Description

Technical Field

[0001] The present application relates to the technical field of clothing, and in particular to a heating element and heated clothing. Background Art

[0002] In cold weather or in cold environments, people generally stay warm by wearing down jackets, thick cotton coats, cotton socks, or other passive warmth products, or by using heating products like hand warmers that temporarily generate heat. However, passive warmth typically doesn't heat up quickly and is ineffective, while temporary heating products like hand warmers wear out over time and can't be used for extended periods or reused.

[0003] At present, there are some methods in the prior art for heating clothes by arranging electric heating elements on clothes. Such heated clothes can be actively heated and can keep warm stably for a long time. However, these heated clothes still have some problems and therefore have not been widely used. For example, the heating device cannot be well adapted to the surface of the clothes, resulting in the user either being unable to move the body as freely and flexibly as wearing ordinary clothes when wearing heated clothes, or being affected by the heating device during activities and having a strange feeling or discomfort.

[0004] In addition, clothes are easily stretched in an undirected manner during daily human activities, and the heating device is easily affected by the tension of the clothes, causing its wires to be broken or have poor contact. In addition, during the undirected stretching process, the heating device is also easy to fall off the surface of the clothes, so improvement is needed.

[0005] Application Contents

[0006] In response to the shortcomings of the existing technology, the present application provides a heating element and heated clothing, wherein the heating element has high strength and is easy to stretch, and its structure is designed according to the actual use of the clothing, so that the heated clothing with it is not only durable but also can improve the comfort of the user when wearing it.

[0007] This application is implemented through the following technical solutions:

[0008] A heating element is characterized in that it comprises a gasket and a heating wire, wherein the gasket is an elastic body made of stretchable fabric, and the heating wire is arranged on the gasket in a curved shape.

[0009] Furthermore, within a plane, the heating element generally extends along a first direction and a second direction, and the length of the heating element in the first direction is greater than its length in the second direction, and the heating wire extends along the length direction of the gasket.

[0010] Furthermore, the heating element includes a hollow area, and at least part of the gasket is arranged around the hollow area.

[0011] Furthermore, within a plane, the heating element generally extends along a first direction and a second direction, and a length of the heating element in the first direction is greater than a length of the heating element in the second direction.

[0012] Furthermore, the hollow area generally extends along the first direction.

[0013] Furthermore, the heating element includes at least two first gaskets extending substantially along the first direction, and the heating element also includes a connecting element extending substantially along the second direction, and the connecting element is used to connect adjacent first gaskets.

[0014] Furthermore, the connecting member is smoothly connected to the first gasket.

[0015] Furthermore, a hot melt adhesive layer is provided on the gasket.

[0016] A heated garment having any one of the above-mentioned heating elements, characterized in that the gasket is connected to the surface of the garment.

[0017] Furthermore, the gasket and the connecting piece are connected to the surface of the clothing.

[0018] Compared with the existing technology, the advantages of this application are:

[0027] The following is a further non-restrictive detailed description of the technical solution of the application in conjunction with the preferred embodiments and their drawings. In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present application, "multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and cannot be understood as limiting the present application.

[0028] like Figure 1 As shown, a heating element according to one embodiment of the present application includes a gasket 1 and a heating wire 2 disposed on the gasket 1. The gasket 1 is used to connect to the surface of clothing so that the heating element can adhere to the clothing surface. The heating wire 2 is used to generate heat to heat the clothing. The heating element is also provided with two wires 21 for connecting to the heating wire 2. In actual use, the heating wire 2 is electrically connected to an external power source (not shown in the figure) via the two wires 21, thereby enabling continuous heating or heat preservation of the clothing.

[0029] In this embodiment, the gasket 1 is an elastic body made of stretchable fabric, and the heating wire 2 is arranged on the gasket 1 in a curved shape. In this way, when the clothes are pulled, the gasket 1 is easily deformed along with the clothes, and because the heating wire 2 is arranged in a curved shape, it is also easy to deform as the clothes are stretched, so that the entire heating element is easy to stretch along with the clothes, which is convenient for the user to move. It is preferred to set the heating wire 2 to extend along the length direction of the gasket 1, so that it is easier for the overall shape of the heating wire to deform, especially when the gasket 1 is arranged in a strip shape. It should be noted that the stretchable fabric referred to in this application, at least refers to a fabric that can drive the gasket 1 to stretch synchronously when the human body drives the clothes to stretch during basic daily activities; or it can be understood that when the human body stretches the clothes during basic daily activities, the gasket 1 can allow the clothes to be stretched.

[0030] In this embodiment, the heating wire 2 is secured to the gasket 1 by sewing. This sewing method prevents the heating wire 2 from falling off the heating element during production and transportation. Of course, other securing methods can be used to secure the heating wire 2 to the gasket 1, as long as the heating wire 2 can be stably secured to the heating element.

[0031] The heating element of the present application is used to heat clothing, which can be items such as underwear, socks, insoles, belts, and waist bags. The following will take heated clothing as heated socks as an example to further elaborate on the heating element structure of the present application. Figure 2 and Figure 3 As shown, the heater 7 is fixed to the bottom of the sock 5. A hot-melt adhesive layer 13 is provided on the side of the gasket 1 near the heating wire 2. During production, the gasket can be glued to the sock surface using a hot pressing process, with the heating wire 2 positioned between the gasket and the sock fabric. By configuring the gasket 1 to be made of stretchable fabric and gluing it to the sock surface with the hot-melt adhesive layer 13, the gasket 1 can be perfectly adhered to the surface of the garment, deforming and stretching with the fabric. This arrangement allows the gasket 1 to almost become part of the fabric, reducing the restriction of the heater on the natural stretch of the garment and improving the wearer's comfort.

