Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a water hose and a conveying system. Background Art

[0002] Water hose is a common conveying tool, which is widely used in the fields of agricultural irrigation, fire fighting, cleaning, construction, etc. In some special occasions or special fields, the water hose is not only required to have a conveying function, but also to have a function of indicating direction or facilitating mutual distinction. The prior art discloses some luminous water hoses, for example, a fire hose disclosed in Chinese patent CN217502891 U, a luminous fire hose disclosed in Chinese patent CN218076119 U, and a fire hose disclosed in Chinese patent CN218076120U, etc. These water hoses are equipped with luminous guide lines, which have both a conveying function and can use the luminous guide lines to indicate direction or facilitate mutual distinction. These luminous water hoses can be applied to the field of fire fighting, because in the field of fire fighting, the fire scene is usually harsh and complex, and firefighters and escapees are easy to lose their way. It is necessary to provide route guidance for on-site personnel so that personnel can quickly leave in the direction of the route guidance, which is conducive to improving the transfer efficiency of personnel; if the above-mentioned luminous water hose is used, firefighters can simultaneously complete the construction of route guidance by laying pipelines on site, which is very fast and efficient. Of course, these luminous water hoses can also be widely used in agricultural irrigation, construction and other fields.

[0003] In the existing luminous water hose, the luminous guide line usually adopts a traditional LED light strip, which usually includes a flexible circuit board and LED lamp beads integrated on the flexible circuit board, such as Figure 1As shown, the thickness of the flexible circuit board is relatively thin, but the width is relatively large, so that the flexible circuit board is in the shape of a long strip; although the flexible circuit board is flexible, the flexible circuit board can hardly be stretched, which not only makes the flexible circuit board unable to bend arbitrarily and is not convenient to be flexibly arranged on the water belt, but also in actual use, the water belt will produce a certain amount of expansion and contraction under the action of the internal water pressure, and the flexible circuit board in the LED light belt will be pulled very tight by the water belt, and it is easy to be brittle and broken, affecting normal use. In order to solve this technical problem, a new type of luminous water belt has been developed, in which the luminous guide line is configured to include two wires arranged side by side, and the first lamp bead is connected in parallel to the two wires. When in use, one end of the luminous guide line is connected to the power supply, so that the two wires can be used to replace the flexible circuit board in the existing LED light belt, which can not only play the effect of route guidance, but also make the luminous guide line have good ductility and elasticity, which is convenient for flexible arrangement and can effectively prevent the luminous guide line from breaking. In addition, the volume of the luminous guide line can be greatly reduced, so that the two layers adjacent to the luminous guide line in the water belt still have good adhesion. However, in actual applications, it was found that in the luminous water hose with this structure, the first lamp bead close to the power supply is brighter, and the first lamp bead far away from the power supply is darker, resulting in uneven brightness of the luminous guide line along the length of the water hose, affecting the indication effect, which needs to be solved urgently. Summary of the invention

[0004] The first aspect of the utility model is to solve the above technical problems and provide a water hose with uniform brightness along the length direction, which is conducive to uniform light emission along the length direction of the water hose and achieves better light emission effect. The main concept is:

[0005] A water hose, comprising a water hose body and an electroluminescent wire arranged on the water hose body, wherein the water hose body comprises a lining and a braided layer arranged outside the lining, wherein the lining encloses an internal flow channel, and the two ends of the water hose body are a head end and a tail end respectively;

[0006] The electroluminescent wire comprises a first conductive wire, a second conductive wire, a first return wire and at least two first lamp beads, the first conductive wire and the second conductive wire are arranged in parallel, and a plurality of first lamp beads are connected in parallel between the first conductive wire and the second conductive wire.

[0007] One end of the second conductive wire and the first return wire respectively extends to the head end of the hose body, and is used to connect to the power supply, and the other end of the second conductive wire and the first return wire respectively extends to the tail end of the hose body.

