This will be described in more detail below for each configuration.

The nozzle tip body 100 is connected to an end of a nozzle 20 constituting a nozzle portion of a bidet and is supplied with a fluid (cleansing water, enema water) through the nozzle 20, A fluid supply passage 120, and a plurality of first protrusions 130 and 140.

Here, the case 110 forms an outer appearance of the nozzle tip body 100, and has a space in which air is stored, and an upper end is formed of a cylinder having an open structure. A circumferential wall 112 forming a circumference and a rear wall 113 joined to the nozzle 20 while forming a rear side. At this time, the rear surface of the rear wall 113 is formed as a recessed structure so that the end of the nozzle 20 is accommodated while being coupled thereto.

Particularly, in the embodiment of the present invention, the overall structure of the case 110 constituting the nozzle tip body 100 is a cylindrical structure, but the present invention is not limited thereto.

The fluid supply passage portion 120 is a portion for guiding the supply flow of the fluid.

The fluid supply passage 120 is formed in the bottom space of the case 110, and a plurality of horizontal holes 121 and 122 for supplying fluid are respectively formed in the fluid supply passage 120.

Each of the horizontal holes 121 and 122 includes a horizontal hole 121 for supplying a washing water to a genital part of a user and a drain hole 121 for supplying a fluid to the user's anus, And a horizontal hole 122. At this time, the two horizontal holes 121 and 122 are vertically spaced from each other, and the cleansing water supplying horizontal hole 121 is formed to be located on the upper side relative to the enema supply water horizontal hole 122, The length of the horizontal hole 121 for supplying the cleansing water is formed to be shorter than the length of the horizontal hole 122 for supplying the enema water.

In addition, the fluid inlet side of the cleansing water supplying horizontal hole 121 and the enema supply water supplying horizontal hole 122 is formed to penetrate the rear wall 113 constituting the case 110, (Cleansing water and enema number) separated from the nozzle 20 of the bidet through the through holes of the horizontal holes 121 and 122 of the bidet.

In addition, in the embodiment of the present invention, as shown in FIGS. 4 and 5, the inner end portions of the horizontal holes 121 and 122 are formed to be gradually inclined downward toward the ends thereof. This structure will be described again in the description of the guide holes 131 and 141 of the first projecting extensions 130 and 140, which will be described later.

The first projecting extensions 130 and 140 guide the fluid (cleansing water and enema water) flowing through the horizontal holes 121 and 122 to flow upward.

Each of the first projecting extensions 130 and 140 protrudes upward from the upper surface of the fluid supply passage 120. In the embodiment of the present invention, A first protrusion extension part 130 for supplying cleaning water for guiding the fluid flow in the horizontal hole 121 for supplying water to the first hole 130 for guiding the fluid in the horizontal hole 122 for supplying water, And the protruding extension part 140. In this case, the first protruding extension parts 130 and 140 are spaced apart from each other.

Particularly, it is preferable that the guide holes 131 and 141 are formed so as to communicate with an inner end portion formed obliquely in the upper surface of each of the horizontal holes 121 and 122.

The communication structure between the guide holes 131 and 141 and the horizontal holes 121 and 122 allows the flow of the fluid to be maximized smoothly while considering workability for injection molding of the nozzle tip body 100. That is, it is most preferable in the flow of the fluid to form a rounded connection portion between the guide holes 131 and 141 and the horizontal holes 121 and 122, but it is practically impossible to form grooves of such a structure by injection molding In consideration of the above-mentioned inclined structure, injection molding is possible but the flow of the fluid can be made as smooth as possible.

Although not shown, the guide holes 131 and 141 do not directly communicate with the inclined portions of the horizontal holes 121 and 122 but communicate with each other in the vicinity of the inclined portion. However, due to the structural characteristics of the inclined portion, The fluid can be supplied smoothly.

First air storage grooves 132 and 142 are formed on the upper surfaces of the first protrusions 130 and 140 along the circumference of the guide holes 131 and 141, Air communication holes 133 and 143 for communicating the space in the case 110 and the first air storage grooves 132 and 142 are formed on the circumferential surface, respectively.

Next, the nozzle tip cap 200 closes the open upper side of the nozzle tip body 100 from the external environment and injects the fluid supplied to the nozzle tip body 100, And the nozzle tip body 100 is fixed by welding.

The nozzle tip cap 200 includes a cap body 210 and a plurality of second protruding extensions 220 and 230.

The cap body 210 covers the open upper end of the case 110 forming the nozzle tip body 100 and has a plurality of exhaust holes 211 and 212 formed on the upper surface thereof. Each of the discharge holes 211 and 212 is divided into a washing water discharge hole 211 for spraying the fluid to the genital area of the user and an enema water discharging hole 212 for spraying the fluid to the anal region of the user, Each of the exhaust holes 211 and 212 is provided not only as a portion for injecting the fluid as described above, but also serves to supply outside air into the case 110 of the nozzle tip body 100.

