The water flow control valve 1 has a hot water or water supply valve function, and has a water supply port 11 that is an inlet of hot water or water supplied from a mixing tap A attached to a bathroom or the like, and an outlet that is an outlet. A water mouth 15 is formed.

A first cylinder 12 communicating with the water supply port 11 is provided at the rear (right side in FIG. 2) in the water flow control valve 1, and larger than the diameter D1 of the first cylinder 12 at the front (left side in FIG. 2). A second cylinder 14 having a diameter D2 is provided, and the first cylinder 12 and the second cylinder 14 communicate with each other. Reference numeral R2 in the figure is an O-ring. Further, a through hole 16 is formed in the front wall 1 a in front of the second cylinder 14.

A piston 20 is slidably disposed in the water flow control valve 1, and the piston 20 has a structure in which a large-diameter rod 21, a flange 23, and a small-diameter rod 24 are integrally connected coaxially.

The large-diameter rod 21 of the piston 20 is slidably disposed in the first cylinder 12, and the flange 23 and the small-diameter rod 24 are disposed in the second cylinder 14.

Four grooves 22 are provided at equal intervals in the axial direction on the circumferential surface of the large-diameter rod 21. The groove 22 is provided from the rear end of the large-diameter rod 21 to a position away from the rear end 23a of the flange 23 by a certain distance L1. The number of the grooves 22 is arbitrary.
The rear end 21a of the large-diameter rod 21 is disposed at a certain interval from the water supply port 11, and a clearance 21b is provided between the entire peripheral surface of the large-diameter rod 21 and the inner peripheral surface 12a of the first cylinder 12. Are arranged. The clearance 21b can be set to an optimum value depending on the amount of water during operation, as will be described later, but can be determined in the range of 0.01 to 0.2 mm, and preferably about 0.025 mm.

The flange 23 is fixed to the front end of the large-diameter rod 21, and its diameter D3 is larger than the diameter D1 of the first cylinder 12, so that the rear end 23a of the flange 23 is in a state where no hot water or water is supplied. It is in close contact with the rear end 14a of the cylinder 14, and determines the stop position of the piston 20 in the cylinder.

A clearance 23 b is formed between the entire peripheral surface of the flange 23 and the inner peripheral surface 14 a of the second cylinder 14. This clearance 23b can be determined in the range of 0.005 to 0.25 mm.

Four grooves 23c are provided on the surface of the flange 23, and hot water or water flowing from the grooves 22 of the large-diameter rod 21 can flow into the second cylinder 14 without resistance. is there.

The small-diameter rod 24 is slidably inserted into the through hole 16 of the front wall 1a, and the tip 24a protrudes outside the water flow control valve 1. It is important that the surface of the small diameter rod 24 has a smooth surface finish as much as possible.
Reference numeral R1 in the drawing denotes a sliding O-ring for the small-diameter rod 24, which prevents water leakage from the second cylinder 14, and its material has sufficient durability against the hot water used.

A coiled compression spring 18 is incorporated around the small-diameter rod 24 and the operation of the piston 20 is assisted by the repulsive force of the compression spring 18. That is, the compression spring 18 acts as a force for returning the piston 20 to the original position when water supply from the water supply port 11 is stopped.

The carbon dioxide supply valve 3 is connected to the water flow control valve 1 by a connection bracket 40, and the tip 31a of the rod 31 for operating the opening and closing of the valve is disposed at a distance L3 from the tip 24a of the small diameter rod 24. . This distance L3 is the same as or substantially the same as the distance L1.
Further, a compression spring 32 for moving the rod 31 back and forth is provided inside. Reference numeral 9 denotes a hose from which carbon dioxide gas is sent from the carbon dioxide gas cylinder B.
Therefore, when the rod 31 is pressed by the small diameter rod 24 in the compression direction of the compression spring 32, the carbon dioxide supply valve 3 is opened and carbon dioxide is supplied from the hose 53 to the hose 52. When the pressing stops, the rod 31 returns to its original position due to the repulsive force of the compression spring 32 and the supply of carbon dioxide gas stops. The carbon dioxide gas supply valve 3 can use a product by existing technology.

A hose or tubular unit having a stirring means for hot water or water and carbon dioxide gas can be incorporated after the water outlet 15 of the water flow control valve 1. In the present embodiment, the shower head 6 or the stirring head 7 is incorporated at the tip of the hoses 54 and 55 having a function of stirring carbon dioxide gas and hot water or water.

That is, the hose 54 having the shower head 6 at the tip and the hose 55 having the stirring head 7 at the tip are connected by the water flow switch 4.
Either one of the shower head 6 or the agitation head 7 can be used alone.

The operation of the first embodiment configured as described above will be described.
By opening the mixing tap A, hot water or water is supplied into the water flow control valve 1. At this time, water pressure is applied to the rear end 21 a of the large-diameter rod 21 of the piston 20.

