Description

Technical Field

[0001] The utility model relates to the technical field of graphene flexible electric heating films, in particular to a graphene heating film for outdoor camping. Background Art

[0002] Graphene flexible electric heating film has unique flexibility. The power supply mode is divided into two categories: AC and DC. The temperature is divided into three series: high temperature, medium temperature and low temperature. It is a fifth-generation electric heating film product with new advantages such as fast heating, high safety factor, easy use, and resistance to bending. Graphene flexible electric heating film is a high-tech product after processing of graphene materials. It is generally used for graphene floor heating, outdoor camping, health heating pads, heated tatami, electric heated kangs and sweat steaming rooms.

[0003] Graphene heating film is also often used for outdoor camping. When camping outdoors, the graphene heating film is easily disturbed by strong winds. For example, strong winds will cause the connection between the power supply wire and the electrode layer to be pulled and easily broken. The existing patent document with announcement number CN218124950U discloses a temperature-limited graphene flexible electric heating film, which uses a first graphene fiber and a second graphene fiber that heat independently to form a heating wire. When in use, the corresponding heating zone is firstly heated by the single first graphene fiber or the second graphene fiber, and the temperature of the corresponding heating zone is detected by the temperature acquisition electrode. When the temperature of the corresponding heating zone rises to the temperature threshold, the conduction state of the currently heated graphene fiber is turned off by the temperature control switch, so that the temperature of the heating zone drops, and the conduction of another graphene fiber is turned on to start heating. Before the temperature of the heating zone drops to the lower threshold of the optimal temperature, the other graphene fiber can heat the heating zone, and so on and so forth, the temperature of the heating zone is kept between the optimum temperatures, the amplitude of the change of the hot and cold temperatures of the heating zone is reduced, and the aging speed of the substrate layer is slowed down, and the service life of the electric heating film is improved.

[0004] Although the above-mentioned temperature-limiting graphene flexible electric heating film can solve the corresponding technical problems, the connection between the power input wire and the electrode layer is easily pulled by external force, resulting in loosening or even breaking of the connection between the two. This not only shortens the service life of the temperature-limiting graphene flexible electric heating film, but also poses certain safety hazards. Therefore, a graphene heating film for outdoor camping is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1

[0023] like Figure 1-4As shown in the figure, a graphene heating film for outdoor camping includes a graphene electrothermal film main body 1 and a protective clip 2 for preventing loosening at the wiring connection. The protective clip 2 is provided at the wiring connection of the graphene electrothermal film main body 1. The graphene electrothermal film main body 1 includes an electrothermal film 11 made of graphene material, and the electrode layer of the electrothermal film 11 is electrically connected to a wire 12. The protective clip 2 includes a base member 21 provided at the wiring connection of the electrothermal film 11 and the wire 12. A flipping member 22 is movably provided on the top of the base member 21. There are two symmetrically arranged connecting members 23 between the base member 21 and the flipping member 22 for connection and fixation. The base member 21 is provided with a support member 24 for assisting in supporting the wire 12.

[0024] It should be noted that the working principle of the electrothermal film 11 is the same as that of a temperature-limiting graphene flexible electrothermal film with the prior art publication number CN218124950U, so it will not be elaborated in this technical solution.

