Description

[Detailed explanation of the invention] If the water hose connected to the water faucet is long, the water pressure will drop, making it impossible to obtain sufficient water spraying, washing, or cleaning effects, or the water may be pumped to a high place. However, there were many inconveniences such as the amount of water and water pressure becoming low, making work time-consuming.

Therefore, methods of pressurizing tap water externally have come to be used in household water sprinklers and water pumps, but conventional pressurized water sprinklers are not available to anyone due to electrical system safety regulations. It was not easy to put it into practical use, and the mechanism itself was complicated and inevitably expensive.

In view of these circumstances, the present invention relates to a simple water sprinkler developed with the aim of significantly simplifying the mechanism and eliminating the need for any consideration regarding the electrical system. The explanation will be divided into those with and without, based on the drawings.

Figures 1 to 6 show a first embodiment having a hose storage chamber, which is partitioned into three upper and lower chambers in the order of hose storage chamber 1, water storage tank 2, and pump chamber 3 from above. is forming.

The hose storage chamber 1 has a so-called box shape with an open top, and can store the water hose 4 rolled up.In order to prevent the stored water hose 4 from accidentally jumping out, the hose storage chamber 1 is shaped like a box with the top open. The flange 5 is formed by bending it.

6 is a union neck of a union joint attached to the bottom corner of the hose storage chamber 1. By turning and tightening the union joint nuts 1-7 of the union joint attached to the end of the water discharge hose 4, the water discharge 4 is connected to the union. It can be connected to and separated from the end of a second pipe body 8, which will be described later, via a joint.

9 is a spray nozzle attached to the tip of the water hose 4;
It goes without saying that you can select and use a nozzle with a shape and structure that suits your purpose, but at the connection between the water discharge hose 4 and the injection nozzle 9, you can quickly open and close the water passage by turning a conical plug with a handle. 10 easy-to-use cocks (stop valves)
is installed.

A water supply port 11 is provided in the earthen wall of the water storage tank 2 provided at the bottom of the hose storage room 1, and a discharge port 12 is provided in the bottom. A water use valve with a float (as shown) 13 is installed, and the valve body automatically adjusts the gap with the valve chamber in conjunction with the movement of the float 14, which moves in response to changes in the water level in the water storage tank 2. It is designed to open and close the water supply passage.

Although the drawing shows a general example in which the water tap 15 is a water faucet, it goes without saying that depending on the capacity and output of this water sprinkler, water can be taken from a location other than the faucet.

In addition, the water receiving hose 16 that connects the water tap 15 and the water supply port 11 of the water storage tank 2 can be adjusted depending on the location where this water sprinkler is used.
You can use a long or short hose as you like, but the water sprayer of this invention can be used with a hose 16 meters long or longer.
Also, the length of the water discharge hose 4 mentioned above may be, for example, one with an inner diameter of 12 m/m (general commercially available hose).
5 m or more can also be used.

A pump 18 is installed in a pump chamber 3 partitioned below the water storage tank 2, and a first pipe body 17 connected to the outlet 12 of the water storage tank 2 is connected to an inlet of the pump 18. The water in the water storage tank 2 is guided into the pump 18.

The second pipe body 8 is connected to the discharge port 18.

The second pipe body 8 penetrates the water storage tank 2 from below upwards and is guided to the bottom of the hose storage chamber 1.
The union screw 6 of the union joint described above is attached to the tip of the second pipe body 8, and is exposed at the bottom of the hose storage chamber 1.

Reference numeral 20 denotes a bypass branch pipe that connects the middle part of the pipe 8 and the bottom part 19 of the water storage tank 2. In the present invention, this bypass pipe 20 plays an extremely important role, and by providing this pipe 20, the mechanism can be significantly improved. I keep it simple.

In addition, a water control valve (not shown) is built into the bypass pipe branch 21 of the pipe 8, and when the pressure inside the pump discharge port side pipe 8 becomes higher than a predetermined pressure by closing the water stop valve 10, etc. The water control valve is opened and the water discharged from the pump 18 flows toward the bypass pipe 20 only at that time.

22 is a pressure tank of the pump 18, 23 is an analog display pressure gauge installed on the discharge port side of the pump 18, 24 is a drain cock of the pump 18, and 25 is a handle.

Next, the operation of the above embodiment will be explained.

Water receiving hose 16 connected to water faucet 15 during use
When the tap is connected to the water supply port 11 of the water storage tank 2 and the tap is opened, tap water passes through the water receiving hose 16 and reaches the water supply port 11. The water enters the water storage tank 2 through the water level control valve 13, and a portion of the water enters the pump 18 through the first pipe body 17 and serves as priming water.

