Abstract

The present invention relates to a drip hose, which comprises: a hose main body having outlets formed by penetrating one side portion of a supply flow path; and a decompression liner attached to the inner circumferential surface of the supply flow path to cover the outlets, and having a decompression flow path connecting the supply flow path to the outlets, wherein the decompression liner is attached in a longitudinal direction of the hose main body. In addition, the decompression liner comprises: a body unit having the decompression flow path while being attached to the inner circumferential surface of the hose main body; and a non-attachment type extension unit connected to one side end or both side ends of the body unit, without being attached to the inner circumferential surface of the hose main body. Therefore, when a predetermined location of the non-attachment type extension unit is cut from the hose main body before a hose connector is inserted into the cut location, the non-attachment type extension unit is inwardly folded such that the outer circumferential surface of the hose connector adheres to the inner circumferential surface of the hose main body, thereby preventing leakage.

Description

Drip hose that does not leak when connected after cutting {DRIP HOSE}

In the present invention, after cutting a predetermined part of a drip hose equipped with a pressure reducing liner, when connecting the cut part by inserting the cut part into the hose connector, the cut part of the drop hose is in close contact with the hose connector and there is no minute gap so that no leakage occurs. It is about drip hose.

In general, the drip hose is installed on the ground close to the root of the crop when growing crops, and through the drain hole formed in the drip hose, the discharge hole is formed very fine so that the water inside the hose can be continuously supplied to the ground in small increments. , It means that water is condensed in the discharge hole in the form of droplets and supplied.

In a general hose, the water pressure is high on the supply side, and the water pressure decreases as the distance from the supply side increases.Therefore, the supply of water increases in places where the water pressure is high, and the water supply amount decreases in places where the water pressure is low. However, the drip hose has the advantage of being able to constantly supply a uniform amount of water to all crops regardless of the internal water pressure of the hose.

As a prior art for such a drop hose, there is a registered patent No. 0569225.

The prior art includes an inlet through which water inside the tube (hose) is introduced, a decompression unit for decompressing the introduced water, and a discharge unit for discharging water to the outside of the tube through the decompression unit,

The inlet portion and the depressurization portion are elongated in a concave shape along the upper surface of the decompression liner, and the decompression liner is attached to the inner side of the tube along the entire length direction of the tube.

However, when the length of these drip hoses is correct at the time of initial installation, or when the hose is damaged, water source replacement, length adjustment, etc. are required, a part of the hose must be cut and connected by inserting it into a nibble-shaped hose connector. Since the pressure-sensitive liner is attached to the side and protrudes, when the hose connector is inserted into the cut portion of the drop hose, there is a problem in that water leakage occurs due to a fine gap that occurs depending on the thickness of the pressure-sensitive liner.

That is, as shown in Fig. 1, the thickness of the pressure reducing liner (L) is relatively thick compared to the thin hose, and accordingly, when the hose connector is inserted into the cut portion of the drop hose (H), the pressure reducing liner (L) is Due to the thickness, there is a problem in that water leakage occurs due to a fine gap between the hose connector and the hose.

Accordingly, the present invention was devised to solve the above problems,

Even if the drip hose is used after cutting, its object is to provide a drip hose that can prevent leakage of water at the cutting site by preventing the occurrence of a fine gap between the drip hose and the hose connector.

In order to achieve the above object, the drop hose according to the present invention,

In the drip hose,

The pressure reducing liner includes a body portion attached to the inner circumferential surface of the hose body while having the pressure reducing flow path, and a non-attached extension portion connected to one or both ends of the body portion and not attached to the inner circumferential surface of the hose body,

When the hose connector is inserted into the cut portion after cutting a predetermined position of the non-attached extension part in the hose body, the outer circumferential surface of the hose connector is in close contact with the inner circumferential surface of the hose body while the non-attached extension part is folded inward, and leakage It is characterized in that it does not occur.

And the drip hose according to the present invention,

The non-attached extension portion is characterized in that the thickness is smaller than that of the body portion.

Furthermore, in the drip hose according to the present invention,

The non-attached extension portion is characterized in that the inner side is connected in a straight line with the inner side of the body portion, and a step portion is formed between the hose body and the non-attached extension portion.

Also in the drop hose according to the present invention,

The hose body and the pressure reducing liner are both made of synthetic resin, and the body portion is attached to the hose body in a heat-pressing manner.

The drip hose according to the present invention,

There is an unattached extension part that is separated by a decompression liner not attached to the hose body at a predetermined interval along the length of the hose body.When the hose connector is inserted into the cut part after cutting a predetermined position of the unattached extension part, the unattached extension As the part is folded inward, the hose body and the hose connector are in close contact with each other, preventing leakage of water due to the fine gap.

