Abstract

The utility model discloses a vacuum thermos cup which comprises a shell and an inner container, wherein the inner container (1) is a stainless steel-titanium alloy composite layer, the inner surface (11) of the inner container is made of a titanium alloy material, and the outer surface (12) of the inner container is made of a stainless steel material; the inner container (1) is coaxially sleeved in the shell (2) and forms a gap (3) with the shell, and the opening of the inner container is sealed with the shell into a whole through a brazing process. The inner container adopts a stainless steel-titanium alloy composite structure design, not only keeps the high-quality of the titanium alloy inner container, but also solves the problem of the tightness of the inner container and the shell.

Description

Vacuum thermos cup

Technical Field

The utility model relates to the field of cups, in particular to a vacuum heat-preserving cup.

Background

The cup material of the vacuum thermos cup on the market at present is mostly stainless steel shell, and the inner bag uses stainless steel inner bag or titanium alloy inner bag as the main, when the shell adopted stainless steel material, if the inner bag is titanium alloy material, then adopted the brazing process sealed back, can appear sealed the scheduling problem that drops or the leakproofness is not good.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art, and provides a vacuum thermos cup, wherein an inner container of the thermos cup adopts a stainless steel outer layer and a titanium alloy inner container layer, so that the high-quality of the titanium alloy inner container is maintained, and the problem of the sealing property of the inner container and a shell is solved.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a vacuum thermos cup comprises a shell and an inner container, and is structurally characterized in that the inner container is a stainless steel-titanium alloy composite layer, the inner surface of the inner container is made of a titanium alloy material, and the outer surface of the inner container is made of a stainless steel material; the inner container is coaxially sleeved in the shell and forms a gap with the shell, and the opening of the inner container is sealed with the shell into a whole through a brazing process;

the stainless steel material of the opening part of the inner container extends upwards independently to form a welding part which is sealed by brazing with the shell. Furthermore, the stainless steel material of the opening part of the inner container independently extends upwards to form a welding part which is in braze welding and sealing with the shell.

Further, the shell is made of stainless steel.

Further, the bottom of shell is equipped with the exhaust hole, the exhaust hole is used for clearance cavity evacuation, and after the evacuation, the exhaust hole passes through the brazing flux and seals.

Compared with the prior art, the utility model has the beneficial effects that:

the inner container adopts the stainless steel outer layer and the design of the titanium alloy inner container layer, thereby not only maintaining the high quality of the titanium alloy inner container, but also solving the problem of the tightness of the inner container and the shell.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Reference is made to fig. 1-3.

Embodiment 1 is an inner container of a vacuum thermos cup, which is characterized in that the inner container 1 is a stainless steel-titanium alloy composite layer, that is, the inner surface 11 of the inner container is made of a titanium alloy material, and the outer surface 12 of the inner container is made of a stainless steel material.

Wherein, in order to facilitate the inner bag to realize sealed with the shell, the inner bag is upwards extended alone by stainless steel material at the oral area, forms the welding part sealed with the shell brazing to be convenient for the welding of shell and inner bag.

Embodiment 2 a vacuum thermos cup, including stainless steel's shell 2 and inner bag 1, inner bag 1 is as shown in embodiment 1, inner bag 1 coaxial cover in shell 2, and with the shell formation clearance 3, the oral area of inner bag is sealed as an organic whole with the shell through brazing process.

Wherein, the bottom of the shell is reserved with an exhaust hole 21, in the processing process of the vacuum cup, the vacuumizing device vacuumizes the cavity of the gap 3 through the exhaust hole 21 to form a vacuum cavity, and then the exhaust hole 21 is sealed through the brazing flux.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
