Pressure cooker

Abstract

A pressure cooker comprises a surface cover and an upper cover which are assembled into a cooker cover, an assembly gap between the surface cover and the upper cover forms an installation space, the upper cover is provided with an exhaust port, a float valve matched with the pressure cooker is arranged in the exhaust port, a float valve pressure limiting rod and a guide check block triggering thefloat valve pressure limiting rod to move are arranged in the installation space, the guide check block and the float valve pressure limiting rod are movably arranged in the installation space, one end of the float valve pressure limiting rod is located on one side of the exhaust port, the surface cover or the upper cover is provided with a key, and the key is connected with the guide check blockin a matched mode. The key is pressed to drive the guide stop block to move upwards, the guide stop block drives the float valve pressure limiting rod to move towards the exhaust port, and the float valve pressure limiting rod partially shields the exhaust port so as to limit the float valve from floating towards the exhaust port; the pressure in the pressure cooker is large, the float valve floats upwards towards the exhaust port, the float valve pressure limiting rod is prevented from moving towards the exhaust port, the key cannot be pressed, the problem that the cover cannot be opened at will when air pressure exists in the cooker is solved, and the pressure cooker has the advantages of being safe and reliable.

Description

technical field

[0001] The invention relates to a cooking appliance, in particular to a pressure cooker. Background technique

[0002] Before the electric pressure cooker is pressed, the gas in the pot needs to be discharged first, and the gas in the pot is mainly discharged through the float valve. At present, there is an exhaust channel in the float valve used in the electric pressure cooker, and a silicone sealing ring is installed at the bottom of the float valve. When the pressure in the pot is less than 4KPa, the pressure is not enough to lift the float valve. At this time, the gas in the pot is discharged through the float valve. When the pressure in the pot is greater than 4KPa, the pressure in the pot overcomes the gravity of the float valve and lifts the float valve to realize sealing. The lid cannot be opened in pressure mode.

[0003] Foods cooked under high pressure are loved by people for their unique taste. Now there are many types of pressure cookers on t...
