However, the method of distinguishing the first pad 11 and the second pad 12 is not limited to this. In some embodiments, the first pad 11 and the second pad 12 can share a single sleeve. Within the same sleeve, the first pad 11 and the second pad 12 have different functional areas. The first pad 11 is used to house the heating element 2 for heating and heat preservation, while the second pad 12 is used to improve the heat preservation effect.

[0038] The structure of the pad 1 is not limited to a two-layer structure. Depending on the specific application scenario, in some implementations, the pad 1 can be a single-layer, three-layer, four-layer or more-layer structure.

[0039] In this embodiment, the locking structure 3 is a zipper, which includes: a first toothed rack, a first zipper head connected to the first toothed rack, and a second toothed rack. The first toothed rack and the second toothed rack are respectively placed at opposite ends or near the ends of the pad body 1, and the first toothed rack and the second toothed rack are engaged and connected through the first zipper head.

[0040] In some embodiments, the locking structure 3 is a hook and loop fastener, which includes a hook side and a loop side. The hook and loop sides of the hook and loop fastener are detachably connected by hooks and loops.

[0041] In some embodiments, the locking structure 3 is a magnetic attraction, wherein the locking structure 3 includes a first magnetic attraction and a second magnetic attraction. The magnetic attraction is detachable and connected through magnetic coupling.

[0042] In some embodiments, the locking structure 3 is a latch, which includes a female latch and a female latch. The female latch and the female latch are detachably connected by a physical locking mechanism.

[0043] In some embodiments, the locking structure 3 is a composite structure. Specifically, the locking structure 3 can be a composite structure of two or more connection methods selected from zippers, Velcro, magnetic closures, or buckles.

[0044] In this embodiment, the heating element 2 is a graphene heating element 2. However, the material of the heating element 2 is not limited. Depending on the specific application scenario, in some embodiments, the heating element 2 can be (but is not limited to): silicone heating element 2, metal heating film circuit, nickel-chromium alloy heating wire, and silicone rubber high-temperature insulating cloth or PET material.

[0045] In this embodiment, the heating element 2 is square or rectangular. However, the shape of the heating element 2 is not limited to this. Depending on the specific application scenario, in some embodiments, the shape of the heating element 2 can be (but is not limited to): circle, ellipse, pentagon or other polygon.

[0046] In this embodiment, the number of heating elements 2 is 1. However, the number of heating elements 2 is not limited to this. Depending on the specific application scenario, in some embodiments, the number of heating elements 2 can be 2, 3, 4 or more.

[0047] The heating element 2 is disposed inside the pad 1. However, the placement of the heating element 2 is not limited to this. Depending on the specific application scenario, in some embodiments, the heating element 2 can be disposed on the outer surface of the pad 1, or a notch can be made on the surface of the pad 1, and the heating element 2 can be disposed in the notch.

[0048] In this embodiment, one end of the electronic control module 4 is inserted into the pad 1, and the other end extends out of the pad 1. However, the connection method between the electronic control module 4 and the pad 1 is not limited to this. Depending on the specific application scenario, in some embodiments, the electronic control module 4 can be disposed on the surface of the pad 1.

[0049] In this embodiment, the electronic control module 4 is also connected to a power supply component, which can be a battery or a power bank. However, the structure of the power supply component is not limited to this. Depending on the specific application scenario, in some embodiments, the power supply component can be a socket that provides mains power.

[0050] In this embodiment, the decorative doll 5 is a stuffed doll. However, the structure of the decorative doll 5 is not limited to this. Depending on the specific application scenario, in some embodiments, the decorative doll 5 can be (but is not limited to): a silicone doll, a hard plastic doll, or a metal doll.

[0051] In the above embodiment, the main structure of the hand warmer is a foldable and bendable pad 1 that can be bent into a sleeve. The pad 1 is equipped with a locking structure 3 to maintain the sleeve shape. The pad 1 is equipped with a heating element 2 for heating and warmth and a corresponding electronic control module 4. A decorative doll 5 is placed on the side of the pad 1 facing away from the storage space. When the pad 1 is folded and bent into a sleeve, the decorative doll 5 can also be exposed. The decorative doll 5 has strong decorative value, enhancing the aesthetics and playability of the hand warmer. It also allows for customization to meet the individual needs of different users. Simultaneously, the decorative doll 5 increases the thickness of the hand warmer, improving its warmth retention. When the hand warmer is used in reverse, the user can hug the decorative doll 5 around their chest and abdomen, which, combined with the hand warmer's heating function, provides a good soothing effect.

