Description

Technical Field

[0001] This utility model belongs to the field of new materials technology, specifically relating to a hot-pressed heating cloth. Background Technology

[0002] In winter, especially in the north, temperatures drop sharply, making it difficult for outdoor workers (such as gatekeepers and sanitation workers) to withstand the cold and prone to frostbite. People can only rely on adding layers of clothing to resist the cold, but heavy clothing hinders their work and reduces efficiency. In addition, winter sports (such as skiing and speed skating) require athletes to maintain smooth and comfortable movements without wearing heavy cotton clothing, but they still need to keep their body heat up. Therefore, clothing must not only keep them warm but also not hinder their movements. To meet the need for warmth, traditional 220V electric blankets use AC voltage, which poses electrical safety hazards, is susceptible to moisture, and has a wide range of adverse effects on human health due to electromagnetic radiation.

[0003] To improve safety, a type of heating cloth has emerged on the market, made through weaving or printing. Weaving involves cross-weaving warp and weft threads, but due to equipment and weaving processes, the electrodes and heating wires can only be straight lines, limiting the shape of the heating cloth to rectangular; irregular shapes are virtually impossible to achieve. Therefore, when designing products with irregular shapes, woven heating cloth cannot meet design requirements. Printing methods can achieve irregular shapes using rotary screens, silkscreens, and rollers, but given the diversity of product types and sizes, equipping each product with rotary screens, rollers, and other related equipment would be too costly and difficult to control. Therefore, to ensure safety while reducing the production cost of irregularly shaped heating cloth, a hot-pressing heating cloth method is proposed. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, this utility model proposes a hot-pressed heating cloth, which has the advantage of being able to achieve diverse shapes.

[0006] According to an embodiment of the present invention, a heat-pressed heating cloth includes: a first base cloth and a second base cloth sequentially arranged along the thickness direction of the heating cloth; a conductive layer and a heating layer are provided between the first base cloth and the second base cloth, the conductive layer and the heating layer being sequentially arranged along the thickness direction of the heating cloth; the conductive layer is externally connected to a power source, the conductive layer being composed of a positive conductive wire and a negative conductive wire, the positive conductive wire being connected to the positive terminal of the power source, and the negative conductive wire being connected to the negative terminal of the power source, both the positive and negative conductive wires being flexible conductive materials; the heating layer being composed of multiple heating films, one end of each heating film being connected to a positive conductive wire, and the other end of each heating film being connected to a negative conductive wire; a first adhesive layer is provided on the first base cloth, the first adhesive layer being used to bond the first base cloth and the second base cloth together.

[0007] According to one embodiment of the present invention, one end of both the positive and negative conductive wires is formed with a connection end, the connection end is used to connect to a power source, and an insulating layer is provided on the connection end to seal the connection end after connecting to the power source, thereby providing insulation protection.

[0014] According to one embodiment of the present invention, the first adhesive layer is TPU.

This realizes the laying of the conductive layer according to the shape of the first and second base layer fabrics. While completing the heating, it meets the needs of irregularly shaped heating cloths and realizes the diversification of heating cloth shapes.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following describes the hot-pressed heating cloth of the present invention in detail with reference to the accompanying drawings.

[0029] like Figures 1-3 As shown, the heat-pressed heating cloth according to an embodiment of the present invention includes: a first base cloth 1 and a second base cloth 2 arranged sequentially along the thickness direction of the heating cloth; a conductive layer and a heating layer are provided between the first base cloth 1 and the second base cloth 2, the conductive layer and the heating layer being arranged sequentially along the thickness direction of the heating cloth; a power source is connected to the conductive layer, the conductive layer is composed of a positive conductive wire 31 and a negative conductive wire 32, the positive conductive wire 31 is connected to the positive terminal of the power source, the negative conductive wire 32 is connected to the negative terminal of the power source, and both the positive conductive wire 31 and the negative conductive wire 32 are flexible conductive materials; the heating layer is composed of multiple heating films 4, one end of the heating film 4 is connected to the positive conductive wire 31, and the other end of the heating film 4 is connected to the negative conductive wire 32; a first adhesive layer 51 is provided on the first base cloth 1, the first adhesive layer 51 being used to bond the first base cloth 1 and the second base cloth 2.

