[0070] It should be noted that the gas stove comprises the panel assembly 40, a burner 50, and a pot rack 60; the panel assembly 40 comprises 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, and the bottom plate is connected with the bottom of the panel and forms a mounting cavity; the burner 50 corresponds to the ring plate 430 one by one, the burner 50 is arranged in the corresponding ring plate 430, and the injection pipe of the burner 50 is located in the mounting 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 outside the corresponding burner 50; in addition, as shown in the figure, Figure 1 As shown in the figure, the number of the burners 50 can be two, and the two burners 50 are arranged side by side on the panel assembly 40.

[0071] It should be further noted that, as shown in the figure, Figure 1 , Figure 2 As shown in the figure, the extinguishing assembly 20 and the sensor assembly 10 are arranged outside each burner 50, the extinguishing assembly 20 is arranged in the mounting cavity, the sensor assembly 10 is located on the ring plate 430, and the sensor assembly 10 is located in the pot rack 60.

[0072] In some embodiments, the first detection signal is a real-time detection temperature of the panel assembly 40, the second detection signal is a real-time detection concentration of the leaked gas, and the third detection signal is a fire state of the panel assembly 40.

[0073] By detecting the temperature of the gas stove, the concentration of the gas, and the fire state, respectively, the working state of the gas stove is monitored from multiple dimensions and aspects, which not only ensures the effective use of the fire extinguishing assembly and further improves the safety performance of the gas stove, but also avoids the misstart of the fire extinguishing assembly.

[0074] It should be noted that the fire state includes a normal fire state and an abnormal fire state; the normal fire state is that the burner 50 of the gas stove is normally fired for cooking, and the fire of the burner 50 does not burn to the fire extinguishing port 410; the abnormal fire state is that the fire burns to the fire extinguishing port 410, and the fire burn sensor detects abnormal fire.

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 fire state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire; for example, the preset temperature threshold is 100℃.

[0077] It should also be noted that if the first detection signal meets the first condition, the second detection signal meets the second condition, and the third detection signal does not meet the third condition, the controller notifies the user;

[0078] If the first detection signal does not meet the first condition, the second detection signal meets the second condition, and the third detection signal does not meet the third condition, the controller notifies the user;

[0079] If the first detection signal meets the first condition, the second detection signal does not meet the second condition, and the third detection signal does not meet the third condition, the monitoring is continued.

[0080] For example, Figure 2As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing section 210, a nozzle 220, a button 230, and a drive section 240; the fire extinguishing section 210 contains a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing section 210; the button 230 is located at one end of the fire extinguishing section 210; the drive section 240 is electrically connected to the controller 30, and the drive section 240 is configured to press the button 230 to cause the fire extinguishing agent to be sprayed out through the nozzle 220.

[0081] Pressing button 230 via drive unit 240 activates fire extinguishing unit 210 for fire extinguishing operations. In case of abnormal operation, controller 30 controls drive unit 240 to press button 230, and fire extinguishing agent in fire extinguishing unit 210 is sprayed out through nozzle 220 to extinguish the fire in time and prevent it from causing a fire.

[0082] like Figure 3 As shown, in some embodiments, the extinguishing agent includes a gaseous extinguishing agent and a dry powder extinguishing agent. The extinguishing unit 210 includes a housing 2101, a partition 2102, a puncture member 2105, and a drain pipe 2106. The partition 2102 is disposed inside the housing 2101 to divide the housing 2101 into a first storage area 2103 and a second storage area 2104. The gaseous extinguishing agent is located in the first storage area 2103, and the button 230 is located at the end of the first storage area 2103 away from the second storage area 2104. The dry powder extinguishing agent is located in the second storage area 2104. The puncture member 2105 is disposed inside the first storage area 2103, and one end is connected to the button 230. The drain pipe 2106 passes through the puncture member 2105 and 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.

