Description
Technical field
The present invention relates to electric cooker technical field, more particularly to a kind of electric cooker contact switch.
Background technology
At present, the operation principle of electric cooker on the market is：When starting to cook, with hand pressure lower switch button, its permanent magnet
With the suction of temperature-sensing magnetic body phase, after hand unclamps, button no longer recovers, then the contacting of electric cooker electric shock switch, and electric hot plate, which is powered, to be added
Heat, after boiling water, due to kept in pot 100 DEG C it is constant, therefore temperature-sensitive magnet is still attracting with permanent magnet, continues to heat, until meal is ripe
Afterwards, moisture is absorbed by rice, and cooking bottom temperature rise, when temperature rises to " 103 DEG C of curie point ", temperature-sensitive magnet loses ferromagnetism,
Under the action of the spring, permanent magnet is flicked, and contact separation, is cut off the electricity supply, so as to stop heating.And current, existing electric cooker
The contact of electric shock switch is separately positioned on spring leaf and in fixed touch plate, spring leaf easily fails using after a period of time,
Cause contact sparking (arcing) problem.
The content of the invention
The purpose of the present invention is exactly to provide a kind of simple in construction to solve the deficiency of prior art, can strengthen reality
Existing contact break-make speed has more decisiveness, so as to solve original contact sparking problem, improves reliability and the adjustable electric in life-span
Pot for cooking rice contact switch.
The present invention is to realize above-mentioned purpose using following technical solution：A kind of adjustable electric pot for cooking rice contact switch,
Characterized in that, it includes contact holder and the screw rod, the upper stator of spaced setting, the lower stator that set thereon, on
There is ceramic washer one to separate between stator, lower stator, and be fixed on by screw rod on contact holder, passed through on upper stator
Fastener is connected with spring leaf, and mutually corresponding contact is respectively arranged with lower stator and spring leaf；By upper stator with
Spring plate group into the compound arm of force, enhancing realizes that contact break-make speed has more decisiveness, and connecting and disconnecting were all completed at 0.5 second,
So as to solve original contact sparking (arcing) problem, reliability and life-span are improved.
As a further illustration of the above scheme, screw jacket is provided with insulator, there are ceramics between contact holder and stator
Packing ring two compartment, ceramic washer three is provided with above upper stator.
Further, the top of fixed is provided with the top pressure arm of force, is fixed with the top pressure arm of force and upper stator
The thimble that top pressure coordinates.
Further, the lug plate being connected with upper stator is fixed with the screw rod.
Further, the end set of fixed has indent, and screw is provided with indent, has screw will in screw
Spring leaf is fixed on the lower section of stator, no longer needs pincers worker mode to adjust switch bridge during pipelining, it is only necessary to special
Screwdriver can be carried out have adjusted.
Further, the contact is solder contacts, reduces contact resistance, improves conveyance capacity.
The beneficial effect that the present invention can be reached using above-mentioned technical solution is：
1st, the present invention uses upper stator and spring leaf combined connecting structure, is the compound arm of force from the enhancing of the simple arm of force, leads to
The enhancing for crossing the arm of force realizes that contact break-make speed has more decisiveness, so as to solve original contact sparking problem, improve reliability with
Life-span.
2nd, contact technologic improvement:Riveting contact is changed to solder contacts, reduces contact resistance, improves conveyance capacity.
3rd, switch realizes controllability in itself, no longer needs pincers worker mode to adjust switch bridge during pipelining, it is only necessary to
Speical screwdriver can be carried out have adjusted.

Embodiment
The technical program is explained in detail below in conjunction with specific embodiment.
As shown in Figure 1-Figure 3, the present invention is a kind of adjustable electric pot for cooking rice contact switch, and it is including contact holder 1 and thereon
The screw rod 2 of setting, the upper stator 3 of spaced setting, lower stator 4, have ceramic washer between upper stator, lower stator
One 5 separate, and are fixed on by screw rod on contact holder, and spring leaf 7, lower stator are connected with by fastener on upper stator
Be respectively arranged with spring leaf mutually corresponding to contact 6, contact is solder contacts, reduce contact resistance, improve conveyance capacity；
By upper stator and spring plate group into the compound arm of force, enhancing realizes that contact break-make speed has more decisiveness, connecting and disconnecting
All completed at 0.5 second, so as to solve original contact sparking (arcing) problem, improve reliability and life-span.Porcelain is arranged with outside screw rod 2
Set, there is the separation of ceramic washer 28 between contact holder and stator, ceramic washer 39 is provided with above upper stator.It is described
The lug plate 10 being connected with upper stator is fixed with screw rod.The end set of upper stator has indent 3-1, is provided with indent
Screw 3-2, there is the lower section that spring leaf is fixed on upper stator by screw in screw, no longer needs pincers worker mode during pipelining
