Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating films, in particular to an anti-electric leakage heating film for building floors. Background Art
[0002] Existing electric heating floor tiles are usually strip-shaped, including a decorative layer for people to step on and a substrate located below the decorative layer. The substrate is usually made of wood or can also be made of other materials such as composite materials. Components such as heating films, connecting wires, plugs for connecting to an external power supply, etc. are provided on the substrate, as well as a tenon and groove structure for splicing the floor tiles pairwise. When the electric heating floor tiles are spliced into a floor, the heating film is heated by energizing the floor tiles, generating heat on the floor, so as to keep the indoor environment warm.
[0003] The existing heating film is usually a graphene electric heating film. The graphene electric heating film is a polyester film heating system that can generate heat energy after being energized, with a heat conversion rate as high as 99.28%, which is the highest among all current electric heating systems. The electric heating film technology was first applied to the aerospace industry.

However, since the electric heating film is a planar heating element with a relatively large surface area, a capacitive leakage current is formed between the large-area conductor and the ground. In addition, the graphene electric heating film itself is prone to generating electromagnetic waves due to the heating of electronic components, thus having an adverse impact on the human body.

[0031] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0032] Next, in combination with Figures 1 to 3 , a leakage - proof heating film for building floors according to an embodiment of the present utility model is described, which includes a heating film 10. A first protective layer 11 is provided on the upper surface of the heating film 10, and a second protective layer 12 is provided on the lower surface of the heating film 10; an upper conductive layer 21 is provided on the upper surface of the first protective layer 11, and a lower conductive layer 22 is provided on the lower surface of the second protective layer 12; the upper conductive layer 21 and the lower conductive layer 22 are electrically connected.
[0033] The settings of the first protective layer 11 and the second protective layer 12 enable the heating film 10 not to be in direct contact with the upper conductive layer 21 and the lower conductive layer 22, which plays a role in protecting the heating film 10 to a certain extent. In addition, the upper conductive layer 21 and the lower conductive layer 22 are electrically connected, so that there is no leakage current on the upper and lower surfaces of the heating film 10 during use, ensuring the safety of use of the anti-leakage heating film.
[0034] The utility model solves the problem of capacitive leakage current formed between a large-area conductor and the ground in the prior art through the electrically connected upper conductive layer 21 and lower conductive layer 22. At the same time, the settings of the upper conductive layer and the lower conductive layer can block the unsafe electromagnetic radiation generated by the heating film 10 when heated, further improving the safety of use of the anti-leakage heating film.
[0035] Specifically, the upper conductive layer 21 and the lower conductive layer 22 are electrically connected through a plurality of conductive terminals 50. At the same time, the plurality of conductive terminals 50 are arranged side by side on one side of the anti-leakage heating film, which can further block the unsafe electromagnetic radiation generated by the heating film when heated and improve the shielding effect of electromagnetic radiation.
[0036] Further, the conductive terminal 50 includes an insulating device 51 and a conductive sheet 52; the top and bottom of the insulating device 51 are both insulating clips 511, and two insulating clips 511 are provided with clamping openings; the two clamping openings are communicated through a guiding groove, and the conductive sheet 52 is installed in the guiding groove; the upper conductive layer 21 and the lower conductive layer 22 are respectively installed on the two clamping openings, and the upper conductive layer 21 and the lower conductive layer 22 are in contact with the conductive sheet 52.
[0037] Specifically, the upper conductive layer 21 extends into the insulating clip 511 at the top of the insulating device 51 and is in contact with the conductive sheet 52 in the guiding groove, and the lower conductive layer 22 extends into the insulating clip 511 at the bottom of the insulating device 51 and is in contact with the conductive sheet 52 in the guiding groove. The electrical connection between the upper conductive layer 21 and the lower conductive layer 22 is realized through the conductive sheet 52, so that there is no leakage current on the upper and lower surfaces of the heating film 10 during use, ensuring the safety of use of the anti-leakage heating film.
[0038] Furthermore, the positions where the conductive sheet 52 is in contact with the upper conductive layer 21 and the lower conductive layer 22 are both U-shaped conductive parts 521; one end of the conductive sheet 52 is in contact with the bottom of the guiding groove, and the other end of the conductive sheet 52 extends out of the insulating device 51 to connect to a power source. The setting of the U-shaped conductive part 521 makes the installation of the conductive sheet 52 on the guiding groove more stable, and at the same time increases the contact area between the upper conductive layer 21 or the lower conductive layer 22 and the conductive sheet 52, making the electrical connection between the lower conductive layer 22 and the upper conductive layer 21 more stable.
[0039] While blocking the unsafe electromagnetic radiation generated by the heating film 10 when heated, the upper conductive layer 21 will also attenuate the far-infrared beneficial to the human body generated by the heating film 10. Therefore, an anti-attenuation layer 30 is provided on the upper surface of the upper conductive layer 21 to offset the attenuation of the far-infrared beneficial to the human body caused by the upper conductive layer 21, thereby ensuring the usability of the anti-electric leakage heating film.
[0040] It should be noted that the anti-attenuation layer 30 is a carbon film, which can generate sufficient far-infrared beneficial to the human body when the heating film 10 generates heat, offsetting the far-infrared attenuation caused by adding the upper conductive layer 21 and improving the usability of the anti-electric leakage heating film.
[0041] Specifically, a third protective layer 40 is provided on both the upper surface of the anti-attenuation layer 30 and the lower surface of the lower conductive layer 22. The setting of the third protective layer 40 prevents the anti-electric leakage heating film from contacting the outside world, plays a role in protecting the anti-attenuation layer 30 and the lower conductive layer 22 to a certain extent, and extends the service life of the anti-electric leakage heating film 10.
[0042] More specifically, the first protective layer 11, the second protective layer 12, and the third protective layer 40 are all PET films. The PET film has the advantages of high transparency, non-toxic and odorless, ensuring the safety of the structure application of the heating film 10. In addition, the PET film has good viscosity, good conformability, and good weather resistance, and can withstand a high temperature of 150 degrees, enabling the first protective layer 11 and the second protective layer 12 to be firmly pasted onto the heating film 10, and at the same time, the heating film 10 will not damage the PET film when generating heat, ensuring the usability of the structure of the heating film 10.
[0043] Preferably, both the upper conductive layer 21 and the lower conductive layer 22 are aluminum films. The aluminum film is an aluminum oxide coating layer, which has strong stability and load-bearing capacity, so that when the anti-electric leakage heating film is applied to the floor, it has higher safety.
[0044] Preferably, the heating film 10 is a graphene electrothermal film. The graphene electrothermal film has the advantages of high efficiency and energy saving, good thermal stability, fast heating and uniform heat dissipation, which can meet the needs of users. In addition, the graphene electrothermal film has a long service life, reducing the maintenance cost, and at the same time, the manufacturing cost is also relatively low.
