[0070] The monitorable electric flame stove of this utility model is described in detail below with reference to the accompanying drawings.

[0071] Reference Figures 1 to 8 As shown, the monitorable electric flame stove provided according to the embodiment of this utility model includes a stove shell 10, a stove head 20, a control module 30, a plasma drive circuit 31, a positioning module 32, and a wireless communication module 33.

[0072] Specifically, the stove shell 10 is made of high-temperature resistant, corrosion-resistant and flame-retardant materials, such as stainless steel, and the stove shell 10 can be placed on flat objects such as stovetops and tabletops.

[0073] The burner head 20 is located on the top of the burner shell 10, and the burner head 20 has plasma electrodes 201. Each electrode of the plasma electrode 201 is made of a high-temperature resistant and highly conductive metal material to ensure a stable and uniform plasma flame is generated after high-voltage driving.

[0074] The control module 30 is located inside the stove shell 10. The input terminal of the plasma drive circuit 31 is connected to the control module 30, and the output terminal of the plasma drive circuit 31 is connected to the plasma electrode 201 to output high voltage under the control of the control module 30, so that the plasma electrode 201 generates a plasma flame.

[0075] The positioning module 32 is connected to the control module 30 to obtain the location information of the electric flame stove. The location information provided by this positioning module 32 not only provides data support for monitoring the equipment's usage status, but also functions as a positioning tool in special situations (such as for elderly people or households with only one person living alone). Once an abnormal departure is detected, the location information is promptly transmitted to the monitoring terminal via the wireless communication module 33 for remote monitoring. This positioning module 32 can be a Beidou positioning module 32 or a GPS positioning module 32.

[0076] The wireless communication module 33 is connected to the control module 30 to transmit the location and usage data of the electric stove to the remote monitoring terminal 43. In other words, the wireless communication module 33 enables information transmission between the remote monitoring terminal 43 and the electric stove. This wireless communication module 33 can be a 4G / 5G communication module, or it can include a Wi-Fi module, etc. During device operation, the wireless communication module 33 uploads the device's usage data and location information to the monitoring terminal in real time. Usage data includes, but is not limited to, operating status, power level, and usage time, ensuring that remote monitoring personnel are promptly informed of the electric stove's status. Furthermore, when these usage data show abnormalities, alarm information can be immediately pushed to the remote monitoring terminal 43, ensuring that monitoring personnel are promptly informed of any abnormalities.

[0077] According to the embodiments of this utility model, the monitorable electric flame stove realizes the remote monitoring function by configuring the positioning module 32 and the wireless communication module 33, which enables users to obtain the location information and usage data of the electric flame stove in real time. In particular, it provides safety protection for remote monitoring of special groups such as the elderly, reduces the safety hazards of using the stove, and allows family members or caregivers to understand the usage of the electric flame stove in a timely manner and intervene quickly when abnormal conditions occur. In essence, it ensures high efficiency and energy saving while enhancing safety performance.

[0078] Reference Figure 2 As shown, in one embodiment of this utility model, an environmental sensor 34 is also included. The environmental sensor 34 is connected to the control module 30 and is used to detect environmental data.

[0079] The control module 30 is also used to control and adjust the output power of the plasma drive circuit 31 or automatically cut off the high voltage output of the plasma drive circuit 31 when abnormal environmental data and / or usage data are detected, and to control the wireless communication module 33 to send early warning information to the remote monitoring terminal 43.

[0080] In this embodiment, an environmental sensor 34 is added to the electric flame stove. This environmental sensor 34 can collect environmental parameters in real time, such as at least one of temperature, concentration of harmful gases, and smoke. The collected data is preprocessed and then transmitted to the control module 30 to provide accurate environmental information for monitoring.

[0081] The control module 30 not only monitors the stove's usage data (such as operating status, power, and usage time), but also synchronously monitors the data collected by the environmental sensor 34. When the control module 30 detects that the environmental data reaches or exceeds a preset safety threshold, it determines that there is a potential safety risk in the environment. At this time, the control module 30 can dynamically adjust the output power of the plasma drive circuit 31 to reduce the operating power of the equipment and reduce the impact of the flame on the environment, depending on the situation. On the other hand, in the event of a large abnormal fluctuation or an emergency, the control module 30 will automatically cut off the high-voltage power output of the plasma drive circuit 31, thereby effectively preventing potential safety accidents from occurring.

[0082] At the same time, the control module 30 transmits the early warning information to the remote monitoring terminal 43 in a timely manner through the wireless communication module 33, so that the monitoring personnel or their families can obtain abnormal information about the equipment operation as soon as possible, and take necessary intervention measures quickly.

