Description

Technical Field

[0001] This invention relates to the field of stove technology, specifically to a stove control method and a stove. Background Technology

[0002] Gas stoves and other cooktops, whether they require pulse ignition or have a control panel, all require electricity to operate. Power supply methods typically include battery power and plug-in power adapters. However, since most homes do not have power outlets for adapters where gas stoves are located, using adapters is inconvenient; and battery-powered gas stoves require regular battery replacements, which also causes inconvenience for users.

[0003] To overcome the inconvenience of connecting adapters and using batteries, some gas stoves in related technologies are equipped with thermoelectric generators. These generators include thermoelectric plates, whose hot end utilizes the temperature difference between the hot and cold ends of the burner cap to generate electricity, which is stored in a battery. However, when the user uses the lowest flame setting, the temperature difference between the hot and cold ends is small, making it difficult for the electricity generated by the thermoelectric plate to compensate for the battery power consumed by the user. If the user habitually uses the lowest flame setting for an extended period, this can lead to a power deficit. Summary of the Invention

[0004] In view of this, the present invention provides a control method and a stove for a gas stove, so as to solve the problem that the electrical energy generated by the thermoelectric generator of the stove is difficult to make up for the electrical energy consumed by using the gas stove.

[0005] In a first aspect, the present invention provides a method for controlling a stove, the stove comprising a flame end and a thermoelectric generator, the control method comprising:

[0006] Obtain the flame state at the flame end;

[0007] When the flame state changes, the thermoelectric generator of the thermoelectric power generation device is controlled to move according to a preset moving strategy, and the power generation of the thermoelectric generator is detected in real time during the moving process;

[0008] Obtain the maximum power output of the thermoelectric generator, obtain the optimal position of the thermoelectric generator corresponding to the maximum power output, and adjust the thermoelectric generator to the optimal position.

[0009] Beneficial effects: By adjusting the position of the thermoelectric generator plate according to the flame state at the flame end, the temperature difference between the hot and cold ends of the thermoelectric generator plate is maintained under the current flame state, i.e., by adjusting the distance between the thermoelectric generator plate and the flame end. This maximizes the power generation of the thermoelectric generator plate, ensuring that the thermoelectric generator plate can obtain better power generation under different flame states, and preventing the user from experiencing insufficient power output when using the minimum flame for a long time.

[0010] In one optional implementation, the control of the thermoelectric generator's thermoelectric element to move according to a preset moving strategy, and the real-time detection of the thermoelectric generator's power generation during the movement, includes:

[0011] Control the thermoelectric generator to move away from the flame end, or control the thermoelectric generator to move closer to the flame end;

[0012] The power generation of the thermoelectric generator is monitored in real time during the movement, and the variation pattern of the power generation is obtained.

[0013] The subsequent movement of the thermoelectric generator is controlled according to the aforementioned change pattern.

[0014] Beneficial effects: First, the thermoelectric generator is moved away from or closer to the flame end, and the power generation at different positions during the movement is acquired in real time. Then, the variation pattern of these power generation is acquired. Based on the variation pattern and the relationship between the power generation and the flame distance, the subsequent movement can be controlled more accurately, making it easier to adjust the thermoelectric generator to the optimal position.

[0015] In one optional implementation, obtaining the variation pattern of the power generation includes:

[0016] The power generation obtained from two consecutive detections is acquired;

[0017] By comparing the magnitude of the power generation obtained from two adjacent detections, the pattern of the power generation decreasing or increasing can be obtained.

[0018] Beneficial effects: Comparing the power generation obtained from two adjacent measurements allows for a more accurate and rapid identification of the power generation variation pattern. It also quickly identifies the maximum power generation displayed by the relationship between power generation and flame distance, avoiding the waste of time searching for patterns and the kinetic energy used to move the thermoelectric generator. Furthermore, comparing only the power generation obtained from two adjacent measurements simplifies the comparison process and yields accurate results.

