Technical Field
[0001] This utility model belongs to the technical field of bed heating products, specifically a bed warmer that can heat the entire surface of the bed. Background Technology
[0002] In cold weather, bed warmers are effective in helping people fall asleep quickly. However, current bed warmer products have several drawbacks. Traditional electric blankets often use heating wires powered by 220V high voltage, posing safety hazards such as electric shock and fire. They also tend to have uneven heating, leading to localized overheating or insufficient temperature. Newer heating blankets or mattresses made of carbon fiber or graphene address electrical safety issues, but still suffer from uneven temperature distribution and insufficient softness. Some bed warmers are complex in structure and expensive, hindering widespread adoption. Other heating products, such as hand-warming pillows, have limited functionality and cannot meet the need for full-surface bed warming. Existing products often rely on external power sources, lack intelligent control, cannot remotely preheat, and offer limited safety features. While these products provide some warmth in cold weather, the user experience is poor, resulting in an overall unsatisfactory effect. Therefore, this invention proposes a bed warmer that can heat the entire surface of the bed.
[0003] In view of the above situation and to overcome the shortcomings of the prior art, this utility model provides a bed warmer that can heat the entire surface, effectively solving the problems mentioned in the background.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a bed warmer capable of heating the entire surface, comprising a bed warmer body, a flexible carbon nanotube heating film, wires, a thin film control panel, a built-in power bank module, a thin silicone layer, a memory foam core, a control circuit, and a DC power input port. The bed warmer body includes a memory foam core, the entire outer surface of which is covered with a flexible carbon nanotube heating film. A thin silicone layer is also covered on the outside of the flexible carbon nanotube heating film. The flexible carbon nanotube heating film is connected to the control circuit via wires. The control circuit is connected to the thin film control panel, the DC power input port, and the built-in power bank module.
[0005] Preferably, the shape of the bed warmer body includes, but is not limited to, human-shaped, long strip-shaped, or fruit and vegetable-shaped.
[0006] Preferably, the elongated shape of the fruits and vegetables includes, but is not limited to, bananas, peppers, and eggplants.
[0007] Preferably, the flexible carbon nanotube heating film has a surface resistivity of <20 ohms.
[0008] Preferably, the thickness of the thin silicone layer is 0.5-2 mm.
[0009] Preferably, the control circuit includes a temperature control module, a duration control module, a wireless communication module, and a safety protection module.
[0010] Preferably, the temperature control module supports three temperature settings: 25°C, 30°C, and 35°C. The duration control module supports selection of durations of half an hour, 1 hour, and 2 hours; The wireless communication module can connect with a mobile app to enable remote temperature adjustment, duration setting, and timed heating functions; The safety protection module includes over-temperature protection, automatic power-off when the temperature is ≥50℃, overcurrent protection, and overvoltage protection.
[0011] Preferably, the built-in power bank module is embedded in the reserved cavity of the memory foam core, supports 5-12V output, and is equipped with a Type-C charging interface.
[0012] Preferably, the membrane control panel is installed on the side of the bed warmer body, and the membrane control panel is equipped with temperature adjustment buttons, duration selection buttons and power indicator lights.
[0013] Preferably, the temperature adjustment button and the duration selection button are respectively connected to the temperature control module and the duration control module in the control circuit.
