Description of reference numerals: the hot melt adhesive comprises a heat insulation layer 1, an anti-pulling layer 2, a first glue layer 3, a metal heating body 4, a polyester film 5, a second glue layer 6, release paper 7, an outlet 8 and a bimetallic temperature control switch 9.

Detailed Description

The present invention will be described in further detail with reference to the drawings and the detailed description, but the present invention is not limited to the following examples.

Definition of terms:

the heat insulation layer 1 is mainly made of sponge, plays a role in heat insulation and can be made of PVC flame-retardant foaming sponge.

The stretch-proof layer 2 may be a PE stretch film which is actually a thermoplastic resin or cloth.

The material of the metal heating body 4 can be iron, chromium, copper, aluminum, or alloy thereof or other metal alloy.

The polyester film 5 may be a polyester film (PET). The polyester film 5 is provided with a metal heating body 4, and the polyester film and the metal heating body are integrally molded.

The release paper 6 is a release paper which can prevent the adhesion of the adhesive material and can also protect the adhesive material from being polluted. Can be kraft release paper or paper. It can be easily removed by hand.

Example one

As shown in fig. 1, the utility model provides a heating device includes insulating layer 1, prevents that draw layer 2, first glue layer 3, metal heating body 4, polyester film 5, second glue layer 6 and from type paper 7.

The heat insulating layer 1 may be formed on the surface in contact with the object to be heated, or the release paper may be formed on the surface in contact with the object to be heated. The anti-pulling layer 2 covers and is bonded on the heat insulation layer 1, and glue is coated on one side, far away from the heat insulation layer 1, of the anti-pulling layer 2 to form a glue layer 3.

Glue is applied to the heat insulation layer 1, and the polyester film 5 with the metal heating body 4 is attached to the heat insulation layer 1 for die cutting and forming.

After die cutting and forming, a second glue layer 6 is coated on the polyester film 5, and then the release paper 7 is covered, so that the heating device is completed.

Fig. 2 is a schematic top view of the heating device without release paper according to the first embodiment, in which the conductive wire is electrically connected to the bimetal temperature control switch 9, the bimetal temperature control switch 9 is electrically connected to the metal heating element 4, and the metal heating element 4 is electrically connected to another conductive wire. The bimetallic temperature-controlled switch 9 works, for example, in such a way that the circuit is on when the temperature is below 7 deg.c and off when the temperature is above 20 deg.c. The metal heating body 4 can be used as a heating resistor and an electrode.

Fig. 3 is a schematic bottom view of the heating apparatus according to the first embodiment, in which a wire outlet 8 is provided on the side of the heat insulating layer 1 not in contact with the metal heating body 4, and a lead wire is led out from the wire outlet 8.
