The resistors R1, R3 and R4 are used for voltage division, and the capacitors C1 and C2 are used for filtering.
After the first cover 1 is fastened to or separated from the pot body 3, the fifth pin a5 does not form a loop, so the control board 5 cannot detect the voltage of the heating pipe zero line interface ACN2 at the pot cover through the voltage detection circuit 51. After the second cover 2 is fastened with the pot body 3, the second upper coupler 42 and the lower coupler 43 are inserted together, and the second detection circuit 21 is electrically conducted with the control board 5, so that the control board 5 can detect the voltage of the fifth contact pin a5 corresponding to the heating pipe zero line interface ACN2 through the voltage detection circuit 51; on the contrary, when the second cover body 2 is separated from the pot body 3, the voltage of the heating pipe zero line interface ACN2 can not be detected.
