Description

Technical Field

[0001] This utility model relates to the field of building drainage technology, and more specifically, to a snow melting electric heating film for gutters. Background Technology

[0002] A gutter, also known as a roof drain or roof gutter, is a horizontal or sloping channel structure on the top of a building. Located at the edge or center of the roof, it collects and guides rainwater to the drainage system. The primary function of a gutter is to collect rainwater from the roof and, through its shape and slope, guide it to drains or the sewer system, thus preventing water from accumulating on the roof or seeping into the building's interior. Furthermore, gutters provide waterproofing, helping to reduce the risk of water infiltration and preventing damage to the building structure and materials. Gutters are an important component of building drainage systems and are widely used in various building types, including residential, commercial, and industrial buildings. Through proper design and installation, gutter systems can effectively solve building drainage problems and protect building structures and property.

[0003] With the widespread application of gutter drainage systems in buildings, snow and ice tend to accumulate in the gutters during winter. If not melted and removed promptly, this can not only damage the roof structure but also cause backflow after freezing, posing a serious threat to building safety. Current gutter snow melting methods mostly use heating cables or electric heating tapes as heating elements. However, these heating elements have a small heating area and limited heating range, typically only 1-3 centimeters, while the width of the gutters is often much greater, resulting in poor snow melting efficiency. Therefore, a more efficient and energy-saving gutter snow melting solution is urgently needed. Utility Model Content

[0004] To address the shortcomings of existing methods, this utility model provides a gutter snow melting electric heating film. This electric heating film has a large heating area and a large snow melting area, which improves snow melting efficiency, while also ensuring safety and convenience in use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A gutter snow melting electric heating film includes a main film bag, inside which are arranged multiple sets of graphene heating elements. The left and right ends of the multiple sets of graphene heating elements are connected by copper electrode plates. The outer sides of the multiple sets of graphene heating elements are heat-fused and sealed with a layer of silicone. The upper ends of the copper electrode plates on both sides are connected to waterproof quick-connect male plugs via cables, and the lower ends are connected to waterproof quick-connect female plugs via cables. The specifications of the waterproof quick-connect male plugs are compatible with the specifications of the waterproof quick-connect female plugs.

[0007] Furthermore, two sets of spacers are symmetrically arranged on the rear surface of the main membrane bag, and a soft magnet is attached to the outer end face of the spacer.

[0008] Furthermore, the main membrane bag is made of PVC and is bag-shaped. The periphery of the main membrane bag is heat-sealed, and the connection between the cable and the main membrane bag is sealed by heat-pressing.

[0009] Furthermore, the main body membrane bag is hot-pressed and fused with sealed secondary body membrane bags on both the left and right sides. A flexible metal heat-conducting sheet is provided on the rear side of the graphene heating element, and the heat-conducting sheet is encapsulated in silicone. The heat-conducting sheet has equidistantly arranged heating fins on both the left and right ends, and the heating fins extend into the secondary body membrane bag.

[0010] Furthermore, the rear surface of the secondary membrane bag is flush with the rear surface of the main membrane bag, the material of the secondary membrane bag is the same as that of the main membrane bag, and both the outer surfaces of the secondary membrane bag and the main membrane bag are coated with an anti-oxidation coating.

[0011] Furthermore, two soft magnetic sheets are vertically attached to the rear surface of the equally spaced heating fins.

[0012] Furthermore, the multiple sets of graphene heating elements are arranged in a uniform structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The electric heating film for snow melting in gutters of this utility model is easy to install, has a fast snow melting speed, and low energy loss. Its surface heating temperature does not exceed 60℃. The product has flame-retardant and waterproof features, and its breakdown voltage can reach more than 3750V, which fully ensures the safety performance of snow melting in gutters.

[0015] 2. The electric heating film for snow melting in the gutter of this utility model adopts a waterproof quick plug connection, which can easily realize the parallel and series connection of products to meet various construction requirements. It not only facilitates the installation and disassembly of the electric heating film, but also ensures safe use in humid environments, prevents the risk of short circuit caused by water seepage, and does not require construction on the roof. It is simple to lay and connect the wires. It is convenient to use and can be reused.

