[specific embodiment]
In description, the size and shape of the heater of electric heater can not be particularly limited, and can need to adapt to adjustment according to design.
Casing in description, heated shell and housing seat all can be made integrative-structure by Shooting Technique by plastic material, manufacturing cost can decline greatly like this, can certainly adopt other material to make, as long as can reach the material that the various costs of designing requirement are low, all can consider.
Sealing ring in description and heated sealant circle all adopt silica gel or elastomeric material to make.
Described heat-generating disc can adopt the different heat modes that produce, and can be resistance wire heat-generating disc or infrared ray heating disc or light wave heat-generating disc.
Below in conjunction with accompanying drawing, by the specific embodiment of the present utility model is further described, make the technical solution of the utility model and beneficial effect thereof clearer, clear and definite.
Shown in accompanying drawing 1 to Fig. 3, the heater of a kind of electric heater that it provides for the utility model embodiment, this heater comprises water tank and heater, and heater is heat-generating disc 110, and described heat-generating disc 110 is positioned at water tank 120 bottoms.
Described water tank 120 comprises that inside has the casing 121 of cavity volume 123, with the housing seat 122 of described casing 121 Joints;
In described housing seat 122, be provided with heated shell 124, described heated shell 124 is combined to form heating chamber 128 with described heat-generating disc 110;
