Definitions

  • the present invention relates to the cleaning of paved surfaces in a domestic situation by the use of a portable and hand held blower to move debris to an acceptable location.
  • the best way of cleaning paved services in a domestic situation is to use a hose to wash the paved surface down.
  • the hosing of driveways and foot paths is particularly useful since the jet of water transports both large debris such as fallen leaves, and small debris such as dirt and dust particles. Furthermore, such small debris are included within the flow of water and accordingly no dust is generated as would be the case if the footpath were swept with a broom, for example.
  • blowers are preferred.
  • these blowers are not perfect in that although the dust stirred up by such blowers is directed away from the operator, substantial amounts of dust are created and this can be disadvantageous, especially where family members or neighbours are asthmatics or suffer from other respiratory complaints.
  • the genesis of the present invention is a desire to enable portable hand held blowers to be used to clean paved surfaces in a domestic situation, but to reduce, or at least ameliorate, the amount of air borne dust generated by such use.
  • a portable hand held blower with dust suppression capability comprising a portable engine coupled with a fan having an air inlet and an air outlet through which air flows, a portable water reservoir associated with said blower and having a water outlet tube leading into said air flow, and water injection means to inject water out of said outlet tube to thereby generate a dust suppressing mist of water entrained with said flow of air.
  • a portable hand held blower having an air outlet arranged to provide an air flow which blows debris over or along a hard surface
  • the improvement comprising a portable water reservoir associated with said blower, having a water outlet tube leading into said air flow, and water injection means to inject water into said water outlet tube to generate a dust suppressing mist of water entrained with the flow of air exiting from said air outlet.
  • a method of entraining a dust suppressing mist of water into the flow of air exiting an air outlet of a portable hand held blower comprising the step of: (i) injecting water into said air flow.
  • a portable and hand held sprayer for insecticides, fungicides, and the like comprising the abovementioned portable hand held blower.
  • Fig. 1 is a perspective view of the portable hand held blower of the preferred embodiment looking from the front and from the left-hand side (the references to left and right being with respect to the left and right hands of the operator during use)
  • Fig. 2 is a side view of the blower looking from the right,
  • Fig. 3 is a rear view of the blower
  • Fig. 4 is a front view of the blower
  • Fig. 5 is a side view of the blower looking from the left
  • Fig. 6 is a plan view of the blower
  • Fig. 7 is an inverted plan of view of the blower
  • Fig. 8 is a longitudinal cross-sectional view through the blower outlet and to an enlarged-scale.
  • the portable hand held blower 10 has a housing 11 within which is located a small internal combustion engine and a centrifugal fan (both not illustrated).
  • the housing 11 has a handle 12 by means of which the blower 10 can be held and orientated.
  • the blower 10 also has a U-shaped foot 13 which enables the blower 10 to be supported on a flat surface in the manner illustrated in Fig. 1. In the above respects the blower 10 is substantially conventional.
  • the blower 10 also has a lance 14 which is fabricated in two sections 14A and 14B each of which is alike and each of which has a thread at either end which enables the two sections to be threadably engaged.
  • the lance has an output nozzle 15 which concentrates the flow of air as it exits the lance 14.
  • the lance 14 and output nozzle 15 are able to be threadably engaged with, and disengaged from, the remainder of the blower 10.
  • the lance is able to be disassembled into three sections thereby enabling the blower and lance to be packed within a compact cardboard box. If desired, none, one or two sections (or more) of the lance 14 can be used. With none the nozzle 15 attaches directly to the housing 11.
  • a separate water reservoir 20 which has a lid 21 which is releasably secured to the body of the reservoir. Passing through the lid 21 is an air pump handle 22 and extending from the reservoir is an output tube 23. A carry strap 24 enables the water reservoir to be carried by the operator in addition to the operator holding the blower 10 in one hand.
  • a suitable candidate for the reservoir 20 is a conventional air pump action insecticide or herbicide sprayer with its sprayer removed.
  • the tube 23 is attached to the housing 11 and extends along the top of the lance 14 and into the output nozzle 15. As best seen in Fig. 8, the tube 23 terminates in an opening which functions to some extent as a Venturi and which is directed towards the open end of the output nozzle 15. As a consequence, water which is pumped from the reservoir 20 through the tube 23 exits from the tube in the same direction as the air exits from the output nozzle 15. This has the result that the water is entrained in the air exiting from the lance 14 as a mist of fine water droplets. The fineness of the mist increases as the speed of the blower 10 increases.
  • the pump handle 22 is reciprocated so as to pressurise the air within the water reservoir 20 and above the water contained in the water reservoir 20.
  • the operator then starts the internal combustion engine of the blower 10, normally with the blower 10 positioned on the ground.
  • the operator places the carry strap 14 over his right shoulder so as to place the water reservoir 20 adjacent his left hip.
  • the operator then holds the blower 10 by the carry handle 12 and uses it to steer the blower 10 so as to direct the output from the lance 14 to the footpath or driveway to be cleaned.
  • Exiting from the nozzle 15 of the lance 14 is a concentrated flow of air including an entrained water mist.
  • This combined flow not only removes major debris such as leaves from the pathway, but also wets fine particles such as dust which are then sufficiently heavy to fall immediately to the ground. The result is that the major debris such as leaves are blown to their intended destination with a minimum of airborne dust.
  • the water reservoir 20 typically has a volume of approximately 5 L. Typically, about 1 L of this is used to sweep a footpath wide enough for single file movement (eg 1 metre in width) having a distance of approximately 50 m. As a consequence, the volume of water consumed in sweeping the paths and driveway(s) of a domestic home is very small and very much less than the volume of water which would be used to hose down the same paths and driveway(s).
  • the same apparatus can be used by a home owner for the second purpose of spraying insecticides, fungicides or herbicides.
  • insecticides for example, one or more fruit trees (or a bed of tomato plants) in a backyard garden can be quickly sprayed by the above- mentioned apparatus by adding some insecticide (or fungicide etc) to the water located within the reservoir 20.
  • the entire blower 10 is preferably manipulated, for example preferably by holding both the handle 12 and foot 13, in order to be able to direct the spray to the desired tree or garden.
  • only a single hand on the handle 12 can suffice.
  • the water reservoir 20 can be sized to suit the application concerned. For some applications, a large water reservoir 20 which can be carried from place to place, but not always supported from the operator's shoulder, can be used.
  • the water reservoir 20 can be provided with a small battery-powered electric water pump.
  • the blower 10 can be powered by an electric motor rather than an internal combustion engine.
