Description

TECHNICAL FIELD

[0001] The utility model belongs to heating article technical field, especially a novel heating cloth. BACKGROUND

[0002] The applicant has previously declared a utility model patent with application number 202323369321.2, which discloses a heating cloth, comprising graphene wires for heating, metal wire for power supply, and yarn for fixing. The graphene wires are arranged in the transverse direction, there are multiple graphene wires arranged in the longitudinal direction, the metal wire is connected with the graphene wires by the method of twisting, and the yarn is connected with the graphene wires and the metal wire.

[0003] The above-mentioned heating cloth has the advantages of being able to be bent at will, being able to be washed directly, and being able to automatically cut off power at high temperature. However, although the method of twisting the metal wire and the graphene wire can increase the stability of the connection between the metal wire and the graphene wire to a certain extent, after long-term use, the connection of the heating cloth will become loose after multiple pressing, bending, and shaking actions, affecting the stability of the connection between the metal wire, the graphene wire, and the yarn.

[0004] Therefore, how to provide a heating cloth with more stable connection has become a technical problem to be solved. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a novel heating cloth with more stable connection and longer service life.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A novel heating cloth, comprising graphene wires for heating, metal wire for power supply, and yarn for fixing. The graphene wires are arranged in the transverse direction, there are multiple graphene wires arranged in the longitudinal direction, the metal wire is connected with the graphene wires by the method of twisting, and the yarn is connected with the graphene wires and the metal wire. The metal wire is formed by twisting a metal wire and a hot melt wire.

[0008] The novel heating cloth sets a hot melt wire in the metal wire. After the novel heating cloth is woven and formed, it is placed in a hot forming device for heating to melt the hot melt wire, thereby bonding the metal wire, the graphene wire, and the yarn into a whole. During long-term use, the connection between the metal wire, the graphene wire, and the yarn remains firm and stable after multiple pressing, bending, and shaking actions, greatly increasing the service life of the novel heating cloth. Meanwhile, the melted hot melt wire can improve the toughness of the metal wire, and the novel heating cloth has better tensile and bending resistance than the traditional metal wire twisted by a metal wire alone.

[0009] Due to the characteristics of graphene itself, the resistance of the graphene wire will increase with the increase of temperature, and when the temperature of the graphene wire reaches a certain value, the resistance will rise exponentially, causing the circuit to be disconnected, thereby ending the heating action, and the melting temperature of the above thermal fuse is greater than the temperature of the heating cloth of the present application when the heating action ends.

[0010] The heating cloth of the present application uses graphene wire to generate heat, and uses the physical properties of the graphene wire itself to achieve circuit breaking, which is safer. The toughness of the graphene wire, metal wire and yarn is good, and they can be bent at will and quickly restored, are not easy to break, can be folded for storage, and can be placed with heavy objects on the heating cloth of the present application during use. The heating cloth of the present application is formed by plain weaving and / or twisting of the graphene wire, metal wire and yarn, and has a very thin thickness, good air and water permeability, can be washed directly, and can be used continuously after drying, and is easy to clean. The thin thickness makes the heating cloth of the present application have better heat dissipation performance, can quickly transfer and dissipate the generated heat, and has the advantage of fast heating speed.

[0011] In the above-mentioned novel heating cloth, the metal wire is formed by twisting two or more metal wires and at least one thermal fuse.

Preferably, the number of the metal wires is 3-5, and the number of the thermal fuses is 2-3. At least two thermal fuses can ensure that the connection between the metal wire and the graphene wire or the yarn is relatively stable after the thermal fuse melts.

[0015] In the above-mentioned novel heating cloth, the graphene wire is wrapped with at least one thermal fuse on the outside.

[0016] The above design can further enhance the stability of the connection between the metal wire, the graphene wire and the yarn.

The polarities of the power sources connected between adjacent two groups of power transmission lines are opposite, which can form a potential difference between the two ends of the small section of graphene wire between the adjacent two groups of power transmission lines, so that each section of graphene wire between the adjacent two groups of power transmission lines can independently heat up. Even if a small section of graphene wire is broken due to external force, it will not affect the normal heating of other small sections on the graphene wire, the heating is more stable, and the overall service life of the new heating cloth is longer.