[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a flexible carbon nanotube heating film as the core heating element, which can be stably driven under a low voltage of 5-12V, completely covering the outer surface of the memory foam core. After being powered on, it can achieve synchronous heating of the entire surface, avoiding the problem of local overheating or temperature blind spots in traditional electric heating wire products, ensuring overall warm coverage of the bed and significantly improving the bed warming effect. 2. The flexible carbon nanotube heating film of this invention radiates mid- to far-infrared rays with a wavelength range of 4-16μm during the heating process. This band of infrared rays is consistent with the vibration frequency of human cells, and can penetrate the skin surface to act on deep tissues, promote blood circulation and metabolism, relieve muscle tension, and has both heating and health auxiliary functions. 3. This new type of bed warmer uses a memory foam core, which has excellent slow rebound properties. It can deform evenly with pressure and conform to the curves of the human body, effectively dispersing pressure and avoiding the pressure on bones caused by traditional hard bedding. At the same time, it has outstanding heat storage properties, which can store the heat generated by the flexible carbon nanotube heating film and release it slowly, reducing heat loss, significantly reducing energy consumption, and improving energy efficiency. In addition, its good breathability can reduce stuffiness and provide users with a soft, close-fitting, and long-lasting comfortable experience. 4. The flexible carbon nanotube heating film of this utility model is covered with a thin silicone layer with a thickness of 0.5-2mm. The silicone material is food-grade and has a softness and elasticity close to human skin. When touched, it can simulate the warm and smooth texture of natural skin, solving the problem of the cold or rough touch of traditional heating products. Because the thickness of the thin silicone layer is controlled within the ultra-thin range of 0.5-2mm, it can quickly transfer the heat generated by the heating film with a heat loss rate of less than 5%. While ensuring a comfortable touch, it does not affect the heat transfer efficiency, achieving the dual effect of "soft touch" and "highly efficient heat transfer". 5. The built-in power bank module of this utility model is embedded in the reserved cavity of the memory foam core, supports 5-12V output, and is equipped with a Type-C charging interface, which can be charged by an external power source; the bed warmer also retains a DC power input port, which can be adapted to low-voltage power sources such as external power banks, realizing flexible switching between built-in power and external power sources, without relying on a fixed power source, making it more convenient to use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Example 1, by Figures 1-2The present invention includes a bed warmer body 1, a flexible carbon nanotube heating film 2, a wire 3, a thin film control panel 4, a built-in power bank module 5, a thin silicone layer 6, a memory foam core 7, a control circuit, and a DC power input port. The bed warmer body 1 includes a memory foam core 7, the entire outer surface of which is covered with the flexible carbon nanotube heating film 2. The flexible carbon nanotube heating film 2 is covered with a thin silicone layer 6. The flexible carbon nanotube heating film 2 is connected to the control circuit through the wire 3. The control circuit is connected to the thin film control panel 4, the DC power input port, and the built-in power bank module 5.
[0019] The memory foam core 7 provides a soft and comfortable experience and energy-saving benefits for the bed warmer. Made of slow-rebound memory foam, it boasts excellent slow-rebound properties: when subjected to pressure from the human body, it deforms evenly to conform to the body's curves; after the pressure is removed, it slowly returns to its original shape within 5-10 seconds (slow rebound rate ≥90%), effectively dispersing pressure and avoiding the pressure on bones felt by traditional hard bedding. Simultaneously, it exhibits outstanding heat storage characteristics, storing and slowly releasing the heat generated by the flexible carbon nanotube heating film 2, reducing heat loss, significantly lowering energy consumption, and improving energy efficiency. Furthermore, its excellent breathability reduces stuffiness, providing users with a soft, conforming, and long-lasting comfortable experience.
[0020] The flexible carbon nanotube heating film 2 is used as the core heating element, which can be stably driven under a low voltage of 5-12V. The heating film completely covers the outer surface of the memory foam core 7 and is tightly attached to the memory foam core 7 (with no bubbles or wrinkles on the attached surface). After being powered on, it can achieve synchronous heating of the entire surface, avoiding the problems of local overheating or temperature blind spots in traditional electric heating wire products, ensuring overall warm coverage of the bed and significantly improving the bed warming effect. At the same time, the flexible carbon nanotube heating film 2 radiates mid-far infrared rays with a wavelength range of 4-16μm during the heating process. This band of infrared rays is consistent with the vibration frequency of human cells, which can penetrate the skin surface and act on deep tissues, promote blood circulation and metabolism, relieve muscle tension, and have both heating and health auxiliary functions.
[0021] A thin silicone layer 6 with a thickness of 0.5-2mm is attached to the flexible carbon nanotube heating film 2. The silicone layer is made of food-grade silicone material, which has a softness and elasticity similar to human skin. When touched, it can simulate the warm and smooth texture of natural skin, solving the problem of the cold or rough touch of traditional heating products. Because the thickness of the thin silicone layer 6 is controlled within the ultra-thin range of 0.5-2mm, it can quickly transfer the heat generated by the heating film with a heat loss rate of less than 5%. While ensuring a comfortable touch, it does not affect the heat transfer efficiency, achieving the dual effect of "soft touch" and "highly efficient heat transfer".
[0022] The shape of the bed warmer body 1 includes, but is not limited to, human-shaped, long strip-shaped, and vegetable-shaped, to suit different usage scenarios and user preferences.
[0023] Long, narrow shapes of fruits and vegetables include, but are not limited to, bananas, peppers, and eggplants.
[0024] Flexible carbon nanotube heating film 2, surface resistance < 20 ohms.
[0025] The thickness of the thin silicone layer 6 is 0.5-2mm.
[0026] The control circuit includes a temperature control module, a duration control module, a wireless communication module, and a safety protection module.
