Abstract

A garden hose spray gun for domestic or agricultural use comprising of a spray gun having a hose connection 9, water on/off valve 5, 6, 7, 8, 10, 11, 16 and a spray nozzle 3, with an added section of tubing in line with the spray, wherein the tubing is separated into two water chambers 12, 13 by a solid surface restrictor 4 which comprises of a concave dome at its centre, with a plurality of holes 14 around its circumference to facilitate the passage of water. The action of the restrictor will cause water in the first chamber to travel into the second chamber via the holes and significantly reduce the forward kinetic energy of the water without restricting flow rate at the source.

Description

DESCRIPTION

Invention titled: Continuous flow watering can No.2 The following statement is a full description of this invention, including the best method of performing it known to me.

Prior Art.

Conventional watering cans come in all shapes and sizes, but all have the same problem, that is that they only carry a limited amount of water, and when empty have to be taken to a water source, usually a tape to be refilled. They have the advantage of very low water pressure, and a large sprinkler rose, which is less likely to damage seedlings roots or bore into the potting mix or damage delicate plants or soils. The weight of a full watering can be a physical problem for persons not capable of lifting the weight. While a garden hose filled with an attachment water jet, sprinkler or sprayer does not have the problem of having to be refilled, it does have the problem of too much water pressure, which even with the various nozzle choices available, still has too much water pressure, and when watering seedlings, new plants or delicate plants and soils, can damage them, and their roots.

If the mist settiiig is used on the choice of nozzles, it will cover an area much larger than the area being watered, with the spray drifting in the breeze, wasting most of the water used. The Object of this invention is to provide a means to overcome the problems of needing to be refilled, eliminate the weight issue, and most importantly significantly reduce the water pressure at the sprinkler rose, giving the same advantage of a watering can, with the water saving advantages of only watering the area intended.

Description of this invention.

This invention in its simplest form consist of a conventional garden hose water jet, sprinkler or sprayer, with a stem of a handle 1, a handle 11, Valve stem 16, valve opening adjuster nut 10, a spring 8, hose connector 9, valve body 5, valve face 6 and valve stem face 7, with a round piece of water chamber'tubing 15, to form the primary water chamber 12 and secondary water chamber 13. The two chambers are separated by a restriction body 2, which has a solid surface restriction face 4 at its center, this surface may be any shape, flat, domed, or raised suitable for breaking up the incoming water jet from the valve face 6, and holes 14 between the edges of the solid surface restriction face 4 and the circumference of the restriction body 2. A sprinkler rose 3 is fixed to the end of the water chamber tubing 15. The operation is that the water enters the hose connection 9 and moves up the stein of the handle I through the valve body 5 in the primary water chamber 12. At this point it would be in a concentrated jet of water and hits the solid surface restriction face in the restriction body 2, the water would be separated into a 360 degrees spray and turned back in the direction of the valve body 5. This action would use a lot of the kinetic energy inherent in the jet of water, and the water would pool in the primary chamber 12, the incoming water would force the water to move from the primary chamber 12 through the holes 14 in the restriction body 2 into the secondary water chamber 13. This action would further reduce the kinetic energy in the water, and make it swell and be directionless, so by the time it reaches the sprinkler rose 3, it has lost most of the concentrated kinetic energy the water had as ajet, and would create back pressure on the water moving through the hose connection 9. The sprinkler rose 3 has a larger surface area than tile end area of the water chamber tubing 15, so the force of the water coming out of the sprinkler rose 3 would be similar to a watering can, relying on atmospheric pressure. In Fig. 1. it shows a schematic diagram, of a conventional garden hose jet, sprinkler or sprayer 1 filled with an intermediary water chamber 15 containing a restrictor body 2 with a conventional sprinkier rose 3, this thawing is not to scale, and the water chamber 15 may be a larger diameter. The water chamber shown is round, but can be square or any alternative cross section to suit design and performance requirements. Those skilled in the art would realize that the principle method of reducing the kinetic energy of the water described in the invention, would have application in any application requiring the reduction of water pressure.

Claims

Claims.What is claimed j: 1. A gardening sprinkler or spray gun suitable for domestic or agricultural use comprising: a conventional spray gun with a hose connection, water on / off valve, and spray nossel, wIth an added section of tubing in ne with the spray, with a shower rose at the opposite end to the incoming jet of water in the tube, the pIece of tubing s separated into two water chambers by a scUd. surface restrictor which consists of a concave dome section at its center, with holes around the circumference to aflow the water to escape through into the second chamber in the tube. The incoming jet: of water hits the center of the restrictor which resists and scatters th.e water back in the direction it came, t.he first chamber flils, and the water escapes into the second chamber through the holes at it circumference fiNing the second chamber with water and then the water, which has had the forward kinetic r energy significantly reduce without restricting. the flow rate from the source hose or r tubing, leaves the second chamber through the shower rose in a gentie low pressure spray similar to a watering can. If the shower rose is removed the water gently flows out of the end of the tube.
2. A gardening sprinkler or spray gun suitable for domestic or agricultural use comprising: a conventional spray gun with a hose connection, water on Ioff valve, and spray ncssel, with an added section of tubing in Une with the spray, with a shower rose at the opposite end to the incoming jet of water in the tube, so the incoming jet of water fills the tube with water and then the pool of water in the tube resists and scatters the jet of water. to significantly reduce the forward kinetic energy of the water in the incoming jet of water without restricting the flow rate from the source hose or tubing, and have the water leave the rose in a gentle ow pressure spray similar to a watering can.
3. The gardening sprinkler or spray of claim 2, were the section of tubing is long enough to have the forward kinetc energy of the water significantly reduce without restricting the flow rate from the source hose or tubing, or the outside diameter of the tubing. and the shower rose are arge enough to have the desired result

5. The gardening sprinkler or spray of claim 1. were the holes in the solid surface restrictor can be any shape, to sua design and performance required
