Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan, particularly relates to a kind of electric pressure cooking saucepan pot cover black box.
Background technology
The pot cover of existing electric pressure cooking saucepan directly is buckled on the outer pot mouth, and realizes the sealing of pot inner pressure by sealing ring.
Patent 200320119448.2 discloses a kind of hermetically-sealed construction of electric pressure cooking saucepan.Wherein, sealing ring is suspended on the pot cover inner surface periphery by a steel ring that is fixed on the pot cover inner surface, and the steel ring inside circumference is provided with two support foots, two support foots and the welding of pot cover inner surface.In this technical scheme, sealing ring inner ring sidewall is provided with the groove of a circle engagement steel ring, and steel ring fixes sealing ring by the interference fit with the sealing ring inboard groove.Therefore, when pot inner high voltage state, thereby sealing ring pressurized and expanded by heating are come off by the steel ring outside.In addition, steel ring is welded on the pot cover, is not easy to remove to clean.
The utility model content
The purpose of this utility model provides a kind of electric pressure cooking saucepan pot cover black box of sealing ring difficult drop-off.
The purpose of this utility model is achieved in that
A kind of electric pressure cooking saucepan pot cover black box comprises pot cover, sealing ring and sealing ring garter spring, and described sealing ring outer ring sidewall is provided with a circle groove; One of described engagement is fixed on the sealing ring garter spring on the pot cover inner surface.
In order to guarantee that the sealing ring garter spring dismantles easily, can further realize by following technical proposals.
Described sealing ring garter spring and described pot cover flexibly connect.
Described sealing ring garter spring outer circumference is provided with two above ears, the mutual clamping of boss of described ear and pot cover inner surface.
In order to keep the sealing of sealing ring, described sealing ring inner ring is provided with circle " U " type groove.
Compared with prior art, sealing ring garter spring of the present utility model is arranged on the outer ring of sealing ring, and by sealing ring outer ring sidewall be provided with one the circle engagement.When at pot inner high voltage state, sealing ring is subjected to compression swelling, thereby can be combined in more closely on the sealing ring garter spring, is difficult for coming off from the sealing ring garter spring.In addition, the sealing ring garter spring is movably connected on the pot cover, realizes by the mutual clamping of the boss of the ear that is provided with on the sealing ring garter spring and pot cover inner surface, and is for convenience detach, cleans easily.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the a-quadrant enlarged drawing;
Fig. 3 is a sealing ring garter spring plane;
Fig. 4 is the sealing ring profile.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 2, a kind of electric pressure cooking saucepan pot cover black box comprises pot cover 3, sealing ring 1 and sealing ring garter spring 2; Described sealing ring 1 outer ring sidewall is provided with a circle groove 6; Sealing ring garter spring 2 of described groove 6 engagements; Described sealing ring garter spring 2 is provided with two above ears 4, and boss 5 clampings on described ear 4 and the pot cover make sealing ring garter spring 2 and pot cover 3 to flexibly connect.
When having pressure in the pot, sealing ring 1 expands under air pressure towards periphery, makes sealing ring 1 be combined in more closely on the sealing ring garter spring 2, makes sealing ring 1 be not easy to come off.
When electric pressure cooking saucepan does not use, can dismantle lower seal garter spring 2 and sealing ring 1.Therefore clean easily, easy to use.
