DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment shown in FIG. 1 is a watering nozzle capable of variously changing water shapes. The nozzle main body n of the nozzle for watering includes a tubular portion 1 and an enlarged portion 2 that extends forward. A male screw 2 a is formed on the outer periphery of the opening of the enlarged portion 2.

In the male screw 2a of the nozzle body n,
The shower head 3 is attached, and the shower head 3 is formed by integrally forming a stopper tube 4 and a shower plate 5. In addition, the shower head 3 has a shape that is line-symmetric with respect to the shower plate 5 in the cross-sectional shape shown in FIG. That is, the shower plate 5 is positioned at the center of the stopper tube 4 in the front-rear direction, and the shower plate 5 is
The lengths L1 and L2 up to the opening are made equal. And
Internal threads 4c and 4d are formed on the inner peripheral surfaces 4a and 4b of the stop cylinder 4 divided into front and rear portions with the shower plate 5 as a boundary. The female screws 4c and 4d are designed to engage with the male screw 2a of the enlarged portion 2. The enlarged portion 2 of the nozzle body n can be inserted into the stopper cylinder 4 in either direction from the inner peripheral surface 4a side or 4b side. Also, as a matter of course, the female screws 4c and 4d can be screwed into the male screw 2a of the enlarged portion 2. Then, when the two are screwed in this manner, the opening end of the stopper tube 4 is formed in the stepped portion 2 b formed in the enlarged portion 2.
In this case, the stop cylinder 4 is prevented from moving any further.

On the other hand, a large number of eye holes 6 are formed in the shower plate 5, and annular convex portions 7, 7 are formed on both surfaces of an outer peripheral portion of the shower plate 5. The annular convex portions 7, 7 and the inner peripheral surfaces 4a, 4b are combined to form annular seal grooves 8, 8, and a seal member 9 having a rectangular cross section is fitted into the seal grooves 8. In addition, the above-mentioned enlarged section 2
Has an annular protrusion 2c formed at the end thereof, and when the stopper tube 4 hits the step 2b of the enlarged portion 2, the annular protrusion 2c is formed.
However, the dimensional relationship of each part is determined so that the seal member 9 fitted into the seal groove 8 is pressed while being dented. As described above, since the annular projection 2c is pressed against the sealing member 9 while being depressed, a perfect sealing function can be expected in the meantime. In addition, if the pressure contact force of the tip of the enlarged portion 2 to the sealing member 9 is sufficiently maintained, a sealing function can be expected without the annular projection 2c. However, it is natural that a more perfect sealing function can be expected when the annular projection 2c is provided as described above.

In the center of the shower plate 5, a spout 1 is provided.
0 is formed. Then, on both sides of the shower plate 5 and around the spout 10, there are sealing projections 11, 1 and 2.
1 are formed. Since each part of the shower head 3 is formed as described above and is formed in a symmetrical shape with respect to the shower plate 5 as described above, the nozzle main body can be moved from either the inner peripheral surface 4a side or the 4b side as described above. n of the enlarged portion 2 can be inserted, and the female screws 4c and 4d
can be screwed into a. In other words, the nozzle body n and the shower head 3 can be fitted in exactly the same relationship regardless of whether the enlarged portion 2 is inserted from either the inner peripheral surface 4a side or the 4b side. However, when the shower head 3 is turned over, the seal member 9 must be replaced. The present invention has the greatest feature in that the shower head 3 is turned upside down as described above to remove algae and the like clogged in the eye holes 6, but this point will be described in detail later. explain. The male screw 2a and the female screws 4c and 4d constitute a connecting means for connecting the nozzle body n and the shower head 3.

The inside of the nozzle body n is configured as follows. That is, a support tube 12 having an axial center line coincident with the cylindrical portion 1 is provided in the enlarged portion 2.
Is advanced to the position of the step 2b as described above,
The tip 12 a of the second fitting part fits perfectly with the sealing convex part 11 of the shower head 3. And the tip 1 at this time
Water leaking from the periphery of the jet port 10 is prevented by the pressure contact force between the shower plate 2a and the shower plate 5, and the fit between the distal end portion 12a and the convex portion 11 for sealing.

