Abstract:
A flow path switching valve is provided. The flow path switching valve comprises: a valve body which has, at one side thereof, an inflow pipe and first and second outflow pipes, and which includes an inflow hole corresponding to one end of the inflow pipe, and first and second cam accommodating grooves corresponding to one end of each of the first and second outflow pipes; a cam disc including first and second cams accommodated, respectively, in the first and second cam accommodating grooves so as to block the outflow of a specific gas, a first and a second cam compressing protrusion, which compresses the first cam and/or the second cam so as to switch the flow path of the specific gas, and a first or a second cam compressing protrusion, which compresses either the first cam or the second cam so as to block the outflow of the specific gas; a cover coupled to the valve body while covering the cam disc; and a motor which is provided on the cover, and which rotates the cam disc so as to switch the flow path of the specific gas. The motor switches the flow path of the specific gas so that the specific gas flows out to the outside if the concentration of the specific gas at the location to which the specific gas is supplied is higher than a set value, and switches the flow path of the specific gas so that the specific gas flows out to the location to which the specific gas is supplied if the concentration of the specific gas at the location to which the specific gas is supplied is lower than the set value.
