In this embodiment, the first part 10 has a heat generating component 12 and a receiving conversion component 13, wherein the heat generating component 12 and the receiving conversion component 13 are electrically connected. The receiving and converting assembly 13 comprises an induction coil 131 for taking electrical energy from the outside, wherein, in use, the induction coil 131 is located on the side proximate to the second portion 20 and the corresponding heat generating assembly 12 is located on the side opposite to the induction coil 131. Of course, in actual use, the relative positions of the heating element 12 and the induction coil 131 may be adjusted according to the shape of the heating device.
As an example, the receiving and converting assembly 13 further includes a receiving plate 132, the induction coil 131 is annularly wound on the receiving plate 132, and the inductive coil 131 is annularly disposed to effectively increase the coupling area of the wireless connection, thereby saving wires. As an example, the receiving plate 132 may be a flexible plate to allow the first portion 10 to be bent and folded to facilitate the conformable covering of the second portion 20.
As an example, the receiving and converting assembly 13 further includes an interference preventer (not shown in the figure) for preventing interference of external signals, which can effectively reduce interference of external interference sources to the receiving board 132, and improve stability and reliability of the induction coil 131 for receiving external wireless signals. In practical application, the anti-interference sheet can be pasted on the receiving plate 132, so that the operation is simple and convenient, and the practicability is high.
As an example, the first portion 10 may include a first cavity 11, and the heat generating component 12 and the receiving transforming component 13 are disposed in the first cavity 11 to prevent the heat generating component 12 and the receiving transforming component 13 from contacting the outside. As an example, the first part 10 may include an outer layer 101 and an inner layer 102, the first cavity 11 is surrounded by the inner layer 102, and the inner layer 102 is a waterproof layer, so that the first part 10 may be washed and dried in the air as a whole. As an example, the outer layer 101 may be a pile layer, which may be made of one or more materials selected from fur, acrylic, polyester, and polyvinyl chloride. As an example, the first cavity 11 may be semi-closed or fully closed.
