It is equipped with limit hole 311 by its extending direction on 310,100 eccentric position of spiral cover is equipped with driving lever 110, and liner 210 is led equipped with arc
To hole 211, driving lever 110 protrudes into limit hole 311 through arcuate guide hole 211, and gear member 400 drives driving member 300 to do directly
Line moves back and forth, and so that clicking section 310 is pushed driving lever 110, arcuately pilot hole 211 slides, and then drives spiral cover 100 by driving lever 110
Rotation, meanwhile, driving lever 110 can also slide in limit hole 311.
The spiral cover 100 according to the present embodiment, the distance of driving lever 110 to 100 axis of rotation of spiral cover is L2, if driving
Component driver spiral cover 100 rotates about axle center and moves in a circle, then the motion profile of driving lever 110 is with 100 rotary shaft of spiral cover
The heart is the circular trace in the center of circle, is revolved since the axis of rotation of gear member 400 and spiral cover 100 is greater than driving lever 110 to spiral cover 100 away from L1
The distance of the shaft heart is L2, and compared with prior art, the present embodiment has pulled open the axis of rotation of gear member 400 and spiral cover 100 away from rotation
100 rotary arm of lid increases, and under the conditions of same torque, spiral cover 100 is easier to be driven to rotate, conversely, driving assembly then can be with
Smaller drive force spiral cover 100 rotates, and especially in the case where manual folding lid, the operation of user is more laborsaving.
Referring to Fig.1, the driving assembly of the present embodiment further includes rotating handle 500, and rotating handle 500 is located at outside upper cover 200
Side and with gear member 400 is concentric is fixedly connected, rotate rotating handle 500 to drive gear member 400 to rotate.Based on the present embodiment
Scheme, due to rotating handle 500 with gear member 400 is concentric is fixedly connected, the axis of rotation of gear member 400 and spiral cover 100
It is also the axis of rotation of rotating handle 500 and spiral cover 100 away from L1 away from eliminating 500 position of rotating handle as a result, and made to pot cover
Rotating handle 500 can be set in pot cover peripheral position in the limitation of type, as shown in the present embodiment Fig. 1, rotating handle 500
The position on front side of pot cover, user's operation are more convenient.Compared to the prior art, the present embodiment is by rotating handle from spiral cover 100
Portion removes, so that can do other structures design other than rotating handle 500 in the middle part of spiral cover 100, such as the present embodiment is in spiral cover 100
Exhaust pipe 120 is arranged in center, and upper cover 200 is equipped with weight 800, and weight 800 buckles on exhaust pipe 120, this makes pressure cooking
Center exhaust may be implemented in the spiral cover 100 of utensil.
In other embodiments, in the case where not limiting gear member quantity, side that can be combined by multiple gear members 400
Formula transmits rotating handle torque, and rotating handle can have more positions to select on pot cover, meet diversified design requirement.
Referring to Fig.1, the upper cover 200 of the present embodiment is also equipped with microswitch, the master of microswitch and pressure cooking appliance
Circuit electrical connection is controlled, gear member 400 and driving member 300 can trigger the microswitch, judge in place for open/close lid.Specifically
Say: upper cover 200 is also equipped with the first microswitch 600 and the second microswitch 700, and the first microswitch 600 is located at transmission
On the sliding trace of part 300, the second microswitch 700 is located on the rotational trajectory of rotating handle 500, sets in rotating handle 500
There is the convex block for touching the second microswitch 700.When rotating rotating handle 500 and carrying out closing lid, driving member 300 is to the first fine motion
The sliding of 600 direction of switch, and spiral cover 100 is driven to rotate simultaneously, when driving member 300 touches the first microswitch 600, feedback master
Control circuit closing lid signal in place；When rotating backward rotating handle 500 and being uncapped, the convex block in rotating handle 500 is micro- to second
Dynamic switch 700 is drawn close, and when convex block touches the second microswitch 700, feedback governor circuit is uncapped signal in place, in this way design,
Pressure cooking appliance use is more safe and reliable.
Embodiment two
The present embodiment and embodiment one the difference is that: the pressure cooking appliance of the present embodiment uses electric folding
Lid, specific: driving assembly further includes motor, and motor-driven gear part rotates, it should here be understood that: motor can directly drive
Gear member rotation, or drive gear member to rotate again by retarder output.The scheme of this implementation improves the automation of product
Operation, the safety accident for avoiding user from causing by folding lid misoperation improve Product Safety；And the present embodiment is not
Need to design rotating handle on pot cover, cover structure becomes simpler, and pot cover is moulded more beautiful, original installation rotation
