[0028] Please refer to the wood chip combustion stove proposed in this utility model. Figure 1 and Figure 2 The wood chip combustion furnace includes a furnace body 10 and a feeding mechanism 20 connected to the furnace body 10. The furnace body 10 is equipped with a control panel 30 and a room temperature detection probe located inside the furnace body 10. The feeding mechanism 20 is equipped with a feeding motor 203, a push rod 202 rotatably connected to the feeding motor 203, and a material passage pipe 201. The push rod 202 is located in the material passage pipe 201, and the outlet of the material passage pipe 201 is connected to the combustion chamber 10a of the furnace body 10. The room temperature detection probe is fixedly located in the combustion chamber 10a of the furnace body 10 and is configured to detect the temperature of the combustion chamber 10a. The control panel 30 can receive the temperature of the combustion chamber 10a and drive the feeding motor 203 to rotate.

[0029] 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 203, thereby controlling the amount of movement of the combustion medium pushed by the push rod 202 through the feed pipe 201. 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 203 can be continuously driven to rotate so that the combustion chamber 10a enters the heating state.

[0030] The wood chip incinerator can be used indoors or outdoors for baking or roasting food. The incinerator body 10 includes a furnace body 10 and a cover. The cover is hinged to the furnace body 10 to enclose a combustion chamber 10a. During the heating process, the cover tightly closes the furnace 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 foods. It is understood that the combustion chamber 10a has an area where the combustion medium burns, 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 furnace body 10 and the cover.

[0031] 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 202. The feeding channel of the feeding pipe is connected to the combustion chamber 10a. The push rod 202 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 202. The stirring part extends along the axial direction of the push rod 202. Thus, as the solid combustion media enters the combustion chamber 10a along the feeding channel, the push rod 202, which is continuously rotated by the feeding motor 203, can be linked with the stirring part to 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 effect on the solid combustion media when rotating. As described above, the agitator extends along the axial direction of the push rod 202. In this way, the agitator can provide uniform agitation force along the entire length of the push rod 202, 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 202.

[0032] To controllably allow the solid combustion medium to enter 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 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 number of rotations of the feed motor 203 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 203 needs to rotate 50 times. Simultaneously, based on the structural parameters of the push rod 202, the feed motor 203 can... The solid combustion medium enters the combustion chamber 10a after the push rod 202 rotates 50 times, thereby raising the temperature of the combustion chamber 10a from 180F to 300F. It can be understood that, 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 push rod 202 pushing the solid combustion medium. At this time, the control panel 30 controls the feeding motor 203 to stop operating. Based on this, since 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 rotation of the feeding motor 203 according to the room temperature detection probe to keep the temperature of the combustion chamber 10a at the required temperature.

[0033] In one embodiment of this utility model, such as Figure 3As shown, 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 feed motor 203 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 203 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. Furthermore, 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.

[0034] 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 203 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 203 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 203's rotation, thereby achieving fine control of the temperature of the combustion chamber 10a.

[0035] Furthermore, such as Figure 3 As shown, and in combination Figure 4The control panel 30 also includes a first control button 33, and the controller 31 is further equipped 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 can be set to achieve 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, improve roasting efficiency, and increase temperature. The configuration of the temperature preset unit 312 ensures that the combustion chamber 10a does not exceed the safe temperature range, reducing potential risks during the baking process. Based on this, by precisely controlling the combustion temperature, unnecessary fuel consumption can be reduced, achieving the goal of energy conservation and environmental protection. Furthermore, 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 203. Thus, by pressing the feeding start / stop button 37, the working state of the feeding motor 203 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.

[0036] In one embodiment of this utility model, 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.

[0037] Furthermore, in one embodiment of this utility model, as Figure 3 As shown, and in combination Figure 4 The control panel 30 also includes a food temperature detection probe 35, which is movably mounted on the control panel 30 and electrically connected to the controller 31. The display module 32 also includes a meat temperature display screen, which is electrically connected to the controller 31. The meat temperature display screen is configured to display the temperature detected by the food temperature detection probe 35. Specifically, the control panel 30 has 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 temperature detected by the meat temperature display screen to determine the edibility of the food. It is understood that the food temperature detection probe 35 can be a wired probe or a wireless probe, which is not limited here.

[0038] Further, please refer to Figure 4The display module 32 is also equipped with a preset time display screen, and the controller 31 is also equipped 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, users 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 users 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.

[0039] 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.

[0040] In one embodiment of this utility model, such as Figure 3 As shown, and in combination Figure 4 The control panel 30 also includes a switching button 34, which is electrically connected to the timing unit 313 and the preset cavity temperature display. Specifically, by short-pressing the switching button 34, the temperature unit of the preset cavity temperature display and the cavity temperature display can be changed between Fahrenheit and Celsius; by long-pressing the switching button 34 for 3 seconds, the user can switch to the timing setting interface for setting and viewing the timing settings; by long-pressing the switching button 34 for 5 seconds, the user can turn the timing settings on / off. This effectively enhances the practicality of the wood chip combustion furnace and meets user needs.

[0041] Furthermore, the controller 31 also includes a frequency conversion switching unit, which is electrically connected to the feed motor 203 and the second control button 38. The frequency conversion switching unit is configured to control the current input value of the feed motor 203. 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 the first combustion state. In the first combustion state, the frequency conversion switching unit controls the feed motor 203 to be driven by the first current. At this time, the feed motor 203 rotates at a relatively slow first rotation speed, thereby controlling the speed at which the push rod pushes the wood chips into the combustion chamber. It can be understood that the first rotation speed can be pre-input in the controller. For example, in the first combustion state, the first rotation speed is [value missing]. The feed motor 203 rotates 10 times 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 203 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 203 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. It can be understood that the second rotation speed can be preset in the controller. For example, in the second combustion state, the first rotation speed is 20 rotations per minute for the feed motor 203, which is not limited here.

[0042] Furthermore, the controller 31 also includes a current detection unit and a motor reversing 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 reversing unit provided by the controller 31 starts to operate. That is, the reversing unit outputs a reversing current to the motor. Driven by this reversing current, the motor drives the push rod 202 to reverse, thereby causing the solid combustion medium to move backward, thus resolving the material jamming problem. It can be understood that the reversing current can be the maximum value of the feeding current threshold or any value within the feeding current threshold, and is not limited here.

[0043] Furthermore, in one embodiment of this utility model, the control panel 30 also includes a wireless module, which is 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. It is understood that the wireless module can be a Bluetooth module, a WIFI module, or both, and is not limited here.

[0044] Furthermore, the wood chip incinerator is 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. The wireless probe 36 is communicatively connected to the wireless module. The wireless module is configured to communicate with a smart terminal. Thus, users can monitor the working status of the wood chip incinerator in real time, such as heating time and chamber temperature, from a location away from the incinerator via mobile phones, tablets, or other devices, and remotely control the start and stop of the incinerator. At the same time, when using the wireless probe 36 to detect the temperature of food, users can also view the temperature of the food on the smart terminal using the communication function of the wireless module. It is understood that the wireless module can be a Bluetooth module, a WIFI module, or a combination of both, and is not limited here.

[0045] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