[0032] like Figure 4 and Figure 2 As shown, in this embodiment, a hollow area 11 is formed in the center of the heating element, and a gasket is arranged around the hollow area 11. When the heating element 7 is fixed to the bottom 51 of the sock, the gasket combines with the sock fabric to form a heating area on the sock, and the fabric of the bottom 51 of the sock can be exposed through the hollow area 11 in the center. This allows the clothing fabric to be placed in the center of the heating element 7. Because the gasket is glued to the clothing fabric, there are three layers of thickness at the connection between the gasket and the clothing fabric: clothing fabric, glue layer, and gasket. Therefore, the tensile properties of the connection are still weaker than those of the original clothing fabric. By providing the hollow area 11, when the clothing is stretched, the clothing is easily deformed in the hollow area, which facilitates the stretching of the clothing and further reduces the restriction of the heating element on the natural stretching of the clothing.

[0033] like Figure 4As shown, in order to further reduce the restraint of the heating element on the natural stretching of clothing, the heating element in this embodiment is arranged in a "runway circle" shape, which extends generally along the first direction a and the second direction b in the plane. The first direction a and the second direction b are generally perpendicular to each other, and its length in the first direction a is greater than its length in the second direction b. Specifically, the heating element includes two substantially parallel first gaskets 101, the two first gaskets 101 extending along the first direction, the two first gaskets 101 are spaced apart to form a hollow area 11 therebetween, and the heating wire 2 is arranged along the length direction of the first gasket 101. The heating element also includes connecting members 3 respectively arranged at both ends of the length direction of the first gasket, the connecting members 3 extending along the second direction b, and the connecting members 3 are used to connect the two first gaskets 101 into a whole.

[0034] Since clothes are subjected to non-directional tension due to human activities when worn, they are stretched non-directionally. Generally, the stretching direction (tension direction) of clothes can be divided into the first direction a and the second direction b. Figure 5 , when there is a force pulling the clothes along the first direction a (such as Figure 5 The pulling force f1, f2, f3) is generally along the length direction of the first gasket 101, so the heating element is easy to deform and the clothes are easy to be stretched, thereby reducing the restraint of the heating element on the clothes. Figure 6 , when there is a force pulling the clothes along the second direction b (such as Figure 6 Medium tension f5, f4), because the gasket and the clothing are bonded, and the direction of the tension is generally perpendicular to the extension direction of the first gasket 101, the bonding part is not easy to deform; at this time, the clothing is easy to deform in the hollow area 11, which is also easy to stretch the clothing and reduce the restraint of the heating element on the clothing. When the tension stretches the clothing roughly along the midline direction of the angle between the first direction and the second direction, it has been verified through practice that the deformation of socks and other clothing fabrics also mainly occurs on the clothing in the hollow area 11 and in the length direction of the first gasket 101, so the clothing is also easy to be stretched. Therefore, after the heating element structure of the present application is adapted to the clothing, it reduces the restraint on the natural stretching of the clothing as much as possible, and can give the wearer a sense of flexibility when wearing ordinary clothes.

[0035] In this embodiment, the connector 3 is integrally formed with the first gasket 101, that is, the connector 3 and the first gasket 101 are both part of the gasket 1, and the heating wire 2 extends along the length of the connector 3. In other embodiments not shown in the figures, the connector 3 can also be made of other fabrics (such as other than the aforementioned stretchable fabric) and connected to the first gasket 101 made of the stretchable fabric. The connection method can be the same as the existing connection method between fabrics, which will not be elaborated here.

[0036] Furthermore, in this embodiment, the connectors 3 are disposed at both ends of the first gasket 101 and are configured in an outwardly convex arc shape along the length of the first gasket 101. This allows for a smooth connection with the first gasket, thereby reducing stress between the gasket and the garment fabric during stretching and preventing breakage of the adhesive layer. In other embodiments not shown, the connectors 3 can also be attached to any location along the length of the first gasket 101, as long as two adjacent connectors are spaced apart to provide a hollow region 11 therebetween.

[0037] In this embodiment, the heating element is configured in a "runway circle" shape. Similar configurations, such as ellipses, can also be employed. This ensures that the length of the heating element in the second direction (b) is shorter than its length in the first direction (a), thereby ensuring both stretchability and the heating element's ability to heat the garment. In practical applications, for example, installing the heating element at the bottom of socks facilitates stretching for both large and small feet. When installed on clothing such as belts or neckbands, the heating element's length can be aligned with that of the belt, facilitating stretching. When installed on clothing or trousers, the heating element's length can be arranged generally along the length of the garment, with multiple heating elements spaced apart to achieve optimal heating. When installed on sleeves or trouser legs, hollowed-out areas can be placed at flexible locations such as elbows and knees to facilitate stretching.

[0038] The present application also provides a method for manufacturing the above-mentioned heated clothing. The method can be used to quickly manufacture heated clothing that is convenient for users to move around. The method specifically includes the following steps:

[0039] A hot melt adhesive layer 13 is provided on the gasket 1 made of stretchable fabric;

[0040] Fix the heating wire 2 to the gasket in a bent shape;

[0041] Lay the side of the gasket 1 having the hot melt adhesive layer on the surface of the clothing;

[0042] The hot-melt adhesive layer on the gasket is melted by a hot pressing process so that the gasket is bonded to the surface of the clothing.

[0043] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