When the piston 20 moves forward by the distance L1 due to water pressure and the front end of the groove 22 provided on the circumferential surface of the large-diameter rod 21 exceeds the position where the space of the second cylinder 14 is reached (see FIG. 4), Water begins to enter the second cylinder 14, passes through the second cylinder 14, and is sent from the water outlet 15 to the hose 52 (see FIG. 5).

As the piston 20 advances, the tip 24a of the small diameter rod 24 advances by a distance L3, contacts the tip 31a of the rod 31, and begins to push in the rod 31. Thereafter, the piston 20 moves forward by the distance L2, so that the rod 31 is pushed in the distance L4 which is the same as the distance L2, and the carbon dioxide supply valve 3 is opened by the movement of the tip 24a of the small diameter rod 24. It is sent to the hose 52.

The hot water or water discharged from the water outlet 15 of the water flow control valve 1 is sent to the water flow switch 4 by the hose 52. As described above, the hose 53 is connected to the middle of the hose 52 so that the carbon dioxide gas is supplied with hot water or water. Is mixed. Hot water or water mixed with carbon dioxide gas is sent from the water flow switch 4 to the shower head 6 by the hose 54 or to the stirring head 7 by the hose 55 for use.

When the supply of hot water or water from the mixing faucet A is stopped, the water pressure in the first cylinder 12 and the second cylinder 14 decreases, and the compression spring 32 in the carbon dioxide supply valve 3 and the compression spring in the second cylinder 14 The rod 31 returns to the original position by the repulsive force of 18, the carbon dioxide supply valve 3 is also closed, and the supply of carbon dioxide is stopped. Next, the piston 20 is returned to the original position by the repulsive force of the compression spring 18 to be in the state shown in FIG.
At this time, since the rod 31 of the carbon dioxide supply valve 3 is separated from the small-diameter rod 24 by the distance L3, the carbon dioxide supply valve 3 is completely closed and the supply of carbon dioxide is reliably stopped.

On the other hand, when the piston 20 returns to the original position, the hot water or water filled in the first cylinder 12 on the rear end 21a side of the large-diameter rod 21 becomes resistance when the piston 20 moves backward.
However, since the hot water or water in the first cylinder 12 is pushed by the large-diameter rod 21 and flows into the second cylinder 14 through the clearance 21b provided between the first cylinders 12, the piston 20 has a resistance. It becomes smaller and can move smoothly.

The diameter D1 of the large-diameter rod 21 of the piston 20 compresses the pressing force required to open the carbon dioxide supply valve 3 in relation to the pressure of hot water or water to be supplied, that is, the compression spring 18 in the second cylinder 14. The force and the sliding resistance force of the small-diameter rod 24 and the O-ring R1 are set so as to obtain a pressing force that exceeds the total.

As described above, the piston 20 is operated by the water supply pressure from the mixing tap A to bring it into a water supply state, and the carbon dioxide supply valve 3 is opened by the pressing force of the piston 20 to supply carbon dioxide. Done.
When the water supply from the mixing tap A stops, the restoring force of the compression spring 32 in the carbon dioxide supply valve 3 closes the carbon dioxide supply valve 3 to stop the supply of carbon dioxide, and the piston 20 also returns to its original position. The return water supply also stops.

As described above, in the present invention, the above-described effects can be obtained by integrating the water flow control valve 1 and the carbon dioxide supply valve 3 and connecting them to the water supply port of the mixing tap A. These operations do not use electricity, and are all mechanical means, so they are safe especially for use in the bathroom.

An embodiment of the stirring head will be described with reference to FIGS.
The agitation head 7 includes a fixed portion 77 fixed to the end of the hose 55 at the rear end, and a connecting portion 76 that is connected to the fixed portion 77 and has a diameter that increases toward the front. The main body 71 is screwed into the front end of the connecting portion 76.

The main body 71 has a cylindrical shape with a diameter larger than that of the connecting portion 76, and the front end of the peripheral surface portion 73 is closed by the front plate 74. doing. Further, a plurality of discharge holes 72, 72... Are provided in the vicinity of the front plate 74 at the front end of the peripheral surface portion 73.

In use, when carbon dioxide gas and stirred hot water or water flow from the hose 55, they pass through the connecting portion 76 and flow into the space portion 75. The flowing hot water or water collides with the front plate 74 vigorously and is agitated in the space 75, and thereafter is expelled from the discharge holes 72, 72,. Therefore, hot water or water and carbon dioxide gas are further stirred to increase the carbon dioxide gas concentration, and are discharged in a cloudy state.
Further, the number, size, shape, configuration position, and the like of the discharge holes 72 are arbitrary and may be configured on the front plate 74.

On the other hand, a chain or a coil may be provided inside the hoses 54 and 55 to serve as stirring means. These chains and coils can be of various thicknesses, shapes, pitches, or lengths, that is, different types of chains and different types of coils can be adopted, and the number of pieces accommodated in the hose is not limited to one, and a plurality of pieces may be contained.

