Description

Drip hose {DROPS HOSE}

The present invention relates to a drop hose.

Generally, the drop hose is for watering the crop. These drip hoses are formed at intervals with flow paths having inlets and outlets. The inlet port is connected to the inner passage of the drop hose, and the outlet port is connected to the outside. Water flowing through the inner passage of the drop hose flows into the inlet and flows along the flow path to the outlet. The water discharged to the outlet is fed to the crop. At this time, water is supplied to the crop by dropping at the discharge port or sprayed in the form of a stream of water.

However, when the flow path is finely formed, the flow path is easily blocked by foreign substances such as mold. In the low water pressure part, the peripheral surfaces of the inner passage through which the water passes are stuck together by the water. In the part where the inner passage was stuck, water did not flow into the flow path.

In addition, the drip hose portion in which the flow path is formed is also stuck by water passing through the flow path, thereby blocking the inlet.

The internal passages and flow paths of the drop hoses prevented water from being supplied to the crops.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

Then, a drip hose according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

1 is a perspective view showing a state in which both ends of the resin film constituting the drip hose of the present invention, Figure 2 is a perspective view showing a drip hose formed with a fusion portion in the overlapped both ends shown in Figure 1, Figure 3 is It is a front view which shows the drip hose shown.

First, referring to FIG. 1, in the drop hose according to the present embodiment, a resin film having a predetermined length is formed in a tubular shape. When the resin film is dried in the form of a tube, one end portion 11 and the other end portion 12 of the resin film overlap each other. When the resin film is curled, one end portion 11 is located on the inner side and the bullet end portion 12 is located on the outer side. Accordingly, the outer surface of the resin film one end portion 11 and the inner surface of the carbon end portion 12 face each other. When the one end portion 11 and the carbon end portion 12 face each other, the resin film is formed in a tube 20 in a circle or ellipse form. An inner passage 21 through which water flows is formed in the tube 20.

On the other hand, the degree of overlapping one end portion 11 and the end portion 12 of the resin film may be 1/5 to 2/5 of the diameter of the tube 20. If the one end part 11 and the bullet end part 12 overlap with each other, the part which couple | bonds the one end part 11 and the bullet end part 12 becomes narrow. Since the coupling portion is narrowed, the coupling force between the one end 11 and the bullet end 12 is lowered. And if the degree of overlap of the end portion 11 and the bullet end 12 is 2/5 or more, the coupling portion is increased more than necessary.

Referring to FIGS. 2 and 3, one end portion 11 and one end portion 12 are thermally fused to a portion where the one end portion 11 and the other end portion 12 overlap each other in a state where the one end portion 11 and the other end portion 12 face each other. And combines the end 12. The overlap is heat-sealed at intervals along the length. Accordingly, the fusion portion 30 is formed at the portion where the one end portion 11 and the bullet end portion 12 are overlapped.

The fusion unit 30 includes a pair of first and second horizontal lines 31 and 32 and a pair of connecting lines 33.

The first and second horizontal lines 31 and 32 are spaced apart in the vertical direction and are formed along the longitudinal direction of the tube 20.

The first horizontal line 31 is located on the upper side, and the length may be 78MM to 98MM. When the length of the first horizontal line 31 is 78 mm or less, the fusion portions 30 are densely formed. And if the length of the first horizontal line 31 is 98MM or more, the heat fusion time is increased.

The second horizontal line 32 is separated from the first horizontal line 31 and the length of the second horizontal line 32 may be 84MM to 104MM. When the length of the second horizontal line 32 is less than or equal to 84MM, the fusion portions 30 are densely formed. And if the length of the 2nd horizontal line 32 is 104MM or more, heat welding time will increase.

As such, the centers of the second horizontal line 32 and the first horizontal line 31 are located on the same line. Since the length of the second horizontal line 32 is longer than the length of the first horizontal line 31, and the centers of the second horizontal line 32 and the first horizontal line 31 are located on the same line, both ends of the second horizontal line 32 are provided. Protrudes more than both ends of the first horizontal line 31.

The fusion unit 30 including the first and second horizontal lines 31 and 32 and the pair of connecting lines 33 are formed at intervals along the longitudinal direction of the pipe 20. The fusion portions 30 are formed at intervals so that a predetermined fusion pattern is formed in the tube 20 along the longitudinal direction. The fusion pattern enhances the appearance of the drip hose.

Next, another embodiment of the fusion unit 30 of the present invention will be described with reference to FIG.

4 is a front view showing another embodiment of the welding portion shown in FIG.

Referring to FIG. 4, the fusion unit 30 according to the present embodiment includes first and second portions 36 and 37 and a partial connection line 38.

