Abstract
The utility model relates to a vacuum inner container for the electric heating water kettle or the drinker, comprising an inner container whose upper end is provided with an opening and an outer wall. The upper opening of the inner container is outward provided with a fold edge corresponding to the fold edge outward arranged on the upper end of the outer wall. The lower end of the outer wall is also provided with a fold edge. The fold edge on the upper end of the outer wall is folded with the fold edge of the upper opening of the inner container and welded together. The fold edge on the lower end of the outer wall and the lower end of the inner container are folded and welded together to form a double-layer vacuum side wall. The combination and the welding of the outer wall and the inner container are combined by the upper and the lower fold edges of the outer wall and the fold edge of the upper opening and the surface of the inner container and thus the combination belongs to side-side type. The welding process is simple, the quality rate is high and the cost can be reduced. The structure of side-side combination has high stability and pneumatic sealing performance and the using effect of the utility model can be guaranteed.
Description
Technical field
The utility model is a kind of vacuum liner that is used for electric kettle or water dispenser, belongs to the improvement technology of existing vacuum liner.
Background technology
In electric kettle or water dispenser, its inner bag had both needed to play heating container, need heat insulation function again, in these products, inner bag adopts vacuum liner mostly, the single-layer metal plate is adopted as heating surface in the bottom surface of this class vacuum liner, and the side then adopts the double-level-metal plate to constitute the vacuum sidewall to reach the purpose of heat-insulation and heat-preservation.The formation of existing vacuum liner vacuum sidewall is fixing one deck outer wall outside a complete inner bag sidewall, and this outer wall upper edge and inner-tube mouth edge weld together, and outer wall lower edge and inner bag sidewall lower edge weld together, formation vacuum sidewall.This structure is because outer wall combines for the line face with the weld of inner bag, so welding process requirement is higher, influences the raising of product percent of pass, and structural stability and the bubble-tight degree of reliability are not high.
The utility model content
The purpose of this utility model provides that a kind of processing technology is simple, structural stability and the good vacuum liner that is used for electric kettle or water dispenser of air-tightness.
The technical scheme that realizes the utility model purpose is: the utility model is made up of the inner bag and the outer wall of upper end open, the upper shed of inner bag outwards has a flanging, corresponding, there is outside flanging the upper end of outer wall, the lower end of outer wall also is provided with flanging, the flanging of outer wall upper end is superimposed and weld together with the flanging of inner bag upper shed, and the flanging of outer wall lower end and inner bag lower end are superimposed and weld together formation double-layer vacuum sidewall.
In the technique scheme, the flanging of outer wall lower end is can be with the sidewall of inner bag lower end superimposed and weld together, and is also can be with the outer, bottom surface of inner bag lower end superimposed and weld together.
The beneficial effects of the utility model are: since outer wall and inner bag combine that to weld be the upper shed flanging of upper and lower flanging and inner bag by outer wall and inner bag is surperficial combines, therefore belong to the combination of face face, technology is simple during welding, the product percent of pass height, can reduce cost, the structural stability and the air-tightness of face face combination simultaneously are all very high, can guarantee result of use of the present utility model.
