In the process that the lifting handle 54 is clamped into the mounting groove 12, the lifting handle 54 generates an elastic force on the elastic sheet 7, so that the elastic sheet 7 clamps the oil separation net 5, and the oil separation net 5 is further fixed on the fixing frame 6; the handle 54 is lifted, and the oil separation net 5 can be detached from the elastic sheet 7. When the oil separation net 5 is installed and disassembled, hands cannot touch the elastic sheet 7, and the safety is high; the service life of the elastic sheet 7 is long. Simultaneously, when going into handle 54 card into mounting groove 12, mounting groove 12 has carried out preliminary fixed to separating oil net 5, continues to adopt shell fragment 7 fixed when separating oil net 5, separates oil net 5 and can not remove, has improved the assembly convenience. In addition, the handle 54 is provided to facilitate access and cleaning of the oil barrier 54. Preferably, the mounting groove 12 is provided on the left or right side of the elastic sheet 7, which is more advantageous for the detachment of the oil screen 5 and has good aesthetic property.

Further, a fastening member is mounted on the air duct plate 2 or the heating element 3 or the fixing frame 6, and the fastening member is used for simultaneously fixing the heating element 3 and the fixing frame 6 on the air duct plate 2. In this embodiment, the fastening member includes a first connecting portion through which the fixing frame 6 is fixed to the heating element 3 and a second connecting portion through which the heating element 3 is fixed to the air duct plate 2, so that the fastening member simultaneously fixes the heating element 3 and the fixing frame 6 to the air duct plate 2. In this embodiment, through a fastener with heating element 3 and mount 6 fixed mounting on air duct board 2 simultaneously for form the cavity of relative seal between air duct board 2, heating element 3 and the mount 6, improved hot-air's circulation efficiency, saved installation space, this kind of mounting means is simple convenient moreover, need not unnecessary connecting piece, has fine practicality. The fastener is exemplified by a stud 13, one end of the stud 13 is provided with internal threads, the other end is provided with external threads, and the fixing frame 6 and the heating element 3 are arranged on the air duct board 2 through the stud 13. Specifically, a first mounting hole is formed in the fixing frame 6, a clamping block is arranged on the side wall of the heating element 3, and a second mounting hole is formed in the clamping block at a position corresponding to the first mounting hole; and a third mounting hole is arranged on the air duct plate 2 at a position corresponding to the second mounting hole, and the first mounting hole, the second mounting hole and the third mounting hole are collinear. The stud 13 passes through the first mounting hole, the second mounting hole and the third mounting hole in sequence, and then the fixing frame 6 and the heating element 3 are mounted on the air duct plate 2 under the matching of a screw or a nut. It should be noted that, in this embodiment, the order of mounting the air duct plate 2, the heating element 3, and the fixing frame 6 is not limited to this, and the stud 13 of this embodiment may be replaced by another fastener, as long as one fastener is used to mount the heating element 3 and the fixing frame 6 to the air duct plate 2 at the same time.

Further, referring to fig. 6, the oil separating net 5 includes a first filter screen 51, and the first filter screen 51 is in a planar grid shape; and a second filter screen 52 attached to the first filter screen 51, wherein the second filter screen 52 is in a wave grid shape. In this embodiment, through double-deck filter screen, can be better block the grease entering heating chamber of 1 top in culinary art chamber, make the heating intracavity become safety, clean. The first filter screen 51 is plane, so that the aesthetic property of the air fryer when the air fryer is opened and the safety in the disassembling process are ensured; the second filter screen 52 is wavy and has a plurality of inclined surfaces, which can prevent the grease from being blown around, and further prevent the grease from entering the interlayer between the air duct plate 2 and the upper core or other parts to cause the situation of difficult cleaning. In addition, when the first filter screen 51 and the second filter screen 52 are attached to each other, they are supported by each other, and a certain gap is formed between them, so that the oil separation screen 5 is not deformed when the thermal circulation fan 4 rotates, and the resistance when the thermal circulation air flows into the cooking cavity 1 is reduced. When the oil separation net is installed, the first filter net 51 and the second filter net 52 are first installed on the fixing ring 53, and then the oil separation net 5 is installed on the fixing frame 6 through the handle 54 on the fixing ring 53.

Further, referring to fig. 7 and 8, an annular oil storage groove 8 is formed in the oil separation net 5 and used for collecting grease on the oil separation net 5.
