Abstract
Description
Technical Field
[0001] The present application relates to the technical field of heating and warmth preservation applications, and in particular to a cloth that can be heated by a power source. Background Art
[0002] Keeping warm is one of the important indicators of winter clothes. Traditional winter warm clothing is made of cotton, linen, silk, wool, polyester, nylon, nylon and man-made fibers to form warm fabrics, which are then used to prepare warm clothing. However, the warming effect of these traditional warm materials mainly depends on the thickness and density of the formed fabrics. The thicker the thickness, the better the warming effect. Once the thickness becomes thinner, the warming effect will become worse. The warming function of traditional warm materials is limited by conditions, which is not conducive to people's use.
[0003] With the development of social science and technology, people use electric heating wires on fabrics to make clothing play a good role in heating, keeping warm and keeping out the cold. However, the existing electric heating wires have slow heating speed, low heating efficiency and low safety, and need to be improved. Utility Model Content
[0004] In order to solve the problems of slow heating speed, low heating efficiency and low safety of electric heating wires, the present application provides a cloth that can be heated by a power source.
[0005] The present application provides a power-heatable cloth, which adopts the following technical solution:
[0006] A cloth that can be heated by a power supply, comprising a fabric and a heating component sewn and fixed on the surface of the fabric, the heating component comprising a power supply, at least two heating wires and two conductive wires, the heating wires are sewn and fixed on the surface of the fabric, one end of each of the heating wires is commonly connected to one end of one of the conductive wires, and the other end of the conductive wire is connected to the positive electrode of the power supply; the other end of each of the heating wires is commonly connected to one end of another of the conductive wires, and the other end of the conductive wire is connected to the negative electrode of the power supply, thereby forming a parallel circuit;
[0007] The heating wire is a nano-carbon crystal wire;
[0008] The side walls of the nano-carbon crystal wires are wrapped with a protective layer.
[0009] By adopting the above technical solution, the heating and warmth-keeping effect of the fabric is good, the heat conversion rate of the heating wire is high, and the power consumption is low. In this application, the heating wire is arranged and connected to the fabric in parallel, so that the heating wire can be distributed on the fabric to the greatest extent, and the heating process is stable and safe. Nano-carbon crystal wire has high thermal conductivity efficiency, long service life and good softness. It can be used to prepare heating wire to improve the heat conversion efficiency, further improve the warmth-keeping effect of the fabric, and extend the service life of the heating wire. Nano-carbon crystal wire has good toughness and can be folded multiple times without deformation, which will not affect the heating efficiency.
[0010] At the same time, nano-carbon crystal wire is light and soft, and will not feel like a foreign body when used to prepare thermal conductive wires. It can also be used to prepare clothing to improve the comfort of wearing clothing.
[0011] The protective layer protects the nano-carbon crystal wire from being damaged during use. When the cloth that can be heated by a power source is used to make clothing, it will be washed frequently during use. The protective layer wrapped around the outer wall of the nano-carbon crystal wire protects the nano-carbon crystal from being easily damaged by external forces during the washing process. Experiments have shown that the cloth that can be heated by a power source in this application can be machine washed 98 times without being damaged.
[0012] Optionally, a metal connecting block is fixed at the connection between the heating wire and the conductive wire.
[0013] By adopting the above technical solution, the metal connecting block is used to fix the connection between the heating wire and the conductive wire, so that the connection between the two is not easy to loosen. The heating wire and the conductive wire are generally connected together by welding or knotting, but the connection stability of the above two methods is poor and it is easy to fall off during use. In this regard, the present application uses a metal connecting block to tightly clamp the heating wire and the conductive wire together, so that only the connecting block can stably connect the heating wire and the conductive wire together, which can effectively prevent the heating wire and the conductive wire from loosening and separating, and improve heating stability. Preferably, the metal connecting block is a copper connecting block, an iron connecting block or a silver connecting block, and its metal properties can maintain the electrical connection between the heating wire and the conductive wire.
[0014] Preferably, the metal connection block is provided with two adjacent through holes, wherein one of the through holes is for the heating wire to pass through and be fixed, and the other through hole is for the conductive wire to pass through and be fixed.
[0015] By adopting the above technical solution, the heating wire and the conductive wire can be stably connected and are not easy to fall off during daily use and washing. Specifically, the conductive wire is embedded in one of the through holes so that the conductive wire is stably connected to the metal connecting block, and then the heating wire is embedded in another through hole so that the heating wire is connected to the metal connecting block, thereby achieving a stable connection between the conductive wire and the heating wire.
[0016] Preferably, the outer surface of the metal connecting block is sheathed with a soft rubber tube.
[0017] By adopting the above technical solution, the metal connecting block is protected to prevent the metal connecting block from being damaged during use.
[0018] Preferably, the conductive wire is at least one of an aluminum wire, a copper wire and a silver wire.
[0019] The conductive wire has good conductivity and can transmit electrical energy to the heating wire quickly and stably, thereby improving heating efficiency.
[0020] Preferably, the fabric is elastic fabric.
[0021] By adopting the above technical solution, the power-heated fabric has a wider range of applicability, and can be applied to clothing worn by the human body or products such as cushions and mattresses for daily use. The elastic fabric can be stretched and deformed with the range of movement of the human body to improve the comfort of the clothing and products prepared by the application.
[0022] Preferably, the middle section of the heating wire is fixed to the surface of the fabric by means of herringbone stitching or embroidery stitching.
[0023] By adopting the above technical solution, the heating wire can be stably connected to the fabric and will not fall off during use. The herringbone sewing can form a suture similar to a herringbone shape, making the structure of the suture more solid. By staggering and arranging the herringbone-shaped sutures on both sides of the heating wire, the heating wire can be stably fixed to the fabric from both sides, thereby improving the ability of the heating wire to be stably connected to the fabric.
[0024] Preferably, the arrangement shape of the middle section of the heating wire on the fabric is one of wave shape, arc shape, zigzag shape and U shape.
[0025] By adopting the above technical scheme, a wavy, arc-shaped, zigzag or U-shaped heating wire with a longer total length can be set on the surface of the fabric per unit area, thereby increasing the contact area between the heating wire and the fabric, making each area of the fabric heated more evenly and improving the effect of keeping warm.
[0026] On the other hand, when elastic fabrics are used, the wavy, arc-shaped, zigzag-shaped, and U-shaped heating wire arrangements provide a certain stretching buffer space for the heating wires, so that when the fabrics undergo elastic stretching deformation, the heating wires in the above arrangement shapes can also deform in coordination with the stretching deformation of the elastic fabrics, making it difficult for the heating wires to be broken during multiple washings and uses.
[0027] In summary, the present application includes at least one of the following beneficial technical effects:
[0028] The present application uses nano-carbon crystal wire as the heating wire, which can improve the heat conversion rate of the heating wire and reduce energy consumption. At the same time, the present application connects one end of each heating wire to one end of one of the conductive wires, and the other end of the conductive wire is connected to the positive electrode of the power supply; the other end of the heating wire is connected to one end of another conductive wire, and the other end of the conductive wire is connected to the negative electrode of the power supply, and the heating wire is fixed to the fabric, thereby forming a parallel circuit, so that the heating process of the heating wire is stable and safe, and multiple heating wires can be heated at the same time, thereby improving the heating effect of the fabric.
