The arrangement is such that the third coupling holes 2101 are closer to the upper edge of the side wall 410 of the inner shield 40, which facilitates the stable coupling of the support plate 210 to the inner shield 40.

In some embodiments, as shown in fig. 6, the heating element mounting bracket 20 is a one-piece structure formed by bending a plate body. So set up, on the one hand for heating element mounting bracket 20 can be formed by a plate body processing, convenient processing, save material, and on the other hand, the mechanical properties of integral type structure is good, can improve the joint strength between elastic claw 220, backup pad 210, installation ear 230 and the backstop piece 240.

In some embodiments, as shown in fig. 4, the number of the heat generating component mounting brackets 20 is multiple, the plurality of heat generating component mounting brackets 20 are circumferentially spaced around the central axis of the inner liner 110, and the inner shield 40 surrounds the periphery of the plurality of heat generating component mounting brackets 20. So configured, it is advantageous to stably support the heat generating member 30 and the inner shield 40 by the heat generating member mounting bracket 20.

In a specific application, as an example, optionally, as shown in fig. 4 and 5, the number of the heat generating member mounting brackets 20 is 3 or 4, so that the heat generating member 30 and the inner protective cover 40 can be stably supported in the circumferential direction, and the assembly difficulty is not increased due to an excessive number, thereby facilitating the assembly of the product.

In some embodiments, the pot cover assembly further includes a guide fan blade 120, the guide fan blade 120 is located in the inner shield 40, an upper edge of the first ventilation hole 430 is higher than an upper edge of a blade of the guide fan blade 120, and a lower edge of the first ventilation hole 430 is lower than a lower edge of the blade of the guide fan blade 120. By such arrangement, the inner shield 40 shields the outlet air of the air guide fan blade 120 as little as possible, which is beneficial for the hot air to flow out under the guide of the air guide fan blade 120, has good ventilation effect, is beneficial for the hot air to flow out smoothly and largely, and improves the heating effect.

As shown in fig. 8 to 10, a second aspect of the present invention provides an air fryer, including: a pan body 60; according to the pot cover assembly in any one of the above technical schemes, the pot cover assembly is rotatably connected with the pot body 60, and the cover body 510 covers the pot body 60.

The air fryer provided by the embodiment of the aspect has the beneficial effects of any technical scheme due to the pot cover assembly of any technical scheme, and is not repeated herein.

Optionally, pot body 60 further includes an inner pot 610, a cooking cavity is provided in inner pot 610, and cover assembly 50 covers the cooking cavity. Wherein fig. 8 shows a schematic view of cover assembly 50 covering the cooking cavity, fig. 9 shows inner pot 610 placed inside pot body 60, and fig. 10 shows inner pot 610 removed from pot body 60.

Although the embodiments of the present invention have been described in detail, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that such modifications and variations that may appear to those skilled in the art will still fall within the spirit and scope of the embodiments of the invention as defined by the appended claims.
