DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a water purification shower according to the present invention will be described with reference to the drawings.
[0017]
The problem of the present invention is that it is suitable for use as a water purification shower that is easy to operate and can stop the water frequently without causing annoyance to the user of the water purification shower, and prevents waste of the purification ability of water and desalting material. Can do.
[0018]
FIG. 1 shows a water purification shower 1 according to an embodiment of the present invention. In FIG. 1, the shower 1 includes a head 2, a grip 3, a cartridge 4 containing a desalting material, a water stop portion 5, and an operation portion 6.
[0019]
The structure of the flow path is that raw water supplied from the shower hose 8 enters the raw water inlet 54 and is guided to the water stop 5, and passes through either the raw water flow path A or the purified water flow path B from the shower plate 22 of the head 2. Discharge as
[0020]
FIG. 2 shows an enlargement of the water stop portion 5 during water flow. The water stop unit 5 includes a water stop valve 51, a water stop hole 52, and a raw water inlet 54, and the water stop valve 51 rotates around a valve rotation shaft 53.
[0021]
When water flows, the raw water flows from the raw water inlet 54, passes through the water stop hole 52, and is guided to the cartridge 4 in the grip 3.
[0022]
FIG. 3 shows an enlargement of the water stop part 5 at the time of water stop. At the time of water stoppage, the water stop hole 52, which is a water passage for the raw water, is blocked by the water stop valve 51, so that the raw water does not flow and the raw water does not flow into the cartridge 4.
[0023]
On the other hand, although the raw water flow path A and the purified water flow path B are formed inside the water purification shower of the present invention shown in FIG. 1, the water stop hole 52 is common to the raw water flow path A and the purified water flow path B. It is a flow path. Since the water stop hole 52 is closed by the water stop valve 51, both the raw water flow path A and the purified water flow path B are closed, so that the discharge from the shower plate 22 is stopped.
[0024]
In the present invention, the flow path common to all the flow paths is, for example, when the water is branched into the raw water flow path and the purified water flow path in the shower, and when the flow is merged, It is a flow path.
[0025]
The means for switching between the water flow state shown in FIG. 2 and the water stop state shown in FIG.
[0026]
The operation unit 6 includes an operation piece 61 and a two-stage locking mechanism 62. When the operation piece 61 is operated, the two-stage locking mechanism 62 is operated in conjunction with the operation piece 61, and the operation is stopped by the operation of the two-stage locking mechanism 62. The water valve 51 opens and closes.
[0027]
FIG. 4 shows an exploded view of the two-stage locking mechanism. As shown in FIG. 4, a valve operating rod 625 for rotating the water stop valve 51 around the valve rotation shaft 53 is slidably inserted, and the tip of the valve operating rod 625 is in contact with the front surface of the member 625 and the valve joint 626. Are fitted, and the valve operating rod 625 and the water stop valve 51 are integrally connected.
[0028]
The two-stage locking mechanism 62 includes a guide cylinder 621, a reciprocating cam 622 that is inserted to the inner tip of the guide cylinder 621, abuts against the operation piece 61, meshes with the reciprocating cam 622, and other than the valve operating rod 625. The rotary cam 623 is engaged with the end, and a spring 624 that biases the valve operating rod 625 forward (rotary cam 623).
[0029]
When the user switches from the water flow state shown in FIG. 2 to the water stop state shown in FIG. 3, the operation piece 61 is pressed once. When the operating piece 61 is pushed, the reciprocating cam 622 and the rotating cam 623 slide in the guide tube 621, contract the spring 624, and slide the valve operating rod 625. When the rotating cam 623 is disengaged from the guide groove of the guide cylinder 621, the rotating cam 623 rotates by fitting with the reciprocating cam 622 and the phase shifts, and the operation piece 61 hits the tip of the guide cylinder 621 and stops moving. At this time, the water stop valve 51 is pushed by the valve operating rod 625 and rotates around the valve rotation shaft 53 to close the water stop hole 52 and stop the flow of raw water.
[0030]
Next, the repulsive force of the spring 624 acts to push back the valve operating rod 625, the rotating cam 623, and the reciprocating cam 622. At this time, the rotating cam 623 is out of phase, is caught in the guide groove of the guide cylinder 621, stops moving, fixes the position of the valve operating rod 625, and maintains the state where the flow of raw water is stopped.
[0031]
In addition, when the user switches from the water stop state shown in FIG. 3 to the water flow state shown in FIG. 2, the operation piece 61 is pressed once as in the case of water stop. When the operation piece 61 is pushed, the reciprocating cam 622 and the rotating cam 623 slide in the guide tube 621. When the reciprocating cam 622 is engaged with the rotating cam 623, the rotating cam 623 rotates and the phase shifts to return to the original phase, and the operation piece 61 hits the tip of the guide tube 621 and stops moving.
[0032]
Next, the repulsive force of the spring 624 acts to push back the valve operating rod 624, the rotating cam 623, and the reciprocating cam 622. At this time, since the rotating cam 623 has returned to its original phase, the rotating cam 623 moves without being caught by the guide groove of the guide cylinder 621 and is fitted to the tip of the valve operating rod 625 moving by the repulsive force of the spring 624. The valve joint 626 pulling the water stop valve 51 opens the water stop hole 52 and allows the raw water to pass through the cartridge 4.
[0033]
In the embodiment shown in the example, the water stop valve 51 is a hatch type valve, and since the water stop hole 52 can be fully closed and fully opened, the generation of pressure loss can be suppressed as much as possible.
[0034]
Further, the water stop valve 51 fully closes the water stop hole 52 to stop the water. However, if there is no problem in use, the water stop valve 51 is not completely closed and causes a slight leak and acts on the water stop valve 51. The pressure may be reduced.
[0035]

A path that is ejected from the plate 22 as a shower.
[0037]
On the other hand, the purified water flow path b flows from the raw water inlet through the water stop portion 5 and the water stop hole 52 to the inner peripheral surface side of the cylindrical cartridge 4 and passes through the inside of the cartridge 4. At this time, residual chlorine in the raw water is removed or decomposed. After that, it passes through the outer peripheral surface of the cartridge 4, passes through the switching unit 7, enters the head 2, and refers to a path for spraying from the shower plate 22 as a clean water shower.

Moreover, when selecting raw | natural water by operation of the switch part 7, it carries out by pushing in switching rod A71a. Thereby, the water stop ball 72 moves and the raw water passage 73 is opened. At this time, both the raw water channel a and the purified water channel b are opened, but the purified water channel b has a larger pressure loss than the raw water channel a by the amount of the cartridge 4, that is, the raw water has a low pressure loss. Passing selectively through the path a, raw water is discharged from the head 2.
[0042]
Here, the switching valve of the switching unit 7 is a ball valve using the water stop ball 72, but a butterfly valve, a cock valve, or the like may be used as long as it can close the raw water flow path.
