Abstract
Description
Technical Field
[0001] This utility model relates to the field of temperature regulation technology, specifically to a heating picture based on an electrothermal film. Background Technology
[0002] Heated radiators are a relatively new type of electric heating radiator that has emerged in recent years, serving both heating and decorative purposes. Current heated radiators fix the heating element to the outer casing, conducting heat through direct contact between the heating element and the casing, and then dissipating the heat generated by the heating element to the outside through the casing.
[0003] However, existing heated paintings suffer from low heating element temperatures and low heating power density, resulting in insufficient heating capacity per unit area. This means that large heated paintings can only power small rooms, leading to resource waste and increased heating costs for users. Therefore, we propose a more convenient and practical electric heating film-based heated painting to meet user needs. Utility Model Content
[0004] The purpose of this invention is to provide a heating painting based on an electrothermal film to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a heating picture based on an electrothermal film, comprising a picture frame: a mounting groove is provided on one side of the picture frame, and a light strip is installed in the groove; a groove is provided on the other side of the picture frame, and an aromatherapy box is inserted into the groove; a ventilation hole is provided on the top of the picture frame above the aromatherapy box; and magnetic strips are fixedly connected to both sides of the picture frame.
[0006] An electric heating film is embedded in the picture frame. The electric heating film includes, in sequence, a heating layer, an upper insulating layer, a buffer layer, a thermally conductive silicone sheet, a flame-retardant silicone layer, and a protective layer.
[0007] Furthermore, the heating layer is a graphene composite conductive film with a resistance range of 50-200Ω, powered by a low-voltage DC power supply, and its surface temperature is controllable within the range of 30℃-60℃.
[0008] Furthermore, the electrothermal film also includes an alarm module, which is electrically connected to the heating layer and is connected via Bluetooth. When the temperature exceeds a preset threshold or a short circuit is detected, an audible and visual alarm is triggered.
[0009] Furthermore, the protective layer is made of tempered glass or a high-temperature resistant ceramic coating with a light transmittance of 90% or higher, and the surface is coated with a hydrophobic and anti-fouling coating.
[0010] Furthermore, the magnetic strip is a neodymium iron boron permanent magnet, continuously distributed along the inner side of the frame, with a magnetic attraction force ≥5N, used for quick fixation to iron walls or brackets; the light strip is an RGB adjustable LED light strip, with color temperature and brightness controlled by a remote control or mobile APP.
[0011] Furthermore, the thermally conductive silicone sheet has a thickness of 0.5-1.2 mm and a thermal conductivity ≥3 W / (m·K).
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This heating painting based on an electrothermal film utilizes the electrothermal film's properties. During use, when a low-voltage DC power supply is connected, the graphene composite conductive film converts electrical energy into heat energy due to the resistance effect. The surface temperature is controllable within the range of 30℃-60℃. The heat is efficiently and evenly transferred to the artwork through a thermally conductive silicone sheet, achieving outward radiation. In this process, an insulating layer prevents current leakage, a buffer layer reduces mechanical stress, and a flame-retardant silicone layer prevents localized overheating and combustion. Simultaneously, an alarm module monitors the temperature and circuit status in real time. If overheating or a short circuit is detected, an audible and visual alarm is immediately triggered, and a warning is pushed via Bluetooth. This device forms a physical barrier through a multi-layered structure and monitors for abnormal temperatures or short circuits in real time, triggering audible and visual alarms and pushing warnings to mobile devices. It is highly practical and suitable for widespread adoption.
[0014] Meanwhile, the frame has a built-in RGB adjustable LED light strip to adapt to different scene needs; the top ventilation hole is combined with the aroma diffuser box to achieve simultaneous temperature heating and aroma diffusion. Attached Figure Description

[0019] 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.
[0020] Heated paintings are needed for indoor temperature control. The heated painting provided by this utility model is specifically designed for temperature control operations during indoor temperature regulation. When using this device for temperature control, the working status of the heating film 6 should be checked regularly. If any abnormality is found, use should be stopped immediately and a professional should be contacted for repair. Avoid using the heated painting in humid environments to prevent electric shock and other safety accidents. Do not place the heated painting near flammable materials to prevent fire. During use, avoid scratching the surface of the frame or the heating film 6 with sharp objects to avoid affecting its service life and safety. When cleaning the heated painting, disconnect the power supply first and wipe it gently with a soft, dry cloth. Avoid using wet cloths or chemical cleaners.
[0021] like Figures 1-3 As shown, this utility model provides a technical solution: a heated picture based on an electric heating film 6, including a picture frame 1: a mounting groove is opened on one side of the picture frame 1, and a light strip 2 is installed in the groove; a groove is opened on the other side of the picture frame 1, and an aromatherapy box 3 is inserted into the groove; a ventilation hole 4 is opened on the top of the picture frame 1 above the aromatherapy box 3; and magnetic strips 5 are fixedly connected to both sides of the picture frame 1.
