The pressure switch proposed according to embodiments of the present invention and electric pressure cooking saucepan described with reference to the accompanying drawings.
Fig. 1 is the overlooking structure diagram of the pressure switch of the application one embodiment.
Such as Fig. 1, pressure switch 10, comprising: the first contact 11, the second contact 12 and magnet assembly 13.
Wherein, the first contact 11 and the second contact 12 are oppositely arranged along first direction；The magnetic field side that magnet assembly 13 generates
It is greater than zero to the angle between first direction, magnet assembly is for changing the arcing electric current between the first contact 11 and the second contact 12
Direction.Angle between magnetic direction and first direction that Fig. 1 is generated with magnet assembly 13 is 90 degree and is illustrated.
Specifically, pressure switch 10, can be various types of pressure switches, for example, flame-proof type pressure switch, machinery pressure
Power switch, electron pressure switch etc..
Magnet assembly 13 can be the component that can arbitrarily generate magnetic field, for example, permanent magnet, hot-wire coil etc..Fig. 1
Illustrated so that magnet assembly 13 includes the first permanent magnet 131 and the second permanent magnet 132 as an example.
Wherein, the first permanent magnet 131 is opposite with the magnetic pole of the second permanent magnet 132；First permanent magnet 131 and the second permanent magnet
132 are oppositely arranged in a second direction, and the angle between second direction and first direction is greater than zero.
It is 90 degree in Fig. 1 with the angle between second direction and first direction to be illustrated.In addition, N north-seeking pole, S refer in Fig. 1
The South Pole, the magnetic direction that magnet assembly 13 generates are the direction that N is directed toward S.
Specifically, arcing sense of current is first party when generating phenomenon of arc discharge between the first contact 11 and the second contact 12
To, i.e. horizontal direction in Fig. 1, the angle between the magnetic direction and first direction that are generated due to magnet assembly 13 is greater than zero, because
There is magnetic-field component in this, to can produce the ampere being not zero under the influence of a magnetic field in a direction perpendicular to the first direction
Power.The direction of Ampere force is vertical with arcing electric current and magnetic direction, so as to change arcing sense of current, by arcing distance
Elongation has the function that fast arc extinction, realizes the protection to contact, extends the service life of pressure switch.
In a kind of preferably way of realization, the magnetic direction that magnet assembly 13 generates can hang down mutually with first direction
Directly, i.e., as shown in Figure 1, the first permanent magnet 131 and the second permanent magnet 132 can be opposite along the second direction perpendicular to first direction
Setting so as to so that the Ampere force generated is maximum, and then makes the speed of arc extinguishing faster.
In a kind of possible way of realization of the present invention, as shown in Fig. 2, magnet assembly 13 can be electrified wire 133.
Wherein, electrified wire 133 and the first contact 11, the setting of the second contact 12 in same plane and the first contact 11 with
Second contact 12 is located at the ipsilateral of electrified wire 133.The right side of the first contact 11 and the second contact 12 is arranged in electrified wire by Fig. 2
Illustrated for side.
Specifically, can produce when the direction of the electric current I of electrified wire 133 is direction shown in arrow in Fig. 2 from paper
Outside magnetic field.When generating phenomenon of arc discharge between the first contact 11 and the second contact 12, if arcing sense of current is the first touching
The direction of 11 the second contact 12 of direction of point then under the influence of a magnetic field can produce Ampere force vertically downward, to change drawing
Arcing distance is elongated and has the function that fast arc extinction by the direction of arc current.
It should be noted that electrified wire 133 can according to need setting same with the first contact 11 and the second contact 12
One plane and the first contact 11 and the second contact 12 can be made to be located at the ipsilateral any position of electrified wire 133.For example, can set
It sets in position as shown in Figure 2, also can be set with the first contact 11 and 12 same plane of the second contact and positioned at the first touching
The position in the left side of point 11 and the second contact 12；Alternatively, can be set with 12 same plane of the first contact 11 and the second contact,
And it is located at the position of downside, etc. of the first contact 11 and the second contact 12.
It further, can also include controller in pressure switch 10, for according to the electric current flowed through in pressure switch 10
The current value of electrified wire 133 is flowed through in value, control.
Specifically, if it is determined that can then increase when the current value flowed through in pressure switch 10 is larger and flow through electrified wire 133
Current value；If it is determined that then can reduce the electric current for flowing through electrified wire 133 when the current value flowed through in pressure switch 10 is smaller
Value.
It is understood that in general, the magnetic field size of the generation of electrified wire 133 and the electric current for flowing through electrified wire 133 are big
It is small directly proportional.When the current value flowed through in pressure switch 10 is larger, the drawing that is generated between the first contact 11 and the second contact 12
Arc current is also corresponding larger, and the current value of electrified wire 133 is flowed through by increasing, the magnetic field that electrified wire 133 can be made to generate
It is stronger, to generate bigger Ampere force, and then make the speed of arc extinguishing faster.When the current value flowed through in pressure switch 10 is smaller
When, the arcing electric current generated between the first contact 11 and the second contact 12 is also corresponding smaller, leads at this point it is possible to reduce and flow through energization
The current value of line 133, to can reduce the consumption of energy while guaranteeing the effect of fast arc extinction.
It further, in embodiments of the present invention, can also include power supply, for providing electric current for electrified wire 133.
In addition, in embodiments of the present invention, can also include current monitoring component, flow through pressure switch 10 for monitoring
Electric current, so that controller can control the electric current for flowing through electrified wire 133 according to the size of current of current monitoring assemblies monitor
Value.
Wherein, current monitoring component can be the component for arbitrarily capableing of monitoring current.For example, mutual inductor, current sensor
Deng.
In addition, as shown in figure 3, can also include pressing component 14 in pressure switch 10, under pressure by the
One contact 11 and 12 connection of the second contact or disconnection.
It should be noted that Fig. 3 is the forward sight structural schematic diagram of pressure switch 10, component 14 is pressed shown in Fig. 3
Shapes and sizes only schematically illustrate, and in specific implementation, the shapes and sizes for pressing component 14 can according to need progress
Setting, herein with no restriction.
Specifically, press the pressure that component 14 can be acted on downwards, if it is smaller to press the pressure that component 14 is subject to, or
There is no pressure to act on to press on component, then the first contact 11 in pressure switch and the second contact 12 are by pressing component 14
It is logical；If it is larger to press the pressure that component 14 is subject to, pressing component 14 can be moved down, to make the first contact 11 and second
Contact 12 is in an off state, and is acted on according to pressure by the first contact 11 and 12 connection of the second contact or disconnection to realize.
Pressure switch provided by the embodiments of the present application, including the first contact, the second contact and magnet assembly, the first contact and
Second contact is oppositely arranged along first direction, and magnet assembly can produce the magnetic field that the angle between first direction is greater than zero, into
And the Ampere force vertical with first direction is generated, when can generate phenomenon of arc discharge between the first contact and the second contact, changes and draw
