Abstract

PROBLEM TO BE SOLVED: To provide an automatic water sprinkling device having a simple constitution and also at a low cost. SOLUTION: This automatic water sprinkling device is constituted by connecting a charging port 7 with a tap 6 and constituting a discharging port 9 with a float 2 and a valve 3 for opening and closing the discharging port 9 connected to a hose 8 in a tank 1. In this case, the device is constituted by linking the valve 3 and the float 2 with a string body 10, generating a floating power of a float when a prescribed amount of water accumulates and a water level attains at a certain level, opening the discharging port 9 by the action of the float so as to bring up the valve 3 blocking the port 9 through a string body 10, and also blocking the discharging port 9 with the valve 3 having a lighter specific gravity than water by own weight thereof, when the water level becomes approximately at the lower surface of the tank 1.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a tank in which an inlet is connected to a faucet and an outlet formed on a lower surface is connected to a hose. A valve for opening and closing the outlet is housed, and the valve and the float are connected by a string, and when the float reaches a predetermined level when a predetermined amount of water is accumulated in the tank. A buoyancy is generated, the valve closing the outlet is lifted through the string-like body and the outlet is opened, and the specific gravity of the valve is lower than that of water, and the water level is almost at the level of the lower surface of the tank. When the outlet is closed by its own weight, the valve is provided with a guide rod inserted into the outlet, and a valve is provided in the tank so that the lower end of the guide rod does not come off from the outlet. Provide a stopper to stop the rise due to buoyancy It is preferred.

According to the above configuration of the present invention, when the water flowing into the tank from the inflow port accumulates and reaches a predetermined amount,
The float becomes buoyant, causing the valve to open the outlet and a predetermined amount of water to be sprinkled from the hose. The valve closes the outlet when the water level is almost at the level of the lower surface of the tank, so that water starts to collect in the tank again, and the above-described operation is repeated. Therefore, a predetermined amount of water is sprinkled intermittently.

The tank 1 has a step portion 4 formed at a place where a predetermined amount of water is stored.
An inflow port 7 connected to a faucet 6 via a through hole is formed, and an outflow port 9 to which a hose 8 is connected is formed on the lower surface. A float 2 composed of, for example, a hollow resin molded product, a foamed resin molded product, or the like is placed on a step portion 4 inside the tank 1, and an upper end of a string-like body, for example, a chain 10 is connected to a lower surface thereof. The valve 3 is connected to the lower end.

The float 2 has a projection 11 on its lower surface, and water flowing from the faucet 6 through the flow control cock 5 through the inflow port 7 while being placed on the step 4 allows the water to flow into the step 4 and the float 2. Is stored in the tank 1 through the gap 12. The chain 10 has a length such that the valve 3 closes the outlet 9 with the float 2 resting on the step 4. The valve 3 has a specific gravity lighter than that of water and is made of, for example, rubber. The guide rod 13 provided at the lower part of the valve 3 and the stopper 14 provided at the intermediate part of the tank 1 are closed by the buoyancy of the valve 3 without falling off the outlet 9 when the valve 3 is lowered again. When the valve 3 floated by buoyancy engages with the stopper 14, the guide rod 13 in the outlet 9 does not escape from the outlet 9.

The water from the water pipe passes through the faucet 6 through the flow control cock 5 and flows into the tank 1 from the inflow port 7 at a constant flow rate.
If the tank 1 flows at a flow rate at which the tank 1 becomes full in 24 hours, since the valve 3 is closed due to its weight and the water pressure applied to the upper part, water starts to accumulate, and after 24 hours, the water level rises above the step portion 4. Reaches and becomes full. Float 2
Since it is designed to have a buoyancy greater than the sum of its own weight, the weight of the valve 3 and the pressure head applied to the valve 3, the valve 3 begins to float and rises, opening the outlet 9. Therefore, the water in the tank 1 starts discharging from the outlet 9 through the hose 8. Once the valve 3 is pulled by the float 2 via the chain 10 and rises, the valve 3 then rises to the position of the stopper 14 by buoyancy. When the water level decreases due to a decrease in the water level, the valve 3 also moves downward.
