Electric pressure cooker and safe uncovering mechanism thereof

Abstract

The invention discloses an electric pressure cooker and a safe uncovering mechanism thereof. The safe uncovering mechanism comprises a cooker cover (8), a fixed cover (1) and a floater (4) as well as a magnetic adsorption part (5) and an electromagnet (7), wherein the fixed cover (1) is arranged in the cooker cover (8), and the floater (4) is arranged on the fixed cover (1) in a floating manner; the magnetic adsorption part (5) is arranged at one end, away from the inside of the electric pressure cooker, of the floater (4); the electromagnet (7) is arranged corresponding to the magnetic adsorption part (5) and fixed on the cooker cover (8). According to the safe uncovering mechanism, uncovering protection is realized by controlling the electromagnet (7), uncovering protection is favorably realized, and uncovering by mistake is prevented; floater floating is facilitated by the magnetic aid, the requirement for the weight accuracy of the floater is lowered, production is facilitated, and the production efficiency is improved; at the initial pressure boosting stage, the floater floats upwards by magnetic force, sealing inside the cooker is guaranteed at the stage, and rapid pressure boosting is facilitated.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an electric pressure cooker and a safety opening mechanism thereof. Background technique [0002] When the electric pressure cooker is in use, the pressure in the inner pot is relatively high. In order to improve the safety of the electric pressure cooker, a safety cover opening mechanism is provided on the electric pressure cooker, so as to protect the cover opening operation of the electric pressure cooker. [0003] The safety release mechanism includes a float. When the pressure in the electric pressure cooker is small (less than a certain value), the float is in a falling state due to its own gravity. When in this state, the float is not in the position-limiting structure of the pot cover, and now the pot cover can be rotated to open. When the pressure in the electric pressure cooker is high (greater than or equal to a certain value), the float is affected by ...

AI Technical Summary

Problems solved by technology

[0004] However, in the initial stage of boosting pressure, due to the low pressure in the pot, the float cannot float up, and it is very easy to open the lid by mistake; Slower; the smaller the error between the gravity of the float and the buoyancy of the float when the pressure in the electric pressure cooker reaches a certain value, the more conducive to the accurate floating of the float. processing, affecting production efficiency
