14. A cigarette smoke generating and collecting system, comprising: a cigarette smoke generator; and a cigarette smoke collection unit, wherein the cigarette smoke generator comprises: one or more solenoid valves for sequentially passing and blocking cigarette smoke from one or more cigarettes arranged in one row; one or more cigarette smoke intake lines for sucking the cigarette smoke; one or more cigarette smoke exhaust lines for discharging the cigarette smoke to a collection unit connecting line; and one or more pumps connected to the one or more cigarette smoke intake lines and the one or more cigarette smoke exhaust lines, the one or more pumps configured to alternately operate intake and exhaust of the cigarette smoke, and wherein the cigarette smoke collection unit comprises: one or more Cambridge filters for collecting particulate substances; and an impinger for collecting gaseous substances, and the cigarette smoke generating and collecting system, further comprising: a control unit for controlling operation of the cigarette smoke generator and the cigarette smoke collection unit.

15. The cigarette smoke generating and collecting system of claim 14 , wherein the one or more pumps are in pairs, and each of the pumps of the pairs of pumps alternately performs intake or exhaust to thereby simultaneously operate the intake and exhaust.

16. A cigarette smoke generating and collecting method, comprising: arranging one or more cigarettes in a line in each row; igniting the one or more cigarettes by moving an automatic ignition device up and down or left and right; sucking cigarette smoke from the one or more cigarettes independently and sequentially for each row using a solenoid valve; sucking the cigarette smoke using a first pump one of a pair of pumps, wherein the pair of pumps is configured to alternately operate intake and exhaust of the cigarette smoke; simultaneously with the step of sucking, discharging the cigarette smoke using a second pump of the pair of pumps; and separating and collecting the discharged cigarette smoke into particulate substances and gaseous substances, using one or more Cambridge filters and an impinger included in a cigarette smoke collection unit, wherein the steps of sucking and discharging the cigarette smoke are repeated.

17. The cigarette smoke generating and collecting method of claim 16 , further comprising: pushing and removing at once the one or more cigarettes for which the cigarette smoke has been collected; and cleaning a cigarette smoke intake port, a cigarette smoke intake unit, cigarette smoke intake lines, and cigarette smoke exhaust lines through outside air.
