Abstract
The utility model provides a kind of overheated and line with heating function that is that seriously expand with heat and contract with cold of preventing, and comprises protective layer, exocuticle and heating wire; Described heating wire is wrapped in exocuticle; Described exocuticle is wrapped in protective layer; Described protective layer is fiber-like insulating material; Described protective layer appearance has one deck to cross the silicones glycerin layer of oil processing through silicones.Exocuticle material therefor is ceramic silicon rubber.Heating wire is carbon fiber exothermic wire.After adopting such structure, owing to installing layer protective layer additional, and this protective layer is fiber-like insulating material, so line with heating function expanded by heating can be prevented too large, improves useful life.
Description
Technical field
The utility model relates to a kind of line with heating function, especially a kind ofly prevents overheated and line with heating function that is that seriously expand with heat and contract with cold.
Background technology
Line with heating function has insulating case but the line that can conduct heat, that line inside the similar electric mattress of line with heating function for what heat, insulation, but heating after energising.Usually electric heating equipment is used in, as electric heater, roaster, far-infrared physiotherapy apparatus etc.
Current existing line with heating function outermost layer is all Plastic insulating material exocuticle, and line with heating function is heated and can expands, if too conference of expanding for a long time makes exocuticle aging ahead of time, has a strong impact on the physical life of line with heating function.
Utility model content
The utility model technical issues that need to address are to provide one and prevent line with heating function expanded by heating too large, and that improves useful life a kind ofly prevents overheated and line with heating function that is that seriously expand with heat and contract with cold.
Technical problem to be solved in the utility model realizes by the following technical solutions.
A kind ofly prevent overheated and line with heating function that is that seriously expand with heat and contract with cold comprises protective layer, exocuticle and heating wire; Described heating wire is wrapped in exocuticle; Described exocuticle is wrapped in protective layer; Described protective layer is fiber-like insulating material; Described protective layer appearance has one deck to cross the silicones glycerin layer of oil processing through silicones.
Described exocuticle material therefor is ceramic silicon rubber.Described heating wire is carbon fiber exothermic wire.
The invention has the beneficial effects as follows, owing to installing layer protective layer additional, and this protective layer is fiber-like insulating material, so line with heating function expanded by heating can be prevented too large, improves useful life.
Accompanying drawing explanation
To be that the utility model is a kind of prevent general structure schematic diagram that the is overheated and line with heating function seriously expanded with heat and contract with cold to Fig. 1.
In figure: 1. silicones glycerin layer; 2. protective layer; 3. exocuticle; 4. heating wire.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the utility model further.
A kind ofly prevent overheated and line with heating function that is that seriously expand with heat and contract with cold comprises protective layer 2, exocuticle 3 and heating wire 4; Described heating wire 4 is wrapped in exocuticle 3; Described exocuticle 3 is wrapped in protective layer 2; Described protective layer 2 is fiber-like insulating material; Described protective layer 2 appearance has one deck to cross the silicones glycerin layer 1 of oil processing through silicones.
Described exocuticle 3 material therefor is ceramic silicon rubber.Described heating wire 4 is carbon fiber exothermic wire.
More than show and describe general principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; without departing from the spirit and scope of the present invention; the utility model also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
