Patent number: 11707152Abstract: 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.Type: GrantFiled: November 1, 2017Date of Patent: July 25, 2023Inventors: Feng Peng, Fan Zhang
