[0027] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0028] Please see Figure 1 and Figure 2 As shown, this application embodiment provides a heater, including a foot warmer component 1, a knee warmer component 2, a plastic connector 3, and a temperature control component 4. One end of the plastic connector 3 is connected to the foot warmer component 1, and the other end is connected to the knee warmer component 2. The plastic connector 3 itself is freely adjustable and can be suspended, causing the knee warmer component 2 to suspend accordingly. The temperature control component 4 is electrically connected to both the foot warmer component 1 and the knee warmer component 2. Functionally, the multifunctional foot warmer disclosed in this embodiment can warm both feet and knees, and the temperature of both the foot warmer component 1 and the knee warmer component 2 can be independently controlled by the temperature control component 4, allowing for flexible adjustment according to user needs and improving the user experience. Structurally, the knee warmer component 2 is supported by the freely adjustable plastic connector 3, allowing the user to freely adjust the position of the knee warmer component 2 and suspend it as needed, without the need for additional fixing devices, making it convenient to use.

[0029] The preferred knee warming component 2 and the plastic connector 3 are both provided in twos. Each knee warming component 2 is connected to the foot warming component 1 through a plastic connector 3, so that it can be used for the user's two knees respectively.

[0030] Of course, in other preferred embodiments, a single knee warmer 2 can be used to warm both of the user's knees at the same time. In this case, the knee warmer 2 needs to be made larger to provide warmth to both knees simultaneously.

[0031] See Figures 1 to 3In this embodiment, the foot warmer assembly 1 includes two heating elements: a foot warmer pedal 11 and a foot warmer cover 12, connected together by a rotating connection 13. The foot warmer pedal 11 and the foot warmer cover 12 rotate around the rotating connection 13, which is preferably a pivot, forming a shape similar to a laptop computer that can be freely opened, closed, and suspended. One end of the plastic connector 3 is connected to the foot warmer cover 12, so that the knee warmer assembly 2 moves together when the foot warmer cover 12 opens and closes, which facilitates both the use and storage of the knee warmer assembly 2. In use, the foot warmer pedal 11 and the foot warmer cover 12 are open and suspended, with the user's foot placed in the angle between them. The foot warmer pedal 11 heats the sole of the foot upwards, while the foot warmer cover 12 heats the instep downwards. This bidirectional, three-dimensional heating allows for a more even temperature distribution on the user's feet, resulting in a better foot warming experience. In storage, the foot warmer pedal 11 and the foot warmer cover 12 are folded, saving storage space. The pivot here is used to connect the foot warmer pedal 11 and the foot warmer cover 12, and to adjust and fix the space between the foot warmer pedal 11 and the foot warmer cover 12. It is understood that other movable connecting parts that also have the functions of adjustment and suspension can be used instead of the pivot, such as hinges, ratchet, etc.

[0032] The foot warmer pedal 11 and foot warmer cover 12 serve as the two heating elements of the foot warmer assembly 1. Their structure is as follows: each contains a heating element within a cavity enclosed by a housing. The housing of the foot warmer pedal 11 consists of a pedal base shell 111 and a pedal inner shell 112, while the housing of the foot warmer cover 12 consists of a cover outer shell 121 and a cover inner shell 122. Specifically, in the foot warmer pedal 11, a first heating element 101 is located within the cavity enclosed by the pedal base shell 111 and the pedal inner shell 112; in the foot warmer cover 12, a second heating element 102 is located within the cavity enclosed by the cover outer shell 121 and the cover inner shell 122. The housing serves two purposes: first, it provides protection, preventing the user's feet from directly contacting the heating element and causing burns; second, it utilizes the heat dissipation holes on the housing for convection heat exchange, preventing heat accumulation within the housing from damaging the foot warmer assembly 1, and also allowing this heat to be used for foot warming through convection heat exchange, reducing heat loss.

[0033] A reflector 113 is also provided between the foot warmer foot pedal 11's bottom shell 111 and the first heating element 101. This design has two advantages: first, it can reflect a portion of the heat radiation away from the user's foot back towards the user's foot, saving some heat and playing a role in environmental protection and energy saving; second, the reflector 113 can also block some of the heat radiation from the heating element to other parts of the foot warmer foot pedal 11, preventing the control board from being directly exposed to the heating element for a long time, which would accelerate aging and cause the control board to fail or be damaged.