[0025] Working principle: Pass one end of the wire 12 through the inner cavity of the rubber sleeve 242, so that the rubber sleeve 242 plays a supporting role for the wire 12. Then penetrate the positioning post 231 from bottom to top through the inner cavity of the corresponding through hole 13, so that the bottom plate 211 is located at the bottom of the electrothermal film 11 and the side plate 212 is located on one side of the electrothermal film 11. Then turn the top plate 221 downward. The top plate 221 drives the convex block 222 to rotate in the inner cavity of the groove 213. The top plate 221 also drives the counterbore 235 and the positioning groove 232 to move synchronously until the top plate 221 rotates to the maximum extent, so that the base member 21 and the flipping member 22 form a U-shaped structure, which can thus play a vertical limiting role for the wiring connection of the electrothermal film 11 and the wire 12. At the same time, the top end of the positioning post 231 is inserted into the inner cavity of the corresponding positioning groove 232, and the preliminary connection operation of the base member 21 and the flipping member 22 can be completed, which can further play a horizontal limiting role for the wiring connection of the electrothermal film 11 and the wire 12, thereby achieving a protective effect on the wiring connection of the electrothermal film 11 and the wire 12. Finally, insert the screw 234 into the inner cavity of the counterbore 235 and screw it into the inner cavity of the screw hole 233 until the maximum extent, and the fastening operation of the base member 21 and the flipping member 22 can be completed, effectively preventing the protective clip 2 from falling off the graphene electrothermal film main body 1.

[0026] Through the combined use of the base member 21, the flipping member 22, and the connecting member 23, the present utility model can play a protective role for the wiring connection of the electrothermal film 11 and the wire 12, avoiding the phenomenon that the wiring connection becomes loose or even breaks due to the pulling of external forces on the wire 12. At the same time, the support member 24 can prevent the wiring connection of the electrothermal film 11 and the wire 12 from being bent significantly under the action of external forces, thereby effectively preventing the occurrence of cracks on the surface of the wire 12. This can not only extend the service life of the graphene electrothermal film main body 1 but also ensure the use safety of the graphene electrothermal film main body 1.

[0027] Furthermore, the bottom support 21 includes a bottom plate 211 disposed at the bottom of the electric heating film 11 , a side plate 212 is integrally formed on one side of the top of the bottom plate 211 , the bottom plate 211 and the side plate 212 form an L-shaped structure, and a groove 213 is opened on the top of the side plate 212 .

[0028] Furthermore, the flip member 22 includes a top plate 221 arranged on the top of the electric heating film 11, and a protrusion 222 adapted to the groove 213 is integrally formed on one side of the top plate 221. The protrusion 222 is rotatably connected to the inner wall surface of the groove 213 through a rotating shaft. The above design, through the coordinated use of the bottom support member 21 and the flip member 22, can play a role in vertically limiting the connection point between the electric heating film 11 and the wire 12.

[0029] Furthermore, the connecting member 23 includes a positioning column 231 fixedly connected to the bottom of the base plate 211, a positioning groove 232 adapted to the positioning column 231 is provided at the bottom of the top plate 221, and a through hole 13 for the positioning column 231 to pass through is provided on the electric heating film 11. According to the above design, when the positioning column 231 passes through the through hole 13 and is inserted into the inner cavity of the positioning groove 232, the connection point between the electric heating film 11 and the wire 12 can be horizontally limited, thereby effectively preventing the wire 12 from loosening or even breaking at the connection point due to the pulling of external forces.

[0030] Furthermore, a screw hole 233 is formed at the top of the positioning column 231 , and a screw 234 is threadedly connected to the inner cavity of the screw hole 233 . A countersunk hole 235 connected to the positioning groove 232 and matched with the screw 234 is formed at the top of the top plate 221 .

[0031] The diameter of the countersunk hole 235 is larger than the diameter of the positioning groove 232. The above design, through the coordinated use of the positioning column 231 and the screw 234, can form a T-shaped structure, effectively preventing the end of the positioning column 231 from detaching from the inner cavity of the positioning groove 232, and ensuring that the protective clip 2 can be fastened at the connection point between the electric heating film 11 and the wire 12.

[0032] Furthermore, the support member 24 includes a support sleeve 241 fixedly penetrated on the side plate 212, the wire 12 is placed through the inner cavity of the support sleeve 241, a rubber sleeve 242 is provided between the inner wall surface of the support sleeve 241 and the surface of the wire 12, and the rubber sleeve 242 is glued to the inner wall surface of the support sleeve 241. The above design can play a role of replicating support for the wire 12 through the support member 24, and effectively prevent the electric heating film 11 and the wire 12 from being bent significantly due to the action of external force at the connection point.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