[0083] By adding an environmental sensor 34 and combining it with the control module 30 for real-time monitoring of environmental and usage data and anomaly handling measures, the electric flame stove in this embodiment further enhances its adaptive protection capability against environmental risks, ensuring that the flame output can be quickly adjusted or interrupted in abnormal situations, and at the same time, the early warning information is promptly transmitted to the remote monitoring terminal 43, thereby greatly improving the overall safety and reliability and providing more comprehensive safety protection for special groups such as the elderly and people living alone.

[0084] In one embodiment of the present invention, the environmental sensor 34 includes at least a temperature sensor, and the top surface of the stove shell 10 has a protruding sealing cap 203. The temperature sensor is disposed inside the sealing cap 203 and maintains a predetermined distance from the stove head 20.

[0085] Reference Figure 1 As shown, in this embodiment, the environmental sensor 34 includes at least a temperature sensor. To ensure that the temperature sensor can accurately collect ambient temperature information without external interference, the top surface of the stove shell 10 has a protruding sealing cap 203. The sealing cap 203 is made of a high-temperature resistant and corrosion-resistant material and is integrally processed with the overall structure of the stove shell 10, which not only enhances the sealing protection of the equipment, but also provides a relatively stable working environment for the temperature sensor.

[0086] The temperature sensor maintains a predetermined distance from the burner head 20, effectively preventing the high-temperature flame from directly affecting the sensor's measurement accuracy while ensuring timely and accurate acquisition of ambient temperature data. The data collected by the temperature sensor is pre-processed and transmitted to the control module 30, serving as a crucial reference for the safe operation of the equipment. When the temperature sensor detects an abnormal ambient temperature, the control module 30 can promptly adjust the power or cut off the power, and alert the remote monitoring terminal 43, ensuring necessary measures are taken before a safety risk occurs.

[0087] In other words, by configuring a temperature sensor, real-time monitoring of the stove's ambient temperature is achieved, and the detection results are accurately fed back to the control module 30. This enables timely adjustment or power-off measures and remote early warning when abnormal temperature changes occur in the environment, ensuring the safe operation of the equipment and the safety of the user.

[0088] Reference Figure 2 and Figure 7 As shown, in some embodiments of this utility model, the monitorable electric flame stove further includes a button circuit 35, which is connected to the control module 30. The button circuit 35 includes at least one power adjustment button for power adjustment control of the plasma drive circuit through the control module 30.

[0089] The electric flame stoves in related technologies mainly control the power of the plasma flame by adjusting the input direct current. This control method generally includes front-end transformer control, which converts alternating current into voltage-controllable direct current, and then transforms it at the next stage to generate the electric flame. This circuit structure is complex, has high production costs, poor adjustment effect, and is difficult to meet application requirements.

[0090] In this embodiment, the user can receive adjustment commands from the control module 30 by operating the power adjustment key, and the module directly adjusts the power output of the plasma drive circuit according to preset parameters. This adjustment method avoids the complex process of adjusting the flame power by adjusting the input DC power in related technologies. From power conversion to subsequent transformer output, the entire adjustment chain is greatly simplified, which not only significantly reduces circuit design and manufacturing costs, but also improves response speed and adjustment accuracy through direct adjustment, ensuring that the plasma flame can maintain good stability under different requirements. In addition, it is also convenient for users to operate intuitively, improving the convenience and practicality of the equipment.

[0091] Reference Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the plasma driving circuit 31 includes a PWM driving circuit 311 and a boost circuit 312. The PWM driving circuit 311 is connected to the control module 30 and is used to generate a PWM driving signal to provide precise pulse waveform control for subsequent boosting.

[0092] The boost circuit 312 is connected to the output of the AC / DC converter circuit 40 for converting low-voltage DC to high-voltage electricity. The boost circuit 312 includes a transformer T1, which comprises a first coil T1A and a second coil T1B. The first coil T1A modulates the input DC under the action of the PWM drive signal, while the second coil T1B outputs high-voltage electricity. The plasma electrode 201 is connected to the second coil T1B. In other words, under the action of the PWM drive signal, the first coil T1A modulates the input DC, transferring pulse energy to the transformer; subsequently, the second coil T1B outputs high-voltage electricity, directly powering the plasma electrode 201 to generate a stable and reliable plasma flame.

