Pressure-cooker cover

Abstract

The invention belongs to a pressure-cooker cover, and is implemented simultaneously or individually by three parts, the pressure-cooker cover, a seal ring and a support piece for fixing the seal ring, wherein the cooker cover is divided into two layers, the first layer is a cover top layer which is a circumferential wall formed by extending downward the periphery of the cover top of the cooker cover; a connecting plane is arranged at the connection between the cover top layer and a buckle teeth layer of the cooker cover; a circumferential wall formed by extending downward the periphery of the connection plane is a second buckle teeth layer; the buckle teeth layers are provided with buckle teeth for buckling the cooker body; the main body section of the seal ring is a 7-shaped ring body, one side of the ring body is designed to be a plane, and the other side is designed to be a cambered surface; the plane is adhered in the cooker cover and fixedly mounted by a plurality of T-shaped support pieces; and when the cover is closed, the cambered surface is adhered to a cooker mouth of the cooker body, which forms sealing between the cooker cover and the cooker body. The pressure-cooker cover provided by the invention has the advantages of using a small amount of material, and being firm and stable in the fixing mode, simple in structure, safe and reliable, low in manufacturing cost, low-carbon, environment-friendly and energy-saving.

Description

technical field [0001] The invention belongs to cooking pot accessories, in particular to a pot cover with a sealing ring firmly clamped, a sealing ring and a bracket for a pressure cooker lid, and belongs to the technical improvement of the sealing structure of the existing pressure cooker lid. Background technique [0002] For the survival and development of the enterprise, we will constantly develop new products. The development of new products is mainly reflected in two ways: one is to add new functions, such as realizing automation on the basis of piezoelectric cookers, or in other words, on the basis of electric rice cookers. To increase the function of the pressure cooker, that is, the electric pressure cooker involved in this application. The second is to improve competitiveness by reducing costs through technological reform, and this application falls into this category. [0003] Before using the existing pressure cooker or electric pressure cooker, the sealing rin...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned pot cover has been used until now and has not been changed, but it has the disadvantages of large volume and many materials.

At the same time, the fixing method of the sealing ring is not firm or stable, there are potential safety hazards, and it is difficult to remove and clean, resulting in problems such as dead ends in hygiene
