inner wall of the clearance cavity 606. During the downward movement of the push rod 607, the window will be closed.
[0047] When the movable slider 703 moves upward, it will cooperate with the flexible connecting rod 604 to make the methane detection block 602 move upward along the inner wall of the control groove 601, and finally retract the methane detection block 602 into the interior of the control groove 601, thereby avoiding the effect of the methane sensor inside the methane detection block 602 exploding due to excessive temperature inside the sensing pipe 4.
[0048] In addition, after the push rod 607 retracts into the clearance cavity 606, the locking protrusion 706 will extend into the clearance cavity 606 under the drive of the drive screw 707. After the locking protrusion 706 extends into the clearance cavity 606, it will limit the position of the push rod 607 inside the clearance cavity 606 through cooperation with the push rod 607.
[0049] Therefore, when personnel evacuate and an open flame occurs indoors due to excessive gas concentration, the system can automatically close the open windows and retract the methane detection block 602 during the window closing process. This not only prevents outside air from entering the room and causing the fire to intensify, but also prevents the methane detection block 602 from exploding due to excessive temperature. Example 3:
[0050] Please see Figures 1-11A smart fire-fighting window opener capable of preventing hand pinching includes a window frame 1, a window glass 2 rotatably connected to the upper end of the window frame 1, a mounting base 3 at the lower end of the window frame 1, a sensor pipe 4 at the lower end of the mounting base 3, alarms 5 on both sides of the mounting base 3, a gas safety mechanism 6 movably installed inside the mounting base 3, and an automatic fire-closing mechanism 7 at the lower end of the mounting base 3. The gas safety mechanism 6 includes a control groove 601, which is vertically located at the lower end of the mounting base 3. A methane detection block 602 is slidably connected inside the control groove 601, with its upper end located inside and slidably connected to the control groove 601, and its lower end extending into the sensor pipe. Inside channel 4, a reset spring 603 is fixedly connected to the upper end of the methane detection block 602. The lower end of the reset spring 603 is fixedly connected to the upper end of the methane detection block 602, and the upper end of the reset spring 603 is fixedly connected to the inner wall of the control groove 601.

The connecting groove 605 is connected to the inside of the control groove 601. Thus, in the initial state, the lower end of the methane detection block 602 will extend into the inside of the sensing channel 4 under its own weight and the action of the reset spring 603. When the flexible connecting rod 604... 4. When moving upward along the connecting groove 605, the methane detection block 602 will retract upward. The mounting base 3 has vertically formed clearance cavities 606 on both the left and right sides. The upper end of the clearance cavity 606 is open. A push rod 607 is slidably connected inside the clearance cavity 606. The upper end of the push rod 607 is fixedly connected to the lower end of the window glass 2, and the outer surface shape of the push rod 607 matches the outer surface shape of the drive gear 608.

A rectangular protrusion 613 is provided on the lower end of the push rod 607, so that when the drive gear 608 rotates, the push rod 607 can move along the clearance cavity 606. The inner wall moves upward or downward. When the push rod 607 moves upward, it pushes the window glass 2 outward; when the push rod 607 moves downward, it causes the window glass 2 to retract inward. A mounting groove 609 is horizontally opened on one side of the inner wall of the clearance cavity 606. An alarm switch 610 is slidably connected inside the mounting groove 609. The alarm switch 610 is electrically connected to a power source via a wire. An electric motor 611 is installed inside the mounting base 3. Thus, when the push rod 607 moves upward, the rectangular protrusion 613 presses against the alarm switch 610. When the alarm switch 610 is pressed and activated, the alarm 5 sounds. A methane sensor is installed inside the methane detection block 602. The flexible connecting rod 604 is made of a flexible and bendable material.Therefore, when methane gas appears inside the sensing pipe 4, the methane sensor will quickly detect its presence and, in conjunction with the electric motor 611, cause the drive gear 608 to rotate. The rotation of the drive gear 608 will cause the push rod 607 to move upwards.

