Definitions

  • the present invention relates to a portable liquid sprayer, especially for the treatment of vegetation.
  • Portable sprayers are known from the prior art, making it possible to treat small area surfaces and / or hard-to-reach surfaces.
  • such a portable sprayer comprises a reservoir for containing a phytosanitary liquid, on which are mounted a hand pump (or possibly motorized) and a flexible conduit connected to a lance for projecting the liquid on plants to be treated.
  • Such a handle is not adapted to allow gripping of the sprayer, on the one hand because of its poor ergonomic shape, and secondly because it is, by nature, movable relative to the body of the sprayer.
  • the present invention is intended to facilitate the gripping of such a sprayer.
  • gripping the sprayer according to the invention is very easy and stable for virtually any orientation of the sprayer relative to the hand of the operator.
  • the present invention also relates to a sprayer comprising a tank according to the above.
  • the sprayer comprises a reservoir 1 having itself preferably an upper part 3 called “head” and a lower part 5 called “body”.
  • the head 3 and the body 5 are preferably injected thermoplastic parts, welded together.
  • a manual pumping device known per se, including a handle 7 for putting the tank 1 under pressure.
  • the manual pumping device can be replaced by an electric pumping device.
  • the sprayer according to the invention also comprises an outlet pipe 9 fixed to the head 3, also known per se.
  • This outlet pipe is adapted to be connected to a flexible pipe and a spray lance, not shown, for projecting the liquid contained in the tank 1 on the surface to be treated.
  • the sprayer according to the invention comprises a knob 11 preferably located on the head 3.
  • this knob 11 is situated on an inclined plane 13 formed on one side of the head 3.
  • the outlet pipe 9 and the knob 11 are preferably both located on the inclined plane 13.
  • knob 11 is preferably located in the plane of symmetry P of the tank according to the invention.
  • knob means a gripping member adapted to be housed in the palm of the hand, as opposed to a “handle” such as the handle 7, which defines a closed contour to be tightened by the fingers of the hand.
  • the knob 11 is formed in one piece with the head 3.
  • the knob 11 is a part comprising a plurality of ribs 17.
  • the knob 11 has a substantially circular shape.
  • the knob 11 may have a substantially oblong shape, the longest of which extends perpendicularly to the plane of symmetry P.
  • the knob 11 has a curved shape, that is to say, a form of tab.
  • the knob 11 is a part manufactured separately from the head 3, and is designed to be removably attached to this head.
  • Convenient fastening means is obtained with a thread 21 formed on the head 3.
  • the knob 11 it is possible for the knob 11 to include a hollow portion 23 inside which there is a dosing scale of treatment product.
  • this dosage scale may comprise rods 25 having different heights, each of these rods being associated with a graduation value 27.
  • the knob 11 is formed in one piece with the head 3 of the sprayer.
  • this knob is hollow, and closed by a cap 29 can be fixed for example by clipping.
  • this operculum 29 gives the knob 11 the appearance of a massive member, as can be seen in FIG.
  • the knob 11 attached to the head 3 of the tank according to the invention allows a particularly easy gripping of the tank.
  • This knob can indeed be housed in the palm of the hand, and this for virtually any orientation of the sprayer relative to the hand of the operator.
  • This knob allows the tank to be easily and very easily grasped with one hand and, if necessary, to perform certain operations with the other hand, such as filling and emptying the tank after rinsing, screwing / unscrewing of the hand pump, immobilization of the tank during pumping, etc.
  • FIGS. 10 to 12 is particularly advantageous when it is desired to incorporate in the sprayer, in a simple manner, a treatment product dosing system.
  • the amount of treatment product introduced into the hollow portion 23 of the pommel 11 is indicated by the graduation 27 corresponding to the largest stick 25 covered by the treatment product.
  • the contents of the pommel 11 are emptied inside the sprayer tank, and the pommel 11 is then screwed onto the thread 21 disposed on the head 3.
  • this position of the knob 11 on the inclined plane 13 makes it possible to bring this knob closer to the axis of the sprayer, and thus to contribute to maintaining this sprayer in a substantially vertical position when it is grasped by the knob 11.
  • knob 11 is located substantially in the plane of symmetry P of the sprayer.
