[0065] As can be seen from the above, by setting the sensor component 10 to detect the working state of the gas stove and generate the first detection signal, the second detection signal and the third detection signal, when the first detection signal meets the first condition, the second detection signal meets the second condition, and the third detection signal meets the third condition, the controller 30 can promptly determine the abnormal working state of the gas stove, and promptly control the operation of the fire extinguishing component 20, so that the fire extinguishing component 20 can extinguish the fire in time, which not only effectively prevents the gas stove from causing a fire, plays a protective role, and improves the safety performance of the gas stove, but also uses the comparison and judgment of the three detection signals and conditions to ensure that the fire can be accurately identified, avoid misjudgment resulting in incorrect operation of the fire extinguishing component 20 or untimely operation of the fire extinguishing component, so as to further improve safety and user experience.

[0066] It should be noted that the gas stove includes a panel assembly 40, a burner 50 and a pot rack 60; the panel assembly 40 includes a panel, a bottom plate and a ring plate 430, the panel is provided with through holes, the through holes correspond to the ring plates 430 one by one, the ring plates 430 are arranged in the corresponding through holes, the bottom plate is connected to the bottom of the panel and forms an installation cavity; the burner 50 corresponds to the ring plates 430 one by one, the burner 50 is penetrated in the corresponding ring plates 430, and the ejector tube of the burner 50 is located in the installation cavity; the pot rack 60 corresponds to the burner 50 one by one, the pot rack 60 is placed on the ring plate 430 and is sleeved on the corresponding burner 50; in addition, as Figure 1 As shown, the number of the burners 50 may be two, and the two burners 50 are arranged side by side on the panel assembly 40 .

[0068] In some embodiments, the first detection signal is the real-time detected temperature of the panel assembly 40 , the second detection signal is the real-time detected concentration of the leaked fuel gas, and the third detection signal is the ignition state of the panel assembly 40 .

[0069] By detecting the temperature, gas concentration and ignition status of the gas stove respectively, the working status of the gas stove can be monitored from multiple dimensions and aspects.

[0075] If the first detection signal satisfies the first condition, the second detection signal does not satisfy the second condition, and the third detection signal does not satisfy the third condition, monitoring continues.

[0078] As can be seen from the above, by setting the sensor component 10 to detect the working state of the gas stove and generate the first detection signal, the second detection signal and the third detection signal, when the first detection signal meets the first condition, the second detection signal meets the second condition, and the third detection signal meets the third condition, the controller 30 can promptly determine the abnormal working state of the gas stove, and promptly control the operation of the fire extinguishing component 20, so that the fire extinguishing component 20 can extinguish the fire in time, which not only effectively prevents the gas stove from causing a fire, plays a protective role, and improves the safety performance of the gas stove, but also uses the comparison and judgment of the three detection signals and conditions to ensure that the fire can be accurately identified, avoid misjudgment resulting in incorrect operation of the fire extinguishing component 20 or untimely operation of the fire extinguishing component, so as to further improve safety and user experience.

[0079] It should be noted that the gas stove includes a panel assembly 40, a burner 50 and a pot rack 60; the panel assembly 40 includes a panel, a bottom plate and a ring plate 430, the panel is provided with through holes, the through holes correspond to the ring plates 430 one by one, the ring plates 430 are arranged in the corresponding through holes, the bottom plate is connected to the bottom of the panel and forms an installation cavity; the burner 50 corresponds to the ring plates 430 one by one, the burner 50 is penetrated in the corresponding ring plates 430, and the ejector tube of the burner 50 is located in the installation cavity; the pot rack 60 corresponds to the burner 50 one by one, the pot rack 60 is placed on the ring plate 430 and is sleeved on the corresponding burner 50; in addition, as Figure 1 As shown, the number of the burners 50 may be two, and the two burners 50 are arranged side by side on the panel assembly 40 .

[0080] It should also be noted that if Figure 1 , Figure 2 As shown, a fire extinguishing assembly 20 and a sensor assembly 10 are disposed outside each burner 50 . The fire extinguishing assembly 20 is disposed in the installation cavity. The sensor assembly 10 is located on the ring plate 430 , and the sensor assembly 10 is located in the pot rack 60 .

[0081] In some embodiments, the first detection signal is the real-time detected temperature of the panel assembly 40 , the second detection signal is the real-time detected concentration of the leaked fuel gas, and the third detection signal is the ignition state of the panel assembly 40 .

[0082] By detecting the temperature, gas concentration and ignition status of the gas stove respectively, the working status of the gas stove can be monitored from multiple dimensions and aspects. This can not only ensure the effective use of the fire extinguishing component and further improve the safety performance of the gas stove, but also avoid the accidental activation of the fire extinguishing component.

