Description
Technical field
The utility model relates to silicon rubber heating sheet technical fields, particularly belong to a kind of silicon rubber heating sheet.
Background technique
Heating sheet is a kind of laminar electric appliance for reaching heating effect using electric energy, it have it is small in size, easy to use and
The high advantage of heating efficiency, and heating temperature can be controlled, had a wide range of application by intelligent temperature control system, the service life
It is long.Existing heating sheet heats target object since top and bottom can transmit temperature simultaneously, and when heating sheet only has one side
When contacting with target object, heating sheet another side will be unable to play heat effect, will lead to heat and wastes.And it is most
Mainly there was only a resistive heater inside heating sheet, when open circuit occurs in the resistance wire in heater, whole heating sheet will be reported
It is useless, and the non-uniform temperature of the heating surface of heating sheet, heating effect are poor.
Utility model content
The purpose of the utility model is to provide a kind of silicon rubber heating sheets, overcome the deficiencies in the prior art.
To solve the above problems, technical solution adopted in the utility model is as follows: a kind of silicon rubber heating sheet, including just
Pole wiring hole, negative terminal hole, conducting wire, resistance wire, silicon rubber, heat conducting film and insulation sheet, it is the conducting wire, resistance wire, thermally conductive
Film and insulation sheet are all located in the matrix of silicon rubber, and the resistance wire both ends pass through conducting wire and positive terminal hole and cathode respectively
Wiring hole is connected, and the both ends of the silicon rubber are both provided with positive terminal hole and negative terminal hole, the positive terminal hole
It is connected between positive terminal hole by conducting wire, is connected between the negative terminal hole and negative terminal hole also by conducting wire,
The heat conducting film is located at the top of resistance wire, and the insulation sheet is located at the lower section of resistance wire.
Further, in parallel between the resistance wire.
Further, the heat conducting film is flexible heat conducting film, and the area of the heat conducting film is greater than face shared by resistance wire
Product.
Further, the insulation sheet is flexible heat-insulating piece, and the area of the insulation sheet is greater than the area of heat conducting film.
Compared with prior art, the implementation result of the utility model is as follows: in the silicon rubber heating sheet
Resistance wire between it is in parallel, when avoiding a wherein resistance wire open circuit caused by whole heating sheet lose asking for heating efficiency
Topic；In the lower section of resistance wire, one flexible heat-insulating plate is set, the heat for avoiding resistance wire generation is lost downwards, and on resistance wire
The heat conducting film being just arranged, the upper surface for being distributed in silicon rubber for the even heat that resistance wire can be generated, and ought have resistance wire
Occur open circuit when, heat conducting film can also the more uniform distribution on the upper surface of silicon rubber by heat, without generate silicon rubber add
The backing upper surface larger phenomenon of temperature difference everywhere；By being designed with wiring hole at the both ends of silicon rubber heating sheet, it can be achieved that
Multiple silicon rubber heating sheets are used in series, and silicon rubber heating chip architecture is simple, surface temperature is uniform, easy to use.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the internal resistance silk of the utility model.
Fig. 3 is the main sectional view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-3, a kind of silicon rubber heating sheet described in the utility model, including silicon rubber 1, positive terminal hole 2,
Negative terminal hole 3, conducting wire 4, resistance wire 5, heat conducting film 6 and insulation sheet 7, conducting wire 4, resistance wire 5, heat conducting film 6 and all positions of insulation sheet 7
In in the matrix of silicon rubber 1,5 both ends of resistance wire pass through conducting wire 4 respectively and are connected with positive terminal hole 2 and negative terminal hole 3, each electricity
Parallel connection between silk 5 is hindered, the both ends of silicon rubber 1 are both provided with positive terminal hole 2 and negative terminal hole 3, positive terminal hole 2 and anode
It is connected, is connected between negative terminal hole 3 and negative terminal hole 3 also by conducting wire 4, heat conducting film 6 by conducting wire between wiring hole 2
In the top of resistance wire 5, heat conducting film 6 is flexible heat conducting film, and the area of heat conducting film 6 is greater than area shared by resistance wire 5, insulation sheet
7 are located at the lower section of resistance wire 5, and insulation sheet 7 is flexible heat-insulating piece, and the area of insulation sheet 7 is greater than the area of heat conducting film 6.
It is in parallel between resistance wire 5 in the silicon rubber 1, whole caused by avoiding when wherein a resistance wire 5 is breaking
Heating sheet loses the problem of heating efficiency；One flexible heat-insulating plate 7 is set in the lower section of resistance wire 5, avoids the generation of resistance wire 5
Heat is lost downwards, and the heat conducting film 6 being arranged above resistance wire 5, being distributed in the even heat that resistance wire 5 generates
The upper surface of silicon rubber 1, and when there is resistance wire 5 that open circuit occurs, heat conducting film 6 can also be by heat on the upper surface of silicon rubber 1
More uniform distribution, without generating 1 upper surface of the silicon rubber larger phenomenon of temperature difference everywhere；By in silicon rubber heating sheet
Both ends be designed with wiring hole, it can be achieved that multiple silicon rubber heating sheets are used in series.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
