Smoke absorbing device

A smoke absorbing device makes a hollow housing as a carrier. A small fan is installed in a place over the housing; a ventilating inlet is formed in the front surface of the middle of the housing; the small fan guides wind to passes through the ventilating inlet and then to upwardly blow; as long as a smoker breathes out smoke toward the ventilating inlet, smoke can be absorbed into the ventilating inlet and then spread out toward the air; a smoke ash box is manufactured under the housing; a separation layer is formed between the smoke ash box and the ventilating inlet; a hole is formed in the front surface over the smoke ash box and a cigarette end clip is disposed outside the hole; upon smoking, the cigarette after ignited can be placed into the hole; the cigarette end can be fixed in the smoke ash box via the cigarette end clip; smoke of the cigarette caused by spontaneous combustion can be absorbed into the ventilating inlet; smoke ash after combustion of the cigarette can be collected into the cigarette ash box; and a smoke ash box outlet is formed in the right side of the cigarette end clip.