[0083] It should be noted that the ignition state includes a normal ignition state and an abnormal ignition state; the normal ignition state means that the burner head 50 of the gas stove ignites normally for cooking, and the fire of the burner head 50 will not burn to the fire extinguishing port 410; the abnormal ignition state means that the fire burns to the fire extinguishing port 410, and the fire sensor detects abnormal ignition.

[0085] It should be noted that the controller 30 pre-sets a preset temperature threshold, a preset concentration threshold, and a preset ignition threshold. The controller 30 compares the received first detection signal, the second detection signal, and the third detection signal with the above thresholds respectively. If the real-time detection temperature is greater than or equal to the preset temperature threshold, the real-time detection concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in an abnormal ignition state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire; for example, the preset temperature threshold is 100°C.

[0086] It should also be noted that if the first detection signal satisfies the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0087] If the first detection signal does not satisfy the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0088] If the first detection signal satisfies the first condition, the second detection signal does not satisfy the second condition, and the third detection signal does not satisfy the third condition, monitoring continues.

[0089] like Figure 2 As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing part 210, a nozzle 220, a button 230 and a driving part 240; the fire extinguishing part 210 is provided with a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing part 210; the button 230 is arranged at one end of the fire extinguishing part 210; the driving part 240 is electrically connected to the controller 30, and the driving part 240 is constructed to be able to press the button 230 so that the fire extinguishing agent is sprayed out through the nozzle 220.

[0090] The button 230 is pressed by the driving unit 240, thereby driving the fire extinguishing unit 210 to perform fire extinguishing work; when there is an abnormal working state, the controller 30 controls the driving unit 240 to press the button 230, and the fire extinguishing agent in the fire extinguishing unit 210 is sprayed out through the nozzle 220, thereby extinguishing the fire in time to avoid causing a fire.

[0091] like Figure 3As shown, in some embodiments, the fire extinguishing agent includes a gas fire extinguishing agent and a dry powder fire extinguishing agent, and the fire extinguishing unit 210 includes a shell 2101, a partition 2102, a piercing member 2105 and a pouring pipe 2106; the partition 2102 is arranged in the shell 2101 to separate the shell 2101 into a first storage area 2103 and a second storage area 2104, the gas fire extinguishing agent is located in the first storage area 2103, and the button 230 is arranged at one end of the first storage area 2103 away from the second storage area 2104, and the dry powder fire extinguishing agent is located in the second storage area 2104; the piercing member 2105 is arranged in the first storage area 2103 and one end is connected to the button 230; the pouring pipe 2106 is penetrated in the piercing member 2105, and the pouring pipe 2106 includes a first end and a second end, the first end is connected to the nozzle 220, and the second end passes through the partition 2102 and is connected to the second storage area 2104.

[0092] The shell 2101 is separated into a first storage area 2103 and a second storage area 2104 which are independent and unconnected by the partition 2102. The button 230 is pressed by the driving unit 240 so that the button 230 drives the piercing member 2105 to move toward the partition 2102. The piercing member 2105 pierces the partition 2102 so that the first storage area 2103 is connected to the second storage area 2104. Under the action of the pressure difference, the gas fire extinguishing agent quickly flows from the first storage area 2103 to the second storage area 2104. The gas fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the pouring pipe 2106. The gas fire extinguishing agent causes the dry powder fire extinguishing agent to form a flowable suspension state, which is directly sprayed out through the nozzle 220 to extinguish the gas stove.

[0093] It should be noted that gaseous fire extinguishing agents include but are not limited to high-pressure nitrogen.

[0094] It should also be noted that a first perforation through which a pouring pipe 2106 passes is provided on the partition 2102, and the pouring pipe 2106 is sealedly connected to the inner wall of the first perforation to prevent the gaseous fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring pipe 2106 and the first perforation when no fire extinguishing is needed. In addition, when no fire extinguishing is needed, there is a gap between the end of the piercing member 2105 close to the partition 2102 and the partition 2102.

[0095] It should also be noted that a second through-hole is provided on the button 230 for the nozzle 220 to pass through, and the nozzle 220 is inserted into the second through-hole and communicated with the first end of the pouring tube 2106; there is a distance between the button 230 and the first end of the pouring tube 2106 to avoid interference between the button 230 and the pouring tube 2106 after being pressed, thereby affecting the normal pressing of the button 230; in addition, the end of the pouring tube 2106 away from the nozzle 220 is deeply inserted into the fire extinguishing agent and is as close to the second end as possible, so that the gas fire extinguishing agent can enter the second storage area 2104 and be fully mixed with the dry powder fire extinguishing agent.

