The second adjustment member 3b has a curved tube body. The second adjustment member 3b includes a first end portion on which the first sleeve portion 32 is provided, and a second shaft tube portion 31. And a second end provided. A liquid-tight O-ring 342 is attached to the second shaft tube portion 31, and the first shaft tube portion 33 of the first adjustment member 3a is the first sleeve of the second adjustment member 3b. The second shaft tube portion 31 of the second adjustment member 3 b is engaged and inserted into the second sleeve portions 221 a and 221 b of the joint 2.

The coupling between the first adjustment member 3a and the second adjustment member 3b is as shown in FIG. The first shaft tube portion 33 of the first adjustment member 3a is a conical body having a portion 331 opposite to the outer diameter portion, the end of the male screw portion 34 is a first enlarged portion 341, and the second The inner diameter portion of the first sleeve portion 32 of the adjusting member 3b has a stopper portion 321 and a width portion 322 at the outer diameter portion. After the cone of the first shaft tube portion 33 is fitted into the first sleeve portion 32 by momentum, the warped portion 331 engages with the stopper portion 321, and the first enlarged portion 341 contacts the width portion 322. Engagement fixation is formed by contact.

The second shaft tube portion 31 of the second adjustment member 3b is a cone having a portion 311 opposite to the outer diameter portion, and the inner diameter portion of the open end of the second sleeve portions 221a and 221b of the joint 2 is the positioning portion 222. And a stopper portion 223. After the conical body of the second shaft tube portion 31 is fitted into the second sleeve portions 221a and 221b by momentum, the warped portion 311 engages with the stopper portion 223, and the second enlarged portion 312 becomes the second Engagement and fixation are formed by contacting the sleeve portions 221a and 221b.

The spray head 35 is generally cup-shaped and has a substantially cylindrical outer surface, and is suitable for being accommodated in the first accommodating portion 351, the second accommodating portion 352, and the accommodating portion. A spacer 37 and a plunger 38 are provided, and a through hole, that is, a nozzle 353 for positioning the convex portion 371 of the spacer 37 is provided at the center of the outer surface of the spray head 35. The inner bottom portion of the first accommodating portion 351 is provided with a second accommodating portion 352, and the diameter of the second accommodating portion 352 is smaller than that of the first accommodating portion 351, and the first accommodating portion 351 is provided. Has a female screw, the second accommodating portion 352 has an internal contact surface, and has a through hole that penetrates the outer surface of the internal contact surface spray head 35, that is, a nozzle 353. Yes.

The plunger 38 has a first step portion and a second step portion, the first step portion has a larger diameter than the second step portion, and the first step portion is a second step portion. The first step portion is provided with an inflow passage 381 in the vicinity of the second step portion, and the inflow passage 381 is one or more. The second stepped portion is provided with one or more discharge passages 382 in a distributed and uniformly arranged ring shape. In the present embodiment, the two passages are arranged apart from each other, and extend to the end surface of the second stepped portion and are curved to form two shifted inclined passages 382a and 382b, and the inclined passages 382a, The end of 382b is in contact with the outer diameter portion of the recess of the spacer 37. The passage width of the discharge passage 382 is narrower than that of the inflow passage 381, so that the space is made smaller by the plunger 38 in the accommodating portion into which water flows in, and the water flow becomes large and small due to the change in the space form, and high pressure is generated. Then, the water flow passes through the small hole 372 of the spacer 37, and the water pressure is further instantaneously released from the nozzle 353, so that a mist-like spray is generated.

The spacer 37 is a disc body, and one edge thereof is provided with a convex portion 371 having an arc convex shape, and the maximum outer diameter of the convex portion 371 is substantially larger than the diameter of the nozzle 353, and the convex portion. Since the outer diameter of the arc at the highest point of 371 is smaller than the hole diameter of the nozzle 353, the edge of the hole of the nozzle 353 is pressed down. The opposite side surface of the convex portion 371 is a concave portion, and a small hole 372 is provided at the center of the convex portion 371, and the outer diameter of the spacer 37 is generally smaller than the inner diameter of the second accommodating portion 352. Thus, after the spacer 37 is assembled to the second accommodating portion 352, the abutting inner abutting surface is further pressed by the plunger 38. The small hole 372 can eject water from this point as a mist-like spray. The end of the first step portion of the plunger 38 abuts on the flange portion 343 of the inner wall wall of the male screw portion 34 of the first adjusting member 3a, so that the plunger 38 is fixed so as not to be detached from the first accommodating portion 351. doing.

The adjustment operation shown in FIGS. 5 and 6 is possible by assembling with the above-described members. The first adjustment member 3a is rotatable on the second adjustment member 3b in the radial direction, and the second adjustment member 3b is rotatable on the second connecting portion 22 of the joint 2 in the radial direction. The spray head 35 disposed opposite to the adjustment member 3a can adjust the spray direction at multiple angles.

The adjusting means 3 of the present invention has many kinds of implementation methods, and is not limited to this embodiment diagram. The adjusting member may be a ball valve or may be a shaft sleeve that integrates the joint 2 and the second adjusting member 3b and adjusts the first connecting portion 21 of the joint 2, and the adjusting member. May be one or more.

Since there are two sets of adjusting means 3 in the embodiment of the present invention, the first adjusting member 3a and the second adjusting member 3b are also two sets, and each of the second connecting portions 22 of the joint 2 has its second set. The two sleeve portions 221a and 221b are assembled.
