Abstract
The invention relates to a safe pressure cooker for daily use. The pot cover comprises a pot cover component (1) and a pot body (2), wherein a sealing ring (12) is installed on a contact surface between the pot cover component (1) and the pot body (2), pot teeth (3) and an elastic device (4) which can float up and down are arranged between cover teeth of the pot cover component (1) and a pot edge (21) of the pot body (2), and the cover teeth of the pot cover component (1) are buckled with the pot teeth (3). A guiding device for preventing the pot teeth (3) from rotating radially is arranged between the pot body (2) and the pot teeth (3), and a limiting device (5) for limiting the vertical floating range of the pot teeth (3) is arranged on the pot body (2). When the pressure in the cooker is increased, the cooker cover component drives the cooker teeth to move upwards, and an air leakage gap is formed between the sealing ring and the cooker edge or the cooker cover component, so that the purposes of air leakage, pressure reduction and cooker explosion prevention are achieved. The invention has simple structure, easy realization, convenient use and stable performance.

Summary of the invention
The objective of the invention is to consider the problems referred to above and provide a kind of simple in structure, be easy to realize, easy to use, the pressure cooker of stable performance.
Structural representation of the present invention as shown in Figure 1, include pot cover component (1), pot body (2), contact-making surface between pot cover component (1) and the pot body (2) is equipped with sealing ring (12), wherein be provided with the pot tooth (3) and the elastic device (4) that can fluctuate between the pot edge (21) of the lid tooth of pot cover component (1) and pot body (2), the lid tooth of pot cover component (1) is interlocked with pot tooth (3).
Above-mentioned elastic device (4) is placed up and down successively with pot tooth (3).
The lid tooth of above-mentioned pot cover component (1) fastens or outer the fastening with pot tooth (3) is interior.
Above-mentioned elastic device (4) is metallic elastic component or is nonmetal flexible member.
Above-mentioned metallic elastic component is sheet spring or helical spring, and the material of nonmetal flexible member is rubber or plastics.
Above-mentioned pot tooth (3) is separate several pots tooth, or is provided with the pot tooth coil of several pots tooth.
Be provided with the guider that stops pot tooth (3) radially to rotate between above-mentioned pot body (2) and the pot tooth (3).
Above-mentioned guider is a gathering sill and the cooperating of lead or guiding rib, or the cooperating of fairlead and the axis of guide, or can stop a pot tooth (3) radially to rotate, but still can make the mechanical attachment that a pot tooth (3) fluctuates or physics is bonding or chemical adhesive.
Above-mentioned pot body (2) is provided with and limits the fluctuate stopping means (5) of scope of pot tooth (3).
Above-mentioned stopping means (5) is banking pin or limited post or limiting gasket, or for pot tooth (3) is riveted or is bonded on a pot body (2) or the elastic device (4).
Pot tooth that the present invention owing to be provided with between the pot edge of the lid tooth that adopts pot cover component and pot body can fluctuate and the structure of elastic device, in the pot during normal pressure, sealing is realized by sealing ring in gap between the pot edge of pot cover component and pot body, when pot inner pressure increases, pot cover component drives the pot tooth to top offset, gap between the pot edge of pot cover component and pot body becomes big, when pot inner pressure surpasses safe limit pressure, during gap that the gap between the pot edge of pot cover component and pot body can seal greater than sealing ring, produce the gap of losing heart between sealing ring and pot edge or pot cover component, pot inner high voltage gas releases, and reaches disappointing step-down, prevents the security purpose of quick-fried pot.The present invention is simple in structure, is easy to realize that easy to use, stable performance is that a kind of design is ingenious, function admirable, convenient and practical pressure cooker.
