In this embodiment, the lower filter screen 61 is provided with a slot and an elastic buckle, and the lower filter screen 61 is movably mounted in the upper partition screen 60 by using the slot and the elastic buckle, so as to facilitate replacement or cleaning of the lower filter screen 61.

Furthermore, a baking tray 30 is arranged at the inner bottom of the inner pot body 3, the cross section of the baking tray 30 is in a continuous wave shape, and the baking tray 30 is in a hollow design, so that the heat generated by the heating tube 40 can reach the bottom of the inner pot body 3 and then rebound to the lower surface of food, and the effect of uniform baking is achieved. The inner pot body 3 and the baking tray 30 are matched in shape, can be round or square, and can also be other shapes, which should not be limited to this.

As shown in fig. 1, fig. 2 and fig. 3, be equipped with in the outer pot body 2 and be used for detecting simultaneously whether the lid 1 is opened and whether the detection inner pot body 3 is built in the outer pot body 2 detection switch device 5 in, this detection switch device 5 is different from current detection switch, utilizes a detection switch just can be with two into one these two functions of the detection of opening a pot and no pot detection, realizes the synthesis in function and the simplification in structure, has good popularization prospect. Detection switch device 5 includes micro-gap switch 50, is used for the activity to open micro-gap switch 50's elastic switch button 51, is used for the rotatory guide part 52 of downward drive elastic switch button 51, is used for detecting lever pivot support 53 of the interior pot body 3, is used for supporting limiting plate 54 of lever pivot support 53 and be used for lever pivot support 53 horizontal hunting's fulcrum 55, micro-gap switch 50 installs the below at elastic switch button 51, elastic switch button 51 resilient mounting is in the one end of lever pivot support 53, the other end of lever pivot support 53 extends to the holding chamber 20 of the outer pot body 2 in and is located the bottom of the interior pot body 3, rotatory guide part 52 install at the articulated position department of the upper cover body 1 and the outer pot body 2 and with elastic switch button 51's top sliding contact. The limiting plate 54 movably supports the left end of the lever rotating shaft support 53, and the fulcrum 55 is arranged on the lever rotating shaft support 53 at a position close to the right end thereof. The rotary guide member 52 is U-shaped and may be made of rubber.

When the inner pot body 3 is placed in the outer pot body 2 and the upper cover body 1 covers the outer pot body 2, see fig. 1, due to the gravity of the inner pot body 3, the lever rotating shaft 53 can swing rightwards from the inclined state by taking the fulcrum 55 as a circle center and is in a horizontal state, at the moment, the elastic switch key 51 moves downwards under the rotation driving of the rotation guide part 52, so that the elastic switch key 51 can press the micro switch 50 downwards and the micro switch 50 is enabled to be connected with a circuit of a control panel and the whole air fryer, and the functions of cover opening detection and no-pot detection are achieved.

Further, lever pivot support 53 includes first supporting part 530, second supporting part 531 and connecting rod 532, first supporting part 530 hangs down on the top of connecting rod 532, second supporting part 531 hangs down on the bottom of connecting rod 532, elastic switch button 51 runs through on locating first supporting part 530, limiting plate 54 is located the below of first supporting part 530, fulcrum 55 is located on second supporting part 531, pot body 3 in the end movable support of second supporting part 531. The elastic switch key 51 comprises a spring and a columnar switch, the bottom of the columnar switch is provided with an anti-falling block to prevent the columnar switch from accidentally falling off from the first supporting part 530, and the first supporting part 530 is provided with a mounting hole for mounting the columnar switch.

When the inner pot body 3 is placed in the accommodating cavity 20 of the outer pot body 2 and the upper cover body 1 is opened from the outer pot body 2, as shown in fig. 2, since the rotary guide part 52 is installed at the hinged position of the upper cover body 1 and the outer pot body 2, the rotary guide part 52 also synchronously rotates anticlockwise in the process that the upper cover body 1 is opened from the outer pot body 2, the elastic switch key 51 slides towards the upper part of the rotary guide part 52, at this time, since the rotary guide part 52 is U-shaped and under the elastic acting force of the elastic switch key 51, the elastic switch key 51 loses the pressing of the rotary guide part 52 and thus moves upwards, so that the elastic switch key 51 is separated from the micro switch 50, at this time, the micro switch 50 is disconnected, the circuit of the control panel and the whole air fryer is disconnected, and the function of cover opening detection.

When the inner pot body 3 is not placed in the outer pot body 2, see fig. 3, the lever rotating shaft support 53 loses the downward pressing gravity of the inner pot body 3, under the combined action of the fulcrum 55, the first supporting portion 530 and the connecting rod 532, the lever rotating shaft support 53 swings leftwards with the fulcrum 55 as a circle center, so that the lever rotating shaft support 53 tilts leftwards and is finally supported on the limiting plate 54, even if the upper cover body 1 covers the outer pot body 2, the elastic switch key 51 tilts along with the lever rotating shaft support 53, the elastic switch key 51 does not have enough displacement to open the microswitch 50 after the rotary guide member 52 presses down the elastic switch key 51, and the microswitch 50 is still in a disconnected state at this moment, so that the function of no-pot detection is achieved.

In addition, this detection switch device 5 can also set up on last lid 1, realizes the function that no pot detected and uncap and detect through opening and shutting of last lid 1, and its specific structure can refer to the above and set up, no longer gives details here.

To sum up, the utility model discloses utilize a detection switching device 5 just can play the boiling pot and detect and do not have the pot to detect these two-way effect, realize the functional two-in-one, have characteristics such as the structure is simple and easy, simple to operate, saved the cost of production simultaneously, have good popularization prospect.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation.
