The invention creation general discloses the buttocks cleaning type available seat which a kind of monolithic integrated circuit controlled to guard against the electricity wall installment, belonged to the shrapnel and the technical application domain, the hot other design buttocks cleaning type available seat grounding and the basic insulation simultaneously the expiration was is for the purpose of protecting the personal safety to guard against the electricity wall technology. The invention creation by zero grounding potential difference detector set, central processor and relay execution electric circuit order connection. The main characteristic is indirectly has the transformer in the grounding and the zero curve or anti- accommodates the reduced pressure electric circuit, through switching valve connection monolithic integrated circuit I/O input port. Between monolithic integrated circuit receive zero grounding voltage difference signal, when grounding charged real-time shuts off the grounding and the buttocks cleaning type place then electric heating tube power source, this invention creation suits each kind of buttocks cleaning type available seat each kind of control mode use. The invention creation design guards against the electricity wall technology, is for the purpose of earthing is unreliable or under the grounding actual effect environment to the personal safety protection. The implementation example heating element refers in particular to the use city electricity the electric heating tube.
