Exhaust control system used for sanitation system

Abstract

The invention discloses an exhaust control system used for a sanitation system. The exhaust control system comprises an exhaust fan, a power supply module U1, an electromagnetic relay J1, a time relay KT, a switch K1, a pressure-sensitive resistor R2, a triode Q1 and a voltage comparator U2, wherein a group of normally closed contacts of the time relay KT are connected with a power supply loop of the exhaust fan in series, and a group of normally opened contacts of the electromagnetic relay J1 are connected to the power supply loop of the exhaust fan in series. The exhaust control system further comprises an exhaust pipeline, a drying agent and a catalyst, wherein the catalyst and the drying agent are arranged in the exhaust pipeline, and gas discharged by the exhaust pipeline is processed. The system has the advantages of simple circuit, low cost, strong operability, and capability of automatically removing dirty gas in the room and a closestool, purifying indoor environment and improving the toilet entrance environment.

Description

technical field [0001] The invention relates to the technical field of exhaust control used in sanitary systems in households or public places, in particular to an exhaust control system for sanitary systems.