In particular, at least some of the contact areas between the nozzle tip body 100 and the nozzle tip cap 200 may be formed to have concave-convex structures corresponding to each other. This is to enable the nozzle tip cap 200 to be in a correct position in the process of ultrasonic welding the nozzle tip cap 200 to the nozzle tip body 100.

For this, in the embodiment of the present invention, a guide protrusion 114 is formed inwardly on the inner surface of the front wall 111 and the inner surface of the rear wall 113 of the case 110 constituting the nozzle tip body 100, The cap body 210 constituting the tip cap 200 is formed with recesses 214 in which the guide protrusions 114 are received. Although it is not shown in the drawing, a receiving groove is formed in the inner surface of the front wall 111 and the inner surface of the rear wall 113 of the case 110 forming the nozzle tip body 100, A guide protrusion may be formed at both ends of the cap body 210. In an exemplary embodiment, a second protrusion extension 230 of each of the second protrusion extensions 220 and 230, described later, A groove 214 may be formed.

The second protruding portions 230 and 240 guide the discharge flow of the fluid to the discharge holes 211 and 212 formed in the cap body 210.

Each of the second protruding extensions 230 and 240 protrudes downward from the bottom surface of the cap main body 210 where the discharge holes 211 and 212 are formed and the cleaning water supply agent A second protruding extension portion 230 for supplying cleaning water to the first protruding extension portion 130 and a first protruding extension portion 140 for supplying the enriched aqueous solution constituting the nozzle tip body 100, And a second protruding extension portion 240 for supply.

At this time, the fluid that has passed through the guide holes 131 and 141 formed in the first protrusions 130 and 140 is introduced into the second protrusions 230 and 240 to be guided to the discharge holes 211 and 212 And injection holes 231 and 241 are formed through the through holes, respectively.

Particularly, the guide holes 131 and 141 formed in the first protruding extensions 130 and 140 of the nozzle tip body 100 and the second protruding extensions 230 and 240 of the nozzle tip cap 200, respectively, (231, 241) are formed vertically or inclined from the respective horizontal holes (121, 1220) according to the injection position of the fluid.

Second air storage grooves 232 and 242 corresponding to the first air storage grooves 132 and 142 are formed on the bottom surfaces of the second protruding extensions 230 and 240, respectively. The second air storage grooves 232 and 242 together with the first air storage grooves 132 and 142 form a space in which air to be mixed into the fluid is temporarily stored.

That is, by the structure of the first air storage grooves 132 and 142 and the second air storage grooves 232 and 242, the fluid that flows through the guide holes 131 and 141 and flows into the injection holes 231 and 241 The air in each of the air storage grooves 132, 142, 232, and 242 is mixed into the air, so that the impact due to the impact of the fluid can be mitigated by the air mixed in the fluid. At this time, when the air in the respective air storage grooves 132, 142, 232, and 242 is short of air in the case 110 due to the air communication holes 133 and 143 of the first protrusions 130 and 140 formed with the first air storage grooves 132 and 142 The air can be forcedly sucked into the air storage grooves 132, 142, 232 and 242 through the air communication holes 133 and 143 so that only a proper amount of air can always be mixed with the fluid. As a result, the fluid injection pressure The pain felt by the user can be minimized (or solved) by the impact caused by the impact of the fluid.

6 and 7, the upper surface side portions of the first protrusion extending portions 130 and 140 and the lower surface side surrounding portions of the second protrusion extending portions 230 and 240 are in a state And the fluid of the injection holes 231 and 241 formed in the respective second protruding extensions 230 and 240 and the fluid in the fluid outlet side of the guide holes 131 and 141 formed in the first protruding extensions 130 and 140, It is preferable that the portions where the inflow side is located are formed to be spaced apart from each other.

That is, through the provision of the spaced apart portions, the air existing in each of the air storage grooves 132, 142, 232, and 242 can be smoothly mixed into the fluid passing through the guide holes 131 and 141 and into the injection holes 231 and 241, Each of the air storage grooves 132, 142, 232 and 242 is sealed from the outside except for the air communication holes 133 and 143 by the close contact between the first protruding extensions 130 and 140 and the second protruding extensions 230 and 240 . Accordingly, the air supplied into each of the air storage grooves 132, 142, 232, and 242 is not forcedly supplied from the outside but is sucked into the air storage grooves 132, 142, 232, and 242 by the pressure of the fluid, . ≪ / RTI >

In the following, the operation of the nozzle tip assembly 10 for a bidet according to an embodiment of the present invention described above will be described in detail by the user to explain the operation of the nozzle tip assembly 10 in selecting the enema mode.

