Description

Technical Field

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

[0002] At the fire scene, there is usually a harsh and complex environment, which makes it easy for fire rescue personnel and escapees to get lost; therefore, it is necessary to provide route guidance for on-site personnel so that they can leave quickly in the direction of the route guidance, which can greatly improve the transfer efficiency of personnel and greatly improve the safety of personnel.

[0003] In order to build route guidance at the fire scene, one of the traditional technical solutions is: an additional fire rescue line or lighting line is laid along the fire hose, and the laid fire rescue line or lighting line is used to provide route guidance for personnel; because this method requires not only laying fire hoses, but also laying additional fire rescue lines or lighting lines, either more fire rescue personnel need to be deployed on site, or the additional weight of fire rescue personnel needs to be increased, which is not conducive to rapid fire fighting and rescue. The second traditional technical solution is: a reflective material or a fluorescent material is arranged on the surface of the fire hose, and the reflective material or the luminous characteristics of the fluorescent material are used to play the role of route guidance. For example, a woven reflective hose disclosed in Chinese patent CN 201621165700.7, a reflective fire hose disclosed in Chinese patent CN 201520380345.4, and a self-luminous fire hose disclosed in Chinese patent CN201620580772.1 can all play the role of route guidance at the scene. However, since this type of fire hose needs to be illuminated in advance before use and its brightness is not high, it is difficult to serve as a route guide at an actual fire scene, especially at night, when visibility is low, or when the scene is filled with smoke. The luminous effect of this type of fire hose is very poor or it may not even glow normally.

[0004] In order to solve the technical problems existing in the above-mentioned traditional technical solutions, some new types of fire hoses have been developed and designed, 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 CN218076120 U, etc., are all equipped with electroluminescent wires in the fire hoses, which can emit light when powered on, not only making the fire hose luminous, but also with high brightness. The luminous effect of the electroluminescent wire is not restricted by environmental factors and is very easy to be seen by personnel, thereby providing effective route guidance for personnel on site. In implementation, the electroluminescent wire can adopt LED light strips. Traditional LED light strips usually include flexible circuit boards and LED lamp beads arranged on the flexible circuit boards, such as Figure 1As shown in FIG. 1 , the flexible circuit board usually has a certain thickness and width, and the flexible circuit board is in a long strip shape, so that the entire LED light strip is in a strip shape; although the flexible circuit board configured in the LED light strip is flexible, Figure 2 and Figure 3 As shown in the figure, after actually setting this traditional LED light strip on the fire hose, the following problems were found: First, in actual use, the fire hose will expand and contract to a certain extent under the action of the internal water pressure, but the flexible circuit board configured in the LED light strip can hardly expand and contract, resulting in the flexible circuit board in the LED light strip being pulled very tightly by the fire hose under the action of the internal pressure, and it is easy to break brittlely (i.e., being pulled apart), affecting normal use; Second, the flexible circuit board in the LED light strip is not easy to weave, so that the LED light strip is usually sandwiched between two adjacent layers in the fire hose to achieve the purpose of fixing the LED light strip. On the one hand, due to the large width of the flexible circuit board in the LED light strip, the contact area between the two adjacent layers in the fire hose will be greatly reduced, such as Figure 2 and Figure 3 As shown, the adhesion between the two adjacent layers is greatly reduced, and the two adjacent layers are easily separated from each other, which greatly reduces the strength and service life of the fire hose; on the other hand, in actual use, the fire hose will expand into a cylindrical shape under the action of internal pressure, and the inner surface, outer surface and cross section of the fire hose are all arc-shaped (circular arc shape). Because the flexible circuit board in the LED light strip is wider, the fire hose is deformed under the action of internal pressure and squeezes the flexible circuit board inward, such as Figure 2 and Figure 3 As shown, it is not only easy to cause damage to the flexible circuit board, but also greatly reduce the adhesion between the flexible circuit board and the fire hose, causing the LED light strip to easily loosen and fall off, which needs to be solved urgently. Summary of the invention

[0005] The first aspect of the utility model is to solve the above technical problems and provide a luminous water hose, which can not only solve the problem that the water hose is easily broken when it is stretched, but also effectively ensure the adhesion of the water hose, and improve the strength and service life of the water hose. The main concept is:

