Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan, especially a kind of electric pressure cooking saucepan of automatic Regulation.
Background technology
But the electric pressure cooking saucepan of automatic Regulation on the market is of a great variety at present, and along with the development of society, but people have made improvement repeatedly to the electric pressure cooking saucepan of pressure regulation.For example: disclose a kind of electric pressure cooking saucepan of automatic Regulation Chinese patent ZL:02248147.8 number, it comprises pot cover, shell, interior pot, outer pot, heat-generating disc, elastomer and base, interior pot places on the outer pot, the upper edge of pot in sealing ring places, and between outer pot and the interior pot space is arranged, elastomer places on the outer pot bottom surface in the space, contact with the heat-generating disc of interior pot bottom, make between outer pot and the interior pot and be elastic construction, one end of one catch bar is fixed on the heat-generating disc, the other end passes the through hole of outer pot bottom, stretch on the movable contact spring of pressure control switch, elastomer is the plate-like elastomer of hollow structure, and this plate-like elastomeric perimeter is provided with flange, and it is solid between heat-generating disc and outer pot elastomer that connector passes the elastomeric flange of plate-like.This product pushes heat-generating disc downwards by the continuous increased pressure of interior pot, makes elastomer that downward deformation take place to push, and the end that heat-generating pipe is relative produces to bottom offset, until disconnecting the pressure control switch, interior pot is no longer heated boost.
Though this product has been realized the purpose of automatic Regulation, but in the production of product and actual use, 1), the electric pressure cooking saucepan of said structure still deposits following defective:, because elastomer is the plate-like elastomer of hollow structure, be subjected to big influence of the elastomeric bulk metal intensity of plate-like, its deformation coefficient is little, and the precision of pressure control is not high, so the elastomeric application of this plate-like is restricted; 2) be to be difficult to realize, between two plate-like elastomers when stacked, adopt above-mentioned connector that two elastomeric peripheries of plate-like are fully overlaped,, be subjected to its incomplete eclipse effect, easy pressurized causes dislocation between two plate-like elastomers, and discontinuity causes pressure control inaccurate; 3), that the plate-like elastomer of this structure has a volume and weight is big, cost height, and processing and mounting hardness are also bigger, have increased production cost.The utility model content
The purpose of this utility model be to solve above-mentioned shortcoming and provide a kind of simple in structure, adult is low, volume is little, in light weight, handling ease, assembles the electric pressure cooking saucepan of the automatic Regulation of convenient and pressure precise control.
The purpose of this utility model is achieved in that a kind of electric pressure cooking saucepan of automatic Regulation, comprise pot cover, shell, outer pot, base, heat-generating disc, place interior pot, elastomer and pressure switch on the heat-generating disc, being provided with elastomer between described heat-generating disc and the outer pot bottom is connected, also be provided with the elastomer distortion on the heat-generating disc and can touch the catch bar of pressure switch, described elastomer is provided with the bearing surface that is connected with heat-generating disc, and be supported on flexible feet on the outer pot bottom, be provided with at least one pair of described elastomer between described heat-generating disc and the outer pot bottom.Described flexible feet is located at the both sides of bearing surface, and flexible feet is extension outward.Described elastomer is
Shape, the bearing surface on its top and heating valve snail admittedly together, the bottom of flexible feet is provided with the flange with outer pot basal sliding friction.Described heat-generating disc is provided with draw-in groove, on the elastomer leg that should draw-in groove is provided with the fixture block of the described draw-in groove of fastening.Be provided with three elastomers between described heat-generating disc and the outer pot bottom, elastomer is circle-shaped even setting along described heat-generating disc.The bottom of described heat-generating disc also is provided with pillar, and the outer pot bottom of corresponding pillar has through hole, and pillar passes described through hole and is fixed on the described through hole.The bottom of described heat-generating disc is provided with three pillars, and pillar is circle-shaped even setting along described heat-generating disc.
The beneficial effects of the utility model are: 1) because described elastomer is provided with the bearing surface that is connected with heat-generating disc, and be supported on flexible feet on the outer pot bottom, it is out of shape good linearity, the displacement that elastomer is produced is even, reset easily, pressure control is accurately with safe and reliable, and elastomer structure is simple, the low and handling ease of cost; 2) elastomer is evenly distributed between the heat-generating disc and outer pot of symmetry, integral body is circle distribution, so not only increase the stability of heat-generating disc, help elastomeric balance, pot is stabilized on the outer pot bottom surface in making, and, because elastomer is that point-like contacts with the outer pot bottom surface, heat-generating disc significantly reduces the friction of elastomer and outer pot bottom surface when being under pressure like this; 3) three important actors on the heat-generating disc owing to corresponding through hole with outer pot aligns, and are fastened on the outer pot bottom surface, can avoid moving freely of heat-generating disc, and the defective of pot sealing difference in occurring; 4) positioning bar at elastomer edge can play the direction positioning action in assembling, quick and easy for installation.