Further, by providing a support tube 12 for bringing the tip portion 12a into contact with the shower plate 5, the cylindrical portion 1 is provided.
And an enlarged portion 2, and a shower channel 13 is formed in the enlarged portion 2. The support cylinder 12 includes a base end 12b, an intermediate part 12c, and a distal end 12a, and has a smaller diameter from the base end 12b toward the distal end 12a. In the base end 12b,
A flow passage 12d composed of a plurality of slits is formed, and a switching tube 14 in the tube portion 1 described later is formed through the flow passage 12d.
And the shower channel 13 are communicated with each other.

The switching cylinder 14 is provided on the supporting cylinder 12 as described above. The switching cylinder 14 is screwed with the cylinder portion 1 and is relatively rotated to move the switching cylinder 14 in the axial direction. It is made to reciprocate.
The switching cylinder 14 as described above has a large-diameter portion 14a that fits in the base end portion 12b and a medium-diameter portion 14b that fits in the middle portion 12c.
And a small-diameter portion 14c that fits into the distal end portion 12a, and an adjusting rod 14d formed at the distal end of the small-diameter portion 14c. When the adjusting rod 14d is at the position shown in the figure, the large-diameter portion 1
The flow channel 14 e formed of a hole formed in the support cylinder 1 a
The support tube 12 and the shower channel 13 are communicated with each other by wrapping with the flow passage 12d formed in the second tube 2.

At this time, since the tip 12a is completely closed by the seal 15, the switching cylinder 14
Is ejected from the eye 6 through the shower channel 13. Therefore, the water shape in this case is a shower water shape. However, when the switching cylinder 14 is slightly moved rightward from the state shown in FIG. 1 to reduce the amount of lap between the flow passage 12d and the flow passage 14e, the amount of water is reduced by the reduced amount of wrap. The shape is Jiro water shape. Also in this case, it is natural that the distal end portion 12a is closed by the seal 15.

When the switching cylinder 14 is further moved rightward from the above state, the flow passage 12d and the flow passage 14e are completely staggered, and the flow of both of them is shut off. However,
At this time, the small diameter portion 14c is
Since the water exits from a, the water guided to the switching cylinder 14 is spouted from the spout 10. At this time, depending on the position of the enlarged end portion of the adjusting rod 14d with respect to the ejection port 10, the shape becomes a diffusion water shape or a direct water shape.

Next, the operation of the watering nozzle of this embodiment will be described. This type of watering nozzle is used by connecting it to a hose, but if the hose is left without draining after use, algae will be generated in the hose. If water is spouted from the shower plate 5 in this state, algae and microorganisms are clogged in the eye holes 6 of the shower plate, so that water is not spouted. When algae are clogged in the eye holes 6 as described above, the shower head 3 is once removed from the enlarged portion 2 of the nozzle body n, turned over, and then attached to the enlarged portion 2 again. When water is spouted from the shower plate 5, the algae and microorganisms are blown off by the force of the spouting water, so that the clogging of the eye holes 6 is eliminated. The causes of clogging of the eye holes 6 are not limited to algae and microorganisms generated in the hose. For example, when groundwater is used, iron and gravel contained in it also cause clogging. In any case,
The obstacles that block the eye holes 6 accumulate on the upstream side of the eye holes 6, so that the obstacles can be easily removed by using the shower plate 5 upside down as described above.

As described above, the sprinkling nozzle of the first embodiment can eliminate the clogging only by mounting the shower head 3 on the nozzle body n with the front and back thereof reversed. In other words, water can always be sprinkled in a clean state without cleaning the cumbersome eye holes 6. In the first embodiment, the inner peripheral surfaces 4a, 4b
Are equal in length, but they need not necessarily be equal in length. In short, no matter which surface of the shower head 3 is in front, if the female screws 4c and 4d formed on the inner periphery of the stopper tube 4 have a length that can be connected to the male screw 2a of the enlarged portion 2, Good.