[0083] The housing 2101 is divided into two independent and non-communicating storage areas, a first storage area 2103 and a second storage area 2104, by a partition 2102. Pressing the button 230 with the drive unit 240 causes the button 230 to move the piercing member 2105 toward the partition 2102. The piercing member 2105 pierces the partition 2102, making the first storage area 2103 and the second storage area 2104 connected. Under the action of pressure difference, the gaseous fire extinguishing agent flows rapidly from the first storage area 2103 to the second storage area 2104. The gaseous fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the liquid discharge pipe 2106. The gaseous 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 fire on the gas stove.

[0084] It should be noted that gaseous fire extinguishing agents include, but are not limited to, high-pressure nitrogen.

[0085] It is also to be noted that the partition 2102 is provided with a first perforation through which the pouring tube 2106 penetrates, and the pouring tube 2106 is in sealing connection with the inner wall of the first perforation, so as to avoid the gas fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring tube 2106 and the first perforation when the fire extinguishing is not needed. In addition, the piercing member 2105 has a spacing between the end close to the partition 2102 and the partition 2102 when the fire extinguishing is not needed.

[0086] It is also to be noted that the button 230 is provided with a second perforation through which the spray pipe 220 penetrates, and the spray pipe 220 penetrates into the second perforation and is in communication with the first end of the pouring tube 2106; the button 230 and the first end of the pouring tube 2106 have a spacing therebetween, so as to avoid the interference between the button 230 and the pouring tube 2106 after the button 230 is pressed, and affect the normal pressing of the button 230; in addition, the end of the pouring tube 2106 far away from the spray pipe 220 is deeply inserted into the fire extinguishing agent, and is most likely close to the second end, so that the gas fire extinguishing agent entering the second storage area 2104 can be fully mixed with the dry powder fire extinguishing agent.

[0111] Embodiment five

[0112] As Figure 1 , Figure 2As shown, the gas stove protection structure comprises a sensor assembly 10, an extinguishing assembly 20, and a controller 30; the sensor assembly 10 is arranged on a panel assembly 40 of the gas stove, and the sensor assembly 10 is configured to detect the working state of the gas stove and generate corresponding first, second, and third detection signals; the extinguishing assembly 20 is arranged on the panel assembly 40; the controller 30 is arranged on the panel assembly 40, and the controller 30 is electrically connected with the sensor assembly 10 and the extinguishing assembly 20, and the controller 30 is configured to receive the first, second, and third detection signals and control the extinguishing assembly 20 to work 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.

[0113] As can be seen from the above, by arranging the sensor assembly 10 to detect the working state of the gas stove and generate the first, second, and third detection signals, the controller 30 can timely determine the abnormal working state of the gas stove 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, and timely control the extinguishing assembly 20 to work, so that the extinguishing assembly 20 can timely extinguish the fire, not only effectively avoiding the fire caused by the gas stove and playing a protection role, but also improving the safety performance of the gas stove, and using the comparison of the three detection signals and conditions to ensure that the fire can be accurately identified and misjudgment can be avoided to cause the extinguishing assembly 20 to malfunction or cause the extinguishing assembly to operate not timely, so as to further improve the safety and user experience.

[0114] It should be noted that the gas stove comprises the panel assembly 40, a burner 50, and a pot rack 60; the panel assembly 40 comprises a panel, a bottom plate, and a ring plate 430, the panel is provided with through holes, the through holes correspond one-to-one to the ring plates 430, the ring plates 430 are arranged in the corresponding through holes, and the bottom plate is connected with the bottom of the panel to form a mounting cavity; the burner 50 corresponds one-to-one to the ring plates 430, the burner 50 is arranged in the corresponding ring plate 430, and the injection pipe of the burner 50 is located in the mounting cavity; the pot rack 60 corresponds one-to-one to the burners 50, the pot rack 60 is placed on the ring plate 430 and is sleeved outside the corresponding burner 50; in addition, as shown in the figure, Figure 1 The number of the burners 50 can be two, and the two burners 50 are arranged side by side on the panel assembly 40.

