The buckle fixing mechanism 5 is installed on both sides of the heat shield 3 to buckle and fix the hot air mechanism 4, only need to move the buckle fixing mechanism 5 to the two sides, the hot air mechanism 4 can be released, and the hot air mechanism 4 can be quickly disassembled and assembled. After the hot air mechanism 4 is installed, the food is put into the basket 6, the top cover 7 is covered, the top cover 7 and the heat shield 3 form a heating cavity 8, the conductive driving module 2 is started, and the hot air mechanism 4 generates hot air after being powered on, the hot air blows out from the bottom and continuously circulates in the heating cavity 8, and the food in the basket 6 is heated and cooked.

[0043] During the cooking of the food, the oil and slag generated by the food will fall on the hot air mechanism 4 and the heat shield 3, when the cooking is completed, the hot air mechanism 4 can be taken out by releasing the buckle fixing mechanism 5, and then the hot air mechanism 4 can be cleaned, and the hot air mechanism 4 can be used again after being buckled and fixed.

[0044] In a further optional embodiment, the hot air mechanism 4 comprises an air outlet cover 40, a wind collecting cover 41, a fixing frame 42, a heating tube assembly 43, a first fan blade 44 and a rotating shaft 45. The air outlet cover 40 is a circular cover plate, and a plurality of air vents for hot air flow are arranged on the surface of the cover plate. The wind collecting cover 41 is a cylindrical structure, and is arranged concentrically with the air outlet cover 40. The heating tube assembly 43 and the first fan blade 44 are both arranged in the wind collecting cover 41. When the heating tube assembly 43 and the first fan blade 44 are started, the heat generated by the heating tube assembly 43 is blown out from the wind collecting cover 41 through the first fan blade 44 to form hot air circulating in the heating cavity 8. The fixing frame 42 is arranged on both sides of the bottom of the air outlet cover 40, and the two ends of the fixing frame 42 are screw-connected with the air outlet cover 40. The middle part of the fixing frame 42 is a platform 420, and the clamping fixing mechanism 5 is clamped and fixed on the fixing frame 42 to fix the hot air mechanism 4. The two wire ends 430 of the heating tube assembly 43 are extended from the wind collecting cover 41 and are fixed with the fixing frame 42.

[0045] In a further optional embodiment, as shown in Figure 3 , a layout of the heating tube assembly 43 and the first fan blade 44 is specifically introduced. The heating part 431 of the heating tube assembly 43 is in the shape of a round cake and is close to the air outlet cover 40. The first fan blade 44 is arranged on the side of the heating part 431 away from the air outlet cover 40. When the first fan blade 44 and the heating tube assembly 43 work, the heating tube assembly 43 generates heat when powered, and the generated heat is blown out through the air flow of the first fan blade 44 to form hot air.

[0046] In a further optional embodiment, as shown in Figure 4The specific embodiment shows another layout of the heating pipe assembly 43 and the first fan blade 44, wherein the heating part 431 of the heating pipe assembly 43 is arranged along the inner side wall of the air collecting cover 41, so that the heating part 431 of the heating pipe assembly 43 surrounds an inner cavity, and the first fan blade 44 is installed in the inner cavity of the heating part 431. When the first fan blade 44 and the heating pipe assembly 43 work, the heating pipe assembly 43 generates heat when powered, and the generated heat is blown out by the airflow blown out by the first fan blade 44, and the hot air is blown out from the bottom. In some embodiments, the platform 420 of the fixing frame 42 is provided with two through holes, and the two ends of the heating pipe assembly 43 are respectively provided with clamping blocks 46, the clamping blocks 46 are tapered bodies continuously narrowing towards the ends of the heating pipe assembly 43, and the heating pipe assembly 43 is fixed with the fixing frame 42 through the cooperation of the clamping blocks 46 and the through holes. When it is necessary to disassemble the hot air mechanism 4, the air outlet cover 40 is lifted, and the fixing frame 42 is also lifted. During the lifting process, the clamping blocks 46 gradually approach the wide end, and the heating pipe assembly 43 can be lifted and pulled out after being clamped tightly.

[0047] In some embodiments, the fixing frame 42 is provided with a support block 47, which is in the shape of T. The vertical edge of the support block 47 is fixedly connected with the fixing frame 42, and the horizontal edge of the support block 47 is provided with a recess 470 on each side. The position of the recess 470 corresponds to the clamping of the terminal 430 of the heating pipe assembly 43, and the recess 470 is in cooperation with the terminal 430 of the heating pipe assembly 43 from above. When the hot air mechanism 4 is installed, the terminal 430 of the heating pipe assembly 43 is slightly lifted due to the mutual clamping with the conductive socket 21 during insertion, so that the clamping and limiting of the support block 47 are used to avoid the further movement of the heating pipe assembly 43, thereby playing a limiting role. At the same time, due to the existence of airflow, the heating pipe assembly 43 is disturbed, and the support block 47 supports the heating pipe assembly 43, thereby reducing the influence of disturbance.

[0048] In some optional embodiments, the connection relationship between the buckling fixing mechanism 5 and the fixing frame 42 is specifically introduced. The side of the fixing frame 42 facing the buckling fixing mechanism 5 is provided with a clamping lug 421, and the side of the buckling fixing mechanism 5 facing the fixing frame 42 is provided with a clamping groove 51. The fixing frame 42 and the buckling fixing mechanism 5 are connected through the cooperation of the clamping lug 421 and the clamping groove 51. The buckling fixing mechanism 5 is provided with a linkage module. One side of the linkage module cooperates with the fixing frame 42, and the other side of the linkage module cooperates with the terminal 430 of the heating pipe assembly 43. When the buckling of the clamping lug 421 and the clamping groove 51 is loosened, the linkage module will pry up the terminal 430 of the heating pipe assembly 43, thereby disconnecting the heating pipe assembly 43 and the conductive driving module 2.
