Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a heating device. Background Art

[0002] Heating insoles are commonly used daily necessities in winter, but the problems with heating insoles are that, on the one hand, the heating duration is short, and on the other hand, after the material inside the heating insoles is exhausted, it will expand and clump, resulting in uneven heating insoles, which greatly affects comfort.

[0003] In response to the current situation, many electric heating insoles have appeared. The existing electric heating insoles can only be adapted to one shoe size and have great limitations in use. Therefore, insoles of various sizes must be produced, which will greatly increase the production burden. In addition, the heating part and the insole are made into an integrated part, which is very inconvenient when brushing the insole. Special attention must be paid to the strength to avoid damaging the heating part in the insole, leaving safety hazards. Utility Model Content

[0008] The two heating plates and the bottom of the telescopic component are both provided with a fixing component, which is used to fix the heating plates and the telescopic component to the inner bottom of the shoe;

[0009] A battery and a controller are arranged in the shell. The controller has a high temperature protection function and can automatically cut off the power supply of the battery to the heating plate and the heating wire. The controller can make the heating plate and the heating wire run intermittently.

[0010] Using the above-mentioned heating device, one of the heating plates is fixed to the forefoot of the shoe through a fixing component, and then the telescopic component is pulled to make the other heating plate correspond to the rear sole of the shoe and fixed in the shoe.

[0021] The beneficial effects are:

[0022] 1. The two heating plates are fixed to the forefoot and the rear foot of the shoe through the fixing component. The telescopic component can follow the two heating plates to expand and contract, fill the gap between the two heating plates through the telescopic component, and transfer the temperature to the sole of the foot. In this way, it can adapt to shoes of different sizes and can heat the entire sole of the foot, thereby reducing the production process and improving production efficiency;

[0023] 2. The controller enables the heating plate to generate heat intermittently. After the temperature inside the shoe is raised by the heating plate, the residual heat inside the shoe and the body temperature of the human footsteps maintain the heat. After a period of time, the heating plate generates heat again. This reciprocating cycle can save power and prevent the shoe from overheating and making the user uncomfortable.
