Description
Technical field
The utility model relates to the kitchen utensils electric pressure cooking saucepan, specifically a kind of electric pressure cooking saucepan deflation structure.
Background technology
After existing electric pressure cooking saucepan heating work is finished, because kettle temperature is higher, before opening pot cover, sometimes need the operator pressure limiting vent valve to be mentioned or rotate and carry out exhaust with hand, the vapor (steam) temperature that sprays during exhaust can reach more than 100 ℃, because operating grip just on pressure limiting vent valve valve body, causes the risk that exists hand to be scalded in the operating process.Scald risk for solving, the electric pressure cooking saucepan that has is with the structural change of pressure limiting vent valve, make it manually can rest on certain position after the rotation, ceaselessly venting, but there is following inconvenience in it: and the user need manually mention the pressure limiting vent valve or rotate in use, this kind closely operated, have the danger of the steam scald that is ejected, and the user is in use as forgetting that electric pressure cooking saucepan is pressurized operation normally with the playback of pressure limiting vent valve.
The utility model content
The purpose of the utility model technology is at above-mentioned the deficiencies in the prior art, a kind of electric pressure cooking saucepan deflation structure is provided, adopt long-range venting, can be on the basis of satisfying electric pressure cooking saucepan quick pressure releasing in the short time, also have anti-scald function, the time of opening pot cover is shortened greatly, and the pressure limiting vent valve can self-return, prevent pressure limiting vent valve non-homing, electric pressure cooking saucepan can't operate as normal.
The technical scheme that realizes the utility model purpose is, a kind of electric pressure cooking saucepan deflation structure, comprise pressure limiting exhaust apparatus that is installed on the pot cover and the venting manipulation device that is installed on the pot cover, it is characterized in that: the pressure limiting exhaust apparatus is chewed by pressure limiting air bleeding valve and pressure limiting exhaust and is formed, the pressure limiting air bleeding valve drops on the pressure limiting exhaust according to deadweight and chews on the mouth, the venting manipulation device is by the venting button that is installed on the pot cover handle, the lever drive link and the slip jacking block that are installed in handle set are formed, venting button lower end is connected with an end of drive link, and the slip jacking block that is positioned at pressure limiting air bleeding valve below places the other end of drive link.
The utility model electric pressure cooking saucepan deflation structure, be installed in the distance that has a lever drive link between venting button on the pot cover handle and the pressure limiting air bleeding valve, the operator is downwards by the venting button, press the lever drive link, move on the other end lifting slip jacking block of drive link, move on the slip jacking block and move on continuing behind the contact pressure limiting air bleeding valve, the pressure limiting air bleeding valve leaves the pressure limiting exhaust and chews and realize long-range venting purpose.Because the venting button is chewed away from exhaust, can reduce the chance that danger is scalded in exhaust takes place.
As better scheme:
The utility model electric pressure cooking saucepan deflation structure can be also to be provided with return spring between said venting button and drive link, or place the other end of drive link also to be provided with slip jacking block return secondary spring at said slip jacking block, or these two kinds of technical schemes are implemented simultaneously.Be provided with that spring is favourable to press down under the venting button state in inoperation, the slip jacking block falls to resetting and breaks away from the pressure limiting vent valve, and the pressure limiting vent valve falls under the deadweight effect, drops on the pressure limiting exhaust and chews and reach the effect of positiver sealing gas on the mouth.
The utility model electric pressure cooking saucepan deflation structure can also be that venting button lower end is to be connected with drive link galianconism end, and the slip jacking block that is positioned at pressure limiting air bleeding valve below is to place on the drive link long arm end.During bleed air operation, drive link is a multiplying lever mechanism, and Operational Figure Of Merit improves.
The utility model electric pressure cooking saucepan deflation structure can also be provided with the security protection screen between venting button that is provided with on the handle and pressure limiting air bleeding valve.Can prevent more effectively that the steam that sprays from scalding the operator.
The utility model electric pressure cooking saucepan deflation structure is that the operator utilizes finger presses venting button pressed downwards drive link galianconism, lifts the slip jacking block on drive link is long-armed, and the open pressure limiting exhaust of slip jacking block jack-up pressure limiting air bleeding valve is chewed, and realizes long-range (drive link length) venting; After venting finished, finger discharged the venting button, relied on the elastic force of return spring and pressure limiting vent valve gravity to make button and the playback of pressure limiting vent valve, and the slip jacking block breaks away from long-armed whereabouts of drive link and pressure limiting vent valve, and the pressure limiting vent valve cuts out the pressure limiting exhaust and chews.Because operating point has with a certain distance from gas vent, can reduce and scald dangerous chance of occurrence, on the other hand, drive link adopts multiplying lever, can improve operational sensitivity.One slip jacking block return secondary spring is installed between slip jacking block and drive link, is guaranteed the better return of pressure limiting vent valve, increase mechanism reliability.
