An embodiment of this invention is an adjustable wand for a carpet cleaning apparatus wherein the upper tube telescopes within a lower tube and allows lengthening of the wand. The lower nozzle is adjustable in that it allows rotation about the wand axis and allows removal of the nozzle. The preferred means for adjustment is a cam lock mechanism that tightens an adjustment clamp around the wand upper tube or nozzle neck.

A nozzle assembly of a vacuum cleaner is provided that includes a casing, a suction port, a drum brush, a fan, and a blocking plate. The drum brush is rotatably disposed in the casing so drum bristles hit a surface being cleaned. The fan is disposed in the casing to be rotated by air drawn in through the suction port so that the fan rotates the drum brush. The blocking plate is adjacent to the front of the fan to screen most of the fan except for a lower portion of the fan. The fan includes a circular fan body, a shaft member, and a plurality of blades. The inside edge of each of the blades is at a distance from the shaft member so that the drawn-in air passes through a space defined between the inside edge of each of the blades and the shaft member.

A cleaner includes a suction motor mounted in a cleaner main body, and generating a suction force; a filter for collecting dust or filth sucked by the suction force generated at the suction motor; a suction head connected with the filter by a suction tube, and sucking dust and filth on a floor; a brush installed in the suction head so as to ascend / descend in a vertical direction, and sweeping dust and foreign substances into the suction head; and a brush height control apparatus installed in the suction head, and making the brush ascend / descend in a vertical direction. The cleaner having a brush height control apparatus can prevent deterioration of a suction force and improving cleaning performance by constantly maintaining a gap between the suction head and the floor.

The invention discloses a plant protection unmanned aerial vehicle for plant sampling. The plant protection unmanned aerial vehicle includes a sample recovery case, a sample transporting slot, a driving motor, a blade protection rack fixing base, a sample collection shield, a camera and an unmanned aerial vehicle main body. Sample recovery case fixing racks are welded to bottom two sides of the unmanned aerial vehicle main body. The sample recovery case is welded to bottoms of the sample recovery case fixing racks. A device fixing rack is welded to one side of the bottom of the sample recoverycase. The bottom of the device fixing rack is provided with a device fixing base.
