Description
Technical field
The utility model belongs to a kind of drinking tool of personal daily life, that a kind of being easy to carry has the kettle of insulation effect, the structure that relates to vacuum structure between its internal layer of this kettle and skin, more specifically, propose a kind of suitable installation electrical heating elements, be convenient to the bottomless blank of double-layer vacuum, the kettle body that technique makes and the thermo jug that contains this kettle body.
Background technology
Stainless steel kettle adopts and form vacuum between inner bag and shell, for the maintenance of coolant-temperature gage, has important effect, and this class heat-insulation water bottle is subject to consumer's extensive welcome in the use.
Form vacuum between inner bag and shell, common way is, have steam vent at outer casing bottom, and be equipped with welding material on steam vent, allow housing take the method for vacuumizing when heating temperature raises, air between inner bag and shell is discharged from steam vent, simultaneously, by the welding material of melting, steam vent is sealed.
But, for the kettle body that the immersion electrical heating elements is set in kettle, bottom system does not have usually, it is made of inside and outside two-layer stainless steel, be the cylindrical structural of hollow, steam vent is to be formed at sidewall, is placed on and takes sleeping mode of putting in heating furnace, exist in put procedure, the problem of sliding easily appears in the kettle body, easily makes welding material displacement or landing, and sleeping putting also is not suitable for stacking, therefore, the structure of this kettle body and manufacture craft exist make efficiency and the lower problem of yield rate.
So, someone proposes to take the method that stretches, inwall at housing forms interior shoulder, to satisfy the setting of heating element heater, simultaneously, steam vent also is formed on interior shoulder, so that the kettle body can uprightly be placed in heating furnace,, interior shoulder must have certain-length and width for this reason, this makes again the metal stretching of internal layer easily occur breaking, and the yield rate of this structure and manufacture craft is still lower.
The problem of breaking easily appears for solving the excessive stretching of metal, someone proposes again to adopt the Welding Structure that is surrounded by inside and outside wallboard and back cover plate, connect inside and outside wallboard and form interior shoulder in inside by back cover plate, for the installation of electrical heating elements and the setting of steam vent.With reference to Fig. 5, inside panel 1 extends from top to bottom, and forms the neck section of a reducing in the bottom; Back cover plate 3 extends and bent horizontal transition and oppositely extension from bottom to top, forms the step of an opening; By inside panel 1, back cover plate 3 and exterior panel 2 welding, and neck section and step welding, the chamber that inside and outside wallboard etc. surrounds is sealed; Like this, steam vent a can easily be set on interior shoulder.
, this structure makes technique make needs to weld many places, namely except needs welding inside panel and exterior panel, back cover plate and exterior panel, also must the interface of neck section and step be welded, and has increased the number of times of welding operation.
Summary of the invention
The purpose of this utility model is the thermo jug that the bottomless blank of a kind of double-layer vacuum, kettle body will be provided and contain this kettle body, the bottomless blank of this double-layer vacuum provides a kind of structure, employing replaces traditional steam vent by the seam of building block, so that vacuumizing on the make, and in the seam welding, the isolated sealing of air is carried out in the gap.
The bottomless blank of double-layer vacuum of the present utility model, realized by following scheme:
The bottomless blank of a kind of double-layer vacuum, comprise inside panel, exterior panel and back cover plate, wherein, inside panel extends and forms in the bottom neck section of a reducing from top to bottom, and inside panel and exterior panel are in upper end sealing welding, and back cover plate and exterior panel are in lower end sealing welding, be characterized in, back cover plate is the annular surface with opening, and neck section can stretch in the opening of annular surface, and consists of by annular surface and neck section the annular crack that the cross section is inverted V-shape.
The bottomless blank of double-layer vacuum of the present utility model, also can be realized by following scheme:
