[0017] Example 1:

[0018] like Figure 1-4 As shown, the multifunctional hand warmer provided by this utility model includes: an outer shell 1, a bottom cover 14, and a heating structure;

[0019] An installation window is provided at the bottom of the outer casing 1; a bottom cover 14 is installed on the installation window; a cylindrical support liner 3 is provided inside the outer casing 1; a controller and a memory electrically connected to the controller are installed inside the support liner 3; two speakers 21 electrically connected to the controller are installed on the outer casing 1 via power amplifiers; four LED lights 18 are installed on the upper side of the outer casing 1, and the LED lights 18 are electrically connected to the controller via LED driver circuits; multiple control buttons 20 electrically connected to the controller are installed on the outer casing 1; each control button 20 includes a heating button, a light button, a play button, a volume up button, and a volume down button; a Bluetooth communication module electrically connected to the controller is installed inside the support liner 3; a heating structure is installed on the support liner 3 for heating and is controlled by the controller.

[0020] The heating structure heats the hands under the control of the controller, fulfilling the need for hand warming. The speaker 21 plays pre-stored audio files under the controller's control, and the LED 18 adjusts its brightness under the controller's control. A Bluetooth communication module facilitates connection with external devices, allowing them to play audio files through the speaker 21. Thus, the hand warmer fulfills multiple functions while providing hand warming. Various control buttons 20 facilitate sending signals to the controller: pressing the heating button starts the heating structure; pressing the play button controls the speaker 21; pressing the volume up or volume down button controls the speaker 21's volume; and pressing the light button controls the LED 18.

[0021] Furthermore, it also includes a mounting plate 13; the bottom of the supporting liner 3 is coaxially fixed to the upper inner wall of the outer shell 1, and the lower cylinder opening is opposite to the control window; multiple positioning seats 17 are provided in the middle of the inner circumferential surface of the supporting liner 3; the edge of the mounting plate 13 is installed on the lower side of each positioning seat 17 by bolts; the controller is installed on the upper side of the mounting plate 13; a battery powered by a power supply module is installed on the lower side of the mounting plate 13; a charging interface 19 electrically connected to the power supply module is installed on the outer shell 1; and a flexible pad 15 is installed on the upper side of the bottom cover 14.

[0022] The positioning seat 17 is used to fix the mounting plate 13 so that the controller is located inside the support lining 3, which can play a certain protective role; the flexible pad 15 plays a certain cushioning role.

[0023] Furthermore, the heating structure includes a heating wire 11, a heat-conducting ring 8, and a heat radiation protection ring 9; support rings 4 are provided on both the upper and lower sides of the outer circumferential surface of the supporting liner 3, supporting the inner circumferential surface of the outer shell 1; a heat insulation ring 5 is coaxially arranged between the two support rings 4; a heat insulation layer 12 is filled between the inner circumferential surface of the heat insulation ring 5, the outer circumferential surface of the supporting liner 3, and the opposite sides of the two support rings 4; the heat radiation protection ring 9 is coaxially mounted on the outer circumferential surface of the heat insulation ring 5; the outer circumferential surface of the heat radiation protection ring 9 is an arc-shaped ring with a concave center; the heating wire 11 is wound around the outer circumferential surface of the heat radiation protection ring 9. Furthermore, an electric control switch electrically connected to the controller is connected in series on the power supply line of the heating wire 11; a temperature sensor 10 electrically connected to the controller is installed on the heat radiation protection ring 9; a heat-conducting ring 8 is coaxially installed on the middle of the inner circumferential surface of the outer shell 1 and pressed on the heating wire 11; multiple heat-conducting holes 6 are arranged around the middle of the circumferential side wall of the outer shell 1; a heat-conducting layer 7 is provided on the outer circumferential surface of the outer shell 1, and heat-conducting protrusions are provided on the inner wall of the heat-conducting layer 7, which penetrate through each heat-conducting hole 6 and are pressed on the heat-conducting ring 8; each control button 20 is arranged horizontally at intervals on the circumferential side wall of the outer shell 1, and is located on the upper side of the heat-conducting layer 7.

[0024] The heating wire 11 is energized and generates heat under the control of the controller. The heat-conducting ring 8 presses on the heating wire 11, and the heat-conducting protrusions of the heat-conducting layer 7 press on the heat-conducting ring 8, so that the heat is transferred to the surface of the outer shell 1, thereby achieving the effect of warming the hands. The shape of the heat radiation protection ring 9 can provide a certain positioning effect for the heating wire 11. The heat insulation ring 5 uses existing heat radiation protection materials. The heat insulation ring 5 and the heat insulation layer 12 reduce the impact of the heating wire 11's heat generation on the components inside the supporting lining 3. The temperature threshold is set according to the requirements. The temperature sensor 10 monitors the temperature in real time. The controller controls the electric control switch to turn on or off according to the temperature data detected by the temperature sensor 10, so that the heating wire 11 is energized or de-energized. When the temperature is higher than the threshold, the heating wire 11 is de-energized. When the temperature is lower than the threshold, the heating wire 11 is energized, so that the hand warmer is at a suitable temperature for warming the hands.

[0025] Furthermore, a light-diffusing cover 2 is snap-on on the upper side of the outer shell 1; four LED lights 18 are all located inside the light-diffusing cover 2; and the light-diffusing cover 2 and the outer shell 1 form a flattened spherical structure. The LED lights 18 and the light-diffusing cover 2 are used for illumination. The light-diffusing cover 2 evenly distributes the light generated by the LED lights 18, optimizing the lighting effect. LED beads can be selected according to needs, so that the hand warmer can be used as a night light or ambient light; the flattened spherical structure formed by the light-diffusing cover 2 and the outer shell 1 makes the hand warmer structure rounded, improving the comfort of gripping.

[0026] In the multifunctional hand warmer provided by this utility model, the controller adopts an existing single-chip microcomputer control module; the LED light 18 adopts an existing LED light, and the LED driving circuit adopts a corresponding LED light driving circuit; the speaker 21 adopts an existing speaker, and the power amplifier adopts a corresponding speaker power amplifier; the heating wire 11 adopts an existing heating wire; the electric control switch adopts an existing electric control switch; the memory adopts an existing memory; the Bluetooth communication module adopts an existing Bluetooth communication module; and the temperature sensor 10 adopts an existing temperature sensor.

[0027] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