[0008] One end of the first conductive wire extends to the head end of the hose body, and the other end extends to the tail end of the hose body and is connected to the first return wire. The existing conductive wire has a certain elasticity along its length direction, and the existing conductive wire is a linear structure with good flexibility, which can be bent and deformed in any direction. Therefore, in this solution, two parallel arranged first conductive wires and second conductive wires are used to replace the flexible circuit board in the existing luminous water hose, which can not only play the function of route guidance on site, but also make the electroluminescent wire have good ductility and elasticity, which is convenient for flexible arrangement and can effectively prevent the electroluminescent wire from breaking. In addition, the volume of the electroluminescent wire can be greatly reduced, so that the two layers adjacent to the electroluminescent wire in the water hose still have good adhesion, thereby ensuring the service life and reliability of the luminous water hose. By configuring the first return wire and electrically connecting the first conductive wire with the first return wire, the first return wire becomes a partial power supply circuit of each first lamp bead, so that the line length between each first lamp bead and the power supply can be basically equal, and the equivalent resistance can also be basically the same, so that the brightness of each first lamp bead can be basically the same, so that the electroluminescent wire can emit light evenly along the length direction of the water hose body, which can have a more eye-catching route guidance effect.

[0009] To improve reliability, further, one end of the first conductive wire located at the head end of the hose body is configured as insulation; and one end of the second conductive wire located at the tail end of the hose body is configured as insulation. By configuring the idle ends as insulation, interference from external factors can be effectively prevented, making the electroluminescent wire more stable and reliable.

[0010] In order to simplify the manufacturing process of the luminous water hose, further, the first conductive wire and the first return wire are two conductive wires. In the production process, the first conductive wire and the first return wire are not related to each other, so that it is more convenient to continuously produce and manufacture the luminous water hose and improve efficiency; during assembly, it is only necessary to directly connect the first conductive wire and the first return wire at the tail end of the water hose body or connect them through a connecting wire, which is very convenient.

[0011] Preferably, the first return wire is arranged in parallel with the first conductive wire or the second conductive wire, which is beneficial to simplify the structure and process and facilitate on-site wiring operations.

[0012] Preferably, the electroluminescent wires are arranged along the length direction of the hose body.

[0013] In some preferred solutions, the first conductive wire and the second conductive wire are respectively insulated wires. This solution uses insulated wires to replace the existing flexible circuit board, so that the entire luminous water hose has better elasticity and good adhesion, which can ensure the strength and service life of the water hose, and improve the performance of the luminous water hose in terms of service life, stability, and reliability. In addition, it also makes the arrangement position and arrangement method of the electroluminescent wire in the water hose body more flexible and convenient, which is conducive to obtaining a variety of luminous water hose products.

[0014] Preferably, the electroluminescent wire is arranged between the braided layer and the lining or between the braided layers.

[0015] The second aspect of the utility model aims to solve the problem of improving the utilization rate of the wire while preventing the electroluminescent wire from being blocked and affecting the indication effect. Furthermore, the electroluminescent wire also includes a second return wire, and the first return wire and the second return wire are arranged in parallel.

[0016] One end of the second return wire extends to the head end of the hose body, and the other end extends to the tail end of the hose body and is connected to the second conductive wire.

[0017] A number of second lamp beads are connected in parallel between the first return wire and the second return wire. In this solution, by configuring the second return wire and arranging the first return wire and the second return wire in parallel, a number of second lamp beads are connected in parallel between the first return wire and the second return wire, so as to make full use of the first return wire and improve the utilization rate of the line; by connecting the second return wire with the second conductive wire, the first return wire can become part of the power supply circuit of the first lamp bead, and at the same time, the second conductive wire can become part of the power supply circuit of the second lamp bead, so that another group of light-emitting light sources can be formed on the hose body, which can not only ensure that the brightness of each first lamp bead is basically the same, but also To ensure that the brightness of each second lamp bead is basically the same, to achieve the purpose of uniform light emission, and when the power is on, the first lamp bead and the second lamp bead can be lit at the same time, which is conducive to the luminous water hose to be brighter and more eye-catching, and to achieve a better line guidance effect; in addition, the positions of the first lamp bead and the second lamp bead can be set at different positions of the water hose body as needed, so that the electroluminescent line can emit light from multiple directions, which not only makes the electroluminescent line not easily blocked, but also makes the luminous water hose more eye-catching, ensuring that personnel can see the luminous water hose in different directions, avoiding the different laying directions of the water hose affecting the indication effect.

