Technology and the content of the invention of garden sprayerd

Technical field The utility model belongs to the field of [0001] tools, in particular to the back sprayers . The technical background Now [0002] garden sprayerd, the piston rod hole and piston rod cylinder at the top of the piston rod wear because without gap seal, make operation liquid cylinder will leak out from the top, because the operator load carrying forward body, liquid leaking out from the top of the cylinder flow to the operator's back, pollution corrosion body. The content of the invention [0003] the design purpose: in view of the existing garden sprayerd was improved, garden sprayers backpack  design capable of preventing leaking out from the top of the cylinder of liquid pollution control body of the sprayer. In order to realize the aim of the design of [0004], the following technical scheme: which comprises a barrel body, shoulder straps, joystick, nozzles and other parts, which is characterized in that: the top of the barrel body is arranged to the edge of the middle slope low rise, and near the opening of the cylinder around each set drainage groove. Characteristics compared with the prior art, the utility model [0005]: with the proposal, because the design of the slope to the edge set into low rise in the middle of the top of the cylinder, and near the cylinder mouth around each set drainage groove, liquid leakage out of the overland flow to the drainage groove back bucket, so compared with the existing backpack garden sprayers , has the advantages of liquid pollution preventing leaking out from the top of the cylinder body of the manipulator.
