Description
Technical field
The present invention relates to a kind of pressure cut-off structure, more particularly to a kind of electric pressure cooking saucepan and its pressure cut-off device.
Background technology
Pressure cooker at work, due to that can cause internal pressure abnormal when its safety member fails, to realize its security,
Need to cut off heating power supply in time.
At present, the Publication No. CN203953296U of in the market Chinese patent discloses a kind of pressure switch, including：Open
Close seat；Shell fragment is touched, the shake-up shell fragment is the cantilever shape being located on the switch base；Pressure shell fragment, the pressure shell fragment
For the cantilever shape being located on the switch base, the pressure shell fragment is provided with movable contact；Stationary contact shell fragment, the stationary contact are
The cantilever shape being located on the switch base, the stationary contact shell fragment are located between the pressure shell fragment and the shake-up shell fragment,
And the stationary contact shell fragment is provided with the stationary contact relative with the movable contact, and the stationary contact often connects with the movable contact
Touch；The shake-up connecting rod that the pressure shell fragment can be promoted to make the movable contact be separated with the stationary contact, the shake-up connecting rod are located at
Between the pressure shell fragment and the shake-up shell fragment；Anti- reseting shrapnel, the anti-reseting shrapnel are configured in the movable contact
The pressure shell fragment is propped up when being separated with the stationary contact makes the movable contact and the stationary contact keep the shape separated.
Realization principle is：When pressure, which exceedes setting value, reaches the power-off pressure of pressure switch, touch connecting rod and promote pressure
Shell fragment, when pressure shell fragment deforms upon, the free end of movable contact shell fragment moves up, while movable contact and stationary contact separation, and
Movable contact shell fragment is across after anti-reseting shrapnel, and anti-reseting shrapnel is against on the lower surface of movable contact shell fragment, so that movable contact
Keep separating with stationary contact.
In such scheme, by the movement for touching connecting rod, movable contact and stationary contact be gradually disengaged, the process breaking speed compared with
Slowly, and then corresponding electrical connection can not be disconnected in time, potential safety hazard be present.
The content of the invention
The first object of the present invention is to provide a kind of pressure cut-off device of electric pressure cooking saucepan, and its advantage is that have quick disjunction
Movable contact, the ability of stationary contact electrical connection.
The present invention above-mentioned technical purpose technical scheme is that：A kind of pressure of electric pressure cooking saucepan is broken
Electric installation, including pedestal, the pedestal be provided with for electrically connect movable contact spring and static contact, the movable contact spring be provided with it is quiet
The flexure strip that contact elasticity contradicts；The pedestal is provided with swing component and the swing for rotating that linkage flexure strip separates with static contact
The reed of part clamping；The pedestal, which is provided with, to be used to promote swing component, reed is compressed the movable axis of critical point across it；It is described
Reed includes fixing end and actuation ends, and the pedestal is provided with the first fixture block and the first limited block for fixing end clamping, described
Swing component is provided with the second fixture block and the second limited block for actuation ends clamping.
Pass through above-mentioned technical proposal, movable axis promote swing component so that swing component produces rotation, and swing component makes spring when rotating
Elastic deformation occurs for piece, and in this process, reed gradually stores elastic potential energy, and swing component moves closer to flexure strip, when reed becomes
When near its compresses critical value, the further actuating spring of movable axis, reed is across after compressing critical point, reed release elastic potential energy connection
Movable pendulum moving part quick rotation, swing component are contradicted to flexure strip surface, promote flexure strip elastic deformation, while flexure strip and static contact
Depart from electrical connection；The linear moving process of movable axis is changed into the elastic potential energy storing process of reed by the process, when and
Only when reed is across during compression critical point, the elastic potential energy of reed is converted to kinetic energy, linkage swing component quick rotation so that electricity
Connection disconnects, and serves for electrical equipment and fast and accurately powers off, improves security；The fixing end of reed passes through two first
Fixture block and first limited block realize and gripped up and down that the actuation ends of reed are limited by two the second fixture blocks and one second
Position block is realized to be gripped up and down；During the quick rotation of swing component, reed improves reed by multiple spot fixation and put
Installation site accuracy on moving part, reduces the offset of reed, and the accuracy of corresponding electrical connection open position obtains
Improve.
The present invention is further arranged to：Including base, the base is provided with intake interface, for sealing intake interface
Sealing ring, the admission line communicated with intake interface is additionally provided with base.
Pass through above-mentioned technical proposal, the intake interface on base are available for steam to be passed through, because sealing ring is compressed by pedestal, gas
Body pressure can make sealing ring deformation, promote movable axis during sealing ring deformation；The kinetic energy of steam is converted to sealing ring by the process
Deformation process, and conversion ratio is higher, the deformation process of sealing ring is more directly perceived, pressure detecting of the intake interface equivalent to steam
Mouthful, realize the detection of steam pressure；And admission line is connected as attachment structure and more facilitated.
The present invention is further arranged to：Including the upper lid with base engagement, the upper lid is provided with close to the side of swing component

Upper lid 12 is provided with the set screw 16 being threadedly coupled with it, and set screw 16 is two, two set screws 16 and jointed shaft
15 both ends contradict, and keep the balance of jointed shaft 15, set screw 16 relatively upper 12 turn of lid when can be by the jointed shaft of swing component 5
15 push downwards along chute 14.If set screw 16 drives jointed shaft 15 to move down, swing component 5 is overall to be moved down, and then
Swing component 5 needs to rotate bigger angle to reach the compression critical point of reed 6, and corresponding movable axis 7 needs to pass groove
34 more length need bigger gas pressure intensity to promote sealing ring 10 to produce bullet to realize the rotational angle of swing component 5
Property deformation；To sum up, after set screw 16 is adjusted, gas pressure required during the electrical connection disjunction of pressure cut-off device can be changed
Value.
