The waste gas not only pollutes the environment, but also may harm the health of operators. Therefore, the waste gas needs to be treated. In use, the existing waste gas treatment device usually filters the waste gas by means of a filter screen. In order to avoid the filter screen from being blocked, the filter screen needs to be cleaned regularly. The existing cleaning methods usually have two kinds. One is to disassemble and clean the filter screen. The other is to clean the filter screen by means of a cleaning structure. However, in operation, the two methods both need the fan to stop running, which reduces the waste gas treatment efficiency. Therefore, the waste gas treatment device for cigarette case printing is proposed. CONTENT OF THE UTILITY MODEL
