Fruit, it is capable of the heat transfer of effectively retarding heat；Heat-reflecting layer 191, typically has metal material to be made, and has the antiradiation of metal
Characteristic, the heat radiation of inner bag 12 can be reflected back inner bag 12, avoid mode of the heat of inner bag 12 Jing Guo heat radiation to
The direction of one end cap 13 is lost in.
In order that thermal insulation layer 19 can give full play to heat-blocking action, plate of the above-mentioned vacuum insulation panel 192 towards stifled bubble part 15
Face is bonded with the surface of stifled bubble part 15 towards inner bag 12, and now the contact area of vacuum insulation panel 192 and stifled bubble part 15 is maximum, this
When vacuum insulation panel 192 can prevent heat from inner bag 12 to stifled bubble part 15 to greatest extent on carry out heat transfer, and then avoid
Heat is outwards lost at the first end cap 13 so that the heat-insulating property of electric heater 10 further gets a promotion.
In certain embodiments, above-mentioned heat-reflecting layer 191 is arranged on plate face of the vacuum insulation panel 192 backwards to stifled bubble part 15
On.Further, above-mentioned heat-reflecting layer 191 is realized with various ways, for example, heat-reflecting layer 191 can be metal foil film, preferably
Ground tinfoil paper or aluminium foil are to reduce production cost；Heat-reflecting layer 191 can also be the coating formed by nano-metal particle, pass through
Mounted box will be sprayed by the surface of nano-metal particle spraying and vacuum insulation panel 192 and/or stifled bubble part 15 to form heat-reflecting layer
191。
In the present embodiment, ring flange 18 is connected with above-mentioned courage mouth 121, the end for heating pipeline is solid by ring flange 18
Be scheduled on courage mouth 121, on stifled bubble part 15 to should ring flange 18 offer through hole 151, above-mentioned ring flange 18 is arranged on the through hole
In 151.It should be noted that by setting stifled bubble part 15, can be by the position of inner bag 12 in foaming thermal-insulating foaming process
Put and be positioned in housing 11, avoiding the pressure of foaming thermal-insulating makes inner bag 12 out of position, by that will be connected to courage mouth
121 ring flange 18 is arranged in the through hole 151 of stifled bubble part 15 so that positioning relation is formed between inner bag 12 and stifled bubble part 15,
Inner bag 12 is avoided to shift.By setting through hole 151, the wire for the end that also can also conveniently heat pipeline passes through through hole
151, it is connected with the circuit board being arranged on outside stifled bubble part 15.
It should be noted that stifled bubble part 15 corresponds to through hole 151 close to the surface of courage mouth 121 and is provided with annular flange 152, annular
The inner surface of flange 152 is bonded with the outer surface of ring flange 18.By setting annular flange 152, can increase stifled bubble part 15 with
The contact area of ring flange 18 so that form relatively reliable positioning between inner bag 12 and stifled bubble part 15.
In order to further avoid heat from being transmitted from inner bag 12 to the direction of the first end cap 13, above-mentioned stifled bubble part 15 and inner bag 12 it
Between be additionally provided with heat-preservation cotton plate, heat-preservation cotton plate corresponds to above-mentioned annular flange 152 and is additionally provided with installation gap, with cause heat-preservation cotton plate with
Stifled bubble part 15 better contacts with, and increases both contacts area, to strengthen its heat insulating effect.
In the present embodiment, above-mentioned stifled bubble part 15 sets fluted 153 towards the side of the first end cap 13, and the groove 153 is used
In the circuit board for placing heating pipeline, while the groove 153 is connected with through hole 151 in order to heat the wire of pipeline and circuit board
Connection.For the ease of heating pipeline is repaired and changed, the operation aperture of corresponding first end cap 13 of notch of the groove 153
132 are set, and can be sealed off upper groove 153 with extraneous by installing lid 14, to prevent extraneous steam from entering the groove
153。
Reference picture 4 and Fig. 5, in order to prevent in foaming process, gap of the foamed material along stifled bubble part 15 and the first end cap 13 is oozed
Leakage, thus should be tightly connected between the stifled bubble end cap 13 of part 15 and first, prevent foamed material seepage.Based on above-mentioned purpose, bubble is blocked up
Part 15 offers closure gasket groove 155 back to the side of courage mouth 121, and the corresponding closure gasket groove 155 of the first end cap 13 offers sealing flange
131, sealing flange 131 is bonded towards the surface of closure gasket groove 155 with the trough wall surface of closure gasket groove 155.Pass through sealing flange 131
Face face between closure gasket groove 155 is bonded, and then can effectively prevent the seepage of foamed material.
Further, in order that electric heater 10 can fill more expanded materials, block up between bubble part 15 and housing 11 also
Gap is left, stifled bubble part 15, the end cap 13 of housing 11 and first are enclosed to form accommodating cavity 20, and hair can be filled in the accommodating cavity 20
Foam material, and then increase the volume of insulating foam layer, further lift the heat-insulating property of electric heater 10.
To expand the volume of above-mentioned accommodating cavity 20, further to fill more expanded materials, bubble part 15 is blocked up towards housing 11
Surface be provided with accommodating hole, the accommodating hole connects with accommodating cavity 20.Preferably, block up on bubble part 15 and be provided with multiple accommodating holes, should
Outer rim side face of the accommodating hole along stifled bubble part 15 is uniformly distributed so that the expanded material of stifled bubble part 15 surrounding filling is more uniform.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