[0093] Through the structure of the plasma drive circuit 31, the PWM drive circuit 311 not only ensures precise control of the current pulses, but also achieves high-voltage output in conjunction with the transformer T1 in the boost circuit 312. The plasma electrode 201 is directly connected to the second coil T1B of the transformer T1, enabling the high-voltage electricity to be efficiently transmitted to the plasma region, ensuring the stability and combustion effect of the flame. Thus, this embodiment achieves precise control and efficient energy conversion of the plasma flame driving process. It not only simplifies the plasma flame start-up and control process, but also significantly improves the efficiency and stability of the entire system.

[0094] Reference Figure 2 and Figure 6 As shown, in one embodiment of this utility model, the monitorable electric flame stove further includes a current sampling circuit 36 ​​and a voltage sampling circuit 37. The current sampling circuit 36 ​​is connected to the plasma electrode 201 to detect the current of the plasma electrode 201 and feeds the sampled current back to the control module 30. The voltage sampling circuit 37 is connected to the plasma electrode 201 to detect the voltage of the plasma electrode 201 and feeds the sampled voltage back to the control module 30. The control module 30 calculates based on these sampled current and voltage data to obtain the actual power of the plasma drive circuit in real time and compares it with preset power parameters, thereby realizing dynamic monitoring and power adjustment of the electric flame stove's operating status.

[0095] By providing real-time feedback on the current and voltage data of the plasma electrode 201, the control module 30 can determine the stability and safety of the plasma flame output and take timely control measures when abnormal power changes are detected, such as dynamically adjusting the output power or automatically cutting off the power, thereby effectively preventing potential safety hazards and ensuring the stable operation and safety protection of the electric flame stove under various working conditions.

[0096] Reference Figure 2 and Figure 3 As shown, in one embodiment of the present invention, the monitorable electric flame stove further includes a signal isolation controller 41. The first side of the signal isolation controller 41 is connected to the sampling signal output terminals of the current sampling circuit 36 ​​and the voltage sampling circuit 37, respectively. The second side of the signal isolation controller 41 is connected to the control module 30, so as to isolate and output the current sampling signal and / or voltage sampling signal to the control module 30.

[0097] The safe transmission of sampling signals is achieved through a signal isolation controller 41. By isolating the current and voltage sampling signals, the signal isolation controller 41 not only protects the control module 30 from interference from the high-voltage side but also prevents potential faults from damaging the front-end circuitry of the control module 30. This isolation output method can employ structures such as optocouplers to ensure the integrity and reliability of the sampling signals during transmission, thereby providing accurate data assurance for subsequent power monitoring and control. This not only enhances the anti-interference capability of the current and voltage sampling signals during transmission but also ensures that the control module 30 can obtain key data on the actual power of the plasma drive circuit in real time and accurately, greatly improving the safety monitoring performance and reliability of the electric flame stove.

[0098] Reference Figure 2 and Figure 3 As shown, in one embodiment of this utility model, the monitorable electric flame stove further includes a first power supply circuit 38 and a second power supply circuit 39. The transformer T1 includes a third coil T1C. The first power supply circuit 38 is connected to the third coil T1C to rectify, filter and stabilize the transformer output voltage of the third coil T1C, and then output a first DC power to power the control module 30 and the signal isolation controller 41.

[0099] The transformer T1 includes a fourth coil T1D. The second power supply circuit 39 is connected to the fourth coil T1D to rectify, filter and stabilize the output voltage of the fourth coil T1D, and then output a second DC power to power the signal isolation controller 41.

[0100] The first power supply circuit 38 supplies power to the front-end circuits such as the control module 30 and the signal isolation controller 41. The second power supply circuit 39 supplies power to the back-end circuits and the signal isolation controller 41. This enables separate power supply to the primary and secondary circuits of transformer T1, ensuring circuit stability.

[0101] Reference Figure 2 and Figure 8 As shown, in one embodiment of the present invention, the monitorable electric flame stove further includes a battery backup power supply circuit 42, which is used to provide emergency power to the control module 30, the positioning module 32 and the wireless communication module 33 when the AC input power is interrupted.

[0102] By configuring the battery backup power supply circuit 42, the electric flame stove can still ensure the monitoring of environmental data, the control of equipment safety status, and the real-time transmission of location information when the AC input power is interrupted, thereby ensuring the reliability of monitoring through a stable and reliable backup power supply.

[0103] Reference Figure 1As shown, in one embodiment of this utility model, the monitorable electric flame stove further includes a display module 202, which is connected to the control module 30 and is used to display the working status, power, usage time and location information of the electric flame stove.

[0104] The intuitive data display of the display module 202 improves the visual management of the equipment status and enables users and remote monitoring terminals 43 to monitor the operation of the electric flame stove in real time, thereby enhancing overall safety and user experience.
