Abstract: A portable, hand held, air suction and blower unit comprising an air inlet assembly with sequentially arranged nozzle, flexible inlet tube, and diffuser, all detachably connected to the front end of the unit body. The diffuser cooperates with the front end of the body to form a bayonet type joint therebetween. An air inlet passage extends rearwardly from the front end of the body to the tangential fan which is journaled at the rear of the body. The fan is powered by a manually wound flat spiral spring, which spring drives the fan through a gear train. An air outlet passage extends forwardly from the fan to an outlet opening also located at the front of the unit body. A removable, pervious receptacle, with an open forward end, is located in the front portion of the air inlet passage and serves to collect particles or objects which are drawn into the body by the flowing air.

Abstract: A motorized vacuum unit fitted with an intake nozzle that may be readily pointed towards a fly or other flying insect to catch and draw the flying insect into a mesh cage inside the unit. The nozzle is pivotably mounted to the body of the unit so that rotation of the nozzle provides access to the cage for emptying of its contents. A battery, motor and suction fan are mounted in the body which is fitted with a fixed handle surrounding a recess in the body to enable grasping of the body by a hand of the user, with the axis of the handle parallel to the axis of the nozzle.
