[0038] The wood chip combustion furnace proposed in this application, as shown in Figures 1 and 2, includes a combustion furnace body 10 having a combustion chamber 10a and a feeding mechanism 20 connected to the combustion furnace body 10. The feeding mechanism 20 is provided with a feeding pipe 201 and a stirring rod 202. The feeding channel of the feeding pipe 201 is connected to the combustion chamber 10a. The stirring rod 202 is rotatably disposed in the feeding channel of the feeding pipe 201. The outer peripheral surface of the stirring rod 202 is provided with a stirring part 203, which extends along the axial direction of the stirring rod 202.

[0039] In this technical solution, the wood chip combustion furnace can use either small-diameter combustion particles or large-diameter wood chip fuel. Specifically, when the wood chip fuel is fed into the feeding pipe 201, the stirring rod 202 can rotate synchronously. During the rotation of the stirring rod 202, the protruding stirring part 203 of the stirring rod 202 can stir the wood chip fuel, thereby preventing the wood chip fuel from getting blocked in the feeding pipe 201 and causing a jamming problem. At the same time, the stirring part 203 extends along the axial direction of the stirring rod 202, which can push the wood chip fuel to move into the combustion chamber 10a, further preventing the jamming problem and thus ensuring heating efficiency.

[0040] The wood chip incinerator can be used indoors or outdoors for baking or roasting food. The incinerator body 10 includes a furnace body and a lid. The lid is hinged to the furnace body to enclose a combustion chamber 10a. During the heating process, the lid tightly closes the furnace body to create a sealed space within the combustion chamber 10a, thus preventing heat loss. Specifically, a grill rack or baking tray is provided in the combustion chamber 10a. The grill rack or baking tray can be screwed or inserted into screw holes or fixed at different heights, thereby adjusting its position within the combustion chamber 10a. The height of 0a is designed to provide suitable space for heating different ingredients. In the combustion chamber 10a, there is an area for the combustion medium to burn. The grill rack or baking tray is spaced apart from the combustion area. In this space, structures such as drip trays and heat-conducting plates can be placed to prevent dust from accumulating, heat from accumulating, and to collect oil. The heat generated by the combustion medium circulates in the combustion chamber 10a, thereby heating the food in the entire combustion chamber 10a. Of course, during the heating process, the heat will also flow to the outside through the furnace body and the cover.

[0041] To supplement the heat of the combustion chamber 10a, a feeding mechanism 20 is provided on one side of the combustion furnace body 10. The feeding mechanism 20 is responsible for conveying solid combustion media such as wood chips into the combustion chamber 10a. To prevent the solid combustion media from getting stuck during the conveying process, the feeding mechanism is equipped with a feeding pipe 201 and a stirring rod 202. The feeding channel of the feeding pipe 201 is connected to the combustion chamber 10a. The stirring rod 202 is rotatably mounted in the feeding channel of the feeding pipe 201. The outer circumferential surface of the stirring rod 202 is provided with a stirring part 203. The stirring part 203 moves along the stirring rod 202. Extending axially, the agitator 202, in conjunction with the agitator 203, pushes the solid combustion medium towards the combustion chamber 10a as it enters the combustion chamber 10a along the feeding channel. Specifically, the agitator 203 is wave-shaped, generating a pushing and pulling effect on the solid combustion medium during rotation, facilitating its smooth entry into the combustion chamber 10a. In another embodiment, the agitator 203 can be composed of a series of cylindrical protrusions, generating friction and pushing action on the solid combustion medium during rotation. Since the agitator 203 extends axially along the agitator 202, it provides uniform agitation force along the entire length of the agitator 202, ensuring even distribution of sawdust or other materials during transport, preventing accumulation or gaps. Furthermore, the continuous agitation action during transport keeps the solid combustion medium flowing, effectively preventing blockage within the agitator 202. The stirring rod 202 can be manually driven or motor driven, and there is no limitation here.

[0042] In one embodiment of this application, please refer to Figures 2 and 4, the stirring part 203 is a spiral protrusion.

[0043] In this embodiment, the stirring part 203 and the stirring rod 202 are an integral structure to prevent detachment. Specifically, the stirring part 203 is designed as a spiral protrusion. The spiral protrusion shape of the stirring part 203 can provide continuous rotational force during the stirring process, so that the solid combustion medium is continuously subjected to force during the stirring process, thereby maintaining continuous stirring and forward movement effects. At the same time, it helps the solid combustion medium to be evenly distributed during the stirring process, reducing the accumulation and gaps of the solid combustion medium around the stirring rod 202, ensuring the uniformity of the solid combustion medium dispersion, and thus avoiding material jamming. In one embodiment, to clarify the anti-jamming function of the spiral protrusion stirring part 203, the spiral direction of the stirring part 203 is defined as the first direction. In this case, the forward rotation of the stirring rod 202 can push the solid combustion medium forward. When a material jamming problem occurs, reversing the stirring rod 202 can drive the solid combustion medium backward, thereby solving the material jamming problem. How to determine if a solid combustion medium jamming problem occurs in the wood chip combustion furnace will be explained later.

[0044] In one embodiment of this application, please refer to Figures 4 and 5. The end of the stirring part 203 along the radial direction of the stirring rod 202 is provided with a stirring passage 20a on the inner wall of the feeding pipe 201.

[0045] In this embodiment, the radial direction of the stirring rod 202 is the same as the diameter direction of the stirring rod. The stirring part 203 protrudes from the outer surface of the stirring rod 202 along this direction. To prevent the large volume of solid combustion medium from getting stuck between the end of the stirring part 203 and the inner wall of the feeding pipe 201 during movement, a stirring channel 20a is formed between the end of the stirring part 203 and the inner wall of the feeding pipe 201. Thus, the feeding pipe 201 has sufficient space for the solid combustion medium to move during movement. In one embodiment, to facilitate the explanation of the benefits of the spiral protrusion stirring part 203 combined with the stirring channel 20a, it is defined that: the central axis of the stirring rod 202 is divided into any number of points along the axial direction (length direction). When the stirring part 203 is set as a spiral protrusion, there is only one stirring part 203 on both sides of each point along the radial direction. In this way, the space of the stirring channel 20a is expanded, and the flowability of the solid combustion medium in the feeding pipe 201 is enhanced.

[0046] In one embodiment of this application, please refer to FIG3, the feeding mechanism 20 further includes a feeding motor 204, the feeding motor 204 fixing the end of the feeding pipe 201 away from the combustion furnace body 10, and the stirring rod 202 connected to the rotating output shaft of the feeding motor 204.

[0047] In this embodiment, the feeding motor 204 is fixed at the end of the feeding pipe 201 away from the combustion furnace body 10, which can reduce the impact of heat on the electrical performance of the motor and extend the service life of the feeding motor 204. The feeding motor 204 drives the stirring rod 202 to rotate, avoiding the danger of manual rotation. Furthermore, by setting the output parameters of the feeding motor 204, the stirring rod 202 can rotate at a constant speed. In addition, an electronic control system can be set to control the start and stop of the feeding motor 204 in real time.

