Intelligent anti-spilling pot cover with filter circuit

Abstract

The invention discloses an intelligent anti-spilling pot cover with a filter circuit. The pot cover comprises a lifting handle, air pipes, an air vent and a pot cover plate, wherein the lifting handle is disposed on the top end of the pot cover plate; the air pipes are inlaid in the pot cover plate; one end of each air pipe is connected to a compressor inside the lifting handle, and the other end of the air pipe is equipped with a steel bead; the diameter of the outlet of the air pipe is smaller than the diameter of the steel bead; the quantity of the air pipes is more than one; the multiple air pipes are uniformly distributed along circumference of the pot cover; a single-chip microcomputer, a power source module and a compressor are disposed inside the lifting handle; the air vent is formed in the pot cover plate; a pressure sensor is disposed inside the air vent; signals of the pressure sensor are transmitted to the single-chip microcomputer; the single-chip microcomputer controls the compressor to act according to the received signals; the power source module is used to provide power supply for the single-chip microcomputer and the compressor; and a sampling circuit, the filter circuit and an amplifying circuit are connected successively between the pressure sensor and the single-chip microcomputer. The filter circuit comprises an operational amplifier A1 and an operational amplifier A2, wherein a series circuit composed of a resistor R1 and a resistor R2 is connected to an inverted input end of the operational amplifier A1. The pot cover has the advantages that pot spilling is avoided.
