专利汇可以提供Sprayer attachment for leaf blower专利检索，专利查询，专利分析的服务。并且A garden spray attachment for use with high-powered leaf blowers and the like, comprising a tank or container for insecticide liquid, having a discharge spout at the bottom which is controlled as to the rate of flow by a manually adjustable valve. The tank has means for attaching it to the structural parts of the leaf blower, preferably the casing of the centrifugal air impeller, in such a manner that the discharge line from the tank can be brought directly to the air intake of the impeller. The attachment additionally includes a discharge conduit which has a nozzle portion that is movable with respect to the remainder, so as to direct fluid passing through it in different directions. The discharge conduit includes an adapter fitting which in most cases has a rectangular portion adapted to be releasably secured to the discharge duct of the leaf blower. The discharge conduit is preferably of cylindrical large-diameter plastic tubing having a helical wire reinforcement. The fitting of the discharge conduit has a circular portion adapted to mate with and be secured to the cylindrical conduit tubing. For directing the moveable nozzle portion of the discharge conduit, a flexible line such as a plastic rope or the like passes through it and is secured to the adapter fitting, said line being manually manipulated as by pulling, and causing bending of the conduit so as to direct the discharge spray to the desired areas.，下面是Sprayer attachment for leaf blower专利的具体信息内容。
