摘要
The device according to the invention for catching insects, spiders and other small animals of this type by means of a pulse sucker contains a cylindrical housing part (2), a piston (4), a suction tube (3) and a compression spring (5). The compression spring (1) is arranged between the piston (4) and the suction tube (3) in the interior of the cylindrical housing part (2). The suction tube (3), which is operatively connected to the piston (4) via the compression spring (5), is guided displaceably in the axial direction and movably in a leadthrough (9) in the front wall (6) of the cylindrical housing part (2). On the suction-tube side, the piston (4) has latching means which are provided for latching and locking in a retaining device (16) arranged for this purpose in the base part of the suction tube (3), and which can be unlocked via a trigger (10) which can be operated from the outside. In order to actuate the pulse sucker (1), the suction tube (3) is pushed into the cylinder until the piston (4) arrives in the retaining device (16) in the base part (7) of the suction tube (3). To trigger a catching operation, the suction tube (3) is brought by the piston (4) into the triggering position. Actuation of the trigger (10) unlocks the piston (4). The compression spring (5) firstly causes the suction tube (3) to be pushed even further out of the cylinder until the base part of the suction tube (3) is on the inside of the front cylinder wall (6), and, secondly, the piston (4) to be pressed in the direction of the cylinder base (8), thus producing a negative pressure in the cylinder interior between the piston (4) and the base part (7) of the suction tube (3). The resultant stream of air sucks an insect located in front of the suction tube into the suction tube.
