[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1-5 , is an electric heating film heating device provided by the utility model, which includes an outer heating plate 1, fixed plates 15 are provided at both ends of the outer heating plate 1, and a fixed box 12 is provided on the outside of the fixed plate 15, and the length and width of the fixed plate 15 are the same as the internal length and depth of the fixed box 12, and a fixed plate 15 is symmetrically provided at the other end of the interior of the fixed box 12, and an outer heating plate 1 is also provided on the outside of the fixed box 12 at one end of the fixed plate 15; an inner heating plate 11 is provided between the outer heating plates 1, and a heat storage layer 14 is provided between the outer heating plate 1 and the inner heating plate 11, and fixed plates 15 are also provided at both ends of the outer heating plate 1, and a connecting block 16 is provided between the fixed plates 15, and an electrical connector 13 is provided on the outside of the fixed plate 15 on one side, and one end of the electrical connector 13 passes through the fixed plate 15 and is electrically connected to the outer heating plate 1 and the inner heating plate 11.

[0026] Specifically, fixed plates 15 are provided at both ends of the outer heating plate 1, and a fixed box 12 is provided on the outside of the fixed plate 15. The length and width of the fixed plate 15 are the same as the internal length and depth of the fixed box 12. A fixed plate 15 is symmetrically provided at the other end of the interior of the fixed box 12. One end of the fixed plate 15 is also provided with an outer heating plate 1 on the outside of the fixed box 12. Both ends of the outer heating plate 1 are fixed to the inside of the fixed box 12 by the fixed plates 15. The end surface of the outer heating plate 1 is flush with the end surface of the fixed plate 15. An inner heating plate 11 is provided between the outer heating plates 1, and a heat storage layer 14 is provided between the outer heating plate 1 and the inner heating plate 11. By using thermal insulation material, the heat between the outer heating plate 1 and the inner heating plate 11 is preserved through the heat storage layer 14; fixed plates 15 are also provided at both ends of the outer heating plate 1, and connecting blocks 16 are provided between the fixed plates 15. An electrical connector 13 is provided on the outer side of the fixed plate 15 on one side, and one end of the electrical connector 13 passes through the fixed plate 15 and is electrically connected to the outer heating plate 1 and the inner heating plate 11. The outer heating plate 1 and the inner heating plate 11 are connected through the connecting block 16, and the fixing box 12 is energized through the electrical connector 13, and then the outer heating plate 1 and the inner heating plate 11 are energized. The outer heating plate 1 and the inner heating plate 11 release heat after being energized.

[0027] The interior of the inner heating plate 11 is a hollow structure, and the interior of the outer heating plate 1 is evenly provided with multiple groups of heating layers 2 , and multiple connecting rods 21 are provided between the heating layers 2 .

[0028] Specifically, the heating layer 2 inside the external heating plate 1 releases heat inside the external heating plate 1 to increase the temperature of the external heating plate 1 , and the connecting rods 21 support the multiple heating layers 2 .

[0029] The heating layer 2 includes a plurality of heating units 3 , each of which is a regular hexagonal ring structure, and the plurality of heating units 3 are spliced in a honeycomb structure.

[0030] Specifically, the annular heating unit 3 increases the contact area between the heating layer 2 and the inside of the external heating plate 1, thereby improving the heating efficiency of the heating layer 2 inside the external heating plate 1. At the same time, after the heating layer 2 is powered off, the residual heat inside the external heating plate 1 continues to release heat outward for a period of time.

[0031] The connecting rod 21 is located at the joint of the heating units 3 , and the area of the connecting rod 21 is smaller than the area of the joint of the heating units 3 .

[0032] Specifically, the influence of the connecting rod 21 on the heating of the heating unit 3 is avoided, and the heat generated by the main body of the heating unit 3 is directly transferred to the outside.

[0033] A heat-conducting rod 22 is provided on the outside of the heating layer 2. The center of the heat-conducting rod 22 coincides with the center of the connecting rod 21. A heat dissipation block 23 is provided at the other end of the heat-conducting rod 22. The heat dissipation block 23 is truncated cone-shaped. The small round end of the heat dissipation block 23 is connected to the heat-conducting rod 22. The small round end of the heat dissipation block 23 fits with the heat-conducting rod 22. The large round end of the heat dissipation block 23 is connected to the inner wall of the inner heating plate 11. The size of the heat dissipation block 23 is also smaller than the area of the joint of the heating unit 3.

[0034] Specifically, the heat dissipation block 23 increases the area for directly transferring the heat of the heating unit 3 to the surface of the inner heating plate 11 , thereby improving the heating speed of the heating unit 3 to the outer heating plate 1 .

[0035] A heat-resisting block 24 may also be provided on the heat-conducting rod 22 at one end of the heating layer 2 , and the other end of the heat-resisting block 24 is in contact with the inner wall of the outer heating plate 1 .

[0036] Specifically, the heat-resisting block 24 can be used to change the external heating plate 1 to unidirectional heat release, so that the outer end of the external heating plate 1 is not heated.

[0037] The connecting rod 21 and the heat conducting rod 22 are made of materials with good heat dissipation effect; the heat dissipation block 23 is made of materials with good heat conductivity; and the heat resistance block 24 is made of materials with good heat resistance effect.

[0038] Specifically, the heat conduction is accelerated by the connecting rods 21 and the connecting rods 21 while avoiding the heat from being retained on the connecting rods 21 and the heat-conducting rods 22; the heating speed of the heating unit 3 to the external heating plate 1 is accelerated by the heat dissipation block 23; the heat on one side of the heating unit 3 is blocked by the heat-resisting block 24, thereby reducing the heat transfer to one side, so that the external heating plate 1 forms a one-way heating.

[0039] During use, the power connector 13 is energized to enable the outer heating plate 1 and the inner heating plate 11 to release heat, and the heat between the outer heating plate 1 and the inner heating plate 11 is retained by the heat storage layer 14. When the outer heating plate 1 and the inner heating plate 11 are not releasing heat, the heat storage layer 14 dissipates the heat; the outer heating plate 1 releases heat from the internal heating layer 2, and the heat of the heating layer 2 itself is directly transferred to the surface of the outer heating plate 1 and the inner heating plate 11 by the heat dissipation block 23, and the annular heating unit 3 on the heating layer 2 heats the interior of the outer heating plate 1 and the inner heating plate 11 as a whole, and transfers the heat to the surface of the outer heating plate 1 and the inner heating plate 11 more evenly; the heat can be blocked by the heat resistance block 24 at the outer end of the outer heating plate 1 to reduce the heat on the outer side of the outer heating plate 1, which can be adapted to scenarios with high unidirectional heating requirements.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