[0052] In some embodiments, the decorative doll 5 is connected to the pad 1 via a first connection method 14, which is used to fix the decorative doll 5 to the pad 1.

[0053] The first connection method 14 includes a fixed connection method and a detachable connection method. The fixed connection method includes one of the following: sewn connection, adhesive connection, heat-pressed connection, etc. The detachable connection method includes one of the following: snap-on connection, zipper connection, magnetic connection, or Velcro connection.

[0054] When the first connection method 14 is a fixed connection, it can enhance the stability of the connection between the decorative doll 5 and the pad 1, making the connection of the decorative doll 5 more stable.

[0055] When the first connection method 14 is a detachable connection, the user can quickly separate the decorative doll 5 and the pad 1, making the hand warmer suitable for use in scenarios where the decorative doll 5 is needed or not, thus expanding the applicability of the hand warmer. Simultaneously, the detachable connection also allows the user to replace different types of decorative dolls 5 on the pad 1. For example, in one usage scenario, users and friends can exchange the decorative dolls 5 on their respective hand warmers. Another example is that users can replace the decorative dolls 5 representing different moods according to their own feelings, making the decorative dolls 5 an external, tangible representation of their mental state. Furthermore, the detachable connection method facilitates the disassembly and cleaning of the pad 1 and the decorative doll 5. For example, when the decorative doll 5 contains non-waterproof electronic components, disassembly and cleaning can protect the decorative doll 5 from damage.

[0056] In some embodiments, the decorative doll 5 is connected to the pad 1 via a second connection method 15, which is used to limit the activity space of the exposed part of the decorative doll 5.

[0057] The second connection method 15 is: storage bag 151. However, the second connection method 15 is not limited to this. Depending on the specific application scenario, in some implementations, the second connection method 15 can be: binding connection with straps.

[0058] The second connection method 15 limits the movement space of the exposed structure of the decorative doll 5. When an external force is applied to the decorative doll 5, the second connection method 15 can share the force applied to the first connection method 14, thereby increasing the firmness and stability of the connection of the decorative doll 5. At the same time, the second connection method 15 can restrain the partially exposed structure of the decorative doll 5, preventing the decorative doll 5 from swinging significantly under the action of external force, and reducing the problem of connection tearing caused by swing inertia.

[0059] In some embodiments, the area of ​​the connection between the decorative doll 5 and the pad 1 and the area of ​​the pad 1 are 0.15-0.25, so that the decorative doll 5 is prominently displayed on the sleeve surface.

[0060] The area at the connection between the decorative doll 5 and the pad 1 refers to the area of ​​the graphic formed by the connection path of the decorative doll 5 and the pad 1 using the first connection method 14. The area of ​​the pad 1 refers to the cross-sectional area of ​​the overall shape of the pad 1. When the values ​​of the area at the connection point of the pad 1 and the area of ​​the pad 1 are in the range of 0.15-0.25, when the pad 1 is folded and bent into a sleeve, the proportion of the decorative doll 5 on one side of the sleeve surface can reach 0.3-0.5. At this proportion, the decorative doll 5 is eye-catching and has a greater attraction to users.

[0061] In some embodiments, the second connection method 15 is: a storage bag 151, which is disposed on the side surface of the pad 1 facing away from the storage space, and at least part of the structure of the decorative doll 5 is placed inside the storage bag.

[0062] The storage bag 151 is connected to the pad 1 by sewing. However, the connection method of the storage bag 151 is not limited to this. Depending on the specific application scenario, in some embodiments, the connection method between the storage bag 151 and the pad 1 is (not limited to): adhesive bonding, heat pressing fusion, etc.

[0063] At least part of the structure of the decorative doll 5 is placed inside the storage bag. The storage bag 151 restrains the structure inside, preventing the decorative doll 5 from swinging excessively under external force and reducing the risk of tearing due to swinging inertia. At the same time, the combination of the structure of the storage bag 151 and the decorative doll 5 enhances the aesthetics and fun of the decorative doll 5, increasing user appeal.

[0064] In some embodiments, the storage bag 151 has a first through hole 151a, and part of the structure of the decorative doll 5 placed inside the storage bag 151 extends out of the storage bag 151 through the first through hole 151a.

