Description

A kind of pressure cooker lid of quick pressure releasing

Technical field

The utility model relates to pressure cooker lid, and a kind of pressure cooker lid of quick pressure releasing particularly belongs to the improvement technology of pressure cooker.

Background technology

In order to guarantee the safety of pressure cooker, safety guard is set on pot cover all generally.When in the pressure cooker pot pressure being arranged, pot cover can not be opened.But, when culinary art finishes, quick-opening lid soon often because the pressure in the pot does not reduce.In order to address this problem, generally all be through pushing pressure limiting valve aside with hand, steam being discharged from blast pipe, in operating process, hand is scalded by the liquid of steam or ejection easily.Also have on pot cover, to be provided with manual exhaust apparatus, but when the long-time exhaust of needs, need to push with hand always or promote manual exhaust apparatus, have inconvenient operation, also exist and set about easily by the potential safety hazard of the liquid of steam or ejection scald.

Summary of the invention

The purpose of the utility model is in order to address the above problem, and a kind of pressure cooker lid of simple in structure, safe and convenient to use, quick pressure releasing that cost is low is provided.

The technical scheme that realizes the utility model purpose is: a kind of pressure cooker lid of quick pressure releasing; Pot cover is provided with pressure limiting valve and position-limit mechanism; Said pressure limiting valve comprises the pressure limiting valve seat that is fixed on the pot cover and is nested with the pressure limiting valve body that has shifting block on the pressure limiting valve seat; It is characterized in that: in said position-limit mechanism, be provided with movable push bar, the front end of push rod is resisted against the shifting block side of pressure limiting valve body.When promoting push rod, the front end of push rod promotes shifting block, and the pressure limiting valve body is risen along the inclined-plane slide unit in the pressure limiting valve seat, and pressure limiting valve loses sealing function, realizes the quick pressure releasing exhaust.

Be with reposition element on the above-mentioned push rod, position-limit mechanism carries out spacing to reposition element.

Above-mentioned reposition element is a spring.

The cross section of above-mentioned position-limit mechanism is down " L " type or traverse " n " font.

Above-mentioned pot cover is provided with the push rod detent mechanism, and this detent mechanism is to be arranged on the other block of push rod, and corresponding with block, the push rod tail end is provided with the handle of setting.When level promotes push rod forward and makes pressure limiting valve pressure release exhaust, the handle of rotation push rod, handle contacts with the push rod detent mechanism, makes push rod be positioned in and promotes to realize lasting pressure release exhaust on the pressure limiting valve pressure release exhaust position.

Above-mentioned push rod detent mechanism can be processed one with position-limit mechanism.

For the globality that guarantees pressure cooker lid and the aesthetic property of outward appearance, also be provided with cover on the above-mentioned pressure cooker lid, position-limit mechanism and push rod detent mechanism are fixed on the cover; Perhaps position-limit mechanism and push rod detent mechanism are fixed on handle of pot lid on hand.

The operation principle of the utility model: when level promoted push rod, push rod contacted with pressure limiting valve, and promoted the pressure limiting valve body, pressure limiting valve is no longer sealed, thereby reach the purpose of quick pressure releasing.Promote push rod for a long time for fear of the user, can be when promoting push rod, the handle on the rotation push rod, and being affiliated on the push rod detent mechanism on the pot cover, thus reach laborsaving safe, the effect that continues the pressure release exhaust.

The beneficial effect of the utility model is: promote the technical scheme that the pressure limiting valve body carries out the quick pressure releasing exhaust owing to designed push rod; Stop that the consumer directly stirs the air bleeding valve body and the potential safety hazard of scalding the consumer; The utility model is simple in structure, with low cost; Under the condition of exhaust mode that does not change product and product appearance, the structure that has reached expensive complicacy reaches the effect same of effective and safe pressure release, adaptable across various pressure cooking products and voltage power culinary products.

The specific embodiment

Below in conjunction with the Figure of description and the specific embodiment the utility model is further described.

Like Fig. 1, shown in Figure 2, a kind of pressure cooker lid of quick pressure releasing,pot cover 1 are provided withpressure limiting valve 2 and position-limit mechanism 6; Saidpressure limiting valve 2 comprises the pressure limiting valve seat that is fixed on thepot cover 1 21 and is nested with the pressure limitingvalve body 22 that has shiftingblock 221 on pressure limitingvalve seat 21, and pressure limitingvalve seat 21 inwalls are provided with the inclined-plane slide unit, and pressure limitingvalve body 22 bottom surfaces are positioned on the inclined-plane slide unit; At said position-limit mechanism 6 is an inner cavity body; Be provided withmovable push bar 3 in its cavity, be withreposition element 4 on thepush rod 3,reposition element 4 adopts spring; The cross section of above-mentioned position-limit mechanism 6 is down " n " font of " L " type or traverse, and 6 pairs of reposition elements of position-limit mechanism 6 carry out spacing.The front end ofpush rod 3 is resisted against shiftingblock 221 sides of pressure limitingvalve body 22; Also be provided with pushrod detent mechanism 5 on the above-mentionedpot cover 1, thisdetent mechanism 5 is for being arranged on the block onpush rod 3 sides, and corresponding with this block,push rod 3 tail ends are provided with thehandle 31 of setting.Above-mentioned pushrod detent mechanism 5 can be processed one with position-limit mechanism 6.

For the globality that guaranteespressure cooker lid 1 and the aesthetic property of outward appearance, also be provided with cover on the above-mentionedpressure cooker lid 1, position-limit mechanism 6 is fixed on the cover with pushrod detent mechanism 5; Perhaps position-limit mechanism 6 and push roddetent mechanism 5 are fixed on handle of pot lid on hand.

When needs pressure release exhaust; As shown in Figure 4, level promotes thehandle 31 on thepush rod 3, after the front end ofpush rod 3 passes the position-limit mechanism 6 that is traverse " n " font on thepot cover 1; The front end ofpush rod 3 promotes shiftingblock 221; Pressure limitingvalve body 22 is risen along the inclined-plane slide unit in the pressure limitingvalve seat 21, andpressure limiting valve 2 loses sealing function, realizes the quick pressure releasing exhaust.When the user needs long-time exhaust, throughrotary handle 31 and be affiliated on push roddetent mechanism 5, just can the pushing time promote push rod, and keep lasting pressure release exhaust.Pressure limiting valve belongs to prior art in the pressure cooker in the present embodiment, therefore, is not giving unnecessary details here.

As shown in Figure 3, when needs seal culinary art, with thehandle 31 back-out push roddetent mechanisms 5 ofpush rod 3; Reset response through the reposition element on the push rod 34;Push rod 3 is automatically reset, and under the effect of pressure limitingvalve body 22 self gravitations, pressure limitingvalve body 22 descends along the inclined-plane slide unit in the pressure limitingvalve seat 21;Pressure limiting valve 2 recovers sealing function, thereby reaches the effect of sealing culinary art.

The above only is the preferred embodiment of the utility model, is not that the structure of the utility model is done any type of restriction.Every technical spirit according to the utility model is made any simple modification to above case study on implementation, and equivalent variations and modification all fall in the protection domain of the utility model.
