[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0028] Combine the following Figure 1-Figure 9 An air fryer according to an embodiment of the utility model is described.

[0029] The air fryer according to the embodiment of the utility model comprises a pot body 4, a motor 5, an inner pot 1, a stirring paddle 3 and a head assembly 2, wherein the motor 5 is mounted on the pot body 4. The inner pot 1 is detachably mounted in the pot body 4, the inner pot 1 defines a cooking cavity, a transmission shaft 8 is rotatably mounted on the bottom wall of the inner pot 1, and the transmission shaft 8 is connected to the rotating shaft of the motor 5. The stirring paddle 3 is arranged in the cooking cavity, and the lower end of the stirring paddle 3 is connected to the transmission shaft 8. The head assembly 2 comprises a head 21, a hot air assembly 22 and an air guide hood 23, the head 21 is connected to the pot body 4 and covers the inner pot 1, the hot air assembly 22 is mounted on the head 21, the air guide hood 23 is pivotally connected to the head 21, the air guide hood 23 separates the hot air assembly 22 from the cooking cavity, and the air guide hood 23 is connected to the upper end of the stirring paddle 3, so that the stirring paddle 3 drives the air guide hood 23 to rotate when the stirring paddle 3 rotates.

[0030] According to the air fryer of the embodiment of the utility model, the motor 5 installed on the pot body 4 is connected to the stirring paddle 3 through the transmission shaft 8, so as to drive the stirring paddle 3 to rotate and tumble the food in the cooking cavity, so as to ensure that the food is heated evenly. On this basis, when the head 21 of the head assembly 2 is covered on the inner pot 1, the air guide cover 23 is connected to the upper end of the stirring paddle 3, so that when the stirring paddle 3 rotates, the air guide cover 23 can be driven to rotate relative to the head 21, and then the hot air generated by the hot air assembly 22 can be uniformly introduced into the cooking cavity by the air guide cover 23 when passing through the air guide cover 23, so that the temperature in the cooking cavity is uniform and the food cooking efficiency is high.

[0031] It should be noted that the air guide cover 23 of some air fryers in the related art is also pivotally connected to the machine head 21, but the air guide cover 23 is rotated under the drive of a driving device installed in the machine head 21. In the embodiment of the utility model, the stirring paddle 3 is coaxially connected to the air guide cover 23, and the stirring paddle 3 and the air guide cover 23 can be synchronously rotated by only the motor 5 on the pot body 4, and there is no need to install a driving device in the machine head 21, thereby effectively reducing the production cost of the air fryer.

[0032] In some embodiments, Figure 2 , Figure 8 and Fig. 9 As shown, the air fryer also includes a first connecting member 6 and a second connecting member 7, the first connecting member 6 is connected to the upper end of the stirring paddle 3, the second connecting member 7 is connected to the air guide cover 23, one of the first connecting member 6 and the second connecting member 7 includes a plurality of first teeth 62 arranged at intervals along the circumference of the air guide cover 23, and a portion of the other of the first connecting member 6 and the second connecting member 7 is fitted between two adjacent first teeth 62.

[0033] By arranging a part of one of the first connecting member 6 and the second connecting member 7 to fit between two adjacent first teeth 62 of the other, the first connecting member 6 and the second connecting member 7 interfere with each other in the circumferential direction, and then when the stirring paddle 3 drives the first connecting member 6 to rotate, the first connecting member 6 can drive the second connecting member 7 and the air guide cover 23 connected thereto to rotate synchronously. Moreover, the first connecting member 6 and the second connecting member 7 are movably connected, and when the machine head 21 is opened, the air guide cover 23 will not bring the stirring paddle 3 out of the inner pot 1, and the machine head 21 can be opened smoothly.

[0034] For example, Figure 6 and Fig. 9 As shown, the first connecting member 6 includes a plurality of first teeth 62, and a portion of the second connecting member 7 fits between two adjacent first teeth 62. When the stirring paddle 3 drives the first teeth 62 to make a circular motion, the first teeth 62 abut against a portion of the second connecting member 7 located between two adjacent first teeth 62 and push the portion to make a circular motion, thereby driving the wind guide cover 23 to rotate synchronously.