Therefore, when the push switch 704 is turned on, the locking protrusion 706 extends into the clearance cavity 606 under the action of the drive screw 707. Subsequently, the locking protrusion 706 cooperates with the push rod 607, causing the position of the push rod 607 to be adjusted. The sensing pipe 4 is connected to the indoor air at its left end, and a control valve housing 708 is fixedly installed at its right end. A blocking ball 709 is movably installed inside the control valve housing 708, and a push spring 710 is fixedly connected to the right end of the blocking ball 709. Initially, the blocking ball 709 blocks the control valve housing 708. One end of the push spring 710 is fixedly connected to the blocking ball 709, and the other end is fixedly connected to the inner wall of the control valve housing 708. The push spring 710 is always in a compressed state. This ensures that the gas inside the sensing pipe 4 can only flow from the left side to the right side of the control valve housing 708, achieving a unidirectional gas flow effect. An internal power supply 711 is installed inside the mounting base 3. Therefore, when a power outage occurs due to a fire indoors, the internal power supply 711 can continue to supply power to the electric motor 611, ensuring that the push rod 607 can retract into the clearance cavity 606 in a timely manner. The upper end of the connecting groove 605 is connected to the inside of the pneumatic cavity 701, and the lower end of the connecting groove 605 is connected to the inside of the control groove 601. The movable slider 703 and the methane detection block 602 are movably connected by a flexible connecting rod 604. The connection between the connecting groove 605 and the pneumatic cavity 701 is sealed, so when the movable slider 703 moves upward along the pneumatic cavity 701...The methane detection block 602 can move upwards along the inner wall of the control groove 601 through cooperation with the flexible connecting rod 604.
[0051] Working principle:
[0052] In the initial state, the push rod 607 is located inside the avoidance cavity 606, the left end of the sensing pipe 4 is connected to the indoor environment, and the right end of the sensing pipe 4 is connected to the external environment.
[0053] When a gas leak occurs indoors, the air containing gas will enter the interior of the sensing pipe 4. Since the main component of the gas is methane, the gas will come into contact with the methane detection block 602 that extends into the sensing pipe 4 after entering the gas. The methane detection block 602 is equipped with a methane sensor. Therefore, when the gas comes into contact with the methane detection block 602, the electric motor 611 will start to work.
[0054] When the electric motor 611 starts working, it will cause the drive gear 608 to rotate. When the drive gear 608 rotates, it will cooperate with the push rod 607 to extend the push rod 607 outward. When the push rod 607 extends outward, it will push the window glass 2 outward, and then the window will be opened.
[0055] Additionally, as the push rod 607 moves upward along the clearance cavity 606, the rectangular protrusion 613 will come into contact with the alarm switch 610. When the alarm switch 610 is pressed, it will be turned on, and then the alarm 5 will sound an alarm to wake up people who are asleep.
[0056] After being awakened by alarm number 5, the elderly will quickly evacuate to a safe area. However, at this time, the concentration of gas in the room is still high, and the air is relatively dry, so a fire is very likely to occur.
[0057] When an open flame appears indoors, the indoor temperature will rise rapidly, and the temperature of the air entering the sensing pipe 4 will also rise rapidly. After the gas inside the sensing pipe 4 comes into contact with the heat-conducting block 702, the heat-conducting block 702 will conduct heat to the interior of the pneumatic cavity 701.
[0058] Since the pneumatic cavity 701 is filled with an appropriate amount of nitrogen, the temperature inside the pneumatic cavity 701 will rise, causing the volume of nitrogen to increase. Subsequently, the movable slider 703 will move upward along the inner wall of the pneumatic cavity 701 under the push of the gas. When the movable slider 703 moves upward, it will press the push switch 704. After the push switch 704 is pressed and turned on, it will drive the gear 608 to rotate in the opposite direction through the cooperation of the electric motor 611. After the gear 608 rotates in the opposite direction, it will cause the push rod 607 to move downward along the inner wall of the clearance cavity 606. During the downward movement of the push rod 607, the window will be closed.
[0059] When the movable slider 703 moves upward, it will cooperate with the flexible connecting rod 604 to make the methane detection block 602 move upward along the inner wall of the control groove 601, and finally retract the methane detection block 602 into the interior of the control groove 601, thereby avoiding the effect of the methane sensor inside the methane detection block 602 exploding due to excessive temperature inside the sensing pipe 4.
[0060] In addition, after the push rod 607 retracts into the clearance cavity 606, the locking protrusion 706 will extend into the clearance cavity 606 under the drive of the drive screw 707. After the locking protrusion 706 extends into the clearance cavity 606, it will limit the position of the push rod 607 inside the clearance cavity 606 through cooperation with the push rod 607.
[0061] This system enables timely window opening to reduce indoor gas concentration in the event of a gas leak at night, while simultaneously sounding a loud alarm to wake sleeping individuals. Furthermore, if an open flame appears indoors after evacuation, the system automatically closes the open windows and retracts the methane detection block 602 during the closing process. This prevents outside air from entering and causing the fire to intensify, and also prevents the methane detection block 602 from exploding due to excessive temperature.
[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