[0115] It should be further noted that, as shown in the figure, Figure 1 , Figure 2 Each burner 50 is provided with the extinguishing assembly 20 and the sensor assembly 10, the extinguishing assembly 20 is arranged in the mounting cavity, the sensor assembly 10 is located on the ring plate 430, and the sensor assembly 10 is located in the pot rack 60.

[0116] In some embodiments, the first detection signal is a real-time detection temperature of the panel assembly 40, the second detection signal is a real-time detection concentration of the leaked gas, and the third detection signal is a fire state of the panel assembly 40.

[0117] By detecting the temperature of the gas stove, the concentration of the gas, and the fire state, respectively, the working state of the gas stove is monitored from multiple dimensions and aspects, which not only ensures the effective use of the fire extinguishing assembly and further improves the safety performance of the gas stove, but also avoids the misactivation of the fire extinguishing assembly.

[0118] It should be noted that the fire state includes a normal fire state and an abnormal fire state. The normal fire state is that the burner 50 of the gas stove is normally ignited for cooking, and the fire of the burner 50 does not burn to the fire extinguishing port 410. The abnormal fire state is that the fire burns to the fire extinguishing port 410, and the fire burn sensor detects abnormal fire.

[0119] In some embodiments, the first condition is that the real-time detection temperature is greater than or equal to a preset temperature threshold; the second condition is that the real-time detection 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.

[0120] It should be noted that the controller 30 pre-sets the preset temperature threshold and the preset concentration threshold, and the controller 30 compares the received first detection signal and the second detection signal with the above-mentioned 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 fire state, the controller 30 controls the fire extinguishing assembly 20 to extinguish the fire. For example, the preset temperature threshold is 100°C.

[0121] It should also be noted that if the first detection signal meets the first condition, the second detection signal meets the second condition, and the third detection signal does not meet the third condition, the controller notifies the user.

[0122] If the first detection signal does not meet the first condition, the second detection signal meets the second condition, and the third detection signal does not meet the third condition, the controller notifies the user.

[0123] If the first detection signal meets the first condition, the second detection signal does not meet the second condition, and the third detection signal does not meet the third condition, the monitoring is continued.

[0124] For example, Figure 2As shown, in some embodiments, the fire extinguishing assembly 20 includes a fire extinguishing section 210, a nozzle 220, a button 230, and a drive section 240; the fire extinguishing section 210 contains a fire extinguishing agent; the nozzle 220 is connected to the fire extinguishing section 210; the button 230 is located at one end of the fire extinguishing section 210; the drive section 240 is electrically connected to the controller 30, and the drive section 240 is configured to press the button 230 to cause the fire extinguishing agent to be sprayed out through the nozzle 220.

[0125] Pressing button 230 via drive unit 240 activates fire extinguishing unit 210 for fire extinguishing operations. In case of abnormal operation, controller 30 controls drive unit 240 to press button 230, and fire extinguishing agent in fire extinguishing unit 210 is sprayed out through nozzle 220 to extinguish the fire in time and prevent it from causing a fire.

[0126] like Figure 3 As shown, in some embodiments, the extinguishing agent includes a gaseous extinguishing agent and a dry powder extinguishing agent. The extinguishing unit 210 includes a housing 2101, a partition 2102, a puncture member 2105, and a drain pipe 2106. The partition 2102 is disposed inside the housing 2101 to divide the housing 2101 into a first storage area 2103 and a second storage area 2104. The gaseous extinguishing agent is located in the first storage area 2103, and the button 230 is located at the end of the first storage area 2103 away from the second storage area 2104. The dry powder extinguishing agent is located in the second storage area 2104. The puncture member 2105 is disposed inside the first storage area 2103, and one end is connected to the button 230. The drain pipe 2106 passes through the puncture member 2105 and 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.

