Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic horticultural water supply nozzle which is attached to a water storage container such as a so-called plastic bottle and is used by stabbing it into plant growing soil such as a flower pot.

[0002]

2. Description of the Related Art As such a water supply nozzle, as shown in FIG. 5, a mounting portion (61) detachable from a water storage container (P) and a plurality of recesses (53) on an outer peripheral surface are provided. The nozzle body (51) is shaped like a cone with a groove (52) formed, and the water supply hole (55) is opened by arbitrarily pushing through the thin film (54) at the bottom of the recess (53). The water supply nozzle (B) to be made to be known is known (registered utility model No.
No. 3040560). Since the nozzle body (51) is formed in a shape based on a cone, the water supply nozzle (B) can be easily inserted into soil such as a flowerpot. In addition, the thin film (54) at the bottom of the recess (53) is arbitrarily crushed to make the nozzle body (51) communicate with the inside and outside thereof, and the water supply hole (55)
Water supply holes (55) (5
5) The user can arbitrarily select the amount of water supply depending on the number of
This has the advantage that it can be set.

[0003]

However, if such a water supply nozzle (B) pushes through the thin film (54) to open the water supply hole (55), it cannot be closed again. Therefore, although it is possible to increase the water supply once set, it is somewhat difficult to reduce it.

[0004] That is, it is not impossible to set a small amount of water supply by covering a part of the water supply hole (55) with tape or closing it with short and small padding. When the main body (51) is inserted into the soil, the tape may be peeled off, and there is a possibility that there is no longer anything that blocks the water supply hole (55). In the latter case, it is extremely troublesome to close the minute water supply hole (55) with the corresponding small padding. In any case, something that is not originally provided in the nozzle body (51) must be prepared.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to provide an automatic horticultural water supply nozzle capable of arbitrarily changing a water supply amount per unit time. .

[0006]

In order to achieve the above object, an automatic watering nozzle for horticulture according to the present invention has a mounting portion having an air hole and detachable from a water storage container, and a plurality of mounting portions on a peripheral surface. And a conical nozzle body integrally formed with the mounting portion, and a water supply amount adjusting member is mounted in the nozzle body.

The water supply amount adjusting member is made of a so-called sponge, a synthetic resin foam having a high elasticity, such as polyurethane having open cells, and is made of a sponge. The shape and size are not particularly limited, but it is preferable that the shape and the size are larger than the length of the nozzle main body and the cross-sectional area is larger than the opening surface of the nozzle main body.

[0008] The water supply amount adjusting member loaded in the nozzle body forms a water passage when the continuous air bubbles move the water in the water reservoir to the water supply hole of the nozzle body. And
By adjusting the compression when the water supply amount adjusting member is loaded into the nozzle body, the water passage is widened or narrowed, and the water discharge amount from the water supply hole is adjusted.

When the water supply amount adjusting member is such an elastic body, since the nozzle body has a conical shape, the water supply amount adjustment member which is strongly compressed at the time of loading is gradually uncompressed by its elastic restoring force. Attempts to restore the original shape may cause the water passage to widen and fail to maintain the desired water supply. In order to suppress the undesired elastic restoring force of such a water supply amount adjusting member and secure a desired water supply amount, the nozzle body includes a restraining means for restraining the water supply amount adjusting member in the nozzle body. It is desirable to become.

In the case where the restraining means is a projection protruding from the inner surface of the nozzle body and capable of suppressing the elastic restoring force of the water supply amount adjusting member in a direction orthogonal to the axis of the nozzle body, the compressed water supply amount adjusting member is provided. In addition to suppressing the elastic restoring force and maintaining the compressed state appropriately, it also has a function as a reinforcing member for the wall surface of the nozzle body.

In the case where the restricting means is a ring-shaped restricting member detachably fitted to the inner edge of the opening of the nozzle body, the compressed water supply amount adjusting member is pressed down from above, and the maximum amount of the water supply amount adjusting member is reduced. When the one end of the water supply amount adjusting member protrudes into the water storage container from the center hole of the annular high-side member, the center hole of the water supply amount adjusting member can be maintained. The middle part in the vertical direction is compressed and its projected state is maintained, so by adjusting the amount of projection, the amount of compression of the water supply amount adjustment member in the nozzle body is automatically adjusted, and the adjustment of the water supply amount is adjusted. Will be done. It is also possible to use this ring-shaped restraining member and the convex restraining member together.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in FIGS.

The water supply nozzle (A) of this embodiment is made of a relatively soft synthetic resin such as polypropylene, and as shown in FIG. 1, like the conventional water supply nozzle (B), for example, as a soft drink container. A water bottle (P) is attached to the opening of the water container (P), and the water main body (1) of the water supply nozzle (A) is turned upside down with the water container (P). It is used by inserting it into the soil (D). For this purpose, the attachment part (11) has a spiral groove (12) fitted on a spiral ridge (21) provided on the outer peripheral surface of the mouth of the plastic bottle (P) as a water storage container on its inner surface. It is formed in a so-called screw cap type. In addition, on the annular bottom surface (13) near the nozzle body (1) of the mounting part (11),
An air hole (14) is provided.