However, while holding the opening end of the stopper tube 4 against the step portion 2b, the holding force of the seal member 9 is reduced by the shower head 3
In order to make them equal on both sides, it is preferable that the inner peripheral surfaces 4a and 4b have the same length. The feature of the first embodiment is that the shower head 3 can be attached to the enlarged portion 2 even if the shower head 3 is turned upside down. This mounting structure
The present invention can also be applied to a watering nozzle having any other shape, for example, a watering nozzle which cannot switch the water shape.

In the second embodiment shown in FIG. 2, a stopper tube 4 formed on a shower plate 5 of a shower head 3 is connected to the inside of an enlarged portion 2. A male screw 4e is formed on the outer periphery of the stopper tube 4 and a female screw 2e is formed on the inner peripheral surface 2d of the enlarged portion 2. The male screw 4e and the female screw 2e connect the shower head 3 and the nozzle body n. The point of connection is the first
Different from the embodiment. However, other configurations are the same as in the first embodiment. Therefore, the following description will focus on differences from the first embodiment. The same components as those in the first embodiment are denoted by the same reference numerals. In the shower head 3 of the second embodiment, the shower plate 5 is formed on the inner periphery of the stopper tube 4, and its outer shape is symmetrical with respect to the shower plate 5. That is, the stopper tube 4 is formed uniformly before and after the shower plate 5, and has a continuous male screw 4e formed on the outer periphery thereof.

On the other hand, a female screw 2e meshing with the male screw 4e is formed on the inner peripheral surface 2d of the enlarged portion 2 of the nozzle body n. An annular convex portion 2f is formed on the rear end side of the female screw 2e in the enlarged portion 2. This annular convex part 2
f and the inner peripheral surface 2d of the enlarged portion 2 together form an annular seal groove 16. The seal member 9 is fitted in the seal groove 16. Then, when the male screw 4e of the stop cylinder 4 is set in the female screw 2e of the enlarged portion 2 and the shower head 3 is turned, the opening end of the stop cylinder 4 abuts on the seal member 9. The sealing member 9 is pressed in a state where the stopper cylinder 4 does not advance any more, and a sealing function is exerted at this portion. As described above, at the same time that the opening end of the stopper cylinder abuts against the seal member 9, the support cylinder 12 is formed on the sealing projection 11 formed on the shower plate 5.
The tip portion 12a of the fits tightly to perform sealing at this portion.

Further, since the male screw 4e of the retaining cylinder 4 is formed continuously back and forth with respect to the shower plate 5, even if the shower head 3 is turned upside down, the male screw 4e is connected to the enlarged portion. 2 female screw 2e. That is, the shower head 3 can be attached to the nozzle body n regardless of which surface is in front. Therefore, when the shower head 3 is clogged, the shower head 3 is mounted upside down,
The clogging can be easily eliminated without cleaning the eye hole 6. In the second embodiment, since the stopper tube 4 is formed to have an equal length before and after the shower plate 5, the tip of the stopper tube 4 is kept in the sealing member when the shower head 3 is mounted in either direction. By pressing 9, a sealing function can be exhibited. However, if the sealing between the enlarged portion 2 and the shower head 3 is performed at a position other than the tip of the stopper tube 4, it is not necessary to make the front and rear lengths of the stopper tube 4 equal.

