A shower nozzle using a venturi structure according to the present invention is a shower nozzle using a venturi structure which is fastened between a shower hose 300 and a shower head 200. The shower nozzle 100 has a hollow body A venturi bolt 110 having a venturi structure in which a nut is formed on the outer periphery of both ends and a cover nut 120 having a screw thread formed on the inner periphery so as to be screwed to the outlet side of the venturi bolt 110 .

The venturi bolt 110 is formed such that the inner and outer diameters of the inflow part 111 side where the fluid flows into the inside are formed to be large and the inner and outer diameters of the outflow part 113 side to which the fluid flows out are made small A step 117 is formed on the outer periphery of the middle portion of the nozzle and a slope is formed in the inner periphery of the nozzle so as to gradually increase in thickness from the inflow portion 111 toward the middle portion so that the thickness becomes gradually thinner toward the outflow portion 113 And a pair of air holes 114 are formed so as to be symmetrical with respect to each other from the center so that air flows into the outer periphery of the outer periphery where the step 117 is formed.

Further, the cover nut 120 is characterized in that the threaded surface is formed on the inner peripheral edge of the outflow portion 113 side where the fluid is discharged so as to be screwed to the shower head 200.

The outer periphery of the venturi bolt 110 in which the air hole 114 is formed is formed as a flat surface.

Further, the outflow portion 113 of the venturi bolt 110 is formed to extend further than the screw surface formed on the outer circumferential edge.

The stopper 122 is protruded along the inner periphery of the cover nut 120 so as to contact the step 117 of the venturi bolt 110 when the venturi bolt 110 is screwed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

The shower nozzle using the venturi structure of the present invention is composed of a venturi bolt 110 made using the venturi principle and a cover nut 120 surrounding the venturi bolt 110.

FIG. 1 is a perspective view of a shower incorporating a shower nozzle using a venturi structure according to the present invention, and FIG. 2 is a perspective view illustrating a shower nozzle using a venturi structure according to the present invention in a shower head and a hose.

1 and 2, the shower nozzle 100 is coupled between the shower head 200 and the hose 300 so that the water flowing in the hose passes through the shower nozzle 100 of the venturi structure, ).

3 is a vertical sectional view of a shower nozzle using the venturi structure of the present invention.

3, the venturi bolt 110 and the cover nut 120 are bolt-nut connected. In the venturi bolt 110, a portion where the fluid flows is thick and a tube is thick. It is a venturi structure in which the tube width is gradually increased again.

That is, the venturi structure increases the velocity of the flow as it passes through where the air is compressed, according to the theory that the product of velocity and area is constant.

The smaller the diameter of the pipe through which the fluid passes, the faster the speed of the fluid, the lower the pressure, the faster the velocity of the fluid at the thinnest part of the pipe, and the lowest pressure.

In addition, when the hole is pierced through the hole of the smallest tube by the above-described principle, external air is most actively introduced to maximize the synergy effect that the fluid flowing in the tube reaches the outside air and further increases the flow rate.

Accordingly, the water supplied from the hose flows into the inner pipe of the nozzle through the inlet portion 111, passes through the pipe whose width gradually narrows, and then flows out through the pipe center portion 112 having the narrowest width, ).

At this time, the intensity of the water exiting through the outlet 113 is much stronger than the intensity of the water entering the inlet 111, and flows into the shower head.

According to the venturi theory, a pair of air holes are formed at the center of the tube 112 having the fastest water flow velocity so as to be symmetrical with respect to each other from the center, thereby further increasing the flow rate of water.

In addition, since the amount of water flowing through the nozzle tube gradually becomes narrower at the tube center portion 112, the amount of water flowing out to the outlet portion 113 is smaller than the amount of water entering the inlet portion 111 As this water-saving effect is brought out, the flow rate of the water becomes greater, and the strength of the water coming out of the shower head becomes stronger.

The cover nut 120 is connected to the venturi bolt 110 by a bolt nut so that the venturi bolt 110 and the shower head are bolted to each other to fix the vent hole 114. When the user uses a shower Thereby preventing the air hole 114 from being closed by hand.

That is, the outer periphery of the venturi bolt 110 in which the air hole 114 is formed is formed as a flat surface.

A space is formed between the plane where the air hole 114 is formed and the inner periphery of the cover nut 120 and the air hole 114 is located inside the cover nut 120, The air hole 114 is not blocked.

At this time, the air coming in from the outside through the space between the venturi bolt 110 and the cover nut 120 is dispersed to the inside of the cover nut 120 and spread smoothly to the inside of the nozzle through the air hole 114 without spreading There is a stopper 122 for allowing the gas to flow.

The stopper 122 is in close contact with the step 117 to allow external air to flow into the air hole 114.

4 is a perspective view of a venturi bolt and a cover nut of a shower nozzle using an inventive venturi structure.

As shown in FIG. 4, the hose and the bolt-nut are connected to each other through the hose coupling part 115 of the benzene rebolt 110, and the water flowing out of the hose passes through the pipe 116 of the venturi bolt and is transferred to the shower head.

That is, in this process, the water saving and the water strength of the shower are increased.

The periphery of the air hole 114 through which the outside air is introduced is flat so that the air hole 114 can be prevented from being clogged by the cover nut when the cover nut 120 is coupled.

At the end of the cover nut 120, an engaging portion 121 capable of engaging with the shower head 200 and a bolt nut is positioned.

FIG. 5 is a perspective view of a shower nozzle using a venturi structure according to the present invention, and is coupled between a shower head and a hose as shown in FIG.

Accordingly, the shower nozzle using the venturi structure of the present invention can reduce the thickness of the pipe through which the water passes, thereby achieving a water saving effect. At the same time, the venturi principle speeds up the water flow rate and decreases the pressure.
