Abstract
The utility model relates to a petal-type non-explosion pressure cooker. All elevations of the exterior margin of the pressure cooker lid besides a curved tooth part and the installation position of an upper handle are gradually and symmetrically provided with outwards convex arc-shaped dummy clubs like petal, thus a sealing ring has a deformed space under an excessive pressure condition, as a result, the lip edge is separated from the mouth of the cooker to decompress and prevent explosion. The utility model has multiple explosion-proof constructions, while the shape is very simple. Other shapes and sizes of the pressure cooker are not altered, and therefore, the utility model has high universality and beautiful appearance.
Description
The utility model relates to a kind of pressure cooker, the not quick-fried pressure cooker of a plurality of outside protrusion shapes of particularly a kind of pot cover outer rim facade such as petal.
Application has a kind of not quick-fried pressure cooker at present, and it is the sealing ring overvoltage to be set eject the chamber on pot cover, with this pot that ejects the relevant position, chamber pressure relief opening is being set on one's body.This pressure cooker blast resistance construction is single, poor reliability; Be provided with eject chamber shape and sealing ring overvoltage the time the actual shape difference that ejects bigger, and design corner angle arranged, not slick and sly, not attractive in appearance; Pot pressure relief opening associative perception on one's body is poor, and can influence the service life of pot mouth and sealing ring.
The purpose of this utility model is to provide a kind of improved a plurality of blast resistance constructions that have, the not quick-fried pressure cooker that features of shape is simple and attractive in appearance again.
The utility model is achieved in that a kind of pot cover of not quick-fried pressure cooker, outer rim at it is not on all facades at curved tooth position, the arc boss of outside protrusion all is set, upper handle can be installed in the curved tooth position of pot cover, if upper handle is installed on the pot cover outer rim facade that is not curved tooth position, then on this facade an arc boss can be set less.The utility model is provided with arc boss on the facade of pot cover outer rim, its layout is well-balanced according to the curved tooth quantity calibration of pot cover; Its degree of depth is adjusted to pressure cooker can make sealing ring successfully outwards outstanding in arc boss under overvoltage condition, and tears this lip limit, place disengaging pot mouthful pressure release, can make the sealing ring at arc boss place have sealing again under normal working pressure.This arc boss is provided with separately, needn't join work with shapes such as sealing ring and pot mouths, can realize explosion-proof purpose.
The utility model blast resistance construction is many, and shape is but simple especially, and it is except the arc boss of making symmetrical shape such as petal on pot cover, and other geomery of pressure cooker does not all change, product highly versatile, good looking appearance.
The embodiment that provides below in conjunction with accompanying drawing does further detailed narration to the utility model.
Fig. 1 is the structural representation of the utility model open pot cover time the inside.
Fig. 2 is the amplification view of A-A among the utility model Fig. 1.
Fig. 3 is the vertical view of the utility model Fig. 2.
On a kind of outer rim of pot cover (5) of not quick-fried pressure cooker, neither curved tooth position (3) neither all the other all facades of upper handle (4) installation position on, the arc boss (2) of the outside protrusion that joins with pot cover (5) step surface all is set.When pot inner pressure is excessive, the outer rim (6) of sealing ring (1) just outwards is out of shape protrusion, enter in the inner chambers of arc boss (2) of pot cover (5), and the lip limit (7) of tearing the sealing ring (5) at this place breaks away from the pot mouthful (8) of pot body (9), let out the explosion-proof purpose of vapour step-down thereby reach.
Claims (3)
1. a petal-shaped not quick-fried pressure cooker is characterized in that: on outer rim all the other all facades except that curved tooth position (3) and upper handle (4) installation position of pot cover (5), be provided with the arc boss (2) of the outside protrusion that joins with pot cover (5) step surface.
2. petal-shaped not quick-fried pressure cooker as claimed in claim 1 is characterized in that: all arc boss (2) on the pot cover (5) all are to be provided with separately, needn't join work with the shape of sealing ring (1), pot mouthful (8), can realize explosion-proof purpose.
3. as claim 1 and 2 described petal-shaped not quick-fried pressure cookers, it is characterized in that: arc platform (2) is that calibration is well-balanced according to the curved tooth quantity of pot cover (5).