[0019] In one optional implementation, controlling the subsequent movement of the thermoelectric generator according to the changing pattern includes:

[0020] When the power generation changes in a pattern of decreasing power generation...

[0021] The thermoelectric generator is controlled to move in the opposite direction until the power generation decreases again.

[0022] Beneficial effect: If the power generation decreases first, it means that we are getting further and further away from the optimal position. If we move in the opposite direction, we are getting closer and closer to the optimal position. The power generation will increase first and then decrease again. Before it decreases again, we can say that we have reached the maximum power generation.

[0023] In one optional implementation, obtaining the maximum power output of the thermoelectric generator includes:

[0024] The power generation power obtained from two adjacent detections when the power generation power decreases again is obtained, and the power generation power obtained from the earlier detection is determined as the maximum power generation power.

[0025] Beneficial effects: Through the above steps, the maximum power generation can be found relatively quickly and easily. Then, the optimal position of the thermoelectric generator can be obtained based on the maximum power generation, and the thermoelectric generator can be adjusted to the optimal position to achieve the purpose of adjusting the position of the thermoelectric generator according to the flame state to obtain the optimal power generation.

[0026] In one optional implementation, controlling the subsequent movement of the thermoelectric generator according to the changing pattern includes:

[0027] The change pattern of the power generation is obtained as an increase in the power generation;

[0028] The thermoelectric generator is controlled to continue moving until the power generation begins to decrease.

[0029] Beneficial effect: If the power generation increases first, it means that we are getting closer to the optimal position. Continue moving until the power generation starts to decrease. It is then considered that the maximum power generation has been reached before the decrease.

[0030] In one optional implementation, obtaining the maximum power output of the thermoelectric generator includes:

[0031] The power generation power obtained from two consecutive detections when the power generation power begins to decrease is obtained, and the power generation power obtained from the earlier detection is determined as the maximum power generation power.

[0032] Beneficial effects: Through the above steps, the maximum power generation can be found relatively quickly and easily. Then, the optimal position of the thermoelectric generator can be obtained based on the maximum power generation, and the thermoelectric generator can be adjusted to the optimal position to achieve the purpose of adjusting the position of the thermoelectric generator according to the flame state to obtain the optimal power generation.

[0033] In one alternative implementation, the change in flame state includes:

[0034] The flame at the flame end changes from nothing to something, from small to large, or from large to small.

[0035] Secondly, the present invention also provides a stove, comprising:

[0036] The stove body;

[0037] The flame end is located on the stove body;

[0038] A thermoelectric generator, comprising a thermoelectric generator plate, which is slidably disposed on the stove body, with the hot end of the thermoelectric generator plate corresponding to the flame end;

[0039] The power mechanism is fixedly connected to the stove body, and the power output end is connected to the thermoelectric generator.

[0040] The controller is communicatively connected to the flame end, the thermoelectric generator, and the power mechanism, and is used to execute the control method of the stove described above.

[0041] Beneficial effects: The hot end of the thermoelectric generator is positioned facing the flame end to correspond with it, absorbing heat from the flame end and creating a temperature difference between the hot end and the cold end of the thermoelectric generator. This temperature difference is then used to generate electrical energy that is stored in the battery. The controller can obtain the flame state at the flame end and, when the flame state changes, drive the thermoelectric generator to move according to a preset movement strategy through the power output end of the power mechanism. The controller can also detect the power generation of the thermoelectric generator in real time during its movement, obtain the maximum power generation of the thermoelectric generator, determine the optimal position of the thermoelectric generator corresponding to the maximum power generation, and adjust the thermoelectric generator to the optimal position.

[0042] In one optional embodiment, the thermoelectric power generation device further includes:

[0043] The heat collection plate is connected to the hot end of the thermoelectric generator.

[0044] A cover plate is connected to the cold end of the thermoelectric generator.