An embodiment of the coil will be described with reference to FIG. The coil 80 (81, 82, 83, 84) is disposed over the entire length of the flow path 59 of the hoses 54, 55, and one end or both ends are locked to the end portions of the hoses 54, 55 as necessary. In the figure, a part of the coil 80 (81, 82, 83, 84) is shown.

The coil 81 of Example 1 shown in FIG. 8A has the same coil diameter over the entire length, and a coil 81a having a large pitch and a coil 81b wound in close contact are alternately arranged. The length of the coil 81a is about 5 cm.
Since the coils 81a and 81b are alternately arranged in the coil 81, the coil 81a is prevented from changing the pitch by the action of the coil 81b and the shape of the coil 81 is stable even when the whole is long. To do. Therefore, the stirring effect described later is efficiently exhibited over the entire length, and it can withstand long use. The coil 81 has an advantage that it is the simplest in structure and easy to manufacture as compared with the other embodiments.

The coil 82 according to the second embodiment illustrated in FIG. 8B includes a combination of a portion having the same coil diameter and a portion in which the coil diameter changes.
In the drawing, three coils 82a wound in close contact with each other from the left to the right and two coils 82b having a large pitch are alternately and continuously arranged, and the right end coil 82a has a pitch. A coil 82c having a gradually decreasing diameter is provided continuously.
A coil 82f having a gradually increasing diameter is provided at the right end of the coil 82c via a small-diameter coil 82e wound in close contact with each other to form one pattern.
By connecting the coil 82a to the other end of the coil 82f, the pattern is repeated to obtain a long coil. The coil 82b is about 5 cm, and the coils 82c and 82f are about 10 cm.
This coil 82 changes the flow of hot water or carbon dioxide gas by alternately providing portions having the same diameter and portions where the diameter gradually changes, thereby enhancing the stirring effect.

The coil 83 according to the third embodiment shown in FIG. 8C is a combination of coils whose diameters change.
From the left to the right in the drawing, a small-diameter coil 83a wound tightly, a coil 83b having a pitch and a gradually increasing diameter, a large-diameter coil 83c wound tightly, and a diameter The coil 83e is gradually connected to form one pattern. This one pattern is repeated to obtain a long one.
The one pattern is about 30 cm, the diameter D8 of the coil 83a is about 4 mm, and the diameter D9 of the coil 83c is about 6 mm.
The coil 83 does not have the same diameter, and the diameter changes from small to large and from large to small, so that the flow of hot water and carbon dioxide gas can always be changed, and the stirring effect is enhanced. . The stirring effect is considered to be the best among the examples.

Here, the stirring action of hot water and carbon dioxide gas will be described using the coil 83 as an example.
As shown in the enlarged view (c-2) of FIG. 8 (c), carbon dioxide gas and hot water w flow from the left direction, and the hot water w hits the surfaces of the coils 83b, 83b,. At this time, since the diameter of the coil 83b is gradually increased, the hot water w flowing outside the coil 83b successively hits the coil 83. Similarly, the hot water w flowing inside the coil 83e is successively turned into the coil. 83, and the coil 83 is also shaken by this water flow. As a result, the hot water w becomes an irregular flow and is sufficiently stirred with the carbon dioxide gas, so that the carbon dioxide gas is efficiently dissolved.
As a result, a carbonated spring having a concentration of about 1000 pm is obtained.

  The coil 84 according to the fourth embodiment shown in FIG. 8D includes a coil 84a having a pitch that gradually increases in diameter from the left side in the drawing. In use, the coil 84a is continuously arranged in the hose 55 and used as a long one. There is an advantage that the length of the coil 84 can be freely changed by the length of the hose 55.

Normally, one coil 80 (81, 82, 83, 84) is arranged in the hoses 54, 55. However, the present invention is not limited to this, and a plurality of coils 80, 80,.・ Can be arranged. For example, as shown in FIG. 9A, the coils 80 having different diameters may be accommodated twice, and as shown in FIG. 9B, three coils 80 having the same diameter may be arranged.

A chain that is another example of the stirring means will be described with reference to FIG. The chains 87, 88 and 89 are disposed in the flow path 59 to stir hot water or water and carbon dioxide gas, and are disposed over the entire length of the flow path 59 of the hose 55 or hose 54, and one end or both ends are connected to the hose 55 as necessary. Alternatively, it is locked to the end of the hose 54 or the like. The figure shows a part of an example of a chain.

The chain 87 shown in FIG. 10 (a) is the most frequently used shape, so it is easily available and inexpensive.
Since the chain 88 shown in FIG. 10B has a complicated shape, the stirring efficiency of hot water or water and carbon dioxide gas is increased.
The chain 89 shown in FIG. 10 (c) has a merit that it is lightweight because it is formed by connecting spherical bodies so as to be able to swing with each other.
Although the chain has the same functions and effects as the coil 80, it is considered that the stirring is efficiently performed because the chain swings with the water flow from the coil 80.
