Technical Field
[0001] This invention relates to the field of smart wearable device technology, and more specifically, to a garment with a detachable self-heating system. Background Technology
[0002] With the development of smart wearable technology, functional clothing is gradually evolving from traditional warmth and aesthetics to multifunctional integration. Especially in cold environments, clothing with electric heating functions has gained widespread attention from users in outdoor sports, special operations, and medical rehabilitation fields due to its advantages such as active heating and adjustable temperature. Electric heating clothing already on the market typically integrates heating elements (usually rigid or semi-rigid heating elements) into the lining or interlayer, and uses a built-in battery to power temperature control. This approach has significant drawbacks: the heating elements are prone to breakage and displacement due to wear and movement, leading to uneven heating and garment deformation; the system is not detachable, requiring complete garment replacement in case of damage, resulting in high maintenance costs and resource waste; the modules lack versatility and cannot be flexibly transferred between various garments; and the power supply relies on a dedicated built-in battery, which has limited battery life and is inconvenient to replace.
[0003] While existing technologies, such as CN101785586A, mention detachable electrically heated fabrics, their modules are tightly integrated with the garment structure, limiting their adaptability. Other heating devices, such as those in US8283602B2, are mostly used in medical settings or beds, and are not suitable for the dynamic wearing environment of clothing. Therefore, there is an urgent need for a self-heating clothing system that is simple in structure, quick to assemble and disassemble, highly versatile, and easy to maintain. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a garment with a detachable self-heating system.
[0005] To solve the above problems, the present invention adopts the following technical solution:
[0006] A garment with a detachable self-heating system includes a garment body and a flexible heating component. The flexible heating component is detachably connected to the garment body via a quick-release structure. The flexible heating component is a strip structure and has multiple heating zones inside.
[0007] The flexible heating component includes a flexible substrate, on which multiple conductive heating layers are disposed. Each conductive heating layer is electrically connected to a control module via a flexible circuit. The control module controls the start / stop and heating power of the conductive heating layers. The control module is electrically connected to a power connector for connecting an external mobile power source.
[0008] As a further aspect of the present invention: the garment body includes an outer cover layer and an inner lining layer, and the flexible heating component is detachably installed in the interlayer between the outer cover layer and the inner lining layer by means of a zipper, magnetic closure, buckle or Velcro.
[0009] As a further aspect of the present invention: the flexible heating component is connected to the garment body via a zipper;
[0010] A transverse groove is provided on the inner side of the outer cover layer, half of the zipper is located at the edge of the groove, and the other half of the zipper is located at the edge of the flexible substrate.
[0011] As a further aspect of the present invention: the conductive heating layer is an elastic heating sheet, the conductive heating layer includes an elastic base layer and conductive particles, the conductive particles are distributed on the fibers of the elastic base layer by means of attachment, embedding or coating to form a conductive network structure.
[0012] As a further aspect of the present invention: the conductive particles are one or more of graphite particles, graphene particles, or carbon nanotube particles; to improve durability, the surface of the conductive heating layer is treated with hydrophobic and waterproof coating to form a hydrophobic and waterproof membrane.
[0013] As a further aspect of the present invention: the control module includes a microcontroller, buttons, and LED indicator lights;
[0014] The microcontroller is configured to respond to button operations and output PWM (Pulse Width Modulation) signals to adjust the heating power of the conductive heating layer, thereby achieving multi-level temperature control and controlling LED indicators to indicate the current temperature level or working status through different colors or flashing patterns.
[0015] As a further aspect of the present invention: the power connector is a USB connector or a Type-C connector, and the garment body also has a cable outlet hole, through which the power cord of the flexible heating component can be connected to an external power source.
[0016] Compared with the prior art, the advantages of this invention are:
[0017] First, the flexible heating element is physically separated from the garment body through a quick-release structure (such as a zipper), allowing the garment to be washed independently and safely, and the heating element to be maintained or replaced separately, greatly improving the product's lifespan and ease of use.
[0018] Second, the standardized component design and interface allow the same heating component to be adapted to multiple garments with the same installation structure, realizing "one module for multiple uses", reducing the user's ownership cost and increasing the product's reusability.
[0019] Third, the heating layer, which is made of a composite of elastic base and conductive particles, is soft, flexible, and can perfectly conform to the curves of the human body, without the stiffness and breakage risk of traditional metal heating wires; the hydrophobic treatment on the surface further improves the safety of use in humid environments.
[0020] Fourth, it integrates a microcontroller-based intelligent control system, which uses PWM technology to achieve precise multi-level temperature adjustment to meet personalized needs; LED indicators provide intuitive status feedback, resulting in a superior user experience.