[0045] A heat dissipation structure is slidably mounted on the stove body and connected to the power output end of the power mechanism. The heat dissipation structure is connected to the cover plate through a heat dissipation pipe.

[0046] Beneficial effects: The heat collection plate faces the flame end to collect heat from the flame end and transfer it to the hot end of the thermoelectric generator. The cover plate is connected to the cold end of the thermoelectric generator and is integrated with the heat dissipation structure via heat dissipation pipes. This allows the entire thermoelectric generator to move synchronously when the power mechanism drives the heat dissipation structure, enabling the thermoelectric generator to move away from or towards the flame end. This avoids the power output end of the power mechanism directly connecting to the thermoelectric generator, which could affect the temperature difference of the thermoelectric generator. The heat dissipation pipes not only transfer heat from the cover plate and the cold end of the thermoelectric generator to the heat dissipation structure for cooling, but also support and fix the cover plate, thermoelectric generator, and heat collection plate.

[0047] In one optional implementation, the heat dissipation structure includes:

[0048] A water tank is slidably mounted on the stove body and connected to the power output end of the power mechanism; the water tank is suitable for holding heat dissipation liquid.

[0049] A radiator is installed inside the water tank; the radiator is connected to the cover plate via the heat dissipation pipe.

[0050] A water pump, connected to the water tank and communicating with the controller, is adapted to drive the flow of cooling liquid within the water tank.

[0051] Beneficial effects: The water tank contains water and other heat-dissipating liquids, which can quickly reduce the temperature of the radiator and achieve a better heat dissipation effect; the water tank is slidably installed inside the stove body and connected to the power output end of the power mechanism, which can facilitate the synchronous movement of the cover plate, thermoelectric generator and heat collection plate through the radiator and heat dissipation pipe; the water pump can drive the heat-dissipating liquid in the water tank to flow, improving the heat dissipation effect of the heat dissipation structure.

[0052] In one optional embodiment, the top of the stove body is provided with a slide rail; the water tank is slidably disposed inside the stove body, and the power mechanism is connected inside the stove body; the heat dissipation pipe is slidably disposed through the slide rail.

[0053] Beneficial effects: The heat dissipation pipe runs through the slide rail, with both ends connecting to the cover plate and the radiator respectively. The slide rail design prevents the heat dissipation pipe from interfering with the movement of the cooktop body. The water tank and power mechanism are located inside the cooktop body, allowing them to be concealed and preventing them from occupying too much space on top of the cooktop body, thus affecting the use of the cooking area.

[0054] In one alternative embodiment, the heat dissipation structure further includes pulleys connected to the bottom of the water tank.

[0055] Beneficial effects: The pulley design reduces the sliding friction and noise of the water tank. Attached Figure Description

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0068] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0069] According to embodiments of the present invention, in one aspect, a method for controlling a stove is provided, such as... Figures 1 to 5 As shown, the stove includes a flame end 2 and a thermoelectric generator 3, and the control method includes:

[0070] S1. Obtain the flame status of flame end 2;

[0071] S2. When the flame state changes, the thermoelectric generator 31 of the thermoelectric generator 3 is controlled to move according to the preset moving strategy, and the power generation of the thermoelectric generator 31 is detected in real time during the moving process.

[0072] S3. Obtain the maximum power output of the thermoelectric generator 31, obtain the optimal position of the thermoelectric generator 31 corresponding to the maximum power output, and adjust the thermoelectric generator 31 to the optimal position.

[0073] According to the flame state of flame end 2, the position of the thermoelectric generator 31 of the thermoelectric generator 3 is adjusted so that, under the current flame state, the temperature difference between the hot and cold ends of the thermoelectric generator 31 is maintained by adjusting the position of the thermoelectric generator 31, that is, adjusting the distance between the thermoelectric generator 31 and flame end 2, so that the power generation of the thermoelectric generator 31 is maximized. This allows the thermoelectric generator 3 to obtain better power generation under different flame states, preventing the user from having insufficient power when using the minimum flame for a long time.

