Description

Technical Field

[0001] This utility model relates to the field of electrothermal film technology, specifically to an anti-leakage electrothermal film. Background Technology

[0002] An electrothermal film is a semi-transparent polyester film that generates heat when electricity is applied. It possesses numerous excellent properties and a wide range of applications. The core heating element is typically a conductive material such as a specially formulated conductive ink or carbon fiber filaments. These materials generate heat under the influence of an electric field. The electrode material is generally a metal current-carrying strip, primarily made of copper foil or silver paste. Its function is to connect the conductive materials, forming a circuit loop that allows current to flow smoothly through the electrothermal film. The substrate is mostly a specially formulated PET polyester film, possessing excellent insulation properties, flexibility, high-temperature resistance, and corrosion resistance. This protects the internal heating element and ensures the lifespan of the electrothermal film.

[0003] Utility model patent CN212588524U discloses a leakage-proof electric heating film, including a protective plate, an electric heating film disposed below the protective plate, and a mounting plate disposed below the electric heating film. The interior of the protective plate is a hollow interlayer, with strip-shaped openings on the outer walls at both ends. Several heat dissipation holes are formed on the surface of the protective plate, and an insulating plate is disposed within the internal interlayer of the protective plate, with several through holes on its surface. This leakage-proof electric heating film, through the upper and lower protective plates and the mounting plate, ensures the insulation of the electric heating film from the outside environment, preventing leakage when the surface of the electric heating film ages. Furthermore, when not in use, the heat dissipation holes can be blocked by moving the insulating plate, thus preventing external water from entering and damaging internal components. It also prevents accidental electric shock to operators when the power is on, ensuring safe operation of the equipment.

[0004] However, when this electric heating film is in use, it is protected by a protective plate and a mounting plate to prevent external electrical interference in case of leakage. However, when leakage occurs, it is difficult for users to detect, which can easily lead to fires. Moreover, the use of a rigid protective plate makes it impossible to fold the electric heating film during use. Therefore, a leakage-proof electric heating film is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a leakage-proof electric heating film that offers advantages such as maintaining the flexibility of the heating film while providing leakage protection. This solves the problem that when common electric heating films leak electricity, the insulation components provide protection, making it difficult for users to detect the leakage and increasing the risk of fire.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A leakage-proof electric heating film includes an electric heating layer, a control wire is fixedly installed on one side of the electric heating layer, and a leakage-proof component is provided on the electric heating layer;

[0008] The leakage protection component includes an automatic circuit breaker fixedly installed at one end of the control wire. The surface of the heating layer is covered with a metal braided mesh. A leakage wire is fixedly installed on one side of the metal braided mesh, and one end of the leakage wire is connected to the automatic circuit breaker.

[0009] Furthermore, a reset switch is fixedly installed on the surface of the automatic circuit breaker, and a current detector is fixedly installed inside the automatic circuit breaker.

[0010] Furthermore, a high-temperature resistant insulating film is adhered to the surface of the heating layer, and a metal braided mesh is adhered to the surface of the high-temperature resistant insulating film.

[0011] Furthermore, an external insulating film is adhered to the surface of the metal woven mesh, and a waterproof film is adhered to the surface of the external insulating film.

[0012] Furthermore, a controller is fixedly installed on one side of the automatic circuit breaker, and two power indicator lights are fixedly installed on the surface of the controller. A power cord is fixedly installed on one side of the controller.

[0013] Furthermore, five temperature sensors are attached to the side of the high-temperature resistant insulating film away from the heating layer, and the temperature sensors are connected to the controller via temperature measuring cables.

[0014] Furthermore, a temperature display screen is fixedly mounted on the surface of the controller, and a processor electrically connected to the temperature sensor is installed inside the controller. The temperature display screen is electrically connected to the processor.

[0015] Furthermore, a control sealing sleeve is fixedly installed on one side of the waterproof membrane, and a control wire passes through the control sealing sleeve; a leakage sealing sleeve is fixedly installed on one side of the waterproof membrane, and a leakage wire passes through the leakage sealing sleeve; a temperature measuring sealing sleeve is fixedly installed on one side of the waterproof membrane, and a temperature measuring cable passes through the temperature measuring sealing sleeve.

[0016] Compared with the prior art, this utility model provides a leakage-proof electric heating film, which has the following beneficial effects:

[0017] 1. This anti-leakage electric heating film, by setting an anti-leakage component on the electric heating layer, uses a metal braided mesh on the surface of the electric heating layer to conduct the current through the leakage wire when leakage occurs in the electric heating layer. After the automatic circuit breaker detects the current, it automatically cuts off the power and shuts off the electric heating layer, preventing the electric heating film from continuing to work after leakage. This solves the problem that when electric heating films leak, they are protected by insulating components, but users find it difficult to detect the leakage, which can easily lead to fires.

