[0053] like Figures 1 to 7 As shown, the utility model provides a heating device 100, including a main body 110, an electric furnace module 120 and a charcoal furnace module 130. It should be noted that the heating device 100 provided by the utility model can be applied to the scenario of boiling tea around a stove, and the electric furnace mode and the charcoal furnace mode can be switched according to different usage scenarios. For example, when the user needs to take the heating device 100 outdoors for activities such as picnics or outings, the heating device 100 can be switched to the charcoal furnace mode. When the user uses the heating device 100 indoors or in an environment that is not suitable for charcoal fire, the heating device 100 can be switched to the electric furnace mode. It should also be noted that the electric furnace module 120 can be heated by infrared, halogen lamp or far infrared, and the charcoal furnace module 130 can be heated by charcoal or other fuels.

[0054] Specifically, Figure 1-Figure 5As shown, the body 110 has a receiving cavity 111, the electric furnace module 120 is detachably connected to the receiving cavity 111, and the charcoal furnace module 130 is detachably connected to the receiving cavity 111. The charcoal furnace module 130 is provided with a receiving space 131, and at least part of the electric furnace module 120 can be received in the receiving space 131, so that the electric furnace module 120 is detachably connected to the charcoal furnace module 130. In this way, when the user needs to take the heating device 100 outdoors, the electric furnace module 120 can be placed in the charcoal furnace module 130 for easy carrying.

[0055] The heating device 100 is switchable between an electric stove mode and a charcoal stove mode. In the electric stove mode, the electric stove module 120 is installed in the accommodating cavity 111, and food can be placed on the electric stove module 120 to heat the food.

[0056] In the charcoal stove mode, the charcoal stove module 130 is installed in the accommodating cavity 111 , so that the user can place charcoal fire in the charcoal stove module 130 to heat food.

[0057] In this way, during outdoor activities, users can make full use of the characteristics of charcoal fire and enjoy the unique flavor and atmosphere that charcoal fire brings to food; while in indoor environments, the electric stove mode can provide a safer and more convenient heating option, avoiding the potential safety hazards and ventilation problems that may be caused by using charcoal fire in a closed space.

[0058] According to the heating device 100 provided by the utility model, by providing a housing space 131 in the charcoal stove module 130, at least part of the electric stove module 120 can be accommodated in the housing space 131, so that the electric stove module 120 is detachably connected to the charcoal stove module 130. In this way, when the user needs to take the heating device 100 outdoors, the electric stove module 120 can be placed in the charcoal stove module 130, which is convenient to carry and reduces the occupied space. In addition, when the heating device 100 is not in use, the electric stove module 120 is placed in the housing space 131 of the charcoal stove module 130, which can effectively protect the electric stove module 120 from damage by the external environment, such as bumps, dust and moisture.

[0059] In some examples of the present invention, an electric socket can be provided on the electric furnace module 120, and a plug can be provided on the peripheral wall of the accommodating cavity 111. When the electric furnace module 120 is installed in the accommodating cavity 111, the electric socket and the plug can be matched to make the electric furnace module 120 and the body 110 electrically connected, thereby avoiding cumbersome operations and improving user experience. Alternatively, in other examples, the electric furnace module 120 can also be electrically connected to the body 110 by wireless charging, making installation and removal simpler and more intuitive.

[0060] like Figure 3 and Figure 4As shown, in some embodiments of the utility model, the heating device 100 includes a fan 150, and the fan 150 is connected to the control module so that the control module can control the wind speed of the fan 150. The fan 150 is installed in the body 110, and the airflow generated by the fan 150 flows into the accommodating chamber 111, so that the airflow in the accommodating chamber 111 flows. Among them, the surrounding wall of the charcoal stove module 130 is provided with ventilation holes. When the heating device 100 is in the charcoal stove mode, the airflow generated by the fan 150 can control the size of the charcoal fire in the charcoal stove module 130. For example, when the charcoal fire needs to be larger, the airflow generated by the fan 150 can be made larger, and when the charcoal fire needs to be smaller, the airflow generated by the fan 150 can be made smaller. In addition, the airflow provided by the fan 150 can promote the full combustion of the charcoal fire, improve the combustion efficiency, and reduce the smoke emission of the charcoal fire, making it more environmentally friendly and efficient during use.

[0061] When the heating device 100 is in the electric furnace mode, the airflow generated by the fan 150 can dissipate heat for the electric furnace module 120. The airflow generated by the fan 150 can promptly take away the heat generated by the electric furnace module 120 to prevent the electric furnace module 120 and the body 110 from overheating, thereby reducing wear and damage to the equipment and extending the service life of the electric furnace module 120. In addition, the improvement in the heat dissipation effect allows the electric furnace module 120 to maintain stable performance during long-term use, avoiding performance degradation or failure due to overheating. The fan 150 uniformly manages the heat dissipation and oxygen enrichment requirements in the electric furnace and charcoal furnace modes, making system maintenance and operation simple and efficient.