[0016] 3. The electric heating film for snow melting in gutters of this utility model uses graphene heating elements as heating elements. It heats up evenly and quickly, which can significantly improve snow melting efficiency. Multiple sets of graphene heating elements are evenly arranged to ensure that the heating area of ​​the entire electric heating film is maximized, thereby covering a wider gutter area and solving the problem of limited heating range of existing heating elements.

[0017] 4. In this utility model, two sets of spacers are symmetrically arranged on the rear surface of the main film bag. The spacers maintain a certain distance between the electric heating film and the gutter, preventing the electric heating film from directly adhering to the gutter and helping air to flow from the bottom of the electric heating film, thus accelerating the snow melting speed.

[0018] 5. This invention utilizes a soft magnetic sheet to allow the heating film to adhere to the gutter surface, thereby enhancing the adhesion of the heating film and securing it in place. This helps prevent the heating film from falling off under wind or snow pressure, improving its stability. Furthermore, the soft magnetic sheet facilitates the installation and removal of the heating film. During installation, simply align the heating film with the gutter, and the soft magnetic sheet will automatically adhere to it. During removal, simply pull the heating film down gently; no additional fixing devices or tools are required.

[0019] 6. This utility model utilizes a heat-conducting sheet to transfer heat generated by the graphene heating element, enabling heat transfer to the heating fins. The heat is then dissipated through the heating fins, heating the gutter from both sides, further increasing the snow-melting area and improving snow-melting efficiency. Furthermore, the heating fins and the outer ends of the heat-conducting sheet are encapsulated in a secondary membrane bag, ensuring airtightness, while allowing the heating fins on both sides to be bent and deformed according to the shape of the gutter sides.

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] Example:

[0029] like Figures 1 to 6 As shown, a gutter snow-melting electric heating film includes a main film bag 3. Multiple sets of graphene heating elements 8 are arranged uniformly inside the main film bag 3. Graphene, as a highly efficient heat-conducting material, heats up evenly and quickly, significantly improving snow-melting efficiency. The uniform arrangement of the multiple sets of graphene heating elements 8 ensures maximum heating area of ​​the entire electric heating film, thus covering a wider gutter area and solving the problem of limited heating range in existing heating elements. The left and right ends of the multiple sets of graphene heating elements 8 are connected by copper electrodes 9. A layer of silicone 10 is heat-fused and encapsulated on the outside of the multiple sets of graphene heating elements 8. The upper ends of the copper electrodes 9 on both sides are connected by an electric... Cable 2 is connected to a waterproof quick-connect male plug 1, and its lower end is connected to a waterproof quick-connect female plug 5 via cable 2. The specifications of the waterproof quick-connect male plug 1 and the waterproof quick-connect female plug 5 are compatible. The setting of the waterproof quick-connect male plug 1 and female plug not only facilitates the installation and removal of the electric heating film, but also ensures safe use in humid environments and prevents the risk of short circuits caused by water seepage. This design solves the problem that existing gutter snow melting methods mostly use heating cables or electric heating tapes as heating elements. However, the heating area of ​​these heating elements is small and the heating range is limited, usually only between 1-3 cm, while the width of the gutter is often much larger than this, resulting in poor snow melting effect.

[0030] In this embodiment, two sets of spacers 11 are symmetrically arranged on the rear surface of the main film bag 3. The spacers 11 maintain a certain distance between the heating film and the gutter, preventing the heating film from directly adhering to the gutter and facilitating airflow from the bottom of the heating film, thus accelerating snow melting. A soft magnetic sheet 12 is attached to the outer end face of the spacer 11. The soft magnetic sheet 12 is magnetic and can be adsorbed onto the surface of the gutter, thereby enhancing the adhesion of the heating film to the gutter and fixing the heating film. This helps prevent the heating film from falling off under wind or snow pressure, improving its stability. In addition, the soft magnetic sheet 12 facilitates the installation and removal of the heating film. During installation, simply align the heating film with the gutter position, and the soft magnetic sheet will automatically adhere to the gutter; during removal, simply pull down the heating film gently, without the need for additional fixing devices or tools.

