[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings.

[0034] like Figure 1-Figure 8 As shown, an air fryer comprises a body 1 and a pull-out basket 2 which cooperate with each other. A control panel electrically connected to each electrical component is provided on the outer wall of the body 1. The body 1 has an inner cavity 13 and a hot air guide cavity 14 which are interconnected. The hot air guide cavity 14 and the inner cavity 13 of the body are distributed up and down. The pull-out basket 2 can be pushed and pulled and installed in the inner cavity 13 of the body, so that the user can take and put food. The hot air guide cavity 14 is provided with a hot air mechanism 4 electrically connected to the control panel. The hot air mechanism 4 comprises a heating pipe 41 and a hot air fan 42. The hot air fan 42 is located above the heating pipe 41. A low-temperature ventilation layer 18 for internal heat dissipation is provided above the hot air guide cavity 14. A heat dissipation fan 182 is provided in the low-temperature ventilation layer 18. The hot air fan 42 and the heat dissipation fan 182 are coaxially installed and driven by a first motor 43.

[0035] like Figure 2 , Figure 3 , Figure 7 As shown, the pull-out basket 2 has a frying chamber 21, a heat-insulating layer 24 and a detachable food fixing device 3. The heat-insulating layer 24 is located between the frying chamber 21 and the panel of the pull-out basket 2, and is used to insulate the outer layer of the frying chamber 21 to prevent the risk of burns when people touch the pull-out basket 2. The food fixing device 3 is located in the frying chamber 21. Specifically, in order to fit the user's usage habits and the movement patterns of human hands, and to make it more convenient for users to take and put food, the shaft seat 22 is fixedly installed on the inner walls of the front and rear sides of the frying chamber 21 by screws, as shown in FIG. Figure 8 As shown, the shaft seat 22 is "U"-shaped and is provided with a card slot 221. The food fixing device 3 is provided with a rotating shaft 31, and both ends of the rotating shaft 31 are provided with card joints 32, and the card joints 32 are adapted to the card slot 221. The food fixing device 3 is installed inward from the top of the shaft seat 22, and the card joints 32 at both ends are respectively clamped in the corresponding card slots 221. The shaft seat 22 supports and limits it, so that it can be firmly installed in the pull-out basket 2 through the shaft seat 22, and cannot fall off during operation. Specifically, the food fixing device 3 includes but is not limited to utensils such as roasting forks and rotating cages for fixing or holding food. In the utility model, the food fixing device 3 is a roasting fork, which should be understood by those skilled in the art.

[0036] like Figure 2 , Figure 7As shown, in order to enable the food fixing device 3 to rotate so that the food can be turned over during the baking process, a second motor 11 is provided on the machine body 1, and a coupling 12 is provided on the output shaft of the second motor 11, and the coupling 12 is installed through the inner cavity 13 of the machine body. A rotating shaft hole 23 is provided on the pull-out basket 2 at a position corresponding to the coupling 12, and the rotating shaft hole 23 is located above the shaft seat 22. One end of the food fixing device 3 is supported on the shaft seat 22 and connected to the coupling 12 through the rotating shaft hole 23, and the food fixing device 3 is driven to rotate by the second motor 11. The shaft seat 22 plays the role of supporting the food fixing device 4, avoiding the output shaft of the second motor 11 from being subjected to stress, and effectively improving the life of the motor.

[0037] Further, such as Figure 2 , Figure 4 As shown, in order to make the food heated more evenly during the baking process, the top of the hot air guide cavity 14 is set in a "triangle" shape, including a mounting slope 15 and a guide slope 16. The hot air mechanism 4 is installed on the mounting slope 15 and is tilted relative to the frying cavity 21. Figure 7 As shown, when the hot air mechanism 4 is working, the hot air is blown obliquely, which can make the hot air blow over a wider area. At the same time, the hot air in the upper layer flows along the guide slope 16 and flows to the bottom of the frying chamber 21 along the wind flow direction, and bakes the food at the bottom, so that the food is baked more evenly and more comprehensively. At the same time, since the hot air mechanism 4 is set obliquely, the overall height of the body 1 can be effectively reduced, making the volume of the air oven more compact.

