The power supply unit can also be arranged outside the shoe, so that the occupied volume in the shoe is reduced, and the scheme can better adapt to shoes with different styles and sizes.

Description

Technical Field

[0001] This utility model relates to the field of warming devices inside shoes, and in particular to a heated insole that can heat the soles or toes according to the user's needs. Background Technology

[0002] Because the extremities are far from the body's core and need to be easily accessible, their temperature is often lower than the core body temperature. However, in high latitudes or during severe cold seasons, the feet are less visible than the hands. When the cold environment causes decreased sensation in the extremities, it becomes even harder to notice frostbite and treat it promptly. Traditional foot warming methods include passive warming such as adding thickness to shoes and socks, as well as active warming methods that utilize chemical reactions or electrical energy to generate heat.

[0003] Chemical heating primarily utilizes an exothermic oxidation reaction to generate heat and provide warmth to the feet. Because the reaction is irreversible, and most people don't have the equipment to reverse it, chemical heating devices are mostly single-use consumables and cannot be reused. Furthermore, due to the chemical reaction, they are susceptible to the influence of catalysts and environmental factors, making temperature regulation difficult and increasing the risk of burns.

[0004] Active foot warmers powered by electricity typically consist of a heating element, a power source, and a simple switch. The heating element generates heat via a power source, providing warmth to the feet.

[0005] Taiwan Patent No. M589991 provides a structure for a heated insole that combines a graphene device with a power supply.

[0006] Taiwan Patent No. M527232 discloses a method of installing a heating unit and a control circuit board in the insole layer and energizing the heating unit to provide heat energy.

[0007] Existing electrically powered heated insoles integrate the control circuit board, heating element, and power supply into the insole, and the heating state is actively or passively controlled by the user's walking movements. This is because the heating elements in existing electrically powered heated insoles are mostly made of rigid materials, requiring ample space under the user's foot and a sufficiently thick cushioning layer to enhance wearing comfort. Otherwise, the wearer will experience a foreign body sensation under their feet, reducing wearing comfort.

[0008] Furthermore, because the heating element is made of rigid material, the heating area is limited to the bottom of the foot, preventing the heating of the toes. It can only raise the temperature enough to maintain the temperature of the toes as blood flows through the sole. The rigid material also means that during vigorous exercise, excessive impact can easily damage the heated insole, causing harm.

[0009] In view of the shortcomings of existing heated insoles, such as: the heating components increase the overall thickness of the insole; the rigid integrated electronic components reduce wearing comfort and are easily damaged by external forces; and the inability to adequately improve the warmth retention of the toes, this application actively and continuously develops solutions that can improve the above problems. Utility Model Content

[0010] This invention provides a flexible heated insole device. The flexible heating element itself, combined with the elasticity of the insole body, increases wearing comfort. Furthermore, the sheet-like heating element and the power supply unit located outside the shoe reduce the volume occupied by the heated insole inside the shoe. Wearers are not limited by shoe style, internal shoe space, or foot shape, and can freely install the device for warmth.

[0011] Another objective of this application is to utilize the elasticity and sheet-like structure of the flexible heating pad to fold back and cover the wearer's forefoot, especially the toes, to effectively cover and keep them warm.

[0012] The flexible heated insole device of this application includes: an insole body, a flexible heating element, and a power supply unit. The insole body is made of an elastic material; the power supply unit is electrically connected to a heating wire. The flexible heating element is also made of an elastic material, disposed on one side of the insole body, and has an insulating layer and a heating wire. The heating wire is disposed on the insulating layer and has a power supply interface, which is connected to the power supply unit via an electrical wire.

[0013] In a preferred embodiment of this application, the heating wire generates heat energy using electricity from a power supply unit. Furthermore, the flexible heating element is an elastic sheet material that, when disposed on one side of the insole body, can deform with the insole body, thereby reducing the wearer's discomfort.

[0014] In a preferred embodiment of this application, one end of the flexible heating element is a connecting portion, and the opposite end is a protruding portion. The insole body, depending on its position after being placed in the shoe, can be divided into a heel end near the ankle and a toe end near the toes. The connecting portion connects to the toe end of the insole body, and the protruding portion protrudes from the toe end.

[0015] In a preferred embodiment of this application, when the insole body is inserted into the shoe, the protrusion can be folded back towards the heel end, thereby allowing the flexible heating pad to cover the wearer's toes and improve the warmth retention effect.

[0016] In a preferred embodiment of this application, the flexible heating element further includes a pull tab disposed on the side of the protrusion away from the connecting portion. When the protrusion is folded back towards the heel end, the pull tab can extend along the inside of the shoe tongue to the outside of the shoe for the wearer to pull on, thereby fixing the position of the protrusion and preventing the wearer from pushing the protrusion towards the toes when putting on the shoe.

[0017] In a preferred embodiment of this application, the power supply unit is disposed on the outside of the shoe, thereby reducing the volume occupied by the overall flexible heated insole device inside the shoe.

[0018] Preferably, the wire is connected to the power supply unit via the inside of the heel of the shoe.

[0019] Preferably, the wire is connected to the power supply unit via the inside of the shoe tongue.