[0006] A luminous water hose comprises a water hose body and an electroluminescent wire arranged on the water hose body, wherein the electroluminescent wire comprises a first conductive wire for conducting electricity, a second conductive wire for conducting electricity, and at least two lamp beads, wherein the first conductive wire and the second conductive wire are arranged in parallel, and a plurality of the lamp beads are connected in parallel between the first conductive wire and the second conductive wire. The existing conductive wires have a certain degree of elasticity along their length direction, and the existing conductive wires are linear structures with good flexibility and can be bent and deformed arbitrarily 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 not only enables the water hose to have the function of luminescence and can serve as a route indication on site, but also, on the first hand, enables the entire water hose to have good ductility and elasticity, and is not prone to the situation where the electroluminescent wire breaks, thereby ensuring that the water hose can be used normally; on the second hand, the volume of the electroluminescent wire is greatly reduced, and the area occupied is also greatly reduced, which can ensure that there is still a large contact area and adhesion between the two adjacent layers, effectively preventing the two adjacent layers from separating from each other, and ensuring the strength and service life of the water hose; on the third hand, the electroluminescent wire itself does not have the risk of loosening and falling off, so that the design can significantly improve the performance of the luminous water hose in terms of service life, stability, and reliability, and better meet market demand. In addition, since the electroluminescent wires are more flexible and can be bent and deformed arbitrarily, not only does the process of integrating the electroluminescent wires into the water hose become simpler, but also the arrangement of the electroluminescent wires in the water hose becomes more flexible and convenient, which is conducive to reducing the cost of the luminous water hose, reducing the manufacturing difficulty of the luminous water hose, and enriching the product structure of the luminous water hose.

[0007] Preferably, the first conductor and the second conductor are arranged along the length direction of the hose body, respectively, so as to emit light along the length direction of the hose body, which can provide a better route guidance effect on site.

[0008] In some preferred schemes, the water hose body includes a lining and a braided layer arranged on the outside of the lining, the lining forms a conveying channel, the first conductive wire and the second conductive wire in the electroluminescent wire are respectively bare wires, the electroluminescent wire is embedded in the lining, and the electroluminescent wire is insulated by the lining. This scheme uses bare wires to replace the existing flexible circuit boards, 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, on the one hand, it is more conducive to reducing costs; on the other hand, when processing and manufacturing the electroluminescent wire, the lamp beads can be welded to the first conductive wire and the second conductive wire without stripping the insulating layer, making the processing and manufacturing process of the electroluminescent wire simpler and more efficient.

[0009] Preferably, the first conductive wire is made of copper wire or aluminum wire, and the second conductive wire is made of copper wire or aluminum wire, which can ensure both conductivity and stretchability.

[0010] In some preferred schemes, the first conductive wire is an insulating wire, and the first conductive wire includes a conductive wire core and an insulating layer wrapping the conductive wire core; the second conductive wire is also an insulating wire, and the second conductive wire includes a conductive wire core and an insulating layer wrapping the conductive wire core, and the lamp bead is connected to the conductive wire core. This scheme uses insulating wire 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 layout position and layout 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.

[0011] Preferably, the conductive core is made of copper wire or aluminum wire.

[0012] Preferably, the insulating layer is an insulating paint layer or an insulating plastic layer.

[0013] Preferably, the first conductive wire is an enameled wire; and the second conductive wire is an enameled wire.

[0014] Preferably, the first conductive wire is an enameled copper wire or an enameled aluminum wire; and the second conductive wire is an enameled copper wire or an enameled aluminum wire.

[0015] Preferably, the diameter of the first conductive wire is 0.022mm-5mm; the diameter of the second conductive wire is 0.022mm-5mm. Not only can it meet the needs of fire hoses of different sizes and different occasions, but the conductive wire has better elasticity, smaller volume, and smaller occupied area, so that the electroluminescent wire has both good elasticity and good adhesion.

[0016] Preferably, the diameter of the first conductive wire is 0.2 mm to 2 mm; the diameter of the second conductive wire is 0.2 mm to 2 mm. This can further improve the stability and reliability of the electroluminescent wire while ensuring a compact size.

[0017] Preferably, the electroluminescent wire is arranged between the braided layer and the lining, or arranged in the delivery channel, or arranged in the braided layer, or embedded in the lining.

