Abstract
A pressure relieving structure of an electric pressure cooker comprises a cooker body, a heating plate, an elastic sheet, a driving sheet, an adjusting bolt, a driving lever and a circuit switch, wherein a connecting body is arranged in the middle of the heating plate and fixed on the elastic sheet at the bottom of the cooker body; the elastic sheet is in contact with the driving sheet; the adjusting bolt is arranged below the driving sheet, penetrates through the driving lever and is matched with the driving lever; and one unfixed end of the driving lever is in contact with the circuit switch. During use, the heating plate is stressed to sink and the connecting body is enabled to compress the elastic sheet and the driving sheet, so that the driving sheet moves and ejects up the adjusting bolt, the adjusting bolt drives the unfixed end of the driving lever to move down and the circuit switch is turned off to disconnect a pressure cooker circuit. In order to solve shortcomings in the prior art, the utility model provides the electric pressure cooker with accurate control, safety and reliability; as a non-self-resetting circuit switch is arranged at the bottom of the cooker body, the pressure can be relieved in time when overlarge pressure is available in the cooker body, so that the safety of the electric pressure cooker in use is guaranteed and the service life of a product is prolonged.
Description
Technical field
The utility model relates to a kind of pressure relief of electric pressure cooking saucepan.
Background technology
Electric pressure cooking saucepan is because easy to operate, safe in utilization the liking of users that receive deeply always.At present, electric pressure cooking saucepan commonly used is when cooking, and when its internal pressure rises to when exceeding set pressure, safety valve can be opened automatically, and gases at high pressure are discharged from steam vent then; When the air pressure in the pressure cooker dropped to normal pressure, safety valve can cut out automatically.But safety valve was in case lost efficacy, and pressure cooker just is easy to the danger of blasting.Chinese patent document number CN2815215 has announced a kind of electric pressure cooking saucepan releasing pressure automatically safety guard that resets on September 13rd, 2006; Comprise pressure switch, pressure adjusting lever, first liner plate, connector, back-moving spring and adjusting bolt, an end of pressure adjusting lever and the contact of pressure switch lean.This design springs back to original state through back-moving spring after the pressure cooker pressure release is accomplished, make outer courage can not produce excessive deformation and product and after pressure release, still can continue to use.But the back-moving spring easy ageing distortion of this scheme makes it operating safety factor and reduces, and therefore, is necessary to do further improvement.
The utility model content
The purpose of the utility model aims to provide a kind of pressure relief of simple and reasonable, safe and reliable electric pressure cooking saucepan, to overcome the weak point of prior art.
Press the pressure relief of a kind of electric pressure cooking saucepan of this purpose design; Comprise a pot body, heat-generating disc, shell fragment, driving chip, adjustment screw, activation lever and contactor, its architectural feature is that said heat-generating disc middle part is provided with connector, and connector is fixed on the shell fragment of bottom of pot body; Shell fragment contacts with driving chip; Driving chip below has adjustment screw, adjustment screw to pass activation lever and match with it, and the loose end of activation lever contacts with contactor.
The below, bottom of said pot body is equipped with support, and an end of support is provided with hinge hole, and an end of activation lever is provided with the articulated section, cooperates with hinge hole an end of activation lever is fixed.
Said adjustment screw is passed the middle part of activation lever, and the top of adjustment screw contacts with driving chip.
Said contactor is the lock switch of non-automatic-reset, and this lock switch is the protruding jumping temperature controller of hand-reset formula that removes the bimetallic thermal sensitive piece.
The utility model is for solving the deficiency of prior art; Designed a kind of accurate, safe and reliable electric pressure cooking saucepan of controlling; Through the bottom at the pot body non-automatic-reset switch is set, venting pressure timely when pot body internal pressure is excessive is not so that a pot body produces excessive distortion; Simultaneously also guarantee the safe in utilization of electric pressure cooking saucepan, prolonged the service life of product.
Description of drawings
Fig. 1 is the utility model one example structure sketch map.
Fig. 2 is an embodiment cutaway view.
Among the figure: 1 is the pot body, and 2 is heat-generating disc, and 2.1 is connector, and 3 is shell fragment, and 4 is driving chip, and 5 is support, and 5.1 is hinge hole, and 6 is activation lever, and 6.1 is the articulated section, and 7 is adjustment screw, and 8 is lock switch.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 2, a kind of pressure relief of electric pressure cooking saucepan comprises pot body 1, heat-generating disc 2, shell fragment 3, driving chip 4, adjustment screw 7, activation lever 6 and contactor.Heat-generating disc 2 middle parts are provided with connector 2.1, and connector is fixed on the shell fragment 3 of pot body 1 bottom, and shell fragment contacts with driving chip 4, and there is adjustment screw 7 the driving chip below, and the top of adjustment screw contacts with driving chip 4.Below pot body 1 bottom, being provided with support 5, matches with the hinge hole 5.1 of support 5 in the articulated section 6.1 of activation lever 6, and an end of activation lever is fixed on the support; Adjustment screw 7 is passed activation lever 6 and is matched with it, and the loose end of activation lever contacts with lock switch 8, and this lock switch is the protruding jumping temperature controller of hand-reset formula that removes the bimetallic thermal sensitive piece.In use; Air expanded by heating in the pot body 1 causes the sinking of heat-generating disc 2 pressurizeds and makes connector 2.1 compressing shell fragments 3 and driving chips 4, and driving chip moves and jack-up adjustment screw 7; Under the drive of adjustment screw; Activation lever 6 loose ends are along doing arcuate movement with a hinged end of support 5 and move down, thereby make the circuit of lock switch 8 actions and off voltage power pot, and electric pressure cooking saucepan stops heating.
