The utility model is achieved through the following technical solutions:
A kind of electric pressure cooker, pot body that comprises upper end open, in pot body, the heat-generating disc assembly is housed, interior pot is housed above the heat-generating disc assembly, described pot body opening part be hinged with can with the loam cake that has pressure relief device of interior pot interruption-forming sealing, it is characterized in that: last cover be provided with and the body of stewing on the normal hook that fastens of lid button, cover on described and also be provided with the safety switch group that can in pot, can open hook under the safe pressure.
Aforesaid a kind of electric pressure cooker, it is characterized in that described safety switch group comprises that outer button, button inner core and restriction hook upper end move down the limited block of stroke, be provided with limit power elastic component outside described between button and the button inner core, the hook upper end is withstood in button inner core lower end.
Aforesaid a kind of electric pressure cooker is characterized in that described hook is hinged on to cover, and is provided with normally closed reduction torsion spring between hook and the loam cake.
Aforesaid a kind of electric pressure cooker is characterized in that being provided with the torsion spring 5 that loam cake can be flicked between described pot body and loam cake.
Aforesaid a kind of electric pressure cooker is characterized in that described outer button is hinged on to cover, and is provided with reduction torsion spring between described outer button and the loam cake.
Aforesaid a kind of electric pressure cooker is characterized in that described limit power elastic component is a force-limit spring.
Aforesaid a kind of electric pressure cooker is characterized in that the described limit power elastic component power shell fragment that exceeds.
Aforesaid a kind of electric pressure cooker is characterized in that described limited block is arranged on the below of outer button and is one with it.
Compared with prior art, the utility model has following advantage:
The utility model is provided with the safety switch group; if there be dangerous interior the pressure in pot; need big elastic force to press the hook upper end; and the button inner core is in limited block contact stop position; can not be with opening of hook under the elasticity of compression power effect of force-limit spring or limit power shell fragment; play the effect of safeguard protection; loam cake only can be opened under the safe pressure in pot; eliminate electric pressure cooker and when opening, may cause fast ejection and cause the potential safety hazard of security incident of thermal current; safe in utilization, convenient, simple in structure.

[specific embodiment]
A kind of electric pressure cooker, pot body 1 that comprises upper end open, in pot body 1, heat-generating disc assembly 2 is housed, pot 3 in above heat-generating disc assembly 2, being equipped with, described pot body 1 opening part be hinged with can with the loam cake that has pressure relief device 401 4 of interior pot interruption-forming sealing, between pot body 1 and loam cake 4, be provided with the torsion spring 5 that loam cake can be flicked, be provided with on the loam cake 4 and the body 1 of stewing on the button 201 normal hooks 6 that fasten of uncapping, also be provided with the safety switch group 7 that can in setting safe dynamics, open hook 6 on the described loam cake 4.Described safety switch group 7 comprises outer button 8, button inner core 9, and limits the limited block 11 that hook 6 upper ends move down stroke, and described limited block 11 is arranged on the below of outer button 8 and is one with it.Be provided with limit power elastic component 10 outside between button 8 and the button inner core 9, the hook upper end is withstood in button inner core 9 lower ends, and outer button 8 is provided with limited block 11.Hook 6 is hinged on the loam cake 4, is provided with normally closed reduction torsion spring 12 between hook 6 and the loam cake 4.Described elastic component 5 is a torsion spring.Described outer button 8 is hinged on the loam cake 4, is provided with reduction torsion spring 13 between outer button 8 and the loam cake 4.Described limit power elastic component 10 is force-limit spring or limit power shell fragment.
In the time of need opening electric pressure cooker loam cake 4, press outer button 8, outer button 8 is delivered to button inner core 9 by the elastic force of limit power elastic component 10, button inner core 9 is pressed the upper end of lower draw-bar 6, hook 6 is around hinge swing, and the elastic force that overcomes frictional force between the lid button 201 at hook 6 and pot body 1 fastening place and normally closed reduction torsion spring 12 breaks away from lid and detains 201 and loam cake is opened.If do not press in having in pot, normal pressure between the rubbing surface 601 of hook 6 and the lid button 201 is less, the frictional force of then linking up with 6 rubbing surface 601 and covering between the button 201 is less, then button inner core 9 is not when limited block 11 contacts stop position 15, under the elasticity of compression power effect of force-limit spring or limit power shell fragment 10, hook 6 can be opened, after unclamping hand, outer button 8 is resetted by reduction torsion spring 13.If in pot interior pressure is arranged; the rubbing surface 601 of hook 6 and the normal pressure of uncapping between the button 201 are bigger; the frictional force of then linking up with 6 rubbing surface 601 and uncapping between the button 201 is bigger; then button inner core 9 is when limited block 11 contact stop positions 15; failing will to link up with 6 under the elasticity of compression power effect of force-limit spring or limit power shell fragment 10 opens; need bigger power hook 6 could be opened; and this moment, limited block 11 was stoped continuation compression force-limit spring or limit power shell fragment 10 by stop position 15; can not open hook 6; can not open under the situation that loam cake 4 is pressed in having, play the effect of safeguard protection.
When closing loam cake 4, will link up with 6 by normally closed reduction torsion spring 12 and reset and lid button 201 fastenings.The utility model is provided with safety switch group 7, and 4 of loam cakes can be opened under the safe pressure in pot, has eliminated electric pressure cooker and may cause thermal current ejection and cause the potential safety hazard of security incident fast when opening, and is safe in utilization, make things convenient for, simple in structure.