[0018] Preferably, the lamp beads are LED lamp beads.

[0019] In order to simplify the molding process and reduce the cost, in some solutions, the two ends of the hose body are the head end and the tail end respectively, one end of the first conductive wire and one end of the second conductive wire are respectively extended to the head end of the hose body for connecting the power supply; the other end of the first conductive wire and the other end of the second conductive wire are respectively extended to the tail end of the hose body and are configured to be insulated. The hose of this structure can achieve a good luminous effect, is not only easy to mold and help reduce costs, but also very convenient for on-site wiring.

[0020] The second aspect of the utility model is to solve the problem of uniform light emission of the electroluminescent line along the length direction of the hose body. Further, the two ends of the hose body are respectively the head end and the tail end.

[0021] The electroluminescent wire also includes a return wire, which is arranged along the length direction of the hose body, and one end of the first conductive wire, the second conductive wire and the return wire respectively extends to the head end of the hose body, wherein the end of the second conductive wire and the end of the return wire are respectively used to connect to a power source, and the end of the first conductive wire is configured to be insulated;

[0022] The other end of the second conductive wire extends to the tail end of the hose body and is configured to be insulated;

[0023] The other end of the first conductive wire extends to the tail end of the hose body, and the other end of the return wire extends to the tail end of the hose body. The first conductive wire and the return wire are connected at the tail end of the hose body. With this design, the resistance between each lamp bead and the power supply can be basically the same, so that the brightness of each lamp bead can be basically the same, so that the electroluminescent wire can emit light evenly along the length direction of the hose body, which can play a more eye-catching route guidance effect.

[0024] In order to simplify the molding process of the luminous water hose, further, the first conductive wire and the return wire are two conductive wires. In the production process, the first conductive wire and the return wire are not related to each other, so that it is more convenient to continuously produce and manufacture the luminous water hose; during assembly, it is only necessary to directly connect the first conductive wire and the return wire at the tail end of the water hose body or connect them through a connecting wire, which is very convenient.

[0025] Preferably, the 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.

[0026] The third aspect of the utility model is to solve the problem of the water hose having a better guiding effect. Furthermore, the electroluminescent wire also includes a third conductive wire, which is arranged in parallel with the first conductive wire, and some lamp beads are connected in parallel with the first conductive wire and the second conductive wire, and some lamp beads are connected in parallel with the first conductive wire and the third conductive wire. The lamp beads connected in parallel with the first conductive wire and the second conductive wire have different luminous colors from the lamp beads connected in parallel with the first conductive wire and the third conductive wire. Thus, the water hose equipped with the electroluminescent wire can emit two colors of light to achieve a better guiding effect.

[0027] A firefighting component comprises a water hose joint and the water hose, wherein the water hose joint is provided with a power supply module, the power supply module comprises a rechargeable battery, one end of the water hose is connected to the water hose joint, and the electroluminescent wire in the water hose is connected to the rechargeable battery.

[0028] Compared with the prior art, the luminous water hose and fire-fighting assembly provided by the utility model have excellent ductility and adhesion, which can not only significantly improve the performance of the luminous water hose in terms of service life, stability and reliability, but also help to reduce the manufacturing difficulty of the luminous water hose, enrich the product structure of the luminous water hose, and better meet market demand.

DETAILED DESCRIPTION

[0048] 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.

[0049] Example 1

[0050] This embodiment provides a luminous water hose, including a water hose body 1 and an electroluminescent wire 2 arranged on the water hose body 1, wherein:

[0051] 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, Figure 3 As shown, the hose body 1 at least includes a lining 11 arranged on the inner side and a braided layer 12 arranged on the outer side of the lining 11, wherein:

[0052] like Figure 3 As shown, the lining 11 can enclose a conveying channel 13 for conveying operations. The conveying channel 13 runs through both ends of the hose body 1, so that liquids (such as water, oil), foams, slurries, gases, solid particles and solid powders can be conveyed through the conveying channel 13. Especially in the field of fire fighting, the conveying channel 13 is mainly used to transport flame-retardant liquids such as high-pressure water or foam for fire extinguishing. The material of the lining 11 can be realized by existing technology, and 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 woven layer 12 and the conveying channel 13 is collectively referred to as the lining 11. The lining 11 can be a single-layer structure, or a double-layer or even a multi-layer structure, which will not be repeated below.

