[0030] Embodiment 1:

[0031] Attached Figure 1 To Attachment Figure 3 As shown, it is a schematic diagram of a first embodiment of a temperature-adjustable outdoor air fryer provided by the present invention. The air fryer includes a shell 10 and a hot air circulation system 20 arranged in the shell 10. A cooking cavity 11 for holding food is provided in the shell 10, and the cooking cavity 11 is suitable for being connected to the hot air circulation system 20.

[0032] like Figure 3As shown, the cooking cavity 11 is provided with an external circulation duct 12, and the external circulation duct 12 is preferably arranged around the cooking cavity 11; a heat source 30 is provided inside the external circulation duct 12, and the heat source 30 is suitable for heat transfer with the outer wall of the cooking cavity 11, and the heat source 30 is a related heat source affected by oxygen content, preferably coal, charcoal, alcohol, gas stove or wood. The heat source 30 is suitable for burning and generating heat to heat the air in the cooking cavity 11, and the hot air circulation system 20 is suitable for driving the hot air flow in the cooking cavity 11 to generate a circulating heat flow to heat the food in the cooking cavity 11. Choosing coal, charcoal, alcohol, gas stove or wood as the heat source is easy to carry on the one hand, and has a wide range of access and low cost on the other hand, which can effectively improve the practicality of the air fryer product.

[0033] like Figure 2 and Figure 3 As shown, a control system 40 and a drive motor 50 are further disposed in the housing 10 . The drive motor 50 is adapted to be electrically connected to the control system 40 , and the control system 40 is adapted to control the operation of the drive motor 50 .

[0034] like Figure 3 As shown, the housing 11 is provided with a vent 13 , and the vent 13 is connected to the external circulation air duct 12 , and external air is suitable to flow into the external circulation air duct 12 through the vent 13 to contact the heat source 30 to promote the combustion of the heat source 30 .

[0035] like Figure 3 As shown, a temperature-controlled fan 14 is provided in the external circulation air duct 12, and the temperature-controlled fan 14 is connected to the driving motor 50. The temperature-controlled fan 14 is suitable for rotating under the drive of the driving motor 50 to control the air flow in the external circulation air duct 12. External air is suitable for entering the external circulation air duct 12 through the vent 13 under the action of the temperature-controlled fan 14 and contacting the heat source 30.

[0036] In the air fryer, the driving motor 50 is preferably a speed-regulating motor, and the adjustable speed characteristic of the driving motor 50 can cooperate with the temperature-controlled fan 14 to adjust the amount and speed of external air entering the external circulation duct 12 through the vent 13 .

[0037] like Figure 2 and Figure 3As shown, the housing 10 is further provided with a temperature sensor 15 electrically connected to the control system 40. The temperature sensor 15 is adapted to extend into the cooking cavity 11. The temperature sensor 15 is adapted to measure the temperature in the cooking cavity 11 and feed back to the control system 40. The control system 40 is adapted to control and adjust the rotation speed of the drive motor 50. Different preset temperatures are provided in the control system 40 for different foods. When the control system 40 receives the feedback temperature from the temperature sensor 15, it is adapted to compare it with the optimal cooking temperature. When the feedback temperature from the temperature sensor 15 is higher than the optimal cooking temperature, the control system 40 is adapted to control the drive motor 50 to reduce the rotation speed so as to reduce the amount and speed of external air entering the external circulation air duct 12, thereby reducing the combustion speed of the heat source 30 and the temperature in the cooking cavity 11. When the feedback temperature from the temperature sensor 15 is lower than the optimal cooking temperature, the control system 40 is adapted to control the drive motor 50 to increase the rotation speed so as to increase the amount and speed of external air entering the external circulation air duct 12, thereby increasing the combustion speed of the heat source 30 and the temperature in the cooking cavity 11. The air fryer can automatically adjust the temperature in the cooking cavity 11 by arranging the heat source 30 affected by the oxygen content in the external circulation air duct 12, and arranging the control system 40 and the driving motor 50 and the temperature sensor 15 that cooperate with each other in the shell 10, so that the temperature in the cooking cavity 11 is maintained at the optimal cooking temperature, thereby effectively improving the cooking effect of the air fryer.

