Description
Technical field
The utility model relates to the pressure cooker manufacturing technology, and what especially relate to a kind of pressure cooker only drives safety device.
Background technology
Existing pressure cooker generally is provided with pressure limiting valve, stopping valve, safety valve respectively, stopping valve by valve rod, valve seat, only open tongue piece, only open part, spring is formed, valve rod is suspended on the valve seat; Only opening the upper end of part and only open tongue piece and link to each other, matches with guide groove on the lower handle in the bottom, and spring is located between the middle part and upper handle of only opening part.When pot body and pot cover fasten when not in place, only open part and under the effect of spring, make and only open the rising that tongue piece blocks valve rod, as pressure is arranged in the pot, can guarantee that pot inner pressure is in safe range by the gap pressure release of valve seat and valve rod.When pot body and pot cover fasten when putting in place, only opening part cooperates the compression spring to make and only open the lifting position that tongue piece is abdicated valve rod with lower handle, valve rod can freely rise, as pressure is arranged in the pot, promoting valve rod rises in the hole of upper handle setting, stoped the reciprocating motion of only opening tongue piece, only open part and lower handle card jail, pot cover is not opened, guaranteed the security performance of uncapping, had only in pot inner pressure drops to the safe pressure scope, valve rod since the gravity effect fall, only opening tongue piece has reciprocating space, could the smooth opening pot cover.This stopping valve function of use is single, can not play the safeguard protection effect of release when the pressure cooker pot inner pressure is excessive, needs to be used the safeguard protection requirement that just can reach pressure cooker with safety valve.
Safety valve mainly plays the safeguard protection effect of release when the pressure cooker pot inner pressure is excessive, is made up of valve rod, nut, valve seat, spring, sealing ring, and valve rod and valve seat top are provided with pressure release passage, are provided with spring in valve rod and the valve seat.When pot inner pressure in the safe pressure scope, valve rod and valve seat are under the effect of spring, pressure release passage is sealed; When pot inner pressure during greater than safety value, spring is compressed, and moves on the relative valve seat of valve rod, and pressure release passage is connected, and carries out pressure release, guarantees the safe in utilization of pressure cooker.Safety valve only just moves under the pot inner high voltage at present, can't artificially control.
Stopping valve and safety valve are set on the pot cover simultaneously, and the many and structure of perforate repeats to be provided with.Patent ZL98214955.7 discloses a kind of pressure cooker open and close cover safeties, it comprises safety valve of being made up of rubber base and seal bar and the self-locking mechanism of being made up of guard plate and spring, guard plate top hides on the seal bar top and has self-locking hole, the bottom is provided with guide rod, and lower end of the guide rod embeds lower handle and is in the guide groove of " V " font.The function of this utility model is to guarantee can't open when steam has not been arranged in disappointing step-down when pot cover does not close up and the pot function of pot cover, does not have the safety assurance function when pot inner pressure transships.
Patent ZL01222175.9 discloses a kind of pressure cooker safety locking motion, comprise pressure limiting valve, safety valve, stopping valve, combination push piece, upper handle is provided with and can holds the perforate that stopping valve moves, and safety valve is located in the stopping valve, and safety valve integral body becomes the spool of stopping valve.Because safety valve is located in the stopping valve, stopping valve weight is bigger, is difficult to satisfy simultaneously the quantification requirement of folding lid safe pressure in GB15066-94 or the GB13623-92 pressure cooker national standard.
Summary of the invention
The utility model provides a kind of pressure cooker with button only to drive safety device, has both had the function of stopping valve, has the function of safety valve again, simultaneously by losing heart step-down and uncap the security performance of assurance pressure cooker in the button control pot.
A kind of pressure cooker with button is only driven safety device, comprise the safety valve that is contained on the pot cover and place the interior PBU pushbutton unit of upper handle, described safety valve is made up of valve seat, valve rod, screw, spring, valve rod cooperates with the valve seat lower seal, described valve rod middle part is provided with boss, described PBU pushbutton unit by the block of band guide rod, only open part, venting part, spring are formed, cooperate with guide rod on only opening part, the lower end can cooperate with the lower handle upper rail; The venting part is provided with spring with only opening between part, the front end of the part of exitting is provided with the contact that can stretch into the perforate of pot cover edge; Be provided with lever between described PBU pushbutton unit and safety valve, the fulcrum of lever is positioned on the pot cover, and an end is fixing with block, and the other end passes the boss below that valve seat is against the valve rod middle part.
Described guide rod with only open part and cooperate by the inclined-plane.
Described lever passes the elastomer block that is located at upper handle inside.
The utility model device fastens when not in place at a pot cover and a pot body, the venting part is subjected to the pressure of spring, its front end contact stretches into the perforate of pot cover edge, back down the sealing ring between pot cover and pot body, make pot cover and the blow-by of pot body, as pressure is arranged in the pot, can guarantee that pot inner pressure is in safe range by the gap pressure release of backing down.When pot cover fastens with the pot body, the venting part cooperates with lower handle, live outer motion, when fastening puts in place, the contact of venting part just withdraws from from the perforate of pot cover edge, and only open part and import by the guide groove on the lower handle, and owing to the pressure of spring snaps in the guide groove, pot cover can't be opened, and has guaranteed the security performance of uncapping.
When pot inner pressure transshipped, the safety valve inner spring was compressed, and moved on the relative valve seat of valve rod, and pressure release passage is connected, and carries out pressure release, guaranteed the safe in utilization of pressure cooker.
When uncapping, must press button, drive lever action, lift the valve rod of safety valve, make it exhaust, force the part of only opening that is stuck in the guide groove is released from lower handle by guide rod and the mating reaction of only opening part simultaneously, the venting part stretches in the pot cover, makes the sealing ring distortion, rapidly exhaust pressure relief.No pressure in the pot could the smooth opening pot cover.Button can reset by the effect of spring pressure and elastomer block,
The utility model is provided with PBU pushbutton unit, and links with safety valve, has fully guaranteed the safe in utilization of pressure cooker.When uncapping, must pass through button actions, and make the step-down of fully losing heart in the pot, prevent risky operation effectively, significantly reduce the generation of security incident.
