Description

Technical Field

[0001] The present invention belongs to the technical field of water-saving irrigation, and particularly relates to an irrigation water hose with a prefabricated quick-connect water-saving structure. Background Art

[0002] With the change of the global climate, the shortage of water resources is facing an increasingly severe situation. Among them, agricultural irrigation consumes a large amount of fresh water resources. At present, in agricultural irrigation, the waste of water resources is still relatively serious. In this context, reducing irrigation water waste has become an important way to alleviate the shortage of agricultural water resources.

[0003] Due to its characteristics such as being rollable, light in weight, and convenient to use, the water hose has a wide range of applications in the field of agricultural irrigation. In actual applications, the water hose is usually used as the main water delivery pipeline, and branch pipelines are laid around the main water delivery pipeline. The branch pipelines can be hard water pipes or hoses. Water sources are diverted from the main water delivery pipeline to the branch pipelines, and several spray heads are installed on the branch pipelines for irrigation. Compared with traditional watering and flooding methods, the utilization rate of water resources can be greatly improved. Among them, a water-saving valve is used to connect the main water delivery pipeline and the branch pipeline, and the flow of water in the branch pipeline is controlled by the opening and closing of the water-saving valve.

[0004] The three-way water-saving valve is a commonly used one, usually composed of a base and a valve body. The base is installed on the water hose. The existing valve body and base of the three-way water-saving valve are generally connected by a threaded structure. The threaded structure has the following disadvantages in the use process: when tightening the valve body, the degree of tightening varies from person to person, and this difference will affect the angle of the valve body interface after tightening. The main water delivery pipeline and the branch pipeline are generally laid in advance. When the angle of the valve body interface is not fixed, it will affect the connection with the branch pipeline. Especially when the branch pipeline is a hose, it may cause the hose at the connection to bend, affecting water output. On this basis, some people in the relevant technical fields have also proposed to use a clamping method to realize the connection between the valve body and the base to fix the valve body interface. However, the reliability and the convenience of use still need to be improved.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of implication that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] The purpose of the present invention is to provide an irrigation water hose with a prefabricated quick-connect water-saving structure, so as to overcome the defects in the above-mentioned prior art.

[0007] To achieve the above object, the present invention provides an irrigation water hose with a prefabricated quick-connect water-saving structure, which includes an irrigation water hose and a quick-connect water-saving structure.

[0009] Further, as a preference, the semi-closed interval formed by the annular outer cylinder, the annular inner cylinder and the bottom plate is a plug-in area. The locking structure is located in the plug-in area.

Detailed Embodiment

[0035] The following describes the detailed embodiment of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the detailed embodiment.

[0036] The following gives a brief overview of one or more aspects to provide a basic understanding of these aspects. This overview is not an exhaustive survey of all contemplated aspects, and is neither intended to identify the key or decisive elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description to follow.

[0037] Embodiment 1: As Figures 1 - 12 shown, an irrigation hose with a prefabricated quick - connection water - saving structure includes an irrigation hose 3 and a quick - connection water - saving structure. The quick - connection water - saving structure includes a valve seat 1 and a valve body 2 that is mated with the valve seat 1. The valve seat 1 is welded to the irrigation hose 3. The valve seat 1 includes a bottom plate 101. An annular outer cylinder 102 and an annular inner cylinder 103 are provided on the bottom plate 101. A locking structure 4 is provided between the annular outer cylinder 102 and the annular inner cylinder 103. The valve body 2 is provided with an insertion part 201, and the insertion part 201 is provided with an elastic check part 202. When the insertion part 201 is inserted between the annular outer cylinder 102 and the annular inner cylinder 103 and then rotated until the elastic check part 202 cooperates with the locking structure 4, it is locked.