In the third embodiment shown in FIG. 3, similarly to the second embodiment, a male screw 4e is formed on the outer periphery of the stopper tube 4, and the stopper tube 4 formed on the shower plate 5 of the shower head 3 is enlarged. 2
Are connected inside. And the male screw 4e
The shower head 3 and the nozzle body n are connected to each other by the female screw 2 e formed on the inner periphery of the enlarged portion 2.
The same components as those in the second embodiment are denoted by the same reference numerals. However, the watering nozzle of the third embodiment shown in FIG. 3 is such that the sealing between the enlarged portion 2 and the shower head 3 is not performed at the open end of the stop cylinder 4 but at the outer periphery of the stop cylinder 4. Nozzle. For this purpose, the stop cylinder 4
A pair of annular seal grooves 17, 17 are formed on the outer periphery of the male screw 4e on the outer periphery of the male screw 4e, and the seal members 18, 18 are fitted therein. A seal receiving portion 2g is formed on the inner periphery of the enlarged portion 2 behind the female screw 2e.

Then, the shower head 3 is moved to the enlarged portion 2.
When attached to the rear, the rear seal member 18 and the seal receiving portion 2g work together to exert a sealing function. At this time, the front seal member 18 does not function as a seal, but when the shower head 3 is turned over, the seal member 18
Combined with this, it exerts a sealing function. As shown in FIG.
Also in this watering nozzle, since the shower head 3 is symmetrical in the front-rear direction, even if the shower head 3 is turned over, both can be used as the same watering nozzle. Therefore, clogging can also be eliminated by displacing the shower head 3 in the watering nozzle of the third embodiment.

In the fourth embodiment shown in FIG. 4, the stopper tube 4 is formed only on one side of the shower plate 5, and a male screw 4e is formed on the outer periphery thereof. The male screw 4e and the female screw 2e formed on the inner peripheral surface 2d of the enlarged portion 2 connect the shower head 3 and the nozzle body n. The same components as those in the first embodiment are denoted by the same reference numerals. However, the water spray nozzle of this embodiment is not of the type that switches the water form, but sprays only with the shower water form. So, shower plate 5
Has only an eye 6 and no central outlet. Further, unlike the other embodiments, a member that partitions the passage is not provided in the enlarged portion 2.

In this embodiment as well, the shower head 3 can be mounted on the nozzle body n in the opposite direction, but in the state shown in FIG. 4A, the end 3d of the stopper tube 4 presses the seal member 9. Then, a seal can be made at this part. In addition. This seal member 9 is, like the second embodiment of FIG.
It fits into a seal groove 16 formed by an annular convex portion 2f formed in the enlarged portion 2 and an inner peripheral surface 2d. on the other hand,
FIG. 4B shows a state in which the shower head 3 in FIG. 4A is mounted upside down. Since the sprinkling nozzle has no member in the enlarged portion 2 that abuts the shower plate 5, the shower head 3 is advanced and coupled until the shower plate 5 presses the sealing member 9 as shown in FIG. be able to. In this case, the shower plate 5
Presses the sealing member 9 to seal it. Also in this embodiment, clogging can be eliminated by reversing the shower head 3. The shower head 3
When the shower head 3 is mounted with its front and back reversed, the position of the shower head 3 with respect to the enlarged portion 2 moves slightly back and forth, but does not affect the water spray function.

In the fifth embodiment shown in FIG. 5, the shower plate 5 of the shower head 3 is made flexible. Further, the position of the seal member 9 provided at the distal end of the enlarged portion 2 is located behind the distal end portion 12a of the support tube 12 formed inside. Since the outer peripheral portion of the shower plate 5 is pressed against the seal member 9, the shower plate 5 of the shower head 3 is curved. Other than that, it is the same as the first embodiment. Before the shower head 3 is attached to the enlarged portion 2, the shower plate 5 is flat without being curved.