[0127] The housing 2101 is divided into two independent and non-communicating storage areas, a first storage area 2103 and a second storage area 2104, by a partition 2102. Pressing the button 230 with the drive unit 240 causes the button 230 to move the piercing member 2105 toward the partition 2102. The piercing member 2105 pierces the partition 2102, making the first storage area 2103 and the second storage area 2104 connected. Under the action of pressure difference, the gaseous fire extinguishing agent flows rapidly from the first storage area 2103 to the second storage area 2104. The gaseous fire extinguishing agent and the dry powder fire extinguishing agent are fully mixed and enter the liquid discharge pipe 2106. The gaseous 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 fire on the gas stove.

[0128] It should be noted that gaseous fire extinguishing agents include, but are not limited to, high-pressure nitrogen.

[0129] It is also to be noted that the partition 2102 is provided with a first perforation through which the pouring tube 2106 penetrates, and the pouring tube 2106 is in sealing connection with the inner wall of the first perforation, so as to avoid the gas fire extinguishing agent from entering the second storage area 2104 through the gap between the pouring tube 2106 and the first perforation when the fire extinguishing is not needed. In addition, the piercing member 2105 has a spacing between the end close to the partition 2102 and the partition 2102 when the fire extinguishing is not needed.

[0130] It is also to be noted that the button 230 is provided with a second perforation through which the spray pipe 220 penetrates, and the spray pipe 220 penetrates into the second perforation and is in communication with the first end of the pouring tube 2106; the button 230 has a spacing with the first end of the pouring tube 2106, so as to avoid the interference between the button 230 and the pouring tube 2106 after the button 230 is pressed, and affect the normal pressing of the button 230; in addition, the end of the pouring tube 2106 far away from the spray pipe 220 is deeply inserted into the fire extinguishing agent, and is most likely close to the second end, so that the gas fire extinguishing agent entering the second storage area 2104 can be fully mixed with the dry powder fire extinguishing agent.

[0131] As shown in FIG. 4, Figure 2 In some embodiments, the driving part 240 includes a shell 2401, an air bag 2402 and an inflator 2403; the shell 2401 is provided with a socket into which the button 230 is inserted; the air bag 2402 is arranged in the shell 2401; the inflator 2403 is arranged on the panel assembly 40 and is in electrical connection with the controller 30, and the inflator 2403 is in communication with the air bag 2402 in response to the inflation instruction issued by the controller 30, so as to make the air bag 2402 inflate and press the button 230.

[0132] The air bag 2402 is inflated by the inflator 2403, so that the volume of the air bag 2402 gradually increases, and the inflated air bag 2402 presses the button 230, and the button 230 drives the piercing member 2105 to move, so that the piercing member 2105 pierces the partition 2102.

[0133] It is to be noted that the inflator 2403 includes but is not limited to a gas pump, and the controller 30 controls the opening and closing of the inflator 2403, so that the inflator 2403 can automatically inflate the air bag 2402 and make the air bag 2402 inflate; in addition, the inflator 2403 can be connected with the air bag 2402 through an inflation pipe, and a valve is arranged on the inflation pipe, and the valve is in electrical connection with the controller 30; when the fire extinguishing part 210 completes the fire extinguishing, the controller 30 controls the inflator 2403 to be closed, and the inflator 2403 stops inflating the air bag 2402, and the controller 30 can also control the valve to be opened, the air bag 2402 leaks air and the volume of the air bag 2402 becomes smaller, and the button 230 returns to the original state after losing the pressing force.

[0134] It should be noted that in some embodiments, the inflator 2403 can be replaced by a driving member, including but not limited to an electric push rod, which is arranged in the housing 2401 and is electrically connected to the controller 30, and the telescopic rod of the driving member is connected to the push button 230, and the driving member extends the telescopic rod to press the push button 230 in response to the inflating instruction sent by the controller 30.