[0048] In one embodiment of this application, please refer to FIG3, the feeding mechanism 20 further includes a feeding funnel 205, which is fixedly connected to the outer side wall of the combustion furnace body 10; the feeding funnel 205 has a feed inlet and a discharge outlet connected to the feed inlet, and the discharge outlet is connected to the feeding channel of the feeding pipe 201.

[0049] In this embodiment, the discharge port at the lower end of the feeding funnel 205 is connected to the feeding channel of the feeding pipe 201, thereby achieving directional feeding. Simultaneously, the feeding funnel 205 provides a convenient inlet, allowing operators to easily add sawdust or other solid combustion media into the combustion furnace. Furthermore, the feeding funnel 205 can temporarily store a certain amount of fuel, ensuring that the combustion process is not affected even if feeding is stopped for a short period during continuous combustion. In one embodiment, a funnel cover is hinged to the feeding funnel 205 to cover the inlet, preventing rapid heat loss and ensuring the cleanliness of the funnel.

[0050] In one embodiment of this application, please refer to FIG3, the feeding mechanism 20 further includes a discharge assembly, which includes a discharge funnel 206 and a discharge baffle 207; the inlet of the discharge funnel 206 is connected to the material passage of the feeding funnel 205, and the discharge baffle 207 is slidably disposed at the inlet of the discharge funnel 206.

[0051] In this embodiment, the unloading funnel 206 is located on the side of the loading funnel 205. The inlet of the unloading funnel 206 is connected to the material passage of the loading funnel 205. The unloading baffle 207 is slidably disposed at the inlet of the unloading funnel 206. In this way, when the loading funnel 205 is blocked, the unloading baffle 207 is moved to connect the unloading funnel 206 with the loading funnel 205, providing an additional bypass passage for the loading funnel 205 to quickly clear the blockage and ensure the normal supply of fuel. At the same time, moving the unloading baffle 207 can quickly remove the unburned residual fuel. In order to realize the sliding of the unloading baffle 207, a chute structure is designed at the inlet of the unloading funnel 206, or a chute structure is formed between the unloading funnel 206 and the loading funnel 205, with the unloading baffle 207 located in the chute structure. In this way, the unloading baffle 207 can be pushed to move.

[0052] In one embodiment of this application, please refer to FIG3. The feeding mechanism 20 further includes a buffer net 208 and a vibrating assembly. The buffer net 208 is disposed at one end of the feeding funnel 205 near the inlet. The vibrating assembly includes a stirring motor 209 fixedly connected to the feeding funnel 205 and a vibrating rod 210 connected to the output end of the stirring motor 209. The vibrating end of the vibrating rod 210 is located between the buffer net 208 and the outlet.

[0053] In this embodiment, to prevent the solid combustion medium from directly impacting the feeding hopper 205 during feeding, a buffer net 208 is located at the end of the feeding hopper 205 near the inlet. Thus, the solid combustion medium first falls onto the buffer net 208, and after being buffered by the buffer net 208, it falls slowly into the feeding hopper 205. Simultaneously, from a safety perspective, the buffer net 208 prevents hands from entering, improving safety performance. In one embodiment, to prevent the buffered and decelerated solid combustion medium from causing jamming in the feeding hopper 205, a vibrating assembly is provided between the buffer net 208 and the outlet of the feeding hopper 205. The vibrating assembly includes a stirring motor 209 fixedly connected to the feeding hopper 205 and a vibrating rod 210 connected to the output end of the stirring motor 209. Thus, during feeding, the stirring motor 209 drives the vibrating rod 210 to vibrate, thereby preventing the solid combustion medium from concentrating in the feeding hopper 205 and clogging the outlet.

[0054] In one embodiment of this application, please refer to Figures 2, 4 and 5. The combustion furnace body 10 is provided with a fire pot 101 in the combustion chamber 10a. The combustion space of the fire pot 101 is connected to the feeding channel of the feeding pipe 201. The outer peripheral wall of the fire pot 101 is provided with a plurality of air dampers 101a, and each air damper 101a is arranged at intervals along the outer peripheral wall of the fire pot 101.

[0055] In this embodiment, the fire pot 101 serves as the combustion zone of the combustion chamber 10a. The fire pot 101 is fixed to the sheet metal parts inside the combustion chamber 10a by disc screws. Thus, after one batch of food has been roasted, the fire pot 101 can be removed by unscrewing the disc screws, thereby removing the combustion ash from the fire pot 101 for cleaning purposes. The side wall of the fire pot 101 has a docking hole, and the discharge end of the feeding pipe 201 is fixedly connected to the docking hole of the fire pot 101, so that the combustion space of the fire pot 101 is connected to the feeding channel of the feeding pipe 201. In one embodiment, in order to improve the combustion efficiency of the solid combustion medium, the outer peripheral wall of the fire pot 101 is provided with multiple air dampers 101a. Each air damper 101a is spaced along the outer peripheral wall of the fire pot 101. By setting the air dampers 101a, the combustion space of the fire pot 101 and the air supply channel of the wood chip combustion furnace can be connected to enhance gas flow and improve combustion efficiency.

[0056] In one embodiment of this application, please refer to FIG1. ​​The wood chip combustion furnace is further provided with a control panel 30, which is configured to control the combustion temperature of the combustion chamber 10a.

[0057] In this embodiment, the control panel 30 includes a display module, a temperature detection port, and control buttons. By pressing different control buttons, the heating temperature, heating time, and pause time of the wood chip combustion oven can be set, thereby allowing different heating treatments to be applied to different ingredients to ensure the flavor of each food. At the same time, the temperature detection port of the control panel 30 allows a temperature probe (temperature sensor) to be inserted to detect the temperature of the combustion chamber 10a. Furthermore, the display module can display the temperature of the combustion chamber 10a, the heating temperature, the heating time, and the pause time, etc. By setting the control panel 30, precise control of the combustion temperature can be achieved, thereby optimizing the cooking experience. Specifically, in this technical solution, a room temperature detection probe is fixedly installed in the combustion chamber 10a. The room temperature detection probe is electrically connected to the control panel 30. The control panel 30 receives the detected temperature from the room temperature detection probe and controls the number of rotations of the feeding motor 204, thereby controlling the amount of movement of the combustion medium pushed by the stirring rod 202 through the feed tube 201a. In this way, it is effectively avoided that when too much material is added, all the combustion medium will enter the combustion chamber 10a, avoiding the problem of food burning due to excessively high temperature in the combustion chamber 10a. Similarly, when the detected chamber temperature is too low, the feeding motor 204 can be continuously driven to rotate, so that the combustion chamber 10a enters the heating state.

[0058] The room temperature detection probe can provide real-time feedback of the chamber temperature to the control panel 30. The control panel 30 controls the number of rotations of the feeding motor 204 based on the chamber temperature. For example, if the maximum limit temperature of the wood chip combustion furnace is set to 300°F (Fahrenheit), the controller 31 knows that the real-time temperature of the combustion chamber 10a is 180°F (Fahrenheit) based on the temperature feedback from the room temperature detection probe. The control program presets that for every 1°F difference, the feeding motor 204 needs to rotate 50 times. At the same time, based on the structural parameters of the stirring rod 202, it can be determined that the solid combustion medium enters the combustion chamber 10a after the stirring rod 202 rotates 50 times. The combustion chamber 10a is heated from 180°F to 300°F. Because the room temperature detection probe detects the temperature of the combustion chamber 10a in real time, the temperature of the combustion chamber 10a reaches the maximum limit temperature during the process of the stirring rod 202 pushing the solid combustion medium. At this time, the control panel 30 controls the feeding motor 204 to stop. Based on this, because the heat of the wood chip combustion furnace is always in a state of loss, when the wood chip combustion furnace is in operation, the control panel 30 can always control the feeding motor 204 to rotate according to the room temperature detection probe so that the temperature of the combustion chamber 10a is at the required temperature.