[0074] The distance between the thermoelectric generator 31 and the flame end 2 is the flame distance, such as... Figure 5 As shown, there is a linear relationship between the flame distance and the power generation of the thermoelectric generator 31. As the flame distance increases, the power generation first gradually increases and then gradually decreases. Therefore, the power generation of the thermoelectric generator 31 is not greater the closer it is to the flame end 2, nor is the power generation of the thermoelectric generator 31 smaller the farther it is from the flame end 2.

[0075] Specifically, when the user uses the lowest flame setting for an extended period, the temperature of the hot end can be increased by reducing the distance between the thermoelectric generator 31 and the flame end 2, thereby increasing the temperature difference between the hot and cold ends. This ensures that the power generation of the thermoelectric generator 31 is at its optimal level, guaranteeing that the electrical energy generated by the thermoelectric generator 31 exceeds the battery power consumed by the user during gas stove operation. When the user adjusts the flame setting from low to high, the flame distance between the thermoelectric generator 31 and the flame end 2 can be increased to prevent damage to the thermoelectric generator 31 caused by the high flame. The power generation of the thermoelectric generator 31 can be adjusted to its maximum power output using the stove control method described in this embodiment. When the user adjusts the flame setting from high to low, the temperature of the hot end can be increased by reducing the flame distance between the thermoelectric generator 31 and the flame end 2. The power generation of the thermoelectric generator 31 can be adjusted to its maximum power output using the stove control method described in this embodiment.

[0076] In one embodiment, step S2 involves controlling the thermoelectric generator 31 of the thermoelectric generator 3 to move according to a preset moving strategy, and detecting the power generation of the thermoelectric generator 31 in real time during the movement, including:

[0077] S21, control the thermoelectric generator 31 to move away from the flame end 2;

[0078] S22. Real-time detection of the power generation of the thermoelectric generator 31 during the movement process, and acquisition of the change pattern of the power generation;

[0079] S23. Control the subsequent movement of the thermoelectric generator 31 according to the change pattern.

[0080] In another embodiment, in step S2, controlling the thermoelectric generator 31 of the thermoelectric generator 3 to move according to a preset moving strategy, and detecting the power generation of the thermoelectric generator 31 in real time during the movement, includes:

[0081] S21, control the thermoelectric generator 31 to move towards the flame end 2;

[0082] S22. Real-time detection of the power generation of the thermoelectric generator 31 during the movement process, and acquisition of the change pattern of the power generation;

[0083] S23. Control the subsequent movement of the thermoelectric generator 31 according to the change pattern.

[0084] Due to such Figure 5As shown, there is a linear relationship between the flame distance and the power generation of the thermoelectric generator 31. As the flame distance increases, the power generation first gradually increases and then gradually decreases. Therefore, in the control method of the stove in this embodiment, the thermoelectric generator 31 can be moved away from or closer to the flame end 2, and the power generation at different positions during the movement can be obtained in real time. Then, the variation law of these power generation values ​​can be obtained, and then the variation law can be combined with... Figure 5 The relationship between the power generation and the distance to the flame shown can be used to control the subsequent movement more accurately, making it easier to adjust the thermoelectric generator 31 to the optimal position.

[0085] In one embodiment, step S22, obtaining the variation pattern of power generation, includes:

[0086] S221. Obtain the power generation obtained from two consecutive detections;

[0087] S222. Compare the power generation obtained from two adjacent detections to obtain the pattern of power generation decreasing or increasing.

[0088] Comparing the power generation data from two consecutive measurements allows for a more accurate and rapid understanding of the patterns in power generation changes, and also helps to quickly identify... Figure 5 The relationship between the power generation and the flame distance shown indicates the maximum power generation, avoiding the need to spend excessive time searching for patterns of change, which wastes both time and the kinetic energy used to move the thermoelectric generator 31. Furthermore, comparing only the power generation obtained from two adjacent measurements simplifies the comparison process and yields more accurate results.