[0035] In some embodiments, Figure 6-Figure 9As shown, the first connecting member 6 also includes a first substrate 61, which is connected to the stirring paddle 3 through a first threaded member, and a first tooth 62 is arranged on the side of the first substrate 61 away from the stirring paddle 3. The second connecting member 7 includes a second substrate 71 and a second tooth 72, which is connected to the air guide cover 23 through a second threaded member, and the second tooth 72 is arranged on the side of the second substrate 71 facing the stirring paddle 3. The number of the second teeth 72 is equal to that of the first teeth 62, and the plurality of second teeth 72 and the plurality of first teeth 62 are alternately arranged along the circumference of the air guide cover 23, and the plurality of second teeth 72 can abut against different first teeth 62 at the same time.

[0036] This arrangement ensures that when the stirring paddle 3 drives the air guide cover 23 to rotate, each first tooth 62 abuts against a different second tooth 72 and gives the corresponding second tooth 72 the same thrust. At this time, the interaction force between each first tooth 62 and the corresponding second tooth 72 is smaller, the first tooth 62 and the second tooth 72 are not easily bent, deformed or damaged due to excessive force, and the service life of the first connecting member 6 and the second connecting member 7 is increased.

[0037] For example, the first threaded member has one bolt, which passes through the mounting hole on the stirring paddle 3 and is threadedly matched with the threaded hole on the first substrate 61, and the second threaded member has one bolt, which passes through the mounting hole on the air guide cover 23 and is threadedly matched with the threaded hole on the second substrate 71. The axes of the mounting holes on the stirring paddle 3 and the air guide cover 23 coincide with the center line of the stirring paddle 3.

[0038] In some embodiments, Fig. 9 As shown, the first connecting member 6 is a plastic member, and / or the first connecting member 6 also includes a connecting seat 63, which is arranged on the side of the first substrate 61 away from the first shifting tooth 62, and a limiting groove 31 is provided on the stirring paddle 3, and the limiting groove 31 is a special-shaped groove, and the connecting seat 63 is fitted in the limiting groove 31.

[0039] By setting the first connecting member 6 as a plastic member, the collision between the first connecting member 6 and the second connecting member 7 when the first connecting member 6 drives the second connecting member 7 to rotate is not a rigid collision, and the noise generated by the collision is lower. By respectively setting a matching connecting seat 63 and a limiting groove 31 on the first connecting member 6 and the stirring paddle 3, the relative fixation of the first connecting member 6 and the stirring paddle 3 in the circumferential direction of the stirring paddle 3 can be effectively ensured, and at this time, only one first threaded member is required to achieve the relative fixation of the first connecting member 6 and the stirring paddle 3 in the axial direction of the stirring paddle 3, and the assembly efficiency between the first connecting member 6 and the stirring paddle 3 is high.

[0040] For example, Fig. 9 As shown, the limiting groove 31 is arranged on the upper surface of the stirring paddle 3, the depth direction of the limiting groove 31 is consistent with the axial direction of the stirring paddle 3, and the cross-sectional outer contour of the limiting groove 31 is substantially rectangular.

[0041] In some embodiments, Figure 8 As shown, one of the air guide cover 23 and the second base plate 71 is provided with a first protrusion 73 , and the other of the air guide cover 23 and the second base plate 71 is provided with a first limiting hole 231 , and the first protrusion 73 fits in the first limiting hole 231 .

[0042] The matching first protrusion 73 and the first limiting hole 231 can effectively ensure the relative fixation of the air guide cover 23 and the second connecting member 7 in the circumferential direction of the air guide cover 23. At the same time, only one second threaded member is required to realize the relative fixation of the air guide cover 23 and the second connecting member 7 in the axial direction of the air guide cover 23. The assembly efficiency between the second connecting member 7 and the air guide cover 23 is high.

[0043] For example, Figure 8 As shown, there are four first limiting holes 231 which are evenly spaced on the air guide cover 23 along the circumference of the air guide cover 23 , and four first protrusions 73 are correspondingly provided, and the first protrusions 73 fit in the corresponding first limiting holes 231 .