[0059] In one embodiment of this application, as shown in FIG7, the control panel 30 includes a controller 31 and a display module 32. The display module 32 is equipped with a chamber temperature display screen, which is electrically connected to the controller 31. The controller 31 is configured to receive the detected temperature from the room temperature detection probe and drive the feeding motor 204 to rotate. The chamber temperature display screen is configured to display the detected temperature from the room temperature detection probe. Thus, by receiving real-time temperature data from the room temperature detection probe through the controller 31, the rotation of the feeding motor 204 can be precisely controlled, thereby accurately adjusting the temperature within the combustion chamber 10a, which helps maintain the stability and efficiency of the combustion process. In one embodiment, the chamber temperature display screen in the display module 32 can intuitively display the current temperature, allowing users to easily monitor and adjust the combustion process, thus improving the user experience.

[0060] Specifically, the controller 31 is equipped with a temperature detection unit 311, and the chamber temperature display screen is electrically connected to the temperature detection unit 311. The temperature detection unit 311 is configured to receive the detected temperature from the room temperature detection probe and drive the feeding motor 204 to rotate. By integrating the temperature detection unit 311 into the controller 31, integrated temperature monitoring and management are achieved. This integrated design simplifies the system structure, reduces the connection points between components, and thus reduces the failure rate. At the same time, the temperature detection unit 311 directly receives the signal from the room temperature detection probe and drives the feeding motor 204 to rotate. This direct response mechanism can adjust the temperature of the combustion chamber 10a more quickly, improving the system's response speed and efficiency. Based on this, the temperature detection unit 311 can accurately read the temperature data of the probe, ensuring the accuracy of the rotation of the feeding motor 204, thereby achieving fine control of the temperature of the combustion chamber 10a.

[0061] In one embodiment, as shown in Figure 7 and in conjunction with Figure 8, the control panel 30 further includes a first control button 33, and the controller 31 is also provided with a temperature preset unit 312. The first control button 33 is electrically connected to the temperature preset unit 312. The temperature preset unit 312 is configured to set the maximum temperature of the combustion chamber 10a, and the first control button 33 is configured to adjust the maximum temperature of the combustion chamber 10a. The first control button 33 includes an up button and a down button, and different triggering methods are set to realize temperature setting, such as short press to increase or decrease and long press to continuously increase or decrease. This is not limited here. By quickly adjusting the maximum temperature of the combustion chamber 10a, the user can more effectively control the roasting process of the wood chip combustion oven and improve roasting efficiency. The configuration of the temperature preset unit 312 ensures that the combustion chamber 10a will not exceed the safe temperature range, reducing the possible risks during the roasting process. Based on this, by accurately controlling the combustion temperature, unnecessary fuel consumption can be reduced, achieving the purpose of energy saving and environmental protection. In one embodiment, the control panel 30 further includes a feeding start / stop button 37, which is electrically connected to the controller 31. The feeding start / stop button 37 is configured to control the start and stop of the feeding motor 203a. Thus, by pressing the feeding start / stop button 37, the working state of the feeding motor 203a can be manually controlled, thereby controlling the amount of combustion medium conveyed. At the same time, the feeding method can be forcibly stopped to improve safety performance.

[0062] In one embodiment of this application, the display module 32 is further provided with a preset cavity temperature display screen, which is electrically connected to the temperature preset unit 312. The preset cavity temperature display screen is configured to display the maximum temperature of the set combustion chamber 10a. In this way, the user can clearly know the current safe temperature limit of the combustion chamber 10a, which helps to prevent overheating. By setting the cavity temperature display screen and the preset cavity temperature display screen, the roasting visualization of the wood chip combustion oven can be enhanced.

[0063] In one embodiment of this application, as shown in FIG7 and in conjunction with FIG8, the control panel 30 further includes a food temperature detection probe 35, which is movably disposed on the control panel 30 and electrically connected to the controller 31; the display module 32 is further provided with a meat temperature display screen, which is electrically connected to the controller 31; the meat temperature display screen is configured to display the detection temperature of the food temperature detection probe 35. Specifically, the control panel 30 is provided with a probe socket for placing the food temperature detection probe 35. When it is necessary to determine whether the food is cooked through and safe to eat after a certain period of time, the user opens the cover, inserts the food temperature detection probe 35 into the food, and then reads the detection temperature on the meat temperature display screen to determine the edibility of the food; the food temperature detection probe 35 can be a wired probe or a wireless probe, which is not limited here.

[0064] In one embodiment, referring to Figure 8, the display module 32 is further provided with a preset time display screen, and the controller 31 is further provided with a timing unit 313. The preset time display screen and the first control button 33 are electrically connected to the timing unit 313. The first control button 33 is also configured to set the heating time of the oven body 10, and the preset time display screen is configured to display the set heating time of the oven body 10. In this way, the user can set different heating times for different ingredients through the first control button 33 to ensure the taste of different foods. At the same time, the preset time display screen allows the user to know their heating time, so as to use the gap in the heating time of the ingredients to prepare other ingredients or prepare for the meal.

[0065] In one embodiment, the display module 32 is further provided with a countdown time display screen, and the controller 31 is further provided with a timing unit 314, which is electrically connected to the timing unit 313. The countdown time display screen is configured to display the remaining time of the set heating time of the oven body 10. Thus, the user sets the heating time of the oven body 10 through the first control button 33, the timing unit 313 receives these settings, and then the timing unit 314 starts when heating begins and begins the countdown. The countdown time display screen displays the remaining time calculated by the timing unit 314, allowing the user to know the baking progress at any time. When the timing unit 314 reaches zero, the controller 31 can perform a preset operation, such as turning off the heating, thereby completing the baking process. After baking is completed, the user can use the food temperature detection probe 35 to detect the food temperature, thereby deciding whether to reheat or bake the next ingredient.

[0066] In one embodiment of this application, as shown in FIG7 and in conjunction with FIG8, the control panel 30 further includes a switching button 34. The switching button 34 is electrically connected to the timing unit 313 and the preset cavity temperature display screen. Specifically, by short-pressing the switching button 34, the temperature unit of the preset cavity temperature display screen and the cavity temperature display screen can be changed between Fahrenheit (F) and Celsius (C); by long-pressing the switching button 34 for 3 seconds, the timer setting interface can be switched to for timer setting and viewing; by long-pressing the switching button 34 for 5 seconds, the timer setting can be turned on / off. In this way, the practicality of the wood chip combustion furnace is effectively enhanced, meeting user needs.

[0067] In one embodiment of this application, the control panel 30 further includes a wireless module electrically connected to the controller 31. The wireless module is configured to communicate with a smart terminal, so that users can view the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, and remotely control the start and stop of the wood chip incinerator from a location far away from the incinerator via a mobile phone, tablet computer, or other device. The wireless module can be a Bluetooth module, a WIFI module, or both, and is not limited here.

