Description

A dielectric line sewing structure suitable for temperature regulating blanket Technical Field

[0001] The utility model relates to the technical field of temperature regulating blankets, in particular to a medium line sewing structure suitable for temperature regulating blankets. Background Art

[0002] Currently, the heating wires of electric blankets or the cooling water pipes of water-cooled blankets on the market are mainly sewn onto them through two processes: embroidery threading and quilting threading. Both processes have their advantages and disadvantages.

[0003] Embroidery threading is a common method used in the production of electric blankets or water-cooled blankets. This process involves combining the heating wire (or cooling water pipe) with the surface fabric of the electric blanket (or water-cooled blanket), sewing the heating wire (or cooling water pipe) and the fabric together using needle and thread. While this method can achieve a relatively tight connection between the heating wire (or cooling water pipe) and the electric blanket (or water-cooled blanket), it also has some drawbacks.

[0004] First, the embroidery process requires an embroidery machine, which can easily damage the heating wire or cooling water pipes, causing safety hazards such as short circuits and leaks. Embroidery machines also have relatively low production efficiency and high production costs. Second, the large amount of needles and thread required for embroidery increases the cost and weight of electric blankets or water-cooled blankets.

[0005] Another common process is quilting threading, which uses a quilting machine to quilt the upper and lower layers of fabric together to form a channel, and manually insert the heating wire (or cooling water pipe) into the channel. This method also has some disadvantages.

[0006] First, the heating wire (or cooling water pipe) used in quilting threading is prone to tangling, which not only affects the performance of the electric blanket (or water-cooled blanket) but also poses a safety hazard. Second, the manual threading process is relatively complex, which also increases production difficulty and cost.

[0007] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation.

[0009] The utility model aims to overcome the deficiencies of the prior art and provide a medium line sewing structure suitable for a temperature regulating blanket, which does not damage heat exchange medium strips during the sewing process and has relatively high sewing efficiency.

[0010] The utility model is realized through the following technical solutions:

[0011] In order to solve the above technical problems, the utility model provides a line sewing structure suitable for a temperature regulating blanket, including a blanket surface cloth, on which a heat exchange medium strip and a cloth strip are provided. The cloth strip is folded from the middle so that its two side edges are folded together and wrap the heat exchange medium strip, and the two side edges of the cloth strip are sewn to the blanket surface cloth by sewing.

[0012] In order to further solve the technical problem to be solved by the present invention, the present invention provides a medium line sewing structure suitable for a temperature regulating blanket, wherein the blanket cover cloth is the cover cloth on an electric blanket or a water cooling blanket.

[0013] In order to further solve the technical problem to be solved by the present invention, the present invention provides a medium circuit sewing structure suitable for a temperature regulating blanket, wherein the heat exchange medium strip is a heating wire or a cooling water pipe.

[0014] In order to further solve the technical problem to be solved by the present invention, the present invention provides a medium line sewing structure suitable for a temperature regulating blanket, in which a sewing thread for sewing the cloth strip and the blanket surface cloth is provided between the cloth strip and the blanket surface cloth for connecting the two, and the extension direction of the cloth strip is consistent with the extension direction of the heat exchange medium strip.

[0015] In order to further solve the technical problem to be solved by the present invention, the present invention provides a medium line sewing structure suitable for a temperature regulating blanket, wherein a gap H is provided between the heat exchange medium strip and the sewing thread.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] The uniqueness of the present utility model lies in that it cleverly wraps the heat exchange medium strip (heating wire or cooling water pipe) in a cloth strip, and then firmly sews the cloth strip to the blanket surface cloth of the temperature regulating blanket (electric blanket or water-cooled blanket). During the sewing process, it is only necessary to sew the cloth strip on the side away from the heat exchange medium strip to ensure the stability of the temperature regulating blanket. This design makes the sewing process simple and convenient, while also greatly improving production efficiency and reducing costs. Most importantly, due to the wrapping effect of the cloth strip, the heat exchange medium strip is not easy to knot or break, thereby reducing the risk of malfunction of the temperature regulating blanket during use. In addition, since the sewing position is on the cloth strip, there is a certain safety distance between the sewing position and the heat exchange medium strip, so it is not easy to damage the heat exchange medium strip during sewing, further improving the service life and safety of the temperature regulating blanket. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings, wherein:

[0019] Figure 1 is a schematic diagram of the three-dimensional structure of the utility model;

[0020] FIG2 is a partial enlarged view of point A in FIG1 . DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] As shown in Figures 1 and 2, a medium line sewing structure suitable for a temperature regulating blanket includes a blanket cover cloth 1, on which a heat exchange medium strip 2 and a cloth strip 3 are provided. The cloth strip 3 is folded from the middle so that its two side edges are folded together and wrap the heat exchange medium strip 2, and the two side edges of the cloth strip 3 are sewn to the blanket cover cloth 1 by sewing.