[0051] The following is the specific embodiment of the utility model and is combined with the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0052] The novel heating cloth includes graphene line 1 for heating, metal wire 21 for power supply and yarn for fixing, graphene line 1 is arranged along the transverse direction, graphene line 1 has multiple and is arranged along the longitudinal direction interval, metal wire 21 is connected with graphene line 1 by the way of twisting, yarn is connected with graphene line 1 and metal wire 21, and metal wire 21 is formed by mutual winding of metal wire 101 and hot melt wire 100.The novel heating cloth is heated by setting hot melt wire 100 in metal wire 21 after novel heating cloth is woven into shape, and then is placed into hot forming equipment, so that hot melt wire 100 is melted, metal wire 21 and the connected graphene line 1 and yarn are bonded into a whole, so that the connection between metal wire 21 and graphene line 1 and yarn is still firm and stable after the novel heating cloth is used for a long time, through multiple pressing, bending, shaking and other actions, which greatly increases the service life of the novel heating cloth;Meanwhile, the toughness of metal wire 21 can be improved after hot melt wire 100 is melted, and the novel heating cloth has more excellent tensile and bending resistance than traditional metal wire 21 twisted by metal wire 101.

[0053] The resistance of the graphene wire 1 increases with the temperature due to the characteristics of the graphene itself, and when the temperature of the graphene wire 1 reaches a certain value, the resistance of the graphene wire 1 increases exponentially, causing the circuit to be disconnected, thereby ending the heating action. The melting temperature of the thermal fuse 100 is greater than the temperature at which the heating cloth of the present application ends the heating action.

[0054] The graphene wire 1 is used to generate heat in the heating cloth of the present application, and the physical characteristics of the graphene wire 1 itself are used to achieve disconnection, which is safer. The toughness of the graphene wire 1, the metal wire 21 and the yarn is good, and they can be bent at will and quickly restored, and are not easy to break. They can be folded and stored, and heavy objects can be placed on the heating cloth of the present application during use. The heating cloth of the present application is formed by plain weaving and / or twisting of the graphene wire 1, the metal wire 21 and the yarn, and has a very thin thickness, good air and water permeability, and can be washed directly. It can be used continuously after drying, and is easy to clean. The thin thickness makes the heating cloth of the present application have better heat dissipation performance, and the generated heat can be quickly transferred and dissipated, which has the advantage of fast heating speed.

[0055] The metal wire 21 in the heating cloth of the present application is a copper wire or a stainless steel wire that can conduct electricity. The voltage range of the power supply adapted to the heating cloth of the present application is 12V-36V.

[0056] As shown in Figures 1-3 The metal wire 21 is formed by twisting two or more metal wires 101 and at least one thermal fuse 100. The plurality of metal wires 101 and the thermal fuse 100 form the metal wire 21 by twisting, which not only increases the firmness and stability of the connection between the metal wire 21 and the graphene wire 1 and the yarn after the thermal fuse 100 melts, but also makes the connection between the plurality of metal wires 21 in the metal wire 21 more firm and stable after the thermal fuse 100 melts, which is beneficial to increasing the structural strength of the metal wire 21. Preferably, the number of the metal wires 101 is 3-5, and the number of the thermal fuses 100 is 2-3. At least two thermal fuses 100 can ensure that the connection between the metal wire 21 and the graphene wire 1 or the yarn is relatively stable after the thermal fuse 100 melts. Figures 1-3 Only several twisting structures of the metal wires 101 and the thermal fuses 100 are shown, which cannot limit the protection scope of the present application. As long as the metal wire 21 is provided with the thermal fuse 100, and the thermal fuse 100 can enhance the structural strength of the metal wire 21 itself and the connection strength between the metal wire 21 and the graphene wire 1 and the yarn after the thermal fuse 100 melts, it should be considered to fall within the protection scope of the present application.