[0038] In this embodiment, as a specific solution, the semi-closed area formed by the annular outer cylinder 102, the annular inner cylinder 103, and the bottom plate 101 is the insertion area 104. The locking structure 4 is located in the insertion area 104. When the insertion part 201 of the valve body 2 is inserted into the insertion area 104 and then rotated until the elastic check part 202 cooperates with the locking structure 4, it is locked.

[0039] In this embodiment, as a specific solution, the locking structure 4 includes a first limiting part 105 arranged on the inner wall of the annular outer cylinder 102 and a second limiting part 106 arranged on the outer wall of the annular inner cylinder 103. When the elastic check part 202 cooperates with the first limiting part 105 and the second limiting part 106 simultaneously, it is locked.

[0040] In this embodiment, as a more specific solution, the first limiting part 105 is composed of a first convex block 1051 arranged in the circumferential direction on the inner wall of the annular outer cylinder 102 and a second convex block 1052 perpendicular to the first convex block 1051. The first convex block 1051 and the second convex block 1052 are of an integral structure and are distributed in an overall L shape, and are used for axially and rotationally limiting the elastic check part 202; more specifically, the second convex block 1052 extends from the inner wall of the annular outer cylinder 102 to the inner wall of the annular inner cylinder 103 and the bottom plate 101.

[0041] In this embodiment, as a more specific solution, the second limiting part 106 is composed of an outer inclined surface 1061 arranged on the outer wall of the annular inner cylinder 103 and a check groove 1062 arranged on the outer inclined surface 1061. The outer inclined surface 1061 extends from the outer wall of the annular inner cylinder 103 to the bottom plate 101, and its circumferential length is greater than the length of the first convex block 1051.

[0042] In this embodiment, as a specific solution, the elastic check part 202 includes a raised piece 2021 arranged on the outer wall of the insertion part 201, and the raised piece 2021 extends below the bottom of the insertion part 201; a check convex block 2022 is arranged on the inner wall of the raised piece 2021; after the insertion part 201 of the valve body 2 is inserted into the insertion area 104 and then rotated until the first convex block 1051 and the second convex block 1052 respectively catch the raised piece 2021 from the top and one side of the raised piece 2021 (as shown at A and B in Figure 7 ), at the same time, the raised piece 2021 catches the outer inclined surface 1061, and the check convex block 2022 catches into the check groove 1062.

[0043] In this embodiment, as a specific solution, both the valve seat 1 and the valve body 2 are integrally injection-molded structures. Since the raised piece 2021 extends below the bottom of the insertion part 201, the raised piece 2021 has an elastic force in the radial direction of the insertion part 201, enabling the raised piece 2021 to tightly hold the annular inner cylinder 103. When thermal expansion occurs in hot weather, due to its certain elastic force, it will not get stuck due to thermal expansion during insertion and rotation.

[0044] In this embodiment, as a specific solution, the bottom of the insertion part 201 is designed with a chamfer. When the insertion part 201 is inserted into the insertion area 104, this chamfer can tightly hold the outer wall of the annular inner cylinder 103.

[0045] In this embodiment, there are a pair of locking structures 4, and the pair of locking structures 4 are symmetrically distributed about the center; a third limiting part 5 is further provided between the pair of locking structures 4, and the third limiting part 5 is used to limit the displacement of the insertion part 201 during reverse rotation.

[0046] In this embodiment, as a more specific solution, the third limiting part 5 is a reinforcing rib structure provided on the inner wall of the annular outer cylinder 102 or the outer wall of the annular inner cylinder 103. The gap between this reinforcing rib structure and the first convex block 1051 is the insertion preset area 107. The outer inclined surface 1061 of the second limiting part 106 extends to the insertion preset area 107. When the insertion part 201 of the valve body 2 rotates reversely from the locked state to the insertion preset area 107, due to the certain elastic force of the raised piece 2021, it can tightly hold the outer inclined surface 1061 of the second limiting part 106, and the third limiting part 5 limits the raised piece 2021 within the range of the insertion preset area 107. Therefore, without a certain external force, the insertion part 201 will not become loose from the valve body 1.

