Description

  The present invention relates to a shoe heat retaining structure, and in particular, is a structure that maintains the temperature inside the shoe by generating heat by friction using a rotatable bearing.

  Hands and feet are both important parts of the human body, and the feet also support weight, play a role in movement, such as maintaining balance and walking. It is important to choose comfortable and durable shoes to reduce the fatigue caused by the foot and the burden of supporting the weight for a long time by moving. For people who have poor circulation of peripheral blood vessels and those who tend to get cold, elderly people, those who prefer mountain climbing, and people who live in cold regions, shoes are comfortable and durable, and have a function of heat storage and heat retention. Improve the problem of poor blood circulation and maintain the temperature in the shoe. To achieve this goal, the inventor has invented the Chinese patent number M327181 “Insulation shoes”. The first coil is installed in the shoe and a heater is connected to it. The first coil senses the firing signal of the radio frequency launcher and generates power to provide the power required for the heater. A rechargeable battery is installed inside the shoe to store the generated power, so that even after the shoe is separated from the radio frequency launcher, it can provide enough power for the heater to operate, and the person wearing the shoe Providing a proper warming effect to the foot.

  Such a heat retaining shoe generates heat in the heater through electric power and brings a heat retaining effect to the shoe. However, structures that only function when combined with many components and complex circuits, such as coils, heaters, radio frequency launchers, and rechargeable batteries, are complex and the amount of charge stored in the rechargeable battery gradually decreases with the number of uses. As a result, the heating effect of the heater is weakened by the aging of the aircraft. Therefore, since the heat-retaining shoes consume a large amount of electricity in the heater, the heat-retaining effect is gradually deteriorated due to a shortage of batteries, and the same as ordinary shoes.

  In addition, since a sensing distance is provided between the coil and the radio frequency emitter, when a shoe is worn, if charging is required, activity within a certain range is forced. If you want to move freely, you must put on another shoe. When the amount of power storage is insufficient and the heating function is weakened, the number of times the warming shoes are charged will increase the charging time of each time. In view of the inconvenient use of the design, further improvements were necessary.
