Detailed description of the invention

Fig. 1 is the structural schematic diagram of the PTC line with heating function of the application in one embodiment.

Specific embodiment

The application is described in further detail below by specific embodiment combination attached drawing.

Below by specific embodiment combination attached drawing, invention is further described in detail.The application can be with a variety of Different forms is realized, however it is not limited to embodiment described in the present embodiment.The purpose of following specific embodiments is provided It is easy for becoming apparent from present disclosure thorough explanation, wherein the words of the indicating positions such as upper and lower, left and right is only needle To shown structure in respective figure for position.

However, those skilled in the art may be aware that one or more detail description can be by Omit, or can also adopt with other methods, component or material.In some instances, some embodiments are not described Or it is not described later in detail.

It is herein component institute serialization number itself, such as " first ", " second " etc., is only used for distinguishing described object, Without any sequence or art-recognized meanings.

In addition, technical characteristic described herein, technical solution can also be in one or more embodiments arbitrarily to close Suitable mode combines.For those skilled in the art, it should be readily appreciated that method related with embodiment provided herein Step or operation order can also change.Therefore, any sequence in drawings and examples is merely illustrative purposes, not secretly Show requirement in a certain order, is required unless expressly stated according to a certain sequence.

Embodiment one:
