Due to the arrangement, the inner shield 40 does not shield the air guide fan blade 120, so that on one hand, hot air is guided by the air guide fan blade 120 to flow out, the ventilation effect is good, the hot air can flow out smoothly and massively, and the heating effect is improved; on the other hand, it is also convenient for tools such as a toothbrush to extend into the space between the top surface of the sidewall 410 of the inner shield 40 and the inner liner 110 for cleaning the air guiding blade 120.

In some embodiments, the spacing between the top surface of the sidewall 410 of the inner shroud 40 and the inner liner 110 is 10mm to 50mm. With such an arrangement, on one hand, the distance between the top surface of the side wall 410 of the inner shield 40 and the liner 110 is large enough, so that the peripheral air outlet area and the heat dissipation area of the inner shield 40 can be increased, the outflow of hot air is facilitated, and the ventilation effect is good; the tool such as toothbrush can conveniently extend into the space between the top surface of the side wall 410 of the inner shield 40 and the inner liner 110 to clean the air guide fan blade 120; on the other hand, it is possible to prevent the space between the top surface of the sidewall 410 of the inner shroud 40 and the liner 110 from being excessively large and wasting space.

In some embodiments, the liner 110 is provided with projections on opposite sides of the fourth connection hole, which engage against the edges of the mounting ears 230. Avoid heating a mounting bracket 20 and rock around the central line of fourth connecting hole through setting up the bulge, conveniently find the position with third connecting hole 231 and fourth connecting hole alignment fast moreover.

In a particular application, the projections are optionally stamped and formed structures on liner 110.

In some embodiments, as shown in fig. 1 and 4, the number of the heat generating component mounting brackets 20 is plural, the plural heat generating component mounting brackets 20 are circumferentially spaced around the central axis of the inner liner 110, and the inner shield 40 encloses the outer periphery of the plural heat generating component mounting brackets 20. It is advantageous to stably support the heat generating member 30 and the inner shield 40 by the heat generating member mounting bracket 20.

As shown in fig. 6 to 8, 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 that this aspect embodiment provided owing to have the pot cover subassembly of any above-mentioned technical scheme, and then has the beneficial effect of any above-mentioned technical scheme, and it gives unnecessary to describe here.

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. 6 shows a schematic view of cover assembly 50 covering the cooking cavity, fig. 7 shows inner pot 610 placed inside pot body 60, and fig. 8 shows inner pot 610 removed from pot body 60.

Although the embodiments of the present invention have been described in detail above, those skilled in the art may 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 would still fall within the spirit and scope of the embodiments of the present invention, as defined by the appended claims, as seen by those skilled in the art.