[0053] The braided layer 12 is mainly provided to improve the wear resistance and pressure bearing capacity of the hose body 1 and to protect the internal lining 11 so as to make the hose more durable. In implementation, the braided layer 12 may include warps and wefts woven together, and the warps and wefts may be made of existing materials, which will not be described one by one here.

[0054] In this embodiment, the electroluminescent wire 2 includes a first conductive wire 21 for conducting electricity, a second conductive wire 22 for conducting electricity, and at least two lamp beads 24. Figure 4-Figure 7As shown, at least some of the lamp beads 24 are connected in parallel to the first conductive line 21 and the second conductive line 22, and one end of the first conductive line 21 and the second conductive line 22 is respectively used to connect to a power source, so that the power source can be used to power each lamp bead 24, so that the lamp bead 24 emits light. In a preferred embodiment, each lamp bead 24 is connected in parallel to the first conductive line 21 and the second conductive line 22, and in some cases, some of the lamp beads 24 are allowed to be connected in parallel to the first conductive line 21 and the second conductive line 22, and the remaining lamp beads 24 can be connected in series to the first conductive line 21 or the second conductive line 22.

[0055] In implementation, the first conductive line 21 and the second conductive line 22 may be arranged in parallel. Figure 4-Figure 7 As shown, not only the volume of the entire electroluminescent wire 2 is made smaller, but also the lamp bead 24 is more convenient to connect and fix to the first conductive wire 21 and the second conductive wire 22. Figure 5 shown.

[0056] The electroluminescent wire 2 is arranged along the length direction of the hose body 1. In implementation, the first conductive wire 21 and the second conductive wire 22 can be arranged along the length direction of the hose body 1, respectively. Figure 6 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 refers to the arrangement of the electroluminescent wire 2 as a whole 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 arrangement of the electroluminescent wire 2 in a straight line or in a spiral along the length direction of the hose body 1 can be understood as the arrangement of the electroluminescent wire 2 along the length direction of the hose body 1, which will not be repeated in the following text.

[0057] In this embodiment, the first conductive wire 21 and the second conductive wire 22 are mainly used for conducting electricity. Therefore, in implementation, the first conductive wire 21 and the second conductive wire 22 can adopt conductive wires commonly used in the prior art. For example, in one implementation, the first conductive wire 21 and the second conductive wire 22 can adopt existing bare wires 31 (that is, excluding the insulating layer 42). Figure 4-Figure 7As shown, for example, the first conductive wire 21 and the second conductive wire 22 can be made of copper wire, aluminum wire, silver-nickel alloy wire, etc. It can be understood that although the first conductive wire 21 and the second conductive wire 22 can both be made of bare wire 31, in actual use, the problem of conductive wire insulation still needs to be considered. Therefore, when the first conductive wire 21 and the second conductive wire 22 are both made of bare wire 31, the electroluminescent wire 2 can be preferentially embedded in the hose body 1, and the hose body 1 is used to achieve the purpose of insulation. For example, the electroluminescent wire 2 can be embedded in the lining 11 of the hose body 1, so that the first conductive wire 21 and the second conductive wire 22 are both embedded in the lining 11 of the hose body 1. The lining 11 of the hose body 1 is usually made of insulating material and can play an insulating role, so that the electroluminescent wire 2 can be insulated through the lining 11. Such a design, on the one hand, is more conducive to reducing costs. On the other hand, when manufacturing the electroluminescent wire 2 , the lamp bead 24 can be welded to the first conductive wire 21 and the second conductive wire 22 without stripping the insulating layer 42 , making the manufacturing process of the electroluminescent wire 2 simpler and more efficient.

[0058] In practice, the cross-sectional shape of the bare wire 31 is usually circular or elliptical or similar, and the diameter of the bare wire 31 can be determined according to actual needs. Preferably, the diameter of the bare wire 31 can be preferably 0.022 mm to 5 mm. Figure 5 or Figure 7 As shown, it 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 bare wire 31 can also be less than 0.022mm or greater than 5mm, which will not be repeated here. In a preferred embodiment, the diameter of the first conductive wire can be 0.2mm~2mm; similarly, the diameter of the second conductive wire can be 0.2mm~2mm. The stability and reliability of the electroluminescent wire can be further improved while ensuring a compact size. As an example, in this embodiment, the diameter of the bare wire 31 can preferably be 0.35mm or 0.38mm or 0.4mm, etc.