[0038] like Figure 3 As shown, a control chamber 16 is provided in the outer shell 10, and the control chamber 16 is located outside the outer circulation air duct 12. The control system 40 and the drive motor 50 are provided in the control chamber 16; a heat insulation plate 17 is provided between the control chamber 16 and the outer circulation air duct 12, and the periphery of the heat insulation plate 17 is suitable for extending outward and abutting against the inner wall of the outer shell 10, and the heat insulation plate 17 is suitable for separating the control chamber 16 from the outer circulation air duct 12 to prevent the heat flow in the outer circulation air duct 12 from flowing into the control chamber 16 and damaging the control system 40 and the drive motor 50 in the control chamber 16.

[0039] like Figure 3As shown, the vent 13 includes an air inlet 131 and an air outlet 132, and the air inlet 131 and the air outlet 132 are respectively located at two ends of the external circulation air duct 12. The external air is suitable for entering the external circulation air duct 12 from the air inlet 131 under the action of the temperature control fan 14 and contacting the heat source 30 to promote the combustion of the heat source 30. The hot air heated by the heat source 30 in the external circulation air duct 12 and the flame retardant generated by the combustion of the heat source 30 are suitable for being discharged through the air outlet 132 under the action of the temperature control fan 14.

[0040] like Figure 3 As shown, the air inlet 131 is preferably arranged adjacent to the heat source 30, and the air outlet 132 is preferably arranged adjacent to the temperature control fan 14. By arranging the air inlet 131 adjacent to the heat source 30, when external air enters the external circulation air duct 12 through the air inlet 131, oxygen in the air can quickly contact with the heat source 30, thereby promoting the combustion of the heat source 30 and achieving rapid heating. At the same time, by arranging the temperature control fan 14 adjacent to the air outlet 132, the heat flow in the external circulation air duct 12 can be quickly discharged, thereby achieving rapid cooling.

[0041] like Figures 1 to 3 As shown, the air inlet 131 is preferably arranged at the bottom of the housing 10. The air inlet 131 is arranged at the bottom of the housing 10 to hide the air inlet 131, thereby improving the overall aesthetics of the air fryer. The bottom of the housing 10 is also provided with a support foot 18 extending downward. The support foot 18 is preferably formed integrally with the housing 10. The support foot 18 is suitable for suspending the housing 10 to reserve enough space at the bottom of the housing 10 for air circulation, so as to ensure that the external air can smoothly enter the external circulation duct 12 through the air inlet 131, thereby ensuring normal cooking.

[0042] like Figures 1 to 3 As shown, a chassis 60 is detachably provided at the bottom of the shell 10, and the shell 10 is suitable for being suspended on the chassis 60 through the supporting feet 18. When used outdoors, the chassis 60 is suitable for providing a stable supporting surface for the air fryer to prevent the air fryer from being unable to cook normally due to the working surface. The chassis 60 effectively ensures the normal operation of the air fryer when used outdoors, thereby improving the applicability of the air fryer.

[0043] like Figures 1 to 3As shown, the bottom plate 60 has a storage cavity 61 with an open top, and the housing 10 is suitable for being suspended in the storage cavity 61. When the air fryer is in use, the bottom plate 60 can be used in conjunction with the housing 10 to support and bear the air fryer, or can be used alone to store kitchen waste, items, etc. using the storage cavity 61, thereby effectively improving the practicality of the air fryer.

[0044] like Figure 2 and Figure 3 As shown, a fryer 70 is detachably disposed in the housing 10, the fryer 70 has a food placement cavity 71 with an open top, a food tray or a food basket is disposed in the food placement cavity 71, the outer wall of the fryer 70 at least partially constitutes the outer wall of the cooking cavity 11, and the heat source 30 is suitable for being sandwiched between the fryer 70 and the housing 10. The fryer 70 is detachably disposed in the housing 10, and the heat source 30 is sandwiched between the housing 10 and the fryer 70, which is not only convenient for taking and placing the cooked food, but also convenient for replacing the heat source 30, thereby improving the convenience of using the air fryer.