[0047] In this embodiment, as a specific solution, when the insertion part 201 rotates from the insertion preset area 107 to the locking position, it is about 30 - 40 degrees, which can achieve quick insertion. More specifically, when assembling the valve body 2 and the valve seat 1, insert the insertion part 201 of the valve body 2 into the insertion preset area 107, and turn the valve body 2 in the direction of the first limiting part 105 and the second limiting part 106, then the insertion part 201 can be turned to the locking position, and the turning angle is about 30 - 40 degrees. It should be noted that it cannot be inserted in other areas because the third limiting part 5 is provided, and the third limiting part 5 prevents the downward insertion action of the insertion part 201. In addition, within the insertion area 104, the length of the gap in the area of the third limiting part 5 away from the first limiting part 105 and the second limiting part 106 is less than the length of the insertion part 201, so that the insertion of the insertion part 201 can be restricted, thereby limiting the insertion position of the insertion part 201 to the insertion preset area 107. Further, more specifically, only the insertion preset area 107 can meet the insertion space of the insertion part 201, and the insertion part 201 cannot be smoothly inserted in other areas. The third limiting part 5 limits the insertion area to a very small range, which can not only reduce the risk of the insertion part 201 becoming loose (preventing the valve body 2 and the valve seat 1 from becoming loose), but also improve the realization of quick assembly and the assembly efficiency.

[0048] In this embodiment, as a specific solution, the third limiting part 5 can also serve as a reinforcing rib between the annular outer cylinder 102 and the annular inner cylinder 103.

[0049] In this embodiment, as a more specific solution, the annular outer cylinder 102 is also provided with a viewing window 108, and the position of the viewing window 108 corresponds to the position of the first limiting part 105. The viewing window 108 can be used as an indication window for the insertion part 201 to rotate in place, and can also be used as a heat release window for the raised piece 2021 during thermal expansion, so that the insertion part 201 can be normally rotated for quick disassembly and assembly during thermal expansion. This is because in agricultural applications, it is inevitable to have the problem of thermal expansion in the hot summer, and it is difficult to assemble the ordinary structure during thermal expansion.

[0050] In this embodiment, as a specific solution, the annular outer cylinder 102 and the annular inner cylinder 103 extend to the back surface of the bottom plate 101 to ensure that the bottom plate 101 together with the annular outer cylinder 102 and the annular inner cylinder 103 will not bulge due to excessive water pressure after the irrigation water belt 3 is filled with water.

[0051] In another preferred embodiment, the height of the annular inner cylinder 103 is greater than the height of the annular outer cylinder 102; more specifically, the height of the annular inner cylinder 103 is about 1.5 to 2 times that of the annular outer cylinder 102. In this way, when the insertion part 201 is inserted between the annular inner cylinder 103 and the annular outer cylinder 102, the valve seat 1 and the valve body 2 will not easily become loose without external force; the height of the annular inner cylinder 103 should not be too high either, as it will affect the water outlet of the bypass pipe 205 of the valve body 2.

[0052] In this embodiment, as a specific solution, an annular sealing platform 203 is provided on the inner wall of the valve body 2, and the annular sealing platform 203 presses on the mouth of the annular inner cylinder 103.

[0053] In this embodiment, as a more specific solution, a sealing part 109 extending towards the center direction is further provided at the mouth of the annular inner cylinder 103, and the mouth of the sealing part 109 extends beyond the mouth of the annular inner cylinder 103, presenting a structure where the sealing part 109 protrudes from the annular inner cylinder 103; the bottom of the annular sealing platform 203 on the inner wall of the valve body 2 is matched and pressed against the mouth of the annular inner cylinder 103 and the sealing part 109 to achieve sealing between the two.