When the water level in the water storage tank 2 reaches a predetermined level, the valve body of the water level control valve 13, which moves in conjunction with the movement of the float 14, cuts off the water supply passage.At this time, the power cord (not shown)
When the plug is inserted into a nearby outlet, the pump 18, which is already filled with priming water, is started at the same time, leading the water in the water storage tank 2 into the pump 18, pressurizing it in the pressure tank 22 of the pump 18, and discharging it. The water flowing and stored from the second pipe body 8 on the outlet side toward the water discharge hose 4 is discharged or sprayed from an injection nozzle 9 at a predetermined water pressure.

According to the experimental results using the Mitsubishi household pump CP-205G-I manufactured by Mitsubishi Electric Corporation as the pump 18, the water discharge hose 4 with an inner diameter of 12 m/m and a length of 15 m and a nozzle diameter of 4
When using the m/m injection nozzle 9, the water pressure is 1.7 kg.
/Cm2 of tap water, the pressure gauge 23 is 3°8 kg/cm"
It was found that the flight distance reached 14 m or more regardless of the length of the water receiving hose 16.

In this case, under normal conditions, the water level in the water storage tank 2 is maintained at about a half-hour level due to the continued replenishment of tap water.

When it is no longer necessary to spray or spray water, close the water stop valve 10 near the injection nozzle 9. However, when the water stop valve 10 is closed, the water pressure in the second pipe body 8 increases, so the bypass pipe branches off. A water use valve (not shown) provided in the section 21 is opened, and the pressurized water discharged from the pump 18 passes through the water control valve, passes through the bypass pipe 20, flows toward the water storage tank 2, and is discharged from the pump 18. Until the power is turned off, the water is circulated through the water storage tank 2, pump 18, and bypass pipe 20.

However, in the meantime, the water storage tank 2 is continuously replenished with tap water, so water is supplied to the water storage tank 2 until the water storage tank 2 is filled with water, and the water level control valve 1
When 3 is closed, the water supply will stop.

If the water sprinkling/discharging work is not to be continued, turn off the water stop valve 10.
While the water is closed, first turn off the power to the pump 18 and then close the water faucet, but if you wish to continue work, open the water stop valve 10 again. A similar task can be performed by

FIGS. 7 and 8 are cutaway views of the main parts of the second embodiment, which does not have a hose storage chamber, and the same reference numerals as in the first embodiment indicate the same members.

The second embodiment differs greatly from the first embodiment in that it does not have a hose storage chamber, and the end of the second pipe body 8 is directly led outside the machine, and the water discharge hose 4 is Similarly, it can be detachably connected to the section via a union joint.

Note that illustrations and explanations of both of the above embodiments have been omitted, but
In any case, it is a good idea to attach casters or wheels of an appropriate size to make it easier to move, and it is also a good idea to attach a push band to the back so that it can be easily moved anywhere like a handcart. Needless to say.

The present invention has been described above based on two embodiments, but the present invention includes a water storage tank 2 equipped with a water level control valve 13 that can be connected to an appropriate water faucet 15 such as a water faucet, and a discharge port as required. A water discharge hose 4 that can be removed from the second pipe body 8 on the side, a pump that pressurizes and discharges stored water toward the water discharge hose 4 ] 8, and water pressure in the second pipe body 8 on the pump discharge port side. The system is equipped with a bypass pipe 20 that allows water to flow toward the water storage tank 2 when the water reaches a predetermined pressure or higher, and a water stop valve 10 that can be operated near the water outlet of the water discharge hose 4. As is clear, if the water stop valve 10 at the end of the water hose is opened, pressurized water can be sprayed and discharged from the water tap 15 to a place far away, but when the water stop valve 10 is closed, the water tap 15 is closed. Even if 15 is left open, bypass pipe 2
0, the water circulates through the path of water storage tank 2 - pump 18 - bypass pipe 20 - water storage tank 2, and when the water storage tank 2 becomes full, the water level control valve 13 closes and the water supply can be stopped. Therefore, with the present invention, there is no need for the hassle of turning off the power to the pump or turning off the water faucet when interrupting work such as watering as in the past. It has the advantage of being able to be turned off by opening and closing the water stop valve 10 at hand, and compared to conventional water sprinklers and water pumps, the mechanism is significantly simpler, lighter and more compact, and the electrical system is much simpler. It does not require any wiring at all, and can be manufactured by attaching a commercially available small pump for home use, making it extremely effective in terms of safety, economy, and cost.

It goes without saying that the water sprayer of the present invention can be used for gun-like spray, mist spray, or granular spray by replacing the spray nozzle attached to the water hose and the water spray.
Spraying water for agricultural work, washing vehicles, sprinkling and cleaning halls, sprinkling and cleaning public facilities, sprinkling water on roads and grounds, sprinkling water on station buildings and platforms, sprinkling and cleaning cooking areas, extinguishing fires and wildfires and bonfires, and gardening. Spraying water, pumping water upstairs, and sending high-pressure water to isolated areas are only a few examples of its use, and the present invention can extremely easily supply high-pressure water to places far away from the faucet, so it has great practical value. big.
