This application is capable of embodiments in many different forms than those described herein and that modifications may be made by one skilled in the art without departing from the spirit and scope of the application and it is therefore not intended to be limited to the specific embodiments disclosed below.

As shown in fig. 1, the heating device of the present application comprises a first portion 10 and a second portion 20 which are separated, such that in use, the first portion 10 is adjacent to the second portion 20 and covers part or all of the surface area of the second portion 20.

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.

As an example, the base material of the heating element 12 can be made of PET material, and a nickel-chromium alloy heating wire is wound on the base material, so that the product cost is low, and the mass production is facilitated. The user may also select other suitable heat generating component types. The shape of the heat generating component 12 may be adapted according to the outer shape of the first portion 10.

Preferably, the sending coil 22 and the induction coil 131 are arranged in parallel, which is beneficial to improving the connection stability of the sending coil 22 and the induction coil 131; further, the distance between the transmission coil 22 and the induction coil 131 is preferably less than 5cm, and the reception power of the induction coil 131 can be increased. When first portion 10 is proximate second portion 20 and covers a portion or all of the surface area of second portion 20, transmitting coil 22 and inductive coil 131 can establish a wireless connection to allow second portion 20 to wirelessly power first portion 10.

As an example, the power interface 25 is selected from a lightning interface, a MicroUSB interface, or a Type-C interface.

As an example, the second portion 20 further comprises a control 26 arranged on the outside, the control 26 being used to control a control circuit 27 between the sending coil 22 and the source of electric power. As an example, the control element 26 may control the on/off between the transmitting coil 22 and the source of the electric power, and may also adjust the transmitting power of the transmitting coil 22, for example, the control element 26 may be a multi-position switch, and the multi-position switch implements effective control on the transmitting power of the transmitting coil 22, so that a user may select an appropriate transmitting power according to needs to implement effective control on the heating temperature of the heating assembly 12. Specifically, the switch 26 may include three contacts, i.e., a neutral position (OFF) for disconnecting the transmitting coil 22 from the source of electric power, a low temperature position (L) for connecting the transmitting coil 22 to the source of electric power, and a high temperature position (H) for connecting the low temperature position and the high temperature position to resistors having different resistance values, respectively, to control the transmitting power of the transmitting coil 22. As an example, the control 26 may take the form of a toggle switch, a push button, or a knob.
