[0018] The technical scheme in the embodiments of the utility model will be described below in a clear and complete manner in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0019] The utility model provides a kind of cloth wiring of heating blanket core as Figs. 1-2 As shown in the figure, comprising:

[0020] Main structure;

[0021] Main structure includes heating layer lining cloth 1 and heating wire 2;

[0022] Heating wire 2 is arranged on the outside of heating layer lining cloth 1 by cloth edge strip 3, cloth edge strip 3 is wrapped on the outside of heating wire 2, and cloth edge strip 3 is sewn on heating layer lining cloth 1 by sewing line 4;

[0023] The heat generating wire 2 is wrapped by the selvedge strip 3, which can not only avoid the direct contact between the heat generating wire 2 and the heat generating layer lining cloth 1, but also avoid the clamping of the two groups of heat generating layer lining cloth 1 on the heat generating wire 2, thereby saving a group of heat generating layer lining cloth 1. Then, the selvedge strip 3 is folded to wrap the heat generating wire 2, and the selvedge strip 3 can be sewn on the heat generating layer lining cloth 1 by using the single sewing thread 4, so as to avoid the need to pass the thread on both sides of the heat generating wire 2 to limit the heat generating wire 2, and the single thread can avoid damaging the heat generating wire 2 when the thread is passed, and the process is also simplified.

[0024] As shown in Fig. 1

[0025] The two ends of the heat generating wire 2 penetrate the selvedge strip 3 and extend outwardly from the heat generating layer lining cloth 1, and the middle section of the heat generating wire 2 is in an S-shaped distribution and the horizontal lines are arranged in parallel. By limiting the position relationship between the heat generating wire 2 and the selvedge strip 3, the joint of the heat generating wire 2 is avoided to be inside the selvedge strip 3, which can easily cause safety accidents. Meanwhile, the heat generating wire 2 in the S-shaped direction can better disperse the heat generated.

[0026] Further, as shown in Fig. 2

[0027] The outer side of the heat generating wire 2 is wrapped with a wire skin 5, and the cross-sectional area of the cavity formed by the selvedge strip 3 and the sewing thread 4 is greater than the cross-sectional area of the heat generating wire 2. By wrapping the wire skin 5 on the outer side of the heat generating wire 2, the heat generating wire 2 is avoided to directly contact with the selvedge strip 3 after generating heat, which can easily cause safety accidents. Meanwhile, when the space inside the selvedge strip 3 is greater than the cross-sectional area of the heat generating wire 2, the heat generating wire 2 can be conveniently threaded, and the heat can be dispersed inside to avoid local high temperature.

[0028] Preferably, as shown in Fig. 2

[0029] The selvedge strip 3 is arranged in a symmetrical folding manner, and the sewing thread 4 is located at the middle region of the folded selvedge strip 3. By folding the selvedge strip 3 to wrap the outer side of the heat generating wire 2, the sewing thread 4 on one side can be saved, and the selvedge strip 3 can be sewn on the heat generating layer lining cloth 1 by using the single sewing thread 4.

[0030] In specific use, the selvedge strip 3 is folded, and the sewing machine is used to sew the selvedge strip 3 in the middle position of the folded selvedge strip 3 on the heat generating layer lining cloth 1 by using the sewing thread 4. Then, according to the thread direction, an S-shaped shape is formed on the heat generating layer lining cloth 1, and then the heat generating wire 2 is inserted into the cavity of the folded selvedge strip 3.

[0031] ​​​Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
