Description

Technical Field

[0001] This utility model relates to the field of graphene technology, specifically to a graphene heating film that is easy to roll up. Background Technology

[0002] Graphene is an allotrope of carbon, in which carbon atoms are arranged in sp... 2 Hybrid bonding forms a single-layer hexagonal honeycomb lattice graphene. Graphene is commonly used in heating structures in electrical appliances. However, due to the fragility of graphene, it is necessary to avoid wrinkles when winding it up. This requires the use of graphene heating films that are easy to wind up. Therefore, existing easy-to-wind graphene heating films have been continuously innovated and developed. It can be seen that the current easy-to-wind graphene heating film basically meets people's needs, but some problems still exist.

[0003] For example, the patent document with announcement number CN215187452U discloses a graphene heating film that is easy to roll up. It includes a graphene heating film that is easy to roll up and relates to the field of graphene heating film technology. It aims to solve the problem that most existing graphene heating films are packaged in a cylindrical roll-up shape. They can be directly unfolded and used during installation, but the actual ground area may be larger or smaller than the number of films to be installed. The heating film body includes a main film sheet and an edge sealing tape, and the main film sheet and the edge sealing tape are combined and connected. The main film sheet includes a planar heating element and a PVC protective layer, and the PVC protective layer is disposed on both sides of the planar heating element. The PVC protective layer is bonded to the planar heating element. Graphene strips are provided on the outer surface of the planar heating element, and the graphene strips are fixedly connected to the planar heating element. Warp dividing lines are provided on the outer surface of the PVC protective layer, and there are three warp dividing lines. Through the three warp dividing lines, winding operations and folding operations can be performed. In actual use, the film can also be cut along the warp dividing lines, so as to be suitable for different laying combination methods.

[0004] However, in actual use, the graphene heating film is wrapped with a protective film. When the graphene film is rolled up, the lengths of the graphene film and the protective film are different, resulting in graphene wrinkles and damage to the graphene film. Therefore, there is an urgent need for a graphene heating film that is easy to roll up to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a graphene heating film that is easy to roll up, in order to solve the problem mentioned in the background art where the length of the protective film on the surface of the graphene film is inconsistent with the length of the rolled-up graphene film, resulting in wrinkles in the graphene film within the protective film.

[0006] To achieve the above objectives, this utility model provides the following technical solution, disclosing a graphene heating film that is easy to roll up, including a connecting plate, a soft rubber pad fixedly connected to one side of the connecting plate, a graphene heating pad body movably connected to the inner wall of the soft rubber pad, and one side of the graphene heating pad body fixedly connected to one side of the connecting plate.

[0007] The winding mechanism includes a first return spring, one end of which is connected to the inner wall of the soft rubber pad. A first magnetic stone is provided at one end of the first return spring, and a second magnetic stone is provided on the other side of the graphene heating pad body. One side of the first magnetic stone is movably connected to one side of the second magnetic stone.

[0008] As a preferred technical solution of this utility model, the back of the soft rubber pad is provided with fixing plates on both sides, the inner wall of the fixing plate is provided with a slot, the two sides of the connecting plate are fixedly connected with fixing blocks, the inner wall of the fixing blocks is provided with a movable groove, the inner wall of the movable groove is slidably connected with a locking block, and the bottom of the locking block is fixedly connected with a limit block.

[0009] As a preferred embodiment of this utility model, the back side of the card block is provided with a groove, and the inner wall of the groove is provided with a second reset spring.

[0010] As a preferred embodiment of this utility model, the card block is provided with sliders on both sides, and the sliders are slidably connected to the inner wall of the movable groove.

[0011] As a preferred embodiment of this utility model, a control panel is provided on one side of the top of the connecting plate, and buttons are provided on the surface of the control panel.

[0012] As a preferred embodiment of this utility model, a cable is provided on the other side of the connecting plate, a telescopic component is provided on the surface of the cable, and a plug is provided at one end of the cable.

[0013] As a preferred technical solution of this utility model, the soft rubber pad has grooves on both sides, and the graphene heating pad body has rails on both sides, with the surface of the rails slidably connected to the inner wall of the grooves.

[0014] As a preferred technical solution of this utility model, the soft rubber pad has a certain toughness and can still maintain its current state after heating. The soft rubber pad is made of PP material, and a nylon cloth is fixedly connected to one side of the top of the soft rubber pad, and the edge of one side of the nylon cloth is set on the top of the first magnetic stone.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by rolling the graphene heating pad body and the soft rubber pad onto the surface of the connecting plate, effectively avoids wrinkles in the graphene heating pad within the soft rubber pad when the lengths of the graphene heating pad and the soft rubber pad are the same, since the length of the graphene heating pad body is shorter than the length of the soft rubber pad. Furthermore, when flattening the graphene heating pad body and the soft rubber pad, the first magnetic stone on one side of the first return spring attracts the second magnetic stone, thereby pulling one side of the graphene heating pad body and flattening the graphene heating pad, further preventing wrinkles in the graphene heating pad and effectively extending the service life of the graphene heating pad.

[0017] 2. This utility model involves rolling the graphene heating pad body and the soft rubber pad onto the surface of the connecting plate, then pushing the locking block to engage the limiting block at the bottom of the locking block into the locking groove, thereby connecting and fixing the fixing plate and the fixing block. This prevents the graphene heating film from unraveling after being rolled up, thus effectively improving the rolling effect and efficiency of the graphene heating pad body.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , Figure 5 and Figure 6 A graphene heating film that is easy to roll up includes a connecting plate 1, a soft rubber pad 2 is fixedly connected to one side of the connecting plate 1, a graphene heating pad body 3 is movably connected to the inner wall of the soft rubber pad 2, and one side of the graphene heating pad body 3 is fixedly connected to one side of the connecting plate 1.

