The cooker main body is provided with a component having a snap tooth. This component may be an inner port or an outer port. The cooker lid is provided with a tooth snap and a transmission mechanism for opening and closing the lid. The essence of the present invention is that the transmission mechanism for opening and closing the lid is a labor-saving linkage mechanism. The lifting link mechanism drives the toothed snaps on the lid of the cooker to snap or unseat together with the snap tooth on the inner port or outer port to open and close the lid. The lifting link mechanism can greatly shorten the arm of the force for opening and closing the lid and then reduce the moment of force required to open and close the lid thereby achieving the object of easily opening and closing the lid . The lifting link mechanism can be driven and driven by a gear-engaging transmission mechanism, a crank-connecting rod linkage mechanism or a cam linkage mechanism, and then a toothed snap on the lid of the cooker To be snapped together with the inner port or the outer port on the cooker body or separated from the inner or outer port to achieve opening and closing of the lid.

Both the drive wheel and the driven wheel are mounted and secured on the inner cap. The handle and drive wheel for opening and closing the lid are fastened together or made as an integral part. The user turns the handle to drive the drive wheel to rotate, which in turn drives the driven wheel to rotate. The driven wheel is connected to the toothed snap at the other end and drives the toothed snap to rotate along the slide slot on the inner cap.

According to one embodiment, in the above-described electrothermal-pressurizing device having a mechanism for easy opening and closing of the lid according to the present invention, as a lifting link mechanism, the crank-connecting rod link mechanism is connected together by a hinge, A rotatable crank and a connecting rod. The toothed snaps are slidably connected to the slide slots on the inner lid and are rotatable along the slide slots on the inner lid. Both the crank and the connecting rod are fixed on the inner lid. The handle and crank for opening and closing the lid are fastened together or made as an integral part. The user turns the handle to drive the crank to rotate, which in turn drives the connecting rod to rotate. The connecting rod is connected to the toothed snap at the other end and drives the toothed snap to rotate along the slide slot on the inner cap.

According to one embodiment of the present invention, in the above-mentioned electrothermal-pressurizing apparatus having a mechanism for easy opening and closing of the lid, as a lifting link mechanism mechanism, a cam link mechanism mechanism includes a cam and an ejector pin ejector pin. The ejector pin is provided with a reset spring that allows the ejector pin to automatically return to its original position without external force. The toothed snap is slidably connected to the slide slot on the inner lid. Both the cam and ejector pins are secured on the inner cap. The handle and cam for opening and closing the lid are fastened together or made as an integral part. The user turns the knob to drive the cam to rotate, which then drives the ejector pin to rotate. The ejector pin is connected to the toothed snap at the other end and drives the toothed snap to rotate along the slide slot on the inner cap.

In comparison with the prior art, the transmission mechanism for opening and closing the lid of the electrothermal pressure device of the present invention is designed as a lifting link mechanism, which is driven by a gear engagement transmission mechanism, a crank-connecting rod link mechanism or a cam link mechanism And transmission. The lifting link mechanism mechanism overcomes such deficiencies that the conventional swing link for opening and closing the lid is too long, the resistance is excessively large when the lid is opened and closed by the handle, and a great effort needs to be made. The original arm of the force is shortened by lifting mechanical design, making opening the lid easier and less forceful. This makes the device more convenient for consumers to use.
