It closes in cavity volume, wherein one end of insulated column is connected to the compression spring on piece blown out outside boss, and the other end of insulated column is connected to
On elastic plate mechanism, it is particular in that and downward shrapnel is provided on the free end of elastic plate mechanism, the free end setting of shrapnel
There is inside gib head, corresponded on reservoir body bottom surface and button is provided at gib head, unhook structure is provided in reservoir body.It in use, will
The utility model is fixed on pressure electric appliance, and the free end of compression shrapnel is leaned against on pressure cooker bottom, is increased with the pressure of pressure cooker
Greatly, the bottom of a pan dilatancy drives the movement of compression shrapnel, and then insulated column is driven to move down, and pushes elastic plate mechanism, makes shrapnel machine
Contact on structure is detached with the contact in fixed contact, so as to have the function that pressure stroke switch, when the interior temperature of pressure cooker
Degree is beyond set temperature, so that compression shrapnel continues to move to, and then drives insulated column to move down, pushes elastic plate mechanism, makes
Gib head on elastic plate mechanism reaches the position of button and is hooked in when buckling, even if the Wen Duxiajiang of pressure cooker, compression shrapnel can not
Elastic plate mechanism is driven to reset by insulated column using its screen resilience, until user is determining troubleshooting, pressure cooker can restore
During normal use, gib head can be made to be detached from the effect of button by unhook structure, in this way, pressure switch is with regard to that can restore its original work(
Energy.
Here, unhook structure includes piercing into the pull rod in reservoir body, in closing cavity volume and the lasso that is driven by pull rod,
Lasso is sleeved on shrapnel.In use, lasso is moved relative to shrapnel, detained on gib head hook so that shrapnel can drive, need gib head from button
During upper disengaging, by pull rod drive lasso be moved to the outside, lasso then drive gib head from buckle be detached from.Lasso is used, in this way, bullet
Piece can just be moved up and down in lasso in a free state along lasso, do not influence shrapnel and gib head is driven to be hooked in and buckle.
Alternatively, it is the movable block of taper that unhook structure, which is end, towards detaining, calm cavity bottom pierces into movable block and it is bored
The conical surface of shape end is against gib head.In use, movable block is made to be buckled in this way, gib head just can be successfully hooked in far from button, need hook
When being detached from button, movable block is made to be moved toward button, taper surface and the gib head of cone-shaped end relatively move, and gib head is squeezed out to the effect of button
Range, so as to which gib head be made to be detached from the effect of button.
Alternatively, be provided with vertical guide groove in the middle part of shrapnel, unhook structure include it is out of cavity is pierced into side cavity and
Shank across guide groove, positioned at shank end volume hook.In use, shank opposed guide slots move, so that shrapnel can drive gib head hook
Upper button needs gib head from when buckling disengaging, hook is driven to be moved to the outside by shank, hook then by the shrapnel that pulls outward make gib head from
Buckle disengaging.
Compared with the prior art, it is can preventing external environmental and with overpressure protection self-locking to have for the utility model
Advantage.