[0068] In one embodiment, the controller 31 further includes a frequency conversion switching unit electrically connected to the feeding motor 203a and the second control button 38. The frequency conversion switching unit is configured to control the current input value of the feeding motor 203a. Specifically, when the wood chip combustion furnace uses wood chips as the combustion source, and the wood chips are relatively large, in order to facilitate the control of the temperature of the combustion chamber, the second control button 38 is pressed to control the frequency conversion switching unit to make the wood chip combustion furnace enter a first combustion state. In the first combustion state, the frequency conversion switching unit controls the feeding motor 203a to be driven by a first current. At this time, the feeding motor 203a rotates at a slower first rotation speed, thereby controlling the speed at which the push rod 202a pushes the wood chips into the combustion chamber. The first rotation speed can be pre-input in the controller, for example, in the first combustion state, the first rotation speed is... The feed motor 203a rotates 10 revolutions per minute, which is not limited here. If pellet fuel is required as the combustion source, and the pellet fuel is small in size, in order to quickly heat up the combustion chamber, press the second control button 38 to control the switching frequency converter to make the wood chip combustion furnace enter the second combustion state. In the second combustion state, the switching frequency converter controls the feed motor 203a to be driven by a second current. At this time, the value of the second current is greater than the value of the first current, and the feed motor 203a rotates at a faster second rotation speed. The second rotation speed is greater than the first rotation speed, thereby accelerating the speed at which the push rod 202a pushes the pellet fuel into the combustion chamber. The second rotation speed can be preset in the controller. For example, in the second combustion state, the first rotation speed is 20 revolutions per minute for the feed motor 203a, which is not limited here.

[0069] In one embodiment, the controller 31 further includes a current detection unit and a motor reversal unit. The current detection unit is configured to detect the motor current output value. The wood chip combustion furnace determines whether a material jamming problem has occurred based on the magnitude of the motor's output current. Specifically, the controller 31 sets a feeding current threshold. The current detection unit detects the motor's output current value in real time. When the current detection unit detects that the output current value is less than the feeding current threshold, it generates a corresponding judgment signal (material jamming signal). The controller 31 determines that a material jamming problem has occurred in the wood chip combustion furnace based on this signal. At this time, the motor reversal unit provided by the controller 31 starts to operate. That is, the reversal unit outputs a reversal current to the motor. Driven by this reversal current, the motor drives the push rod 202a to reverse, thereby causing the solid combustion medium to move backward, thus resolving the material jamming problem. The reversal current can be the maximum value of the feeding current threshold or any value within the feeding current threshold, and is not limited here.

[0070] In one embodiment of this application, the control panel 30 further includes a wireless module electrically connected to the controller 31. The wireless module is configured to communicate with a smart terminal, so that users can view the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, and remotely control the start and stop of the wood chip incinerator from a location far away from the incinerator via a mobile phone, tablet computer, or other device. The wireless module can be a Bluetooth module, a WIFI module, or both, and is not limited here.

[0071] In one embodiment, the wood chip incinerator is further equipped with a wireless probe 36 on the control panel. The control panel 30 also includes a wireless module, which is electrically connected to the controller 31, and the wireless probe 36 is communicatively connected to the wireless module. The wireless module is configured to communicate with a smart terminal, so that users can view the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, from a location away from the wood chip incinerator via a mobile phone, tablet, or other device, and remotely control the start and stop of the wood chip incinerator. At the same time, when using the wireless probe 36 to detect the temperature of food, the user can also view the temperature of the food on the smart terminal using the communication function of the wireless module. The wireless module can be a Bluetooth module, a WIFI module, or a combination of both, and is not limited here.

[0072] In one embodiment of this application, please refer to FIG6, the combustion furnace body 10 is further provided with a heat preservation chamber 40 and a side platform extension 50. The heat preservation chamber 40 is located at the lower part of the combustion chamber 10a; the side platform extension 50 is located on the side of the combustion furnace body 10 opposite to the feeding mechanism 20.

[0073] In this embodiment, the heat preservation chamber 40 is located at the lower part of the combustion chamber 10a. The heat preservation chamber 40 contains multiple heating tubes and a heating griddle. The cooked food can be placed on the heating griddle within the heat preservation chamber 40. When the heating tubes are powered on, they continuously heat the food, thus preventing it from cooling down. In one embodiment, a side platform extension 50 is provided on one side of the combustion furnace body 10 opposite to the feeding mechanism 20. In one embodiment, the side platform extension 50 has multiple hooks for placing an oil collection container. In another embodiment, the side platform extension 50 is composed of multiple sheet metal parts, and a gas furnace is placed inside. A frying pan can be placed on the upper part of the side platform extension 50. The combustion chamber 10 is rotatably connected via a hinged structure, allowing for folding and storage. When using the wood chip combustion stove, the user can prepare other foods on a griddle while working in the combustion chamber 10a, thus improving food processing efficiency. Specifically, please refer to Figures 9-14. The side platform extension 50 is the second furnace body. Each furnace body has a combustion space, allowing multiple foods or various types of foods to be heated simultaneously. The second furnace body includes a second combustion chamber 51, a gas placement chamber 52, and an ignition device 53. The gas placement chamber 52 is located below the second combustion chamber 51 and is used to hold a gas canister. The gas outlet of the ignition device 53 is connected to the... The combustion space 50a of the second combustion chamber 51 is connected to the gas cylinder in the gas placement chamber 52 via the outlet of the ignition device 53. Based on this, the gas entering the combustion space 50a can be ignited by the ignition device 53 for heating food. The second combustion chamber 51 and the gas placement chamber 52 are formed by multiple sheet metal parts, enclosing independent spaces. The ignition device 53 includes a rotary knob, a solenoid valve, a gas pipe, a main burner tube, and an electric coupler. The two ends of the solenoid valve are connected to a gas pipe, forming the inlet and outlet (injector tube 58) of the ignition device 53. The main burner tube and the electric coupler are electrically connected to the solenoid valve, controlling the rotation of the knob to generate an electric spark in the electric coupler. The ignition device 53 ignites the gas coming out of the main burner tube. Specifically, the gas outlet of the ignition device 53 is connected to the combustion space 50a of the second combustion chamber 51. The gas outlet of the ignition device 53 can be connected to the gas canister in the gas placement chamber 52. The ignition ends of the main burner tube and the electric thermocouple rod face the combustion space 50a, thus realizing the baking function of the second furnace body. The second combustion chamber 51 and the gas placement chamber 52 of the second furnace body are distributed vertically. The gas placement chamber 52 is located below the second combustion chamber 51 and is used to place the gas canister. At the bottom of the gas placement chamber 52, there is a limiting hole, and the gas canister seat is placed in the limiting hole to prevent the gas canister from becoming loose in the second furnace body.