[0089] In one embodiment, step S23, controlling the subsequent movement of the thermoelectric generator 31 according to the changing pattern, includes:

[0090] S231. When the power generation rate changes in the pattern of decreasing power generation...

[0091] S232, control the thermoelectric generator 31 to move in the opposite direction until the power generation decreases again.

[0092] If the power generation decreases first, it means that we are getting further and further away from the optimal position. If we move in the opposite direction, we are getting closer and closer to the optimal position. The power generation will increase first and then decrease again. Before it decreases again, we are considered to have reached the maximum power generation.

[0093] In one embodiment, obtaining the maximum power output of the thermoelectric generator 31 in step S3 includes:

[0094] S31. Obtain the power generation obtained from two adjacent detections when the power generation decreases again, and determine the power generation obtained from the earlier detection as the maximum power generation.

[0095] Through the above steps, the maximum power generation can be found relatively quickly and easily. Then, the optimal position of the thermoelectric generator 31 can be obtained based on the maximum power generation, and the thermoelectric generator 31 can be adjusted to the optimal position to achieve the purpose of adjusting the position of the thermoelectric generator 31 according to the flame state to obtain the optimal power generation.

[0096] In a specific implementation, when a decrease in power generation is detected again, the thermoelectric generator 31 can be controlled to return to the optimal position corresponding to the maximum power generation. Alternatively, the thermoelectric generator 31 can be stopped directly, remaining at the position closest to the optimal position, which can also achieve a larger power generation.

[0097] In one embodiment, step S23, controlling the subsequent movement of the thermoelectric generator 31 according to the changing pattern, includes:

[0098] S233. When the change pattern of power generation is that power generation increases;

[0099] S234. Control the thermoelectric generator 31 to continue moving until the power generation begins to decrease.

[0100] If the power generation initially increases, it indicates that the optimal position is being approached. Continue moving until the power generation begins to decrease, at which point the maximum power generation is considered to have been reached before the decrease.

[0101] In one embodiment, obtaining the maximum power output of the thermoelectric generator 31 in step S3 includes:

[0102] S32. Obtain the power generation obtained from two adjacent detections when the power generation begins to decrease, and determine the power generation obtained from the earlier detection as the maximum power generation.

[0103] Through the above steps, the maximum power generation can be found relatively quickly and easily. Then, the optimal position of the thermoelectric generator 31 can be obtained based on the maximum power generation, and the thermoelectric generator 31 can be adjusted to the optimal position to achieve the purpose of adjusting the position of the thermoelectric generator 31 according to the flame state to obtain the optimal power generation.

[0104] In one embodiment, a change in the flame state includes: the flame at flame end 2 changing from nothing to something, the flame at flame end 2 changing from small to large, or the flame at flame end 2 changing from large to small.

[0105] When the flame goes from nothing to something, it means the flame end 2 is ignited. When the flame at flame end 2 grows from small to large, it means the flame is adjusted from small to large. When the flame at flame end 2 shrinks from large to small, it means the flame is adjusted from large to small. When any of the above situations causes a change in the flame state, the control method of the stove is executed, and the position of the thermoelectric generator 31 is readjusted to generate electricity at the maximum power.

[0106] According to an embodiment of the present invention, in another aspect, a stove is also provided, such as... Figures 6 to 8 As shown, the stove includes a cooker body 1, a flame end 2, a thermoelectric generator 3, a power mechanism 4, and a controller 5. The flame end 2 is mounted on the cooker body 1. The thermoelectric generator 3 includes a thermoelectric generator 31, which is slidably mounted on the cooker body 1, with its hot end corresponding to the flame end 2. The power mechanism 4 is fixedly connected to the cooker body 1, and its power output end is connected to the thermoelectric generator 31. The controller 5 is communicatively connected to the flame end 2, the thermoelectric generator 31, and the power mechanism 4, and is used to execute the aforementioned cooker control method.

