Description

Technical Field

[0001] This application relates to the field of heating pads, and more particularly to a heating pad for the hands and feet. Background Technology

[0002] Hand warmers are a common heating tool that works by using a galvanic cell to accelerate an oxidation reaction, converting chemical energy into heat energy. To prolong the duration of the heat, hand warmers typically contain vermiculite for insulation.

[0003] However, most heat patches currently on the market can only be applied to clothing, primarily to provide heat to the torso. This method of use is ineffective in addressing cold hands and feet. Furthermore, existing heat patches are not suitable for direct application to the hands or feet. Firstly, the adhesive surface of the heat patch is quite hot, and direct skin contact may cause burns. Secondly, the shape and material of the heat patch make it difficult to adhere completely to the hands or feet, reducing heat utilization, shortening usage time, and making it prone to falling off during hand movements, thus affecting the user experience.

[0027] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0030] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0031] like Figure 1 and 2 As shown, this application discloses a hand and foot warming patch, including a heating pack 1, one surface of the heating pack 1 is connected to a heat-insulating structure, and the other surface of the heating pack 1 is connected to a heat-insulating structure; a connecting strap 2 is connected to one side of the heating pack 1, and the other end of the connecting strap 2 can be connected to the opposite side of the heating pack 1, and the heating pack 1 and the connecting strap 2 form a ring.

[0032] This application incorporates an insulation structure on one side of the heating pack 1 to maintain its temperature, slowing down heat loss and extending its usage time. Furthermore, the insulation structure prevents direct skin contact with the heating pack 1, thus avoiding burns and improving safety. The combined use of the insulation and heat-resistant structures guides the flow of heat generated by the heating pack 1, ensuring a good heating effect and extended usage time. Finally, the heating pack 1 and connecting strap 2 allow the heating pad to be worn on the user's hands or feet, optimizing the user experience.

[0033] The heat insulation structure is connected to the side of the heating pack 1 closest to the user's hands or feet, while the heat preservation structure is connected to the side of the heating pack 1 furthest from the user's hands or feet. Therefore, most of the heat generated by the heating pack 1 flows toward the user's hands or feet, providing a better heating effect for the user.

[0034] In this embodiment, the heating pack 1 is square in shape. In other embodiments, the heating pack 1 may also be circular or other irregular in shape.

[0035] like Figure 3 As shown, in another embodiment, the connecting band 2 is elastic and is provided with at least one through hole 21 for accommodating a finger.

[0036] The elastic connecting band 2 can be adapted to hands or feet of different sizes within the elastic stretch range, improving the versatility of this application.

[0037] The through hole 21 allows the user's fingers to pass through, making it easier to put the heating patch on the hand; in this embodiment, there is one through hole 21, and the through hole 21 is used to accommodate the thumb; in other embodiments, there can be five through holes 21, so that all five fingers can pass through the through hole 21.

[0038] If you are putting the heating pad on your feet, you do not need to put your toes through the holes 21. You can put the heating pad directly on the instep or the sole of your foot.

[0039] like Figure 4 As shown, in another embodiment, the connecting band 2 is further provided with a wrapping portion 22 for wrapping around the finger at the through hole 21.

[0040] The wraparound part 22 can better fit the hand and prevent the edge of the through hole 21 from digging into the fingers, ensuring a better user experience.

[0041] like Figure 5 and 6 As shown, in another embodiment, the heat insulation structure includes a reflective layer 3 and a heat insulation layer 4, with the reflective layer 3 located between the heat insulation layer 4 and the heating pack 1.

[0042] The reflective layer 3 can reflect heat towards the heating pack 1, and the heat will pass through the heating pack 1 to the user, which can effectively reduce heat loss and bring a better heating experience to the user.

[0043] Most of the heat reaching the reflective layer 3 is reflected, and a small portion of the heat is transferred to the reflective layer 3 through heat transfer. Therefore, an insulation layer 4 is provided on the outside of the reflective layer 3. The insulation layer 4 slows down the heat conduction effect of the reflective layer 3, thereby reducing heat loss and extending the service life of the heating patch.

[0044] In this embodiment, the reflective layer 3 is aluminum foil. In other embodiments, the reflective layer 3 can also be a mirror reflective film, which is also called an aluminized reflective film. It is made of plastic films such as PET, BOPP, and CPP, which are formed by the natural adhesion of aluminum molecules under vacuum and high temperature conditions.

[0045] like Figure 6 As shown, the number of reflective layers 3 is at least two, and there is at least one gas space 31 between two adjacent reflective layers 3, which is filled with air.

[0046] By filling the gas space 31 with air, the heat conduction between adjacent reflective layers 3 is reduced, allowing more heat to be transferred through heat radiation, and more heat can be reflected back. Furthermore, since air has low thermal conductivity, it can also slow down the efficiency of heat conduction in the reflective layer 3, further reducing heat loss and extending the life of the heating patch.

[0047] like Figure 6 As shown, a release film 32 is attached to the side of the reflective layer 3 near the heating pack 1, and an adhesive layer 11 is provided on the surface of the heating pack 1 near the reflective layer 3.

[0048] Thanks to the adhesive layer 11, the heating patch can not only be used on the hands and feet, but also on clothes, thus expanding its application range.

[0049] The release film 32 reduces the difficulty for users to peel the insulation structure off the heating pack 1, making it easier for users to use.

[0050] like Figure 5 and 6As shown, the heat insulation structure includes a skin-friendly layer 5 and a heat insulation layer 6, with the heat insulation layer 6 located between the heating pack 1 and the skin-friendly layer 5; the heat insulation layer 6 has a number of staggered pores.

[0051] The heat insulation layer 6 prevents users from getting burned when using the heating pad; and the heat insulation layer 6 has several staggered pores, which allow the heat emitted by the heating pack 1 to fill the pores, so that users can feel the heat emitted by the heating pad more evenly and optimize the user experience.

[0052] like Figure 1 and 7 As shown, in another embodiment, the heating pack 1 has an adhesive portion 12 extending outward on both sides that are not connected to the connecting strip 2. The adhesive portion 12 has an adhesive layer 11 on the side facing the heat insulation structure. The adhesive portion 12 can be bent and bonded to the heat insulation structure. A release film 32 is attached to the heat insulation structure at the position corresponding to the adhesive portion 12.

[0053] The connection between the heating pack 1 and the insulation structure is reinforced by the adhesive part 12, which prevents the insulation structure from detaching during use when the user puts the heating patch on their hands or feet, resulting in serious heat loss and affecting the lifespan of the heating patch.

[0054] like Figure 1 As shown, there are several slits 14 arranged in a straight line at equal intervals at the connection between the connecting strip 2 and the heating pack 1.

[0055] By cutting slit 14, the connection between the connecting strip 2 and the heating pack 1 can be torn off along slit 14 when the user does not need the connecting strip 2, so that the heating patch can be used in more applicable scenarios.

[0056] like Figure 8 As shown, in another embodiment, the heating pack 1 is provided with a plurality of non-connected receiving cavities 13, and the receiving cavities 13 are filled with heating material.

[0057] The heating pack 1 has several cavities 13 filled with heating material. The heating pack 1 can be bent to ensure that the heating patch can better fit the user's hands or feet, reduce heat loss caused by the heating patch not fitting the hands or feet, ensure a better heating experience, and extend the applicable time of the heating patch.

[0058] The shape of the cavity can be one or more of the following: circular, rectangular, or polygonal.

[0059] Note that in the description of this specification, references to terms such as "an embodiment," "in other embodiments," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.
