Detailed ways

As shown in FIG. 1 , the utility model provides a portable intelligent temperature control warmer, which includes a USB interface 1 and a heating element 3 , and the USB interface 1 and the heating element 3 are connected through a wire 2 . The USB interface 1 can be directly connected to a computer, a power adapter, a mobile power supply, etc., and can provide a low-voltage DC power supply below 36V, so as to supply power to the heating element 3, so that the heating sheet 4 can be energized to convert electrical energy into heat energy, thereby achieving the effect of heating the outside. In this embodiment, there are two heating elements in the portable intelligent temperature control warmer, so that according to the characteristics of the human body, the left and right hands or the left and right ears can be heated at the same time, which is more convenient to use and more humanized. Preferably, the voltage of the low voltage direct current power supply is 5V.

In order to solve the defects of the heating device in the existing technical solution, the utility model mainly achieves a new technical effect by setting the heating sheet 4 in the heating body 3, so that people can use the electric warming treasure products more conveniently. Comfort and safety. The manufacturing steps of the heating sheet are as follows: according to the impedance of the alloy wires, a plurality of alloy wires are plied to form a heating wire with a predetermined impedance. When a voltage is applied to both ends of the heating wire, the heating wire consumes electric energy to heat up; The step of setting the heating thread on the lining: After coiling the heating thread, it is sewn onto the lining 41 on one side, and then covered with another lining, and then sewed again, so as to make the lining 41. 41-surface alloy heating sheet. What this embodiment provides is the best way of coiling the heating wire on the lining, that is: spiral coiling. In addition, the heating wire can also be coiled in a rectangular or other suitable shape, as long as the heating wire does not Just do a crossover.

In order to control the temperature of the heating body in the process of research and development of the utility model, a temperature control switch connected in series with the heating sheet is set on each heating body, and the on and off of the circuit can be controlled through the internal setting of the temperature control switch, so that the heating Bao provides the most suitable heat for the outside world. When the temperature provided by the warm treasure reaches the set maximum temperature, the temperature control switch will automatically cut off the power supply, so that the heating element will stop working, but the other heating element connected in parallel with this heating element will generate heat normally, and will not be affected by each other. , so as to achieve that according to the environment where the two heating elements are located, they can work independently and generate heat intelligently; when the temperature of the heating element drops below the set minimum temperature, the temperature control switch in the temperature control switch will automatically close to make the heating The tablet starts to heat up. Preferably, the temperature adjusted by the thermostat is between 25°C and 50°C.

In order to enable the temperature control switch to accurately measure the temperature of the heating sheet, the temperature control switch and the heating sheet are closely arranged, that is, the temperature control switch is set on the lining, so that the temperature control switch and the heating wire are separated by only one layer of lining, and There is no gap in the middle, so that the effect of accurate temperature control can be achieved.

The heating element 3 also includes a protective cover. The shape of the protective cover can be set as the most convenient circular shape, or it can be made into different shapes according to people's preferences, so that people can use it more conveniently and touch it more comfortably. In addition, the protective cover has two layers of inner and outer layers, the inner layer is made of wool-faced textile material, has a pocket-shaped cavity, and a zipper or sealing strip for sealing the pocket is set at the opening where the cavity communicates with the outside world , you can place some pocket money, keys and other small daily necessities in the cavity. Moreover, the setting of the inner cavity can also put your hands into the cavity to warm without putting anything, that is, when using the warm treasure to warm the face, ears and other parts except the hands, you can put both hands at the same time Protect it from frostbite; the outer layer is made of flexible textile material, and some embroidery can be designed on the outer surface to make the product more beautiful; there is an insulating layer made of sponge and other insulating materials between the outer layer and the inner layer , the heating sheet 4 is arranged between the thermal insulation layer and the outer layer, and the heating sheet 4 can be arranged on one side where the inner layer forms the cavity, or on both sides of the cavity.

In people's daily life, facing the heating products that people carry with them, cleaning is a very difficult problem, because electronic products are easy to conduct electricity after cleaning, causing potential safety hazards. In order to solve this technical problem, the utility model uses an alloy wire heating sheet, which can be directly cleaned and dried. Since the alloy wire is made of copper-nickel alloy or nickel-chromium alloy, the service life will not be shortened due to rust after cleaning, and the It will cause potential safety hazards and is more suitable for various groups of people to use in various environments. Preferably, the protective cover of the present utility model can also be set to be detachable, that is, the inner layer and the outer layer of the protective cover are connected by a zipper or a sealing line, and people can replace protective covers of different designs according to their own preferences. It can also be disassembled and cleaned to make the use of warm treasure more humanized.

Preferably, an ear support can be provided on one side of the protective cover, which can be directly placed on the ear to keep warm, and an accessory structure can also be added to the protective cover to adapt to the application of people in various situations.

The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
