Water saving device

Abstract

A water saving device having an installation cover (2) for installation on a faucet (1) etc., a water saving piece (6) installed within the installation cover (2) and having one or more water discharge holes (62), and a water-tight packing (3) for preventing water leakage from between the faucet (1) etc. and the installation cover (2). A pressure reduction piece (4) is placed between the installation cover (2) and the water saving piece (6), and the pressure reduction piece (4) has a flow path change hole (42) for forcibly changing the direction of water supplied from water discharge means, such as the faucet (1) etc., to reduce the pressure of the water.

Description

technical field [0001] The present invention relates to a water-saving device. The water-saving device is installed on a faucet (hereinafter simply referred to as a "faucet") that discharges water such as a rotary faucet, a mixing faucet, or an automatic faucet. And the body discharges water that is soft to the touch. Background technique [0002] In the past, there are known water-saving appliances that can save water by suppressing the discharge of water without changing the usability of the water supply cock. For example, the following water-saving appliances have been proposed as the above-mentioned water-saving appliances. The installation cover of the faucet and the like and the watertight gasket used to prevent water leakage between the above-mentioned faucet and the installation cover, and a cylindrical water-saving component (such as Refer to Patent Document 1).

AI Technical Summary

Problems solved by technology

[0005] However, on the other hand, the water supply tap can be used to suppress the water discharged from the water passage hole of the above-mentioned water-saving component to save water, but the adjustment of the water supply valve is delicate and difficult to operate, and the water potential (water pressure) of the discharged water is relatively low. Strong, so there are disadvantages such as splashing of water after touching the user's skin to pollute the surrounding environment, or soaking the cuffs of clothes

In addition, for users with soft skin such as infants or women, there is a problem that the water with strong water potential stimulates the skin too much.

[0006] Of course, in order to suppress the water potential (water pressure) of the water, it is only necessary to operate the water stopcock. However, in this operation, the water stopcock is fully opened during the water supply restriction period, and the water stopcock is tightened outside the period. trouble

In addition, in this case, the original purpose, function, and effect of saving water by suppressing the discharge of the faucet without changing the usability of the water supply cock described above cannot be obtained.

[0007] Further, depending on various conditions such as geographic location conditions or floors of buildings, etc., or water supply conditions, the amount of water and water pressure sprayed from faucets, etc. are not constant, and water is not sprayed with a constant amount or constant pressure, so it is difficult to Make the water discharged from the water hole of the water saving part a constant amount or constant pressure
