Abstract

The utility model discloses a firm and durable thermos pot. An inner liner (5) and an outer liner (3) adopt stainless steel material, and the inner surface of the inner liner (5) is electroplated and prevents the thermal irradiation. The inner liner (5) and the outer liner (3) are separated at a connection opening through a thermal insulation ring (2) which is made of glass-reinforced plastic material, and the position between the inner liner (5) and the outer liner (3) is vacuated. The heat transfer from the inner liner (5) to the outer liner (3) is blocked, and the outer liner (3) with a pot handle is directly used as a pot skin. So the structure is simplified, the pot skin expenses is omitted, and the utility model with the same outer volume (compared with the common thermos pot) enlarges the water capacity of the inner liner (5).

Description

Thermos flask

The utility model relates to a kind of thermos flask.

Prior art be glass make inside and outside courage and common commercially available thermos flask that the kettle skin is arranged owing to adopt glass material to make inside and outside courage, inside and outside courage and bleeding point are very easily broken.

Task of the present utility model provides a kind of thermos flask, and it is sturdy and durable, unlikely fragmentation.

For solving above-mentioned task, the solution that the utility model adopts is: inside and outside courage and kettle bottom, kettle is all adopting stainless steel material to make, the inner bag inner surface is electroplated, and thermal radiation resistant is because metal is the good conductor of heat, its heat conducting approach can be by inner bag outside courage conduction at the Hu Kou place, so Hu Kou sentences heat-barrier material fiberglass and separates, and promptly separates with insulating collar, blocked hot conduction; Be evacuated between inside and outside courage, cutting off heat is that media outwards conducts with the air, and bottleneck covers the anti-thermal convection current of foam plugs.It is assembled into earlier outside that courage mouth place loads onto insulating collar, is inverted then, from the outer courage bonnet inner bag of packing into, covers outer courage bonnet then, bleeds and seals, and screws on the kettle bottom to protect bleeding point by the screw thread on the outer courage again.Reach outer courage bonnet interface between inside and outside courage and insulating collar, all increase contact area and frosted, make its contact quite tight, so that be evacuated, its outer courage bonnet interface is made the tubular structure of round platform, this kind thermos flask directly with by the outer courage that the kettle handle is arranged as the kettle skin, inner bag is heated and outwards expands behind the dress water, make contact between inner bag and insulating collar tightr.

Because above-mentioned solution adopts stainless steel as inside and outside courage, kettle is the material of, kettle bottom, thereby sturdy and durable, unlikely fragmentation, again since directly outer courage when the kettle skin, save kettle skin cost, simplify the structure, and identical outer volume, increase the inner bag water capacity.

Accompanying drawing is a longitudinal sectional drawing of the present utility model.

Claims (2)

1, a kind of thermos flask comprises inner bag (5), outer courage (3) and bleeding point (8), it is characterized in that inner bag (5) and outer courage (3) make with metal material; Directly kettle (4) by on the courage (3) outside: inner bag (5) and outer courage (3) separate with insulating collar (2) at bottle mouth position; Outer courage bottom is an outer courage bonnet (9), is provided with bleeding point (8) above.

2, thermos flask as claimed in claim 1, wherein inner bag (5) and outer courage (3) material therefor are stainless steel, insulating collar (2) adopts glass-reinforced plastic material.
