Pressure cooker cover opening and closing structure

Abstract

The invention discloses a pressure cooker cover opening and closing structure comprising a supporting piece, a cover body and a cooker body, wherein the cover body covered on the cooker body, the pressure cooker cover opening and closing structure further comprises a first rotary connecting piece, a second rotary connecting piece, a push piece, a first transmission connecting piece, a transmission piece and a second transmission connecting piece, an opening position and a closing position are arranged between the cover body and the cooker body, and the push piece pushes the cover body to rotate between the opening position and the closing position through the first transmission connecting piece, the transmission piece and the second transmission connecting piece. According to the pressure cooker cover opening and closing structure, in a rotation process of the cover body, the supporting piece keeps unmovable, only the cover body rotates relatively to the cooker body, and the purpose of freely opening and closing the cover body is finally realized, the pressure cooker cover opening and closing structure is simple and novel, convenient to produce and is convenient and labor-saving to operate, the cover body can be opened and closed just by one hand, and the cover body can be accurately located in an opening and closing process, thereby better satisfying the demands in the daily life of people and facilitating market promotion.

Description

technical field [0001] The invention relates to the field of utensils for cooking food under pressure, in particular to an opening and closing structure of a pressure cooker lid. Background technique [0002] Pressure cooker, also called pressure cooker. The principle of a pressure cooker is very simple, because the boiling point of water is affected by the air pressure, the higher the air pressure, the higher the boiling point. When the air pressure was less than 1 atmospheric pressure, water would boil at less than 100°C, and when the air pressure was greater than 1 atmospheric pressure, water would boil at a temperature higher than 100°C. The commonly used pressure cooker is designed using this principle. Using a pressure cooker can not only shorten the cooking time, but also improve the taste of food after cooking and improve people's quality of life. [0003] Its pot cover of traditional pressure cooker usually adopts these two structures of screw-on type or clamp ty...