[0054] In this embodiment, as a more specific solution, a groove structure 110 is further provided between the mouth of the annular inner cylinder 103 and the sealing part 109, and a sealing protrusion 204 is provided at the bottom of the annular sealing platform 203 on the inner wall of the valve body 2. When the sealing protrusion 204 is located in the groove structure 110, sealing gaps 111 are left on the inner and outer sides and the bottom of the sealing protrusion 204 in the groove structure 110. These sealing gaps 111 are used as a buffer space when the sealing protrusion 204 expands due to heat; at the same time, these sealing gaps 111 can also be used as a buffer space for water pressure release.

[0055] In this embodiment, as a more specific solution, the valve body 2 is provided with a bypass pipe 205 and a valve cover 6 for controlling the bypass pipe 205; the valve cover 6 includes an inner cover 601 and an outer cover 602. The valve cover 6 covers the valve body 2, where the inner cover 601 is located on the inner wall of the valve body 2 and the outer cover 602 is located on the outer wall of the valve body 2, and the inner cover 601 presses on the annular sealing platform 203.

[0056] In this embodiment, as a more specific solution, the inner cover 601 is provided with a pipeline channel 603, and by rotating the valve cover 6, the pipeline channel 603 is aligned with the bypass pipe 205; an annular groove structure 206 is provided above the annular sealing table 203, and the end of the inner cover 601 is inserted into the annular groove structure 206; the inner cover 601 and the annular inner cylinder 103 press the annular sealing table 203 from above and below respectively. In addition to achieving a good self-sealing effect, the reliability of the overall structure can be improved; more specifically, when impacted by water flow, since the inner cover 601 and the annular inner cylinder 103 press the annular sealing table 203 from above and below respectively, the valve seat 1, the valve body 2 and the valve cover 6 form a tightly combined overall structure. Especially when the inner cover 601 is located in the annular groove structure 206, there will be no problems such as loosening due to the impact of water flow. Under the impact of water flow, the combination between the valve seat 1, the valve body 2 and the valve cover 6 becomes even tighter.

[0057] In this embodiment, as a more specific solution, the valve body 2 is provided with a pair of buckle structures 207, the outer cover 602 catches the outside of the buckle structures 207, and the buckle structures 207 catch the inner cover 601.

[0058] In this embodiment, as a more specific solution, the outer wall of the inner cover 601 has a stepped structure 604, and the buckle structures 207 are stuck at the stepped structure 604, so that the buckle structures 207 can clamp the inner cover 601 tightly, and the structure is more reliable after the valve cover 6 and the valve body 2 are assembled.

[0059] In this embodiment, as a specific solution, a hose quick connection structure 7 is further provided on the bypass pipe 205.

[0060] In this embodiment, as a more specific solution, the outer wall of the end of the bypass pipe 205 is a conical surface structure, and a plurality of conical protrusions are provided on the conical surface structure; the hose quick connection structure 7 is sleeved on the bypass pipe 205 and can slide on the outer wall of the bypass pipe 205; after the bypass pipe 205 is connected to the hose, the hose quick connection structure 7 is pulled towards the mouth of the bypass pipe 205, so that the hose quick connection structure 7 clamps tightly from the outside of the hose.

[0061] In this embodiment, as a more specific solution, the hose quick connection structure 7 includes a connection main body 701 and a plurality of connection elastic pieces 702 at the tail of the connection main body 701. A plurality of elastic piece protrusions 703 are provided on the inner wall of the connection elastic pieces 702. After the hose is docked with the bypass pipe, the connection elastic pieces 702 and the connection main body 701 clamp the hose; the connection elastic pieces 702 have elastic force in the circumferential direction, so they can adapt to the clamping and fixing of hoses with different thicknesses.

[0062] In this embodiment, as a more specific solution, the taper of the clamping body 701 is greater than that of the bypass pipe 205. After the clamping structure 7 clamps the hose, it will not be tightly clamped at the mouth of the hose and the bypass pipe 205, and thus will not affect the water output of the hose.