[0107] The hot end of the thermoelectric generator 31 is positioned facing the flame end 2 to correspond with the flame end 2, absorbing the heat of the flame end 2, thus creating a temperature difference between the hot end and the cold end of the thermoelectric generator 31, thereby generating electrical energy using the temperature difference and storing it in the battery; the controller 5 can obtain the flame state of the flame end 2, and when the flame state changes, it can drive the thermoelectric generator 31 to move according to a preset movement strategy through the power output end of the power mechanism 4, and can detect the power generation power of the thermoelectric generator 31 in real time during the movement of the thermoelectric generator 31; and obtain the maximum power generation power of the thermoelectric generator 31, obtain the optimal position of the thermoelectric generator 31 corresponding to the maximum power generation power, and adjust the thermoelectric generator 31 to the optimal position.

[0108] According to the flame state of flame end 2, the position of the thermoelectric generator 31 of the thermoelectric generator 3 is adjusted so that, under the current flame state, the temperature difference between the hot and cold ends of the thermoelectric generator 31 is maintained by adjusting the position of the thermoelectric generator 31, that is, adjusting the distance between the thermoelectric generator 31 and flame end 2, so that the power generation of the thermoelectric generator 31 is maximized. This allows the thermoelectric generator 3 to obtain better power generation under different flame states, preventing the user from having insufficient power when using the minimum flame for a long time.

[0109] In a specific implementation, the flame end 2 includes an inner ring burner cap and an outer ring burner cap. When the stove is running at low speed, the flame is generated only at the inner ring burner cap, meaning the flame at flame end 2 is relatively small. When the stove is running at high speed, the flame is generated at the outer ring burner cap, meaning the flame at flame end 2 is relatively large. The power mechanism 4 can be a push rod motor, used to drive the thermoelectric generator 31 to move closer to or further away from the flame end 2. The stove also includes a ignition needle for igniting the gas.

[0110] In one embodiment, the thermoelectric generator 3 further includes a heat collection plate 32, a cover plate 33, and a heat dissipation structure 34; the heat collection plate 32 is connected to the hot end of the thermoelectric generator 31; the cover plate 33 is connected to the cold end of the thermoelectric generator 31; the heat dissipation structure 34 is slidably disposed on the stove body 1 and connected to the power output end of the power mechanism 4, and the heat dissipation structure 34 is connected to the cover plate 33 through a heat dissipation pipe 35.

[0111] The heat collection plate 32 faces the flame end 2 and is used to collect the heat from the flame end 2 and transfer it to the hot end of the thermoelectric generator 31. The cover plate 33 is connected to the cold end of the thermoelectric generator 31 and is integrated with the heat dissipation structure 34 through the heat dissipation pipe 35. This allows the thermoelectric generator 31 to move synchronously when the power mechanism 4 drives the heat dissipation structure 34, enabling the thermoelectric generator 31 to move away from the flame end 2 or towards the flame end 2. This avoids the power output end of the power mechanism 4 being directly connected to the thermoelectric generator 31, which would affect the temperature difference of the thermoelectric generator 31. The heat dissipation pipe 35 serves not only to transfer the heat from the cover plate 33 and the cold end of the thermoelectric generator to the heat dissipation structure 34 for cooling, but also to support and fix the cover plate 33, the thermoelectric generator 31, and the heat collection plate 32.

[0112] In a specific implementation, the heat collection plate 32 is made of metal, which has good thermal conductivity. The thermoelectric generator 31 can generate electricity by utilizing the temperature difference between its cold and hot ends.

