Abstract
The utility model relates to an explosion-proof pressure-cooker comprising a pan body and a pan cover which are engaged with each other, a sealing ring is disposed between the pan body and the pan cover which are separately provided with a crank, and a discharge pipe is disposed on the pan cover, wherein the discharge pipe is provided with a weight-loaded style pressure control valve. The discharge pipe is arranged on a cover board, the pan cover is provided with an opening hole which is sealed by the cover board, a cover board shade is connected with the pan cover, and an elastic element is arranged between the cover board and the cover board shade which is provided with an air gate. When the pressure in the pressure-cooker rises to a setting limiting value, function of the pressure causes the cover board to overcome the elastic force of the elastic element, the cover board is jacked upward to form backlash between the cover board and the pan cover opening hole, steam is discharged outside via the backlash, the utility model has explosion-proof function, thereby being safer to be used.
Description
Technical field:
The utility model relates to a kind of explosion-proof pressure pot.
Background technology:
Existing pressure cooker generally is made of pot body, pot cover and handle.As Chinese patent a kind of " safety anti-explosive pressure cooker cover " just proposed for No. 99209540.9, in this technical scheme, pressure cooker cover is formed by being installed in outlet nozzle, sealing ring on the pot cover and the pressure limiting valve that cooperates with outlet nozzle, pot cover is connected into the integral body that has interlayer by inside and outside lid, outlet nozzle is fixed on the inside and outside of interlayer place with securing member and covers, the outer passage in addition that covers at interlayer place.When the pore on Anti-stop cover or the outlet nozzle is blocked, after the pressure cooker internal pressure rises to the limiting value of setting, make upwards jack-up of inner cap distortion by the pressure effect, make and form a gap between outlet nozzle and inner cap, steam enters interlayer by the gap and discharges by the passage that covers outward, reaches the pressure release purpose.But have the following disadvantages:
1, because of pot cover connects into the integral body that has interlayer by inside and outside lid, outlet nozzle is fixed on the inside and outside of interlayer place with securing member and covers, the outer passage in addition that covers at interlayer place, and its complex structure is made inconvenient.
2, after the inner cap distortion once of pressure cooker, the distortion meeting build-up of pressure pot of inner cap can't reuse.
3, after the improper pressure release of pressure cooker, the dirt in the interlayer can't be cleared up, and makes the inner cap can't normal deformation work.
Summary of the invention:
The purpose of this utility model is: a kind of explosion-proof pressure pot simple in structure, safe in utilization is provided.
The utility model is achieved through the following technical solutions:
A kind of explosion-proof pressure pot, comprise: the pot body and the pot cover that cooperatively interact, be provided with sealing ring between pot body and pot cover, be respectively equipped with handle on pot body and the pot cover, pot cover is provided with blast pipe, blast pipe is provided with the Weight type pressure limiting valve, it is characterized in that: described blast pipe is located on the cover plate, and pot cover is provided with the pot cover perforate, the perforate of cover closure pot cover, plate cover is connected on the pot cover, is provided with elastic component between cover plate and plate cover, and plate cover is provided with venthole.
Advantage of the present utility model is: after the pressure cooker internal pressure rises to the limiting value of setting, the pressure effect makes cover plate overcome the elastic force of elastic component, the cover plate jack-up that makes progress, make between cover plate and pot cover perforate and form the gap, steam discharges by the gap, make to the utlity model has explosion prevention function, use safer.Because described blast pipe is located on the cover plate,, make the utility model structure more simple with the perforate of cover closure pot cover.After the pressure cooker pressure release, cover plate can seal the pot cover perforate automatically under the effect of elastic component, even after making that pressure cooker of the present utility model carried out improper pressure release, it is just reusable also to need not to change parts.And cover plate and pot cover tapping clean very convenient.
In the utility model, described elastic component is a spring.Adopt spring can realize cover plate is applied certain pressure, make pressure cooker when operate as normal, the perforate of cover closure pot cover.
In the utility model, described elastic component is a reed.Adopt reed can realize cover plate is applied certain pressure, make pressure cooker when operate as normal, the perforate of cover closure pot cover.
In the utility model, be provided with sealing ring between described cover plate and pot cover perforate.Sealing ring can make pressure cooker when operate as normal, and cover plate seals the pot cover perforate reliably.
In the utility model, described blast pipe below is provided with Anti-stop cover.It can prevent that blast pipe is blocked.
