Description

  The present invention relates to a water-saving device for faucets, and particularly provides a water-saving device that can be attached to an existing faucet without blocking water and produces a stable water-saving effect.

  In recent years, with the concentration of population in large cities and the modernization of lifestyles, the amount of water used in cities has been increasing. On the other hand, the depletion of water resources has progressed and water saving has become an urgent issue. For this reason, many water-saving tools have been proposed. In particular, with the global warming, the weather is changing rapidly, and the amount of water in the river is significantly reduced depending on the region.

From this point of view, it is desirable to promote the spread of faucet water-saving devices as much as possible, and there is a need for the development of a device that is as easy to install as possible and produces a stable water-saving effect. An example of such a technique is disclosed in Patent Document 1.

Moreover, the installation work can be performed while maintaining the supply of water from the other faucets without closing the main tap of the water supply.

  In addition, the water-saving device for faucets of the present invention is fixed and stable since the jar is sandwiched between the faucet body and the universal tube, and is not moved by the water flow. And since the diameter decreases toward the bottom, there is no turbulent flow in the water flow. There is nothing.

  Furthermore, since it is not composed of thin parts such as springs, and has an integral structure as a whole, it can be used for a long time even if the water quality is poor.

  The invention described in claim 1 of the present invention has a bottomed cylindrical shape, has a plurality of through holes on the side surface or the bottom surface, has a flange on the open end of the bottomed cylinder, and has a flange on the faucet free pipe. Since it is attached so as to be on the upstream side of the water flow, the installation work can be performed without stopping the supply of water, and it has an effect of saving water stably and inexpensively with a simple structure.

  Examples of the water-saving device for faucets of the present invention will be described in detail below with reference to the drawings. In FIG. 2, 1 is a faucet body, and the handle shaft 2 is screwed together. A handle 3 is attached to the upper end of the handle shaft 2 with a screw 4.

  A free pipe 5 is attached to the faucet body 1 by a fixing nut 6 so as to be rotatable. In addition, the flexible tube 5 is watertight with the faucet body 1 by a packing 6.

  In FIG. 1, reference numeral 7 denotes a water-saving device for faucets according to the first embodiment, which is made of a material that is resistant to corrosion and can secure strength. The faucet water-saving device 7 has a bottomed cylindrical shape having a bottom 8 at one end, and has a flange 9 at the other end.

  The side surface has a plurality of openings 10, and the amount of water passing through the faucet water-saving device 7 is determined by the opening area of the openings 10. Therefore, the opening area can be set according to the degree of water saving.

  The faucet water saving device 7 configured as described above is attached to the faucet body 1 by the following operation.
