Footwear temperature control device

The invention relates to a shoe, in particular to a shoe temperature control device arranged in the insole.

According to the development of human civilization, shoes have become one of the indispensable dresses for modern people when they go out. Whether it is a pair of shoes or sneakers worn in conjunction with outdoor activities, such as rain boots worn in rainy days, shoes are not only speechable as important to protect the human foot, but more importantly visible. Providing the corresponding functions on the demand, it is an important tool.

In the cold regions such as some cold belts, in addition to being warmer in the wear, the shoes are often provided with measures such as warming the feet when going out; for example, snow boots are easy to walk on the snow, and the interior is also like Materials such as fluff are used as a warming measure to suit the local climate and ambient temperature. However, such warming measures cannot determine whether or not to add to the needs of the wearer, especially when the temperature suddenly recovers, the foot is too warm to cause discomfort in wearing. Therefore, a heated insole that is added to the shoe as needed is also alive.

In the past, the heating insole is mainly converted into heat energy by using a heating coil circuit designed on the heating sheet after passing through a heating sheet in the battery to provide heat by contacting the film circuit with the human foot (foot). constant temperature. The existing heating insole is connected by a wire or directly by a heating piece in a connection manner between the battery and the heating piece. If the wire connection is used in the design, it is easy to cause the foreign body of the wearer's foot due to the relationship between the wire and the riveted joint of the wire, and it is not easy to make the insole thin and reach the waterproof requirement of the insole; Although the insole can be made thinner, after the long-term use of the heating sheet and the control box of the battery on the connected solder joint, the solder joint between the heating sheet and the control box is easily broken, which is always an important problem.

In particular, the general heating insole is to place the heating sheet and the control box in the insole. However, since the heating piece is straightened and flattened, when the wearer walks in the shoes, the insole is bent, so that the heating piece is also bent at the same time, and the bent heating piece is physically lengthed and leveled. Some are slightly different, so at least tensile stress and deformation force are generated when bending, and applied to the soldering spot of the control box of the heating sheet and the heating sheet, so that the above-mentioned problem such as breakage easily occurs.

In view of the above, the present inventors have made an effort to improve and solve the above-mentioned shortcomings, and have devoted themselves to research and cooperate with the application of the theory, and finally proposed a present invention which is reasonable in design and effective in improving the above-mentioned defects.

The main object of the present invention is to provide a shoe temperature control device which can solve the above problems and prevent the heating sheet and the control box from being easily broken or peeled off at the solder joint.

In order to achieve the above object, the present invention provides a shoe temperature control device, comprising a temperature control box, a heating sheet, and a pressing piece; wherein the temperature control box is provided with a connecting groove, and the temperature control box is in the connecting groove At least one side of the peripheral has a concave edge, and the heating piece has a heating portion and an extending portion extending from the heating portion, the connecting portion is provided with a connecting end, and the connecting end is fixed in the connecting groove, and the pressing piece is It is laminated with the concave edge and covers the connection end.

The detailed description of the present invention and the accompanying drawings are to be understood by the accompanying claims .
