Description
Technical field
The utility model belongs to kitchen small household appliances technical field, is specifically related to a kind of novel electric pressure cooking saucepan stopping valve.
Background technology
Present commercially available electric pressure cooking saucepan; generally be provided with stopping valve, exhaust valve component and relief valve assembly on the inner pot cover; the effect of stopping valve bar is can't uncap when producing pressure in the pot; it is the culinary art effect of control electric pressure cooking saucepan that exhaust valve component mainly acts on; control magnetic valve promotion ball valve comes exhaust when pot inner pressure surpasses the setting value of program; the effect of relief valve assembly is when the exhaust passage of exhaust valve component inefficacy or air bleeding valve is stopped up; action exhaust pressure relief when pot inner pressure surpasses operating pressure, the protection electric pressure cooking saucepan can not work the mischief because of hypertonia.Like this, a plurality of assemblies are just arranged on the inner pot cover, complex structure, make loaded down with trivial details, the cost height.
Summary of the invention
The purpose of this utility model is exactly in order to solve the deficiency of prior art, the electric pressure cooking saucepan stopping valve that provides a kind of stopping valve and safety valve to unite two into one, make on the inner pot cover part still less, be more convenient for installing.
The technical scheme that its technical problem that solves the utility model adopts is:
This electric pressure cooking saucepan stopping valve, comprise and be contained in the stopping valve seat that has through hole that covers in removable, be provided with the stopping valve bar that can slide up and down in the stopping valve seat, the bottom of stopping valve bar is embedded with the stopping valve rod seal circle that can seal stopping valve seat through hole, the top of stopping valve bar is provided with the stopping valve cap, and this stopping valve cap has air-vent; The centre of stopping valve bar is a through hole, is provided with push rod in through hole, is with back-moving spring on the push rod, and the bottom of push rod is embedded with the push rod sealing ring that can seal stopping valve bar bottom through-hole.When pot inner pressure during in normal operating pressure value, the stopping valve bar ejects removable inner cap because of the pressure effect, and formation can't be uncapped, and this moment, the push rod sealing ring was a sealing state.But the pressure in pot continues to rise, when surpassing the operating pressure of electric pressure cooking saucepan, the suffered pressure of push rod in the middle of the stopping valve bar moves up when surpassing the elastic force of spring, this moment, pot inner pressure can pass through the through hole of stopping valve bar bottom through the air-vent exhaust of push rod from the stopping valve cap, reduce the pressure in the pot, eliminate the potential safety hazard of electric pressure cooking saucepan.
Further, the stopping valve cap is threaded with the stopping valve bar.
The utility model beneficial effect mainly shows: the utility model stopping valve and safety valve unite two into one, part still less, assemble simpler, easier sealing, and manufacturing cost can be lower.

Description of reference numerals: removable inner cap 1, stopping valve bar 2, stopping valve cap 3, stopping valve rod seal circle 4, stopping valve seat 5, push rod 6, spring 7, push rod sealing ring 8, slide block sealing ring 9, slide block 10, the button 11 of uncapping, hook rotating shaft 12, hook 13, pot body assembly 14, cover assembly 15.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, the utility model comprises removable inner cap 1, stopping valve bar 2, stopping valve cap 3, stopping valve rod seal circle 4, stopping valve seat 5, push rod 6, spring 7 and push rod sealing ring 8, on removable inner cap 1, have through hole, stopping valve seat 5 is applied on the through hole, by riveted and fixed on removable inner cap 1.Stopping valve bar 2 is applied on the through hole of stopping valve seat 5, and can slide up and down.Be embedded with the stopping valve rod seal circle 4 that can seal stopping valve seat 5 through holes in the bottom of stopping valve bar 2.Stopping valve cap 3 has air-vent by being threaded in the top of stopping valve bar 2 on the stopping valve cap 3.Be provided with push rod 6 in the centre of stopping valve bar 2, be with spring 7 on the push rod 6, the bottom of push rod 6 is embedded with push rod sealing ring 8, and the centre of stopping valve bar 2 is a through hole, push rod 6 is close to the bottom of stopping valve bar 2 by the elastic force of spring 7, seals up the bottom through-hole of stopping valve bar 2.When pot inner pressure during in normal operating pressure value, stopping valve bar 2 can eject removable inner cap because of the pressure effect, and formation can't be uncapped.Push rod sealing ring 8 is sealing states at this moment.If the pressure in the pot continues to rise, when surpassing the operating pressure of electric pressure cooking saucepan, push rod 6 suffered upward pressures in the middle of the stopping valve bar 2 surpass moving up of spring 7 when down spring, this moment, pot inner pressure can pass through the through hole of stopping valve bar 2 bottoms through the air-vent exhaust of push rod 6 from stopping valve cap 3, reduce the pressure in the pot, eliminate the potential safety hazard of electric pressure cooking saucepan.
As shown in Figure 4, the operation principle that the restriction of stopping valve bar is uncapped is as follows: be provided with the slide block 10 of an activity on the liner of electric cooker cover assembly 15, slide block 10 can slide front and back on the cover liner.Hook 13 is located on the cover assembly 15 by hook rotating shaft 12.Slide block 10 front ends are the inclined-plane, and the rear end is embedded with the slide block sealing ring 9 that can seal slide block.When pressing when uncapping button 11, the button 11 of uncapping can be pushed down hook 13, makes hook 13 by hook rotating shaft 12 rotations, thereby makes hook 13 break away from pot body assemblies 14, thereby uncaps.Be similarly the inclined-plane of a protrusion on hook 13 top, the inclined-plane of slide block 10 can be pushed down in the inclined-plane of hook 13 when uncapping, thereby slide block 10 is moved to the centre.If meal pot is in work, in the time of can producing pressure in the pot, stopping valve bar 2 can be because the pressure effect ejects removable inner cap 1.If press shift knob 11 this moment, hook 13 slide blocks of pushing down 10 can be because the ejecting of stopping valve bar 2, and influences the stroke of slide block 10 and can't move, thereby reach the purpose that can't uncap.When simultaneously also only the pressure in pot is reduced to certain force value, when stopping valve bar 2 drops on the removable inner cap 1 because of self weight,, stopping valve bar 2 can uncap thereby can't influencing the stroke of slide block.