[0031] In this embodiment, the main film bag 3 is made of PVC and is bag-shaped. The perimeter of the main film bag 3 is heat-sealed, and the connection between the cable 2 and the main film bag 3 is sealed by heat-pressing. PVC has good waterproof and moisture-proof properties, which can ensure the overall sealing of the electric heating film and prevent moisture from seeping in and causing short circuits or damage. In addition, PVC material is relatively lightweight but strong enough, making the electric heating film more convenient and durable in transportation, installation and use.

[0032] In this embodiment, a sealed secondary membrane bag 4 is hot-pressed and fused to both sides of the main membrane bag 3. A flexible, bendable metal heat-conducting sheet 7 is provided behind the graphene heating element 8, and the heat-conducting sheet 7 is encapsulated in silicone 10. Heating fins 6 are equidistantly arranged at both ends of the heat-conducting sheet 7, and the heating fins 6 extend into the secondary membrane bag 4. The heat-conducting sheet 7 is used to transfer the heat generated by the graphene heating element 8 to the heating fins 6, and the heat is dissipated through the heating fins 6, heating the gutter from both sides, further increasing the snow melting area and improving snow melting efficiency. Furthermore, the outer ends of the heating fins 6 and the heat-conducting sheet 7 are encapsulated in the secondary membrane bag 4, ensuring airtightness, while allowing the heating fins 6 on both sides to be bent and deformed according to the shape of the gutter sides.

[0033] In this embodiment, the rear surface of the secondary membrane bag 4 is flush with the rear surface of the main membrane bag 3. This design facilitates the tight adhesion of the rear surface of the secondary membrane bag 4 to the inner side of the gutter. The secondary membrane bag 4 is made of the same material as the main membrane bag 3. Both the outer surfaces of the secondary membrane bag 4 and the main membrane bag 3 are coated with an anti-oxidation coating. The main function of the anti-oxidation coating is to prevent the secondary membrane bag 4 and the main membrane bag 3 from undergoing oxidation reactions due to prolonged exposure to air or other environmental factors such as ultraviolet rays and humidity, which would lead to a decline in material performance or changes in appearance. This coating helps to extend the service life of the product.

[0034] In this embodiment, a soft magnet sheet 13 is vertically attached to the rear surface of the equidistantly arranged heating fins 6. The soft magnet sheet 13 facilitates magnetic adsorption onto the inner side of the gutter, so that the heating fins 6 are tightly attached to the inner side of the gutter, preventing them from loosening due to wind or rain and snow, which would affect the snow melting effect. In addition, the soft magnet sheet 13 plays a role in positioning and fixing the heating fins 6, preventing the heating fins 6 from bending and deforming.

[0035] This utility model of gutter snow melting electric heating film features easy installation, fast snow melting speed, and low energy loss. Its effective heating area can reach more than 60%, and the surface heating temperature does not exceed 60℃. The product has flame-retardant and waterproof characteristics, and its breakdown voltage can reach more than 3750V, fully ensuring the safety performance of gutter snow melting.

[0036] The working principle of this type of electric heating film for snow melting in gutters is as follows: In actual use, the heating film is aligned with the gutter. Utilizing the magnetism of the soft magnetic sheet 12 on the outer end face of the spacer 11, the heating film automatically adheres to the bottom surface of the gutter. Simultaneously, the bending angle of the two auxiliary film bags 4 is adjusted so that they are attached to the inner side of the gutter via the internal soft magnetic sheet 13. Depending on the length of the gutter, multiple sets of heating films can be connected in series or parallel. The connection between the heating films is achieved using waterproof quick-connect male plug 1 and waterproof quick-connect female plug 5, and the position of the heating film is adjusted to ensure coverage of the entire area requiring snow melting. Then, the heating film is connected to the power line using the waterproof quick-connect male and female plugs. When snow melting is needed, the heating film is energized. The graphene heating elements 8 are evenly arranged inside the main film bag 3. After being connected and energized via copper electrodes 9, they rapidly generate a large amount of heat energy, achieving snow melting inside the gutter. Meanwhile, this heat energy is transferred to the heating fins 6 through the flexible metal heat-conducting sheet 7, and the heating fins 6 then dissipate the heat to the left and right sides of the gutter, achieving uniform heating of the gutter and improving snow melting efficiency.

[0037] In summary, this electric heating film for gutter snow melting can efficiently and safely achieve the snow melting function of gutters, improve snow melting efficiency, and ensure unobstructed gutter flow.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