Fusion portion 30 according to the present embodiment is substantially the same as the embodiment shown in Figure 3 but there is a slight difference in shape. The first and second portions 36 and 37 of the fusion portion 30 according to the present embodiment are spaced apart from each other and are bent in opposite directions. The bent portions of the first and second portions 36 and 37 are connected in a curve. The upper and lower ends of the bent first portion 36 face each other. At this time, the end of the lower end protrudes more than the end of the upper end. The length at which the lower end protrudes more than the upper end may be 2MM to 4MM.

The connecting line 28 connects the first and second parts 36 and 37. The connecting line connects the curve of the first portion 36 and the curve of the second portion 37 at the center.

Since the fusion portion 30 is formed at intervals along the longitudinal direction of the tube 20, there is no adhesion between the adjacent fusion portions 30. The non-stick end 11 and the bullet end 12 may be separated from each other. Accordingly, a flow path portion 40 connected to the inner passage 21 is formed between the adjacent fusion splicing portions 30 that are not stuck.

Next, the flow path unit will be described with reference to FIGS. 3 and 5.

FIG. 5 is an enlarged view of a fusion portion of the drop hose shown in FIG. 3.

Referring to FIGS. 3 and 5, the flow path part 40 is introduced with water flowing along the inner passage 21 of the pipe 20 and discharged to the outside of the pipe 20. Accordingly, the flow path part 40 includes a flow path partition line 41, an inlet port 42, an outlet port 43, a first flow path 44, and a second flow path 45.

The flow path partition line 41 is located between the adjacent welded portions 30. A portion of the flow path division line 41 is located at one side fusion portion 30 'and the other portion of the flow path division line 41 is located at the other side fusion portion 30 ". 41 is disposed between the first horizontal line 31 and the second horizontal line 32. At this time, the flow path partition line 41 is separated from the first horizontal line 31 by a distance of 5.5 mm to 7.5 mm and the second horizontal line 32 The flow path division line 41 is oriented in the direction of the second horizontal line 32. Thus, the flow path division line 41 and the second horizontal line 32 are separated from the flow path division line 41 by a distance of 4MM to 6MM. Narrower than between the first horizontal lines 31.

The end of the portion of the flow path segment 41 is separated from the connecting line 33 of the one side fusion portion 30 'by a predetermined distance, and the end of the other portion of the flow path segment 41 is the connection line 33 of the other side fusion portion 30 ". The distance from the flow path partition line 41 to the connecting line 33 may be 6MM to 8MM.

Since the flow path partition line 41 is formed between the first horizontal line 31 and the second horizontal line 32, the first horizontal line 31 and the second horizontal line 32 of the one-side welding part 30 ′ are formed. One flow path 44 is formed. In addition, a second flow path 45 is formed between the first horizontal line 31 and the second horizontal line 32 of the other welding portion 30 ″.

The first and second flow paths 44 and 45 are connected to one inlet 42 and one outlet 43.

The inlet 42 is positioned between the first fusion spliced portion 30 'and the first horizontal line 31 of the other fusion spliced portion 30 ". The outlet 43 is the one fusion spliced portion 30' and the other fusion spliced portion 30. Located between the second horizontal line 32 of " The inlet port 42 and the outlet port 43 face each other with the passage block line 41 interposed therebetween.

On the other hand, since the distance between the flow path partition line 41 and the second horizontal line 32 is narrower than the distance between the flow path partition line 41 and the first horizontal line 31, the widths of the first and second flow paths 44 and 45 are From the inlet 42 to the outlet 43 becomes narrower.

Inlet 42 is connected to the inner passage 21 of the pipe (20). Accordingly, water flowing along the inner passage 21 may be introduced through the inlet 42. Water introduced into the inlet 42 is dispersed in the first passage 44 and the second passage 45 to flow in the direction of the outlet 43. In this case, since the width of the first and second flow paths 44 and 45 becomes narrower toward the discharge port 43, the speed of the water flowing through the first and second flow paths 44 and 45 may increase.

Since the lengths of the first horizontal line 31 and the second horizontal line 32 are different, the widths of the inlet 42 and the outlet 43 are also different. The width of the inlet 42 is 11MM to 13MM, and the width of the outlet 43 is 5MM to 7MM.

Meanwhile, since the widths of the first and second flow paths 44 and 45 are narrowed from the inlet 42 to the discharge port 43, the speed of the water flowing through the first and second flow paths 44 and 45 increases and the pressure is increased. Will be lowered. In addition, since the width of the discharge port 43 is smaller than the width of the flow path partition line 41 and the connecting line 33, and the width of the second horizontal line 32 and the flow path block line 41, the water discharged to the discharge port 43 at a high speed. Can be sprayed.

Further, since the first and second flow paths 44 and 45 are formed between one inlet 42 and the outlet 43, water flowing into the inlet 42 is blocked through any of the outlets 43. May be discharged. As a result, water can be continuously supplied to the crops.

