Abstract

The utility model relates to a double layer vacuum stainless steel thermal insulation pot, which comprises a stainless steel pot body with a vacuum interlayer and a plastic pot ring (1), which is buckled with the pot body. The pot body is composed of a stainless steel outer bag (2) and an inner bag (3), which are welded together and vacuumized. The welding neck of the outer bag (2) and the inner bag (3) on the pot body is flexed inwards to make a welding steam (5) facing inward. A downward flute of the pot ring (1) is provided with a convex loop (7), which can be clipped into a concave ring at the neck of the pot body. For the welding neck of the outer bag and the inner bag is flexed inward, the inner bag can be basically made into a cone platform, so that the water in the pot can be conveniently emptied. For a clipping ring is formed by the concave ring at the neck of the pot body at the same time to clip the pot ring, the material is saved and the cost is reduced. The bottom of the pot ring and the outer bag are made in to assorted corrugated surfaces for tight engagement. The mutually horizontal rotation can be automatically avoided by the utility model, which has attractive appearance.

Description

Double-layer vacuum stainless steel thermo jug

Technical field

The utility model relates to the improvement of double-layer vacuum stainless steel thermo jug, such as coffee pot, teapot, cold drink kettle etc.

Background technology

The stainless steel thermo jug of various double-layer vacuums has stainless steel kettle body and reaches the plastic cement kettle circle 1 that engages with it in the market, and plastic cement Hu Quan generally is shaped on delivery port and handle.Existing double-layer vacuum stainless steel thermo jug is even vacuumized by outer courage 2 of stainless steel and inner bag 3 welderings and constitutes, and axially welding makes weld seam 5 up, and for engaging with the grab 7 of plastic cement Hu Quan, courage neck place weldering outside connects one and takes on circle 8, as shown in Figure 1.Have following problem thus: weld seam increases the eck depth H of Hu Quan up, and the total height of kettle also increases thereupon; For not reducing the kettle body bulk, inner bag need be made bigger cancave cambered surface because the ponding effect of cancave cambered surface, when water-in-kettle is turned, need the hand-held handle very wide-angle of verting, have in addition wrist to twist 160 degree and could turn.In addition, existing stainless steel kettle body all is that horizontal plane engages with plastic cement Hu Quan, for preventing to horizontally rotate mutually, need be screwed, and the assembling trouble, outward appearance is also more stiff.

Summary of the invention

The purpose of this utility model is to provide that assembling is simple, cost reduces, in use wrist twisting angle reduce, the double-layer vacuum stainless steel thermo jug of good looking appearance.

The utility model is achieved through the following technical solutions: a kind of stainless steel thermo jug of double-layer vacuum; Have the stainless steel kettle body of double-layer vacuum and the plastic cement Hu Quan that engages with it; It is characterized in that the outer courage of kettle body and the weldering of inner bag even make weld seam inwardly along bending inwards; The neck of outer courage is shaped with scrobicular ring; The grab that is shaped with in the plastic cement Hu Quan groove down snaps in the scrobicular ring of above-mentioned outer courage neck when firmly pressing down; This scrobicular ring has enough mechanical strengths to guarantee that the plastic cement Hu Quan that engages with it firmly coincide

Hu Quan down the groove oral area and inner bag between sealing ring is set.

Move in the minimum place of the oral area of inner bag and make inner bag make basically taper type.

Plastic cement Hu Quan bottom surface and outer courage top shoulder are made the corrugated surface that matches, and both are closely connected to coincide.

The utility model is because the weldering of outer courage and inner bag connects neck along bending inwards, and the one, the eck degree of depth h of plastic cement Hu Quan reduces, and under the prerequisite of assurance kettle body bulk, moves on the inner bag oral area, forms taper type basically.To the actual measurement of shape shown in the embodiment, just water-in-kettle can be turned about wrist twisting 125 degree; The 2nd, Hu Quan highly reduces, and Hu Quan groove down is more shallow, and the neck scrobicular ring of outer courage constitutes the shoulder circle that engages with Hu Quan simultaneously, saves material, reduces cost.In addition, it is closely connected identical that Hu Quan bottom surface and outer courage top shoulder are made the corrugated surface that matches, good looking appearance, also avoided automatically horizontally rotating phenomenon mutually, need not to be screwed, assembled easy, as long as Hu Quan is firmly pressed down, the neck scrobicular ring that makes the interior grab of kettle circle groove snap in outer courage gets final product.

The specific embodiment

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Embodiment 1 double-layer vacuum stainless steel thermo jug, reach the plastic cement kettle circle 1, the pot lid that engage with it by the stainless steel body and form, the kettle body is even vacuumized by outer courage 2 of stainless steel and inner bag 3 welderings and constitutes, and the neck of outer courage 2 is shaped on scrobicular ring, move on inner bag 3 oral areas and make inner bag make basically taper type, convenient turned letter.When making, outer courage 2 and inner bag 3 tops are even made weld seam 5 inwardly along the back weldering that bends inwards.The shallow grooves that plastic cement kettle circle 1 is shaped on down is shaped on several grabs 7 in it, firmly press down Hu Quan, and the neck scrobicular ring that grab 7 can snap in above-mentioned outer courage strong bonded is integral both.Be provided with sealing ring 4 between the groove oral area of Hu Quan and the inner bag 3, can guarantee only from the water outlet of kettle mouth.

The corrugated surface that matches is made with the contact-making surface and the outer courage 2 top shoulders of outer courage in kettle circle 1 bottom surface, closely connected up and down coincideing, can not rotate mutually, and good looking appearance, be illustrated in figure 2 as unimodal paddy corrugated surface, Figure 4 shows that oblique cooperation multimodal paddy corrugated surface, the level that Figure 5 shows that cooperates multimodal paddy corrugated surface, and mark 6 is a concordant profipole among the figure.