[0014] The nozzle body (1) is attached to the mounting portion (1).
It is formed in a conical shape whose inner diameter becomes smaller toward the tip (the lower end in use), and is provided with a plurality of water supply holes (2) and (2) on its peripheral surface. … Is drilled. The water supply hole (2) is large enough to allow a tip of a nail, a cone, or the like to pass therethrough, and the user can arbitrarily enlarge the water supply hole (2) (2). It is desirable to be able to.

On the inner wall of the nozzle body (1), there is provided a pair of convex strip restraining members (3) (3) having a plane parallel to the axis of the nozzle body (1). The elastic restoring force in the direction perpendicular to the nozzle body axis of the water supply amount adjusting member (4) composed of sponge packed in
The water supply amount adjusting member (4) can maintain the compressed state, and can restrict the water supply amount adjustment member (4) in the nozzle body (1).

A ring-shaped restraining member (5) having a flange (5a) on its outer periphery is forcibly and removably fitted into the opening of the nozzle body (1), so that a compressed state is formed in the nozzle body. The water supply amount adjusting member (4) packed into the nozzle body can be confined in the nozzle body (1) by suppressing its elastic restoring force. The ring-shaped restraining member (5) is used to freely attach and detach to and from the nozzle body opening.
Is made of a synthetic resin that is slightly softer than the synthetic resin constituting the above.

FIG. 2 shows a state in which the water supply amount adjusting member (4) is completely packed in the nozzle body (1). In this state, the sponge serving as the water supply amount adjustment member (4) is shown. The water channel inside is the narrowest, and the water supply is set to the minimum. From this state, to increase the amount of water supply,
In particular, in order to obtain a desired water supply amount, the ring-shaped restraining member (5) fitted into the nozzle body opening is once removed from the nozzle body (1), and the upper end of the water supply amount adjusting member (4) is connected to the nozzle. It is most reasonable to pull out little by little from the main body (1) and obtain the desired amount of water supply while checking the amount of water supply.

That is, by gradually pulling out the water supply amount adjusting member (4) from the nozzle body (1), the compressed state of the water supply amount adjusting member (4) in the nozzle body (1) is gradually relaxed, and the water supply amount is reduced. This is because the water passage of the quantity adjusting member (4) is gradually expanded. In this case, one end of the water supply amount adjusting member (4) drawn out from the nozzle body (1) is passed through the center hole of the ring-shaped restraining member (5), and the elasticity of the center hole by the ring-shaped restraining member (5) toward the inner edge of the center hole. It is preferable that the ring-shaped restraining member (5) is re-inserted into the nozzle main body opening while being slightly protruded from the ring-shaped restraining member (5) while the restoring force is suppressed. When the water supply amount adjusting member (4) is pulled out to some extent, when checking the water supply amount,
This is because the intermediate portion of the water supply amount adjusting member (4) is restrained by the ring-shaped restraining member (5), and the compressed state of the water supply amount adjusting member (4) in the nozzle body is reliably maintained. FIG.
The water supply amount adjusting member (4) is drawn out of the nozzle body (1), and the intermediate portion thereof is restrained by the ring-shaped restraining member (5) to ensure a constant water supply amount.

[0019]

According to the present invention, as described above, the water supply amount adjusting member is loaded in the nozzle body having the water supply hole on the peripheral surface. The amount of water supplied from the water supply hole can be arbitrarily changed.

In the case where the water supply amount adjusting member is an elastic body such as a sponge having open cells, the strength of the packing when the sponge is loaded into the nozzle body, that is, the strength of the compressed state, can be adjusted. With the simple operation of, the desired water supply amount can be obtained. In addition, the cost increase can be made extremely small, so that it is economical.

When the nozzle body is provided with a restraining means for restraining the water supply amount adjusting member in the nozzle body, the restraining means suppresses the elastic restoring force of the elastic body as the water supply amount adjusting member, Since the compressed state is maintained, the set water supply amount is not unintentionally changed and the desired water supply amount can be supplied stably.

In the case where the restraining means is a projection which is provided on the inner surface of the nozzle body and which can suppress the elastic restoring force of the water supply amount adjusting member in the direction perpendicular to the axis of the nozzle body, the compressed water supply amount adjusting member can be compressed. Not only can the state be surely maintained and a stable amount of water can be supplied, but also the strength of the nozzle body can be improved.

When the restraining means is a ring-shaped member detachably fitted to the inner edge of the opening of the nozzle body, it is easy to adjust the degree of compression of the water supply amount adjusting member in the nozzle body.
