5, turning cylinder fork 009, turning cylinder 010, center of rotation 011 is from bottom to top put in the first axis hole 0072 of cover panel 007 successively, button spring 012, button spring guide pillar 013 is put in the second axis hole 0074 of cover panel 007 successively, safe valve rod 040, safe spool 042 is put in the valve opening 0075 of cover panel 007 successively, then cover panel 007 entirety that part is housed is buckled on pressure cover 023, allow the central shaft 0073 of cover panel 007 successively through compressing tablet 016 while buckling, central gear 017, pad 018, the center hole of support 019, then center nut 024 to be tightened on cover panel 007 central shaft 0073 in the below of pressure cover 023 is fixed whole cover panel 007, then the protruding edge 0411 of emergency valve seat 041 being pierced into locating hole 0234 by the below of pressure cover 023 is enclosed within safe spool 042, again safety valve silica gel ring 043 extruding is sticked into the card-tight part 0421 of safe spool 042, safety valve has been assembled.Then pot mouth sealing ring 025 is contained in the interior grooves place of pressure cover 023.So far, whole pressure cooker cover has been assembled.

G, handle are assembled:

Handle seat 0264 (two panels) is welded in respectively the appropriate location of pressure cooker body 027, handle fixed card 0262 is injected in the fixing hole 02611 of handle handle 0261, then handle guard ring 0263 is enclosed within the handle end 02612 of handle handle 0261, then the entirety of assembling is injected the Access Division 02641 of handle seat 0264, handle stator card 0262 is allowed to be stuck in fastener 02642 position of Access Division 02641, handle can be fixed on pressure cooker body 027, so far the assembling of a handle is completed, same method assembling another handle.

Button folding lid operation principle:

Press single button 002, under longitudinally acting on turning cylinder fork 009 in draw-in groove hole 00722, helical teeth 0092 in turning cylinder fork 009 inclined-plane 0102 promoted on turning cylinder 010 makes turning cylinder 010 turn to draw-in groove A00723, rocking bar 015 jack-up turning cylinder 010 and single button 002 is made under the action of the spring after unclamping single button 002, left pressure rings 021 and right left pressure rings 021 ' are opened automatically, and pressure cover 023 is opened; Again press single button 002, under longitudinally acting on turning cylinder fork 009 in draw-in groove hole 0072, helical teeth 0092 in turning cylinder fork 009 inclined-plane 0102 promoted on turning cylinder 010 makes turning cylinder 010 turn to draw-in groove B00724, tongue 0103 because of turning cylinder 010 is greater than the draw-in groove level face 00725 in 077 draw-in groove 2, the inclined-plane 0102 making it withstand turning cylinder 010 makes turning cylinder 010 not rise, left pressure rings 021 and right pressure rings 021 ' can not be opened automatically, for pressure cover 023 closes.

Air valve operation principle:

After closing lid, safe spool 042 when pressure is greater than 4kpa in covering in safety valve rises automatically and the chute 0202 passed on slide block promotes safe valve rod 040 rises from cover panel 007 and express in pot and have pressure, play warning function, effect is to make slide block can not transverse shifting and pressure rings can not be driven to open, and plays in pot the effect that when having air pressure, pressure cover 023 can not be opened, when pot internal gas pressure continues to rise, visual bonnet 028 can rise to certain height automatically to show inner pot pressure size, (note: predetermined pressure range is: comprise low-grade pressure label layer 0281 and high-grade pressure label layer 0282, the pressure of keeping out pressure label layer 0281 is between 40 to 60kpa, and the pressure of high-grade pressure label layer 0282 is between 90 to 110kpa, when pressure can continue to rise more than spool 037 visual during more than 90kpa, itself and steam vent 0311 is made to occur gap, the air pressure had more is discharged from steam vent 0311, now pot internal gas pressure can be discharged from the steam vent 0311 regulating valve seat 031 and make regulating valve bonnet 029 increase, gas can be discharged outside pot from the venthole 0291 regulating valve bonnet 029, because visual control valve overcoat 030 has certain space to cool and cushioning effect, the gas of discharging through regulating valve bonnet venthole 0291 can not with too many moisture content, thus there will not be phenomenon of spraying water as other pressure cooker, and make pot inner pressure pressure within 90 to 110kpa guarantee that pressure cooker normally works, when visual valve runs into blocking, when pot inner pressure reaches more than 140kpa, safety valve steel ball 033 automatically rises be vented and send sound and warns pot inner air pressure superelevation, and bulletin user closes thermal source, when safety valve and then lost efficacy, when pot inner pressure rises to 220 to 280kpa safety valve single piece can automatically and safety valve silica gel sheath 038 depart from, make pot inner pressure in 60 seconds, drop to below 20kpa and in manual non-restoring situation downforce pressure can not again rise.

Above-listed detailed description is illustrating for the utility model possible embodiments, and this embodiment is also not used to limit the scope of the claims of the present utility model, does not allly depart from the equivalence that the utility model does and implements or change, and all should be contained in the scope of the claims of this case.
