Description

Structure of electrothermal film

The present invention provides a structure of an electric heating film, in particular, an electric heating film which is not easily broken by an internal heating element and which is easy to install.

According to the current temperature, it is more and more difficult to predict, and there are often very low or very high temperatures. For example, there are many places where snow does not snow in the winter, and even snow begins to come. Therefore, humans will use various items to protect themselves against such strong changes in temperature.

When winter comes, the most commonly used is the electric heater or electric heater, but in some areas it is not enough to use this product. Therefore, in some places, an electric blanket with an electric heating device or an electric heating film that can generate electricity directly under the floor can be used, thereby increasing the ambient temperature of the body or the whole.

Most of the electric heating films laid under the floor are made of carbonized cloth or some carbon fiber fabrics, which are used as conductive and heat-generating materials. However, the thermal expansion coefficient of the insulation layer attached to the upper and lower layers is extremely different. When the temperature changes too much, it is easy to break or break the heat-generating material due to the difference in thermal expansion coefficient, so that the product can no longer be used. As well as the conventional electric heating film, the surrounding area is sealed. When it is used, it is necessary to use a jig to poke into the inner conductive portion, and the installation method is also troublesome.

Therefore, how to solve the above problems and deficiencies in the past, that is, the applicants of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the creators of this new model have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed this type of carbonized cloth to be replaced by A new type of patented conductive plastic with a side that is not closed to increase the useful life and ease of installation of the electrothermal film.

The main purpose of the novel is to solve the problem of easy cracking because the conductive plastic has similar thermal expansion coefficients to the first insulating layer and the second insulating layer, and the side guiding members are not closed for convenient installation.

In order to achieve the above object, the main structure of the present invention comprises: a conductive plastic, a plurality of connecting members disposed on the conductive plastic, at least one first joint portion defined on the conductive plastic and located at the same side of the conductive member, at least a second bonding portion defined on the conductive plastic, and the second bonding portion is located at a side away from the first bonding portion, a first insulating layer bonded to the first bonding portion, and a second bonding portion The second insulating layer, wherein the conductive plastic comprises a plastic layer and a conductive layer disposed in the plastic layer, and when the first insulating layer is bonded to the first bonding portion, the guiding member is exposed outside the first insulating layer.

With the above structure, the user can directly connect the power supply source to the guiding member to pass the power source into the conductive plastic through the guiding member, thereby increasing the temperature of the conductive plastic to achieve the warming effect, the first insulating layer and The second insulating layer prevents leakage of the power supply and prevents the user from being exposed to electric shock. Since the guiding member is not enclosed in the first insulating layer, the power supply source can be directly connected to the guiding member during installation to improve the mounting efficiency, and the thermal expansion of the conductive plastic and the first insulating layer and the second insulating layer. The coefficients are similar, so even if the temperature changes too much, the conductive plastic will not be broken or broken, which will increase the service life.

According to the above technique, it is possible to achieve a breakthrough in the problem that the carbonized cloth is easily broken when the temperature changes excessively and is troublesome at the time of installation, and the practical advantage of the above advantages is achieved.
