The specific embodiment:
Embodiment 1:
Structural representation of the present utility model such as Fig. 1,2,3, shown in 4, include the float-controlled valve 100 that is installed on the set valve seat 1 of pot lid, pot lid of realizing that is installed on pot body is opened, the folding lid mechanism 200 that closes, wherein the spool 3 of float-controlled valve 100 can be at the height of valve seat 1, slide between the low level, folding lid mechanism 200 comprises the button 7 of uncapping that is applied in the power of uncapping, the lid that closes that fastens with the realization of pot body under the driving of the button 7 of uncapping detains 9, wherein pot covers and also is equiped with the push rod 6 that can slide thereon, one end of push rod 6 is provided with the rotation of folding lid mechanism 200 displacement done of action of uncapping is converted to the guiding piece 62 of the horizontal displacement of push rod 6, can not be when another positive stop end 61 of push rod 6 is placed at spool 3 and is in valve seat 1 low level by spool 3 its slide displacement amounts of control, pot cover can be opened, when spool 3 is in valve seat 1 high position, be subjected to spool 3 its slide displacement amounts of control, make on the position that pot cover can not open.
In the present embodiment, the above-mentioned button 7 of uncapping that applies the power of uncapping is contained in pot by jointed shaft BB hinge and covers, install and being contained in pot by jointed shaft CC hinge and covering with the lid button 9 that closes that pot body realize to fasten, the button 7 of uncapping includes drive end 71 and free end 72, the power of uncapping that its drive end 71 is applied by the user is rotated, and control the action of closing lid button 9 and realize and the fastening of the body of stewing that the free end 72 of the button 7 of uncapping is installed on the guide recess 62A of push rod 6 set guiding pieces 62.Uncap when uncapping under the normal condition end horizontal displacement L1 of free end 72 of button 7 of the positive stop end 61 of above-mentioned push rod 6 and the distance L 2 of spool 3 outer walls.
Freely suitable freely for guaranteeing moving of push rod 6, above-mentioned push rod 6 is installed in the set slideway 8 of pot lid.For push rod 6 can be automatically reset, above-mentioned push rod 6 is provided with automatic-reset spring 5.
For guaranteeing sealing, the positive stop end 61 of above-mentioned push rod 6 is set with seal 4, and the positive stop end 61 of push rod 6 covers in being sealedly connected on by seal 4.
Operation principle of the present utility model is as follows: shown in Fig. 2～3, under the normal condition, pushing the button 7 of uncapping drives and closes 9 rotations of lid button when pot lid is opened, the end horizontal displacement of free end 72 is L1, the end vertical displacement of drive end 71 is S1, and the end horizontal displacement of free end 72 when uncapping under the normal condition of the distance L 2 of the positive stop end of above-mentioned push rod 6 61 and spool 3 outer walls is L1.When the inner no pressure of electric cooker, spool 3 falls to the low level of valve seat 1 by deadweight, at this moment, push the button 7 of uncapping, uncap button 7 around jointed shaft BB rotation, and its drive end 71 drives downwards and closes lid button 9 around jointed shaft CC rotation, and free end 72 promotes push rod 6 and is moved to the left.Because the positive stop end 61 of push rod 6 is not subjected to any stopping, its level displacement left in theory can be unrestricted, and the end horizontal displacement of the button free end 72 of uncapping so just can the uncrossed L1 of reaching, and pot is covered open.
When there was pressure electric cooker inside, spool 3 was stressed and uses a high position that slides to valve seat 1, at this moment, push the button 7 of uncapping, uncap button 7 around jointed shaft BB rotation, and its drive end 71 drives downwards and closes lid button 9 around jointed shaft CC rotation, and free end 72 promotes push rod 6 and is moved to the left.When the horizontal displacement of push rod 6 reaches L2 (during L2＜L1), the positive stop end 61 of push rod 6 touches the outer wall of float spool 3 and stops to move, and drive the button drive end 71 of uncapping simultaneously and no longer continues to drive downwards and close lid button 9 and move, at this moment, the end vertical displacement S2 of drive end 71 must be less than S1, be not enough to drive and close lid button 9 and produce enough angles pot lid is opened, as shown in Figure 4.
Embodiment 2:
Structural representation of the present utility model such as Fig. 5,6, shown in 7, the present embodiment difference from Example 1 is that the above-mentioned button 7 of uncapping that applies the power of uncapping is contained on pot body by jointed shaft BB ' hinge, install to be contained in to stew and cover with the lid button 9 that closes that pot body realize to fasten by jointed shaft CC ' hinge, closing lid button 9 comprises that the button 7 of being uncapped drives to make and closes the leg 91 of lid button 9 integral body around jointed shaft CC ' rotation, realize clasp 92 with pot body fastening, follow and close lid button 9 integrally rotated free ends 93, the free end 93 that closes lid button 9 be installed on the guiding wall 62 of push rod 6 set guiding pieces 62 ' on, guiding piece wall 62 ' be used for closing the swing offset that covers button free end 93 to be converted to horizontal displacement, thus drive push rod 6 left, move right.
Shown in Fig. 6,7, under the normal condition, pushing the button 7 of uncapping drives and closes 9 rotations of lid button when pot lid is opened, the end horizontal displacement of free end 93 is L1, and the positive stop end 61 that makes above-mentioned push rod 6 in the present embodiment design and the distance L 2 of spool 3 outer walls are closed the end horizontal displacement L1 of the free end 93 of lid button 9 when uncapping under the normal condition.Other structures and the operation principle of present embodiment are substantially the same manner as Example 1, no longer describe in detail.
