The guide portions 22 and 32 are integrally formed of resin as a whole. A male screw portion 22a to be screwed with the female screw 21b of the cap portions 21 and 31 has a smaller diameter than the male screw portion 22a and is formed on the outer periphery of the distal end. Spiral grooves 22b1 are formed opposite to each other, and spray liquid such as medicine introduced from the inner peripheral side is guided to the outer periphery through the through hole 22b2 to spray chemicals or the like into the cap portions 21 and 31. A diffusion part 22b for diffusing the liquid in a mist state; a diffusion part 22b and a male screw part 2
The base 22c is formed by reducing the diameter toward the outside on the other side via the inner side 2a and having a female screw portion (not shown) on the inner peripheral side.
Consists of Since the guide portion 32 has the same configuration as the guide portion 22, the male screw portion 22 a is 32 a and the diffusion portion 22 is
b is 32b and the base 22c is 32c, but is not shown in FIGS. 1 and 2.

The flow path changing portions 23 and 33 are formed integrally with resin as a whole, and guide the spraying liquid such as a medicine to the above-mentioned guide portions 22 and 32 and cap portions 21 and 31 so as to be in the vicinity of the tip. Cylindrical pipes 23a, 33a having external threads 23a1 formed therein, and a flow path of a spraying liquid such as a medicine flowing through the pipes orthogonal to the pipes 23a, 33a is changed to have a larger diameter than the pipes 23a, 33a. Change tubes 23b, 33b, one of which is closed and the other is open,
The fitting portions 23c and 33c are formed with diameters slightly larger than the openings of the change tubes 23b and 33b. Although the male screw 23a1 and the female screw of the base 22c are screwed together, it goes without saying that other means other than such connecting means may be used. The same applies to the guide section 32 and the flow path changing section 33.

The flow path change sections 23 and 33 are provided with change pipes 23b,
A configuration in which a predetermined flow pressure is applied by changing the release path of the spray liquid such as the medicine introduced into the inside of the pipe 33b and guiding the liquid whose release path is changed to the small-diameter pipes 23a and 33a. ing.

Next, the first spray unit 2 and the second spray unit 3
Is composed of cap portions 21 and 31, guide portions 22 and 32, and flow path changing portions 23 and 33, and connects the first spraying portion 2 and the second spraying portion 3 to each other to feed the liquid feed pipe 13.

The annular groove 25b5 has O
The ring 29 is inserted. O-ring 29 as a liquid-tight member
Is formed of a soft resin, but the O-ring 29 is not a soft resin, but may be an elastic member such as rubber. For example, a filling member or other members can be used.

As shown in FIG. 2A, when the first spray unit 2 faces in the same direction as the joint 25a of the connecting member 25, the O-ring 29 2
Since the upstream opening 23a1 of 3a is completely closed, it is possible to stop water. However, as shown in FIG. 2B, the O-ring 29 is configured to be wider than the diameter a of the upstream opening 23a1 of the pipe 23a. Although it is possible to completely stop water, it is possible to spray at any angle by adjusting the flow rate of the liquid instead of completely stopping water in a predetermined range before and after reaching the position Has become. Therefore, by adjusting the angles of the first spraying section 2 and the second spraying section 3, the flow rate of the liquid to be sprayed can be adjusted to spray at an arbitrary angle.
