An assembly type ventilation reagent cabinet is provided to use the space of a laboratory effectively and to prevent power waste by using a sensing switch detecting the opening and closing of a door and a control unit effectively operating a delivery fan according to the opening and closing of the door. In an assembly type ventilation reagent cabinet, a body(100) is composed of: a reagent compartment opened and closed by a door installed on the front side, to store reagents; an exhaust hole formed at the back side to communicate with reagent compartment; upper combining perforated holes formed on the upside; lower combining perforated holes formed at the lower side; left combining perforated holes formed on the left sides; and right combining perforated holes formed on the right sides. An external air inflow unit has a penetrating hole formed from the outside of the door to the inside; a blocking plate installed at an inlet of the inside of the penetrating hole; and a filter mounted in the penetrating hole. A sensing switch is turned on or off according to the opening and closing of the door. An exhaust hood(400) is installed at the back side of the body to receive the harmful gas generated from the reagents stored in the reagent compartment, from the exhaust hole and to deliver the harmful gas to the outdoor side by a delivery fan. A control unit(500) comprises a timer sensor and a control sensor. If the timer sensor detects an on-signal transmitted from the sensing switch, the delivery fan is repeatedly operated and stopped according to a set pattern and the blocking plate is opened by the flow of air while the delivery fan is operated. If the timer sensor detects an off-signal transmitted from the sensing switch, the timer sensor stops repeating of the operation and stop of the delivery fan. The control sensor continuously operates the delivery fan if the off-signal transmitted from the sensing switch is detected.