The shower head 3 is attached to the stop cylinder 4
The female screw 4d is engaged with the male screw 2a of the enlarged portion 2 and is coupled to the enlarged portion 2. However, in the fifth embodiment, the sealing projection 11 of the shower plate 5 is
Even if it fits snugly with the tip 12a of the second stop 2, the stop cylinder 4 is further rotated until the opening end of the stop cylinder 4 hits the step 2b and stops, so that the two can be deeply connected. Then, as shown in FIG. 5, when the stopper tube 4 is joined until it hits the stepped portion 2 b, the shower plate 5 is
The seal member 9 is pressed. in this way,
When the stopper tube 4 is coupled to the enlarged portion 2 so that the shower plate 5 presses the sealing member 9, the distal end portion 12a of the support tube 12 pushes the center of the shower plate 5 forward. Bend. Note that the support tube 12 constitutes the pressing means of the present invention.

As described above, even if the shower head 3 is curved, the function of the watering nozzle is almost the same as that of the first embodiment. However, since the eye holes 6 face outward as compared to the case of a flat surface, the area of water sprayed during showering is increased. When the watering nozzle is used in the state shown in FIG. 5 and clogging occurs, the clogging is eliminated by mounting the shower head 3 in the opposite manner as in the other embodiments. When the female screw 4c of the retaining cylinder 4 is coupled to the male screw 2a of the enlarged portion 2 with the shower head 3 upside down, the opposite surface is curved and convex. Further, if the shower plate 5 of the shower head 3 is made flexible, the shower plate 5 can be curved by being attached to the nozzle body n without being curved at the time of molding. That is, the curved shower plate can be easily formed with the same mold as that for forming a flat shower plate.

The sixth embodiment shown in FIGS.
The length of the male screw 2a formed on the outer periphery of the fifth embodiment is longer than that of the fifth embodiment. An annular seal groove 19 is formed on the outer periphery of the enlarged portion 2, and a seal member 20 is provided therein. Other than that, it is the same as the fifth embodiment. As described above, this sprinkling nozzle has a long male screw 2a formed on the outer periphery of the enlarged portion 2, so that even when the female screw 4d of the stopper tube 4 is slightly connected to the male screw 2a, the water spout nozzle shown in FIG. As shown in (2), the shower plate 5 can abut on the tip 12a of the support tube 12. In this state, although the shower head 3 is not curved, the distal end portion 12a of the support tube 12 is not bent.
Are fitted into the sealing projections 11 formed on the shower plate 5, so that sealing can be performed at this portion.

Thus, the shower plate 5 can be used as a flat watering nozzle. At this time, a gap is formed on the outer periphery of the enlarged portion 2 between the tip of the stopper tube 4 and the step portion 2b, and the male screw 2a is left by the gap L3. In addition, stop cylinder 4
Inside, a gap L4 is formed between the tip of the enlarged portion 2 and the outer peripheral portion of the shower plate 5. Since there is such a gap, the shower head 3 can be further deeply coupled. However, if the smaller one of the gaps L3 and L4 disappears, the coupling between the shower head 3 and the enlarged portion 2 cannot be further deepened.

If the stop cylinder 4 is further deeply joined from the state shown in FIG. 7 until the opening end of the stop cylinder 4 abuts against the step 2b on the outer periphery of the enlarged portion 2, the shower plate 5 is bent, and the state shown in FIG. And the watering area becomes wider. When the shower head 3 is mounted upside down, the female screw 4
It can be used as two types of watering nozzles depending on the depth of connection between c and the male screw 2a. If the connection between the female screw 4c and the male screw 2a is made shallow, the shower plate 5 can be used as a flat shower head 3, and if deeply connected, the shower plate 5 can be used as a curved shower head 3.
Regardless of whether it is a flat surface or a curved surface, clogging can be eliminated by replacing the front and back of the shower head 3.

