Description

Vacuum vessel

Technical Field

The utility model belongs to the technical field of household utensils articles for use, especially, relate to a vacuum household utensils.

Background

In our lives, the application of vacuum vessels is relatively wide, such as vacuum thermos cups, thermos flasks, heat preservation bowls and the like, and after the vacuum vessels are vacuumized without tails, black brazing solder is generally left at vacuumized parts for sealing exhaust holes. At present, in order to shield black brazing materials, metal sheets, silica gel pads, plastic outer layers and the like are generally adhered, so that the whole body is not attractive enough.

In the existing vacuum vessel with a three-layer structure, as in the patent technical scheme of the publication No. CN206228136U, the top of the middle container is welded with the inward-inclined part at the top of the outer container, and the opening part of the inner container is bent outwards to form a downward-folded part which is welded with the root platform of the outer wall of the inward-inclined part. According to the scheme, the downward folding part and the inward inclining part are required to be formed in the mouth parts of the inner container and the outer container respectively, the structure is complex, and the processing is troublesome.

Disclosure of Invention

The utility model aims at providing a vacuum vessel which has good aesthetic degree, simple structure and convenient processing.

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

The utility model provides a vacuum vessel, is equipped with inlayer, middle level and skin by interior outside to in proper order, middle level bottom is equipped with evacuation portion, the cavity evacuation between inlayer and the middle level forms the vacuum layer, the oral area of inlayer is rolled over outwards and is equipped with the hem, the middle level connecting portion welded connection that is equipped with on the middle level oral area be in the hem bottom surface, the outer connecting portion welded connection that is equipped with on the outer oral area be in the outward flange of hem bottom surface.

The folded edge of the inner layer opening which is folded outwards is horizontally arranged.

The middle layer connecting part and the outer layer connecting part are both vertically arranged and are perpendicular to the folded edge.

The body part of the inner layer is of an arc structure, and the vacuumizing part avoids the arc bottom of the inner layer and protrudes towards the inner layer.

Compared with the prior art, the beneficial effects of the utility model are that: by adopting the technical scheme, the opening part of the inner layer is turned outwards to form the folded edge, the middle layer and the outer layer are welded and connected on the bottom surface of the folded edge through the connecting part, the inner layer can be welded only by being placed on the middle layer and then the outer layer, and the welding is finished, so that the welding processing is very convenient; the vacuumizing part is arranged on the middle layer, the outer layer is arranged outside the middle layer and can shield black brazing materials, and the welding position is at the mouth part, so that obvious welding marks cannot be left on a vessel body, and the integral attractiveness of the vessel is better. In addition, the outer layer can also protect the welding position between the folded edge and the middle layer connecting part, and the welding position is not easy to be desoldered to cause vacuum failure when falling or colliding. The outer layer also has the function of improving the heat preservation performance.

The further beneficial effects are that: the hem level sets up, and middle level and the vertical setting of outer oral area connecting portion, and the horizontal hem is simpler for the lower folding portion of turn-ups, also processes more easily, and vertical connecting portion also is simpler and process more easily than the portion of falling in.

Still further beneficial effect is: the body of inlayer can set to the circular arc structure, increases pleasing to the eye degree, changes simultaneously cleanly, reduces sanitary dead angle.

Detailed Description

The utility model relates to a vacuum vessel which is suitable for vacuum cups and kettles, in particular to vacuum bowls; it is equipped with inlayer 1, middle level 2 and skin 3 from inside to outside in proper order, and inlayer 1, middle level 2 and the material of skin 3 can be stainless steel or titanium, and the bottom of middle level 2 is equipped with evacuation portion 22, and the cavity evacuation between inlayer 1 and the middle level 2 forms vacuum layer 4, and the oral area of inlayer 1 is outwards turned over a book and is equipped with hem 11, and middle level connecting portion 21 welded connection that is equipped with on the 2 oral areas of middle level is in the bottom surface of hem 11, and the outer connecting portion 31 welded connection that is equipped with on the 3 oral areas of skin is at the outward flange of the 11 bottom surfaces of hem. The outer layer 3 can shield the exposed black solder left on the vacuum-pumping part 22 of the middle layer 2 after vacuum-pumping, so that the whole vacuum vessel is more beautiful. In addition, the outer layer 3 can protect the welding part between the folded edge 11 and the middle layer connecting part 21, and the welding part is not easy to be detached to cause vacuum when falling or colliding.

The hem 11 that the mouth part of the inner layer 1 turns over outwards is horizontally arranged, and the middle layer connecting part 21 and the outer layer connecting part 31 are both vertically arranged and are perpendicular to the hem 11. The structure is more convenient for welding.

The body part of the inner layer 1 is of an arc structure, the arc structure is more attractive, more sanitary and easy to clean, the shapes of the middle layer 2 and the outer layer 3 are matched with those of the inner layer 1, and the bottom is a plane, so that the middle layer and the outer layer can be stably placed on a table top; evacuation portion 22 establishes on the bottom plane and avoids the circular arc bottom of inlayer 1 and holds the chamber to the protruding formation of inlayer 1, and the intracavity is held in the exhaust hole locating. The holding cavity formed by the protrusion of the vacuumizing part 22 is used for placing brazing solder and holding black brazing solder for melting and sealing the exhaust hole after vacuumizing.

The processing method comprises the following steps: forming an inner layer 1 with a circular arc structure on the body by machining, and turning the opening of the inner layer 1 outwards to form a horizontal folded edge 11; the middle layer 2 matched with the shape of the inner layer 1 is formed by metal processing, the bottom is a plane, an accommodating cavity and an exhaust hole are processed on the plane of the bottom of the middle layer 2 deviating from the central position to avoid the arc bottom of the inner layer 1 to form a vacuumizing part 22 protruding towards the inner layer 1, and then a middle layer connecting part 31 at the opening part of the middle layer 2 is shaped to be vertical; the outer layer 3 matched with the middle layer 2 in shape is formed by metal processing, the bottom is a plane, and then the outer layer connecting part 31 of the opening part of the outer layer 3 is shaped to be vertical; welding and fixing the middle layer connecting part 21 on the bottom surface of the folded edge 11, inversely placing the folded edge into a vacuum furnace, vacuumizing a cavity between the inner layer 1 and the middle layer 2 to form a vacuum layer 4, and then, leaving black brazing materials in a vacuumizing part 22; and then the outer layer 3 is welded and fixed on the outer edge of the bottom surface of the folded edge 11 through the outer layer connecting part 31, at the moment, the black brazing solder left by the vacuumizing part 22 is shielded by the outer layer 3, and the vacuum vessel forms an attractive whole.