[0018] To improve reliability, further, one end of the first conductive wire located at the head end of the hose body is configured as insulation; one end of the second return wire located at the head end of the hose body is configured as insulation. By configuring the idle end as insulation, interference from external factors can be effectively prevented, making the electroluminescent wire more stable and reliable.

[0019] In order to solve the problem of preventing the electroluminescent line from being blocked and affecting the visual effect, further, the first conductive line, the second conductive line and the first lamp bead in the electroluminescent line form a first luminescent group, the first return wire, the second return wire and the second lamp bead in the electroluminescent line form a second luminescent group, and the first luminescent group and the second luminescent group are arranged relatively along the circumferential direction of the hose body. Since the first luminescent group and the second luminescent group are arranged relatively, after the hose is laid on the ground, there is always a luminescent group located above the hose, so that a more eye-catching luminescent effect can be achieved, and the problem of the electroluminescent line being blocked by the ground and affecting the indication effect can be effectively avoided.

[0020] Preferably, in the first light-emitting group, the light-emitting color of the first lamp bead is green or yellow; in the second light-emitting group, the light-emitting color of the second lamp bead is yellow or green. Green and yellow light have stronger penetration in the white and black smoke at the fire scene, and are easier to be found, so they are more conducive to guiding the direction at the scene.

[0021] Furthermore, along the length direction of the hose body, the first lamp beads in the first light-emitting group are arranged at equal intervals, and the second lamp beads in the second light-emitting group are arranged at equal intervals, which is conducive to achieving a more uniform light-emitting effect along the length direction of the hose body.

[0022] In order to simplify the manufacturing process of the luminous water hose, preferably, the first conductive wire and the first return wire are two conductive wires; the second conductive wire and the second return wire are two conductive wires. In the production process, the first conductive wire and the first return wire are not related to each other, and the second conductive wire and the second return wire are not related to each other, so that it is more convenient to continuously produce and manufacture the luminous water hose and improve efficiency; during assembly, it is only necessary to connect the first conductive wire and the first return wire at the tail end of the water hose body, and connect the second conductive wire and the second return wire at the tail end of the water hose body, which is very convenient.

[0023] A conveying system comprises a conveying power, a water hose joint and the water hose.

[0024] Compared with the prior art, the water hose and conveying system provided by the utility model can not only overcome the problems existing in the traditional luminous water hose and ensure the service life and reliability of the luminous water hose, but also the brightness of each lamp bead is basically the same, so that the electroluminescent line can emit light evenly along the length direction of the water hose body, which can have a more eye-catching route guidance effect.

DETAILED DESCRIPTION

[0036] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the utility model.

