As shown in Figures 1 to 5, it is specially oven gate controlled switch according to the gate controlled switch in the present embodiment, is mounted on oven
Main body on, specifically can be when door body 80 be opened, in gate controlled switch for obtaining a switch state of oven door 80
The state that door body 80 is opened is fed back to controller by trigger switch 20, and controller cuts off heat-generating pipe power-off, user is avoided to be burned,
It is electrically shocked.Certainly, the gate controlled switch in the present embodiment does not limit to applied to oven, be also possible to be applied to refrigerator, micro-wave oven,
Electric steam box etc. for obtaining a switch state of door body 80, and switch state can be exported.
Gate controlled switch in the present embodiment includes mounting shell 10, trigger switch 20, driving member 30 and bias piece.Specific touching
Hair switch 20 is mounted on mounting shell 10, and the switch contact 21 of triggerable trigger switch 20 is provided in trigger switch 20；Transmission
Part 30 is movably disposed on mounting shell 10, and has the first working position for abutting switch contact 21 to trigger trigger switch 20
Set and far from switch contact 21 the second operating position；Bias piece and driving member 30 cooperate, and have so that driving member 30 is in
The biasing force of first operating position；Wherein, for driving member 30 when door body 80 is closed, door body 80 drives driving member 30 to overcome biasing force
Far from 21 to the second operating position of switch contact.And then the gate controlled switch in the present embodiment is in the switch state for obtaining door body 80
When, make driving member 30 in the first working position for abutting switch contact 21 by the biasing force of bias piece when door body 80 is opened the door
It sets, and is overcoming biasing force to work far from switch contact 21 to the second by the effect power drive driving member 30 of door body 80 at closing time
Position, compared with the existing technology in the active force of door body 80 directly act on switch contact 21, due to bias piece biasing force more
Add stabilization, it can be ensured that switch contact 21 can be pressed, and will not make at closing time trigger switch 20 by biggish power,
The service life of gate controlled switch is improved, the detection of 80 folding condition of door body is relatively reliable, stablizes.
Bias piece in the present embodiment is the elastic component abutted respectively with driving member 30 and mounting shell 10, more specifically spring
40, driving member 30 abuts switch contact 21 under the elastic force of elastic component, and the signal that trigger switch 20 exports at this time is door body 80
The signal of opening.Certainly, bias piece may be magnetic element, and the elastic force phase with spring is provided by the magnetive attraction of magnetic element
Similar magnetive attraction.Trigger switch 20 is specially microswitch, has the advantages that high sensitivity, but can also have stress mistake
Defect easy to damage when big, and its gate controlled switch of application in this present embodiment, can overcome microswitch to lead when stress is excessive
Cause the defect of entire gate controlled switch damage.
Mounting shell 10 in the present embodiment includes bottom case and cover board, and driving member 30 is slidably disposed on bottom case and/or lid
In plate, and then the triggering of the different switch states of gate controlled switch is realized in different sliding positions.Certainly, driving member 30 can also be with
It is to be rotatably arranged on shell, in different turned positions, gate controlled switch equally may be implemented in different switch states
Triggering.
As shown in Figures 2 to 5, sliding slot 11 is offered by taking driving member 30 is slidably arranged on bottom case as an example, on bottom case, is passed
Moving part 30 can slide in sliding slot 11, and spring 40 is arranged between driving member 30 and the side wall of bottom case.It is in and beats in door body 80
When open state, spring 40 is under the elastic force effect of spring 40, driving member 30 to be pushed to press fine motion in compressive state always
The switch contact 21 of switch.Meanwhile the gate controlled switch in the present embodiment is provided with limiting stand 13 on mounting shell 10, in spring 40
When pushing driving member 30, driving member 30 is abutted with limiting stand 13, and limiting stand 13 can limit the forward stroke of driving member 30, so that
Trigger switch 20 can avoid excessive stress while realizing push switch contact 21 under the active force of spring 40, further mention
The reliability for having risen gate controlled switch improves the service life and user experience of gate controlled switch.
As shown in Figure 3 and Figure 4, when door body 80 is in close state, door body 80 will push driving member 30 and slide inward, make it
It is detached from switch contact 21, spring 40 is further compressed.The flexible stroke of elastic component is greater than driving member 30 the in the present embodiment
Movement travel between one operating position and the second operating position, so that in the case where door body 80 completely closes, transmission
Part 30 can also continue to move the stroke that a value is X inward, and the presence of this stroke can be to avoid in the feelings of certain rigging error
Under condition, door body 80 is gated switch and withstands and can not close, or gate controlled switch top is bad, further improves in the present embodiment
The reliability of gate controlled switch, the detection of 80 folding condition of door body is relatively reliable, stablizes.
As shown in figure 5, to driving member 30 in this present embodiment, driving member 30 includes trigger unit, the door at closing time of door body 80
Body 80 drives trigger unit so that driving member 30 overcomes biasing force mobile, and specific driving member 30 forms in trigger unit protrudes from peace
The latch structure 31 that shell 10 is arranged is filled, latch structure 31 and driving member 30 are integrally formed, so that total is more reliable.And
Oven door body 80 at closing time, latch structure 31 is abutted by door body 80 and then makes 30 stress of driving member mobile, and then is realized
The triggering of trigger switch 20.Driving member 30 in the present embodiment further includes avoiding structure 33, in driving member 30 far from switch contact
To avoid trigger switch 20 during 21 to the second operating positions, so that driving member 30 can smoothly overcome the active force of spring 40
To the second operating position, the interference with other structures in 80 structure of door body is avoided, so that the reliability of gate controlled switch is more preferably.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes among the protection scope created still in the utility model.
