Description

Technical Field

[0001] This utility model relates to the field of electric blankets, and in particular to an automatic temperature-regulating electric blanket. Background Technology

[0002] Electric blankets are a common type of bed heating appliance, mainly composed of heating elements, a core, a control switch, and a power cord. They work by generating heat through the flow of current through the heating elements and distributing the heat evenly to the surface of the blanket, providing users with a warm and comfortable sleeping environment. Due to their ease of use and rapid heating, they are widely used in cold regions or winter home settings, especially suitable for areas without centralized heating, making them an important small household appliance for improving living comfort.

[0003] However, traditional electric blankets typically use simple temperature control settings, such as low, medium, and high, which makes it difficult for users to precisely adjust to the ideal temperature. This can easily lead to overheating or insufficient temperature, affecting the user experience and causing safety hazards due to prolonged high temperatures, thus reducing safety during use. To address these issues, we propose an automatic temperature-regulating electric blanket. Utility Model Content

[0004] The purpose of this invention is to provide an automatic temperature-regulating electric blanket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic temperature-regulating electric blanket includes an outer layer, a surface layer fixedly connected to the upper surface of the outer layer, a bottom layer fixedly connected to the bottom surface of the outer layer, a controller fixedly embedded in the outer surface of the outer layer, and ceramic fiber cloth, aerogel felt, a heating layer and flame-retardant non-woven fabric respectively disposed inside the outer layer. The upper surface of the aerogel felt has multiple detection holes, and a thermistor temperature sensor is fixedly installed on the inner bottom wall of each detection hole. Multiple silicone anti-slip protrusions are fixedly connected to the bottom surface of the bottom layer.

[0007] In a further embodiment, the upper surface of the flame-retardant nonwoven fabric is filled with a buffer layer, the upper surface of which is in contact with the bottom surface of the surface layer.

[0008] In a further embodiment, the cushioning layer is made of memory foam, and the surface layer is made of breathable and skin-friendly fabric.

[0009] In a further embodiment, a temperature display module is fixedly embedded on the outer surface of the controller, a switch button is fixedly embedded on the outer surface of the controller, and the detection end of each thermistor temperature sensor is in contact with the bottom surface of the heating layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention, through the setting of a heating layer and its cooperation with flame-retardant non-woven fabric, can efficiently transfer heat upwards. At the same time, the thermistor temperature sensor is in close contact with the bottom surface of the heating layer, which can accurately detect the temperature and transmit the data to the controller in real time. The controller automatically controls the current of the heating layer. When the actual temperature is lower than the set value, the temperature rises rapidly, and when the set value is reached, the heating stops immediately, avoiding excessively high or low temperatures, improving the user experience in winter, and also avoiding safety hazards caused by prolonged high temperatures, thus improving safety during use.

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] Please refer to Figures 1-4. In this utility model, an automatic temperature-regulating electric blanket includes an outer layer 1, which is made of wear-resistant non-woven fabric. A surface layer 2 is fixedly connected to the upper surface of the outer layer 1, and a bottom layer 3 is fixedly connected to the bottom surface of the outer layer 1. The bottom layer 3 is made of a composite material of TPU waterproof and breathable membrane and non-woven fabric. A controller 4 is fixedly embedded in the outer surface of the outer layer 1. The controller 4 has a built-in control chip and a solid-state relay, and a temperature adjustment button is also provided on its surface. The interior of the outer layer 1 contains ceramic fiber cloth 10, aerogel felt 6, a heating layer 7, and flame-retardant non-woven fabric 8. Multiple detection holes 11 are opened on the upper surface of the aerogel felt 6, and a thermistor temperature sensor 12 is fixedly installed on the inner bottom wall of each detection hole 11. Multiple silicone anti-slip protrusions 14 are fixedly connected to the bottom surface of the bottom layer 3. The heating layer 7 uses graphene composite heating wire, which can achieve rapid heating and uniform heating. It is wrapped with a high-strength aramid fiber woven layer and insulating tape to enhance flexibility and insulation. The bottom layer 3... The silicone anti-slip protrusions 14 on the bottom surface can prevent the electric blanket from sliding during use and improve its stability.

[0021] In a further embodiment, the upper surface of the flame-retardant nonwoven fabric 8 is filled with a buffer layer 9, the upper surface of the buffer layer 9 is in contact with the bottom surface of the top layer 2, the bottom surface of the ceramic fiber cloth 10 is fixedly connected to the upper surface of the bottom layer 3, the upper surface of the ceramic fiber cloth 10 is fixedly connected to the bottom surface of the aerogel felt 6, the upper surface of the aerogel felt 6 is in contact with the bottom surface of the heating layer 7, and the upper surface of the heating layer 7 is in contact with the bottom surface of the flame-retardant nonwoven fabric 8. The aerogel felt 6 and the ceramic fiber cloth 10 can form a heat insulation layer. The aerogel felt 6 has a low thermal conductivity, and the ceramic fiber cloth 10 is heat-resistant and flame-retardant. The two prevent excessive heat diffusion. The flame-retardant nonwoven fabric 8 is located between the heating layer 7 and the buffer layer 9, which not only assists in heat transfer but also plays a role in flame retardant protection.

[0022] In a further embodiment, the buffer layer 9 is made of memory foam, and the surface layer 2 is made of breathable and skin-friendly fabric. The buffer layer 9, made of memory foam, is filled between the flame-retardant non-woven fabric 8 and the surface layer 2. It can conform to the human body contour to provide support, relieve body pressure, and improve the comfort of use. The outer surface of the controller 4 is fixedly embedded with a temperature display module 13 and a switch button 5. The detection end of each thermistor temperature sensor 12 is in contact with the bottom surface of the heating layer 7. The controller 4 is embedded in the surface of the outer layer 1 and has a built-in control chip and solid-state relay. Temperature setting and power control are realized through the temperature adjustment button and the switch button 5. The temperature display module 13 provides real-time temperature feedback for convenient user operation.

[0023] The working principle of this utility model is as follows: When the electric blanket is working, current flows through the heating layer 7 to generate heat. The heat is transferred to the surface layer 2 through the flame-retardant non-woven fabric 8. Then, the temperature sensor 12 contacts the bottom surface of the heating layer 7, which can accurately detect the temperature and transmit the real-time temperature data to the controller 4. The controller can control the current flow of the heating layer 7 according to the preset temperature and environmental changes to achieve precise temperature control. When the user sets the temperature, the controller 4 receives the instruction. If the actual temperature of the heating layer 7 is lower than the set value, the controller 4 controls the heating layer 7 to start heating. When the temperature reaches the set value, heating stops. The temperature display module 13 provides real-time feedback of the temperature data.
