Description

Technical Field

[0001] This utility model relates to the field of sofa cushion technology, and more specifically, to an intelligent sofa cushion heating device. Background Technology

[0002] As people's living standards improve, the comfort and intelligence of furniture are receiving increasing attention. Sofas, as an important part of daily home life, must be designed not only for aesthetics and durability but also for comfort, meeting the needs of use in different environments and climates. Sofa cushions, as the part that directly contacts the user, play a decisive role in the overall experience. Especially in cold seasons, people often want to enhance comfort by heating their cushions; therefore, sofa cushions with heating functions have gradually become popular products in the market. With the development of smart home technology, how to make heating devices more intelligent, safe, and convenient has become one of the important research directions in the industry.

[0003] Currently, most sofa cushion heating devices on the market rely on manual control. Users need to manually turn the heating function on or off to improve comfort in cold environments. However, this manual control method has certain shortcomings, especially when users need to leave suddenly, they may forget to turn off the heating device, resulting in it being powered on for an extended period. This not only increases energy consumption but also increases the risk of safety hazards, such as overheating or short circuits. Furthermore, traditional heating devices lack intelligent sensing capabilities and cannot automatically adjust based on ambient temperature or the user's condition, making the user experience less intelligent.

[0004] Therefore, there is a need to provide an intelligent sofa cushion heating device to solve the problem that current sofa cushion heating devices are prone to causing safety hazards. Utility Model Content

[0032] Reference Figures 1 to 5 This utility model proposes an intelligent sofa cushion heating device, comprising:

[0033] A base 1, a backrest 101 is fixedly installed on the upper surface of the base 1, and armrests 102 are provided on both sides of the backrest 101. A control panel 103 is fixedly installed on the upper surface of one of the armrests 102.

[0034] Heating mechanism 2 includes a cushion 201 disposed above base 1. A heat-conducting plate 202 is connected to the bottom surface of the cushion 201. A groove 206 and a limiting groove 209 are provided on the upper end surface of the base 1. An infrared sensor 207 is installed in the groove 206. A pressure sensor 213 is installed in the limiting groove 209. A limiting rod 210 is slidably connected to the limiting groove 209. The upper end surface of the limiting rod 210 is fixedly connected to the heat-conducting plate 202.

[0035] The upper surface of the base 1 is provided with a heat conduction hole 208, and the bottom surface of the base 1 is fixedly provided with a housing 203. An electric heating rod 204 is installed inside the housing 203, and the electric heating rod 204 is electrically connected to a microcontroller 205.

[0036] In the above embodiment, the base 1 serves as the supporting structure for the entire device, and a backrest 101 is fixedly installed on its upper surface to provide support for the user and make the sitting posture more comfortable. Armrests 102 are provided on both sides of the backrest 101, making it convenient for the user to lean on or place their arms. A control panel 103 is fixedly installed on the upper surface of one of the armrests 102, allowing the user to manually adjust the working status of the heating device through the control panel 103, thereby improving ease of use.

[0037] The heating mechanism 2 includes a seat cushion 201 located above the base 1, with a heat-conducting plate 202 connected to the bottom surface of the seat cushion 201. The heat-conducting plate 202 can evenly distribute heat, raising the temperature of the entire seat cushion 201 and improving the heating effect. The upper surface of the base 1 has a groove 206 and a limiting groove 209. An infrared sensor 207 is installed in the groove 206, which detects the temperature of the heat-conducting plate 202 and sends a signal to the microcontroller 205 when the temperature reaches a set value, causing the heating mechanism 2 to stop working and preventing overheating. A pressure sensor 213 is installed in the limiting groove 209 and is slidably connected to a limiting rod 210. The upper surface of the limiting rod 210 is fixedly connected to the heat-conducting plate 202, allowing it to sense whether the user is sitting on the seat cushion. When the user leaves the seat cushion, the pressure sensor 213 detects a decrease in load and sends a signal to the microcontroller 205, causing the heating device to automatically shut off, preventing the user from forgetting to turn off the device due to an emergency and improving safety.

[0038] In addition, heat conduction holes 208 are provided on the upper surface of the base 1 to allow heat to be transferred more evenly to the surface of the cushion 201. A housing 203 is fixedly installed on the bottom surface of the base 1. An electric heating rod 204 is provided inside the housing 203. The electric heating rod 204 is used to heat the heat conduction plate 202 and is intelligently controlled by a microcontroller 205 to ensure temperature stability.

[0039] In summary, by incorporating an electric heating rod 204 inside the base 1, combined with the heat-conducting plate 202 and heat-conducting holes 208, the heating device can efficiently transfer heat, improving the heating efficiency of the seat cushion. The electric heating rod 204 heats the interior of the housing 203, raising its internal temperature. The heat is then evenly transferred to the seat cushion 201 via the heat-conducting plate 202, increasing the overall temperature of the seat cushion and providing a more comfortable heating experience for the user. Simultaneously, the infrared sensor 207 monitors the temperature of the heat-conducting plate 202 in real time, preventing overheating and improving the energy efficiency and lifespan of the device. Furthermore, the coordinated action of the pressure sensor 213 and the limit rod 210 enables load sensing on the seat cushion, preventing users from forgetting to turn off the heating device due to sudden emergencies, eliminating safety hazards, effectively reducing energy waste, and improving the device's intelligence and safety.
