Description

Technical Field

[0001] This application relates to the field of foot warming patches, and in particular to a wearable foot warming patch. Background Technology

[0002] When the temperature is low, people's feet tend to cool down, causing discomfort. To warm their feet, people often stick heat packs on the soles of their feet, which provide warmth through the heat emitted by the heat packs.

[0003] When heat packs are applied to the soles of the feet, they can cause discomfort. Therefore, existing technologies often involve placing heated insoles inside shoes to increase the perceived temperature of the feet, thereby reducing the foreign body sensation and discomfort caused by the adhesive.

[0004] Specifically, please refer to patent CN207125401U, which discloses a heating insole. The insole includes a base layer with a heating device on it. The heating device comprises a piezoelectric generator, a rechargeable lithium battery, and a heating wire covered with insulation. The piezoelectric generator is located at the center of the rear end of the base layer and is electrically connected to the rechargeable lithium battery and the heating wire. The heating device also includes a control mechanism, comprising a temperature sensor and a controller. The input of the controller is connected to the temperature sensor, and the output is connected to the rechargeable lithium battery. A fixing layer is located above the heating device, and an SBS elastic layer is located above the fixing layer. Several massage protrusions are provided on the SBS elastic layer. This invention can release constant-temperature heat without external charging, achieving the function of heating and keeping the feet warm.

[0005] Regarding the aforementioned technologies, users need to place the heated insoles inside the shoes when using them, which makes it inconvenient for users. Summary of the Invention

[0006] To facilitate users in applying the heating element for warming their feet, this application provides a wearable foot warmer.

[0007] The wearable foot warmer provided in this application adopts the following technical solution:

[0008] A wearable foot warmer includes a heating pack and a wearable component. The heating pack emits heat upon contact with air, and the wearable component is elastic.

[0009] A foot-wearing cavity is formed between the wearable device and the heating pack, and the foot-wearing cavity is used to accommodate the user's foot.

[0010] The wearable component has a through-hole for wearing around the ankle, which allows the user's foot to be inserted into the foot wearing cavity.

[0011] When the foot-wearing cavity contains the user's foot, the user's ankle is worn through the ankle-wearing hole, and the inner surface of the wearable part elastically covers the instep, and the heating pack is in close contact with the sole of the foot.

[0012] By adopting the above technical solution, when a user needs to wear the wearable foot warmer, they insert their foot into the foot wearing cavity through the ankle wearing hole, with the sole of the foot retracted within the cavity and the ankle inserted through the ankle wearing hole. This allows the foot warmer to be worn through the wearing device. This prevents the heating pack from shifting due to foot movement, reduces the foreign body sensation associated with adhesive, and also makes it easier for users to use the foot warmer alone to raise foot temperature.

[0013] Optionally, the ankle wearing hole has an outward protrusion and an inward concave portion on its wall. When the user's foot is placed inside the foot wearing cavity, the outward protrusion is closer to the toes and covers the instep of the user than the inward concave portion, and the inward concave portion is closer to the heel and covers the back of the user's heel than the outward protrusion.

[0014] By adopting the above technical solution, when the user's ankle is put into the ankle hole, the outward convex part will cover the instep and the inward concave part will cover the back of the heel, so that the shape of the ankle hole is adapted to the shape of the user's foot.

[0015] Optionally, the ankle wearing hole has an enlarged portion and a reduced portion, the width of the enlarged portion being greater than the width of the reduced portion, and the enlarged portion being further away from the edge of the wearable foot warmer than the reduced portion.

[0016] By adopting the above technical solution, when the user's ankle is inserted into the ankle wearing hole, the ankle will be inserted into the enlarged part, making it less likely for the ankle wearing hole to obstruct the insertion of the ankle. At the same time, the narrowed part also helps to improve the fit between the hole wall and the ankle, thus making it less likely for the ankle to slip out of the ankle wearing hole.

[0017] Optionally, the width of the enlarged portion is 10-20 mm, and the width of the reduced portion is less than 10 mm.

[0018] By adopting the above technical solution, it is beneficial to ensure that there is enough space for the user's foot and ankle to wear through the ankle hole, and it is also convenient to ensure that the wearable device is securely wrapped around the user's heel.

