Pot lid exhaust structure

Abstract

The invention discloses a pot lid exhaust structure which comprises a pot lid, a pressure limiting valve component, a cover board and an exhaust button, wherein the cover board is connected in a detachable mode with the pot lid and a covering space is formed; the pressure limiting valve component is positioned in the covering space and is in sliding connection with the pot lid; the pressure limiting valve component is provided with a gas outlet; the exhaust button is in sliding connection with the cover board; the exhaust button is matched with the pressure limiting valve component and drivesthe pressure limiting valve component to slide to form an automatic exhaust position and a manual exhaust position; at the automatic exhaust position, the gas outlet of the pressure limiting valve component is positioned above the pot lid; and at the manual exhaust position, the gas outlet of the pressure limiting valve component communicates the upper surface of the pot lid with the lower surfaceof the pot lid. The pot lid exhaust structure implements conversion of the automatic exhaust position and the manual exhaust position, and can enable a user to control a size of a gas pressure in a pot body by the exhaust button so as to select whether to manually exhaust as required; and the pot lid exhaust structure is more humanized when in use.

Description

technical field [0001] The invention relates to a pot cover, in particular to a pot cover exhaust structure. Background technique [0002] At present, the pressure limiting valve of pressure cooker on the market generally adopts a heavy hammer type safety valve. This pressure limiting valve is set on the lid of the pot and is directly exposed to people's sight. When the pressure in the pot reaches the limit value, the safety valve will be forced to jack up. Release high-temperature steam outwards to reduce the pressure inside the pot. And when the user wants to actively reduce the pressure in the pot, the safety valve must be manually lifted or removed, and the high-temperature steam released by the current safety valve, whether it is passively reducing the pressure or when people actively reduce the pressure, has It may directly contact with the human body and burn the skin, the safety factor is low, and when the safety valve discharges high-temperature steam, the soup in ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages existing in the prior art that the pressure limiting valve is exposed, and the released high-temperature steam is likely to burn the user; when in use, the soup will be sprayed out with the steam, and the cleaning workload is large, etc., and provides a pot cover drainer. air structure