In the seventh embodiment shown in FIG. 8, the eye holes 6 formed in the shower plate 5 of the shower head 3 are tapered. Otherwise, the configuration is the same as that of the first embodiment, and the operation and effect are the same. The mold used when forming such a tapered eye hole 6 is tapered. On the other hand, the mold used for forming the parallel eye holes of the other embodiments has a thin pin shape. The thin pin-shaped mold is easily broken or worn. In other words, the tapered forming die for forming the eye holes 6 of the shower plate 5 of this embodiment is tougher than the die for forming eye holes of the other embodiments as described above because the base is thick. Although the hole diameter of the eye holes 6 is different between the front surface and the back surface of the shower plate 5, the jet flow is regulated by the smaller hole diameter. Therefore, the water flow does not change regardless of which surface is the front. Such a tapered eye hole 6 can be used in any of the embodiments.

In the first to seventh embodiments, the screw connection is used as the connecting means between the shower head 3 and the enlarged portion 2. However, another method may be used. For example, in the eighth embodiment shown in FIG. 9, a pair of stop projections 21 are provided on the outer periphery of the enlarged portion 2. Further, a pair of notches 22a and 2
2b. These notches 22a, 22b
Has an L-shape.
Are formed at positions corresponding to the stopper projections 21. And this notch 22a or 22b
Then, the shower head 3 and the enlarged portion 2 are connected by turning the shower head 3 after inserting the stopper convex portion 21. Incidentally, such a coupling means comprising the stop projection 21 and the notches 22a and 22b can be applied to any of the embodiments.

In the ninth embodiment shown in FIGS. 10 and 11, the shower head 3 comprises a shower plate 5 and a ring member 23 which is a fixing member of the present invention. And
Through this ring member 23, the enlarged portion 2 of the nozzle body n
The shower head 3 is attached to the rim. The shower plate 5 of this embodiment has the same structure as the first embodiment of FIG. 1 except that the stopper tube 4 is not integrally formed as in the other embodiments. The shower plate 5 has the same shape on both sides. The nozzle body n is exactly the same as that of the first embodiment. The watering nozzle of the ninth embodiment includes a ring member 23, and the shower head 3 is attached so that the shower plate 5 is sandwiched between the ring member 23 and the enlarged portion 2. The ring member 23 has a female screw 23a formed on the inner periphery as shown in FIGS. This female screw 23a is
It is connected to a male screw 2a formed on the outer periphery of the enlarged portion 2. A seal member 24 having a U-shaped cross section is fitted to the outside of the annular projections 7 formed on the shower plate 5.

The shower head 3 of this embodiment is similar to that of FIG.
As shown in (b), the seal member 24 is detached or attached in an integrated state. And
In the shower head 3, since the shower plate 5 has the same shape on both sides, it can be attached as it is even if the front and back are replaced. Therefore, the watering nozzle of this embodiment can also eliminate clogging by replacing the front and back of the shower plate 5. Further, as shown in FIG. 11B, if the seal member 24 and the shower plate 5 are integrated and removed from the nozzle body n, the seal member 24 will not be lost.

The method of connecting the ring member 23 and the enlarged portion 2 is not limited to the screw connection, but may use the connecting means of the eighth embodiment. Also, shower head 3
The fixing member for fixing to the enlarged portion 2 is not limited to the ring member 23 as in the ninth embodiment, but may be any fixing member that can fix the shower plate 5 to the nozzle body n. For example, a screw hole is formed in the enlarged portion 2, a through hole is formed in the shower plate 5, and the shower plate 5 can be directly fixed to the enlarged portion 2 by a screw penetrating the through hole. In this case, the screw serves as a fixing member.

[0036]

According to the first to fourth aspects of the present invention, the shower head or the shower plate can be attached to the nozzle body with its front and back reversed. Therefore, when clogging of the shower head occurs, it is possible to replace the front and back of the shower head without cleaning the eye holes.
Clogging can be easily eliminated. In particular, according to the fourth aspect, since the shower head can be curved, the front surface of the shower head can be formed as a convex surface to widen the watering range. Further, since the shower plate has flexibility, the center portion can be extruded and curved by the pressing means of the nozzle body even if it is flat at the time of molding. That is, the shower plate can be formed as a flat surface.
Therefore, a curved shower plate can be obtained without using a complicated mold.
