By cutting the side of the groove 74 of the automatic opening and closing faucet 70 to form a locking jaw 82 to push the handle 81 clockwise to reach its limit point and then push it to the left again, the handle 81 It is configured to be caught by the locking jaw 82.

The method of forming the locking jaw 82 may be produced by a method of cutting out the side surface of the groove 74 by a press.

Figure 2 (e) is also similar to the configuration of Figure 2 (d) and only the screws and bolts (138) of the faucet 70, so the statement is omitted.

The principle of operation of the present invention as described above is as shown in Figure 2 (a) When pushed in the table direction, the upper end of the lever 10 pushes the bag 5 while rotating around the U-shape 9, so that the ceramic valve 6 fixed to the injection valve 4 is opened and water is opened. The water comes out of the water discharge pipe (7), which is magnetized during the passage through the magnet (24) and becomes magnetized water.

When the water extruded at high pressure reaches the coiled spring 112 through the drain hole 8, bubbles are generated and discharged through the plurality of holes 12 or collide with the inner wall of the water discharge pipe 7 to open the inner wall in a state where the water washing is bent. As it flows along, it flows out without splashing or splashing.

When the cover knob 17 pushed in the table direction is released, all the operated parts are returned to their original state by gravity hydraulic friction force, and the ceramic valve 6 of the injection valve 4 is closed, so that water is released.

Cloth Handle (17) If you push it to the limit point in the table direction and then to the left side again, the handle 16 will catch the water discharge pipe 7 and the stopping jaw 117. Even if the cover knob (17) pushed in the direction of the table is released, water does not return to its original state and water remains.

If the cover handle 17 is pushed to the right while the water is still coming out, the handle 16 which is caught on the catching jaw 118 of the recess 117 of the water jetting port 7 is removed from the catching jaw 118 of the recess 117. All parts that were operated while being released are returned to their original state, and the polishing plane of the ceramic valve 6 fixed to the injection valve 4 is closed while being in close contact with the polishing plane of the ceramic packing 14, so that water is released.

The cover handle 17 is pushed to the left while pushing the cover handle 17 to the left while the bending portion in the middle of the chain 150 arranged between the horizontal levers of the still water lever 48 is laid horizontally between the still water levers 48. The result is the same as if pushed in the direction of the surface, so that water continues to come out.

If water continues to rise in the sink 56 and the water level rises, the water enters the bucket 52 through the soft pipe 55, and the weight of the bucket 52 increases, so that the spring 131 contracts and the water is exponent. Since the horizontal portion of the lever 48 is rotated in the counterclockwise direction, since the cover handle 17 returns to its original shape, the water is released while operating in the same manner as described above.

When the water accumulated in the sink 56, the water level is lowered, the water level of the bucket 52 is also lowered the water level and its weight is reduced, so the horizontal lever clock of the index lever 48 by the elasticity of the contracted spring 131 The cover knob 17 rotates in the direction of Displaces in the direction of the water and water comes out again.

When the handle 40 is turned left and right, the overall water temperature is changed by the cartridge 35 according to the mixing ratio of the hot and cold water, which is the same as the known cartridge 35.

Throat tube (42) When turned forward in the direction of the table and pulled forward, the ceramic plane 72 of the ceramic valve 72 adhered to the injection packing 76 is stuck to the injection packing 76 while the bag 78 is pushed by the upper end of the necklining pipe 43. Water is released because it opens and separates from the polishing plane of (75).

However, since the valve 61 of the faucet 58 coupled to the end of the neck pipe 42 is closed, water does not come out and the handle 66 is held. When pushing in the table direction, the polishing plane of the ceramic valve 63 fixed to the injection valve 61 is separated from the polishing plane of the ceramic packing 75 which is fixed to the injection peking 76 and is opened. When the hand or the bowl is removed from the handle 66 that has been pushed in the direction of the table, the valve 61 is closed by water pressure and water is released.

Knob (66) to the limit If you push it to the left again while pushing in the table direction, the handle 66 is caught by the catching jaw of the groove 116. The water will continue to flow without pushing in the direction of the table.

At this time, if you want to stop the water to push the handle 66 to the right, the handle 66 is released from the locking jaw of the groove 116, and the water is returned to the original by the water pressure.

The principle of operation of FIG. 2 (b) can push out the valve 141 when water flows from the male pipe 118 side to the water discharge pipe 103, and at this time, a lot of water through the groove of the dowel shaped bag 86 This can go out, and when the water flows back, the valve 141 is in close contact with the bulging 85 of the annular jaw 95 so that the back flow is completely blocked.

At this time, the bag 86 and the bag 140 allows the valve 141 to be operated accurately without leaving the top, bottom, left and right by the annular jaw 95 and the flow bolt (199).

When the screwdriver is inserted into the groove 197 and the flow bolt 199 is combined, the bag 140 closes the valve 141 to the bulking 85 so that water cannot come out. Since a space is formed between the flow rate bolt 199 and the bag 140 pushing the bag 140, the water can push out the valve 141.

At this time, since the water passes well into the grooves 88 of the bag 140, the operation of the valve 141 is sensitive.

The hose 102 of the automatic hose 131 When pulled in the table direction, the bag 5 is displaced in the same direction and water is released when the ceramic valve 6 is opened. When the hose 102 that was pulled in the direction of the table is released, all the operated parts are returned to their original state by gravity and water pressure, and water is released.

The principle of operation of FIG. 2 (C) is the same as that of FIG. 2 (B), but the automatic hose 134 can be separated from the vertical pipe 93 by passing through the valve housing 193 and the tube 135. Since it is folded inward, the injection valve 4 is not released.

Since the principle of action of FIG. 2 (D) is similar to that of FIG. 2 (A), the description thereof will be omitted.

As described above, the effect of the present invention is that the ceramic valve and the ceramic closing have semi-permanent high durability, and because the ceramic packing is not stretched or contracted by external pressure, the ceramic valve is opened and closed while sensitively acting on the small displacement of the bag, so that water, oil, The gas supply can be cut off sensitively and accurately, and the switchgear, that is, the faucet is automatically opened and closed by gravity, water pressure, friction, buoyancy, elasticity, etc. In the impingement plate formed on the bag, a lot of bubbles are generated as the water extruded at high pressure collides, and the splash plate prevents the water from being extruded at high pressure without splashing or scattering and there is a catching jaw on the side of the groove to keep the water coming out. The eccentric union acts as an automatic hose while preventing backflow There are a variety of functions and effects, etc. are.
