Socket with filtering circuit

Abstract

The invention discloses a socket with a filtering circuit. The socket comprises a power module, a shell, electrode sheets, a pressure sensor, a single chip and a relay, wherein socket holes are formed in the shell; two electrode sheets are arranged on the inner wall of the shell, corresponding to the socket holes; the pressure sensor is arranged between the two electrode sheets; a signal detected by the pressure sensor is transmitted to the single chip; the single chip is used for controlling the relay to act according to the received signal from the pressure sensor; the power module is used for supplying direct current power to the single chip; a sampling circuit, a filtering circuit and an amplifying circuit are successively arranged between the pressure sensor and the single chip; the filtering circuit comprises an operational amplifier A1, an operational amplifier A2 and a controllable precise stable voltage source Q5; a resistor R6 is serially connected between a cathode of the controllable precise stable voltage source Q5 and an inverted input end of the operational amplifier A1. The socket can prevent electric shock and has the advantage of enhancing socket safety.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to a socket with a filter circuit. Background technique [0002] At present, electricity has become an indispensable source of energy in people's lives.
