DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1-3, there is shown a spray device 10 according to the present invention. The spray device 10 includes a long feed pipe 11. The feed pipe 11 has a plurality of shower nozzles 12, which will be described in detail later, at predetermined intervals downwardly, preferably via a packing. Are screwed together. At one end of the feed pipe 11 is a liquid water drain 1
The adapter 14 provided with 3 is screwed, and the rotating body 15 is inserted into the adapter 14 so as to be capable of advancing and retracting and rotating. The rotating body 15 is provided with a valve portion 16, and the valve portion 16 is provided so as to come into contact with and separate from a valve seat 17 formed in the adapter 14 in accordance with the forward / backward movement of the rotating body 15.

Further, a rotary handle 18 is connected to one end of the rotary body 15, and the rotary body 15 is the rotary handle 1.
Similarly, when 8 is rotated, or rotated and moved back and forth, it is configured to be rotated, or rotated and moved back and forth. Further, a rotary brush cleaning body 19 is coupled to the other end of the rotary body 15, and the rotary brush cleaning body 19 also follows the rotation of the rotary body 15 and the rotary handle 18, or the rotation and advancing / retreating operations, in the feed pipe 11. Similarly, it is rotated, or rotated and moved back and forth. The rotary brush cleaning body 19 has a rotary shaft 20 which is inserted in the central portion of the supply pipe 11 over substantially the entire length of the supply pipe 11, and a brush body 21 fixed to the rotary shaft 20. is doing. In this case, the brush body 21 is approximately 90 degrees in the circumferential direction, as shown in FIG.
It is arranged at intervals of 120 degrees or 120 degrees,
The brush bodies 21 which are separated by a relatively short length along the axis of the rotary shaft 20 and which are adjacent to each other in the axial direction of the rotary shaft 20 are arranged so that their circumferential positions are different from each other, for example, by 60 degrees in terms of a rotation angle. It

On the other hand, when impurities are accumulated on the inner peripheral surface of the feed pipe 11 including the vicinity of the inflow orifice 22 of the shower nozzle 12, the rotary handle 18 is rotated to rotate the rotary brush cleaning body 19 through the rotary body 15. By rotating the brush body 21, the impurities accumulated on the inner peripheral surface of the feed pipe 11 can be reliably and sufficiently removed by the brush body 21. At this time, the rotary handle 18 is moved back and forth as necessary to retract the rotary body 15 to the position indicated by the dotted line in FIG.
The cleaning work may be carried out by rotating the rotary brush cleaning body 19 while keeping it away from the inflow state, and in this case, the impurities removed from the vicinity of the inflow orifice 22 by the rotary brush cleaning body 19 are the drain outlet of the adapter 14. It can be discharged together with liquid water from 13.

Accordingly, in the shower nozzle according to the first aspect of the present invention, the inflow orifice 22 to the ejection opening 24.
By tilting the direction of the nozzle from the downward vertical position as shown in FIG. 4 and attaching it to the water supply pipe 11, it is possible to prevent impurities in the spray liquid from being deposited downward and to be accumulated and to clog the nozzle. To prevent. In particular, as shown in FIG. 4, it is possible to incline 90 ° from the downward vertical position, and the flow path in the nozzle can be set so that the ejection direction from the nozzle ejection opening 24 is vertical.

Further, as is apparent from FIG. 4 as well, the shower nozzle 12 according to the second aspect of the present invention is provided with a relatively narrow inlet orifice 22 on the side of the feed pipe 11, and the inlet orifice 22 is provided. The flow path 23 immediately downstream of 22 is formed in a larger cross section than the inflow orifice 22, and is connected to the ejection opening 24 having a spray angle of 80 degrees, for example. That is, when the size of the inflow orifice 22 is about 1 mm, the size of the channel 23 is at least 1 mm or more, and if necessary, about 2 mm.

Therefore, the spray device 1 of the present invention described above.

If a spray liquid such as cleaning water or a sterilizing liquid is supplied, the valve portion 16 of the rotating body 15 is located in the closed state with respect to the valve seat 17, so that the spray liquid is sprayed from each shower nozzle 12 at a spray angle of 80 degrees, for example. Erupted. At this time, even if the spray liquid contains impurities, the size of the inflow orifice 22 on the side of the feed pipe 11 of the shower nozzle 12 is narrow, but the flow path 23 immediately downstream thereof is large. Therefore, the impurities contained in the spray liquid are less likely to be deposited in the vicinity of the inflow orifice 22, and are easily released immediately from the ejection opening 24 without being clogged.

In addition, as shown in FIG. 5, the shower nozzle 1
2a, the flow path 23 immediately downstream of the inflow orifice 22a
By adopting a configuration in which a portion 23b of the inlet a, which is closest to the inflow orifice 22a, is made larger than other portions, it is possible to remarkably reduce accumulation of impurities in the spray liquid and clogging.
