[0001] Spray head for a sink [

The present invention relates to a spray head for a sink, and more particularly, to a spray head for sink, more particularly, to simplify the structure of the spray head by distinguishing between the direct water and the spray water by pushing only one point, In particular, the present invention relates to a spray head for a sink capable of significantly improving the convenience of use because it can mix direct water or spray water in half by efficient structure.

There is a faucet on one side of the sink, which is a place to do dishes or wash food. In recent years, a spray head is detachably coupled to the spray head to improve the convenience of use.

The spray head has a shape similar to that of a shower head in a bathroom, and has a water outlet divided into a direct portion and a spray portion.

On one side of the spray head, a left / right switching button is mounted as a switching function of water jetting type.

Accordingly, when the user operates the left / right switch button, for example, to the left, the direct water can be jetted through the water jetting port of the spray head, and when operated to the right side, the spray jet can be jetted through the jet port of the spray head.

Meanwhile, in the conventional spray head, the left and right changeover button is mostly installed for the change of the direct water and the spray number. However, since the different positions of the left and right sides are operated as described above, This may be somewhat uncomfortable.

In particular, conventional spray heads are somewhat inconvenient to use direct water and spray water at the same time. That is, in order to spray the direct water and the spray water halfway through the previous spray head, the left and right sides of the left and right changeover buttons must be operated at the same time by 50%, which may be considerably inconvenient for the user.

In actual use, water may be splashed by water pressure. In the case of spray water, water may be somewhat weak. Therefore, the number of running water or spray water may be mixed It is known that the former spray head has a structure that is somewhat inconvenient to mix a direct water or a half of the spray water. Therefore, there is a need for a new concept of a spray head for a sink which is different from the conventional one do.

The pushbutton 120, the jet body 130, and the button valve assembly 140 are mounted on the front portion of the head body 110. The rear portion of the head body 110 has a long bar structure It accomplishes.

The push button 120 is a kind of tact type button which is partially exposed on one side of the head body 110. As shown in FIG. 2, the head body 110 is partly exposed and pressurized once to press it toward the head body 110 as shown in FIG. At this time, the push button 120 is structurally depressed as shown in FIG.

The push button 120 is pressed between the push button 120 and the button valve assembly 140, that is, between the push button 120 and the head block 161 of the button valve assembly 140, And a button spring 115 elastically pressing the push button 120 to be returned to the home position is interposed. The button spring 115 can be applied as a leaf spring.

The jetting body 130 is a structure that is coupled to one side of the head body 110. The flood body 130 is provided with a water type floodgate 131 for guiding the direct water to be floated by the action of the button valve assembly 140 and a spray water floodgate 132 for guiding the water spray.

2, the water jetting spout 131 can be disposed at the center of the jetting body 130, and the spray water spouting port 132 has a circumferential direction at a radially outer side of the water jetting spout 131 .

The button valve assembly 140, together with the push button 120, is a key component of the spray head 100 for a sink according to the present embodiment.

The button valve assembly 140 is provided in the head body 110 and is connected to the push button 120. The push button 120 is directly driven (Fig. 13 (b)), the spray number (Fig. 13 (c)), and the mixed number of the direct water and the half number of spray water (Fig. 13 (d)).

The button valve assembly 140 is provided with a valve body 150, a head block 161, a tail cap 163, a pressing force transmission shaft 165, a flow path switching unit 170, a unit guide shaft 167, And a unit spring 169.

6 to 9, a half-moon shaped direct water inflow channel 151 and a half-moon shaped spray water inflow channel 152 symmetrically arranged with the direct water inflow channel 151 are formed on the side of the valve body 150, .

A direct water discharge passage 154 communicating with the direct water inflow passage 151 and discharging the direct water to the direct water discharge hole 131 of the jet body 130 is formed in the protruding portion 153 formed in the lower portion of the valve body 150. And a spray water discharge passage 155 communicating with the spray water inflow passage 152 and discharging the spray water to the spray water spout 132 of the jet body 130 is formed.

The head block 161 is connected to one side of the valve body 150. The head block 161 serves to shield one side of the direct water inflow passage 151 and the spray water inflow passage 152.

The tail cap 163 is a structure that is coupled to the other side of the valve body 150 while forming a spacing space S between the tail cap 163 and the valve body 150.

The spacing space S between the valve body 150 and the tail cap 163 provides a space in which the flow path switching unit 170 can be operated while the flow path switching unit 170 is disposed.