[0034] See Figure 3In this embodiment, the plastic connector 3 preferably uses a gooseneck tube that can be adjusted and shaped in all directions. The gooseneck tube is used to adjust the knee warmer component 2 to a suitable position and allow it to automatically hover. This connection method has two advantages: First, from the user's perspective, the plastic connector 3 not only serves as a connector but also fixes the knee warmer component 2, eliminating the need for additional fixing devices during use, thus facilitating user operation. Second, from a design and manufacturing perspective, cleverly utilizing the two features of a single connector to achieve two functions reduces the number of parts, improves product integration, and simplifies the production process. It should be noted that the plastic connector 3 described in this application is not a limitation on the material of the connector itself; therefore, the material selection for the connector is not limited to plastic, brittle, or elastic materials. Specifically, the plastic connector 3 described in this application refers to the plasticity of the overall shape of the connector, meaning that the connector can freely adjust its shape, angle, and other overall shape features, and can automatically hover in any adjustable state. Therefore, the plastic connector 3 described in this application can also be made of other materials or mechanical structures that have both adjustment and shaping functions as the connecting part of the knee warmer assembly 2, such as: telescopic multi-section rods, multi-axis cantilever arms, or other structural combinations that can both adjust and shape. In this embodiment, the gooseneck tube is preferably used as the plastic connector 3. In addition to adjusting the position of the knee warmer assembly 2, it also functions as a wiring conduit. The wire 43 is run through the gooseneck tube to supply power to the knee warmer assembly 2. This design has two advantages: First, from the perspective of safety, laying the wire 43 in the gooseneck tube can provide an extra layer of protection for the wire 43, avoiding damage to the heater and reducing the probability of electric shock to the user; second, from the design perspective, the wire 43 is hidden in the gooseneck tube, eliminating the need for additional wire clips or winding to fix the wire 43, which simplifies the production process and avoids the wire 43 being exposed and causing a messy appearance.

[0035] See Figure 1 and Figure 4In this embodiment, there are two knee warming components 2. Their composition structure is as follows: the front shell 202 and the rear shell 201 of the knee warming component are combined to form a cavity, and a third heating element 204 and a reflector 203 are provided in the cavity. Specifically, the back and / or periphery of the rear shell 201 of the knee warmer component are provided with a first heat dissipation hole 2011, the periphery of the front shell 202 of the knee warmer component is also provided with a first heat dissipation hole 2011, and the front of the front shell 202 of the knee warmer component is provided with a second heat dissipation hole 2021. This arrangement serves three purposes: first, after the heater is stopped, the first heat dissipation hole 2011 facilitates the rapid dissipation of residual heat from inside the knee warmer component 2; second, it protects the user by preventing the user's knee from directly contacting the third heating element 204 during use; and third, it reduces the obstruction of heat radiation. The heat radiated towards the knee by the third heating element 204 and the heat reflected towards the knee by the reflector 203 are both blocked by the front shell 202 of the knee warmer component. The second heat dissipation hole 2021 on the front of the front shell 202 of the knee warmer component reduces this obstruction and improves the heating effect. In summary, the second heat dissipation hole 2021 is a design that balances user safety and heating effect.

[0036] See Figure 4 The reflector 203 in the knee warmer assembly 2 is located between the third heating element 204 and the rear shell 201 of the knee warmer assembly. The reflector 203 itself is a continuous concave curved surface. In this embodiment, it is preferably a parabolic conical surface. The parabolic surface can reflect the radial electromagnetic waves at the focal point into parallel propagation, which can make the reflected part of the thermal radiation energy more directional, reduce the heat loss caused by disordered propagation, and improve the energy consumption performance of the product.

[0037] This embodiment includes a foot warmer pedal 11, a foot warmer cover 12, and two knee warmer components 2, totaling four heating elements. Each of these four heating elements is independently controlled by a temperature control component 4, composed of a thermistor and a control board, allowing for independent adjustment of the temperature of any single heating element. This design offers two advantages: firstly, from a user experience perspective, the highly flexible control method better meets the diverse needs of different users; secondly, from an energy-saving and environmental protection perspective, precise local control can reduce overall energy loss and improve the product's energy efficiency.

[0038] See Figure 4 and Figure 5 In this embodiment, the connection between the plastic connector 3 and the heating element is fixed by a plastic pressure plate 51 and a fastening screw 52. The fastening screw 52 screws the plastic pressure plate 51 to the foot warming element 1 or the knee warming element 2. The end of the gooseneck tube is pressed and fixed to the foot warming element 1 or the knee warming element 2 by the plastic pressure plate 51. There are two advantages to using screw connection: First, it has high compatibility. No matter what material the plastic connector 3 of the heating element is made of, it can be screwed without adjusting the original design. Second, screw connection is convenient for disassembly and maintenance without damaging other original components.

[0039] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