[0037] Example 1

[0038] The present embodiment provides a hose, including a hose body 1 and an electroluminescent wire 2 arranged on the hose body 1, wherein the hose body 1 adopts a commonly used conveying hose in the prior art, for example, the hose body 1 can be a fire hose, a polymer flat hose, a rubber hose, a plastic hose, a metal hose, an alloy hose, etc. As an example, the hose body 1 at least includes a lining 11 arranged on the inside and a braided layer 12 arranged on the outside of the lining 11, such as Figure 4 or Figure 5 As shown, the lining 11 is mainly used to enclose an internal flow channel 13 for conveying operations to prevent leakage. The internal flow channel 13 runs through both ends of the hose body 1 so that the internal flow channel 13 can be used to transport liquids (such as water, oil), foam, slurry, gas, solid particles and solid powder, etc. Especially in the field of fire protection, the internal flow channel 13 is mainly used to transport flame-retardant liquids such as high-pressure water or foam to extinguish fires. The braided layer 12 is sleeved on the outside of the lining 11, and can include one braided layer 12, two braided layers 12, three braided layers 12, etc. The braided layer 12 is mainly set to improve the wear resistance and bearing capacity of the hose body 1, and protect the internal lining 11 to make the hose more durable. In implementation, the braided layer 12 usually includes warps and wefts woven together. The material of the lining 11, the material of the warps and the wefts can be realized by existing technology, so that the entire hose body 1 can be bent and curled for laying and storage during subsequent use. It can be understood that in this embodiment, the portion between the braided layer 12 and the internal flow channel 13 is collectively referred to as the lining 11, and the lining 11 can be a single-layer structure, a double-layer structure, or even a multi-layer structure.

[0039] In actual use, the hose body 1 is usually divided into fixed lengths, such as 10m, 20m, 30m, etc. At this time, the hose body 1 has two ends. For ease of description, in this embodiment, the two ends of the hose body 1 can be respectively referred to as the head end 14 and the tail end 15. Figure 3 shown.

[0040] In this embodiment, the electroluminescent wire 2 includes a first conductive wire 21 for conducting electricity, a second conductive wire 22 for conducting electricity, a first return wire 24 for conducting electricity, and at least two first lamp beads 23. Figure 1-Figure 4 As shown, the first conductive wire 21 and the second conductive wire 22 can be arranged in parallel, and a plurality of first lamp beads 23 are connected in parallel between the first conductive wire 21 and the second conductive wire 22. Figure 1-Figure 4 As shown, during implementation, all the first lamp beads 23 can be connected in parallel to the first conductive line 21 and the second conductive line 22, or some of the first lamp beads 23 can be connected in parallel to the first conductive line 21 and the second conductive line 22, and the remaining first lamp beads 23 can be connected in series to the first conductive line 21 or the second conductive line 22.

[0041] In this embodiment, the electroluminescent wire 2 is arranged along the length direction of the hose body 1, so that the first conductive wire 21 and the second conductive wire 22 are also arranged along the length direction of the hose body 1, such as Figure 3 As shown, so as to emit light along the length of the hose body 1, achieving a better route guidance effect. It can be understood that the arrangement along the length direction of the hose body 1 means that the electroluminescent wire 2 as a whole extends along the length direction of the hose body 1, including all technical solutions in which the electroluminescent wire 2 extends from one end of the hose body 1 to the other end. For example, the electroluminescent wire 2 is arranged in a straight line or in a spiral along the length direction of the hose body 1. All arrangements can be understood as the electroluminescent wire 2 being arranged along the length direction of the hose body 1, which will not be repeated in the following text.

[0042] In this embodiment, one end of the second conductive wire 22 and the first return wire 24 extend to the head end 14 of the hose body 1, respectively. Figure 3 As shown, the ends of the second conductive wire 22 and the first return wire 24 are respectively used to connect to the power supply; at the same time, the other ends of the second conductive wire 22 and the first return wire 24 are respectively extended to the tail end 15 of the hose body 1. At this time, the end of the second conductive wire 22 is an idle end. In a more preferred embodiment, one end of the second conductive wire 22 located at the tail end 15 of the hose body 1 can be configured as an insulator 27, such as Figure 3 As shown, by configuring the idle end as insulation 27, interference from external factors can be effectively prevented, making the electroluminescent wire 2 more stable and reliable.

[0043] like Figure 3As shown, one end of the first conductive wire 21 extends to the head end 14 of the hose body 1, and the other end extends to the tail end 15 of the hose body 1, and is connected to the first return wire 24, so that the first conductive wire 21 and the first return wire 24 can be electrically connected. At this time, the end of the first conductive wire 21 located at the head end 14 of the hose body 1 is an idle end. Similarly, in a more preferred embodiment, the end of the first conductive wire 21 located at the head end 14 of the hose body 1 can also be configured as an insulation 27, such as Figure 3 As shown, by configuring the idle end as insulation 27, interference from external factors can be effectively prevented, making the electroluminescent wire 2 more stable and reliable.