[0044] In some embodiments, Figure 2 As shown, the first shifting tooth 62 includes a first limiting surface 621 and a first guiding surface 622 which are opposite to each other along the circumference of the wind guide cover 23, the first limiting surface 621 is parallel or coplanar with the center line of the wind guide cover 23, and the distance between the first guiding surface 622 and the first limiting surface 621 gradually decreases in the direction away from the first substrate 61. The second shifting tooth 72 includes a second limiting surface and a second guiding surface which are opposite to each other along the circumference of the wind guide cover 23, the second limiting surface is parallel or coplanar with the center line of the wind guide cover 23, the distance between the second guiding surface and the second limiting surface gradually decreases in the direction away from the second substrate 71, and the second limiting surface can be in close contact with the first limiting surface 621.

[0045] The first tooth 62 and the second tooth 72 are respectively provided with a first limiting surface 621 and a second limiting surface which are parallel or coplanar with the center line of the air guide cover 23. The first tooth 62 contacts the second limiting surface of the second tooth 72 through the first limiting surface 621 and pushes the second tooth 72 to make a circular motion. In this process, no force will be generated along the axial direction of the air guide cover 23 between the two, and the transmission between the two is reliable. Moreover, the distance between the first guide surface 622 and the first limiting surface 621 is gradually reduced in the direction away from the first substrate 61, and the distance between the second guide surface and the second limiting surface is gradually reduced in the direction away from the second substrate 71. When the machine head 21 is closed, the second tooth 72 is more easily matched between two adjacent first teeth 62, and the first guide surface 622 of one of the first teeth 62 can be slidably matched with the second guide surface of the second tooth 72, so that the second limiting surface of the second tooth 72 automatically abuts against the first limiting surface 621 of the other first tooth 62, and the connection between the stirring paddle 3 and the air guide cover 23 is convenient and accurate.

[0046] It should be noted that when the first connecting member 6 pushes the second connecting member 7 to rotate, the first limiting surface 621 is in close contact with the second limiting surface, thereby making the local pressure on each of the first shifting tooth 62 and the second shifting tooth 72 smaller, making the first shifting tooth 62 and the second shifting tooth 72 less likely to deform, and extending the service life of the first connecting member 6 and the second connecting member 7.

[0047] In some embodiments, the number of the first teeth 62 and the second teeth 72 is n, where n is an integer and 2≤n≤5. Setting the number of the first teeth 62 and the second teeth 72 to five can further reduce the interaction force between each first tooth 62 and the corresponding second tooth 72, and reduce the risk of deformation of the first connecting member 6 and the second connecting member 7. Setting the number of the first teeth 62 and the second teeth 72 to two can make the cooperation between the second teeth 72 and the first teeth 62 more convenient and faster, and the probability of interference by the second teeth 72 when the head 21 is closed is lower, and the closing of the head 21 is smoother.

[0048] For example, Figure 2 As shown, the number of the first teeth 62 and the second teeth 72 is five. At this time, the torque of the air guide cover 23 driving the stirring paddle 3 to rotate is divided into five parts, thereby making the interaction force between each first tooth 62 and the second tooth 72 smaller.

[0049] In some embodiments, Figure 5-Figure 7 and Fig. 9 As shown, the air fryer also includes a knife seat 9, which is detachably connected to the lower end of the stirring paddle 3 through a third threaded member, and the knife seat 9 is provided with a second limiting hole, which is a special-shaped hole. The transmission shaft 8 includes a first shaft segment located in the cooking cavity, and the cross-sectional outer contour of the first shaft segment matches the cross-sectional outer contour of the second limiting hole, and the first shaft segment is gap-matched with the special-shaped hole.

[0050] The blade holder 9 is connected to the stirring paddle 3, and the first shaft section of the transmission shaft 8 located in the cooking cavity is gap-matched with the second limiting hole on the blade holder 9, so that the stirring paddle 3 is conveniently and quickly connected to the transmission shaft 8. Moreover, the stirring paddle 3 can be pulled out of the inner pot 1 by simply pulling the stirring paddle 3 upward, which greatly facilitates the subsequent processing of the cooked ingredients in the cooking cavity, and also facilitates the cleaning of the inner pot 1 and the stirring paddle 3, and the user experience is high.

