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 connected with the valve seat via a magnetic cushion block adjusting structure adjusting up-down positions of the magnetic cushion block. When a pressure limiting value of a pressure-limiting valve has to be adjusted, the up-down positions of the magnetic cushion block is adjusted by the magnetic cushion block adjusting structure, so a distance from the magnetic gasket to the magnetic valve body can be changed; when the distance changes, magnetic field force between the magnetic cushion block and the magnetic valve body can be changed; the pressure limiting value of the pressure limiting valve is the self weight of the magnetic valve body and the magnetic field force between the pressure limiting valve and the magnetic valve body; the pressure limiting value of the pressure limiting valve can be adjusted and food cooking effect of the pressure cooker can be improved; meanwhile, the use of elastic components such as springs can be avoided in the adjusting structure, so fewer components are required; and the pressure adjusting structure is simply structured, convenient to assembly and has high reliability.

Cooking utensil
Disclosed is a cooking utensil. The cooking utensil comprises a pot body, a pot lid, a pressure limiting valve, a transmission piece and a driving device; the pot body is used for containing food to be cooked; the pot lid covers the pot body and is provided with an exhaust passage; the pressure limiting valve is arranged on the exhaust passage; the transmission piece is arranged on the pot lid; the driving device is arranged on the pot lid and deviates a certain distance from the pressure limiting valve so that the transmission piece can be pushed to horizontally jack and push the pressure limiting valve to be switched on. By means of the technical scheme, the problem is effectively solved that in the prior art, opening and closing of pot lids are unsmooth due to air trapping of electric pressure cookers.
