Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a watering nozzle connected to the end of a hose and used for watering and watering for home gardening. More specifically, the invention relates to a watering nozzle capable of appropriately selecting and switching the watering mode. Related to a spraying nozzle.

[0002]

2. Description of the Related Art As a sprinkling nozzle of this kind, a spout for spouting water supplied from a connected hose is provided at a tip end surface of a sprinkling nozzle body (hereinafter also referred to as a nozzle body or simply a main body). A water spray body (water spray plate) having a plurality of water outlets (water spouts) formed on the same end surface so as to obtain a plurality of types of water forms (water sprinkling forms) and having a water spout inlet connected to each water spout outlet. Is rotatably mounted so that the spout inlet comes into contact with the spout, and the sprinkler is rotated so that a predetermined spout inlet is aligned with the spout, thereby obtaining a desired water shape. (See Japanese Patent Publication No. 5-75463).

[0003] The shape of the plurality of water discharge outlets of such a sprinkler is configured as follows. For example, the shape of the water discharge outlet for flying a long distance in a straight (straight) thin water shape is formed in a substantially circular shape with a small diameter, and the shape of the water discharge outlet for a relatively thick water shape is larger than that. Are formed in a substantially circular shape.
Further, the shape of the water discharge outlet for forming a flat and fan-shaped water shape such as for washing an automobile so that water can be widely applied is formed in a slit shape. Further, the shape of the water outlet for shower water is a large number of minute holes. The spout outlet suitable for storing water in a bucket does not need to be scattered far away and does not require any momentum, and thus has an opening for securing a large water passage portion (water passage area).

However, in the above-mentioned conventional watering nozzle,
Connect it to the faucet with a hose and open the faucet appropriately.For example, if you want to spray straight water, rotate the sprinkler and connect the spout to the spout. The watering can be obtained by opening the watering nozzle by adjusting the lever and operating the lever. If it is desired to use shower water (water sprinkling) in the middle of the water sprinkling, the sprinkling body may be rotated so that the spout inlet for the sprinkling body is aligned with the spout. As described above, in this type of watering nozzle, a desired water shape can be selected by rotating the watering body even in the use process.

By the way, in such a watering nozzle,
Regardless of the type of water sprayed, water is sent from one spout of the main body and spouted. Therefore, except in cases where the water flow area of the spout is extremely small, the watering mode is basically changed. However, the amount of discharged water does not change much. In the case of a straight or flat water sprinkler, increasing the tapping degree of the faucet often causes too much momentum and makes it difficult to use the spigot. Therefore, the tapping degree of the faucet is adjusted to be relatively small.

[0006]

However, when the sprinkler body is rotated under such a condition that the degree of opening is small and the water form is changed to shower sprinkling, the momentum decreases, and water is not sprinkled from all shower holes. There was a problem that satisfactory water spray of satisfactory shape could not be obtained. In other words, for example, the shower water that should be sprayed in a conical shape as a whole does not become a clean conical shape but drips down, etc., and the watering area decreases, and it takes time to water plants and flowers etc. was there. In this case, it is sufficient to go to the faucet to adjust the open state, but that is troublesome.

In addition, even if the water flow is adjusted in this manner, if the water flow is switched again to a water shape suitable for a small flow rate such as a straight shape,
This time, the momentum is too high. In addition, when switching from a water discharge outlet having a small flow rate, such as a straight shape, to a water discharge outlet having a large water flow area provided for pool water, there is also a problem that the amount of water is insufficient, and it takes time to collect water. .

As described above, in the conventional watering nozzle, the watering form can be selected and switched by rotating the watering body, but the desired water amount cannot be obtained unless the open state of the faucet is changed. Therefore, when switching from a straight or flat sprinkling state in which an appropriate water form can be obtained with a relatively small flow rate to a shower or pool water discharge in which a relatively large flow rate is appropriate, the amount of water becomes insufficient. Conversely, when changing from a shower or reservoir spout to a straight or flat water form, the momentum will be too strong.