[0065] The storage bag 151 has a first through hole 151a, which is a circular hole. A portion of the decorative doll 5 extends out of the storage bag 151 through the first through hole 151a. For example, when the decorative doll 5 is a human or animal doll, the lower half of the doll 5 is placed inside the storage bag 151, while one or both legs of the doll 5 extend out of the storage bag 151 through the first through hole 151a. Depending on the specific application scenario, any part of the decorative doll 5 can be placed inside the storage bag 151, and any part of the structure placed inside the storage bag 151 can also extend out of the storage bag 151 through the first through hole 151a. Therefore, it can be arbitrarily set according to the needs of the applicable environment, and is not limited to this example.

[0066] The storage bag 151 has a first through hole 151a, allowing a portion of the decorative doll 5 to extend out of the storage bag 151 through the first through hole 151a. The first through hole 151a restricts the extension of the structure from moving beyond the storage bag 151, limiting its movement to the area and range specified by the first through hole 151a. This structure further prevents the decorative doll 5 from swinging excessively under external forces, reducing the risk of tearing due to inertia. Simultaneously, the extension through the first through hole 151a enhances the aesthetics and appeal of the decorative doll 5, increasing its user appeal.

[0067] Please see Figure 3 , Figure 3 This is a front view of the second embodiment of this invention.

[0068] like Figure 3 As shown, in some embodiments, the storage bag 151 has a second through hole 151b, and the part of the decorative doll 5 placed inside the storage bag 151 extends out of the storage bag 151 through the second through hole 151b.

[0069] The storage bag 151 has a second through hole 151b, which is a circular hole. A portion of the decorative doll 5 extends out of the storage bag 151 through the second through hole 151b. For example, when the decorative doll 5 is a human or animal doll, the lower half of the doll 5 is placed inside the storage bag 151, while one or both legs of the doll 5 extend out of the storage bag 151 through the second through hole 151b. Depending on the specific application scenario, any part of the decorative doll 5 can be placed inside the storage bag 151, and any part of the structure placed inside the storage bag 151 can also extend out of the storage bag 151 through the second through hole 151b. Therefore, it can be arbitrarily configured according to the needs of the applicable environment, and is not limited to this example.

[0070] The storage bag 151 has a second through hole 151b, allowing a portion of the decorative doll 5 to extend out of the storage bag 151 through the second through hole 151b. The second through hole 151b restricts the movement of the extended portion, limiting it to the position and range of the second through hole 151b. This structure further prevents the decorative doll 5 from swinging excessively under external forces, reducing the risk of tearing due to inertia. Simultaneously, the extended portion through the second through hole 151b further enhances the aesthetics and appeal of the decorative doll 5, increasing user satisfaction.

[0071] In some embodiments, the storage bag 151 has a first through hole 151a and a second through hole 151b, and a portion of the decorative doll 5 extends out of the storage bag 151 through the first through hole 151a and the second through hole 151b, respectively. Compared to a single through hole structure, the double through hole structure can further enhance the binding ability of the extended portion of the decorative doll 5.

[0072] In some embodiments, the decorative doll 5 extends from the end of the portion of the structure of the first through hole 151a, and its cross-sectional area is larger than that of the first through hole 151a.

[0073] The end of the structure extending out of the first through hole 151a has a larger cross-sectional area than the first through hole 151a, which effectively prevents the extended part of the decorative doll 5 from retracting into the storage bag 151. Simultaneously, because the end of the structure extending out of the first through hole 151a has a larger cross-sectional area than the first through hole 151a, when the decorative doll 5 is subjected to external force and the extended part retracts, its end will contact the first through hole 151a, forming a reverse pulling force on the extended part. This restricts the extended part from retracting into the storage bag 151, increases the force-bearing area of ​​the storage bag 151, distributes the external force, and enhances the stability and connection firmness of the decorative doll 5.

[0074] In some embodiments, the decorative doll 5 extends from the end of the structure of the second through hole 151b, and its cross-sectional area is larger than that of the second through hole 151b.

[0075] The end of the structure extending out of the second through hole 151b has a larger cross-sectional area than the second through hole 151b, which effectively prevents the extended part of the decorative doll 5 from retracting into the storage bag 151. Simultaneously, because the end of the structure extending out of the second through hole 151b has a larger cross-sectional area than the second through hole 151b, when the decorative doll 5 is subjected to external force and the extended part retracts, its end will contact the second through hole 151b, forming a reverse pulling force on the extended part. This restricts the extended part from retracting into the storage bag 151, increases the force-bearing area of ​​the storage bag 151, distributes the external force, and enhances the stability and connection strength of the decorative doll 5.

