Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric blankets, and more specifically, to a segmented electric blanket. Background Technology
[0002] Electric blankets, a common household heating device, are widely used to provide warmth to the human body during the cold season. Traditional electric blankets typically use a uniform heating method, that is, heating elements are arranged throughout the blanket to ensure even temperature distribution on the surface. However, with the increasing demand for comfort and personalization, segmented heating electric blankets have gradually emerged in existing technology. These electric blankets divide the heating area into multiple independent blocks, each with its own temperature control, thus adapting to the different temperature needs of different parts of the body. For example, the feet may require a higher temperature, while the abdomen or back requires a relatively lower temperature.
[0003] The original design of segmented heating electric blankets was to improve user comfort, but in actual use, this design has also exposed some problems. Due to the temperature difference between different sections and the lack of an effective temperature transition mechanism, users may feel obvious temperature changes when touching different sections. This sudden temperature change reduces the comfort of using the electric blanket. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a segmented electric blanket.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a segmented electric heating blanket, including a heating layer and a first heat-conducting pad and a second heat-conducting pad located above the heating layer. A plurality of heating blocks are spaced apart on the heating layer. Any of the first heat-conducting pads is located above the corresponding heating block. The bottom surface of the second heat-conducting pad is in contact with the top surface of two adjacent heating blocks.
[0006] The present invention is further configured such that: a protrusion is fixedly connected to the bottom surface of the second thermal pad, and the bottom surface of the protrusion abuts against the top surface of the heating layer.
[0007] The present invention is further configured such that each of the two side walls of the protrusion contacts the side wall of a heating block.
[0008] The present invention is further configured such that the second thermal pad has the same contact area with the two adjacent heating blocks.
[0009] The present invention is further configured such that both the first thermal pad and the second thermal pad are detachably connected to the heating layer.
[0010] The present invention is further configured such that both the first thermal pad and the second thermal pad are woven from bamboo fiber yarn.
[0011] In summary, this utility model has the following beneficial effects: the second heat-conducting pad is in contact with two heating blocks with different heating efficiencies at the same time, so that the temperature of the second heat-conducting pad is between the temperatures of the two adjacent first heat-conducting pads. The second heat-conducting pad acts as a transition, making the temperature change felt by the user smaller and improving the user's comfort. The first and second heat-conducting pads, which are woven from bamboo fiber yarn, have good breathability and antibacterial properties. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0017] Example: A segmented electric blanket, such as Figure 1 , Figure 2 As shown, it includes a heating layer 1 and a first thermal pad 2 and a second thermal pad 3 located above the heating layer 1. Several heating blocks 4 are arranged at intervals on the heating layer 1. Any first thermal pad 2 is located above the corresponding heating block 4. The bottom surface of the second thermal pad 3 is in contact with the top surface of two adjacent heating blocks 4.
[0018] Specifically, three heating blocks 4 are embedded in the heating layer 1, and heating wires are installed in the heating blocks 4. The three heating blocks 4 can output heat at different power levels. For the three first heat-conducting pads 2, each first heat-conducting pad 2 is only heated by one heating block 4. The second heat-conducting pad 3 is independent of the first heat-conducting pad 2, reducing the heat exchange between the first heat-conducting pad 2 and the second heat-conducting pad 3. The second heat-conducting pad 3 is in contact with two heating blocks 4 with different heating efficiencies at the same time, so that the temperature of the second heat-conducting pad 3 is between the temperatures of the two adjacent first heat-conducting pads 2. The second heat-conducting pad 3 acts as a transition, making the temperature change felt by the user smaller and improving the user's comfort.
[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a protrusion 5 is fixedly connected to the bottom surface of the second thermal pad 3. The bottom surface of the protrusion 5 abuts against the top surface of the heating layer 1. Each side wall of the protrusion 5 contacts the side wall of a heating block 4. The contact area between the second thermal pad 3 and two adjacent heating blocks 4 is the same.
[0020] Specifically, the protrusion 5 and the second heat-conducting pad 3 are integrally woven together. On the one hand, the protrusion 5 supports the second heat-conducting pad 3 and prevents it from sinking significantly. On the other hand, each side of the protrusion 5 abuts against a heating block 4, reducing the relative movement of the second heat-conducting pad 3 relative to the heating layer 1 and ensuring the structural stability of the electric blanket. The projected areas of the second heat-conducting pad 3 on both sides of the protrusion 5 are the same, ensuring that the second heat-conducting pad 3 can be evenly heated by the two heating blocks 4.
[0021] like Figure 1 , Figure 2 As shown, both the first heat-conducting pad 2 and the second heat-conducting pad 3 are detachably connected to the heating layer 1. Both the first heat-conducting pad 2 and the second heat-conducting pad 3 are woven from bamboo fiber yarn. Specifically, both the first heat-conducting pad 2 and the second heat-conducting pad 3 are detachably connected to the heating layer 1 via Velcro. The loop side of the Velcro is located on the heating layer 1. The detachable nature of the Velcro facilitates the cleaning of the first heat-conducting pad 2 and the second heat-conducting pad 3. The bamboo fiber yarn is a yarn made by twisting three bundles of bamboo fibers. Bamboo fiber has good breathability and antibacterial effect. The first heat-conducting pad 2 and the second heat-conducting pad 3, woven from bamboo fiber yarn, have good breathability and antibacterial properties.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