[0113] In one embodiment, the heat dissipation structure 34 includes a water tank 341, a radiator 342, and a water pump 343; the water tank 341 is slidably disposed inside the stove body 1 and connected to the power output end of the power mechanism 4; the water tank 341 is suitable for holding heat dissipation liquid; the radiator 342 is disposed inside the water tank 341; the radiator 342 is connected to the cover plate 33 through a heat dissipation pipe 35; the water pump 343 is connected to the water tank 341 and communicates with the controller 5, and is suitable for driving the flow of heat dissipation liquid in the water tank 341.

[0114] The water tank 341 contains water and other heat-dissipating liquids, which can quickly reduce the temperature of the radiator 342 to achieve a better heat dissipation effect. The water tank 341 is slidably installed inside the stove body 1 and connected to the power output end of the power mechanism 4, which can facilitate the synchronous movement of the cover plate 33, the thermoelectric generator 31 and the heat collection plate 32 through the radiator 342 and the heat dissipation pipe 35. The water pump 343 can drive the heat-dissipating liquid in the water tank 341 to flow, thereby improving the heat dissipation effect of the heat dissipation structure 34.

[0115] In one embodiment, the top of the cooktop body 1 is provided with a slide rail; the water tank 341 is slidably disposed inside the cooktop body 1, and the power mechanism 4 is connected inside the cooktop body 1; the heat dissipation pipe 35 is slidably disposed through the slide rail.

[0116] The heat dissipation pipe 35 passes through the slide rail, and its two ends are connected to the cover plate 33 and the radiator 342 respectively. The slide rail design can prevent the heat dissipation pipe 35 from interfering with the movement of the stove body 1. The water tank 341 and the power mechanism 4 are located inside the stove body 1, which can hide the water tank 341 and the power mechanism 4, and prevent the water tank 341 and the power mechanism 4 from occupying too much space on the top of the stove body 1, thus affecting the use of the cooking area.

[0117] In one embodiment, the heat dissipation structure 34 further includes a pulley 344 connected to the bottom of the water tank 341.

[0118] The pulley 344 is designed to reduce the sliding friction and noise of the water tank 341.

[0119] like Figure 4As shown, in a specific embodiment, when the flame state changes, the controller 5 detects the initial power generation P of the thermoelectric generator 31; the change in flame state here includes the flame at the flame end 2 changing from nothing to something, the flame at the flame end 2 increasing in size, or the flame at the flame end 2 decreasing in size; the controller 5 controls the power output end of the power mechanism 4 to drive the water tank 341 to move, thereby moving the thermoelectric generator 31 away from the flame end 2, or the controller 5 controls the power output end of the power mechanism 4 to drive the water tank 341 to move, thereby moving the thermoelectric generator 31 closer to the flame end 2; the controller 5 detects the temperature difference in real time. If the power output P' of the thermoelectric generator 31 is greater than P', the controller 5 drives the thermoelectric generator 31 to move in the reverse direction through the power output terminal of the power mechanism 4. During the movement, the power output of the thermoelectric generator 31 is detected in real time. Let the power output obtained from two adjacent detections be P1 and P2, respectively. The earlier detection time is P1 and the later detection time is P2. If P1 > P2, then P1 is the maximum power output of the thermoelectric generator 31. The thermoelectric generator 31 is moved to the optimal position corresponding to P1 or stays at the position corresponding to P2. If P1 < P2, then the reverse movement continues until P1 > P2. If P < P', the controller 5 controls the power output of the power mechanism 4 to continue driving the water tank 341 to move in the original direction, and drives the thermoelectric generator 31 to continue moving in the original direction. During the movement, the power generation of the thermoelectric generator 31 is monitored in real time, and the power generation obtained from two adjacent detections is set as P3 and P4, with the earlier detection time being P3 and the later detection time being P4. If P3 > P4, then P3 is the maximum power generation of the thermoelectric generator 31, and the thermoelectric generator 31 is moved to the optimal position corresponding to P3, or it can stay at the position corresponding to P3; if P3 < P4, then the movement continues until P3 > P4.