[0021] Fifth, it supports external power banks (such as portable chargers) that are commonly available on the market. Users can flexibly choose the power capacity according to their needs, which solves the pain points of short battery life and difficulty in replacing built-in batteries, making it especially suitable for long-term outdoor activities.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0031] Please see Figure 1-2A garment with a detachable self-heating system includes a garment body 1 and a flexible heating element 2. The garment body 1 consists of an outer cover layer 11 and an inner lining layer 12. A transverse groove 13 is provided on the inner side of the outer cover layer 11, specifically for accommodating the flexible heating element 2. The flexible heating element 2 is detachably installed in the transverse groove 13 of the inner lining layer by means of quick-release structures such as zippers, magnetic fasteners, buckles, or Velcro, facilitating replacement, cleaning, and reuse. As shown in Figure 2, the quick-release structure in this embodiment is a zipper, with one half of the zipper (male or female) located at the edge of the groove 13, and the other half located at the edge of the flexible heating element 2.
[0032] Additionally, as shown in Figure 2, a cable outlet 14 is provided on the right side of the garment body 1 or inside the pocket for leading out the power cord and connecting it to an external power bank or other portable power source to form a complete electric heating closed-loop system.
[0033] As shown in Figures 2 and 3, the flexible heating element 2 has a strip-like structure. The flexible heating element 2 includes a flexible base 21, and the edge of the flexible base 21 is sewn with the other half of a zipper that matches the groove 13. During installation, simply align the two sets of zippers and pull them together to securely install the flexible heating element 2 in the interlayer between the outer cover layer 11 and the inner liner layer 12.
[0034] Multiple conductive heating layers 22 are spaced apart on a flexible substrate 21. Each conductive heating layer 22 is supported by an elastic substrate layer 221 (such as spandex, polyester fiber, or other elastic fibers). Highly conductive particles 222, such as graphene and carbon nanotubes, are attached, embedded, or coated onto the fiber surface through specific processes, forming a continuous and stable three-dimensional conductive network. This network possesses excellent electrical and thermal conductivity and can achieve stable heating even at low voltages. When current flows through it, the network generates heat due to the resistance effect.
[0035] To enhance safety and environmental adaptability, the entire conductive heating layer 22 undergoes a hydrophobic chemical treatment to form a hydrophobic and waterproof membrane, providing excellent waterproof and moisture-proof performance. This meets daily washing requirements, ensures stable operation of the system in humid or rainy / snowy environments, and extends product lifespan.
[0036] As shown in Figures 3 and 4, the conductive heating layer 22 is electrically connected to the control module 23 via a flexible circuit. The control module 23 controls the start / stop and heating power of the conductive heating layer 22. The control module 23 includes a microcontroller 231, a button 232, and an LED indicator 233. The microcontroller 231 is configured to respond to the operation of the button 232 and output a PWM signal to adjust the heating power of the conductive heating layer 22, thereby achieving multi-level temperature control, and to control the LED indicator to indicate the current temperature level or working status through different colors or flashing patterns.
[0037] The control module 23 is electrically connected to a power connector 24, which is used to connect an external power source. The power connector 24 is either a USB connector or a Type-C connector.
[0038] See Figure 5 The circuit system of control module 23 works as follows: An external power supply provides 5V DC voltage through a USB or Type-C power connector 24. This voltage powers the main heating circuit and is converted to a stable 3.3V by a 3.3V low-dropout linear regulator (LDO) to power the core microcontroller 231 (such as STM8, CH573, etc.). The user inputs commands to the microcontroller 231 by pressing the physical button 232. The microcontroller 231 has a pre-set control program that cycles through the working state (such as power off, low, medium, high) based on the number of button presses. Corresponding to different settings, an I / O pin of the microcontroller 231 outputs a PWM signal with a specific duty cycle. This PWM signal controls the on and off of a MOSFET, thereby precisely regulating the average current flowing through the conductive heating layer 22 and achieving precise temperature control. At the same time, the microcontroller 231 drives multiple LED indicators 233 to visually indicate the current working setting by displaying different colors (such as blue, green, and red).
[0039] After use, the user can easily remove the flexible heating element 2 from the garment body 1 by disconnecting the external power supply and unzipping the garment. The garment body 1 can be washed normally, while the flexible heating element 2 can be wiped clean and stored, or installed on another compatible garment for continued use.
[0040] In summary, this clothing system uses a flexible heating element as its core, combined with a standardized structural interface, convenient assembly method, and universal power supply design. The control system is integrated on the flexible heating component 2, supports multiple temperature settings and LED status indicators, and has functions such as rapid heating, constant temperature operation, and over-temperature protection. It achieves the integrated goals of comfortable wear, flexible power supply, convenient disassembly and assembly, and easy maintenance.
[0041] In use, the user attaches the flexible heating component 2 to the back layer of the garment and connects the interface to a portable power bank. Pressing the button on the control module 23 activates the system to the default heating level. Depending on the ambient temperature and individual needs, the heating level (high, medium, low) can be switched by briefly pressing button 232, with corresponding LED colors indicating different temperature states. After use, the power supply can be disconnected and the zipper pulled down for quick removal, allowing for separate washing of the garment and system reuse. The entire system is compatible with various garment structures; modular installation is possible as long as the garment has standardized module mounting slots and a power outlet. This invention is applicable to various outdoor garments such as smart vests, windbreakers, and cotton-padded jackets.
[0042] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