[0030] In this embodiment, the heating film 4 is conductive and can be a graphene conductive film or a carbon nanotube film. From bottom to top, the second base fabric 2, conductive layer, heating film 4, first adhesive layer 51, and first base fabric 1 are laid out sequentially. Before laying the first adhesive layer 51, the positive conductive wire 31 and negative conductive wire 32 are connected to a power source. After the first base fabric 1 is laid out, it is hot-pressed to form a complete heating fabric. When laying the positive conductive wire 31 and negative conductive wire 32, they are spaced apart. The length and width dimensions of the first base fabric 1, second base fabric 2, and first adhesive layer 51 are the same. By laying the positive conductive wire 31 and negative conductive wire 32 on the second base fabric 2 and using the heating film 4 to connect the positive conductive wire 31 and negative conductive wire 32 to complete the heating, the conductive layer is laid according to the shape of the first base fabric 1 and second base fabric 2, satisfying the shape requirements of the first base fabric 1 and second base fabric 2 while completing the heating.

[0031] Both the positive conductive wire 31 and the negative conductive wire 32 have a connection end at one end, which is used to connect to the power supply. An insulating layer 6 is provided on the connection end, which is used to seal the connection end after connecting to the power supply, and plays an insulating protection role.

[0032] In this embodiment, the insulating layer 6 is an insulating tape. After the power supply is connected to the positive conductive wire 31 and the negative conductive wire 32 using silicone conductive wires, the insulating tape is applied to the connection end to seal the connection between the silicone conductive wire and the connection end, thus providing insulation protection. The edge of the insulating tape is located inside the edge of the second base layer fabric 2. After the first base layer fabric 1 and the second base layer fabric 2 are bonded together, the insulating layer 6 at the connection end is further sealed, increasing the connection strength between the insulating layer 6 and the connection end and improving safety.

[0033] A power interface 72 is connected between the conductive layer and the power source, and a controller 71 is provided between the power interface 72 and the conductive layer.

[0034] In this embodiment, the controller 71 and the power interface 72, as well as the controller 71 and the conductive layer, are all connected using silicone conductive wires. The controller 71 includes a control motherboard and buttons, and its specific functions can be customized according to user needs. The power interface 72 is used to connect to a power source.

[0035] The positive conductive wire 31 and the negative conductive wire 32 are made of flexible conductive materials that can be pre-formed and shaped, such as copper foil, etched copper, or FPC (printed circuit). The use of pre-formed copper foil, etched copper, or FPC (printed circuit) not only achieves conductivity but also facilitates the preparation of materials according to the required shape, thus meeting the needs of irregularly shaped heating fabrics.

[0036] The heating film 4 is a graphene conductive film.

[0037] The heating film 4 is a carbon nanotube film, and a conductive silver paste layer is provided on the positive electrode conductive wire 31 and the negative electrode conductive wire 32. The conductive silver paste layer is located between the heating layer and the conductive layer.

[0038] In this embodiment, the conductive silver paste layer can act as an adhesive during the hot pressing process, making the heating film 4 more firmly connected to the positive conductive wire 31 and the negative conductive wire 32.

[0039] The second base fabric 2 is provided with a second adhesive layer 52, which is located between the first base fabric 1 and the second base fabric 2.

[0040] In this embodiment, adhesive layers are provided on both the first base layer fabric 1 and the second base layer fabric 2 to increase the strength of the connection. This avoids the situation where the connection area between the second base layer fabric 2 and the first base layer fabric 1 is small when the heating film 4 is laid densely, which would cause the second base layer fabric 2 to peel off during subsequent use or washing, thereby improving its service life.

[0041] The first adhesive layer 51 and the second adhesive layer 52 can be made of the same or different materials, and their thicknesses can be adjusted as needed. The first adhesive layer 51 and the second adhesive layer 52 can be TPU (thermoplastic polyurethane elastomer rubber) or other materials that can achieve bonding after hot pressing.

[0042] The heating film 4 emits heat through radiation, which is low-temperature radiation with transmissibility. It emits infrared rays with a wavelength of 8.97 micrometers, which are beneficial to human health. These rays can be quickly absorbed by the human body, causing microvascular dilation, promoting blood circulation and metabolism, and enhancing the body's immunity, which is very beneficial to health.

[0043] The first adhesive layer 51 and the first base fabric 1 can be bonded together before preparation; the second adhesive layer 52 and the second base fabric 2 can also be bonded together before preparation.

[0044] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