As described above, in the conventional nozzle, there is a problem that even if the watering mode can be switched, a water discharge amount according to the watering mode cannot be obtained. Under these circumstances, there is a demand for a watering nozzle to be lightweight and compact. For this purpose, if the watering body is made small, a plurality of water outlets formed in the watering body and the respective outlets of the main body through which the water flows are provided. The water area must be further reduced, and the above problem becomes more pronounced. The present invention has been made in order to solve such a problem, and in the case of a water type in which a large flow rate is suitable, such as shower sprinkling and spouting for pool water, or a small flow rate, such as straight sprinkling or flat type sprinkling. It is an object of the present invention to provide a watering nozzle capable of obtaining an appropriate amount of water according to the water shape, as in the case of a suitable water shape.

[0010]

According to the present invention, in order to solve the above-mentioned problems, a spout port for spouting water supplied from a connected hose is provided at a tip end surface of a watering nozzle body. On the surface, a sprinkler having a plurality of water outlets formed so as to obtain a plurality of types of water shapes and having a water discharge inlet connected to each water discharge outlet is rotatably mounted such that the water discharge inlet comes into contact with the water spray body. A sprinkler nozzle configured to obtain a desired water shape by rotating the sprinkler body and aligning a predetermined spout inlet with the spout port. Of the water discharge outlets, two water discharge inlets connected to the water discharge outlet are provided at a water discharge outlet for water flow suitable for discharging a large amount of water, and the two water discharge inlets are rotated by rotating the water sprinkling body so that the two water discharge inlets are the two jet outlets. Arranged to face In addition, one of the water discharge outlets of the water spray body, which is suitable for water discharge at a small flow rate, is provided with one water discharge inlet connected to the water discharge outlet, and the water discharge inlet is rotated by rotating the water spray body. Are arranged so as to face one of the two jets, and when the one spouting inlet faces one of the two jets, the sprinkler is connected to the other jet. Is configured to be closed.

[0011] The water discharge outlet for the water form to which the large flow water discharge is suitable is exemplified by a water discharge outlet for shower water or a water discharge outlet for reservoir water. In such a means, water is supplied through a single jet port to a water discharge port for a water form to which a small flow rate of water is suitable, such as straight water. Then, by rotating the sprinkler from a state where water is supplied from one such spout, two spouts connected to a spout for a water form (such as for a shower or for a reservoir) suitable for spouting a large flow rate are provided. When the water discharge inlet faces the two spouts, water is sent from the two spouts, so the flow rate increases by that amount, and the water is stored in a short time by vigorous shower water or low-speed spout of large flow without vigor. Water is made. That is, according to the nozzle for watering of the present invention, the amount of water can be switched between large and small in accordance with the water shape, so that an appropriate watering form can be obtained.

[0012] In the above means, the two spouts on the tip end surface of the watering nozzle body can be provided at the same distance from the rotation center of the watering body, but are preferably provided at different distances. That is, the two spouts on the tip surface of the watering nozzle body can be provided on one circumference centered on the rotation center of the watering body, but on different circumferences centered on the same rotation center. It is preferred to provide. By doing so, the degree of freedom in the arrangement (layout) of the water discharge outlet is increased, and the water sprinkler can be made compact.

[0013]

Is formed, and as shown in FIG. 6, is connected to a shower water discharge outlet (also referred to as a shower outlet) 21 via a hollow portion K1. In other words, the distance R1 from the center 31c of the circular plate portion 41 to the center of the water discharge inlet (also referred to as a shower inlet) 21a at a position closer to the inner periphery is equal to the tip surface 4
Is the same as the distance from the center 4c of the circular plate portion 41 to the center of the spout 6a at the inner peripheral portion, and the water discharge inlet (also referred to as a shower entrance) 21b from the center 31c of the circular plate portion 41 to the outer peripheral portion.
Is set to be the same as the distance from the center 4c of the tip end surface 4 to the center of the jet port 6b near the outer periphery.

