Abstract
The utility model relates to a safety pressure cooker. The working holes of the cooker lid and the cooker body thereof are both elliptical. The pressure cooker is designed into an inner-lid-typed pressure cooker, and namely, the cooker lid is positioned in the cooker body and is covered by a cooker lid upper pulling rod and a cooker body upper connecting rod through buckling members. When the utility model is used, the greater the pressure in the cooker is, the more tightly the cooker lid is pressed on the cooker body, and the better the sealing is. The accident that the cooker lid flies away can not occur, and so, the safety pressure cooker is very safe. Because the contacting surface of a sealing ring in the groove of the cooker lid and the hot steam is small, and when the cooker lid is opened or closed, no friction exists between the cooker lid and the cooker body, not only the sealing ring is not easily aged, which extends the service life of the sealing ring, but also the sealing effect is better.
Description
The utility model relates to a kind of pressure cooker, particularly a kind of safe pressure cooker.
Usually; the pressure cooker that uses in the daily life is the enclosing cover formula; lock portion mostly adopts the rotary body biting connecions between pot cover and the pot body; rubber seal in the lid is V-shaped; this structural pressure pot is after one section use; regular meeting causes degree of blocking not enough because of reasons such as wearing and tearing; the lighter does not reach seal request; also can produce sliding phenomenon when serious; cause pot cover to fly to collapse and hurt sb.'s feelings; owing to seal ring of pressure cooker only is to rely on the V-shaped part to be heated to open to reach sealing; and sealing ring regular meeting sustains damage because of friction and elastic tape is worn out by high heat effect during the folding pot cover; so make sealing ring not reach the sealing that sealing function also can influence pressure cooker; want to reach seal request and just need often to change sealing ring; will change the once sealing circle in the general 3-6 of this kind pressure cooker month according to statistics; this not only makes troubles to use, but also has increased spending.
The purpose of this utility model is to provide a kind of not only long service life, and the safe pressure cooker of good sealing effect.
Concrete solution is: pot cover all adopts ellipsoidal structure with the working hole of pot body, pressure cooker is designed to the inner cap formula, be that pot cover places in pot body, sealing ring places in the groove of pot cover and pot body contact site pot cover, and be connected with a pull bar on the pot cover, be provided with buckling piece between pull bar and the connecting rod, can finish covering and sealing between pot cover and the pot body by this structure, for promptly guaranteeing pressure cooker when work positiver sealing and safety, guarantee conveniently to open again to get pot cover, the major axis of pot body running mouth should be greater than pot cover minor axis 5-10mm, the binding site radial width is 18-22mm between pot cover and the pot body, and the sealing ring height is higher than depth of groove 1.5mm-2.5mm, and pot cover is provided with gas cap and fusible plug, when pot inner pressure and temperature rising, play depressurization.
The utility model is owing to adopt inner cap formula structure, makes press between the big more pot cover of pot inner pressure and pot body tight more, and it is good more to seal, and pot cover can not take place flies the accident of collapsing, and is as safe as a house.Again since sealing ring with the heat steam contact-making surface is less and do not have friction between pot cover and the pot body during folding pot cover, so not only sealing ring is difficult wears out, and has prolonged the service life (the sealing ring operating period can reach more than 3 years) of sealing ring and has made sealing effectiveness better.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model vertical view.
Fig. 3 is the utility model cover structure schematic diagram.
In the present embodiment, pot cover (9) is oval, and pot cover (9) is connected with a pull bar (4) by pillar (7), pot cover (9) is provided with groove with pot body (1) contact site pot cover, sealing ring (10) is arranged in the groove, also be provided with gas cap (6) and fusible plug (8) on the pot cover (9), when the pot inner pressure temperature surpasses regulation, play and back down and the fusing effect.Pot body (1) is cylindrical, and pot body running mouth is oval, and pot body (1) is gone up symmetry riveting short handle (11) and connecting rod (2), is fixed with a thimble (5) above the pot body of connecting rod (2) one sides and plays the tie-strut effect.Clasp (3) is a ring-type.Sealing ring top is evenly distributed with detent projection.
During use, the major axis (a) that pot cover (9) minor axis (b) can be aimed at pot body running mouth embeds (taking-up) pot body with pot cover, when covering, make the long and short axle of pot cover corresponding with the long and short axle of pot body, and pot cover is mentioned by pull bar (4), clasp (3) is fastened between pull bar (4) and the connecting rod (2), makes pot cover cover good seal, unclamp clasp when opening and pot cover can be taken out by pull bar rotation pot cover.And can utilize short handle (11) and the convenient pressure cooker that extracts of connecting rod (2).
Claims (4)
1, a kind of safe pressure cooker, comprise pot cover and pot body, the working hole that it is characterized in that pot cover (9) and pot body (1) is ellipse, pressure cooker is the inner cap formula, pot cover (9) can place in pot body, and pot body (1) is provided with connecting rod (2), and pot cover (9) is provided with pull bar (4), be provided with buckling piece (3) between pull bar (4) and the connecting rod (2), sealing ring (10) is positioned at pot cover outer rim groove.
2, safe pressure cooker according to claim 1 is characterized in that pot body running mouth major axis (a) should be greater than pot cover minor axis (b) 5--10mm, and the binding site radial width is 13-22mm between pot cover and the pot body.
