Description

Technical Field

[0001] This invention relates to the field of negative ion heating structure technology, and in particular to a flexible negative ion heating structure. Background Technology

[0002] With people's increasing demands for a healthy quality of life, flexible physiotherapy products that integrate heating, warmth, and negative ion therapy have attracted widespread market attention. Currently, the technical approaches for related products mainly fall into the following categories, all of which have significant drawbacks: Category 1: Single-function heating products.

[0003] Existing graphene heated mattresses, cushions, and therapeutic mats, such as the graphene intelligent temperature-controlled heated mattress structure disclosed in invention patent CN216059952U, include an antibacterial air fabric layer, 3D breathable mesh fabric on all four sides of the antibacterial air fabric layer, a graphene heating layer on the inner side of the antibacterial air fabric layer, a high-density sponge layer below the graphene heating layer, and a 3D support material layer below the high-density sponge layer. These products only have a heating function and do not have a negative ion release function, making their functions limited.

[0004] Category 2: Products that combine negative ions with heating.

[0005] To achieve the dual effects of heating and negative ions, existing technologies, such as the invention patent disclosed in CN108192327B (which describes a flexible graphene electrothermal composite film and its preparation method), involve mixing and dispersing negative ion powder and graphene electrothermal material in the same flexible resin matrix to form a flexible composite film. While this method of mixing the negative ion functional phase with the heating material in the same film layer is structurally simple, it has drawbacks: the composite film layer itself forms a closed barrier against the outward diffusion of negative ions. The negative ions are trapped inside the film and cannot be effectively released and diffused outward, resulting in a lower negative ion release rate in actual use compared to the theoretical value, significantly reducing the health and therapeutic effects.

[0006] Another product, such as the graphene scarf with a built-in negative ion releasing chip disclosed in the invention patent with publication number CN211884984U, directly attaches the negative ion releasing chip to the surface of the graphene heating plate, and the outer layer of cotton cloth seals and wraps the two together. It also fails to provide an effective channel for the negative ions to diffuse outward, resulting in low negative ion release efficiency.

[0007] Category 3: Layered and composite negative ion functional products.

[0008] Patent CN220686482U discloses a graphene negative ion health board, mainly comprising an outer surface layer, a negative ion releasing layer, a structural support layer, and an air layer. A negative ion releasing layer is disposed between two outer surface layers, at least on one side. One or more structural support layers are included between the two outer surface layers to provide structural strength to the board. An air layer is disposed between the negative ion releasing layer and the structural support layer. Although this design incorporates independent negative ion releasing and support layers, it suffers from the following problems: First, the product lacks any heating function; second, the structural support layer is a rigid material, resulting in a rigid overall structure that cannot conform to the irregular curves of the human body, making it unsuitable for wearable or flexible therapeutic products such as mats, blankets, and protective gear.

[0009] Therefore, how to provide a physiotherapy structure that can simultaneously achieve heating and negative ion release functions in a flexible structure, and has a complete negative ion diffusion path, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0010] To address the aforementioned technical problem of how to provide a therapeutic structure that simultaneously achieves heating and negative ion release functions within a flexible structure, while possessing a complete negative ion outward diffusion path, this invention proposes a negative ion heating flexible structure. The technical solution used is as follows: A flexible structure for negative ion heating includes a flexible heating mesh, a flexible perforated support layer, and a negative ion generating layer arranged sequentially, as well as a negative ion generating device. The flexible heating mesh is generally mesh-like. The flexible perforated support layer is disposed between the flexible heating mesh and the negative ion generating layer and has a plurality of perforations. The negative ion generating device includes a plurality of negative ion emitting heads, which are mounted on the negative ion generating layer. The released negative ions pass through the perforations of the flexible perforated support layer and then diffuse outward through the mesh of the flexible heating mesh.

[0011] Furthermore, the flexible heating mesh is made of a flexible substrate composite conductive heating material.

[0012] Furthermore, the conductive components on the flexible heating mesh are provided with grounding terminals, one end of the grounding wire is connected to the grounding terminal, and the other end is connected to the equipment's main grounding terminal or the earth.

[0013] Furthermore, the flexible hollow support layer is made of air fiber material.

