As optimization, the upper end of the groove is provided with a mounting groove, and the wire penetrates into the groove from the mounting groove downwards. This optimization scheme wears to establish the wire from last down, conveniently walks the line and arranges, has reduced the possibility that the wire was touched, through setting up the mounting groove, provides the space for the welded contact that is qualified for the next round of competitions.

As optimization, the upper end of the mounting groove and the lead are arranged in a sealing mode. This optimization scheme is sealed the setting between mounting groove upper end and the wire, avoids water to flow into the recess from the top in, plays the fixed action to the wire simultaneously, prevents that wire and heating film from breaking off.

The utility model has the advantages that: 1. the sealing structure is used for installing the heating film in the corresponding groove, so that the separation of the water cavity and the heating film installation cavity is realized, and the safety of the heating film in the use process is improved; 2. the heat conducting and insulating products such as magnesium oxide powder, aluminum oxide powder and the like are uniformly filled around the heating film, so that the two sides of the heating film conduct heat uniformly, and the heating film is not easy to burn out; 3. the upper end of the sealing structure is provided with a mounting groove, and a space is reserved for an outgoing line welding contact.
