Abstract
The utility model discloses an automatic reset pressure relief device for a pressure cooker, which comprises an elastic pressure relief plate and a base plate which are connected with each other, wherein the base plate is arranged around the inner surface of the bottom of the outer cooker of the pressure cooker to be in a steering wheel shape, so the contact area of the base plate and the elasticpressure relief plate is enlarged, the service life of the elastic pressure relief plate is greatly prolonged under the support of the base plate, the stability of the pressure of the pressure cookeris ensured, and the product is safe to use, in addition, the service life of the inner structural parts of the product is prolonged.
Description
Technical field
The utility model relates to a kind of pressure relief device that automatically resets of pressure cooker.
Background technology
In order further to improve the security and the stability of pressure cooker internal pressure, on pressure cooker, be provided with pressure relief device, this pressure relief device mainly is made up of elasticity pressure relief plate and the backing plate that is positioned on the pressure cooker outer pot.After pressure control device lost efficacy, the pressure of interior pot constantly rose, when pressure reaches the pressure release value, and interior pot pressurized, the temperature distortion of elasticity pressure relief plate forms bigger space between pot and the outer pot in making, and pressure releases from the space; After the pressure release of interior pot, recover the origin-location after the heating board decompression, stop roof pressure to the elasticity pressure relief plate, elasticity pressure relief plate heat radiation back is recovered original state automatically.The pressure relief device of said structure is realized the purpose of safety relief, yet, backing plate only is positioned on the periphery of outer pot, backing plate only supports the edge of elasticity pressure relief plate, make elasticity pressure relief plate major part be in vacant state, cause the elasticity pressure relief plate aging easily in the distortion repeatedly and the back that resets, relieving characteristics descends, thereby influences the service property (quality) of pressure cooker.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, prolong elasticity pressure relief plate service life and improve the pressure relief device that automatically resets of the pressure cooker of reset capability greatly.
Goal of the invention of the present utility model is achieved in that a kind of pressure relief device that automatically resets of pressure cooker, comprise elasticity pressure relief plate and the backing plate of being located at pressure cooker heating board bottom, described elasticity pressure relief plate and backing plate interconnect, and it is characterized in that: described backing plate is surrounded on the pressure cooker outer pot bottom interior surface.
Described backing plate is the direction plate-like and is connected with pressure cooker outer pot one, and the elasticity pressure relief plate is connected with pressure cooker outer pot bottom interior surface by backing plate.
Described elasticity pressure relief plate is fixedlyed connected with backing plate with the pressure cooker heating board by clamping screw.
The utility model improves the pressure relief device that automatically resets of the pressure cooker of prior art, change the structure of backing plate, backing plate is surrounded on the pressure cooker outer pot bottom interior surface, specifically be to be the direction plate-like, increase the contact area of backing plate and elasticity pressure relief plate, the elasticity pressure relief plate increases the service life under the support of backing plate greatly, has guaranteed the stability of the pressure in the pressure cooker, makes the safe in utilization of product and has prolonged service life of product inner structure parts.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment;
Accompanying drawing 2 is STRUCTURE DECOMPOSITION figure of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
With reference to the accompanying drawings 1 and accompanying drawing 2 shown in, the pressure relief device that automatically resets of the utility model pressure cooker comprises elasticity pressure relief plate 1 and backing plate 2.Elasticity pressure relief plate 1 is a metal material, employing manganese metal the best, secondly also can adopt metal materials such as mild steel, iron plate, elasticity pressure relief plate 1 is positioned at pressure cooker heating board 3 bottoms, this elasticity pressure relief plate 1 shape size is suitable with pressure cooker outer pot 4 bottoms, elasticity pressure relief plate 1 middle part has the installing hole adaptive with clamping screw, is fixed on the pressure cooker outer pot 4 by clamping screw elasticity pressure relief plate 1.Backing plate 2 is surrounded on pressure cooker outer pot 4 bottom interior surfaces, and this backing plate 2 is connected with pressure cooker outer pot 4 one.Backing plate 2 is the direction plate-like, makes edge, middle part and the center of elasticity pressure relief plate 1 all obtain backing plate 2 and supports, and on the basis that guarantees relieving characteristics, has dwindled the unsettled area of elasticity pressure relief plate 1 greatly, effectively prolongs the service life of elasticity pressure relief plate.When pressure cooker is in running order, after pressure control device lost efficacy, the pressure of interior pot constantly rises, when pressure reaches the pressure release value, 3 pairs of elasticity pressure relief plates of pressure pushing pressure pot heating board 1 carry out roof pressure, pressure cooker heating board 3 is sent to heat on the elasticity pressure relief plate 1, elasticity pressure relief plate 1 the be under pressure pressure of pot heating board 3 and heat energy and be out of shape, be closely attached on backing plate 2 and pressure cooker heating board 3 bottom interior surfaces, increased the gap of inner bag and pressure cooker heating board 3, pressure releases from the gap between inner bag and the pressure cooker heating board 3; After the pressure release of interior pot, recover the origin-location after pressure cooker heating board 3 decompressions, stop roof pressure to elasticity pressure relief plate 1, elasticity pressure relief plate 1 heat radiation back is recovered original state automatically.
Claims (3)