[0044] In implementation, the first return wire 24 may also be arranged in parallel with the first conductive wire 21 or the second conductive wire 22. Figure 1-Figure 3 As shown, it is helpful to simplify the structure and process, and facilitate on-site wiring operations. Figure 1 and Figure 3 As shown, the first return wire 24, the first conductive wire 21, and the second conductive wire 22 are arranged in parallel, and each first lamp bead 23 is connected in parallel to the first conductive wire 21 and the second conductive wire 22, respectively. Figure 3 As shown;

[0045] During implementation, there are many ways to configure the idle end for insulation. For example, insulating paint can be sprayed on the idle end to achieve the purpose of insulation, or insulating glue can be applied on the idle end to achieve the purpose of insulation by using the insulating glue; or insulating tape can be configured on the idle end to achieve the purpose of insulation by using the insulating tape.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the first conductive wire 21, the second conductive wire 22 and the first return wire 24 can all be made of existing insulating wires, such as Figure 2As shown, the existing insulated wire generally includes a conductive wire core 31 and an insulating layer 32 that wraps the conductive wire core 31. The conductive wire core 31 is used for conducting electricity. The conductive wire core 31 can be made of copper, aluminum, silver-nickel alloy, brass alloy, stainless steel alloy, etc. The insulating layer 32 mainly plays an insulating role and can be made of an existing plastic layer, rubber layer, insulating paint layer, etc. For example, in this embodiment, the first conductive wire 21, the second conductive wire 22, and the first return wire 24 are all enameled wires, such as enameled copper wires or enameled aluminum wires. The existing insulating wire has a certain ductility (elasticity) along its length, and the existing insulating wire is a linear structure with good flexibility, which can be bent and deformed in any direction. Therefore, in this embodiment, two parallel arranged first conductive wires 21 and second conductive wires 22 are used to replace the flexible circuit board in the existing luminous water hose, which can not only play the function of route guidance on site, but also make the electroluminescent wire 2 have good ductility and elasticity, which is convenient for flexible arrangement and can effectively prevent the electroluminescent wire 2 from breaking. In addition, the volume of the electroluminescent wire 2 can be greatly reduced, so that the two layers adjacent to the electroluminescent wire 2 in the water hose still have good adhesion, thereby ensuring the service life and reliability of the luminous water hose. Of course, in implementation, bare wires can also be used instead of insulating wires to achieve the same effect, which will not be repeated here.

[0047] During implementation, the diameter of the insulating wire can be determined according to actual needs. Preferably, the diameter of the insulating wire can be preferably 0.022 mm to 5 mm, which can effectively improve the ductility and adhesion of the fire hose while meeting the needs of fire hoses of different sizes and different occasions. Of course, the diameter of the insulating wire can also be less than 0.022 mm or greater than 5 mm. As an example, during implementation, the diameter of the insulating wire can preferably be 0.3 mm, 0.38 mm, or 0.4 mm.

[0048] Since the outer layers of the first conductive wire 21 and the second conductive wire 22 are both provided with an insulating layer 32, when manufacturing the electroluminescent wire 2, it is necessary to peel off a portion of the insulating layer 32 at a preset position on the first conductive wire 21 and the second conductive wire 22 to expose the inner conductive wire core 31, and then connect and fix the first lamp bead 23 to the conductive wire core 31 by welding or the like. Figure 1 and Figure 2As shown. Finally, after the first lamp bead 23 is installed, a layer of transparent insulating glue can be coated at the location where the first lamp bead 23 is installed, and the insulating glue is used to coat the first lamp bead 23 and the exposed conductive wire core 31, so that the electroluminescent wire 2 can achieve a better insulation effect. At the same time, the arrangement position of the electroluminescent wire 2 in the water body is more flexible. For example, the electroluminescent wire 2 can be arranged in the internal flow channel 13, between the braided layer 12 and the inner lining, in the braided layer 12, or between two layers of braided layers 12. In order to simplify the process and ensure the brightness, during implementation, the electroluminescent wire 2 can be preferentially arranged between the braided layer 12 and the inner lining (such as Figure 4 As shown) or arranged between the braided layer 12 and the braided layer 12, such as Figure 5 shown.

