Through placing hasp 8 in the holding cavity, make things convenient for the installation of hasp 8, directly insert hasp 8 to the holding cavity in, need not too much assembly structure and can realize the fixed of hasp 8, the assembly is simple, and the assembly precision is high, need not to consider fit clearance and assembly tolerance just can realize the fixed of hasp 8.
Specifically, the uncovering structure comprises a handle seat 7 and an uncovering crank 6, wherein the handle seat 7 and the uncovering crank 6 are rotatably connected. Of course, it can be understood that the handle base 7 and the cover opening crank 6 can be connected in various ways, as a preferred embodiment, the handle base 7 and the cover opening crank 6 are connected through the torsion spring 9, and the torsion spring 9 can provide a return force for the handle base 7, so that the handle base 7 and the cover opening crank 6 rotate relatively, and thus, the processes of automatically opening and closing the cover are realized.
Further, the cover opening crank 6 is provided with a first body 61, the first body 61 is connected with a second body 62, the first body 61 is provided with a sliding groove 611, and the sliding groove 611 is clamped with the lock column of the steel cover structure 5, so that the sliding groove 611 drives the lock column to rotate in the sliding groove formed in the upper cover 1.
Further, the second body 62 is provided with a first clamping groove 621, the first clamping groove 621 is clamped with the bending part of the torsion spring 9, and the linear part of the torsion spring 9 protrudes out of the end face of the cover opening crank 6 and is abutted against the handle seat 7 so as to provide a return force for the handle seat 7. The second body 62 is further provided with a second engaging groove 622, and the handle holder 7 and the door-opening crank 6 are rotated relatively to each other to be retracted by the second engaging groove 622. The second body 62 is further provided with a first stop 623 and a second stop 624, and the first stop 623 and the second stop 624 are respectively matched with the handle holder 7 to realize the rotation limitation of the handle holder 7 and the cover opening crank 6.
Further, the handle holder 7 is provided with a first protrusion 71 and a second protrusion 73, the first protrusion 71 and the second protrusion 73 rotate in a space formed by the first stopper 623 and the second stopper 624, and the first protrusion 71 abuts against the second stopper 624 or the second protrusion 73 abuts against the first stopper.
Specifically, the U-shaped end of the torsion spring 9 is assembled in the first clamping groove 621 of the cover opening crank 6 to fix the torsion spring 9, the handle seat 7 is directly assembled on the cover opening crank 6, the second stop block 624 of the handle seat 7 is matched with the clamping groove of the cover opening crank 6, and the main function of the first convex block 71 of the crank and the second stop block 624 or the second convex block 73 and the first stop block 623 in the butt joint is to limit the rotation angle of the handle seat 7 and the cover opening crank 6 between 0 degree and 30 degrees.
Further, be provided with boss 72 on the handle seat 7, boss 72 cooperatees with exhaust structure, and when boss 72 and exhaust structure looks butt, handle seat 7 and uncap crank 6 rotate certain angle relatively, exhaust to the gas in the pot body, and after the exhaust, handle seat 7 overcomes the effort of torsional spring 3, and the rotation angle of uncap crank 6 and handle seat 7 is 30.
Further, a rotating shaft is arranged on the handle base 7, and the distance between the end of the handle 75 and the rotating center of the rotating shaft is smaller than or equal to the distance between the rotating center of the rotating shaft and the lock catch 8.
Further, a mounting groove 74 is arranged on the handle base 7, a magnet is arranged in the mounting groove 74, and the magnet is matched with a proximity switch arranged on the upper cover 1 to control the electric pressure cooker to open the cover by mistake.
Furthermore, the whole cover opening process is divided into a cover closing state, a rotating state, a cover opening state and a cover closing state, and the motion state of the cover body assembly relative to the pot body is described through the four states.
Closing the cover: due to friction, the steel cover structure 5 clamps the cover opening crank 6; due to the torque action of the torsion spring 9, the relative angle between the cover opening crank 6 and the handle seat 7 is 30 degrees;
the rotating state is as follows: after the user applies force, the handle seat 7 overcomes the acting force of the torsion spring 9, and the relative angle of the cover opening crank 6 and the handle seat 7 is reduced to 0 degree. When no pressure exists in the cooker, the handle seat 7 can drive the steel cover structure 5 to rotate;
uncovering state: when the steel cover structure 5 is rotated to the proper position, the steel tooth structure of the steel cover structure 5 is separated from the pot teeth of the pot body, and meanwhile, the handle 75 of the handle seat 7 is contacted with the lock catch 8 to jack the lock catch 8 to be separated from the pot body, so that the cover opening is realized;
a cover closing state: after the user closes the lid, because exert the power and disappear, handle seat 7 can't overcome the effort of torsional spring 9, and handle seat 7 begins to reset, and the handle is contactless with hasp 8, and hasp 8 and the body of a boiler re-contact realize closing the lid lock and die.
Further, in a specific using process, a user triggers a start button to perform a cooking process, in the cooking process, the user performs misoperation, rotates the handle seat 7, overcomes the acting force of the torsion spring 9 by the handle seat 7 after applying force, reduces the rotating angles of the handle seat 7 and the cover opening crank 6 to 0 degree, and presses the lever by the handle seat 7, so that the electric pressure cooker starts to exhaust. However, pressure exists in the cooker, the steel cover structure 5 cannot move, the handle seat 7 assembly cannot drive the steel cover structure 5 to rotate, and the upper cover 1 cannot be opened. And handle seat 7 drives magnet and proximity switch disconnection, and the controller receives the signal of telecommunication, through the wrong operation of voice prompt user carrying on. After the user releases his/her hand, the handle holder 7 is returned to 30 ° from the rotation angle of the lid opening crank 6 by the return force of the torsion spring 9 from the handle holder 7. The handle base 7 does not press the lever, so that the electric pressure cooker does not exhaust.