[0074] In one embodiment, the second combustion chamber 51 is provided with a heat spreader 54, which divides the combustion chamber of the second combustion chamber 51 to form a baking space 50b and a combustion space 50a. Specifically, the gas outlet of the ignition device 53 (i.e., the gas outlet pipe connected to the solenoid valve) is located in the combustion space 50a, while the food is placed in the baking space 50b. The combustion space 50a and the baking space 50b are isolated by the heat spreader 54. In this way, the heat from the combustion space 50a is evenly transferred to the baking space 50b through the heat spreader 54, avoiding uneven heating of the food. The heat spreader 54 is made of ceramic material, which can withstand high temperatures and will not deform or be damaged during high-temperature cooking. It also has good thermal conductivity, which can effectively transfer heat and ensure the uniformity of food heating. The material of the heat spreader 54 can also be stainless steel, cast iron, etc., and is not limited here.

[0075] To achieve a sealed baking effect, the wood chip combustion oven also includes a second cover 55, which is hinged to the second combustion chamber 51 via a hinge structure, thereby enabling the opening and closing of the second cover 55 and the second oven body.

[0076] In one embodiment of this application, the wood chip combustion oven also includes a side oven 56, which is vertically and vertically mounted in the baking space 50b. By adjusting the height of the side oven 56 in the baking space 50b, the distance between the food and the heat spreader 54 can be changed to avoid direct contact with high temperatures. On the other hand, it provides sufficient space for food of different shapes to be placed in the baking space 50b. The side oven 56 includes, but is not limited to, structures such as grill racks and grill pans, and is not limited here.

[0077] Specifically, the hot pot grill 56 includes a support portion 561 and a support leg 562. The support portion 561 is used to place food, and the support leg 562 is used for support and fixation. The support leg 562 includes an integral first support segment 5621 and a second support segment 5622. The first support segment 5621 is connected to the support portion 561, and the cross-sectional dimension of the first support segment 5621 is larger than the cross-sectional dimension of the second support segment 5622. The grilling space 50b is provided with a first insertion hole 50b1 adapted to the first support segment 5621 and a second insertion hole 50b2 adapted to the second support segment 5622. The first support segment 5621 is positioned close to the second socket 50b2. When food needs to be moved closer to the combustion space 50a, the second support segment 5622 is inserted into the second socket 50b2. At the same time, the cross-sectional dimension of the first support segment 5621 is larger than the cross-sectional dimension of the second socket 50b2. The first support segment 5621 abuts against the periphery of the second socket 50b2, thereby achieving support and fixation. When food needs to be moved away from the combustion space 50a, the support leg 562 is inserted into the first socket 50b1. The first support segment 5621 is locked in the first socket 50b1, thereby achieving support and fixation.

[0078] In one embodiment, to prevent heat from concentrating at the outlet end of the ejector tube 58 of the ignition device 53 in the combustion space 50a, a diffusion net 57 is provided in the combustion space 50a. The diffusion net 57 is aligned with the outlet end of the ignition device 53. Thus, when the gas comes out from the outlet end, it comes into contact with the diffusion net 57 immediately. Under the action of the surface tension of the diffusion net 57, the gas is dispersed along the diffusion net 57 into the combustion space 50a, thereby ensuring the uniformity of combustion in the combustion space 50a. At the same time, the porous structure on the diffusion net 57 can prevent backfire. The diffusion net 57 can be a metal plate structure or a ceramic material, which is not limited here.

[0079] In one embodiment of this application, the wood chip combustion oven also includes a heat preservation box 60, which is located below the combustion oven body 10. In this way, the cooked food can be placed in the heat preservation box 60 to keep it warm and prevent it from getting cold when placed outside. The heat preservation box 60 has a closed structure. In order to facilitate the display of the internal structure of the heat preservation box 60, image processing has been performed.

[0080] In one embodiment, the insulated box 60 is provided with a plurality of insulated nets 61, which are spaced apart along the height of the insulated box 60 to provide sufficient space for food of different shapes to be placed in the baking space 50b.

[0081] In one embodiment of this application, the heat preservation box 60 is provided with a heating tube 62, which is positioned away from any heat preservation net. In this way, the heating tube 62 can provide real-time heat replenishment to the heat preservation box 60 through its heating effect, which can prevent the heat of the heat preservation box 60 from being lost to the outside and causing the indoor temperature to drop.

[0082] Please refer to Figures 6 and 9-11. The wood chip incinerator includes a first furnace body 100 and a first furnace cover. The first furnace cover is hinged to the first furnace body 100 and encloses it to form a first combustion chamber. The wood chip incinerator also includes a second furnace body 200, which is located on one side of the first furnace body 100. The second furnace body 200 includes a second combustion chamber 51, a gas placement chamber 52, and an ignition device 53. The ignition device 53 is located in the second combustion chamber 51, and the gas placement chamber 52 is located below the second combustion chamber 51 and is used to place a gas canister. The gas outlet of the ignition device 53 is connected to the combustion space 50a of the second combustion chamber 51, and the gas outlet of the ignition device 53 can be connected to the gas canister in the gas placement chamber 52.

[0083] In this technical solution, the wood chip combustion oven includes a first oven body 100 and a second oven body 200. Each oven body has a combustion space 50a, so that multiple foods or various foods can be heated simultaneously. Specifically, the second oven body 200 includes a second combustion chamber 51, a gas placement chamber 52, and an ignition device 53. The gas placement chamber 52 is located below the second combustion chamber 51 and is used to place a gas canister. The gas outlet of the ignition device 53 is connected to the combustion space 50a of the second combustion chamber 51, and the gas outlet of the ignition device 53 can be connected to the gas canister in the gas placement chamber 52. Based on this, the gas entering the combustion space 50a can be ignited by the ignition device 53 to provide heat for heating food.

[0084] The wood chip incinerator can be used indoors or outdoors for baking or roasting food. The main body of the wood chip incinerator consists of a first furnace body 100 and a first furnace lid. The first furnace lid is hinged to the first furnace body 100 and encloses a first combustion chamber. During the heating process, the first furnace lid tightly closes the first furnace body 100 to create a sealed space within the first combustion chamber, thus preventing heat loss. Specifically, a grilling rack or baking tray is provided in the first combustion chamber. The grilling rack or baking tray can be screwed or inserted into screw holes or fixed in places of different heights to change its height within the first combustion chamber, providing suitable space for heating different ingredients. The first combustion chamber has an area where the combustion medium burns, and to prevent the grilling rack or baking tray from directly contacting the open flame, there is a certain distance between the grilling rack or baking tray and the combustion area. The heat generated by the combustion medium circulates within the first combustion chamber, heating the food throughout the chamber. Of course, during the heating process, some heat also flows to the outside through the furnace body and lid.

