The direct cut off portion 80 is engaged with the upper end of the operation shaft 40 penetrating through the recess groove 51 provided in the center of the upper surface of the pressing portion 50 so that the operating shaft can be raised and lowered by pressing operation. Equipped with a push button 81, between the bottom of the push button and the recess groove 51 to push the operating shaft to the upper by the elastic force of its own fastening bolt 41 tightly seals the through hole 37 It is to be equipped with an elastic spring 82 to be made.

Referring to the operating state of the present invention having the configuration as described above, first, by adjusting the height, the height of the interval adjusting portion 70 is spirally fastened to the outer periphery of the pressing portion 50, the rise of the pressing portion 50 Adjust the descent distance to adjust the water supply time arbitrarily.

In the initial state in which water is not supplied in this state, as shown in FIG. 1, the pressing part 50 is raised by the elastic force of the elastic springs 60 and 72, and the recess groove 51 provided in the pressing part is provided. Since the operating shaft 40 coupled to the push button is in a raised state as the push button 71 positioned at the piston is raised, a piston having a fastening bolt 41 provided at the lower end thereof is fitted into the cylinder 31. As the 35 is positioned at the upper end of the cylinder and maintains the state in which the through hole 34 of the cylinder cap 33 is tightly sealed, the water introduced into the body 21 through the supply pipe 23 is provided therein. Is introduced through the through hole 32 of the cylinder 31, the piston 35 tightly seals the through hole 34 of the cylinder cap to keep the flow of water blocked state of the water flowing into the cylinder Flow blocked Will be maintained.

When water is supplied in such a state, when the pressing portion 50 held by the elastic spring 60 is pressed, the elastic shaft 60 is forcibly compressed while the operating shaft as shown in FIG. 2 ( 40) is lowered.

When the operating shaft is lowered as described above, the piston 35 coupled to the lower end thereof by the fastening bolt 41 is pushed down to the lower part of the cylinder 31. At this time, the operating shaft is operated by the water pressure of the water located at the lower part of the piston. When the piston is initially lowered, the piston cannot be lowered together, and only the operating shaft is lowered, but when the upper surface of the piston 35 is in contact with the stopper 42 provided on the operating shaft 40, the piston (35) according to the lowering of the operating shaft from this time. ) Will be pushed down together.

When the stopping jaw 42 provided on the working shaft is grounded on the upper surface of the piston 35 as described above, the fastening shaft is located on the bottom of the piston by a distance from which the working shaft descends and is screwed to the lower end of the working shaft 40. As the bolt 941 is lowered, the cylinder located in the lower part of the piston by the pressure that pushes the piston 35 when a force to lower the operating shaft 40 from the through hole 37 provided in the center of the piston is generated. The water in the 31 is discharged to the upper part of the piston 35 through the through hole 37 and the recess 31 formed in the inner circumferential surface of the cylinder 31, and the piston 35 is lowered. When the opening hole 34 of the cap 33 is opened, water supplied into the cylinder 31 from the supply pipe 23 is discharged to the discharge pipe 24 through the opening hole 34 of the cylinder cap from this time. In this case, watering of water is performed.

When the piston 35 is lowered to the lower part of the cylinder 31 by the pressing of the pressing part 50 in the state as described above, and the water is supplied, the pressing part 50 that has been pressed is released. The elastic spring 60 generates a force to raise the pressing portion 50 due to the elastic pressure to raise the piston 35 which is downward, at this time, the piston 35 by the water pressure of the water supplied into the cylinder 31 ) Is temporarily raised to block the open hole, and gradually rises for a certain time to block the open hole.

That is, when the force applied to the pressing unit 50 is not applied, the operating shaft 40 coupled to the pressing unit 50 is raised due to the elastic pressure of the elastic spring 60, which is forcibly compressed. In the initial stage when the working shaft is to be raised, only the working shaft is lifted by the distance separated by the Pison tone 35 and the fastening bolt 41 so that the fastening bolt 41 is in surface contact with the bottom surface of the piston 35 so that the through hole 37 ) In the state that blocked) the force to raise the piston 35 by the elastic pressure of the elastic spring 60, the piston 35 is temporarily caused by the water pressure of the water supplied into the cylinder 31 Pressure of the water supplied and supplied into the cylinder 31 of the bottom surface of the piston 35 through the inlet groove 31a provided in the inner circumferential surface of the cylinder 31 through which the water is supplied through the opening hole. Piston 35 slowly Which will make victory.