In the detailed description and claims of the invention, unless otherwise specified, directions are specified and described in accordance with this standard.

Hereinafter, a drop hose according to the present invention will be described with reference to the accompanying drawings.

The present invention is as shown in Figures 2 to 4,

A hose body H having discharge holes 11 formed through one side of the supply passage 10; And a decompression liner (L) attached to the inner circumferential surface of the supply passage (10) to cover the discharge holes (11) and having a decompression passage (21) connecting the supply passage (10) and the discharge holes (11). Including, it relates to a drop hose to which the pressure reducing liner (L) is attached in the longitudinal direction of the hose body (H),

The pressure reducing liner (L) is connected to the body portion (20) attached to the inner circumferential surface of the hose body (H) while having the pressure reducing passage (21), one or both ends of the body portion (20). Including a non-attachment extension 22 that is not attached to the inner circumferential surface of the hose body (H),

When the hose connector 30 is inserted into the cut portion after cutting a predetermined position of the non-attached extension part 22 in the hose body H, the hose connector is folded inwardly. It is characterized in that the outer circumferential surface of (30) is in close contact with the inner circumferential surface of the hose body (H), so that no water leakage occurs.

First, a schematic description of the configuration of the decompression liner (L),

A decompression flow path 21 formed of a side wall portion 23 is provided along the length direction of the body portion 20, and a water supply hole is spaced apart from the side wall portion 23 at a predetermined distance at one end of the decompression flow path 21. A protrusion 25 forming the 24) is provided, and a discharge part 26 is provided at the other end of the decompression flow path 21 and surrounded by the side wall 23 and the other end thereof is sealed,

The decompression flow path 21, the water supply hole 24, and the discharge part 26 are formed in a concave shape in which the upper surface of the body part 20 is opened.

This pressure reducing liner (L) is attached to the inner circumferential surface of the hose body (H) to form a drop hose, and a part of the hose body (H) at the location where the discharge part 26 is located is drilled or cut to open the discharge hole 11 Formed.

When the drip hose is connected to a water source to supply water, water flowing along the supply flow path 10 of the hose body H flows into the water supply hole 24 and then decompresses while passing through the pressure reduction flow path 21. After being collected in the discharge part 26 in a state that is collected, a small amount is discharged to the outside of the drop hose through the discharge hole 11, and a small amount of water is supplied to the ground, etc.

However, the specific structure (decompression flow path 21, water supply hole 24, and discharge unit 26) of the body part 20 described in this specification is an example for illustration, and the previously described decompression liner (L) and It is sufficient if members of the same function are attached to the inner circumferential surface of the hose in a protruding form, and the specific structure for implementing the decompression function may vary, and the interpretation of the rights of the present invention should not be limited due to these differences.

As previously described, the conventional drip hose with a pressure-sensitive liner having an internal protrusion structure has the pressure-sensitive liner (L) long attached over the entire length of the hose, as described in the background art. When using the hose after cutting, a height difference is formed on the inner circumferential surface of the hose body (H) due to the thickness of the pressure reducing liner (L), and therefore, when a hose connector 30 such as a nibble type is inserted into the cut part of the drop hose. As a fine gap was formed between the hose body (H) and the hose connector (30), water leakage occurred.

Accordingly, the present invention allows the outer circumferential surface of the hose connector 30 to be in close contact with the inner circumferential surface of the drip hose even if the drip hose is cut through the non-attached extension part 22 and then inserted into the hose connector 30 to prevent leakage. .

That is, if the non-attachment extensions 22 are provided at regular intervals along the longitudinal direction of the hose body H, the ends of the non-attachment extensions 22 are connected to the hose body H when the corresponding part is cut. Completely separate,

Therefore, if the hose connector 30 is inserted after opening the non-attached extension part 22 inward at a predetermined interval, the hose connector 30 pushes the non-attachment extension part 22 inward to fold it, and the non-attachment extension part There is no separate protruding structure on the inner circumferential surface of the hose body (H) where (22) was,

After inserting the hose connector 30 into the cutting part of the drip hose and tightening the pressure port 31, the watertight protrusion 32 of the hose connector 30 is in close contact with the inner circumferential surface of the hose main body There is no gap, so there is no leakage.

At this time, in this specification, a hose connector 30 that is tightened with a pressure port 31 in a nibble shape and connected to a hose has been described as a representative, but there is no limitation on the specific type, structure, or shape of the hose connector 30 (as an extreme example. It is also possible to replace the hose connector 30 with a pipe by inserting a general pipe into the cut part of the drip hose and then wrapping it with a cable tie or wire.)

In this case, the non-attached extension part 22 is characterized in that the thickness is smaller than that of the body part 20.

