Abstract: Disclosed are a circuit board assembly and a rice cooker, where the circuit board assembly includes: a housing, including a circuit board bracket and a fireproof cover fixing and covering the circuit board bracket, where the fireproof cover and the circuit board bracket are enclosed to define a fireproof cavity; and a circuit board, mounted on the circuit board bracket and accommodated in the fireproof cavity. The present disclosure provides a fireproof cover made of a fireproof material on the circuit board. The fireproof cover and the circuit board bracket may be fixed and covered to define a fireproof cavity, and the circuit board may be accommodated in the fireproof cavity. In this way, the circuit board may be isolated from the outside, to prevent the fire from spreading when the circuit board catches fire, to ensure the safety of users' lives and property.

Abstract: Disclosed is a long-afterglow luminescent material, comprising A) at least one light-absorbing agent, B) at least one luminescent agent, and C) at least one photochemical cache agent. The light-absorbing agent and the luminescent agent are compounds having different structures, and the cache agent is selected from one or more compounds of formula (I), (II) and/or (III). The material has luminescent intensity reaching the level of commercialized inorganic long-afterglow powder SrAl2O4:Eu2+, Dy3+, and can emit light when the exciting light is turned off with a light emitting time up to 100 ms to 3600 s.

Abstract: Disclosed is a cooking appliance that includes a cooker body assembly, a lid assembly, a weighing sensor, a first control panel, and a second control panel. The cooker body assembly includes a housing and an inner pot disposed inside the housing. The lid assembly can be opened and closed to cover the inner pot. The first control panel is disposed on the lid assembly, and the second control panel is disposed on the housing. The weighing sensor is electrically connected to the second control panel. According to this disclosure, the second control panel is disposed on the housing, so that the second control panel does not flip to the rear side together with the lid assembly when the lid assembly is opened to add food or water.

Abstract: A control method of a cooking appliance includes acquiring a current weight of a container of the cooking appliance with a food material through a weighing device of the cooking appliance, calculating a weight of the food material in the container according to the current weight of the container with the food material and an initial weight of the container without the food material, and determining a calorie amount of the food material according to the weight of the food material and a type of the food material.

Abstract: A liquid crystal panel comprises a first substrate (11) and a second substrate (21) facing each other. A polarizer (30) is adhered to one side of the first substrate (11) orientated away from the second substrate (21). The liquid crystal panel further comprises a touch type input structure which is adhered on the outer surface of the polarizer (30) orientated away from the first substrate (11) to identify a touch signal; and an electromagnetic type antenna array at least comprising a first-direction conductive wire (51) and a second-direction conductive wire (52). The first-direction conductive wire (51) and the second-direction conductive wire (52) are respectively made of conductive material, and are formed on any one film between the first substrate (11) and the second substrate (21). The antenna array is used to identify an electromagnetic signal.