[0022] The electric heating film 6 is embedded in the picture frame 1. The electric heating film 6 includes, in sequence, a heating layer 601, an upper insulating layer 603, a buffer layer 604, a thermally conductive silicone sheet 605, a flame-retardant silicone layer 606, and a protective layer 607.
[0023] like Figure 2 As shown, the magnetic strip 5 is a neodymium iron boron permanent magnet, which is continuously distributed along the inner side of the frame 1. The magnetic attraction force is ≥5N, which is used to quickly fix it to the iron wall or bracket. The light strip 2 is an RGB adjustable LED light strip 2, which can control the color temperature and brightness through a remote control or mobile APP.
[0024] It is important to note that during use, when the user adjusts the color temperature and brightness of the light strip 2 via remote control or mobile APP, the power supply circuit of the heating film 6 operates independently without being affected. If the user sets the target temperature via temperature control, the alarm module 602 compares the temperature of the heating layer with the set value in real time, dynamically adjusts the power supply to maintain a constant temperature, and continuously discharges the fragrance emitted by the aroma box 3 through the ventilation hole 4. At the same time, it promotes the micro-circulation of air inside and outside the picture frame 1, accelerates the diffusion of heat from the surface of the heating film 6 into the room, and finally fixes the picture frame 1 with the magnetic strip 5 to ensure that the heating film 6 is tightly attached to the wall and the bracket. The picture frame 1 has a built-in RGB adjustable LED light strip 2, which can be adapted to different scene needs. The top ventilation hole 4 is combined with the aroma box to realize the simultaneous function of temperature sensing heating and aroma diffusion.
[0025] like Figure 3As shown, the heating layer 601 is a graphene composite conductive film with a resistance range of 50-200Ω. It is powered by a low-voltage DC power supply, and the surface temperature is controllable within the range of 30℃-60℃. The heating film 6 also includes an alarm module 602, which is electrically connected to the heating layer 601. The alarm module 602 is connected via Bluetooth and triggers an audible and visual alarm when the temperature exceeds a preset threshold or a short circuit is detected. The protective layer 607 is tempered glass or a high-temperature resistant ceramic coating with a light transmittance ≥90% and a hydrophobic and anti-fouling coating on its surface. The thermally conductive silicone sheet 605 has a thickness of 0.5-1.2mm and a thermal conductivity ≥3W / (m·K).
[0026] It is important to note that during use, when a low-voltage DC power supply is connected, the graphene composite conductive film converts electrical energy into heat energy due to the resistance effect. The surface temperature is controllable within the range of 30℃-60℃. The heat is efficiently and evenly transferred to the art carrier through the thermally conductive silicone sheet 605, achieving outward radiation. In this process, the insulation layer prevents current leakage, the buffer layer 604 reduces mechanical stress, and the flame-retardant silicone layer 606 prevents local overheating from causing combustion. At the same time, the alarm module 602 monitors the temperature and circuit status in real time. If overheating or short circuit is detected, an audible and visual alarm is immediately triggered and a warning is pushed via Bluetooth. The hydrophobic and anti-fouling coating reduces the difficulty of cleaning and extends the service life.
[0027] Example 1: In a 20㎡ living room, the user installs the heated artwork on the iron decorative wall behind the sofa. It is quickly and firmly attached by magnetic strip 5. The user selects the APP to control the light strip 2 to a warm yellow color and adjust the brightness to 60% to create a cozy atmosphere. The heating film 6 is set to a temperature of 40℃. After the graphene composite conductive film 601 is powered on, the heat is evenly diffused to the artwork through the thermally conductive silicone sheet 605. The surface temperature is stabilized at 40℃±1℃. The heat is supplied to the sofa area through infrared radiation. The lavender essential oil in the aromatherapy box 3 is slowly released through the ventilation hole 4. The alarm module 602 monitors in real time. If the temperature at a certain point exceeds 60℃ (such as a local short circuit), the user immediately triggers an audible and visual alarm and cuts off the power to avoid fire risk.
[0028] Example 2: Office lunch break scenario. In a 15㎡ office workstation, the user hangs a heated picture on an iron partition. Using a remote control, the light strip 2 is set to cool white with 30% brightness to simulate natural light, and the heating film 6 is set to 35℃. After the heating layer 601 is activated, heat is evenly transferred through the buffer layer 604, and the surface temperature of the protective layer 607 is stabilized at 35℃±0.5℃. Gentle heating is provided to the workstation area through infrared radiation. The ventilation hole 4 releases peppermint essential oil from the aromatherapy box 3 to help refresh the mind. The alarm module 602 connects to a mobile phone via Bluetooth, allowing the user to remotely check the temperature status. If a circuit malfunction is detected, an alarm is immediately sent to the mobile phone and the power is cut off.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