[0099] It should be noted that the gas stove includes a panel assembly 40, a burner 50 and a pot rack 60; the panel assembly 40 includes a panel, a bottom plate and a ring plate 430, the panel is provided with through holes, the through holes correspond to the ring plates 430 one by one, the ring plates 430 are arranged in the corresponding through holes, the bottom plate is connected to the bottom of the panel and forms an installation cavity; the burner 50 corresponds to the ring plates 430 one by one, the burner 50 is penetrated in the corresponding ring plates 430, and the ejector tube of the burner 50 is located in the installation cavity; the pot rack 60 corresponds to the burner 50 one by one, the pot rack 60 is placed on the ring plate 430 and is sleeved on the corresponding burner 50; in addition, as Figure 1 As shown, the number of the burners 50 may be two, and the two burners 50 are arranged side by side on the panel assembly 40 .

[0100] It should also be noted that if Figure 1 , Figure 2As shown, a fire extinguishing assembly 20 and a sensor assembly 10 are disposed outside each burner 50 . The fire extinguishing assembly 20 is disposed in the installation cavity. The sensor assembly 10 is located on the ring plate 430 , and the sensor assembly 10 is located in the pot rack 60 .

[0101] In some embodiments, the first detection signal is the real-time detected temperature of the panel assembly 40 , the second detection signal is the real-time detected concentration of the leaked fuel gas, and the third detection signal is the ignition state of the panel assembly 40 .

[0102] By detecting the temperature, gas concentration and ignition status of the gas stove respectively, the working status of the gas stove can be monitored from multiple dimensions and aspects. This can not only ensure the effective use of the fire extinguishing component and further improve the safety performance of the gas stove, but also avoid the accidental activation of the fire extinguishing component.

[0103] It should be noted that the ignition state includes a normal ignition state and an abnormal ignition state; the normal ignition state means that the burner head 50 of the gas stove ignites normally for cooking, and the fire of the burner head 50 will not burn to the fire extinguishing port 410; the abnormal ignition state means that the fire burns to the fire extinguishing port 410, and the fire sensor detects abnormal ignition.

[0104] In some embodiments, the first condition is that the real-time detected temperature is greater than or equal to a preset temperature threshold; the second condition is that the real-time detected concentration is greater than or equal to a preset concentration threshold; and the third condition is that the panel assembly is in an abnormal fire state.

[0105] It should be noted that the controller 30 pre-sets a preset temperature threshold and a preset concentration threshold. The controller 30 compares the received first detection signal and the second detection signal with the above thresholds respectively. If the real-time detected temperature is greater than or equal to the preset temperature threshold, the real-time detected concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in an abnormal fire state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire; for example, the preset temperature threshold is 100°C.

[0106] It should also be noted that if the first detection signal satisfies the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0107] If the first detection signal does not satisfy the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0108] If the first detection signal satisfies the first condition, the second detection signal does not satisfy the second condition, and the third detection signal does not satisfy the third condition, monitoring continues.

[0109] like Figure 2As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing part 210, a nozzle 220, a button 230 and a driving part 240; the fire extinguishing part 210 is provided with a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing part 210; the button 230 is arranged at one end of the fire extinguishing part 210; the driving part 240 is electrically connected to the controller 30, and the driving part 240 is constructed to be able to press the button 230 so that the fire extinguishing agent is sprayed out through the nozzle 220.

[0110] The button 230 is pressed by the driving unit 240, thereby driving the fire extinguishing unit 210 to perform fire extinguishing work; when there is an abnormal working state, the controller 30 controls the driving unit 240 to press the button 230, and the fire extinguishing agent in the fire extinguishing unit 210 is sprayed out through the nozzle 220, thereby extinguishing the fire in time to avoid causing a fire.

[0111] like Figure 3 As shown, in some embodiments, the fire extinguishing agent includes a gas fire extinguishing agent and a dry powder fire extinguishing agent, and the fire extinguishing unit 210 includes a shell 2101, a partition 2102, a piercing member 2105 and a pouring pipe 2106; the partition 2102 is arranged in the shell 2101 to separate the shell 2101 into a first storage area 2103 and a second storage area 2104, the gas fire extinguishing agent is located in the first storage area 2103, and the button 230 is arranged at one end of the first storage area 2103 away from the second storage area 2104, and the dry powder fire extinguishing agent is located in the second storage area 2104; the piercing member 2105 is arranged in the first storage area 2103 and one end is connected to the button 230; the pouring pipe 2106 is penetrated in the piercing member 2105, and the pouring pipe 2106 includes a first end and a second end, the first end is connected to the nozzle 220, and the second end passes through the partition 2102 and is connected to the second storage area 2104.

[0112] The shell 2101 is separated into a first storage area 2103 and a second storage area 2104 which are independent and unconnected by the partition 2102. The button 230 is pressed by the driving unit 240 so that the button 230 drives the piercing member 2105 to move toward the partition 2102. The piercing member 2105 pierces the partition 2102 so that the first storage area 2103 is connected to the second storage area 2104. Under the action of the pressure difference, the gas fire extinguishing agent quickly flows from the first storage area 2103 to the second storage area 2104. The gas fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the pouring pipe 2106. The gas fire extinguishing agent causes the dry powder fire extinguishing agent to form a flowable suspension state, which is directly sprayed out through the nozzle 220 to extinguish the gas stove.