[0027] The winding mechanism includes a first return spring 5, one end of which is connected to the inner wall of the soft rubber pad 2. A first magnetic stone 6 is provided at one end of the first return spring 5, and a second magnetic stone 7 is provided on the other side of the graphene heating pad body 3. One side of the first magnetic stone 6 is movably connected to one side of the second magnetic stone 7.

[0028] When using a rollable graphene heating film, the soft rubber pad 2 and the graphene heating pad body 3 are laid flat. Since the soft rubber pad 2 wraps around the bottom and sides of the graphene heating pad body 3, and the graphene heating pad body 3 is shorter than the soft rubber pad 2, when both are laid flat, the first return spring 5 on one side of the inner wall of the soft rubber pad 2 moves the first magnetic stone 6 through its elastic force. At this time, the first magnetic stone 6 attracts the second magnetic stone 7, causing the movement of the first magnetic stone 6 to attract and move the second magnetic stone 7. The first magnetic stone 7 moves, and the movement of the second magnetic stone 7 flattens the graphene heating pad body 3. When the graphene heating pad body 3 and the soft rubber pad 2 are rolled up, the graphene heating pad body 3 is movably connected to the inner wall of the soft rubber pad 2. This allows the graphene heating pad body 3 to be gradually rolled up inside the soft rubber pad 2 during the rolling process. Furthermore, the movably connected relationship and the adsorption of the first magnetic stone 6 allow the graphene heating pad body 3 to adhere to the inner wall of the soft rubber pad 2, thereby avoiding wrinkles during rolling.

[0029] Please see Figure 4 , Figure 5 and Figure 6The soft rubber pad 2 has two fixing plates 8 on its back side. The inner wall of the fixing plate 8 has a slot 9. The two sides of the connecting plate 1 are fixedly connected to the fixing blocks 10. The inner wall of the fixing blocks 10 has a movable groove 11. The inner wall of the movable groove 11 is slidably connected to the locking block 12. The bottom of the locking block 12 is fixedly connected to the limit block 13. The back side of the locking block 12 has a groove 14. The inner wall of the groove 14 is provided with a second reset spring 15. The two sides of the locking block 12 are provided with sliders 16, and the sliders 16 are slidably connected to the inner wall of the movable groove 11.

[0030] After the soft rubber pad 2 and the graphene heating pad body 3 are rolled counterclockwise to the surface of the connecting plate 1, the locking block 12 is pushed to move relative to the locking block 12. Then, the limiting block 13 at the bottom of the locking block 12 is aligned with the locking groove 9 and the limiting block 13 is inserted into the locking groove 9. Then, the locking block 12 is released and the locking block 12 is reset by the second reset spring 15, so that the limiting block 13 at the bottom of the locking block 12 is inserted into the bottom of the fixing plate 8, thereby connecting the fixing plate 8 and the fixing block 10. After the fixing block 10 and the fixing plate 8 are connected, the rolled graphene heating pad body 3 and the soft rubber pad 2 are fixed.

[0031] Please see Figure 1 and Figure 4 A control panel 17 is provided on one side of the top of the connecting plate 1. Buttons 18 are provided on the surface of the control panel 17. Cable 19 is provided on the other side of the connecting plate 1. Telescopic component 20 is provided on the surface of the cable 19. Plug 21 is provided at one end of the cable 19. Slide grooves 22 are provided on both sides of the soft rubber pad 2. Slide rails 23 are provided on both sides of the graphene heating pad body 3. The surface of the slide rails 23 is slidably connected to the inner wall of the slide grooves 22. The soft rubber pad 2 has a certain toughness and can maintain its current state after heating. The soft rubber pad 2 is made of PP material. Nylon cloth 4 is fixedly connected to one side of the top of the soft rubber pad 2. The edge of one side of the nylon cloth 4 is provided on the top of the first magnetic stone 6.

[0032] Both the control panel 17 and the button 18 can adjust the heating temperature of this device. This adjustment method is the common method for adjusting the temperature of the existing graphene heating pad body 3. Since the surface of the cable 19 is provided with a telescopic component 20, and the telescopic component 20 has a certain elasticity, the cable 19 can be pulled to stretch the telescopic component 20, thereby extending the length of the cable 19 on one side. The graphene heating pad body 3 can slide in the slide groove 22 through the slide rails 23 on both sides.

[0033] Working principle: When using a graphene heating film that is easy to roll up, first flatten the soft rubber pad 2 and the graphene heating pad body 3. At this time, the first return spring 5 on one side of the inner wall of the soft rubber pad 2 drives the first magnetic stone 6 to move through the elastic force. Then, because the first magnetic stone 6 and the second magnetic stone 7 are attracted to each other, the movement of the first magnetic stone 6 attracts and drives the second magnetic stone 7 to move. The movement of the second magnetic stone 7 flattens the graphene heating pad body 3. The first magnetic stone 6 and the nylon cloth 4 on the top of the soft rubber pad 2 can block the movement space of the first magnetic stone 6, so as to avoid the first magnetic stone 6 from pinching the user when it moves.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
