Furthermore, cleaning effect can be improved by supersonic vibration generated in association with blowout of the fine air bubbles.

Description

Detailed Description of the Invention

By utilizing electrostatic induction, the present invention prevents water leakage from the air-mixing holes, mixes fine bubbles in the water flow, generates a secondary water flow, and does not impair the feeling of use. The bubble bursts to generate ultrasonic vibration and enhance the cleaning effect.

In order to avoid the danger of falling off due to metal plating peeling and excessive weight, the material and metal were changed to improve safety.

The conventional product requires a plurality of adapters for connection depending on the uneven direction of the screw thread, but it relates to the correspondence of the uneven direction of the screw thread by inverting and connecting the internal parts.

As a conventional water-saving device, the flow rate is forcibly throttled so that the water flow does not flow beyond a certain amount, so there is a problem of deterioration in the feeling of use due to a decrease in the body water pressure due to insufficient water amount and water leaking from the mouth mixed with air .

There was a problem that the metal plating covering the material of the conventional product was peeled off due to rusting, causing injuries during cleaning, and there was a problem of injury due to excessive weight drop because the material is metal.

In the conventional product, when connecting a water-saving device, it was possible to cope with the uneven direction of the screw thread only in one direction, and when it was not possible, there was a problem of using an adapter.

Problems to be solved by the invention

The present invention has been made in view of the above-described problems of the conventional products, and prevents leakage of water by using electrostatic induction and impairs the feeling of use by mixing minute air and generating a secondary water flow. It aims to improve the cleaning power by ultrasonic vibration.

In addition, POM is used as the material, and it has light weight, creep resistance in a wide temperature range, extremely excellent fatigue resistance, machining characteristics, and secondary workability. Stainless steel SUS304 is used for the metal covering the material. It is resistant to rust, has excellent ductility, strength, heat resistance, and low temperature toughness, and aims to improve safety.

An object of the present invention is to provide a water-saving device that can cope with the uneven direction of a screw thread by inverting and connecting internal parts.

Means and actions / effects for solving the problem

In order to solve the above problems, the present invention provides an electrostatic induction type electromagnetic valve in the air suction hole, and the electrons in the water when passing water are confused with plus and minus. The electromagnetic valve is open and allows gas fluid to enter due to the gas supply pressure. When water stops, the movement of water stops, electrostatic induction works on the electrostatic induction type electromagnetic valve carrying negative electrons, and the positive electrons in the water are attracted and closed to prevent liquid fluid and gas fluid from entering. It is.

According to this configuration, minute bubbles are generated by the supply pressures in the two fluids of the gas fluid that enter the liquid fluid from the air suction hole when the water is passed, so that significant water saving is possible. Further, since the flow velocity is increased by restricting the flow of fluid and the amount of water injection is increased by the inflow port and the rectifying hole, it is possible to save water without impairing the feeling of use while controlling the flow rate.

In the present invention, a POM containing no environmental hormone is used, which is excellent in durability and can be reduced in weight. In addition, SUS304, which does not rust easily, is used for the metal that covers POM, enabling a highly safe water-saving device.

In the present invention, in order to enable the connection by inverting the internal parts, when installing in the pipe or faucet body, the adapter was examined in the uneven direction of the connection thread, but in either the uneven direction Can be provided as attachable.

The present invention will be described below with reference to the drawings.

1 and 4 are cross-sectional views of the water-saving device main body 1, the internal part 2, and the electrostatic induction electromagnetic valve 7. Inside part 2, air suction hole 3 for supplying gas, inlet 4 for restricting liquid supply and restricting the flow of fluid, rectifying hole 5 for passing the restricted fluid, secondary water flow by mixing air A flow hole 6, a static induction type electromagnetic valve 7 that is a valve that opens and closes the supply of liquid fluid and gas fluid by electrostatic induction, a nozzle hole 8 that is designed to replace the water-saving device body, and the internal part 2, The contents from 2 to 11 are included in the female screw hole 9, the male screw hole 10, and the O-ring parts 11 and 1 which are the installation parts of the O-ring. In addition, the material of a water-saving instrument main body and internal parts is formed with POM.

In FIG. 1 of the said structure, when a user twists a faucet, it is sectional drawing of a water-saving device at the time of water flow (FIG. 2).

It is assumed that the direction of the liquid fluid flows in the direction of the arrow, and the liquid fluid enters the water-saving device body and discharges water from each faucet or shower via the internal parts. When the liquid fluid enters the internal part from the female screw hole 9 of the water-saving device body, the flowing water whose flow rate is increased by restricting the flow of the fluid through the flow inlet 4 that restricts the liquid supply passes through the rectifying hole 5, It is ejected at once through the flow hole 6 and discharged from the male screw hole 10 to a faucet or a pipe.

Since positive and negative electrons in the water are scattered and flowing during water flow, the electrostatic induction type electromagnetic valve 7 bearing negative electrons allows gas supply by the gas supply pressure, and the internal parts from the air suction hole 3 Air is mixed into 2 and two pressures of gas supply and liquid supply are applied to produce minute bubbles. Fine bubbles are added to the fluid to be ejected, and the water flow is discharged with high momentum through the male screw hole 10.

When the direction of the liquid fluid is reversed, the internal parts are reversed and mounted, so that the configuration is as shown in FIG.

At the time of water stoppage (FIG. 3), the flow of water disappears, so electrostatic induction works on the electrostatic induction type electromagnetic valve 7 carrying negative electrons, and the positive electrons in the water are attracted and closed, and the liquid fluid and Since the intrusion of the gas fluid is not permitted, the air suction hole 3 can be used without water leakage.

Further, the static induction type electromagnetic valve 7 is also designed as a check valve, and since the liquid and gas supply pressure at the time of water stop does not work, there is no water discharge from the static induction type electromagnetic valve 7.

As shown in FIGS. 1 and 4, the air suction hole 3 is in an engaged state in which the water-saving device body 1 is provided in the internal part 2, and the positions of the air suction holes 3 in the water-saving device body 1 and the internal part 2 do not change. .

4 is a cross-sectional view of the water-saving device main body 1, the internal part 2, and the electrostatic induction electromagnetic valve 7 with the internal parts of FIG. 1 inverted. Even when the order of the female screw and the male screw is determined, the internal part 2 of the water saving device is reversed and mounted in accordance with the direction of the liquid fluid to be passed, and can be handled without depending on the direction of the liquid fluid. The nozzle hole 8 is designed so that the internal part 2 can be reversed and mounted.