[0019] Optionally, the ankle wearing hole is crescent-shaped.

[0020] By adopting the above technical solution, it is beneficial to improve the fit between the ankle wearing hole and the user's ankle, ensuring the comfort and stability of wearing.

[0021] Optionally, the heating pack includes a first surface layer and a second surface layer. The first surface layer is hot-pressed and fixedly connected to the second surface layer. A heating chamber is formed between the first surface layer and the second surface layer. The heating chamber contains heating powder, which emits heat when it comes into contact with air.

[0022] By adopting the above technical solution, it is beneficial to improve the connection strength between the first and second layers, making it less likely for the heating powder to leak from the heating pack.

[0023] Optionally, the heating powder is contained in a powder bag located within the heating chamber.

[0024] By adopting the above technical solution, the powder bag further seals the heating powder, making it less likely for the heating powder to leak.

[0025] Optionally, the heating pack includes a foot-wearing part and a heel-wearing part, wherein the width of the heel-wearing part is smaller than the width of the foot-wearing part;

[0026] When the user's foot is placed inside the foot-wearing cavity, the foot-wearing part fits snugly against the user's foot.

[0027] When the user's foot is placed inside the foot-wearing cavity, the heel-wearing part fits against the user's heel.

[0028] By adopting the above technical solution, the user's heel width is generally smaller than the width of the foot. The foot-wearing part and the heel-wearing part fit the foot and heel respectively, which is conducive to increasing the contact surface between the heating pack and the foot for heat transfer, and also makes it easier for the user to wear shoes when wearing the foot warmer.

[0029] Optionally, the ankle wearing hole is closer to the heel wearing part than the foot wearing part, the length of the foot wearing part is 50-150mm, and the width of the foot wearing part is 50-115mm;

[0030] The length of the heel fitting part is 40-60mm, and the width of the heel fitting part is 40-60mm.

[0031] By adopting the above technical solution, it is beneficial to ensure the comfort of the user's foot when it is placed in the foot-wearing cavity.

[0032] Optionally, the length-to-width ratio of the foot-wearing portion is 1.1-1.5.

[0033] By adopting the above technical solution, it is beneficial to further ensure the comfort of the user's foot when it is placed in the foot-wearing cavity.

[0034] Optionally, the heel wearing part is rectangular, and the rear end of the foot wearing part is fan-shaped.

[0035] By adopting the above technical solution, it is easier for users to wear shoes when wearing foot warmers, reducing the occurrence of foot warmers hindering the wearing of shoes.

[0036] Optionally, the material of the wearable device is woven fabric or nonwoven fabric.

[0037] By adopting the above technical solution, it is beneficial to improve the comfort of the user's foot when it is placed inside the foot cavity.

[0038] Optionally, the foot-wearing cavity is provided through the front end of the wearable piece, and when the user's foot is housed inside the foot-wearing cavity, the user's toes are located outside the foot-wearing cavity.

[0039] By adopting the above technical solution, it is beneficial to reduce the obstruction of the user's foot by the heating pack during the movement of the user's foot inside the foot cavity, and to make the user's toes less likely to bend due to the hardness of the heating pack.

[0040] Optionally, the front end of the wearable device and / or the front end of the heating pack are arranged straight along the width direction.

[0041] By adopting the above technical solution, the heating pack can be used to reduce the impact of bending of the user's feet or toes.

[0042] In summary, this application includes at least one of the following beneficial technical effects:

[0043] 1. When a user needs to wear the wearable foot warmer, they insert their foot into the foot wearing cavity through the ankle wearing hole, ensuring the foot is placed inside the cavity and the ankle is inserted through the ankle wearing hole. The foot warmer is then worn through the wearing device. This prevents the heating pack from shifting due to foot movement, reduces the discomfort associated with sticking, and allows users to use the foot warmer alone to raise foot temperature.

[0044] 2. When the user's ankle is put through the ankle hole, the outward protrusion will cover the instep and the inward concave part will cover the back of the heel, so that the shape of the ankle hole is adapted to the shape of the user's foot.