[0049] In implementation, the number of the first lamp beads 23 and the spacing between adjacent first lamp beads 23 may also be determined according to actual needs. In implementation, the spacing between adjacent first lamp beads 23 may preferably be 2 mm to 2000 mm. Figure 3 As shown, it is ensured that the water belt can emit light more evenly and continuously; more preferably, the spacing between adjacent first lamp beads 23 can be 4mm to 500mm. For example, the spacing between adjacent first lamp beads 23 can preferably be 5mm, 10mm, 15mm, 20mm, 30mm, 50mm, 100mm, 150mm, 200mm, etc.

[0050] Since the first conductive wire 21 is electrically connected to the first return wire 24, in implementation, the first conductive wire 21 and the first return wire 24 can be an integral structure, that is, the first conductive wire 21 and the first return wire 24 can be formed by bending a conductive wire. In order to facilitate production and manufacturing and simplify the process, in a more preferred embodiment, the first conductive wire 21 and the first return wire 24 can be two conductive wires arranged side by side. During assembly, the first conductive wire 21 and the first return wire 24 can be directly connected at the tail end 15 of the hose body 1 or connected through an additional conductive wire 28, such as Figure 3 As shown, it is very convenient, and such a structure is conducive to the continuous production and manufacture of luminous water belts.

[0051] It can be understood that in the present embodiment, the extension to the head end 14 of the water hose body 1 includes but is not limited to the situation where the end of the conductive wire (or the first return wire 24) is flush with the end of the head end 14 of the water hose body 1, and also includes the situation where the end of the conductive wire (or the return wire, wherein the conductive wire includes the first conductive wire 21 and the second conductive wire 22, and the return wire includes the first return wire 24 and the second return wire 25 described later, which will not be repeated later) exceeds the end of the head end 14 of the water hose body 1 by a proper distance, and also includes the situation where the end of the conductive wire does not exceed the end of the head end 14 of the water hose body 1 and is at a proper distance (for example, within 500 mm) from the end of the head end 14 of the water hose body 1 (for example, it passes through the water hose body 1 at a proper distance from the end of the head end 14 of the water hose body 1 to form a tap). Similarly, the extension to the tail end 15 of the hose body 1 includes but is not limited to the situation where the end of the conductive wire (or return wire) is flush with the end of the tail end 15 of the hose body 1, and also includes the situation where the end of the conductive wire exceeds the end of the tail end 15 of the hose body 1 by an appropriate distance, and also includes the situation where the end of the conductive wire does not exceed the end of the tail end 15 of the hose body 1 and is at an appropriate distance from the end of the tail end 15 of the hose body 1 (for example, within 500 mm).

[0052] It can be understood that in this embodiment, the parallel arrangement refers to that the two conductive wires are arranged in substantially the same manner and substantially the same direction, including but not limited to parallel arrangement. In implementation, the spacing between the first conductive wire 21 and the second conductive wire 22 is adapted to install the first lamp bead 23. It can be understood that in implementation, the spacing between the first conductive wire 21 and the second conductive wire 22 between two adjacent first lamp beads 23 can be uniform or uneven, and in both cases, the first conductive wire 21 and the second conductive wire 22 can be considered to be arranged in parallel.