Thus, by rotating the sprinkler 31, the two spouting inlets (shower entrances) 21a, 21b are formed so as to be aligned with the two spouts 6a, 6b of the main body 1, respectively. By sending water,
It is formed so that a relatively large flow rate of water can be introduced into the hollow portion K1 and water can be sprinkled from the water discharge outlet 21 forming a large number of shower holes (see FIGS. 2 and 6). When the sprinkler body 31 is rotated by 180 degrees from this position, and the shower inlet 21a located on the inner periphery is located on the side of the outlet 6b located on the outer periphery of the main body 1, the spout 6b located on the outer periphery is The circular plate portion 41 is configured so as to be kept watertight and closed via the attached O-ring packing 11. Incidentally, in this case, as will be described later, a spout 6a located at a position closer to the inner circumference is provided on the opposite side of the shower inlet 21a in the direction of the diameter D1 (for fan-shaped watering).
(See FIG. 7). A baffle (dispersion plate) 46 is provided on the tip end side (in the hollow portion K1) of the shower water discharge inlet 21b near the outer periphery, so that the water that has entered the hollow portion K1 is temporarily moved in the horizontal direction or through the horizontal direction. It is formed so as to be fed in the circumferential direction and to sufficiently fill the hollow portion K1.

As shown in FIG. 7, the two water discharge inlets 21 for the shower of the circular plate portion 41 are provided.
In the direction of the diameter D2 different from where the a and 21b are provided, a circle is formed around the circumferences Da and Db passing through the centers of the two water discharge inlets 21a and 21b around the center 31c of the circular hole 32. Two arc-shaped lower portions 22a and 22b, which are stepwise lower, are formed so as to form a water discharge inlet for pool water as described below.
Each of the arc-shaped lower portions 22a and 22b has an outer-spreading lower portion 4 that extends outwardly (triangularly) toward the outer peripheral edge.
7, 48 are provided in series, and the periphery thereof is formed so as to be continuous with the annular low portion 45.

However, as shown in FIG.
1 is rotated so that the arc-shaped lower portions 22a and 22b, which form the tops of the two lower portions 47 and 48, are aligned with the jets 6a and 6b of the main body 1, and when water is supplied from each jet below the jets, FIG. As shown by the middle arrow, the water passes through the two spouts 6a and 6b, and does not enter the internal space K1 of the watering body 31, but between the distal end face 4 of the main body 1 and each of the arc-shaped lower portions 22a and 22b. , And goes around the lower part 45 of the periphery of the circular plate part 41 through the lower parts 47, 48, respectively.
The water is discharged from the water discharge outlet 22 for storing water to the front of the water spray plate 51 at a low speed without resistance through a large water passage portion K2 having an annular shape between the inner cylindrical portion 52 and the inner wall portion 52. In addition, 49 in the circular plate portion 41 has such a size that the spout 6b at a position near the outer periphery of the main body 1 can be closed when the sprinkler body 31 is rotated 180 degrees from the position of the low-speed water discharge state (FIG. 9). This is a closed protruding surface which is circular and is protruded flat and flush with the surface of the circular plate portion 41 (see FIG. 7).

In this embodiment, as shown in FIG. 8, in addition to the water outlets 21 and 22 suitable for large flow water discharge as described above, water discharge outlets 23 to 26 suitable for relatively small flow water discharge are provided. ing. That is, such a hollow sprinkler 3
1 through the water sprinkling plate 51 and the circular plate portion 41, and the water spouting outlets (hereinafter also referred to as through water spouting outlets) 23 to 26 formed so as to be directly discharged from one of the spouts 6a. There are four cylindrical bodies (flow passages) 23t to 26t provided in the shape of a penetrating member, so that water can be discharged in different forms depending on the shape of the water discharge outlets 23 to 26 (FIG. 1).
0-13). However, the cylindrical bodies 23t to 26t connected to the water outlets 23 to 26 pass through the center of the inner part (6a) of the two outlets 6a and 6b of the tip end surface 4 of the watering nozzle body 1 near the inner periphery. They are arranged at appropriate intervals on the circumference Da (see FIGS. 7, 8, 10 to 13). That is, the center of each of the water discharge outlets 23 to 26, and the circular plate portion 41
Side end, i.e., water discharge inlet (through water discharge inlet) 23a-2
The centers of 6a are arranged at appropriate intervals on the same circumference Da having a radius extending from the center (rotation center) 31c of the water sprinkling body 31 to the center of the water discharge outlet 21a near the inner circumference for the shower.