[0113] It should be noted that gaseous fire extinguishing agents include but are not limited to high-pressure nitrogen.

[0114] It should also be noted that a first perforation through which a pouring pipe 2106 passes is provided on the partition 2102, and the pouring pipe 2106 is sealedly connected to the inner wall of the first perforation to prevent the gaseous fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring pipe 2106 and the first perforation when no fire extinguishing is needed. In addition, when no fire extinguishing is needed, there is a gap between the end of the piercing member 2105 close to the partition 2102 and the partition 2102.

[0115] It should also be noted that a second through-hole is provided on the button 230 for the nozzle 220 to pass through, and the nozzle 220 is inserted into the second through-hole and communicated with the first end of the pouring tube 2106; there is a distance between the button 230 and the first end of the pouring tube 2106 to avoid interference between the button 230 and the pouring tube 2106 after being pressed, thereby affecting the normal pressing of the button 230; in addition, the end of the pouring tube 2106 away from the nozzle 220 is deeply inserted into the fire extinguishing agent and is as close to the second end as possible, so that the gas fire extinguishing agent can enter the second storage area 2104 and be fully mixed with the dry powder fire extinguishing agent.

[0116] like Figure 2 As shown, in some embodiments, the driving unit 240 includes a shell 2401, an airbag 2402 and an inflatable member 2403; the shell 2401 is provided with a socket for inserting the button 230; the airbag 2402 is arranged in the shell 2401; the inflatable member 2403 is arranged on the panel assembly 40 and is electrically connected to the controller 30, and the inflatable member 2403 responds to the inflation command issued by the controller 30 and communicates with the airbag 2402, so that the airbag 2402 is inflated and presses the button 230.

[0117] The airbag 2402 is inflated by the inflatable piece 2403 so that the volume of the airbag 2402 gradually increases. The inflated airbag 2402 presses the button 230 , and the button 230 drives the piercing piece 2105 to move, so that the piercing piece 2105 pierces the partition 2102 .

[0118] It should be noted that the inflatable component 2403 includes but is not limited to an air pump, and the controller 30 controls the opening and closing of the inflatable component 2403, so that the inflatable component 2403 can automatically inflate the airbag 2402, causing the airbag 2402 to expand and bulge; in addition, the inflatable component 2403 can be connected to the airbag 2402 through an inflatable tube, and a valve is provided on the inflatable tube, and the valve is electrically connected to the controller 30; when the fire extinguishing unit 210 completes the fire extinguishing, the controller 30 controls the inflatable component 2403 to close, and the inflatable component 2403 stops inflating the airbag 2402. The controller 30 can also control the valve to open, the leakage volume of the airbag 2402 becomes smaller, and the button 230 returns to its original state after losing the pressing force.

[0119] It should also be noted that, in some embodiments, the inflatable member 2403 can be replaced by a driving member, which includes but is not limited to an electric push rod. The driving member is disposed in the housing 2401 and is electrically connected to the controller 30. The telescopic rod of the driving member is connected to the button 230. The driving member extends the telescopic rod in response to the inflation command issued by the controller 30 to press the button 230.

[0122] As can be seen from the above, by setting the sensor component 10 to detect the working state of the gas stove and generate the first detection signal, the second detection signal and the third detection signal, when the first detection signal meets the first condition, the second detection signal meets the second condition, and the third detection signal meets the third condition, the controller 30 can promptly determine the abnormal working state of the gas stove, and promptly control the operation of the fire extinguishing component 20, so that the fire extinguishing component 20 can extinguish the fire in time, which not only effectively prevents the gas stove from causing a fire, plays a protective role, and improves the safety performance of the gas stove, but also uses the comparison and judgment of the three detection signals and conditions to ensure that the fire can be accurately identified, avoid misjudgment resulting in incorrect operation of the fire extinguishing component 20 or untimely operation of the fire extinguishing component, so as to further improve safety and user experience.

[0123] It should be noted that the gas stove includes a panel assembly 40, a burner 50 and a pot rack 60; the panel assembly 40 includes a panel, a bottom plate and a ring plate 430, the panel is provided with through holes, the through holes correspond to the ring plates 430 one by one, the ring plates 430 are arranged in the corresponding through holes, the bottom plate is connected to the bottom of the panel and forms an installation cavity; the burner 50 corresponds to the ring plates 430 one by one, the burner 50 is penetrated in the corresponding ring plates 430, and the ejector tube of the burner 50 is located in the installation cavity; the pot rack 60 corresponds to the burner 50 one by one, the pot rack 60 is placed on the ring plate 430 and is sleeved on the corresponding burner 50; in addition, as Figure 1As shown, the number of the burners 50 may be two, and the two burners 50 are arranged side by side on the panel assembly 40 .

