The present disclosure provides a float valve motion detection device, a pot cover assembly and a pressure cooking appliance, the float valve motion detection device comprising: a float valve, a hollow inductance coil and a detection circuit. A valve core of the float valve is made of materials having permeability unequal to that of air. When the valve core is pushed by the pressure in a pot from a first position to a second position, the volume of the valve core in the hollow inductance coil changes, which changes the inductance of the hollow inductance coil. A detection circuit determines the position of the valve core by means of detecting the change in the inductance of the hollow inductance coil so as to determine whether it is safe to uncover at the current time.

A muffler cover for an appliance includes a first room, second room, and a first channel. The second room is positioned separate from the first room. The first channel is connected to the first room via a first inlet and connected to the second room via a first outlet. The first channel changes from a first direction to a second direction and changes from the second direction to a third direction. The first direction is substantially opposite to the second direction, and the second direction is substantially opposite to the third direction. A muffler and an appliance using the muffler are also provided.

A steam regulation valve, includes: a first portion, a second portion, and a flow path defined by the first portion and the second portion. The second portion is movable relative to the first portion to decrease a cross-sectional area of the flow path in response to an increase in pressure applied to the second portion.

An electric pressure cooker comprises a body having outer pot and inner pot received therein and a lid covering the cooker body. The outer pot and the lid comprise matching teeth for lockingly engagement upon rotating the lid into closure. The cooker body comprises a pair of cooker handles extending outwardly from a sidewall thereof. The cooker handle comprises handgrip portion. The inner pot comprises inner pot body and a pair of inner pot handles connected thereto. The handgrip portion extends to align with or beyond the inner pot handle, so that a user holding the cooker handles will avoid gripping the inner pot handles. A vertical gap between the inner pot handle and the handgrip portion allows hand access. When the user is reaching for the inner pot handle the fingers will contact the cooker handle, thereby avoiding mistakenly gripping the cooker handle.