The through water outlets (openings) 23 to 26
Has a small circular through water discharge outlet 23 to obtain a thin straight water shape, a through water discharge outlet 24 having a structure capable of obtaining soft spray-like water spray, and a slit shape to obtain a flat, fan-shaped water shape. The water discharge outlet 25 has a large circular shape in order to obtain a round water shape, and each of the water discharge outlets 26 has a relatively small flow rate. Then, as shown in FIGS.
t, 25t, 26t through water discharge inlets 23a, 24a, 2
When the water is supplied below the spout 6a at the position close to the inner circumference and the water is passed under the spout 6a, the water passes through one of the cylinders (23t to 26t) from the spout 6a, and the corresponding through water discharge outlet 23 to 26. From the outside to form a desired water shape.

When water is discharged by aligning the through-water outlets 23a, 24a, 25a, and 26a formed by the cylinders 23t to 26t with the outlet 6a located closer to the inner periphery, the outlet 6b located at the outer periphery is used. Is configured to be closed by the circular plate portion 41 via the O-ring packing 11 attached thereto. That is, it is configured such that water is supplied only from one jet port 6a at a portion closer to the inner circumference. When the water discharge inlet 24a of the cylindrical body 24t for spraying the mist is aligned with the jet outlet 6a on the inner peripheral portion, the jet outlet 6b on the outer peripheral portion is connected to the closing protruding surface 49 as described above. It is closed at.

In this embodiment, however, only when the shower water and the reservoir water are discharged, that is, when the water is discharged from the shower outlet 21 and the reservoir water discharge outlet 22, the two jet ports 6a, 6a,
6b, water is supplied only from the jet port 6a near the inner periphery at the time of other water discharge, and the jet port 6b near the outer periphery is closed.
In addition, the alignment with respect to the ejection port is performed, for example, by forming a specific mark (mark) on the outer peripheral surface (upper in FIG. 1) of the portion near the front end of the main body 1 and displaying “water shape display” on the outer peripheral surface of the watering body 31. Or a symbol, and the "water mark display" or the symbol may be matched to the specific mark.

Next, the operation and effect of the watering nozzle of this embodiment will be described as follows. That is,
A hose is connected between the hose connection part 3 of the watering nozzle and a faucet (not shown), the faucet is opened to a predetermined degree, and the watering body 31 is rotated appropriately under the hose, for example, for straight water. When the through-water discharge inlet 23a is aligned with the spout 6a at the inner peripheral portion (see FIG. 10), the spout 6a at the inner-peripheral portion becomes straight from the through-water outlet 23 via the through-water inlet 23a. Sprinkled. In such a water form, desired sprinkling can be obtained with a relatively small amount of water. Also, when water is supplied in accordance with the spout of the mist, the flat shape or the thick round water shape in accordance with the spout of the portion closer to the inner periphery, the respective through water spout inlets 24a to 26a are similarly connected to the portions closer to the inner periphery. What is necessary is just to match with the ejection port 6a (FIGS. 11 to 1).
3).

