Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device with a water stopping mechanism, which can switch between a water stopping state and a water discharging state by sliding a spindle provided on a water supply body.

[0002]

2. Description of the Related Art As a conventional hand shower with a water stopping mechanism as a water supply device, a primary flow path from a hose and a secondary flow path leading to a water discharge port are connected to a shower body connected to a faucet via a hose. A vertical hole that forms a water flow passage made of, and a horizontal hole that intersects the vertical hole is provided, and the columnar spindle that switches between a water discharge state that connects the two flow paths and a water stop state that shuts off both the flow paths is provided. The spindle is slidably inserted in a lateral hole, and the spindle has a notch around this axis, and the spindle is slid so that the notch communicates with the two flow paths in a water discharging state. In some cases, the outer peripheral surface of the spindle is slid so as to shut off the two flow paths in a water-stop state while being moved.

[0003]

However, in the conventional hand shower with a water stopping mechanism having the above structure, the spindle is provided with a sealing surface portion capable of closing the downstream end of the primary flow path. In the case of the water state, the spindle is slid to close the downstream end port by the sealing surface portion.However, the operation of switching the water stop state and the water discharge state by sliding the spindle is repeatedly performed. As a result, the sealing surface portion is worn away, and there is a risk that the use of the sealing surface for a relatively short period of time will start to impair the sealing performance.

Further, since the frictional resistance between the sealing surface provided on the spindle and the wall surface forming the lateral hole is large, the sliding operation of the spindle for switching between the water stopping state and the water discharging state is performed. The required force increased, and the operability was poor.

[0005] On the other hand, for example, there is a similar problem in a conventional watering nozzle with a water stoppage mechanism used for horticulture in general households.

That is, the present applicant provides a long tubular body having a valve body fixed at the downstream end and forming a supply flow path inside the housing of the grip by being urged in the downstream direction by a spring from the upstream side. A valve closing state in which the valve body contacts the valve seat, and a valve opening in which the cylinder moves in the opening direction against the urging force of the spring due to the pressing operation of the flow control lever, and the valve body separates from the valve seat. Although a watering nozzle configured to switch to the state is proposed (refer to the drawing and specification of Japanese Patent Application No. 11-336826), the cause is a pressing operation of the flow control lever, a movement of the cylinder, or a change in water pressure. Is applied to the O-rings provided at a plurality of locations between the housing and the cylinder,
The wear of the ring was so fast that the sealability could not be ensured for a long period. Further, when the water pressure changes greatly, the pressing operation of the flow control lever is hard, and the operation cannot be performed lightly only by the load of the spring.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide a water supply device with a water stopping mechanism which can secure a sealing property for a long period of time and has good operability.

And notches 17) and both ends (the sealing member 1).
Outer part than 4, 16;
2 and the shape of the water discharge button 13) may be different.

The biasing means 7 is, for example, a spring, one end of which contacts a protruding portion 8b of a tubular body 8 described later,
The other end is configured to be held in contact with a holding member 7a provided in the upstream end 1a of the primary flow path 1,
Thereby, the urging means 7 always urges the cylindrical body 8 toward the spindle 6.

The cylindrical body 8 is a substantially cylindrical member, and has a sealing portion (for example, an O-ring) 18 on the outer surface and an end surface 8a having an opening 8 'closed by the peripheral surface of the sealing surface portion 15.

An end face 10a having an opening 10 'closed by the peripheral surface portion 15 is formed in a curved shape. The inner wall of the tubular body 10 is provided with a protruding portion 10b that protrudes inward.

Next, the hand shower D having the above configuration
Will be described. First, the water stopping button 1
In a state in which the spindle 2 is pressed, the spindle 6 is stopped at a position where the water stops, and at this time, the peripheral surface of the sealing surface 15 blocks the two flow paths 1 and 2.

That is, when the water-stop button 12 is pressed and the spindle 6 is in the water-stop state, the opening 8 ′ of the cylindrical body 8 is formed on the peripheral surface of the seal surface 15.
And the end face 10a of the cylindrical body 10 having the opening 10 'comes into contact with each other, and each end face 8a, 1
Since 0a has a curved shape that can be in close contact with the peripheral surface of the sealing surface 15, the openings 8 'and 10' are closed by the peripheral surface. Therefore, the hot and cold water sent from the faucet provided upstream of the shower main body 11 to the shower main body 11 reaches the inside of the cylindrical body 8 at the downstream end 1 a of the primary flow path 1. It is not hindered by the sealing surface portion 15 of the spindle 6 which comes into contact with the end face 8a, and does not go downstream therefrom. Incidentally, even if the hot and cold water from the faucet goes to the downstream side of the cylindrical body 8, the upstream end 2 a of the secondary side flow path 2 abutting on the peripheral surface of the sealing surface 15 of the spindle 6 will be described. End face 10 of tubular body 10

And the hot water sent from the faucet provided upstream of the shower main body 11 to the shower main body 11 is in the cylindrical body 8 at the downstream end 1a of the primary flow path 1. After passing through the cutout portion 17, it passes through the cylindrical body 10 at the upstream end portion 2a of the secondary flow path 2 and directly proceeds to the downstream side of the secondary flow path 2 to form the water discharge port 3
Will be ejected.