[0059] For example, in another embodiment, the first conductive wire 21 and the second conductive wire 22 can be made of existing insulating wires. In this case, the first conductive wire 21 includes a conductive wire core 41 and an insulating layer 42 wrapping the conductive wire core 41. Figure 8 and Fig. 9As shown, similarly, the second conductive wire 22 includes a conductive wire core 41 and an insulating layer 42 wrapping the conductive wire core 41, wherein the conductive wire core 41 is used for conducting electricity, which is equivalent to the above-mentioned bare wire 31. Therefore, in implementation, the conductive wire core 41 can preferably use copper wire or aluminum wire or silver-nickel alloy wire or brass alloy wire or stainless steel alloy wire, etc., which can be a combination of one strand or multiple strands. The insulating layer 42 mainly plays an insulating role, and can use existing insulating materials. For example, the insulating layer 42 can use an insulating paint layer or an insulating plastic layer or a rubber layer. In implementation, the first conductive wire 21 and the second conductive wire 22 can respectively use copper wire or aluminum wire or silver-nickel alloy wire or brass alloy wire or stainless steel alloy wire (all with insulating layer 42). In the preferred implementation provided in this embodiment, the first conductive wire 21 and the second conductive wire 22 can preferably use enameled wire. As an example, the first conductive wire 21 and the second conductive wire 22 can preferably use enameled copper wire or enameled aluminum wire.

[0060] like Figure 8 and Fig. 9 As shown, the lamp bead 24 is respectively connected to the conductive core 41 of the first conductive wire 21 and the conductive core 41 of the second conductive wire 22 to form a power supply circuit. Since the outer layers of the first conductive wire 21 and the second conductive wire 22 are both provided with an insulating layer 42, when processing and manufacturing the electroluminescent wire 2, it is necessary to peel off part of the insulating layer 42 at the preset positions on the first conductive wire 21 and the second conductive wire 22 to expose the internal conductive core 41, and then connect and fix the lamp bead 24 to the conductive core 41 of the first conductive wire 21 and the conductive core 41 of the second conductive wire 22 by welding or the like. In a more perfect solution, in order to achieve a better insulation effect at the position of the lamp bead 24, after the lamp bead 24 is installed, a layer of transparent insulating glue 5 can be coated at the position where the lamp bead 24 is installed, such as Fig.10 As shown, using the insulating glue 5 to cover the lamp bead 24 and the exposed conductive wire core 41 will not only not affect the brightness of the lamp bead 24, but also achieve better insulation and strengthen the welding point.

[0061] With the electroluminescent wire 2 of this structure, there is no need to consider the insulation problem of the first conductive wire 21 and the second conductive wire 22, so that the electroluminescent wire 2 can be arranged in more ways in the water body. For example, the electroluminescent wire 2 can also be arranged between the braided layer 12 and the lining, such as Figure 7 As shown, it can also be arranged in the conveying channel 13. Of course, it can also be woven into the braided layer 12 as a warp or weft or directly arranged between two adjacent braided layers 12.

[0062] Similarly, during implementation, the cross-sectional shape of the insulating wire is usually circular or elliptical or similar, and the diameter of the insulating wire can be determined according to actual needs. Preferably, the diameter of the insulating wire can be preferably 0.022mm to 5mm, which can effectively improve the ductility and adhesion of the 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 0.022mm or greater than 5mm, which will not be repeated here. More preferably, the diameter of the insulating wire can be 0.2mm to 2mm. As an example, in this embodiment, the diameter of the insulating wire can be preferably 0.35mm or 0.38mm or 0.4mm, etc.

[0063] For ease of description, the two ends of the hose body 1 are respectively a head end 14 and a tail end 15. Figure 6 In implementation, the first conductive line 21 and the second conductive line 22 are arranged in parallel, and one end of the first conductive line 21 and the second conductive line 22 can be respectively extended to the head end 14 of the hose body 1 to connect to the power supply, such as Figure 6 or Figure 8 As shown, the other ends of the first conductive wire 21 and the second conductive wire 22 can extend to the tail end 15 of the hose body 1 respectively, and the ends can be configured as insulation 25. For example, insulating paint can be sprayed on the ends to achieve the purpose of insulation, or insulating glue 5 can be applied on the ends to achieve the purpose of insulation; insulating tape can also be configured on the ends to achieve the purpose of insulation.