[0020] In a preferred embodiment of this application, the power supply unit includes a control module comprising a switch, a temperature control unit, and a timer. The switch controls the on / off state of the heating wire; the temperature control unit controls the temperature of the heating wire; and the timer controls the operating time of the heating wire.

[0021] The beneficial effects of this utility model are:

[0022] The advantage of this application lies in the fact that the flexible heating element replaces the rigid heating device of existing heated insoles, effectively reducing the overall thickness of the application and avoiding taking up space inside the shoe, thereby increasing the comfort when the wearer uses the application. In addition, since the flexible heating element can deform with the insole body, this application does not need to increase the thickness of the insole to reduce the feeling of foreign objects; it also eliminates concerns about damage to the structure or parts of the heated insole caused by the weight or movement of the non-wearing person during intense exercise.

[0023] Another advantage of this application is that the flexible heating element can be bent inside the shoe, thus covering the foot, especially the toes, which are difficult to heat with existing heating devices. By bending and covering the wearer's forefoot, the wearer's toes can be effectively kept warm. Attached Figure Description

[0047] To make the technical problems, technical solutions, and advantages of this utility model clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this utility model. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this utility model. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0048] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0049] Figures 1 to 7This is a schematic diagram of an embodiment of the present utility model. Figure 1 The first embodiment of this utility model, as shown in the top view, includes: an insole body 1, a flexible heating element 2, and a power supply unit 3. The insole body 1 is made of an elastic material; the power supply unit 3 is electrically connected to a flexible heating wire 22. The flexible heating element 2 is made of an elastic material, disposed on one side of the insole body 1, and has: an insulating layer 21 and a heating wire 22. The heating wire 22 is disposed on the insulating layer 21 and has a power supply interface 221, which is connected to the power supply unit 3 via a wire 31.

[0050] like Figure 1 and Figure 2 As shown in the schematic diagram of the first embodiment of this utility model, the heating wire 22 generates heat energy by means of electricity from the power supply unit 3. Furthermore, the flexible heating element 2 is an elastic sheet material, which can deform with the insole body 1 when it is disposed on one side of the insole body 1, thereby reducing the wearer's foreign body sensation.

[0051] Furthermore, the flexible heating element 2 can be slightly smaller than the insole body 1. When installed in a shoe, the flexible heating element 2 can be on top and the insole body 1 can be on the bottom, allowing the flexible heating element 2 to directly contact the wearer's foot. Alternatively, the insole body 1 can be on top and the flexible heating element 2 on the bottom, so that the flexible heating element 2 does not directly contact the wearer's foot.

[0052] like Figure 3 As shown in the top view of the second embodiment of this utility model, one end of the flexible heating element 2 is a connecting portion 201, and the other end is a protruding portion 202. The insole body 1, depending on its position after being placed in the shoe, can be divided into a heel end 12 near the ankle and a toe end 11 near the toes. The connecting portion 201 connects to the toe end 11 of the insole body 1, and the protruding portion 202 protrudes outward from the toe end 11.

[0053] like Figure 3 and Figure 4 As shown in the schematic diagram of the second embodiment of this utility model, when the insole body 1 is inserted into the shoe, the protrusion 202 can be folded back towards the heel end 12, so that the flexible heating plate 2 covers the wearer's toes and improves the warmth retention effect.

[0054] like Figure 5 A top view of the third embodiment of this utility model and Figure 6 As shown in the schematic diagram of the third embodiment of this utility model, the connecting part 201 can be disposed at the heel end 12 of the insole body 1, and the protruding part 202 still protrudes from the toe end 11. This allows the utility model to heat the entire sole of the wearer's foot while also covering the wearer's toes, maximizing the heat preservation effect.

[0055] like Figure 4 and Figure 6 As shown, the flexible heating element 2 also has a pull tab 23, which is disposed on the side of the protrusion 202 away from the connecting portion 201. When the protrusion 202 is folded back towards the heel end 12, the pull tab 23 can extend along the inside of the shoe tongue to the outside of the shoe for the wearer to pull on, thereby fixing the position of the protrusion 202 and preventing the wearer from pushing the protrusion 202 towards the toe end 11 when putting on the shoe.

[0056] like Figure 7 As shown in the schematic diagram of the power supply unit 3 in this embodiment of the present invention, the power supply unit 3 can be disposed on the outside of the shoe, thereby reducing the overall volume occupied inside the shoe. Figure 2 , Figure 4 as well as Figure 6 As shown, the wire 31 can be connected to the power supply unit 3 via the inside of the heel of the shoe; or it can be connected to the power supply unit 3 via the inside of the tongue of the shoe.

[0057] In detail, the power supply unit 3 can be charged by an external power source, or other mobile power sources can be installed on the outside of the shoe and connected to the power supply unit 3 via wire 31.

[0058] like Figure 7 As shown, the power supply unit 3 has a control module 32, which includes a switch 321, a temperature control unit 322, and a timer (not shown in the figure). The switch 321 is used to control the opening and closing of the heating wire 22; the temperature control unit 322 is used to control the temperature of the heating wire 22; and the timer controls the working time of the heating wire 22.

[0059] The above describes the preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this utility model, and these improvements and modifications are also within the protection scope of this utility model.
