A discharge hole 43a opened in the axial direction of the flow path 12 is formed in the bottom 43 of the truncated cone part 41, and the truncated cone part 41 has a direction intersecting the discharge hole 43a. The discharge hole 41a opened toward the front is formed in a double ring shape. Further, the horizontal portion 42 is formed with a discharge hole 42a opened in the same direction as the discharge hole 43a.

  Reference numeral 5 denotes a cylindrical cap formed with an inner diameter slightly larger than the cylindrical portion of the head 2, and an inner peripheral screw 51 to be engaged with the outer peripheral screw 25 formed on the head 2 is formed on the inner peripheral surface of one end. In addition, a stepped portion 52 that contacts the horizontal portion 42 of the first water spray plate 4 is formed on the inner peripheral surface near the other end.

  6 is a second water spray plate made of the same material as that of the first water spray plate 4, and is formed in a truncated cone shape as a whole, and is formed on the bottom 61 at the tip of the protruding portion 11 in the substrate 1. An inner peripheral screw 61a that is screwed to the outer peripheral screw 11b is formed, and a communication hole 62a is formed in a ring shape in the truncated conical portion 62. And the truncated cone part 62 is formed in the same shape as the truncated cone part 41 in the above-mentioned 1st water spray plate 4, and the collar part 62b is formed in an outer periphery, This collar part 62b is 1st. The shape is in contact with the back side of the horizontal portion 42 of the water spray plate 4.

  Next, the method for assembling each member described above will be described. The head 2 is integrated with the base material 1 by screws 3 in a watertight state. Next, the inner peripheral screw 61 a formed on the bottom 61 of the second water spray plate 6 is used to screw and fix to the outer peripheral screw 11 b of the protruding portion 11 of the substrate 1. Thereby, the second water spray plate 6 is fixed in the head 4.

  Further, in a state where the back surface side of the horizontal portion 42 of the first water spray plate 4 is placed on the sealing ring 26 in the opening of the head 4, the cap 5 is put on and the inner peripheral screw 51 is screwed to the outer peripheral screw 25 to rotate. As a result, the first water spray plate 4 is fixed to the opening of the head 2. In this state, since the flange portion 62b of the second water spray plate 6 contacts the back surface of the horizontal portion 42 of the first water spray plate 4, the back surface of the truncated cone portion 41 in the first water spray plate 4 and the second water spray plate 6 A gap g is formed between the first and second water spray plates 4 and 6 and the inner surface of the head 2.

Next, the flow when pressurized air and water or hot water fluid are supplied to the shower head assembled as described above will be described.
The fluid supplied to the flow path 12 becomes pressurized fluid by pressurized air and is discharged from the discharge hole 11c formed at the tip of the protruding portion 11 and discharged from the discharge hole 43a of the first water spray plate 4. A mist flow is discharged from both of the discharge holes 41a through a gap g formed between the watering plate 4 and the second watering plate 6 to the outside. At this time, the mist flow from the discharge hole 43a is discharged in the axial direction of the flow path 12, and the mist from the discharge hole 41a is discharged in a direction intersecting with the mist from the discharge hole 43a. The mist flow discharged from the discharge holes 41a and 43a is referred to as a first mist.

  Further, the discharge hole 11a formed in the protruding portion 11 is also mist-like and discharged into the storage space G, and the diameters of the discharge holes 41a and 43a of the first water spray plate 4 are supplied from the flow path 12. By setting the diameter so that the entire water amount cannot be discharged, the amount of water remaining in the gap g flows into the storage space G through the communication hole 62a of the second water spray plate 6, and the pressure in the storage space G Becomes higher, it is discharged as a second mist flow from the discharge hole 42a formed in the horizontal portion 42 of the first water spray plate 4.

  Here, since the second mist flow discharged from the discharge hole 42a is discharged in the axial direction of the flow path 12 from the opening direction of the discharge hole 42a, the first mist flow is the second mist flow. Diffusion is prevented by this, and the entire mist flow becomes a cylindrical mist flow. Therefore, a large amount of mist strikes a small area against the object to be cleaned, and the cleaning surface can be cleaned more effectively. It becomes.

  In the first embodiment described above, the fluid flow path 13 for supplying fluid to the flow path 12 to which pressurized air is supplied intersects in the orthogonal direction, so that the fluid supplied from the fluid supply source When the pressure is low, there is a problem that the amount of fluid supplied decreases. In addition, when hot water is supplied from a water heater, the pressurized air is at room temperature, so the temperature of the pressurized air is low, and the temperature of the mist discharged by the heat of vaporization to form mist. There was a problem that became low.

  Therefore, in the second embodiment shown in FIGS. 4 and 5, a decrease in the fluid supply amount and a decrease in the mist temperature are prevented. Hereinafter, although this Example is described, the same code | symbol as above-mentioned Example shows the same member, and description is abbreviate | omitted.

Is formed.

  With such a structure, when hot water is supplied into the flowing water pipe, the air pipe is heated, and the pressurized air flowing through the air pipe is also heated, so when the fluid and air are mixed, the first As in the embodiment, the flowing water can be prevented from being cooled by air. Therefore, the temperature of the mist flow discharged from the first watering plate 4 is higher than that of the mist flow of the first embodiment.

  In this embodiment, one end of the fluid flow path 13 in the head 1 is connected to the fluid hole 72 and the other end is obliquely connected to the flow path 12 along the air flow direction. The structure is as follows. By adopting such a structure, the fluid is drawn by the pressurized air flowing in the flow path 12, so that the amount of fluid flowing is larger than that in the first embodiment, and the cleaning is performed more. The effect can be improved.

  FIG. 5 is a front view seen from the mist discharge side, but the number of discharge holes 41a formed in the truncated cone portion 41 of the first watering plate 4 is larger than that of the first embodiment. It has become. This is because the amount of fluid flowing into the flow path 12 is larger in the second embodiment, so that even if a large number of discharge holes 41a are provided, the amount of fluid stored in the storage space G increases. It is also possible to obtain a mist flow from the discharge hole 42a of the parallel portion 42 for preventing the mist flow from scattering.

It is sectional drawing which shows the 1st Example which concerns on the shower head of this invention. It is an exploded sectional view same as the above. It is the front view seen from the side from which mist is discharged. It is sectional drawing which shows a 2nd Example. It is the front view seen from the side from which mist is discharged.
