Patent ID: 8074395

Claim:
A pulsating suction device for catching insects, spiders and other small animals, comprising: a cylindrical housing having an interior and defining a longitudinal axis, said housing having a front wall with a feedthrough and a closed rear wall; a suction tube having a piston-proximal end and a suction end guided in the feedthrough for movement in an axial direction; a piston arranged for movement in the axial direction inside the housing and relative to the suction tube and having a suction-tube-proximal end formed with a latching member; a spring-elastic element extending between the piston and the suction tube in the interior of the housing, wherein a first end of the spring-elastic element is attached to the piston and a second end of the spring-elastic element is attached to the suction tube to thereby operatively connect the piston with the suction tube; a holding unit arranged in the piston-proximal end of the suction tube and including a locking member for releasably locking with the latching member, when the suction tube is moved in the axial direction against the piston; and a trigger arranged proximate the front wall of the housing and actuated from outside to release the latching member of the piston from the locking member of the suction tube to thereby cause a spring force from the spring-elastic element to move the piston away from the suction tube toward the closed rear wall of the housing and produce a reduced pressure inside the housing, drawing in insects, spiders and other small animals.