On the other hand, the sprinkling body 31 is rotated from such a sprinkling state, and the two spouting inlets 21a, 21b are used for showering.
To the two ejection ports 6a and 6b of the main body 1 (see FIG. 2). In this case, shower water is obtained from the shower outlet 21. In this case, the shower water is supplied from the two jet ports 6a and 6b to the two water discharge inlets 21a and 21b, so that a large amount of water is obtained. Therefore, a shower-like watering with a vigorous and clean shape can be obtained. When the water spray body 31 is rotated to match the two arc-shaped lower portions 22a and 22b with the two jet ports 6a and 6b of the main body 1 as shown in FIG. 9, water is sent from the two jet ports. And the distal end face 4 of the main body 1 and the respective arc-shaped lower portions 22a, 22
2b, respectively, passes through the outer-spreading lower portions 47 and 48, wraps around the lower portion 45 of the peripheral edge of the circular plate portion 41, and further reaches an annular space K2 between the outer tube portion 55 and the inner tube portion 52, which is large. A sprinkling plate 5 from a water discharge outlet 22 for reservoir water forming a water passage portion.
1 is discharged at a low speed without resistance. Thus, the accumulated water can be obtained in a short time by sending a large amount of water. In addition, since the water is discharged at a low speed, the nozzle does not fly out of the bucket.

As described above, in the watering nozzle of the present embodiment, a fan-shaped nozzle is used which is suitable for forming a thin straight water shape to a distant place, soft mist watering for a plant, etc., or washing a window glass of an automobile. An appropriate flow rate can be obtained even when switching from watering in a state in which a relatively small amount of water is preferable, such as watering, to a shower or reservoir water form in which a relatively large amount of water is preferable. In this example, the two ejection ports 6a, 6
b is arranged on a different circumference, that is, the distance from the center of rotation 31c of the sprinkler body 31 to the center of the two ejection ports 6a and 6b is changed, so that the layout becomes easier, and the sprinkler body 31 and the nozzle body 1 Since the diameter of the distal end surface 4 can be reduced, the nozzle itself can be made compact.

In the above embodiment, the two jet ports 6a and 6b on the tip end surface 4 of the water spray nozzle body 1 are provided at different distances from the rotation center 31c of the water sprinkling body 31, but the two jet ports 6a , 6b can be provided at the same distance from the rotation center 31c of the watering body 31. That is, as shown in FIG. 14, two jet ports 6a and 6b provided on the distal end face 4 of the main body 1 are arranged at a predetermined angle θ (for example, 150 degrees) interval with respect to the center 4c. As shown in FIG. 15, the sprinkler body 31 is rotatably attached to the screw hole 18 of the tip end surface 4 in the same manner as in the above embodiment. When the sprinkler 31 is rotated, the two jets 6a, 6
b, the water discharge inlets 21a, 21b for shower water or the water discharge inlets (arc-shaped lower portions) 22a, 22b for pool water are opposed to each other at the same angle θ and from the rotation center 31c. Obviously, it is sufficient to arrange them on a distance, that is, on the same circumference Dc.

It should be noted that the water discharge inlets 23 to 26 connected to the water discharge outlet of a water shape suitable for discharging water at a small flow rate may be arranged at appropriate positions on the same circumference Dc. However, the water discharge inlets 23 to 26 are arranged so as to be in a positional relationship so as to close the other one of the two outlets 6a and 6b when facing the other.

As described above, in the present invention, the two jet ports on the tip end surface of the watering nozzle body are not limited to being provided on different circles centered on the rotation center of the watering body.
It can also be arranged on the circumference. It should be noted that the type and number of water discharge outlets suitable for large or small flow discharge and the arrangement thereof may be appropriately designed. The nozzle for watering according to the present invention is not limited to those described above, and can be embodied by appropriately changing the design without departing from the gist of the nozzle.

[0032]

According to the nozzle for watering according to the present invention, as is clear from the above description, in a water type where a large flow rate is suitable, such as shower watering and spouting water for reservoir water, two nozzles are used. Water can be supplied through a single jet port in a water form where a small flow rate is suitable, such as straight watering or flat watering. Accordingly, a desired amount of water can be spouted according to the water shape, and a desired watering form can be obtained at an appropriate flow rate.