[0038] Furthermore, in order to enable the user to observe the progress of food baking in the pull-out basket 2 at any time, a visual window 161 is provided on the guide slope 16. The inclined guide slope 16 enables a wider area in the frying chamber 21 to be observed through the visual window 161, that is, the progress of food baking can be better observed, which is convenient for the user to adjust the baking temperature and time in time.

[0039] Further, such as Figure 3 , Figure 4 , Figure 7 As shown, in order to dissipate heat in time for the machine body 1 and prevent the internal electrical components from being damaged by high temperature, a low-temperature ventilation layer 18 is provided in the machine body 1 above the hot air guide cavity 14. A heat dissipation fan 182 and a heat dissipation port 183 connected to the outside are provided in the low-temperature ventilation layer 18. The air in the low-temperature ventilation layer 18 is connected to the outside through the heat dissipation port 183, and the air circulation in the low-temperature ventilation layer 18 is accelerated by the heat dissipation fan 182 to quickly take away the heat, thereby achieving the effect of heat dissipation and cooling.

[0040] Similarly, in order to achieve a better insulation effect for the heat insulation layer 24, a plurality of basket ventilation holes 25 are provided at the top and bottom thereof to dissipate heat and cool the interior thereof. Correspondingly, the low-temperature ventilation layer 18 is provided with body ventilation holes 181 at the positions corresponding to the basket ventilation holes 25 at the top thereof, so that the heat insulation layer 24 is connected to the low-temperature ventilation layer 18 to dissipate heat and cool the interior thereof, thereby achieving an insulation effect.

[0041] Further, such as Figure 5 , Figure 6 As shown, in order to lock and position the pull-out basket 2 and prevent it from being dislocated from the machine body 1 due to the vibration generated by the rotation of the physical fixing device 3 during operation, a snap mechanism 17 for locking the pull-out basket 2 is provided on the machine body 1. A bullet hole 26 adapted to the snap mechanism 17 is provided on the pull-out basket 2 at a position corresponding to the snap mechanism 17, and the snap mechanism 17 elastically moves in the bullet hole 26 to lock and position the pull-out basket 2. Specifically, the snap mechanism 17 is located on the front side of the machine body 1 facing the personnel, and the bullet hole 26 is located on the top of the heat insulation layer 24.

[0042] Specifically, the snap mechanism 17 includes a cover body 171, an elastic column 172 and a snap cavity 173. The elastic column 172 is provided with a limiting outer edge 175, and the elastic column 172 is covered with a spring, the upper end of the spring abuts against the inner wall of the top of the snap cavity 173, and the lower end abuts against the limiting outer edge 175. The elastic column 172 moves in the snap cavity 173 through the elasticity of the spring. A through hole 174 adapted for the passage of the elastic column 172 is provided at the top of the cover body 171. When the pull-out basket 2 is pulled outward, the elastic column 172 is lifted up, and its lower end is separated from the elastic hole 26, and its upper end is telescopically movable through the through hole 174 until the pull-out basket 2 is pulled out, and there is no obstacle below the elastic column 172 to lift it up, and the elastic column 172 is reset by the spring. Conversely, the same applies when the pull-out basket 2 is pushed into the inner cavity 13 of the machine body for installation.

[0043] Further, such as Figure 3As shown, in order to ensure the practical safety of the user, to avoid the hot air mechanism 4 still working when the pull basket 2 is pulled out, resulting in dry drying of the electrical components inside the air fryer and causing damage, and easily causing scalds, burns and other accidents to the user, a micro switch 19 electrically connected to the heating tube 41 is provided on the body 1, and the micro switch 19 includes a contact 191 and a base 192, the base 192 is located on the pull basket 2, the contact 191 is located on the body 1 at an upper position corresponding to the base 192, and the micro switch 19 is electrically connected to the first motor 43. When the pull basket 2 is pulled out during the baking process, the base 192 is separated from the contact 191, at which time, the first motor 43 controlling the hot air mechanism 4 stops working, so that the hot air mechanism 4 stops heating and baking. When the base 192 is connected to the contact 191 again, the first motor 43 starts again and drives the hot air mechanism 4 and the cooling fan 182 to work.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention and on the basis of the prior art should be within the protection scope determined by the claims.