[0085] In one embodiment, to improve the roasting efficiency of the wood chip combustion furnace, an additional roasting area is provided on one side of the first furnace body 100. Specifically, the wood chip combustion furnace includes a second furnace body 200, which is located on one side of the first furnace body 100. The second furnace body 200 includes a second combustion chamber 51, a gas placement chamber 52, and an ignition device 53. The second combustion chamber 51 and the gas placement chamber 52 are formed by multiple sheet metal parts and enclose each other to form independent spaces. The ignition device 53 includes a rotary knob, a solenoid valve, a gas pipe, a main flame tube, and an electric coupler. The two ends of the solenoid valve are respectively connected to a gas pipe, forming the gas inlet and gas outlet (ejector tube 58) of the ignition device 53. The main flame tube and the electric coupler are electrically connected to the solenoid valve. The rotary knob is controlled to generate an electric spark in the electric coupler, thereby igniting the gas coming out of the main flame tube. Specifically, the gas outlet of the ignition device 53 is connected to the second combustion chamber 51. The combustion space 50a of the chamber 51 has an outlet end of the ignition device 53 that can be connected to the gas canister in the gas placement chamber 52. The ignition ends of the mother flame tube and the thermocouple rod face the combustion space 50a, thus enabling the baking function of the second furnace body 200. The combustion chamber of the second combustion chamber 51 is independent of the first combustion chamber, and the two can be used independently. The ignition devices 53 of the first furnace body 100 and the second furnace body 200 are also independently set. The first furnace body 100 mainly burns sawdust, charcoal particles, etc., while the second furnace body 200 burns combustible gases such as natural gas and coal gas. The second combustion chamber 51 and the gas placement chamber 52 of the second furnace body 200 are distributed vertically. The gas placement chamber 52 is located below the second combustion chamber 51 and is used to place the gas canister. At the bottom of the gas placement chamber 52, there is a limiting hole, and the gas canister seat is placed in the limiting hole to prevent the gas canister from becoming loose in the second furnace body 200.

[0086] In one embodiment, referring to Figure 11, the second combustion chamber 51 is provided with a heat spreader 54. The heat spreader 54 divides the combustion chamber of the second combustion chamber 51 so that the combustion chamber forms a baking space 50b and a combustion space 50a. Specifically, the gas outlet of the ignition device 53 (i.e., the gas outlet pipe connected to the solenoid valve) is located in the combustion space 50a, while the food is placed in the baking space 50b. The combustion space 50a and the baking space 50b are isolated by the heat spreader 54. In this way, the heat from the combustion space 50a is evenly transferred to the baking space 50b through the heat spreader 54, avoiding uneven heating of the food.

[0087] In one embodiment of this application, the heat spreader 54 is made of ceramic. The ceramic heat spreader 54 can withstand high temperatures and will not deform or be damaged during high-temperature cooking. At the same time, it has good thermal conductivity and can effectively transfer heat to ensure the uniformity of food heating. The heat spreader 54 can also be made of stainless steel, cast iron, etc., and is not limited here.

[0088] To achieve a sealed baking effect, please refer to Figure 11. The wood chip combustion oven also includes a second cover 55, which is hinged to the second combustion chamber 51 via a hinge structure, thereby enabling the opening and closing of the second cover 55 and the second oven body 200.

[0089] In one embodiment of this application, please refer to Figure 11. The wood chip combustion oven also includes a side oven 56. The side oven 56 is vertically mounted in the baking space 50b. By adjusting the height of the side oven 56 in the baking space 50b, the distance between the food and the heat spreader 54 can be changed to avoid direct contact with high temperature. On the other hand, it can also provide sufficient space for food of different shapes to be placed in the baking space 50b. The side oven 56 includes, but is not limited to, structures such as grill racks and grill pans, and is not limited here.

[0090] Specifically, please refer to Figures 12 to 14. The sideboard grill 56 includes a support portion 561 and a support leg 562. The support portion 561 is used to place food, and the support leg 562 is used for support and fixation. The support leg 562 includes an integral first support segment 5621 and a second support segment 5622. The first support segment 5621 is connected to the support portion 561, and the cross-sectional dimension of the first support segment 5621 is larger than the cross-sectional dimension of the second support segment 5622. The grilling space 50b is provided with a first insertion hole 50b1 adapted to the first support segment 5621 and a second insertion hole 50b2 adapted to the second support segment 5622. The first insertion hole 50b1 is positioned close to the second insertion hole 50b2. Therefore, when the food needs to be brought close to the combustion space 50a, the second support segment 5622 is inserted into the second socket 50b2, and the cross-sectional dimension of the first support segment 5621 is larger than the cross-sectional dimension of the second socket 50b2. The first support segment 5621 abuts against the periphery of the second socket 50b2 to achieve support and fixation. When the food needs to be moved away from the combustion space 50a, the support leg 562 is inserted into the first socket 50b1, and the first support segment 5621 is locked in the first socket 50b1 to achieve support and fixation. The first socket 50b1 and the second socket 50b2 can be circular holes, square holes, or holes of any shape, and are not limited here.

[0091] Please refer to Figure 11. To prevent heat from concentrating at the outlet end of the injector tube 58 of the ignition device 53 in the combustion space 50a, a diffuser net 57 is provided in the combustion space 50a. The diffuser net 57 is aligned with the outlet end of the ignition device 53. In this way, after the gas comes out from the outlet end, it comes into contact with the diffuser net 57 immediately. Under the action of the surface tension of the diffuser net 57, the gas is dispersed along the diffuser net 57 into the combustion space 50a, thereby ensuring the uniformity of combustion in the combustion space 50a. At the same time, the porous structure on the diffuser net 57 can prevent backfire. The diffuser net 57 can be made of metal plate or ceramic material, which is not limited here.

[0092] In one embodiment of this application, please refer to Figures 1-3. The wood chip combustion oven also includes a heat preservation box 60, which is located below the first oven body 100. In this way, the cooked food can be placed in the heat preservation box 60 to keep it warm and prevent it from getting cold when placed outside. The heat preservation box 60 has a closed structure. In order to make it easier to show the internal structure of the heat preservation box 60, image processing has been performed.

[0093] In one embodiment, please refer to Figure 2. The insulated box 60 is provided with a plurality of insulated nets 61, which are spaced apart along the height of the insulated box 60 to ensure that food of different shapes has sufficient space to be placed in the baking space 50b.

[0094] In one embodiment of this application, please refer to Figure 2. The heat preservation box 60 is provided with a heating tube 62. The heating tube 62 is provided with a heating wire that is electrically connected to the power supply of the wood chip combustion furnace. The heating tube 62 is positioned away from any heat preservation net. In this way, the heat preservation box 60 can be replenished with heat in real time through the heating effect of the heating tube 62, which can prevent the heat of the heat preservation box 60 from being lost to the outside and the indoor temperature from dropping.

[0095] The wood chip combustion furnace proposed in this application, as shown in Figures 1 and 2, includes a combustion furnace body 10 and a feeding mechanism 20 connected to the combustion furnace body 10. The combustion furnace body 10 is equipped with a control panel 30 and a room temperature detection probe located inside the combustion furnace body 10. The feeding mechanism 20 is equipped with a feeding motor 203a, a push rod 202a rotatably connected to the feeding motor 203a, and a feed pipe 201a. The push rod 202a is located in the feed pipe 201a, and the outlet of the feed pipe 201a is connected to the combustion chamber 10a of the combustion furnace body 10. The room temperature detection probe is fixedly located in the combustion chamber 10a of the combustion furnace body 10 and is configured to detect the temperature of the combustion chamber 10a. The control panel 30 is capable of receiving the temperature of the combustion chamber 10a and driving the feeding motor 203a to rotate.