[0064] The existing bare wires and insulated wires have a certain degree of ductility (i.e., elasticity) along their length direction, and the existing bare wires and insulated wires are linear structures, not plate-shaped or sheet-shaped structures, and have good flexibility and can be bent and deformed arbitrarily; therefore, the water hose provided in this embodiment directly connects the lamp beads 24 to the conductive wires (including the first conductive wires 21 and the second conductive wires 22) to form an electroluminescent wire 2, replacing the flexible circuit board in the prior art, and the electroluminescent wire 2 is arranged on the water hose body 1, which not only makes the water hose have the function of emitting light, but also can play the role of route indication on site, and more importantly: first, the electroluminescent wire 2 in the water hose can be retracted and extended, In actual use, when the fire hose expands and contracts under the action of internal water pressure, the electroluminescent wire 2 can also expand and contract synchronously, and it is not easy to be broken, ensuring the normal use of the hose; second, the volume of the electroluminescent wire 2 is greatly reduced, especially when the first conductive wire 21 and the second conductive wire 22 are both made of enameled wires of about 0.38mm, the volume of the electroluminescent wire 2 is very small. When the electroluminescent wire 2 is sandwiched between two adjacent layers in the hose, it will not greatly reduce the contact area between the two adjacent layers in the fire hose, ensuring that the two adjacent layers still have a large contact area and adhesion, effectively preventing the two adjacent layers from separating from each other, and ensuring the strength and service life of the hose. Third, because the electroluminescent wire 2 uses a linear conductive wire, in actual use, the deformation of the hose under the action of internal pressure is not easy to damage the conductive wire, nor will it reduce the adhesion between the conductive wire and the hose. The electroluminescent wire 2 does not have the risk of loosening and falling off, thereby significantly improving the performance of the luminous hose in terms of service life, stability, and reliability, and better meeting market demand.

[0065] In addition, since the electroluminescent wire 2 in this embodiment is more flexible and can be bent and deformed arbitrarily, not only the process of integrating the electroluminescent wire 2 in the water hose is simpler, but also the arrangement of the electroluminescent wire 2 in the water hose is more flexible and convenient. For example, the electroluminescent wire 2 can be more conveniently arranged in a spiral manner in the water hose body 1, which is also beneficial to reduce the cost of the luminous water hose, reduce the difficulty of manufacturing the luminous water hose, and enrich the product structure of the luminous water hose.

[0066] In implementation, the number of lamp beads 24 can be determined according to actual needs, and the spacing between adjacent lamp beads 24 can also be determined according to actual needs. In implementation, the spacing between adjacent lamp beads 24 can preferably be 2mm to 2000mm to ensure that the water hose can emit light more evenly and continuously. More preferably, the spacing between adjacent lamp beads 24 can be 4mm to 500mm. For example, the spacing between adjacent lamp beads 24 can preferably be 5mm, 10mm, 15mm, 20mm, 30mm, 50mm, 100mm, 150mm, etc. In implementation, the lamp beads 24 preferably use LED lamp beads 24, which are not only small in size, high in brightness, low in heat generation, low in power consumption, and long in service life, but also not easy to be damaged. They can work normally and stably under violent use, and can significantly improve the reliability and stability of the luminous water hose. Of course, it can be understood that in implementation, the lamp beads 24 can also use other commonly used lamp beads 24 in the prior art, and no examples are given here.

