Lid and pressure cooking device

Abstract

The invention provides a cover and a pressure cooking device. The cover comprises a pot cover, an inner cover, a surface cover and an electromagnetic exhaust valve, wherein the electromagnetic exhaustvalve comprises a valve seat, a valve core and a valve cover, the surface cover is provided with a mounting cavity, the top and bottom of the mounting cavity are respectively provided with openings,the valve seat is installed in the mounting cavity, the valve core is fixedly installed in a valve seat mounting hole, the upper end of the valve core presses against the upper end surface of the valve seat, the top end of the valve core is cooperatively connected with the valve cover, and the valve cover moves relative to the valve core to open or close the electromagnetic exhaust valve; and thebottom end of the valve core penetrates through the bottom opening of the mounting cavity and is fixedly connected to the pot cover, limiting ribs protruding toward the inner side are arranged on theside wall of the mounting cavity, the bottom end of the valve seat presses against the upper end surfaces of the limiting ribs, and the lower end surfaces of the limiting ribs press against the pot cover or the inner cover. The cook and the pressure cooking device, adopting the scheme, eliminate a portion of the surface cover between the valve seat and the valve cover, thereby eliminating the problem that the contact position of the surface cover and the valve core is easily deformed, and preventing the electromagnetic exhaust valve from leaking air.

Description

technical field [0001] The present invention relates to the field of cooking devices, and more specifically, to a cover body and a pressure cooking device having the above-mentioned cover body. Background technique [0002] The current pressure cooking device uses an electromagnetic exhaust valve to realize automatic exhaust. The product changes the current magnitude and / or direction of the coil in the electromagnetic valve seat through circuit control, so that the magnitude or direction of the magnetic field generated by the electromagnetic valve seat changes. Attract and repel the electromagnetic valve, thereby controlling the opening and closing of the electromagnetic exhaust valve. [0003] In order to ensure that the gap between the surface cover and the pot cover does not exceed the standard, the structural scheme adopted by this type of product is: set an inner cover between the pot cover and the surface cover, fix the electromagnetic valve seat on the inner cover, an...

Problems solved by technology

[0004] In this solution, the surface cover is stretched by the exhaust valve core for a long time, and because the contact area between the exhaust valve core and the surface cover is small, after the product works for a long time, the surface on which the exhaust valve core is assembled will be deformed, resulting in The periphery of the contact surface between the surface cover and the exhaust valve core is raised, and the raised position is easy to lift the electromagnetic valve cover, causing the electromagnetic exhaust valve to leak, resulting in the product not working properly

It can be seen that the existing product structure scheme still has a lot of room for improvement