[0018] 2. This leakage-proof electric heating film uses multiple temperature sensors on the surface of a high-temperature resistant insulating film to detect the heating temperature at multiple points on the film and display it on a temperature display screen. When the temperature difference is too large, the control system inside the controller detects the abnormal heating and shuts off the power. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1 to 4 In this embodiment, a leakage-proof electric heating film includes an electric heating layer 1, a control wire 2 fixedly installed on one side of the electric heating layer 1, and a leakage-proof component provided on the electric heating layer 1.

[0026] The leakage protection component includes an automatic circuit breaker 3 fixedly installed at one end of the control wire 2. A metal braided mesh 4 covers the surface of the heating layer 1, and a leakage current conductor 5 is fixedly installed on one side of the metal braided mesh 4. One end of the leakage current conductor 5 is connected to the automatic circuit breaker 3. The metal braided mesh 4 surrounds the heating layer 1. When leakage occurs in the heating layer 1, the metal braided mesh 4 conducts the current to the leakage current conductor 5, which then transmits the current to the automatic circuit breaker 3. The automatic circuit breaker 3 detects the leakage current and automatically shuts off the power.

[0027] Secondly, a reset switch 6 is fixedly installed on the surface of the automatic circuit breaker 3, and a current detector is fixedly installed inside the automatic circuit breaker 3.

[0028] Specifically, the metal braided mesh 4 is wrapped around the heating layer 1. When the heating layer 1 leaks current, the metal braided mesh 4 conducts the current to the leakage wire 5, and the current is transmitted to the automatic circuit breaker 3 through the leakage wire 5. The current detector inside the automatic circuit breaker 3 detects the leakage current and automatically shuts off the power to prevent the heating layer 1 from continuing to leak current.

[0029] Please see Figure 3 and Figure 4 In this embodiment, a high-temperature resistant insulating film 7 is adhered to the surface of the heating layer 1, and a metal braided mesh 4 is adhered to the surface of the high-temperature resistant insulating film 7.

[0030] The metal woven mesh 4 has an outer insulating film 8 attached to its surface, and a waterproof film 9 is attached to the surface of the outer insulating film 8. The high-temperature resistant insulating film 7 provides the first layer of protection for the heating layer 1, the outer insulating film 8 provides the second layer of insulation protection, and the waterproof film 9 provides waterproof protection for the heating layer 1.

[0031] Please see Figure 1 and Figure 2 In this embodiment, a controller 10 is fixedly installed on one side of the automatic circuit breaker 3. Two power indicator lights 11 are fixedly installed on the surface of the controller 10, and a power cord 12 is fixedly installed on one side of the controller 10. The power indicator lights 11 light up green when the power is on normally and light up red when the power is off abnormally.

[0032] Five temperature sensors 13 are attached to the side of the high-temperature resistant insulating film 7 away from the heating layer 1. The temperature sensors 13 are connected to the controller 10 through a temperature measuring cable 14.

[0033] Secondly, a temperature display screen 15 is fixedly mounted on the surface of the controller 10. The controller 10 has a processor that is electrically connected to the temperature sensors 13 inside, and the temperature display screen 15 is electrically connected to the processor. Five temperature sensors 13 measure the temperature of the heating layer 1 at multiple points. After calculation by the processor, the average temperature is displayed on the temperature display screen 15. When the temperature difference between the points is too large, the controller 10 shuts off the power.

[0034] It should be noted that the temperature sensor 13 is model 04023FC sensor, which is small in size and accurate in measurement.

[0035] Finally, a control sealing sleeve 21 is fixedly installed on one side of the waterproof membrane 9, and a control wire 2 passes through the control sealing sleeve 21. A leakage sealing sleeve 51 is fixedly installed on one side of the waterproof membrane 9, and a leakage wire 5 passes through the leakage sealing sleeve 51. A temperature measuring sealing sleeve 141 is fixedly installed on one side of the waterproof membrane 9, and a temperature measuring cable 14 passes through the temperature measuring sealing sleeve 141.

[0036] The working principle of the above embodiment is as follows: the metal braided mesh 4 is wrapped around the heating layer 1. When the heating layer 1 leaks current, the metal braided mesh 4 conducts the current to the leakage wire 5, and the current is transmitted to the automatic circuit breaker 3 through the leakage wire 5. The automatic circuit breaker 3 detects the leakage current and automatically shuts off the power.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
