When insects are sucked, the free ends of the two blocking pieces 503 can be relatively separated to form a funnel-shaped passage opening under the suction action of the fan, so that the insects can enter. When the fan 6 is closed and the insects do not need to be sucked, the free ends of the two blocking pieces 503 can be overlapped to close the lower end opening of the insect collecting cavity, so that the insects are prevented from escaping.

Further preferably, the insect suction head 4 is a frustum structure 401 which is formed by a plurality of valve flaps in a surrounding manner and has a large top and a small bottom, an insect inlet hole communicated with the insect inlet channel 3 is formed in the frustum structure 401 along the central line of the frustum structure, an adjusting block 402 which moves up and down relatively along the frustum structure is sleeved on the periphery of the frustum structure 401, an inner hole of the adjusting block 402 is provided with a conical surface 403 which has a large top and a small bottom, and a small-diameter hole wall of the conical surface 403 is in close contact fit with the outer peripheral surface of the frustum structure 401 during adjustment. When the adjusting block 402 moves upwards during adjustment, the small-diameter hole wall of the adjusting block 402 tightens the valve flap inwards to reduce the caliber of the insect sucking head. Conversely, when the adjusting block 402 moves downwards, the adjusting block 402 releases the valve clack, and the valve clack expands outwards under the action of self elasticity to increase the caliber of the insect sucking head.