[0063] In this embodiment, as a specific solution, a hose limiting structure 208 is further provided on the bypass pipe 205.

[0064] In this embodiment, the irrigation hose 3 is a flexible hose, which can be a nylon flexible hose or a composite flexible hose of polyethylene PE and nylon PA; the valve seat is welded above the irrigation hose 3.

[0065] In this embodiment, the valve body 2 on the irrigation hose 3 can also be replaced with other structures. This structure leads out water flow as a joint, which can be a quick-connect joint, etc. This structure also has a square base, and the square base is welded to the irrigation hose.

[0066] The working principle of the present invention is as follows: The bottom plate 101 of the valve seat 1 is welded to the irrigation hose 3 as a whole. The insertion part 201 of the valve body 2 is inserted into the insertion preset area 107, and the valve body 2 is rotated in the direction towards the first limiting part 105 until it stops when the second convex block 1052 restricts the insertion part 201. At this time, the first convex block 1051 clamps the raised piece 2021 from the outer top of the raised piece 2021, and at the same time, the inner wall of the raised piece 2021 clamps the outer inclined surface 1061, and the check convex block 2022 is stuck into the check groove 1062 to be in a locked state; a hose is connected to the bypass pipe 205 of the valve body, and the water flow can be controlled by rotating the valve cover 6.

[0067] The present invention has the following beneficial effects: The present invention can realize the quick insertion of the valve body and the valve seat. Compared with the threaded connection, the insertion efficiency can be improved, and the position of the valve body is fixed when the insertion is locked because the positions of the first limiting part, the second limiting part and the elastic check part are fixed; When the valve body of the present invention is inserted into the valve seat, the insertion part of the valve body is inserted into the insertion preset area and rotated 30 - 40 degrees until the locking structure locks, and quick insertion can be realized; The first limiting part and the second limiting part of the present invention respectively limit the insertion part from the inside and the outside, and the insertion part is in a concealed state after being locked. While ensuring the insertion reliability, it can avoid the valve body from loosening due to operations such as accidental touching; The present invention is provided with a third limiting part, and the annular inner cylinder is relatively high. During the use process, even if the valve body is misoperated and rotated in the reverse direction, the valve body will not loosen from the valve seat without external force because on the one hand, there are partial outer inclined surfaces in the insertion preset area, and the insertion part has a certain clamping force through the outer inclined surfaces, and on the other hand, the relatively high inner cylinder also makes it difficult for the valve body to loosen; The present invention is provided with an annular sealing platform, which can also have a good self-sealing effect without other sealing structures; The present invention also provides a sealing portion at the mouth of the annular inner cylinder, which can achieve a good sealing effect when cooperating with the annular sealing platform. And because the sealing portion is higher than the mouth of the annular inner cylinder, under the impact of water pressure, the sealing portion is pressed towards the direction of the annular inner cylinder, making its cooperation with the annular sealing platform closer, thereby improving the sealing performance; on this basis, the sealing gap also has a certain pressure release space, which can bear higher water pressure and has better safety; The annular sealing platform provided by the present invention can also be used as a diversion structure to reduce the turbulence of the irrigation water belt and make the water flow into the bypass pipe more smoothly; The inner cover of the valve cover and the annular inner cylinder of the valve seat of the present invention respectively press the annular sealing platform from above and below, and the reliability and sealing performance of the overall structure are better; The present invention is provided with a hose quick-connection structure. After a hose is connected to the bypass pipe, the hose can be quickly locked through the hose quick-connection structure, which is convenient to use; The hose quick-connection structure of the present invention is provided with a clamping elastic sheet, and the taper of the clamping main body is greater than the taper of the bypass pipe. The hose can be clamped from the tail through the clamping elastic sheet, which can be applicable to hoses of various thicknesses, and the interface between the hose and the bypass pipe will not be overly squeezed to affect water outflow.