[0053] like Figure 1 or Figure 3 As shown, in the water hose provided in this embodiment, since the first return wire 24 is configured in the electroluminescent wire 2, and the first conductive wire 21 is electrically connected to the first return wire 24, the first return wire 24 becomes a partial power supply circuit of each first lamp bead 23, so that the line length between each first lamp bead 23 and the power supply can be basically the same, and the equivalent resistance can also be basically the same, so that the brightness of each first lamp bead 23 can be basically the same, which can effectively solve the problem of consistent brightness.

[0054] Example 2

[0055] In the technical solution provided in Example 1, the first return conductor 24 is only used to form a closed power supply circuit, resulting in low utilization of the conductor and poor economy. At the same time, when only one electroluminescent wire 2 is configured in the water hose, it is easy to block the electroluminescent wire 2 due to improper laying of the water hose. For example, when the side of the water hose where the electroluminescent wire 2 is configured faces the ground, the electroluminescent wire 2 will be blocked by the ground and is not easy to be seen by on-site personnel, making it difficult to play the role of line indication. Therefore, in order to solve the problem of improving the utilization of the wire while preventing the electroluminescent wire 2 from being blocked and affecting the indication effect, the main difference between Example 2 and Example 1 is that in the water hose provided in this embodiment, the electroluminescent wire 2 also includes a second return conductor 25, and the first return conductor 24 is arranged in parallel with the second return conductor 25, such as Figure 6 and Figure 7 As shown, one end of the second return wire 25 extends to the head end 14 of the hose body 1, and the other end of the second return wire 25 extends to the tail end 15 of the hose body 1 and is electrically connected to the second conductive wire 22, as shown in FIG. Figure 6 and Figure 7 As shown, at the same time, a plurality of second lamp beads 26 are connected in parallel between the first return wire 24 and the second return wire 25 . The number of the second lamp beads 26 can be determined according to actual needs, and the second lamp beads 26 can be the same as the first lamp beads 23 .

[0056] like Figure 6 and Figure 7 As shown, in this embodiment, the end of the first conductive wire 21 located at the head end 14 of the hose body 1 is an idle end. During implementation, this end can be preferably configured as an insulator 27. Figure 6 and Figure 7 As shown, one end of the second return conductor 25 located at the head end 14 of the hose body 1 is also an idle end. During implementation, this end can also be preferentially configured as insulation 27, thereby effectively preventing interference from external factors and making the electroluminescent wire 2 more stable and reliable.

[0057] During implementation, the second return wire 25 can be made of the same material as the first return wire 24 . The second return wire 25 can also preferably be an insulated wire, especially an enameled wire.

[0058] In implementation, the first conductive wire 21 and the first return wire 24 may be an integral structure, that is, the first conductive wire 21 and the first return wire 24 may be formed by bending a conductive wire. In a more preferred embodiment, the first conductive wire 21 and the first return wire 24 may be two conductive wires arranged side by side, such as Figure 6 and Figure 7As shown, during assembly, the first conductive wire 21 and the first return wire 24 are directly connected at the tail end 15 of the hose body 1 or connected through an additional conductive wire 28. Similarly, during implementation, the second conductive wire 22 and the second return wire 25 can also be an integrated structure, that is, the second conductive wire 22 and the second return wire 25 can be formed by bending a conductive wire. In a more preferred embodiment, the second conductive wire 22 and the second return wire 25 can also be two conductive wires arranged side by side, such as Figure 6 and Figure 7 As shown, during assembly, the second conductive wire 22 and the second return wire 25 are directly connected at the tail end 15 of the water hose body 1 or connected through an additional conductive wire 28. This is very simple, convenient and efficient. Such a structure is conducive to the continuous production and manufacture of luminous water hoses.