[0135] As shown in Figure 1 , Figure 2 In some embodiments, the panel assembly 40 is provided with a fire extinguishing port 410, and the spray pipe 220 is arranged 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.

[0136] By setting the distance between the fire extinguishing port 410 and the burner 50 of the gas stove to be 6-11 cm, the fire extinguishing effect is guaranteed while the spray pipe 220 is protected. On the one hand, the distance between the fire extinguishing port 410 and the burner 50 is too small to avoid the fire burning sensor in the fire extinguishing port 410 from misdetecting normal ignition, and at the same time, the flame of the burner 50 of the gas stove in normal ignition also avoids damaging the spray pipe 220; on the other hand, the distance between the fire extinguishing port 410 and the burner 50 is too large to cause the fire extinguishing agent sprayed by the spray pipe 220 to fail to guarantee the fire extinguishing effect when the gas stove is abnormally ignited.

[0137] It should be noted that the fire extinguishing port 410 is arranged on the ring plate 430.

[0138] It should be noted that the distance between the fire extinguishing port 410 and the burner 50 of the gas stove is 6-11 cm, and preferably, the distance between the fire extinguishing port 410 and the burner 50 of the gas stove is 10 cm.

[0157] It should be further noted that the partition plate 2102 is provided with a first perforation through which the pouring pipe 2106 penetrates, and the pouring pipe 2106 is sealingly connected to the inner wall of the first perforation to avoid the gas fire extinguishing agent entering the second storage area 2104 through the gap between the pouring pipe 2106 and the first perforation when the fire extinguishing is not needed. In addition, when the fire extinguishing is not needed, the piercing member 2105 has a spacing between the end close to the partition plate 2102 and the partition plate 2102.

[0158] It should be further noted that the button 230 is provided with a second perforation through which the spray pipe 220 penetrates, the spray pipe 220 penetrates into the second perforation and is connected to the first end of the pouring pipe 2106 in communication; the button 230 and the first end of the pouring pipe 2106 have a spacing therebetween to avoid interference between the button 230 and the pouring pipe 2106 after the button 230 is pressed, affecting the normal pressing of the button 230; in addition, the end of the pouring pipe 2106 away from the spray pipe 220 is deeply inserted into the fire extinguishing agent and is likely to be close to the second end, so that the gas fire extinguishing agent entering the second storage area 2104 can be fully mixed with the dry powder fire extinguishing agent.

[0159] As shown in Figure 2 some embodiments, the driving part 240 comprises a shell 2401, an air bag 2402 and an inflator 2403; the shell 2401 is provided with a hole for inserting the button 230; the air bag 2402 is arranged in the shell 2401; the inflator 2403 is arranged on the panel assembly 40 and electrically connected with the controller 30, and the inflator 2403 is communicated with the air bag 2402 in response to the inflation instruction from the controller 30 to inflate the air bag 2402 to press the button 230.

[0160] The air bag 2402 is inflated by the inflator 2403, and the volume of the air bag 2402 gradually increases, the inflated air bag 2402 presses the button 230, and the button 230 drives the puncture part 2105 to move, so that the puncture part 2105 punctures the partition plate 2102.

[0161] It should be noted that the inflator 2403 includes but is not limited to a gas pump, and the controller 30 controls the opening and closing of the inflator 2403, so that the inflator 2403 can automatically inflate the air bag 2402 to make the air bag 2402 inflate; in addition, the inflator 2403 can be connected with the air bag 2402 through an inflation pipe, and a valve is arranged on the inflation pipe, and the valve is electrically connected with the controller 30; when the extinguishing part 210 completes the extinguishing, the controller 30 controls the inflator 2403 to close, and the inflator 2403 stops inflating the air bag 2402, and the controller 30 can also control the valve to open, the volume of the air bag 2402 is reduced, and the button 230 returns to the original state after losing the pressing force.