[0057] As shown in Figures 4-6As shown, the yarn is formed by twisting a plurality of fiber filaments 102 and hot melt filaments 100. The addition of hot melt filaments 100 in traditional yarns can make the connection between yarns, yarns and metal wire 21, and yarns and graphene wire 1 more firm and stable, which is conducive to further improving the service life of the new heating cloth. Figures 4-6 Only a few twisted structures of fiber filaments 102 and hot melt filaments 100 are shown, which cannot limit the protection scope of the present application. As long as the yarn is provided with hot melt filaments 100, and the hot melt filaments 100 can enhance the structural strength of the yarn itself and the connection strength of the yarn and the graphene wire 1 and the metal wire 21 after melting, it should be considered to fall within the protection scope of the present application.

[0058] In the new heating cloth, at least one hot melt filament 100 is wound outside the graphene wire 1. The above design can further enhance the stability of the connection of the metal wire 21, the graphene wire 1 and the yarn.

[0059] In the new heating cloth, a plurality of metal wires 21 form a group of power transmission row wires 2, and the polarities of the power sources connected between adjacent two groups of power transmission row wires 2 are opposite. The plurality of metal wires 21 form power transmission row wires 2, which are equivalent to a plurality of parallel electric wires, which can increase the current transmission and facilitate the power transmission row wires 2 to supply power to a plurality of graphene wires 1 at the same time. Further, even if a metal wire 21 is broken due to external force, it will not affect the normal power supply of the graphene wire 1 by the whole power transmission row wire 2. The polarities of the power sources connected between adjacent two groups of power transmission row wires 2 are opposite, which can form a potential difference between the two ends of the graphene wire 1 between the adjacent two groups of power transmission row wires 2, so that each graphene wire 1 between the adjacent two groups of power transmission row wires 2 can independently heat. Even if a small section of the graphene wire 1 is broken due to external force, it will not affect the normal heating of other small sections on the graphene wire 1, the heating is more stable, and the overall service life of the new heating cloth is longer.

[0072] If the metal wire 21 and all the weft yarns 3 are connected by the way of heddle, it may cause the metal wire 21 to be too tight and have no space for elastic movement, forming concave-convex parts on the formed heating cloth, affecting the appearance and being easy to break when pulling the cloth; the weft yarns 3 close to the graphene wire 1 and the metal wire 21 are connected by the way of heddle, and the weft yarns 3 far from the graphene wire 1 and the metal wire 21 are connected by the way of plain weave, which not only ensures the firmness of the connection between the weft yarns 3 around the graphene wire 1 and the metal wire 21, improves the stability of the connection between the metal wire 21 and the graphene wire 1, ensures smooth power supply, but also makes the formed heating cloth more flat and the metal wire 21 not easy to break.

The upper power supply wires and the lower power supply wires are provided with a hot melt wire 100, which can further improve the connection between the upper power supply wires, the lower power supply wires, the metal wires 21, and the yarns 4 after the heating cloth is formed, greatly increasing the service life of the heating cloth. At the same time, the hot melt wire 100 can improve the toughness of the upper power supply wires and the lower power supply wires after melting, and the upper power supply wires and the lower power supply wires have better tensile and bending resistance than traditional upper power supply wires and lower power supply wires twisted by metal wires 101.

It can avoid the reconnection of the broken metal wires 21 after the heating cloth is bent, and can also fix the edge of the circuit breaking hole 7 to ensure the stability of the overall structure of the heating cloth.

[0075] The present application relates to a heating cloth Figures 8-11The connection structure of the crossing and the plain weaving between the wires cannot limit the protection scope of the application; when the metal wire 21, the graphene wire 1 and the weft yarn 3 are connected through the crossing mode, the metal wire 21 and the graphene wire 1 are close to each other, and the metal wire 21 and the weft yarn 3 are close to each other, the gap of the connection is much smaller than that in the drawing, and the gap in the drawing is larger so as to more clearly show the connection structure of the crossing or the plain weaving between the wires.