[0051] For example, Figure 5 As shown, the second limiting hole is a D-shaped hole, the outer contour of the cross section of the first shaft section is D-shaped, and the stirring paddle 3 moves vertically downward, so that the second limiting hole can be sleeved on the first shaft section to realize the transmission connection between the transmission shaft 8 and the stirring paddle 3. The knife seat 9 is connected to the stirring paddle 3 by two bolts, so that the knife seat 9 and the stirring paddle 3 can be easily disassembled and assembled.

[0052] In some embodiments, Figure 6 , Figure 7 and Fig. 9 As shown, the air fryer further includes a stirring seat 10, a locking member 110 and a first clutch 120. A first mounting hole is provided on the bottom wall of the inner pot 1, at least a portion of the stirring seat 10 passes through the first mounting hole and protrudes outside the inner pot 1, a second mounting hole is provided on the stirring seat 10, the second mounting hole passes through the stirring seat 10 along the axial direction of the transmission shaft 8, and the transmission shaft 8 is rotatably fitted in the second mounting hole. The locking member 110 is connected to the portion of the stirring seat 10 located outside the inner pot 1, so that the bottom wall of the inner pot 1 is clamped between the locking member 110 and the stirring seat 10. The transmission shaft 8 includes a second shaft section protruding outside the inner pot 1, and the first clutch 120 is coaxially connected to the second shaft section. The second clutch 130 is coaxially connected to the rotating shaft of the motor 5, and the second clutch 130 is provided with a third limiting hole, the third limiting hole is a special-shaped hole, the cross-sectional outer contour of the third limiting hole matches the cross-sectional outer contour of the first clutch 120, and at least a portion of the first clutch 120 is fitted in the third limiting hole.

[0053] By setting the transmission shaft 8 to rotate and fit in the second installation hole of the stirring seat 10, after the second shaft section of the transmission shaft 8 is coaxially connected with the first clutch 120, the entire transmission shaft 8 can pass through the first installation hole downward from the cooking cavity, and then the locking member 110 is connected to the stirring seat 10 to complete the installation of the transmission shaft 8 and the second clutch 130 on the inner pot 1, which is convenient and quick to install. Moreover, the motor 5 drives the transmission shaft 8 and the stirring paddle 3 to rotate through the plug-in cooperation of the first clutch 120 and the second clutch 130, and the inner pot 1 can be lifted out of the pot body 4 by simply pulling the inner pot 1 upward, which is convenient for subsequent processing of the food in the cooking cavity and also convenient for cleaning the inner pot 1.

[0054] For example, Fig. 9 As shown, the third limiting hole on the second clutch 130 is a plum blossom hole, and the locking member 110 is a nut, which is threadedly connected to the stirring seat 10 so that the bottom wall of the inner pot 1 is clamped between the nut and the stirring seat 10. The diameter of the first shaft section in the transmission shaft 8 is larger than the diameter of the second mounting hole, thereby preventing the transmission shaft 8 from slipping out of the second mounting hole downward; at the same time, the first clutch 120 is interference-fitted on the second shaft section, and under the limitation of the first clutch 120, the transmission shaft 8 is also prevented from slipping out of the first mounting hole upward. Figure 6 As shown, a first sealing ring is installed between the transmission shaft 8 and the wall of the second mounting hole, and a second sealing ring is installed on the first shaft section for abutting against the wall of the second limiting hole, thereby ensuring the sealing performance of the bottom wall of the inner pot 1 and effectively preventing the food in the cooking cavity from leaking out.

[0055] In some embodiments, Fig. 9As shown, the pot body 4 includes an outer shell 41 and an inner liner 42 connected to each other, a first chamber is defined between the inner liner 42 and the outer shell 41, and a second chamber is defined by the inner liner 42. The motor 5 is installed in the first chamber, and the inner pot 1 is detachably installed in the second chamber. The inner liner 42 is provided with a third mounting hole connecting the first chamber and the second chamber, and at least part of the second clutch 130 passes through the third mounting hole and is located in the second chamber.

[0056] That is, the motor 5 and part of the second clutch 130 are hidden in the first chamber, which effectively prevents the two from being exposed and affecting the appearance of the air fryer.

[0057] For example, the lining 42 is made of a heat-insulating material, thereby effectively preventing the temperature of the inner pot 1 from being transferred to the pot body 4 and causing the pot body 4 to be overheated and cause harm to the user.