[0162] It should be further noted that in some embodiments, the inflator 2403 can be replaced by a driving part, which includes but is not limited to an electric push rod, and the driving part is arranged in the shell 2401 and electrically connected with the controller 30, and the telescopic rod of the driving part is connected with the button 230, and the driving part extends the telescopic rod in response to the inflation instruction from the controller 30 to press the button 230.

[0163] As shown in Figure 1 , Figure 2 some embodiments, the panel assembly 40 is provided with an extinguishing port 410, and the spray pipe 220 is arranged in the extinguishing port 410, wherein the distance between the extinguishing port 410 and the burner 50 of the gas stove is 6-11 cm.

[0164] By setting the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove to 6-11cm, the fire extinguishing effect is ensured while protecting the nozzle 220. This avoids the fire extinguishing port 410 being too close to the burner head 50, preventing the flame sensor inside the fire extinguishing port 410 from falsely detecting normal ignition, and also preventing the flame from the burner head 50 damaging the nozzle 220 when the gas stove is normally ignited. On the other hand, it also avoids the fire extinguishing port 410 being too far from the burner head 50, which would prevent the extinguishing agent sprayed from the nozzle 220 from being ineffective in extinguishing an abnormal fire in the gas stove.

[0165] It should be noted that the fire extinguishing port 410 is located on the ring plate 430.

[0166] It should also be noted that the distance between the fire extinguishing port 410 and the burner head 50 of the gas stove is 6-11cm, preferably 10cm.

[0167] like Figure 1 , Figure 2 As shown, in some embodiments, the sensing components include a temperature sensor 110, an odor sensor 120, and a fire sensor; the temperature sensor 110 is disposed on the panel assembly 40 and 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 electrically connected to the controller 30, and the odor sensor 120 is configured to detect odors and generate a corresponding second detection signal; the fire sensor is disposed inside the fire extinguishing port 410 and electrically connected to the controller 30, and the fire sensor is configured to detect the fire state and generate a corresponding third detection signal.

[0168] The temperature sensor 110 detects the temperature of the panel assembly 40, the odor sensor 120 detects the concentration of the gas, and the flame sensor detects the ignition status, thereby realizing real-time detection of the working status 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.

[0169] In some embodiments, the fire sensor may be a silk-based ionized hydrogel (SIH) fiber that can detect fire.

[0170] 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.

[0171] By setting the distance between the temperature sensor 110 and / or the peculiar smell sensor 120 and the burner 50 to 5-7cm, the sensor is protected while ensuring accurate detection effect. On the one hand, the distance between the sensor and the burner 50 is avoided to be too small, and the flame of the normally ignited burner 50 of the gas stove causes damage to the nozzle 220; on the other hand, the distance between the sensor and the burner 50 is also avoided to be too large, which causes the sensor to be inaccurate in detecting temperature and peculiar smell.

[0172] It should be noted that the distance between the temperature sensor 110 and / or the peculiar smell sensor 120 and the burner 50 of the gas stove is 5-7cm, preferably, the distance between the temperature sensor 110 and / or the peculiar smell sensor 120 and the burner 50 of the gas stove is 6cm.

[0173] In some embodiments, the gas stove protection structure further comprises a gas leakage detector and an alarm; the gas leakage detector is arranged on the panel assembly 40 and electrically connected with the controller 30; the alarm is arranged on the panel assembly 40 and electrically connected with the controller 30.

[0174] The gas leakage detector can detect the gas leakage condition, and the alarm is arranged to alarm and remind the user in time when the gas stove is in an abnormal working state.

[0175] 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 normally ignited state, the controller 30 controls the alarm to alarm and 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 normally ignited state, the controller 30 controls the alarm to alarm and 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 normally ignited state, the working state of the gas stove is continuously monitored.

[0176] It should be further noted that the mobile phone of the user can be communicatively connected with the controller 30, including but not limited to communicatively connected through Bluetooth and wireless network, so that the user can obtain the working state of the gas stove in real time, and know the abnormal situation of the gas stove in time.
