Description

Shower with water saving function {SHOWER TOOLS WITH WATER SAVING FUNCTION}

The present invention relates to a shower with a water-saving function is more specifically provided with a moving plate that is moved in accordance with the pressure of the fluid discharged through the head of the shower so that the fluid is injected only through the center at low water pressure and at high water pressure By allowing the fluid to be injected through the shower, a certain amount of fluid can be injected even with the fluid pressure change inside the shower, and a proper water pressure can be maintained by installing a valve that allows the inflow of external air and prevents the water pressure from dropping. When the fluid is mixed, soft fluid mixed with air is injected, but the shower is connected to a place where the water pressure is low, or even if the water pressure drops depending on the position of the shower, it prevents the fluid from flowing back to the outside, thereby preventing the internal water pressure from dropping. A shower is provided with a function.

In general, a shower is a sprinkler-shaped spray device for spraying cold or hot water, and is widely used for households such as toilets, sinks, and bathtubs, and for business purposes such as body showers, waterfalls, water softeners, and bathtubs.

It can be prevented. At this time, the above-mentioned shielding film 350 is preferably a synthetic resin film of a soft property.

Hereinafter will be described in detail the overall operating relationship of the shower (1) is added to the water saving function according to an embodiment of the present invention.

First, when the shower 1 having a water saving function is used at a low water pressure, when the fluid passing through the inlet 120 and the compression pipe 140 enters the discharge pipe 150, a vacuum may not be formed due to low water pressure. Air and fluid are discharged to the outside through the air inlet pipe 310 and the second air inlet hole (331). At this time, the internal air and the fluid discharged as the first air inlet 321 is closed by the shielding film 350 is no longer discharged and is blocked. Therefore, the fluid is normally discharged to the outlet 111 along the flow path 130, but due to low water pressure, the moving plate 230 cannot be pushed out, and passes through the first discharge hole 232 and the second discharge hole 222 in order. Is sprayed on.

In addition, when the shower 1 with the water saving function is used at a high water pressure, the fluid passing through the inlet 120 and the compression pipe 140 enters the discharge pipe 150, and the flow rate of the fluid is increased rapidly. As the internal pressure of 100 is lower than the external atmospheric pressure, a vacuum is formed, and a pressure difference is generated between the compression pipe 140 and the discharge pipe 150. At this time, the outside air is introduced into the inside through the air inlet pipe 310, the outside air passing through the first air inlet hole 321 of the first air inlet plate 320 while pushing the shielding film 350 inwards Passes through the second air inlet hole 331 of the second air inlet plate 330 and enters into the discharge pipe 150 along the air inlet pipe 310 and the fluid flowing into the discharge pipe 150 from the compression pipe 140 Are mixed.

When the fluid mixed with the outside air is discharged to the discharge port 111, the moving plate 230 is pushed toward the coupling member 210 due to the high water pressure, which causes some of the moving plate 230 to be removed. 1 is discharged to the outside through the discharge hole 232 and the second discharge hole 222 of the coupling member 210 and a portion between the stepped 112 and the guide protrusion 220 exposed as the moving plate 230 is moved. Passed through the discharge passage 221 formed in the injection through the third discharge hole 223 to the outside. Therefore, even at high water pressure, the fluid is properly divided into the center and the outside of the coupling member 210, and the external air is contained in the fluid, so that the fluid has a proper blowing force compared to the high water pressure and soft fluid to the bather. It can be provided.

It is to be understood by those skilled in the art that the present invention may be embodied in many other forms without departing from the spirit and scope of the invention, the embodiments being exemplarily described above. It is therefore intended that the above-described embodiments be considered as illustrative rather than restrictive, and that all implementations within the scope of the appended claims and their equivalents are intended to be included within the scope of the present invention.