[0023] The blanket cover fabric 1 is the cover fabric of an electric blanket or a water-cooled blanket, i.e., the surface fabric of the electric blanket or the water-cooled blanket, and the heat exchange medium strip 2 is the heating wire of an electric blanket or the cooling water pipe of a water-cooled blanket.

[0024] Preferably, in order to increase the heating area or the inclined area, the heat exchange medium strips 2 are arranged on the carpet fabric 1 in a bent manner.

[0025] In the design of this temperature regulating blanket, the heat exchange medium strips 2 are the key components that determine the heating or cooling function of the blanket.

[0026] In an electric blanket, the heat exchange medium strips 2 are heating wires made of high-temperature-resistant material. These wires generate heat when powered, transferring warmth to the user. To ensure even heat distribution, the heating wires are designed to bend along the blanket fabric 1, while the fabric strips 3 secure them in place to prevent them from moving.

[0027] On the other hand, the heat exchange medium strips 2 used in water-cooled blankets are cooling water pipes. These pipes carry cooling liquid, which conducts heat away from the user's body, achieving a cooling effect. Like the heating wires, the cooling water pipes are wrapped in fabric strips 3 and sewn into the blanket fabric 1, ensuring they are comfortable and close to the user for maximum cooling.

[0028] The present invention can provide a more efficient, safe and convenient temperature regulation blanket (electric blanket or water-cooled blanket) user experience by cleverly combining the blanket surface cloth 1, the heat exchange medium strip 2 and the cloth strip 3. This not only protects the heat exchange medium strip 2, but also enhances the durability of the overall structure and the comfort of the user. Specifically, the blanket surface cloth 1 is the surface material of the temperature regulation blanket, which provides a comfortable touch and an aesthetically pleasing appearance. The heat exchange medium strip 2 is the core component of electric heating or water cooling, which can generate heat or take away waste heat, so that the temperature regulation blanket can warm the user or lower the temperature. The cloth strip 3 is a material that wraps the heat exchange medium strip 2, which can effectively protect the heat exchange medium strip 2 and prevent it from getting knotted or damaged.

[0029] In fact, the uniqueness of the present invention lies in that it cleverly wraps the heat exchange medium strip 2 in the cloth strip 3, and then firmly sews the cloth strip 3 to the blanket cover fabric 1. During the sewing process, it is only necessary to sew the cloth strip 3 on the side away from the heat exchange medium strip 2 to ensure the stability of the temperature-regulating blanket. This design makes the sewing process simple and convenient, while also greatly improving production efficiency and reducing costs. Most importantly, due to the wrapping effect of the cloth strip 3, the heat exchange medium strip 2 is not easy to knot, thereby reducing the risk of malfunction of the temperature-regulating blanket during use. In addition, because the sewing position is on the cloth strip 3, there is a certain safety distance between the sewing position and the heat exchange medium strip 2. Therefore, it is not easy to damage the heat exchange medium strip 2 during sewing, further improving the service life and safety of the temperature-regulating blanket.

[0030] In addition, since the heat exchange medium strip 2 is covered by the cloth strip 3, the user cannot feel any hard pipes or wires when using it, which provides a more comfortable use experience.

[0031] More specifically, the sewing thread 4 between the fabric strip 3 and the blanket cover 1 is an integral part of connecting the two materials. More importantly, the extension direction of the fabric strip 3 aligns with the extension direction of the heat exchange medium strip 2. This design allows the sewing needle to sew along the extension direction of the fabric strip 3 during the sewing process, making it more convenient for mechanized and automated sewing, greatly improving production efficiency.

[0032] More specifically, the present invention specifically sets a gap H between the heat exchange medium strip 2 and the sewing thread 4. This gap H ensures that during the sewing process, the sewing needle and thread maintain a sufficient distance from the heat exchange medium strip 2, thereby avoiding unnecessary damage to it. The reason for this design is that the heat exchange medium strip 2 is the core component of the temperature regulation blanket. If it is damaged, it may affect the heating or cooling effect and service life of the temperature regulation blanket, and may also cause safety problems such as leakage of electricity or liquid. Therefore, the present invention ensures the safety of the sewing process by setting a safety gap H design, while also ensuring the normal operation of the heat exchange medium strip 2.

[0033] Preferably, the cloth strip 3 can be made of insulating and flame-proof material, thereby improving the safety of the temperature regulating blanket during use and avoiding safety issues such as electric leakage, fire or liquid leakage.
