Description

[0001] FAUSET OF PUSH TYPE FOR SAVING TAP WATER [0002]

The present invention relates to a pushbutton type water-resistant type faucet having a large water saving effect and an improved quietness of operation of a valve body.

When the push button type faucet is pressed, the stem or the plunger with the diaphragm moves forward to open the valve seat, the water is discharged to the outlet of the faucet main body. When the hand is released from the pressed push button, the push button and the stem or plunger And the valve plate is closed and the valve seat is shut off to stop the water supply. [0005] Patent Literature 10-0660930 discloses that a plunger fastened to the tip of a push button is tubular, And a through hole is drilled in a radial direction at a predetermined distance, and the plate is connected to the tip thereof. The body portion having an O ring on the inner peripheral surface is fastened to the water supply pipe at its tip, and the plunger moves linearly along the axial direction every time the water supply and water supply are interrupted.

In this prior art, the water is also used by pushing the button habitually, but when the button is pressed in the non-powered state, the working distance to reach the rear end of the main body is long. It takes a long time to get to the point, and the return of the volleyball and the water ball is slowed correspondingly, and it is pointed out that water saving is ineffective.

It is also a problem that a rattling noise is generated even when the button is pressed and returned because of the clearance between the outer peripheral surface of the main body and the inner peripheral surface of the button. In addition, the plunger moving in the axial direction during water supply and water shutoff is inevitably subject to friction whenever the water supply hole passes the O-ring, which makes it easy to apply an external shock to the O-ring. If the O-ring is damaged, there is a possibility of leakage, and the frequency of O-ring replacement is also high.

In addition, the structure in which the button and plunger are instantly returned by the return spring with strong elasticity causes the return shock to be large, the impact noise to be disturbed to the ear, and the possibility that the plunger may swing in the cross- The movement of the button and plunger is not quiet.

The circular tubular plunger inserted into the circular tubular valve body may protrude along the direction of pushing the button, and if the button is suddenly turned or pulled to one side, there is a possibility that the plunger rattles and leaks.

The angle valve disclosed in Japanese Patent Application Laid-open No. 10-2015-0088463 is inserted into a water supply pipe which is withdrawn by a water supply pressure and a return spring to block the front of the rear end of the water supply pipe. Behind the safety pipe, A safety valve (valve seat) is attached to the rear of the water supply pipe so that the safety pipe goes forward by the advancing distance of the water supply pipe at the time of water supply and is synchronized with the safety pipe. The stem with the stems loosely fitted to the stem ball is resiliently supported by a compression type coil spring for the leaf spring which is less resilient than the hydraulic pressure. The stem of the safety lever tube is closed when not watered. If water is let out, press the operation lever to advance the safety pipe and the safety lever pipe, then turn it to one side and lock it in the valve body The water coming into the water pipe flows into the gap formed between the circumference of the safety pipe and the inner circumference of the water pipe, pushes the valve plate and feeds the flow channel of the safety lever pipe, and water is fed to the outlet pipe. The tube is returned by the water pressure and the return spring to cut off the rear end front of the water supply pipe and the safety lever tube escapes from the rear end of the water supply pipe and stays in the empty space in the valve body, I will stay.

This angle valve can be regarded as a push button type faucet in that it pushes the operation lever to advance the safety pipe and pushes the water supply channel. However, after advancing the safety pipe, turn the operation lever to one side, Because of the difference, it is distinguished from the push-button type water pump, and the expression "quasi-push button type water pump" is suitable.

In any case, the moment the button is pressed and released, the side plate is immediately withdrawn by the water pressure, and the valve seat must be closed to shut off the water supply and the water saving effect is expected. Since the water supply is continued even when the operation lever is unlocked, none.

Patent No. 10-0660930 Patent Document 10-2015-0088463

The present invention seeks to provide a push button type water-resistant faucet with an emphasis on increasing the water saving effect, improving the quietness of operation of the button and the variant, and improving the safety of the O-ring for preventing water leakage.

When a button is pressed and a toilet seat is opened to release water from the button, the button and the side plate are simultaneously returned to seal the toilet seat, thereby stopping water supply. In the faucet storage chamber And a sleeve thread having a female thread for fastening the sleeve at the tip thereof; A stem hole for guiding the stem of the side plate to move in a linear direction silently without radially swinging the stem of the side plate in the axial direction, and a water hole is drilled in the peripheral wall, A sleeve having an O-ring for preventing water leakage to the sleeve thread and having a male thread to be fastened to the female thread for fastening the sleeve; A button having guide grooves guided in the button guide; A stem attached to the sleeve at the tip of the sleeve to penetrate the stem and then to the button to provide silent movement by the stem of the water supply and water supply interruption; And a return spring loaded between the button and the button guide of the sleeve.

The water hole is radially drilled between the front and rear O-rings, and a ring-shaped water groove is formed at the same position as the water hole of the sleeve in the sleeve chamber to guide water flowing out to each water hole smoothly through the water outlet.

