Description

Heating film with protection mechanism

Technical Field

The utility model relates to the technical field of heating films, in particular to a heating film with a protection mechanism.

Background

The heating film is used as a novel low-temperature radiation electric heating element, is obviously different from the traditional electric heating body, and has the following characteristics of; the thickness is thin, the flexibility is good, the occupied space is small, the electric-thermal conversion efficiency is high, the radiant heat occupation ratio is large, the electromagnetic radiation is small, and the human body is not damaged;

most of the existing heating films directly wrap the outer surface of the heating sheet, so that colleagues who can generate high temperature to damage the outer surface of the heating film in the process of certain damage and short circuit of the heating sheet are easy to scald a user, and the heating sheets are often electrically connected with an external power line, so that when one heating sheet is damaged, other heating sheets are easy to use;

therefore, we propose a new heating film with a protection mechanism to solve the problems that the heating film is easily damaged by the damage of the heating sheet in the device and that other heating sheets cannot be used due to the damage of one heating sheet.

Disclosure of Invention

The utility model aims to provide a heating film with a protection mechanism, so as to solve the problems that the heating film is easily damaged by the damage of a heating sheet and other heating sheets cannot be used due to the damage of one heating sheet in the prior art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the heating film with the protection mechanism comprises a film main body, wherein rubber particles which are transversely arranged at equal intervals are embedded into the upper end and the lower end of the left side and the right side of the film main body, two fireproof layers which are arranged at equal intervals are embedded into the film main body, a power line is embedded into the right side between the two fireproof layers, and protective sleeves are embedded into the periphery of the outer side surface of the film main body;

clamping grooves which are transversely and equidistantly arranged are formed in the upper end and the lower end of the inner wall of the protective sleeve;

the left side fixedly connected with of power cord is the fuse of longitudinal equidistance range, the left side fixedly connected with heating plate of fuse.

Preferably, the rubber particles are arranged in a matching way with the clamping grooves, and the rubber particles are soluble glue.

Preferably, the cross section of the heating plate in plan view is wavy.

Preferably, the fireproof layer is made of glass fiber.

Compared with the prior art, the utility model has the beneficial effects that:

1. this kind of heating film with protection machanism is through being provided with the fuse, because each heating plate all is provided with the fuse alone for when arbitrary piece heating plate damaged, the fuse that corresponding damage heating plate set up can melt the outage, can not influence other heating plates when making the heating plate outage of damage, makes this heating film still can use.

2. Secondly, this kind of heating film with protection machanism is through being provided with the flame retardant coating, because the flame retardant coating is glass fiber material for the flame retardant coating insulativity is good, the heat resistance is strong and corrosion resistance and have stronger flame retardant property, make the heating plate damage short circuit all be difficult for the firing and produce high temperature and cause the damage to film main part surface, effectively improve life and security.

Detailed Description

Referring to fig. 1 to 2, in an embodiment of the present utility model;

example 1: the utility model provides a heating film with protection machanism, includes film main part 1, and the upper and lower both ends of the left and right sides of film main part 1 are all embedded to be provided with and are the rubber granule 102 that transversely equidistance was arranged, and the inside embedding of film main part 1 is provided with two-layer equidistant fire-proof layer 101, and the right side embedding is provided with power cord 3 between two fire-proof layer 101, and the outside face all nest all is provided with protective sheath 2 around film main part 1;

the protective sleeve is characterized in that clamping grooves 201 which are transversely and equidistantly arranged are formed in the upper end and the lower end of the inner wall of the protective sleeve 2;

the left side of the power line 3 is fixedly connected with fuses 301 which are longitudinally equidistantly arranged, and the left side of the fuses 301 is fixedly connected with a heating plate 302;

when any heating plate 302 is damaged, the fuse 301 corresponding to the damaged heating plate 302 will melt and power off, so that the normal operation of other heating plates 302 will not be affected while the damaged heating plate 302 is powered off.

Example 2: as can be seen by referring to fig. 2-3 of the specification, embodiment 2 differs from embodiment 1 in that:

the rubber particles 102 are matched with the clamping grooves 201, and the rubber particles 102 are soluble glue;

when the protective sleeve 2 is clamped around the outer side of the film main body 1, the rubber particles 102 deform after being extruded, meanwhile, after the protective sleeve 2 is clamped to the corresponding depth of the outer side of the film main body 1, the rubber particles 102 are clamped into the clamping groove 201, and when the protective sleeve 2 is heat-sealed with the peripheral area of the film main body 1, the rubber particles 102 are easy to fuse and seal with the clamping groove 201, so that the sealing performance of the protective sleeve 2 and the film main body 1 after heat sealing is effectively improved, and water is not easy to enter the film main body 1;

the top-down cross section of the heating plate 302 is wavy;

the wavy heating plate 302 can increase the heating area of the heating plate 302, so that the heating efficiency and uniformity are effectively improved;

the fireproof layer 101 is made of glass fiber;

the glass fiber fireproof layer 101 enables the film main body 1 to have good insulativity, strong heat resistance, corrosion resistance and strong fireproof performance, so that the high temperature generated in the moment of damaging the heating plate 302 and short-circuiting is not easy to damage the outer surface of the film main body 1 or scald a user, and the use safety is improved.