That is, by making the thickness of the non-attached extension part 22 thinner compared to the body part 20 (for example, when the body part 20 has a thickness of 1 mm, the non-attachment extension part 22 is 0.5 mm) It has the thickness of.), it makes it possible to more easily open the non-attached extension part 22 after cutting the dropping hose.

Further, the non-attached extension part 22 has an inner side connected in a straight line with the inner side of the body part 20, so that a step portion 22a is formed between the hose body H and the non-attachment extension part 22. It is characterized by being formed.

When the non-attached extension part 22 is connected in the same line with the inner surface of the body part 20, the gap part by the step part 22a is naturally formed when the drop hose is cut. Therefore, the user can use a fingernail or other The non-attachment extension 22 can be more easily opened (or folded) by inserting a tool.

This is because, as described above, not only the hose body H, but also the body portion 20 and the non-attached extension portion 22 are very thin, and the diameter of the hose body H itself is not large, the body portion 20 ) And the thickness difference of the non-attached extension part 22 and the stepped part 22a are formed artificially to form a fine gap, so that the non-adhering extension part 22 can be more easily opened.

In addition, even if the non-attached extension part 22 is not artificially opened or folded, if the hose connector 30 is inserted into the cut part of the dropping hose, the non-attached extension part 22 is moved inward by the pressure of the hose connector 30. Since it is folded naturally, it is possible to make the connection work more convenient after cutting the drip hose.

In addition, the hose body (H) and the pressure reducing liner (L) are both made of synthetic resin, and the body portion 20 is attached to the hose body (H) in a heat-pressing manner.

In the present specification, the heating compression method refers to the concept of inserting and inserting the pressure reducing liner (L) into the supply passage (10) of the hose body (H), and then heating and pressing the upper surface of the hose body (H) with a pressing member such as a roller. As such, the specific structure of the pressing member may vary.

In particular, the present invention is connected so that the non-attached extension portion 22, which is thinner than the body portion 20, is formed with a step portion 22a between the hose body H, and the hose body in which the pressure reducing liner (L) is inserted ( When the upper surface of H) is simply heated and compressed, only the body part 20 in contact with the inner circumferential surface of the hose body (H) is attached to the hose body (H), and the non-adhesive extension part separated from the hose body (H) ( Since 22) is not naturally attached to the hose body (H), it is possible to more easily manufacture the drip hose according to the present invention only by adjusting the height of the heating and pressing.

Further, the hose main body (H) is characterized in that the cutting boundary line 12 is marked on the outer circumferential surface at a position corresponding to both ends in the longitudinal direction of the non-attached extension part 22.

Therefore, even if the hose body (H) is opaque, the user can easily identify the position of the non-attached extension part 22 through the cutting boundary line 12, and taking into account the fastening direction of the hose connector 30, both cutting boundary lines ( By cutting one of the 12) or a predetermined position between them, the hose connection operation can be performed more easily.

Meanwhile, in the present invention, since the non-attachment extension part 22 is connected to form a stepped part 22a, the user can artificially open the non-attachment extension part 22 or naturally contact it by inserting the hose connector 30. However, due to the very thin thickness, the non-attachment extension part 22 is bent and twisted without being safely folded into the inside of the hose body H, so that a part of the body part 20 may fall from the hose body H.

Accordingly, the present invention introduces a structure in which the non-attachment extension 22 can be more easily folded naturally when the hose connector 30 is inserted, as shown in FIG. 5.

Specifically, the pressure-sensitive liner (L) is configured by connecting the non-attached extension portion 22 between the body portion 20 on both sides,

The non-adherent extension part 22 consists of a bent part 22S bent in a'U' shape so as to exert an elastic force in a direction in which both body parts 20 are adjacent,

When the hose body (H) cuts a predetermined position of the non-attachment extension part 22, the non-attachment extension part 22 cut with respect to the hose body H is opened in a streamlined form. do.

That is, since the body part 20 is attached over the entire length of the hose body H, the non-attached extension part 22 between the body parts 20 is artificially bent to form a'U' shape. The bent portion 22S is formed by imparting an elastic force using the properties of the resin itself.

The pressure-sensitive liner (L) having such a bent portion (22S) is naturally unattached when inserted into the hose body (H), the non-adhesive extension (22) is then heated and compressed. A decompression liner (L) is attached while completely unfolding in a'-' shape.

And when the location where the non-adherent extension part 22 is located is cut, the non-adherent extension part 22 naturally opens as it returns to its original'U' shape due to the action of the elastic force applied during initial molding. The unattached extension 22 is folded more easily and naturally by the user directly or through the insertion of the hose connector 30, thereby preventing the above problems from occurring.

In the above description of the present invention, a drop hose has been mainly described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and substituted by those skilled in the art, and such modifications, changes and substitutions fall within the protection scope of the present invention. Should be interpreted as.