[0126] By detecting the temperature, gas concentration and ignition status of the gas stove respectively, the working status of the gas stove can be monitored from multiple dimensions and aspects. This can not only ensure the effective use of the fire extinguishing component and further improve the safety performance of the gas stove, but also avoid the accidental activation of the fire extinguishing component.

[0127] It should be noted that the ignition state includes a normal ignition state and an abnormal ignition state; the normal ignition state means that the burner head 50 of the gas stove ignites normally for cooking, and the fire of the burner head 50 will not burn to the fire extinguishing port 410; the abnormal ignition state means that the fire burns to the fire extinguishing port 410, and the fire sensor detects abnormal ignition.

[0129] It should be noted that the controller 30 pre-sets a preset temperature threshold and a preset concentration threshold. The controller 30 compares the received first detection signal and the second detection signal with the above thresholds respectively. If the real-time detected temperature is greater than or equal to the preset temperature threshold, the real-time detected concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in an abnormal fire state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire; for example, the preset temperature threshold is 100°C.

[0130] It should also be noted that if the first detection signal satisfies the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0131] If the first detection signal does not satisfy the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0132] If the first detection signal satisfies the first condition, the second detection signal does not satisfy the second condition, and the third detection signal does not satisfy the third condition, monitoring continues.

[0133] like Figure 2 As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing part 210, a nozzle 220, a button 230 and a driving part 240; the fire extinguishing part 210 is provided with a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing part 210; the button 230 is arranged at one end of the fire extinguishing part 210; the driving part 240 is electrically connected to the controller 30, and the driving part 240 is constructed to be able to press the button 230 so that the fire extinguishing agent is sprayed out through the nozzle 220.

[0134] The button 230 is pressed by the driving unit 240, thereby driving the fire extinguishing unit 210 to perform fire extinguishing work; when there is an abnormal working state, the controller 30 controls the driving unit 240 to press the button 230, and the fire extinguishing agent in the fire extinguishing unit 210 is sprayed out through the nozzle 220, thereby extinguishing the fire in time to avoid causing a fire.

[0135] like Figure 3 As shown, in some embodiments, the fire extinguishing agent includes a gas fire extinguishing agent and a dry powder fire extinguishing agent, and the fire extinguishing unit 210 includes a shell 2101, a partition 2102, a piercing member 2105 and a pouring pipe 2106; the partition 2102 is arranged in the shell 2101 to separate the shell 2101 into a first storage area 2103 and a second storage area 2104, the gas fire extinguishing agent is located in the first storage area 2103, and the button 230 is arranged at one end of the first storage area 2103 away from the second storage area 2104, and the dry powder fire extinguishing agent is located in the second storage area 2104; the piercing member 2105 is arranged in the first storage area 2103 and one end is connected to the button 230; the pouring pipe 2106 is penetrated in the piercing member 2105, and the pouring pipe 2106 includes a first end and a second end, the first end is connected to the nozzle 220, and the second end passes through the partition 2102 and is connected to the second storage area 2104.

[0136] The shell 2101 is separated into a first storage area 2103 and a second storage area 2104 which are independent and unconnected by the partition 2102. The button 230 is pressed by the driving unit 240 so that the button 230 drives the piercing member 2105 to move toward the partition 2102. The piercing member 2105 pierces the partition 2102 so that the first storage area 2103 is connected to the second storage area 2104. Under the action of the pressure difference, the gas fire extinguishing agent quickly flows from the first storage area 2103 to the second storage area 2104. The gas fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the pouring pipe 2106. The gas fire extinguishing agent causes the dry powder fire extinguishing agent to form a flowable suspension state, which is directly sprayed out through the nozzle 220 to extinguish the gas stove.

[0137] It should be noted that gaseous fire extinguishing agents include but are not limited to high-pressure nitrogen.

[0138] It should also be noted that a first perforation through which a pouring pipe 2106 passes is provided on the partition 2102, and the pouring pipe 2106 is sealedly connected to the inner wall of the first perforation to prevent the gaseous fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring pipe 2106 and the first perforation when no fire extinguishing is needed. In addition, when no fire extinguishing is needed, there is a gap between the end of the piercing member 2105 close to the partition 2102 and the partition 2102.

[0139] It should also be noted that a second through-hole is provided on the button 230 for the nozzle 220 to pass through, and the nozzle 220 is inserted into the second through-hole and communicated with the first end of the pouring tube 2106; there is a distance between the button 230 and the first end of the pouring tube 2106 to avoid interference between the button 230 and the pouring tube 2106 after being pressed, thereby affecting the normal pressing of the button 230; in addition, the end of the pouring tube 2106 away from the nozzle 220 is deeply inserted into the fire extinguishing agent and is as close to the second end as possible, so that the gas fire extinguishing agent can enter the second storage area 2104 and be fully mixed with the dry powder fire extinguishing agent.