The tail cap 163 is formed with a water supply port 163a for supplying the water to the direct water inflow passage 151 of the valve body 150 and the spray water inflow passage 152 via the passage switching unit 170 do.

One end of the pressing force transmission shaft 165 is connected to the push button 120 through the head block 161 and the other area is movably disposed in the valve body 150. The pushing force of the push button 120 is switched Unit 170, as shown in FIG.

A double O-ring 165a is provided outside the pressing force transmitting shaft 165, that is, between the valve body 150 and the pressing force transmitting shaft 165.

The double O-ring 165a seals between the valve body 150 and the pressing force transmission shaft 165 to improve durability. A spacer 165b is interposed between the double O-ring 165a to prevent back-up of the double O-ring 165a.

On the other hand, the flow path switching unit 170 is arranged in the spacing space S and is rotated step by step at intervals of 90 degrees when the pressing force transmission shaft 165 is pressed.

The flow path switching unit 170 has a smaller size than the direct water inflow passage 151 and the spray water inflow passage 152 and is selectively in communication with the direct water inflow passage 151 and the spray water inflow passage 152, 151 and the spray water inflow passage 152 while switching the flow passage.

10 to 12, the flow path switching unit 170 includes a flow path switching plate 171 in which a plurality of flow path switching through holes 172 are formed, a flow path switching plate 171 And an engaging projection shaft 173 which is provided so as to protrude from one side of the pressing force transmitting shaft 165 and engage with the pressing force transmitting shaft 165.

At this time, on the end of the engagement projection shaft 173, an inclined engagement portion 174 is formed which is inclinedly engaged with the pressing force transmission shaft 165 so as to be able to rotate stepwise at intervals of 90 degrees when the pressing force transmission shaft 165 is pressed.

When the pressing force transmission shaft 165 presses the flow path switching unit 170 linearly, the flow path switching unit 170 is rotated stepwise at intervals of 90 degrees by the action of the slant meshing portion 174 of the flow path switching unit 170 .

In other words, the flow path switching unit 170 can be rotated step by step at intervals of 90 degrees each time the pressurizing force transmitting shaft 165 is pressurized as shown in Figs. 13 (a) to 13 (d) The flow path switching through holes 172 of the flow paths 170 and 170 communicate with the direct water inflow passage 151 and the spray water inflow passage 152 or communicate with only one of them, (Fig. 13 (b)), the spray number (Fig. 13 (c)), and the mixed number of the direct water and the half number of spray water (Fig. 13 (d)).

The unit guide shaft 167 serves to guide the flow path switching unit 170. To this end, one end of the unit guide shaft 167 is fixedly coupled to the tail cap 163.

Finally, the unit spring 169 is interposed between the flow path switching unit 170 and the unit guide shaft 167, and is elastically biased in the direction in which the flow path switching unit 170 is returned to the home position. This unit spring 169 can be applied as a torsion coil compression spring.

The operation of the spray head 100 for a sink having such a configuration will be described.

In FIG. 2, the push button 120 is pressed once as shown in FIG. Then, the pressure transmitting shaft 165 pushed by the push button 120 pushes the flow path switching unit 170, causing the flow path switching unit 170 to rotate by 90 ° due to the action of the slant meshing portion 174. When the flow path switching unit 170 is rotated by 90 degrees, the flow path switching through holes 172 are changed in position to communicate with the direct water inflow path 151 of the valve body 150 as shown in FIG. Therefore, in this case, direct water is jetted alone.

In this state, the push button 120 is pressed once more. Then, the pressure transmitting shaft 165 pushed by the push button 120 pushes the flow path switching unit 170, causing the flow path switching unit 170 to rotate by 90 degrees due to the action of the slant meshing portion 174. When the flow path switching unit 170 further rotates by 90 degrees, the flow path switching through holes 172 are changed in position, and the direct flow inlet passage 151 and the spray water inlet flow passage 151 of the valve body 150, as shown in FIG. 152 in common. Therefore, in this case, half of the number of the direct water and the spray water is mixed.

When the push button 120 is continuously pressed in this manner, the spray number (FIG. 13C) and the mixed number of the direct water and the half number of the spray water (FIG. 13D) can be jetted step by step.

According to the present embodiment having the structure and operation as described above, it is possible to distinguish between the direct water and the spray water by pushing the push button 120 at one point without distinguishing the right and left positions as before The structure can be simplified, and in particular, since the efficient structure can mix the direct water or the spray water in half, it is possible to greatly improve convenience in use.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It is therefore intended that such modifications or alterations be within the scope of the claims appended hereto.