[0096] In this technical solution, a room temperature detection probe is fixedly installed in the combustion chamber 10a of the wood chip combustion furnace body 10. The room temperature detection probe is electrically connected to the control panel 30. The control panel 30 receives the detected temperature from the room temperature detection probe and controls the number of rotations of the feeding motor 203a, thereby controlling the amount of movement of the combustion medium in the feed pipe 201a by the push rod 202a. In this way, it is effectively avoided that when too much material is added, all the combustion medium will enter the combustion chamber 10a, avoiding the problem of food burning due to excessive temperature in the combustion chamber 10a. Similarly, when the detected chamber temperature is too low, the feeding motor 203a can be continuously driven to rotate so that the combustion chamber 10a enters the heating state.

[0097] The wood chip incinerator can be used indoors or outdoors for baking or roasting food. The incinerator body 10 includes an incinerator body 10 and a cover. The cover is hinged to the incinerator body 10 to enclose a combustion chamber 10a. During the heating process, the cover tightly closes the incinerator body 10 to create a sealed space in the combustion chamber 10a, thus preventing heat loss. Specifically, a grill rack or baking tray is provided in the combustion chamber 10a. The grill rack or baking tray can be screwed or inserted into screw holes or fixed at different heights to change its height in the combustion chamber 10a, providing suitable space for heating different ingredients. The combustion chamber 10a has an area for the combustion medium to burn, and to prevent the grill rack or baking tray from directly contacting the open flame, there is a certain distance between the grill rack or baking tray and the combustion area. The heat generated by the combustion medium circulates in the combustion chamber 10a, thereby heating the food in the entire combustion chamber 10a. Of course, during the heating process, the heat will also flow to the outside through the incinerator body 10 and the cover.

[0098] To supplement the heat of the combustion chamber 10a, a feeding mechanism 20 is provided on one side of the combustion furnace body 10. The feeding mechanism 20 is responsible for conveying solid combustion media such as wood chips into the combustion chamber 10a. Specifically, the feeding mechanism 20 is provided with a feeding pipe and a push rod 202a. The feeding channel of the feeding pipe is connected to the combustion chamber 10a. The push rod 202a is rotatably disposed in the feeding channel of the feeding pipe. A spiral-shaped stirring part is protruding from the outer peripheral surface of the push rod 202a. The stirring part extends along the axial direction of the push rod 202a. Thus, as the solid combustion media enters the combustion chamber 10a along the feeding channel, the continuously rotating push rod 202a, in conjunction with the stirring part, can push the solid combustion media toward the combustion chamber 10a. In another embodiment, the stirring part can be composed of a series of cylindrical protrusions, so that the stirring part generates friction and pushing action on the solid combustion media when rotating. As described above, the agitator extends along the axial direction of the push rod 202a. In this way, the agitator can provide uniform agitation force along the entire length of the push rod 202a, ensuring that wood chips or other materials are evenly distributed during the conveying process, avoiding accumulation or gaps. Furthermore, during the transportation process, the agitation action can continuously act on the solid combustion medium, keeping the solid combustion medium flowing and effectively preventing the solid combustion medium from clogging inside the push rod 202a.

[0099] To controllably introduce the solid combustion medium into the combustion chamber 10a, a room temperature detection probe is installed inside the combustion chamber 10a. This probe is electrically connected to the control panel 30 of the combustion furnace body 10. Thus, the room temperature detection probe can provide real-time feedback of the chamber temperature to the control panel 30. The control panel 30 controls the rotation number of the feed motor 203a based on the chamber temperature. For example, if the maximum temperature limit of the wood chip combustion furnace is set to 300°F (Fahrenheit), and the temperature feedback from the room temperature detection probe indicates that the real-time temperature of the combustion chamber 10a is 180°F (Fahrenheit), the control program presets that for every 1°F difference, the feed motor 203a needs to rotate 50 times. Simultaneously, based on the structure of the push rod 202a… The parameters determine that after the push rod 202a rotates 50 times, the solid combustion medium enters the combustion chamber 10a, thereby raising the temperature of the combustion chamber 10a from 180F to 300F. Because the room temperature detection probe detects the temperature of the combustion chamber 10a in real time, when the push rod 202a pushes the solid combustion medium, the temperature of the combustion chamber 10a reaches the maximum limit temperature. At this time, the control panel 30 controls the feeding motor 203a to stop. Based on this, since the heat of the wood chip combustion furnace is always being lost, when the wood chip combustion furnace is in operation, the control panel 30 can always control the feeding motor 203a to rotate according to the room temperature detection probe to keep the temperature of the combustion chamber 10a at the required temperature.

[0100] In one embodiment of this application, as shown in FIG7, the control panel 30 includes a controller 31 and a display module 32. The display module 32 is provided with a chamber temperature display screen, which is electrically connected to the controller 31. The controller 31 is configured to receive the detected temperature from the room temperature detection probe and drive the feed motor 203a to rotate. The chamber temperature display screen is configured to display the detected temperature from the room temperature detection probe. Thus, by receiving real-time temperature data from the room temperature detection probe through the controller 31, the rotation of the feed motor 203a can be precisely controlled, thereby accurately adjusting the temperature inside the combustion chamber 10a, which helps to maintain the stability and efficiency of the combustion process. In one embodiment, the chamber temperature display screen in the display module 32 can intuitively display the current temperature, allowing users to easily monitor and adjust the combustion process, thus improving the user experience.

[0101] Specifically, the controller 31 is equipped with a temperature detection unit 311, and the chamber temperature display screen is electrically connected to the temperature detection unit 311. The temperature detection unit 311 is configured to receive the detected temperature from the room temperature detection probe and drive the feed motor 203a to rotate. By integrating the temperature detection unit 311 into the controller 31, integrated temperature monitoring and management are achieved. This integrated design simplifies the system structure, reduces the connection points between components, and thus reduces the failure rate. At the same time, the temperature detection unit 311 directly receives the signal from the room temperature detection probe and drives the feed motor 203a to rotate. This direct response mechanism can adjust the temperature of the combustion chamber 10a more quickly, improving the system's response speed and efficiency. Based on this, the temperature detection unit 311 can accurately read the probe's temperature data, ensuring the accuracy of the feed motor 203a's rotation, thereby achieving fine control of the temperature of the combustion chamber 10a.

[0102] In one embodiment, as shown in FIG7 and in conjunction with FIG8, the control panel 30 further includes a first control button 33, and the controller 31 is further provided with a temperature preset unit 312. The first control button 33 is electrically connected to the temperature preset unit 312. The temperature preset unit 312 is configured to set the maximum temperature of the combustion chamber 10a, and the first control button 33 is configured to adjust the maximum temperature of the combustion chamber 10a. The first control button 33 includes an up button and a down button, and different triggering methods are set to realize temperature setting, such as short press to increase or decrease and long press to continuously increase or decrease. No limitation is made here. By quickly adjusting the maximum temperature of the combustion chamber 10a, the user can more effectively control the roasting process of the wood chip combustion oven, improving efficiency and efficiency. The high baking efficiency and the configuration of the temperature preset unit 312 ensure that the combustion chamber 10a does not exceed the safe temperature range, reducing the potential risks during baking. Based on this, by precisely controlling the combustion temperature, unnecessary fuel consumption can be reduced, achieving the goal of energy conservation and environmental protection. In one embodiment, the control panel 30 also includes a feeding start / stop button 37, which is electrically connected to the controller 31. The feeding start / stop button 37 is configured to control the start and stop of the feeding motor 203a. Thus, by pressing the feeding start / stop button 37, the working state of the feeding motor 203a can be manually controlled, thereby controlling the amount of combustion medium delivered. At the same time, the feeding method can be forcibly stopped, thereby improving safety performance.