[0067] During implementation, the number of conductive wires configured in the electroluminescent wire 2 can be determined according to actual needs, and the number of conductive wires can be 2, 3, 4, 5, etc. For example, in one embodiment, the electroluminescent wire 2 further includes a third conductive wire 23, and the third conductive wire 23 can also be arranged in parallel with the first conductive wire 21. In this case, the first conductive wire 21 can be used as a common ground wire, and some of the lamp beads 24 are connected in parallel to the first conductive wire 21 and the second conductive wire 22, and some of the lamp beads 24 are connected in parallel to the first conductive wire 21 and the third conductive wire 23. Figure 11-13 As shown, the light emitting colors of the lamp bead 24 connected in parallel to the first conductive wire 21 and the second conductive wire 22 and the lamp bead 24 connected in parallel to the first conductive wire 21 and the third conductive wire 23 can be different, so that the water hose equipped with the electroluminescent wire 2 can emit two colors of light to achieve a better guiding effect. Similarly, in another embodiment, the electroluminescent wire 2 also includes a third conductive wire 23 and a fourth conductive wire, and the third conductive wire 23 and the fourth conductive wire can also be arranged in parallel with the first conductive wire 21. At this time, the first conductive wire 21 can be used as a common grounding wire, and some lamp beads 24 are connected in parallel to the first conductive wire 21 and the second conductive wire 22, some lamp beads 24 are connected in parallel to the first conductive wire 21 and the third conductive wire 23, and some lamp beads 24 are connected in parallel to the first conductive wire 21 and the fourth conductive wire. The luminous colors of the lamp beads 24 connected in parallel to the first conductive wire 21 and the second conductive wire 22 and the lamp beads 24 connected in parallel to the first conductive wire 21 and the third conductive wire 23 and the lamp beads 24 connected in parallel to the first conductive wire 21 and the fourth conductive wire can be different, so that the water hose equipped with the electroluminescent wire 2 can emit three colors of light to achieve a better guiding effect.

[0068] 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 lamp beads 24. It can be understood that in implementation, the spacing between the first conductive wire 21 and the second conductive wire 22 between two adjacent lamp beads 24 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.

[0069] It can be understood that in this embodiment, the diameter refers to the outer diameter.

[0070] Example 2

[0071] Due to the structure of the electroluminescent wire 2 in Example 1, when in use, the resistance between each lamp bead 24 and the power supply is very different, so that along the length direction of the water hose, the lamp bead 24 close to the power supply is brighter, and the lamp bead 24 far away from the power supply is darker, resulting in uneven brightness of the electroluminescent wire 2 along the length direction of the water hose body 1. In order to solve this technical problem, the main difference between this embodiment 2 and the above-mentioned embodiment 1 is that in the water hose provided in this embodiment, the electroluminescent wire 2 also includes a return wire 6, such as Figure 14-15 As shown, the return wire 6 can also be arranged along the length direction of the water hose body 1, and in implementation, the return wire 6 also has a variety of arrangement positions, for example, the return wire 6 can be embedded in the lining of the water hose, or can be arranged between the braided layer 12 and the lining, or can be arranged in the conveying channel 13. Of course, it can also be woven into the braided layer 12 as a warp or weft or directly arranged in the braided layer 12. In implementation, the return wire 6 can be arranged at the same position as the first conductive wire 21 and the second conductive wire 22. For example, the return wire 6 and the first conductive wire 21 and the second conductive wire 22 can all be embedded in the lining at the same time, which is conducive to simplifying the molding process of the luminous water hose. Of course, in implementation, the return wire 6 and the first conductive wire 21 and the second conductive wire 22 can also be arranged at different positions respectively, and examples are not given here one by one.

[0072] The material of the return wire 6 can be the same as that of the first conductive wire 21. For example, the return wire 6 can be the above-mentioned bare wire 31 or an insulated wire, especially an enameled wire. Examples are not given here one by one. In implementation, the return wire 6 can be arranged in parallel with the first conductive wire 21 or the second conductive wire 22. Figure 14-15 As shown, the return wire 6, the first conductive wire 21, and the second conductive wire 22 are arranged in parallel, and each lamp bead 24 is connected in parallel to the first conductive wire 21 and the second conductive wire 22, respectively. Figure 14-15 As shown;