[0045] 3. When the user's ankle is threaded through the ankle hole, the ankle will pass through the enlarged portion, making it less likely for the ankle hole to obstruct the insertion. At the same time, the narrowed portion also helps to improve the fit between the ankle hole wall and the ankle, thus making it less likely for the ankle to slip out of the ankle hole;

[0046] 4. It helps reduce the obstruction of the user's feet by the heating pack during movement inside the foot cavity, making the user's toes less likely to bend due to the hardness of the heating pack. Attached Figure Description

[0056] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0057] Example 1:

[0058] Embodiment 1 of this application discloses a wearable foot warmer. (See also...) Figure 1 and Figure 2 The wearable foot warmer includes a heating pack 1 and a wearable component 2. Combined with... Figure 3The heating pack 1 includes a first surface layer 11 and a second surface layer 12. The first surface layer 11 is fixedly connected to the second surface layer 12. In this embodiment, the first surface layer 11 and the second surface layer 12 are fixedly connected by an ultrasonic hot-pressing process. A heating chamber 101 is formed between the first surface layer 11 and the second surface layer 12. The heating chamber 101 is filled with heating powder. When the heating powder comes into contact with air, it undergoes physical changes and / or chemical reactions and releases heat, thereby allowing the user to increase the perceived temperature of their feet using the heat released by the heating pack 1. In this embodiment, the heating powder includes iron powder, activated carbon, and mugwort powder, thereby releasing heat through the oxidation of the iron powder and providing heat therapy through the mugwort powder.

[0059] Both the first layer 11 and the second layer 12 are made of flexible materials and have several perforated vents (not shown in the figure), such as woven fabric and / or nonwoven fabric. The inner diameter of each vent is smaller than the particle size of the heating powder, thereby facilitating the contact between the heating powder and the air outside the heating chamber 101 through the vents and preventing the heating powder from leaking out of the heating pack 1. In addition, in this embodiment, both the first layer 11 and the second layer 12 are made of non-elastic nonwoven fabric, and when the user wears the wearable foot warmer, the first layer 11 faces and adheres to the sole of the user's foot, while the second layer 12 faces away from the sole of the user's foot.

[0060] Reference Figure 4 The heating pack 1 includes a foot-mounted part and a heel-mounted part. The heel-mounted part is rectangular, and the rear end of the foot-mounted part is fan-shaped. The width D2 of the heel-mounted part is smaller than the width D1 of the foot-mounted part. When the user uses the foot warmer, the foot-mounted part fits against the bottom of the user's foot, and the heel-mounted part fits against the bottom of the user's heel.

[0061] The length L1 of the foot-mounted part is 50-115mm, and the width D1 of the foot-mounted part is 50-90mm, with the ratio of length L1 to width D1 being 1.1-1.5. The length L2 of the heel-mounted part is 60-70mm, and the width D2 of the heel-mounted part is 50-90mm, with the ratio of length L2 to width D2 being 0.6-0.9.

[0062] For example, in this embodiment, the foot-wearing part is rectangular, and its length L1 is set to 108 (±2) mm, its width D1 is set to 88 (±2) mm, and the ratio of its length L1 to its width D1 is set to 1.227 (±0.06). The length L2 of the heel-wearing part is set to 66 (±2) mm. One end of the heel-wearing part is rectangular and the other end is a 180° fan shape, and its width D2 is set to 88 (±2) mm, and the ratio of its length L2 to its width D2 is set to 0.75 (±0.05). Therefore, the foot-wearing part and the heel-wearing part are more suitable for the user's feet, and it is easier for the user to wear shoes while using the foot warmer, reducing the occurrence of situations where the width of the heel-wearing part is too large and makes it difficult to wear shoes.

[0063] Reference Figure 1 The wearable component 2 is fixedly connected to the heating pack 1. In this embodiment, the wearable component 2 is specifically heat-pressed and fixedly connected to the first surface layer 11, and the front end of the wearable component 2 is flush with the front end of the foot-wearing part. The material of the wearable component 2 is elastic and can be woven fabric or non-woven fabric. In this embodiment, the material of the wearable component 2 is elastic non-woven fabric.