[0140] like Figure 2 As shown, in some embodiments, the driving unit 240 includes a shell 2401, an airbag 2402 and an inflatable member 2403; the shell 2401 is provided with a socket for inserting the button 230; the airbag 2402 is arranged in the shell 2401; the inflatable member 2403 is arranged on the panel assembly 40 and is electrically connected to the controller 30, and the inflatable member 2403 responds to the inflation command issued by the controller 30 and communicates with the airbag 2402, so that the airbag 2402 is inflated and presses the button 230.

[0141] The airbag 2402 is inflated by the inflatable piece 2403 so that the volume of the airbag 2402 gradually increases. The inflated airbag 2402 presses the button 230 , and the button 230 drives the piercing piece 2105 to move, so that the piercing piece 2105 pierces the partition 2102 .

[0142] It should be noted that the inflatable component 2403 includes but is not limited to an air pump, and the controller 30 controls the opening and closing of the inflatable component 2403, so that the inflatable component 2403 can automatically inflate the airbag 2402, causing the airbag 2402 to expand and bulge; in addition, the inflatable component 2403 can be connected to the airbag 2402 through an inflatable tube, and a valve is provided on the inflatable tube, and the valve is electrically connected to the controller 30; when the fire extinguishing unit 210 completes the fire extinguishing, the controller 30 controls the inflatable component 2403 to close, and the inflatable component 2403 stops inflating the airbag 2402. The controller 30 can also control the valve to open, the leakage volume of the airbag 2402 becomes smaller, and the button 230 returns to its original state after losing the pressing force.

[0143] It should also be noted that, in some embodiments, the inflatable member 2403 can be replaced by a driving member, which includes but is not limited to an electric push rod. The driving member is disposed in the housing 2401 and is electrically connected to the controller 30. The telescopic rod of the driving member is connected to the button 230. The driving member extends the telescopic rod in response to the inflation command issued by the controller 30 to press the button 230.

[0145] By setting the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove to be 6-11 cm, the fire extinguishing effect is ensured while the nozzle 220 is protected. On the one hand, the distance between the fire extinguishing port 410 and the burner head 50 is prevented from being too small, so that the fire sensor in the fire extinguishing port 410 can avoid erroneously detecting a normal fire, and at the same time, the flame of the burner head 50 when the gas stove is normally ignited can be prevented from damaging the nozzle 220; on the other hand, the distance between the fire extinguishing port 410 and the burner head 50 is prevented from being too large, so that when the gas stove is abnormally ignited, the fire extinguishing agent sprayed from the nozzle 220 cannot ensure the fire extinguishing effect.

[0146] It should be noted that the fire extinguishing port 410 is disposed on the ring plate 430 .

[0147] It should also be noted that the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove is 6-11 cm. Preferably, the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove is 10 cm.

[0153] In some embodiments, the first detection signal is the real-time detected temperature of the panel assembly 40 , the second detection signal is the real-time detected concentration of the leaked fuel gas, and the third detection signal is the ignition state of the panel assembly 40 .

[0154] By detecting the temperature, gas concentration and ignition status of the gas stove respectively, the working status of the gas stove can be monitored from multiple dimensions and aspects. This can not only ensure the effective use of the fire extinguishing component and further improve the safety performance of the gas stove, but also avoid the accidental activation of the fire extinguishing component.

[0155] It should be noted that the ignition state includes a normal ignition state and an abnormal ignition state; the normal ignition state means that the burner head 50 of the gas stove ignites normally for cooking, and the fire of the burner head 50 will not burn to the fire extinguishing port 410; the abnormal ignition state means that the fire burns to the fire extinguishing port 410, and the fire sensor detects abnormal ignition.

If the real-time detected temperature is greater than or equal to the preset temperature threshold, the real-time detected concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in an abnormal fire state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire; for example, the preset temperature threshold is 100°C.

[0158] It should also be noted that if the first detection signal satisfies the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0159] If the first detection signal does not satisfy the first condition, the second detection signal satisfies the second condition, and the third detection signal does not satisfy the third condition, the controller notifies the user;

[0160] If the first detection signal satisfies the first condition, the second detection signal does not satisfy the second condition, and the third detection signal does not satisfy the third condition, monitoring continues.

[0161] like Figure 2 As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing part 210, a nozzle 220, a button 230 and a driving part 240; the fire extinguishing part 210 is provided with a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing part 210; the button 230 is arranged at one end of the fire extinguishing part 210; the driving part 240 is electrically connected to the controller 30, and the driving part 240 is constructed to be able to press the button 230 so that the fire extinguishing agent is sprayed out through the nozzle 220.