[0073] One end of the first conductive wire 21, the second conductive wire 22 and the return wire 6 can extend to the head end 14 of the hose body 1 respectively. Fig.15 As shown, the end of the second conductive wire 22 and the end of the return wire 6 are respectively used to connect to the power supply, and the end of the first conductive wire 21 is configured as an insulation 25, as shown in FIG. Fig.15 The other end of the second conductive wire 22 extends to the tail end 15 of the hose body 1, and the end is also configured as an insulator 25, as shown Fig.15 As shown; the other end of the first conductive wire 21 can also extend to the tail end 15 of the hose body 1, and the other end of the return wire 6 can also extend to the tail end 15 of the hose body 1. The first conductive wire 21 and the return wire 6 can be connected at the tail end 15 of the hose body 1, as shown Fig.15 As shown; in implementation, the first conductive wire 21 and the return wire 6 can be an integral structure, that is, the first conductive wire 21 and the return wire 6 can be formed by bending a conductive wire. In order to facilitate the production and manufacture of the luminous water hose in this embodiment, in a more preferred embodiment, the first conductive wire 21 and the return wire 6 can be two conductive wires arranged side by side. When assembling, the first conductive wire 21 and the return wire 6 can be directly connected at the tail end 15 of the water hose body 1 or connected through a connecting wire, which is very convenient. Such a structure is conducive to the continuous production and manufacture of the luminous water hose.

[0074] Similarly, during implementation, the number of conductive wires configured in the electroluminescent wire 2 can be determined according to actual needs. For example, in one embodiment, the electroluminescent wire 2 further includes a third conductive wire 23, and the third conductive wire 23 can also be arranged in parallel with the first conductive wire 21, such as Fig.16 As shown, one end of the third conductive line 23 extends to the head end 14 of the hose body 1 for connecting to a power source, and the other end of the third conductive line 23 extends to the tail end 15 of the hose body 1 and is configured as an insulator 25. Fig.16 As shown, the first conductive line 21 can be used as a common line, such as a ground line, some lamp beads 24 are connected in parallel to the first conductive line 21 and the second conductive line 22, and some lamp beads 24 are connected in parallel to the first conductive line 21 and the third conductive line 23, and the light-emitting colors of the lamp beads 24 connected in parallel to the first conductive line 21 and the second conductive line 22 and the lamp beads 24 connected in parallel to the first conductive line 21 and the third conductive line 23 can be different, so that the water hose equipped with the electroluminescent line 2 can emit two colors of light to achieve a better guiding effect. Of course, the electroluminescent line 2 can also be equipped with a fourth conductive line, a fifth conductive line, a sixth conductive line, etc., which will not be illustrated one by one here.

[0075] In the water hose provided in this embodiment, the resistance between each lamp bead 24 and the power supply can be basically the same, so that the brightness of each lamp bead 24 can be basically the same, so that the electroluminescent wire 2 can emit light evenly along the length direction of the water hose body 1, achieving a more eye-catching route guidance effect.

[0076] It can be understood that in this embodiment, the extension to the head end of the water hose body includes but is not limited to the situation where the ends of the conductive wire and the return wire are flush with the end of the head end of the water hose body, and also includes the situation where the ends of the conductive wire and the return wire exceed the end of the head end of the water hose body by a proper distance, and also includes the situation where the ends of the conductive wire and the return wire do not exceed the end of the head end of the water hose body, and are at a proper distance (for example, within 500mm) from the end of the head end of the water hose body (for example, passing 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 of the water hose body includes but is not limited to the situation where the ends of the conductive wire and the return wire are flush with the end of the tail end of the water hose body, and also includes the situation where the ends of the conductive wire and the return wire exceed the end of the tail end of the water hose body by an appropriate distance, and also includes the situation where the ends of the conductive wire and the return wire do not exceed the end of the tail end of the water hose body and are an appropriate distance away from the end of the tail end of the water hose body (for example, within 500mm) (for example, passing through the water hose body 1 at an appropriate distance from the end of the head end 14 of the water hose body 1 to form a tap).

[0077] Example 3

[0078] This embodiment 3 provides a firefighting assembly, including a hose connector 7 and the above-mentioned hose, the hose connector 7 is provided with a power supply module, the power supply module includes a rechargeable battery 71, one end (such as the head end) of the hose is connected to the hose connector 7, and the electroluminescent wire 2 in the hose is connected to the rechargeable battery 71, such as Fig.17 As shown, the power supply module is used to power the electroluminescent wire 2 in the water belt, so that the electroluminescent wire 2 can emit light continuously and stably.

[0079] During implementation, the water hose connector 7 can adopt an existing connector, for example, a male connector or a female connector commonly used in the fire protection field, for example, a KDK65 type card-type fire protection connector, a KD65 type internal buckle connector, etc., which will not be explained one by one here.