[0064] Reference Figure 5 and Figure 6 A foot-wearing cavity 3 is formed between the wearable component 2 and the first surface layer 11, which is used to accommodate the user's foot. In this application, the shape of the foot-wearing cavity 3 for accommodating the foot is adapted to the foot, so that the wearable component 2 covers the entire or part of the foot, and the hole wall of the foot-wearing cavity 3, that is, the surface of the wearable component 2 facing the first surface layer 11 and the surface of the first surface layer 11 facing the wearable component 2, are both tightly or loosely fitted to the user's foot, so that the wearable component 2 is not easily detached from the user's foot.

[0065] The foot-wearing cavity 3 is disposed through the front end of the wearable component 2, and the front end of the wearable component 2 and / or the front end of the heating pack 1 are disposed flat. Specifically, in this embodiment, the front ends of the wearable component 2 and the heating pack 1 are both disposed flat and flush with each other, so that when the user uses the foot warmer, that is, when the user's foot is placed inside the foot-wearing cavity 3, the toes can extend to the outside of the foot-wearing cavity 3 and the heating pack 1, thereby reducing the situation where the wearable component 2 and the heating pack 1 obstruct the bending of the toes, and thus reducing the discomfort caused by using the foot warmer.

[0066] Reference Figure 5 and Figure 6When the user's foot is placed inside the foot-wearing cavity 3, the wearing piece 2 is simultaneously fixed to the user's foot and ankle, so that the heating pack 1 is securely worn on the user's foot, thereby reducing the occurrence of the heating pack 1 falling off or shifting.

[0067] Specifically, in this embodiment, the wearable component 2 is fixed to the user's ankle through an ankle wearing hole 4 that passes through the wearable component 2. Figure 7 The ankle wearing hole 4 is crescent-shaped, and its geometric center is closer to the heel wearing part than the geometric center of the foot wearing part. The wall of the ankle wearing hole 4 has an outward protrusion 401, a concave portion 402, an enlarged portion 403, and a reduced portion 404. Both the outward protrusion 401 and the concave portion 402 are curved towards the front end of the wearer 2, with the curvature of the outward protrusion 401 being greater than that of the concave portion 402. When the user's ankle is worn through the ankle wearing hole 4, the outward protrusion 401 is closer to the toes and covers the instep than the concave portion 402, while the concave portion 402 is closer to the heel and covers the back of the heel than the outward protrusion 401. This allows the ankle wearing hole 4 to conform to the shape of the user's foot, making the wearer 2 more securely worn on the ankle.

[0068] Two shrinking portions 404 are provided, located on either side of the enlarged portion 403 along the width direction of the wearable member 2. The width d1 of the enlarged portion 403 is greater than the width d2 of the shrinking portion 404, and the enlarged portion 403 is further away from the edge of the wearable foot warmer than the shrinking portion 404. The width d1 of the enlarged portion is 10-20mm, and the width d2 of the shrinking portion is less than 10mm. When the user's foot needs to be accommodated in the foot wearing cavity 3, it passes through the foot wearing cavity 3 from the enlarged portion 403. The enlarged portion 403 makes it less likely for the ankle wearing hole 4 to obstruct the wearing of the foot and ankle, and the shrinking portion 404 makes the wearable member 2 more securely wrapped around the ankle.

[0069] The implementation principle of a wearable foot warmer in Embodiment 1 of this application is as follows: When wearing the foot warmer, align the sole of the foot with the ankle wearing hole 4 and insert it into the foot wearing cavity 3, so that the foot warmer is fixedly worn on the sole of the foot through the foot wearing cavity 3, and the ankle wearing hole 4 is fixedly worn on the ankle, thereby making it convenient for the user to cover the bottom of the sole of the foot to increase the body temperature of the foot.

[0070] Example 2:

[0071] Embodiment 2 of this application discloses a wearable foot warmer, which differs from the wearable foot warmer described in Embodiment 1 in that: (Refer to...) Figure 8 The heating powder is contained in a powder bag 5, which is located within the heating chamber 101. The powder bag 5 is made of a porous material, and the inner diameter of the pores in the powder bag 5 is smaller than the particle size of the heating powder. Furthermore, in this embodiment, the powder bag 5 is made of non-woven fabric.

[0072] The implementation principle of a wearable foot warmer in Embodiment 2 of this application is as follows: the powder bag 5 contains the heating powder, making it less likely for the heating powder to leak.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