[0014] Furthermore, it also includes a base cover; the flexible hollow support layer and the negative ion generating layer are disposed inside the base cover, and the base cover is fixedly connected to the edge of the flexible heating mesh; the base cover is provided with several ventilation holes.

[0015] Furthermore, the base cover and the flexible heating mesh are fixedly connected by sewing, zippers, Velcro, or buckles.

[0016] Furthermore, a connecting support rod is fixedly installed on the flexible heating mesh.

[0017] Furthermore, it also includes an airbag, which is installed at the bottom of the base cover.

[0018] Furthermore, a conductive contact end is provided, which is electrically connected to the negative ion generator via a wire.

[0019] Because the present invention adopts the above-described technical solution, the present invention has the following advantages: 1. This invention employs a three-layer structure consisting of a flexible heating mesh, a flexible perforated support layer, and a negative ion generating layer, achieving a dual effect of heating and negative ion release. The perforations in the flexible perforated support layer and the mesh of the flexible heating mesh form a continuous negative ion diffusion channel. After release, negative ions can penetrate the flexible perforated support layer through the perforations and then diffuse to the application surface through the mesh of the flexible heating mesh. This avoids the problem in existing technologies where negative ions are trapped inside the membrane and cannot be released outward, significantly improving the negative ion output concentration and application effect.

[0020] 2. The three-layer structure of this invention is made of flexible materials, and the whole can bend and deform freely with the curve of the human body. It can be widely used in flexible physiotherapy products that need to conform to the human body, such as cushions, mattresses, chair backs, and physiotherapy protective gear, overcoming the defect of existing rigid boards that are not suitable for flexible products.

[0021] 3. This invention can be extended to chair back applications or airbag cushion applications. A connecting support rod can be installed on the flexible heating mesh fabric, which can be used directly as a chair back; an airbag can be installed at the bottom of the cover, which can be used as a mattress after inflation. It is convenient to inflate and deflate and has strong expandability. Attached Figure Description

[0033] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention; however, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] In the description of this invention, it should be noted that the terms "upper", "lower", "in", "out", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed when in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0035] A flexible structure for heating with negative ions, such as Figures 1-4 As shown, it includes a flexible heating mesh 1, a flexible hollow support layer 2, and a negative ion generating layer 3 arranged in sequence, as well as a negative ion generating device.

[0036] like Figure 3 As shown, the flexible heating mesh 1 is made of flexible substrate composite conductive heating material. The whole is in the shape of a mesh. It generates heat when energized, and the mesh structure provides a channel for negative ions to diffuse outward.

[0037] The flexible substrate of the flexible heating mesh fabric 1 can be selected from different types according to the needs of the actual application scenario: one type is a highly flexible substrate, such as polyester fiber cloth, nylon woven cloth, spandex blended cloth, etc., which is soft and thin overall and can be freely bent and conform to the curves of the human body, suitable for close-fitting applications such as cushions, mattresses, and physiotherapy protective gear; the other type is a semi-rigid support substrate, such as fiberglass mesh cloth, polypropylene mesh cloth, carbon fiber woven cloth, etc., which has a certain shape retention ability and support rigidity, and can return to the preset shape after bending and deformation, suitable for applications such as chair backs and backrests that require both fit and structural support. Both types of substrates can be combined with conductive heating materials to meet the comprehensive requirements of different products for flexibility, support and fit.

[0038] The conductive heating material of the flexible heating mesh fabric 1 can be achieved in several ways: First, graphene heating, where graphene conductive paste is coated or printed onto a flexible substrate to form a graphene heating layer. Graphene has excellent conductivity and far-infrared radiation characteristics, resulting in rapid heating and uniform heat distribution after energization, and also has additional benefits such as antibacterial properties and promoting blood circulation. Second, resistance wire heating, where metal resistance wires (such as nickel-chromium alloy wires, stainless steel wires, etc.) are woven or wound into the flexible substrate. When energized, the resistance wires generate heat, resulting in a simple structure, low cost, and good durability. Third, carbon fiber heating, using carbon fiber filaments or woven carbon fiber fabric as the heating element. Carbon fiber has stable resistance, uniform heating, good flexibility, and is resistant to bending. Fourth, conductive fiber fabric heating, using conductive fibers (such as silver-plated fibers, stainless steel fibers, etc.) interwoven with ordinary fibers to form a conductive heating mesh fabric. This fabric offers excellent flexibility, can directly contact human skin, and provides good wearing comfort. All of the above heating methods can be used individually or in combination to meet the requirements of different application scenarios regarding heating temperature, power density, flexibility, and cost.