[0059] In this embodiment, the first conductive wire 21, the second conductive wire 22 and the first lamp bead 23 in the electroluminescent wire 2 can form a first light-emitting group 41 along the length direction of the hose body 1, such as Figure 6 and Figure 7 As shown, at the same time, the first return conductor 24, the second return conductor 25 and the second lamp bead 26 in the electroluminescent wire 2 can form a second light-emitting group 42 along the length direction of the local water body. During implementation, the relative position of the first light-emitting group 41 and the second light-emitting group 42 can be determined according to actual needs, with a variety of arrangements. For example, the first light-emitting group 41 and the second light-emitting group 42 can be arranged at angles of 45 degrees, 60 degrees, 90 degrees, or 120 degrees apart along the circumferential direction of the water hose body 1. For example, in the preferred implementation provided in this embodiment, the first light-emitting group 41 and the second light-emitting group 42 can be arranged relatively along the circumferential direction of the water hose body 1, such as Figure 7 and Figure 8 As shown, the first light-emitting group 41 and the second light-emitting group 42 are arranged at 180 degrees along the circumferential direction of the hose body 1, so that after the hose is laid on the ground, there is always a light-emitting group facing the top of the hose body 1, thereby achieving a more eye-catching lighting effect and effectively avoiding the problem of the electroluminescent line 2 being blocked by the ground and affecting the indication effect.

[0060] During implementation, along the length direction of the hose body 1, the first lamp beads 23 in the first light-emitting group 41 are arranged at equal intervals, such as Figure 6 and Figure 7 As shown, at the same time, the second lamp beads 26 in the second light-emitting group 42 can also be arranged at equal intervals, such as Figure 6 and Figure 7As shown. This is conducive to achieving a more uniform lighting effect along the length direction of the hose body 1. In a further embodiment, each second lamp bead 26 can be respectively arranged at a position between two adjacent first lamp beads 23, so that along the length direction of the hose body 1, the first lamp bead 23 and the second lamp bead 26 can be arranged at equal intervals, such as Figure 7 As shown, it is beneficial to achieve a more uniform lighting effect along the length direction of the water hose body 1.

[0061] During implementation, the luminous color of the first lamp bead 23 may be the same as or different from the luminous color of the second lamp bead 26. For example, in a preferred embodiment, the luminous color of the first lamp bead 23 may be green or yellow, and the luminous color of the second lamp bead 26 may be yellow or green. Preliminary experiments have found that green and yellow light have stronger penetration in the white and black smoke at the fire scene, and are easier to be found, which is more conducive to guiding the direction at the scene.

[0062] The water hose provided in this embodiment is provided with a second return wire 25, and the first return wire 24 and the second return wire 25 are arranged in parallel, so that a plurality of second lamp beads 26 can be connected in parallel between the first return wire 24 and the second return wire 25, so as to make full use of the first return wire 24 and improve the utilization rate of the line; by connecting the second return wire 25 with the second conductive wire 22, the first return wire 24 can become a part of the power supply circuit of the first lamp bead 23, and at the same time, the second conductive wire 22 can become a part of the power supply circuit of the second lamp bead 26, so that a second light-emitting group 42 can be formed on the water hose body 1, which can not only ensure that each first lamp bead The brightness of 23 is basically the same, and it can also ensure that the brightness of each second lamp bead 26 is basically the same, so as to achieve the purpose of uniform light emission, and when power is on, the first lamp bead 23 and the second lamp bead 26 can be lit at the same time, which is conducive to the luminous water hose to be brighter and more eye-catching, and achieve a better line guidance effect; in addition, the positions of the first lamp bead 23 and the second lamp bead 26 can be set at different positions of the water hose body 1 as needed, so that the electroluminescent line 2 can emit light from multiple directions, which not only makes the electroluminescent line 2 not easily blocked, but also makes the luminous water hose more eye-catching, ensuring that people can see the luminous water hose in different directions, avoiding the different laying directions of the water hose affecting the indication effect.

[0065] During implementation, the conveying power may be equipment such as a pump, and the conveying power may be connected to a water hose to provide the power required for conveying.

[0066] During implementation, the water hose can form a pipe network through the water hose connector 5. The water hose connector 5 can adopt an existing connector.