While the piston 35 that has been lowered in the above state is raised, water is continuously supplied through the opening 34 of the cylinder cap 33, and the piston 35, which is raised, opens the opening 34. If it is sealed, the water supply is blocked.

If the use of water is completed while the water is being supplied, press the direct cutoff portion 80 provided at the center of the upper surface of the pressing part 50 so that a part of the water to be supplied is supplied into the cylinder 31 through the gap and gradually. Ascending piston 35 rises at a high speed so as to block the opening hole 34.

That is, when the push button 71 is raised in the recess groove 51 by the elastic force of the elastic spring 72 is pressed, the operation is coupled to the push button as it is compressed into the recess groove while compressing the elastic spring. As the shaft 40 descends, a part of the water to be supplied when the fastening bolt 41 closes the bottom surface of the through hole 37 while being provided at the lower end of the operating shaft is separated from the through hole. As the inlet flows into the cylinder 31 through the through hole 38 provided in the piston 35, the piston rapidly rises due to the pressure of the inflow, thereby blocking the open hole 34 temporarily. Will be.

In another embodiment of the present invention, the above-described direct shut off portions 80a and 80b may be provided at one side of the piston 35 and the center of the bottom surface of the cylinder 31 as shown in FIGS. 4 and 5.

As illustrated in FIG. 4, the direct shutoff part 80a provided at one side of the piston 35 is provided with a through hole 81a which is allowed to penetrate up and down at one side of the piston, and is closed at the bottom of the piston provided with the through hole. A plate 82a is provided, which is provided at the center of the upper surface of the sealing plate and is covered by the piston shaft 83a passing through the through hole so that the lower end is supported by the piston, and the upper end is supported by the finger piece 84a fastened to the end of the piston shaft. It is equipped with an elastic spring (85a) to allow the sealing plate to close the through-hole by the elastic force of its own.

When the direct cut off portion 80a pulls the pressing portion 50 upward by an artificial force, the piston 935 causes a force to rise due to the pressure generated momentarily, and thus the body through the water inlet pipe 23. As the water flowing into the inside of the 21 is compressed, the elastic spring is compressed by the pressure of the water to which the straight cutoff portion 80a provided in the piston, that is, the finger piece 84a on which the elastic spring 85a is held, is compressed. As the water is supplied into the cylinder through the through hole 81a at a temporary time while compressing the 85a, the piston rises in a short time to block the open through hole 34 to block the water supply at a time. It will be blocked.

Another embodiment of the present invention, the direct cut off portion 80b forms a through hole 81b through which water can be introduced into the center of the bottom surface of the cylinder 35 as shown in FIG. 5, and a piston penetrating the through hole. An elastic spring 85b is formed on the piston shaft 83b which penetrates to the bottom of the cylinder while the closing plate 82b for opening and closing the through hole 81b provided on the shaft 83b is positioned at the bottom of the cylinder. It is also possible to be inserted into the bottom surface and the fingering piece 84b.

When the pressing portion 50 is pulled upward by the artificial force as described above, the direct shutoff portion 80b is caused by the momentary action of the piston 35 positioned below the cylinder 31 due to the rise of the rod. The upward force is generated. At this time, the sealing plate 82b, which is provided on the bottom surface of the cylinder 31 and closes the through-hole 81b due to the expansion pressure in the cylinder maintained by the piston 35, is in close contact with the through hole 81b. When the elastic spring 85b rises while compressing to open the through hole 81b, water introduced into the space 22 inside the body 21 rapidly flows into the cylinder 31 through the through hole 81b. As a result, the piston temporarily rises, thereby blocking the opening and blocking the water supply.

As described above, in the present invention, when the pressing portion held by the elastic spring is pressed, water is supplied to the water, and when the pressing portion is released, the water is supplied to the water and the piston lowered to the pressing portion is gradually released. When a certain time passes and the piston rises, the rising piston closes the opening of the cylinder cap tightly so that the water is not supplied. Therefore, when the user does not artificially block the water supply, the piston automatically Blocking the water supply will have the effect of reducing the amount of water wasted more than necessary.
