Abstract
The utility model belongs to a domestic pressure cooker which has the advantages of explosion prevention, safety protection and simple structure. The utility model mainly solves the problems of few safety devices and the existence of explosion incipient faults. The utility model is mainly characterized in that the utility model comprises a cooker body, a cooker lid and a pressure limiting valve, wherein, an elastic disc is arranged on the inner surface of the cooker lid, and a pressure releasing groove is arranged on a circular arc surface on the mouth part of the cooker body; a rubber ring which can realize seal between the elastic disc and the cooker body is arranged on the elastic disc. When the pressure limiting valve is blocked and pressure in the cooker increases, the elastic disc can drive the rubber ring to move upwards, and the pressure releasing groove can automatically release oversize pressure in the cooker. The utility model has the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of family expenses pressure cooker, particularly a kind ofly can effectively prevent its blast, guarantee personal safety, and family expenses pressure cooker simple in structure.
Existing family expenses pressure cooker mostly adopts three safety devices, i.e. pressure limiting valve and anti-block apparatus, safety valve and cover closing and opening safety device.Its weak point be safety device very little, the passage of part safety device is less and darker, thereby, usually occur causing when processing food of different nature or maloperation food to stop up safety device, finally make pressure cooker surpass normal pressure and blast.So people design and manufacture the pressure cooker of four, five, six safety devices again, its weak point one is that safety device is still less, still not enough security insurance; The 2nd, increase many annexes, make the structure of pressure cooker complicated, maintenance is made troubles to long-time maintenance.
The purpose of this utility model provides a kind of safety device many at above-mentioned weak point exactly, can effectively prevent its blast, guarantee personal safety, and Safety pressure cooker simple in structure.
Technical solution of the present utility model is: a kind of Safety pressure cooker, comprise a pot body, pot cover and pressure limiting valve, and it is characterized in that: on the inner face of pot cover, be provided with a resilient disc.On the arc surface of pot body oral area, be provided with pressure relief groove.Be provided with on the resilient disc realize its with pot body between the rubber ring that seals.
Rubber ring described in the utility model technical solution can be fixed on the crimping of resilient disc.
Pressure relief groove described in the utility model technical solution can be the following narrow wide arc conical surface of.
The utility model is owing to be provided with resilient disc and rubber ring on the pot cover inner face, at pot body mouth along locating to be provided with the dozens of pressure relief groove, thereby, when pot inner pressure is in nominal pressure, resilient disc is subjected to the effect of specified air pressure, drive rubber ring and upwards make certain displacement, but also do not reach pressure relief groove, the pressure limiting valve of this moment is remaining normal duty.When pressure limiting valve is blocked for some reason, the interior pressure of pressure cooker surpasses nominal pressure, resilient disc is exceeded the quata to decide the effect of air pressure, drive that rubber ring is upwards done the super large displacement and when reaching pressure relief groove, the pot internal gas pressure is discharged in pressure relief groove immediately automatically, and the pressure relief groove of this moment just plays the effect that is equivalent to the dozens of safety device, can shed the super large pressure portion in the pot automatically, jeopardize safe dangerous situation thereby removed, ensured personal safety conscientiously.Because the shape of a fairly large number of pressure relief groove is the narrow down wide arc conical surface of, along with pressure increases, rubber ring moves on constantly, and the pressure relief groove section is constantly increased, and having can not the property stopped up, and it is minimum to make pressure cooker the possibility of explosion danger occur.The utility model also has characteristics simple in structure, easy to use, thereby has reached its intended purposes.
Fig. 1 is a structural representation of the present utility model.
The utility model is described in further detail below in conjunction with Fig. 1: as shown in the figure.Pot body 1, pot cover 2 is all identical with existing pressure cooker with pressure limiting valve 5.Difference: the one, at fixed waveform resilient disc 4 on the inner face of pot cover 2 and be fixed on rubber ring 3: two on the waveform resilient disc 4, on pot body 1 oral area cambered surface, have many (being 24～48) pressure relief groove 6.Waveform resilient disc 4 can be stretched by stainless steel material and make, and its edge forms crimping, and rubber ring 3 just in time hangs on this crimping.Pressure relief groove 6 is narrow down wide, and is the arc conical surface, and pressure relief groove 6 also can be other shape.
