Under the condition that the top bar 40 is not supported by the pot cover 50, the top bar 40 can be far away from the magnetic switch 30 under the elastic force of the elastic reset piece 90, so that the magnetic switch 30 is switched off. The structure is simple, and a driving device for driving the ejector rod 40 to move does not need to be added, so that the production cost is reduced.

As shown in fig. 4, 5 and 7, in the present embodiment, the guide cylinder 141 is provided on the device body 10, the push rod 40 is provided in the guide cylinder 141 in a floating manner, the first step surface 41 is provided on the push rod 40, the second step surface 142 is provided in the guide cylinder 141, the elastic return member 90 is a spring which is sleeved on the push rod 40, and both ends of the spring are respectively abutted against the first step surface 41 and the second step surface 142. The structure enables the ejector rod 40 to move along the preset direction, avoids the phenomenon that the magnetic block 110 cannot be induced by the magnetic switch 30 due to the deviation of the ejector rod 40, and ensures the reliability of cover closing in-place detection.

As shown in fig. 3 to 5 and 7, in the present embodiment, the fixture body 10 includes an intermediate plate 14 at the top, a guide cylinder 141 is provided on the intermediate plate 14 and extends downward, and the control panel 20 is provided on a side wall of the fixture body 10 and below the guide cylinder 141. Specifically, in the present embodiment, the middle plate 14 is a ring plate, and the above structure enables the push rod 40 to move up and down relative to the middle plate 14, thereby making full use of the effective space in the appliance body 10, avoiding the need to increase the size of the appliance body, and facilitating the miniaturization design.

As shown in fig. 3 to 8, in the present embodiment, the triggering structure 60 is a matching groove recessed upward, and when the lid 50 is rotated to the locking position, the head of the push rod 40 extends into the matching groove, so that the magnetic block 110 is far away from the magnetic switch 30. The structure is simple, the processing is easy, and the reliability is high. Of course, in other embodiments not shown in the drawings, the triggering structure may also be a downward-protruding engaging protrusion, and in the case that the lid 50 is rotated to the locking position, the push rod 40 is pressed down by the engaging protrusion to be close to the magnetic switch 30; or the triggering structure can be a magnetic structure, the top rod 40 is provided with a magnetic block which is repulsive to the magnetic structure, and under the condition that the pot cover 50 rotates to the locking position, the top rod 40 is descended by the magnetic force to be close to the magnetic switch 30.