[0162] The button 230 is pressed by the driving unit 240, thereby driving the fire extinguishing unit 210 to perform fire extinguishing work; when there is an abnormal working state, the controller 30 controls the driving unit 240 to press the button 230, and the fire extinguishing agent in the fire extinguishing unit 210 is sprayed out through the nozzle 220, thereby extinguishing the fire in time to avoid causing a fire.

[0163] like Figure 3As shown, in some embodiments, the fire extinguishing agent includes a gas fire extinguishing agent and a dry powder fire extinguishing agent, and the fire extinguishing unit 210 includes a shell 2101, a partition 2102, a piercing member 2105 and a pouring pipe 2106; the partition 2102 is arranged in the shell 2101 to separate the shell 2101 into a first storage area 2103 and a second storage area 2104, the gas fire extinguishing agent is located in the first storage area 2103, and the button 230 is arranged at one end of the first storage area 2103 away from the second storage area 2104, and the dry powder fire extinguishing agent is located in the second storage area 2104; the piercing member 2105 is arranged in the first storage area 2103 and one end is connected to the button 230; the pouring pipe 2106 is penetrated in the piercing member 2105, and the pouring pipe 2106 includes a first end and a second end, the first end is connected to the nozzle 220, and the second end passes through the partition 2102 and is connected to the second storage area 2104.

[0164] The shell 2101 is separated into a first storage area 2103 and a second storage area 2104 which are independent and unconnected by the partition 2102. The button 230 is pressed by the driving unit 240 so that the button 230 drives the piercing member 2105 to move toward the partition 2102. The piercing member 2105 pierces the partition 2102 so that the first storage area 2103 is connected to the second storage area 2104. Under the action of the pressure difference, the gas fire extinguishing agent quickly flows from the first storage area 2103 to the second storage area 2104. The gas fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the pouring pipe 2106. The gas fire extinguishing agent causes the dry powder fire extinguishing agent to form a flowable suspension state, which is directly sprayed out through the nozzle 220 to extinguish the gas stove.

[0165] It should be noted that gaseous fire extinguishing agents include but are not limited to high-pressure nitrogen.

[0166] It should also be noted that a first perforation through which a pouring pipe 2106 passes is provided on the partition 2102, and the pouring pipe 2106 is sealedly connected to the inner wall of the first perforation to prevent the gaseous fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring pipe 2106 and the first perforation when no fire extinguishing is needed. In addition, when no fire extinguishing is needed, there is a gap between the end of the piercing member 2105 close to the partition 2102 and the partition 2102.

[0167] It should also be noted that a second through-hole is provided on the button 230 for the nozzle 220 to pass through, and the nozzle 220 is inserted into the second through-hole and communicated with the first end of the pouring tube 2106; there is a distance between the button 230 and the first end of the pouring tube 2106 to avoid interference between the button 230 and the pouring tube 2106 after being pressed, thereby affecting the normal pressing of the button 230; in addition, the end of the pouring tube 2106 away from the nozzle 220 is deeply inserted into the fire extinguishing agent and is as close to the second end as possible, so that the gas fire extinguishing agent can enter the second storage area 2104 and be fully mixed with the dry powder fire extinguishing agent.

[0168] like Figure 2 As shown, in some embodiments, the driving unit 240 includes a shell 2401, an airbag 2402 and an inflatable member 2403; the shell 2401 is provided with a socket for inserting the button 230; the airbag 2402 is arranged in the shell 2401; the inflatable member 2403 is arranged on the panel assembly 40 and is electrically connected to the controller 30, and the inflatable member 2403 responds to the inflation command issued by the controller 30 and communicates with the airbag 2402, so that the airbag 2402 is inflated and presses the button 230.

[0169] The airbag 2402 is inflated by the inflatable piece 2403 so that the volume of the airbag 2402 gradually increases. The inflated airbag 2402 presses the button 230 , and the button 230 drives the piercing piece 2105 to move, so that the piercing piece 2105 pierces the partition 2102 .

[0170] It should be noted that the inflatable component 2403 includes but is not limited to an air pump, and the controller 30 controls the opening and closing of the inflatable component 2403, so that the inflatable component 2403 can automatically inflate the airbag 2402, causing the airbag 2402 to expand and bulge; in addition, the inflatable component 2403 can be connected to the airbag 2402 through an inflatable tube, and a valve is provided on the inflatable tube, and the valve is electrically connected to the controller 30; when the fire extinguishing unit 210 completes the fire extinguishing, the controller 30 controls the inflatable component 2403 to close, and the inflatable component 2403 stops inflating the airbag 2402. The controller 30 can also control the valve to open, the leakage volume of the airbag 2402 becomes smaller, and the button 230 returns to its original state after losing the pressing force.

