Problems solved by technology
[0003] This structure has at least the following defects: (1) Install washers and split retaining rings sequentially on the three steel columns, the installation process is cumbersome, and the production efficiency is low; (2) Three steel columns are welded on the formed steel cover, and the processing process is troublesome , and it is prone to welding quality problems. Once the welding quality is not good, it will easily lead to the scrapping of the entire steel cover, so the production cost is high

Embodiment Construction
[0039] In the context of the present invention, orientation words such as "up" and "down" are used. It should be noted that these orientation words express the relative positional relationship of the lid when it is in the closed state during normal use, and Normal use means that the pressure cooker is placed on a level surface with the opening facing upwards. In addition, the term "axial outer side" is also used in the present invention. For the lid, its axial direction is equal to the axial direction of the pot, because in the case of the two lids, the axes of the two are considered to be the same, while the outer and The inside refers to the side that is relatively far away and closer to the pot, respectively. Accordingly, the "up and down direction" is equivalent to the axial direction of the pot or pot lid.
[0040] Aiming at the problems existing in the assembly and production of the medium-voltage pressure cooker lid in the prior art, the present invention provides a co...

The invention discloses a pot cover, which comprises an inner cover, a steel cover and a stopper. In an assembled state, the inner cover is located at the axial outer side of the steel cover, and the inner cover has an opening, and the inner cover is provided with an opening. The stopper is installed on the steel cover through the opening, and is relatively fixed with the steel cover, a receiving space is formed between a part of the stopper and the steel cover to accommodate a part of the inner cover and, during the rotation of the steel cover relative to the inner cover, a part of the inner cover is always located in the accommodating space. In the pot cover of the present invention, the stopper can effectively prevent the inner cover and the steel cover from being separated from each other in the axial direction, so as to realize the relative fixation of the two in the axial direction without hindering the relative rotation between the two. Compared with the prior art, the assembly process can be significantly simplified and the assembly efficiency can be improved. The invention also discloses an electric pressure cooker.
Description
technical field [0001] The invention relates to the technical field of kitchen appliances, in particular to a pot cover and an electric pressure cooker having the same. Background technique [0002] At present, in the assembling process of electric pressure cooker lids, three steel columns are mostly welded on the steel lid by welding, and then the steel columns are inserted into the chute corresponding to the plastic inner cover, and the steel column and the chute are sliding relative to each other to realize the steel column. The rotation of the cover relative to the inner cover, and then put gaskets on these steel columns, and insert the opening retaining ring into the groove at the top of the steel column to block the gasket below, so as to realize the vertical direction between the steel cover and the inner cover. relatively fixed. [0003] This structure has at least the following defects: (1) The gasket and the split ring are sequentially installed on the three steel...