[0045] like Figure 1 and Figure 2 As shown, a handle 72 is provided on the side or top of the fryer 70 , and the handle 72 is suitable for holding. The fryer 70 can be moved or disassembled by the handle 72 , and the handle 72 effectively reduces the difficulty of operating the fryer 70 .

[0046] like Figure 3 As shown, the heat source 30 is detachably disposed in the circulation duct 12 at the side and / or below the cooking cavity 11, and cooperates with the outer wall of the cooking cavity 11 in heat transfer. The heat source 30 is detachably disposed in the circulation duct 12 at the side and / or below the cooking cavity 11, which not only enables the heat source 30 to better cooperate with the outer wall of the cooking cavity 11 in heat transfer, but also enables the replacement of the heat source 30 to ensure normal cooking.

[0047] Embodiment 2:

[0048] As attached Figure 4 and attached Figure 5 As shown, it is a schematic diagram of a second embodiment of a temperature-adjustable outdoor air fryer provided by the present invention. Compared with the air fryer in the first embodiment, the air fryer in the second embodiment has some identical structural features and working principles, which will not be described herein. The difference between the second embodiment and the first embodiment is the positions of the air inlet and the air outlet and the path of the airflow in the external circulation air duct.

[0049] like Figure 5As shown, in the second embodiment, a control chamber 16A is provided in the outer shell 10A, and the control chamber 16A is located outside the outer circulation air duct 12A, and the control system 40A and the drive motor 50A are provided in the control chamber 16A; a heat insulation plate 17A is provided between the control chamber 16A and the outer circulation air duct 12A, and the periphery of the heat insulation plate 17A is suitable for extending outward and abutting against the inner wall of the outer shell 10A, and a connecting port 171A for connecting the outer circulation air duct 12A and the control chamber 16A is provided on the heat insulation plate 17A.

[0050] like Figure 5 As shown, the vent 13A includes an air inlet 131A and an air outlet 132A, wherein the air inlet 131A is disposed at the top of the housing 10A and is connected to the control chamber 16A, and the air outlet 132A is disposed at the bottom of the housing 10A and is connected to the outer circulation air duct 12A. When the temperature control fan 14A is in operation, external air is suitable to be sucked in through the air inlet 131A and flows through the control chamber 16A, and then flows into the outer circulation air duct 12A from the connecting port 171A and contacts the heat source 30A, and the hot air heated by the heat source 30A in the outer circulation air duct 12A and the flame retardant produced by the combustion of the heat source 30A are suitable to be discharged through the air outlet 132A. The air inlet 131A is disposed at the top of the housing 10A and is connected to the control chamber 171A, so that when the external air enters the external circulation air duct 12A through the air inlet 132A, it will flow through the control chamber 17A, cool the control chamber 17A, and effectively reduce the temperature of the control chamber 17A. At the same time, the periphery of the heat insulation board 17A is abutted against the inner wall of the housing 10A, which can prevent the heat flow in the external circulation air duct 12A from flowing into the control chamber 17A and causing damage to the control system 40A and the drive motor 50A in the control chamber 17A.

[0051] Embodiment three:

[0052] As attached Figure 6 To Attachment Figure 8 As shown, it is a schematic diagram of a third embodiment of a temperature-adjustable outdoor air fryer provided by the present invention. Compared with the air fryer in the second embodiment, the air fryer in the third embodiment has some identical structural features and working principles, which will not be described here. The difference is that there are differences in the shell structure.

[0053] like Figures 6 to 8As shown, the side of the housing 10B is provided with an auxiliary air port 19B, and the housing 10B is provided with an air guide 80B connecting the auxiliary air port 19B and the outer circulation air duct 12B, and the air guide 80B is suitable for guiding. When the air fryer is working, the air heated by the heat source 30B in the outer circulation air duct 12B and the flame retardant produced by the combustion of the heat source 30B are suitable for being guided to the auxiliary air port 19B through the air guide 80B, and discharged from the auxiliary air port 19B. The auxiliary air port 19B can not only accelerate the discharge speed of the flame retardant produced by the combustion of the heat source 30B in the outer circulation air duct 12B, increase the combustion speed of the heat source 30B, thereby improving the cooking efficiency, but also increase the discharge speed of the air heated by the heat source 30B in the outer circulation air duct 12B, and achieve rapid cooling.
