Description

A kind of Kick type pressure control device
Technical field
The utility model belongs to family for kitchen use electro-technical field, is specifically related to a kind of pressure control device of realizing kick.
Background technology
Electric pressure cooking saucepan is energy-conservation with it, during joint, convenience and practicality become one of indispensable cooker of people's daily life.
The pressure control that cooker uses in the prior art, common the employing fixedly push rod of heat-generating disc touch sheet with the elasticity that is located at the heat-generating disc bottom, and this pressure control device is installed comparatively complexity of adjusting, limited adjustment range.China utility model patent CN01257731.6 open " a kind of automatic pressure pot ", it is made up of parts such as shell, inner cover, interior pot, heat-generating discs, heat-generating disc places the inner cover bottom, be evenly distributed with between heat-generating disc and the inner cover bottom and realize interior pot and inner cover elastic supporting mechanism, this elastic supporting mechanism main body is an elastic metal sheet, the middle part of metallic plate is fixed on the strut angle of heat-generating disc, and the micro-control switch of pressure control device is positioned on the feet.By interior pot of ever-increasing pressure, heat-generating disc is pushed downwards, the position of sheet metal correspondence is out of shape downwards, the end that heat-generating pipe is relative produces to bottom offset, until disconnecting the pressure control switch, interior pot is no longer heated boost.Though this patent can realize the purpose of automatic Regulation, the deformation of its metallic plate is linear poor, in actual applications, again because its flexible displacement is very little, and resetting property is poor, thereby pressure control inaccuracy, also exist simultaneously need with outer pot material property and size on uniformity; The requirement height of electric hot tray machining accuracy, manufacturing cost is very high.
China utility model patent CN2503818Y, a kind of pressure controller of electric pressure cooker that directly utilizes the work of pressure signal control heater is provided, form annular seal space by pot cover, interior pot and sealing ring, and be provided with the cylinder that is communicated with annular seal space, piston is housed in the cylinder, and the piston rod at rear portion is with spring, the piston rod displacement, permanent magnet on it and the permanent magnet on the switch key are inhaled from effect, reach the cut-out of heater switch or reset.This electric pressure cooking saucepan control device is arranged on the pot cover, reduces by the pressure controller manufacturing cost of piston with relative this patent disclosure of pressure signal feedback.But by the displacement touch switch action of piston rod, the pressure control rate is slow, and pressure controling precision is not high, is difficult to make pressure cooker accurate setting to adjustable in pressure control scope when cooking food.
The utility model content
The utility model purpose provide a kind of simple in structure, cost is low, the reliable and high Kick type pressure control device of precision of easy to use, pressure control.
The utility model realizes that above-mentioned purpose adopts following scheme:
A kind of Kick type pressure control device, place the handle of electric cooking appliance, include steam-operating part and control valve, the steam-operating part places sleeve to be slidingly matched with it, control valve and steam-operating part interlock is characterized in that also being provided with flexible member, lever, flap, are fixed on magnet steel and tongue tube under the flap; One end of flexible member relies on lever, and the other end is fixed in the horizontal level with the fulcrum of lever, and between the lower surface and steam-operating part of control valve, the other end and flap contact with lever one end of fulcrum rotation.
Kick type pressure control device described in the utility model, an end of flexible member is fixed on the handle, or be fixed in other affixed parts of handle on; The other end of flexible member contacts the boss (spring base) at lever or is directly fixed on lever, the fixing point of flexible member can with the fulcrum of lever at same horizontal line, when the lever rotation, compression elastic element, just be in same horizontal dynamic equilibrium state up to lever and flexible member, this moment, flexible member was to compress the most tightly in the impulse stroke, and the slight rotation of lever can destroy dynamic equilibrium state, lever is pressed down suddenly by the storage elastic force of flexible member, has realized the kick of lever.
The fulcrum of lever can be fixed in handle or shell, is lever and the handle or the pin joint of shell; Fulcrum also can be for being arranged on the small embossment of lever bar portion, be fixed with lever seat on the handle, flexible member one end leans the boss at lever, and the other end is seated at the boss of lever seat, and the pretightning force of flexible member is seated at the fulcrum of regulations and parameters on the lever seat in the corresponding draw-in groove.
Above-mentioned control valve includes bonnet, control valve spring, spool and valve seat, and valve seat and bonnet are affixed, and control valve spring is located between spool and the bonnet.
Also be provided with swing arm and lifters between above-mentioned bonnet and the valve spring, swing arm is that cam is connected with lifters, valve seat is fixed in handle, has the stopper slot that limits the lifters up-downgoing on the cylindrical shell of valve seat, stretches out with adjusting pressuring knob in the hole of bar portion by bonnet top of swing arm to be connected.
When stirring adjusting pressuring knob, swing arm is along with the identical angle of rotation, because swing arm adopts cam mechanism to be connected with lifters, lifters can only be up and down along control valve seat, the elemental height of control valve spring is shortened or elongation, the steam-operating part needed pot inner pressure difference of same displacement that rises reaches a pressure in the control pot with this, realizes the adjustable in pressure of electric pressure cooking saucepan.
Along the circumferential direction uniform one or more than one step on the described swing arm, lifters contacts with the step end face of swing arm with the projection that symmetry makes progress.
Described sleeve is provided with cushion rubber outward, can improve the good seal of device, improves precision.
Described flexible member is the elastic arc sheet or is the compression spring of spirality or butterfly.
One end horizontal-extending of described lever, horizontal segment and flap contact or removably connect with connector, flap can move up and down or rotation so that magnet steel triggers or disconnect tongue tube.
When electric pressure cooking saucepan used, when steam pressure in the pot rose, vapour pressure promoted the steam-operating part, drove the steam valve spool and rose, and when rising to certain altitude, lever is horizontal, and at this moment, lever and flexible member are in same horizontal dynamic equilibrium state just; Rise when the spool continuation, because the effect of flexible member, lever can be realized kick at this moment, thereby drives flap and the magnet steel activity that is positioned under it, touch switch; When pot inner pressure descended, the effect of control valve spring descended spool, because spool heads on lever, this moment, lever separated with flap gradually, from and gauge tap is replied, restart, can make thus to keep certain pressure in the pot.
The Kick type pressure control device that the utility model provides has following beneficial effect with respect to prior art:
(1), the pressure controling mode of Kick type, simple in structure, assemble easy to usely, pressure control is reliable, action is clear-cut, drift value is little, the precision height.
(2), by the swing arm that is provided with in the control valve and the cam structure setting of elevating lever, that realizes pressure has level adjustable.
(3), the component materials of control element is less demanding, can reduce material cost.
