Pressure adjusting structure and pressure cooker having same

Abstract

The invention provides a pressure adjusting structure comprising a valve seat, an exhaust tube and a magnetic valve body. The lower end of the exhausting tube passes through the valve seat; the magnetic valve body sleeves the upper end port of the exhausting tube; a magnetic cushion block is arranged between the valve seat and the magnetic valve body; and the magnetic cushion block is provided with a magnetic cushion block adjusting structure adjusting movements of the magnetic cushion block in a horizontal direction. When a pressure limiting value of a pressure-limiting valve has to be adjusted, positions of the magnetic cushion block in the horizontal direction is adjusted by the magnetic cushion block adjusting structure, so an area of the magnetic cushion block relative to the magnetic valve body can be changed; when the area changes, the magnetic field force between the magnetic cushion block and the magnetic valve block can be changed; the pressure limiting value of the pressure limiting valve can be adjusted and food cooking effect of the pressure cooker can be improved; the pressure adjusting structure does not contain elastic members, so adjusting performance decrease due to elasticity extenuation of the elastic components under the high-temperature and high-humidity environment for long time can be avoided; and product reliability can be improved and service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of pressure cookers, in particular to a pressure regulating structure and a pressure cooker with the same. Background technique [0002] Pressure cooker has developed rapidly in the past ten years because of its strong cooking automation performance, short cooking time, and remarkable energy-saving effect of non-boiling cooking; high cooking temperature, single cooking temperature, automatic cooking control, no boiling in cooking, and no spillage of cooking fluid food Waiting is the characteristic of pressure cooker. In order to maintain these characteristics of the pressure cooker, for ten years, the pressure limiting valve used as a quick opening of the pressure cooker to exhaust and relieve pressure and an important safety guarantee is a gravity pressure limiting valve with a single pressure limit value, a spring pressure limiting valve or a magnetic pressure limiting valve. However, different foods requ...