[0039] More specifically, the conductive components of the flexible heating mesh 1 are pre-set with grounding terminals. One end of the grounding wire is firmly connected to the grounding terminal by means of fastening bolts, welding or crimping, and the other end is reliably connected to the equipment's main grounding terminal or the earth, ensuring that leakage current, static electricity and induced charge can be quickly conducted to the earth, ensuring the safe operation of the equipment.

[0040] A flexible, perforated support layer 2 is positioned between the flexible heating mesh 1 and the negative ion generating layer 3. It features several perforations through which negative ions diffuse. The flexible, perforated support layer 2 has a certain thickness and compression resilience, allowing it to withstand and distribute pressure applied by the user. This prevents the flexible heating mesh 1 from directly pressing against the negative ion emitter 301 on the negative ion generating layer 3, thus avoiding deformation or damage to the emitter 301 and ensuring its negative ion release function is not affected. Furthermore, the flexible, perforated support layer 2 maintains a certain distance between the flexible heating mesh 1 and the negative ion generating layer 3, creating an airflow space that provides a buffer for the accumulation and diffusion of negative ions. Simultaneously, the flexible, perforated support layer 2 is a flexible structure that deforms with the product when bent, without restricting the overall flexibility of the structure. This ensures that the three layers deform synergistically and consistently when the product conforms to the human body's curves.

[0041] Specifically, the flexible perforated support layer 2 can be made of air fiber material. Air fiber is a three-dimensional mesh elastic structure material made of thermoplastic elastomers (such as TPEE polyester or polypropylene) through melt spinning and irregular three-dimensional crimping and winding. It naturally forms a large number of interconnected pores, has excellent air permeability, and combines elastic cushioning and support functions. The whole structure can be bent and folded, meeting the requirements of flexible structure use. When air fiber is used as the flexible perforated support layer 2, its three-dimensional interconnected pore structure provides sufficient flow channels for the outward diffusion of negative ions. At the same time, its elastic recovery performance can buffer and protect the upper flexible heating mesh fabric 1, improving the overall user comfort and durability of the product.

[0042] The negative ion generator includes a high-voltage power supply module and several negative ion emitters 301 electrically connected to it. The high-voltage power supply module outputs a negative high voltage, and the negative ion emitters 301 generate corona discharge under the action of the negative high voltage to ionize the air and generate and release negative ions. Figure 4 As shown, several negative ion emitters 301 are mounted on the negative ion generating layer 3, evenly distributed on the surface of the negative ion generating layer 3. The released negative ions pass through the perforations of the flexible hollow support layer 2, and then diffuse outward to the use surface through the mesh of the flexible heating mesh 1, achieving the dual effect of heating and negative ion release. To ensure clarity and ease of understanding of the accompanying drawings, the circuit parts and conventional connecting wires are omitted in the drawings. The specific connection methods and working principles all adopt conventional technical means in this field, and will not be described in detail here.

[0043] The negative ion generating layer 3 is a flexible structure that can be bent and deformed according to the shape of the product without affecting the negative ion release function. It can be made of materials such as silicone rubber substrate, polyurethane (PU) foam substrate, and non-woven fabric substrate.

[0044] This flexible structure for heating negative ions is also equipped with a conductive contact end, which is electrically connected to the negative ion generator via a wire. The conductive contact end can be a patch or a wristband. When in use, the user places the conductive contact end in contact with the treatment area, so that the human body and the negative ion generator form a circuit. Under the action of the electric field, the negative ions migrate directionally towards the human body, continuously increasing the number of negative ions emitted and improving the therapeutic effect.

[0045] The dimensions shown in the attached diagram are for reference only. The actual product dimensions may be adjusted according to the specific application requirements.

