Definitions

  • This invention relates to an improvement in an apparatus for spraying chemicals on an object in a distant place and/or into a narrow opening.
  • the known apparatuses of this kind for spraying chemicals on an object in a distant place include an apparatus in which a front end of a coiled flexible tube is connected to an ejection head fixed to a front end of an expansible rod provided independently of the flexible tube, a base end of the flexible tube being connected to a nozzle pressing cap fixed to a nozzle member of an aerosol bomb so that the flexible tube expands in accordance with the expansion of the rod, the chemicals in the bomb being sprayed in an atomized state from the ejection head when the nozzle pressing cap is pressed.
  • a front end of a coiled flexible tube is connected to an ejection head fixed to a front end of an expansible rod provided independently of the flexible tube
  • a base end of the flexible tube being connected to a nozzle pressing cap fixed to a nozzle member of an aerosol bomb so that the flexible tube expands in accordance with the expansion of the rod, the chemicals in the bomb being sprayed in an atomized state from the ejection head when the nozzle pressing cap
  • an expansible rod and a flexible tube have separately formed structures. Consequently, a stable controllability of the apparatus as a whole is low, and, moreover, while the apparatus is operated, the flexible tube interferes with another part and disengages from the nozzle member and the ejection head, whereby a chemicals spraying efficiency is lowered in some cases. Also, forming a means for urging the flexible tube so that the tube is stored in a coiled state is complicated, and this causes the cost of manufacturing the apparatus as a whole to increase. Therefore, such an apparatus is economically disadvantageous.
  • the known apparatuses of this kind for spraying chemicals into a narrow opening include an apparatus in which a fine, non-flexible steel pipe whose length usually does not exceed 15cm is connected to an aerosol valve or an apparatus in which a nozzle member whose thickness is usually not less than 1.5cm is connected to spray means such as a manual or automatic pressure atomizer.
  • a nozzle member whose thickness is usually not less than 1.5cm is connected to spray means such as a manual or automatic pressure atomizer.
  • An aerosol spraying auxiliary tool is disclosed in the official gazette of Japanese Utility Model Laid-Open No. 141809/1976 as means for solving the above problem of the prior art.
  • the auxiliary tool solves the conventional technical problem previously described, it is inconvenient to handle the tool because there is no means for storing a free long flexible tube when it is not used because a telescopic rod is contracted.
  • the spray direction is specified in the direction perpendicular to the central axis of the telescopic rod, a problem that the purpose is limited is not solved.
  • an apparatus for spraying chemicals on an object in the distance and/or into a narrow opening comprising a flexible tube longer than a most-expanded operating pole of a telescopic rod structure or a rod antenna structure made by telescopically connecting plural pipe rods one another and loosely fitted into the operating pole and whose front end is connected to the base of a nozzle member provided at the front end of the foremost pipe rod and whose base end is connected to an ejection control button which can be attached to or detached from a valve stem of an aerosol bomb or spray means such as a manual or automatic pressure atomizer at the side of the base end pipe rod forming the operating pole.
  • This apparatus is hereinafter designated "basic spray wand”.
  • the nozzle member can be tilted, bent or rotated to the basic spray wand.
  • the foremost pipe rod of the operating pole may be fixed or removable and made out of plastics material that can keep its bent state.
  • a part or the whole of the foremost pipe rod of the operating pole may be made out of a flexible tube covered by a plastic tube that can keep its bent state.
  • the basic spray wand may comprise a foremost pipe rod forming the operating pole which is constituted with a plastic tube whose bent state is kept and to whose front end a nozzle member is set and the base of the plastic tube is fixedly or removably connected to the flexible tube of the next stage pipe rod.
  • the invention provides an apparatus for spraying chemicals on an object in a distant place and/or into a narrow opening, in which a flexible tube longer than a most-expanded operating pole of a telescopic rod structure or a rod antenna structure made by telescopically connected plural pipe rods one is loosely fitted into the operating pole, a pipe having a chemicals channel perpendicular to the central axis of a foremost pipe rod forming the operating pole is provided at the front end of the foremost pipe rod, a shell provided with a nozzle member connecting with the chemicals channel is rotatably set to the pipe having the chemicals channel, and an ejection control button which can be attached to or detached from a valve stem of an aerosol bomb or spray means such as a manual or automatic pressure atomizer is provided at the base end of the flexible tube.
  • the invention provides an apparatus for spraying chemicals on an object in a distant place and/or into a narrow opening, in which a pipe rod made of an elastic and flexible material such as a fine stainless steel pipe and longer than a comparatively long operating pole made of a hard material is inserted into the operating pole with a rod antenna structure and the front end of a flexible tube having an ejection control button which can be attached to or detached from a valve stem of an aerosol bomb or spray means such as a manual or automatic pressure atomizer is connected to the base of the pipe rod.
  • a pipe rod made of an elastic and flexible material such as a fine stainless steel pipe and longer than a comparatively long operating pole made of a hard material
  • the apparatus may further comprise fixed or removable protective means for avoiding an attack of noxious animals such as wasps and snakes on any place of operating poles when used for controlling harmful animals.
  • the apparatus may further comprise a longer flexible tube a part of which is coiled on the surface of the base-end part of the operating pole, at a hand grip part, in the basic spray wand to ease possible plant leaf frostbite.
  • the apparatus may further comprise a fixed or removable lighting means such as a small flashlamp on the foremost pipe rod forming an operating pole in order to throw light over the place on which chemicals are sprayed.
  • a fixed or removable lighting means such as a small flashlamp on the foremost pipe rod forming an operating pole in order to throw light over the place on which chemicals are sprayed.