[0171] It should also be noted that, in some embodiments, the inflatable member 2403 can be replaced by a driving member, which includes but is not limited to an electric push rod. The driving member is disposed in the housing 2401 and is electrically connected to the controller 30. The telescopic rod of the driving member is connected to the button 230. The driving member extends the telescopic rod in response to the inflation command issued by the controller 30 to press the button 230.

[0172] like Figure 1 , Figure 2 As shown, in some embodiments, a fire extinguishing port 410 is provided on the panel assembly 40, and the nozzle 220 is disposed in the fire extinguishing port 410, wherein the distance between the fire extinguishing port 410 and the burner 50 of the gas stove is 6-11 cm.

[0173] By setting the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove to be 6-11 cm, the fire extinguishing effect is ensured while the nozzle 220 is protected. On the one hand, the distance between the fire extinguishing port 410 and the burner head 50 is prevented from being too small, so that the fire sensor in the fire extinguishing port 410 can avoid erroneously detecting a normal fire, and at the same time, the flame of the burner head 50 when the gas stove is normally ignited can be prevented from damaging the nozzle 220; on the other hand, the distance between the fire extinguishing port 410 and the burner head 50 is prevented from being too large, so that when the gas stove is abnormally ignited, the fire extinguishing agent sprayed from the nozzle 220 cannot ensure the fire extinguishing effect.

[0174] It should be noted that the fire extinguishing port 410 is disposed on the ring plate 430 .

[0175] It should also be noted that the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove is 6-11 cm. Preferably, the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove is 10 cm.

[0176] like Figure 1 , Figure 2 As shown, in some embodiments, the sensing assembly includes a temperature sensor 110, an odor sensor 120 and a fire sensor; the temperature sensor 110 is disposed on the panel assembly 40 and is electrically connected to the controller 30, and the temperature sensor 110 is configured to detect the temperature of the panel assembly 40 and generate a corresponding first detection signal; the odor sensor 120 is disposed on the panel assembly 40 and is electrically connected to the controller 30, and the odor sensor 120 is configured to detect odor and generate a corresponding second detection signal; the fire sensor is disposed in the fire extinguishing port 410 and is electrically connected to the controller 30, and the fire sensor is configured to detect a fire state and generate a corresponding third detection signal.

[0177] The temperature of the panel assembly 40 is detected by the temperature sensor 110, the odor sensor 120 detects the concentration of the fuel gas, and the fire sensor detects the ignition state, thereby achieving real-time detection of the working state of the gas stove. The controller 30 controls the fire extinguishing assembly 20 to perform fire extinguishing work through the first detection signal, the second detection signal and the third detection signal.

[0178] In some embodiments, the fire sensor may be a silk-based ionic hydrogel (SIH) fiber that can sense fire.

[0179] In some embodiments, the distance between the temperature sensor 110 and / or the odor sensor 120 and the burner head 50 of the gas stove is 5-7 cm.

[0180] By setting the distance between the temperature sensor 110 and / or the odor sensor 120 and the burner head 50 to be 5-7 cm, the sensor can be protected while ensuring accurate detection. On the one hand, it can prevent the distance between the sensor and the burner head 50 from being too small, so that the flame of the burner head 50 when the gas stove is normally ignited can damage the nozzle 220; on the other hand, it can also prevent the distance between the sensor and the burner head 50 from being too large, so that the sensor can detect the temperature and odor inaccurately.

[0181] It should be noted that, preferably, the distance between the temperature sensor 110 and / or the odor sensor 120 and the burner head 50 of the gas stove is 6 cm.

[0182] In some embodiments, the gas stove protection structure also includes a gas leakage detector and an alarm; the gas leakage detector is arranged on the panel assembly 40 and is electrically connected to the controller 30; the alarm is arranged on the panel assembly 40 and is electrically connected to the controller 30.

[0183] Gas leaks can be detected by a gas leak detector, and an alarm can be set to promptly alert the user when the gas stove is in an abnormal working state.

[0184] It should be noted that if the real-time detected temperature is greater than or equal to the preset temperature threshold, the real-time detected concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in a normal ignition state, the controller 30 controls the alarm to notify the user; if the real-time detected temperature is less than the preset temperature threshold, the real-time detected concentration is greater than or equal to the preset concentration threshold, and the panel assembly 40 is in a normal ignition state, the controller 30 controls the alarm to notify the user; if the real-time detected temperature is greater than or equal to the preset temperature threshold, the real-time detected concentration is less than the preset concentration threshold, and the panel assembly 40 is in a normal ignition state, the working state of the gas stove continues to be monitored.

[0185] It should also be noted that the user's mobile phone can communicate with the controller 30, including but not limited to communication via Bluetooth and wireless network, so that the user can obtain the working status of the gas stove in real time and know the abnormal situation of the gas stove in time.