When pressing the button to drop the plate from the tip of the sleeve and watering, of course, the moment the button is released from the pressed button, the diaphragm is retracted by the hydraulic pressure at the inlet side and the return spring, and the tip of the sleeve is blocked again to stop the water supply. Operation is quiet because it moves in the right posture by the stem ball. The steady-state operation of the stem has a positive effect on the button, and it does not shake off when pressed or returned.

As soon as the hand is released from the button, the plate is returned by the water pressure on the inlet side and the return spring, and the water supply is interrupted by blocking the tip of the sleeve for the seat replacement, so that the water saving effect is larger than that of the conventional plate or plunger mounting type faucet.

Unlike the conventional plunger type, in which the water ring in the main body passes through the O-ring at the time of water supply and water supply, since the stem moving in the sleeve during the water supply and water supply interruption does not contact the O- There is no risk of damage.

The sleeve chamber 13 is a cylindrical circular hole for housing the sleeve. A female screw 16 is formed at the tip end of the sleeve chamber 13 having a smaller inner diameter than the sleeve chamber 13. The female screw 16 is provided for fastening and fixing the tip end of a sleeve to be described later. At an intermediate position of the sleeve chamber (13), an annular water passage groove (19) for facilitating water supply is formed. On the inlet 11, a tip 17 for clamping the flow rate adjusting tip 18 may be added.

The button 20 is a pushing type and has a guide groove 21 for the button guide of the sleeve and a female thread 22 for fastening the rear end of the stem is formed at the center of the rear end of the guide groove 21. The guide groove 21 has a mechanical tolerance which is required when designing the shaft and shaft hole between the inner diameter of the button guide and the outer diameter of the button guide so that the button 20 is guided to the button guide and moves silently when the button 20 is pressed .

The sleeve 30 is integrally formed with the button guide 31. The stem 31 is pierced axially in the center of the button guide 31 and the water hole 32 is drilled at the tip thereof. The leading end of the water supply hole 32 is a toilet seat. The stem hole (31) has a mechanical tolerance between the inner diameter and the outer diameter of the stem to allow the stem to move smoothly when the stem is advanced or retracted.

A through hole (33) is formed in the circumferential wall of the sleeve (30) at a position equal to the through hole (19). The water supply hole (33) is drilled radially to promote the source activity of the water supply.

O rings 34 and 35 for preventing water leakage are mounted on the front and rear sides of the water supply hole 33 through the front end and the rear end of the sleeve when the sleeve 30 is put in the sleeve chamber 13, On the outer circumferential surface, a male screw (36) for fastening to the female screw (16) provided at the tip of the sleeve is formed.

The body 40 is composed of a stem 41, a side plate 42 and an O-ring 43. The stem 42 has a mechanical tolerance between its outer diameter and the stem hole 31 that is essential for designing the shaft and the shaft hole so as to move silently by the stem hole 31 when operated and the female screw 22 in the button 10 The male screw 44 engaging with the male screw 44 is formed. Ring 42 is attached to the tip end of the stem 41 for opening and closing the water supply hole 32. The O-ring 43 is fitted in the stem 41 directly behind the side plate 42, ). &Lt; / RTI >

The return spring 50 is disposed between the bottom surface of the button around the female thread 22 and the rear end of the button guide 31 and returns the instantaneous button 20 when the button 20 is released, (40) are simultaneously returned together.

2, the stem 41 is inserted into the water hole 33 and the stem hole 32 of the sleeve 30 and the return spring 50 is inserted into the guide groove 21 of the button 20, And then the male screw 44 of the stem 41 is fastened to the female screw 22. The sleeve 30 is constantly urged by the return spring 50 toward the side plate 42 and is trapped between the side plate 42 and the button 20. At this time,

The sleeve 30 is inserted into the sleeve chamber 13 and turned into one side to fasten the male screw 37 to the female screw 16 to fix it. The water hole 34 communicates with the water outlet groove 19 and the O rings 35 and 36 seal the portion of the sleeve chamber 13 excluding the water outlet groove 19. The water outlet hole 42, (33). Water supply is not achieved.

In FIG. 3, when the button 20 is pressed in the state of FIG. 2, the guidance spring of the button guide 31 advances smoothly while compressing the return spring 50. The stem 41 is advanced as much as the forward distance of the button 20, and the valve plate 42 opens the water supply hole 33. The water in the waiting state on the side of the inlet 11 flows out to the water outlet 34 simultaneously with the opening of the water outlet 32 and flows to the outlet 12 through the water outlet groove 19.

The button 20 is immediately returned by the return spring 50 and the diaphragm 40 is pulled by the button 20 and the inlet 11 acting on the plate 42, The side water pressure is restored more quickly by the added force and the water supply hole 33 is shut off to enhance the water saving effect.
