The using method of the present invention：
After low pressure lid assembles, with pinching the hand grip portion of protecgulum pearl tooth bar and holding of bonnet pearl tooth bar before and after handss
Portion, firmly holds inward, now, the tooth-strip part rearward movement of protecgulum pearl tooth bar, the tooth-strip part of bonnet pearl tooth bar travels forward, due to
The tooth-strip part of protecgulum pearl tooth bar is engaged with the upper right of lid pearl gear 3, and the tooth-strip part of bonnet pearl tooth bar is upper with lid pearl gear 3
Engage on the left of portion, so that lid pearl gear 3 carries out rotate counterclockwise, the rotating counterclockwise such that and lid pearl tooth of lid pearl gear 3
Take turns the left locking rack of 3 bottom engagements and right locking rack moves left and right, due to tooth-strip part and the lid pearl gear 3 of left locking rack
Lower rearward side engagement, the tooth-strip part of right locking rack is engaged with the lower front side of lid pearl gear 3, so that left locking rack
It is moved to the left, right locking rack moves right, then low pressure lid is covered in pot 16, with the silica gel sealing ring on too low gland
Handss are now unclamped by 12 contacts with pot 16 edge, in the presence of back-moving spring 6, the hook portion of left locking rack and right lock
The hook portion of tight tooth bar is hooked on the left and right sides at pot edge, respectively thus pot 16 is sealed；
When pot is after heating, internal temperature and air pressure raise, and the air pressure within when pot reaches certain critical point
Afterwards, air is flowed at the air outlet valve fixture 19 of valve module of giving vent to anger by the venthole of weight valve 23 of giving vent to anger, by inside
Air outlet valve copper piece 18 is above pushed away by pressure, and air spills and final aperture stream from bonnet 20 of giving vent to anger from air outlet valve copper piece 18 gusset
Walk, thus ensureing to cause because pressure is excessive danger inside pot；
When give vent to anger valve module because pot in food by weight valve 23 of giving vent to anger give vent to anger hole plug when, pot interior air-flow through peace
The venthole of the safe weight valve 14 of full valve assembly, enters in the hollow emergency valve seat of relief valve assembly, by relief valve steel ball 8
Push away, air flows out from relief valve steel ball 8 gusset；
When you will open low pressure lid, firmly hold the hand grip portion of protecgulum pearl tooth bar and holding of bonnet pearl tooth bar with handss
Portion, firmly holds inward, now, stretchs out, due to right locking teeth about left locking rack and the foregoing principle of right locking rack
Its interior relief valve steel ball 8 is driven and moves right by steel ball folder hole on bar together, and air will quickly flow out, finally from safety
The indentation, there of bonnet 24 flows out, thus being easily removed low pressure lid.This design can be opened at any time and cover back when be can achieve cooking food
One facility of pot cover, thus solve pressure cooker giving vent to anger slowly, opens the inconvenient situation of pot cover halfway.