[0076] In some embodiments, the pad 1 includes: a first pad 11 and a second pad 12, the second pad 12 being connected to one side surface of the first pad 11, a locking structure 3 being disposed on the first pad 11, a heating element 2 being disposed on or inside the first pad 11, an electronic control module 4 being disposed on the second pad 12, and a decorative doll 5 being connected to the first pad 11.

[0077] The pad 1 is divided into a first pad 11 and a second pad 12, which increases the thickness and insulation of the pad 1.

[0078] In some embodiments, the second pad 12 encloses the first pad 11 to form a blank space 13, and the decorative doll 5 is placed in the blank space 13 and connected to the first pad 11.

[0079] The design of the second pad 12 enclosing the blank space 13 enhances the artistic feel and visual appeal of the hand warmer, making the decorative doll 5 stand out more and attract consumers' attention. At the same time, the blank space 13 reduces the overall thickness of the pad 1, preventing the pad 1 from being too thick at the location of the decorative doll 5, which could easily lead to heat accumulation and create a safety hazard, thus improving the safety of the hand warmer.

[0080] In some embodiments, the second pad 12 includes a plurality of strip pads 121, which are arranged sequentially at intervals on one side surface of the first pad 11. Each strip pad 121 is connected to the first pad 11 at intervals, and there is a bending extension allowance between two adjacent connection positions in each strip pad 121.

[0081] The hand warmer's pad 1 is configured as a first pad 11 and a second pad 12. The second pad 12 is connected to the first pad 11 at intervals, and along the bending direction of the first pad 11, the second pad 12 has a bending extension allowance between two adjacent connection points. The connection method between the first pad 11 and the second pad 12, and the setting of the bending extension allowance of the second pad 12, allow the bending extension allowance of the second pad 12 to gradually expand when the hand warmer's pad 1 is bent. By transforming the bending process of the second pad 12 into a process of expanding the bending extension allowance, the bending stress of the second pad 12 during bending is greatly reduced. This results in a fluffy surface for the second pad 12, preventing excessive compression of the filling inside the pad 1, avoiding the phenomenon of wrinkles caused by pressure deformation inside the first pad 11, and improving the user experience. Meanwhile, the hand warmer contains a heating element. The heat from this element can accumulate inside the hand warmer, and if it cannot dissipate for a prolonged period, it can cause localized overheating and potentially ignite the hand warmer. The second pad 12 is spaced apart from the first pad 11, creating an insulation structure of varying thicknesses. The thinner areas are where the first and second pads connect or are sandwiched, providing good heat dissipation; the thicker areas are where the first and second pads overlap, providing good insulation. This design prevents heat buildup inside the hand warmer, achieving a good balance between insulation and heat dissipation, significantly improving the hand warmer's safety.

[0082] The strip-shaped pads 121 are arranged at intervals, with the space between adjacent strip-shaped pads 121 exposing the first pad 11. The exposed areas of the first pad 11 serve as effective heat dissipation channels, preventing excessive heat buildup inside the hand warmer. The overlapping areas of the strip-shaped pads 121 and the first pad 11 provide good insulation, further balancing the heat dissipation and insulation effects of the hand warmer and improving its safety. Simultaneously, when users use the hand warmer, their hand positions inside the hand warmer vary, resulting in different space requirements. The interval arrangement of the strip-shaped pads 121 prevents the internal stress from being transmitted to other strip-shaped pads 121 when subjected to varying hand expansion forces, thus avoiding the transfer of force from one area to another and causing discomfort to the user in other areas.

[0083] In some embodiments, the connection positions of two adjacent strip pads 121 to the first pad 11 are staggered.

[0084] The connection point between the strip-shaped pad 121 and the first pad 11 on the hand warmer is the most prone to bending, and the internal stress generated by bending at the connection point is minimal. The staggered connection points of adjacent strip-shaped pads 121 and the first pad 11 can evenly distribute the bending stress on the surface of the hand warmer pad 1, preventing situations where the pad 1 experiences excessively weak bending stress in some areas and excessively strong bending stress in others due to the absence of connection points, thus avoiding the phenomenon of difficulty in bending.

[0085] It should be noted that any of the embodiments in this example can be implemented independently or in combination with one or more other embodiments. When implementing in combination, the combination method should not be limited to the combination methods listed in this example.

[0086] It should be noted that while preferred embodiments of this application are provided in the specification and accompanying drawings, this application can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this application; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this application.
