Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1:

[0032] Please see Figure 1-2 A multifunctional shoulder bag in this embodiment includes a bag body 100, which is used to hold items;

[0033] Shoulder strap 200, which is detachably or fixedly connected to the bag body 100;

[0034] A plurality of heating elements 300 are disposed on the inner wall of the bag body 100 or in the interlayer of the bag body 100;

[0035] A storage battery 400 is located inside the bag 100;

[0036] PCB board 500 is disposed on one side of battery 400.

[0037] In this embodiment, the battery 400 and the heating element 300 are both electrically connected to the PCB board 500. The battery 400 is used to provide power to the heating element 300 and the PCB board 500. When the heating element 300 is working, it generates heat at a set temperature, so that the area above the heating element 300 forms a warm hand zone.

[0038] It should be noted that the heating element 300 is a graphene heating element. When the heating element 300 is working, it achieves rapid heating in 3 seconds based on the graphene pulse heating module. The heating element 300 adopts a graphene + carbon nanotube composite film structure to generate heat at the set temperature, so that the area above the heating element 300 forms a hand-warming area.

[0039] When the user needs the hand warming function, by pressing the button switch 302, the PCB board 500 receives the start signal and controls the graphene pulse heating module to turn on the power. The heating element 300 achieves rapid heating in 3 seconds based on the graphene + carbon nanotube composite film, generating heat at the set temperature. The heating element 300 uses dual temperature control chips to prevent overheating, and the dual temperature control chips are integrated into the PCB board 500.

[0040] When the user needs the hand warming function, the heating element 300 is activated by the button switch 302. After receiving the activation signal, the PCB board 500 transmits electrical energy to the heating element 300, and the heating element 300 starts to work, generating heat at the set temperature. This heat makes the area above the heating element 300 a hand warming zone, where the user can place their hands to warm them.

[0041] This multi-functional shoulder bag has a built-in heating element 300, powered by a rechargeable battery 400, which can provide a warming area for the user's hands in cold weather. This design solves the problem of traditional shoulder bags lacking active insulation, significantly improving the user experience, especially in winter or cold environments, providing users with extra comfort and convenience.

[0044] Please see Figure 2-5 In this embodiment, a temperature sensor 301 is provided on the inner side of the bag body 100 and near the heating element 300. A button switch 302 is provided on the surface of the bag body 100. The hand warming area includes a hand warmer bag 3001 provided on the bag body 100. Two hand openings 3002 are symmetrically provided on the hand warmer bag 3001. An invisible zipper 3003 is provided on the hand openings 3002. The heating element 300 is provided inside the hand warmer bag 3001.

[0045] Temperature sensor 301 is connected to PCB board 500 via signal, push button switch 302 is electrically connected to PCB board 500, and push button switch 302 is electrically connected to heating element 300.

[0046] It should be noted that the temperature sensor 301 monitors the temperature of the heating element 300 area in real time and feeds the data back to the PCB board 500. The PCB board 500 automatically adjusts the working state of the heating element 300 according to the set temperature threshold to achieve precise temperature control.

[0047] The user can manually start and stop the heating function by using the button switch 302 on the surface. The button signal is processed by the PCB board 500 to control the on and off of the heating element 300.

[0048] When hands need to be warmed, the user double-clicks the button switch 302 to activate the heating element 300. The signal from the button switch 302 is transmitted to the PCB board 500, which controls the battery 400 to supply power to the heating element 300. The heating element 300 then starts working and generates heat at the set temperature. The user then opens the hidden zipper 3003 inside the hand opening 3002 and places their hands into the hand warmer 3001 to warm them.

[0049] The PCB board 500 is provided with a charging input female connector 501, which is electrically connected to the PCB board 500 and is used to replenish the battery 400 with power.

[0050] The PCB board 500 also has a charging cable 502 of a certain length. The front end of the charging cable 502 has a charging male connector 503, which is used to charge mobile phones or other products.

[0051] The charging male connector 503 can be any one of the following: TYPE-C male connector, Apple male connector, or USB male connector.

[0052] The bag body 100 has an inner compartment 11, in which the charging cable 502 can be stored.

[0053] In application, when warmth is needed, the user activates the heating element 300 via the button switch 302. The signal from the button switch 302 is transmitted to the PCB board 500, which controls the battery 400 to supply power to the heating element 300. The heating element 300 then starts working, generating heat at a set temperature to form a hand-warming area. The temperature sensor 301 monitors the temperature of the heating element 300 area in real time and feeds the data back to the PCB board 500. The PCB board 500 automatically adjusts the working state of the heating element 300 according to the preset temperature threshold to ensure that the temperature is stable within a safe and comfortable range. Then, the user opens the invisible zipper 3003 inside the hand opening 3002 and puts their hands into the hand warmer bag 3001 to warm their hands. When it is necessary to charge a mobile phone or other devices, the user takes out the charging cable 502 from the interlayer 11 inside the bag body 100 and connects the mobile phone to the charging male connector 503. At this time, the battery 400 provides power to the mobile phone through the PCB board 500 to realize the charging function.
