Description

A flexible elastomer plastic high-pressure washer water pipe Technical Field

[0001] This utility model belongs to the field of high-performance water pipe technology, specifically relating to a flexible elastomer plastic high-pressure cleaning machine water pipe. Background Technology

[0002] High-pressure washers are widely used in various fields such as industrial cleaning, building maintenance, agricultural irrigation, and household cleaning due to their efficient and fast cleaning capabilities. As a core component of high-pressure washers, the water hose bears the responsibility of delivering high-pressure water flow, and its performance directly affects cleaning efficiency and the lifespan of the equipment. However, traditional high-pressure washer water hoses are mostly made of rigid or semi-rigid materials. While this ensures water pressure transmission to a certain extent, it faces many challenges in practical applications.

[0003] Traditional high-pressure water pipes are prone to breakage under high pressure or tensile force due to the rigidity of their materials. This not only affects the continuity of cleaning operations but may also create safety hazards. Furthermore, in complex and variable working environments, such as when cleaning irregular surfaces or navigating around obstacles, water pipes often need to withstand excessive bending. Traditional materials in these situations are prone to permanent deformation, leading to obstructed water flow, significantly reduced cleaning effectiveness, or even complete loss of functionality. Summary of the Invention

[0004] The purpose of this utility model is to provide a flexible elastomer plastic high-pressure cleaning machine water pipe that overcomes the shortcomings of the prior art. By setting a braided layer and an axis inside the water pipe, the stress and strain distribution of the water pipe is more uniform when it is under pressure, reducing local stress concentration and reducing the risk of breakage.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A flexible elastomer plastic high-pressure cleaner water pipe includes a wear-resistant layer, a braided layer, an inner tube, and an axis. The braided layer is tightly attached to the outer wall of the inner tube, and the wear-resistant layer covers the outside of the braided layer. One or more axes are provided along the length of the inner tube and are located on the outside of the inner tube.

[0007] Furthermore, the braided layer is made of plain weave of warp and weft yarns, and both the warp and weft yarns are formed from multifilaments of polyester fiber, nylon fiber, aramid fiber and spandex fiber.

[0008] Furthermore, the axis is positioned between the warp and weft threads and is woven together with the warp and weft threads.

[0009] Furthermore, the axis is positioned between the braided layer and the inner tube, and the axis is in close contact with the outer wall surface of the inner tube.

[0010] Furthermore, the axis is straight, spiral or braided, and the axis (4) is made of polyester fiber or soft fiber thread.

[0011] Furthermore, both sides of the braided layer are coated with an adhesive layer, and the braided layer is connected to the wear-resistant layer and the inner layer respectively through the adhesive layer.

[0012] Furthermore, the inner tube (3) is made of TPU or PVC elastomer material hose, and the wear-resistant layer (1) is made of high temperature resistant PBT material.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention utilizes an axis that can withstand most of the tensile, compressive, and bending loads, reducing the stress on the pipe material and thus improving the overall load-bearing capacity of the water pipe.

[0015] This invention effectively restricts the radial expansion and axial contraction of the water pipe under pressure through the braided layer, ensuring the dimensional stability and shape accuracy of the water pipe and extending the service life of the high-pressure pipe.

[0016] This invention enables water pipes to have a more uniform distribution of stress and strain when subjected to pressure, reducing local stress concentration and decreasing the risk of rupture. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] As shown in Figures 1 and 2, this embodiment discloses a flexible elastomer plastic high-pressure cleaner water pipe, including a wear-resistant layer 1, a braided layer 2, an inner tube 3, and an axis 4. The braided layer 2 is tightly attached to the outer wall of the inner tube 3, and the wear-resistant layer 1 covers the outer side of the braided layer 2. An axis 4 is provided along the length direction of the inner tube 3, and the axis 4 is located on the outer side of the inner tube 3.

[0024] To limit the deformation of the water pipe, the braided layer 2 is made of plain weave of warp and weft threads, both of which are formed by multifilaments of polyester, nylon, aramid, and spandex fibers. The braided layer 2, made of warp and weft threads, covers the outside of the inner pipe 3, making the stress and strain distribution of the water pipe more uniform.

[0025] To limit the position of axis 4, axis 4 is set between the warp and weft lines and is woven together with the warp and weft lines.

[0026] In order to tightly connect the braided layer 2, both sides of the braided layer 2 are coated with an adhesive layer, and the braided layer 2 is connected to the wear-resistant layer 1 and the inner layer respectively through the adhesive layer.

[0027] In order to improve the performance of the water pipe, the inner pipe (3) is made of TPU or PVC elastomer material hose, and the wear-resistant layer (1) is made of high temperature resistant PBT material, or other high polymer high temperature resistant and wear-resistant elastomer materials.

[0028] During use, axis 4 can withstand most of the tensile, compressive and bending loads, reducing the stress on the pipe material and thus improving the overall load-bearing capacity of the water pipe; braided layer 2 effectively restricts the radial expansion and axial elongation of the water pipe under pressure, ensuring the dimensional stability and shape accuracy of the water pipe and extending the service life of the high-pressure pipe; when the high-pressure water flows through the water pipe, the stress and strain distribution of the water pipe under pressure is more uniform, reducing local stress concentration and reducing the risk of rupture.

[0029] Example 2

[0030] As shown in Figure 2, the flexible elastomer plastic high-pressure cleaner water pipe disclosed in this embodiment has a structure that is basically the same as that in embodiment 1. The only difference is that there are multiple shafts 4, and the multiple shafts 4 are evenly distributed on the outside of the inner tube 3, and the multiple shafts 4 do not intersect each other.

[0031] Example 3

[0032] The flexible elastomer plastic high-pressure washer hose disclosed in this embodiment has a structure that is basically the same as that in embodiment 1. The only difference is that the axis 4 is set between the braided layer 2 and the inner tube 3, and the axis 4 is closely attached to the outer wall surface of the inner tube 3. The axis 4 is also connected to the braided layer and the inner tube 3 through the adhesive layer, so that the hose structure is not layered, thereby ensuring the integrity of the hose.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