[0027] The temperature control module supports three temperature settings: 25℃, 30℃, and 35℃. It also supports precise adjustment to these three temperature settings and is equipped with temperature indicator lights (green for 25℃, yellow for 30℃, and red for 35℃) to adapt to different ambient temperatures and individual comfort needs. The duration control module supports selection of half an hour, 1 hour, and 2 hours; users can set the working time according to their sleep habits, and the power will be automatically cut off after the set time, which saves energy and prevents the safety hazards caused by continuous high temperature all night. The wireless communication module can connect with a mobile APP to enable remote temperature adjustment, duration setting, and timed heating functions. The wireless communication module supports Bluetooth / BLE protocol and can connect with a dedicated mobile APP. Users can remotely adjust the temperature, set the working time, or start heating 5-10 minutes in advance through the APP. The safety protection module includes over-temperature protection (automatic power-off when the temperature is ≥50℃), overcurrent protection, and overvoltage protection; the full protection module includes over-temperature protection (automatic power-off immediately when the surface temperature of the bed warmer is detected to be ≥50℃), overcurrent protection (power-off when the current exceeds 1.2 times the rated value), and overvoltage protection (power-off when the voltage exceeds 12V), with multiple protections to ensure safe use.
[0028] The built-in power bank module 5 is embedded in the reserved cavity of the memory foam core 7, supports 5-12V output, and is equipped with a Type-C charging interface, which can be charged by an external power source; the bed warmer also retains a DC power input port, which can be adapted to low-voltage power sources such as external power banks, realizing flexible switching between built-in power and external power sources, without relying on a fixed power source.
[0029] The membrane control panel 4 is installed on the side of the main body 1 of the bed warmer. The membrane control panel 4 is equipped with temperature adjustment buttons, duration selection buttons and power indicator lights.
[0030] The temperature adjustment button and the duration selection button are respectively connected to the temperature control module and the duration control module in the control circuit.
[0031] Working principle: Assembly and testing are detailed below: 1. Select high-quality memory foam material and mold it according to the designed mold (human shape, banana, pepper, eggplant, etc.); test the rebound characteristics and heat storage characteristics of memory foam to ensure support, comfort and energy saving; after the production is completed, repair and clean the main body 1 of the bed warmer, remove surface defects and impurities, and reserve the installation cavity of the built-in power bank module 5 in the preset position. 2.

An insulating protective layer is pasted on the outer surface of the flexible carbon nanotube heating film 2. 3. Cut the flexible carbon nanotube heating film 2 according to the size of the bed warmer body 1 so that it can completely cover the surface of the memory foam inner core 7; 4. Use a special adhesive to evenly and firmly attach the flexible carbon nanotube heating film 2 to the surface of the memory foam core 7, ensuring that the flexible carbon nanotube heating film 2 and the memory foam core 7 are tightly bonded, avoiding air bubbles or wrinkles that may affect the heating effect. 5. Install the built-in power bank module 5 into the reserved cavity of the memory foam core 7, and connect it to the power input terminal of the control circuit via wire 3, ensuring a secure connection; simultaneously connect one end of wire 3 to the electrode of the flexible carbon nanotube heating film 2, and the other end to the input terminal of the control circuit, connecting the output terminal of the control circuit to the DC power input port; during the connection process, pay attention to the insulation treatment of wire 3 to avoid short circuits; test the circuit to ensure that the switching between the built-in power bank module 5 and the external power supply is normal, and that the current can pass through the heating film normally to achieve the heating function; connect the thin film control panel 4 to the control circuit so that the thin film control panel 4 can accurately control the temperature and duration of the bed warmer; debug the thin film control panel 4 to ensure that the various temperature levels and duration selection functions are normal; 6. Connect the thin-film control panel 4 and the wireless communication module (Bluetooth / BLE module) to the control circuit, and test the temperature adjustment button, duration selection button, power indicator and Bluetooth connection indicator of the thin-film control panel 4 to ensure that all functions are normal; at the same time, test the connection between the mobile APP and the wireless communication module to verify the accuracy of the remote temperature adjustment, duration setting and timed heating (5-10 minutes in advance start) functions. 7. Debug the safety protection module of the control circuit, simulate scenarios with temperature ≥50℃, current exceeding the rated value by 1.2 times, and voltage exceeding 12V, ensure that the circuit can automatically cut off the power, and verify the effectiveness of the protection function; 8. On the surface of the heated bed warmer body 1 with the heating film attached, evenly attach a thin silicone layer 6. The thin silicone layer has good flexibility and thermal conductivity, which can simulate the touch of human skin, while protecting the heating film from external damage. During the attachment process, pay attention to removing air bubbles in the silicone layer so that the thin silicone layer 6 is tightly attached to the flexible carbon nanotube heating film 2 and the heated bed warmer body 1.