In the hand shower D having the above configuration,
The portion where the spindle 6 sliding in the horizontal hole 5 comes into contact with the wall surface forming the horizontal hole 5 is mainly the seal members 14 and 16 only. The frictional resistance of the spindle 6 becomes small, the sliding operation of the spindle 6 can be performed with a relatively small force, and the operability is improved.

Further, the hand shower D having the above configuration
Then, the hot and cold water flowing in the vertical hole 4 leaks from the horizontal hole 5 because the end faces 8a of the cylindrical bodies 8, 10 provided in the vertical hole 4
10a and the sealing surface portion 15 of the spindle 6 provided in the lateral hole 5 are brought into close contact with each other to prevent the openings 8 'and 10' from being closed. By doing so, even if the end surfaces 8a, 10a of the cylindrical bodies 8, 10 and the sealing surface 15 that are in contact with each other are worn, the cylindrical bodies 8, 10 are constantly urged toward the spindle 6. , The end face 8 of the cylindrical body 8, 10 with respect to the sealing face 15 of the spindle 6
a, 10a will be kept in close contact with each other,

The hand shower D ₂ of the second embodiment is different from the hand shower D of the first embodiment,
The main difference is that a through hole 19 is provided in the spindle 6 instead of the notch 17.

The through hole 19 is provided, for example, in a radial direction perpendicular to the axial direction of the spindle 6. The direction of the through hole 19 is always parallel or the same as the direction of the vertical hole 4. The water discharge button 13 has a guide groove 20 for guiding the spindle 6. The sliding of the spindle 6 is caused by the movement of the guide groove 20.
Is always guided by a guide body 21 formed at an appropriate portion of the shower main body 11 (for example, near the opening of the lateral hole 5 on the side of the water discharging button 13). Is always kept parallel or identical to the direction of the vertical hole 4.

The present invention is not limited to the configuration in which the guide groove 20 is provided in the spindle 6 and the guide body 21 is provided in the shower main body 11. For example, the guide groove 20 is provided in the shower main body 11, and the guide body 21 is provided in the spindle. 6 may be provided. Further, the guide groove 20 and the guide body 21
May be provided in plurality. Further, the guide groove 2
0 and the guide body 21 may be provided on the water-stopping button part 12 side without being provided on the water-discharge button part 13 side, or may be provided on both the water-stopping button part 12 side and the water-discharge button part 13 side. Is also good.

Next, the hand shower D having the above configuration

That is, when the water stopping button 12 is pressed and the spindle 6 is in a water stopping state, the end face 8a of the cylindrical body 8 and the cylindrical body 10 Since the end faces 10a are in contact with each other, and the end faces 8a, 10a have a curved shape that can be in close contact with the peripheral surface of the sealing surface 15, the openings 8 ', 1
0 'will be closed by the peripheral surface. Therefore, hot water sent from the faucet provided upstream of the shower main body 11 to the shower main body 11 is supplied to the downstream end 1 of the primary flow path 1.
a, the end face 8a of the cylindrical body 8 is reached.
Is not hindered by the sealing surface portion 15 of the spindle 6 that comes into contact with the spindle 6, and does not go downstream. Incidentally, even if the hot and cold water from the faucet goes to the downstream side of the cylindrical body 8, the upstream end 2 a of the secondary side flow path 2 abutting on the peripheral surface of the sealing surface 15 of the spindle 6 will be described. Cylindrical body 10
And is not hindered by the end face 10a.

When the state where the water stop button 12 is pressed is switched to the state where the water discharge button 13 is pressed, the spindle 6 slides to a position where the water discharge state is established. At this time, the through hole 19 communicates with the two flow paths 1 and 2.

That is, when the water discharging button 13 is pressed and the spindle 6 is in a water discharging state, the opening 8 ′ of the cylindrical body 8 and the cylindrical body 10 are inserted into the through hole 19 of the spindle 6. The openings 10 ′ face each other, and the hot and cold water sent from the faucet provided upstream of the shower main body 11 to the shower main body 11 enters the cylindrical body 8 at the downstream end 1 a of the primary flow path 1. After reaching, through the through-hole 19,
The water passes through the inside of the cylindrical body 10 at the upstream end portion 2 a of the secondary flow path 2, goes directly downstream of the secondary flow path 2, and is discharged from the water discharge port 3.