[0103] In one embodiment of this application, the display module 32 is further provided with a preset cavity temperature display screen, which is electrically connected to the temperature preset unit 312. The preset cavity temperature display screen is configured to display the maximum temperature of the set combustion chamber 10a. In this way, the user can clearly know the current safe temperature limit of the combustion chamber 10a, which helps to prevent overheating. By setting the cavity temperature display screen and the preset cavity temperature display screen, the roasting visualization of the wood chip combustion oven can be enhanced.

[0104] In one embodiment of this application, as shown in FIG7 and in conjunction with FIG8, the control panel 30 further includes a food temperature detection probe 35, which is movably disposed on the control panel 30 and electrically connected to the controller 31; the display module 32 is further provided with a meat temperature display screen, which is electrically connected to the controller 31; the meat temperature display screen is configured to display the detection temperature of the food temperature detection probe 35. Specifically, the control panel 30 is provided with a probe socket for placing the food temperature detection probe 35. When it is necessary to determine whether the food is cooked through and safe to eat after a certain period of time, the user opens the cover, inserts the food temperature detection probe 35 into the food, and then reads the detection temperature on the meat temperature display screen to determine the edibility of the food; the food temperature detection probe 35 can be a wired probe or a wireless probe, which is not limited here.

[0105] In one embodiment, referring to Figure 8, the display module 32 is further provided with a preset time display screen, and the controller 31 is further provided with a timing unit 313. The preset time display screen and the first control button 33 are electrically connected to the timing unit 313. The first control button 33 is also configured to set the heating time of the combustion furnace body 10, and the preset time display screen is configured to display the set heating time of the combustion furnace body 10. In this way, the user can set different heating times for different ingredients through the first control button 33 to ensure the taste of different foods. At the same time, the preset time display screen allows the user to know their heating time, so as to use the gap in the heating time of the ingredients to prepare other ingredients or prepare for the meal.

[0106] In one embodiment, the display module 32 is further provided with a countdown time display screen, and the controller 31 is further provided with a timing unit 314, which is electrically connected to the timing unit 313. The countdown time display screen is configured to display the remaining time of the set heating time of the combustion oven 10. Thus, the user sets the heating time of the combustion oven 10 through the first control button 33, the timing unit 313 receives these settings, and then the timing unit 314 starts when heating begins and begins the countdown. The countdown time display screen displays the remaining time calculated by the timing unit 314, allowing the user to know the baking progress at any time. When the timing unit 314 reaches zero, the controller 31 can perform a preset operation, such as turning off the heating, thereby completing the baking process. After baking is completed, the user can use the food temperature detection probe 35 to detect the food temperature, thereby deciding whether to reheat or bake the next ingredient.

[0107] In one embodiment of this application, as shown in FIG7 and in conjunction with FIG8, the control panel 30 further includes a switching button 34. The switching button 34 is electrically connected to the timing unit 313 and the preset cavity temperature display screen. Specifically, by short-pressing the switching button 34, the temperature unit of the preset cavity temperature display screen and the cavity temperature display screen can be changed between Fahrenheit (F) and Celsius (C); by long-pressing the switching button 34 for 3 seconds, the timer setting interface can be switched to for timer setting and viewing; by long-pressing the switching button 34 for 5 seconds, the timer setting can be turned on / off. In this way, the practicality of the wood chip combustion furnace is effectively enhanced, meeting user needs.

[0108] In one embodiment, the controller 31 further includes a frequency conversion switching unit electrically connected to the feeding motor 203a and the second control button 38. The frequency conversion switching unit is configured to control the current input value of the feeding motor 203a. Specifically, when the wood chip combustion furnace uses wood chips as the combustion source, and the wood chips are relatively large, in order to facilitate the control of the temperature of the combustion chamber, pressing the second control button 38 controls the frequency conversion switching unit to make the wood chip combustion furnace enter a first combustion state. In the first combustion state, the frequency conversion switching unit controls the feeding motor 203a to be driven by a first current. At this time, the feeding motor 203a rotates at a slower first rotation speed, thereby controlling the speed at which the push rod pushes the wood chips into the combustion chamber. The first rotation speed can be pre-input in the controller, for example, in the first combustion state, the first rotation speed is... The feed motor 203a rotates 10 revolutions per minute, which is not limited here. If pellet fuel is required as the combustion source, and the pellet fuel is small in size, in order to quickly heat up the combustion chamber, press the second control button 38 to control the switching frequency converter to make the wood chip combustion furnace enter the second combustion state. In the second combustion state, the switching frequency converter controls the feed motor 203a to be driven by a second current. At this time, the value of the second current is greater than the value of the first current, and the feed motor 203a rotates at a faster second rotation speed. The second rotation speed is greater than the first rotation speed, thereby accelerating the speed at which the push rod pushes the pellet fuel into the combustion chamber. The second rotation speed can be preset in the controller. For example, in the second combustion state, the first rotation speed is 20 revolutions per minute for the feed motor 203a, which is not limited here.

[0109] In one embodiment, the controller 31 further includes a current detection unit and a motor reversal unit. The current detection unit is configured to detect the motor current output value. The wood chip combustion furnace determines whether a material jamming problem has occurred based on the magnitude of the motor's output current. Specifically, the controller 31 sets a feeding current threshold. The current detection unit detects the motor's output current value in real time. When the current detection unit detects that the output current value is less than the feeding current threshold, it generates a corresponding judgment signal (material jamming signal). The controller 31 determines that a material jamming problem has occurred in the wood chip combustion furnace based on this signal. At this time, the motor reversal unit provided by the controller 31 starts to operate. That is, the reversal unit outputs a reversal current to the motor. Driven by this reversal current, the motor drives the push rod 202a to reverse, thereby causing the solid combustion medium to move backward, thus resolving the material jamming problem. The reversal current can be the maximum value of the feeding current threshold or any value within the feeding current threshold, and is not limited here.

[0110] In one embodiment of this application, the control panel 30 further includes a wireless module electrically connected to the controller 31. The wireless module is configured to communicate with a smart terminal, so that users can view the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, and remotely control the start and stop of the wood chip incinerator from a location far away from the incinerator via a mobile phone, tablet computer, or other device. The wireless module can be a Bluetooth module, a WIFI module, or both, and is not limited here.

[0111] In one embodiment, the wood chip incinerator is further equipped with a wireless probe 36 on the control panel. The control panel 30 also includes a wireless module, which is electrically connected to the controller 31, and the wireless probe 36 is communicatively connected to the wireless module. The wireless module is configured to communicate with a smart terminal, so that users can view the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, from a location away from the wood chip incinerator via a mobile phone, tablet, or other device, and remotely control the start and stop of the wood chip incinerator. At the same time, when using the wireless probe 36 to detect the temperature of food, the user can also view the temperature of the food on the smart terminal using the communication function of the wireless module. The wireless module can be a Bluetooth module, a WIFI module, or a combination of both, and is not limited here.