[0046] The following are several specific embodiments to further illustrate the technical solution of the present invention. Example 1:

[0047] like Figures 5-6 As shown, it also includes a bottom cover 4, a flexible hollow support layer 2 and a negative ion generating layer 3, which are set inside the bottom cover 4. The bottom cover 4 and the edge of the flexible heating mesh 1 are fixedly connected by sewing, zippers, Velcro or buckles, etc., so as to surround and encapsulate the flexible hollow support layer 2 and the negative ion generating layer 3 inside, forming a complete integrated flexible functional body.

[0048] The base cover 4 is provided with several ventilation holes 401, which connect the inside of the base cover 4 with the outside air. On the one hand, it provides a heat dissipation channel for the negative ion generator and the negative ion generating layer 3, preventing internal heat accumulation from affecting the life of the device. On the other hand, during the process of the negative ion emitter 301 continuously ionizing the air and consuming the air inside the base cover 4, the ventilation holes 401 maintain the internal and external air pressure balance, prevent the formation of negative pressure inside the base cover 4, and ensure the continuous and stable operation of the negative ion generator.

[0049] The bottom cover 4 is made of flexible material, such as polyester fiber cloth, nylon cloth, Oxford cloth, non-woven fabric or TPU coated cloth. It is soft in texture and can bend and deform together with the flexible heating mesh cloth 1 to form a flexible encapsulation structure, which is suitable for different usage scenarios such as cushions, mattresses, and chair backs. Example 2:

[0050] To provide a practical application, as a seat component, based on Embodiment 1, a connecting support rod 5 is fixedly installed on the flexible heating mesh fabric 1. For example... Figure 7 As shown, the invention can be used as a chair back by connecting the support rod 5 to the chair frame; as Figure 8 As shown, both the chair back and the seat cushion are equipped with the negative ion heating flexible structure of the present invention, which is fixedly connected to the chair frame through the connecting support rod 5.

[0051] When the user sits down, their body is in close contact with the flexible heating mesh 1. The flexible heating mesh 1, located on the side facing the user, directly bears the body pressure. The flexible perforated support layer 2 and the negative ion generating layer 3, located inside the base cover 4, do not directly contact the body and do not bear the user's body pressure, effectively protecting the negative ion generating device from pressure damage and extending its service life. Simultaneously, the user's body enjoys a heating and warming effect. The negative ions continuously released by the negative ion emitter 301 diffuse outwards through the perforations of the flexible perforated support layer 2 and the mesh of the flexible heating mesh 1, allowing the user to continuously inhale negative ions while seated, achieving a dual effect of heating and therapeutic health care. Example 3:

[0052] To provide a practical application, as a mat, based on Embodiment 1, an airbag 6 is installed at the bottom of the base cover 4. The airbag 6 is a common inflatable support structure in the prior art, and its inflation / deflation method, valve structure, and sealing process all employ conventional techniques in the field, which will not be elaborated further here. Before inflation, the airbag 6 is in a flattened, contracted state (e.g., Figure 9 As shown), the overall thickness is thin, and the volume is small when folded, making it easy to store and carry; after inflation, the airbag 6 expands and unfolds (as shown). Figure 10 As shown in the figure, a uniform elastic support layer is formed at the bottom of the base cover 4, providing users with a comfortable support and cushioning effect. The user experience is close to that of a traditional spring mattress or latex mattress, and the inflation and deflation operation is simple to adapt to different firmness requirements.

[0053] When the user lies down, the flexible heating mesh 1 is located on the side of the user's body. Body pressure is shared and dispersed by the airbag 6 and the flexible perforated support layer 2. The flexible perforated support layer 2 and the negative ion generating layer 3 do not directly bear concentrated pressure, effectively protecting the structural integrity of the negative ion generating device. Simultaneously, the flexible heating mesh 1 generates heat when powered on, and the negative ion emitter 301 continuously releases negative ions. These negative ions diffuse towards the user's body through the perforations of the flexible perforated support layer 2 and the mesh of the flexible heating mesh 1. The user can simultaneously enjoy the dual effects of heating and warmth while resting. This embodiment can be widely applied to various scenarios such as home mattresses, car seat cushions, outdoor inflatable mats, and rehabilitation therapy mats. It is portable and flexible in use.
