Description

A kind of electric pressure cooking saucepan exhaust apparatus

Technical field

The utility model relates to the electric pressure cooking saucepan technical field, especially a kind of safety exhaust unit of electric pressure cooking saucepan.

Background technology

The electric pressure cooking saucepan of existing structure generally all can be equiped with exhaust apparatus on pot cover; Electric pressure cooking saucepan is when operate as normal, and its air bleeding valve is in sealing state.When steam pressure in the electric pressure cooking saucepan pot surpassed its limit value, air bleeding valve can discharge gas automatically, guaranteed that the electric pressure cooking saucepan steam pressure is no more than safe pressure; On the other hand, when pressure being arranged in the electric pressure cooking saucepan pot and need open pot cover, will earlier the steam in the pot be discharged from exhaust apparatus outside the pot manually.

At present, when electric pressure cooking saucepan needs manual exhaust, normally directly the valve body of air bleeding valve is mentioned exhaust, user's hand is because near steam vent, therefore the high-temperature gas scald that is discharged from easily, exists very big potential safety hazard; For this reason, also useful can not self-sustaining hand push type exhaust or switching regulator exhaust structure, when can not self-sustaining hand push type exhaust apparatus wanting continuous exhaust pneumatic wallop, hand will press ﹠ hold always, operate very inconvenient, and the switching regulator exhaust apparatus, can make air bleeding valve be in two stable status, be exhaust and sealing state, the switching regulator exhaust structure of this structure, though overcome can not self-sustaining hand push type exhaust apparatus deficiency, the user often forgets after exhaust makes exhaust apparatus be returned to sealing state, when cooking next time, can become the non-pressure culinary art.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of hand not need the long button also can continuous exhaust pneumatic wallop, and can be after the exhaust through the operation of folding lid, exhaust apparatus can be returned to the safe and convenient electric pressure cooking saucepan exhaust apparatus of sealing state voluntarily.

The purpose of this utility model is to adopt following technical measures to solve:

A kind of electric pressure cooking saucepan exhaust apparatus, pot cover includes enclosing cover and inner cap, inner bag places on the outer pot, inner cap is arranged on the upper opening of inner bag, described outer covering is equiped with air bleeding valve, air bleeding valve comprises valve rod, valve body and conical needle constitute, have the exhaust passage that atmosphere is connected with inner bag on the valve rod, conical needle is arranged on the valve body, valve body is sealed in the exhaust passage exhaust outlet with the deadweight form by conical needle and is installed in valve rod top, cover outward and also be equiped with an exhaust button, cover bottom portion is passed in exhaust button lower end, the below of cover bottom portion also has additional a lever, lever is provided with fulcrum, lever one end extends to exhaust button lower end, its other end is provided with the push rod that can touch valve body, described outer covering also is equiped with the fastening knob, fastening knob is made up of knob lid and knob base, the knob lid anchors on knob base top, knob base is installed in outer covering with rotation formula, also be provided with middle cover between enclosing cover and the inner cap, middle cover is provided with the convex driving member, the circular arc sidewall sleeve of knob base bottom is gone in the groove on convex driving member top, lever one end inserts convex driving member sidewall, the exhaust button is located at knob and is covered, exhaust button lower end is successively passed knob lid and knob base and is stretched to lever one end that inserts in the convex driving member, described convex driving member bottom also is fixed with the fastening connecting rod, fastens connecting rod and is provided with when rotating the fastener that pot cover and outer pot can be fastened mutually.The electric pressure cooking saucepan of said structure, its air bleeding valve can be in four kinds of states respectively: the sealing state when, working; Two, superpressure exhaust condition; Three, the non-tight state of pot cover when not exclusively fastening; Four, the metastable state during artificial exhaust.

The purpose of this utility model can also adopt following technical measures to solve:

Concrete structure as push rod, described push rod comprises and is interconnective touch-control cross bar of whole shape and vertical supporting rod, the touch-control cross bar is located at enclosing cover top and is extended to valve body lower end, the vertical supporting rod lower end links to each other with lever one end, the other end passes enclosing cover and the touch-control cross bar joins, and vertical supporting rod also is with the push rod back-moving spring.The design of the touch-control cross bar of push rod, guaranteeing valve body jack-up, and the push rod back-moving spring on the vertical supporting rod is provided with, and then can make push rod after losing impetus power, automatically resets rapidly.

The lower end of described exhaust button also is with exhaust button back-moving spring.

Described fastener can be to be fastened between the inner cap and outer pot of pot cover, and certainly, fastener also can be according to designing requirement, and fastener is with the inner cap of pot cover and the fastening of inner bag.

For making things convenient for the setting of balance pivot, balance pivot covers in can being arranged on.

This practical beneficial effect is:

Electric pressure cooking saucepan exhaust apparatus of the present utility model by air bleeding valve and exhaust button are set at pot cover, and divide both and is arranged, and the exhaust button is by the exhaust of lever assembly control air bleeding valve; Manually during exhaust, because the exhaust button is away from the exhaust outlet on the steam vent, the high-temperature steam that the operator is difficult for being discharged from is scalded, and has very high security; Moreover the exhaust button is controlled air bleeding valve by lever, and user's hand will be grown the operation inconvenience of button when having solved artificial exhaust; When non-safety fastens, make air bleeding valve be in the non-tight state at pot cover, increase security; Moreover after the artificial exhaust, through the operation that the opening and closing lid fastens, air bleeding valve is got back to sealing state voluntarily.
