When the trigger part is far away from the non-pressing cover body due to high-temperature memory deformation, the elastic part releases elastic potential energy, so that the cover body is bounced off by the elastic part, the cover body can overcome the defects including gravity or gas pressure by means of the elastic part, and the problem that the cover body cannot be normally opened is avoided. Through setting up this elastic component, having removed the restriction of lid opening direction, even if do not rely on the gravity of lid self, also can pop open the lid through the elastic component to the structural position overall arrangement of for the casing provides more choices. Meanwhile, the elastic piece has high reliability, lower failure rate and low maintenance cost compared with a mechanical transmission type opening structure. And then realized optimizing switchgear structure, promoted switchgear reliability and practicality, reduced switchgear manufacturing cost's technological effect.

Specifically, a torsion spring may be selected as the elastic member. One end of the torsion spring is positioned on the housing and the other end is positioned on the cover. The included angle between the two ends in the non-stressed state is larger than the included angle between the cover body and the adjacent shell structure when the cover body covers the shell. Therefore, when the cover body is pressed at the opening of the shell body, the torsion spring is twisted and accumulates potential energy. After the trigger piece deforms, contacts and is in press fit with the trigger piece, the torsion spring releases potential energy and restores to the non-stressed state, so that the cover body can be automatically opened. The torsion spring is a standard part, and the maintenance cost of the production cost of the elastic part can be reduced on the basis of meeting the automatic opening requirement by selecting the torsion spring as the elastic part.

In any of the above aspects, the housing comprises: the box body is arranged on the support piece, and the cover body covers the opening of the box body.

Specifically, the housing includes a box, a bottom wall of the box being disposed on the plate with an opening facing a side away from the plate. The cover body is hinged with the box body to open or close the opening of the box body through rotation. Wherein, the box body can set up the top at the plate, upwards rotates the lid and can open the culinary art chamber, and downwards rotates the lid and then can seal the culinary art chamber through the lid. When the trigger piece releases the pressing fit on the cover body, the elastic piece drives the cover body to overcome the gravity of the cover body to overturn upwards, so that high-temperature steam in the accommodating cavity can enter the box body to heat the food material. The box body has the advantages of low structural complexity, high production cost and high reliability. And, the operation degree of difficulty that the user accessed the food material can be reduced to the opening setting up of box body. Further, the technical effects of optimizing the shell structure and providing convenience conditions for users are achieved.

In any of the above aspects, the housing comprises: the second surrounding edge is arranged on the plate, and the cover body is hinged to the second surrounding edge; on the plate, the through hole is positioned on the outer periphery side of the second surrounding edge.
