Description

Vacuum cup with titanium steel composite inner container

Technical Field

The utility model relates to a vacuum cup with a titanium steel composite inner container.

Background

Vacuum cups in the current market are basically stainless steel vacuum cups, and the acid resistance and the heavy metal content of 304 stainless steel cannot meet the daily use scenes of consumers, for example, the vacuum cups are easily corroded by acid or cause heavy metal to be separated out in the process of containing tea, beverages, acidic beverages or foods, so that the health of human bodies is affected.

In recent years, the defects of the 304 stainless steel can be overcome due to the advantages of the titanium material, the vacuum cup is healthier, the titanium vacuum cup is gradually sold on the market, but the high price of the vacuum cup cannot be accepted by consumers all the time.

Then, the material of the inner container which is in contact with food is titanium, and the shell is a stainless steel thermos cup product, so that the manufacturing cost is reduced, and the human health can be ensured; however, the manufacturing method is always complex, and is mainly reflected in that the welding of two different materials, namely the titanium material inner container and the stainless steel shell, has great difficulty. For example, the technical scheme disclosed by the utility model patent with patent number 201420047402.2, a titanium alloy inner container vacuum cup and the invention patent with patent number 201310692540.6, a titanium alloy composite vacuum cup is equivalent to that an inner container layer made of a titanium material is embedded in a stainless steel vacuum cup and is used for contacting with food and beverage, the titanium material inner container is spliced with the stainless steel vacuum cup body and is fixed (mechanically combined) by a fastening ring, and the technical scheme avoids welding between titanium and stainless steel, but the titanium inner container can fall off due to damage and loosening of the fastening ring, so that certain use risk is realized; as another example, the utility model 'a double-layer vacuum vessel compounded by pure titanium and stainless steel' with patent number 201820780404.0 discloses a technical scheme that a titanium ring and a stainless steel ring are arranged, and a titanium inner container and a stainless steel shell are combined and sealed by adopting a titanium ring and stainless steel ring brazing mode, but the titanium and stainless steel welding belongs to dissimilar metal welding, and the direct welding is difficult to obtain a stable result, so that the seam is very easy to break in the later stage, and the risk is caused; also, as disclosed in patent No. 202010068652.4, the invention relates to a vacuum cup with a titanium composite inner container and a manufacturing process thereof, which adopts two layers of inner container bodies and two layers of inner container bottoms, one layer is made of stainless steel, the other layer is made of titanium, the inner container bodies and the inner container bottoms are welded correspondingly, a shell made of stainless steel is welded with the inner container made of stainless steel, the two layers of inner containers are fixed in a matching way, although the titanium inner container cannot fall off, the titanium inner container can be rotated unfixed, the welding positions are more, bad air leakage of welding seams can be easily caused, the welding seams on the inner surface of the inner container can easily store dirt and contain scale, and the vacuum cup is not easy to clean, and health is affected.