First, when an operation (for example, selection of enema mode) is performed on a control unit (not shown) of the bidet according to the user's needs, the duct 22 for supplying enema water of the nozzle 20 A high-pressure fluid (enema water) is supplied.

When the fluid is supplied, the fluid passes through the rear wall 113 of the case 110 constituting the nozzle tip body 100 and flows into the horizontal hole And then flows into the guide hole 141 in the first protruding extension portion 140 for supplying the enema supply which communicates with the upper surface of the front end of the enema supply water horizontal hole 122.

In this case, considering that the upper surface of the end of the enema supply water horizontal hole 122 is formed to be gradually downwardly inclined, fluid flowing into the enema water supply horizontal hole 122 is formed to communicate with the inclined portion So that it can smoothly flow into the guide hole 141.

As described above, the fluid that flows upward in the guide hole 141 flows into the gap between the opposed surfaces between the first protruding extension portion 140 for supplying the enema supply water and the second protruding extension portion 240 for enema supply, And then flows into the spray hole 241 formed in the second projecting extension 240 for supplying the enema water.

Thereafter, the fluid is guided upward through the spray hole 241 and then sprayed upward through the shower water outlet hole 212 formed in the cap body 210 of the nozzle tip cap 200, I will preside.

At this time, the fluid passes through the guide hole 141 and flows into the injection hole 241. The first protruding extension part 140 and the second protruding extension part 240 for supplying the enema water supply water, The air in each of the air storage grooves 142, 242 communicating with the spaced-apart portions between the opposing faces of the interspace is introduced into the fluid by the pressure resulting from the flow of the fluid, whereby the fluid has minute bubbles. In particular, since air is not forcedly supplied into each of the air storage grooves 142 and 242, but air in the case 110 is sucked through the air communication hole 143 due to a pressure difference, The phenomenon that is large or insufficient can be prevented.

Accordingly, even if the fluid hits the skin of the user while cleaning the perineum of the user, the generation of pain of the user can be minimized by the influence of the minute bubbles mixed in the fluid.

When the set time has elapsed continuously and repeatedly in each of the above steps, the operation of the control unit is controlled, and the supply of the fluid from the nozzle 20 is stopped, thereby ending the enema mode.

When the operation of the control unit of the bidet according to the user's needs is not the enema mode but the cleaning mode or the complex mode as described above, the fluid into the channels 21 and 22 for supplying the fluid to the nozzle 20 The supply of the fluid into the horizontal holes 121 and 122 of the fluid supply passage 120 is performed differently.

That is, when the user selects the cleaning mode, the fluid is supplied through the channel 21 for supplying the cleaning water of the nozzle 20, and the fluid thus supplied is supplied to the cleaning water supply hole 121 through the communication hole 121 The washing water is sprayed through the washing water discharging hole 211 after passing through the guide hole 131 and the spray hole 231 communicating with the guide hole 131. In this case, Mode is selected, the fluid is supplied through both the channel 21 for supplying the washing water of the nozzle 20 and the channel 22 for supplying the enema water, and the fluid thus supplied is supplied to the horizontal holes 121 and the enema water supply horizontal hole 122 and the guide holes 131 and 141 communicated with the guide holes 131 and 141 and the injection holes 231 and 241 communicated with the guide holes 131 and 141, And an enema water discharge hole 212, Section will perform the operation.

Of course, in the process described above, the fluid is mixed with the air existing in each of the air storage grooves 132, 142, 232, and 242 during the passage between the first protruding extensions 130 and 140 and the second protruding extensions 230 and 240, The pain felt by the user due to the hydraulic pressure of the fluid can be minimized.

As a result, the bidet nozzle tip assembly 10 according to the present invention can prevent air from being introduced into the fluid in the process of injecting the fluid, thereby preventing the user from causing pain due to excessive water pressure.

In particular, each of the air storage grooves 132, 142, 232, and 242 for introducing air into the fluid may include first protruding extensions 130 and 140 of the nozzle tip body 100 and second protruding extensions 230 and 240 of the nozzle tip cap 200 The air storage grooves 132, 142, 232, and 242 are formed to be in communication with the space in the case 110 so that air is not forcedly supplied into the air storage grooves 132, 142, 232, and 242, The air in the case 110 can be sucked in due to the difference in pressure through the openings 133 and 143 so that the excessive amount or insufficient amount of air mixed in the fluid can be prevented.

In addition, even if the fluid is injected at a plurality of positions, the structure for introducing air into each of the air storage grooves 132, 142, 232, and 242 for introducing air into the fluid is as simple as possible, The increase in the size can be prevented.
