Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, the utility model provides an electric pressure cooker, which comprises a cover body 1, a cooker body 2 screwed with the cover body 1, an inner container 21 arranged in the cooker body 2 and a cover locking device 3 for limiting the rotation of the cover body 1, wherein the cover locking device 3 is arranged on the cover body 1;
the cover locking device 3 comprises a cover opening lever 31, a cover opening key 32, a cover locking column 33 used for limiting the rotation of the cover body 1 and a linkage mechanism used for limiting the pressing of the cover opening key 32, the pot body 2 is provided with a groove 22 matched with the cover locking column 33, one end of the cover opening lever 31 is connected with the cover locking column 33, and the other end of the cover opening lever corresponds to the cover opening key 32;
the interlocking mechanism comprises a push rod connecting plate 34 positioned on one side of the cover opening key 32 and a float valve 35 used for limiting the movement of the push rod connecting plate 34, and the push rod connecting plate 34 is provided with a limiting hole 341 corresponding to the float valve 35;
by pressing the door opening button 32, the push rod link plate 34 is pushed open and one end of the door opening lever 31 is pressed down in order to lift the cover locking column 33 out of the groove 22.
The cover body 1 is provided with a cover body clamping edge 11, the inner container 21 is provided with an inner container clamping edge 23 corresponding to the clamping edge of the cover body 1, and the inner container clamping edge 23 is overlapped with the cover body clamping edge 11 to limit the separation of the cover body 1 and the inner container 21. The cover body 1 is also provided with a pressure release valve 4.
Specifically, the door opening button 32 includes a button body 321, a door opening plate 322 for depressing the door opening lever 31, and a return spring 323 for resetting the button, the button body 321 is provided with a spring post 324 for depressing the door opening plate 322, and the return spring 323 is sleeved on the spring post 324. Correspondingly, the surface of the cover body 1 is provided with an uncovering key slot for installing the uncovering key 32, and the uncovering key slot is provided with a through hole through which only the spring column 324 passes. The cover opening button 32 can be automatically reset when external force is lost.
Further, in order to facilitate the opening operation, the cover body 1 is provided with a magnetic plate 12 for keeping the opening key 32 in a pressed state, and the magnetic plate 12 is arranged corresponding to the opening cover plate 322; the open cover plate 322 is provided with a magnetic substance 325 for being adsorbed on the magnetic plate 12. It should be noted that, since the normal and complete pressing of the lid opening button 32 is a prerequisite for opening the lid body 1, as long as the position of the magnetic plate 12 is located at the maximum stroke of the lid opening plate 322, when the lid opening plate 322 is pressed onto the magnetic plate 12, the attraction between the magnetic substance 325 and the magnetic plate 12 can limit the resilience of the return spring 323, so as to keep the lid opening plate 322 in the completely pressed state, and the lid opening button 32 does not need to be pressed by a human hand all the time, thereby facilitating the subsequent lid opening rotation operation. Preferably, the magnetic material 325 is a magnet, and the magnetic plate 12 is an iron plate.
Referring to fig. 4, in order to separate the open cover plate 322 after being adsorbed to the magnetic plate 12 for repeated use, the cover body 1 is further provided with a reset lever 13 for assisting the reset of the open cover plate 322 and a reset key 14 for pressing down the reset lever 13, one end of the reset lever 13 corresponds to the reset key 14, and the other end corresponds to the open cover plate 322. Therefore, when the cover opening plate 322 is adsorbed on the magnetic plate 12 under the action of the magnetic substance, the return spring 323 cannot be normally reset, and the reset button 14 can be pressed to make the reset lever 13 forcibly lift the cover opening plate 322, so that the cover opening plate 322 is separated from the magnetic plate 12, and finally the return spring 323 can be normally rebounded. With this arrangement, the user must fully depress the lid opening button 32 to open the lid body 1. The lid release button 32 cannot be pressed in the presence of pressure in the pan and the position of the lid release plate 322 can be manually reset.
In order to facilitate the push-open movement of the push rod connecting plate 34, the cover-opening plate 322 and one end of the push rod connecting plate 34 are both provided with contact parts 5 for mutual pushing, and the contact parts 5 are provided with cambered surfaces for contact. Through the arrangement of the cambered surface, the force acting downwards on the cover opening plate 322 generates a lateral thrust on the push rod connecting plate 34.
Correspondingly, in order to guide the movement of the push rod connecting plate 34, a mounting seat 15 for guiding the push rod connecting plate 34 to translate is arranged in the cover body 1, and the float valve 3535 is arranged on the mounting seat 15; the mounting seat 15 is provided with a U-shaped surrounding edge 16 for limiting the translation range of the push rod connecting plate 34;
the push rod connecting plate 34 includes a limiting portion 342 adapted to the surrounding edge and extending portions 343 disposed on two sides of the limiting portion, the limiting hole 341 is disposed on the limiting portion 342, the U-shaped surrounding edge 16 is provided with a notch 17 corresponding to the opening cover plate 322 for the extending portion to pass through, that is, the width of the limiting portion 342 is greater than that of the extending portion 343. The limiting part moves in the U-shaped surrounding edge 16 along the opening direction of the notch 17.
Further, in order to restrict the rotation of the cover body 1 more securely, one end of the push rod connecting plate 34 is provided with an auxiliary lock cover column 6, the inner side of the cover body 1 is provided with a side hole 18 for the auxiliary lock cover column 6 to extend out, the side hole 18 corresponds to the liner clamping edge 23, and an auxiliary spring for ejecting the auxiliary lock cover column 6 out of the side hole 18 is arranged in the cover body 1. Therefore, when the push rod connecting plate 34 is not pushed by the opening cover plate 322, the auxiliary spring will maintain the state of the auxiliary lock cover column 6 extending out, and when the auxiliary lock cover column 6 extends out, the auxiliary spring will contact with the side wall of the liner clamping edge 23, thereby limiting the relative rotation between the cover body 1 and the liner. On the other hand, the auxiliary spring can also assist in the return of the push rod web 34.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the utility model.