The first and second flow paths 44 and 45 are bent portions between the connecting line 33 and the flow path partition line 41. Since the connection line 33 is formed in a curve, water flowing in the first and second flow paths 44 and 45 may flow naturally along the curve.

Meanwhile, the flow path portion 40 located between the fusion portion 30 shown in FIG. 4, which is another embodiment of the fusion portion shown in FIG. 3, is substantially the same as the flow path portion 40 shown in FIG. 5, and has the same effect. Have That is, the flow path part 40 of FIG. 4 is also located between the adjacent fusion splicing parts 30, and the flow path partition line 41, the inlet port 42, the discharge port 43, the first flow path 44, and the second flow path Includes 45. The width of the first and second flow paths 44 and 45 is narrower from the inlet 42 to the outlet 43. And the width of the outlet 43 is formed narrower than the width of the inlet (42).

Accordingly, when water flowing along the inner passage 21 of the pipe 20 flows into the first and second flow paths 44 and 45 through the inlet 42, it flows in the direction of the outlet 43. At this time, since the width of the first and second flow paths 44 and 45 is narrowed, the flow rate of water increases. In addition, since the discharge port 43 is formed to be narrower than the width of the first and second flow paths 44 and 45, the water discharged from the discharge port 43 may be injected at a high speed.

In addition, since the first and second flow paths 44 and 45 are formed between one inlet 42 and the outlet 43, the water introduced into the inlet 42 is blocked by any one of the flow paths. Can be discharged through. As a result, water can be continuously supplied to the crops.

Next, with reference to FIGS. 6 to 9, the channel pattern portion 50 forming the channel 53 to prevent the inner passage 21 from being adhered by water will be described.

FIG. 6 is an enlarged view of a portion A shown in FIG. 2, and FIG. 7 is a cross-sectional view showing another embodiment of the channel pattern portion shown in FIG. 6, and FIG. 8 is a state in which the inner surface of the drip hose shown in FIG. 2 is in contact with it. 9 is a cross-sectional view showing a state where the inner surface of the inner passage shown in FIG. 6 is in contact.

6 to 9, the channel pattern part 50 according to the present embodiment includes a horizontal bar 52 and a vertical bar 51. The horizontal bar 52 and the vertical bar 51 are alternately formed at intervals.

The horizontal bars 52 are formed at intervals along the longitudinal direction L of the pipe 20. The vertical bars 51 are positioned between the horizontal bars 52 and are formed in a direction perpendicular to the horizontal bars 52. As the horizontal bar 52 and the vertical bar 51 are formed at intervals, a channel 53 is formed between the horizontal bar 52 and the vertical bar 51. The width of the horizontal bar 52 and the vertical bar 51 is 0.2MM, the length is 2.5MM to 3.5MM. Width and length of the horizontal bar 52 and the vertical bar 51 may vary depending on the diameter of the inner passage (21).

The interval between the adjacent vertical bars 51 is 4MM to 6MM, and the interval between the neighboring horizontal bars 52 is 2MM to 4MM. If the spacing of the vertical bars 51 is 4MM or less, and the spacing of the horizontal bars 52 is 2MM or less, the channel 53 is narrowly formed. On the contrary, if the spacing of the vertical bars 51 is 6MM or more and the spacing of the horizontal bars 52 is 4MM or more, the channel 53 is formed wide. When the channel 53 is formed wide, the surfaces of the channel 53 formed on the surfaces facing each other among the peripheral surfaces of the inner passage 21 adhere to each other.

As shown in FIG. 8, the vertical bar 51 and the horizontal bar 52 may be inclined in the 45 ° direction based on the length direction L of the pipe 20. In other words, the vertical bar 51 and the horizontal bar 52 are repeatedly formed in the diagonal direction with respect to the longitudinal direction (L).

The inclination angle of the vertical bar 51 and the horizontal bar 52 of the channel pattern part 50 with respect to the length direction L of the pipe 20 may be variously formed.

The surface of the inner passage 21 is not adhered by the channel pattern portion 50 including the vertical bars 51 and the horizontal bars 52 forming the channel 53. Even though the inner passage 21 is bonded, water may flow through the water channel 53 formed by the horizontal bars 52 and the vertical bars 51. In addition, since water flows through the channel 53, the inner surface of the inner passage 21 attached by the water pressure may be easily dropped.

Since the channel pattern part 50 is formed on one surface of the resin film, as shown in FIG. 8, the channel pattern part 50 may also be located in the flow path part 40. The end of the end portion 11 is not in contact with the inner surface of the bullet end portion 12 by the channel pattern portion 50. Accordingly, the inlet port 42 is always kept open. Since the inlet port 42 remains open, water flowing along the inner passage 21 may always flow into the inlet port 42.

Therefore, the water flowing through the inner passage 21 by the channel pattern part 50 formed in the flow path part 40 can always be introduced into the inlet 42 and discharged to the outlet 43.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.