[0062] In some embodiments of the utility model, the body is further provided with a control module. In the electric stove mode, the electric stove module 120 is installed in the accommodating cavity 111 and connected to the control module. Food can be placed on the electric stove module 120 to heat the food. In this way, when the user switches the heating device 100 to the electric stove mode, the temperature of the electric stove module 120 can be directly controlled by the control module provided on the body 110, or the opening and closing of the electric stove module 120 can be controlled, making it more convenient for the user to operate and improving the user experience.

[0063] like Figure 1-Figure 7As shown, in some embodiments of the utility model, the control module includes a control rod 112, the control rod 112 at least partially extends from the body 110, and the control rod 112 is electrically connected to the fan 150 to control the wind speed of the fan 150. Among them, the control rod 112 can be designed as a multi-gear, providing different wind speed options, so as to meet the different needs of users for wind speed in different heating modes and cooking stages. In this way, during the cooking process, the user can adjust the wind speed at any time as needed, control the firepower in real time, ensure that the food is heated evenly, and achieve the ideal cooking effect. In addition, by adjusting the fan 150 through the control rod 112, the user does not need to directly contact the hot charcoal basin or the fan 150, which reduces the risk of scalding and increases the safety of operation. In addition, when the user needs to turn on or off the fan 150, the opening and closing of the fan 150 can also be controlled by the control rod 112.

[0064] Of course, the form of the control module is not limited to this. In some other embodiments of the present invention, the control module may also include a control panel (not shown in the figure) arranged on the main body 110. The user can adjust the temperature of the electric furnace module 120, the opening and closing of the electric furnace module 120, the wind speed of the fan 150, etc. through the control panel, so as to facilitate the user to control and adjust the heating equipment to meet the different cooking needs of the user.

[0065] like Figure 4 As shown, in some embodiments of the utility model, the fan 150 includes a first fan 151 and a second fan 152 arranged in parallel. In the electric furnace mode, the first fan 151 is turned off and the second fan 152 is started to dissipate heat for the electric furnace module 120. In the charcoal furnace mode, the first fan 151 is started to supply air and increase oxygen for the charcoal furnace, and the second fan 152 is turned off to save energy. Among them, the second fan 152 can be specially designed for the heat dissipation of the electric furnace module 120, so that its working parameters and wind output are optimized to meet the heat dissipation requirements of the electric furnace module 120, ensuring that the electric furnace module 120 is maintained within a safe temperature range.

[0066] like Figure 3 As shown, in some embodiments of the present invention, the body 110 includes an outer shell 113, an inner liner 114 and a heat dissipation channel 115. The inner liner 114 is arranged in the outer shell 113, and the inner liner 114 forms a receiving cavity 111. The heat dissipation channel 115 is arranged between the outer shell 113 and the inner liner 114, so that the heat generated by the entire heating device 100 when working can be effectively dissipated through the channel to avoid local overheating. The fan 150 is arranged in the heat dissipation channel 115, which can more effectively promote the flow of air and make the airflow in the heat dissipation channel 115 smooth. Therefore, the heat dissipation channel 115 can assist the fan 150 in heat dissipation and improve the heat dissipation efficiency.

[0067] like Figure 3As shown, in some embodiments of the utility model, a vent 116 is provided at the bottom of the accommodating cavity 111, the vent 116 is connected to the heat dissipation channel 115, and the fan 150 is arranged opposite to the vent 116. In this way, it can be ensured that the airflow enters from the bottom of the accommodating cavity 111 and enters the heat dissipation channel 115 through the vent 116, forming a natural convection from bottom to top, thereby improving the heat dissipation efficiency. The fan 150 is arranged opposite to the vent 116, directly pushing the airflow through the vent 116 into the heat dissipation channel 115, effectively enhancing the airflow power, accelerating the flow speed of the airflow in the heat dissipation channel 115, taking away more heat, and enhancing the overall heat dissipation effect.

[0068] In the electric stove mode, the fan 150 pushes the airflow through the vents 116 into the heat dissipation channel 115, effectively taking away the heat generated by the electric stove module 120 to prevent the device from overheating. In the charcoal stove mode, the fan 150 provides sufficient oxygen to the charcoal fire through the vents 116 to promote the full combustion of the charcoal fire. At the same time, the heat dissipation channel 115 effectively discharges the waste gas and heat generated by the burning of the charcoal fire, thereby improving safety and use effect.

