Description

Heat-insulating container with bottom sealed by gluing

Technical Field

The utility model relates to the field of small household appliances, in particular to a heat-insulating container with a bottom sealed by gluing.

Background

The existing heat preservation containers, such as thermos bottles, thermos cups and the like, are isolated from the outside by applying a vacuumizing technology to a double-layer structure and forming a vacuum heat preservation layer to prevent heat in the containers from dissipating. In the prior art, a double-layer vacuumizing heat-insulating container is mostly made of metal materials and is convenient to carry outside.

In order to further endow more functions to the traditional heat preservation container, the prior art replaces the traditional cup bottom with a functional base with the functions of heating, cooling, stirring and the like by a mode of replacing the bottom on the basis of using a vacuum heat preservation layer with a double-layer structure, so that the traditional heat preservation container is upgraded into a multipurpose heat preservation container with special functions.

However, during the process of bottom replacement, the first problem to be solved is the sealing problem between the vacuum-pumping heat-insulating layer and the multifunctional bottom fitting piece. After the bottom fitting piece replaces the common bottom, the bottom fitting piece is usually a metal shell wrapped with various modules such as an electric control element and the like, so that the bottom fitting piece is not suitable for high temperature, and the cup body with the vacuum heat-insulating layer is not suitable for a high-temperature process; the prior art can not popularize the technology of connecting the bottom matching piece with the cup body with the vacuum insulation layer in advance before vacuumizing, so that the cup body with the vacuum insulation layer and the bottom matching piece are difficult to be combined in a traditional welding mode.

The prior art is not enough to form effective sealing by means of buckling or screw thread fixing, so the sealing effect is usually enhanced by means of gluing. The bottom matching piece is matched with the cup body with the vacuum insulation layer in a tight fit mode, so most glue can be extruded out along the matching surface in the assembling process after gluing. Because the glue flows uncontrollably, and the gap left by tight fit is smaller, the glue can not completely fill the existing small gap, and the cup body with the vacuum insulation layer and the bottom matching piece can not obtain the expected sealing effect after being glued.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome at least one defect (deficiency) of the prior art, and provides an insulation container with a glued and sealed bottom, which is used for solving the problem that a bottom fitting piece and a cup body with a vacuum insulation layer are not good in sealing effect after being glued, and improving the sealing effect of the glued bottom fitting piece and the cup body.

The utility model adopts the technical scheme that the heat preservation container with the bottom sealed by gluing comprises: the vacuum cup comprises a cup body with a vacuum heat-insulating layer and a bottom matching piece arranged on the lower portion of the cup body, wherein at least one glue containing groove is formed between the cup body and the bottom matching piece, an adhesive material is filled in the glue containing groove, and a sealing layer is formed between the cup body and the bottom matching piece.

According to the bottom fitting piece with the machining precision difference of the fitting surface of cup, can select to set up arbitrary appearance gluey groove or set up two kinds of appearance gluey grooves simultaneously to further promote the bottom fitting piece with the sticky sealed effect of cup.

In the technical scheme, the first glue containing groove is formed by incomplete contact caused by the shape difference of the matching surfaces of the cup body and the bottom matching piece.

The incomplete contact of the matching surfaces caused by the shape difference means that the surfaces of the cup body and the bottom matching piece cannot be completely attached due to different structures such as different gradients or different chamfers of the matching surfaces after the cup body and the bottom matching piece are matched through design. The known positions in the matching process, where the sealing gap cannot be formed through tight matching or leakage often occurs, are enlarged through design, so that the positions with poor contact and difficult sealing have larger space, the adhesive material can be more easily stopped and stored in the positions, and the sealing effect between the bottom matching piece and the cup body is improved through guiding and enhancing the effect of the adhesive material on the positions.

In the technical scheme, the second glue containing groove is formed in the outer surface of the inner wall of the cup body and/or the outer surface of the bottom fitting piece.

The glue containing groove can retain more adhesive materials in the gluing process before matching; in the matching process, excessive overflow glue is discharged outwards along the matching surface, after the glue containing groove is arranged, the overflow glue near the matching surface of the glue containing groove is extruded and stored in the glue containing groove in the assembling process, and the adhesive material is accumulated in the glue containing groove to form a circle of annular sealing layer, so that the sealing effect between the bottom matching piece and the cup body is further improved.

In this technical scheme, first appearance gluey groove and second appearance gluey groove are the annular groove. The annular groove enables the adhesive material to be solidified to form end-to-end sealing layers, and the whole sealing effect can be improved.

In this technical scheme, the bottom of annular groove is the arcwall face. The arcuate surfaces facilitate the flow of the adhesive material in the recess to concentrate at the lower edge of the notch to substantially fill the gap between the cup and the bottom fitting.
