DETAILED DESCRIPTION OF THE INVENTION

(5) The invention is a blower attachment and atomizing system that will allow use of any standard handheld or backpack leaf blower to spray pesticides, herbicides, fungicides or other liquids, thus providing greater reach and coverage than free-standing home sprayers currently on the market. The atomizing system comprises an atomizer, liquid tube, pressurized liquid container and a leaf blower.

(6) The blower attachment will attach to a hose that also is attached to a standard pump spray tank. The user will be able to choose different size tank such as a 1 gallon or 2 gallon handheld tank, or backpack 3 to 4 gallon tank. The tanks will be pressurized by a manual or powered pump that will push the liquid through the hose, through the atomizer end of the hose, and will be atomized by the blower. The pressurization of the liquid will allow the user to spray in high and low areas. The blower force along with the atomization of the liquid will allow users to disrupt bushes, shrubs and tree leaves to allow application of the atomized liquid throughout the foliage, including under leaves, on stems and other locations where insects may be located.

(7) With specific reference to the disclosed blower attachment, it is to be a universal attachment that will fit any standard handheld leaf blower or standard backpack blower and will be used to atomize and dispense insecticides and other liquids. A pressurized tank will allow the liquid to continually flow through the atomizer end, allowing users to spray high and low areas.

(8) In a preferred embodiment, the blower attachment is adjustably clamped to the exhaust end of the blower with a clamp, pins, screws, or similar means of attachment. A hose for transmitting liquid to be atomized will be attached to each of the pressurized tank acting as a liquid reservoir, as well as to the blower attachment utilizing one or more hose clip components. Such hose clip component(s) will preferably be embodied as horseshoe-shaped plastic clips integrated with the body of the attachment, into which the flexible hose body may be stably and removably inserted. The end of the hose opposite the reservoir tank will comprise an atomizer, with a narrowed diameter to create increased pressure and expel the pumped liquid from the hose as an atomized spray. The body of the attachment will further comprise at least one hose hole into which the atomizer at the end of the hose may be inserted. A preferred design of the hose for such arrangement includes a bend of approximately 90% at the point where the atomizer is attached to the hose, allowing the atomizer to emanate outward at a roughly right angle from the hose for insertion into the hose hole.

(9) In a preferred embodiment, the clip body of the blower attachment will be manufactured using injection molding or a similar type of plastic molding, using a plastic such as PET, PETE, polyester, polypropylene, HDPE, PVC or a similar material. The atomizer end of the hose will preferably be made similarly.

(10) In a preferred embodiment, such hose hole(s) will be bored into a post emanating from the attachment clip body, placing the atomizer in a position roughly in the center of the blower exhaust pipe to which the attachment is clamped. The atomizer will fit into such hole facing away from the blower so that the atomized liquid particles eject in the same direction as the blower air flow, thus allowing the blower air flow to carry away and disperse the atomized liquid particles.

(11) In an alternate embodiment, the hose may comprise a diffuser at the end, such diffuser configured as a mesh or series of concentric circles to further break up and atomize the liquid upon ejection. In another alternate embodiment, the hose may further comprise an adjustment mechanism to regulate the flow of liquid through the hose or atomized fluid ejected from the hose. Such mechanism may take the form of a knob attached to a ball valve or other similar valve-based system. In a more preferred embodiment, the atomizer end itself comprises a turn dial for flow regulation.

(12) A liquid atomizing and dispersal system, comprising clip body, blower, hose and reservoir tank, may be used for spraying any liquid useful in an outdoor setting, including but not limited to pesticides, herbicides, fertilizers, mold and mildew removers or detergents.

DETAILED DESCRIPTION OF THE DRAWINGS

(13) FIG. 1 is a drawing of the blower attachment 10 alone, comprising clip body 30 with proximal end 31 and distal end 32, with clamp slots 33 for securing the clamp (not pictured) in place over the exhaust pipe 61 (not pictured) of a blower and collar 36 comprising hose clip 37. Backstop 38 is an emanation from the clip body made to fit against the rim of such blower exhaust. Integral with the clip body 30 is hose post 34 emanating downward from near the distal end and comprising hose holes 35. When in use, the hose 70 (not pictured) will be clipped into hose clip 72, then continue downward for insertion into one of the hose holes 35.

(14) FIG. 2 shows the blower attachment 10 with hose 70 extending from tank 50, such hose clipped into hose clip 37, with the hose ending in atomizer end 71, such end centered within a hose hole 35.

(15) FIG. 3 shows blower attachment 10, with hose 70 clipped into hose clip 37 within collar 36, with clip body 30 clamped at its proximal end 31 onto blower exhaust pipe 61 by clamp 40, which clamp is arranged between clamp slots 33. In this way, atomizer end 71 of the hose is directed away from blower exhaust 61, so that as atomized liquid is expelled from hose 70, the atomized liquid is caught in and propelled by the air stream emanating from the blower exhaust 61.

(16) FIG. 4 is an illustration of an entire liquid atomizing and dispersal system comprising a blower attachment 10, clamped to a blower 60 at the blower exhaust pipe 61. A hose 70 is clipped into the blower attachment and extends to a pressurized tank 50 containing liquid to be atomized and spread, such tank held by the user. In other embodiments, either the blower, the tank or both could be embodied as a backpack, with a wheeled pull cart, or in other known styles for ease of use.
