Cover opening and closing mechanism of cooker

Abstract

The invention provides a cover opening and closing mechanism of a cooker, which belongs to the technical field of cookers, and solves the problems of structure complexity and poor security of a self-locking mechanism of the existing common pressure cooker. The cover opening and closing mechanism of the cooker is arranged between a cooker cover and a cooker body and comprises clamping grooves which are symmetrically arranged on the two sides of the cooker body and two pinch plates which are symmetrically arranged on the inner side of the cooker cover; a spring is arranged between the two pinch plates, and the two pinch plates tend to be embedded in the corresponding clamping grooves under the elasticity action of the spring; and the inner side of the cooker cover is also connected with an opening stop piece, and the opening stop piece moves to the part between the two pinch plates when pressure in the cooker rises. The cover opening and closing mechanism of the cooker provided by the invention has the advantages of being simple in structure, convenient for opening and closing the cover, high in security and the like.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and relates to a cooking utensil, in particular to an opening and closing mechanism of a pressure cooker. Background technique [0002] The pressure cooker is also called a pressure cooker. It can be used to heat the cooked food to more than 100 ℃. It has a unique high temperature and high pressure function, which greatly shortens the cooking time and saves energy. Since it will generate high pressure during the cooking process, in order to prevent safety accidents from opening the lid when the pressure inside the pressure cooker is high, and to improve the safety performance of the pressure cooker, a self-locking mechanism that prevents the lid from opening when the pressure inside the pot is too high will be designed. . [0003] For example, a Chinese patent discloses a pressure cooker self-locking device [Application No.: 200920185421.0; Announcement No.: CN201414692Y], which include...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned pressure cooker self-locking device has a relatively complicated structure. When the upper handle and the lower handle are not aligned, the self-locking slider can slide freely in the upper handle, so it will occur that the pot lid and the pot body are not fully fastened. If the slider is not stuck on the slider stop pin, there is a high potential safety hazard. If the pressure in the pot increases at this time, it may even cause the pot cover to burst, causing harm to nearby people.

In addition, too much force when closing the lid will also cause the lid to be too tight and difficult to open