[0069] like Figure 3 As shown, in some embodiments of the utility model, the body 110 also has a heat collection space 117, which is arranged at the top of the body 110, and the heat collection space 117 is connected to the accommodating cavity 111, and the opening area of ​​the heat collection space 117 is larger than the opening area of ​​the accommodating cavity 111, so that it is convenient for the user to put the charcoal stove module 130 or the electric stove module 120 into or out of the accommodating cavity 111, and the possibility of misoperation or collision in the process of putting the charcoal stove module 130 or the electric stove module 120 into or out of the accommodating cavity 111 is reduced, and the safety and accuracy of the operation are improved. In addition, the wall surface of the heat collection space 117 is a concave surface, and the concave structure allows the heat energy to be concentrated and reflected, which helps to more effectively concentrate the heat in the heat collection space 117, improve the heating efficiency, shorten the time for the heating device 100 to reach the target temperature, reduce the waiting time of the user, and improve the convenience of use.

[0070] like Figure 3 As shown, in some embodiments of the present invention, the wall surface of the heat collection space 117 forms an overlap surface 1171, and the electric furnace module 120 or the charcoal furnace module 130 is connected to the overlap surface 1171. In this way, the electric furnace module 120 or the charcoal furnace module 130 can be stably suspended in the heat collection space 117, and the electric furnace module 120 or the charcoal furnace module 130 can avoid tilting or moving during use, ensuring the safety and stability of the cooking process. In addition, the support design of the overlap surface 1171 can prevent the electric furnace module 120 or the charcoal furnace module 130 from directly contacting the bottom wall of the accommodating cavity 111, which can effectively prevent the module from overheating, avoid heat accumulation caused by direct contact, improve the heat dissipation effect, and reduce the damage to the equipment that may be caused by high temperature or vibration.

[0071] The charcoal stove module 130 has a first overlap portion 132, which is connected to the overlap surface 1171 in the charcoal stove mode. The electric stove module 120 has a second overlap portion 121, which is connected to the overlap surface 1171 in the electric stove mode.

[0072] In some embodiments of the present invention, the overlapping surface 1171 can be designed with anti-slip texture or anti-slip device to further enhance the stability of the connection between the electric furnace module 120 or the charcoal furnace module 130 and prevent the electric furnace module 120 or the charcoal furnace module 130 from moving or sliding during operation.

[0073] like Figure 7 As shown, in some embodiments of the present invention, the electric furnace module 120 has a second overlapping portion 121 , and the second overlapping portion 121 can be overlapped with the charcoal furnace module 130 . The height of the electric furnace module 120 is lower than that of the charcoal furnace module 130 .

[0074] like Figure 7 As shown, in some embodiments of the present invention, the area of ​​the space enclosed by the first overlapping portion 132 is S1, the area enclosed by the second overlapping portion 121 is S2, the opening area of ​​the heat collecting space 117 is S3, the opening area of ​​the accommodating cavity 111 is S4, and the opening area of ​​the accommodating space 131 is S5, S3>S1>S2>S4>S5.

[0075] like Figure 3 and Figure 6 As shown, in some embodiments of the utility model, the body 110 has a recessed handle 118, which is convenient for users to grasp and carry the heating device 100, reducing the risk of accidental drop of the heating device 100 during transportation. In addition, the body 110 also includes a carrying strap 119, which is provided with a buckle 1191, and the buckle 1191 is detachably connected to the handle 118, which is convenient for users to carry the heating device 100 in different scenarios, suitable for outdoor activities such as picnics, camping, etc. Users can conveniently carry the entire set of heating devices 100 through the carrying strap 119.

[0076] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the heating device 100 further includes a cover 160, which is disposed on the body 110 and corresponds to the accommodating cavity 111. When the heating device 100 is not in use, the cover 160 can prevent dust and debris from entering the accommodating cavity 111, thereby keeping the heating device 100 clean. In addition, the cover 160 can also prevent external debris from accidentally colliding with or damaging the interior of the device, thereby protecting internal components.

[0077] like Figure 5As shown, in some embodiments of the utility model, the heating device 100 also includes a baking tray 170. When the heating device 100 is in the charcoal stove mode, the baking tray 170 can be mounted on the charcoal basin, so that the heating device 100 can realize frying and grilling functions in the charcoal stove mode, thereby meeting the user's diverse cooking needs in the wild or outdoor activities.

[0078] In some embodiments of the utility model, the main body 110 also has a USB port, which is connected to the control module 140. When the user uses the heating device 100 outdoors, the main body 110 can be powered by a power bank or other device, thereby increasing the convenience of use.

[0079] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
